Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical instrument equipment, in particular to a device for assisting human eyes to judge the position of infrared light. BACKGROUND

[0002] Light therapy is a method of preventing and treating diseases by using artificial visible light emitters or natural visible light emitters, and is one of the commonly used methods of physical therapy. Infrared rays have low frequency and energy, and can only penetrate the gap between atoms and molecules, but cannot penetrate the inside of atoms and molecules. Through infrared radiation, the vibration of atoms and molecules is accelerated, the spacing is enlarged, that is, the thermal motion energy is increased, and the substance will undergo physical effects such as warming, melting, and vaporization. The structure of the atoms and molecules of the substance does not change. These characteristics of infrared rays make infrared therapy a safe and diverse therapy method.

[0003] However, since infrared rays belong to invisible light, it is difficult for doctors to determine whether the infrared rays are accurately irradiated to the affected area. Generally, the light path of the infrared rays is set in advance, and then the position of the patient is adjusted to achieve this. However, not all patients have experience with infrared therapy, which requires the patient to repeatedly adjust their own position, which can cause a poor experience for the patient. SUMMARY

[0004] In view of the deficiencies of the prior art, the present application provides a device for assisting human eyes to judge the position of infrared light, which comprises a shell, a base is arranged inside the shell, and an outlight groove and a light supplementing groove are formed in the base; the outlight groove is arranged along the front-rear direction, the forward opening of the outlight groove penetrates the base and the shell, and the opening of the light supplementing groove is in communication with the side of the outlight groove;

[0005] An infrared light emitter is arranged at the rear end of the outlight groove, a visible light emitter is arranged at the lower end of the light supplementing groove, and a light path adjuster is arranged at the opening position of the light supplementing groove in the outlight groove; the light path adjuster comprises a mirror and a mounting column; one end of the mounting column is connected with the groove wall of the outlight groove, the other end of the mounting column is formed with an inclined surface, the inclined surface is gradually inclined upward from the rear to the front, and the back of the mirror is arranged in close contact with the inclined surface of the mounting column.

[0006] In this way, the visible light is guided into the outlight groove where the infrared light emitter is located by the light path adjuster, so that the infrared light and the visible light are emitted outward along the outlet of the outlight groove. Therefore, the light path of the infrared light can be judged by the light path of the visible light, and the infrared rays can be more intuitively irradiated to the affected area to achieve therapy.

[0007] As an optimization, the light supplementing groove is located below the outlight groove and is arranged along the up-down direction; the included angle between the inclined surface and the axis of the mounting column is 45°.

[0008] As an optimization, the slope of the mounting column is opposite to the opening of the light supplement groove, and the emitting end of the visible light emitter is directed towards the direction of the reflector, so that the visible light emitted by the visible light emitter can be emitted along the light supplement groove to the reflector.

[0009] In this way, after the visible light enters the light emitting groove from the light supplement groove, the same effect as the direction of the infrared light can be achieved more accurately.

[0010] As an optimization, a lampshade structure is mounted on the housing at a position corresponding to the opening of the light emitting groove; a plurality of light guide grooves extending along the axial direction are formed in the front end face of the lampshade structure near the end face edge; and a light transmission strip capable of covering all the light guide grooves is arranged at the end of the lampshade structure away from the housing.

[0011] In this way, the visible light is emitted from the light transmission part of the end face edge of the lampshade structure, and will not directly shine into the human eye to cause glare.

[0012] As an optimization, the visible light emitter is mounted on one side of the lampshade structure, and the visible light emitter includes an integrated circuit board and a lamp bead mounted on the integrated circuit board; a light transmission plate is arranged at the opening of the light supplement groove, and a light collection groove is formed in the light transmission plate, the light collection groove is shaped like a cone, and the wide end of the light collection groove is directed towards the lamp bead.

[0013] The applicant found that, due to the low visible light guide efficiency inside the base and the inclined arrangement of the reflector, the part close to the visible light emitter inside the base has high brightness, and the part far from the visible light emitter has low brightness, thereby causing the brightness of the visible light emitted by the lampshade structure to be uneven, which easily causes visual dizziness. In order to solve this problem, in the present application, the light collection groove is arranged in a conical structure, and the lamp bead is aligned with the wide end of the light collection groove, so that the light collection groove can completely surround the light emitted by the lamp bead, thereby absorbing most of the light energy of the lamp bead, and further greatly reducing the overflow of light energy, improving the light guide efficiency at the light transmission plate, and realizing the uniform brightness of the visible light.

[0014] As an optimization, the lampshade structure includes a tightening part integrally connected to the upper and lower sides of the rear part, respectively, the tightening part is arranged in a shape gradually tightened inward from front to rear, and the tightening part is also arranged in a trend gradually shortened from the narrow end to the wide end; one end of the light guide groove penetrates the rear end face of the tightening part, and the other end of the light guide groove penetrates the front end face of the lampshade structure.

[0015] In this way, the light troughs will lead the absorbed light energy from the upper and lower sides to the whole lampshade structure through the tightening parts, respectively. Since the two tightening parts are arranged on the two sides of the lampshade structure, the brightness of the whole lampshade structure is ensured to be uniform. In addition, in the present application, the closer the distance between the lampshade structure and the visible light emitter, the smaller the cross-sectional area of the lampshade structure. In this way, the light energy consumed by the lampshade structure is reduced, thereby improving the uniformity of the brightness of the lampshade structure.

[0016] As an optimization, the size of the opening aperture of the light guide groove located at the rear of the tightening part is greater than the size of the opening aperture of the light guide groove located at the front.

[0017] In this way, the aperture of the light guide groove is larger at the place close to the lampshade structure, and the light energy transmitted through the light guide groove at this place is also more, which compensates for the disadvantage of the consumption of light energy due to the electric conduction of the lampshade structure itself, thereby improving the brightness uniformity of the lampshade structure.

[0030] The following embodiments of the technical solution of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0031] Example: Figures 1-5 As shown, a device for assisting the human eye in determining the position of infrared light includes a housing 1, a base 2 disposed within the housing 1, and a light-emitting slot 21 and a fill-light slot 22 defined within the base 2. The light-emitting slot 21 is disposed in a front-to-back direction, with its forward opening extending through the base 2 and the housing 1. The fill-light slot 22 is connected to a side of the light-emitting slot 21.

[0032] An infrared light emitter 3 is disposed at the rear end of the light exit slot 21, a visible light emitter 4 is disposed at the lower end of the fill light slot 22, and an optical path adjuster 5 is disposed within the light exit slot 21 at a position corresponding to the opening of the fill light slot 22. The optical path adjuster 5 comprises a reflector 51 and a mounting post 52; one end of the mounting post 52 is connected to the wall of the light exit slot 21, and the other end of the mounting post 52 is formed into an inclined surface that gradually increases in an upward direction from the back to the front. The back of the reflector 51 is disposed in contact with the inclined surface of the mounting post 52.

[0033] In this way, the present application guides the visible light into the light output slot where the infrared light emitter is located through the optical path adjuster, so that the infrared light and visible light are emitted outward along the outlet of the light output slot. Therefore, the optical path of the infrared light can be judged with the help of the optical path of the visible light, and then the infrared light can be more intuitively irradiated to the affected area to achieve physical therapy.

[0034] Specifically, the fill light slot 22 is located below the light exit slot 21 and is arranged in the vertical direction. The angle between the inclined surface and the axis of the mounting post 52 is 45°. The inclined surface of the mounting post 52 is aligned with the opening of the fill light slot 22. The emitting end of the visible light emitter 4 is oriented toward the reflector 51, allowing the visible light emitted by the visible light emitter 4 to travel along the fill light slot 22 and onto the reflector 51.

[0035] In this way, after the visible light enters the light output slot from the fill light slot, it can more accurately achieve the same effect as the direction of the infrared light.

[0036] Specifically, the lampshade structure 6 made of metal material is installed on the shell 1 at the position corresponding to the opening of the light emitting groove 21. The front end face of the lampshade structure 6 is provided with a plurality of light guide grooves 62 extending along the axial direction near the end face edge thereof. The end of the lampshade structure 6 away from the shell 1 is provided with a light transmission strip 61 capable of covering all the light guide grooves 62.

[0037] In this way, the visible light is emitted from the light transmission part of the end face edge of the lampshade structure, and cannot directly irradiate the human eye to cause glare.

[0038] Specifically, the visible light emitter 4 is installed on one side of the lampshade structure 6, and the visible light emitter 4 comprises an integrated circuit board 41 and a lamp bead 42 installed on the integrated circuit board 41. A light transmission plate 7 is arranged at the opening of the light supplement groove 22, and the light transmission plate 7 is provided with a light collecting groove 71 shaped like a cone, and the wide end of the light collecting groove 71 faces the lamp bead 42.

[0039] The applicant finds that, due to the low visible light guide efficiency inside the base and the inclined arrangement of the reflector, the part close to the visible light emitter is high in brightness, and the part far from the visible light emitter is low in brightness, thereby causing the brightness of the visible light emitted by the lampshade structure to be uneven, which is easy to cause the adverse effect of visual dizziness. In order to solve this problem, in the present application, the light collecting groove is arranged in a conical structure, and the lamp bead is aligned with the wide end of the light collecting groove, so that the light collecting groove can completely surround the light emitted by the lamp bead, thereby absorbing most of the light energy of the lamp bead, and further greatly reducing the overflow of light energy, improving the light guide efficiency at the light transmission plate, and realizing the uniform brightness of the visible light.

[0040] Specifically, the lampshade structure 6 comprises a tightening part 63 integrally connected on the upper and lower sides of the rear part thereof, respectively, and the tightening part 63 is arranged in a shape gradually tightening inward from front to rear, and the tightening part 63 is also arranged in a trend gradually shortening from the narrow end to the wide end. One end of the light guide groove 62 penetrates the rear end face of the tightening part 63, and the other end of the light guide groove 62 penetrates the front end face of the lampshade structure 6.

[0041] In this way, the light energy absorbed by the light collecting groove is guided out to the entire lampshade structure through the tightening parts on the upper and lower sides, respectively, and since the two tightening parts are distributed on the two sides of the lampshade structure, the brightness of the entire lampshade structure is ensured to be consistent; in addition, in the present application, the closer the distance between the lampshade structure and the visible light emitter, the smaller the cross-sectional area of the lampshade structure, so that the light energy consumed by the lampshade structure is reduced, thereby improving the uniformity of the brightness of the lampshade structure.

[0042] Specifically, the size of the opening caliber of the light guide groove 62 located at the rear relative to the rear end face of the tightening part 63 is greater than the size of the opening caliber of the light guide groove 62 located at the front.

[0043] In this way, the diameter of the light guide groove is larger near the lampshade structure, and the light energy transmitted through the light guide groove is also more, which compensates for the light energy consumed due to the conductivity of the lampshade structure itself, thereby improving the brightness uniformity of the lampshade structure.

[0044] The above examples are only used to illustrate the technical solutions of the present application, but not to limit it; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that the technical solutions recorded in the foregoing examples can still be modified, or some or all of the technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should be covered in the scope of the claims and the specification of the present application.
