Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a temperature sensing detection device. Background Art

[0002] Skin temperature perception is one of the important indicators of normal sensory function. Existing temperature perception detection methods mainly include the following:

[0003] (1) Hot water immersion method: The test subject immerses his hands or feet in water of different temperatures. The test subject senses the cold and hot water through the skin and feeds back the results of the skin's cold and hot sensations to the test subject. When testing by water temperature, the water temperature cannot be accurately controlled, which can easily affect the accuracy of skin temperature detection.

[0004] (2) Hot plate method: The tester places a hot plate on the subject's skin and gradually heats it up. The subject senses the temperature of the hot plate and feeds back the results of the hot and cold sensations to the tester. During the test, the temperature of the hot plate needs to be raised or lowered during the test because the temperature sensation of the subject's skin is different at different locations. The temperature rise or fall is difficult to control during the test, and it is not convenient to detect the subject's skin temperature sensation.

[0005] (3) Hot air blowing method: Use a hair dryer to blow hot air toward the subject's skin, and gradually increase the temperature during the blowing process. The subject's skin senses the temperature of the hot air, and the results of the skin's hot and cold sensations are fed back to the subject. This method uses a fan to blow hot air toward the subject's skin, so that the hot air cannot be concentrated during the flow, making it difficult to detect the skin's temperature sensation.

[0006] Although the above methods are all capable of detecting temperature perception, the results of each individual's temperature perception detection are different, so that the tester needs to quickly adjust the temperature of the detection device when detecting temperature perception. The temperature range of skin temperature perception detection is a minimum temperature of 5°C-10°C and a maximum temperature of 40°C-50°C. However, when the above methods are used for testing, the temperature adjustment process is relatively cumbersome, and the accuracy of the test temperature change control and the accuracy of the test skin range control are not high. At the same time, the test results cannot be objectively quantified, resulting in large errors in the test results, which is not convenient for the tester to make a normal diagnosis of the test subject's skin temperature perception.
