Description

Prone position dressing treatment chair after ophthalmic operation

Technical Field

The invention belongs to the technical field of ophthalmic surgery, and particularly relates to a prone position dressing treatment chair after ophthalmic surgery.

Background

Complex retinal detachment following vitrectomy + intraocular tamponade requires the patient to be forced to adopt a prone position, which often lasts for 7-14 days after surgery and at least 18-20 hours per day. It has been found that the longer the postoperative downward facing posture is, the better the retinal hole is closed and vision is restored. The existing prone position is realized on a lying bed, so that comfort level of a patient is seriously affected, and the problems of irregular body position, poor compliance and the like of the patient can occur. Moreover, ophthalmic patients are generally older, and have basic diseases such as diabetes mellitus, and the like, and the head and the pressed part are easy to have a plurality of problems such as red skin, pressure sores, unsmooth breathing, and the like. The existing prone position is inconvenient to cool and compress, and is inconvenient to quickly recover wounds.

Disclosure of Invention

The first invention aims to provide an ophthalmic postoperative prone position dressing treatment chair capable of conveniently performing cold and hot compress in prone position, and solves the problem that the conventional ophthalmic postoperative prone position cannot be conveniently subjected to cold and hot compress.

The second invention aims to further provide an ophthalmic postoperative prone position dressing chair which is used for enabling an ophthalmic postoperative patient to keep a facial prone position and limiting the head when sitting normally, and solves the problem that the existing ophthalmic postoperative facial prone position can only be carried out on a bed.

The technical problems are solved by the following technical scheme: the utility model provides an ophthalmic postoperative prone position applies treatment chair, includes chair frame, the front walking wheel of connecting on chair frame lower extreme front side, the back walking wheel of connecting on chair frame rear end downside, the cushion of connecting on chair frame, be located the back behind the cushion, be located two armrests of cushion left and right sides and be located the pushing hands of back upper end, its characterized in that still includes the eye that is located the back side applies the treatment ware, link together through the connecting rod between back and the cushion, form two shank that are located the connecting rod left and right sides between back and the cushion and dodge the breach, chair frame rear end is equipped with the back callus on the sole, patient's face is located two legs and dodges the breach and the foot supports when the seat is on the cushion in one-to-one correspondence; the eye compress device comprises a reflecting cover with an opening end facing the breathing hole and an infrared LED positioned in the reflecting cover, wherein a gas distribution cavity is arranged in the reflecting cover, a plurality of gas outlet channels circumferentially distributed along the reflecting cover are arranged in the wall part of the luminous cover, a gas inlet main pipe is arranged in the gas distribution cavity, one end of the gas outlet channel is communicated with the gas distribution cavity through the communication channel, the other end of the gas outlet channel penetrates through the upper end face of the reflecting cover to form a gas jet, a gas jet pipe with an inlet end connected with the communication channel in a sealing manner is arranged in the gas outlet channel, the gas jet pipe is isolated in the gas outlet channel to form a gas suction cavity surrounding the periphery of the gas jet pipe, the gas suction cavity is provided with a gas suction channel penetrating through the inner peripheral surface of the reflecting cover, and the inlet end of the gas suction channel is positioned below the infrared LED.
