Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and specifically relates to a wearable electric stimulation device for small animals. Background Art

[0002] Animal electrical stimulation is a commonly used technique in neuroscience research, used to study animal stress response, learning and memory, pain perception, and motor function. Electrical stimulation can be adjusted using different modes and parameters to suit diverse experimental needs.

[0003] There are currently 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] Existing electrical stimulators are difficult to use for training while stimulating. 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 need to be performed under anesthesia or restraint, making their research application value low. 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, resulting in 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.

[0015] 1. In the present invention, the power socket on the power connection assembly is inserted into the fixed sleeve, so that the power socket contacts and pushes the pressure ring, and at the same time, the terminal is plugged into the inside of the power socket to achieve the purpose of connection. The pressure ring squeezes the telescopic ends of the multiple piston cylinders to increase the internal air pressure, and the gas is introduced into the air cushion ring through the air pipe. The air cushion ring expands and drives multiple sealing rings to be embedded in the sealing groove outside the power socket, thereby achieving the purpose of sealing connection between the fixed sleeve and the power socket, and preventing the fixed sleeve and the power socket from having a gap. In the event of water seepage and dust accumulation, as the power socket continues to be inserted, the two locking components on the power socket come into contact with one side of the fixed sleeve, and the end of the card strip in the locking component can be retracted into the slide after being compressed.

Because the flexible strip, head patch and limb patch are respectively equipped with electrode patches, the electrode patches 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 patches, abandoning the traditional invasive method of experiment, 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, which makes it convenient to remove the power socket from the terminal block, thereby improving the convenience of operation.

[0036] The working principle of this utility model 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 a 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 electric stimulation control box 1, the electric stimulation control box 1 is activated. The current is transmitted to various parts of the small animal's body through the electrode sheet 107. The electrical stimulation control box 1 includes 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 button 4 and the display 3. The pins of the STM32 series microcontroller are connected to the constant current module to output electrical stimulation with an intensity of 0-25mA. The output waveforms are square wave, sine wave, triangle wave, and simulated noise. The pins of the STM32 series microcontroller are connected to the function button 4.

The function button 4 is connected to the microcontroller, and the high and low levels are input to cooperate with the microcontroller module to adjust the stimulation parameters. The display 3 can display the parameters and the remaining time. 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 electrical stimulation pairing timing control, which fully meets the experimental needs of researchers. After completing the electrical stimulation work on the small animal, the two pressing blocks 134 are squeezed, so that the two pressing blocks 134 drive the two card strips 131 to move closer to each other through the two slide 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. In the process of pulling out the power socket 801, the pressure ring 111 is affected by the elastic force of the first spring 113 to drive the movable end of the piston cylinder 112 to extend, so that The piston cylinder 112 can extract the gas in the air cushion ring 115 through the air pipe 114, and the air cushion ring 115 returns to its original state until the power socket 801 is completely separated from the fixing sleeve 6. When connecting the terminal 7 and the power socket 801, the power socket 801 is inserted into the fixing sleeve 6, so that the power socket 801 contacts and pushes the pressing ring 111. At the same time, the terminal 7 is plugged into the inside of the power socket 801 to achieve the purpose of connection. The pressing ring 111 squeezes the telescopic ends of the multiple piston cylinders 112 to increase the internal air pressure, and the gas passes through the air pipe 114 is guided into the air cushion ring 115, which expands and drives multiple sealing rings 116 to embed into the sealing groove 802 outside the power socket 801, achieving a sealed connection between the fixing sleeve 6 and the power socket 801. As the power socket 801 continues to be inserted, the end of the clamping strip 131 is compressed and can retract into the slideway 12. When the clamping strip 131 moves to the clamping groove 14, the elastic force of the second spring 132 allows the L-shaped clamping strip 131 to be clamped into the clamping groove 14, achieving the purpose of locking the connection with the power socket 801.
