A pressure stimulation test device, system and method

Abstract

The invention discloses a pressure stimulation testing device, system and method. The system mainly comprises a pressure stimulation testing device, a PC control system, a PLC and a stepper motor drive; the pressure stimulation testing device comprises a force applying component and a force measuring component arranged with the force applying component coaxially. The control system controls the pressure stimulation testing device automatically, the pressure can be controlled to apply accurately, and feedback regulation and secondary compensation are performed according to pressure measurement signals through actual feedback; the testing pressure result of the pressure stimulation test is guaranteed being accurate and actual, the actual and accurate test results can be provided, and the test requirements are met.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a pressure stimulation test device, system and method. Background technique [0002] In the fields of clinical medicine and basic medicine, it is often necessary to apply pressure to the human or animal body in order to achieve the pain sensation induced by pressure stimulation in the series of scientific research on pain such as the manufacture of experimental models, pain degree assessment, pain-related expressions, behaviors, and changes in physiological parameters. Traditional mechanical noxious pressure stimulation-induced pain equipment cannot meet the requirements of remote control and precise control. It usually needs to be operated by the experimenter, and in the process of pressure stimulation-induced pain, there are poor controllability of pressure value and time variables. Problems such as low accuracy and incomplete data feedback affect the accuracy of pain...

AI Technical Summary

Problems solved by technology

Traditional mechanical noxious pressure stimulation-induced pain equipment cannot meet the requirements of remote control and precise control. It usually needs to be operated by the experimenter, and in the process of pressure stimulation-induced pain, there are poor controllability of pressure value and time variables. Problems such as low accuracy and incomplete data feedback affect the accuracy of pain scientific research and clinical evaluation of pain

[0003] Therefore, the pressure value applied by the pressure stimulus in the prior art to induce pain has low accuracy and poor adjustability, the duration of pain stimulation and the interval between adjacent stimuli cannot be accurately controlled, and there is no pressure feedback and readjustment Function, poor safety performance during the experiment

At the same time, the on-site operation of the experimenters has a psychological impact on the subjects or experimental animals to a certain extent. It is obvious that the pressure stimulus-induced pain of the existing technology cannot achieve the expected goal.
