Types And Uses of Protective Glasses

Safety glasses are a kind of glasses with special functions.
The mirror is also different. Such as outdoor anti-ultraviolet glasses, anti-impact glasses and anti-chemical glasses used in factories,
Surgical glasses for hospitals, welding glasses for electric welding, laser protection in laser engraving
Glasses, etc. Protective glasses are also known as labor protection glasses in industrial production and are divided into safety protective eyes
There are two types of mirrors and protective masks, which are mainly used to protect the eyes and face from ultraviolet and infrared rays
Radiation of electromagnetic waves such as microwaves, dust, smoke, metal and sand debris, and chemical solution splashes
Shooting damage.

1. Types and uses of safety glasses

1. Protective glasses against external impact, mainly used to protect the eyes from metal or sand and debris
Mechanical damage. The spectacle lens and spectacle frame should be strong and resistant to shock. There are edging around the frame, and there should be ventilation holes on it. The protective lens can be toughened glass, colloidal bonded glass or copper mesh protective glasses.

2. Protective glasses against chemical solutions are mainly used to prevent chemical damage to eyes caused by irritating or corrosive solutions. Ordinary flat lenses can be used, and the frame should be covered to prevent splashing of the solution.
Usually used in laboratories, hospitals and other places, general medical glasses can be used universally.

3. Anti-radiation protective glasses, used to prevent the danger of excessive ultraviolet rays and other radiation to the eyes
harm. The lens is made of special glass that can reflect or absorb radiation, but can transmit certain visible light
to make. The lens is coated with a bright chromium, nickel, mercury or silver metal film that can reflect radiation; blue
Colored lenses absorb infrared rays, yellow-green lenses absorb both ultraviolet and infrared rays, and colorless lead lenses
Absorb X-rays and rays. For example, common welding glasses require relatively low transmittance of the lens, so the color of the lens is mostly ink; laser protective glasses, as the name suggests, can prevent the radiation of laser to the glasses, so the requirements on the lens are very high, such as The choice of light source, attenuation rate, light reaction time, optical density, light transmission effect, etc., different nanometer (nm) lasers need to use different wavelength lenses.

Effect of Electron Beam I Irradiation on Breaking Strength of Medical Disposable Protective Clothing Material

  Abstract: Disinfection or sterilization is an important part of the production process of medical disposable protective clothing (referred to as medical protective clothing). Compared with ethylene oxide sterilization method, irradiation is faster and more efficient. Since medical protective clothing has strict requirements in terms of protection performance，the radiation effect of its materials has important research significance. The electron beam accelerator was used to treat three kinds of medical  protective clothing  materials polypropylene (PP), polyester fiber (PET) and Tyvek with different absorbed doses. Then the samples were subjected to aging tests for different time. The main performance indicators related to radiation effect in GB 19082-2009 were tested. Test results show that the performances of the three kinds of medical  protective gown  such as resistance to water penetration, resistance to synthetic blood penetration, and filtration efficien...

Design And Nursing Application of Disposable Medical Surgery Sterile Operation Package

  Abstract: Preoperative time-out verification is an important procedure for surgical safety verification. In order to improve the implementation rate and satisfaction of medical and nursing Time-out surgical safety verification, this study designed a disposable medical surgical sterile surgical kit. The time-out indicator label is added to the incision site of the  surgical gown , which meets the use requirements of the time-out confirmation in the operating room. Compared with the old  surgical package , surgeons and nurses have significantly improved the implementation rate and satisfaction of Time-out surgical safety verification (P<0.05). The implementation rate of Time-out surgery safety verification in the new surgical kit group was 100.0%, which was significantly higher than the 70.0% in the old surgical kit group (t=11.863, P=0.001<0.05); the satisfaction of the surgeons and nurses in the new  surgical kit  group They were 95.3±3.5 and 96.2±3.8, w...

Classification of Surgical Gowns

  Surgical gowns   are a type of   isolation clothing  worn for protection from pathogens during surgery. They provide an extra layer of cleanliness and hygiene to the surgical team, which is especially important in the hospital setting where more than one patient may be undergoing surgery at any given time. The first step to choosing a   surgical gown   for your practice is determining what fabric you prefer: cotton or synthetic? Cotton offers superior comfort and breathability but can wear out quicker than some synthetics; whereas synthetic fabrics offer more durability but a less natural feel. Synthetic fabrics also tend to cost less on average than cotton ones do – so it’s really up to you! These fabrics have large pores through which microorganisms can easily flow, resulting in poor barrier qualities. Closely woven textiles should be combined with polyester and long-staple cotton and treated with liquid-repellent fluorocarbons to improve the barrier qu...
