[0028] The high-temperature stimulation module of a composite somatosensory stimulator for giving experimental animals mechanical force and high temperature in this embodiment can set different total stimulation duration, frequency, stimulation intensity, etc. according to requirements. For example, it is necessary to give a high-temperature stimulus with a total stimulus duration of 2s, a frequency of 2Hz, and 0.3s heating / 0.2s cooling.
[0029] First, code in advance on the programming software of the control module to adjust the output voltage of the regulated power supply, and the corresponding output port output2-1 / output2-2 on the data acquisition card. The settings are as follows: [Output port name]=output2-1 / output2-2, [On-circuit duration]=0.3, [Off-circuit duration]=0.2, [Number of stimulation cycles]=4. Before starting, the high temperature stimulation module is in the off state. Timing starts from the starting point, the output port output2-1 / output2-2 sends out a...

The invention discloses a composite somatosensory stimulator giving mechanical force and high temperature for experimental animals. The composite somatosensory stimulator comprises a control module, adata collection module, a power supply module, a relay module, a lifting module, a high temperature stimulation module and a mechanical force module, wherein the control module is connected with oneend of the data collection module; the other end of the data collection module is connected with the relay module; the other end of the relay module is connected with the power supply module; the module is also connected with the high temperature stimulation module and the mechanical force module; the high temperature stimulation module and the mechanical force module are arranged to act an objectto be tested at the same time; the mechanical force module is arranged to be connected with the lifting module; and the high temperature stimulation module and the mechanical force module are both connected with the power supply module. The composite somatosensory stimulator giving mechanical force and high temperature for experimental animals is high in manoeuvrability, stable in stimulation, simple in device and low in cost, and more importantly, can meet time precision requirements of test.
Description
technical field [0001] The invention relates to the field of somatosensory stimulation devices, in particular to a composite somatosensory stimulator for giving experimental animals mechanical force and high temperature. Background technique [0002] In the field of neurobiology, somatosensory perception research has always been an important direction. After receiving somatosensory stimulation, the psychophysical test results reported subjectively by the subjects and the electrical signals of the cerebral cortex objectively recorded by the instrument are the two major research methods. These research methods have important guiding significance for exploring the somatosensory information processing mode of the brain. For example, in the field of dental restoration, the somatosensory stimulation of the affected tooth or dental implant is an important part of testing the vitality of the tooth. [0003] In terms of somatosensory stimulation, there are various forms such as vib...
