Abstract
The invention discloses a kind of demonstrator for vein paracentesis, which includes a simulating demonstrator, a simulative vessel, and a vessel cork, a connector for the simulative vessel and the perfusion tube and the perfusing device. The board is made up of silicon rubber with the same color to the skin; there has four hollow cavities with different colors in the centre of the board. Four baby blue simulative vessels with different diameters are set in the hollow cavities. There have eight corks set at two ends of the simulative vessels. One end of the connector is connected to the simulative vessel; another end is connected to the pin of the perfusing device. The perfusing device is made up of a normal perfusing bag and a perfusing device without pin.
Description
Technical field
The present invention relates to a kind of venipuncture teaching machine, specifically, relate to a kind of venipuncture teaching machine that is used for medical teaching.
Background technology
The venipuncture technology is the basic operating technical ability that numerous medical workers, particularly medical practitioner, nurse must grasp.Hospital, medical university, protect unit such as school when carrying out the venipuncture teaching, very inconvenient, still there is not a kind of both safety, simple, practical, cheap again educational aid and method, normally puncture mutually between the medical personnel, so both dangerous, can not be used for repeatable operation again.More existing emulation arm model teaching aids, though can play certain teaching function, price is very expensive, is not suitable for very much the national conditions of China.
Summary of the invention
The purpose of this invention is to provide a kind of both simple and practical, the low-cost again venipuncture teaching machine that is used for medical teaching.
Principle of the present invention is to utilize the silicon rubber apery skin close with skin color, utilize silicone rubber tube apery blood vessel azury, utilize the infusion set certain altitude to provide certain pressure similar to vein pressure to simulated blood vessel, integrate just provide one to the clinical vein similar environment that punctures.
Concrete technology of the present invention realizes by following scheme: use has the fine flexible silicon rubber close with skin color and makes a rectangle emulation demonstrator, the silicone rubber tube azury that has four thicknesses not wait in the demonstrator, and does not wait the depth position of silicone rubber tube azury in the emulation demonstrator yet, the effect that causes the blood vessel depth not wait, infusion set is made up of common transfusion bag and the transfusion device that removes syringe needle, in the common transfusion bag red ink is housed, by transfusion device ink is imported in the simulated blood vessel, end at transfusion device has a simulated blood vessel and transfusion device tube connector, it can be connected the woven hose end with simulated blood vessel, the other end of simulated blood vessel has the blood vessel stopper of being made by medical plastic, is used for stopping up the other end of simulated blood vessel.When the exercise venipuncture procedure, if when wanting to practise the puncture than thin vein, the stopper of simulated blood vessel one end that just will be thinner is pulled up, the transfusion device that will have connector simultaneously connects, at this moment, infusion regulator is opened, and red liquid injects in the simulated blood vessel, and medical personnel can practise, since simulated blood vessel be by elasticity preferably silicon rubber make, in puncture needle enters simulated blood vessel, a stronger sense that falls through is arranged, visible at once return " blood ".
In sum, advantage of the present invention is: simple and practical, and low price.
Description of drawings
Below in conjunction with accompanying drawing to further detailed explanation of the present invention.
Figure is a structural representation of the present invention.
Transfusion device 8. transfusion devices that 1. emulation demonstrators, 2. simulated blood vessel 3. blood vessel stoppers, 4. simulated blood vessels and transfusion device tube connector 5. infusion regulators 6. common transfusion bags 7. remove syringe needle among the figure meet the syringe needle place
Embodiment
As seen from the figure, the present invention includes emulation demonstrator 1, simulated blood vessel 2, blood vessel stopper 3, simulated blood vessel and transfusion device tube connector 4 and infusion set.Emulation demonstrator 1 is to be made of the rectangular silicon rubber close with skin color, and there is the open columniform cavity of placement simulated blood vessel 2 usefulness that four depths do not wait in its central authorities.Article four, the simulated blood vessel 2 that the thickness that is made of silicon rubber azury does not wait is placed in the cavity.Blood vessel stopper 3 is round stoppers of being made by medical plastic, totally eight, places the two ends of every simulated blood vessel 2 respectively.Simulated blood vessel and transfusion device tube connector 4 are to be made by medical plastic, and the one end is connected with simulated blood vessel 2, and the other end is connected with the syringe needle place 8 that connects of transfusion device.Utilize the infusion set certain altitude certain pressure similar to vein pressure to be provided for simulated blood vessel 2, integrate just provide one to the clinical vein similar environment that punctures.Emulation demonstrator 1 interior four silicone rubber tube thicknesses azury do not wait, does not wait depth position yet, the effect that causes the blood vessel depth not wait, infusion set is made up of common transfusion bag 6 and the transfusion device 7 that removes syringe needle, in the common transfusion bag 6 red ink is housed, by transfusion device 7 ink is imported in the simulated blood vessel 2, end at transfusion device 7 has a simulated blood vessel and transfusion device tube connector 4, it can be connected the woven hose end with simulated blood vessel 2, the other end of simulated blood vessel 2 has the blood vessel stopper of being made by medical plastic 3, is used for stopping up the other end of simulated blood vessel 2.When the exercise venipuncture procedure, if when wanting to practise the puncture than thin vein, the stopper 3 of simulated blood vessel 2 one ends that just will be thinner is pulled up, the transfusion device 7 that will have connector 4 simultaneously connects, at this moment, infusion regulator 5 is opened, and red liquid injects in the simulated blood vessel 2, and medical personnel can practise, since simulated blood vessel 2 be by elasticity preferably silicon rubber make, in puncture needle enters simulated blood vessel 2, a stronger sense that falls through is arranged, visible at once return " blood ".
Claims (4)
1. a venipuncture teaching machine comprises emulation demonstrator, simulated blood vessel, blood vessel stopper, simulated blood vessel and transfusion device tube connector and infusion set.It is characterized in that the emulation demonstrator is to be made of the rectangular silicon rubber close with skin color, there is placement simulated blood vessel that four depths do not wait in its central authorities with open columniform cavity.Article four, the simulated blood vessel that the thickness that is made of silicon rubber azury does not wait is placed in the cavity.
2. a kind of venipuncture teaching machine according to claim 1 is characterized in that: described blood vessel stopper is the round stopper of being made by medical plastic, totally eight, places the two ends of every simulated blood vessel respectively.
