Intravenous injection practice arm model

Abstract

The invention relates to an intravenous injection practice arm model. The intravenous injection practice arm model effectively solves the problems that a current venipuncture model has a single function and high use cost. According to the technical scheme, the intravenous injection practice arm model is composed of a hand, a wrist and a small arm, the arm model is internally provided with a main liquid channel and a liquid return channel, the wrist is internally provided with a plurality of rubber tubes, and the wrist can rotate, so that different rubber tubes are connected to the return channel; and the wrist is provided with a liquid branching channel which can be connected in parallel with the rubber tubes, connecting devices which enable the rubber tubes to be connected to the liquid return channel, and the connecting devices can distribute the flow size in the liquid branching channel and the rubber tubes according to the diameter of the rubber tubes. The intravenous injection practice arm model comprehensively and realistically simulates the entire operation process of intravenous injection puncture so that a practitioner can comprehensively practice, the proficiency and adaptability of clinical puncture are improved; and the rubber tubes can be replaced automatically, the arm model is very simple and convenient and can be reused, the cost is greatly reduced, and meanwhile the practitioner gets enough practice.

Description

Technical field [0001] The invention relates to the field of medical teaching, in particular to an intravenous injection practice arm model. Background technique [0002] Intravenous injection is very common in medical work. It is a medical method in which liquid substances such as blood, medicinal solution or nutrient solution are injected directly into the vein. It can directly enter the blood and reach the whole body through the blood circulation. It is the most effective medication. treatment. Medical staff need to master the muscles and vein injections proficiently and need to do a lot of exercises. It is often practiced to practice needles between practitioners, which has great limitations. The practitioners are more painful and cannot practice a lot; although there are intravenous injection models, However, the function is relatively simple and cannot fully simulate various situations of clinical intravenous injection, such as blood vessel thickness, depth, blood pressure...

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 practice arm model for intravenous injection, which effectively solves the problem that the current venipuncture model has a single function, the rubber tube cannot be replaced, and the use cost is high.
