  • the radial artery and the ulnar artery are branched from the brachial artery near the elbow and connected to each other in the palm. For this reason, when only the radial artery is pressed (compressed) for a long time, blood hardly flows into the radial artery, and the blood flow rate of the ulnar artery may excessively increase. As a result, the blood flow volume of the radial artery is reduced, the blood vessel is blocked, and the amount of platelets or the like is reduced, so that it takes a long time to stop bleeding at the puncture site. For this reason, for example, after hemostasis of the puncture site of the radial artery, it is known to press the ulnar artery in order to resume the blocked radial artery (see, for example, Non-Patent Document 1 above).

Abstract

L'invention concerne un instrument hémostatique (10) comprenant : une bande flexible (20) qui peut être enroulée autour d'un bras à travers lequel l'artère radiale (210) et l'artère ulnaire (230) s'étendent ; une partie de fixation (30) qui fixe la bande lorsque la bande est enroulée autour du bras ; une première partie d'expansion (50) qui est reliée à la bande, se dilate lorsqu'elle est remplie d'un fluide, et peut appuyer sur un site où l'hémostase est requise sur l'artère radiale ; et une seconde partie d'expansion (60) qui est disposée dans une position différente, dans la direction longitudinale de la bande, par rapport à la première partie d'expansion, se dilate lorsqu'elle est remplie d'un fluide, et peut appuyer sur l'artère ulnaire. La première partie d'expansion et la seconde partie d'expansion, qui sont espacées l'une de l'autre dans la direction longitudinale de la bande, sont reliées par l'intermédiaire d'un passage de raccordement (170) conçu de telle sorte qu'un fluide peut s'écouler à travers ce dernier.
