Abstract
The utility model provides a medical pain stimulation device. The medical pain stimulation device comprises a stepping motor, a screw, a sliding rail, a sliding platform, an elastic sheet, a contact rod, a force measuring platform and a base. The stepping motor and the guiding rail are fixedly connected with the base. One end of the screw is connected with the stepping motor and the other end of the screw is connected with sliding platform in a threaded manner. Two ends of the sliding platform are arranged on the sliding rail. The elastic sheet is fixed below the sliding platform. The lower part of the elastic sheet is connected with the contact rod. The screw is driven to rotate by the rotation of the stepping motor. The sliding platform is pushed by the screw to slide on the sliding rail. The force measuring platform is disposed below the contact rod and is used for measuring pressure from the contact rod exerted on an object to be stimulated. A patient puts a finger on the force measuring platform. The pressure stimulation is exerted on the finger from the above elastic copper sheet. The pressure is exerted on the force measuring platform. The pressure is measured via strain gauges distributed above the force measuring platform and is displayed in a real-time manner by the force measuring platform. The medical pain stimulation device can be used for the study of the painful feeling and the evaluation of analgesic effects and auxiliary diagnosis and treatment on the patient from the medical staff.

A kind of medical pain stimulation instrument, it comprises motor, screw rod, slide rail, slide unit, flexure strip, contact lever, ergograph and base; Motor, slide rail all are fixedly connected with base, and described screw rod one end is connected with motor, and the other end is threaded with slide unit, and the two ends of slide unit are arranged on slide rail, and the slide unit below is fixed with flexure strip, and the flexure strip below connects contact lever; Rotate and drive bolt rotary by motor, screw rod promotes slide unit and slides on slide rail, and ergograph is positioned at the contact lever below, for measuring contact lever, acts on the pressure stimulated on object.
Further optimize, porose in the middle of described slide unit, be carved with the screw thread for being connected with the screw rod coupling in hole.
Further optimize, institute's flexure strip is to bend to the copper sheet of setting radian.
Further optimize, described contact lever is the copper bar welded with described copper sheet.
Further optimize, be distributed with the strain-ga(u)ge transducer for the size of gaging pressure on ergograph.
Further optimize, also comprise testing circuit, amplifying circuit, A/D converter, control unit and display unit, testing circuit is detected the signal of telecommunication of strain-ga(u)ge transducer, amplifying circuit is amplified the signal detected, signal after amplification is changed output digit signals to control unit through A/D converter again, and control unit calculates weight signal and exports to display unit and shows in real time.
Further optimize, described control unit also is connected with the drive circuit of motor, for the rotation of control step motor.
Compared with prior art, the utlity model has following advantage and technique effect:
This utility model is simple in structure, easy to use.Rotate and drive bolt rotary by motor, promote slide unit and slide, the slide unit below is the good copper sheet of elasticity fixedly, and copper sheet is the copper sheet that bends to certain radian, and the copper bar has been welded in the copper sheet below, and the copper bar is pressed finger and produced Pressure stimulation pain.Patient's finger is placed on ergograph, is subject to the Pressure stimulation of the elastic copper sheet of top, and ergograph is under pressure, and the testing circuit that leads to the foil gauge composition distributed on it carrys out the size of gaging pressure.The signal of described strain measurement amplifies through signal amplification circuit, enters the AD modular converter, converts digital signal to, and controller controls according to the size of this signal the size that display module shows power.This utility model can be used for pain perception research, analgesic effect evaluation, medical personnel auxiliary diagnosis and the treatment to pain disease patient.
The accompanying drawing explanation
the electric component part fundamental diagram that Fig. 1 is medical pain stimulation instrument;
fig. 2 is medical pain stimulation instrument frame for movement schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing, enforcement of the present utility model is described further, but enforcement of the present utility model and protection are not limited to this.
Shown in figure 1 and Fig. 2, a kind of medical pain stimulation instrument, comprise control unit, AD converter, display unit, motor-drive circuit, motor, testing circuit, signal amplification circuit.
This example measure portion is to utilize LOAD CELLS detected pressures signal, obtain the faint signal of telecommunication (voltage signal), after then treated circuit (as the filtering testing circuit, differential amplifier circuit) is processed, send A/D converter, analog quantity is converted into to digital output, and controller is accepted the digital signal from A/D converter output, through computing, digital signal is converted to the actual weight signal of object, and is sent in display unit.
The frame for movement of described medical pain stimulation instrument, comprise motor 1, screw rod 2, slide rail 3, slide unit 4, elastic copper sheet 5, copper bar 6, ergograph 7.
Described motor 1 has connected screw rod 2, and motor 1 rotates and can drive screw rod 2 rotations.The two ends of described slide unit 4 are placed in slide rail 3, can slide up and down, and described slide unit 4 middle parts are porose, are carved with screw thread in hole, the screw rod 2 on motor, and through this hole, motor 1 drives screw rod 2 and rotates, and promotes slide unit and moves.
Described slide unit 4 belows are the good copper sheet 5 of elasticity fixedly, described copper sheet 5 below fixed copper bars 6.Four foil gauges (R1, R2, R3, R4) that distribute on described ergograph 7, carry out the detected pressures size.
