Further, in a preferred embodiment of the present invention, the pulse generating device is a balloon disposed at one end of the arterial tube and disposed outside the foam block.

One end of the arterial tube is provided with a compressible elastic balloon similar to that on a sphygmomanometer, the balloon is squeezed to generate human body simulated pulse in the arterial tube, the pulse can be transmitted to simulated skin through the elastic supporting block, and a trainer can feel the pulse through touch to perform puncture practice.

Further, in the preferred embodiment of the present invention, the pulse generator is an electronic sensor using the principle of "electromagnet", and the electronic sensor is disposed in the arterial tube where the pulse is to be set.

When the examination or the independent operation is needed, the pulse generating device can adopt an electronic sensor based on the electromagnet principle, the sensor can simulate the artery pulse with the frequency consistent with the real patient, and the auxiliary operation of others is not needed.

Further, in the preferred embodiment of the present invention, the supporting block is made of foam.

The foam material has low cost, is easy to obtain and process pipelines, and has certain elasticity so as to effectively transmit pulse.

Further, in the preferred embodiment of the present invention, the support block is a cube of 10cm × 10cm × 10 cm.

Further, in the preferred embodiment of the present invention, the artery and vein are pressure pulse belts.

The tourniquet is easy to obtain, has elasticity, and can better simulate the blood vessel of a human body.

The utility model discloses following beneficial effect has:

the utility model provides a simple and easy vascular puncture puts a tub model, satisfy medical student's daily artery, venipuncture, draw blood, put the pipe, various operations such as injection, the device is through setting up the human muscle of elasticity supporting shoe simulation, a be used for supporting arterial canal and venous canal, elastic supporting shoe can also effectively conduct the artery pulse, be used for simulating human pulse through setting up pulse generating device on the arterial canal, satisfy the arteriopuncture requirement, the emulation skin has still been laid to the elasticity supporting shoe upper surface, reinforcing model training effect, the device overall structure is simple, the material low price, the preparation is convenient, be convenient for relevant operations such as the medical student's exercise puncture of being convenient for.

Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

Example 1

Referring to fig. 1, the vascular puncture catheterization model comprises a base 1 and an elastic supporting block 2 detachably arranged on the base 1, wherein the elastic supporting block 2 can be replaced after being used for a certain time, two pipelines are arranged in the elastic supporting block 2, an arterial tube 3 and a venous tube 4 are respectively arranged in the two pipelines, red liquid is injected into the arterial tube 3, blue liquid is injected into the venous tube 4, a balloon 31 is arranged at the end part of the arterial tube 3, a simulated skin layer 5 is further laid on the supporting block, the supporting block is a cube of 10cm × 10cm × 10cm, the supporting block is made of foam, and the arterial tube 3 and the venous tube 4 are made of tourniquets.

In this embodiment, venous duct 4 and arterial duct 3 keep away from emulation skin layer 5, bury in elastic support block 2 inside promptly, when needs practise puncture or put the pipe operation, according to the operation requirement, at first at the model top layer shop towel, only expose the position that needs the puncture, shop towel need with arterial duct 3 and venous duct 4 both ends cover, avoid the operator to see the position of arterial duct 3 and venous duct 4, then extrude the gasbag simulation human pulse according to certain frequency by another operator, the puncture operator is with hand response pulse and puncture or put the pipe exercise.

Example 2

Referring to fig. 2, the difference between the embodiment 2 and the embodiment 1 is that the artery 3 and the vein 4 are arranged on the surface of the elastic support block 2, the simulated skin layer 5 is laid on the artery 3 and the vein 4, because red or blue liquid is injected into the artery 3 and the vein 4, the artery and the vein can be directly observed through the simulated skin layer 5, so as to simulate the blood vessel at the shallow position of the human body surface layer, the difference between the embodiment 2 and the embodiment 1 is that an electronic sensor 32 adopting the 'electromagnet' principle is arranged in the artery 3 for generating pulse simulating human body pulse with certain frequency, compared with the manual squeezing air bag in the embodiment 1, when the electronic sensor 32 is used for simulating the human pulse, the auxiliary of other operators is not needed, the puncture practice can be independently completed, and the method is suitable for the condition that the examination and the like need to be operated independently, before use, a drape is laid as in example 1, and only the portion to be punctured is exposed, and the position of the arterial tube 3 and the venous tube 4 is observed and the pulse is sensed to perform a corresponding transfusion or other exercises.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
