[0043] A hemostatic sprayer 100 according to the present disclosure will be described in detail below with reference to the accompanying drawings.

[0044] As illustrated in FIGS. 1 to 8, in order to stop a flow of blood from a bleeding portion of the human body by spraying biocompatible hemostatic onto the bleeding portion of the human body, the hemostatic sprayer 100 according to the present disclosure may be configured to include a powder casing 110, a receptacle 120, a protective cap 130, a connection member 140, an adjustment valve 150, and a cover casing 160.

[0045] However, the hemostatic sprayer 100 is not limited to the above-mentioned constituent elements. The hemostatic sprayer 100 may omit one or more constituent elements and, according to need, may further include a constituent element (for example, a catheter, or the like).

[0046] The powder casing 110 is configured to be coupled to the receptacle 120 described below, to press the receptacle 120 by means of an external force, and to inject the pre-stored biocompatible hemostatic by means of gas discharged from the receptacle 120 as a result of the pressing by the powder casing 110. According to the present disclosure, it is preferred that an accommodation space 111 is formed inside the powder casing 110 in such a manner that the hemostatic in the form of powders is pre-stored.

[0047] In addition, the powder casing 110 may include an inlet port 112 and an outlet port 113 that are connected to the above-mentioned accommodation space 111.

[0048] The inlet port 112 and the outlet port 113 may be provided on different sides, respectively, of the powder casing 110. Alternatively, as illustrated in FIG. 5, a powder casing 110′ of the hemostatic sprayer according to the second embodiment of the present disclosure may be configured in such a manner that the centers of the inlet port 112 and an outlet port 113′ may lie on a straight line. However, in order for the hemostatic to be smoothly scattered due to interference of the flow of the hemostatic by an inside wall of the powder casing 110′, it is more preferred that the powder casing 110 according to the first embodiment of the present disclosure is configured in such a manner that the inlet port 112 and the outlet port 113, as illustrated in figures other than FIG. 5, have the shape of the Korean letter “┐”

[0049] At this point, the degree to which the hemostatic is scattered may have an influence on an amount of remaining hemostatic and therefore is an important factor. Functions of the inlet port 112 and the outlet port 113 will be described in more detail in terms of operation in conjunction with a supply port 121, described below, in the receptacle 120.

[0050] According to the present disclosure, the hemostatic may be chitosan or gelatin in order to form a hemostatic membrane when the hemostatic is sprayed onto the bleeding portion of the human body, but is not limited thereto.

[0051] In addition, the hemostatic may be chitosan-catechol that results from a —OH group contained in a catechol group being partially oxidized to a = 0 group, then being oxidized by 1 to 20% on a catechol group mol basis through a dehydration condensation reaction with a — NH.sub.2 group contained in chitosan, and thus being crosslinked.

[0052] Moreover, in order to form the hemostatic membrane when the hemostatic is sprayed onto the bleeding portion of the human body, the hemostatic may be polyamine or polaxamer to a terminal of which a thiol group is bonded.

[0053] Furthermore, the hemostatic may be one of the above-described compositions and may result from bonding the above-described compositions to each other.

[0054] The powder casing 110 may further include a membrane filter 114 that is interposed between the accommodation space 111 and the inlet port 112.

[0055] The membrane filter 114 performs a function of preventing the hemostatic from flowing into the receptacle 120 through the supply port 121 and preventing a foreign material from flowing into the accommodation space 111 through the inlet port 112.

[0056] The receptacle 120 compresses gas and pre-stores the compressed gas inside itself. The receptacle 120 may include the supply port 121 on one side thereof that separably connects to the inlet port 112 in the powder casing 110.

[0057] In this case, according to the present disclosure, an aerosol-type receptacle may be used as the receptacle 120. It is preferred that gas compressed and stored in the receptacle 120 is CO.sub.2 gas. However, the receptacle 120 is not limited thereto.

[0058] The supply port 121 has a function of being open as a result of the pressing by the powder casing 110. When the supply port 121 is open, the pre-stored gas is supplied with a preset pressure toward the inlet port 112. Then, the pre-stored gas flows into the accommodation space 111 through the inlet port 112. The pre-stored gas flowing thereinto scatters the hemostatic present inside the accommodation space 111 and is discharged together with the hemostatic through the outlet port 113.

[0059] Configurations of the above-described receptacle 120 and supply port 121 and operations thereof in conjunction with the powder casing 110 are the same as or similar to configurations and operations of various known butane cans or sprayers that are regarded as being of an aerosol type. Therefore, more detailed descriptions thereof are omitted.

[0060] The protective cap 130 is a cap that closes the inlet port 112 in the powder casing 110 when the powder casing 110 and the receptacle 120 are separated from each other. The protective cap 130 is separably coupled to the inlet port 112 before the inlet port 112 in the powder casing 110 and the supply port 121 in the receptacle 120 are connected to each other. Thus, the protective cap 130 performs a function of blocking a foreign material from flowing through the inlet port 112 while covering the inlet port 112.

[0061] The connection member 140 is a connector provided to use a cannula. According to the present disclosure, it is preferred that the connection member 140 is configured to be coupled to the outlet port 113 in the powder casing 110 and possibly to connect the cannula that is to be inserted into the bleeding portion of the human body.

[0062] Various known connection ports may be used as the connection member 140. The connection member 140 is not limited to a structure thereof illustrated in the drawings. The connection member may be design-changed variously within the technical scope of the present disclosure by a person of ordinary skill in the art to which the present disclosure pertains.

[0063] The cannula and a catheter not illustrated may be connected together. In this case, the cannula is used for the purpose of causing the hemostatic to flow to the catheter. The catheter may inject the hemostatic directly toward the bleeding portion of the human body.

[0064] The adjustment valve 150 is a valve that adjusts an amount of the hemostatic to be discharged through the outlet port 113. According to the present disclosure, it is preferred that the adjustment valve 150 is interposed between the outlet port 113 and the connection member 140.

[0065] The adjustment valve 150 here may be at least one of 1-way, 2-way, 3-way valves that are capable of adjusting an amount of the hemostatic to be injected by being locked or unlocked.

[0066] The cover casing 160 is configured to prevent the powder casing 110 and the supply port 121 in the receptacle 120 from being damaged. It is preferred that the cover casing 160 accommodates and covers the powder casing 110 and one side of the receptacle 120.

[0067] According to the preferred embodiments of the present disclosure, it is preferred that the cover casing 160 is configured to be fixed to the receptacle 120. To this end, the receptacle 120 may further include a first coupling member 122 that is at least one of a groove and a protrusion formed in and on the one side of the receptacle 120 in which the supply port 121 is formed, in such a manner as to have an arbitrary size. The cover casing 160 may further include a second coupling member 161 that is formed in or on one side thereof in a manner that corresponds to the first coupling member 122, and is separably coupled to the first coupling member 122.

[0068] Furthermore, the cover casing 160 may be configured to further include a first guide hole 162 and a second guide hole 163 that are for providing a pressing space, a discharging space, and a connection space even when covering the powder casing 110 and the receptacle 120.

[0069] The first guide hole 162 is formed in one side of the cover casing 160 in such a manner as to provide a space in which an outside force for the pressing by the powder casing 110 is exerted without any interference while one portion of the powder casing 110 is exposed.

[0070] The second guide hole 163 is formed in the other side of the cover casing 160 in such a manner that the outlet port 113 in the powder casing 110 is exposed. Thus, the second guide hole 163 performs a function of discharging the hemostatic up to the outside through the outlet port 113.

[0071] Therefore, using the biocompatible hemostatic in the form of powders, the hemostatic sprayer 100 according to the present disclosure facilitates an operation of stopping the flow of blood from the bleeding portion of the human body and thus improving an effect of stopping the flow of blood. Accordingly, the likelihood of bleeding reoccurring from the bleeding portion of the human body can be reduced more than is the case with a clip-based medical procedure and a high frequency-based medical procedure for stopping the flow of blood in the related art.

[0072] In addition, a structure for realizing a technique of facilitating hemostatic injection more easily may be employed through the configuration where the powder casing 110 in which the hemostatic is stored is coupled to the receptacle 120, which is an aerosol type, where the gas present inside the receptacle 120 is discharged as a result of the pressing by the powder casing 110, and where the hemostatic is discharged together to the outside as a result of discharging the gas. Moreover, through the configuration where the powder casing 110 and the receptacle 120 are easily separated and coupled according to a user’s need, the compact-type powder casing is freely portable when not in use and, at the same time, is replaceable in a more convenient manner when the hemostatic or the gas is used up. Thus, higher productivity and portability of the hemostatic sprayer can be achieved.

[0073] Moreover, there is an advantage in that a more precise and efficient medical treatment of the bleeding portion of the human body can be performed through the configuration of the connection member 140 for connecting the cannula and the configuration of the adjustment valve 150 for adjusting the amount of the hemostatic to be discharged.

[0074] Furthermore, the structural reliability of the hemostatic sprayer can be improved through the configuration of the membrane filter 114 provided in the powder casing 110 and through the configuration of the protective cap 130 that covers the inlet port 112 in the powder casing 110 in advance of coupling the powder casing 110 and the receptacle 120 to each other. Moreover, the durability of the hemostatic sprayer can be improved through the cover casing 160 covering the powder casing 110 and one side of the receptacle 120. Particularly, the cover casing 160 is configured to have the first and second guide holes 161 and 162 therein. Thus, the effect of possibly providing the space for the pressing by the powder casing 110, the discharging of the hemostatic, and the connecting of the cannula can be achieved when the cover casing 160 covers the powder casing 110 and the receptacle 120.
