Hand back vein infusion model

Abstract

The invention provides a hand back vein infusion model. The hand back vein infusion model is composed of a disposable rubber surgical glove and a three chamber catheter, the disposable rubber surgical glove simulates a human arm, the tube body of the three chamber catheter is bent and coiled to form a hand back vein part, the hand back vein part is arranged on the outer end surface of the hand back of the disposable rubber surgical glove, and the end of the back vein part is closed; the three chamber pipe part of the three lumen catheter is arranged on the outer end face of the arm of the disposable rubber surgical glove, the three chamber pipe part includes a liquid inlet pipe and a liquid outlet pipe, and the other pipe opening is treated to be closed; and the end of the liquid inlet pipe communicates with a liquid storage bag, and the end of the liquid outlet pipe communicates with a drainage bag. According to the hand back vein infusion model, the cost of the hand back vein infusion model is low, manufacturing is simple, and the structure is clear, the reuse of medical wastes is further realized, and therefore, the hand back vein infusion model has wide application prospects.

Description

technical field [0001] The invention belongs to the technical field of medical models, in particular to a dorsal hand vein transfusion model. Background technique [0002] At present, intravenous infusion is a commonly used clinical treatment method. Therefore, in clinical nursing, giving patients acupuncture and infusion is a basic skill that medical staff must master. Typically, medical schools use mannequins or live practice or a combination of both to teach this skill, however, for beginners, arm infusion models are often used as the primary means of practice. [0003] The arm infusion model uses silica gel, latex, mixed glue and other materials to simulate muscles, skin and blood vessels on the back of the hand, and makes a single arm for intravenous infusion teaching. Students can use this model to practice repeatedly. However, most of the existing intravenous infusion arm models are large in size and complex in structure. At the same time, the skin of the intravenous...

AI Technical Summary

Problems solved by technology

However, most of the existing intravenous infusion arm models are large in size and complex in structure. At the same time, the skin of the intravenous infusion arm model is fully enclosed, and the injected liquid cannot be discharged after puncture. After repeated practice, the simulated blood vessels cannot be replaced, causing the entire model to be scrapped.

Moreover, the model is expensive, and the quantity purchased by colleges and universities is small, which may easily lead to insufficient proficiency of students in practice.
