Eyelid opening device for ophthalmic nursing

Abstract

The invention provides an eyelid opening device for ophthalmic nursing, relates to the technical field of medical instruments, and aims at solving the problems that when an existing eyelid opening device is used, the existing eyelid opening device needs to be fixed to the head of a patient or is of a pure handheld structure, the stability and accuracy of the existing eyelid opening device both have certain defects, the opening device fixed to the head of the patient is limited in use condition, when human eyes are blocked by external objects, reflection nerves can reflect naturally, eyelids jump constantly, and therefore the eyelids are difficult to open. The eyelid opening device includes a supporting frame. A lifting moving seat is vertically mounted at the upper end of the supporting frame in a sliding manner; a horizontal brake mechanism is fixedly installed in the middle of the upper end of the lifting moving base, and the front end and the rear end of the brake mechanism are tangent to the front end and the rear end of the supporting frame respectively. Due to the fact that the vertical rod is sleeved with a spring A, the eyelid opening action can be operated at the designated height, convenience and high efficiency are achieved, and when a finger is loosened, automatic reset can be achieved under the action of a spring B.

Problems solved by technology

[0006] In order to solve the above-mentioned technical problems, the present invention provides an eyelid stretching device for eye care, to solve the problem that the existing eyelid stretching device either needs to be fixed on the patient's head or is a purely hand-held structure when in use. There are certain disadvantages in the accuracy and accuracy of the device. The use of the stretching device fixed on the patient's head is limited. When the human eye is blocked by an external object, the reflex nerves will naturally reflex, making the eyelids keep beating, which will cause the eyelids to stretch. difficult question
