Description

Earcap for ophthalmic surgery

Technical Field

The utility model relates to an earmuff for ophthalmic surgery, which belongs to the technical field of medical instruments.

Background

The effective killing or cleaning of bacteria contaminating the eyelid and conjunctival sac before ocular surgery is an important means for preventing and controlling ophthalmic surgical infections. Conjunctival sac irrigation disinfection is a major step in preoperative preparation, aiming to reduce the incidence of infection. When the eye operation is performed, a patient lies in a horizontal position, eye drops and disinfectant are needed to wash the conjunctival sac before and after the operation, 0.01 ml of normal tears are removed due to the fact that the maximum capacity of the conjunctival sac is 0.02-0.03 ml, the conjunctival sac can only contain about 0.02 ml of liquid medicine at most, and the capacity of 1 drop of eye drop is about 0.05 ml. In actual operation, at least two drops of eyedrops are usually dropped, and redundant liquid flows out of eyes and flows into the back of ears, neck, auricles or auditory canals of a patient along cheeks; the face skin is thin and soft, the blood supply is abundant, the sensory nerve and the motor nerve are distributed densely, the feeling and the reaction are sensitive, even if a small amount of liquid flows down, a patient feels uncomfortable, subconsciously can raise hands to wipe eyes and faces, and the infection chance is increased. It is therefore important to provide the patient with ear protection.

Disclosure of Invention

The utility model aims at solving the technical problems of reducing the uncomfortable feeling of the patient, reducing the infection chance and protecting the ear by avoiding the liquid from flowing into the ear and the neck by the redundant liquid flowing out from the absorbing conjunctival sac in the ophthalmic operation.

In order to achieve the above object, the present invention provides an earmuff for ophthalmic surgery, which comprises an ear patch portion and an auricle portion, wherein the ear patch portion is disposed at the periphery of the auricle portion, and the ear patch portion is provided with a water absorbing layer.

Preferably, the auricle part is provided with a hollow structure, and the auricle part provided with the hollow structure can be sleeved on the ear of the operator and wraps the auricle of the operator.

Preferably, the outer circumference of the ear attachment portion is formed in an arc shape.

Preferably, the material of the water absorption layer is a cotton core.

Preferably, the ear attachment portion is made of a medical nonwoven fabric.

Preferably, the material of the auricle part includes an elastic band and medical non-woven fabric.

Preferably, the material of the auricle part on the side close to the forehead and/or the side close to the lower jaw is an elastic belt.

Preferably, a cotton core strip is arranged on one side of the auricle part close to the eyes.

Compared with the prior art, the utility model discloses following beneficial effect has:

1. the ear muff for the ophthalmic operation is provided with the ear sticking part which fixes the position of the ear muff, fully exposes the skin of a sterilized part and protects the ear on the operation side;

2. the earmuff adopts curved design can be better laminating facial profile, and the liquid that flows down when the art person crouches in the operation has been blocked at curved both ends, has avoided liquid to flow into behind the ear and the neck, and the inside of auricle portion has been shielded to curved central part arch, has prevented that liquid from flowing into in the ear.

3. The auricle part adopts a hollow design, so that the auditory sense and the doctor-patient communication of the patient are not influenced while the ear of the patient is protected;

4. the ear cap of the utility model can adsorb and block the redundant liquid flowing out from the conjunctival sac in the operation when being used in the ophthalmic operation, thereby avoiding the liquid from flowing into the back and the neck of the ear, reducing the discomfort of the patient, reducing the infection chance and protecting the ear, and providing effective protection for the operator wearing the hearing aid; when the preoperative patient is prepared, the earmuffs also play a role in obviously identifying the side eyes during operation.
