Embodiment 1

[0031] figure 1 It is a schematic structural diagram of a rat paw peripheral muscle tension measuring device provided in Embodiment 1 of the present invention. Such as figure 1 As shown, the rat paw peripheral muscle tension measuring device provided by Embodiment 1 of the present invention includes:

[0032] Paw immobilization device 10, is used for fixing a paw of experimental rat, and does not limit the rotation of this paw around its ankle joint;

[0033] An expansion connection device 20, one end of the expansion connection device 20 is fixedly connected with the claw fixing device 10;

[0034] A signal acquisition device 30, the signal acquisition device 30 is fixedly connected with the paw fixing device 10 and the expansion connection device 20 respectively, and can collect the voltage signal of the peripheral muscle tension of the paw when the paw rotates around the ankle joint;

[0035] The signal processing unit 40 is connected with the signal acquisition device 3...

Embodiment 2

[0049] Figure 4 It is a schematic flowchart of a method for measuring peripheral muscle tension of rat paws provided by Example 2 of the present invention. Such as Figure 4 As shown, the method for measuring the peripheral muscle tension of rat paws provided by the second embodiment of the present invention can be realized by the device for measuring the peripheral muscle tension of rat paws provided by the above-mentioned embodiment 1 of the present invention. The measuring method specifically includes the following steps:

[0050] Step 401, fixing one paw of the experimental rat with the paw fixing device, but not restricting the rotation of the paw around its ankle joint;

[0051] Step 402, connect the paw fixing device with the rotating shaft of the servo motor, and enable the torque of the rotating shaft to be transmitted to the paw fixing device, and drive the rat's paw to rotate around its ankle joint within a certain angle range. It should be noted that : For the a...

Abstract

The invention provides a device and a method for measuring periphery muscle tension of a rat paw, wherein the measuring device provided by the invention comprises a paw fixing device, an expansion connecting device, a signal collecting device, a signal processing unit, a servo motor, a servo driver and a microprocessor, wherein the expansion connecting device is fixedly connected with the paw fixing device; the signal collecting device is respectively fixedly connected with the paw fixing device and the expansion connecting device and can be used for collecting voltage signals of the peripheral muscle tension of the paw; the signal processing unit is connected with the signal collecting device and can be used for converting the collected voltage signals to digital signals; the servo motor is fixedly connected with the expansion connecting device and can be used for driving the paw to rotate around an ankle; the servo driver is connected with the servo motor and can be used for controlling angular displacement and/or angular velocity in the rotation of a motor spindle; and the microprocessor can be used for generating corresponding electric signals according to preset angular displacement and/or angular velocity and sending the electric signals to the servo driver. According to the device and the method measuring the periphery muscle tension of the rat paw, the measurement on the periphery muscle tension of the rat paw is realized, and the technical problem that limb muscle tension of an experimental animal model cannot be measured accurately in the prior art is solved.

Description

technical field [0001] The invention relates to a muscle tension measurement technology of an experimental animal model, in particular to a device and method for measuring peripheral muscle tension of rat paws. Background technique [0002] Stroke is currently the main cause of death and disability among middle-aged and elderly people. It is listed as the world's three major causes of death together with heart disease and malignant tumors. It has high morbidity, disability, mortality, recurrence and concurrent complications. Symptoms and other characteristics. [0003] During the recovery period after a stroke, there will be changes in limb muscle tone, which are specifically manifested as increased limb muscle tone or limb muscle spasm. The clinical feature of limb muscle spasm is that the limb muscles produce resistance to passive movements of different speeds, and the resistance increases in the same proportion, that is, the higher the speed of passive movement, the grea...
