The first end of the drainage tube is close to the temperature stimulation head and communicates with the inner cavity of the temperature stimulation head. The second end of the drainage tube is communicated with the first liquid storage tank. The first liquid storage tank is communicated with the outlet of the first pump body. There is a radial gap between the inner wall of the cavity of the external temperature stimulation rod and the outer wall of the drainage tube.

The heat exchange connection includes a first connecting pipe and a second connecting pipe. The outlet of the heat exchange coil and the inlet of the second liquid tank are connected sequentially through the second pump body and the first connecting pipe. The inlet of the heat exchange coil and the outlet of the second liquid tank are connected through the second connecting pipe.

[0010] More preferably, the heat exchange assembly further includes a heat dissipation unit installed in the second housing, the heat dissipation unit including a heat sink and a cooling fan, the bottom surface of the heat sink being attached to the outer wall of the heat exchange fluid tank, and the cooling fan being disposed on the top surface of the heat sink.

[0011] Preferably, the device further includes an electrical stimulation assembly, which includes: an electrical stimulation rod sleeved on the temperature stimulation rod, one end of the electrical stimulation rod being a thermoelectric stimulation head, the thermoelectric stimulation head being thermally conductively insulated from the temperature stimulation head; an integrated circuit board installed inside the first housing, the output end of the integrated circuit board being electrically connected to the electrical stimulation rod; and conductive electrodes electrically connected to the integrated circuit board.

[0016] By separating the temperature control components into the first and second housings, the weight of the first housing is effectively reduced, lessening the burden on the patient. Furthermore, the first housing can be made flatter and narrower with smaller lateral dimensions, reducing visual obstruction when doctors observe the oral cavity or when patients observe their own oral reflexes in a mirror, thus facilitating a more comprehensive and accurate assessment of the patient's swallowing function. The first pump can efficiently and quickly pump the liquid medium from the first reservoir directly into the inner cavity of the temperature stimulation head, accelerating medium circulation and ensuring the reliability of the temperature stimulation head. The temperature stimulation rod is designed with a double-layer structure including a drainage tube and an external temperature stimulation rod. This allows the return pipe of the liquid medium to form a heat-insulating protective layer between the liquid medium and the inlet drainage tube and the external atmosphere, better reducing heat exchange between the liquid medium in the drainage tube and the external environment. This ensures that the temperature stimulation head can better maintain the preset temperature, increasing the effective working time of the temperature stimulation device and reducing energy consumption for cooling and heating.

[0025] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other.

[0026] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the illustrations only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0027] Temperature stimulation devices can provide hot and cold stimulation to patients with swallowing disorders. Existing temperature stimulation devices have problems such as complex structure, large size, and difficulty in carrying. Some temperature stimulation devices that are easier to carry have problems such as heavy hand-held parts, which are not conducive to prolonged use by patients, and large lateral dimensions, which obstruct the view. In order to address the above-mentioned defects of the prior art, this utility model provides a temperature stimulation device that is easier to carry, has a lighter hand-held part, a smaller lateral dimension, and less obstruction of the view.

[0028] Please see Figures 1-6In an optional embodiment of this utility model, the split-type temperature stimulation device includes: a temperature stimulation rod 100, one end of which is a temperature stimulation head 121; a first housing 200; a temperature control component, which is installed inside the first housing 200 and connected to the second end of the temperature stimulation rod 100, the first end of the temperature stimulation rod 100 extending out of the first housing 200, and the temperature control component is configured to regulate the temperature of the temperature stimulation head 121 to a preset temperature by inputting a liquid medium of a preset temperature into the cavity of the temperature stimulation rod 100; a second housing 300; and a heat exchange component, which includes a heat exchange end, a heat exchange connector, and a heat exchange terminal, the heat exchange terminal being located inside the first housing 200 and connected to the temperature control component, one end of the heat exchange connector being connected to the heat exchange terminal. The other end of the heat exchange connector is connected to the heat exchange end installed in the second housing 300. The heat exchange end is configured to adjust the temperature of the heat exchange end to a preset temperature through the heat exchange connector. In a specific embodiment, the temperature control component can maintain the temperature of the temperature stimulation rod 100 by electric heating or liquid cooling. The temperature control component can also be adjusted by liquid cooling or power supply components. In order to increase the heat conduction or cooling effect, the temperature stimulation rod 100 can be made of stainless steel, copper, aluminum, silver or other materials. In addition, in order to facilitate the use of the temperature stimulation device by the patient, the distance between the first housing 200 and the second housing 300 can be set such that when the patient holds the first housing 200 and inserts the temperature stimulation head 121 connected to the first housing 200 into the patient's mouth to provide hot and cold stimulation, the second housing 300 can be placed on a table or the ground.

[0029] By separating and assembling the temperature control components into two housings, the weight of the first housing 200 held in hand is effectively reduced, alleviating the burden on the patient. In addition, the first housing 200 can be made into a flatter and narrower outer shell with a smaller lateral dimension, reducing visual obstruction when doctors observe the oral cavity or when patients observe their own oral cavity reflexes through a mirror, thus making it easier to make a comprehensive and accurate judgment on the patient's swallowing function.

[0030] Please see Figure 2 , Figure 4 , Figure 5 In an optional embodiment of this utility model, the temperature control component includes:

[0031] The liquid storage unit includes a first liquid storage tank 410 and a first pump body 420. The temperature stimulation rod 100 has a first cavity 111. The first liquid storage tank 410 can pump a liquid medium at a preset temperature into the cavity of the temperature stimulation rod 100 through the first pump body 420. In a specific embodiment, to increase safety and prevent liquid leakage from harming the patient, a mixture of medical silicone oil, pure water, or water can be used as the liquid medium. The semiconductor temperature control chip unit includes at least one semiconductor temperature control chip 43. 0. The cooling or heating surface of the semiconductor temperature control chip 430 is attached to the outer wall of the first liquid storage tank 410. In a specific embodiment, in order to increase the heating or cooling effect, semiconductor temperature control chips 430 can be attached to multiple side walls of the first liquid storage tank 410 respectively. In this embodiment, in order to balance the heating and cooling effect and make the first housing 200 have a smaller lateral size, the first liquid storage tank 410 is made into a flat and narrow box structure, and semiconductor temperature control chips 430 are attached to the two large side surfaces of the first liquid storage tank 410 respectively.

[0032] By pumping a liquid medium at a preset temperature into the cavity of the temperature stimulation rod 100, the temperature stimulation rod 100 has a more compact structure compared to other methods such as external electric heating of the temperature stimulation rod 100, and also improves the safety of use. The semiconductor temperature control chip 430 can efficiently heat or cool, giving the temperature stimulation device a faster temperature adjustment response speed.

[0033] Please see Figure 5 , Figure 6 In an optional embodiment of this utility model, the temperature stimulation rod 100 includes a hollow drainage tube 110 and an external temperature stimulation rod 120 coaxially sleeved. Specifically, the drainage tube 110 has an axially penetrating cavity 111. The first end of the external temperature stimulation rod 120 is closed as a temperature stimulation head 121. The first end of the drainage tube 110 is close to the temperature stimulation head 121 and communicates with the inner cavity of the temperature stimulation head 121. For a more detailed embodiment, please refer to [reference needed]. Figure 6 As shown, an axial gap 122 is left between the first end of the drainage tube 110 and the inner cavity of the temperature stimulation head 121. Alternatively, a drainage groove or drainage hole can be opened on the temperature stimulation head 121 or the drainage tube 110. The second end of the drainage tube 110 is connected to the first liquid storage tank 410. The first liquid storage tank 410 is connected to the outlet 422 of the first pump body. There is a radial gap 123 between the inner wall of the cavity of the external temperature stimulation rod 120 and the outer wall of the drainage tube 110. One end of the radial gap 123 is connected to the inner cavity of the temperature stimulation head 121, and the other end is connected to the inlet 421 of the first pump body.

[0034] In a specific embodiment, in order to facilitate the installation and arrangement of the external temperature stimulation rod 120, a three-way pipe connector 560 can be provided on the first liquid storage tank 410. The first connector end of the three-way pipe connector 560 is fixed on the first liquid storage tank 410, the second connector end allows the external temperature stimulation rod 120 to be inserted, and the third connector end is connected to the pipe whose bottom end is connected to the inlet 421 of the first pump body. The top end of the pipe is fitted onto the third connector end and extends into the radial gap 123.

[0035] The design of the temperature stimulation rod 100 allows the first pump outlet 422 to pump the liquid medium through the first reservoir 410 into the cavity 111 of the drainage tube 110. The semiconductor temperature control chip 430 attached to the outer wall of the first reservoir 410 heats or cools the liquid medium. After heating or cooling, the liquid medium with a preset temperature continues to flow through the cavity 111 into the cavity of the temperature stimulation head 121, thereby regulating the temperature of the temperature stimulation head 121. Heat exchange occurs between the temperature stimulation rod 100 and the oral cavity. After the temperature decays, the liquid medium can flow through the axial gap 122 into the radial gap 123, and then be pressed into the first pump body outlet 422 through the first pump body inlet 421 to continue the circulation. The double-layer structure design of the temperature stimulation rod 100 allows the return pipe of the liquid medium to form a heat insulation protection layer with the outside atmosphere to the inlet pipe, which can ensure that the liquid medium in the cavity 111 can be kept within the preset temperature range for a longer time. This not only increases the effective working time of the temperature stimulation device, but also reduces the energy consumption of cooling and heating.

[0036] Please see Figure 2 In an optional embodiment of this utility model, the heat exchange terminal includes at least one second liquid storage tank 440. The second liquid storage tank 440 is attached to the heating or cooling surface of the semiconductor temperature control chip 430 away from the outer wall of the first liquid storage tank 410. The second liquid storage tank 440 contains a liquid medium for cooling or heating the heating or cooling surface. In a specific embodiment, for safety reasons, the liquid medium in the second liquid storage tank 440 can also be medical silicone oil. In order to make the first housing 200 have a smaller lateral dimension, the second liquid storage tank 440 is also made into a flat and narrow box structure. Heat dissipation holes 231 can be opened on the first housing 200 to allow the heat of the liquid medium in the second liquid storage tank 440 to exchange with the atmospheric environment.

[0037] The second liquid storage tank 440 unit ensures that the semiconductor temperature control chip 430 can work reliably and effectively, and the first pump body 420 can efficiently and quickly pump the liquid medium in the first liquid storage tank 410 into the cavity 111, ensuring the working reliability of the temperature stimulation head 121.

[0038] Please see Figure 2 , Figure 3In an optional embodiment of this utility model, the heat exchange end includes: a heat exchange coil 510, a second pump body 520, and a heat exchange liquid tank 530. The heat exchange liquid tank 530 stores a liquid medium, and the heat exchange coil 510 is immersed in the heat exchange liquid tank 530. The heat exchange connection includes a first connecting pipe 610 and a second connecting pipe 620. The outlet of the heat exchange coil 510 is connected to the inlet of the second liquid storage tank 440 in sequence through the second pump body 520 and the first connecting pipe 610. The inlet of the 0 is connected to the outlet of the second liquid storage tank 440 through the second connecting pipe 620. In a specific embodiment, in order to have a higher degree of freedom in adjusting the position between the first housing 200 and the second housing 300, the first connecting pipe 610 and the second connecting pipe 620 can be flexible pipes of appropriate length made of materials such as polyethylene. The heat exchange coil 510 can enable the liquid medium to fully exchange heat with the heat exchange liquid tank 530, effectively ensuring that the temperature of the liquid medium in the second liquid storage tank 440 is within the effective working range.

[0039] Please see Figure 1 In an optional embodiment of this utility model, the heat exchange assembly further includes a heat dissipation unit installed in the second housing 300. The heat dissipation unit includes a heat sink 540 and a cooling fan 550. The bottom surface of the heat sink 540 is attached to the outer wall of the heat exchange liquid tank 530, and the cooling fan 550 is disposed on the top surface of the heat sink 540. The heat dissipation unit can cool the heat exchange liquid tank 530. In a specific embodiment, in order to ensure that the cooling fan 550 works effectively, a heat dissipation through hole 231 can be opened on the second housing 300.

[0040] Please see Figures 4-6 In an optional embodiment of this utility model, the temperature stimulation device further includes an electrical stimulation component, the electrical stimulation component comprising:

[0041] An electrical stimulation rod 710 is sleeved on the temperature stimulation rod 100. One end of the electrical stimulation rod 710 is a temperature stimulation head 711, which is thermally conductively insulated from the temperature stimulation head 121.

[0042] An integrated circuit board is installed inside the first housing 200, and the output end of the integrated circuit board is electrically connected to the electrical stimulation rod 710;

[0043] Conducting electrode, which is electrically connected to the integrated circuit board.

[0044] The electrical stimulation component enables the temperature stimulation device to not only provide hot and cold stimulation to the patient's mouth, but also to provide voltage stimulation as needed, thus expanding the device's functionality.

[0045] In an optional embodiment of this utility model, the conductive electrode includes a touch conductive electrode and / or a conductive patch. When the patient uses the device to perform electrical stimulation or thermoelectric mixed stimulation, he / she can hold the touch conductive electrode on the handle tightly with his / her hand, so that the thermoelectric stimulation head 711, the human body, and the touch conductive electrode form a current circuit. When the doctor uses the device to stimulate the patient, the conductive patch can be attached to the patient's body to form a current circuit.

[0046] In an optional embodiment of this utility model, the thermoelectric stimulation rod 710 is detachably fitted onto the temperature stimulation rod 100. This allows the thermoelectric stimulation rod 710 to be replaced for different patients, thus avoiding cross-infection and hygiene problems. Furthermore, the replaced thermoelectric stimulation rod 710 is easier to clean, convenient for personal storage and maintenance, and can be reused multiple times. An insulating and thermally conductive layer is filled between the inner wall of the thermoelectric stimulation head 711 and the outer wall of the temperature stimulation head 121. This insulating and thermally conductive layer is a thermally conductive silicone pad, graphite thermally conductive sheet, or graphene thermally conductive sheet fitted with heat-shrink tubing. This insulating and thermally conductive layer has good thermal conductivity, while the heat-shrink tubing provides elasticity. Therefore, when the thermoelectric stimulation rod 710 is fitted onto the temperature stimulation rod 100, a buffer zone is formed between the inner wall of the thermoelectric stimulation head 711 and the outer wall of the temperature stimulation head 121, providing an interference fit and ensuring a tight fit. For a secure installation of the insulating and thermally conductive layer, please refer to [link to relevant documentation]. Figure 6 An annular groove 124 is provided on the outer wall of the temperature stimulation head 121 to fix and install the insulating heat-conducting layer.

[0047] Please see Figure 5 In an optional embodiment of this utility model, the first liquid storage tank 410 is provided with a curved flow channel 411 that connects the first pump body outlet 422 and one end of the drainage pipe 110, which is coiled in the inner cavity of the first liquid storage tank 410, so as to increase the heat exchange contact area between the liquid medium and the semiconductor temperature control chip 430 and enhance the heat exchange effect.

[0048] In an optional embodiment of this utility model, in order to accurately control the temperature at the temperature stimulation head 121, a temperature sensor can be set at the temperature stimulation head 121, or a temperature sensor can be set at the first pump body inlet 421 and the first pump body outlet 422.

[0049] In summary, the temperature stimulation device of this application effectively reduces the weight of the first housing 200 by separating the temperature control components into the first housing 200 and the second housing 300, thus alleviating the burden on the patient. Furthermore, it allows the first housing 200 to be made with a smaller lateral dimension, reducing visual obstruction when doctors observe the oral cavity or when patients observe their own oral reflexes through a mirror, thereby facilitating a more comprehensive and accurate assessment of the patient's swallowing function. The temperature stimulation rod 100 is designed with a double-layer structure including a drainage tube 110 and an external temperature stimulation rod 120, allowing the return pipe of the liquid medium to form a thermal insulation layer between the return pipe and the inlet pipe and the external atmosphere. This ensures that the liquid medium within the cavity 111 can remain within the preset temperature range for a longer period, increasing the effective working time of the temperature stimulation device and reducing energy consumption for cooling and heating.
