Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and specifically relates to a wearable small animal electrical stimulation device. Background Art

[0002] Animal electrical stimulation is a commonly used technique in neuroscience research. It can be used to study animal emergency behavior, learning and memory, pain perception, and motor function. Electrical stimulation can be adjusted through different modes and parameters to meet different experimental needs.

[0003] There are a variety of animal electrical stimulation devices on the market, which usually have the functions of constant voltage and constant current stimulation, and the current and voltage values ​​can be adjusted. Paired associative stimulation (PAS) is a non-invasive brain stimulation program. PAS consists of two repeated stimulations and time pairings: central-peripheral pairing; the long-term potentiation (LTP) and / or long-term depression (LTD) caused by paired associative stimulation can improve the plasticity of related brain areas and promote recovery according to Hebbian learning theory; in the field of basic research animal experiments, since magnetic stimulation devices cannot accurately stimulate the brain areas of small animals, electrical stimulation or optogenetic regulation are often used to conduct brain regulation-related experiments.

[0004] It is difficult to perform training while stimulating during use with existing electrical stimulators. In practical applications, small animals need to be able to move freely, but existing methods are mostly invasive. Electrode needles and electrode wires prevent small animals from moving, and the animals need to be anesthetized or restrained, which makes the research application value not high. Secondly, even if the small animals are able to move, paired electrodes are required to cover the small animals' heads, spines and limbs during electrical stimulation. Small animals are prone to stress reactions when receiving electrical stimulation, and are prone to bursts and pulling on the electrodes, causing the connectors on the electrodes to loosen or even detach from the terminals on the electrical stimulator, leaving gaps between the connectors and the terminals, which are prone to water seepage and dust accumulation, thereby affecting the stability of the electrical stimulator and the accuracy of the experiment.

The air cushion ring expands and drives multiple sealing rings to embed into the sealing groove outside the power socket, so as to achieve the purpose of sealing connection between the fixed sleeve and the power socket, and prevent the gap between the fixed sleeve and the power socket from causing In the case of water seepage and dust accumulation, as the power socket continues to be inserted, the two locking components on the power socket contact one side of the fixed sleeve, and the end of the card strip in the locking component can retract into the slide after being compressed. When the card strip moves to the slot, the elastic force of the second spring supports the L-shaped card strip to be inserted into the slot, thereby achieving the purpose of locking the position of the power socket, preventing small animals from having a stress response when being electrically stimulated, thereby pulling the wires and causing the power socket and the terminal to loosen, thereby ensuring the stability of the use of the electric stimulation device and the experimental accuracy.

Because the flexible strip, the head patch and the limb patch are respectively installed with electrode sheets, the electrode sheets are in contact with various parts of the small animal's body and are connected to the wires through electrode wires. Then, by starting the electric stimulation control box, the current is transmitted to various parts of the small animal's body through the electrode sheets, abandoning the traditional invasive method of conducting experiments, thereby improving the application value of the research.

[0017] 3. In the present invention, by squeezing the two pressing blocks, the two pressing blocks drive the two clamping strips to approach each other through the two sliding columns. The clamping strips can be separated from the clamping slots during the movement, thereby releasing the locking state between the power socket and the fixed sleeve. In the process of pulling out the power socket, the pressure ring will drive the movable end of the piston cylinder to extend under the elastic force of the first spring, so that the piston cylinder can extract the gas in the air cushion ring through the air pipe, and the air cushion ring will return to its original state until the power socket is completely separated from the fixed sleeve, so that the power socket can be removed from the wiring terminal conveniently, thereby improving the convenience of operation.

[0036] The working principle of the present invention is:

[0037] When in use, the spine patch 101 is glued to the back of the small animal, and the head patch 104 is glued to the head of the small animal. The spine patch 101 and the head patch 104 are connected by the flexible strip 103 to ensure the flexibility of the small animal's head. Then, the four limb patches 105 are glued to the limbs of the small animal. With the setting of the strap 106, the limb patches 105 and the spine patch 101 can be firmly fixed. The flexible strip 103, the head patch 104 and the limb patches 105 are respectively installed with electrode sheets 107. The electrode sheets 107 are in contact with various parts of the small animal's body and are connected to the wire 9 through the electrode wire. Then, by starting the electrical stimulation control box 1, the electrical stimulation is stimulated. The current is transmitted to various parts of the small animal's body through the electrode sheet 107, and the electrical stimulation control box 1 has a microcontroller module and a constant current module. The microcontroller module adopts an STM32 series microcontroller, and the input voltage is 3.3-9V and is connected to the function key 4 and the display screen 3.

At the same time, the constant current module is connected to the current intensity knob 5 to adjust the output current of the electrical stimulation. The flow achieves microsecond-level timing control of electrical stimulation pairing, which fully meets the experimental needs of researchers. After completing the electrical stimulation work on small animals, the two pressing blocks 134 are squeezed, so that the two pressing blocks 134 drive the two card strips 131 to approach each other through the two sliding columns 133. The card strips 131 can be separated from the card slot 14 during the movement, thereby releasing the locking state between the power socket 801 and the fixed sleeve 6.
