Abstract
Provided is an arterial puncture practice device which is mainly composed of a puncture module, a liquid storage capsule and a pedestal. The internal part of the puncture module is internally provided with a simulated blood vessel. The two ends of the simulated blood vessel are provided with connectors which are connected with connecting pipes of the pedestal in a buckling way. The liquid storage capsule is an elastic deformable capsule made of rubber material. Two connecting pipes stretch out of one end of the capsule, and the pipes are internally provided with a non-return valve respectively. The pedestal is provided with a switch which is used for managing liquid in the liquid storage capsule to flow out of the liquid storage capsule into the puncture module via the connecting pipes. The puncture module, the liquid storage capsule and the pedestal are connected via the connecting pipes. The liquid storage capsule is enabled to continuously deform to simulate heartbeat of a human body so that the arterial pulse effect is generated by the simulated blood vessel in the puncture module, and certain scenes can be simulated by students independently for one-to-one training. Various arterial puncture skills can be timely mastered.
Description
Technical field
The invention belongs to a kind of medical teaching teaching aid, relate in particular to a kind of device for artery puncture practice.
Background technology
Artery refers to the blood vessel that the blood flowing out from heart is transported to parts of body.Serious shock needs the patient of first aid, and after vein quick blood transfusion, situation has no improvement, must improve coronary perfusion amount and increase effective blood volume through artery.The object of arteriopuncture operation is to get blood to do arterial blood gas analysis, and microbe growth is made in blood sampling.Artery is conventionally unlike peripheral vein, shows shallow, as seen, and position is darker conventionally, and with beating, when puncture, blood vessel easily slides, and makes puncture needle can not lunge easily blood vessel.Clinically, normally first with hand palpation to the strength of arteriopalmus, then press blood vessel with forefinger and middle finger, between two fingers, thrust puncture needle.Such gimmick, the old nurse operation being skilled in technique gets up accurately, rapidly, but for student or the new hand of just registration, still suitable difficulty.Exercise just seems essential.
Summary of the invention
The invention provides a kind of artery puncture practice device, it is simple in structure, practical, can both have been simulated by two people the effect of human heart contraction and diastole, the exercise of can puncturing again.
To achieve these goals, the present invention has adopted such technical scheme: be mainly made up of piercing module, reservoir, base;
Described piercing module inside is built-in with simulated blood vessel, and simulated blood vessel two ends have the connecting pipe of connector and base to be fastened and connected;
Described reservoir is one to have the capsule of the produced deformation that flexible elastomeric material makes, and two connecting pipes are stretched out in one end of capsule, are respectively built-in with a retaining valve on pipe;
On described base, there is a switch, be used for managing liquid flowing out in piercing module by connecting pipe in reservoir;
Between described piercing module, reservoir, base, connect by connecting pipe;
On wherein said base, also have two connecting holes, be used for connecting the connecting pipe of reservoir.
The invention has the beneficial effects as follows, it is by making reservoir produce continuous deformation, and simulation human heart is beated, and makes the effect of the simulated blood vessel generation arteriopalmus in piercing module, and student can independently simulate some scenes, carries out man-to-man training.Can grasp in time every arteriopuncture technical ability.

Embodiment
Be described further below in conjunction with accompanying drawing.
As shown in Figure 1, artery puncture practice device is mainly made up of reservoir 1, base 4, piercing module 7, between reservoir 1, base 4 piercing module 7 threes, connects by connecting pipe.
Piercing module 7, inside is built-in with simulated blood vessel 9, and there is connector 8 at simulated blood vessel 9 two ends; Simulated blood vessel 9 can carry out the puncture procedure of artery.
Reservoir 1 is can push and revertible elastic sack body, and two connecting pipes 3 stretch out outside capsule, and every connecting pipe 3 is built-in with a retaining valve, is used for controlling the direction of liquid flow.
Between described piercing module 7, liquid capsule 1, base 4, connect by connecting pipe;
When a student exerts pressure and relief pressure to reservoir 1, simulate contraction and the diastole of human heart, now open switch 5, the liquid in reservoir 1 just can be along pipeline one-way circulation, in the time that simulation human heart shrinks, liquid is clamp-oned in one-way circulation pipeline by a side retaining valve; In the time of simulation human heart diastole, liquid returns in reservoir 1 by opposite side retaining valve, and continuous moving in circles like this makes simulated blood vessel 9 in piercing module 7 produce the effect of similar arteriopalmus.
So just, can carry out man-to-man teaching and exercise, improve student's learning efficiency.
The above, be only preferred embodiment of the present invention, not the present invention done to any pro forma restriction.Every foundation technical spirit of the present invention is to any simple modification made for any of the above embodiments, and equivalent variations and modification, still belong in the scope of technical solution of the present invention.
