CN-117119977-B - Hemostatic instrument

Abstract

Provided is a hemostatic instrument (110) which can effectively apply compression force to puncture sites (p 1-p 4) even when hemostasis is performed on puncture sites (p 1-p 4) formed at predetermined positions of the index finger metacarpal bone (B1) of a hand (H) and the thumb metacarpal bone (B2) of the hand. The hemostatic instrument (100) comprises a support member (110) configured to cover a1 st puncture site (p 1), a fixing member (120) configured to fix the support member (110) to the 1 st puncture site (p 1), and an expansion member (180) connected to the support member (110) and configured to press the 1 st puncture site (p 1), wherein the rigidity of the support member (110) is greater than the rigidity of the expansion member (180). The width (W) of the support member (110) is narrowed from the upper end (111) toward the lower end (112). The thickness of the side surface portion (113) of the support member (110) decreases from the upper end portion (111) toward the lower end portion (112).

Description

Hemostatic instrument Technical Field The present invention relates to hemostatic devices. Background As one of catheter operations, there is known a catheter operation in which various medical long-length bodies are introduced into blood vessels through a puncture site formed by puncturing blood vessels of limbs such as arms and hands of a patient, and treatment and therapy are performed on a lesion site. For example, patent document 1 discloses a hemostatic instrument that can stop bleeding at a puncture site formed so as to be able to reach a blood vessel (including a distal radial artery) that runs on a hand. The hemostatic instrument of patent document 1 includes a pressing member that applies a pressing force to a puncture site (hereinafter, also simply referred to as "puncture site") formed in a patient's hand, a band that fixes the pressing member to the patient's hand, and a support member that is disposed in the band and presses the pressing member against the patient's hand. The band includes a1 st band disposed between the fingers of the patient and a2 nd band wound around the forearm portion of the hand of the patient. Prior art literature Patent literature Patent document 1 U.S. patent application publication No. 2019/0133702 specification Disclosure of Invention When an operator such as a doctor (hereinafter referred to as "operator") forms a puncture site on a hand, the puncture site is set at a predetermined position where the metacarpal bone of the index finger of the hand and the metacarpal bone of the thumb of the hand are avoided. By setting the puncture site at such a predetermined position, the operator can prevent the puncture instrument such as the indwelling needle from interfering with the metacarpal bone of each finger when forming the puncture site. However, when the puncture site is formed at a predetermined position avoiding the metacarpal bones of the index finger and thumb, the following problem occurs when the hemostatic instrument described in patent document 1 is used for hemostasis. When the operator performs hemostasis on the puncture site, the pressing member and the support member of the hemostatic instrument of patent document 1 are disposed so as to overlap the puncture site. When an operator disposes the hemostatic instrument of patent document 1 on the hand of a patient, the support member may be placed on the metacarpal bone of the index finger and the metacarpal bone of the thumb. When the hemostatic instrument of patent document 1 is wound around the hand of the patient with the support member disposed on the hand of the patient as described above, a gap is formed between the pressing member and the hand, and the 2 nd band cannot be fitted along the outer periphery of the hand of the patient. In this state, the 1 st band of the hemostatic instrument of patent document 1 is strongly tightened, whereby the pressing member and the support member can be firmly fixed to the hand of the patient. On the other hand, in this case, the 1 st band of the hemostatic instrument of patent document 1 needs to be strongly tightened, and thus pain may occur in the patient. Therefore, in the hemostatic instrument of patent document 1, when tightening of the 1 st belt body cannot be forcibly performed due to pain or the like of the patient, the support member is disposed from the fingertip side of the hand toward the forearm side so as to be inclined in a direction approaching the surface of the hand. When the support member is disposed in the hemostatic instrument of patent document 1 as described above, the pressing member cannot apply a pressing force in a vertical direction to the puncture site. Thus, the hemostatic instrument of patent document 1 cannot effectively apply a pressing force to the puncture site. In view of the above-described problems, an object of the present invention is to provide a hemostatic instrument capable of effectively applying a pressing force to a puncture site formed at a predetermined position avoiding the metacarpal bone of the index finger of a hand and the metacarpal bone of the thumb of the hand, even when hemostasis is performed. The hemostatic instrument of the present invention comprises a support member configured to cover a puncture site formed in a patient, a fixing member configured to fix the support member to the puncture site of the patient, and a pressing member configured to be connected to the support member and to press the puncture site of the patient, wherein the support member has an upper end portion, a lower end portion, and a side surface portion, and has a rigidity greater than that of the pressing member, the upper end portion is located on a distal end side of the pressing member, an end portion of the support member is formed, the lower end portion is located on a proximal end side of the pressing member, an end portion on an opposite side to the upper end portion is formed, the side surface portion connects the upper e
