Radial artery puncture model with artificial pulse

Abstract

The invention relates to a radial artery puncture model with artificial pulse, and belongs to the technical field of medical appliances. The model comprises a simulated arm model and an artificial blood vessel; the artificial blood vessel is placed in a radial artery conduit in the simulated arm model, and further comprises a pulse generation mechanism, the pulse generation mechanism comprises a piston mechanism and a pulse source motor module; one side of the piston mechanism is provided with an output end, the output end is communicated with one end of the artificial blood vessel; the pulse source motor module is used for driving the piston of the piston mechanism to reciprocate so as to provide pressure for the artificial blood vessel. The model can be used for vividly simulating the pulse of the human body so that the medical worker can improve the puncture training effect using the model, promote the operation proficiency degree to relieve the pain of the patient; the model can be reused without additionally feeding liquid, the parts cost and the training cost are saved, and the operation step is simple.

Description

technical field [0001] The present invention relates to the technical field of medical machinery, in particular to the technical field of medical experiment models, in particular to a radial artery puncture model with simulated pulsation. Background technique [0002] Radial artery puncture is a commonly used operation in clinical practice, and radial artery puncture is convenient and safe. However, due to its thin anatomical structure, especially when the radial artery pulse is weak, the difficulty of puncture increases significantly. Multiple punctures also increase the pain of the patient, and it is more likely that tension will appear further, causing spasm of the radial artery, which will also bring certain benefits to clinical puncture. difficulty. Therefore, medical staff need repeated simulation exercises to master this technology. However, the existing models are not conducive to the practitioners to feel the pulsation feeling or observe the simulation effect of ar...

However, due to its thin anatomical structure, especially when the radial artery pulse is weak, the difficulty of puncture increases significantly, and multiple punctures also increase the pain of the patient, and it is more likely that tension will appear further, causing spasm of the radial artery, which will also bring certain benefits to clinical puncture. difficulty

Therefore, medical staff need repeated simulation exercises to master this technology. However, the existing models are not conducive to the practitioners to feel the pulsation feeling displayed or to observe the due simulation effects such as arterial blood return, or the simulation materials are inconvenient to maintain. Complicated, high cost of practice and other disadvantages
