Description

Prone position dressing treatment chair after ophthalmologic operation

Technical Field

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

Background

After complex vitrectomy + intraocular tamponade, the patient is forced to adopt a prone position which usually lasts for 7-14 days after surgery and needs to be maintained for at least 18-20 hours each day. It has been found that the longer the postoperative face-down position is maintained, the better the retinal tear closure and vision recovery. The existing prone position is realized by lying on a bed, the comfort of a patient is seriously influenced, the patient can have the problems of non-standard body position, poor compliance and the like. In addition, the patients with ophthalmology are generally old and have basic diseases such as diabetes and the like, and the head and the pressed part are easy to have a plurality of problems such as red skin, even pressure sores, unsmooth breathing and the like. The cold and hot compress in the existing prone position is inconvenient, and the wound is not convenient to recover quickly.

Disclosure of Invention

The first purpose of the invention is to provide an ophthalmologic postoperative prone position compress treatment chair capable of conveniently performing cold and hot compress in a prone position, and solve the problem that the cold and hot compress cannot be conveniently performed in the existing ophthalmologic postoperative prone position.

The second invention aims to further provide an ophthalmologic postoperative prone position dressing chair which is used for maintaining the prone position of the face of a patient after ophthalmologic operation and can limit the head when the patient normally sits, and the problem that the existing ophthalmologic postoperative prone position of the face can only be carried out on a bed is solved.

The technical problems are solved by the following technical scheme: the utility model provides an ophthalmology postoperative prone position applies and treats chair, includes the chair frame, connects the preceding travelling wheel on chair frame lower extreme front side, connects the back travelling wheel of chair frame rear end downside, connects the cushion on the chair frame, is located the back at cushion rear, is located two handrails of cushion left and right sides and is located the pushing hands of back rear end upper end, its characterized in that still includes the eye that is located back side and applies and treats the 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, the chair frame rear end is equipped with the back callus on the sole, two legs one-to-one when the patient face is on the cushion to the front seat are located two shank dodge in the breach and the foot supports on the back callus on the sole; be equipped with the layer board on the handrail, be equipped with the breathing hole on the layer board, the eye applies the ware and is located the below of connecting plate, the eye applies the ware and includes the open end orientation the reflector of breathing hole and the infrared ray LED who is located the reflector are equipped with the gas distribution chamber in the reflector, are equipped with a plurality of gas outlet channel along reflector circumference distribution in the wall portion of luminescent shield, and the gas distribution chamber is equipped with inlet manifold, and gas outlet channel's one end is through intercommunication passageway and gas distribution chamber intercommunication, and the other end link up the up end face that the reflector formed the air jet, be equipped with the entrance point in the gas outlet channel with the jet-propelled pipe that intercommunication passageway seal connected together, the jet-propelled the chamber of isolating in the gas outlet channel and surrounding in jet-propelled pipe periphery, the chamber of breathing in is equipped with the passageway of breathing in a perfect understanding the reflector inner peripheral face, and the entrance point of breathing in passageway is located infrared ray LED's below. When carrying out prone position and applying the treatment, the patient back of the body is sat forward on the cushion, and two legs are worn to establish two shank dodge in the breach, under the head put on the layer board and eyes mouth equate the respiratory orifice and align, guarantee respiratory usually. When cold compress is carried out, cold air is input from the air distribution cavity and then output from the air jet port, and the breathing holes are sprayed to the face and eyes of a patient, so that the cold compress effect is achieved. When carrying out the hot compress, make steam from cloth gas chamber input back from the jet orifice output and the respiratory orifice sprays patient's face and eyes on, play the effect to surface course hot compress, open infrared ray LED simultaneously and shine to play the effect of carrying out the hot compress to the wound depth. When hot compress is carried out, the jet pipe generates jet flow, so that air below the infrared LED in the reflecting cover is pumped away, and air above the infrared LED flows downwards, and wind formed beside the infrared LED plays a role in radiating the infrared LED. The hot compress mode can enough carry out the hot compress of surface nexine, adopts infrared ray LED as the light source power saving, and the steam of top layer hot compress usefulness simultaneously can be to reflector inside production wind and realize the heat dissipation to LED, has solved the heat dissipation problem that the LED periphery is surrounded by steam.

Preferably, the opening end of the reflecting cover is provided with a light-transmitting cover plate, the light-transmitting cover plate seals the opening end of the reflecting cover, the reflecting cover is provided with a plurality of air inlets, and the air inlets are positioned above the infrared LED. The heat dissipation effect can be prevented from being influenced by the fact that the sprayed hot gas flows back into the reflecting cover, and therefore the effect of improving the heat dissipation effect is achieved.

Preferably, the air inlet is hermetically connected with the outlet end of the air inlet pipe, and the inlet end of the air inlet pipe is positioned below the reflector. Can make the air that gets into in the reflector more keep away from the eye, the radiating effect is good.
