Technical Field
The utility model belongs to the technical field of medical supplies, and relates to a white spot surrounding protection covering film suitable for phototherapy or medicine application of vitiligo.
Background
Since white spots are often scattered throughout the body of a vitiligo patient, traditional phototherapy such as NB-UVB or 308nm excimer laser (excimer light) for promoting the compound color of the patient has a certain influence on normal skin except for the white spots during treatment. The normal skin around the patient needs to be covered according to the shape of white spots of the patient with vitiligo. In the past, vitiligo patients cut the covering cloth according to the shape of white spots, and an opening with the same size and shape as the white spots is made for illumination. Firstly, the shading cloth is difficult to fix on the parts such as limbs, hands and feet and the like, and is easy to move and slide; secondly, it is difficult for the patient to self-produce a covering cloth which is completely similar to the shape and size of the white spots when cutting by himself/herself with scissors, and the cutting process is time-consuming and labor-consuming, and there is still a need for further improvement in the technology for the utility model of a suitable protective covering. And the phototherapy is combined with external medicine treatment, so that the white spot can be more effectively promoted to be complex. The improvement of the photosensitive drugs, such as compound cumin tincture, has certain influence on normal skin, avoids being smeared on the normal skin as much as possible, and is also a clinical problem to be solved.
According to the latest consensus of Chinese vitiligo diagnosis and treatment, the effect of phototherapy combined therapy is better than that of single phototherapy, wherein phototherapy combined external medicines (such as external hormone, external calcineurin inhibitor and external photosensitizer) are widely applied clinically. At present, a multifunctional device for protecting the skin around the white spots is still lacking, the requirements of illumination and protection of the skin around the white spots can be met, the requirements of external medicine treatment and protection of the skin around the white spots can be met, the device can be flexibly assembled, and single treatment or combined treatment can be met (when only the external medicine treatment is carried out, a liquid dressing can not be applied, only an application opening can be torn, when only the phototherapy is carried out, the illumination opening can not be torn after the liquid dressing is applied, and when the combined treatment is carried out, the opening can be torn along the depicted outline after the liquid dressing is applied).
As disclosed in chinese patent ZL201921001182.9, a patch for protecting the periphery of vitiligo skin lesion is disclosed, which comprises a tearable patch adapted to be laid on the surface of the skin of a patient and having a middle part easily torn to form a light opening so as to expose the vitiligo skin lesion part, and a reflective film for reflecting light so as to protect the periphery of the vitiligo skin lesion part of the patient, wherein the reflective film is coated on the tearable patch. When the patch is used, the white spot contour cannot be accurately seen due to the fact that the white spot is shielded by the reflective film, so that an opening completely consistent with the white spot contour is affected, and meanwhile, the patch is also only suitable for phototherapy and cannot be used in combination with medicines.
