Description

Technical Field

[0001] The utility model belongs to the technical field of ophthalmic medical instruments and is used for cleaning eyes, in particular to a portable eye washer. Background Art

[0002] During the treatment and care of ophthalmology, eye washing is often required, mainly for washing foreign matter and secretions in the conjunctival sac. The existing portable eyewash can quickly wash the eyes. Its structure can refer to the record of the utility model of portable pressure-sensitive spring-type eyewash with patent number ZL2007201430407, publication number CN201019983Y, and patent name. An eyewash basin is provided at the upper end of the casing, and an inner capsule is provided in the casing at the lower end of the eyewash basin. The upper end of the inner capsule is connected to the lower end of the eyewash basin through an eyewash nozzle, and the lower end of the shell corresponding to the inner capsule is an extrusion and contraction shell.

[0003] Although the existing eyewashers are easy to use, they still have the following defects: 1. The water flow for flushing the eyes requires people to squeeze the outer rubber sleeve and the inner capsule hard to form a single water column. The force is difficult to control and the flushing efficiency of the single water column is relatively low; 2. The existing eyewashers lack a structure to open the eyelids to expose the eyeball and conjunctival sac. When encountering external water flow, the eyelids of the human eye will subconsciously close, resulting in the need for repeated eye flushing, which not only wastes eyewash solution but also delays the patient's follow-up treatment. Summary of the invention

[0009] Furthermore, the liquid outlet holes are distributed on the supporting portion of the flushing hose and on both sides of the supporting portion.

[0010] Furthermore, the three-way pipe extends from the middle of the casing into the cavity of the casing and is fixed thereto.

[0011] Furthermore, the arc-shaped soft cushion is made of waterproof material and has a sticky surface, so it can be closely attached to the eye area and facilitate eye cleaning.

[0012] Furthermore, the internal cavity of the upper half of the casing is set as a wastewater cavity, and the casing is also provided with a drain plug connected to the wastewater cavity to facilitate emptying and cleaning of the wastewater cavity after use.

[0013] Furthermore, two water inlets connected to the waste water chamber are provided in the middle of the casing, and the water inlets are located at the notch of the arc-shaped cushion and obliquely below the flushing hose; when the eyes of a supine patient are cleansed, the waste water is collected into the waste water chamber from the outside of the outer corner of the eye through the above-mentioned water inlets, thereby reducing the outflow of waste water.

[0014] Furthermore, the upper part of the casing is provided with two water receiving ports connected to the waste water chamber, the water receiving ports are located at the maximum diameter of the arc-shaped cushion along the y-axis direction and are arranged close to the inner surface of the arc-shaped cushion; when the eyes of a patient who is half-lying, sitting or standing are cleaned, the waste water is collected into the waste water chamber from under the eyelids through the above-mentioned water receiving ports to prevent the waste water from overflowing.

[0015] The utility model has the following advantages and positive effects:

[0016] 1. The utility model can open the eyelids and clean the eyes by arranging a flushing hose with a positioning bracket inside, and has good cleaning effect and high cleaning efficiency.

[0017] 2. The shape of the flushing hose and the position of the liquid outlet adopted by the utility model are suitable for the shape of the human eye. When flushing, water flows at different angles above and below the eyeball at the same time. The water column is finer, which reduces irritation and is more comfortable.

[0018] 3. The utility model is provided with the function of collecting waste water, which can collect waste water in time when in use, and keep other parts of the head and face dry. BRIEF DESCRIPTION OF THE DRAWINGS
