Description

A device for fixing and compressing arteries with an arterial indwelling needle

Technical Field

The utility model relates to the technical field of medical supplies, in particular to a matching arterial indwelling needle fixing and arterial compression device.

Background technique

Blood pressure monitoring is one of the important indicators of clinical vital signs monitoring. As a traditional way to measure blood pressure, non-invasive blood pressure monitoring has the advantages of being simple, painless, and safe. However, this method is easily interfered by various factors and affects the accuracy of blood pressure values.

Invasive arterial blood pressure monitoring is a method of directly measuring the intracavitary pressure of the artery after arterial puncture and catheterization. It is not affected by external factors such as artificial pressurization, decompression, cuff width and tightness, and is accurate and intuitive. It can detect instantaneous changes in arterial pressure in a timely manner. Arterial blood can be taken for blood gas analysis. Therefore, it is widely used in the field of emergency, cardiovascular surgery, neurosurgery and intensive care units, especially in surgical anesthesia. The sampling site is mostly the radial artery of the upper limb or the dorsalis pedis artery of the lower limb, and it is easy to use, safe and reliable.

However, in the intensive care unit, most patients are in a state of unclear consciousness, irritability, and coma. During invasive arterial blood pressure monitoring, the arterial needle may be dislocated or even dislocated due to the patient's restlessness or improper care, which may lead to unstable blood pressure monitoring and bleeding in mild cases, and acute bleeding in severe cases. If not discovered in time, it may be life-threatening. In addition, after the arterial monitoring is completed, it is usually necessary to press the arterial puncture site for a long time. Manual pressure is best, but it will increase the manpower burden and is time-consuming. Traditional elastic bandages have problems of insufficient pressure and easy loosening, which can cause bleeding.
