Deformed example 1

[0098] Figure 6 It is a diagram provided for explaining the hemostatic device 100 according to Modification 1.

[0099] The hemostatic device 100 according to Modification 1 differs from the above-mentioned embodiment in the arrangement position of the filter member 170 .

[0100] Specifically, as Figure 6 As shown in (A), the filter member 170 is arranged on the outer surface side of the support plate 21 in the area of ​​the support plate 21 where the hole portion 24 is provided. In addition, the filter member 170 is comprised by the asymmetric membrane provided with the porous layer 71 and the skin layer 72 similarly to the said embodiment.

[0101] A recessed portion 121d recessed from the outer surface side toward the inner surface side is formed in a region of the support plate 21 where the filter member 170 is disposed. and, if Figure 6 As shown in (B), the filter member 170 is arranged on the outer surface of the support plate 21 so that the skin layer 72 enters ...

Deformed example 2

[0105] Figure 7 It is a diagram provided for explaining the hemostatic device 200 according to Modification 2.

[0106] The hemostatic device 200 according to Modification 2 is different from the above-mentioned embodiment in the configuration of the expansion part 240 .

[0107] The expansion part 240 includes a first pressing part 241 for pressing the puncture site P, and a second pressing part 242, which is arranged between the first pressing part 241 and the support plate 21, and the first pressing part 241 The direction of the applied pressing force is adjusted to the direction toward the puncture site P. As shown in FIG.

[0108] The first pressing portion 241 is formed by overlapping two substantially rectangular sheets and forming it into a bag shape. Like the above-mentioned expansion part 40, the first pressing part 241 is connected to the injection part 60 (not shown in the figure). It should be noted that the configuration of the first pressing portion 241 is n...

Deformed example 3

[0113] Figure 8 It is a diagram provided for explaining the hemostatic device 300 according to Modification 3.

[0114] The hemostatic device 300 according to Modification 3 differs from the above-described embodiment in the shape of the hole 324 provided in the support plate 21 .

[0115] Such as Figure 8 As shown in (B), the hole portion 324 has a shape tapered from the inner surface side of the support plate 21 toward the outer surface side in the cross section along the thickness direction of the support plate 21 . Therefore, by maintaining a large contact area between the filter member 70 and the hole 324 , good air permeability can be maintained, and the intrusion of foreign matter into the hole 324 from the outer surface side to damage the filter member 70 can be suppressed well.

[0116] In addition, the corner portion 324 r on the inner surface side of the support plate 21 forming the hole portion 324 has a shape with an arc. Therefore, it is possible to satisfac...

Abstract

An object of the present invention is to provide a hemostatic device capable of maintaining the strength of the expanded portion well and easily adjusting the discharge rate of gas. The solution of the present invention is: a hemostatic device (10), which has: a belt (20), which is used to wrap around the puncture site P of the wrist W; fixed in the state; the expansion part (40), which is connected with the belt body, and expands by injecting gas; and the filter member (70), which controls the discharge of the gas injected into the expansion part, wherein the belt body has more than one A hole (24), the hole passing through between the inner surface and the outer surface of the belt, the expansion part is arranged in a manner covering the hole in the inner surface of the belt, and the filter member is arranged in the belt so as to block the hole. body, and inhibit the gas from being discharged from the hole.

Description

technical field [0001] The present invention relates to a hemostatic device for compressing a punctured site for hemostasis. Background technique [0002] In recent years, blood vessels such as arms and legs are punctured, an introducer sheath is introduced into the puncture site, and medical devices such as catheters are delivered to the lesion through the lumen of the introducer sheath. Percutaneous treatment and examination, etc. . When performing such treatment, inspection, etc., the operator needs to stop bleeding at the puncture site after removing the introducer sheath. In order to carry out this hemostasis, there is known a hemostatic device equipped with the following parts: a belt body, which is used to be wrapped around limbs such as arms and legs; a fixing member, which fixes the belt body in a state wound around the limb; , which is attached to the band and expands by injecting fluid, compressing the puncture site. [0003] In such a hemostatic device, when t...
