[First Embodiment]
1 to 6 are diagrams showing a compression device 1 as an embodiment of the present disclosure. Specifically, FIG. 1 is a perspective view of the compression device 1 as viewed from the upper surface side. 2 and 3 are plan views of the compression device 1. Specifically, FIG. 2 is a top view of the compression device 1. FIG. 3 is a bottom view of the compression device 1. FIG. 4 is an exploded perspective view of the compression device 1. 5 and 6 are cross-sectional views of the compression device 1 in the same cross section. Details will be described later, but FIGS. 5 and 6 show different states of the compression device 1.

The compression device 1 includes a sticking sheet 2 and a compression member 3.

The sticking sheet 2 is provided with a sticking surface 11 that can be stuck to the surface of the living body on one side in the thickness direction A. The compression member 3 is attached to the sticking sheet 2. Specifically, the compression member 3 is fixed to the sticking sheet 2 on the side opposite to the sticking surface 11. The compression member 3 can press the surface of the living body in a state where the sticking surface 11 is attached to the surface of the living body. In this way, the position of the compression device 1 on the surface of the living body is fixed by sticking the sticking surface 11 to the surface of the living body. According to the compression device 1, the compression member 3 can press a predetermined portion on the surface of the living body in a state where the sticking surface 11 of the sticking sheet 2 is stuck on the surface of the living body. The predetermined site on the surface of the living body includes, for example, a wound on the surface of the living body or a vicinity thereof formed by inserting a medical insertion member such as a puncture needle, a catheter, or a sheath into a blood vessel of the living body. After removing the above-mentioned medical insertion member from the living body, bleeding can be stopped by pressing the wound on the surface of the living body or its vicinity with the pressing member 3 for a predetermined time.

More specifically, the compression member 3 includes a pressing body 4 and a holding body 5. The pressing body 4 can press the surface of the living body by extending in the thickness direction A of the sticking sheet 2. The holding body 5 is fixed to the sticking sheet 2 on the side opposite to the sticking surface 11, and holds the pressing body 4 so as to be extendable in the thickness direction A.

The holding body 5 includes a line segment marker 7a extending in an arc shape at a position overlapping the pressing body 4 in a plan view of the compression device 1 in the thickness direction A.

The configuration of the line segment marker 7a is not particularly limited as long as it can be visually identified that the compression device 1 extends in an arc shape in a plan view viewed in the thickness direction A. The line segment marker 7a may be composed of, for example, one rib-shaped convex portion protruding from the upper surface of the holding body 5. Further, the line segment marker 7a has, for example, a plurality of convex portions arranged in a line at intervals so that the compression device 1 has a broken line shape extending in an arc shape as a whole in a plan view in the thickness direction A. It may be an aspect of forming a line segment. Further, the line segment marker 7a may be formed of, for example, a recess such as a groove formed on the upper surface of the holding body 5. Further, the above-mentioned convex portion or concave portion constituting the line segment marker 7a is not limited to the upper surface of the holding body 5, and may be provided on the lower surface of the holding body 5. In such a case, in order to make the convex portion or the concave portion provided on the lower surface of the holding body 5 visible from the top view (see FIG. 2), the position where the convex portion or the concave portion is provided on the upper surface view of the holding body 5. Is configured to have translucency in the thickness direction A from at least the upper surface to the lower surface. Here, "having translucency in the thickness direction A" means that it is translucent or transparent in the thickness direction A. Further, the line segment marker 7a may be configured, for example, by making the transmittance different from that of the surroundings. As an example of this, the line segment marker 7a may be composed of a portion having a lower transmittance than the surroundings, which is located in the translucent portion of the holding body 5. In addition to this, the line segment marker 7a may be configured, for example, by making the color different from the surroundings. Such a line segment marker 7a may be composed of, for example, a paint forming a part of the upper surface or the lower surface of the holding body 5. In this way, the line segment marker 7a can be identified as a line segment extending in an arc shape, distinguishing from the surroundings, in a plan view under the usage environment of the compression device 1, particularly a top view (see FIG. 2). It is not particularly limited as long as it is an embodiment.

By providing such a line segment marker 7a, the biological surface of the medical insertion member 100 is provided regardless of the outer diameter of the medical insertion member 100 (see FIG. 8A) inserted into the living body from the surface of the living body. A part (for example, a part of the outer surface) of the insertion portion 100a (see FIG. 8A) located on the same plane as the above is in contact with the line segment marker 7a in the plan view of the compression device 1 in the thickness direction A. Can be aligned so that they overlap. That is, the line segment marker 7a does not partition a predetermined closed region in a plan view of the compression device 1 in the thickness direction A. Therefore, regardless of the outer diameter of the medical insertion member 100, only a part of the insertion portion 100a of the medical insertion member 100 can be used to align the line segment marker 7a. In other words, according to the line segment marker 7a, the medical staff is asked to align the medical insertion member 100 at a predetermined position by using a part of the insertion portion 100a regardless of its outer diameter. Can be guided. As a result, it is possible to prevent the mounting position of the compression device 1 from fluctuating on the surface of the living body due to the difference in the outer diameter of the medical insertion member 100. As a result, the compression device 1 that can be easily positioned at an appropriate position on the surface of the living body can be realized regardless of the difference in the outer diameter of the medical insertion member 100. Details of positioning the insertion portion 100a of the medical insertion member 100 with respect to the line segment marker 7a will be described later (see FIGS. 8A and 8B).

In particular, the line segment marker 7a is curved and extends in an arc shape in a plan view of the compression device 1 in the thickness direction A. Therefore, the compression device 1 is aligned so that a part of the outer surface of the insertion portion 100a (see FIG. 8A) extending in a convex and arc shape in a plan view in the thickness direction A is inserted into the concave portion of the line segment marker. It will be easier.

Further, in a plan view of the compression device 1 in the thickness direction A (see FIGS. 2 and 3), the area where the attachment sheet 2 is not arranged is outside the outer edge of the holding body 5, and is a medical treatment described later. A receiving portion 6 capable of receiving the insertion member 100 (see FIG. 8A and the like) is provided. More specifically, the sticking sheet 2 of the present embodiment has a first portion X1 that overlaps with the holding body 5 and a holding body in a plan view (see FIGS. 2 and 3) in which the compression device 1 is viewed in the thickness direction A. A second portion X2 that does not overlap with 5 is provided. As shown in FIG. 2, in the top view of the compression device 1, most of the outer periphery of the outer edge of the holding body 5 of the present embodiment is surrounded by the second portion X2 of the sticking sheet 2. In other words, the outer edge of the holding body 5 of the compression device 1 of the present embodiment has only a part of the outer edge of the holding body 5 in which the second portion X2 of the sticking sheet 2 is not arranged. The receiving portion 6 of the present embodiment is composed of a region around the holding body 5 in which the second portion X2 of the sticking sheet 2 is not arranged.

The receiving portion 6 of the present embodiment has a region in which the sticking sheet 2 is not arranged on the outside of the outer edge of the holding body 5 in a plan view (see FIGS. 2 and 3) of the compression device 1 in the thickness direction A. It is configured, but is not limited to this configuration. The receiving portion 6 may be an area partitioned by a recess on the outer edge of the sticking sheet 2. For example, in a plan view (see FIGS. 2 and 3) of the compression device 1 viewed in the thickness direction A, a recess outside the outer edge of the holding body 5 and a part of the outer edge of the sticking sheet 2 is recessed from the periphery. May be formed. In such a case, the receiving portion 6 may be a region partitioned by the recess. That is, the receiving portion 6 is formed in a region where the sticking sheet 2 is arranged on the outside of the outer edge of the holding body 5 in a plan view (see FIGS. 2 and 3) when the compression device 1 is viewed in the thickness direction A. You may be. In other words, the position where the receiving portion 6 is formed is such that the sticking sheet 2 is arranged outside the outer edge of the holding body 5 in a plan view (see FIGS. 2 and 3) when the compression device 1 is viewed in the thickness direction A. It is not limited to the area that is not.

Further, although the compression device 1 of the present embodiment is provided with the above-mentioned receiving unit 6, it may be a compression device that does not have the receiving unit 6. However, by providing the receiving portion 6, the compression device 1 is arranged so that the portion of the medical insertion member 100 (see FIG. 8A or the like) extending outside the living body passes through the receiving portion 6. It can be attached to the surface of a living body. As a result, the compression device 1 can be easily attached to a desired position on the surface of the living body even if there is a portion of the medical insertion member 100 (see FIG. 8A or the like) extending outside the living body.

The line segment marker 7a of the present embodiment is provided on the side where the expansion portion 8 described later of the pressing body 4 is located with respect to the receiving portion 6 in the plan view of the compression device 1 in the thickness direction A. Further, the line segment marker 7a is curved convexly from the position of the receiving portion 6 toward the position of the expanding portion 8 in a plan view of the compression device 1 in the thickness direction A. Further, in the present embodiment, the maximum width of the line segment marker 7a is smaller than the maximum width of the expansion portion 8 described later of the pressing body 4 in the plan view of the compression device 1 in the thickness direction A. The maximum width of the line segment marker 7a of the present embodiment means the maximum width of the line segment marker 7a in the width direction B as shown in FIG. Further, the maximum width of the expansion portion 8 of the present embodiment means the maximum width of the expansion portion 8 in the width direction B as shown in FIG. The width direction B means a direction orthogonal to the arrangement direction C in which the receiving portion 6 and the expanding portion 8 of the pressing body 4 are arranged in a plan view of the compression device 1 in the thickness direction A. ..

Further, in the present embodiment, the maximum width of the line segment marker 7a is smaller than the minimum width of the receiving portion 6 in the plan view of the compression device 1 in the thickness direction A. The minimum width of the receiving portion 6 means the minimum width of the receiving portion 6 in the width direction B as shown in FIG.

Although details will be described later, the holding body 5 of the present embodiment includes a border marker 7b1 as a region marker 7b in addition to the line segment marker 7a. The frame line marker 7b1 as the area marker 7b of the present embodiment partitions a predetermined area surrounding the line segment marker 7a in a plan view seen in the thickness direction A of the compression device 1. The frame line marker 7b1 as the region marker 7b of the present embodiment is located on the side where the expansion portion 8 described later of the pressing body 4 is located with respect to the receiving portion 6 in a plan view of the compression device 1 in the thickness direction A. It is provided adjacently. Further, in the present embodiment, the maximum width of the frame line marker 7b1 as the region marker 7b is smaller than the maximum width of the expansion portion 8 described later of the pressing body 4 in the plan view of the compression device 1 in the thickness direction A. .. Further, in the present embodiment, the maximum width of the border marker 7b1 as the region marker 7b is smaller than the minimum width of the receiving portion 6 in the plan view of the compression device 1 in the thickness direction A. Details of the line segment marker 7a and the frame line marker 7b1 as the area marker 7b of the present embodiment will be described later.

Hereinafter, details of each member and each part of the compression device 1 of the present embodiment will be described.

<Attachment sheet 2>
As described above, the sticking sheet 2 includes a sticking surface 11 on one side in the thickness direction A. Further, the sticking sheet 2 includes a mounting surface 12 to which the compression member 3 is mounted on the other side in the thickness direction A, that is, on the side opposite to the sticking surface 11. The sticking sheet 2 has flexibility. Therefore, the sticking sheet 2 can be deformed along the shape of the surface of the living body. In addition, the sticking surface 11 can easily follow the deformation of the living body surface. As a result, it is possible to prevent the compression device 1 from unintentionally peeling from the surface of the living body.

More specifically, the sticking surface 11 of the sticking sheet 2 of the present embodiment is composed of the lower surface of the sticking sheet 2. Further, the mounting surface 12 of the sticking sheet 2 of the present embodiment is composed of the upper surface of the sticking sheet 2.

Hereinafter, for convenience of explanation, one side of the thickness direction A, which is the direction from the mounting surface 12 to the attachment surface 11 in the thickness direction A, may be simply referred to as "downward A1" or "lower side". Further, for convenience of explanation, the other side of the thickness direction A, which is the direction from the sticking surface 11 to the mounting surface 12 in the thickness direction A, may be simply described as "upward direction A2" or "upper side". Further, of the plan view (see FIGS. 2 and 3) of the compression device 1 viewed along the thickness direction A of the sticking sheet 2, the plan view of the sticking sheet 2 seen from the mounting surface 12 side (FIG. 2). (See) is simply referred to as "top view" for convenience of description. Further, of the plan view (see FIGS. 2 and 3) of the compression device 1 viewed along the thickness direction A of the sticking sheet 2, the plan view of the sticking sheet 2 seen from the sticking surface 11 side (FIG. 2). 3) is simply referred to as "bottom view" for convenience of explanation. Further, when the top view and the bottom view are not distinguished, it may be simply described as "plan view". Further, unless otherwise specified, the terms "planar view", "top view", and "bottom view" are used when the expansion portion 8 of the pressing body 4 described later of the compression member 3 is in a contracted form. Means plan view, top view, and bottom view.

The sticking sheet 2 is composed of, for example, a plurality of layers including 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 material layer is made of, for example, a white spunlace non-woven fabric of polyester fibers, and the thickness thereof is in the range of 5 μm to 150 μm, for example, 30 μm. However, the material of the base material layer is not limited to polyester, and for example, an acrylic polymer, polyethylene, an ethylene-vinyl acetate copolymer, polyurethane, a polyamide derivative, or the like may be used.

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 directly to the base material layer or indirectly with another layer in between. The sticking surface 11 of the sticking sheet 2 of the present embodiment is composed of an adhesive layer.

The sticking sheet 2 may include yet another layer in addition to the above-mentioned base material layer and adhesive layer. The sticking sheet 2 may include, for example, a surface layer. The surface layer is composed of, for example, a resin having a thickness of about 5 μm to 50 μm. More specifically, as the material of the surface layer, polyester, polyamide, polyamideimide, polyethylene, polypropylene, polycarbonate, polyurethane, polyvinyl chloride, fluororesin and the like can be used. The surface layer is laminated on the opposite side of the base material layer from the adhesive layer, either directly or indirectly with another layer in between. Therefore, the mounting surface 12 of the sticking sheet 2 may be composed of a surface layer.

More specifically, the sticking sheet 2 may be made of a non-woven fabric tape having an adhesive as an adhesive on one surface. Further, the sticking sheet 2 may be composed of a double-sided tape in which adhesive layers are provided on both sides of the base material layer. When the sticking sheet 2 is made of double-sided tape, the pressing member 3 can be fixed to the sticking sheet 2 by adhering the holding body 5 of the pressing member 3 to one adhesive layer of the sticking sheet. can.

The sticking sheet 2 of the present embodiment has a substantially C-shaped outer shape in a plan view seen in the thickness direction A. As shown in FIGS. 2 and 3, the sticking sheet 2 of the present embodiment covers only a part of the lower surface side of the compression member 3. Specifically, the sticking sheet 2 of the present embodiment covers only the outer edge region of the lower surface of the compression member 3. The sticking sheet 2 of the present embodiment is fixed only to the outer edge region of the lower surface of the compression member 3. In other words, the sticking sheet 2 of the present embodiment does not cover the central region of the lower surface of the pressing member 3 where the expansion portion 8 of the pressing body 4 of the pressing member 3 is located. Further, the sticking sheet 2 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 sticking sheet 2 of the present embodiment does not cover a part of the outer edge region of the lower surface of the compression member 3. In the present embodiment, a portion of the outer edge region of the lower surface of the compression member 3 that is not covered by the sticking sheet 2 is a portion adjacent to the receiving portion 6 of the compression member 3.

The sticking surface 11 of the sticking sheet 2 is covered with the release sheet in the state before use before being stuck to the surface of the living body. The release sheet is removed by being peeled from the attachment surface 11 by the user when the attachment sheet 2 is attached to the surface of the living body. When the release sheet is removed from the attachment surface 11 and the attachment surface 11 is exposed, the attachment surface 11 of the attachment sheet 2 can be attached to the surface of the living body (hereinafter, for convenience of explanation, "use state"). It will be described.) The release sheet can be formed of, for example, a release paper or a sheet material made of resin. The compression device 1 shown in FIGS. 1 to 6 shows a state of use in which the release sheet has been removed.

<Compression member 3>
As described above, the compression member 3 includes a pressing body 4 and a holding body 5.

As described above, the pressing body 4 can press the surface of the living body by extending in the thickness direction A. The pressing body 4 can press the surface of the living body at a position where the sticking sheet 2 is not present in a plan view. That is, the pressing body 4 can press the surface of the living body without passing through the sticking sheet 2.

The pressing body 4 of the present embodiment includes an expansion portion 8 and an extension portion 9. The expansion unit 8 has the living body surface and the holding body 5 in a state where the sticking surface 11 of the sticking sheet 2 is stuck to the living body surface (hereinafter, referred to as “the sticking state of the compression device 1”). Placed in between. The expansion portion 8 can be expanded in the thickness direction A by supplying a fluid while the compression device 1 is attached. That is, the pressing body 4 of the present embodiment extends in the thickness direction A when the expansion portion 8 expands in the thickness direction A. When the expansion unit 8 expands while the compression device 1 is attached, the expansion unit 8 presses the surface of the living body by receiving a reaction force from the holding body 5. Hereinafter, the form before the expansion portion 8 is expanded will be referred to as a “contracted form” of the expansion portion 8. Further, the form in which the expansion portion 8 is expanded from the contracted form is described as the "expansion form" of the expansion portion 8. The compression device 1 of the present embodiment does not press the surface of the living body by the expansion portion 8 when the expansion portion 8 is in the contracted state in the attached state. On the contrary, in the compression device 1 of the present embodiment, when the expansion portion 8 is in the expansion form in the attached state, the expansion portion 8 presses the surface of the living body. FIG. 5 shows a contracted form of the expansion portion 8. FIG. 6 shows an expanded form of the expansion unit 8.

The expansion unit 8 of the present embodiment partitions an accommodation space 8a capable of accommodating a fluid such as a gas inside. Further, the expansion portion 8 of the present embodiment is composed of two

balloon portions

8b and 8c connected so that the inside communicates with each other. The accommodation space 8a of the present embodiment is composed of an internal space in which two

balloon portions

8b and 8c communicate with each other.

The expansion portion 8 can be expanded toward the downward direction A1 of the thickness direction A by supplying the fluid to the accommodation space 8a. The expansion unit 8 of the present embodiment expands downward A1 by changing its form from the contracted form (see FIG. 5) described above to the expanded form (see FIG. 6), and becomes a posture capable of pressing the surface of the living body. .. More specifically, when the fluid is supplied to the accommodation space 8a, the expansion portion 8 receives a reaction force from the lower surface of the holding body 5 and expands in the downward direction A1. The fluid supplied to the accommodation space 8a of the expansion unit 8 is not limited to a gas, but may be a liquid.

As shown in FIG. 5, the contracted expansion portion 8 is arranged along the lower surface of the holding body 5 in a state where the accommodation space 8a is contracted. The accommodation space 8a of the expansion portion 8 communicates with a tube 28 extending to the outside of the holding body 5. A fluid such as air is supplied to the accommodation space 8a of the expansion portion 8 through the tube 28 from a fluid supply device connected to an inflation port as a connection portion 29 provided at the end of the tube 28. As a result, the expanded state of the expanded portion 8 can be changed, and the expanded portion 8 can be changed from the contracted form (see FIG. 5) to the expanded form (see FIG. 6).

The expansion portion 8 of the present embodiment includes a portion having translucency in the thickness direction A. More specifically, the expansion portion 8 of the present embodiment is composed of only a portion having translucency in the thickness direction A. As described above, it is preferable that the expansion portion 8 includes at least a portion having translucency in the thickness direction A. By doing so, it is possible to see through the expansion portion 8 from the upper side of the expansion portion 8 to the lower side of the expansion portion 8. Therefore, the position of the wound or the like on the surface of the living body can be visually recognized through the expansion portion 8.

The extension section 9 is extended from the extension section 8. The extension portion 9 has flexibility. The extension portion 9 is wound around the holding body 5. As a result, the extending portion 9 extends from the expanding portion 8 to the upper surface side of the holding body 5 on the opposite side of the expanding portion 8 with the holding body 5 interposed therebetween. The extension portion 9 is locked to the holding body 5 on the upper surface side of the holding body 5.

Specifically, the holding body 5 of the present embodiment defines a through hole 5a penetrating in the thickness direction A. The extension portion 9 of the present embodiment is wound around the holding body 5 through the through hole 5a. More specifically, the extending portion 9 of the present embodiment extends from the lower side on which the expanding portion 8 is located with the holding body 5 sandwiched between them toward the upper side, which is the opposite side thereof. Then, the extension portion 9 of the present embodiment is wound around the holding body 5 so as to be along the inner surface of the holding body 5 for partitioning the through hole 5a and the upper surface of the holding body 5. Further, the extending portion 9 is formed with a locking hole 9b on the upper surface side of the holding body 5 into which a locking projection 5b protruding from the upper surface of the holding body 5 is fitted. By fitting the locking projection 5b into the locking hole 9b, the extension portion 9 is positioned on the holding body 5. Further, the extension portion 9 is wound around the extension portion 8 from the lower surface side to the upper surface side of the holding body 5 at a position on the receiving portion 6 side. That is, the through hole 5a of the present embodiment is located on the receiving portion 6 side with respect to the expanding portion 8. Therefore, in the cross-sectional view shown in FIG. 5, the expansion portion 8 and the extension portion 9 constituting the pressing body 4 of the present embodiment are curved in a substantially U shape by being wound around the holding body 5. As a result, the expansion portion 8 can be expanded while rotating the portion of the extension portion 9 connected to the expansion portion 8 as the hinge portion 9a.

The expansion portion 8 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 by the hinge portion 9a of the extension portion 9. As described above, the pressing body 4 of the present embodiment is wound around the holding body 5 in a state where the sheet-shaped extending portion 9 is wound around the upper and lower surfaces of the holding body 5 through the through hole 5a of the holding body 5. It is fixed. Therefore, at the time of expansion, the expansion portion 8 rotates around the rotation center with the hinge portion 9a, which is a portion of the extension portion 9 connected to the expansion portion 8 below the through hole 5a, as the rotation center. Expand while moving. More specifically, the two balloon portions constituting the expansion portion 8 of the present embodiment are arranged so as to be overlapped in the thickness direction A. Further, one end of each of these two balloon portions is attached to the extension portion 9. That is, one end side of the two balloon portions is restrained by the extending portion 9. Therefore, even if the two balloon portions are expanded, the distance between the two balloon portions is not separated on the one end side. On the other hand, the other ends of the two balloon portions are not restrained at all. Therefore, when the two balloon portions are expanded, the distance between the two balloon portions is separated on the other end side. That is, in the two balloon portions constituting the expansion portion 8 of the present embodiment, the one end side attached to the extension portion 9 is the center of rotation, and the other end side not attached to the extension portion 9 is this time. It rotates around the center of motion. In this way, the expansion portion 8 of the present embodiment expands in the direction of inclination with respect to the thickness direction A. By forming the expansion portion 8 that expands in the direction of inclination with respect to the thickness direction A, the perforation P (see FIG. 11B) described later is likely to be narrowed or occluded. The details will be described later (see FIG. 12). However, the configuration for expanding in the direction of inclination with respect to the thickness direction A is not limited to the configuration of the pressing body 4 of the present embodiment.

The extension portion 9 of the present embodiment includes a portion having translucency in the thickness direction A at a position covering the upper surface of the holding body 5. Specifically, all the portions covering the upper surface of the holding body 5 of the extending portion 9 of the present embodiment are composed of portions having translucency in the thickness direction A. More specifically, the extension portion 9 of the present embodiment has a sheet shape, and the extension portion 9 has translucency in the thickness direction at an arbitrary position. However, the extending portion 9 may be configured to include, for example, a portion having translucency in the thickness direction only in a part of the position covering the upper surface of the holding body 5.

Examples of the constituent materials of the expansion portion 8 and the extension portion 9 of the pressing body 4 include soft polyvinyl chloride, polyurethane, polyethylene, polypropylene, polyester, ethylene-vinyl acetate copolymer (EVA), silicone, or any of these.

Further, the main body portion 31 includes the above-mentioned locking projection 5b that fits into the locking hole 9b of the extending portion 9 of the pressing body 4. The expansion portion 8 of the pressing body 4 described above is arranged on the lower surface side of the central portion of the main body portion 31.

Further, the main body 31 is fixed to the mounting surface 12 of the sticking sheet 2. Specifically, only the outer edge portion of the lower surface of the main body portion 31 is fixed to the mounting surface 12 of the sticking sheet 2 having a substantially C shape in a plan view. The central portion of the lower surface of the main body portion 31 is not covered with the sticking sheet 2. Therefore, the central portion of the lower surface of the main body portion 31 is not fixed to the mounting surface 12 of the sticking sheet 2.

Further, the line segment marker 7a of the present embodiment is provided at a position overlapping with the expansion portion 8 of the pressing body 4 in a plan view. Therefore, the compression device 1 is attached on the surface of the living body in a state where the line segment marker 7a is aligned so as to overlap a predetermined compression position on the surface of the living body in a plan view. As a result, a predetermined compression position on the surface of the living body can be appropriately compressed by the expansion unit 8. That is, by providing the line segment marker 7a, the compression device 1 can be easily positioned at an appropriate position on the surface of the living body.

The color of the region marker 7b is not particularly limited, but a greenish color is preferable. By making it green, medical professionals and the like can easily visually recognize the region marker 7b on blood or the surface of a living body. Therefore, it becomes easier to align the expansion portion 8 with the compression position on the surface of the living body by using the region marker 7b. When the area marker 7b is used as the frame line marker 7b1, it may be composed of a convex portion protruding from the upper surface of the holding body 5 or a concave portion such as a groove formed on the upper surface of the holding body 5.

Hereinafter, this portion is referred to as a "laminated portion". The laminated portion of the present embodiment is preferably configured by laminating portions having translucency. By doing so, in the compression device 1 of the present embodiment, the extending portion 9 of the pressing body 4, the line segment marker 7a of the holding body 5, the area marker 7b and their surroundings, and the expanding portion of the pressing body 4 are used. The other side can be visually recognized from one side of the thickness direction A through 8. As a result, according to the compression device 1 of the present embodiment, the alignment of the line segment marker 7a and the region marker 7b on the surface of the living body becomes easier. In this way, when all of the laminated portions are composed of translucent portions, the line segment marker 7a and the region marker 7b are in a mode in which they can be distinguished from all other layers of the laminated portion in a plan view.

The line segment marker 7a of the present embodiment and the frame line marker 7b as the area marker 7b are provided on the upper surface of the main body 31 of the holding body 5. Therefore, the line segment marker 7a and the area marker 7b of the present embodiment are easily visible to the medical staff who is operating the compression device 1. However, the line segment marker 7a and the area marker 7b may be provided inside the holding body 5. Further, the line segment marker 7a and the area marker 7b may be provided on the lower surface of the main body 31 of the holding body 5. Details of the configuration in which the line segment marker 7a and the region marker 7b are provided on the lower surface of the holding body 5 will be described later (see FIG. 9).

The method of providing the line segment marker 7a and the area marker 7b is not particularly limited, but for example, printing, fusion, adhesion, integral molding, or the like can be used.

Further, the line segment marker 7a of the present embodiment is provided at a position between the pair of gripping plate portions 32 in a plan view.

<Compression method using compression device 1>
Next, a method of compressing the surface of a living body performed by using the compression device 1 including an example of the method of attaching the compression device 1 according to the present disclosure will be described. FIG. 7 is a flowchart showing an example of a method of compressing the surface of a living body. The compression method shown in FIG. 7 includes a sticking step S1, a first compression step S2, a removal step S3, and a second compression step S4. 8A and 8B are diagrams showing an outline of the sticking step S1. FIG. 8C is a diagram showing an outline of the first compression step S2. FIG. 8D is a diagram showing an outline of the extraction step S3. FIG. 8E is a diagram showing an outline of the second compression step S4.

The compression method illustrated in FIGS. 7 and 8A to 8E is a compression method in which the perforation leading from the biological surface to the vein is narrowed or occluded by compressing the biological surface BS without occluding the vein. The perforation is formed by removing the sheath as the medical insertion member 100 in a state of being inserted into a vein such as a femoral vein through connective tissue from the biological surface BS. By the compression method shown here, hemostasis can be performed after the sheath as the medical insertion member 100 is removed. First, the perforation formed after removing the medical insertion member 100 will be described with reference to FIGS. 11A and 11B. FIG. 11A shows a state in which the sheath as the medical insertion member 100 is inserted into the femoral vein FV from the biological surface BS through the connective tissue CT. In FIG. 11A, three sheaths as the medical insertion member 100 are shown, but the number may be two or less, or four or more. FIG. 11B shows a state after removing the sheath as the medical insertion member 100 from the state shown in FIG. 11A. As shown in FIG. 11B, by removing the sheath as the medical insertion member 100, a perforation P is formed between the biological surface BS and the femoral vein FV. In the compression method shown in FIGS. 7 and 8A to 8E, the perforation P can be narrowed or occluded without occluding the femoral vein FV. Therefore, even when bleeding from a vein located deep from the surface of the living body is stopped, it is not necessary to narrow or occlude the vein itself, and bleeding can be stopped more efficiently. Hereinafter, the details of each of the steps S1 to S4 will be described with reference to FIGS. 8A to 8E.

FIG. 8A shows a state in which a sheath as a medical insertion member 100 is inserted into the femoral vein FV (see FIGS. 11A and 11B) from the biological surface BS. FIG. 8B shows a state in which the compression device 1 is completely attached to a predetermined position on the biological surface BS with the sheath as the medical insertion member 100 inserted in the living body. Further, in FIG. 8B, the details of the alignment of the line segment marker 7a and the insertion portion 100a of the medical insertion member 100 in a plan view are shown enlarged in the frame of the alternate long and short dash line. 8A and 8B show the usage state of the compression device 1 after the release sheet is peeled from the sticking surface 11.

As shown in FIGS. 8A and 8B, the compression device 1 is attached to the surface of the living body by sticking the sticking surface 11 of the sticking sheet 2 to the surface of the living body. Specifically, as shown in FIG. 8B, a portion of the sheath as the medical insertion member 100 inserted into the living body from the living body surface BS exposed to the outside from the living body surface BS is received by the receiving portion 6. Then, the sticking sheet 2 is stuck to the biological surface BS. Further, as shown in FIG. 8B, a part of the insertion portion 100a of the sheath as the medical insertion member 100 located on the same surface as the biological surface BS is aligned with the line segment marker 7a (FIG. 8B-2). See inside the dotted line frame). In the state of being aligned in this way, the sticking sheet 2 is stuck to the biological surface BS.

More specifically, as shown in FIG. 8B, in the present embodiment, the entire insertion portion 100a of the sheath as the medical insertion member 100 located on the same surface as the biological surface BS is located within the region marker 7b. It will be matched. In the state of being aligned in this way, the sticking sheet 2 is stuck to the biological surface BS. By providing such a region marker 7b, as shown in an enlarged example in the frame of the alternate long and short dash line on the left side of FIG. 8B, a plurality of markers (three in the frame of the alternate long and short dash line on the left side of FIG. 8B) are provided. Even when the medical insertion member 100 is inserted, all the insertion portions 100a can be aligned so as to fit within the region of the region marker 7b. Thereby, the compression device 1 can be easily attached to an appropriate position on the biological surface BS capable of compressing all the insertion portions 100a of the plurality of medical insertion members 100 with a predetermined compression force. Further, as shown in FIG. 8B, in the present embodiment, a thin sheath having an outer diameter of less than a predetermined value is not aligned with the line segment marker 7a within the region marker 7b (two points on the left side of FIG. 8B). (Refer to the inside of the chain line frame), for a thick sheath having an outer diameter of a predetermined value or more, a part of the outer surface of the insertion portion 100a is aligned with the line segment marker 7a within the region marker 7b (on the left and right sides of FIG. 8B). See inside the frame of the alternate long and short dash line). As described above, the line segment marker 7a of the present embodiment indicates a position in the region of the region marker 7b where a particularly high compression force can be obtained. Therefore, for example, even with a large-diameter sheath or the like that requires a high compression force, a predetermined compression force can be secured. Further, for example, even when both a large-diameter sheath that requires a high compression force and a small-diameter sheath that is thinner than this are included (see the frame of the alternate long and short dash line on the left side of FIG. 8B). By aligning the large-diameter sheath with the line segment marker 7a in the region marker 7b and not aligning the small-diameter sheath with the line segment marker 7a in the region marker 7b, the compression force in the region marker 7b is increased. Based on the difference, the desired compression force required for each sheath can be realized. After various alignments are performed in this way, the sticking sheet 2 is stuck to the biological surface BS. By providing both the line segment marker 7a and the region marker 7b, the compression device 1 can be attached to a more appropriate position on the biological surface BS according to the outer diameter and number of the medical insertion member 100 and the required compression force. Can be done.

As described above, the line segment marker 7a extends in an arc shape in the plan view seen in the thickness direction A. Therefore, in the present embodiment, a part of the outer surface of the insertion portion 100a of the medical insertion member 100 is aligned so as to be in contact with or overlap the line segment marker 7a in a plan view. The compression device 1 is mounted on the biological surface BS in such an aligned state.

Next, as shown in FIG. 8C, the syringe 30 as a fluid supply device is connected to the connection portion 29 of the tube 28. Through the tube 28, air is supplied to the accommodation space 8a (see FIG. 6) of the expansion portion 8 of the pressing body 4 of the compression device 1 to expand the expansion portion 8. By doing so, the vicinity of the wound on the biological surface BS can be pressed in advance before the sheath as the medical insertion member 100 is removed from the biological surface BS. In other words, compression of the biological surface BS is started with the sheath as the medical insertion member 100 inserted into the femoral vein FV as a vein from the biological surface BS through the connective tissue CT (see FIGS. 11A and 11B). do. In this way, the medical insertion member 100 is pressed before being removed from the biological surface BS. As a result, the biological surface BS can be pressed immediately after the sheath as the medical insertion member 100 is removed. Therefore, the perforation P (see FIG. 11B) extending from the biological surface BS to the femoral vein FV (see FIGS. 11A and 11B) can be narrowed or occluded immediately after the sheath is removed.

Next, as shown in FIG. 8D, the sheath as the medical insertion member 100 is removed from the biological surface BS. Removal of this sheath forms the perforation P shown in FIG. 11B. If the biological surface BS is not compressed at all in this state, bleeding occurs from the femoral vein FV through the perforation P and the wound on the biological surface BS. However, in the compression method shown here, as shown in FIG. 8C, the biological surface BS is compressed in advance before the sheath as the medical insertion member 100 is removed from the biological surface BS. Therefore, immediately after the sheath is removed, the biological surface BS can be pressed so as to narrow or occlude the perforation P (see FIG. 11B), and the amount of bleeding immediately after the sheath is removed can be suppressed.

Next, as shown in FIG. 8E, the syringe 30 as a fluid supply device is reconnected to the connection portion 29 of the tube 28. Air is supplied again to pressurize the accommodating space 8a of the expansion portion 8 of the compression device 1 through the tube 28, or the air is evacuated to reduce the pressure. In other words, the compression force of the biological surface BS is adjusted after the sheath as the medical insertion member 100 is removed. As a result, the compression force of the biological surface BS is adjusted to further narrow or occlude the perforation P (see FIG. 11B) without occluding the femoral vein FV (see FIGS. 11A and 11B), thereby reducing the amount of bleeding. It can be greatly reduced or bleeding can be stopped.

More specifically, if bleeding is confirmed after removing the sheath, the compression force is slowly increased and pressurized until hemostasis is achieved. On the other hand, if hemostasis is confirmed after the sheath is removed, the compression force is slowly reduced to reduce the pressure until bleeding is confirmed. Then, after bleeding is confirmed, the compression force is slowly increased and pressurized until hemostasis is achieved. By doing so, it is possible to prevent obstruction of the femoral vein FV (see FIGS. 11A and 11B) due to overpressurization.

Further, whether or not the biological surface BS is appropriately compressed may be detected by using an ultrasonic device. Specifically, the pressing body 4 and the holding body 5 are formed of a material having ultrasonic wave transmission, and a fluid having ultrasonic wave transmission such as water is supplied to the expansion portion 8 of the pressing body 4. , The compression state by the compression device 1 can be diagnosed by ultrasonic waves. That is, the ultrasonic device can detect whether or not the femoral vein FV (see FIGS. 11A and 11B) is occluded. The compression force of the compression device 1 may be adjusted based on the diagnosis result by the ultrasonic device.

Hemostasis can be completed by maintaining the compressed state for several hours (for example, 2 to 6 hours). After the hemostasis is completed, the compression device 1 is removed from the biological surface BS by peeling the adhesive surface 11 of the adhesive sheet 2 from the biological surface BS.

The compression method shown here narrows or occludes the perforation P (see FIG. 11B) without occluding the femoral vein FV (see FIGS. 11A, 11B). In the case of venous hemostasis, bleeding can be stopped by stenosis or occlusion of perforation P (see FIG. 11B). On the other hand, in the case of hemostasis of the femoral artery, for example, even if only the perforation is occluded, blood leaks and spreads into the connective tissue CT (see FIGS. 11A and 11B), so that hemostasis cannot be performed. In the case of hemostasis of the femoral artery, a large-scale measure such as a method of compressing the artery itself so strongly as to narrow or occlude it or a method of closing a hole in the arterial wall is required.

Therefore, in the above-mentioned compression method, it is preferable to compress the biological surface BS to a position where the compression depth from the biological surface BS is 5 mm to 20 mm. By setting the compression depth within the above range, it is easy to realize a compression state in which the perforation P (see FIG. 11B) is narrowed or occluded without occluding the vein. The compression depth is more preferably 5 mm to 15 mm, and even more preferably 8 mm to 12 mm.

Further, in the above compression method, the biological surface BS, it is preferable to press the living body surface BS at ^{10g / cm 2 ~ 600g / cm} 2. This compression pressure is the pressure after the sheath as the medical insertion member 100 is removed, and does not mean the compression force before the sheath is removed as described above. By setting the compression pressure in the above range, it is easy to realize a compression state in which the perforation P (see FIG. 11B) is narrowed or occluded without occluding the vein. The compression pressure is ^{more preferably 50 g / cm 2} to 400 g / cm ^2, and even more preferably 100 g / cm ² to 300 g / cm ² .

Further, it is preferable to press the biological surface BS along a direction orthogonal to the extending direction of the perforation P (see FIG. 11B). "Compressing along a direction orthogonal to the extending direction of the perforation" is not limited to compressing only in the direction orthogonal to the extending direction of the perforation, but is orthogonal to the extending direction of the perforation. It also means that the pressure is applied in a direction of inclination at an angle of a predetermined angle or less (for example, 30 degrees or less) with respect to the direction of the squeeze. The compression device 1 of the present embodiment can compress the biological surface BS along a direction orthogonal to the extending direction of the perforation P (see FIG. 11B).

Specifically, as described above, the expansion portion 8 of the pressing body 4 of the present embodiment can be expanded in a direction in which it is inclined with respect to the thickness direction A. By doing so, the surface of the living body can be compressed along the direction orthogonal to the extending direction of the perforation P (see FIG. 11B). Specifically, as shown in FIGS. 11A and 11B, the sheath as the medical insertion member 100 is not in a direction orthogonal to the biological surface BS (the same direction as the thickness direction A), but with respect to the biological surface BS. It is inserted in a direction inclined to one side with respect to the orthogonal direction. Therefore, as shown in FIG. 11B, the extending direction of the perforation P is also inclined with respect to the direction orthogonal to the biological surface BS. Therefore, the direction in which the perforation P is inclined in the direction opposite to the extending direction of the perforation P with respect to the thickness direction A which is orthogonal to the biological surface BS (hereinafter, may be referred to as “inclination direction F”). If the expansion portion 8 is expandable, it becomes easy to press the biological surface BS along the direction orthogonal to the extending direction of the perforation P. This facilitates the realization of a compression device 1 that narrows or occludes the perforation P without occluding the veins such as the femoral vein FV of FIGS. 11A and 11B. FIG. 12 is a diagram showing a state in which the perforation P shown in FIG. 11B is narrowed or occluded by the compression device 1. As shown in FIG. 12, according to the compression device 1, the perforation P is more likely to be narrowed or occluded without further occluding the vein such as the femoral vein FV.

According to the compression method shown in FIGS. 7A to 8E, hemostasis can be performed by narrowing or occluding the perforation P (see FIG. 11B) without occluding a vein such as a femoral vein FV. .. In particular, by realizing the above-mentioned compression method with the compression device 1, it is possible to stop bleeding by a simple method without the need for pressure by a medical worker or the use of a large-scale hemostatic device.

<Compression on the surface of the living body by the compression device 1>
As shown in FIG. 12, in the compression device 1, the expansion portion 8 of the pressing body 4 of the compression member 3 is in a vertical direction perpendicular to the living body surface BS in a state where the sticking sheet 2 is attached to the living body (FIG. 12). Then, it is the same direction as the thickness direction A, and it is possible to press the surface of the living body in the inclination direction F which is inclined with respect to the vertical direction in FIG. 12; hereinafter, simply referred to as “vertical direction”). By doing so, as shown in FIG. 12, the perforation P is easily narrowed or occluded without occluding the vein such as the femoral vein FV.

FIG. 13 is a front view of the state shown in FIG. 12 as viewed from the living body surface BS side. In other words, FIG. 13 shows a front view of the biological surface BS at a position where it is compressed by the compression device 1. Here, "front view of the surface of the living body at a position where it is compressed by the compression device" means that the portion of the surface of the living body to be compressed by the compression device is perpendicular to the portion before compression. It means the state seen from the direction. FIG. 13 shows a front view of the inguinal region. In the front view shown in FIG. 13, the direction in which the biological surface BS is compressed (see the white arrow “AR1” in FIG. 13) is the insertion direction of the sheath from the biological surface BS toward the vein in the extending direction G of the perforation P. It faces G1 (see the white arrow "AR2" in FIG. 13). That is, the direction in which the compression device 1 presses the biological surface BS is opposed to the sheath insertion direction G1 in the front view shown in FIG. By doing so, it becomes easy to narrow or occlude the perforation P (see FIGS. 11B and 12) without occluding the vein such as the femoral vein FV.

In other words, as shown in FIG. 12, the extending direction G of the perforation P is inclined with respect to the biological surface BS and is perpendicular to the biological surface BS (vertical direction in FIG. 12). But it's tilted. Further, as shown in FIG. 12, the compression direction of the biological surface BS by the compression device 1 is also an inclination with respect to the biological surface BS and a vertical direction perpendicular to the biological surface BS (vertical direction in FIG. 12). It is also inclined to. Further, as shown in FIG. 12, the extending direction G of the perforation P is opposite to the inclination direction F as the compression direction of the living body surface by the compression device 1 with respect to the vertical direction (vertical direction in FIG. 12). Leaning on. That is, the compression of the living body surface by the compression device 1 is executed so that the compression direction intersects with the extension direction G of the perforation P. As a result, the perforation P can be efficiently narrowed or occluded.

[Second Embodiment]
Next, the compression device 301 as the second embodiment will be described. Here, the differences from the compression device 1 (see FIG. 1 and the like) described above will be mainly described, and the description of common configurations will be omitted.

FIG. 9 is a bottom view of the compression device 301 of the present embodiment in a state where the pressing body 4 (see FIG. 1 and the like) is removed. The compression device 301 of the present embodiment is different from the compression device 1 described above in the positions provided on the holding bodies of the line segment marker and the region marker.

The line segment marker 307a and the area marker 307b of the present embodiment are provided on the lower surface of the holding body 305. FIG. 10 illustrates a state in which a part of the outer surface of the insertion portion 100a located on the same surface as the living body surface of the medical insertion member 100 is positioned with respect to the line segment marker 307a provided on the lower surface of the holding body 305. It is a schematic diagram for this. In other words, FIG. 10 is a schematic diagram for explaining the effect of the line segment marker 307a provided on the lower surface of the holding body 305. In FIG. 10, for convenience of explanation, the line segment marker 1007a provided on the upper surface of the holding body 305 is shown for comparison. As shown in FIG. 10, by providing the line segment marker 307a on the lower surface of the holding body 305, the thickness of the holding body 305 in the thickness direction A is increased as compared with the configuration in which the line segment marker 1007a is provided on the upper surface of the holding body 305. It is possible to suppress the occurrence of misalignment due to it. That is, when the line segment marker 1007a is provided on the upper surface of the holding body 305, the line segment marker 1007a is separated from the biological surface on the lower surface side of the holding body 305 by at least the thickness of the holding body 305. Therefore, when the line segment marker 1007a is positioned at a predetermined position on the surface of the living body from an erroneous viewpoint deviated from the plan view (for example, the viewpoint PV shown in FIG. 10), the line segment marker 1007a is aligned in the in-plane direction H of the living body surface. And a predetermined position on the surface of the living body (a part of the outer surface of the insertion portion 100a in FIG. 10) may be misaligned. On the other hand, in the present embodiment, since the line segment marker 307a is provided on the lower surface of the holding body 305, the above-mentioned positional deviation due to the difference in viewpoint is less likely to occur. That is, by providing the line segment marker 307a on the lower surface of the holding body 305, the compression device 301 can be more easily attached to an appropriate position on the surface of the living body. In FIG. 10, for convenience of explanation, the effect of providing only the line segment marker 307a on the lower surface of the holding body 305 has been described, but the same applies to the area marker 307b, and the description thereof will be omitted here.

The line segment marker 307a of the present embodiment is composed of a groove portion extending in an arc shape formed on the lower surface of the holding body 305. Further, the area marker 307b of the present embodiment is composed of a frame line marker 307b1 for partitioning a predetermined area by a rectangular groove formed on the lower surface of the holding body 305.

The area marker 307b of the present embodiment is partially cut off by the through hole 305a of the holding body 305 in a plan view, but is not limited to this configuration. The region marker 307b may be provided on only one side of the through hole 305a of the holding body 305 in a plan view.

The border marker 307b1 as the region marker 307b of the present embodiment has a rectangular shape in a plan view, but this shape is not particularly limited. The border marker 307b1 as the region marker 307b may have a polygonal shape other than a circular shape, an oval shape, and a square shape in a plan view.

The compression device according to the present disclosure and the method of attaching the compression device are not limited to the specific configurations and methods shown in the first and second embodiments described above, and are not limited to the description of the scope of claims. , Various modifications and changes are possible. Further, the compression device constructed by combining the configurations of each part of the compression device shown in the first embodiment and the second embodiment also belongs to the technical scope of the present disclosure.
