Description
Technical field
The utility model relates to the built-in blood circulation device of a kind of emulation venous transfusion, belongs to medical educational device field.
Background technology
The present medical worker of China or to defend the school student all be to use true man's practical operation when the injection of exercise hand back vein, particularly defending the school student all practises the other side mutually on hand, this brings very big misery for the person of being injected, and also makes operator's stress, and practice effect is had a greatly reduced quality.In order to address this problem, emulation venous transfusion arm has now appearred on the market, and its adopts medical latex to make, and directly emulation vein and vein is made on the arm, is contained in the box, and a liquid storage capsule is housed on the lid.When simulation transfusion exercise, open the lid, liquid storage capsule position raises, and pattern is intended the gravity of blood plasma with the emulation venous engorgement on the back of the hand, can carry out puncture procedure.This teaching aid only can only be done the venipuncture exercise, and have the following disadvantages: the ⑴ manufacture difficulty is big, and cost is higher, and the market price of an emulation venous transfusion arm is on average at 1500 yuan～3000 yuan, and therefore puncture whole the arm in back several times is not used for practising with regard to subscription rate substantially; ⑵ it does not need to make and tightens the operation of tourniquet and tourniquet released, can not observe automatic blood back phenomenon in the vein blood vessel even if puncture needle penetrated, and more can not carry out drip-feed (transfusion) and practise.Therefore misfit with the standard operation of reality, be unfavorable for student's formal training; ⑶ the degree true to nature of rete venosum is poor, because rete venosum and emulation arm are made of one, also just is not easy very meticulous on the mould process.
In order to address the above problem, the utility model people had once proposed the patented claim of " global function emulation venous transfusion arm " (application number 200820199878.2).But the degree true to nature of the exercise of this device operation with true man's operation is also had gap, liquid can enter reservoir and water down simulation blood plasma during transfusion, needs frequent replacing just can see to come in and go out the blood back behind the pin, makes the operation trouble that becomes, and can increase the exercise cost; After entering certain quantity of fluid in the reservoir, infusion flow rate can slow down, even can stop, being unfavorable for the student judge oneself whether go into the pin position suitable; This device is the simulation arm, is not suitable for extensively practising the intravenous injection of other position.
Summary of the invention
Technical problem to be solved in the utility model provides the built-in blood circulation device of a kind of emulation venous transfusion, its structure order, and easy to operate, simulation degree is more true to nature.
Solving the scheme that technical matters of the present utility model adopts is: at reservoir one termination emulation venous blood pipe network, rete vasculosum connects the reservoir other end by recirculatory pipe, and it is parallel with reservoir to be positioned at the other recirculatory pipe of reservoir, also be connected to an isocon A in the side at recirculatory pipe, be provided with the retaining valve of outflow in the outlet of reservoir, be provided with the retaining valve of inflow at the entrance of reservoir.
Inlet end at reservoir is respectively arranged with liquid-feeding tube and gas outlet, and the entrance of liquid-feeding tube is provided with the retaining valve of inflow.
Insert liquid-feeding tube in the other position that connects the isocon I of recirculatory pipe by an isocon II, be provided with retaining valve in the isocon II, the retaining valve of the entrance of reservoir is arranged on the endpiece of liquid-feeding tube.
Principle of work of the present utility model: 1. open exhaust valve and gas outlet, in reservoir, fill it up with simulation blood plasma by liquid-feeding tube, close exhaust valve again.2. tighten tourniquet, blocking-up recirculatory pipe when reservoir is pressurizeed, meanwhile the retaining valve of reservoir entrance is blocked, the retaining valve of reservoir outlet is opened, and the retaining valve of isocon II and liquid-feeding tube liquid-feeding tube inlet one-way valve are closed, the pressure transfer that be applied on the reservoir this moment has arrived on the rete vasculosum, its pipe internal pressure is raise, just visible blood-back when pin correctly thrusts rete vasculosum, remove the pressure of reservoir, recirculatory pipe is unimpeded simultaneously, because reservoir reset generation negative pressure, can make the closed check valve of reservoir outlet, and the one-way valve opens of the retaining valve of reservoir entrance and isocon II, the simulation blood plasma in the pipe is by recirculatory pipe, the isocon II flows back to reservoir again.When in rete vasculosum, infusing, the closed check valve of reservoir outlet under infusion pressure at this moment, the flow direction recirculatory pipe is because the retaining valve on the isocon II has certain resistance, so transfusion fluid can flow to the little isocon I of resistance.3. the circulation of simulation blood plasma is only carried out can not entering the isocon I between reservoir and rete vasculosum and is run off.Liquid only flows to the isocon I and can not enter reservoir and water down simulation blood plasma during transfusion.4. as in that the isocon I is terminal connect a liquid storing bag and just can carry out endless transfusion, and the blood back effect when not influencing continuous puncture exercise.
Useful technique effect of the present utility model is: this built-in blood circulation device is reasonable in design, fidelity is higher, can be advantageously used in the venous blood pipe network of diverse location, be conducive to the student and learn technique drills such as clinical vein puncture, transfusion, blood transfusion, vein haemospasia, venous detaining needle operation more realistically, can offer the personal understanding of practitioner's true operation, meet the standard operation requirement of clinical arm venipuncture, transfusion, blood transfusion, remaining needle, vein haemospasia fully.
