According to this disclosure, the compression device that is capable of being easily positioned at an appropriate position on the biological surface and the method for adhering the compression device can be provided.
Set forth below with reference to the accompanying drawings is a detailed description of embodiments of a compression device, adhering method and compression method representing examples of the new compression device and methods disclosed here. In the drawings, common members and portions are denoted by the same reference numerals.
The compression device 1 includes an adhesive sheet 2 and a compression member 3.
The adhesive sheet 2 has an adhesion surface 11, which can be adhered to a biological surface, on one side in a thickness direction A. The compression member 3 according to the present embodiment is attached to an attachment surface 12 on a side opposite to the adhesion surface 11 of the adhesive sheet 2.
Hereinafter, a surface of the adhesive sheet 2 on which the adhesion surface 11 is provided is referred to as a “lower surface of the adhesive sheet 2”. In addition, a surface of the adhesive sheet 2 on which the attachment surface 12 is provided is referred to as an “upper surface of the adhesive sheet 2”. Hereinafter, for convenience of description, the one side in the thickness direction A, which is a direction from the attachment surface 12 to the adhesion surface 11 in the thickness direction A, may be simply referred to as a “downward direction A1” or a “lower side”. In addition, for convenience of description, the other side in the thickness direction A, which is a direction from the adhesion surface 11 to the attachment surface 12 in the thickness direction A, may be simply referred to as an “upward direction A2” or an “upper side”. Further, in a plan view (see
The compression member 3 is attached to the adhesive sheet 2. Specifically, the compression member 3 is fixed to the adhesive sheet 2 on a side opposite to the adhesion surface 11. More specifically, the compression member 3 according to the present embodiment is fixed to the attachment surface 12 of the adhesive sheet 2. The compression member 3 can compress the biological surface in a state in which the adhesion surface 11 is adhered to the biological surface. Accordingly, the compression device 1 is fixed to a position on the biological surface by adhering the adhesion surface 11 to the biological surface. According to the compression device 1, a predetermined site on the biological surface can be compressed by the compression member 3 in a state in which the adhesion surface 11 of the adhesive sheet 2 is adhered to the biological surface. The predetermined site on the biological surface includes, for example, a wound on the biological surface or its vicinity formed by inserting a medical insertion member such as a puncture needle, a catheter, and a sheath into a blood vessel of a living body. After the medical insertion member is removed from the living body, bleeding can be stopped by compressing the wound on the biological surface or its vicinity with the compression member 3 for predetermined time.
More specifically, the compression member 3 includes the pressing body 4 and a holding body 5. The pressing body 4 can press the biological surface by extending in the thickness direction A of the adhesive sheet 2. The holding body 5 is fixed to the adhesive sheet 2 on the side opposite to the adhesion surface 11, and holds the pressing body 4 to be extendable in the thickness direction A.
In the plan view of the compression device 1 seen in the thickness direction A (see
The receiving portion 6 according to the present embodiment is a region in which the adhesive sheet 2 is not disposed outside the outer edge of the holding body 5 in the plan view of the compression device 1 seen in the thickness direction A (see
The compression device 1 may not include the receiving portion 6. However, by providing the receiving portion 6, the compression device 1 can be attached to the biological surface in a state in which a portion of the medical insertion member 100 (see
The pressing body 4 includes the inflatable portion 8 and an extending portion 9.
The inflatable portion 8 is disposed between the biological surface and the holding body 5 in a state in which the adhesion surface 11 of the adhesive sheet 2 is adhered to the biological surface (hereinafter, referred to as an “adhering state of the compression device 1”). The inflatable portion 8 can be inflated in the thickness direction A in the adhering state of the compression device 1. That is, the pressing body 4 according to the present embodiment extends in the thickness direction A by inflating the inflatable portion 8 in the thickness direction A. When the inflatable portion 8 is inflated in the adhering state of the compression device 1, the inflatable portion 8 presses the biological surface by receiving a reaction force from the holding body 5. Hereinafter, a form before the inflatable portion 8 is inflated will be referred to as a “deflated form” of the inflatable portion 8. In addition, a form in which the inflatable portion 8 is inflated from the deflated form is referred to as an “inflated form” of the inflatable portion 8. The compression device 1 according to the present embodiment, in the adhering state, does not compress the biological surface by the inflatable portion 8 when the inflatable portion 8 is in the deflated form. On the other hand, the compression device 1 according to the present embodiment, in the adhering state, compresses the biological surface by the inflatable portion 8 when the inflatable portion 8 is in the inflated form.
The extending portion 9 is extended or extends from the inflatable portion 8. In addition, the extending portion 9 has flexibility (i.e., the extending portion 9 is flexible). The extending portion 9 is wound around the holding body 5. Accordingly, the extending portion 9 extends from the inflatable portion 8 to an upper surface side of the holding body 5 on a side opposite to the inflatable portion 8 with the holding body 5 interposed therebetween. The extending portion 9 is locked to the holding body 5 on the upper surface side of the holding body 5.
The extending portion 9 according to the present embodiment includes a light-transmitting portion or section 9c having translucency in the thickness direction A at a position at which an upper surface of the holding body 5 is covered. Specifically, an entire portion of the extending portion 9 according to the present embodiment with which the upper surface of the holding body 5 is covered is the light-transmitting portion 9c. More specifically, the extending portion 9 according to the present embodiment has a sheet shape, and has translucency in a thickness direction at any position. Alternatively, the extending portion 9 may include the light-transmitting portion 9c having translucency in the thickness direction in, for example, only a part at the position at which the upper surface of the holding body 5 is covered.
The holding body 5 includes, at a position overlapping with the light-transmitting portion 9c of the extending portion 9 of the pressing body 4 in the plan view seen in the thickness direction A, a marker portion 42 that can be visually identified. More specifically, the holding body 5 according to the present embodiment includes, at a position overlapping with not only the light-transmitting portion 9c of the extending portion 9 of the pressing body 4 but also the inflatable portion 8 of the pressing body 4 in the plan view seen in the thickness direction A, the marker portion 42 that can be visually identified. As shown for example in
The details will be described later, and the marker portion 42 is used for alignment when the compression device 1 is attached to the biological surface. The marker portion 42 according to the present embodiment includes both a region marker 7a and a position marker 7b. The region marker 7a according to the present embodiment indicates a region in which the inflatable portion 8 can compress the biological tissue with a compression force of a first predetermined value or more in a state in which the compression device 1 is attached to the biological surface. The position marker 7b according to the present embodiment indicates a reference position for aligning the medical insertion member 100 (see
The marker portion 42 may be, for example, one convex portion protruding from the upper surface of the holding body 5. The marker portion 42 may be, for example, a concave portion such as a groove portion formed on the upper surface of the holding body 5. In addition, the marker portion 42 may be, for example, one convex portion protruding from a lower surface of a portion having translucency of the holding body 5. The marker portion 42 may be, for example, a concave portion such as a groove portion formed on the lower surface of the portion having translucency of the holding body 5. Further, for example, the marker portion 42 may have a transmittance different from that of the periphery. As an example, the marker portion 42 may be a portion having a transmittance lower than that of the periphery, which is located in the portion having translucency of the holding body 5. In addition, for example, the marker portion 42 may have a color different from that of the periphery. The marker portion 42 may be, for example, a paint or the like with which a part of the upper surface or the lower surface of the holding body 5 is coated. As described above, the configuration of the marker portion 42 is not particularly limited as long as the marker portion 42 can be identified separately from the periphery through the light-transmitting portion 9c of the extending portion 9 of the pressing body 4 in a plan view under a usage environment, particularly a top view (see
Since the holding body 5 includes, at the position overlapping with the light-transmitting portion 9c in the plan view, the marker portion 42 that can be visually identified, even when the pressing body 4 including the extending portion 9 wound around the holding body 5 is used, a health care worker who operates the compression device 1 can visually identify the marker portion 42 through the light-transmitting portion 9c of the extending portion 9. Therefore, even when the pressing body 4 including the extending portion 9 wound around the holding body 5 is used, the health care worker can align the compression device 1 at an appropriate position on the biological surface using the marker portion 42.
Hereinafter, details of each member and each portion of the compression device 1 according to the present embodiment will be described.
As described above, the adhesive sheet 2 includes the adhesion surface 11 on the one side in the thickness direction A. In addition, as described above, the adhesive sheet 2 includes the attachment surface 12 on the other side in the thickness direction A, that is, on the side opposite to the adhesion surface 11. The adhesive sheet 2 has flexibility. Therefore, the adhesive sheet 2 can be deformed according to a shape of the biological surface. In addition, the adhesion surface 11 easily follows deformation of the biological surface. As a result, it is possible to prevent the compression device 1 from being unintentionally released from the biological surface.
The adhesive sheet 2 includes a plurality of layers including, for example, a base material layer and an adhesive layer.
The base material layer is formed of, for example, a thin resin sheet. More specifically, the base material layer is formed of, for example, a white spunlace nonwoven fabric of polyester fibers, and has a thickness in a range of 5 μm to 150 μm, and for example, 30 μm. However, a 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, and the like may be used.
The adhesive layer is formed of, for example, an adhesive such as a rubber-based adhesive, an acrylic-based adhesive, and a silicon-based adhesive. The adhesive layer is stacked on the base material layer directly or indirectly with another layer interposed therebetween. The adhesion surface 11 of the adhesive sheet 2 according to the present embodiment is an adhesive layer.
The adhesive sheet 2 may further include another layer in addition to the base material layer and the adhesive layer. The adhesive sheet 2 may include, for example, a surface layer. The surface layer is formed of, for example, a resin having a thickness of about 5 μm to 50 μm. More specifically, examples of a material of the surface layer include polyester, polyamide, polyamideimide, polyethylene, polypropylene, polycarbonate, polyurethane, polyvinyl chloride, and fluororesin. The surface layer is stacked on the base material layer directly or indirectly with another layer interposed therebetween on a side opposite to the adhesive layer with the base material layer interposed therebetween. Therefore, the attachment surface 12 of the adhesive sheet 2 may be a surface layer.
More specifically, the adhesive sheet 2 may be formed of a nonwoven fabric tape having an adhesive agent as an adhesive on one surface thereof. Further, the adhesive sheet 2 may be formed of a double-sided tape in which adhesive layers are provided on both sides of the base material layer. When the adhesive sheet 2 is formed of the double-sided tape, the compression member 3 can be fixed to the adhesive sheet 2 by adhering the holding body 5 of the compression member 3 to one adhesive layer of the adhesive sheet.
The adhesive sheet 2 according to the present embodiment has a substantially C-shaped outer shape in the plan view seen in the thickness direction A. As shown in
The adhesion surface 11 of the adhesive sheet 2 is covered with a release sheet in an unused state before being adhered to the biological surface. The release sheet is removed by being released from the adhesion surface 11 by a user when the adhesive sheet 2 is adhered to the biological surface. When the release sheet is removed from the adhesion surface 11 and the adhesion surface 11 is exposed, the adhesion surface 11 of the adhesive sheet 2 is brought into a state of being capable of being adhered to the biological surface (hereinafter, referred to as a “use state” for convenience of description). The release sheet may be formed of, for example, a release paper or a sheet material made of resin. The compression device 1 shown in
As described above, the pressing body 4 of the compression member 3 according to the present embodiment includes the inflatable portion 8 and the extending portion 9. The inflatable portion 8 according to the present embodiment can be inflated by being supplied with a fluid. Specifically, the inflatable portion 8 according to the present embodiment defines accommodation spaces 8a in which a fluid such as gas can be accommodated. The inflatable portion 8 according to the present embodiment includes two balloon portions 8b and 8c that are connected to each other such that the inside of the balloon portion 8b communicates with the inside of the balloon portion 8c. The accommodation spaces 8a according to the present embodiment are internal spaces in which the two balloon portions 8b and 8c communicate with each other. The inflatable portion 8 according to the present embodiment can be inflated by supplying the fluid to the accommodation spaces 8a. The inflatable portion 8 according to the present embodiment includes a plurality of balloon portions, and a configuration of the inflatable portion 8 is not limited to the configuration of the present embodiment. The inflatable portion 8 may include, for example, only one balloon portion.
More specifically, the inflatable portion 8 according to the present embodiment can be inflated toward the downward direction A1 in the thickness direction A by supplying the fluid to the accommodation spaces 8a. The inflatable portion 8 according to the present embodiment is inflated toward the downward direction A1 by changing from the deflated form (see
As shown in
The inflatable portion 8 according to the present embodiment includes a portion having translucency in the thickness direction A.
“A portion having translucency in the thickness direction A” means a semi-transparent or transparent portion in the thickness direction A. More specifically, the inflatable portion 8 according to the present embodiment includes only the portion having translucency in the thickness direction A. Accordingly, it is preferable that the inflatable portion 8 includes at least the portion having translucency in the thickness direction A. Accordingly, a lower side of the inflatable portion 8 can be seen from an upper side of the inflatable portion 8 through the inflatable portion 8. Therefore, a position of the wound or the like on the biological surface can be visually identified through the inflatable portion 8.
Constituent materials of the inflatable portion 8 of the pressing body 4 include, for example, soft polyvinyl chloride, polyurethane, polyethylene, polypropylene, polyester, ethylene-vinyl acetate copolymer (EVA), silicone, or a material having flexibility obtained by mixing any of these materials.
As described above, the extending portion 9 is extended from the inflatable portion 8 and is wound around the holding body 5. Specifically, the holding body 5 according to the present embodiment defines a through hole 5a penetrating in the thickness direction A. The extending portion 9 according to the present embodiment is wound around the holding body 5 through the through hole 5a. More specifically, the extending portion 9 according to the present embodiment extends from a lower side at which the inflatable portion 8 is located with the holding body 5 interposed therebetween toward an upper side opposite to the lower side. The extending portion 9 according to the present embodiment is wound around the holding body 5 along an inner surface of the holding body 5 that defines the through hole 5a and the upper surface of the holding body 5. In addition, the extending portion 9 is formed with a locking hole 9b on the upper surface side of the holding body 5. A locking protrusion 5b protruding from the upper surface of the holding body 5 is fitted into the locking hole 9b. The extending portion 9 is positioned on the holding body 5 by fitting the locking protrusion 5b into the locking hole 9b. In addition, the extending portion 9 is wound around the holding body 5 from a lower surface side to the upper surface side of the holding body 5 on a receiving portion 6 side with respect to the inflatable portion 8. That is, the through hole 5a according to the present embodiment is located on the receiving portion 6 side with respect to the inflatable portion 8, and the part of the extending portion 9 that extends through the through hole 5a is located closer to the receiving portion 6 than the inflatable portion 8. Therefore, in a cross-sectional view shown in
As shown in
Constituent materials from which the extending portion 9 of the pressing body 4 may be fabricated include, for example, soft polyvinyl chloride, polyurethane, polyethylene, polypropylene, polyester, ethylene-vinyl acetate copolymer (EVA), silicone, or a material having flexibility obtained by mixing any of these materials.
The holding body 5 includes a main body portion 31 that is flat and has a substantially quadrangular shape in the plan view, and a pair of gripping plate portions 32 that protrude from the main body portion 31 in the upward direction A2 and that face each other.
The main body portion 31 is formed with the through hole 5a. In addition, the main body portion 31 includes the locking protrusion 5b fitted into the locking hole 9b of the extending portion 9 of the pressing body 4. The inflatable portion 8 of the pressing body 4 is disposed at a lower surface side of a central portion of the main body portion 31.
The main body portion 31 is fixed to the attachment surface 12 of the adhesive sheet 2. Specifically, only an outer edge portion of a lower surface of the main body portion 31 is fixed to the attachment surface 12 of the adhesive sheet 2 having a substantially C shape in the plan view. The central portion of the lower surface of the main body portion 31 is not covered with the adhesive sheet 2. Therefore, the central portion of the lower surface of the main body portion 31 is not fixed to the attachment surface 12 of the adhesive sheet 2.
The main body portion 31 of the holding body 5 is provided with the marker portion 42. By providing the marker portion 42, the inflatable portion 8 can appropriately compress a compression position on the biological surface to be pressed and compressed by the inflatable portion 8 of the pressing body 4. Specifically, the marker portion 42 according to the present embodiment indicates a place where the biological tissue can be compressed with a compression force of a predetermined value or more by the inflatable portion 8 in the top view (see
The marker portion 42 according to the present embodiment is provided on an upper surface of the main body portion 31 of the holding body 5. Therefore, it is easy for the health care worker who is operating the compression device 1 to visually identify the marker portion 42 according to the present embodiment. Alternatively, the marker portion 42 may be provided inside the holding body 5. Further, the marker portion 42 may be provided on the lower surface of the main body portion 31 of the holding body 5. The details of the configuration in which the marker portion 42 is provided on the lower surface of the holding body 5 will be described later (see
The marker portion 42 according to the present embodiment includes the region marker 7a and the position marker 7b. The region marker 7a is a marker that defines a predetermined region in the plan view seen in the thickness direction A. As described above, the region marker 7a according to the present embodiment defines the region in which the inflatable portion 8 can compress the biological tissue with the compression force of the first predetermined value or more in the state in which the compression device 1 is attached to the biological surface. In addition, the position marker 7b is a marker indicating a predetermined reference position in the predetermined region defined by the region marker 7a in the plan view seen in the thickness direction A. The position marker 7b according to the present embodiment indicates a reference position for aligning a part of an outer surface of an insertion portion 100a (see
The details will be described later, and as shown in an enlarged manner in a frame of a two-dot chain line on a left side in
The region marker 7a according to the present embodiment is a frame line marker 7a1 surrounding a predetermined region. The frame line marker 7a1 as the region marker 7a can be implemented, for example, by a part of the upper surface of the main body portion 31 of the holding body 5 formed of a resin kneaded with a dye, a colored paint, and the like. A color of the frame line marker 7a1 as the region marker 7a is not particularly limited, and is preferably a green-based color. By using the green-based color, the health care worker or the like can easily and visually identify the frame line marker 7a1 on blood or the biological surface. Therefore, it is easier to align the frame line marker 7a1 as the region marker 7a at the compression position on the biological surface. In addition, the frame line marker 7a1 as the region marker 7a may be constituted by a convex portion protruding from the upper surface of the holding body 5 or a concave portion such as a groove portion formed on the upper surface of the holding body 5.
The frame line marker 7a1 as the region marker 7a according to the present embodiment has a rectangular shape (e.g., defined by intersecting straight lines), but the shape is not particularly limited. The frame line marker 7a1 may have, for example, a circular shape, an oval shape, and a polygonal shape other than a square shape. In addition, a part of the frame line marker 7a1 as the region marker 7a according to the present embodiment is cut off by the through hole 5a of the holding body 5, but the configuration is not limited thereto. The frame line marker 7a1 may be provided only on a side opposite to the receiving portion 6 side with respect to the through hole 5a. As shown in
The region marker 7a is not limited to the frame line marker 7a1 that defines a predetermined region by a frame line. The region marker 7a may have a configuration in which a predetermined region is bordered by an outer edge of a region filled with a predetermined color. However, by setting the region marker 7a as the frame line marker 7a1, a contour of the predetermined region becomes clear, and thus the health care worker can more easily identify the predetermined region.
As described above, the position marker 7b is located in the predetermined region defined by the region marker 7a in the plan view. As described above, the position marker 7b according to the present embodiment indicates the reference position for aligning a part of the outer surface of the insertion portion 100a (see

The position marker 7b according to the present embodiment is a line segment marker 7b1 extending in the predetermined region defined by the region marker 7a in the plan view seen in the thickness direction A. By using the line segment marker 7b1, regardless of an outer diameter of the medical insertion member 100 (see
The line segment marker 7b1 as the position marker 7b can be implemented, for example, by a part of the upper surface of the main body portion 31 of the holding body 5 formed of a resin kneaded with a dye, a colored paint, and the like. A color of the line segment marker 7b1 as the position marker 7b is not particularly limited, and is preferably a green-based color. By using the green-based color, the health care worker or the like can easily and visually identify the line segment marker 7b1 on blood or the biological surface. The line segment marker 7b1 as the position marker 7b may be constituted by a convex portion protruding from the upper surface of the holding body 5 or a concave portion such as a groove portion formed on the upper surface of the holding body 5.
A shape of the line segment marker 7b1 as the position marker 7b in the plan view is not particularly limited. The line segment marker 7b1 as the position marker 7b according to the present embodiment extends in an arc shape in the plan view. With the line segment marker 7b1 having such a shape, it is easy to align the insertion portion 100a extending in an arc shape in a convex shape in the plan view such that a part of the outer surface of the insertion portion 100a enters a concave portion of the line segment marker 7b1. Therefore, the shape of the line segment marker 7b1 as the position marker 7b in the plan view is not particularly limited, may be an extending linear shape, and the line segment marker 7b1 preferably has a concave portion such as an arc shape or a V shape according to the present embodiment. As shown in

The marker portion 42 of the main body portion 31 of the holding body 5 may have a non-transparent configuration in the thickness direction A, and is preferably a semi-transparent or transparent portion having translucency in the thickness direction A. Specifically, the region marker 7a and the position marker 7b according to the present embodiment are preferably semi-transparent or transparent portions having translucency in the thickness direction A. Accordingly, the health care worker can visually identify a degree of overlap between the marker portion 42 and the position on the biological surface to be aligned with the marker portion 42.
It is preferable that the periphery of the marker portion 42 of the main body portion 31 of the holding body 5 has translucency in the thickness direction A. Specifically, it is preferable that the holding body 5 according to the present embodiment includes a portion having translucency in the thickness direction A in an adjacent periphery outside the region marker 7a in the plan view seen in the thickness direction A. Further, it is preferable that the holding body 5 according to the present embodiment has translucency in the thickness direction A in the predetermined region defined by the region marker 7a. Accordingly, when the health care worker performs an operation of moving the compression device 1 along the biological surface such that the marker portion 42 overlaps with a predetermined position on the biological surface, the health care worker can move the compression device 1 while visually identifying the position on the biological surface through the portion having translucency in the periphery of the marker portion 42. That is, since the periphery of the marker portion 42 of the main body portion 31 of the holding body 5 has translucency in the thickness direction A, an operation of attaching the compression device 1 to the appropriate position on the biological surface becomes easier.
As described above, the inflatable portion 8 and the extending portion 9 of the pressing body 4 according to the present embodiment also have translucency in the thickness direction A. In the compression device 1 according to the present embodiment, the extending portion 9 of the pressing body 4, the marker portion 42 of the holding body 5 and the periphery thereof, and the inflatable portion 8 of the pressing body 4 are stacked in the thickness direction A. Hereinafter, this part is referred to as a “stacked portion”. It is preferable that the stacked portion according to the present embodiment is formed by stacking the portions having translucency. Accordingly, in the compression device 1 according to the present embodiment, it is possible to visually identify one side from the other side in the thickness direction A through the extending portion 9 of the pressing body 4, the marker portion 42 of the holding body 5 and the periphery thereof, and the inflatable portion 8 of the pressing body 4. As a result, according to the compression device 1 according to the present embodiment, the alignment of the marker portion 42 on the biological surface becomes easier. As described above, when the entire stacked portion is constituted by portions having translucency, it is preferable that the marker portion 42 can be identified with respect to all the other layers of the stacked portion in the plan view. Accordingly, the alignment of the marker portion 42 on the biological surface becomes easier.
The marker portion 42 according to the present embodiment is provided at a position adjacent to the receiving portion 6. More specifically, the marker portion 42 according to the present embodiment is adjacent to the receiving portion 6 on a side on which the inflatable portion 8 of the pressing body 4 is located in the plan view of the compression device 1 seen in the thickness direction A. In addition, according to the present embodiment, in the plan view of the compression device 1 seen in the thickness direction A, a maximum width of the marker portion 42 is smaller than a maximum width of the inflatable portion 8 of the pressing body 4. Further, according to the present embodiment, in the plan view of the compression device 1 seen in the thickness direction A, the maximum width of the marker portion 42 is smaller than a maximum width of the extending portion 9 of the pressing body 4. The maximum width of the marker portion 42 according to the present embodiment means a maximum width of the region marker 7a in a width direction B as shown in
According to the present embodiment, in the plan view of the compression device 1 seen in the thickness direction A, the maximum width of the marker portion 42 is smaller than a minimum width of the receiving portion 6. The minimum width of the receiving portion 6 means a minimum width of the receiving portion 6 in the width direction B as shown in

A method for providing the marker portion 42 is not particularly limited, and for example, printing, fusion, adhesion, and integral molding can be used.
At least a part of the marker portion 42 according to the present embodiment is provided at a position between the pair of gripping plate portions 32 in the plan view. Accordingly, the health care worker who operates the compression device 1 can easily and visually identify the marker portion 42 in a state of gripping the pair of gripping plate portions 32 to sandwich the pair of gripping plate portions 32 from two sides. Therefore, an operability of the compression device 1 is improved. More specifically, according to the present embodiment, a part of the region marker 7a and the entire position marker 7b of the marker portion 42 are disposed between the pair of gripping plate portions 32 in the plan view.
The pair of gripping plate portions 32 are gripped by the health care worker. By providing the pair of gripping plate portions 32, the compression device 1 can be easily held. Therefore, it is possible to improve the operability for the health care worker.
Examples of a material of the holding body 5 according to the present embodiment include a resin material. Examples of the resin material include thermoplastic resins used in injection molding such as ABS resin, AS resin, polyethylene, polypropylene, polystyrene, polyvinyl chloride, polyvinylidene chloride resin, polyphenylene oxide, thermoplastic polyurethane, polymethylene methacrylate, polyoxyethylene, fluororesin, polycarbonate, polyamide, acetal resin, acrylic resin, and polyethylene terephthalate, and thermosetting resins such as phenol resin, epoxy resin, silicone resin, and unsaturated polyester.
It is preferable that at least the central portion of the main body portion 31 of the holding body 5 is formed of a material having ultrasonic transmissibility. In addition, it is preferable that the pressing body 4 is also formed of a material having ultrasonic transmissibility. Further, as the fluid supplied to the accommodation spaces 8a of the inflatable portion 8 of the pressing body 4, a fluid having ultrasonic transmissibility such as water or gel is used. Accordingly, an obstructed state of the blood vessel made by the compression device 1 can be detected by an ultrasonic device. The details will be described later.
Next, a method for compressing a biological surface using the compression device 1, the method including an example of a method for adhering the compression device 1 according to this disclosure, will be described.

As described above, the position marker 7b according to the present embodiment is the line segment marker 7b1 that is curved and extends in the arc shape in the plan view seen in the thickness direction A. Therefore, according to the present embodiment, a part of the outer surface of the insertion portion 100a of the medical insertion member 100 is aligned to come into contact with or overlap with the line segment marker 7b1 as the position marker 7b in the plan view. The compression device 1 is attached to the biological surface BS in such an aligned state.

More specifically, when the bleeding is confirmed after the sheaths are removed, the compression force is slowly increased to increase the pressure until the bleeding is stopped. On the other hand, when the bleeding is confirmed to be stopped after the sheaths are removed, the compression force is slowly reduced to reduce the pressure until the bleeding is confirmed. After the bleeding is confirmed, the compression force is slowly increased to increase the pressure until the bleeding is stopped. Accordingly, it is possible to prevent the obstruction of the femoral vein FV (see
Whether the biological surface BS is appropriately compressed may be detected using the ultrasonic device. Specifically, the pressing body 4 and the holding body 5 are formed of a material having ultrasonic transmissibility, and by supplying the fluid having ultrasonic transmissibility such as water to the inflatable portion 8 of the pressing body 4, a compression state made by the compression device 1 can be diagnosed by ultrasounds. That is, the ultrasonic device can detect whether the femoral vein FV (see
By maintaining the compression state for several hours (for example, 2 to 6 hours) as it is, the bleeding can be stopped. After the bleeding is stopped, the compression device 1 is detached from the biological surface BS by releasing the adhesion surface 11 of the adhesive sheet 2 from the biological surface BS.

Therefore, in the compression method, it is preferable to compress the biological surface BS to a position at which a compression depth from the biological surface BS is 5 mm to 20 mm. By setting the compression depth within the above-mentioned range, it is easy to implement the compression state in which the perforations P (see
In the compression method, it is preferable to compress the biological surface BS at 10 g/cm2 to 600 g/cm2 from the biological surface BS. Compression pressure is pressure after the sheath as the medical insertion member 100 is removed, and does not mean the above-mentioned compression force before the sheath is removed. By setting the compression pressure in the above-mentioned range, it is easy to implement the compression state in which the perforations P (see
It is preferable to compress the biological surface BS along a direction orthogonal to an extending direction of the perforations P (see
