Description

Hand back venous transfusion model

Technical Field

The utility model belongs to the technical field of medical model, concretely relates to back of hand venous transfusion model.

Background

At present, intravenous infusion is a clinical common treatment method, so in clinical nursing, the injection and infusion of a patient are basic skills to be mastered by medical care personnel. In general, each medical institution teaches the skill by model teaching or real person practice or a combination of both, however, arm infusion models are commonly used as the main means of practice for beginners.

The arm transfusion model simulates muscle, skin and back blood vessels by using materials such as silica gel, latex, mixed glue and the like, a single arm is manufactured for venous transfusion teaching, and students can use the model for repeated practice. However, most of the existing intravenous infusion arm models are large in size and complex in structure, and meanwhile, the skin of the intravenous infusion arm model is totally enclosed, so that liquid input after puncture cannot be discharged, and after multiple times of practice, the simulated blood vessels cannot be replaced, so that the whole model is scrapped. And the model is expensive, the number of purchased universities is small, and the proficiency of student practice is easy to be insufficient.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems existing in the prior art, the utility model aims to provide a back of hand venous transfusion model, which uses cheap waste materials for manufacturing, reduces the manufacturing cost of the model and improves the exercise effect of students.

In order to achieve the above object, the present invention provides the following technical solutions:

a back of hand venous transfusion model, the said venous transfusion model is made up of disposable rubber surgical glove and three-chamber urethral catheter, the said disposable rubber surgical glove imitates the human arm, the tube body of the said three-chamber urethral catheter bends and coils and forms the back of the hand vein part, the said back of the hand vein part is set up in the outer end of back of the hand of the disposable rubber surgical glove, the end of the said back of the hand vein part is sealed; the three-cavity tube part of the three-cavity catheter is arranged on the outer end face of the arm of the disposable rubber surgical glove, the three-cavity tube part comprises a liquid inlet tube and a liquid outlet tube, and the other tube opening is subjected to sealing treatment; the tail end of the liquid inlet pipe is communicated with a liquid storage bag, and the tail end of the liquid outlet pipe is communicated with a drainage bag.

Furthermore, the end of the liquid inlet pipe is provided with a first one-way valve connected with the liquid storage bag, and the end of the liquid outlet pipe is provided with a second one-way valve connected with the drainage bag.

Furthermore, the tail end of the drainage bag is provided with a drainage port, and a spiral cap or a cross valve is arranged on the drainage port.

Furthermore, one side of the drainage bag, which is opposite to the drainage port, is provided with a suspension rope.

Furthermore, the reservoir is an extrusion type flushing ball.

Has the advantages that: the utility model provides a back of hand venous transfusion model, this infusion model adopt dumped disposable rubber surgical gloves and three chamber catheter preparation to form, and disposable rubber surgical gloves simulates human arm, and three chamber catheter simulation blood vessel net feeds through reservoir and drainage bag on the three chamber catheter for the normal input and the output of liquid, and through the flow of check valve control liquid. The venous transfusion model has low cost, further realizes the reutilization of medical wastes, has the price of only one hundredth of the price of a commercially available model, and greatly saves the purchase cost of institutions. The venous transfusion model is simple to manufacture and clear in structure, and can be manufactured by students, so that the number of times of student exercises is increased, and proficiency is further provided. Therefore, the venous transfusion model of the utility model has wide application prospect.
