Description

Technical Field

[0001] The invention belongs to the technical field of medical care and relates to an infrared parallel light beam physiotherapy device. Background Art

[0002] Known infrared therapy devices, due to their non-portability, invasiveness, and relative safety, are widely used in therapeutic areas such as soft tissue injury recovery, musculoskeletal pain, blood circulation promotion, wound healing, cosmetic procedures, and sleep improvement. These devices include lamps, pads, belts, knee pads, wrist guards, and more. Infrared therapy lamps typically focus infrared radiation from a source through a lampshade or reflector, then reflect it toward the treatment area. The reflected and direct infrared radiation diffuses in a fan-shaped pattern. While this diffused infrared radiation has little effect on adults, it can be harmful to infants and young children, as their eyes are more fragile and their lenses are more transparent than those of adults. This inability to effectively filter out infrared radiation can easily cause retinal damage. Summary of the Invention

[0003] The present invention aims to address the above-mentioned deficiencies of known infrared therapy lamps and devices and to provide an infrared parallel beam therapy device.

[0004] The technical method adopted to realize the above invention is as follows: An infrared parallel beam therapy device comprises: an infrared parallel beam radiator, a control device, a power supply, a bracket, and a base, wherein the infrared parallel beam radiator consists of a radiation source, a radiation source base, a reflector, a convex lens, a light guide tube, and a support; the radiation source is fixed to the inner cavity of the reflector by the radiation source base, the incident port of the light guide tube is connected to the opening of the reflector and then installed on the support, and a lens group is arranged in the light guide tube; the convex lens is fixed to the front end of the radiation source so that the focal points of the reflector and the convex lens coincide with the luminous center of the radiation source, maintaining the relative position unchanged; the radiator is fixed to the upper end of the bracket, and the angle can be adjusted arbitrarily; the other end of the bracket is fixed to the base, and the distance and position between the upper end of the bracket and the base are adjustable; the working power supply of the radiator is connected to the control device and the power supply in sequence through a connecting line.

[0005] Furthermore, the radiation source is composed of a plurality of light sources, and the operation of the plurality of light sources can be controlled individually or in groups by the control device; each light source is composed of at least one light point.

[0006] Furthermore, the cross section of the reflective surface of the reflector is parabolic or semicircular.

[0007] Furthermore, the shape of the inner hole of the light beam emitting end of the light guide is circular, oblong, or rectangular.

[0008] Furthermore, the cross-sectional shape of the light guide is cylindrical, or transitions from a short cylinder to a long cylinder, or transitions from a truncated cone to a column, or transitions from a circular cross-section to an oblong cross-section, or transitions from a circular cross-section to a rectangular cross-section; in the transitional light guide, after the incident light beam enters the light guide, it is deformed by the lens group arranged in the light guide, thereby converting the circular parallel light beam into an oblong light beam, or converting the circular parallel light beam into a rectangular parallel light beam.

[0009] Furthermore, the outer wall of the light guide tube is provided with a heat dissipation structure or a heat insulation layer.

[0010] Furthermore, the cross-sectional shape of the parallel beam emitted outward by the parallel beam radiator is circular, oblong, or rectangular.

[0011] Furthermore, the lens group is composed of any one or more of a spherical plano-convex lens, a double hemispherical convex lens, an aspherical plano-convex lens, a plano-convex cylindrical lens, or a double convex cylindrical lens.

[0012] In the present invention, the vast majority of infrared rays are emitted outward in the form of parallel light beams through a light-guiding tube; when the radiation source is powered on, the infrared rays emitted forward by the radiation source are converted into parallel light beams by a convex lens and emitted outward, and the infrared rays emitted backward are directly emitted outward in the form of parallel light beams from outside the boundary of the convex lens through a reflective cover. The combination of the two ensures that the vast majority of infrared rays emitted by the radiation source are emitted outward in the form of beams composed of parallel light beams, thereby avoiding the scattering of infrared rays and achieving the purpose of the invention.

[0013] When using an infrared parallel beam therapy device, the infrared spectrum can be precisely controlled by voltage or current, and the heat intensity can be achieved by controlling the number of working light spots through a multi-light point radiation source. When in use, the infrared beam can be used to irradiate the therapy area, and the distance between the light guide tube and the human skin is limited to a limit where the accumulated temperature does not cause heat damage to the skin.

[0014] This infrared parallel beam physiotherapy device has the functions of relieving pain, promoting blood circulation, and repairing wounds. It is mainly used for auxiliary physiotherapy of sprains, local inflammation, and promoting wound healing in infants and young children.

[0015] The beneficial effects of the present invention are as follows: the infrared parallel beam therapy device changes the problem of infrared scattering in known infrared therapy lamp products, avoiding the damage to non-therapy parts caused by scattered infrared rays when infants and young children use infrared therapy, especially the eyes of infants and young children; at the same time, the use of a parallel beam makes the radiation source energy be utilized to the maximum extent, thereby improving the utilization rate of the radiation source energy.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] In the present invention, the radiator 9 of the infrared parallel beam therapy device is composed of a radiation source 1, a radiation source base 2, a reflector 3, a convex lens 4, a light guide 5, and a support 6; the parallel light beam emitted by the radiator 9 is composed of parallel light directly emitted from the front of the radiation source 1, converted into parallel light by the convex lens 4, and reflected by the reflector 3; in order to make the infrared light reflected by the reflector 3 be emitted in parallel, the reflector 3 adopts a parabolic configuration, and its focus coincides with the center point of the radiation source 1 and the focus of the convex lens 4; in order to avoid the diffusion of infrared light caused by refraction in the air, a light guide 5 is added to the radiator 9, so that all pipelines are emitted outward through the light guide, thereby controlling the diffusion of infrared light to the maximum extent; at the same time, adding a filter 7 at the emission port of the light guide 5 can filter out non-infrared light, and can also effectively protect the light guide 5 from being polluted by dust, moisture, etc. in the air.

[0019] In order to meet the different requirements for the cross-sectional shape of the beam in infrared therapy, the radiation source 1 can be a circular combination of one or more points, or a linear light source, and can be matched with a corresponding reflector 3 and a convex lens 4, and directly emit a parallel beam with a circular, oblong, or rectangular cross-sectional shape outward through the light guide 5; In order to achieve the outward radiation of light beams with various cross-sectional shapes from one radiation source, the cross-sectional shape of the light guide 5 is cylindrical, or transitioning from a short cylinder to a long cylinder, or transitioning from a truncated cone to a column, or transitioning from a circular cross-sectional shape to an oblong cross-sectional shape, or transitioning from a circular cross-sectional shape to a rectangular cross-sectional shape; Furthermore, in the transitional light guide, the incident light beam enters the light guide and is deformed by the lens group 8 provided in the light guide, thereby transforming the circular parallel beam into a long hole circular beam, or transforming the circular parallel beam into a rectangular parallel beam.

[0020] In order to achieve different physical therapy effects, in a light source composed of multiple light points, the operation of each light source can be controlled separately or in groups to meet the requirements of the output power of the radiation source 1 in different physical treatments; The infrared parallel beam physiotherapy device described in the present invention is composed of a radiator 9, a control device 11, a power supply 14, a bracket 10, and a base 12. The working power of the radiator 9 is transmitted through a connecting line 13. The power supply 14 can be powered by AC power, DC power, or battery. The radiator 9 is the core component of the infrared parallel beam physiotherapy device; the control device 11 has power control and time control functions, and can also realize regulation and control of the infrared spectrum through voltage or current regulation control; the bracket 10 is adjustable and can also be replaced by a metal or plastic hose. In the floor-standing physiotherapy device, a height-adjustable support rod can also be added to meet different usage requirements.

[0021] When using this physiotherapy device, the emission window of the light guide 5 is required to maintain a certain distance from the human skin to avoid skin burns. During use, the position of the radiator 9 is fixed by the bracket 10 and the base 12 and can be adjusted at multiple angles. The bracket 10 and the base 12 can be either desktop or floor-standing. Example 1

[0022] See also Figure 1 , Figure 1 The longitudinal section structure and working principle diagram of a radiator in the present invention is shown in FIG. The radiator is composed of a radiation source 1, a radiation source base 2, a reflector 3, a convex lens 4, a light guide 5 and a support 6.

[0023] In this radiator, the radiation source 1 uses an infrared tungsten filament lamp bead, and the reflector 3 adopts a parabolic configuration. In the structure, the focus of the reflector 3, the center of light emission of the radiation source 1, and the focus of the convex lens 4 coincide with each other. Moreover, the reflector 3, the center of light emission of the radiation source 1, the convex lens 4, and the light guide 5 are all located on the same center line and their relative positions remain unchanged. The radiation source 1 and the radiation source base 2 are fixed in the inner cavity of the reflector 3, and the incident port of the light guide 5 is connected to the opening of the reflector 3, and then mounted on the support 6. During operation, the infrared rays emitted by the radiator 9 are directed in any direction. Since the luminous center point of the radiation source 1 is at the focus of the reflector 3, except for the light that is not reflected by the opening part of the reflector 3, all the light directed to the reflector 3 will be reflected in parallel; the convex lens 4 is arranged in front of the radiator 9, and the focus coincides with the luminous center point of the radiation source 1. Its function is to convert all the light that is not reflected by the reflector 3 into parallel light, and then merge it with the parallel light reflected by the reflector 3 into a parallel light beam, which is emitted outward through the light guide 5, thereby realizing the parallel light beam emission of the radiator 9.

[0024] This radiator emits a circular infrared parallel beam. When used in physical therapy, the power is not high and the cross-sectional area of ​​the parallel beam is 1-20cm. 2 The range of the radiation source power is within 5 ~ 30W, which can basically meet all the requirements of use.

[0025] The radiator is suitable for various infrared parallel beam physiotherapy devices. Example 2

[0026] See also Figure 2 、 Figure 3 、 Figure 4 , Figure 2 This is a schematic diagram of the longitudinal cross-section structure and working principle of another radiator in the present invention. Figure 3 yes Figure 2 BB cross-section diagram, Figure 4 yes Figure 2 AA cross-section diagram.

[0027] This embodiment differs from the first embodiment in that the radiation source 1 is a linear emitting light source, the corresponding reflector 3 has only a parabolic inner cross-section, the corresponding convex lens 4 is semi-cylindrical, and the corresponding light guide 5 has a rectangular inner cross-section. This radiator emits a rectangular infrared parallel beam outward. The method of converting the infrared light emitted by the radiation source 1 into a parallel beam is the same as that in Example 1. The applicable scope of the radiator is the same as that in Example 1. Example 3

[0028] See also Figure 5 , Figure 5It is a schematic diagram of the longitudinal section working structure of a radiator with a light guide tube and a filter in the present invention.

[0029] The difference between this embodiment and embodiment 1 is that a filter 7 is added in front of the emission window of the light guide 5; the filter has the function of filtering out non-infrared light and can also effectively protect the light guide 5 from being polluted by dust, moisture and the like in the air.

[0030] The applicable scope of this embodiment is the same as that of embodiment 1. Example 4

[0031] See also Figure 6 、 Figure 7 , Figure 6 This is a schematic diagram of the longitudinal section of a working structure of a radiator for converting a cylindrical light beam into a rectangular or oblong light beam in the present invention. Figure 7 yes Figure 6 A-direction schematic diagram.

[0032] The difference between this embodiment and embodiment 1 is that the cross-sectional shape of the inner hole of the light guide 5 transitions from a circle to a rectangle, a circular reflector and its radiation source are used to radiate an infrared beam with a rectangular cross-section outward, and a lens group 8 is provided in the light guide 5; The lens group 8 consists of three lenses: the first circular semicircular convex lens from the left, the second is a binary lens, and the third is a rectangular inner arc concave lens; the parallel light beams from the reflector 3 and the convex lens 4 are converted into rectangular parallel light beams through the lens group 8; during operation, the focus of the first lens is on a straight line, and the parallel light beams from the reflector 3 and the convex lens 4 pass through the first lens and then enter the binary lens through the line, and the binary lens then converts the incident infrared light into a rectangular fan-shaped light beam, and finally the inner arc concave lens converts the rectangular fan-shaped light beam into a rectangular parallel light beam; this structure can realize the emission of two parallel light beams by replacing the light guide 5 with a set of light sources, meeting the needs of different physical therapy purposes.

[0033] The applicable scope of this embodiment is the same as that of embodiment 1. Example 5

[0034] See also Figure 8 , Figure 8 It is a schematic diagram of the longitudinal section working structure of a radiator for reducing a cylindrical light beam in the present invention.

[0035] The difference between this embodiment and embodiment 4 is that the inner hole of the light guide 5 is in a transitional shape from a short cylinder to a long cylinder, which reduces the cross-sectional area of ​​the light beam radiated outward by the circular reflector and its radiation source before radiating outward, thereby changing the circular parallel light beam from large to small; the lens group 8 arranged in the light guide 5 of this embodiment is also composed of three lenses: the first one from the left is a large circular convex lens, the second one is a small circular convex lens, and the third one is a filter 7. The circular parallel light beam is changed from large to small by the first and second convex lenses, and the filter 7 is mainly used to ensure the cleanliness of the surface of the second small circular convex lens and prevent dust pollution from affecting the lens performance.

[0036] The applicable scope of this embodiment is the same as that of embodiment 1. Example 6

[0037] See also Figure 9 , Figure 9 The figure is a schematic diagram of the working structure of an infrared parallel beam physiotherapy device in the present invention. The physiotherapy device is a desktop device, which is composed of a radiator 9, a control device 11, a power supply 14, a bracket 10 and a base 14.

[0038] In this embodiment, the radiator 9 is fixed to the upper end of the bracket 10 by bolts, and the angle can be adjusted at will. The other end of the bracket 10 is fixed to the base 14, and the distance and position between the upper end of the bracket 10 and the base 14 are adjustable. The working power of the radiator 9 is transmitted through the connecting line 13, and the control device 11 is arranged in the inner cavity of the base 14. In practical applications, the power supply 14 can be powered by an AC power supply, a DC power supply, or a battery. When powered by a battery, the battery can be installed in the inner cavity of the base 14. The control device 11 has power supply control and time control functions, and can also realize regulation and control of the infrared spectrum through voltage or current regulation control. Further, a control method combining panel control and wireless remote control can be adopted.

[0039] When using, first place the infrared parallel beam therapy device, adjust the radiator 9 so that the emission window of the radiator 9 is perpendicular to the part that needs therapy, and the distance between the window and the therapy part is greater than the distance for skin burns, generally not more than 15 cm, then set the time, and then turn on the power; the time and course of one therapy session shall be handled according to the product instructions.

[0040] This physiotherapy device has the functions of relieving pain, promoting blood circulation, and repairing trauma. It is mainly used for auxiliary physiotherapy of sprains, local inflammation, and promoting wound healing in infants and young children.

[0041] Finally, it should be pointed out that the above embodiments are only representative examples of the present application. Obviously, the present application is not limited to the above embodiments, and can have many combinations and variations. Any simple modification, equivalent change and modification made according to the technical method and embodiments of the present application should be considered to be within the protection scope of the present application.
