Disposable radial artery compression hemostat

Abstract

The invention discloses a disposable radial artery compression hemostat. The disposable radial artery compression hemostat comprises an upper splint, an adjusting air bag, a radius side wrist strap, an ulna side wrist strap, a processus styloideus radii fixing block and a processus styloideus ulnae fixing block, wherein the upper splint is provided with a lug; the adjusting air bag is fixed on the lug; an end of each of the radius side wrist strap and the ulna side wrist strap has a structure matched with a pawl; the middles of the processus styloideus radii fixing block and the processus styloideus ulnae fixing block are recessed; and the processus styloideus radii fixing block and the processus styloideus ulnae fixing block are respectively positioned on the radius side wrist strap and the ulna side wrist strap. The disposable radial artery compression hemostat is characterized in that the radial artery compression hemostat is fixed on a wrist of a patient through the fixing blocks which are adhered to a processus styloideus radii and a processus styloideus ulnae, initial compression is carried out by using the lug, the compression force is adjusted by adjusting the size of the air bag, the wrist straps are fixed in a pawl matching mode, the hemostat is supported by the lug on the upper splint and the two fixing blocks, and compression on other blood vessels and other nerves is avoided. The disposable radial artery compression hemostat is easy to operate, and is fixed reliably and stably; the compression force can be adjusted quantitatively; and compression on the other blood vessels and the other nerves can be avoided.

Description

Technical field [0001] The invention belongs to the field of medical devices, and mainly relates to a disposable compression hemostatic device for radial artery. Background technique [0002] At present, coronary angiography and interventional surgery through the radial artery, peripheral angiography and partial peripheral vascular stent placement have become common approaches. They are easy to compress and stop bleeding after surgery, do not require bed rest, and have fewer postoperative complications. Many advantages, more and more used in clinical surgery. The compression hemostasis technique for the radial artery has been greatly developed in recent years. Initially, manual acupressure or bandage compression was often used to stop bleeding in clinical practice. However, the method of artificial acupressure cannot guarantee the stability of the pressure during the hemostasis process, which may easily lead to failure of hemostasis, which not only increases the work intensity o...

AI Technical Summary

Problems solved by technology

However, since it is necessary to adjust the compression force in the process of hemostasis of the radial artery in clinical practice, so as to avoid complications such as radial artery occlusion, the direct block form adopted by this invention cannot adjust the compression force

At the same time, the support block of this invention is fixed on soft tissues such as skin, which cannot provide a firm and stable fixation, and the hemostat is prone to move.
