Ultrasound-guided radial artery puncture practice device

Abstract

The invention discloses an ultrasound-guided radial artery puncture practice device, characterized in that the device includes a body model, an infusion tube, an imaging mechanism and a reciprocatingmechanism for pushing a liquid in the infusion tube to flow. The infusion tube is arranged in the body model in a penetrating manner, and after two ends of the infusion tube are connected to form a closed loop, the reciprocating mechanism is connected with the infusion tube, and the imaging mechanism is connected with the body model. The arrangement of the reciprocating mechanism enables the liquid in the infusion tube to flow to simulate blood flowing in a human body, so that the device has better simulation effect. The arrangement of the infusion tube simulates blood vessels in the skin of the human body. By using the imaging mechanism, a practicer is able to clearly see the shape and location of a puncture needle so as to enable the puncture needle to enter the infusion tube rapidly andaccurately. By practice and use of the device, an existing conventional ultrasound puncture device in medicine can be used skillfully.

Description

technical field [0001] The invention belongs to the medical field, in particular to a radial artery puncture practice device guided by ultrasound. Background technique [0002] Puncture is a commonly used surgical term in medicine. It is a diagnosis and treatment technique in which a puncture needle is inserted into a body cavity to extract secretions for testing, injecting gas or contrast agent into the body cavity for contrast examination, or injecting drugs into the body cavity. The purpose of puncture is blood test, blood transfusion, infusion and catheter placement for angiography, etc.; the traditional puncture process mostly adopts blind puncture, but blind puncture requires high proficiency of the operator and often requires multiple attempts To be successful, multiple punctures may cause bleeding or arterial spasm, causing discomfort to the patient. [0003] The radial artery is the peripheral artery most commonly selected for arterial puncture and catheterization ...

AI Technical Summary

Problems solved by technology

However, for beginners, ultrasound-guided arterial puncture and catheterization are very difficult to operate, and it is difficult to puncture successfully at one time. Repeatedly adjusting the position and angle of the puncture needle will cause great damage to the patient.
