Disposable Gloves History-www.ycmedi.com
1. From scratch, the first medical gloves were made in the 1890s.
In 1889, when Johns Hopkins Hospital was founded, William Halsted, a professor of surgery, hired Caroline Hampton as the head nurse in the operating room. Later, Katherine's skin became irritated from constant exposure to disinfectant on her hands (which contained mercury chloride and carbolic acid) and she could no longer work. To keep his right-hand man, Holst, a professor of surgery, ordered thin rubber gloves at the Goodyear Rubber Company in New York, which protected his hands from disinfectant. In June of the following year, Catherine married Holst, and the first pair of medical gloves made such a romantic story.
Since then, rubber gloves have entered the medical field, with more nurses and assistants wearing them to work. Dr. Joseph Bloodgood was the first to wear gloves during surgery in 1896. In 1899, Bradgood published an article listing 450 hernia operations, in which infections were reduced by almost 100% by wearing gloves. After that, it became customary for medical staff to wear gloves.
2. Most of the early medical gloves were latex gloves, which experienced the transition from powder to powder-free.
are made from natural latex, and sulfur and lead carbonate are added during production to stabilize the latex and make it softer and more elastic than dry rubber.
Early latex gloves tended to stick together and were difficult to wear. By the end of the 19th century, manufacturers had added talcum powder or lycopene powder to the lining of gloves. The powder lubricated and solved the problem of latex gloves being difficult to slip on and off. But it has also created a new danger. The powder can cause wound infection.
Until 1947, the powdered medical gloves were used to this day, replacing talcum powder and lycopene powder with corn flour treated with Eph (which is easily absorbed by the body).
On December 16, 2016, the US Food and Drug Administration (FDA) made a final decision to ban powdered gloves from medical practices.
In January 2018, China's State Food and Drug Administration (CFDA) raised concerns about the risks of powdered medical gloves and advised caution in clinical operations, invasive procedures, and people with allergies. More and more industries are beginning to pay attention to the dangers of powdered gloves.
Before this, the production process of powder-free gloves had been developed. The glove industry mostly uses chlorine washing to clean gloves to reduce powder content and reduce surface adhesion, making gloves easy to wear. Powder-free gloves are becoming mainstream in the market.
3, Natural latex cost is high, easy to allergy, synthetic rubber into the medical glove industry.
Although the use of natural latex gloves is good, in the course of development, also exposed a lot of defects.
First, natural latex contains some protein components, easy cause allergic reactions in the human body.
Second, demand exceeds supply and cost is high. The main origin of natural latex is limited to Southeast Asia, and the production is also limited by the growth cycle of rubber trees, and the supply of raw materials is limited. The large-scale outbreak of war and disease further intensified the situation of "short supply" of natural latex, resulting in rising raw material prices and increased production costs of latex gloves.
To cope with the shortage of natural latex, many countries began to develop synthetic rubber materials.
1926, in the United States, synthesized PVC and add a variety of additives plasticizing, so that PVC becomes more flexible and easier to process materials, has been widely used in commercial applications.PVC gloves rose in the United States, and gradually transferred to Japan, China, China has been the world's largest output of PVC gloves production base.
Nitrile rubber (a copolymer of butadiene and acrylonitrile) was first made in Germany in 1931, but it was not widely used until 1991, and later expanded to medical gloves.
4. Due to the pressure of environmental protection and the avoidance of latex allergy, the medical glove industry has ushered in a new revolution -- the medical gloves of polymer material should be born at the right time.
From January 1, 2021, the strictest plastic ban in history will take effect nationwide.PVC (polyvinyl chloride) used to be the world's largest production of universal plastic, in front of the ban, the production of PVC gloves environmental assessment and market demand is bound to be limited.
Most Nitrile gloves
use the traditional chlorine washing process, although no powder, but if improperly treated, easy to produce chloride residue; And over time, the release of chlorine molecules makes gloves prone to a pungent odor.
Natural latex gloves due to easy allergy, as well as price fluctuations, high cost, global market share is also decreasing year by year.
The medical gloves market put forward higher requirements for products, non-allergenic, large elastic, stable price of polymer medical gloves should be produced in time. The new reform is mainly carried out from two directions: one is the innovation of production technology, the other is the innovation of raw materials.
The nano nitrile gloves produced by YICHANG
are an improvement in the traditional nitrile gloves production process. They use polymer coating instead of chlorine washing to make the inner layer of the gloves smooth and powder-free. Gloves have no irritating odor, and the production process and glove products are more environmentally friendly and safe. Nano nitrile gloves also show high resilience, no deformation of excellent performance, better user experience.
YICHANG's core product, water-based polyurethane gloves, uses the fourth generation of polymer materials to innovate the performance of Disposable gloves
. The most intuitive improvement lies in elasticity. Waterborne polyurethane gloves have high tensile strength and high tensile ratio and are also known as "high elastic gloves" in the industry. Secondly, with the thin-film coating process, the gloves are more sensitive and can be operated by touch screen and fingerprint recognition.
YICHANG Medical gloves keep pace with The Times in the era of intelligent Internet, ensuring efficient protection and maximizing the flexibility of hands.
