Abstract
The utility model discloses a kind of pain threshold surveying instrument, it is provided with injector head in the front end of body, and tail end is connected with water tank by catheter, and the rearward end of body is provided with perpendicular handle; The positioning sleeve of sidewall hollow out is installed on front side of injector head; Handle inner hollow, intracavity is installed on controller, and outside is provided with the trigger-type adjusting knob and display screen that are connected with controller; Catheter between body and water tank is provided with electric heating device, temperature sensor, pressure regulating pump and flow sensor; Electric heating device, temperature sensor, pressure regulating pump and flow sensor all pass through connection with controller.Because it adopts the stamping press of current to produce stimulation to patient, more traditional detection contact is compared, and it calculates the threshold of pain according to flow velocity, advantageously in the accurate measured value of acquisition, and can not damage patient in measuring process; It has both the function that the temperature threshold of pain is measured simultaneously.Its structure is simple, easy to operate, quick, safety, measures accurately, has significant practicality.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly relates to a kind of pain threshold surveying instrument.
Background technology
Clinically, usually adopt threshold of pain pin to measure the threshold of pain of patient, this mode is comparatively simple and easy, but only judges the size of the threshold of pain with the feel of doctor and experience in operating process, and the error of existence is comparatively large, measured value inaccuracy.In addition, also have in scheme and adopt the mode of hydraulic pressure, air pressure to drive contact, calculating is carried out to obtain Pain-threshold finally by pressure, its comparatively manual detection accuracy tool improve, but the pressure change step values needed due to contact in the detection of the threshold of pain is less, this small change is difficult to measure in hydraulic pressure, air pressure, therefore measurement result also exists larger error, can not reach desirable clinical effectiveness; And misoperation also may damage patient.
Utility model content
For overcoming above-mentioned technical problem, it is simple that this utility model provides a kind of structure, easy and safe to operate, measures pain threshold surveying instrument accurately.
For realizing above-mentioned technical purpose, this utility model adopts following scheme: a kind of pain threshold surveying instrument, comprises a body, and the front end of described body is provided with injector head, and tail end is connected with water tank by catheter, and the rearward end of body is provided with perpendicular handle; The positioning sleeve of sidewall hollow out is installed on front side of described injector head; Described handle inner hollow, intracavity is installed on controller, and outside is provided with the trigger-type adjusting knob and display screen that are connected with controller; Catheter between described body and water tank is provided with electric heating device, temperature sensor, pressure regulating pump and flow sensor; Described electric heating device, temperature sensor, pressure regulating pump and flow sensor all pass through connection with controller.
Operation principle of the present utility model is: positioning sleeve is supported the body surface place at patient position to be detected, water pumps in body by booster pump, patient body-surface is sprayed on through injector head, because current at a high speed have larger impulsive force, and stimulation is produced to patient, progressively hydraulic pressure is increased by trigger-type adjusting knob, due in testing process positioning sleeve ensure that injector head and patient's relative spacing constant, when patient feels pain, the data that controller can record according to flow sensor calculate the surge suffered by patient, and then record Pain-threshold; Make pressure regulating pump steady operation, progressively increase water temperature by trigger-type adjusting knob, as patient feels pain, the data that can record according to temperature sensor calculate the temperature pain threshold of patient.
This utility model has following beneficial effect: because it adopts the stamping press of current to produce stimulation to patient, more traditional detection contact is compared, it calculates the threshold of pain according to flow velocity, advantageously in the accurate measured value of acquisition, and can not damage patient in measuring process; It has both the function that the temperature threshold of pain is measured simultaneously.Its structure is simple, easy to operate, quick, safety, measures accurately, has significant practicality.
