Description

Novel portable vitiligo detector

Technical Field

The utility model belongs to the technical field of portable inspection instrument, concretely relates to novel portable vitiligo detector.

Background

Vitiligo is a common acquired limited or generalized depigmentation disease of the skin, caused by the loss of melanocyte function of the skin, but the mechanism is not clear, and the disease can occur in various parts of the body. Vitiligo is a common skin disease affecting beauty, and the disease is characterized by local or generalized depigmentation and formation of white spots, and is easy to check and difficult to treat.

Currently, wood lamps are generally used to directly irradiate the affected part of the skin in a relatively dark room, and then the fluorescence pattern is observed to judge whether the skin is infected with fungi and the degree of infection. The wood lamp is also called wood lamp or filtered ultraviolet lamp, which obtains 320-400nm long-wave ultraviolet rays through a filter disc containing nickel hydride. As an auxiliary detection means for clinical application of dermatology, the detection method has wide range. However, most of the existing conventional wood lamps use a common bulb as an auxiliary light source and require an indoor power supply with an external voltage of 220V for power supply, so the existing wood lamps need to be used under specific environments and conditions, are heavy, generally inspect a large area on the skin during use, are inconvenient to quickly screen a small local area on the skin, and cannot be used conveniently and quickly.

Detailed Description

The following description of the embodiments of the present invention is provided to facilitate the understanding of the present invention by those skilled in the art, but it should be understood that the present invention is not limited to the scope of the embodiments, and various changes may be made apparent to those skilled in the art within the spirit and scope of the present invention as defined and defined by the appended claims.

As shown in fig. 1 and 3, the portable vitiligo detector comprises a handle 1 and a panel 2 which are in an integral structure. A plurality of ultraviolet LED lamps 17 (Light-Emitting diodes) are fixed on the surface of the panel 2 facing the skin of the patient, the ultraviolet LED lamps 17 are arranged in a circle and are concentric with the panel 2, then a battery 3 for supplying power to the ultraviolet LED lamps 17 is arranged in the handle 1, and the on-off of the ultraviolet LED lamps 17 is controlled by a button 4.

As shown in fig. 1 and 2, on the other side of the panel 2, a viewing channel 5 and a lens assembly 6 are provided, which cooperate with each other. Wherein the visual channel 5 comprises a first visual channel 7 fixed on the panel 2 and a second visual channel 8 in threaded connection with the first visual channel 7, that is, by rotating the second visual channel 8, it is possible to move the second visual channel 8 up and down in the longitudinal direction.

As shown in fig. 2, the bottom of the first visual channel 7 is slotted towards the side of the lens assembly 6, thereby enabling the first convex lens 12 or the second convex lens 13 provided in the lens assembly 6 to enter the first visual channel 7 by rotation.

As shown in fig. 2, the lens assembly 6 specifically includes a rotation shaft 9 rotatably disposed on the panel 2, and a knob 11 is disposed at an end of the rotation shaft 9, so that the rotation shaft 9 can be rotated by the knob 11. The bottom of the rotating shaft 9 is provided with a connecting plate 10, and two ends of the connecting plate 10 are respectively fixedly connected with a first convex lens 12 and a second convex lens 13. In practice, more connecting plates and convex lenses can be arranged on the rotating shaft as long as the space is enough.

As shown in fig. 2, a limiting plate 14 is arranged above the connecting plate 10, the limiting plate 14 also rotates along with the rotating shaft 9, and the limiting plate 14 and the connecting plate 10 are in the same vertical plane. Then, elastic plates 15 positioned at two ends of the limiting plate 14 are arranged on the inner wall of the shell wrapping the lens assembly 6 in a staggered mode, so that the function of limiting the rotating shaft 9 which rotates to a specific position to a certain extent is achieved, and the problem of free rotation of the rotating shaft is avoided.

As shown in fig. 2, in order to increase the magnification of the device, a third convex lens 16 is disposed in the second visual channel 8, the third convex lens 16 can be matched with the first convex lens 12 or the second convex lens 13, and the distance between the third convex lens 16 and the first convex lens 12 or the second convex lens 13 can also be adjusted to meet the requirement of different magnifications when screening vitiligo.

In addition, the panel 2 may be made of a completely transparent material, or may be transparent at a portion overlapping with the visual channel 6, or may be transparent at least at a portion overlapping with the visual channel 6. For this reason, if the vitiligo can be observed and screened through the visual channel 6 without being affected, whether the rest part of the panel 2 is transparent or not can be processed according to specific preparation cost, process and the like.

The detailed description is not intended to limit the scope of the patent. Various modifications and changes may be made by those skilled in the art without inventive step within the scope of the appended claims.
