[First embodiment]
1-5 illustrate a compression device 1 according to one embodiment of the present disclosure. Specifically, FIG. 1 is a perspective view of the compression device 1 as viewed from above. 2 and 3 are plan views of the compression device 1. FIG. Specifically, FIG. 2 is a top view of the compression device 1 . FIG. 3 is a bottom view of the compression device 1. FIG. In FIGS. 2 and 3, for convenience of explanation, the position of the blood vessel BV when the compression device 1 is attached to the surface of the living body is indicated by a chain double-dashed line. 4 and 5 are cross-sectional views of the compression device 1 at the same cross-section. 4 and 5 show different states of the compression device 1, details of which will be described later.

The compression device 1 includes an adhesive body 2 and a compression member 3. The adhesive body 2 has an adhesive surface 2a that can be attached to the surface of a living body. The compression member 3 is fixed to the adhesive body 2 . The pressing member 3 includes a pressing portion 6a capable of pressing the surface of the living body while the sticking surface 2a of the sticking body 2 is stuck to the surface of the living body.

Of the directions orthogonal to the sticking surface 2a, the direction from the surface opposite to the sticking surface 2a of the sticking body 2 toward the surface having the sticking surface 2a is the direction of the compression device. 1 is the sticking direction of sticking to the surface of the living body, and is hereinafter simply referred to as "downward direction A1" or "lower side" for convenience of explanation. In addition, of the directions orthogonal to the sticking surface 2a, the direction opposite to the downward direction A1 is the separation direction in which the compression device 1 is separated from the living body surface. ”.

Furthermore, among the planar views (see FIGS. 2 and 3) of the compression device 1 viewed along the direction orthogonal to the sticking surface 2a, the planar views viewed from the upper side toward the downward direction A1 (see FIG. 2) is simply referred to as "top view" for convenience of explanation. In addition, among the planar views (see FIGS. 2 and 3) of the compression device 1 viewed along the direction orthogonal to the sticking surface 2a, the planar views viewed from the lower side toward the upward direction A2 (see FIG. 3) ) is simply referred to as “bottom view” for convenience of explanation. In addition, when a top view and a bottom view are not distinguished, they may simply be described as a “planar view”. Further, unless otherwise specified, simply describing "planar view", "top view", and "bottom view" means that an expanded portion of the compression member 3 as a pressing portion 6a, which will be described later, is in a contracted form. plan view, top view, and bottom view.

As shown in FIGS. 1 to 5, the adhesive body 2 of the present embodiment is an adhesive sheet 4 having an adhesive surface 2a on one side in the thickness direction A and an adhesive surface 2a that can be attached to the surface of a living body. In the present embodiment, the “direction orthogonal to the sticking surface 2 a ” described above is the same direction as the thickness direction A of the sticking sheet 4 . The sticking surface 2a is covered with a liner such as a release sheet in the pre-use state before sticking to the surface of the living body (see FIG. 7A). The liner is peeled off and removed immediately before the adhesive surface 2a is attached to the surface of the living body. The sticking sheet 4 as the sticking body 2 shown in FIGS. 1 to 5 shows a state of use in which the liner is removed and the sticking surface 2a is exposed.

As shown in FIGS. 1 to 5, the compression member 3 of this embodiment is fixed to the adhesive sheet 4. As shown in FIGS. Specifically, the compression member 3 of this embodiment is fixed to a fixing surface 2b, which is the upper surface of the adhesive sheet 4 on the side opposite to the adhesive surface 2a. The pressing member 3 includes a pressing portion 6a capable of pressing the surface of the living body at a position different from the position where the sticking surface 2a is stuck while the sticking surface 2a is stuck to the surface of the living body.

The compression device 1 of the present embodiment has a configuration including the adhesive body 2 and the compression member 3, but is not limited to this configuration. The compression device 1 may have a configuration including the adhesion surface 2a and the pressing portion 6a, and the adhesion body 2 and the compression member 3 may have configurations different from those of the present embodiment. Moreover, the compression device 1 does not have to be composed of a combination of the adhesive body 2 and the compression member 3 . In other words, the compression device 1 may be, for example, an integrally molded product, or may be configured by combining any number of members equal to or greater than three.

Thus, the compression device 1 is fixed in position on the surface of the living body by attaching the sticking surface 2a to the surface of the living body. According to the compression device 1, a predetermined site on the surface of the living body can be compressed by the pressing portion 6a while the sticking surface 2a is stuck on the surface of the living body. The predetermined site on the surface of the body includes, for example, a wound on the surface of the body formed by inserting a medical insertion member such as a puncture needle, a catheter, or a sheath into a blood vessel of the body, or its vicinity. After the above-described medical insertion member is removed from the living body, the pressing part 6a presses the wound on the surface of the living body or its vicinity, thereby forming a subcutaneous blood vessel or a perforation extending from the blood vessel to the surface of the living body. , can be pressed from the biological surface. Hemostasis can be achieved by applying pressure with the pressing portion 6a for a predetermined period of time.

Here, as shown in FIGS. 2 and 3, the sticking surface 2a is attached to the pressing portion 6a in a direction perpendicular to the extending direction C of the blood vessel BV on the surface of the living body (hereinafter simply referred to as "width direction B"). ), it has a side sticking surface 2a1 to be stuck to the surface of the living body. As shown in FIGS. 2 and 3 , in the compression device 1, in a plan view, there is provided a position between the pressing portion 6a and the side sticking surface 2a1 of the sticking surface 2a, perpendicular to the sticking surface 2a. A lateral opening 50 is defined therethrough. In other words, the side opening 50 is an opening that linearly penetrates the compression device 1 in a direction orthogonal to the sticking surface 2a.

Since the compression device 1 partitions the side openings 50, even if blood leaks around the pressing part 6a, the blood leaks out through the side openings 50 without peeling the sticking surface 2a from the surface of the living body. Blood can be removed.

Blood removal may be performed, for example, by pushing a blood removal member 80 (see FIG. 7F) such as a cotton ball or gauze through the lateral opening 50 . In addition to removing blood, the lateral opening 50 may also be used to press a wound on the surface of the body or its vicinity with a finger.

Details of each member and each part of the compression device 1 of this embodiment will be described below. In the present embodiment, for convenience of explanation, one of the extending directions C of the blood vessel BV is referred to as the forward direction C1 and the other is referred to as the backward direction C2. The forward direction C1 means the side of the compression device 1 that receives the medical insertion member 100 (see FIG. 7A, etc.) such as a sheath. The forward direction C1 in this embodiment refers to the side where the receiving portion 8 is provided. The rearward direction C2 is the opposite direction of the forward direction C1 in the extending direction C. As shown in FIG.

<Adhesion body 2>
As described above, the adhesive body 2 of this embodiment is the adhesive sheet 4 . The adhesive sheet 4 has flexibility. Therefore, the adhesive sheet 4 can be deformed along the shape of the surface of the living body. In addition, the sticking surface 2a can easily follow the deformation of the surface of the living body. As a result, unintentional detachment of the compression device 1 from the surface of the living body can be suppressed.

The sticking surface 2a of the sticking sheet 4 of the present embodiment is constituted by the entire lower surface of the sticking sheet 4. The sticking surface 2 a of the sticking sheet 4 may be provided only on a partial area of the lower surface of the sticking sheet 4 .

The adhesive sheet 4 is composed of multiple layers including, for example, a base material layer and an adhesive layer.

The base material layer is composed of, for example, a thin resin sheet. More specifically, the base layer is made of, for example, a white spunlace nonwoven fabric of polyester fibers, and its thickness is in the range of 5 μm to 150 μm, such as 30 μm. However, the material of the base layer is not limited to polyester, and may be, for example, acrylic polymer, polyethylene, ethylene-vinyl acetate copolymer, polyurethane, or polyamide derivative.

The adhesive layer is composed of, for example, an adhesive such as a rubber-based adhesive, an acrylic-based adhesive, or a silicon-based adhesive. The adhesive layer is laminated on the base material layer directly or indirectly with another layer interposed therebetween. The sticking surface 2a of the sticking sheet 4 of this embodiment is composed of an adhesive layer.

The adhesive sheet 4 may further include another layer in addition to the base material layer and adhesive layer described above. The adhesive sheet 4 may include, for example, a surface layer. The surface layer is made of resin having a thickness of about 5 μm to 50 μm, for example. More specifically, polyester, polyamide, polyamide-imide, polyethylene, polypropylene, polycarbonate, polyurethane, polyvinyl chloride, fluororesin, etc. can be used as the material of the surface layer. The surface layer is laminated on the opposite side of the adhesive layer with the substrate layer interposed therebetween, either directly or indirectly with another layer interposed therebetween. Therefore, the upper surface of the adhesive sheet 4 may be composed of the surface layer.

More specifically, the adhesive sheet 4 may be composed of a non-woven fabric tape with a pressure-sensitive adhesive applied to one surface. Furthermore, the adhesive sheet 4 may be composed of a double-sided tape having adhesive layers provided on both sides of the base material layer. When the adhesive sheet 4 is made of a double-sided tape, the pressure member 3 is fixed to the adhesive sheet 4 by adhering the later-described support portion 7a of the pressure member 3 to one adhesive layer of the adhesive sheet 4. can do.

The adhesive sheet 4 of the present embodiment has a substantially C-shaped outer shape in plan view (see FIGS. 2 and 3). As shown in FIGS. 2 and 3, the adhesive sheet 4 of this embodiment covers only a portion of the lower surface side of the compression member 3 . Specifically, the adhesive sheet 4 of this embodiment covers only the outer edge region of the lower surface of the compression member 3 . The adhesive sheet 4 of this embodiment is fixed only to the outer edge region of the lower surface of the compression member 3 . In other words, the adhesive sheet 4 of this embodiment does not cover the central region of the lower surface of the compression member 3 where the expanded portion as the pressing portion 6a of the compression member 3 is located. In addition, the adhesive sheet 4 of the present embodiment does not cover the entire outer edge region of the lower surface of the compression member 3, but partially covers the outer edge region. That is, the adhesive sheet 4 of this embodiment does not cover a part of the outer edge area of the lower surface of the compression member 3 . In this embodiment, the portion of the compression member 3 that is not covered with the adhesive sheet 4 in the outer edge region of the lower surface of the compression member 3 is the portion adjacent to the receiving portion 8 . Receiving portion 8 is a portion capable of receiving a medical insertion member that is or has been inserted into a body vessel BV (see FIGS. 2 and 3). The receiving portion 8 of the present embodiment is a gap defined between both ends of the adhesive sheet 4 which is substantially C-shaped in plan view.

Here, as shown in FIGS. 2 and 3, the extension direction C described above in this embodiment is one end of the outer edge of the compression device 1 (FIGS. 2 and 3) where the receiving portion 8 is provided in plan view. 3) and the other end of the outer edge of the compression device 1 (upper end in FIGS. 2 and 3) on the side opposite to the position where the receiving part 8 is provided (upper end in FIGS. 2 and 3). , vertical direction in FIG. 3). The side sticking surface 2a1 of the present embodiment is arranged at a position separated from the pressing portion 6a in the horizontal direction (horizontal direction in FIGS. 2 and 3) orthogonal to the vertical direction in plan view. This lateral direction is a direction substantially equal to the width direction B described above.

Furthermore, as shown in FIG. 3, the extension direction C and the vertical direction in the present embodiment are, in a plan view, one end (lower end in FIG. 3) of the pressing portion 6a connected to the extending portion 6b, The linear direction (vertical direction in FIG. 3) passing through one end of 6a connected to the extended portion 6b and the other end (upper end in FIG. 3) on the opposite side is substantially the same. Therefore, the position of the side sticking surface 2a1 of the present embodiment may be defined by the positional relationship with the position of one end of the pressing portion 6a connected to the extending portion 6b.

Furthermore, the above-described width direction B in the present embodiment is substantially the same as the facing direction in which two gripping portions 7b of the support body 7, which will be described later, face each other in a plan view. That is, this facing direction is substantially the same as the lateral direction of the compression device 1 described above.

As described above, the side sticking surface 2a1 of the present embodiment is arranged in a plane view with respect to the pressing portion 6a in the width direction B, the lateral direction defined by the above-described receiving portion 8, the gripping portion 7b, and the like. are spaced apart from each other.

<Compression member 3>
The compression member 3 of this embodiment includes a pressing portion 6a and a support portion 7a. More specifically, the compression member 3 of this embodiment includes a pressing body 6 and a support 7 . The pressing portion 6 a of this embodiment is configured by a part of the pressing body 6 . Further, the support portion 7a of this embodiment is configured by a part of the support body 7. As shown in FIG. Details of the pressing body 6 and the support body 7 of the present embodiment will be described below.

The pressing body 6 of this embodiment includes a pressing portion 6a and an extending portion 6b.

The pressing part 6a can press the surface of the living body while the sticking surface 2a is stuck to the surface of the living body. Specifically, the pressing portion 6a of the present embodiment extends in the thickness direction A, which is a direction orthogonal to the sticking surface 2a, in a state where the sticking surface 2a is stuck to the surface of the living body, thereby increasing the pressure on the surface of the living body. can be pressed. Further, the pressing portion 6a of the present embodiment can press the surface of the living body at a position where the adhesive sheet 4 does not exist in plan view. That is, the pressing portion 6a of the present embodiment can press the surface of the living body without the adhesive sheet 4 interposed therebetween.

The pressing portion 6a of the present embodiment is configured by an expansion portion that defines a housing space 6a1 that can contain a fluid such as gas. More specifically, the expanding portion as the pressing portion 6a of this embodiment is composed of two

balloon portions

10a and 10b that are connected so that the inside thereof communicates. The accommodation space 6a1 of this embodiment is configured by an internal space in which the two

balloon portions

10a and 10b communicate.

The expansion part as the pressing part 6a can be expanded in the downward direction A1 in the thickness direction A by supplying fluid to the housing space 6a1. FIG. 4 shows the contracted form before the expanding part as the pressing part 6a expands, and FIG. 5 shows the expanded form after expanding the expanding part as the pressing part 6a from the contracted form. The expansion part as the pressing part 6a of the present embodiment expands in the downward direction A1 by changing form from the contracted form (see FIG. 4) to the expanded form (see FIG. 5), and can press the surface of the living body. posture. More specifically, the expanded portion as the pressing portion 6a expands in the downward direction A1 by receiving a reaction force from the lower surface of the support portion 7a of the support body 7 when the fluid is supplied to the accommodation space 6a1. . The fluid supplied to the accommodation space 6a1 of the expansion portion as the pressing portion 6a is not limited to gas, and may be liquid.

As shown in FIG. 4, the contracted pressing portion 6a is arranged along the lower surface of the support portion 7a of the support body 7 in a state where the accommodation space 6a1 is contracted. A housing space 6a1 of the pressing portion 6a communicates with a tube 28 extending to the outside of the support 7. As shown in FIG. A fluid such as air is supplied through the tube 28 from a fluid supply device connected to an inflation port as a connecting portion 29 provided at the end of the tube 28 to the housing space 6a1 of the pressing portion 6a. As a result, the expanded state of the pressing portion 6a can be changed, and the pressing portion 6a can be changed from the contracted form (see FIG. 4) to the expanded form (see FIG. 5).

The pressing part 6a of the present embodiment is in a state where the sticking surface 2a of the sticking sheet 4 as the sticking body 2 is stuck to the surface of the living body (hereinafter simply referred to as the "sticking state of the compression device 1"). ) is arranged between the surface of the living body and the lower surface of the support portion 7a. When the pressing portion 6a expands in the thickness direction A due to the supply of fluid in the attached state of the compression device 1, the pressing portion 6a is sandwiched between the living body surface and the supporting portion 7a to press the living body surface. In other words, the contracted pressing portion 6a of the present embodiment does not press the surface of the living body while the compression device 1 is attached. However, it is sufficient that the pressing portion 6a can press a predetermined site on the surface of the living body with a desired pressing force by changing its form from a contracted form to an expanded form while the compression device 1 is attached. That is, the contracted pressing portion 6a may press the surface of the living body while the compression device 1 is attached.

The extension part 6b extends like a sheet from the pressing part 6a. The extending portion 6b has flexibility. The extension portion 6b is wound around the support portion 7a. Thus, the extended portion 6b extends from the pressing portion 6a to the upper surface side of the supporting portion 7a on the side opposite to the pressing portion 6a across the supporting portion 7a. The extending portion 6b is engaged with the support portion 7a on the upper surface side of the support portion 7a.

Specifically, the support portion 7a of the present embodiment defines a front through-hole 7a1 penetrating in the thickness direction A. In addition, the support portion 7a of the present embodiment includes locking projections 7a2 that protrude upward A2. The extension portion 6b of the present embodiment is wound around the support portion 7a through the front through hole 7a1. More specifically, the extended portion 6b of the present embodiment extends from the lower side where the pressing portion 6a is positioned across the support portion 7a through the front through hole 7a1 to the upper side, which is the opposite side. . The extended portion 6b of the present embodiment is wound around the support portion 7a along the inner surface of the support portion 7a that defines the front through hole 7a1 and the upper surface of the support portion 7a. A locking hole 6b1 into which the locking protrusion 7a2 is fitted is formed in the extending portion 6b on the upper surface side of the support portion 7a. By fitting the locking projection 7a2 into the locking hole 6b1, the extended portion 6b is positioned on the support portion 7a. Further, the extending portion 6b is wound from the lower surface side to the upper surface side of the support portion 7a at a position on the receiving portion 8 side with respect to the pressing portion 6a. That is, the front through hole 7a1 of the present embodiment is located on the receiving portion 8 side with respect to the pressing portion 6a. Therefore, in the cross-sectional view shown in FIG. 4, the pressing portion 6a and the extension portion 6b, which constitute the pressing body 6 of the present embodiment, are partially protruded downward due to their stiffness by being wound around the support portion 7a. However, as a whole, it is curved in a substantially U shape. As a result, the expanded portion as the pressing portion 6a can be expanded while rotating the portion of the extending portion 6b connected to the pressing portion 6a as the hinge portion 9. As shown in FIG.

The expansion part as the pressing part 6a can be expanded not only in the thickness direction A but also in a direction inclined with respect to the thickness direction A by rotating with the hinge part 9 of the extension part 6b. As described above, the pressing body 6 of the present embodiment has the sheet-like extension part 6b wound over the upper and lower surfaces of the support part 7a of the support body 7 through the front through hole 7a1 of the support part 7a. , is fixed to the support portion 7a. Therefore, the expanded portion as the pressing portion 6a rotates around the hinge portion 9, which is the portion of the extending portion 6b that is connected to the pressing portion 6a below the front through hole 7a1, when expanded. Expand while rotating around the center of movement.

More specifically, the two

balloon portions

10a and 10b that constitute the expansion portion as the pressing portion 6a of the present embodiment are arranged in a state of being superimposed in the thickness direction A. One end of each of these two

balloon portions

10a and 10b is attached to the extension portion 6b. That is, one end sides of the two

balloon portions

10a and 10b are restrained by the extended portion 6b. Therefore, even if the two

balloon portions

10a and 10b are expanded, the two

balloon portions

10a and 10b are not separated from each other on the one end side. On the other hand, the other end sides of the two

balloon portions

10a and 10b are not constrained at all. Therefore, when the two

balloon portions

10a and 10b are inflated, the two

balloon portions

10a and 10b are separated from each other on the other end side. That is, in the two

balloon portions

10a and 10b that constitute the pressing portion 6a of the present embodiment, the one end side attached to the extension portion 6b is the center of rotation, and the other end side that is not attached to the extension portion 6b is rotated. , rotates around this rotation center. In this manner, the expanded portion as the pressing portion 6a of the present embodiment expands in a direction inclined with respect to the thickness direction A. As shown in FIG. By forming the expanded portion that expands in a direction that is inclined with respect to the thickness direction A, it becomes easier to constrict or block a perforation P (see FIG. 12B), which will be described later. Details of this will be described later (see FIG. 13). However, the configuration for expanding in the direction inclined with respect to the thickness direction A is not limited to the configuration of the pressing body 6 of this embodiment.

The pressing body 6 of this embodiment is made of a translucent member, and can be seen in a direction orthogonal to the sticking surface 2a. The same applies to at least a support portion 7a of a support body 7, which will be described later. Therefore, according to the compression device 1 of the present embodiment, the compression position on the surface of the living body can be visually recognized through the pressing portion 6a and the extension portion 6b of the pressing body 6 and the supporting portion 7a of the supporting body 7. However, like the extended portion 6b of the present embodiment, a visual through-hole 6b2 may be provided in order to make it easier to visually recognize the pressed position on the surface of the living body.

The constituent material of the pressing portion 6a and the extending portion 6b of the pressing body 6 is, for example, soft polyvinyl chloride, polyurethane, polyethylene, polypropylene, polyester, ethylene-vinyl acetate copolymer (EVA), silicone, or among these. Any flexible material mixed with any material can be used.

The support 7 of this embodiment includes a support portion 7a and a grip portion 7b.

The support portion 7a extends from a position overlapping the sticking surface 2a to a position overlapping the pressing portion 6a in plan view. Further, the support portion 7a is fixed to the adhesive body 2 on the fixing surface 2b opposite to the adhesive surface 2a. Further, the support portion 7a supports the pressing portion 6a. In the present embodiment, a portion of the support portion 7a that overlaps the adhesive body 2 in plan view is fixed to the fixing surface 2b of the adhesive body 2 . In the present embodiment, a portion of the support portion 7a that does not overlap the adhesive body 2 in plan view and overlaps the pressing portion 6a supports the pressing portion 6a.

More specifically, the support portion 7a of the present embodiment is fixed to the fixing surface 2b of the adhesive sheet 4, and includes an outer edge portion 11a extending in a substantially C shape in plan view and an inner side of the outer edge portion 11a in plan view. and a central portion 11b located at the

The outer edge portion 11a of the present embodiment extends in a substantially C shape so that substantially the entire area overlaps the adhesive sheet 4 in plan view. The outer edge portion 11a of the present embodiment is fixed to the fixing surface 2b, which is the upper surface of the adhesive sheet 4. As shown in FIG. Both ends of the adhesive sheet 4 and the outer edge portion 11a extending in a substantially C shape in a plan view define a gap therebetween. This gap constitutes a receiving portion 8 of the compression device 1 capable of receiving a medical insertion member that is or is being inserted into the blood vessel BV of the living body (see FIGS. 2 and 3).

Although the receiving portion 8 of the present embodiment is configured by a gap between both ends of the adhesive sheet 4 and the outer edge portion 11a, the configuration of the receiving portion 8 is not particularly limited. The receiving portion 8 may be configured by a concave portion formed in the outer edge of the compression device 1 in plan view.

The central portion 11b of the present embodiment includes a portion of the support portion 7a that overlaps the pressing portion 6a in plan view and supports the pressing portion 6a. The front through hole 7a1 described above is formed in the central portion 11b. Further, the central portion 11b is provided with the locking protrusion 7a2 that fits into the locking hole 6b1 of the extended portion 6b of the pressing body 6. As shown in FIG. The pressing portion 6a of the pressing body 6 described above is arranged on the lower surface side of the central portion 11b.

Thus, in this embodiment, only the lower surface of the outer edge portion 11a of the support portion 7a is fixed to the fixing surface 2b of the adhesive sheet 4, which is substantially C-shaped in plan view. In other words, the lower surface of the central portion 11b of the support portion 7a is not covered with the adhesive sheet 4. As shown in FIG. Therefore, the lower surface of the central portion 11b of the support portion 7a is not fixed to the fixing surface 2b of the adhesive sheet 4. As shown in FIG.

The central portion 11b of the support portion 7a sandwiches the expanded pressing portion 6a with the surface of the living body. Specifically, the central portion 11b of the support portion 7a of the present embodiment includes a portion located above the extended portion as the pressing portion 6a. Therefore, when the pressing portion 6a expands while the sticking surface 2a of the sticking body 2 is stuck to the surface of the living body, the pressing portion 6a is sandwiched from above and below by the central portion 11b of the support portion 7a and the surface of the living body. be As a result, the surface of the living body is pressed by the pressing portion 6a.

The support portion 7a of the present embodiment is flat in the thickness direction A and has a substantially rectangular outer shape when viewed from above, but the shape is not particularly limited. In addition, in the support portion 7a of the present embodiment, the maximum thickness in the thickness direction A is greater at the outer edge portion 11a than at the central portion 11b, but the relationship between the thicknesses is not particularly limited.

Here, as shown in FIGS. 1 to 3, the support portion 7a defines a side through hole 12a and a rear through hole 12b penetrating in the thickness direction A, which is the direction perpendicular to the sticking surface 2a.

Although the details will be described later, the side through hole 12a is positioned between the pressing portion 6a and the side sticking surface 2a1 of the sticking surface 2a in plan view, and penetrates in a direction orthogonal to the sticking surface 2a. means hole. The “lateral sticking surface” refers to a portion of the sticking surface that is stuck to the surface of the living body at a position spaced apart from the pressing portion in the direction perpendicular to the extending direction of the blood vessel on the surface of the living body. means. As shown in FIGS. 2 and 3, the side sticking surfaces 2a1 of the present embodiment are portions located on both sides in the width direction B with respect to the pressing portion 6a. The side opening 50 of this embodiment is configured by the side through hole 12a defined by the support portion 7a.

Further, the rear through-hole 12b means a through-hole penetrating in a direction orthogonal to the sticking surface 2a at a position between the pressing portion 6a and the rear sticking surface 2a2 of the sticking surface 2a in plan view. The “rear attachment surface” means a portion of the attachment surface that is attached to the surface of the living body at a position spaced from the pressing portion in the direction in which the blood vessel extends on the surface of the living body. As shown in FIGS. 2 and 3, the rear adhesive surface 2a2 of the present embodiment is a portion positioned in the rearward direction C2 of the extending direction C with respect to the pressing portion 6a.

The grip portion 7b protrudes in the upward direction A2 from the support portion 7a. Specifically, the grip portion 7b of the present embodiment protrudes in the upward direction A2 from the outer edge portion 11a of the support portion 7a. The grasping portion 7b is grasped by a medical worker. By providing such a grip portion 7b, the compression device 1 becomes easier to hold. Therefore, the operability for medical staff can be improved.

More specifically, the support 7 of this embodiment includes two grips 7b that are arranged to face each other. A medical worker can easily hold the compression device 1 by pinching the two grips 7b arranged facing each other. The two gripping portions 7b of the present embodiment are configured by two gripping plate portions arranged to face each other in the width direction B. As shown in FIG.

Examples of materials for the support 7 of this embodiment include resin materials. Examples of the resin material include ABS resin, AS resin, polyethylene, polypropylene, polystyrene, polyvinyl chloride, polyvinylidene chloride resin, polyphenylene oxide, thermoplastic polyurethane, polymethylene methacrylate, polyoxyethylene, fluororesin, polycarbonate, and polyamide. , acetal resins, acrylic resins, polyethylene terephthalate, and other thermoplastic resins used in injection molding; and phenolic resins, epoxy resins, silicone resins, unsaturated polyesters, and other thermosetting resins.

<<Side opening 50 of compression device 1>>
Next, the details of the side opening 50 of the compression device 1 of this embodiment will be described. As described above, the side opening 50 of the compression device 1 of this embodiment is configured by the side through hole 12a defined by the support portion 7a. In the compression device 1 of this embodiment, a blood removing member 80 (see FIG. 7F) such as a cotton ball or gauze can be pushed through the side through hole 12a as the side opening 50. FIG. As a result, the blood leaking from the wound on the surface of the living body pressed by the pressing portion 6a can be removed.

The side openings 50 of the present embodiment are configured by the side through holes 12a of the support portion 7a located on both sides of the pressing portion 6a in the width direction B in plan view, but are not limited to this configuration. That is, the side opening 50 is provided at a position between the pressing portion 6a and the side sticking surface 2a1 of the sticking surface 2a in a plan view, and the compression device 1 extends in a direction orthogonal to the sticking surface 2a. It is a penetrating opening, and may not be constituted by only the side through-holes 12a of the support portion 7a, and may be configured to include the side through-holes 12a as part thereof. Furthermore, the side opening 50 may not be a hole penetrating through the support portion 7a, and may be configured by, for example, a concave portion such as a notch provided in the outer edge of the support portion 7a in plan view. However, as in the present embodiment, by forming the side opening 50 with the side through hole 12a of the support portion 7a, the shape stability of the support portion 7a is improved compared to the case of forming the above-described concave portion. be able to.

Further, as shown in FIG. 2, in plan view, the side outer edge of the pressing portion 6a in the width direction B in plan view overlaps the side through hole 12a defined by the support portion 7a. In other words, in the top view shown in FIG. 2, the side outer edge of the pressing portion 6a enters the side through hole 12a so as to be visible through the side through hole 12a. However, the pressing portion 6a does not cover the entire area below the side through hole 12a. That is, in the present embodiment, a portion of the side through-hole 12a that does not overlap the pressing portion 6a in the thickness direction A, which is a direction orthogonal to the sticking surface 2a, constitutes the side opening 50. As shown in FIG.

By providing the side through-hole 12a so that the side outer edge of the pressing portion 6a enters the lower side of the side through-hole 12a in this way, the position adjacent to the pressing portion 6a can be reached through the side through-hole 12a. , a blood removal member 80 (see FIG. 7F), such as a cotton ball, can be pushed. Therefore, it is possible to easily remove the blood that accumulates on the surface of the living body or adheres to the surface of the living body at a position adjacent to the pressing portion 6a.

In addition, as shown in FIG. 2, the side opening 50 is provided at least at a position outside in the width direction B with respect to the central position M in the extending direction C of the pressing portion 6a in plan view. preferable. By doing so, it becomes easier to arrange the side opening 50 in the vicinity of the wound on the surface of the living body to be pressed by the pressing portion 6a. In particular, as shown in FIG. 2, the side opening 50 is preferably provided at a position outside in the width direction B with respect to the entire area of the central area N of the pressing portion 6a in plan view. Here, the “central area N of the pressing portion 6a” means a 50% area centered at the central position M of the pressing portion 6a with respect to the entire area in the extending direction C of the pressing portion 6a. By doing so, it becomes easier to arrange the side opening 50 in the vicinity of the wound on the surface of the living body to be pressed by the pressing portion 6a.

Further, as shown in FIG. 2, the side openings 50 are provided so as to be positioned outside in the width direction B with respect to 70% or more of the entire area in the extending direction C of the pressing portion 6a. preferably. By doing so, it becomes easier to arrange the side opening 50 in the vicinity of the wound on the surface of the living body to be pressed by the pressing portion 6a. More preferably, the side opening 50 is provided so as to be positioned outside in the width direction B with respect to 80% or more of the entire area in the extending direction C of the pressing portion 6a.

<<Rear opening 51 of compression device 1>>
Furthermore, the compression device 1 of this embodiment defines a rear opening 51 in addition to the side openings 50 described above. As shown in FIGS. 2 and 3, the rear opening 51 penetrates in a direction orthogonal to the sticking surface 2a at a position between the pressing portion 6a and the rear sticking surface 2a2 of the sticking surface 2a in plan view. It is an opening. The rear opening 51 of the present embodiment is configured by the rear through hole 12b defined by the support portion 7a, but the configuration is not particularly limited. The rear opening 51 may be an opening penetrating the compression device 1 in a direction orthogonal to the sticking surface 2a at a position between the pressing portion 6a and the rear sticking surface 2a2 in plan view.

Since the compression device 1 defines the rear opening 51 , a blood removal member 80 such as a cotton ball (see FIG. 7F) can be pushed through the rear opening 51 in addition to the side opening 50 . Therefore, the blood leaking from the wound on the surface of the living body pressed by the pressing portion 6a can be more reliably removed.

<<Method of Compressing Living Body Using Compression Device 1>>
Next, a method for compressing a living body surface using the compression device 1 according to the present disclosure will be described. FIG. 6 is a flow chart showing an example of a method for compressing the surface of a living body using the compression device 1. As shown in FIG. The body compression method shown in FIG. 6 includes a sticking step S1, a first compression step S2, a withdrawal step S3, a second compression step S4, a blood removal step S5, and a removal step S6. 7A and 7B are diagrams showing an outline of the sticking step S1. FIG. 7C is a diagram showing an outline of the first compression step S2. FIG. 7D is a diagram showing an overview of the removal step S3. FIG. 7E is a diagram showing an outline of the second compression step S4. FIG. 7F is a diagram showing an outline of the blood removal step S5.

The biological compression method illustrated in FIGS. 6 and 7A to 7F is a biological compression method that compresses the biological surface BS to constrict or occlude perforations leading from the biological surface to the veins without occluding the veins. be. The perforation is formed by removing the sheath as the medical insertion member 100 inserted into a vein such as a femoral vein from the body surface BS through the connective tissue. Hemostasis after removing the sheath as the medical insertion member 100 can be performed by the living body compression method shown here. First, the perforation formed after removing the medical insertion member 100 will be described with reference to FIGS. 12A and 12B. FIG. 12A shows a state in which the sheath as the medical insertion member 100 is inserted into the femoral vein FV from the body surface BS through the connective tissue CT. In FIG. 12A, three sheaths are shown as the medical insertion member 100, but the number may be two or less, or four or more. FIG. 12B shows the state after removing the sheath as the medical insertion member 100 from the state shown in FIG. 12A. As shown in FIG. 12B, by removing the sheath as the medical insertion member 100, a perforation P is formed between the body surface BS and the femoral vein FV. 6 and 7A-7F, the perforation P can be constricted or occluded without occluding the femoral vein FV. Therefore, even in the case of stopping bleeding from a vein located deep from the surface of a living body, the vein itself does not need to be constricted or occluded, and the bleeding can be stopped more efficiently. The details of each step S1 to S6 will be described below with reference to FIGS. 7A to 7F.

FIG. 7A shows a state in which a sheath as the medical insertion member 100 is inserted from the body surface BS into the femoral vein FV (see FIGS. 12A and 12B). FIG. 7B shows a state in which the compression device 1 has been attached to a predetermined position on the living body surface BS while the sheath as the medical insertion member 100 is inserted into the living body. FIG. 7A shows a pre-use state in which the sticking surface 2a is covered with a liner 70. FIG. On the other hand, FIG. 7B shows the state of use after the liner 70 has been peeled off from the sticking surface 2a.

As shown in FIGS. 7A and 7B, the compression device 1 is attached to the surface of the living body by attaching the sticking surface 2a of the sticking sheet 4 as the sticking body 2 to the surface of the living body. Specifically, as shown in FIG. 7B, the receiving portion 8 receives the portion of the sheath as the medical insertion member 100 inserted into the living body through the living body surface BS, which is exposed to the outside from the living body surface BS. Then, the sticking surface 2a is stuck to the living body surface BS.

Next, as shown in FIG. 7C, a syringe 30 as a fluid supply device is connected to the connecting portion 29 of the tube 28 . Air is supplied through the tube 28 to the accommodation space 6a1 (see FIG. 5) of the expanded portion as the pressing portion 6a (see FIG. 5) of the compression device 1 to expand the pressing portion 6a. By doing so, the vicinity of the wound on the body surface BS can be pressed in advance before the sheath as the medical insertion member 100 is removed from the body surface BS. In other words, the sheath as the medical insertion member 100 is inserted into the femoral vein FV as a vein from the body surface BS through the connective tissue CT (see FIGS. 12A and 12B), and the pressure on the body surface BS is started. do. In this manner, the medical insertion member 100 is compressed before being removed from the biological surface BS. As a result, the living body surface BS can be pressed immediately after the sheath as the medical insertion member 100 is removed. Therefore, the perforation P (see FIG. 12B) extending from the body surface BS to the femoral vein FV (see FIGS. 12A and 12B) can be constricted or occluded immediately after removal of the sheath.

Next, as shown in FIG. 7D, the sheath as the medical insertion member 100 is removed from the living body surface BS. By removing the sheath, a perforation P shown in FIG. 12B is formed. If the living body surface BS is not pressed at all in this state, the femoral vein FV will bleed outside the living body through the perforation P and the wound on the living body surface BS. However, in the living body pressing method shown here, the living body surface BS is pressed in advance before the sheath as the medical insertion member 100 is removed from the living body surface BS, as shown in FIG. 7C. Therefore, immediately after the sheath is removed, the body surface BS can be compressed so as to constrict or block the perforation P (see FIG. 12B), and the amount of bleeding immediately after the sheath is removed can be suppressed.

Next, as shown in FIG. 7E, the syringe 30 as a fluid supply device is reconnected to the connecting portion 29 of the tube 28 . Through the tube 28, the housing space 6a1 (see FIG. 5) of the pressing portion 6a (see FIG. 5) of the compression device 1 is pressurized by supplying air again, or decompressed by removing the air. In other words, after the sheath as the medical insertion member 100 is removed, the compressive force on the body surface BS is adjusted. By adjusting the compressive force on the body surface BS, the perforation P (see FIG. 12B) is further constricted or occluded without occluding the femoral vein FV (see FIGS. 12A and 12B), thereby reducing the amount of bleeding. It can greatly reduce or stop bleeding.

More specifically, if bleeding is confirmed after removing the sheath, apply pressure by slowly increasing the pressure until hemostasis is achieved. On the other hand, when hemostasis is confirmed after removing the sheath, the pressure is slowly reduced until bleeding is confirmed. Then, after bleeding is confirmed, the pressure is slowly increased until hemostasis is achieved. By doing so, it is possible to prevent occlusion of the femoral vein FV (see FIGS. 12A and 12B) due to excessive pressurization.

In addition, an ultrasonic device may be used to detect whether or not the body surface BS is appropriately compressed. Specifically, the pressing body 6 and the support body 7 are formed of a material having ultrasonic wave permeability, and a fluid having ultrasonic wave permeability such as water is supplied to the pressing portion 6a of the pressing body 6. , the state of compression by the compression device 1 can be diagnosed by ultrasound. That is, it is possible to detect whether or not the femoral vein FV (see FIGS. 12A and 12B) is occluded by the ultrasonic device. The compression force of the compression device 1 may be adjusted based on the diagnostic results obtained by the ultrasonic device.

Hemostasis can be completed by maintaining the compressed state for several hours (for example, 2 to 6 hours). During hemostasis, blood may leak through the perforations P (see FIG. 12B) when the position of the compression device 1 is displaced due to body movement of the patient or the like. In such a case, as shown in FIG. 7F, a blood removing member 80 such as a cotton ball is inserted through the side opening 50 to the side of the pressing portion 6a. This allows the leaked blood to be removed. Also, the blood removing member 80 may be inserted not only through the side opening 50 but also through the rear opening 51 . Additionally, the blood removal member 80 may be inserted from the receptacle 8 . After hemostasis is completed, the pressure device 1 is removed from the living body surface BS by peeling the sticking surface 2a of the sticking body 2 from the living body surface BS.

As described above, the biocompression method presented here constricts or occludes the perforation P (see FIG. 12B) without occluding the femoral vein FV (see FIGS. 12A and 12B). In the case of venous hemostasis, hemostasis can be achieved by constriction or occlusion of the perforation P (see FIG. 12B). On the other hand, for example, in the case of hemostasis of the femoral artery, even if only the perforation is closed, the blood leaks and spreads in the connective tissue CT (see FIGS. 12A and 12B), so the hemostasis cannot be achieved. In the case of hemostasis of the femoral artery, large-scale countermeasures are required, such as a method of compressing the artery so strongly as to constrict or block the artery itself, a method of closing a hole in the artery wall, and the like.

Therefore, in the above-described method of compressing the body, it is preferable to compress the body surface BS to a position where the compression depth from the body surface BS is 5 mm to 20 mm. By setting the compression depth within the above range, it is easy to achieve a compressed state in which the perforation P (see FIG. 12B) is constricted or occluded without occluding the vein. The compression depth is more preferably 5 mm to 15 mm, even more preferably 8 mm to 12 mm.

Furthermore, in the above-described method of pressing a living body, it is preferable to press the living body surface BS from 10 g/cm ² to 600 g/cm ² from the living body surface BS. This compressive pressure is the pressure after the sheath as the medical insertion member 100 is removed, and does not mean the compressive force before the sheath is removed as described above. By setting the compressive pressure within the above range, it is easy to realize a compressed state in which the perforation P (see FIG. 12B) is constricted or occluded without occluding the vein. The compressing pressure is more preferably 50 g/cm ² to 400 g/cm ² , still more preferably 100 g/cm ² to 300 g/cm ² .

Moreover, it is preferable to press the body surface BS along a direction orthogonal to the extending direction of the perforations P (see FIG. 12B). "Applying along the direction perpendicular to the extending direction of the perforation" is not limited to applying pressure only in the direction perpendicular to the extending direction of the perforation. It also means pressing in a direction that is inclined at a predetermined angle or less (for example, 30 degrees or less) with respect to the direction in which it is. The compression device 1 of this embodiment can compress the body surface BS along the direction orthogonal to the extending direction of the perforations P (see FIG. 12B).

Specifically, the extension portion as the pressing portion 6a of the present embodiment can be extended in a direction inclined with respect to the thickness direction A, as described above. By doing so, the living body surface can be pressed along the direction orthogonal to the extending direction of the perforations P (see FIG. 12B). Specifically, as shown in FIGS. 12A and 12B, the sheath as the medical insertion member 100 is not perpendicular to the surface of the body BS (the same direction as the thickness direction A), but the surface of the body BS. It is inserted in a direction inclined to one side with respect to the orthogonal direction. Therefore, as shown in FIG. 12B, the extending direction of the perforations P is also inclined with respect to the direction perpendicular to the body surface BS. Therefore, the direction inclined opposite to the extending direction of the perforations P with respect to the thickness direction A, which is the direction orthogonal to the biological surface BS (hereinafter, may be referred to as the "tilt direction F"). If the pressing portion 6a is expandable, it becomes easier to press the body surface BS along the direction orthogonal to the extending direction of the perforation P. This facilitates realization of the compression device 1 that narrows or closes the perforation P without closing a vein such as the femoral vein FV in FIGS. 12A and 12B. FIG. 13 shows a state in which the compression device 1 narrows or closes the perforation P shown in FIG. 12B. As shown in FIG. 13, according to the compression device 1, the perforation P can be more easily constricted or occluded without occluding a vein such as the femoral vein FV.

According to the biological compression method shown in FIGS. 6 and 7A to 7F, hemostasis can be achieved by constricting or closing the perforation P (see FIG. 12B) without closing the vein such as the femoral vein FV. can. In particular, by realizing the above-described method of compressing a living body using the compression device 1, it is possible to eliminate the need for manual compression by medical personnel and the use of large-scale hemostatic instruments, and to stop bleeding in a simple manner.

<<Compression to the surface of the living body by the compression device 1>>
As shown in FIG. 13, in the compression device 1, the expanded portion as the pressing portion 6a of the compression member 3 extends in a vertical direction (FIG. 13 , which is the same direction as the thickness direction A, and can press the surface of the living body toward an inclination direction F that is inclined with respect to the vertical direction in FIG. By doing so, as shown in FIG. 13, the perforation P can be easily constricted or occluded without occluding a vein such as the femoral vein FV.

FIG. 14 is a front view of the state shown in FIG. 13, viewed from the living body surface BS side. In other words, FIG. 14 shows a front view of the body surface BS at a position compressed by the compression device 1 . Here, "a front view of the surface of the living body at the position compressed by the compression device" means that the part of the surface of the living body to be compressed by the compression device is perpendicular to the part before compression. It means the state seen from the direction. FIG. 14 shows a front view of the groin. In the front view shown in FIG. 14, the direction in which the body surface BS is pressed (see the white arrow “AR1” in FIG. 14) is the insertion direction of the sheath from the body surface BS toward the vein in the extending direction G of the perforation P. It faces G1 (see white arrow “AR2” in FIG. 14). That is, the direction in which the compression device 1 compresses the body surface BS is opposite to the insertion direction G1 of the sheath in the front view shown in FIG. By doing so, the perforation P (see FIGS. 12B and 13) can be easily constricted or occluded without occluding a vein such as the femoral vein FV.

In other words, as shown in FIG. 13, the extending direction G of the perforations P is inclined with respect to the living body surface BS, and is perpendicular to the living body surface BS (vertical direction in FIG. 13). is also slanted. Further, as shown in FIG. 13, the direction in which the body surface BS is compressed by the compression device 1 is also inclined with respect to the body surface BS and is a vertical direction perpendicular to the body surface BS (vertical direction in FIG. 13). is also inclined with respect to Furthermore, as shown in FIG. 13, the extending direction G of the perforations P is on the side opposite to the inclination direction F as the direction of compression of the body surface by the compression device 1 with respect to the vertical direction (vertical direction in FIG. 13). leaning toward That is, the compression device 1 compresses the surface of the living body so that the direction of compression intersects with the extending direction G of the perforation P. As shown in FIG. Thereby, the perforation P can be efficiently constricted or occluded.

As shown in FIG. 9(a), the side outer edge of the pressing portion 6a of the present embodiment does not overlap the side through hole 112a defined by the support portion 107a as the side opening 50 in plan view. In other words, the side through holes 112a of the present embodiment are formed only at positions outside in the width direction B from the pressing portion 6a. As shown in FIGS. 9B and 10, the support portion 107a of the present embodiment is positioned between the side through-hole 112a and the pressing portion 6a in a plan view, and is positioned closer to the attachment surface 2a than the attachment surface 2a. It has a protruding convex portion 60 . That is, the convex portion 60 is provided in the width direction B between the side through hole 112a and the pressing portion 6a. The convex portion 60 protrudes downward from the sticking surface 2a.

With such a configuration, as shown in FIG. It is easy to get caught on the convex portion 60 at a position between the pressing portion 6a. Therefore, it is possible to prevent the blood removing member 80 such as a cotton ball pushed through the side through-hole 112a as the side opening 50 from unintentionally falling out of the side through-hole 112a. Therefore, it becomes easier to maintain the position of the blood removing member 80 in the vicinity of the pressing portion 6a.

More specifically, in this embodiment, the side through holes 112a are defined in the central portion 111b of the support portion 107a. The side through holes 112a are provided on both sides in the width direction B with respect to the pressing portion 6a. Further, the central portion 111b of the support portion 107a of the present embodiment defines not only the side through holes 112a but also the rear through holes 12b as the rear openings 51. As shown in FIG.

In addition, the convex portion 60 of the present embodiment continuously protrudes downward from the inner surface defining the side through hole 112a. However, the position of the convex portion 60 is not limited to the position of the present embodiment. The convex portion 60 may be positioned at a position different from that of the present embodiment as long as it is positioned between the side through-hole 112a and the pressing portion 6a in plan view.

Further, the support portion 107a may have a projection projecting from the sticking surface 2a at a position between the rear through-hole 12b and the pressing portion 6a in plan view. By providing such a convex portion, it is possible to prevent the blood removal member 80 pushed through the rear through-hole 12b from coming off.

Furthermore, although the convex portion 60 of the present embodiment is a rib-like convex portion extending in the extension direction C, it is not limited to this configuration. The convex portion 60 may be, for example, a columnar, conical, or frustum-shaped protrusion. Further, a plurality of protrusions 60 may be provided between the lateral through hole 112a in the width direction B and the pressing portion 6a. Furthermore, a plurality of protrusions 60 may be provided in the extending direction C. As shown in FIG.

As shown in FIGS. 8, 10, and 11, the grip portion 7b of the support 107 may define an insertion hole 7b1 penetrating in the width direction B. By providing such an insertion hole 7b1, for example, a long body such as a belt-like member can be inserted through the insertion hole 7b1. By winding and fixing the elongated body inserted through the insertion hole 7b1 around the living body, the compression device 1 adhered to the living body surface by the sticking surface 2a can be attached to the living body surface such as a curved portion on the living body surface, for example. It becomes easy to maintain the shape along the Thereby, unintentional detachment of the sticking surface 2a from the biological surface can be suppressed. In addition, it is possible to prevent the skin from being pulled by the force that tends to separate the sticking surface 2a from the surface of the living body. Therefore, the patient's pain can be reduced.

The compression device according to the present disclosure is not limited to the specific configurations shown in the above-described embodiments, and various modifications and changes are possible without departing from the scope of the claims.

The present disclosure relates to compression devices.
