Description
Technical field
The present invention relates to medical teaching field, particularly relate to a kind of device simulated venipuncture, take a blood sample and infuse.
Background technology
The most existing model is the puncture of simple hand back vein, infusion model；Have the while of for having dorsal venous rete of hand and elbow venipuncture, two functions of transfusion, 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) with hands, then punctures.At present, mechanical type infused-arm (without power supply), electronic type infused-arm (internal electric source), electronic type infused-arm (external power source) it are divided on the market；Infused-arm model on the market, only dorsal venous rete of hand, or containing forearm；Judging that puncture is the most successful, whether lean on is to have blood back phenomenon to produce in the transparent tube of the other end of pin；This blood back phenomenon, at the water do not opened on tube for transfusion only, should not disappear；After unlatching, blood back phenomenon just can disappear；Conventional infused-arm is totally lost after liquid first student, and after needing artificial the interference, second student just can use.Interfere without artificial, when second student operates, the liquid stopped in puncturing pipeline, correctly just cannot judge whether student operates correctly either with or without puncturing.
Summary of the invention
The purpose of the invention is to provide the device of a kind of medical lecture model, it is provided that medical worker or student simulate the puncture of true man's veins of upper extremity, blood sampling, the teaching mode of transfusion operation exercise；Without external switch, by clinical manipulation program, when binding tourniquet, contact microswitch, can operate.
The technical solution adopted in the present invention is, a kind of simulation vein puncture device, it is characterised in that include kinetic pump, simulated blood vessel, electric supply installation and microswitch.
Wherein, described simulated blood vessel is connected with kinetic pump, forms loop, when kinetic pump works, can be pumped in simulated blood vessel by outside liquid, and control to form certain pressure.
Described electric supply installation, microswitch are connected with kinetic pump；Microswitch is for controlling unlatching and the stopping of pump.
It is provided with inlet and leakage fluid dram on described pump, is respectively arranged with plug, prevent leakage.
Described electric supply installation can be external power source, it is also possible to be internal electric source.
The beneficial effects of the present invention is, 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 safety is higher；By clinical vein puncture, blood sampling, transfusion operation step, can truly do simulated exercises；External power source can not be had, it is possible to use internal electric source with dual power supply；Without external switch, by clinical manipulation program, when binding tourniquet, contact microswitch, can operate.

:
As it is shown in figure 1, a kind of simulation vein puncture device, it is characterised in that include kinetic pump 1, simulated blood vessel 2, electric supply installation 3 and microswitch 4.
Wherein, described simulated blood vessel 2 is connected with kinetic pump 1, forms loop, when kinetic pump 1 works, can be pumped in simulated blood vessel 2 by outside liquid, and control to form certain pressure.
Described electric supply installation 3, microswitch 4 are connected with kinetic pump 1.
Described microswitch 4 is for controlling unlatching and the stopping of kinetic pump 1.
Inlet 5 and leakage fluid dram 6 it is provided with on described kinetic pump 1.
It is respectively arranged with plug on described inlet 5 and leakage fluid dram 6, prevents leakage.
Described electric supply installation 3 can be external power source, it is also possible to be internal electric source.
In use, first with tying up tourniquet and touch the startup of microswitch 4, kinetic pump 1 starts working, and outside liquid pumps in simulated blood vessel 2, controls to form certain pressure；Simulated blood vessel 2 is in full state；When puncturing entrance simulated blood vessel 2, due to pressure differential, forming blood back phenomenon, blood automatically flows into puncture needle, completes work of taking a blood sample；Unclamping tourniquet, kinetic pump 1 quits work, now distress resolves, also can remain a part of liquid in simulated blood vessel 2, only open water, liquid is poor because of high stress from infusion bottle, inject liquid in simulated blood vessel 2, flow to pump with simulated blood vessel and by leakage fluid dram, liquid discharged, completing work of infusing.
Embodiment

:
In as shown in Figure 2, simulate upper arm vein puncture device, liquid storing bag 8, immersible pump 7, microswitch 4 and the electric supply installation 3 being connected including reservoir 9 with reservoir 9 for one.
Described immersible pump 7 is placed in reservoir 9, and connects simulated blood vessel 2, and simulated blood vessel 2 and reservoir 9 form loop.
Inlet 5 and leakage fluid dram 6 it is provided with on described reservoir 9.
After liquid floods immersible pump 7, immersible pump 7 can normally pour into liquid, and after immersible pump 7 work, in reservoir 9, liquid flows to simulated blood vessel 2.
Described reservoir 9 is that in reservoir 9, liquid can flow to liquid storing bag 8 when in reservoir 9, liquid height is to the height of reservoir 9 and liquid storing bag 8 connecting tube.
In being simulated upper arm venipuncture, blood sampling and infusion process, first with tying up tourniquet and touch the startup of microswitch 4, immersible pump 7 is started working, after liquid floods immersible 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 puncturing entrance simulated blood vessel 2, pressure dividing potential drop to puncture needle, form blood back phenomenon, blood automatically flows into puncture needle, completes work of taking a blood sample；Unclamping tourniquet, immersible pump 7 quits work, now distress resolves, also can remain a part of liquid in simulated blood vessel 2, operator is simulated transfusion operation, only opens water, liquid is poor because of high stress from infusion bottle, injects liquid in simulated blood vessel 2, flows in reservoir 9 with simulated blood vessel 2；When liquid reach liquid storing bag 8 connect the mouth of pipe time, liquid flows to liquid storing bag 8, complete infuse work.
