Description

An adjustable pressure inflatable hemostatic device

technical field

The utility model belongs to the technical field of medical devices, in particular to an adjustable pressure inflatable hemostatic device.

Background technique

With the development of vascular interventional therapy, in clinical practice, many types of operations require arterial or venous puncture, such as implantation of peripheral central venous catheters, balloon catheter dilation, and stent implantation. However, after the puncture, about 2mm of blood vessels will be damaged, and bleeding needs to be stopped.

In the process of hemostasis, the hemostasis site should be compressed accurately and effectively; if the pressure is too large, it will affect the blood flow under the skin, causing numbness and poor blood flow in the compressed part of the patient, and even nerve damage in severe cases; If the pressure is insufficient, bleeding, oozing, etc. are prone to occur. Although new types of tourniquets have appeared, there are still some technical defects. For example, the pressure of the tourniquet on the puncture site remains unchanged after bandaging. If the patient is uncomfortable, it cannot be adjusted by itself, and additional medical staff is required to perform the operation, which not only increases the work intensity of the medical staff, but also is not conducive to the patient's health. experience. In addition, the existing inflatable tourniquets are generally disposable, resulting in a waste of resources.

Therefore, it is necessary to develop an adjustable pressure inflatable hemostatic device, which is used to accurately and effectively stop the bleeding at the hemostasis site, and at the same time brings comfort to the patient, and can be reused without causing a waste of resources.
