DETAILED DESCRIPTION OF THE INVENTION
[0100] Blood, which is a liquid connective tissue, is a polydisperse systemsuspension of blood cells (erythrocytes, platelets, white blood cells) in plasma (where proteins form a colloidal solution, but other organic substances and inorganic salts form a true solution). Blood plasma is 5% of body weight consists of water (90%), proteins (7.8%), among which are albumins (70%), globulins, fibrinogen and blood coagulation factors (II, V, VIII, X), fats (0.8-1%), glucose (0.12%), urea and uric acid (0.5%), minerals (0.9%), mostly NaCl, salts of Ca, K, Mg. This concentration is maintained at a constant level. Proteins provide a blood viscosity, latter increases with water loss, which can lead to blood clots formation. The buffer system of blood (pH=7.2-7.4) for 15% provided by blood proteins (by zwitter-ion balance between their amino and carboxyl groups), and for 85% by weak acids and their salts (mainly carbonate and phosphate buffers).
[0101] From this it is clear that in addition to launching a native blood clotting mechanism, any action leading to blood concentration (increase of viscosity) by rapid removal of water, binding (removal) of inorganic salts and drastic changes in pH inevitably lead to proteins coagulation therefore facilitate hemostasis of blood, except coagulation of blood clotting factors and removal of calcium ions.
[0102] The natural process of blood clotting (hemostasis) is an enzymatic chain process in which on the matrix of phospholipids, which are debris (fragments) of membranes of damaged cells, walls of blood vessels, tissues, blood cells, and get into the blood, sequentially are activated clotting factors and formed their complexes. Phospholipids of cell membranes act as catalysts of interaction and activation of clotting factors accelerating the progress of the hemocoagulation process.
[0103] Since in our case the stop severe bleeding we are interested in the mechanism of hemostasis (which takes place in three phases) to the outside (tissual) rather than internal (intravascular) blood coagulation system. External path runs by tissue thromboplastin (phospholipids) that stands out from the walls of damaged blood vessels and surrounding tissues. In the I phase the tissual platelet prothrombinase (factor V) is rapidly (5-10 s) formed, and the impetus for the formation of which is the appearance of tissual thromboplastin in blood. At once with the advent of the tissual platelet prothrombinase on the II phase as a result of prothrombin sorption on the tissual platelet prothrombinase surface prothrombin it quickly (2-5 s) transforms (under assistance of factors V, X and Ca.sup.2+) into thrombin. At the phase III the process of conversion of fibrinogen to fibrin occurs, which takes place in three stages: on the first stage under the influence of thrombin with fibrinogen forms sol like fibrin monomer; on the second stage under the influence of Ca.sup.2+ ions occurs fibrin monomers polymerization and fibrin polymer formed (soluble fibrin S); on the third stage under assistance of factor XIII and fibrynase (fibrin stabilizing factor) of tissues, platelets and red blood cells produced final or insoluble fibrin I.
[0104] Fibrynase (fibrin stabilizing factor) provides formation of strong peptide bonds between neighboring molecules of fibrin polymer that cements fibrin, increases its mechanical strength and resistance to fibrinolysis. The formation of fibrin completes the formation of blood thromb.
[0105] It is clear that at severe bleeding thromboplastin content in different areas of bleeding is different (it is evenly distributed throughout the volume of blood that flows) resulting processes occurring in different areas at different speeds.
[0106] Therefore, when creating composition hemostatic agents and devices based on it were taken into account the features of hemostasis mechanism.
[0107] As a result, a series of experiments, it was found that the hemostatic composition comprising a water-retaining, dust-suppressing binder, inorganic and organic hemostatic provides the following features of the said hemostatic composition (or hemostatic device): reducing the time of commencement and completion of thrombus formation, prevent drying-up of the clot, increased moisture retention in the clot. Because the clot formation begins at 30th second after application of the hemostatic device to a great extent bleeding stopped. Because of at the end of 2 minutes' clot formation ends there is a possibility for quick transportation the wounded to a safe place where he can obtain a quality medical care. The composition of hemostatic agents, i.e. hemostatic composition, consisting of water-retaining hemostatic agent, dust-suppressing binder hemostatic agent, inorganic hemostatic agent, organic hemostatic is made in the form of powders, solutions, suspensions, foams, paste, gel.
[0108] In contact with the blood each of performs its role (function). Given that blood is a liquid consisting of formed elements (erythrocytes, platelets, white blood cells etc.) dispersed in plasma containing different proteins (albumin, fibrinogen, etc.), amino acids and electrolytes (sodium, calcium salts) and maintained homeostasis of its components, at constant level values of pH (pH=7.2), ionic strength, viscosity. At the same time, many components contained in blood plasma (ions of calcium, fibrinogen, etc.) and erythrocytes (platelets) are a key factors for blood clotting, participating in different processes that occur during hemostasis. Therefore, it is clear that additional (artificial) violation of harmony in this sophisticated system such as blood characterized not only by its biochemical composition and biological (biochemical and physiological functions), but certain physical, physicochemical and chemical properties, can be caused in particular by the increase in blood viscosity (for example by the use of water-retaining agent, which may account for the intense suction of water (moisture) to concentrate the blood. This small, at first glance, the effect can cause varying the pH of the blood, its viscosity, ionic strength. In turn, these changes may lead to changes in the native conformation of proteins, including enzymesfactors of blood clotting, thereby activating and accelerating the process of blood clotting. In addition, the concentration of blood should facilitate and accelerate the fibrin thread formation and the formation of these spatial grid to which platelets stick. These reasons can cause destruction of the native tertiary structure of blood proteins and their coagulation, which would also contribute to hemostasis (unless coagulation of proteins factors of blood clotting).
[0109] It is also clear that the chemical compound, matter or material seriously affecting the ionic strength of blood plasma by reducing the content of electrolytes in it (or vice versa due to their substantial increase) or due to changes in pH of blood because of binding of low molecular ligands (amino acids, carboxylic acids) or vice versa, its (blood) saturation with ligands, which in addition to effects on pH can also bind to blood proteins, causing changes in their native conformation and coagulation. To these compounds, which can seriously affect the ionic strength of blood plasma belong inorganic hemostatic agents, including zeolites, activated carbon modified, some clays, ortotitanic acid etc., and various organic hemostatic, in particular, carboxymethyl cellulose, polyacrylic acid, alginic acid, etc. To these compounds, which can have a significant impact on blood pH changes belong particularly, among the hemostatic inorganic, including various modified clay mineral oxides of acidic or alkaline form surfaces, etc., and among organic hemostatic, including carboxymethyl cellulose and its salts, polyacrylic acid, polyvinylpyrrolidone, chitosan etc.
[0110] These can perform multiple functions simultaneously. For example, water-retaining (e.g., carboxymethyl cellulose, alginic acid and salts thereof) can simultaneously perform the function of binding dust-suppressing hemostatic agent, and organic hemostatic agent. Inorganic hemostatic in addition to features of significant extraneous surface for the liquid blood, accelerates the launch of blood clotting system in different (combined) mechanisms through chemical features (for example, if it contains calcium) due to the large surface contact with the liquid blood can in many points of blood volume, not only from the surface of said blood volume inwardly this volume (as is the case in the absence of hemostatic agent) run mechanism of blood clotting and especially the mechanism of fibrin fibers formation, which fetus are formed on the surface of inorganic particles of hemostatic agent, and quickly spread into the blood volume in all directions and thus form a mesh of fibrin fibers, which stick platelets and gradually formed a dense homogeneous clot.
[0111] As noted above, the effect of hemostatic on hemostasis can be as positive but negative as well. Therefore, it is important to choose not only the best quality composition of the hemostatic, but its quantitative constitution, especially taking on account that the hemostatic agents of such hemostatic composition have simultaneously multiple hemostatic functions, as discussed above. Amount of relevant hemostatic in the hemostatic composition should be sufficient, but not excessive, for the manifestation of the most positive impact on hemostasis, while the negative effects should be minimized. Besides excess of a hemostatic e.g. dust-suppressing binder, can significantly reduce or even reverse the positive effects, e.g. inorganic hemostatic agent, by blocking surface of the particles of latter and therefore the obstructing blood access to them. This should also consider the possibility of chemical and physicochemical interaction between a hemostatic comprising the hemostatic composition. The result of such interactions can be cooperative (synergic) or anti-cooperative (anti-synergic) hemostatic effect of hemostatic in the hemostatic composition.
[0112] The solution to this problem was obtained as a result of the experiments, the results of which are shown in
[0113] To compare hemostatic effects of different hemostatic agentswater-binding (dust suppression), inorganic and organic, was elected one of the key processes of hemostasis, namely the formation of fibrin fibers (filaments) and used the so-called Model of fibrinous threads (/

[0114] Samples were prepared as follows: first preparing a solution or suspension of hemostatic, mixed them and receive hemostatic composition as a solution or suspension consisting of two, three, four, etc. components. Then these compositions result into interaction with various types of substrateswoven, non-woven, knitted, using any arbitrary manners and obtain dry or semi dry samples of hemostatic devices, consisting of substrate, which impregnated with one, two, three, four, etc. hemostatic. Then obtained as described above multicomponent solutions (or suspensions) of hemostatic, i.e. hemostatic compositions, or as described above hemostatic devices result into contact with fresh blood.
Brief Description of the Methodology of the Experiment.
[0115] Samples were prepared as follows: take samples of fresh blood (the same donor) each time fresh puncture, drop of blood applied to flat substantive piece of glass with laid on top of him material and covered on top another objective lenses, ready to sample immediately put in against lenses microscope (for observing nature agglutination) and thus already observed interaction with the sample drop of blood hemostatic material (the period from the beginning of blood collection before the observation is 101 sec). This blood with that of the fences used to experiment with fibrin fiber. For this drop of blood placed on a glass slide with the deepening of the sample placed in its material. Immediately specialist special moves needle controls the appearance of fibrin fibers deep in the blood, which is adjacent to the material and records (on a timer) start the formation of fibrin fibers fibrinogen and end time of the formation of fibrin fibers in a sample of blood (drop) on the glass or on sample material, which is on the glass).
[0116] Agglutination of red blood cells under a microscope and the appearance of fibrin on lenses were simultaneously observed by two specialists on the identical samples of the same material and of the same blood. Agglutination of red blood cells was observed with microscope (Carl Zeiss company) in real time, changes in time were recorded with a timer. The procedure in all experiments was standard (the same).
[0117] In
[0118] For comparison, as control in
[0119] It was found that temporal characteristics of the fibrin thread formation for hemostatic agent (http://www.celoxmedical.com Celox) (sample No 5), made of thick non-woven substrate and chitosan, are virtually identical to the characteristics of the nonwoven carrier (sample No 2), but agglutination for the sample No 5 (unlike sample No 2) goes fast (1-2 minutes), evenly and with high density.
[0120] Unlike the HSD (http://www.celoxmedical.com/Celox) (sample No 5) HSD [U.S. Pat. No. 7,604,819 B2, U.S. Pat. No. 8,114,433 B2, U.S. Pat. No. 8,257,732 B2, U.S. Pat. No. 8,383,148 B2, U.S. Pat. No. 8,343,537 B2] QuikClot (sample No 6), also made of non-woven substrate and kaolin, significantly accelerates fibrin thread formation compared to blood samples in vitro (sample No 1) and carrier (sample No 2), and unlike these samples agglutination in case of sample No 6 (begins at 60 s ends-120 s) runs quickly and evenly, with a high density but begins and runs mainly along the fibers, possibly due to the action of kaolin particles attached to fibers.
[0121] Further, for example in
[0122] For samples made of binding (dust suppression) hemostatic agents such as carboxymethyl cellulose (sample No 12), carboxymethyl cellulose sodium salt (sample No 13), polyvinylpyrrolidone (sample No 14), unlike the samples No 7-No 11 also having binding (dust suppression) properties, there has been observed some acceleration of the fibrin thread formation compared with substrate (sample No 2).
[0123] For samples made of inorganic hemostatic agents such as bentonite (sample No 15), kaolin (sample No 16), titanium dioxide (sample No 17), barium sulfate (sample No 18) unlike previous samples, there is a substantial acceleration (especially in the case of kaolin and bentonite) of the fibrin thread formation compared to carrier (sample No 2), which is probably due to the large surface of particles of these substances contacting with blood, and the differences in their behavior due to their different chemical nature. It should be noted that the sample containing kaolin (sample No 16) for time characteristics prevails even HSD [U.S. Pat. No. 7,604,819 B2, U.S. Pat. No. 8,114,433 B2, U.S. Pat. No. 8,257,732 B2, U.S. Pat. No. 8,383,148 B2, U.S. Pat. No. 8,343,537 B2] QuikClot (sample No 6) even more the HSD (http://www.celoxmedical.com/) Celox (sample No 5) that may be explained by the presence in the sample No 6 dust suppression agent, which somewhat reduces surface contact of clay with blood.
[0124] The samples made with organic hemostatic agents, such as gallic acid (sample No 19), polyacrylic acid (sample No 20), tannin (sample No 21), showing roughly the same characteristics (
[0125] Samples of hemostatic agents, which have been made from substrate and simultaneously two hemostatic agents unexpectedly demonstrated both positive and negative cooperative hemostatic effect (synergistic action). In particular, in
[0126] Unlike of samples No 23 (bentonite-tannin), No 24 (CMC-tannin), for two-component hemostatic devices (examples No 22 (bentonite-CMC), No 25 (kaolin-chitosan), No 26 (kaolin, sodium alginate) strong positive cooperative effect observed. In particular, in the sample No 22 (bentonite-CMC) fibrin thread formation begins (t1) at 35 second and at 105 second its formation (t2) completes. The cooperative effect for sample No 22 (bentonite-CMC) appears in the process of agglutination started (t3) at 15 second and is complete along the fibers (t4) for 30 second, and 60 second is full agglutination across the surface of the sample (t5). For comparison, the corresponding characteristics of agglutination for sample number 15 (bentonite) (t3=45 C, t4=60 seconds, t5=120 s) and No 12 (CMC) (t3=40 s, t5=150S; agglutination have focal pattern with a significant number of voids (areas without agglutination)) are much worse. For samples No 25 (kaolin-chitosan), No 26 (kaolin, sodium alginate) as well as for sample No 22 (bentonite-CMC), distinct cooperative effect observed, for example, evidenced by comparing the start time (t1) and end (t2) of fibrin thread formation in sample No 25 (kaolin-chitosan) ((t1=75 s; t2=150c) with sample No 10 (chitosan) (t1=170 s; t2=240p) and No 16 (kaolin) (t1 p=110; t2=125 s) and sample No 26 (kaolin, sodium alginate) ((t1=35 s; t2=140 s) in accordance with sample No 9 (sodium alginate) (t1=140 s; t2=205 s) and No 16 (kaolin) (t1=110 s; t2=125 s).
[0127] Thus, obtained results indicate that due to cooperative (synergic) effects hemostatic agents can enhance the hemostatic action of each other. However, anti-cooperative effects can weaken the effect of certain hemostatic agents. Therefore, to obtain highly effective hemostatic device to control the severe bleeding it should to create a composition of hemostatic agents, i.e. hemostatic composition, with the optimal choice of qualitative and quantitative composition of components, functional properties of each of the agents not only complement each other but a combination of these agents in the composition would be achieved a new qualitya substantial increase of hemostatic action of the said composition and production of hemostatic device using it.
[0128] During the experiments it was found that initiation of clot formation and rapid, almost instantaneous initial moisture absorption is carried out by inorganic component, but this component has a drawback, which is relatively small dust and moisture binding. Organic components can provide significant moisture retention compared to their weight, but do not give an instant effect of moisture absorption. Moisturizers components ensure retention of a certain moisture level in absence of condensate. Certain level of humidity ensuring the mechanical properties of the material, its flexibility, prevents dust formation of inorganic component and also provides acceptable tactile properties of the material. It was also found that the differentiation of certain components is rather conditional, because certain components may belong to different groups, but their combination, based on their functional purpose in certain proportions compensates for deficiencies and increases positive qualities.
[0129] Thus, during experiments researchers has found that the optimal composition of hemostatic agents, i.e. hemostatic composition, should contain 4 groups of components:
[0130] water-retaining hemostatic agent,
[0131] dust suppressing binder hemostatic agent,
[0132] inorganic hemostatic agent,
[0133] organic hemostatic agent.
[0134] Water-retaining hemostatic is a compound selected from the group consisting of but not limited to polysaccharides and its derivatives, in particular, carboxymethyl cellulose, and/or salts and/or chitosan thereof and/or polyols including glycerol gums, in particular, locust bean, guar, xanthan, pectins and/or glycerol.
[0135] Binder dust suppressing hemostatic is compound selected from the group consisting of but not limited to: synthetic and/or natural, including modified polysaccharides, in particular, carboxymethyl cellulose, starch, agar-agar, gum arabic, dextrin, polyols in particular, glycerol sorbitol, xylitol, maltol polymer polyols, glycerol derivatives preferably, but not limited to, propylene glycols, glyceryl triacetates and/or cyclic alcohols, preferably, but not limited to, menthol, eugenol and combinations thereof.
[0136] Organic hemostatic agent is compound selected from the group consisting of but not limited to -caproic acid, tranexamic acid, amben, fibrin, polyphenols and/or its components, in particular, tannin and/or tannic and/or gallic and/or digallic acid and/or flavonoids, in particular, rutin and/or quercetin, and/or preferably selected from the group of water-soluble polymers, including natural polymers, including chemically modified natural polymers, preferably selected from the group of cellulose derivatives, gelatin, gelatinized starch, polyvinylpyrrolidone, dextrose, pectin, chitosan, agar-agar, gum arabic, collagen, polyvinyl alcohol, polyacrylic acid, and its salts silicone, polyvinyl acetate and/or group of polyols, preferably selected from the group glims, glycerol and its esters and/or plant extracts or vegetable extracts selected from the group but not limited to in particular nettle leaves (Folia Urticae), yarrow herb (Herba Millefolii); water pepper herb (Herba Polygoni hydropiperis), grass Persicaria maculosa (Herba Polygoni persicariae), Viburnum bark (Cortex Viburni opuli), arnica (Flores Arnicae) etc., and/or combinations thereof.
[0137] Inorganic hemostatic agent is compound selected from the group consisting of but not limited to water-insoluble and/or sparingly soluble oxides of natural and/or synthetic origin, chosen preferably, but not limited to the group consisting of oxides of titanium, silicon, aluminum, etc., selected preferably, but not limited to from the group consisting of attapulgite, kaolin, bentonite, etc. and/or its combinations and/or minerals selected preferably, but not limited to zeolites, including that might be part of clays, metal salts selected preferably, but not limited to, from the group consisting of calcium, barium sulfate, titanates, phosphates, glycerophosphate, etc.
[0138] Also, to ensure radiographic properties of hemostatic agent is proposed to add radiographic material. Preference is given to those radiographic substances having hemostatic properties. Such substances are preferably but not exclusively selected from the group consisting of barium sulfate, phosphate and titanate.
[0139] To visualize the hemostatic composition as any hemostatic agent or its fragments in X-rays, what is necessary to control the absence of said hemostatic composition or said hemostatic device in a wound after providing skilled care, including surgery, to prevent adverse effects caused forgotten hemostatic composition or device in the wound, hemostatic composition may contain at least one hemostatic agent having radiographic properties.
[0140] As one possible example of such hemostatic composition is composition of Example No 23, containing inorganic hemostatic agentbarium titanate, having radiographic properties. Next, as one of the possible examples (Example No 26) of such hemostatic composition containing inorganic hemostatic agentbarium sulfate, having radiographic properties. Made of such hemostatic compositions such as Example No 26, hemostatic device, is one of examples, such as hemostatic device napkin (16) (
[0141] One possible example of hemostatic composition is shown in Example No 23, and which has radiographic properties in X-rays in
[0142] As seen from
[0143] According to the requirements for such devices on undemanding to storage conditions and duration of storage hemostatic device placed into sealed packaging ensuring its sterility during shelf life.
[0144] The solution to the technical problem posed invention is to provide two objects: hemostatic compositions and container (substrate). Specifically, hemostatic composition as such and hemostatic device, which consists of said composition of hemostatic agents combined with the container (substrate), wherein container (substrate) contains said composition. It should be mentioned that capacity in the sense of the present invention is a significant set of different containers and substrates, which can be divided into two groups: the two-dimensional container (substrate) in which the value of a measurement to two other at least 10 times less than least two other and form these containers (substrates) is relatively simple (e.g. cloth, bandage, nonwoven fabric, etc.), and three-dimensional, in designs which can be quite complex, and there is no such value measurements as in two-dimensional.
[0145] Container (substrate) is agent or device which is material to any selected from the following group: cotton, silk, wool, plastic, cellulose, rayon; polymer (e.g., nylon, polyethylene, polypropylene, polyester (polyester, polycarbonate, etc.)), metal, glass, organic matter, a mixture of the above, woven, non-woven, water permeable and/or water impermeable.
[0146] Optionally, container (substrate) can be bandage, napkin, film that can be definitely folded and/or twisted and/or convoluted.
[0147] Optionally, container (substrate) can be in hermetically sealed packaging ensuring its sterility during shelf life.
[0148] Container (substrate) can be three-dimensional.
[0149] Container (substrate) can be a vessel containing the composition of hemostatic agents or said above hemostatic device or medication such as tampon, napkin, sponge at least part of, container (substrate) for the composition of hemostatic agents has a water impermeable shell. At least some container for the composition of hemostatic agents has a water impermeable shell, and the composition of hemostatic agents further comprises at least one component foam. At least part of container (substrate) for the composition of hemostatic agents may have water impermeable shell filled with a composition of hemostatic agents in the form of a gel, foam, paste. At least part of container (substrate) for the composition of hemostatic agents presented by flexible substrate e.g. gauze is fibrous and/or mesh and/or a structure with air holes, can incorporate composition of hemostatic agents in any sequence in any suitable way, particularly it impregnated with a solution and/or suspension composition of hemostatic agents used in spraying solution and/or suspension composition of hemostatic agents, and/or use slot-die process for applying the solution and/or suspension composition of hemostatic agents and/or using smearing of substrate with solution and/or suspension of the composition of hemostatic agents and/or using any combination of these methods, dried to the required moisture and applying at least portion of at least one side surface of substrate for complex of hemostatic agents with adhesive substance. Also, said device can be placed into sealed packaging ensuring its sterility during shelf life.
[0150] Hemostatic composition can have radiographic properties, can incorporate appropriate hemostatic agents having radiographic properties (radiographic agents) selected preferably, but not exclusively, from the group consisting of barium sulfate, titanate and phosphate.
[0151] As one of the possible options for providing radiographic properties of hemostatic composition and produced hemostatic device can be radiographic materials (36) selected from the group consisting of polymeric materials such as polypropylene, which is produced with the addition of radiographic agents (34), including barium sulfate and which are produced mainly in the form of fibers or tapes, which can be crushed into small pieces that can be added into the hemostatic composition to providing radiographic properties. Availability of radiographic material, e.g. said above polymer (made of polypropylene and e.g. barium sulfate) materials in the form of threads, bands, ribbons connected to the substrate (33) to produce hemostatic agent, such as device (32), as seen in

[0157] As mentioned above to ensure efficient operation of hemostatic compositions and convenience of use and retention of its properties during shelf life and transportation said composition may be connected to the container (substrate) into one wherein those connected hemostatic composition and capacity are present a hemostatic device, and wherein capacity keeps composition of hemostatic agents. Container (substrate) can be two-dimensional particularly flat or three-dimensional.

As one of the possible examples of the invention in
[0160] Hemostatic properties of the device is an integral characteristic depending on the qualitative and quantitative composition of hemostatic agents comprising the composition and the material or materials from which made substrate, its macro- and microstructure, method of manufacture, etc. Based on the fact that the substrate should provide secure fixation and maintenance composition throughout the volume and/or on the entire surface of the said device and one, but not the only of its functions is to prevent the ingress of particles composition into wound, its mechanical separation from the substrate and the flexibility of substrate so that it can repeat the geometry of the wound, substrate comprising material selected preferably but not limited to the group comprising organic material of natural origin and products of its chemical modification (cotton, silk, wool, plastic, cellulose, viscose, etc.), polymers (such as nylon, polyethylene, polypropylene, polyester, polycarbon, et al.), metal, glass fiber, organic matter; mixtures of the above; woven, nonwoven, film water permeable and/or impermeable.
