Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to the structure of a portable household cryotherapy instrument. Background Art

[0002] In the field of rehabilitation medicine, seeking innovative and effective treatment methods for various dysfunctions caused by injuries and diseases has always been an important research direction. With the in-depth understanding of the mechanism of cryotherapy and the continuous progress of technology, its application in the field of rehabilitation has gradually attracted attention. In the early stage, the means of rehabilitation treatment were relatively limited, mainly focusing on physical therapy, exercise training, and traditional drug treatment. However, for some problems such as chronic pain, inflammation, and sports injuries, the effects of these methods are sometimes not ideal. Cryotherapy provides a new way to solve these problems due to its unique physiological effects. Research has found that low temperature can effectively reduce the inflammatory response, relieve pain, and promote tissue repair and regeneration. For example, in the rehabilitation of sports injuries, cryotherapy can quickly reduce the temperature of the injured area, constrict blood vessels, reduce bleeding and swelling, thereby alleviating pain and promoting early recovery. In addition, with the improvement of people's requirements for rehabilitation effects and the quality of life of patients, non-invasive treatment methods with few side effects and rapid symptom relief are highly favored. Cryotherapy just meets these requirements. It does not require complex surgical operations, has a relatively small burden on the patient's body, and can show certain therapeutic effects in a relatively short period of time.

[0003] A cryotherapy instrument usually consists of the following main parts: Refrigeration system: This is the core component for generating low temperature. Common refrigerants include liquid nitrogen, carbon dioxide, etc. It includes components such as a compressor, a condenser, and an evaporator, and realizes refrigeration through a series of thermodynamic processes. Temperature control system: Used to accurately monitor and adjust the temperature of the treatment site. It consists of a temperature sensor, a controller, and an adjustment device to ensure that the temperature is within the set safe and effective range. Treatment probe: The part that directly contacts the patient's body for treatment. Its shape and size vary according to the treatment site and requirements, such as needle-shaped, spherical, flat-shaped, etc. Gas transmission system: If gas refrigerants such as liquid nitrogen or carbon dioxide are used, corresponding pipelines and valves are required to control the flow and pressure of the gas. Operation console: Provides a user operation interface for setting treatment parameters such as temperature, treatment time, etc., and displays relevant information during the treatment process, such as real-time temperature, treatment progress, etc. Power supply system: Provides power support for the entire instrument to ensure its normal operation. Safety protection devices: Such as over-temperature protection, pressure protection, leakage protection, etc., to ensure the safety of patients and operators. Shell and bracket: Play a role in protecting internal components and providing stable support.

[0004] The existing operation process of cryotherapy equipment is relatively cumbersome and requires professional trained operators to master proficiently, which increases the usage difficulty and labor cost. Moreover, the existing equipment is large and bulky, which is not conducive to use in some places with limited space and is not convenient to carry for mobile treatment. Summary of the Utility Model
