Radial artery puncture model with artificial pulse

Abstract

The invention relates to a radial artery puncture model with simulated pulsation, belonging to the technical field of medical devices. The model includes a simulated arm model, a simulated blood vessel, the simulated blood vessel is placed in the radial artery channel in the simulated arm model, and a pulsation generating mechanism, which includes a piston mechanism and a pulsation source motor module; a part of the piston mechanism The side has an output end, and the output end communicates with one end of the simulated blood vessel; the pulse source motor module drives the piston of the piston mechanism to reciprocate, so as to provide pressure to the simulated blood vessel. The model can realistically simulate the pulse of the human body, which is convenient for medical staff to use the model to improve the effect of puncture practice, improve operational proficiency, and reduce the pain of patients, and the model can be used repeatedly without additional fluid replacement, saving parts costs and practice costs. The steps are 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
