Description

Technical Field

[0001] This application relates to the field of medical devices, specifically to a temperature detection device for a treatment device handle and a treatment device handle. Background Technology

[0002] In the fields of medical rehabilitation and beauty, the handpieces of various physical therapy devices are core components that directly contact human skin. From the perspective of their working principles, current therapy device handpieces mostly generate heat through resistance heating or electromagnetic induction, and temperature adjustment relies on mechanical switching of power output levels. For example, in infrared therapy devices, users typically can only select between three fixed temperature levels: low, medium, and high. The internal temperature sensor is only used for overheat protection circuitry, rather than providing real-time feedback to the user or the main control system. This "blind adjustment" mode leads to a deviation between the actual temperature in contact with the skin and the user's set value. Especially during prolonged continuous operation, the heat accumulation effect of the handpiece contacts causes the temperature to gradually rise. Clinical data shows that the surface temperature of a therapy device handpiece that has been continuously operating for more than 30 minutes increases by an average of 12%-15% compared to the initial set value. In high-temperature environments in summer or in enclosed treatment spaces, this temperature rise can reach over 20%.

[0003] In terms of usage scenarios, the risks of prolonged treatment on a fixed site are particularly prominent. Taking physiotherapy for chronic arthritis as an example, patients often need continuous heat therapy on the same pain point for 40-60 minutes. During this time, heat accumulates in the area where the handle contacts the skin. The safety hazards of heat accumulation are not limited to immediate burns, but also include the long-term risk of skin aging. Continuous subclinical heat damage accelerates the degradation of collagen in the dermis and damages the skin barrier function. Especially in the high-frequency use scenarios of beauty devices, this hidden damage may not appear for several months, leading to delayed detection.

[0004] Most mainstream therapeutic device handpieces currently use preset temperature level adjustment modes, relying on fixed parameter calibration before leaving the factory, but generally lack a real-time temperature feedback mechanism. This design flaw has exposed significant safety hazards in clinical use. Utility Model Content

[0023] This application provides a temperature detection device for the handpiece of a therapeutic instrument and a handpiece of the therapeutic instrument, which will be described in detail below.

[0024] Please refer to Figure 1 This application provides an embodiment of a therapeutic device handle temperature detection device, specifically used for detecting the temperature of the therapeutic device handle. Please refer to... Figure 2 The treatment device handle 100 is a component on the treatment device 100 used for performing treatment. For example... Figure 1 As shown, the temperature detection device for the therapeutic instrument handle 200 specifically includes: a main control module 101 mounted on the therapeutic instrument 100, a temperature detection module 102 mounted on the therapeutic instrument handle 200, and a communication module 103 mounted on the therapeutic instrument 100.

The main control chip U1, based on a pre-coded control method, controls the communication chip U2 to send a temperature control signal to the temperature control unit connected to the communication chip U2 according to the temperature sensing signal, so that the temperature of the therapeutic instrument handle is always kept within the set range by the temperature control unit, thereby realizing the real-time measurement and adjustment of the temperature of the therapeutic instrument handle 200. Since the temperature sensed by the temperature sensor U4 is the real-time temperature of the therapeutic instrument handle 200, the real-time detection and control of the temperature of the therapeutic instrument handle 200 can be realized based on this real-time temperature, solving the technical problems of untimely temperature detection and low safety of the therapeutic instrument handle in the prior art.

[0027] Please refer to Figure 3 In the embodiments of this application, the temperature sensor U4 can specifically be a non-contact infrared temperature sensor. For example...
