Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to the technical fields of intravenous injection and arterial puncture, and specifically refers to a wearable intravenous injection and arterial puncture model. Background Technique
[0002] Both intravenous injection and arterial puncture are the most commonly used operations in clinical practice. In traditional intravenous injection, trainees train with each other on the dorsal veins of their peers. Such a training mode lacks sufficient training opportunities for nursing trainees, and mutual training may cause certain damage to peers. Most traditional arterial punctures are trained and learned directly in clinical practice. When trainees' operation skills are insufficient in the initial stage of learning, it may cause damage to patients and may also result in puncture failure. Although there are some puncture models for existing intravenous injection and arterial puncture, the simulated skin at the puncture site of the mold is easily damaged after being punctured more than a dozen times, resulting in blood leakage from blood vessels, and there is a lack of a training model that can simulate the pulsation of the radial artery. In addition, when performing clinical intravenous injection or arterial puncture, trainees may face patients and their families with various temperaments and personalities, and the training of doctor-patient communication for trainees also needs to be further improved. Traditional intravenous injection and arterial puncture models generally simulate an arm placed on a table, and trainees train for intravenous puncture facing the arm model, which can only train technical skills and cannot train non-technical skills for trainees on how to communicate with various patients.
