Embodiment Construction

[0013] specific implementation plan

[0014] figure 2 As shown, ① LED chip is welded on ② flexible circuit board, and transparent silica gel is coated on the surface of the chip to make a high-power LED flat transparent soft-based conformal phototherapy body. The flexible illuminant is fixed in the ④ soft substrate made of silica gel, and the ⑤ power connector socket connected to the LED chip is fixed on the edge of the soft substrate to connect the power supply of the LED chip. ③ Highly transparent polyester film is pasted on the ④ soft substrate and ① On the LED chip, it can not only prevent the chip from contacting with the outside world, protect the transparent silicone film coated on the chip surface, but also prevent foreign dirt from adhering to the surface of the LED chip and affecting the light output, which is convenient for cleaning and disinfection.

Abstract

An LED planar transparent soft-base conformal phototherapy body is provided. The soft-base conformal phototherapy body capable of bending with changes of human body shape is used for human skin-contacting irradiation therapies in medical treatment, and is composed of high-power LED chips, flexible circuit boards, flexible silica gel plates, and high-transparency polyester films. The high-power LED chips having wavelength of 510-910nm and irradiating power density of 1-150 mW/cm2 are adopted as irradiation sources , and light output power density may be changed by adjusting current magnitude. The LED planar transparent soft-base conformal phototherapy body is suitable for large spot irradiation therapies of tissue damages and inflammations, bone joint degenerative changes and aches, and body surface photodynamic therapy.

Description

technical field [0001] The invention uses an LED light source to produce a flat transparent soft base light irradiation treatment body, which is suitable for human skin contact irradiation treatment in medical treatment. technical background [0002] In modern photomedicine, the phototherapy instruments used include laser therapy instruments, red light therapy instruments, infrared therapy instruments, ultraviolet therapy instruments and other phototherapy instruments. Whether the light source of these phototherapy instruments is a point light source or a planar light source, they are all fixed on a hard substrate, and the emitting light source cannot be bent. Since the light propagates in a straight line, when the light emitted by the light therapy device irradiates the skin of the body, the light power density received by the skin at different angles is different, especially when the angle of the skin in the lesion treatment area changes greatly, such as the neck , face, ...
