Description

Technical Field

[0001] The utility model relates to the technical field of tactile perception testers, in particular to a tactile perception tester. Background Art

[0002] In neurology, when doctors want to determine the patient's nerve damage, they need to check the nerves or root nerves in a certain area of ​​the patient. The pupil photosensitivity reflex that reflects vital signs and the identification of the nature of surface masses require light transmission tests, percussion, and scratching. In order to clarify the patient's nerve reflex function, the feeling produced by the skin's tactile receptors contacting mechanical stimulation is called touch. There are touch points scattered on the skin surface. The sizes of the touch points are different and the distribution is irregular. Generally, the fingertips have the most touch points, followed by the head, and the back and calves have the least. Therefore, the fingertips have the most sensitive touch, while the calves and back have a dull touch. If you touch the skin surface lightly with fine hair, the touch can only be caused when certain special points are touched. The current common tester is a needle-shaped tactile device, which examines the patient's sense of touch by acupuncture of various points on the patient's skin.

[0003] When doctors need to test the tactile sensation of the patient's skin surface, they often need to use a tactile perception tester. Although the existing tactile perception tester technology is simple to use and has low production cost, the existing tactile perception tester often requires doctors to manually check when used for diagnosis and treatment. Therefore, the detection may not be accurate enough due to the different force used each time. At the same time, it is not convenient to accurately adjust the force during the test, which may make it inconvenient for doctors to accurately treat patients' diseases.

[0004] Therefore, those skilled in the art provide a tactile perception tester to solve the problems raised in the above background technology. Utility Model Content
