Mechanical pain sensitivity measurement instrument

Abstract

The invention discloses a mechanical pain sensitivity measurement instrument, which comprises a shell, wherein a rotary handle, which is capable of rotating in a circumferential direction of the shell, is arranged on the tail of the shell; a rotary tray, which is capable of synchronously rotating along with the rotary handle, is arranged in the shell; the side, facing the front end of the shell, of the rotary tray is provided with a plurality of base inserting holes in the circumferential direction; a measurement wire fixing base is inserted in each base inserting hole, and a measurement wire, which is used for detecting mechanical pain, is arranged at the front end of each measurement wire fixing base; strip-shaped holes are formed in the shell in a length direction; and a clamping piece, which is capable of clamping the measurement wire fixing bases and drawing the measurement wire fixing bases out of the base inserting holes, is additionally arranged on the shell. The mechanical pain sensitivity measurement instrument provided by the invention is mainly used for assessing skin mechanical pain tests; as a non-injury tool for assessing a skin mechanical pain degree, the measurement instrument, when applied to pain tests on a patient, can be used for testing a pain threshold and a pain range of the patient relatively precisely, and an accurate and practical effect can be achieved in a using process.

Description

technical field [0001] The invention belongs to the field of medical appliances, and in particular relates to a mechanical pain sensitivity measuring instrument. Background technique [0002] As we all know, pain is a complex experience and experience, including three main components: sensory identification, emotional motivation and cognitive evaluation. At present, it is believed that when pain intensifies or the body is attacked by inflammation or various injuries, pain no longer plays a protective role, and gradually develops into chronic pathological pain, which can not only cause sensory dysfunction (spontaneous pain, hyperalgesia and allodynia), It also affects many advanced brain functions through the ascending conduction pathway, such as: emotion, cognition, memory, etc., resulting in many pain-related cognitive disorders and mental diseases, such as: anxiety, depression, forgetfulness, insomnia, cognitive impairment Wait. Chronic pain is a functional neurological ...

Problems solved by technology

However, there is currently a lack of simple and easy pain testing equipment in scientific research. In clinical work, the pain testing of patients can only rely on scales and the subjective judgment of patients themselves. There is no objective and effective assessment method and device.
