Description

Medical tourniquet

  The present invention relates to a medical hemostatic device used for compressing an injected site to stop bleeding after injection into a blood vessel such as blood collection or infusion.

  Conventionally, for blood sampling, intravenous injection, infusion, blood transfusion, artificial dialysis, etc. in medical practice, an injection needle or catheter is used for a predetermined puncture site with blood vessels on the skin of the examinee or patient (venous lines or peripherals such as arms) When puncturing the part where the arterial line is), after removing the injection needle, it is necessary to cover the needle puncture mark (puncture hole) of the puncture part with alcoholic cotton and press it with a thumb etc. to stop bleeding. . In this case, the compression time is usually required to be about 5 minutes. At this time, a hemostatic pad in which a cotton pad is attached to the adhesive surface of the adhesive tape may be used instead of alcoholic cotton. In addition, although the hemostasis pad protects the needle puncture mark, it does not compress the needle puncture mark necessary for hemostasis, and it is necessary to press the cotton pad part with a thumb etc. for a certain period of time. A hemostatic band is also wound around a puncture part such as an arm, and the cotton pad portion of the hemostatic pad is fixed and pressed by the hemostatic band. In addition, since the hemostatic band is expensive, a compression type hemostatic pad in which a needle prick compression function is added to the cotton pad of the hemostatic pad has been proposed.

  Here, as an invention in which the conventional hemostatic pad and the hemostatic band are improved, for example, Patent Document 1 and Patent Document 2 describe an invention in which the hemostatic pad is improved, and Patent Document 3 discloses an invention in which the hemostatic belt is improved. Is described. That is, the adhesive material for hemostasis of Patent Document 1 is provided with an adhesive layer on one surface of a base material, and a pad is fixed on the adhesive layer, and the pad can be formed when a needle or the like is stabbed. It has a size that covers both the puncture hole of the blood vessel and the puncture hole on the skin surface, and has a thickness and compression hardness that can press both the puncture holes to an appropriate strength (see summary). . In addition, the adhesive bandage for hemostasis of Patent Document 2 includes an adhesive layer provided on one surface of a base material, and a gas or liquid that is fixed to a substantially central position on one surface of the base material and elastically deformable in a non-directional direction inside. , A bag-like member containing an elastic body made of a gel-like body, and a release material that is detachably attached to the adhesive layer of the base material. While being in contact with the hemostatic site, the adhesive layer is adhered to the skin surface of the human body and is pressed toward the skin by a stretchable or non-stretchable pressing member (see summary). Further, the hemostatic device of Patent Document 3 includes a hemostatic stay main body formed in an M-shape having a flat pressing portion at the center, with both sides of the flat pressing portion bent into a mountain shape and having a bending and stretching force, and the hemostatic device. A fastening band is connected to both outer ends of the stay main body directly or to a bent connection portion connected to both outer ends (see summary).

  However, the inventions described in Patent Document 1 and Patent Document 2 both fix the adhesive layer of the base material around the puncture hole of the skin and fix the pad to the skin only by the tension or tensile force of the base material. Because it is configured to press the puncture part by pressing it against the puncture part, the compression force on the puncture part depends only on the tension or tensile force of the base material, and there is a possibility that sufficient compression force cannot be obtained There is. In addition, since the pressing force on the puncture part depends only on the base material, the base material stretches due to plastic deformation over time, and the tensile force or tensile force of the base material decreases or disappears. May not be maintained for the required time. Here, in cases where the hemostasis subject has low hemostasis ability, or in the case of a hemostasis subject who always performs puncture with an injection needle, such as a renal dialysis patient, hemostasis is more difficult than usual. It is necessary to continue pressing the puncture hole portion with a stronger compression force for a longer time. On the other hand, in the hemostatic device of Patent Document 3, a gauze is interposed in the puncture portion of the skin, and then the flat pressing portion of the hemostatic stay main body is applied to the gauze, and the tightening band wound around the hemostatic stay main body around the patient's arm or the like By tightly connecting both ends of the pin, it is possible to obtain a stronger pressing force than in the case of Patent Document 1 and Patent Document 2 because the pressure is applied to the puncture portion, but the overall configuration is large.

  Hereinafter, modes for carrying out the present invention (hereinafter referred to as embodiments) will be described. Throughout each embodiment, the same members, elements, or parts are denoted by the same reference numerals, and the description thereof is omitted.

Embodiment 1
As shown in FIG. 1, the medical hemostatic device according to Embodiment 1 includes a base body 10 as a fixed portion and a pressing body 20 as a movable portion, and the base body 10 and the pressing body 20 are configured as an integrated structure. This is a one-piece structure in which the body 20 is tilted with respect to the base body 10 to be superposed. That is, the medical hemostatic device of Embodiment 1 is obtained by integrally molding the base body 10 and the pressing body 20 with a predetermined material. In addition, from the viewpoint of manufacturing cost and the like, the medical hemostatic device having such an integrated structure is preferably formed by integrally molding the base body 10 and the pressing body 20 with a synthetic resin material by using an injection molding technique. It is also possible to integrally form by using other molding methods.

[Substrate]
Specifically, the base body 10 includes a base portion 11 having an opening 15, and a protrusion 12 and a locking portion 13 that are integrally formed with the base portion 11. The base 11 has a rectangular annular ring plate shape, and a rectangular opening 15 is formed on the inner periphery thereof. Specifically, the band plate-like portions on both sides in the length direction of the base 11 (both left and right sides in FIG. 2 (a)) are respectively flat plate shapes having a constant thickness, but both sides in the width direction (FIG. 2 (a)). The straight strip-like portions on the upper and lower sides are each tapered in a cross-section that gradually decreases in thickness toward the outer edge side, and the upper surfaces of the portions are inclined surfaces 11a. The protrusion 12 is integrally formed on the outer edge of the inclined surface 11a on one end side in the width direction (the lower side in FIG. 2A) of the two inclined surfaces 11a of the base 11. The protrusions 12 are integrally formed so as to form a pair at both ends in the length direction of the inclined surface 11a of the base 11 (both left and right ends in FIG. 2A). Each protrusion 12 extends linearly by a predetermined length (a length that is a fraction of the length of the base 11) on the inclined surface 11 a of the base 11, and extends upward from the inclined surface 11 a of the base 11. It protrudes by a slight height. The protrusion height of the protrusion 12 is the thickness of the base 11 (the height of the protrusion 11 so that the protrusion 12 protrudes further upward than the maximum height position of the upper surface of the base 11 (that is, the upper surface position of both ends in the length direction of the base 11). In the inclined surface 11a portion, the height is about twice as large as the thickness of the maximum thickness portion on the inner peripheral edge side. The pair of protrusions 12 are formed by hooking a predetermined taking-out tool when a molded product (medical hemostatic device in a product shape) after the medical hemostatic device is integrally formed by injection molding is punched. It is a part used to facilitate the removal of

  The locking portion 13 extends upward (thickness of the base 11) from the inner edge on the one end side in the length direction of the opening 15 of the base 11 (the left inner edge in FIG. 2A) perpendicular to the base 11. It is integrally formed so as to extend (in the vertical direction). Moreover, the latching | locking part 13 consists of the rectangular flat plate-shaped part extended in the whole width direction of the opening 15 of the base 11, and the hook-shaped part integrally formed in the upper end of the said flat plate-shaped part, The said hook-shaped part The lower surface of this is a locking surface 13a.

[Pressing body]
The pressing body 20 includes a connecting portion 21, a support portion 22, a joining portion 23, a pressing portion 24, and a locked portion 25. The pressing body 20 has substantially the same width as the opening 15 of the base 11 (that is, the same width as the locking portion 13), and the connecting portion 21, the support portion 22, the pressing portion 24, and the locked portion 24. It is integrally molded so as to have a bent / curved plate shape shown in FIG. Specifically, the connecting portion 21 constitutes a joint portion between the base body 10 and the pressing body 20, and includes a hinge portion 21a and a bent portion 21b. The hinge portion 21a has a plate shape that slightly protrudes in the length direction of the base portion 11 from a joint portion (a boundary edge with the base portion 11) of the base body 10 and gradually decreases in thickness in the protruding direction. It is tapered. The bent portion 21b has a flat plate shape or a belt plate shape with a constant thickness extending downward from the tip of the hinge portion 21a. The extension dimension of the bent part 21 b (that is, the width dimension of the bent part 21 b itself) is about 4 to 6 times the thickness of the base 11. Further, the bent portion 21b is extended at an angle larger than 90 degrees (in a direction away from the base portion 11) from the tip of the hinge portion 21a so as to form an obtuse angle with the hinge portion 21a. Here, the hinge part 21a constitutes a so-called resin hinge, and the protruding dimension of the hinge part 21a (that is, the width dimension of the hinge part 21a itself) is a small dimension necessary and sufficient for exhibiting the hinge action ( The bent portion 21b is formed with respect to the hinge portion 21a so that the boundary line between the lower surface of the hinge portion 21a and the lower surface of the bent portion 21b is located at substantially the center in the width direction of the hinge portion 21a. It is integrally molded in a bent state.

The support portion 22 is integrated with the bent portion 21b at the tip (lower end) of the bent portion 21b of the connecting portion 21 so as to extend in a direction away from the base portion 11, preferably in a state parallel to the base portion 11. Is formed. The support portion 22 has a rectangular flat plate shape having a length substantially equal to that of the base portion 11 (and a width substantially equal to the opening 15 of the base portion 11), and the user can press his / her fingertip (finger pad portion) during the pressing operation of the pressing body 20. This is the part used to apply the pressing force by pressing the minute). Junction 23, the distal end of the support portion 22 is a flat plate-like or strip-like constant thickness which is integrally molded to be extended in a bent state from the support portion 22 is inclined upward. The extension dimension of the joint part 23 (that is, the width dimension of the joint part 23 itself) is substantially the same as that of the bent part 21b of the connecting part 21, and the joint part 23 is in the open state of the medical hemostatic device of FIG. The upper end position is substantially the same as the upper end position of the connecting portion 21 (that is, the height position of the base portion 11). The pressing portion 24 is integrally formed with the joint portion 23 at the tip (upper end) of the joint portion 23 so as to extend in a curved state in a direction approaching the base portion 11. The pressing portion 24 has a curved plate shape with a substantially U-shaped cross section, and the center portion (the portion closest to the base portion 11) in the bending direction (length direction) exceeds the center in the length direction of the support portion 22. Thus, it is located at a position approaching the base portion 11 (for example, a position extending from the tip of the support portion 22 toward the base portion 11 with a length of about 85 to about 90% of the length of the support portion 22). Further, the distal end of the pressing portion 24 is located on the support portion 22 side by a slight dimension from the joint boundary line between the support portion 22 and the joint portion 23. Accordingly, the distal end position of the pressing portion 24 is disposed on the support portion 22 side by a little dimension from the proximal end position of the pressing portion 24 (joining position between the pressing portion 24 and the joining portion 23), and when viewed from above. In addition, the tip of the pressing portion 24 is disposed at a position displaced slightly toward the support portion 22 from the joint portion 23 by a size. The bent portion 21b, the support portion 22, the joining portion 23, and the pressing portion 24 of the connecting portion 21 constitute a tilting portion having a substantially S-shaped cross section, and the cross section through the hinge portion 21a of the connecting portion 21. A tilting portion that is substantially S-shaped and integrally has a pressing portion 23 on the tip side can be tilted.

  Here, when the pressing body 20 is tilted with respect to the base body 10 and the pressing portion 24 enters the opening 15 of the base portion 11, the portion on the tip side of the center portion of the pressing portion 24 is from the lower surface of the base portion 11. Also, the whole is disposed in a projecting state at a lower position, and is a planar portion that elastically contacts the puncture portion centered on the puncture hole of the human skin, and is a portion that becomes an elastic contact portion. The curvature rate of the pressing portion 24 (and the separation distance from the support portion 22 of the elastic contact portion defined according to the curvature rate) defines the projecting dimension from the base portion 11 of the elastic contact portion. Considering the elastic pressing force on the puncture part of the human skin, which is a major factor (ie, considering that the pressing force required for hemostasis varies depending on the hemostatic subject), the intended hemostatic subject Is set to such a value that a necessary pressing force can be obtained.

  The locked portion 25 is integrally formed on the outer surface near the center in the width direction of the joint portion 23 so as to protrude from the joint portion 23 by a predetermined dimension. The protruding dimension of the locked part 25 is equivalent to the protruding dimension (from the flat part) of the hook-shaped part of the locking part 13 of the base 10. Further, as described above, the length of the locked portion 25 is equal to the length of the locking portion 13. Therefore, when the pressing portion 24 of the pressing body 20 enters the opening 15 of the base body 10 to be used, the entire lower surface of the locked portion 25 is substantially the entire locking surface 13 a of the locking portion 13. It comes into contact and is locked.

[Installation method]
As shown in FIG. 3, the medical hemostatic device of the present embodiment can be stacked with the pressing body 20 tilted with respect to the base 10. Specifically, the medical hemostatic tool tilts the pressing body 20 toward the base body 10 from the open state of FIG. 1 (a state where the pressing body 20 is completely opened with respect to the base body 10 and deployed to the juxtaposed state). Then, as the pressing body 20 is bent upward with respect to the hinge portion 21a of the connecting portion 21, the hinge portion 21a exhibits a resin hinge function, and the bent portion 21b. The support part 22, the joint part 23, the pressing part 24, and the locked part 24 are allowed to tilt upward. Here, the present inventor provides a hinge part for tilting the pressing part at different positions of the pressing body, and also performs a verification test on the hinge operation of the hinge part and the entry operation into the opening of the base part of the pressing part at each position. Went. As a result, as in the present embodiment, the hinge portion 21a has a lateral position (the base portion 11 and the pressing body 20) outside the other end in the length direction of the base portion 11 (the end on the joining position side with the pressing body 20). And a position that is closer to the pressing body 20 than the joining position), and extends in a direction substantially parallel to the base 11, the smoothest hinge operation is exhibited and the pressing portion 24 is The medical hemostatic device of the present embodiment was completed by obtaining the knowledge that it would enter the opening 15 of the base 11 most smoothly. Further, when the hinge portion is provided in this way, the elastic pressing portion of the pressing portion 24 that has entered the opening 15 of the base portion 11 is substantially parallel to the base portion below the base portion (more precisely, the elastic pressing portion is curved). Therefore, when the pressing part 24 is pressed against the skin of the puncture part of the hemostatic subject (as will be described later), the elastic pressing part of the pressing part 24 is arranged so that its tangent line is substantially parallel to the base part. The puncture part can be compressed very efficiently. On the other hand, according to this verification test, when the hinge portion is provided at a position on the base side, for example, at a position overlapping the other end portion in the length direction of the base portion (for example, hinge in a direction orthogonal to the other end in the length direction of the base portion). When the pressing body is tilted using the hinge operation of the hinge portion, the pressing portion is at one end in the longitudinal direction of the opening of the base portion. It has been confirmed that a smooth approaching operation cannot be guaranteed. Therefore, in the medical hemostatic device according to the present invention, the hinge portion for allowing the pressing body to tilt with respect to the base is preferably provided at a side position of the base of the base, and further, on the side of the base of the base. It is preferable to provide in one direction so as to extend in a direction substantially parallel to the base.

  First, the pressing portion 24 and the like come to the first tilt position shown in FIG. 3A, that is, the support portion 22 is at an angular position of 60 degrees (−60 degrees in the clockwise direction) with respect to the base portion 11. The center of the pressing portion 24 comes to a position near the upper surface of the base 11 (a position closest to the opening 15). Further, when the pressing body 20 is further tilted with respect to the base body 10 from this state, the second tilting position shown in FIG. 3B, that is, the support portion 22 has come to an angular position of 45 degrees with respect to the base portion. Sometimes, the central portion of the pressing portion 24 slightly enters the opening 15 of the base portion 11, and the tip of the pressing portion 24 comes to a position slightly above the upper end of the locking portion 13. Further, when the pressing body 20 is further tilted with respect to the base body 10 from this state, the third tilting position shown in FIG. 3C, that is, the support portion 22 is at an angular position of 5 degrees with respect to the base portion. Sometimes, the central portion of the pressing portion 24 and the vicinity of the lower end of the elastic contact portion that is the tip side portion from the central portion completely enter the opening 15 of the base portion 11 and the outer surface of the joint portion 23 is locked. The locked portion 25 comes into contact with the tip of the collar portion of the portion 13 and is slightly above the upper end of the locking portion 13. When the pressing body 20 is further tilted with respect to the base body 10 from this state, the fourth tilting position shown in FIG. 3D, that is, the support portion 22 is at an angular position of 0 degree with respect to the base portion. Sometimes, the pressing portion 24 is in a use state or a pressing state, and the central portion of the pressing portion 24 and the vicinity of the lower end of the elastic contact portion that is the tip side portion from the central portion completely enter the opening 15 of the base portion 11. Further, the locked portion 25 elastically climbs over the locking portion 13 and is hooked by the locking surface 13a of the locking portion 13.

  That is, at this time, the pressing body 20 is completely mounted on the base body 10 and the pressing portion 24 is in a mounting position where it does not separate (unless an external force that is intentionally forced to be removed is applied). Thereby, the pressing body 20 is completely fixed to the base body 10, and the pressing portion 24 cannot be detached upward from the opening 15 of the base portion 11. Further, at this time, the support portion 22 is disposed in a state substantially parallel to the base portion 11. That is, since the width dimension of the bent part 21b of the connecting part 21 and the width dimension of the joint part 23 are set to be substantially the same, the pressing body 20 is completely attached to the base body 10 shown in FIG. In the state, the support portion 22 is in a substantially parallel state with respect to the base portion 11, and the thickness of the entire medical attachment can be made very small, so that the entire configuration can be made compact.

  On the other hand, if it is desired to release the pressing portion 24 from the opening 15 of the base portion 11, the locking portion 13 is pressed outward (in a direction away from the locked portion 24) to be elastically deformed. Then, the locked portion 25 is detached from the locking surface 13a of the locking portion 13, the locked state is released, and the clockwise tilt shown in (a) to (a) of FIG. The pressing part 24 can also be tilted upward and away from the opening 15 of the base 11 (by operation) to return to the open state shown in FIG.

[Production method]
The medical hemostatic device of Embodiment 1 can be integrally molded by an injection molding method using a predetermined synthetic resin material (for example, polypropylene resin). Specifically, a mold having a cavity corresponding to the outer shape thereof is prepared, and a medical hemostatic device having a shape shown in FIG. 1 or the like is integrally formed by injection molding using the mold. At the time of die cutting, a predetermined pulling tool is hooked on the protrusion 12 provided on the base body 10, and the molded product after molding is pulled out (in the width direction of the base 11). Since the medical hemostatic device integrally molded in this way has a flat structure as a whole and a compact configuration, and can be manufactured as a single molded body (one-piece structure), the manufacturing cost can be reduced. Can do.

[Product aspect]
The medical hemostatic device manufactured as described above can be used as a single product (that is, in the state of FIG. 1) as it is, but includes an opening 15 as will be described later with reference to FIG. An adhesive tape T with a pad P is applied and integrally joined so as to cover the entire lower surface of the base 11, or, as will be described later with reference to FIG. 4B, only the lower surface of the base 11 is adhered. A pressure-sensitive adhesive layer G made of an agent may be provided, and a pad P may be attached to the elastic pressing portion of the pressing portion 24 to be integrally joined to produce a product. Or it can also be commercialized by providing only the adhesive layer G on the lower surface of the base 11 in the state of FIG. Alternatively, a plurality of medical hemostats are attached to or attached to a long tape-like sheet material by adhesion or fitting, etc., with an interval in the length direction of the sheet material. In addition, at the time of use, the medical hemostatic device can be detached from the sheet material one by one, and each medical hemostatic device can be used for the compression hemostasis of the puncture part of the hemostatic subject. In this way, a user such as a medical worker can quickly apply the medical hemostatic tool to the puncture portion of the hemostasis target person to perform the compression hemostasis operation, and the workability can be improved. In this case, as shown in FIG. 4 (a) or FIG. 4 (b), the medical material is applied to the sheet material with the adhesive tape T with the pad P or the adhesive layer G provided at the base of the medical hemostatic device. The hemostatic tool is temporarily fixed so as to be detachable, and the adhesive tape T with the pad P or the adhesive layer G remains on the lower surface of the base 11 of the medical hemostatic device detached from the sheet material during use.

[how to use]
In order to stop hemostasis of the puncture hole of the puncture portion of the hemostasis subject using the medical hemostasis device of the present embodiment, first, an adhesive such as an adhesive sheet is attached to the lower surface of the base portion 11 of the base 10. The base 11 can be attached to the skin around the puncture portion of the hemostatic subject. For example, as shown in FIG. 4A, a sheet-like pressure-sensitive adhesive sheet T having a shape and size that integrally covers the entire range including the entire lower surface of the base 11 and the entire opening 15 is adhered to the lower surface of the base 11. Bonded firmly and integrally so as not to be easily detached. At this time, the upper surface of the pressure-sensitive adhesive sheet T to be bonded to the lower surface of the base portion 11 is coated with a pressure-sensitive adhesive or an adhesive only at the bonding portion with the lower surface of the base portion 11, and the other portion is not coated with the pressure-sensitive adhesive or the adhesive. It is preferable. On the other hand, a pressure-sensitive adhesive is applied to the entire bottom surface of the pressure-sensitive adhesive sheet T, and a pad P made of cotton cloth or the like is attached to the central portion of the pressure-sensitive adhesive sheet T by the pressure-sensitive adhesive force to integrally bond them. Keep it. And the base 11 which joined this adhesive sheet T with the pad P is exposed by the outer peripheral part (part outside pad P) of the lower surface of the said adhesive sheet T around the puncture part of the skin of a hemostatic subject. When the base 10 is bonded and integrated with the adhesive, the base 10 cannot be detached unless the external force is applied to the hemostatic subject's skin intentionally, and the base 10 is joined and fixed. A fixed position state or a fixed position state facing the skin is maintained.

  In this way, when the base 11 is fixed to the skin of the hemostasis subject, the base 11 surrounds a certain part of the skin centered on the puncture hole of the puncture portion, and the center position of the opening 15 of the base 11 is the puncture hole. It is desirable to position and fix the base 11 so as to be near the position. In this case, normally, when a health care worker such as a nurse pulls out the injection needle from the puncture part of the hemostatic subject after injection to the hemostatic subject, this is performed because the alcoholic cotton is pressed against the puncture part and pulled out. The medical hemostatic device of the form is such that, after the medical worker removes the spirit cotton from the puncture part against which the alcoholic cotton is pressed, the base 11 of the medical hemostatic tool is quickly applied around the puncture part. Need to be fixed. That is, the user who applies the medical hemostatic device of the present embodiment is basically a medical worker who pulls out the injection needle. At this time, the user basically recognizes the position of the puncture hole through the opening 15 of the base 11 and, if possible, accurately recognizes the position of the puncture hole. 11 is positioned relative to the puncture site. Therefore, as shown in FIG. 4A, when the adhesive sheet T is joined so as to cover the entire opening 15 of the base 11, it is difficult to visually recognize the puncture hole through the opening 15. The base 11 can be positioned by accurately predicting the position of the puncture hole as much as possible by, for example, superimposing the base 11 on the position of the fine cotton that is pressed against the puncture. On the other hand, when using a medical hemostatic device in which an adhesive sheet T with a pad P is joined so as to cover the entire opening 15 of the base portion 11 as shown in FIG. 4A, the base portion 11 is stuck around the puncture portion. In this state, it can be expected that the pad P on the lower surface side of the pressure-sensitive adhesive sheet T abuts on the puncture portion and suppresses bleeding from the puncture hole to some extent.

  Thereafter, the user tilts the pressing body 20 in a juxtaposed state with respect to the base body 10 and causes the pressing portion 24 to enter the opening 15 of the base portion 11. Then, when the pressing portion 24 comes from the first tilt position in FIG. 3A to the second tilt position in FIG. 3B, the elastic pressing portion on the distal end side of the pressing portion 24 opens the opening of the base 11. 15 starts to enter 15 and starts pressing the puncture portion of the hemostatic subject via the adhesive sheet T and the pad P. At this time, in the pressing body 20, the support portion 22 is located at an upper position, and the user presses the upper surface of the support portion 22 to further push the pressing portion 24 into the opening 15 of the base portion 11. be able to. At this time, since the support portion 22 having a large flat plate shape is disposed above the base portion 11, the user can easily press the support portion 22, and the pressing portion 24 is opened to the base portion 11. 15 can be pushed into the interior of the medical device 15 smoothly, and the medical hemostatic device can be mounted smoothly. Then, as a result of the user's pushing operation, the pressing portion 24 moves from the second tilt position in FIG. 3B to the fourth tilt position in FIG. 3D through the third tilt position in FIG. 3C. When it comes, the locked portion 25 is hooked on the locking portion 13, the pressing portion 24 is fixed at the final pressing position, and the puncture portion of the hemostatic subject is scheduled via the adhesive sheet T and the pad P It presses with the pressed force (predetermined pressing force set by the curvature rate etc. of the press part 24). As a result, the elastic pressing portion of the pressing portion 24 has a large pressing area, and with a large elastic pressing force, the peripheral portion centering on the puncture hole of the puncture portion is surely strongly pressed and bleeding from the puncture hole Can be completely suppressed. In the case of the medical hemostatic device as shown in FIG. 4 (a), the pressing portion 24 enters the adhesive sheet T while following the opening of the base portion 11, but in this case, However, since the adhesive sheet T is easily deformed by the pressing force from the pressing portion 24 and allows the pressing portion 24 to enter, the pressing operation by the pressing portion 24 is not hindered.

  On the other hand, as shown in FIG. 4 (b), the medical hemostatic device of the present embodiment forms an adhesive layer G by applying an adhesive only to the lower surface of the base 11 (that is, the opening 15 is completely formed). The opening state may be maintained), and a pad P such as a cotton cloth may be attached only to the pressing surface of the elastic pressing portion of the pressing portion 24 to be integrally joined. In this case, in the open state in which the pressing body 20 is arranged side by side with respect to the base body 10, the user can visually recognize the puncture hole of the puncture portion through the opening 15 of the base portion 11. The base 11 is positioned so that the center position of the opening 15 of the base 11 is aligned with the position of the puncture hole immediately after removing the alcoholic cotton, and the base 11 is quickly pressed around the puncture part to perform the puncture. It can be adhesively fixed at an appropriate position on the skin S around the part. Thereafter, as described above, the user can quickly tilt the pressing portion 24 and press it against the puncture portion as a pressing position, thereby pressing the puncture portion and performing hemostasis. In the case of the medical hemostatic device provided with the adhesive layer G as shown in FIG. 4 (b), when the pressing part 24 enters the opening of the base part 11, there is no adhesive sheet T in the path, Compared to the case of FIG. 4A, the approach of the pressing portion 24 to the opening 15 of the base portion 11 and the pressing operation to the puncture portion are further facilitated.

  4 (a) and 4 (b), since the base 11 is securely fixed around the puncture portion of the skin as the fixation target (specifically, as such, Since the adhesive force by the adhesive on the lower surface of the base portion 11 is set), the base portion 11 is not detached from the skin by the reaction force when the pressing portion 24 presses the puncture portion. In other words, the fixing force of the base 11 to the skin is mainly determined by the area of the lower surface serving as the adhesive area of the base 11 and the adhesive force of the adhesive itself. The adhesive strength of the agent (that is, the type of adhesive) is set to a value at which the base 11 does not separate from the skin due to the reaction force when the puncture portion is pressed by the pressing portion 24. Moreover, in the final use state (final press state) which presses the puncture part with the press part 24, the press part 24 itself is also shown from the (originally big) curvature shown in FIG. 3 with the elastic deformation force. Elastically deforms to a curvature (small after deformation) as shown in 4 (b). At this time, as shown in FIG. 4B, the pressing portion 24 presses the puncture portion centered on the puncture hole H of the skin S through the pad P. In this state, the pressing portion 24 is pressed. A recess D is formed between the surrounding skin S and the lower surface of the base 11 by a pressing force to the human body part B such as an arm of the pressing portion 24, and the pressing portion 24 is disposed in the recess D. Become.

  Or you may use what provided the adhesive layer G in the lower surface of the base 11 of the single medical hemostat (thing of the state shown in FIG. 1). In this case, a normal bandage or non-woven fabric with gauze is affixed to the puncture part of the hemostasis target person, and then the base 11 of the medical hemostatic tool is affixed by the adhesive force of the adhesive layer G, as described above. Then, the pressing part 24 performs compression hemostasis of the puncture part. In this case, the base portion is positioned and applied to the puncture portion (and the gauze adhesive bandage or the non-woven fabric covering the puncture portion) so that the base portion 11 directly adheres to the outer skin of the gauze-adhesive plaster or non-woven fabric. In this way, the base portion 11 directly adheres to the skin, and effectively lifts off the skin due to the pressing of the puncture portion by the pressing portion 24 (and the adverse effect of the pressing operation by the pressing portion 24 thereby). be able to. In addition, even when the base part adheres to the adhesive bandage or nonwoven fabric with gauze, if the adhesive bandage or nonwoven fabric with gauze adheres firmly to the skin, it can prevent the lifting from the skin due to compression of the puncture part by the pressing part 24 it can. In any of these cases, it is desirable that the adhesive bandage or non-woven fabric with gauze is positioned and adhered to the skin so that the center position of the gauze or non-woven fabric matches the position of the puncture hole as much as possible. In this way, when the medical hemostatic tool is positioned, the base 11 is adhered by aligning the center of the opening 15 of the base 11 with the gauze bandage or non-woven gauze on the skin or the center of the non-woven fabric. The possibility that the center position of 15 is aligned with the position of the puncture hole can be increased, and the elastic pressing portion of the pressing portion 24 in the mounted state can surely press the range around the puncture hole of the puncture portion. it can.

  Thereafter, when the hemostasis is completed after a lapse of a certain time, the user or the hemostasis target himself / herself peels off the base 11 from the puncture portion of the hemostasis subject's skin against the adhesive force of the adhesive. Thereby, the pressure to the puncture part by the press part 24 is cancelled | released, and the puncture part of the skin of a hemostatic subject person returns to a normal state. The medical hemostatic device is usually discarded for hygiene reasons after being removed from the skin, but the locking portion 13 of the base 10 is forcibly pressed outward (in the direction away from the pressing portion 24). By releasing the hooked state with the locked portion 25, the pressing body 20 can be brought into the open state shown in FIG.

At the same time, the pair of latching portions 724 are elastically deformed rearward (in a direction away from the abutting latched portion 713 and obliquely downward to the right in FIG. 23A), and the latched portion 713 is latched. When the first guide surface 724a of the portion 724 is completely climbed over (that is, when the lower end of the first guide surface 724a is climbed), the latching portion 724 returns to its shape by the elastic force (shown in FIG. 23). Returning to the original position), the upper surface of the hooked portion 713 is hooked on the hooking surface 724b of the hooking portion 724, and the lower pressing body 720 is locked and fixed to the base 710 in a compressed state.

At this time, both end surfaces in the width direction of the release portion 734 of the upper pressing body 730 move on the second guide surfaces 714c (opposing each other) of the pair of latching portions 714 of the base 710 in a substantially abutting state. Alternatively, it is slid and guided to move downward, and finally (in the compressed state) is disposed on the base end side of the second guide surface 714c of the pair of latching portions 714, and as a result, It assists that the stopping portion 732 is moved and guided by the pair of engaging portions 714 in a positioning state, and smoothes the engaging operation of the engaged portion 732 to the engaging portion 714. Similarly, both end surfaces in the width direction of the release portion 735 of the upper pressing body 730 are substantially in contact with each other on the second guide surfaces 724c (opposing each other) of the pair of latching portions 724 of the lower pressing body 720. It is moved or slid and guided to move downward, and finally (in the compressed state) is disposed on the base end side of the second guide surface 724c of the pair of latching portions 724, and as a result, The latching portion 713 is helped to be guided by the pair of latching portions 724 in a positioned state, and the latching operation of the latched portion 713 to the latching portion 724 is made smooth. That is, when the medical hemostatic device is deformed from the released state to the compressed state, as described above, the width dimension of the release portion 734 is such that the width direction end faces or both end edges of the release portion 734 are the second portions of the hook portion 714. The width dimension is such that it can be moved and guided on the guide surface 714c, that is, the dimension corresponding to the gap dimension between the second guide surfaces 714c of the pair of latching portions 714 of the base 710, and similarly, the release portion The width dimension of 735 is a width dimension such that both ends or both edges of the release portion 713 are moved and guided on the second guide surface 724c of the latching portion 724, that is, a pair of the lower pressing body 720. The dimension corresponding to the gap dimension between the second guide surfaces 724c of the latching portion 724 is set.
Similarly,

[Unlock part]
In the medical hemostatic device of the present embodiment, the release portion 734 of the upper pressing body 730 constitutes a lower lock releasing portion that releases the locked state of the lower pressing body 720 to the base 710, and the release portion 735 includes The upper lock release unit that releases the locked state of the upper pressing body 730 to the base 710 is configured. Specifically, in the compressed state, when the upper pressing body 730 and the base 710 are in the locked state, the hooking portion 714 is elastically deformed backward by the fingernail or the like, and the release unit 734 is moved to the fingernail or the like. The hooked portion 732 is disengaged from the hooking surface 714a of the hooking portion 714, and the lock of the hooked portion 732 by the hooking portion 714 is released. Accordingly, the upper pressing body 730 is turned from the compressed state in which the upper pressing body 730 is overlapped with the base body 710 in FIG. 23 from the rotation biasing force (that is, the upper pressing body 730 is overlapped with the base body 710) of the hinge portion (the hooked portion 713 and the thin portion 733). The elastic urging force that rotates upward to the expanded state shown in FIG. Similarly, in the compressed state, when the lower pressing body 720 and the base 710 are in a locked state, the latching portion 724 is elastically deformed backward by a fingernail or the like, and the release unit 735 is The hooked portion 713 is disengaged from the hooking surface 724a of the hooking portion 724, and the hooked portion 724 is unlocked. Accordingly, the lower pressing body 720 is turned from the compressed state in which the lower pressing body 720 is overlapped with the base body 710 from the compressed state in which the lower end pressing body 720 is overlapped with the base body 710 in FIG. The elastic urging force that rotates downward to the expanded state shown in FIG.

[Hemostatic pad]
On the lower surface of the base 721 of the lower pressing body 720, a pad 741 made of a cotton cloth or the like is adhered and integrally joined with an adhesive or an adhesive. The pad 741 has a rectangular pad shape slightly smaller than the lower surface of the base 721.

[Production method]
The medical hemostatic device of the present embodiment is preferably integrally molded into the shape of the expanded state shown in FIGS. 22 and 23 by injection molding a predetermined synthetic resin such as polypropylene resin. Specifically, the medical hemostatic device of the eighth embodiment is prepared with a mold having a cavity corresponding to its outer shape, and the shape shown in FIGS. 22 to 25 is obtained by injection molding using the mold. A medical hemostatic device is integrally molded. Here, in the state (non-compressed state) after manufacture and before use of the medical hemostatic device, the medical hemostatic device includes a base 710, a lower pressing body 720, and an upper pressing body 730 that are connected portions thereof. The hinge portions (thin wall portion 712 and thin wall portion 722 as well as the hooked portion 713 and thin wall portion 733) are in an open state where they are separated from each other and opened due to the hinge effect. In this unfolded state, the hinge portion by the thin portion 712 of the base 710 and the thin portion 722 of the lower pressing body 720, and the hinge portion by the hooked portion 713 of the base 710 and the thin portion 733 of the upper pressing body 730, respectively. The lower pressing body 720 and the upper pressing body 730 have a sufficient shape restoring force (the above-mentioned rotating biasing force) to rotate in a direction away from the base 710, and the medical hemostatic device is in a deployed state. When the lower pressing body 720 and the upper pressing body 730 are locked to the base body 710 and completely overlapped after being deformed from the compressed state to the compressed state, the same sufficient shape restoration is possible. Force (the above-mentioned rotational biasing force).

[How to use and effects]
In order to perform hemostasis of the puncture hole of the puncture portion of the hemostasis subject using the medical hemostasis device of the present embodiment, the medical hemostasis device is deformed from the expanded state to the compressed state and locked. At this time, as described above, the medical hemostatic device in the deployed state is placed on the upper surface of the base portion 731 of the upper pressing body 730 and the lower surface of the base portion 721 of the lower pressing body 720, respectively (for example, thumb and index finger). The upper pressing body 730 and the lower pressing body 720 are brought close to the base body 710 by applying a force in the direction of approaching each other and pressing the belly of the upper pressing body 730, thereby The hooked portion 714 can be easily and reliably locked, and the hooked portion 713 of the base 710 can be hooked on the hooked portion 724 of the lower pressing body 720 to be easily and reliably locked. Using a finger, the medical hemostatic device can be quickly and easily fixed from the expanded state to the compressed state with one touch only with one hand. Next, a pad 741 attached to the lower surface of the base 721 of the lower pressing body 720 of the medical hemostatic device in the locked state is, for example, as shown in FIG. A doctor or the like) with the needle of the syringe I inserted into the puncture portion of the subject's skin (with a normal hemostasis pad or cotton cloth pressed against the hemostasis subject's skin) While pressing with the finger F around, the injection needle of the syringe I is pulled out from the puncture part of the hemostatic subject. At this time, as shown in FIG. 30 (b), the medical worker presses the pad 741 of the medical hemostatic tool around the puncture portion of the skin of the subject to be stopped with the belly of the finger F.

  Thereafter, as shown in FIG. 30 (c), a medical worker applies a medical pad such as an adhesive tape or an adhesive tape for fixing gauze (preferably, an adhesive tape to a predetermined tape holder with a tape cutter). A pair of adhesive tapes T, T cut to the desired length (with attached adhesive tape pulled out with one hand and cut to the desired length) are pressed against the puncture part of the subject's skin A cross is applied to the skin of the subject to be hemostatically centered on a medical hemostatic device. That is, first, a medical worker cuts to a desired length with respect to the upper surface (the upper surface of the base portion 731 of the upper pressure body 730) of the medical hemostatic device pressed against the puncture portion of the skin of the hemostasis subject. The adhesive tape T is adhered to the lengthwise center portion of the adhesive tape T (while removing the self-finger F holding the medical hemostatic device), and the adhesive tape T is left in the horizontal direction (the length direction of the base 710). Alternatively, it is attached to the skin of the subject to be hemostatic (skin around the hemostatic part for medical use) along either the vertical direction (the width direction of the base 710). In this state, the medical hemostatic tool is pressed and fixed around the puncture portion of the skin of the hemostasis target person with a single adhesive tape T. After that, the medical worker further above the adhesive tape T previously attached to the upper surface of the medical hemostatic device fixed to the puncture portion of the skin of the subject to be stopped with one adhesive tape. Then, the lengthwise central portion of the other adhesive tape T cut to a desired length is attached, and the adhesive tape T is directly stretched along the direction (vertical or horizontal) perpendicular to the previous adhesive tape T. Adhere to the skin of the hemostatic subject (skin around the hemostatic site for medical use). Thereby, an external force (a large external force exceeding the adhesive force of the two adhesive tapes T) that the medical hemostatic device as a whole is intentionally detached from the periphery of the puncture portion of the skin of the hemostasis target person. As long as it is not added, it is impossible to detach and is fixedly bonded, and the pad 741 maintains a fixed position state or a fixed position state facing the periphery of the puncture portion of the skin of the hemostatic subject.

  At this time, the adhesive tapes T, T are used for the latching portion 714 of the base 710 and the lower pressing body 720 protruding upward from the four corners of the upper surface of the medical hemostatic device (the upper surface of the base 731 of the upper pressing body 730). It sticks on the upper surface of the base 731 of the upper pressing body 730 through the space between the hooks 714 and 724 so as not to interfere with the hook 724. Therefore, as the adhesive tapes T, T, a tape having a width smaller than the gap between the pair of hooks 714 and the gap between the pair of hooks 724 of the medical hemostatic tool is used. That is, the width dimension (a dimension in a direction parallel to the gap between the pair of hooks 714 and the gap between the pair of hook parts 724) is long for the medical hemostatic device (as in the case of the present embodiment). When set to be smaller than the size, the width of the adhesive tapes T and T is preferably smaller than the gap between the pair of hooks 714 and the gap between the pair of hooks 724. On the other hand, for the medical hemostatic device, when the length dimension (dimension in the direction parallel to the gap between the opposing latching 714 and the latching part 724) is set smaller than the width dimension, the adhesive tape T, The width of T is preferably smaller than the gap between the opposing latching 714 and the latching portion 724.

  In this way, when the medical hemostatic tool is fixed to the skin of the hemostasis subject with the adhesive tapes T and T, the pad 741 surrounds a certain part of the skin centering on the puncture hole of the puncture portion, that is, 3 The upper pressing body located on the uppermost side so that the center positions of the base 711 of the base body 710, the base 721 of the lower pressing body 720, and the base 731 of the upper pressing body 730 are in the vicinity of the puncture hole. The base portion 731 of 730 is positioned and fixed around the puncture portion of the skin of the hemostatic subject. Even in this state (that is, in a compressed state before the medical hemostatic device is deployed), the pad 741 attached so as to cover almost the entire lower surface of the base 721 of the lower pressing body 720 is hemostatic. It can be expected that it directly contacts the puncture portion of the subject's skin and suppresses bleeding from the puncture hole to some extent.

  Thereafter, the medical worker returns the medical hemostatic device from the compressed state to the expanded state, and shifts to the original hemostatic operation of the puncture portion of the hemostasis subject by the medical hemostatic device. Specifically, as shown in FIG. 30 (d), the medical staff is fixed (in a compressed state) around the puncture portion of the subject's skin by means of two adhesive tapes T, T. In the hemostatic device, the upper pressing body 730 and the base body 710 that are locked to each other are elastically deformed by the finger F toe and the like, and the release portion 734 is moved upward by the finger F toe and the like. By pushing up, the hooked portion 732 can be detached from the hooking surface 714a of the hooking portion 714, and the lock of the hooked portion 732 by the hooking portion 714 can be easily and reliably released. Accordingly, the upper pressing body 730 is turned from the compressed state in which the upper pressing body 730 is overlapped with the base body 710 in FIG. 23 from the rotation biasing force (that is, the upper pressing body 730 is overlapped with the base body 710) of the hinge portion (the hooked portion 713 and the thin portion 733). The elastic urging force that rotates upward to the expanded state shown in FIG. Similarly, in the medical hemostatic device in the fixed state and the compressed state, the medical worker holds the latching portion 724 on the lower pressing body 720 and the base body 710 in the locked state by the toe of the finger F or the like. The hooked portion 713 is detached from the hooking surface 724a of the hooking portion 724 by elastically deforming rearward and pushing the release portion 735 upward by a fingernail or the like. The lock 713 can be easily and reliably released. Accordingly, the lower pressing body 720 is turned from the compressed state in which the lower pressing body 720 is overlapped with the base body 710 from the compressed state in which the lower end pressing body 720 is overlapped with the base body 710 in FIG. The elastic urging force that rotates downward to the expanded state shown in FIG.

  As a result, the adhesive tape T is fixed around the puncture portion of the subject's skin by two adhesive tapes T and T (that is, not only fixed in the front / rear / right / left direction but also separated from the skin in the thickness direction). The medical hemostatic device (fixed with the pad 741 in intimate contact with the skin) is changed from the compressed state shown in FIG. 31A to the expanded state shown in FIG. The rotational biasing force of the pressing body 720 (an elastic biasing force that is a rotational force in the direction away from the base 710) and the rotational biasing force of the upper pressing body 730 (the rotation in the direction away from the base 710 upward). The peripheral force centering around the puncture hole H of the puncture portion of the skin S is placed on the pad 741 on the lower surface of the lower pressing body 720 by the urging force obtained by adding the elastic urging force that is power. Combined rotational biasing force and Pressed by a predetermined pressing force) which is determined by the pressure area of the head 741 or the like. That is, in the medical hemostatic tool, when the base 710 and the upper pressing body 730 are unlocked, the upper pressing body 730 is attached to the upper surface of the base portion 731 by the pair of adhesive tapes T and T, so that the skin S The upper pressing body 730, which is fixed so as not to move upward, is prevented from rotating upward by the adhesive tapes T, T, and the hinge part (thin part 713 and The rotational biasing force by the hooked portion 733) is transmitted as a force that presses and moves the base 710 relatively downward with respect to the upper pressing body 730, and as a result, the upper pressing body 730 and the upper pressing body 730 via the hinge portion. The connected base 710 is pressed downward with a predetermined pressing force (that is, the rotational biasing force). In addition, in the medical tourniquet, when the base 710 and the lower pressing body 720 are unlocked, the rotation urging force of the lower pressing body is transmitted to the base 710. At this time, the base 710 Is fixed to the upper surface of the base 731 of the upper pressing body 730 so as not to move upward with respect to the skin S of the person to be hemostatic, and the unlocked lower side. The rotational biasing force of the pressing body 720 is such that the base 710 is prevented from moving upward by the adhesive tapes T and T, and the rotational biasing force by the hinge portions (thin portion 712 and thin portion 722) is This is transmitted as a force for rotating the side pressing body 720 downward with respect to the base body 710. As a result, the lower pressing body 720 connected to the base body 710 via the hinge portion is moved downward by a predetermined pressing force (that is, the above-mentioned Rotating force) . Thereby, as shown in FIG. 31 (b), the pad 741 on the base 721 of the lower pressing body 720 has a large pressing area and a large elastic pressing force. The peripheral part centering on H can be surely strongly pressed, and bleeding from the puncture hole H can be completely suppressed.

  In this manner, the medical hemostatic device of the present embodiment unlocks the lower pressing body 720 and the upper pressing body 730 that are locked with respect to the base 710 quickly and smoothly with one touch using a fingertip. The hemostasis operation after the injection needle is pulled out from the skin S of the hemostasis subject can be performed very quickly and reliably. Thereafter, when the hemostasis is completed after a lapse of a certain time, the medical staff or the hemostasis target himself / herself peels off the adhesive tapes T and T from the medical hemostasis, and the medical hemostasis is removed from the skin S of the hemostasis subject. Remove from the puncture site. As a result, the pressure applied to the puncture portion by the pad 741 of the medical hemostatic tool is released, and the puncture portion of the skin of the hemostasis target person returns to the normal state.

  By the way, in the said embodiment, the said pad 741 is previously affixed on the lower surface of the base 721 of the lower side press body 720, and the mounting | wearing operation | movement of the medical hemostatic device to the puncture part of the skin of a hemostatic subject It is very effective in simplifying and shortening the wearing time. However, in some cases, the pad 741 is not attached to the lower surface of the base 721 of the lower pressing body 720 in advance. At the base of the lower pressing body 720, the pad 741 or a cotton cloth instead of the pad 741 or the like is attached to the medical tourniquet immediately after the medical hemostatic device is deformed from the expanded state to the compressed state, or in an extreme case. After being pressed around the puncture portion of the subject's skin without being attached to the lower surface of 721, a medical hemostatic tool is pressed and fixed on the pad, and the adhesive tape T is used as described above. , T using medical hemostatic device It may be or secured around the puncture of the skin of the blood subject.

  Moreover, in the said embodiment, although the medical hemostatic device was fixed to the skin of the hemostatic subject using two adhesive tapes T and T, when sufficient fixing force is obtained only by one sheet (especially, (If a fixing force capable of preventing upward movement is obtained), the medical hemostatic device can be placed in the fourth position by a single adhesive tape T. Alternatively, three or more adhesive tapes T can be used as necessary.

  Furthermore, in the medical hemostatic device of the above-described embodiment, as long as the pressing bodies (the lower pressing body 720 and the upper pressing body 730) can be locked and unlocked with respect to the base body 710, the hooking portion and the hooked portion. The shape and structure may be different from the illustrated example of the above embodiment. For example, as long as the latching part and the latched part perform a latching operation in a concave-convex relationship and can release the latching state in the concave-convex relationship by operating either the latching part or the latched part. In, it can implement | achieve by the combination of the recessed part and convex part of arbitrary shapes. In this case, as in the above-described embodiment, in the latching operation due to the concave and convex relationship, the latching portion may be a concave shape and the latched portion may be a convex shape, and conversely, the latching portion is convex. It may become a part shape, and a to-be-latched part may become a recessed part shape.

  Furthermore, in the above embodiment, one of the release portions 734 and 735 for releasing the locked state of the lower pressing body 720 and the upper pressing body 730 with respect to the base 710 is one of the base 710 and the upper pressing body 730. As long as the unlocking operation (releasing the entire uneven latching relationship) or the unlocking assist operation (releasing the uneven latching relationship) in the locked state due to the uneven latching relationship is possible, other than the above-described release unit 734 The other is the release operation of the locked state of the base body 710 and the lower pressing body 720 (releasing the entire concave / convex latching relationship) or (releasing a part of the concave / convex latching relationship) As long as the release assist operation is possible, the configuration other than the release unit 735 can be adopted.

  Furthermore, since the lower pressing portion needs to apply a pressing force evenly to the entire surface of the predetermined area around the puncture hole of the hemostasis subject via the pad, its outer shape is around the puncture hole of the skin puncture portion. It is necessary to form a flat plate having an outer dimension that covers the entire predetermined area, and an area that covers the entire predetermined area around the puncture hole of the puncture portion of the skin. On the other hand, the base body and the upper pressing body do not directly press the puncture portion of the hemostasis subject, but are members that generate a biasing force for the pressing operation of the lower pressing body to the last, and therefore the outer shape thereof is A flat plate having an outer dimension that covers a predetermined area around the puncture hole of the skin puncture portion, and an area that covers an entire area of the puncture hole of the skin puncture section. In addition, the outer shape has an outer dimension that covers a predetermined area around the puncture hole of the skin puncture portion, while the area is out of the predetermined area around the puncture hole of the skin puncture portion. It is possible to use a ring plate shape or the like that covers only the outer peripheral side portion.

  As shown in FIG. 37, the medical hemostatic device according to the fourteenth embodiment includes a base 1110 as a fixing portion, a lower pressing body 1120 as a first pressing portion (main pressing portion), and a second pressing portion ( The upper pressing body 1130 as an auxiliary pressing portion) is provided, and the base body 1110, the lower pressing body 1120, and the upper pressing body 1130 are integrated, and the lower pressing body 1120 and the upper pressing body 1130 are respectively connected to the base body 1110. It is a one-piece structure that can be brought close to each other (with the base 1110 sandwiched therebetween) and can be superimposed. That is, in the medical hemostatic device of the fourteenth embodiment, as shown in FIGS. 37 and 38, the base body 1110, the lower pressing body 1120, and the upper pressing body 1130 as a whole form a substantially Z-shaped cross section or side surface shape. As described above, a predetermined elastic material is integrally formed by a predetermined manufacturing method. Note that, in the same way as in the above-described embodiment, such a medical hemostatic device with an integrated structure is integrally formed of the base 1110, the lower pressing body 1120, and the upper pressing body 1130 by a synthetic resin material by an injection molding technique from the viewpoint of manufacturing cost. However, it is also possible to integrally form by using other materials or by using other molding methods.

[Substrate]
As shown in FIG. 38, the base 1110 includes a rectangular flat base 1111. Specifically, the base 1111 has a predetermined width dimension (for example, a predetermined dimension within a range of 18 mm to 22 mm, preferably a predetermined dimension of about 19 mm, 20 mm, or 21 mm) and a predetermined length dimension (for example, 20 mm to 24 mm). The rectangular flat plate shape having a predetermined dimension within a range of (preferably, a predetermined dimension of about 21 mm, 22 mm, or 23 mm) is formed. The base portion 1111 has a thin plate shape having a uniform thickness with a predetermined thickness dimension (for example, a predetermined dimension of about 1.2 mm).

[Lower pressing body]
As shown in FIG. 38, the lower pressing body 1120 has a rectangular flat plate-like base 1121 and a position separated by a predetermined distance from the center position in the length direction of the base 1121 (left and right direction in FIG. 38) to one end side. The latching portion 1122 is integrally formed and protrudes upward from the upper surface of the base portion 1121. Specifically, the base 1121 has a rectangular plate shape having a predetermined width dimension (a width dimension slightly larger than the base 1111 of the base body 1110) and a predetermined length dimension. Here, the length of the base 1121 is set to be slightly shorter than the base 1111 of the base 1110. For example, the ratio of the length of the base 1121 to the base 1111 is (the base angle is 35 degrees). ) When assuming a right triangle, the dimensional ratio is the same as the ratio of the length of the base to the hypotenuse when the base 1121 is the base and the base 1111 is the hypotenuse (for example, the base 1111 is about 23 mm) In this case, the base 1121 is about 22 mm). Also, as shown in FIGS. 37 and 38, the latching portion 1122 is a position that is separated from the center position in the length direction by a predetermined distance from the center position in the width direction at both end edges in the width direction of the base portion 1121 of the lower pressing body 1120. Are integrally formed with each other. The latching portion 1122 is a claw-like columnar portion or plate-like portion that projects perpendicularly to the top surface of the base portion 1121 and has a guide surface 1122a and a latching surface 1122b. The guide surface 1122a of the latching portion 1122 extends from the upper end of the latching portion 1122 (the width of the lower pressing body 1120) on the inner surface side of each latching portion 1122 (the surface side where the pair of latching portions 1122 oppose each other). An inclined surface extending downward (in a direction). The latching surface 1122b of the latching portion 1122 is a surface extending in parallel with the base 1121 from the lower end of the guide surface 1122a, and the latching portion 1122 is formed with a claw-shaped latching recess by the latching surface 1122b. Has been.

[Upper pressing body]
As shown in FIG. 38, the upper pressing body 1130 includes a rectangular flat plate-like base 1131. Specifically, the base 1131 is a rectangular flat plate having a predetermined width dimension (a width dimension slightly larger than the base 1111 of the base body 1110 and a width slightly smaller than the base 1121 of the lower pressing body 1120). I am doing. The base portion 1131 of the upper pressing body 1130 has a central portion in the length direction (the extending direction of the base portion 1131 in FIG. 38) as the thickest portion 1132 having the largest thickness, and extends from the thick portion 1132 to both ends in the length direction. It becomes the taper plate shape which becomes thin gradually as it goes. Note that both edge portions of the thick wall portion 1132 (portions located at both edge portions in the width direction of the base portion 1131) function as hooked portions that are hooked by the hook portions 1122 of the lower pressing body 1120. Here, the length of the base 1131 is set to be slightly longer than the length of the base 1111 than the base 1111 of the base 1110 (and the length of the lower pressing body 1120). For example, as shown in FIG. 38, in the entire deployed state of the medical hemostatic device, both end positions in the longitudinal direction of the base body 1110 (inclined state) are positioned at both end positions in the lengthwise direction of the lower pressing body 1120 in the horizontal state. On the other hand (that is, the base body 1110 in the inclined state has a length dimension longer than that of the lower pressing body 1120 by an amount corresponding to the inclination angle), but in a horizontal state (that is, in a state parallel to the lower pressing body 1120) ) At both ends in the length direction of the upper pressing body 1130 come to positions protruding outward by a predetermined length from both ends in the length direction of the lower pressing body 1120. For example, in the upper pressing body 1130, the length of the thick portion 1132 is 4 mm, and the length from both ends of the length of the thick portion to the positions facing both end positions of the lower pressing body 1120 is 9 mm, The length from the position facing both end positions of the lower pressing body 1120 to both ends in the length direction can be set to 7 mm, respectively, and the length can be set to 36 mm as a whole. In this case, the length dimension (36 mm) of the upper pressing body 1130 is about 1.6 times as large as the length dimension (22 mm) of the lower pressing body 1120, and the puncture of the subject to be hemostatic during the hemostasis operation is performed. This is a very effective dimensional ratio in that the pressing force of the part is gradually expressed. In addition, the height dimension of the latching | locking part 1122 of the said lower side press body 1120 can be 6 mm, for example.

[Hinge part]
The medical hemostatic device according to the present embodiment includes one end of the base 1111 of the base 1110 (the lower left end in FIG. 38A) and the base end of the base 1121 of the lower pressing body 1120 (the left end in FIG. 38A). Are integrally connected by a hinge portion 1112. The hinge portion 1112 serves as an intersecting portion and a connecting portion of the base body 1110 and the lower pressing body 1120, and elastically hinges the lower pressing body 1120 to the base body 1110. The first embodiment 8 of the eighth embodiment. It corresponds to the hinge part. Further, the medical hemostatic device of the present embodiment includes the other end of the base 1111 of the base 1110 (upper right end in FIG. 38A) and the base end of the base 1131 of the upper pressing body 1130 (in FIG. 38A). The hinge portion 1113 is integrally connected to a position that is a predetermined distance from the right end). The hinge portion 1113 serves as an intersecting portion and a connecting portion between the base body 1110 and the upper pressing body 1130, and elastically connects the upper pressing body 1130 to the base body 1110. The second hinge section of the eighth embodiment. It corresponds to. The connecting position of the other end of the base portion 1111 to the base portion 1131 (a position inside a predetermined distance from the base end of the base portion 1131) is in a state parallel to the upper pressing body 1130 in the deployed state of the medical hemostatic device. It is a position facing the tip position of the lower pressing body (the right end position in FIG. 38 (a)).

[Lock part]
In the medical hemostatic device of the present embodiment, the locking portion 1222 of the lower pressing body 1120 and the thick portion 1132 as the hooked portion of the upper pressing body 1130 are pressed downward with the base body 1110 interposed therebetween. The lower pressing body 1120 and the upper pressing body 1130 are locked (or fixedly fixed) to the base body 1110 so as to maintain a compressed state in which the body 1120 and the upper pressing body 1130 are superposed on the base body 1110 in a close contact state or a substantially close contact state. It constitutes the lock part. Specifically, the medical hemostatic device is in a predetermined state shown in FIGS. 37 to 39 in a normal state (a state after molding and no external force is applied to any part), that is, A state in which the lower pressing body 1120 and the upper pressing body 1130 are separated from the base body 1110 in a bent state at a predetermined angle (for example, a predetermined angle within a range of 20 degrees to 40 degrees, preferably about 30 degrees). It is in. From this developed state, for example, in a direction in which the belly of a finger (for example, thumb and index finger) is pressed against the upper surface of the base portion 1131 of the upper pressing body 1130 and the lower surface of the base portion 1121 of the lower pressing body 1120 to approach each other. When a force is applied to bring the upper pressing body 1130 and the lower pressing body 1120 closer to the base body 1110, the thick portion 1132 as the hooked portion of the upper pressing body 1130 is hooked on the lower pressing body 1120. The medical hemostatic device can be fixed from the expanded state to the compressed state with one touch only with one hand using a finger.

  At this time, as shown in FIG. 39, the pair of latching portions 1122 is different from the latching portions 714 and 724 (standing from the base 711 and the base 721) of the eighth embodiment, respectively (base 1121 In the width direction of the base 1121, the base 1121 is inclined and protrudes outward. In other words, the distance or gap dimension between the upper ends of the outer surfaces of the pair of latching portions 1122 is the width between both ends of the base 1121 of the lower pressing body 1120 (and the upper pressing body 1130 in parallel with the lower pressing body 1120. The width of the base portion 1131 between the both ends in the width direction) is larger than the width of the base portion 1131, and the front end position of the latching surface 1122b, which is the intersection of the guide surface 1122a and the latching surface 1122b, is the lower pressing body in the compressed state. 1120 overlaps with the lower pressing body 1120 (in a state parallel to the lower pressing body 1120), and is located slightly inside the width direction both ends of the base 1131 of the upper pressing body 1130, and the upper pressing body 1130 overlaps the lower pressing body 1120. , Both end edges in the width direction of the base portion 1131 of the upper pressing body 1130 pass on the phantom line shown by the alternate long and short dash line in FIG. 39 and the lower end of the guide surface 1122a of the latching portion 1122 To come into contact slightly portion only of. Alternatively, the distance or gap dimension between the upper ends of the outer surfaces of the pair of latching portions 1122 is further increased, and the leading end position of the latching surface 1122b overlaps with the lower pressing body 1120 in the compressed state (with the lower pressing body 1120 and When the upper pressing body 1130 is overlapped with the lower pressing body 1120 so as to be positioned outside the both ends in the width direction of the base 1131 of the upper pressing body 1130 (in a parallel state), the base 1131 of the upper pressing body 1130 It is also possible to configure such that both end edges in the width direction pass through a position outside the phantom line indicated by a one-dot chain line in FIG. 39 and do not contact the guide surface 1122a of the latching portion 1122 at all.

  Here, the medical hemostatic device of the eighth embodiment is provided with a pair of hooking portions 714 at both ends of one end edge in the length direction of the base 710, and a pair at both ends of the other end edge in the length direction of the lower pressing body 720. By providing a total of four latching portions 714 and 724, the lower pressing body 720 and the upper pressing body 730 can be locked with respect to the base 710 with one hand. However, in the medical hemostatic device of the fourteenth embodiment, the number of the latching portions is reduced to two (only one pair) (from four in the embodiment), and a pair (two) of the latching portions. Only 1122 allows the lower pressing body 1120 and the upper pressing body 1130 to be locked with respect to the base body 1110 with one hand. Specifically, the latching portion 1122 of the lower pressing body 1120 is not the center position in the length direction of the base portion 1131 of the upper pressing body 1130 on the latched side in the deployed state, but the tip of the lower pressing body 1120. The latching portion 1122 is disposed at a position separated by a predetermined distance on the side, and the lower pressing body 1120 and the upper pressing body 1130 are overlapped with the base body 1110 in a compressed state. The length of the upper pressing body 1130 when it comes to the closest state to 1120 (that is, when the upper surface of the thick portion 1132 comes to a position beyond the front end of the engaging surface 1122b of the engaging portion 1122). This is a position where the thick portion 1132 at the center in the vertical direction is disposed (the length direction of the lower pressing body 1120).

[Malfunction prevention structure]
This configuration is a malfunction prevention structure that prevents the original hemostatic operation of the medical hemostatic device (in a compressed state) from being inadvertently operated by a person to be hemostatic or the like. That is, it is customary for a hemostatic subject to press and squeeze the puncture part after injection with a cotton cloth or the like as common knowledge based on information from medical personnel or the like. Even when hemostasis is performed with a hemostasis device, the compressed medical hemostasis device is fixed to the puncture part of the hemostasis subject with an adhesive tape, the shape is restored to the expanded state, and the hemostasis subject himself / herself is started. However, it is conceivable that the upper surface of the medical hemostatic device is accidentally pressed, and in this case, the medical hemostatic device is configured to be automatically compressed by pressing as in the eighth embodiment. May return from the expanded state to the compressed state again and stop the original hemostatic operation. Therefore, in order to avoid such a situation, after the compressed hemostatic device is fixed to the puncture part of the hemostatic subject with an adhesive tape, the shape is restored to the expanded state and the hemostatic operation is started. However, even when the upper surface of the medical hemostatic device is accidentally pressed, the above structure is used as a structure in which the thick portion 1132 of the upper pressing body 1130 is not automatically hooked to the hooking portion 1122 of the lower pressing body 1120. Adopted.

[How to use and effects]
Specifically, in order to use the medical hemostatic device of the present embodiment to stop the puncture hole of the puncture portion of the hemostasis target person, the medical hemostatic device is deformed from the expanded state to the compressed state. Lock it. At this time, as described above, the medical hemostatic device in the deployed state is placed on the upper surface of the base portion 1131 of the upper pressing body 1130 and the lower surface of the base portion 1121 of the lower pressing body 1120, respectively with fingers (for example, thumb and index finger). The upper pressing body 1130 and the lower pressing body 1120 are moved closer to each other with the base body 1110 interposed therebetween so that the upper pressing body 1130 is pressed as the hooked portion of the upper pressing body 1130. The thick wall portion 1132 is hooked and locked to the hook portion 1122 of the lower pressing body 1120. At this time, in the present embodiment, since the pair of latching portions 1122 are in a state of opening and inclining toward each other in the width direction of the medical hemostatic device, the upper pressing body 1130 and the lower pressing body 1120 are brought closer to each other. Even if the thick wall portion 1132 comes to a position beyond the hooking surface 1122b of the hook portion 1122, the thick wall portion 1132 can be hooked on the hook portion 1122 with a sufficient hooking force. Instead, the lower pressing body 1120 and the upper pressing body 1130 attempt to restore the shape of the base body 1110 by the rotational biasing force of the hinge part, and the latching of the thick part 1132 by the latching part 1122 is released. Therefore, in the present embodiment, when the upper pressing body 1130 and the lower pressing body 1120 are brought close to each other and the thick portion 1132 comes to a position beyond the hooking surface 1122b of the hooking portion 1122, a pair of The latching portions 1122 are pressed in a direction approaching each other (by a finger or the like), and the latching portions 1122 are plastically deformed so as to be in a suspended state (even in the width direction) with respect to the base 1121 of the lower pressing body 1120. To do. That is, the latching portion 1122 is made of a plastically deformable material and does not automatically return to its shape when an external force is released by elastic deformation. Therefore, when the thick portion 1132 comes to a position beyond the latching surface 1122b of the latching portion 1122, the pair of latching portions 1122 are pressed in a direction approaching each other so as to be suspended. By plastically deforming the portion 1122, the latching surface 1122b of the latching portion 1122 securely latches the upper surface of the thick portion 1132, and the locking operation is completed. In the present embodiment also, it is preferable to attach a pad (similar to the eighth embodiment) on the lower surface of the base 1121 of the lower pressing body 1120.

  Thereafter, in the same manner as in the eighth embodiment, the medical tourniquet is fixed to the puncture portion of the hemostasis subject with an adhesive tape, the compressed medical tourniquet is unlocked, and the shape is restored to the expanded state. Perform hemostasis. At this time, the pair of latching portions 1122 are pressed outward to plastically deform, and the shape is restored to the inclined protruding state shown in FIG. 39 (by plastic deformation). As a result, the medical hemostatic device is unlocked, restored in shape from the compressed state to the expanded state, and performs an original hemostatic operation. That is, in the present embodiment, the latching portion 1122 as the lock portion is configured to be plastically deformable, and thus functions as a lock release portion. After this, even when the hemostasis subject himself / herself accidentally presses the upper surface of the medical hemostatic device, the pair of hooking portions 1122 are in the state of opening outward, so the thick portion 1132 of the upper pressing body 1130 Is not automatically hooked on the hooking portion 1122 of the lower pressing body 1120, and does not hinder the hemostatic operation.

  By the way, the width dimensions of the base body 1110, the lower pressing body 1120, and the upper pressing body 1130 can be different from those described above (all can be the same). In addition, although it is effective for the above-described operation to gradually increase the pressing force as described above, it is effective that the length of the upper pressing body 1130 is considerably larger than the length of the lower pressing body 1120. It can be made the same as the length of the pressing body 1120, or can be made slightly larger (or smaller in an extreme case). In addition, the specific dimensions shown in each of the above-described embodiments are only preferable examples, and the medical hemostatic device of the present invention is not limited to the above-described dimension values.
