An intravenous injection simulation teaching device

Abstract

The invention relates to an intravenous injection simulation teaching device, which effectively solves the problem of single function and high cost of use of the current venipuncture model; the technical solution includes an arm model composed of a hand, a wrist and a forearm; the arm model There are a main liquid channel and a liquid return channel inside. There are multiple rubber tubes and a branch liquid channel in the wrist. The wrist can be rotated so that different rubber tubes can be connected to the return channel. The connection device of the liquid channel connection tube, the connection device can adjust the flow rate of the branch liquid channel according to the diameter of the rubber tube; the invention fully and realistically simulates the entire operation process and various situations of intravenous injection puncture, enabling practitioner It can be practiced comprehensively, which improves the proficiency and adaptability of clinical puncture, and the rubber tube can be replaced by itself, which is very simple and convenient, and can be reused, so that the practitioner can get enough practice while greatly reducing the cost.

Description

technical field [0001] The invention relates to the field of medical teaching, in particular to an intravenous injection simulation teaching device. Background technique [0002] Intravenous injection is very common in medical and nursing work. It is a medical method that directly injects liquid substances such as blood, medicinal liquid or nutrient solution into the vein. It can directly enter the blood and reach the whole body through blood circulation. It is the fastest-acting drug. treatment. Medical personnel need a lot of practice to master the tendon injection proficiently. Often practitioners practice acupuncture with each other, which has great limitations. The practitioner is more painful and cannot practice a lot; although there are intravenous injection models, However, the function is relatively single, and it cannot fully simulate various situations of clinical intravenous injection, such as the thickness, depth, blood pressure, bending and swimming of blood v...

AI Technical Summary

Problems solved by technology

[0003] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a simulated teaching device for intravenous injection, which effectively solves the problem that the current venipuncture model has single function, the rubber tube cannot be replaced, and the use cost is high.
