Description

Technical Field

[0001] This utility model relates to the field of cryotherapy technology, and in particular to a temperature control device for an ultra-low temperature cryotherapy machine. Background Technology

[0002] Cryotherapy is a treatment method that uses physical agents (cold water, ice, evaporative cryogens, etc.) that are colder than body temperature to stimulate the body or mucous membranes, thereby achieving effects such as cooling, pain relief, hemostasis, reduction of inflammatory edema and exudation, and promotion of wound repair and early wound healing. It is commonly used for orthopedic limb trauma, soft tissue injuries, and postoperative patients. Cold compresses to the affected area are effective in reducing tissue swelling, reducing inflammation and pain, decreasing local bleeding, relieving spasms, and promoting recovery.

[0003] In the field of sports medicine, cryotherapy is generally considered to be the standard treatment for emergency treatment or rehabilitation of sports injuries. However, current cryotherapy equipment mainly consists of local cold baths. For fatigue relief, ice baths or cold water baths are often used, which are very stimulating to the human body, and many people cannot tolerate them. They also have side effects and limited therapeutic effects. Utility Model Content

[0050] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0051] like Figure 1 As shown, this embodiment of the present invention provides a temperature control device for an ultra-low temperature cryotherapy machine, including: a temperature control chamber, a pressure control component 2, a recovery pipe 3, a heat exchange medium 4, a temperature control component 5, a temperature sensor 6, and a controller 7. The temperature control chamber 1 is divided into a delivery channel 12 and a control area 13 by a delivery pipe 11. The pressure control component 2 is mounted on the temperature control chamber and communicates with the delivery channel 12. The heat exchange medium 4 fills the control area 13 of the temperature control chamber. The temperature control component 5 communicates with the control area 13. The temperature sensor 6 is mounted on the delivery pipe 11. The controller 7 is electrically connected to the pressure control component 2, the temperature control component 5, and the controller 7.

[0052] During cryotherapy, the liquid nitrogen in the storage tank needs to be heated to prevent frostbite to the user. During the heating process, the liquid nitrogen used by the cryotherapy machine is circulated into the delivery channel 12 for heat exchange, and then heated again through the heat exchange medium 4 located in the temperature control box. During the heating process, the temperature sensor 6 located in the delivery channel 12 monitors the temperature in real time, and only delivers the nitrogen to the cryotherapy machine once the preset temperature is reached.

[0053] To prevent excessive pressure in the conveying channel 12 during use, which could damage the conveying pipe 11, a pressure control component 2 is provided to release pressure when the pressure exceeds its preset value.

[0054] The heat exchange medium 4 is heated by the temperature control component 5, which facilitates the rapid heating of the liquid nitrogen in the transport channel 12 to the preset temperature.

[0055] To achieve automatic control, a controller 7 is provided, which is electrically connected to the pressure control component 2, the temperature control component 5, and the controller 7.

[0056] In one embodiment, such as Figure 2 As shown, in order to improve the heat preservation performance of the temperature control box, an insulation layer 8 is provided on the outer wall of the temperature control box.

[0057] In one embodiment, such as Figure 1 As shown, the pressure control assembly 2 includes a connecting pipe 21 and a pressure valve 22. One end of the connecting pipe 21 is connected to the delivery pipe 11, and the other end is connected to the recovery device. The pressure valve 22 is mounted on the connecting pipe 21, and the controller 7 is electrically connected to the pressure valve 22.

[0058] When the pressure in the delivery pipe 11 exceeds the preset value, the controller 7 controls the pressure valve 22 to open, and the liquid nitrogen in the delivery pipe 11 enters the recovery device through the connecting pipe 21, thus avoiding waste of liquid nitrogen and completing the pressure relief work.

[0059] In one embodiment, such as Figure 2 As shown, in order to improve heat exchange efficiency, a connecting plate 9 is provided on the outer wall of the recovery pipe 3, and the connecting plate 9 is connected to the inner wall of the conveying pipe 11. The connecting plate 9 can not only increase the contact area with liquid nitrogen, but also fix the recovery pipe and prevent the recovery pipe 3 from shaking during the conveying of liquid nitrogen.

[0060] In one embodiment, such as Figure 3 As shown, in order to further improve the heat exchange efficiency between the recovery pipe 3 and liquid nitrogen, a heat exchange component 10 is provided on the outer wall of the recovery pipe 3.

[0061] In one embodiment, such as Figure 1As shown, the temperature control assembly includes: a storage tank 51, a heater 52, a medium delivery pipe 53, a medium recovery pipe 54, a delivery pump 55, and a control valve 56. The heater 52 is installed inside the storage tank 51. One end of the medium delivery pipe 53 is connected to the storage tank 51, and the other end is connected to the control area 13. One end of the medium recovery pipe 54 is connected to the storage tank 51, and the other end is connected to the control area 13. The delivery pump 55 is installed on the medium delivery pipe 53, and the controller 7 is electrically connected to the delivery pump 55. The control valve 56 is installed on the medium recovery tank, and the controller 7 is electrically connected to the control valve 56.

[0062] During use, the heat exchange medium 4 in the storage tank 51 is heated by the heater 52, and then the heat exchange medium 4 is sent into the control zone 13 through the medium delivery pipe 53. After heat exchange, the heat exchange medium 4 returns to the storage tank 51 through the medium recovery pipe 54. During the delivery process, the delivery pump 55, under the control of the controller 7, delivers the heat exchange medium 4 to the control zone 13. At the same time, the controller 7 controls the control valve 56 to open, facilitating the return of the heat exchange medium 4 in the control zone 13 to the storage tank 51.

[0063] During the control process, the controller 7 controls the delivery flow rate of the delivery pump 55 according to the heat exchange demand, and at the same time, the regulating valve 56 adjusts the opening and closing degree of the valve according to the delivery flow rate of the delivery pump 55.

[0064] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
