Description

Technical Field

[0001] This invention relates to the field of temperature detection instruments, and more specifically to a contact skin temperature detector. Background Technology

[0002] Accurate monitoring of human skin temperature is crucial in many fields, including healthcare, sports, and routine health monitoring. It is especially important to detect elevated skin temperature in certain situations. For example, continuous skin temperature monitoring helps medical personnel quickly assess changes in the condition of patients with fever; during high-intensity training or competition, elevated skin temperature in athletes may indicate overheating, fatigue, or other conditions that could negatively impact athletic performance or even endanger health.

[0003] Traditional contact skin temperature monitors mostly only have temperature measurement and display functions, and cannot provide timely warnings to users when skin temperature exceeds the normal range. When users fail to pay attention to the temperature display value in time for various reasons, they may miss the best time to deal with the situation, leading to delayed treatment or further harm to the body. Summary of the Invention

[0004] The purpose of this invention is to provide a contact skin temperature detector that solves the technical problem that traditional contact skin temperature detectors cannot promptly alert users when skin temperature exceeds the normal range.

[0005] The objective of this invention can be achieved through the following technical solutions: A contact skin temperature detector, comprising: A temperature sensing module is used to detect the temperature of the skin in contact in real time. The temperature sensing module uses a thermistor, which can quickly and accurately sense changes in skin temperature and convert the temperature signal into an electrical signal for output. The signal processing module is electrically connected to the temperature sensing module, receives the electrical signal output by the temperature sensing module, and performs amplification, filtering and analog-to-digital conversion processing to obtain a digital temperature signal that can be recognized by the microprocessor. The microprocessor, connected to the signal processing module, presets a safe temperature threshold, compares the received digital temperature signal with the preset threshold, and sends a trigger signal to the alarm module when the detected temperature exceeds the preset threshold. The alarm module is electrically connected to the microprocessor. After receiving a trigger signal, it will issue an audible and visual alarm signal to alert the user that their skin temperature is too high. The power supply module provides stable power support for the temperature sensing module, signal processing module, microprocessor, and alarm module. The power supply module uses a rechargeable lithium battery. The housing is used to install the power supply module, temperature sensing module, signal processing module, microprocessor, and alarm module.

[0006] Furthermore, mounting grooves are provided on both sides of the housing, and flexible patches are hinged in the mounting grooves. An adhesive layer is provided on one side of the flexible patch, and a surface layer is covered on the adhesive layer. In the initial state, the adhesive layer is covered and blocked by the surface layer. When needed, the surface layer is peeled off, and the two flexible patches are then pasted onto the skin to be tested.

[0007] Furthermore, the temperature sensing module is provided with a flexible contact layer on the outside. The flexible contact layer and the adhesive layer are on the same side and can contact the skin to be detected. The flexible contact layer is made of thermally conductive silicone material.

[0008] Furthermore, the flexible patch has a bendable metal strip embedded inside, and the metal strip is arranged horizontally; when applying the flexible patch, the user can bend and adjust the metal strip according to the actual shape of their skin.

[0009] Furthermore, the outer side wall of the housing is provided with a flexible skirt, and an elastic pull rope is embedded inside the flexible skirt. One end of the elastic pull rope is fixed to the damping adjustment shaft, which is rotatably disposed in the mounting groove. One end of the adjustment shaft extends out of the mounting groove and is fixed with an adjustment knob.

[0010] Furthermore, the alarm module includes an audible and visual alarm and an adaptive adjustment component. The adaptive adjustment component is used to adaptively adjust the position of the audible and visual alarm. The audible and visual alarm is covered with a dust cover. The dust cover initially closes the audible and visual alarm and opens when the audible and visual alarm is activated.

[0011] Furthermore, the adjustment and adaptation assembly includes: a mounting base, a rotating shaft, a linkage rod, and a drive unit; The top of the housing is provided with a boss, on which the mounting base is fixedly installed. A vertical groove is formed on the boss, and a drive unit is provided at the bottom of the vertical groove. The drive unit is connected to the rotating shaft. The linkage rod is fixed in the vertical groove. The mounting base is adapted to the vertical groove. The mounting base is sleeved on the rotating shaft and also slidably sleeved on the linkage rod. A spiral groove is formed on the outer surface of the rotating shaft. The rotating shaft and the mounting base are connected by a spiral drive. The audible and visual alarm is installed on the mounting base. One end of the dust cover is hinged to the mounting base by a torsion spring. The drive unit is electrically connected to the power supply module.

[0012] The beneficial effects of this invention are: (1) In this invention, the thermistor of the temperature sensing module senses changes in skin temperature, converts the temperature signal into an electrical signal, and outputs it to the signal processing module. The signal processing module amplifies, filters, and performs analog-to-digital conversion on the electrical signal to obtain a digital temperature signal, which is then transmitted to the microprocessor. The microprocessor compares the received digital temperature signal with a preset safe temperature threshold. If the threshold is exceeded, a trigger signal is sent to the alarm module. Upon receiving the signal, the alarm module emits an audible and visual alarm signal. The power supply module provides stable power support to each module: on the one hand, it realizes real-time and accurate detection and alarm functions for skin temperature, which can promptly remind users of abnormal skin temperature, thus contributing to disease prevention and health monitoring; on the other hand, the modular design allows each functional module to perform its own function, facilitating equipment maintenance and upgrades, and improving the reliability and versatility of the equipment. (2) By setting mounting grooves on both sides of the housing and connecting them with the flexible patch, when using the flexible patch, the adhesive layer of the flexible patch is peeled off and it is pasted on the skin. The hinge design of the mounting groove and the flexible patch makes it easy to adjust the patch angle to adapt to different skin parts. On the one hand, the flexible patch and the hinge installation method improve the fit between the device and the skin, ensuring that the temperature sensing module can detect the skin temperature more accurately. On the other hand, the design of the surface layer covering the adhesive layer ensures the adhesion of the adhesive layer when the patch is not in use, extends the service life of the patch, and also makes it easier for the user to operate.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figures 1-6 As shown, the present invention is a contact skin temperature detector, comprising: Temperature sensing module 1 is used to detect the temperature of the skin in contact in real time. The temperature sensing module 1 adopts a thermistor, which can quickly and accurately sense changes in skin temperature and convert the temperature signal into an electrical signal for output. Signal processing module 2 is electrically connected to temperature sensing module 1, receives the electrical signal output by temperature sensing module 1, and performs amplification, filtering and analog-to-digital conversion processing to obtain a digital temperature signal that can be recognized by microprocessor 3. The microprocessor 3 is connected to the signal processing module 2. It presets a safe temperature threshold, compares the received digital temperature signal with the preset threshold, and sends a trigger signal to the alarm module 4 when the detected temperature exceeds the preset threshold. The alarm module 4 is electrically connected to the microprocessor 3. After receiving the trigger signal, it will issue an audible and visual alarm signal to alert the user that the skin temperature is too high. The power supply module 5 provides stable power support for the temperature sensing module 1, the signal processing module 2, the microprocessor 3, and the alarm module 4. The power supply module 5 uses a rechargeable lithium battery. The housing 6 is used to install the power supply module 5, temperature sensing module 1, signal processing module 2, microprocessor 3 and alarm module 4.

[0018] In this invention, after the device is turned on, the rechargeable lithium battery in the power supply module 5 immediately supplies power to the entire system, ensuring that all components can operate normally. The thermistor in the temperature sensing module 1 is in close contact with the skin, and thanks to its extremely sensitive characteristic to temperature changes, it quickly captures subtle fluctuations in skin temperature and immediately converts the temperature signal into an electrical signal. These electrical signals are then transmitted to the signal processing module 2. The signal processing module 2 amplifies the input electrical signals, enhancing the weak original signals to a suitable amplitude for subsequent processing. Next, filtering technology is used to remove noise and interference components from the signal, making the signal purer. Finally, through analog-to-digital conversion, the analog electrical signal is accurately converted into digital signal. The temperature signal is converted into a digital temperature signal, which can be recognized and processed by the microprocessor 3. The microprocessor 3 stores a preset safe temperature threshold in advance, continuously receives the digital temperature signal from the signal processing module 2, and compares it with the preset threshold. Once the temperature signal is detected to exceed the preset threshold, the microprocessor 3 responds quickly and sends a trigger signal to the alarm module 4. After receiving the trigger signal, the alarm module 4 quickly activates the audible and visual alarm 41. The alarm immediately emits a bright flash and a high-decibel alarm sound to attract the user's attention and indicate that the skin temperature is too high. The entire workflow is closely connected and interlocked, realizing the real-time monitoring and abnormal alarm function of skin temperature.

[0019] On the one hand, compared to traditional contact skin temperature detectors that can only measure temperature, the alarm function added to this device fills a market gap. In medical settings, for patients who need to monitor their body temperature at all times, especially those who are immobile or unable to constantly monitor their temperature, it can promptly detect abnormal body temperature, giving medical staff valuable time for diagnosis and treatment, and effectively preventing delays in treatment. On the other hand, the modular design significantly improves the maintainability and scalability of the equipment. When a module fails, maintenance personnel can quickly locate and replace the corresponding module, reducing maintenance costs and time. At the same time, with the continuous advancement of technology, individual modules can be easily upgraded, such as replacing them with a higher-precision temperature sensing module 1 or a more powerful microprocessor 3, without the need for large-scale modifications to the entire equipment. This greatly extends the service life of the equipment and enables it to better adapt to the usage needs at different stages.

[0020] Furthermore, mounting grooves 61 are provided on both sides of the housing 6, and flexible patches 62 are hinged in the mounting grooves 61. An adhesive layer 63 is provided on one side of the flexible patch 62, and a surface layer 64 is covered on the adhesive layer. In the initial state, the adhesive layer is covered and blocked by the surface layer 64. When needed, the surface layer 64 is peeled off, and the two flexible patches 62 are then pasted onto the skin to be tested.

[0021] In this invention, during use, the adhesive layer 64 of the flexible patch 62 is peeled off and adhered to the skin. The hinged design of the mounting groove 61 and the flexible patch 62 facilitates adjustment of the patch angle to adapt to different skin areas. On the one hand, the flexible patch 62 and the hinged installation method improve the fit between the device and the skin, ensuring that the temperature sensing module 1 can detect skin temperature more accurately. On the other hand, the design of the adhesive layer covering the surface layer 64 ensures the adhesion of the adhesive layer when the patch is not in use, extending the service life of the patch, and also making it easier for the user to operate.

[0022] Furthermore, the temperature sensing module 1 is provided with a flexible contact layer 7 on the outside. The flexible contact layer 7 is on the same side as the adhesive layer and can contact the skin to be detected. The flexible contact layer 7 is made of thermally conductive silicone material.

[0023] In this invention, the flexible contact layer 7 is made of thermally conductive silicone, which can efficiently transfer the heat from the skin to the temperature sensing module 1 when in contact with the skin. At the same time, its flexibility improves the user's comfort. On the one hand, the good thermal conductivity of the thermally conductive silicone ensures that the temperature sensing module 1 can quickly and accurately sense changes in skin temperature, improving the accuracy of detection. On the other hand, the flexible design increases the user's comfort when wearing the device, making the device more suitable for long-term wear and expanding the device's usage scenarios.

[0024] Furthermore, the flexible patch 62 has a bendable metal strip 8 embedded inside, and the metal strip 8 is arranged horizontally; when applying the flexible patch 62, the user can bend and adjust the metal strip 8 according to the actual shape of their own skin.

[0025] In this invention, when the user applies the flexible patch 62, they bend the horizontally arranged bendable metal strip 8 according to the actual shape of their skin, so that the flexible patch 62 fits the skin better. On the one hand, the bendability of the metal strip 8 improves the adaptability of the flexible patch 62 to different skin shapes, further enhancing the stability of the fit between the device and the skin and ensuring the accuracy of temperature detection. On the other hand, the horizontally arranged metal strip 8 can better adapt to the bending or undulation of the skin in the horizontal direction, such as the horizontal wrinkles caused by facial expressions on the forehead, ensuring that a good fit is maintained in various situations, while not affecting the flexibility of the patch in the vertical direction, achieving multiple benefits.

[0026] Furthermore, each outer wall of the housing 6 is provided with a flexible skirt 9, and an elastic pull rope 91 is embedded inside the flexible skirt 9. One end of the elastic pull rope 91 is fixed to the damping adjustment shaft 92. The damping adjustment shaft 92 is rotatably disposed in the mounting groove 61, and one end of the adjustment shaft extends out of the mounting groove 61 and is fixed with an adjustment knob 93.

[0027] In this invention, the flexible skirt 9 has multiple connection points evenly distributed inside, which are connected to the elastic pull cord 91. These connection points are tightly bonded to the flexible skirt 9 by injection molding or sewing. When the length of the elastic pull cord 91 changes, the tension of the pull cord acts on the connection points, thereby causing the flexible skirt 9 to deform. The flexible skirt 9 is made of silicone or polyurethane material with a certain degree of flexibility and elasticity, which can adaptively conform to the contour of the skin surface under tension. Whether it is a flat skin area or a curved area near a joint, it can fit tightly, reducing the gap between the device and the skin, improving the stability of the device, and ensuring that the temperature sensing module 1 maintains good contact with the skin, thus improving the accuracy of temperature detection. By rotating the adjustment knob 93, the damping adjustment shaft 92 is driven to rotate, thereby adjusting the tension of the elastic drawstring 91 and allowing the flexible skirt 9 to better conform to the skin. On the one hand, the adjustable elastic drawstring 91 can flexibly adjust the degree of contact between the flexible skirt 9 and the skin according to the user's needs and skin condition, enhancing the stability of the device. On the other hand, the design of the damping adjustment shaft 92 makes the adjustment process smoother and more precise, avoiding the impact of over- or under-adjustment on the use of the device. It can also prevent the adjustment knob 93 from rotating accidentally, ensuring the stability of the device during use, achieving multiple benefits.

[0028] Furthermore, the alarm module 4 includes an audible and visual alarm 41 and an adaptive adjustment component 42. The adaptive adjustment component 42 is used to adaptively adjust the position of the audible and visual alarm 41. The audible and visual alarm 41 is covered with a dust cover 43. The dust cover 43 initially closes the audible and visual alarm 41 and opens when the audible and visual alarm 41 is working.

[0029] In this invention, when the alarm module 4 receives a trigger signal from the microprocessor 3, the adaptive adjustment component 42 starts working, adjusting the position of the audible and visual alarm 41. At the same time, the audible and visual alarm 41 moves upward to open the dust cover 43 and emits an audible and visual alarm signal. When the temperature returns to normal, the audible and visual alarm 41 returns to its original position under the action of the relevant structure, and the dust cover 43 re-closes. On the one hand, the adaptive adjustment component 42 can adjust the audible and visual alarm 41 to the optimal warning position according to the device's wearing position and usage scenario, improving the propagation effect of the alarm signal and ensuring that the user can receive the alarm information in a timely manner. On the other hand, the dust cover 43 closes the audible and visual alarm 41 under normal conditions, effectively preventing dust and other impurities from entering, protecting the audible and visual alarm 41, and extending its service life. It can also automatically open when an alarm is triggered, without affecting the normal functioning of the alarm, achieving two goals at once.

[0030] Furthermore, the adjustment and adaptation assembly includes: a mounting base 421, a rotating shaft 422, a linkage rod 423, and a drive unit 424; The top of the housing 6 is provided with a boss, on which the mounting base 421 is fixedly installed. A vertical groove 425 is formed on the boss, and a drive unit 424 is provided at the bottom of the vertical groove 425. The drive unit 424 is connected to the rotating shaft 422. The linkage rod 423 is fixed in the vertical groove. The mounting base 421 is adapted to the vertical groove 425. The mounting base 421 is sleeved on the rotating shaft 422 and is also slidably sleeved on the linkage rod 423. A spiral groove is formed on the outer surface of the rotating shaft 422. The rotating shaft 422 and the mounting base 421 are connected by a spiral drive. The audible and visual alarm 41 is installed on the mounting base 421. One end of the dust cover 43 is hinged to the mounting base 421 by a torsion spring. The drive unit 424 is electrically connected to the power supply module 5.

[0031] In this invention, when an alarm is triggered, the drive unit 424 activates a micro motor, which drives the rotating shaft 422 to rotate. Since the rotating shaft 422 and the mounting base 421 are connected by a helical transmission, the rotation of the rotating shaft 422 causes the mounting base 421 to move vertically. During the movement of the mounting base 421, the audible and visual alarm 41 is moved to a suitable position, and at the same time, the audible and visual alarm 41 pushes open the dust cover 43 to sound the alarm. On the one hand, through the helical transmission and linkage structure, the position of the audible and visual alarm 41 can be precisely adjusted, making it better adaptable to different usage scenarios and improving the alarm effect. On the other hand, the structure is compact, and while realizing the position adjustment of the audible and visual alarm 41 and the automatic opening and closing of the dust cover 43, it occupies little space, does not affect the normal operation of other parts of the equipment, and can also ensure the overall stability of the equipment, achieving multiple benefits. In addition to the above functions, it can also be used, for example, during heat therapy. It can be applied to the appropriate location based on the need for heat therapy to monitor local temperature changes. If the temperature exceeds the set limit, an alarm will sound, allowing for timely intervention to prevent burns. In some other embodiments, it can be configured as a square housing 500, with a mounting frame 501 fixed around its perimeter. An adhesive patch 502 is fixedly mounted on the mounting frame 501. A temperature measuring area 503 is located in the center of the bottom surface of the housing 500. An alarm can also be installed on the square housing 500 and connected to an external receiver. When the alarm sounds, the receiver can display the specific temperature measuring instrument number that is triggering the alarm, based on a pre-set temperature measuring instrument number. LED screens can also be installed on both the square housing 500 and the external receiver to display the measured temperature.
