Far-end radial artery tourniquet and far-end radial artery hemostat

Abstract

The invention provides a far-end radial artery tourniquet and a far-end radial artery hemostat. The far-end radial artery tourniquet and the far-end radial artery hemostat are used for compression hemostasis of puncture points after far-end radial artery paracentesis, wherein the far-end radial artery tourniquet comprises a compression air bag and at least three fixing bands, one ends of the at least three fixing bands are sequentially connected to the periphery of the compression air bag, the other end of each fixing band is provided with a connecting piece which is used for being connected with other fixing bands to fix the compression air bag during the compression hemostasis. According to the far-end radial artery tourniquet and the far-end radial artery hemostat, during the compression hemostasis, the fixing bands can conform to a hand shape to fix the compression air bag, the fixing effect is good, and a patient wears the far-end radial artery tourniquet and the far-end radial artery hemostat comfortably.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a distal radial artery tourniquet and a distal radial artery hemostat. Background technique [0002] The distal radial artery puncture technique is a new interventional puncture technique developed in recent years. It is a new interventional approach and an effective supplement to the conventional approach. According to the clinical practice in recent years, this technique has been used in some cases (including but not limited to: when conventional radial artery puncture fails (spasm, hematoma, etc.), radial artery pulse is unclear during the second interventional operation, bilateral radial artery When dealing with CTO, or acute and chronic occlusion of the radial artery), it is more operable and safer than the traditional radial artery puncture; at the same time, because the patient's hand can be naturally placed on the abdomen during the operation, it brings better com...

Problems solved by technology

However, for the distal radial artery puncture technique, because the distal radial artery puncture point is located in the hand, the surrounding hand structure is obviously tapered, resulting in that the existing radial artery hemostat products cannot be stably fixed at the puncture point, which in turn leads to There is no convenient hemostatic equipment available for posterior hemostasis, and the operator can only use the most primitive bandage winding method to stop bleeding

However, this method of hemostasis has the disadvantages that it is impossible to observe the bleeding point, the hemostatic effect cannot be accurately judged, the tightness should not be adjusted, it relies too much on the experience of the surgeon, and it is more likely to cause postoperative complications.
