Description
Technical field
The utility model relates to medical teaching field, particularly relates to a kind of device of simulating venipuncture, blood sampling and transfusion.
Background technology
Existing model is the puncture of simple hand back vein, infusion model on the market; For having dorsal venous rete of hand and elbow venipuncture, transfusion two functions have simultaneously, do not have finding; Student, when doing veins of upper extremity puncture procedure, should bind tourniquet, touches vein (now simulated blood vessel is full state), then puncture with hand.At present, mechanical type infused-arm (without power supply), electronic type infused-arm (internal electric source), electronic type infused-arm (external power source) is divided on the market; Infused-arm model on the market, only has dorsal venous rete of hand, or containing forearm; Judging puncture whether success, lean on be the other end of pin transparent pipe on whether have blood back phenomenon to produce; This blood back phenomenon, only not opening the water on woven hose, should not disappear; After unlatching, blood back phenomenon just can disappear; Infused-arm is in the past after first student is totally lost liquid, and after needing artificial the interference, second student just can use.If artificially do not interfered, when second student operates, whether the liquid stopped in puncture pipeline, puncture and correctly just cannot judge whether student operates correctly.
Summary of the invention
The purpose of this utility model is to provide a kind of device of medical lecture model, provides medical worker or student to simulate the teaching mode of the puncture of true man's veins of upper extremity, blood sampling, transfusion operation exercise; Without external switch, by clinical manipulation program, when binding tourniquet, contact microswitch, can operate.
The technical scheme that the utility model adopts is, a kind of simulation vein puncture device, is characterized in that, comprise power pump, simulated blood vessel, electric supply installation and microswitch.
Wherein, described simulated blood vessel is connected with power pump, forms loop, when power pump works, outside liquid can be pumped in simulated blood vessel, and controls to form certain pressure.
Described electric supply installation, microswitch are connected with power pump; Microswitch is used for unlatching and the stopping of control pump.
Described pump is provided with inlet and leakage fluid dram, is respectively arranged with plug, prevent leakage.
Described electric supply installation can be external power source, also can be internal electric source.
The beneficial effects of the utility model are, can Full-functional artificial systemic vein infusion model; Emulation property is high, can connect other models; Simple circuit structure, failure rate is low; Inside is dc-battery, and security is higher; By clinical vein puncture, blood sampling, transfusion operation step, real simulation exercise can be carried out; Can dual power supply, there is no external power source, can internal electric source be used; Without external switch, by clinical manipulation program, when binding tourniquet, contact microswitch, can operate.
Accompanying drawing explanation

Accompanying drawing 2 is the structural representation of the utility model specific embodiment 2.
Wherein, 1, power pump; 2, simulated blood vessel; 3, electric supply installation; 4, microswitch; 5, inlet; 6, leakage fluid dram; 7, submersible pump; 8, liquid storing bag; 9, reservoir.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings below.
embodiment 1:
As shown in Figure 1, a kind of simulation vein puncture device, is characterized in that, comprise power pump 1, simulated blood vessel 2, electric supply installation 3 and microswitch 4.
Wherein, described simulated blood vessel 2 is connected with power pump 1, forms loop, when power pump 1 works, outside liquid can be pumped in simulated blood vessel 2, and controls to form certain pressure.
Described electric supply installation 3, microswitch 4 are connected with power pump 1.
Described microswitch 4 is for controlling unlatching and the stopping of power pump 1.
Described power pump 1 is provided with inlet 5 and leakage fluid dram 6.
Described inlet 5 and leakage fluid dram 6 are respectively arranged with plug, prevent leakage.
Described electric supply installation 3 can be external power source, also can be internal electric source.
In use, first utilize and tie up the startup that tourniquet touches microswitch 4, power pump 1 is started working, and outside liquid pumps in simulated blood vessel 2, controls to form certain pressure; Simulated blood vessel 2 is in full state; When puncture enters simulated blood vessel 2, due to pressure differential, form blood back phenomenon, blood flows into puncture needle automatically, completes blood sampling work; Unclamp tourniquet, power pump 1 quits work, now distress resolves, also can remain a part of liquid in simulated blood vessel 2, fetch boiling water only, liquid from infusion bottle because high stress is poor, liquid is injected in simulated blood vessel 2, flow to pump with simulated blood vessel and by leakage fluid dram, liquid discharged, complete transfusion work.
embodiment 2:
As shown in Figure 2, be one simulation upper arm vein puncture device, comprise reservoir 9, the liquid storing bag 8 be connected with reservoir 9, submersible pump 7, microswitch 4 and electric supply installation 3.
Described submersible pump 7 is placed in reservoir 9, and connecting analog blood vessel 2, simulated blood vessel 2 and reservoir 9 form loop.
Described reservoir 9 is provided with inlet 5 and leakage fluid dram 6.
After liquid floods submersible pump 7, submersible pump 7 normally can pour into liquid, after submersible pump 7 works, and flow direction simulated blood vessel 2 in reservoir 9.
Described reservoir 9 is that in reservoir 9, liquid can flow to liquid storing bag 8 when liquid height in reservoir 9 is to height with liquid storing bag 8 connecting pipe of reservoir 9.
Carrying out in the venipuncture of simulation upper arm, blood sampling and infusion process, first utilize and tie up the startup that tourniquet touches microswitch 4, submersible pump 7 is started working, after liquid floods submersible pump 7, the liquid of reservoir pumps into simulated blood vessel 2, and simulated blood vessel 2 pressure there will be change, is in full state; When puncture enters simulated blood vessel 2, pressure divides and is depressed into puncture needle, and form blood back phenomenon, blood flows into puncture needle automatically, completes blood sampling work; Unclamp tourniquet, submersible pump 7 quits work, now distress resolves, also can remain a part of liquid in simulated blood vessel 2, operator carries out simulation transfusion operation, only fetches boiling water, liquid because high stress is poor, injects in simulated blood vessel 2 from infusion bottle by liquid, flows in reservoir 9 with simulated blood vessel 2; When liquid reach liquid storing bag 8 connect the mouth of pipe time, flow direction liquid storing bag 8, completes transfusion work.
