RU203225U1 - Holder for cleaning and inspection of rigid gas permeable contact lenses - Google Patents

Abstract

The utility model relates to medicine, specifically to ophthalmology, and is intended for cleaning and examining rigid gas permeable contact lenses (RGPL) using solutions, excluding contact of a chemical reagent with the skin of the hands when cleaning the lens, minimizing contact with fingers when examining the lens. model is the convenience and protection of the hands of the medical staff when cleaning hard contact lenses using chemical reagents, protection of the hard contact lens from damage and contamination, as well as the convenience of examining the GPL. The technical result is achieved by the fact that the holder for cleaning and examining hard gas-permeable contact lenses is made of transparent elastic material, consisting of a handle 40-80 mm long with a circular section with a diameter of 4-8 mm or a square section with a size of 4-8 mm on each side, rigidly connected to a retainer 7-9 mm high, 13-14 mm in diameter and 2- 5 mm, which in turn has the shape of an arc, having a base height of 1-2 mm and two limiters 1.5-3 mm high, 0.5-1.5 mm wide each, forming a 1-2 mm wide groove between them to hold the lens.

Description

The utility model relates to medicine, specifically to ophthalmology, and is designed to clean and inspect rigid gas permeable contact lenses (RGPL) using solutions, excluding contact of a chemical reagent with the skin of the hands when cleaning the lens, minimizing contact with fingers when examining the lens.

Known holders and kits for cleaning ZhGKL. Utility model patent 160428 and invention patent RU 2619248.

The disadvantage of these devices is that they are intended only for cleaning lenses, they are made of opaque materials, which makes it impossible to visually inspect the lenses.

Closest to the proposed one is the container holder of the "barrel" type (manufactured by PARAGON CRT, USA) (metronews.ru/partners/novosti-partnerov-162/reviews/linzy-paragon-crt-bezoperacionnyy-metod-lecheniya-miopii-1604395/ , http://diagnoz.info/bolezni/glaza-zrenie/nochnyie-linzyi-paragon.html, https://www.academy-vip.com/linzy-nochnogo-nosheniya.html, in which the lenses are stored upright The sides of the lens retainer of this device are made in the form of circular segments, between which the lens is located and on each side there is a cut-out for easy placement of the lens, and the holder itself is attached with its disk-like base to the screw-on cover of the container.

The disadvantage of the prototype is that it is designed only for storing the lens, it is not intended for cleaning the lenses using various cleaning tips, since it has a short "base-leg" which can only be held with tweezers. The very wide sides of the retainer, made of opaque silicone, make it impossible to visually inspect and clean the lens, especially its peripheral part.

The objective of the utility model is to create a device that allows cleaning hard contact lenses using reagents, excluding direct contact of personnel's hands with the lens cleaning solution, as well as making a visual inspection of the lens after cleaning, without touching it with fingers.

The technical result of the utility model is the convenience and protection of the hands of the medical staff when cleaning hard contact lenses using chemical reagents, protecting the hard contact lens from damage and contamination, as well as the convenience of examining the GPL.

The technical result is achieved by the fact that the holder for cleaning and inspecting rigid gas-permeable contact lenses is made of transparent elastic material, consisting of a handle 40-80 mm long with a circular section with a diameter of 4-8 mm or a square section with a size of 4-8 mm on each side, rigidly connected to a retainer with a height of 7-9 mm, a diameter of 13-14 mm and a width of 2-5 mm, which in turn has the shape of a broken arc, having a base 1-2 mm high and two stops 1.5-3 mm high, wide 0.5-1.5 mm each, forming a 1-2 mm wide groove between each other to hold the lens.

The holder for cleaning and inspecting rigid gas-permeable contact lenses consists of a lens retainer and a handle rigidly attached to it and is made of transparent elastic material such as: silicone, acrylic and other mixtures based on them.

The latch is made in the form of an arc with a height of 7-9 mm, a diameter of 13-14 mm and a width of 2-5 mm. The sectional retainer consists of two stops (front, rear) connected by a base. A groove with a width of 1-2 mm is formed between the stops. The limiters are 1.5-3 mm high and 0.5-1.5 mm wide. The base height is 1–2 mm.

The handle has a length of 40-80 mm, it can be made with a round section with a diameter of 4 mm, or a square section with a size of 4 mm on each side.

A rigid lens is placed between the retainer restraints, which allows safe cleaning of the LPGL using chemical solutions, excluding direct contact of the reagent with the skin of the hands, for example, using felt cleaning tips. The transparency of the device material allows visual control when examining the LHGPL, and the elasticity and low adhesion of the retainer material allows the lens to be tightly fixed in the holder.

Holding the holder by the handle, with the lens installed in the holder, the ZHGPL is cleaned with a chemical reagent using a cleaning tip, which protects the lens from mechanical damage, as well as the hands of the medical staff from the effects of a chemical reagent.

After the performed manipulations, the lens is washed with the required amount of 0.9% NaCl solution and, without removing it from the retainer, a visual inspection is performed. If there are no comments, the lens is removed from the retainer; if there are comments, these cleaning procedures are repeated again.

Thus, the proposed holder for cleaning rigid gas-permeable contact lenses is effective and safe for carrying out the lens cleaning procedure using chemical reagents, and is also convenient for visual inspection of the lens without removing it from the holder.
