Eyelid function corrector

Abstract

The invention discloses an eyelid function corrector. The corrector comprises a glasses frame and a glasses rack and relates to the field of medical instruments. The eyelid function corrector further comprises power supplies, electric wires, a motor, a gear, a cam group, a leverage pair and an eyelid laminating device group. The electric wires are arranged on the glasses rack. First ends of the electric wires are connected with the power supplies. Second ends of the electric wires are connected with the motor. The motor is located in the central connection position of the glasses frame and connected with the gear and drives the gear to rotate. The cam group matches with the gear and supports the leverage pair. The leverage pair is arranged at the upper part of the glasses frame and connected with the eyelid laminating device group. The eyelid laminating device group performs motion in the manner of matching the leverage pair. The eyelid function corrector has following beneficial effects: by simulating motion of eyelids of a normal person, the field of vision of a patient suffering ptosis is recovered in the natural physiological state and the health of the microenvironment of an ocular surface is maintained.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an eyelid function corrector. Background technique [0002] In clinical practice, especially in the course of specialized diagnosis and treatment of orbital diseases, patients with ptosis and eyelid insufficiency are often seen. Ptosis will cause the upper vision of the patient to be blocked when looking up, which will bring great harm to the work and life of the patient. The inconvenience, even constitutes a serious impact on the patient's safe walking. [0003] The current mainstream treatment method is to use surgery to lift the eyelids. However, when the patient sleeps after the operation, the eyelids cannot be completely closed, which will cause damage to the ocular surface. In severe cases, corneal ulcers may even occur and cause blindness. It is precisely because of this serious surgical complication that a considerable number of patients, for example, patients with negat...

Problems solved by technology

However, this method only supports the eyelids, which will make the patient feel greater resistance when closing the eyes, which is easy to cause fatigue and is not suitable for long-term wearing; at the same time, the "eyelid patch" cannot make the patient's eyelids look normal Humans move in a rhythmic way, so it is difficult for the patient's ocular surface to maintain the normal coverage of the eyelid conjunctiva and the moisture of tears, so as to achieve the ocular surface state of a normal person

And the elastic potential energy is difficult to control when exercising the function, because the severity of each patient's disease is different, it is difficult to apply to every patient
