Description

Technical Field

[0001] The utility model relates to the technical field of medical appliances, in particular to a pressurized hemostatic fixing belt. Background Art

[0002] Arterial and venous puncture and catheterization technology is an important diagnostic and treatment technology widely used in critical care medicine. Arterial puncture and catheterization are often used to continuously monitor arterial blood pressure and perform special examinations or treatments such as blood gas analysis and hemodialysis treatment for critically ill patients. Due to the high arterial pressure, the puncture site of arterial puncture and catheterization often requires 10 minutes or even longer compression. In order to reduce the workload of staff, a hemostatic fixation belt is generally needed to control bleeding and fix wounds. It is usually made of elastic material, can fit closely to the skin surface, and exert appropriate pressure to help stop bleeding.

[0003] As in the prior art, the Chinese patent authorization number is CN217525272U, the application date is: 2022-02-09, and the name is a pressurized hemostatic fixation belt after radial artery puncture in the cardiovascular department, comprising a support frame, a through groove is provided on the support frame, a fixing component is installed on the support frame, a fixing belt body is installed on the side of the support frame, one end of the fixing belt body is installed in the through groove through the fixing component, an airbag is fixedly installed on the lower surface of the fixing belt body, a ventilation tube is installed on one side of the airbag, and a pressurized sphere is fixedly installed on the end of the ventilation tube away from the airbag. The utility model can press the pressurized sphere to flush air into the airbag. After flushing air into the airbag, the airbag will swell up, thereby applying pressure to the fixing belt body, so that the fixing belt body is urgently fitted to the patient's bleeding-requiring part, thereby achieving a hemostatic effect, so that the tightness of the fixing belt can be adjusted at will.

[0004] However, the above patent still has the disadvantage that, when the fixing belt is worn, the medicine portion often needs to be aligned with the puncture site. However, since the position of the pressure cannot be adjusted, it is impossible to better and more closely fit the medicine portion to the patient's puncture site, which can easily cause a loose fit and inadequate treatment and bleeding, further reducing the hemostatic effect.

[0005] Therefore, in response to this problem, the utility model provides a pressurized hemostatic fixing band. Utility Model Content
