Embodiment Construction

[0017] Further description will be made below in conjunction with the accompanying drawings.

[0018] Such as figure 1 As shown, the arterial puncture training device is mainly composed of a liquid storage bag 1, a base 4, and a puncture module 7, and the liquid storage bag 1, the base 4, and the puncture module 7 are connected by a connecting tube.

[0019] The puncture module 7 has a built-in simulated blood vessel 9 with connectors 8 at both ends of the simulated blood vessel 9; the simulated blood vessel 9 can perform arterial puncture operations.

[0020] The liquid storage bag 1 is an elastic bag body that can be squeezed and restored to its original shape. Two connecting pipes 3 extend out of the bag, and each connecting pipe 3 has a built-in one-way valve for controlling the direction of liquid flow.

[0021] The puncture module 7, the liquid bag 1, and the base 4 are connected through a connecting tube;

[0022] When a student applies pressure to the liquid stor...

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 [0001] The invention belongs to a teaching aid for medical teaching, in particular to a device for arterial puncture practice. Background technique [0002] Arteries are blood vessels that carry blood from the heart to various parts of the body. For patients in severe shock who need first aid, the situation has not improved after rapid intravenous blood transfusion, and the coronary artery perfusion must be increased and the effective blood volume increased through the artery. The purpose of the arterial puncture procedure is to draw blood for arterial blood gas analysis and for bacterial culture. Arteries are usually not superficial and visible like peripheral veins, but are usually deep and accompanied by pulsation. When punctured, the blood vessels tend to slide, making it difficult for the puncture needle to penetrate the blood vessels easily. In clinical practice, the strongest arterial pulse is usually palpated by hand first, then the index finger and...
