Description

Technical Field

[0001] The invention belongs to the field of arterial puncture instruments, and in particular relates to an arterial puncture positioning needle insertion auxiliary device. Background Art

[0002] Arterial puncture is a key medical method that aims to penetrate the artery with a puncture needle to serve a variety of medical needs, including blood gas analysis, arterial catheterization, blood pressure monitoring and interventional treatment, etc. It is an indispensable part of clinical diagnosis, emergency treatment and drug administration. Given the shallow location of the radial artery and femoral artery, the high puncture success rate and low risk of complications, they have become the preferred sites for arterial puncture.

[0003] In order to improve the success rate of arterial blood sampling, a variety of methods have been developed in clinical practice, such as direct touch method, quarter joint touch method, "cross" positioning method, visual method and direct vision method. However, these methods are easily interfered by subjective judgment, difficulty in touching the artery, and patient agitation due to pain, which makes it difficult for doctors to accurately perceive the pulse point, and the needle may blindly shuttle in the skin, increasing the risk of bruising, bleeding, hematoma, infection and thrombosis at the blood collection site.

[0004] In addition, individual differences in arterial anatomy and patient characteristics (such as obesity, hypotension, etc.) pose challenges to the selection of puncture sites and the determination of puncture angles. These are highly dependent on the operator's clinical experience, making it difficult to accurately identify, display, and fixate arteries.

[0005] The invention with publication number CN118453055A discloses an auxiliary device for arterial puncture positioning. Although the device locates the artery through laser and vibration detector, it is very inconvenient to perform arterial puncture. After the positioning is completed, the entire laser detection part of the device needs to be lifted upward, and then the laser is used to locate the artery after it is lifted. In this way, not only will there be instability in the lifting process of the laser detection part, resulting in inaccurate laser positioning, but medical personnel still need to perform puncture with a puncture needle, which still requires heavy reliance on the clinical experience of medical personnel and still cannot ensure the success rate of arterial puncture.

[0006] The invention with publication number CN109998649A discloses an arterial puncture auxiliary positioning device. Although the device fixes the artery by pressing down with a fixed clamping block after the artery is successfully positioned, the artery is often accompanied by multiple veins and is easy to slide. The device cannot accurately control the clamping to the predetermined artery. Moreover, the device fixes the artery with a clamping block, which can easily cause the entire device to slide on the surface of the human body. However, the device has no design to prevent sliding, and the device still requires medical personnel to perform puncture with a puncture needle. Since the arterial wall is thick and elastic, relying solely on medical personnel for puncture will greatly reduce the success rate of arterial puncture. Summary of the invention
