DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] This utility provides the following technical solutions:

[0029] Embodiment 1, in order to solve the problem that the existing phototherapy device is not convenient for patients to wear and use independently, discloses:

[0030] The body 1 has grooves on both sides thereof and lenses 2 of the same structure are arranged therein, and a limiting belt 3 is sewn on the right end of the body 1, and the outer end of the limiting belt 3 extends through and extends to the outer side of the left end of the body 1;

[0031] The device also includes: a sealing plate 6 is slidably installed through the internal groove on the front side of the body 1, and the upper part of the sealing plate 6 extends through the upper outer side of the body 1, and the inner side of the sealing plate 6 corresponds to two lenses 2, and an adjustment mechanism is provided in the internal groove on the left side of the body 1, and the adjustment mechanism can be used to slide and limit the pulled limiting belt 3 through meshing, wherein the adjustment mechanism includes a limiting block 8, and the limiting block 8 is rotatably installed on the left inner side of the body 1;

[0032] The limiting block 8 is in an arc shape, and at the same time, a row of limiting grooves 7 are all in an arc shape. The front side of the body 1 is in an arc shape, which can fit the patient's face.

[0033] The adjustment mechanism also includes a reset spring 9, wherein the reset spring 9 is arranged inside the left side of the fuselage 1, and the outer end of the reset spring 9 is connected to the limit block 8, the outer side of the limit block 8 is engaged and connected to the limit groove 7, and a row of limit grooves 7 are evenly spaced on the inner side of the limit belt 3, the internal groove of the limit block 8 is provided with a torsion spring 11, and the inner side of the torsion spring 11 is wound and connected with a rotating rod 10, and the outer end of the rotating rod 10 extends through to the outside of the fuselage 1.

[0034] like Figure 1-Figure 3 As shown, when the patient needs to wear the mask by himself, after putting the body 1 on the head, the limiting belt 3 is wrapped around the patient's head and then extends through the inside of the body 1, and then the limiting belt 3 is pulled to shrink and tighten. At this time, the reset spring 9 can use its own elastic force to pop out the limiting blocks 8 into a row of limiting grooves 7 in sequence, and then the pulled limiting belt 3 can be slid and limited to avoid the body 1 from loosening and falling off during later treatment. Finally, the rotating rod 10 can be rotated to drive the limiting block 8 to separate from the limiting groove 7, and then the limiting belt 3 can be pulled out and reset, thereby facilitating the disassembly operation of the body 1, saving the auxiliary wearing time of medical staff and improving the use efficiency of the phototherapy device.

[0035] Embodiment 2 is different from Embodiment 1 in that the auxiliary airbag 5 can be squeezed and collided while the limiting belt 3 is pulled to tighten, thereby improving the wearing comfort of the fuselage 1. The following is disclosed:
