Problems solved by technology

[0004] In fact, each type of phototherapy machine is recommended to have an optimal irradiation distance, but few methods for confirming the irradiation distance are provided, which brings inconvenience to clinical practice
At present, there are people who install the steel tape on the phototherapy machine, and pull out the steel tape before the irradiation to adjust the distance between the phototherapy machine and the irradiated part and realize the fixed distance; Contamination or infection by contact with

Embodiment Construction

[0024] like figure 1 As shown, the figure shows a schematic diagram of the method for locating the irradiation distance of the phototherapy instrument of the present invention. Here, the flexible light guide phototherapy device is taken as an example, but it can be understood that the method of the present invention can also be applied to other types of phototherapy devices, which will be understood hereinafter.

[0025] According to the present invention, in the phototherapy device, two visible light semiconductor lasers 2, 2' are obliquely installed on both sides of the irradiating light output head 11. According to the distance H between the phototherapy device and the irradiated skin surface, two The angle 2α between two lasers, and then calculate the distance L between the two lasers 2, 2', and fix the lasers in the phototherapy apparatus.

[0026] In this method, the semiconductor lasers used can emit red light or green light at the same time, or one red and one green. ...

Abstract

A method for determining the radiation distance of a phototherapeutic apparatus features that two visual laser devices are obliquely installed at both sides of light source and the distance between said two laser devices can be calculated according to the distance between skin and phototherapeutic apparatus and the included angle between said two laser devices by tangent function.

Description

technical field [0001] The present invention relates to the field of skin disease treatment, a method and device for irradiating distance positioning in a phototherapy instrument used in dermatology. Specifically, the present invention relates to a method for using a laser to determine distance in a phototherapy instrument and phototherapy using the method instrument. technical background [0002] Phototherapy is widely used in dermatology. Patients usually need continuous treatment for 6 to 8 weeks or even longer. During phototherapy, the distance between the irradiation light source and the skin surface is directly related to the irradiance received by the skin surface lesion (irradiated to the unit area) The light power, unit: mW / cm2), the curative effect and side effects of phototherapy are all related to the irradiation dose (the product of irradiance and time). [0003] Therefore, in order to ensure the curative effect and reduce the occurrence of adverse reactions, ...
