Problems solved by technology

[0004] In medicine, the health status of the human body can be judged from the abnormal sweating, but so far, there is no technology to simulate the sweating of the human body, especially in the education industry, teachers can only describe the human body through words during the teaching process Abnormal perspiration, but can not simulate the normal perspiration and abnormal perspiration of the human body for students

Abstract

The invention provides an artificial skin for simulating perspiration, which includes a water-permeable layer and a temperature-sensitive polyurethane hydrogel layer. The beneficial effects of the present invention are: the polyurethane hydrogel layer and the water-permeable layer disclosed by the present invention have precise temperature-sensitive performance, which ensures that the artificial skin can simulate the perspiration of the human body at different temperatures, and provides more intuitive explanations for medical teaching, which is convenient Students understand normal and abnormal perspiration and can reuse it as many times as needed.

Description

technical field [0001] The invention relates to the field of medical education, in particular to an artificial skin for simulating perspiration. Background technique [0002] Perspiration is a physiological regulation function of the human body under the action of external thermal stress. When the heat production of human metabolism is higher than the heat dissipation to the environment, the human body begins to perspire, and achieves thermal balance through perspiration. [0003] Sweating is a normal physiological reaction, which can be divided into warm sweating, exercise sweating, mental sweating and gustatory sweating. Excessive consumption of qi, damage to body fluid and loss of heart and blood, a large amount of yang qi leaks out, it is easy to make people tired and weak, flustered and short of breath, and different parts of the body sweat, corresponding to different health problems of the body, such as: sweating on the head Abnormal TCM thinks that the stomach fire ...
