DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0068] FIG. 1a shows a stool-removing apparatus 1 for removing intestinal gas to the environment, which apparatus is arranged as a separate, modular unit between the bag-side end 2 of the drainage line 12 and the stool-receiving inlet 3 of the collection bag 13. The apparatus 1 has, respectively terminally, connecting components 2a and 3a that are directed to the drainage line 12 and to the collection bag 13, with which components the apparatus 1 can be inserted into the stool-draining system in a serial arrangement, preferably in the region of the transition from the drainage to the collection bag 13 or to the stool-receiving container. A basic element 4 connects the connecting components 2a and 3a in such a way that said components are in contact with each other in a communicating manner.

[0069] Attached at the outer circumference of the wall of the tubular cylindrical basic element 4 of the apparatus is a degassing, adsorbing and/or filtering module 5 in a reversibly detachable form, or even in a form permanently connected to the basic element 4. The module 5 is nestled on the wall of the basic element 4 closed circularly as a collar, or even as a non-closed, C-shaped shell. The basic element 4 has, in the region of the connection of the filter module 5, one or more openings 6, which follow a gap-shaped intermediate space 6a, that points towards the adsorbing or filtering material and is bounded by a water-impermeable, but gas-permeable separating layer 7. The separating layer 7 can be made e.g., of a GoreTex-like material, which can be supplemented on the side facing the intermediate space 6a by a soil-repellent, for example lotus-like effect. Alternatively, a cost-effective, HME-filter-typical waterleaf paper can be used as a separating layer 7, which also acts in a water-repellent manner and at the same time is air-permeable. Conceptually, the side of the separating layer 7 facing the stool is preferably designed such that an exposure to stool does not lead to a long-term, gas-tight occlusion of the separating layer 7. Preferably on the lower end of the intermediate space 6a directed towards the bag 13, it transitions to an opening 6b in the stool-carrying or stool-removing area of the basic element 4. Stool that reaches the intermediate space 6a via the openings 6 can therefore flow via the opening 6b back into the lumen of the basic element 4. In a modification of this structural form, the stool-carrying lumen of the basic element 4 can also be connected to the intermediate space 6a solely via the opening 6b, in other words, not comprise any openings 6. The intermediate space 6a then extends from the opening 6b upwardly in a chimney-like manner, whereby the separating layer 7 lying above the opening 6b is protected from a direct stool exposure in the normal vertical position of the apparatus 1.

[0070] FIG. 1b shows an embodiment with a T-piece-like basic element 4 having a lateral leg 9 that is open toward the environment, to which the adsorbing and/or filtering module 5 is applied. In the preferred design of design of this structural form, the leg 9 is oriented upwardly in an angle of inclination N to the perpendicular or to the longitudinal axis of the basic element 4 or in the drainage direction towards upstream, of approx. 15 to 60 degrees, preferably 30 to 45 degrees. Therefore, in the case of a suspended, approximately normal vertical position of the apparatus 1 or of the unit of the stool-removing drainage hose 12, degassing apparatus 1 and collecting bag 13, the module 5 is protected from the direct influx of stool. Stool that has already penetrated into the leg 9 can drain from there, following the inclination of the leg 9, into the lumen of the basic element 4. As a supplement to the described inclination of the degassing leg, the transition to the stool-carrying lumen of the basic element 4 can be protected by a tongue 4a in the form of a curtain-like or canopy-like structure, in order to prevent the entry of stool into the degassing leg 9 even more efficiently. As shielding structure, the tongue 4a emerges, for example in the transitional region 4b between the laterally pointing leg 9 and the leg of the T-shaped basic element 4 running perpendicularly upwardly or towards upstream, from the inner wall of the basic element 4, and extends down beyond the lower transition 4c of the laterally pointing leg 9, into the leg of the T-shaped basic element 4 that runs perpendicularly downward or in the drainage direction towards downstream.

[0071] As an alternative to positioning a modular apparatus 5 between the drainage line 12 and collection bag 13, as a functional unit that can be connected serially if necessary, the basic element 4 can also be integrated in a fixed design directly into the upper inlet region 3 of the collection vessel 13. In the case of a bag-like container 13, the foil body thereof is connected with a tight seal by a direct welding or adhesion to the downwardly oriented leg of the T-piece that is pointing to the bag 13.

[0072] FIG. 1c shows an embodiment of the apparatus 1 based on FIG. 1b, in which the adsorbing and/or filtering material in a fixed design has already been integrated into the lateral gas-removing leg 9 of the T-piece-shaped basic element 4 that opens the entire system of the drainage 12 and bag 13 towards the environment. The leg is thereby dimensioned in such a way that it accommodates e.g., approx. 5 to 10 mL of activated carbon granulate. The carbon granulate is sectioned off from the stool-carrying, upper and lower legs of the T-piece-shaped basic element 4 by a gas-permeable, water-repellent separating layer 7. The front-side opening of the leg 9 is provided with a cap-like closure, which has openings 5a for the outlet of gas to the environment.

[0073] FIG. 2 shows a design of the apparatus 1, wherein the outlet of intestinal gas is established by a hose-like or tubular insert 10, which is inserted into the stool-removing unit. The insert 10 is inserted via an opening 11 designed with a custom fit, which in an unused state is sealed for example with a cap-like element. In the preferred embodiment, the distal end of the insert 10 is pushed forward into the stool-receiving internal area of the bag 13, wherein it potentially projects beyond return-inhibiting foil layers 13a, so that the foils do not impede the retrograde oriented removal of gas from the bag 13 and therefore can remove gas that has already reached the bag to the environment. The proximal end of the insert 10 terminally comprises a permanently attached adsorber and/or filter module 5. The insertion takes place optionally in the region 2 of the stool-removing catheter hose 12 that is close to the bag, preferably however in the region of the connection of the drainage catheter 12 to the collection bag 13, for example through an opening integrated into the respective connector or portions of the connector. In the preferred design, the insert 10 has large-lumen openings 10a as much as possible, which discharge above the return-inhibiting foils 13a in the stool-carrying area. The hose-like or tubular portion of the insert 10b, which extends beyond the return-inhibiting foils into collecting area of the bag 13, is preferably provided with a smaller lumen, in order to restrict a possible backflow of liquid content. The module 5 is positioned approx. 10 cm above the opening 11, in order to prevent a contamination from the bag contents in the case of the normal vertical position of the bag 13.

[0074] FIG. 3a shows an embodiment of the gas-discharging apparatus 1 corresponding to FIG. 1b with a T-piece-like basic element 4, wherein a module 5 with adsorber material and/or filter material is mounted on the lateral leg 9 with a tight seal. In the interior, the module 5 comprises lamellar structures 16, which lead the gas flowing out of the system gas as efficiently as possible, in the case of the best possible use of the odor-absorbing and/or filtering capacity, from the module base 14 to the module cover 15 through the module contents. The lamellae 16 can be for example horizontally offset, intertwined like fingers or even be guided in a spiral-shaped or helical manner. In the preferred case, the module 5 is arranged at the basic element 4 in such a way that the leverage that the module 5 exerts on the unit of the drainage catheter 12, degassing apparatus 1 and collecting bag 13 is kept as small as possible, and a forward tilting of the unit that is normally fastened in a suspended manner is thus prevented. The module 5 should have a correspondingly flat design that nestles the basic element 4 as much as possible and ideally is not offset from the center of gravity. The content of activated carbon in the module 5 of the described design should be at 20 to 100 mL, preferably at 30 to 50 mL.

[0075] FIG. 3b shows a combination of an adsorber or filter corresponding to FIG. 1a that is permanently built into the lateral leg 9, wherein an accessory, filtering and/or adsorbing filter cartridge 5b can be mounted in a reversibly detachable manner on the leg 9 as an additional unit. The cartridge 5b is provided to optimize the seal in the joining area between the leg 9 and the cartridge 5b with a sealing lip or an O-ring-like seal 5c. The gas escaping on the front side from the leg 9 is admitted via corresponding openings 5d in the bushing-like depression of the base of the cartridge 5b, and channeled through lamellar webs 16, in line with a most efficient possible adsorption through the adsorbing or filtering mass. In order to prevent the escape of microbes or viruses from the system into the environment, appropriate spore-proof, bacteria-tight and virus-proof filter material 5e is upstream of the outlet openings of the cartridge cover.

[0076] FIG. 3c shows a special form of the gas guidance through the filter material or the adsorber material, wherein the interior of the module 5 is provided with a spiral-shaped or snail-shaped separating wall 16a, which expands from the center or from the inlet opening towards the outside and opens terminally to the environment via another opening 17. To prevent the escape of infectious pathogens such as viruses or bacterial spores, an appropriate filtering material 5e is upstream of the opening 17.

[0077] FIG. 4 shows a hose-like or tube-like, flexibly, or rigidly designed component 21, whose end 21a that is turned toward the patient is permanently attached at the inner wall of the basic element 4, preferably in the region of the lateral leg 9, and whose proximal end 21b is immersed into the stool-collecting area of the collection vessel 13 beyond the lower end of the basic element 4. The component 21 is thereby able overcome return-inhibiting components, such as for example lobe-like foil layers 13a, which fit closely with each other with a tight seal and act in a valve-like manner, so that intestinal gas that has penetrated into the bag 13 through the lumen of the component 21, and/or along the outer side of the component 21, can be emptied preferably directly into the gas-discharging leg 9 of the apparatus 1.

[0078] FIG. 5 shows a further structural form of an apparatus 1 according to the invention, wherein the T-piece-like basic element 4 is integrated permanently into the inlet portion 3 of the bag 13, preferably welded or adhesively secured. The lateral leg 9 is provided with a bayonet-like closure mechanism 9a, which corresponds to the closure mechanism 2a for connecting the drainage catheter 12 to the bag 13. During the phase of stool collection, the lateral leg 9 is closed with a closure cap 19. The cap 19 integrates a cartridge 20 with filter material 21 based on an activated carbon. Corresponding to the preceding designs, the free opening of the leg 9 is provided with a gas-permeable, but water-repellent and/or soil-repellent separating layer 7, which prevents the escape of stool from the T-piece-like basic element 4. The closure cap 19 is connected to the leg 9 in a gas-tight sealing manner. The cap 19 terminally comprises an opening 22 for the outlet of gas. As an alternative to a cartridge-like vessel, the internal area of the cap 19 can be filled directly with carbon or adsorber material or filter material, wherein the filled area on both sides 23a and 23b can be sealed for example with stable, but gas-permeable separating layers made of porous sintering material. In the case of using an activated carbon, the installed volume is 4 to 10 ml, preferably 5 to 6 mL.

[0079] If the bag 13 is disconnected from the drainage 12 and disposed of, the closure cap 19 is detached from the leg 9, is placed on the connector 2a and connected there with a tight seal. The separating layer 7 then prevents the free outflow of liquid through the lateral leg 9.

[0080] In order to impede the penetration of removed stool into the lateral leg 9, a tongue 4a protecting the transition from the stool-carrying path to the laterally branching leg 9 is also attached inside the T-piece-like basic element 4 in the form of a curtain-like or siphon-like structure.

[0081] In order to remove intestinal gas that has already penetrated into the collecting area of the bag 13, or in order to convey gas back into the T-piece-shaped basic element 4 upstream from the return inhibition via a return-inhibiting function integrated in the collecting bag 13, such as for example return-inhibiting foil layers 13a, and to conduct it from there through the adsorber and/or filter 5 to the environment, the T-piece-shaped basic element 4 has on the proximal end thereof a rod-like, tube-like or hose-like extension 25, which extends over a return-inhibiting foil or function into the collecting bag 13. The profile of the extension 25 is designed such that gas can be conducted either around the extension 25 or through the extension 25 from the collecting internal area of the bag 13 in regions of upstream of the bag 13. In the described structural form with a T-piece 4 integrated permanently into the inlet portion 3 of the bag 13, it is possible in an advantageous manner to dispense with an outlet that is commonly integrated directly into the bag wall in conventional collection bags 13. Outlet components that are integrated inside the collecting compartment into the wall thereof are especially problematic when the collection bag 13 gets into a flat horizontal position and the bag contents then potentially wet or saturate the filter whereby the filter loses its degassing function partially or completely.

[0082] FIG. 6a shows a modified structural form of a module 5, 5b, which, besides an adsorbing and/or filtering effect, comprises a function that releases an aromatic substance. The release of substances that act in a perfuming manner or that mask unpleasant odors takes place from a compartment 26, which is integrated into the housing of the module 5, but is continuously separated from the adsorbing or filtering medium thereof. Inserted into the compartment 26 is an absorbent storage component 27 made for example of multi-layered pressed cellulose, which absorbs the aromatic substance over its correspondingly large total surface area and releases it in a delayed manner via its front surface pointing to the environment. The compartment 26 can be sealed with a peel-off foil 28. The release of an aromatic substance can also take place from a separate, for example capsule-alike container 28, which is inserted into a corresponding trough-like recess of the module 5. The respective aromatic substance can be selected by the user from a plurality of fragrance variants and be replaced.

[0083] FIG. 6b describes an accessory dispenser module 29, which is placed directly on the gas-discharging opening 30 of the apparatus 1 or of the T-piece-like basic element 4 or is arranged directly downstream from it, and continuously releases odor-neutralizing aromatic substances in the immediate outlet region of the apparatus 1 via an integrated substance-releasing function. In this special embodiment, intestinal gas that escapes from the apparatus 1 or the stool-draining entire system through the gas-discharging opening 30 passes through a non-woven-like, large-pored or wide-meshed fabric 31, which absorbs the aromatic substance in a similar manner as a wick from a reservoir component 32 and dispenses it via the correspondingly large surface of the porous or also meshed structure of the non-woven into the escaping gas and thus masks the odor-active ingredients thereof by means of correspondingly effective pleasant aromas.

[0084] The released aromatic substance is preferably based on volatile, oil-based solutions with sufficiently good running properties in the releasing non-woven. The reservoir 32 that is connected to the non-woven-like fabric 31 consists for example of a felt-like or sponge-like component, and can optionally be refilled with aromatic substance via a small-lumen opening 33 from the outside, for example through an ampule-like container that can be squeezed between the fingers, directly before the combination of the module 5 with the drainage apparatus 1 or with the T-piece-like basic element 4. With this system, the user can select between several fragrance variants. Furthermore, when switching the collection bag 13 or the entire system, the user can remove the module 5 from the bag 13 or from the system and transfer it to a new bag 13 or a new system. The module 5 can thus be used in the case of a patient over the total duration of use of the drainage apparatus 1. Once the reservoir is depleted, it can be filled again with aromatic substance through the opening.

[0085] Therefore, the invention describes an apparatus, which can be used as an accessory or be integrated permanently into a system for removing stool or other excretions or secretions, for absorbing and/or filtering gases, which collect for example in the course of a continuous closed stool removal within a stool-draining system, and wherein said gases are dissipated or decompressed without releasing unpleasant odors to the environment, wherein the apparatus is structurally arranged in series or in parallel to the stool-removing system, wherein the removal of the gas to the environment takes place outside of the collecting area of the collection vessel 13, and the respective gas-discharging component or function cannot be contaminated with the collected contents and consequently be rendered non-functional.

[0086] The removal of the gas to the environment preferably takes place directly above the collecting area, for example in the stool-removing hose of the system to the collecting area.

[0087] Gas that has already penetrated into the collection area of the vessel 13 can be removed, for example through a rod-like, tubular or hose-like extension in the region of the gas outlet and be decompressed from there.

[0088] The gas-discharging function of the filtering and/or absorbing material is maintained by a soil-repellent and/or water-repellent separating layer between the stool-removing internal area of the apparatus and the respectively connected filter module or absorber module 5.

[0089] FIG. 7 shows a special design of a double layer of foils acting valve-like in a flow-directing manner, which double layer of foils allows a backflow of gas from the collection container 13 into the system supplying the bag.

[0090] FIG. 8 shows an angular holding apparatus for securing the bag in a vertically suspended position, wherein the backflow of the bag contents into the system supplying the bag is impeded in the case of a transient flat position of the bag.

[0091] FIG. 7 shows an arrangement of two foil layers 13ax and 13ay adjacent to each other in a planar manner and acting valve-like in a flow-directing manner, which are mounted in the interior of the collection container 13. Material M draining to the collection vessel enters through the two foil layers into collecting area S of the container. If the vessel fills up to the height of the two foil layers or beyond said foil layers when it is in the vertically suspended or normal upright position, the liquid contents cause a lip-like closure of the foil layers, and the undesired outflow or backflow of the contents from the collection container through the supplying opening is prevented. A corresponding effect occurs if gaseous substances get into the collection vessel. The gas filling likewise results in the tight seal of the two foil layers, whereby the gas accumulates successively in the vessel and the eventually resulting closing pressure on the two foil layers is pronounced in such a way that a further influx of liquid contents into the collecting vessel is no longer possible. Without a corresponding structural modification of the anti-blowback function, the collection vessel must be replaced in this case. In order for gas that has already penetrated into the bag to be removed from the bag, the invention provides specially designed foil layers, which even though they are impervious to liquid, they allow gas to pass through freely. The foil layers can be planar, e.g., consisting completely of an appropriate material, or also comprise the corresponding properties only proportionally in specific segments. The gas-permeable function or unit is placed advantageously there, where a complete closure of the two foil layers is precluded for mechanical reasons even in the case of maximum filling of the vessel. This is given in the region of the connection or the transition 3a of foil layers to a tubular or spout-like infeed segment or connector segment, where the sealing foil layers for example are welded on or adhesively secured. In the case of an outside diameter of the supplying element of approx. 15 to 25 mm, normally a gusset-shaped, open, non-closing region Z arises even in the case of the maximum filling of the vessel, which region comprises a height of at least 5 to 15 mm, and therefore offers sufficient area for the described function or integration of a “gas-permeable separating layer” T. As an alternative to gas-permeable foil material, a small, free opening O, of 1 to 2 mm diameter for example, can also be positioned in the gusset-shaped region Z. In the preferred case, however, a simple or cross-shaped slit can be made with a sharp blade in the described gusset-shaped region, wherein the legs of the slit comprise respectively a length of approximately 5 mm. Even though the slit cannot completely prevent the backflow of content into the segment above the collecting area, it does rule out a higher volume backflow of the already collected contents however.

[0092] FIG. 8 shows an embodiment of a bag-like collection vessel 13, wherein, in a horizontal position of the bag 13, the outflow of the bag contents into the supplying segment 4 of the bag 13 is impeded, reduced or prevented by means of a ramp-like slope R of the supplying segment 4. For this purpose, the angular hook 34 for the vertically suspended fastening of the bag 13 is designed in such a way that it brings the supplying or also the gas-discharging segment 4 into a diagonally ascending directed position relative to the flat horizontal bag 13. The resulting slope ensures that the liquid bag contents ideally do not reach the gas-discharging opening L in the supplying segment 4 of the collection bag 13 over a certain phase of the flat storage of the bag 13. The angular hook 34 is preferably designed to be double-sided and be fused on both flat sides of a bag 13 made for example of two layers, so that the desired inclination occurs in even in the case of the flat storage of the bag 13. In the preferred design, the hook 34 or the double hook is attached at a fixed 90 degree angle to the bag surfaces. The 90 degree position required for the inclination can also be achieved by an axially rotatable mounting bracket that can swivel into the 90 degree position and engage there.
