Description

Multifunctional medical goggles

Technical Field

The utility model belongs to the technical field of the medical instrument technique and specifically relates to a multi-functional medical goggles.

Background

In daily activities, the traditional goggles can effectively prevent viruses from invading conjunctiva and prevent infection, and become one of necessary protective tools for medical and health personnel. In actual overall protection, various problems exist, as follows:

1. problem of fog production

Because of the use of N95 gauze mask of needs cooperation, its expired gas easily makes the goggles appear the fog, causes visibility to reduce, sight to block. Particularly, medical staff are in diagnosis and treatment such as: when the injection and the water hanging are performed, the operation difficulty is increased, but at the moment, if the goggles are adjusted again, the infection risk is greatly increased. In actual operation, medical personnel often need to carry out defogging through using the antifogging agent to paint the lens, seal the upper edge of gauze mask with the needle pad pasting of keeping somewhere, clean the lens with the liquid detergent three kinds of methods, but antifogging agent is difficult for obtaining, medical personnel sweat soaks makes the pad pasting come unstuck etc. brings very big limitation for the solution, and because the not enough various problems such as cornea oxygen deficiency that lead to easily of long-term circulation of air in the airtight mirror chamber for medical health personnel have great health safety hidden danger in the during operation.

2. Problem of ultraviolet radiation

In epidemic prevention and control, each large medical and health place needs to carry out systematic environmental safety control and management, and ultraviolet disinfection is one of the most main air disinfection modes at present, therefore, each large hospital adds an ultraviolet disinfection area, in addition, because under special circumstances, the shortage of resources such as protective clothing, goggles and the like, daily ultraviolet general disinfection frequency of medical staff is increased, the traditional goggles are thin and transparent, and can not effectively block ultraviolet radiation, thereby increasing the probability of ultraviolet burn of the eyes of the medical staff, and the medical staff is very likely to have skin burn, eyelid redness, conjunctival congestion, photophobia, lacrimation, blurred vision and other symptoms, and if the eyes are exposed to ultraviolet for a long time, part of the eyes may leave sequelae such as cataract and the like. Therefore, the traditional goggles can not shield ultraviolet rays, so that the eyes of medical staff are directly damaged, and the life health of medical staff is seriously threatened.

3. Problem of blue light radiation

Because the workload of medical staff is large, the medical staff is required to be under an LED light source for a long time every day and also to use a computer for recording electronic cases for a long time, so that the common goggles are not capable of preventing blue light after being exposed in an excessive blue light irradiation environment for a long time, and VDT syndrome, which is a disease showing nonspecific symptoms of various systems, can become a 'chronic disease' of first-line medical staff at present, and the physical and psychological health of the medical staff is greatly influenced.

4. Corrosion problem of alcohol

In clinical practice, use medical alcohol to carry out the lens disinfection back to traditional goggles, cause the lens wearing and tearing easily, consequently, medical staff urgently needs a high-level novel goggles, and this goggles's lens has resistant alcohol corrosion, resistant sterilization process's characteristics repeatedly.

5. Wearing experience problem

In epidemic prevention and control, numerous medical workers need to wear the frame glasses, and the existing goggles do not take the problem of containing the frame glasses into consideration, so that numerous front-line medical workers wear the goggles forcibly outside the frame glasses for a long time to cause red and swollen phenomena and severe indentation, great physiological burden is caused to the work of the medical workers, and extremely poor wearing experience is achieved. Furthermore, due to the long wearing time under special conditions, the problem of sweating cannot be avoided, and when sweat or other body fluids gather around the eye socket, the vision of the medical staff is blurred, and the existing protective equipment does not provide a technical means for dealing with the situation.

Chinese patent documents: CN206167173U discloses medical multifocal goggles that pursue, including goggles owner frame, be provided with the mirror holder on the goggles owner frame, be provided with the nose on the mirror holder and hold in the palm, be provided with the multifocal lens that pursue on the mirror holder, be provided with far away on the multifocal lens that pursue and use the district, the bottom in far away with the district is provided with the gradual change district, the bottom in gradual change district is provided with near with the district, one side in gradual change district is provided with the aberration district, the opposite side in gradual change district is provided with the chromatic dispersion district, be provided with the silica gel laminating circle on the goggles owner frame, be provided with discharge valve on the goggles owner frame, one side of goggles owner frame is provided with adapting. By arranging the progressive multi-focus lens on the spectacle frame, when the goggles are worn, the spectacle frame is more comfortable to wear without wearing presbyopic glasses, double images are avoided, the spectacle frame can be used for watching far and near parts at the same time, the running condition of equipment at far can be clearly seen without taking off the spectacles during operation, and the working efficiency is improved; however, the one-way valve is not arranged on the eye protection device, so that the problems that sweat and eye secretion cannot be wiped and the sight line is influenced due to long-time wearing cannot be solved; and the exhaust valve arranged on the valve adopts a through hole type design, and is not suitable for preventing and controlling bacteria and viruses under epidemic conditions.

Chinese patent documents: CN205281038U discloses medical goggles, which comprise two spectacle frames, wherein the two spectacle frames are connected through a spectacle drag, a main lens is installed in the spectacle frame, a leak hole is arranged at the side of the spectacle frame far away from the spectacle drag, and a side lens is installed in the leak hole; the edge part which is contacted with the eyes when the spectacle frame is worn is also provided with a convex edge, and the edge of the inner side of the spectacle pull is provided with silica gel which is attached to the physiological structure area around the eyes when the goggles are worn; elastic belts are arranged at the two ends of the spectacle frame and connected through a fixing buckle; the upper end and the lower end of the spectacle frame are provided with adjusting buckles; this medical goggles simple structure, the lens can effectively prevent the fuzzy sight of fog-forming in the use, the clinical operation of being convenient for, buckle the angle of wearing that changes the goggles through adjusting in the ward use, it is more comfortable to make to wear, wear the in-process, goggles and facial inseparable laminating, the setting through protruding edge and silica gel has been avoided polluting, fine protective isolation effect has been played to clinical medical staff, but on the same as, it also does not provide because sweat and the eye secretion that long-time wearing leads to can't clean, influence the solution of the problem of sight, and be not applicable to the protection work under the special condition such as epidemic situation.
