Abstract

The utility model discloses an arterial puncture exercise device which mainly consists of a puncture module, a liquid storage bag, and a pedestal. A simulated blood vessel is put in the puncture module, and two ends of the simulated blood vessel are respectively provided with a connector which is in snap-fit connection with a connecting tube of the pedestal. The liquid storage bag is a bag which is made of elastic rubber materials and can generate deformation. Two connecting tubes stretch out from one end of the bag, and the interiors of the two connecting tubes are respectively provided with a non-return valve. The pedestal is provided with a switch which is used for controlling liquid in the liquid storage bag to flow out to the puncture module. The puncture module, the liquid storage bag and the pedestal are connected with each other via the connecting tubes. The liquid storage bag generates continuous deformation, so as to simulate heartbeat of a human body and enable the simulated blood vessel inside the puncture module to generate an effect of arterial pulse. Therefore, students can simulate a few of scenes by themselves to carry out one-to-one exercises, and can master each skill of arterial puncture in time.

Description

The artery puncture practice device

Technical field

The utility model belongs to a kind of medical teaching teaching aid, relates in particular to a kind of device for artery puncture practice.

Background technology

Artery refers to that the blood will flowed out from heart is transported to the blood vessel of parts of body.Serious shock needs the patient of first aid, and situation has no improvement after the vein quick blood transfusion, must improve the coronary perfusion amount and increase effective blood volume through artery.The purpose of arteriopuncture operation is to get blood to do arterial blood gas analysis, and microbe growth is made in blood sampling.Artery is usually unlike peripheral vein, shows shallowly, visible, and position is darker usually, and with beating, during puncture, blood vessel easily slides, and makes puncture needle can not lunge easily blood vessel.Clinically, normally first with the hand palpation to the strength of arteriopalmus, then press blood vessel with forefinger and middle finger, two, thrust puncture needle between pointing.Such gimmick, the old nurse operation be skilled in technique get up accurately, rapidly, but for student or the new hand of just registration, or difficult.Exercise just seems essential.

The utility model content

The utility model provides a kind of artery puncture practice device, and 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 utility model has adopted such technical scheme: mainly piercing module, reservoir, base, consist of;

Described piercing module inside is built-in with simulated blood vessel, and the 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 an end of capsule stretches out two connecting pipes, on pipe, respectively is built-in with a retaining valve;

A switch is arranged on described base, 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 beneficial effects of the utility model are, it is by making reservoir produce continuous deformation, and the simulation human heart is beated, and make simulated blood vessel in piercing module produce the effect of arteriopalmus, and the student can independently simulate some scenes, carries out man-to-man training.Can grasp in time every arteriopuncture technical ability.

Embodiment

Below in conjunction with accompanying drawing, be described further.

As shown in Figure 1, the artery puncture practice device mainly is comprised of reservoir 1, base 4, piercing module 7, by connecting pipe, connects between reservoir 1, base 4 piercing module 7 threes.

Piercing module 7, inside are 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 the pipeline one-way circulation, when the simulation human heart shrank, liquid was clamp-oned in the one-way circulation pipeline by a side retaining valve; In the time of simulation human heart diastole, liquid returns in reservoir 1 by the 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 the utility model preferred embodiment, not the utility model done to any pro forma restriction.Every foundation technical spirit of the present utility model is to any simple modification made for any of the above embodiments, and equivalent variations and modification, still belong in the scope of technical solutions of the utility model.

Claims (2)

1. artery puncture practice device is characterized in that: mainly by piercing module, reservoir, base, formed,
