Pressure monitoring apparatus for artery compressing hemostasis

Abstract

A pressure monitoring apparatus for artery compressing hemostasis comprises a water bag and a transparent air storage pipe, wherein the transparent air storage pipe has pressure scale marks indicating the pressure born by the water bag. When the water bag is squeezed, liquid inside the water bag enters the transparent air storage pipe and forms a water column; the water column seals the air at one end; and by measuring the pressure born by the water bag during an artery compressing hemostasis process and marking the length of the water column entering the transparent air storage pipe, the pressure magnitude during the artery compressing hemostasis process can be reflected in a quantitative manner according to the pressure scale marks on the transparent air storage pipe. When in use, the apparatus is placed under an artery compressed part dressing bandage or inside an interlayer under an artery compressor hard plastic plate; pressure is exerted on the water bag through an external compressing device until the water column reaches a target pressure scale mark on the transparent air storage pipe; quantitative monitoring of the pressure magnitude during the artery compressing hemostasis process is achieved; and the dressing tightness is made easier to control.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a pressure monitoring device for arterial compression and hemostasis. Background technique [0002] In the field of cardiovascular and cerebrovascular diseases, with the improvement of medical level, digital subtraction angiography or percutaneous coronary intervention is a very effective and mature medical method, and has become the main method for diagnosing and treating cardiovascular and cerebrovascular diseases. One of the methods. Angiography and interventional therapy can be performed via the arterial route. Interventional examination and treatment are still invasive procedures, and postoperative arterial compression and hemostasis are required. Traditional pressure hemostasis uses bandages to wrap multiple layers of gauze or artificial fingers to press the puncture point, which requires high skill and experience of the operator, often resulting in failure of hemostasis and...

Problems solved by technology

However, there are some disadvantages in both gauze bandage and device compression: the tightness of the bandage is not easy to control, if it is too loose, the compression will be ineffective, easy to bleed or hematoma; if it is too tight, it will affect the return of venous blood, causing numbness and swelling , congestion, etc.
