Why do healthcare workers wear lab coats?

Why is the doctor's work uniform a white coat, and what is the function of the white coat?

Because the people that medical staff come into contact with will bring different pathogens, and medical staff themselves will carry bacteria and viruses, which will bring danger to patients with low immunity. In order to prevent cross-infection and protect the health of medical staff and patients, a white coat with a relatively large barrier area is used as work clothes. It's because it looks clean and makes the patient feel white and noble

In the beginning, the medical staff in the operating room also wore white clothes.

When it comes to doctors, there must be angels in white in everyone's inscriptions, dressed in white. But when doctors have to go for surgery, they change into blue or green clothes.

It turned out that at the beginning, the medical staff in the operating room also wore white clothes, and later people did more and more surgeries, and after becoming more and more experienced, they found that the doctor stared at the red blood for a long time, and suddenly saw the white around him, and his eyes would suddenly be unable to see clearly. That is, when you look at one color for a long time and then look elsewhere, the eye has to produce a tonic in order to balance itself.

As a result, the surgeons during the operation will be affected and will not be able to concentrate on the operation.

This is not the case with green or blue clothing, where blood stains will turn black or brown, thus playing a role in visual adjustment. In order to relieve the visual pressure during the operation, the doctors later changed to blue and green as surgical gowns.

Many aspiring doctors dream of the day when they can finally show off the ultimate symbol of medical legitimacy: the lab coat. In fact, it was such a very important garment that the medical school held a full ceremony – aptly called the "White Coat Ceremony" – to commemorate the first time that incoming students donned bright white clothing.

But white jackets aren't always the norm. If you've watched several period dramas set in the 19th century or earlier, you may think of a family doctor in a black suit. According to Medelita, black makes the most sense both figuratively and literally.

Black clothing is considered formal and sober, so it matches the general tone of a medical visit. It's also much easier to hide spots and stains on dark clothes than on light-colored clothes.

However, by the late 19th century, doctors and scientists began to realize the importance of keeping facilities as clean as possible to prevent bacterial growth and the spread of infectious diseases. White meant cleanliness, and hospitals began transitioning to white sheets and white clothing to reflect their crusade against germs.

As Mark SAs Dr. Hochberg explained in a 2007 article in the American Medical Association's Journal of Ethics [PDF], white also represents something else: authenticity and transparency.

The word frank, which means "frank" and "free from psychological prejudices", is derived from the Latin verb candere, which translates as "white and shiny".

The Doctor's transition from black to white clothing happened quickly, as evidenced by two paintings by the American artist Thomas Eakins. In his 1875 work, The Gross Clinic, Dr. Samuel Gross and his fellow physicians are both dressed in black suits and performing surgery on a man's leg. Less than 15 years later, Eakins painted "Agnew Clinic," which depicts a group of different doctors — this time, wearing white shirts and smocks — operating on another patient.

Although white coats help doctors stand out in crowded hospitals, they are known to have a negative impact on patients. "White coat syndrome" or "white coat hypertension" describes the increase in blood pressure that some people experience when they step into a doctor's office or other clinical setting. Some doctors, especially pediatricians, sometimes skip coats to help patients relax.

In the industry, the white coat is a dust-free garment, which is for hygiene and makes people feel clean. But the dust-free clothing is not just a white coat, the dust-free clothing has different colors and specifications, suitable for different anti-static or clean environments, and the use of dust-free clothing is very wide, including electronics, pharmaceutical, food, bioengineering, optics, aerospace, aviation, semiconductors, precision machinery, hospitals, environmental protection and other industries clean workshops. For the pharmaceutical industry, I would like to introduce to you what conditions the dust-free clothing in the pharmaceutical industry should have.

1. It should have dust-free function. Because if the dust-free clothing is used improperly, or the quality is not good, it will not only contaminate the drug to the operator, but also make the dander on the operator's body leak into the drug, affecting the quality of the drug.

2. It should have anti-static function. With the development of the biotechnology pharmaceutical industry, anti-static dust-free clothing plays an increasingly important role, and the requirements of the pharmaceutical industry for anti-static dust-free clothing are also getting higher and higher.

3. Dust-free clothing fabrics for the pharmaceutical industry. 5mm strip type, 5mm grid, grid fabric conductive silk, in order, its anti-city dust and anti-static effect is getting stronger and stronger;This is also selected according to the level of the clean room, generally class10000 (10,000 area) below the clean room should use 5mm strip conductive silk, class1000 (1000 area) and should use 5mm grid;The class100 (100-level area) clean room should be made of mesh fabric conductive silk.

Combined with the above requirements, the pharmaceutical industry's requirements for dust-free clothing will be much higher, whether the drug can be pure and free of impurities, whether the quality inspection can be passed, dust-free clothing accounts for a large part of the dominance, dust-free clothing for the pharmaceutical industry is not just a piece of clothing, dust-free clothing more represents a safe, sterile health image.
