Description

  The present invention relates to a hemostatic device that presses a puncture site such as an arm to stop hemostasis.

The surgeon inserts a catheter or the like through the lumen of the introducer sheath introduced into the arm of the patient's limb or the puncture site of the leg into the lesion, such as a blood vessel, for treatment / examination. If done, it is necessary to stop the puncture site after removing the introducer sheath.
In order to stop hemostasis at the puncture site, an air injection type hemostasis device for compression is used. The band of this hemostatic device is wound around and fixed to the puncture site formed on the arm or leg, and air is injected into the balloon of this band from a syringe or the like and the puncture site is compressed by the compression force of the balloon. (See Patent Document 1).
By the way, since the hole of the blood vessel is blocked with a thrombus after a lapse of time, the blood flow of the blood vessel may be inhibited, or numbness or pain may be caused when the blood pressure is compressed with the hemostatic device. For this reason, hemostasis is performed over several hours while manually performing an operation of periodically reducing the compression force by the hemostatic device, that is, an operation of decompressing the balloon.

JP 2005-218593 A

As described above, when the compression force by the hemostatic device is periodically reduced, a syringe is used, and compressed air in the balloon is returned into the syringe. However, if the position of the pusher of the syringe is not securely held when the hemostatic device and the syringe are connected, the pusher is pushed by the air pressure, and the compressed air in the balloon of the hemostatic device enters the syringe. It may flow in at once. If the compressed air in the balloon flows into the syringe at this time, the compression force by the balloon decreases rapidly, so that the puncture site cannot be sufficiently compressed, and re-bleeding may occur from the puncture site. Because there is, the surgeon needs to be careful in handling.
SUMMARY OF THE INVENTION An object of the present invention is to provide a hemostatic device that can safely and easily reduce the compression force when a region to be hemostatically pressed is compressed.

The hemostasis device of the present invention is a belt body that is wound around and fixed to a site to be hemostasis of the limb, and is connected to the belt body, and is expanded by injecting a fluid to compress pressure for hemostasis of the site. An expansion member for supplying the fluid to the site, a connector provided at an end of an injection path for injecting the fluid into the expansion member, and a fluid supply member having a first protrusion that can be fitted to the connector; A pressure having a second protrusion that can be fitted to the connector having the same shape as the first protrusion, and for extracting a certain amount of the fluid from the expansion member when reducing the compression force of the expansion member And the connector has a valve body that closes the flow path of the fluid in the connector, and the valve body has the second projecting portion of the pressure reducing member at the connector. When inserted and connected, the second protrusion The valve body is pressed to open the fluid flow path in the connector, and the pressure reducing member has a storage chamber for storing the constant amount of the fluid, and the expansion When the member is extended, when fitting the second projecting portion to the connector, by the difference in pressure, the said fluid from the expansion member in the yield capacity chamber flows, characterized in that.
According to the above configuration, when the surgeon is performing hemostasis on the site to be stopped using the hemostatic device, the site to be stopped by the expansion member is removed by extracting a certain amount of fluid from the expansion member to the storage chamber side. It is possible to reduce the pressing force on. Specifically, the operator connects, by utilizing the difference in pressure yield capacity chamber pressure and the pressure reducing member in the extension member hemostatic device, the second protrusion of the pressure reducing member in the connector of the hemostatic device By the simple operation of doing, it is possible to reduce the compression force applied to the site to be hemostatic by the expansion member. The pressure reducing member, because the capacity of the revenue volume chamber is constant, when connecting the second protrusions of the pressure reducing member in the connector of the hemostatic device, the fluid in the expansion member only capacity of yield vessel chamber Osamu flows into the volume chamber, the pressure of the expansion member will not be reduced more than necessary. Therefore, according to the present invention, it is possible to suppress the risk of sudden reduction of the compression force of the expansion member and rebleeding. Therefore, the present invention can reduce the compression force safely and easily when the part of the limb that is to be hemostatic is pressed.
In addition, the fluid supply member and the pressure reduction member have protrusions (first protrusion and second protrusion) having the same shape that can be connected to the connector. Therefore, a medical device having a protrusion having a shape different from that of the fluid supply member and the pressure reducing member is not erroneously connected to the connector of the hemostatic device. Therefore, the surgeon can safely reduce the pressure by the pressure reducing member. This effect occurs because the protrusions of the fluid supply member and the pressure reducing member of the present invention are different from the shape of a general luer taper of a syringe.
In the present specification, “fluid” includes not only gas but also liquid.

Preferably, said pressure reducing member includes a main container having a yield vessel chamber, said expansion member and which partitions the yield vessel chamber of the main container, the yield capacity chamber and the expansion member by being moved linked with and having and a partition member for reducing the pressing force of the extension member by guiding the fluid of the expansion in the member to the yield vessel chamber.
According to the above configuration, when the operator wants to decompress a small volume of fluid from the expansion member at short time intervals, or when he wants to decompress a large volume of fluid from the expansion member at long intervals, the partition member by connecting a plurality of revenue volume chamber drawer and to adjust the volume of the yield vessel chamber of the pressure reducing member can be arbitrarily adjusted decompression of the expansion member. For example, if you want to vacuum to remove the large volume of fluid from the expansion member, by increasing the capacity of the drawer part yield vessel chamber partition plate of the pressure reducing member, a connector and a connection number of the second projecting portion This can reduce the trouble of the surgeon.
In addition, when the pressure reducing member wants to decompress a small volume of fluid from the expansion member at short time intervals, leave the second projecting portion of the pressure reducing member and the connector connected, and periodically Alternatively, the decompression of the expansion member may be adjusted by removing the partition plate.

  Further, according to the above configuration, since the present invention has the valve body in the connector, it is possible to open the fluid passage in the connector simply by inserting and connecting the second protrusion into the connector. it can. Therefore, if an operator moves a partition member, the fluid in an expansion member can be taken out through the channel | path of the fluid in a connector to the pressure reduction member side through a connector.

Preferably, the pressure reducing member includes a plurality of the storage chambers, the partition member for partitioning the expansion member and the storage chamber closest to the expansion member, and the space between the storage chambers. And the partition member for partitioning.
According to the above configuration, since the pressure reducing member has a plurality of storage chambers, the partition member for partitioning between the expansion member and the storage chamber closest to the expansion member, and each storage chamber By sequentially moving the partition members for partitioning the gaps with time, it is possible to easily reduce the compression force of the part of the limb that is to be hemostatically little by little.

Preferably, the connector expands the expansion member by injecting the fluid into the expansion member, and a first connector portion that connects the second projecting portion of the pressure reducing member fixedly or detachably. It has the 2nd connector part which connects the said 1st protrusion part of a fluid supply member fixedly or detachably.
According to the above configuration, the replacement work between the fluid supply member and the pressure reducing member becomes unnecessary, so that the operator can easily perform the pressure reducing treatment by connecting the pressure reducing member to the first connector portion. It can be carried out.

Preferably, when the partition member is pulled out to the outside of the pressure reducing member, the partition member releases a state in which the expansion member and the storage chamber are partitioned or a state in which the storage chambers are partitioned from each other. According to the above-described configuration, the operator can partition the space between the expansion member and the storage chambers by simply pulling the partition member out of the pressure reducing member or between the storage chambers. Since it can be released, the compression force reduction treatment can be easily performed.

  The present invention can provide a hemostatic device that can safely and easily reduce the compression force when the puncture site of the limb is being compressed.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.
The embodiments described below are preferred specific examples of the present invention, and thus various technically preferable limitations are given. However, the scope of the present invention is particularly limited in the following description. Unless otherwise stated, the present invention is not limited to these embodiments.
(First embodiment)
FIG. 1 shows a first embodiment of the hemostatic device of the present invention. FIG. 1 is a view showing a surface which is an inner surface side (a surface side in contact with skin) of a band body 2 when the hemostatic jig 1 is attached to, for example, a wrist, which is a site to be hemostatic of a patient's limb. FIG. 2 is a cross-sectional view showing a state where the hemostatic device 1 shown in FIG.

  As shown in FIG. 2, the hemostatic device 1 shown in FIG. 1 wraps around a wrist H that is a site to be hemostatic of a patient's limb, thereby pressing the puncture site 100 formed on the wrist H to stop hemostasis. . The puncture site 100 is formed on the wrist H for the purpose of inserting a catheter or the like for treatment or examination into the blood vessel, and the hemostatic device 1 punctures the introducer sheath that has been placed at the puncture site 100 after removing the introducer sheath. The region 100 is pressed to stop bleeding.

The hemostatic device 1 includes a band 2 for wrapping around a wrist H, a hook-and-loop fastener 3, a reinforcing plate 4, a balloon 5 as an example of an expansion member, an auxiliary balloon 6 as an example of an expansion member, and a marker 7. And a pressure reducing member 150 and a syringe 200 as an example of a fluid supply member. The hook-and-loop fastener 3 is a fixing means for detachably fixing the belt body 2 around the wrist H. The balloon 5 and the auxiliary balloon 6 are expanded by sending air.
The band 2 is a band-shaped member having flexibility. As shown in FIG. 2, the band 2 is wound around the outer periphery of the wrist H. In order to hold the band 2 around the wrist H, the overlapping portion of the band 2 is detachably fixed by a hook-and-loop fastener 3 described later.

The material constituting the band 2 is not particularly limited as long as the operator can visually recognize the puncture site 100 through the band 2. For example, polyvinyl chloride, polyethylene, polypropylene, polybutadiene, and ethylene-vinyl acetate are used. Polyolefins such as polymer (EVA), polyesters such as polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polyvinylidene chloride, silicone, polyurethane, polyamide elastomer, polyurethane elastomer, polyester elastomer, and other thermoplastic elastomers, Or what combined these arbitrarily (blend resin, a polymer alloy, a laminated body, etc.) is mentioned.
The band 2 is preferably substantially transparent. Thereby, the operator can surely visually recognize the puncture site 100 from the outside through the band 2 and can easily align the marker 7 described later with respect to the puncture site 100. Thereby, the band 2 can be accurately positioned with respect to the wrist H.

  As shown in FIGS. 1 and 2, a reinforcing plate holding portion 21, which will be described later, is formed in the central portion of the band body 2. The reinforcing plate holding portion 21 has a role of accommodating and holding a reinforcing plate 4 described later. A separate band member 21A is fused (thermal fusion, high frequency fusion, ultrasonic fusion, etc.) or bonded (adhesive) to the outer surface side of the band 2 (or the inner surface side of the band 2). And bonding with a solvent). Therefore, the reinforcing plate holding part 21 is configured to be doubled by the band 2 and the separate band 21A. Thereby, the reinforcement board 4 is reliably hold | maintained so that it may not move by inserting in the clearance gap between the strip | belt body 2 and the separate strip | belt body member 21A.

A male member (or female member) 31 of a hook-and-loop fastener 3 generally called a magic tape (registered trademark) or the like is provided on the inner surface side of the portion near the left end of the band 2 shown in FIG. A female member (or male member) 32 of the hook-and-loop fastener 3 is provided on the inner surface side of the portion near the right end of the belt body 2 shown in FIG. As shown in FIG. 2, by attaching, for example, a male member 31 and a female member 32 of the hook-and-loop fastener 3, the belt body 2 can be attached to and detached from the wrist H while being wound around the outer periphery of the wrist H. Can be installed.
The fixing means for the band 2 is not limited to the hook-and-loop fastener 3 shown in FIG. 1, but may be a snap, a button, a clip, or a frame member that passes through the end of the band 2.

As shown in FIG. 2, as described above, the reinforcing plate 4 is held by the band 2 by being inserted between the reinforcing plate holding portions 21 formed in double of the band 2. The curved reinforcing plate 4 has a shape in which at least a part thereof is curved toward the inner peripheral surface side. The reinforcing plate 4 is made of a material harder than the band 2 and maintains a substantially constant shape.
As shown in FIG. 1, the reinforcing plate 4 has a shape that is long in the longitudinal direction of the band 2. As shown in FIG. 2, the central portion 41 in the longitudinal direction of the reinforcing plate 4 is hardly curved and has a flat plate shape. On both sides of the central portion 41, curved portions 42 that are curved toward the inner peripheral side and along the longitudinal direction of the band 2 (the circumferential direction of the wrist H) are formed. The curvature radius R2 of the curved portion 42 is smaller than the curvature radius R1 of the central portion 41 (in the illustrated configuration, the curvature radius R1 is almost infinite).

The constituent material of the reinforcing plate 4 is not particularly limited as long as the operator can visually recognize the puncture site 100 through the reinforcing plate 4. For example, acrylic resin, polyvinyl chloride (particularly hard polyvinyl chloride), polyethylene , Polyolefins such as polypropylene and polybutadiene, polystyrene, poly- (4-methylpentene-1), polycarbonate, ABS resin, polymethyl methacrylate (PMMA), polyacetal, polyacrylate, polyacrylonitrile, polyvinylidene fluoride, ionomer, acrylonitrile- Butadiene-styrene copolymer, polyester such as polyethylene terephthalate (PET), polybutylene terephthalate (PBT), butadiene-styrene copolymer, aromatic or aliphatic polyamide, polytetrafur Examples thereof include fluorine resins such as oloethylene.
The reinforcing plate 4 is preferably substantially transparent. Thereby, the surgeon can surely visually recognize the puncture site 100 from the outside through the band 2 and the reinforcing plate 4, and can easily align the marker 7 described later with the puncture site 100. In addition, as a shape of the reinforcement board 4, what does not have the part which is not curved like the center part 41, ie, the thing which curves over the full length, may be sufficient.

  As shown in FIGS. 1 and 2, the balloon 5 is connected to the inner surface side of the band 2 (the side in contact with the patient's skin). The balloon 5 is made of a flexible material, and the balloon 5 is an example of an expansion member that can be expanded by injecting air (an example of a fluid). Accordingly, the puncture site 100 of the wrist H can be compressed by expanding the balloon 5 by injecting air into the balloon 5 between the band 2 and the wrist H.

  As shown in FIG. 2, the balloon 5 is connected to the inner surface side of the band body 2 via a connecting portion 11 having flexibility. Moreover, the balloon 5 is positioned on the inner surface side of the band 2 so as to be offset toward one end side in the longitudinal direction of the reinforcing plate 4. As shown in FIG. 2, the balloon 5 is positioned so as to overlap the portion on the substantially right half side of the reinforcing plate 4. The balloon 5 is formed in a bag shape by being sealed by, for example, fusing or bonding the edge of the sheet material made of the above-described material. The balloon 5 has a quadrangular shape when it is not expanded by injecting air.

  As shown in FIG. 2, the length of the connecting portion 11 is relatively short, so that the balloon 5 is positioned at a position offset from the reinforcing plate 4. The balloon 5 is preferably formed of the same or similar material as the band 2. The material forming the connecting portion 11 is preferably the same as the material forming the balloon 5. Thereby, the balloon 5 can be easily joined to the inner surface side of the band 2 by fusion using the connecting portion 11.

  The material for forming the balloon 5 is not particularly limited as long as the operator can visually recognize the puncture site 100 from the outside through the band 2, the reinforcing plate 4, and the balloon 5. In particular, the band 2 and the balloon 5 are preferably substantially transparent. Thereby, the surgeon can visually recognize the puncture site 100 from the outside through the band body 2, the reinforcing plate 4 and the balloon 5. In addition, the marker 7 can be easily positioned with respect to the puncture site 100 from the outside through the band 2 and the balloon 5.

  As shown in FIGS. 1 and 2, a marker 7 is provided on the inner surface side of the balloon 5. That is, the marker 7 is provided on the surface side that contacts the puncture site 100. By providing the marker 7 on the inner surface side of the balloon 5, the operator uses the marker 7 while visually confirming the puncture site 100 of the patient's wrist H through the band 2, the reinforcing plate 4 and the balloon 5. Thus, the balloon 5 can be easily positioned with respect to the puncture site 100. For this reason, leakage of blood from the puncture site 100 and occurrence of hematoma due to the displacement of the balloon 5 can be prevented.

  As shown in FIG. 1, the marker 7 is preferably provided around the center of the balloon 5, that is, the intersection of the square diagonal lines of the balloon 5. Thereby, since the center part of the balloon 5 can be aligned with the puncture site 100, the compression force of the balloon 5 acts on the puncture site 100 reliably when the balloon 5 is expanded. The shape of the marker 7 is not particularly limited, and examples thereof include a circle, a triangle, a quadrangle, and the like. In FIG.

The material of the marker 7 is not particularly limited, and examples thereof include oil-based colorants such as ink and resins kneaded with pigments. The method of providing the marker 7 on the balloon 5 is not particularly limited. For example, a method of printing the marker 7 on the balloon 5, a method of fusing the marker 7 to the balloon 5, and applying an adhesive on one side of the marker 7 to the balloon 5 Examples include a method of pasting.
The color of the marker 7 is not particularly limited as long as the color that allows the balloon 5 to be aligned with the puncture site 100 is used, but a green color is preferable. By using the green system, the operator can easily visually recognize the marker 7 on the blood or the skin through the band 2, the reinforcing plate 4, and the balloon 5. It becomes easier.

  The marker 7 is preferably translucent. Thereby, the operator can visually recognize the puncture site 100 from the outside of the marker 7. The marker 7 may be provided on the outer surface side of the balloon 5, that is, on the side opposite to the surface that contacts the puncture site 100 of the balloon 5 (the back side of the paper surface of FIG. 1). Further, the marker 7 may be provided not on the balloon 5 but on the band 2 or the reinforcing plate 4 or the auxiliary balloon 6 described later. Also in this case, the marker 7 is provided so as to overlap the central portion of the balloon 5.

As shown in FIGS. 1 and 2, the auxiliary balloon 6 is disposed between the curved portion 42 of the reinforcing plate 4 of the band 2 and the balloon 5. The auxiliary balloon 6 is made of a flexible material and is disposed so as to overlap the balloon 5. By injecting air into the auxiliary balloon 6 and the balloon 5, the auxiliary balloon 6 functions as an expansion member that presses the balloon 5 and applies a compression force.
The material for forming the auxiliary balloon 6 may be any material that allows the operator to visually recognize the puncture site 100, and the same material as that for forming the balloon 5 can be employed. The auxiliary balloon 6 is preferably substantially transparent. Thus, the surgeon can visually confirm the puncture site 100 of the patient's wrist H through the band 2, the reinforcing plate 4, the auxiliary balloon 6 and the balloon 5, and can easily align the marker 7 with the puncture site 100. it can.

As shown in FIG. 2, the auxiliary balloon 6 is formed so that the width of the band 2 in the longitudinal direction is smaller than that of the balloon 5, so that the auxiliary balloon 6 includes the curved portion 42 of the reinforcing plate 4 and the balloon 5. The balloon 5 is pressed locally by being disposed between the two. Thereby, the direction of the pressing force F from the balloon 5 to the puncture site 100 can be inclined more reliably.
Then, the auxiliary balloon 6 contacts the curved portion 42 of the curved plate 4 or the right side portion in FIG. As a result, the direction of the force that the auxiliary balloon 6 receives from the curved plate 4, in other words, the normal direction of the reinforcing plate 4 where the auxiliary balloon 6 contacts via the band 2 is the center G of the wrist H. It will incline in the direction that heads. As a result, the direction of the pressing force f and the pressing force F can be tilted more reliably.

  As shown in FIG. 2, a part of the balloon 5 and a part of the auxiliary balloon 6 are joined together by a method such as fusion or adhesion. A communication portion (opening portion) 12 that connects the inside of the balloon 5 and the inside of the auxiliary balloon 6 is formed at the joint portion. As a result, when fluid (air) is injected into the balloon 5 as described above, a part of the injected fluid flows into the auxiliary balloon 6 via the communication portion 12, and the auxiliary balloon is expanded as the balloon 5 is expanded. 6 expands. Thereby, the balloon 5 and the auxiliary balloon 6 can be expanded by one air injection operation, and the operability of air injection is excellent.

As shown in FIG. 2, the auxiliary balloon 6 is connected to the inner side of the band 2 on the same side (right side position in FIG. 2) as the connecting portion 11 of the balloon 5 through the fixing portion 13. . As a result, the auxiliary balloon 6 is inclined more easily and reliably, so that the pressing force f against the balloon 5 acts in a direction in which the balloon 5 is inclined (a direction in which the balloon 5 is directed substantially toward the center G of the wrist H). It becomes easy and a better hemostatic effect can be obtained.
Note that the pressing member that presses the balloon 5 is not limited to the auxiliary balloon 6, for example, a pad formed of a sponge-like substance, an elastic material, an aggregate of fibers such as cotton, or a combination thereof. Such a member may be used.

Next, the air (fluid) injection part 50 shown in FIG. 1 will be described.
The injection unit 50 includes a tube 51 and a bag body 52. The tube 51 is a flexible tube, and one end 51 </ b> A of the tube 51 is connected to the connection portion 5 </ b> R of the balloon 5. The other end portion 51 </ b> B of the tube 51 is connected to the connection portion 52 </ b> A of the bag body 52. The bag body 52 has a connection portion 52A at one end and a connector 60 at the other end. The injection part 50 forms an injection path from the connector 60 to the balloon 5.

FIG. 3 shows a cross-sectional shape example of the connector 60 and a configuration example of the pressure reducing member 150. As shown in FIG. 3, the connector 60 has a tapered inner peripheral surface portion 61. For example, a fluid passage (air passage) 77 is formed in the inner peripheral surface portion 61 of the connector 60. Has been. A valve element 70 capable of opening and closing the fluid passage 77 is disposed in the fluid passage 77. The valve body 70 is made of a flexible material, and normally has a structure that prevents fluid (air) from passing through by closing the fluid passage 77 in the inner peripheral surface portion 61.
Further, the valve body 70 is inserted into the connector 60 by inserting the first projecting portion 202 of the syringe 200 or the second projecting portion 152 of the pressure reducing member 150 as a fluid supply member to be described next shown in FIG. As shown in FIG. 3, it is pushed in the D direction. As a result, the valve body 70 is pushed in the D direction to open the fluid passage 77, thereby allowing fluid (air) to pass through the fluid passage 77 in the inner peripheral surface portion 61 of the connector 60. .
However, in FIG. 3, the valve body 70 is disposed on the inner peripheral surface portion 61, but the present invention is not limited thereto, and the arrangement position of the valve body 70 may be another part.

  The 2nd protrusion part 152 of the pressure reduction member 150 is the same shape as the 1st protrusion part 204 of the syringe 200 as a fluid supply member. In the connector 60, the inner peripheral surface of the connecting portion into which the first projecting portion 204 and the second projecting portion 152 are inserted has a taper angle similar to the taper angle of the outer peripheral surface of the first projecting portion 204 and the second projecting portion 152. It is preferable to constitute so that. Thereby, the surgeon can liquid-tightly connect the inner peripheral surface of the connector 60 and the outer peripheral surfaces of the first projecting portion 204 and the second projecting portion 152. Further, by making the first projecting portion 204 and the second projecting portion 152 the same shape and different from the shape of a general syringe, the surgeon can perform another medical instrument (for example, the first projecting portion) during the procedure. A syringe having a protruding portion having a shape different from that of 204 in the fluid injection portion 202 is not erroneously inserted into the connector 60 of the hemostatic device.

  The first protrusion 204 of the syringe 200 is provided at the tip of the fluid injection part 202 of the syringe 200. For example, the first protrusion 204 is processed to form the first protrusion 204 in the fluid injection part 202 of the syringe 200, or the cap has the first protrusion 204 at the tip of the fluid injection part 202 of the syringe 200. It may be formed by attaching or the like. The first protrusion 204 is preferably formed by attaching a cap having the first protrusion 204 to the tip of the fluid injection part 202 of the syringe 200. By setting it as such a structure, the 1st protrusion part 204 can be formed in the syringe 200 by simple operation.

  The second protrusion 152 of the pressure reduction member 150 is provided so as to communicate with the storage chamber 150 of the pressure reduction member 150 and has the same shape as the first protrusion 204. The second protrusion 152 of the pressure reducing member 150 may be processed so that the tip opening of the pressure reducing member 150 forms the second protrusion 152, or a cap having the second protrusion 152 is attached. You may form by doing.

Next, with reference to FIG. 1, the structural example of the syringe 200 which is a fluid supply member is demonstrated.
A syringe 200 shown in FIG. 1 is a fluid supply member that supplies air into the balloon 5 and the auxiliary balloon 6. The syringe 200 includes a cylindrical main body portion 201, a fluid injection portion 202 having a first projecting portion 204, and a pusher 203. A fluid injection part 202 having a first protrusion 204 is provided at one end of the main body 210. A pusher 203 is inserted into the main body 201. The first protruding portion 204 can be connected to the bag body 52 by being inserted into the connector 60. As described above, when the first protrusion 204 is inserted into the connector 60, the valve body 70 shown in FIG. 3 is pushed in the D direction. As a result, the valve body 70 is pushed in the D direction to open the fluid passage 77, thereby allowing fluid (air) to pass through the inner peripheral surface portion 61 of the connector 60.
Then, when the surgeon pushes the pusher 203, the air (fluid) in the main body portion 201 flows from the main body portion 201 to the first projecting portion 204 and the inner peripheral surface of the connector 60 shown in FIG. It can be injected into the balloon 5 and the auxiliary balloon 6 through the fluid passage 77 of the portion 61 and through the bag body 52 and the tube 51.

Next, a structural example of the pressure reducing member 150 will be described with reference to FIGS. 1, 3, and 4.
FIG. 4 shows an example of use of the pressure reducing member 150.
When the band 2 of the above-described air-injection type hemostatic device 1 for compression shown in FIG. 1 is used to stop the puncture site 100 shown in FIG. 2, the hole of the blood vessel is blocked with blood over time. Therefore, if it is compressed with the initial set compression force by the hemostatic device, blood flow in the blood vessels may be inhibited, and numbness or pain may occur.
For this reason, the surgeon stops the puncture site 100 over several hours while manually performing an operation of periodically reducing the compression force by the hemostatic instrument, that is, an operation of decompressing the balloon. The pressure reducing member 150 shown in FIGS. 1 and 3 is used to stop hemostasis over several hours by periodically reducing the pressing force of the hemostatic device 1 against the puncture site 100 by an operator's operation.

As shown in FIG. 3, the pressure reducing member 150 includes a main body container 151, a second protrusion 152 for attachment, and a partition member 160. The pressure reducing member 150 can also be called a compression force reducing member. The pressure reducing member 150 can be made of the same material as the syringe 200, and is made of, for example, plastic or glass. The main body container 151 has a cylindrical portion 153, a bottom 154, and an opening 155. The second protrusion 152 has a circular cross section, has a tapered shape, and has a tapered cylindrical portion 152A. As shown in FIGS. 3 to 4A, the cylindrical portion 152A is detachably fitted in the inner peripheral surface portion 61 of the connector 60. In addition, it is preferable that this 2nd protrusion part 152 is the same shape and the same magnitude | size as the 1st protrusion part 204 of the syringe 200 shown in FIG. Specifically, the cylindrical portion 152A of the second protruding portion 152 is preferably the same shape and the same size as the tapered cylindrical portion 204A of the first protruding portion 204 of the syringe shown in FIG.
As shown in FIG. 4A, when the cylindrical portion 152A of the second projecting portion 152 of the pressure reducing member 150 fits into the inner peripheral surface portion 61 of the connector 60, the cylindrical portion 152A of the second projecting portion 152 is 3 to 4A, the valve body 70 is pushed in the D direction. Thereby, the valve body 70 is pushed and opened in the D direction, so that the fluid passage 77 in the inner peripheral surface portion 61 of the connector 60 can be opened to allow air to pass therethrough.

As shown in FIGS. 3 and 4A, the pressure reducing member 150 has, for example, two partition members 160. These partition members 160 are arranged at intervals in the cylindrical portion 153. Each partition member 160 is a plate-like member, and has an operation head 161 and a stopper 162. Each partition member 160 is disposed to divide the space in the cylindrical portion 153 into a plurality of first storage chambers SP1 and second storage chambers SP2. Each partition member 160 is slidable in the T direction. The T direction is a direction orthogonal to the longitudinal direction of the pressure reducing member 150 and is also orthogonal to the D direction. Storage capacity of KakuOsamu volume chamber, for example, about 0.5 mL, capacity of the entire yield vessel chamber is, for example, about 1.0～2.0ML, not particularly limited. For example, in FIG. 3, the storage capacity of the fluid (air) in the first storage chamber SP1 and the second storage chamber SP2 is, for example, about 0.5 mL.

As shown in FIG. 3, in a state where each partition member 160 is inserted into the cylindrical portion 153, the space in the cylindrical portion 153 is divided into a plurality of first storage chambers SP1 and second storage chambers SP2. The operator can open the inside of the cylindrical portion 153 by grasping the operation head 161 of the partition member 160 with a finger, sliding in the T direction, and pulling it out.
As shown in FIGS. 4A to 4B, when the upper partition member 160 is pulled out in the T direction, the balloon 5 and the auxiliary balloon 6 are connected to the inner peripheral surface portion 61 of the connector 60, the bag body 52, and the like. The tube 51 leads to the first storage chamber SP1. Furthermore, when the lower partition member 160 is pulled out in the T direction, the balloon 5 and the auxiliary balloon 6 pass through the first inner chamber SP1 and the second chamber through the inner peripheral surface portion 61 of the connector 60, the bag body 52, and the tube 51. Connects to both SP2. As a result, the partition member 160 is an operation for stepping out a certain amount of air in the balloon 5 and the auxiliary balloon 6 over time by simply grasping the operation head 161 with a finger and sliding in the T direction. Can be easily performed.

Next, the usage example of the hemostatic device 1 mentioned above is demonstrated.
The band 2 of the hemostatic device 1 shown in FIG. 1 is attached to the patient's wrist H, for example, as shown in FIG. 2, but air is not injected into the balloon 5 and the auxiliary balloon 6 before the attachment. The balloon 5 and the auxiliary balloon 6 are not expanded.
When the band 2 shown in FIG. 1 is attached to the wrist H as shown in FIG. 2, the puncture member 100 for the normal artery is in a position offset to the thumb side inside the wrist H (the side where the tendon is located). is there. An introducer sheath is placed at the puncture site 100. The band 2 is wound around the wrist H in a state where the introducer sheath is indwelled, and the balloon 5 is aligned so that the marker 7 provided on the balloon 5 overlaps the puncture site 100. Then, the vicinity of both ends of the belt body 2 is fixed by the hook-and-loop fastener 3.

After attaching the hemostatic device 1 shown in FIG. 1 to the wrist H, the operator inserts the first projecting portion 204 of the syringe 200 into the connector 60 of the injection portion 50 shown in FIG. When the first projecting portion 204 of the syringe 200 is pushed into the inner peripheral surface portion 61 of the connector 60, the first projecting portion 204 of the syringe 200 pushes the valve body 70 in the connector 60 in the D direction to open the valve body 70.
Then, when the surgeon pushes the pusher 203 of the syringe 200, the air (fluid) in the main body portion 201 is changed into the fluid (air) passage 77 in the inner peripheral surface portion 61 of the connector 60 and the bag body 52. And injecting into the balloon 5 and the auxiliary balloon 6 through the tube 51. Thereby, the balloon 5 and the auxiliary balloon 6 are expanded with a predetermined air pressure. During the air injection, the balloon 5 and the auxiliary balloon 6 can adjust the degree of expansion, that is, the compression force on the puncture site 100, depending on the patient's case, depending on the amount of air injected.
Thus, when the balloon 5 and the auxiliary balloon 6 are expanded, the first protrusion 204 of the syringe 200 is removed from the connector 60. Thereby, the valve body 70 in the connector 60 shown in FIG. 3 closes the inner peripheral surface portion 61 so that air does not leak. That is, when the first protrusion 204 of the syringe 200 is removed, the valve body 70 shown in FIG. 3 is closed, so that the air in the balloon 5 and the auxiliary balloon 6 does not leak out from the connector 60. Then, the introducer sheath is removed from the puncture site 100.

  As shown in FIG. 2, the balloon 5 and the auxiliary balloon 6 can maintain the expanded state, and can maintain the compressed state to the puncture site 100. In this expanded state, the balloon 5 locally presses the puncture site 100 and the periphery thereof, and the reinforcement plate 4 is separated from the surface of the wrist H by the expansion of the balloon 5 and the auxiliary balloon 6 and contacts the wrist H. It becomes difficult to do. For this reason, since the puncture site 100 and its periphery are concentrated and receive a compression force, the hemostasis effect is high, and it is possible to avoid pressing other blood vessels, nerves, and the like that do not require hemostasis. For this reason, numbness of the hand, poor blood circulation, and the like are prevented.

  By the way, when the band 2 of the above-described air-injection type hemostatic device 1 for compression shown in FIG. 1 is used, the hole of the blood vessel of the puncture site 100 is blocked with a thrombus as time elapses. Therefore, unless the pressure on the blood vessels by the balloon 5 and the auxiliary balloon 6 is reduced with the passage of time, the blood flow of the blood vessels may be inhibited, and limbs may become numb and painful. In order to avoid such inconvenience, the operator spends several hours while manually performing the operation of periodically reducing the compression force by the hemostatic device 1, that is, the operation of reducing the air pressure of the balloon 5 and the auxiliary balloon 6. To stop bleeding. That is, the surgeon stops hemostasis over several hours by periodically reducing the pressing force by the hemostatic device 1 using the pressure reducing member 150 shown in FIGS. 1 and 3.

  In order to connect the pressure reducing member 150 shown in FIG. 1 to the connector 60, the second protrusion 152 for mounting the pressure reducing member 150 is connected to the inner peripheral surface of the connector 60 as shown in FIGS. 3 to 4A. It is inserted into the portion 61 and connected. As described above, when the mounting second protrusion 152 is connected to the inner peripheral surface portion 61 of the connector 60, the valve body 70 is pushed as shown in FIG. Air passes through a fluid (air) passage 77 in 61.

Therefore, when a certain time has passed since the operator attached the pressure reducing member 150, the operator operates the head for operating the upper partition member 160 as shown in FIGS. 4 (A) to 4 (B). 161 is grasped and the upper partition member 160 is pulled out in the T direction. When the upper partition member 160 is pulled out in the T direction, as shown in FIG. 4B, the stopper 162 hits the inner wall portion of the first storage chamber SP1, so that the upper partition member 160 is not pulled out. No. For this reason, it can prevent that a partition member slips out and air leaks out from the inside of the first storage chamber SP1.
Thereby, the first storage chamber SP1 of the pressure reducing member 150 is connected to the balloon 5 and the auxiliary balloon via the fluid (air) passage 77, the bag body 52, and the tube 51 in the inner peripheral surface portion 61 of the connector 60. 6 is connected to the inside. Accordingly, the air in the balloon 5 and the auxiliary balloon 6 enters only the capacity of the first storage chamber SP1. That is, a part of the air in the balloon 5 and the auxiliary balloon 6 is extracted into the first storage chamber SP1, so that the compression force by the balloon 5 and the auxiliary balloon 6 can be reduced.

When the time further elapses, as shown in FIG. 4B, the operator grasps the head 161 for operation of the next lower partition member 160 and pulls out the lower partition member 160 in the T direction. When the lower partition member 160 is pulled out in the T direction, the stopper 162 abuts against the inner wall portion of the second storage chamber SP1, so that the lower partition member 160 does not come out. For this reason, it can prevent that the partition member slips out and the air in 1st storage chamber SP1 and 2nd storage chamber SP2 leaks outside.
Accordingly, the second storage chamber SP2 of the pressure reducing member 150 is connected to the inside of the balloon 5 and the auxiliary balloon 6 via the first storage chamber SP1, the connector 60, the bag body 52, and the tube 51. Therefore, the air in the balloon 5 and the auxiliary balloon 6 further enters the amount corresponding to the accommodation capacity of the second accommodation chamber SP1. That is, since the air in the balloon 5 and the auxiliary balloon 6 further enters the second storage chamber SP2, the compression force by the balloon 5 and the auxiliary balloon 6 can be further reduced.

In this way, by connecting the pressure reducing member 150 to the connector 60 instead of the syringe 200, a certain amount of air is supplied from the balloon 5 and the auxiliary balloon 6 into the first accommodation chamber SP1 and the second accommodation chamber SP2 in a certain space. Therefore, the pressure of the compression force of the balloon 5 and the auxiliary balloon 6 can be reduced.
Since the first storage chamber SP1 and the second storage chamber SP2 of the pressure reducing member 150 have a constant storage volume that does not fluctuate due to the compression force for hemostasis at the time of connection, it is possible to push the movable storage chamber SP1. Compared with the case where a syringe having a child is used, the pressure reduction amount does not vary. When performing hemostasis of the puncture site 100 using the hemostatic device 1, the operator reduces the compression force on the puncture site 100 for several hours while periodically reducing the compression force in the hemostatic device 1 over several hours. There is no risk of sudden pressure reduction or re-bleeding, and hemostasis of the puncture site 100 can be performed while safely and easily reducing pressure.

(Second Embodiment)
Next, a second embodiment of the present invention will be described with reference to FIG.
FIG. 5 shows a second embodiment of the present invention. FIG. 5 shows a pressure reducing member 250 having a structure different from that of the pressure reducing member 150 shown in FIG. 4, but the same portions are denoted by the same reference numerals and description thereof is omitted.
As shown in FIG. 5, the pressure reducing member 250 includes a main body container 251, a second protrusion 152 for attachment, and three partition members 160. Since the three partition members 160 are provided, the cylindrical member 163 includes a first storage chamber SP1, a second storage chamber SP2, and a third storage chamber SP3. Thereby, in the pressure reduction member 250, the upper partition member 160, the middle partition member 160, and the lower partition lower portion 160 are sequentially slid in the T direction every certain time, whereby the balloon 5 of the hemostasis device 1 is obtained. In addition, a certain amount of air can be safely removed little by little from the auxiliary balloon 6 into the first accommodation chamber SP1, the second accommodation chamber SP2, and the third accommodation chamber SP3 in a certain space.

  Therefore, the first storage chamber SP1, the second storage chamber SP2, and the third storage chamber SP3 of the pressure reducing member 250 have a fixed storage volume that does not change the storage volume due to the compression force for hemostasis at the time of connection. Therefore, the pressure reduction amount does not fluctuate compared to the case where a syringe is used. When performing hemostasis of the puncture site 100 using the hemostatic device 1, the operator reduces the compression force on the puncture site 100 for several hours while periodically reducing the compression force in the hemostatic device 1 over several hours. The puncture site 100 can be hemostatically while reducing the compression force safely and easily without the risk of sudden pressure reduction or re-bleeding.

(Third embodiment)
Next, a third embodiment of the present invention will be described with reference to FIG.
FIG. 6 shows a third embodiment of the present invention. FIG. 6 shows a pressure reducing member 250 having the same structure as the pressure reducing member 250 shown in FIG. In FIG. 6, the connector 360 of the bag body 52 is different from the connector 60 shown in FIG. 3, and includes a first connector portion 361 and a second connector portion 362.

Since the first connector portion 361 shown in FIG. 6 has the same structure as the connector 60 shown in FIG. 3, the same reference numerals are given and description thereof is omitted.
The second connector portion 362 shown in FIG. 6 has an inner peripheral surface portion 461, and the first protruding portion 204 of the syringe 200 as the fluid supply member shown in FIG. 6 is inserted into the inner peripheral surface portion 461. It has become. When the first protrusion 204 of the syringe 200 is inserted into the inner peripheral surface portion 461, the valve body 70 opens in the D direction, so that air passes through the fluid (air) passage 477 in the inner peripheral surface portion 461. It is like that.
Thus, since the connector 360 of the bag body 52 can insert and hold | maintain the pressure reduction member 250 and the syringe 200 simultaneously using the 1st connector part 361 and the 2nd connector part 362, the syringe 200 and pressure Since the replacement work of the reducing member 350 is not necessary, the operation for applying the compression force and the stepwise reduction treatment of the compression force become easier.
Note that the pressure reducing member 250 and the syringe 200 may be fixedly connected to each connector.

As described above, the hemostatic device 1 according to the embodiment of the present invention is connected to the band 2 that is wound around and fixed to the site of the limb that is to be stopped, and is expanded by injecting fluid. A balloon 5 (auxiliary balloon 6) as an expansion member that applies a compression force for hemostasis of the region to the region, and a pressure reduction member 150 that draws a certain amount of fluid in the expansion member when reducing the compression force of the expansion member. And a syringe 200 as an example of a fluid supply member. The pressure reducing member 150 partitions the main body container 151 having a storage chamber (for example, the first storage chamber SP1 and the second storage chamber SP2) for storing a certain amount of fluid, the expansion member 5 (6), and the storage chamber. And a partition member 160 for reducing the compression force of the expansion member by connecting the expansion member and the storage chamber by being moved and guiding the fluid in the expansion member to the storage chamber.
Thus, when a surgeon uses a hemostatic instrument to stop a site to be stopped, the operator can periodically reduce the compression force by removing a certain amount of fluid from the expansion member to the accommodation chamber side. Can be done over time. For this reason, reduction of the compression force with respect to the site | part which should be hemostatic can be performed over time. Therefore, there is no risk of sudden pressure reduction or rebleeding, and it is possible to safely and easily reduce the compression force when compressing a portion of the limb that is to be hemostatic.

The pressure reducing member 150 includes a plurality of storage chambers (for example, the first storage chamber SP1 and the second storage chamber SP2), a balloon 5 (auxiliary balloon 6) as an expansion member, and a storage chamber closest to the expansion member. It has the partition member 160 for partitioning, and the partition member 160 for partitioning between each storage chamber.
Thereby, since the pressure reduction member has a plurality of storage chambers, a partition member for partitioning between the expansion member and the storage chamber closest to the expansion member, and between the storage chambers By sequentially moving the partition members for partitioning with time, it is possible to easily reduce the compression force of the part of the limb that is to be hemostatically little by little.

The pressure reducing member 150 has a second projecting portion 152 formed to project from the accommodation chamber. The connector 60 is connected to the expansion member side, and the second projecting portion of the pressure reducing member is provided in the connector 60. 152 is detachably inserted and connected.
Accordingly, the pressure reducing member can be connected to the expansion member only by fitting the second projecting portion of the pressure reducing member into the connector, and the mounting of the pressure reducing member can be facilitated. Therefore, the surgeon can easily reduce the compression force applied to the site to be hemostatic by the expansion member.

As shown in FIG. 4, the connector 60 has a valve body 70 that closes the fluid passage. When the protrusion 152 of the pressure reducing member is inserted into the connector 60 and connected, The valve body 70 is pushed by the two projecting portions 152 to open the fluid passage 77 in the connector 60.
As a result, the fluid passage in the connector can be opened simply by inserting and connecting the second protrusion into the connector. If the partition member is moved, the fluid in the expansion member is reduced in pressure through the connector. It can be discharged to the member side through a fluid passage in the connector.

As shown in FIG. 6, the connector 360 is fixedly connected to the second projecting portion 152 of the pressure reducing member 250, or detachably connected as shown in the figure, and an expansion member. The first protrusion 204 of the syringe 200 as a fluid supply member that injects fluid to expand the expansion member is fixedly connected, or has a second connector portion 362 that is detachably connected as shown in the figure.
Thereby, since the pressure reducing member 250 and the syringe 200 can be inserted and held at the same time, it is not necessary to replace the fluid supply member and the pressure reducing member, so that the pressure reducing treatment can be easily performed.

When the partition member 160 is pulled out to the outside of the pressure reducing member, the partition member 160 releases the state of partitioning between the expansion member and the storage chamber or the state of partitioning between the storage chambers.
Thereby, the operator can release the state of partitioning between the expansion member and the storage chamber, or the state of partitioning between the storage chambers, simply by pulling the partition member out of the pressure reducing member, The compression force reduction treatment can be easily performed.

(Fourth embodiment)
FIG. 7 shows a fourth embodiment of the present invention.
FIG. 7A is an example in which no partition member is provided in another example of the pressure reducing member 150. FIG. 7B shows another example of the syringe 200, and an attachment member 291 as an attachment is detachably attached to the distal end portion 290 of the syringe 200. Similarly, FIG. 7C shows a pressure reducing member 150, and an attachment member 291 having the same structure is detachably attached to the distal end portion 150 </ b> S of the pressure reducing member 150. As described above, the common attachment member 291 is attached to the distal end portion 290 of the syringe 200 and the distal end portion 150S of the pressure reducing member 150, and the attachment member 291 is used to connect to the inside of the connector 60 of the bag body 52. it can.
Thereby, since the front-end | tip part 290 of the syringe 200 and the front-end | tip part 150S of the pressure reduction member 150 can be connected to the connector 60 of the bag body 52 using the special attachment member 291, another instrument is accidentally connected to the connector 60. Incorrect connection can be prevented. In addition, fluid leakage can be prevented by the corners 292 of the attachment member 291 coming into contact with the interior 60 </ b> R of the connector 60. Further, the distal end portion 293 of the attachment member 291 is inserted to the back of the valve body 70 so that the valve body 70 is opened.
Other configurations are the same as those of the first embodiment.

  The valve body 70 of the present invention is not limited to the first to fourth embodiments described above, and is constituted by an opening / closing member that opens and closes a fluid passage in the connector and a spring member such as metal. It may be. In this case, the valve element controls the opening and closing of the fluid passage in the connector by using a restoring force generated when the spring member is compressed. For example, the valve body normally has a structure in which a fluid passage in the connector is closed and fluid (air) is not passed. Then, when the surgeon inserts the protruding portion (first protruding portion or second protruding portion) of the fluid supply member or the pressure reducing member into the connector, the spring member is compressed and the opening / closing member moves, The fluid passage is configured to open. Further, when the valve body pulls out the protruding portion (first protruding portion or second protruding portion) of the fluid supply member or pressure reducing member from the inside of the connector, the opening / closing member moves by the restoring force of the spring member, and the fluid in the connector The flow path is closed.

The present invention is not limited to the above embodiment, and various modifications can be made without departing from the scope of the claims.
A part of each configuration of the above embodiment can be omitted, or can be arbitrarily combined so as to be different from the above.
For example, the fluid injected into the balloon 5 and the auxiliary balloon 6 is not limited to air, but may be nitrogen, other gases, or liquids, for example.
