Description

Technical Field

[0001] This utility model relates to the field of physiotherapy equipment technology, and in particular to an infrared physiotherapy device. Background Technology

[0002] As a non-invasive treatment, the clinical efficacy of infrared therapy is closely related to the precision of temperature control. According to the industry standard "General Technical Requirements for Infrared Therapy Equipment" (YY 0306-2023), the equipment must clearly indicate the temperature control range (e.g., 35~45℃) and support graded adjustment (each grade temperature difference ≤2℃).

[0003] Current infrared physiotherapy equipment uses fixed temperature sensors, typically installed at preset locations on the top or side wall of the treatment chamber, achieving closed-loop temperature control through single-point or limited-point monitoring. However, static temperature monitoring presents significant technical bottlenecks in dynamic treatment scenarios: when the patient's position changes due to limb movement or clothing obstruction, a monitoring blind spot may form between the fixed sensor and the target area. Experimental data shows that such deviations can cause the actual local temperature to deviate from the set value, which not only affects therapeutic effects such as promoting synovial fluid metabolism and tissue repair, but may also cause secondary skin damage in temperature-sensitive conditions such as diabetic foot.

[0004] Clinical studies have further revealed the biologically specific requirements of temperature regulation. Taking human papillomavirus (HPV)-induced warts as an example, a team from the Chinese Academy of Engineering demonstrated through a randomized controlled trial that continuously maintaining the epidermal temperature in the target area at 44°C can specifically activate the Langerhans cell immune response and induce apoptosis in the virus-host cells. The study also indicated that highly keratinized areas such as the soles of the feet require a thermal compensation mechanism to raise the epidermal temperature to 46-48°C to achieve an equivalent therapeutic effect. However, the single-point monitoring mode of existing equipment cannot meet the needs of detecting temperature gradients in different regions.

[0005] Furthermore, on the one hand, there are differences in understanding among those skilled in the art; on the other hand, the applicant studied a large number of documents and patents when making this utility model, but due to space limitations, not all details and contents were listed in detail. However, this does not mean that this utility model does not have the features of these prior art. On the contrary, this utility model has all the features of the prior art, and the applicant reserves the right to add relevant prior art to the background art. Utility Model Content

[0006] In view of the shortcomings of the prior art, this application proposes an infrared physiotherapy device, which aims to solve one or more technical problems in the prior art.

[0007] This utility model relates to an infrared physiotherapy device, including a chamber and a temperature measuring component. The temperature measuring component includes a base fixed to the top of the chamber and a main rotating ball rotatably disposed in an axial through hole of the base. The bottom of the main rotating ball is connected to a temperature sensing head extending into the chamber, and the top is connected to a steering handle located outside the chamber. When the steering handle is driven to deflect, the main rotating ball rotates accordingly to change the detection direction of the temperature sensing head.

[0008] This novel infrared physiotherapy device utilizes a spherical mating structure between the main rotating bead and the base through-hole to create a three-dimensional motion constraint. This allows external control of the steering handle to synchronously drive the temperature sensor head for stepless angle adjustment within the chamber, maintaining thermal stability within the sealed space and achieving wide-area coverage of the temperature measurement path. The rigid, symmetrical connection design between the temperature sensor head and the steering handle allows operators to visually control the detection direction from outside the chamber, eliminating the mechanical interference of traditional built-in adjustment mechanisms on the physiotherapy environment. The spherical support system of the main rotating bead, through multi-point contact mechanical distribution, maintains the force balance of the transmission structure at any deflection angle, ensuring smooth steering and positioning accuracy, thereby improving the reliability of temperature detection and the safety of the physiotherapy process.

[0009] According to a preferred embodiment, an upper rotating bead ring and a lower rotating bead ring are radially installed within the through hole of the base, thus restricting the movement space of the main rotating bead between the two rotating bead rings. Each of the upper and lower rotating bead rings has a receiving groove, into which several auxiliary rotating beads are rotatably embedded, allowing the portions of the auxiliary rotating beads exposed outside the receiving grooves to form point-contact support with the spherical surface of the main rotating bead. The spatial constraint system formed by the double rotating bead rings simultaneously constrains the displacement freedom of the main rotating bead in both the axial and radial directions, allowing it to retain only pure rotational motion around the center of the sphere, making the temperature measurement process smoother. The rolling contact design between the auxiliary rotating beads and the main rotating bead transforms traditional sliding friction into rolling friction, significantly reducing the rotational torque requirement. Simultaneously, the multi-point contact load distribution ensures the stability of the main rotating bead's rotation axis at any steering angle, ensuring precise synchronization between the detection direction of the temperature sensor head and the steering handle's pointing direction, thereby improving the reliability of temperature monitoring during physiotherapy.

[0010] According to a preferred embodiment, when the main ball rotates, the auxiliary balls in the upper and lower ball rings roll within their corresponding receiving grooves. The free rolling of the auxiliary balls within these grooves decomposes the rotational motion of the main ball into multi-point contact rolling friction, significantly reducing the sliding friction resistance of traditional spherical pairs and improving the sensitivity of the control response.

[0011] According to a preferred embodiment, the top of the base is provided with a limiting boss surrounding the steering handle; wherein, when the steering handle deflects, the limiting boss contacts the surface of the steering handle through its top surface and / or inner sidewall, thereby limiting the maximum deflection angle of the steering handle in the corresponding deflection direction. The annular structure of the limiting boss and the dynamic cooperation with the steering handle form a rigid mechanical limit, and during deflection, the contact between the top surface and the inner sidewall triggers resistance feedback, ensuring smooth movement of the steering handle within a set angle range. This structure eliminates the risk of overload deflection through the principle of physical interference, protecting the main ball bearing transmission system from abnormal load impacts while maintaining the accurate correspondence between the detection direction of the temperature sensor head and the physiotherapy area.

[0012] According to a preferred embodiment, the top surface of the limiting boss is provided with a plurality of fluorescent indicator marks in a circumferential direction; the steering handle is aligned with the fluorescent indicator marks by its end to determine the detection direction of the temperature sensor head. The fluorescent marks distributed circumferentially on the limiting boss can form a visible orientation reference system, enabling the operator to quickly determine the current detection direction by visual alignment of the end of the steering handle, effectively eliminating the parallax error present in traditional mechanical pointers.

[0013] According to a preferred embodiment, a cover is provided between the steering handle and the limiting boss. The cover maintains the internal temperature of the compartment by sealing the gap between the compartment and the temperature measuring component. The cover uses a flexible sealing material to cover the connection area between the steering handle and the limiting boss. Through its deformation-fitting characteristics, it dynamically compensates for mechanical displacement gaps during operation, forming a continuous and closed heat insulation barrier, which significantly reduces the loss of heat radiation from the compartment to the temperature measuring component area through the gap.

[0014] According to a preferred embodiment, the main rotating bead has a wire inside. One end of the wire is connected to a temperature sensing head, and the other end passes through the hollow tube of the steering handle and forms an electrical connection with the temperature measuring host on the top of the compartment. The wire inside the main rotating bead bends synchronously with its rotation, forming a smooth bending path through the guiding constraint of the hollow tube of the steering handle. This avoids kinking or local stress concentration in the wire during frequent angle adjustments, ensuring stable transmission of electrical signals during dynamic adjustment.

[0015] According to a preferred embodiment, multiple sets of heaters are arranged along the long axis of the cabin interior wall, and each heater is electrically connected to a control panel disposed on the exterior wall of the cabin. The strip heaters, equidistantly arranged along the long axis of the cabin interior wall, form a continuous radiating surface. Their axial extension characteristics make the infrared thermal radiation coverage area match the height of the human body's long axis, and the axial symmetry of the heat conduction path significantly reduces the local temperature difference.

[0016] According to a preferred embodiment, the heater is a radiant panel attached to the inner wall of the cabin. The close fit between the radiant panel and the curved surface of the cabin allows far-infrared rays to radiate uniformly along the normal direction of the cabin, forming a wraparound heat field distribution, effectively eliminating the temperature gradient differences caused by traditional point heat sources.

[0017] According to a preferred embodiment, a double-layered shielding curtain is provided at the cabin opening. The inner layer of the double-layered shielding curtain is made of flexible heat-insulating fabric, and the outer layer is made of elastic silicone sealing layer. The inner flexible heat-insulating fabric forms a dense heat-insulating barrier through multiple interwoven fibers. Its low thermal conductivity effectively blocks the outward diffusion of heat radiation from inside the cabin. Combined with the deformation-adhesive capability of the outer elastic silicone sealing layer, a continuous annular sealing band is formed when the cabin opening is closed, significantly inhibiting the infiltration of external cold air. The high resilience of the silicone layer allows it to adapt to the limb contours of patients of different body types, ensuring a seal while avoiding pressure discomfort at the contact points.

Detailed Implementation

[0020] The present invention will now be described in detail with reference to the accompanying drawings.

[0021] This embodiment relates to an infrared physiotherapy device, such as... Figure 1As shown, the device mainly consists of two parts: a chamber 100 and a temperature measuring component 200. The chamber 100 forms the main frame of the infrared physiotherapy device, employing an arched shell structure design to create a stable far-infrared radiation space inside. The chamber 100 has detachable curtains 120 at both axial openings, forming a relatively sealed physiotherapy environment through the closed curtain structure to ensure the therapeutic effect. The temperature measuring component 200 is located on the top of the chamber 100, and its temperature sensing head 230 extends into the chamber 100 via a mechanical connection. The temperature measuring component 200 is also equipped with an external steering handle 240 connected to the tail of the temperature sensing head 230. Operators can adjust the position of the temperature sensing head 230 from outside the chamber 100 by rotating the handle 240, thereby enabling real-time monitoring of the temperature in different areas of the chamber without interfering with the physiotherapy process.

[0022] like Figure 3 As shown, the temperature measuring assembly 200 includes a base 210, a main rotating ball 220, a temperature sensing head 230, and a steering handle 240. These components cooperate to form a mechanical transmission system that allows for adjustable temperature measurement direction. The temperature measuring assembly 200 is fixed to the outer center of the top of the chamber 100 via the base 210. The base 210 is a stainless steel cylindrical structure, with an axial through-hole forming the rotating chamber of the main rotating ball 220. The diameter of this through-hole forms a clearance fit with the stainless steel sphere of the main rotating ball 220, ensuring both free rotation of the main rotating ball 220 and maintaining structural stability. The center of the main rotating ball 220 coincides with the axis of the base 210. Its bottom can be connected to the temperature sensing head 230 using any connection method known to those skilled in the art, such as threaded connection, welding, bonding, or snap-fit. The top is connected to the cylindrical steering handle 240 using the same process, forming a mechanical transmission structure that links the inside and outside of the chamber 100. Figure 4 As shown, this design ensures that the temperature sensor head 230 is always located inside the physiotherapy space of the chamber 100, while the steering handle 240 is entirely located in the operating area outside the chamber 100. Preferably, the temperature sensor head 230 and the steering handle 240 are symmetrically distributed at 180° along the axis of the main rotating ball 220, allowing the operator to precisely control the orientation of the end of the temperature sensor head 230 by rotating the steering handle 240. A non-slip rubber grip can also be provided at the top of the steering handle 240 to further enhance operational stability.

[0023] like Figure 3 and Figure 5As shown, the base 210 employs a double-ring support structure, restricting the movement space of the main rotating bead 220 between the upper rotating bead ring 201 and the lower rotating bead ring 203, ensuring that the position of the center of the main rotating bead 220 remains constant during rotation. The upper rotating bead ring 201 is located 0.5~1.5cm below the top opening of the base and can be machined into a trapezoidal ring structure, fixed to the vertical inner wall of the base 210 by adhesive or bolts. The inner side of the upper rotating bead ring 201 has an upper receiving groove 202 of a certain depth. The bottom of the upper receiving groove 202 is semi-circular, wherein the central axis of the semi-circular bottom profile forms an acute angle with the horizontal reference plane. Figure 6 As shown, several auxiliary rotating beads 205 are equally spaced and embedded in the upper receiving groove 202. The diameter of each auxiliary rotating bead 205 matches the width of the groove, and the portion of its top protruding from the upper receiving groove 202 forms point contact with the upper hemisphere surface of the main rotating bead 220. (Continue referring to...) Figure 3 and Figure 5 A lower rotating bead ring 203 is symmetrically arranged inside the base 210 at a distance of 0.5 to 1.5 cm from the bottom opening. Its structure is mirror-symmetrical to the upper rotating bead ring 201. The inclination direction of the lower receiving groove 204 is opposite to that of the upper receiving groove 202, but the angle is the same. The arrangement of the two rotating bead rings ensures that within the active space of the main rotating bead 220 formed between them, several auxiliary rotating beads 205 are evenly distributed to form a support system for the main rotating bead 220. This ensures that the main rotating bead 220 can obtain stable support from the contact points of multiple auxiliary rotating beads 205 when rotating in any direction, achieving stable rotational motion without directional constraints.

[0024] like Figure 2 As shown, the base 210 has a limiting boss 250 on its top to limit the deflection angle of the steering handle 240. The limiting boss 250 is an annular structure surrounding the base 210, and its inner diameter is larger than the outer diameter of the steering handle 240, ensuring that the steering handle 240 has sufficient room to deflect.

[0025] Figure 5The angle α shown is the deflection angle of the steering handle 240, which indicates the degree to which the steering handle 240 deviates from the vertical axis of the main ball bearing 220. As the steering handle 240 deflects in a certain direction, the angle α gradually increases. When the edge of the steering handle 240 touches the junction of the top surface and the inner wall of the limiting boss 250, the deflection of the steering handle 240 in that direction reaches its limit. This means that the limiting boss 250 determines the maximum deflection angle of the steering handle 240. Obviously, increasing the height of the limiting boss 250 or increasing the outer diameter of the steering handle 240 will reduce the range of deflectable angles of the steering handle 240; and vice versa. Since the detection direction of the temperature sensor head 230 is consistent with the axis of the steering handle 240, the limitation of the steering handle 240's deflection angle by the limiting boss 250 also limits the detection area of ​​the temperature sensor head 230. Therefore, the larger the included angle α, the greater the degree of deflection of the steering handle 240, and the wider the detection area that the temperature sensor head 230 can cover. This design ensures the accuracy and flexibility of equipment operation and temperature detection.

[0026] like Figure 2 As shown, the upper surface of the limiting boss 250 is provided with several (8 or 12) indicator marks 251 distributed at equal angles, and each indicator mark 251 has a fluorescent digital symbol embedded in its center. The arrangement of the indicator marks 251 is designed such that when the operator aligns the end of the steering handle 240 with a certain mark, the detection direction of the temperature sensor head 230 points precisely to a specific preset detection point on the user's treatment area. When the end of the steering handle 240 is aligned with all the indicator marks 251 in succession, the detection direction of the temperature sensor head 230 can fully cover all treatment areas of the user's body, thereby ensuring comprehensive temperature measurement.

[0027] like Figure 2 As shown, a cover 241 is provided between the steering handle 240 and the limiting boss 250. It can be made of flexible heat-insulating fabric to seal the gap between the compartment 100 and the temperature measuring component 200, which is conducive to maintaining the temperature inside the compartment 100.

[0028] Preferably, the shielding curtains 120 installed at the axial openings of the chamber 100 can adopt a double-layer design. The inner layer is an opaque curtain made of flexible heat-insulating material, and the outer layer is a sealing layer made of elastic silicone material. The two are bonded together as a whole through a hot-pressing process. When the user inserts the area to be treated into the chamber 100, the silicone sealing layer of the shielding curtain 120 can fit tightly against the skin surface, preventing internal heat loss and avoiding the entry of external air that may affect temperature stability.

[0029] like Figure 1As shown, the outer surface of the chamber 100 is covered with a heat-insulating buffer layer and has a reserved mounting groove for integrating the control panel 130. The control panel 130 is located on the top of the outer wall of the chamber 100 for easy observation and operation by the user while standing. The internal circuitry is connected to the power module at the rear of the chamber 100 via a waterproof connector. The temperature measuring component 200 can be installed on the surface of the chamber 100, preferably at the top of the chamber 100. It is used to measure the temperature of the user's skin surface during physiotherapy to ensure that the skin temperature reaches the standard.

[0030] like Figure 1 As shown, multiple sets of strip heaters 110 are distributed on the inner wall of the cabin 100. Each set of heaters 110 extends along the long axis of the cabin 100, and both ends are fixed to the reserved slots of the longitudinal reinforcing ribs of the cabin 100 by rivets. The core heating element of the heater 110 is a spiral carbon fiber woven strip, wrapped with mica sheet as an insulation layer, and covered with a metal mesh protective cover on the outermost layer. Preferably, the heater 110 can be made of electrically heating materials, such as heating wire or carbon fiber heating wire. More preferably, the heater 110 can also be a heating layer attached to the inner wall of the cabin 100, such as a radiant plate. The power supply line of the heater 110 runs along the wire groove pre-embedded in the inner wall of the cabin 100, and finally converges to the junction box at the rear of the cabin 100 and connects to the temperature adjustment circuit of the control panel 130, so that the user can turn the far-infrared heating tube on and off and adjust the irradiation temperature by operating the control panel 130. The chamber 100, the far-infrared heating tube, and the control panel 130 can all be made of existing technologies, such as the foldable far-infrared therapy chamber disclosed in CN219251431U, in which the chamber body, heating layer, and temperature controller can realize the functions of the corresponding components mentioned above in this embodiment.

[0031] like Figure 4 , Figure 5 As shown, the temperature sensor head 230 is connected to the temperature measuring host 232 via internal wiring. The wire 231 extends from the waterproof interface at the tail of the sensor head, then enters the hollow cavity at the center of the main rotating ball 220 along a pre-set groove at the bottom of the ball. The wire 231 passes through a spring-shaped spiral sleeve within the cavity, exits through a hole at the top of the main rotating ball 220, and enters the hollow aluminum alloy tube in the steering handle 240. The temperature measuring host 232 is installed in an independent compartment on the right side of the top of the chamber 100. Its internal circuit board is connected to the temperature sensor head 230 via a shielded cable. When the main rotating ball 220 drives the temperature sensor head 230 to rotate, the temperature measuring host 232 displays the temperature value of the current detection point in real time. The temperature sensor head 230 preferably uses a non-contact infrared temperature measuring device, and the temperature measuring host 232 uses a medical-grade temperature monitoring terminal with signal processing capabilities.

[0032] Preferably, in addition to basic temperature measurement functions, the temperature measuring host 232 can also integrate an alarm module and a display duration module as part of its functional expansion scheme to enhance the practicality of the device. The alarm module generates an alarm signal when the ambient temperature exceeds a preset threshold range. This module includes, but is not limited to, audible and visual alarm devices, such as buzzers and / or light-emitting diodes (LEDs), which are driven by electrical signals to provide audible and / or visual cues, thereby promptly notifying the user to take appropriate measures. The alarm module is based on a common medical device temperature monitoring architecture in the prior art, specifically employing a mature threshold alarm technology solution in the medical field. The module includes audible and visual alarm components standard in medical monitoring equipment, such as an audio alarm unit similar to that of an infusion pump alarm and a multi-color LED indicator array, achieving the alarm function through a signal driving circuit commonly used in medical electronic devices in the prior art. The display duration module can also adopt a timing display technology solution commonly used in medical devices, with specific implementations referencing mature designs in existing medical monitoring equipment. The display unit uses a digital tube component similar to that of the infusion pump treatment time display module, and its hardware architecture directly matches the multi-parameter display system of operating room monitors. The timing unit adopts conventional and precise timing technology in the medical field, such as the timing scheme of the ventilator ventilation time recording module, and is implemented through medical electronic timing circuits known in the field. Its timing accuracy meets the monitoring standards of medical equipment for treatment duration.

[0033] It should be noted that the above specific embodiments are exemplary. Those skilled in the art can devise various solutions inspired by the disclosure of this utility model, and these solutions all fall within the scope of this utility model and its protection scope.

Throughout the text, features introduced by "preferred" are merely optional and should not be construed as mandatory. Therefore, the applicant reserves the right to abandon or delete relevant preferred features at any time.
