Description

Vitiligo traditional chinese medicine illumination machine convenient to carry

Technical Field

The utility model belongs to the technical field of medical instrument, concretely relates to leucoderma traditional chinese medicine lighting machine convenient to carry.

Background

Vitiligo is a relatively common acquired pigmentary skin disease and is characterized by complete loss of pigment from local or generalized skin mucous membranes. The loss of melanocyte function in the skin, but the mechanism is not clear. All parts of the body can occur, usually in the dorsum of the finger, wrist, forearm, face and neck.

The existing treatment for vitiligo is as follows:

1. hormone therapy

(1) The system is mainly suitable for patients with generalized progressive vitiligo. The hormone is orally or intramuscularly injected to stabilize the leucoderma in the advancing stage as soon as possible.

(2) Local treatment, topical glucocorticoid is effective for treating limited vitiligo, but adverse reaction caused by long-term topical glucocorticoid should be noticed. The clinically commonly used medicines comprise halometasone ointment, mometasone furoate cream and the like.

2. Phototherapy and photochemotherapy

(1) Phototherapy with narrow-wave ultraviolet (NB-UVB) has certain effect on treating limited or generalized vitiligo.

(2) Photochemotherapy (PUVA) is a better treatment option for local externally-applied furocoumarins (8-MOP, psoralea tincture) and solarization of the limited vitiligo, and can be used for adults and children over 5 years old.

3. Transplantation therapy

It is suitable for patients with stable stage, few skin lesions for several days, and no scar. Common methods include autologous epidermal transplantation, microdermabrasion, autologous cultured melanocyte transplantation, etc.

4. Immunosuppressant

The externally applied calcineurin inhibitor (tacrolimus, pimecrolimus) has certain effect on the parts which are not suitable for using hormone or in order to avoid adverse reaction caused by long-term application of hormone.

5. Vitamin D3 derivatives

The vitamin D3 derivative can be used in combination therapy with NB-UVB, PUVA, etc. Can also be used in combination with topical hormone and calcineurin inhibitor.

In order to facilitate treatment and save cost, most of the existing patients select phototherapy, and the existing vitiligo light camera is large in size, complex in structure, high in cost and inconvenient to carry.

According to an embodiment of the present application, referring to fig. 1-3, the portable vitiligo traditional Chinese medicine illumination machine according to the present scheme includes a device body 1, a display screen 2 and an illumination probe 6, wherein a plurality of ultraviolet lamps 7 are disposed in the illumination probe 6 for treating vitiligo through illumination.

The illumination probe 6 is connected with the handle 5, and a lead 9 of the illumination probe 6 passes through the handle 5 to be connected with the MCU in the device body 1.

The device body 1 side is seted up recess 10, the inside fixed mounting clamping jaw 11 of recess 10, and illumination probe 6 is inside to be set up a plurality of ultraviolet fluorescent tubes 7, and handle 5 is connected to illumination probe 6 bottom, and handle 5 holding is in the clamping jaw 11 of recess 10 inside, and then realizes illumination probe 6 fixed, and when using, accessible handle 5 carries out illumination probe 6's use, and then realizes the treatment.

The handle 4 is arranged at the top of the device body 1, so that the device is convenient to carry and use.

A plurality of universal wheels 8 are fixedly installed at the bottom of the device body 1, and movement is facilitated.

The central position in 1 top of device body installs handle 4, and handle 4 one side sets up display screen 2 and a plurality of button 3, and a plurality of buttons 3 are used for the input of instruction.

Referring to fig. 4, the MCU is integrated inside the device body 1, and is electrically connected to the display screen 2, the step-down voltage regulator and the control circuit, respectively; the control circuit is electrically connected with a plurality of ultraviolet lamp tubes 7 in the illumination probe 6 through wires 9; the step-down voltage stabilizer is connected with the power supply.
