Simulated blood vessel puncture simulation training device

Abstract

The invention provides a simulated blood vessel puncture simulation training device, a simulated blood vessel is pre-buried in a human tissue module and liquid is injected into the simulated blood vessel through pressurization; during puncture training, simulated human body tissue is observed through ultrasonic waves, a needle tip is inserted from a skin layer of the simulated human body tissue, and the needle tip is guided to be inserted into the simulated blood vessel through an ultrasonic display panel; and when the needle tip is inserted into the simulated blood vessel and due to the factthat simulated blood is injected into the simulated blood vessel through pressurization by a liquid storage bag, the simulated blood flows back into a needle tube through the needle tip, and the training personnel can clearly know that the puncture is completed through the ultrasonic waves and observation of the backflow of the blood. According to the puncture simulation training device in the invention, animal tissue is adopted as a puncture simulation module, due to the same as the human body tissue, the degree of simulation is improved, the pinholes are not obvious even through repeated puncture, and the fidelity of puncture training is improved as the feeling of touching the blood vessel under the skin layer by hands and the falling feeling of needle injection are similar to a real person during puncture.

Description

technical field [0001] The invention relates to the technical field of medical teaching, in particular to a puncture training device, in particular to a simulated blood vessel puncture simulation training device. Background technique [0002] Vascular puncture is a common and widely used technology in modern medicine. It is used in various clinical operations such as interventional surgery, deep vein catheterization, PICC catheterization, puncture and blood drawing. Skilled puncture operators can greatly shorten puncture time and reduce puncture complications, but it takes a lot of practice to become a skilled puncture operator. [0003] Existing puncture practice molds generally use simulation modules made of silica gel. Blood vessels are simulated inside the simulation module. The practitioner holds a needle to perform puncture training on the simulation module. After a long period of training, it can quickly improve the trainer's puncture proficiency; However, since the ...
