2. Control methods: Set up a disease-free farmland and select disease-resistant varieties. The key to good seed treatment is to avoid damage to roots when pulling the seedlings. Hybrid rice seeds can be soaked for 24 hours with 25% scopolamine (chlorprolactinol and chloric acid) EC 1500-2000 times. To ensure the effect, the soaking time should not be less than 12 hours. Conventional seeds should be immersed for 48 hours in 2000-2500 times. After soaking, direct germination or soaking with 40% chlorothalonil 600 times liquid for 24-36 hours, remove and rinse with clean water before planting germination.
Surgical gowns, as necessary protective clothing during the surgery, are used to reduce the risk of medical personnel coming into contact with pathogenic microorganisms, and can also reduce the risk of pathogenic microorganisms spreading between medical staff and patients. It is a safety barrier for sterile areas during surgical operations .
* Scope of use of surgical gowns: can be used for surgical operations, treatment of patients; anti-epidemic inspection in public places; disinfection in virus-contaminated areas; can also be widely used in military, medical, chemical, environmental protection, transportation, epidemic prevention and other fields.
* Classification of Surgical Gown
1. Cotton surgical gown. Medical institutions are the most widely used and most dependent surgical gowns. Although they have good breathability, they have poor barrier protection. The cotton material is prone to shedding of flocs, so that the annual maintenance cost of the ventilation equipment of the hospital will also have a large burden.
2. High density polyester fiber fabric. This type of fabric is mainly composed of polyester fiber, and conductive materials are embedded on the surface of the fabric, so that the fabric has a certain antistatic effect, thereby improving the comfort of the wearer. This kind of fabric has certain hydrophobicity, it is not easy to produce cotton de-flocking and the advantages of high reuse rate. This kind of fabric has good antibacterial effect.
3. PE (polyethylene), TPU (thermoplastic polyurethane elastic rubber), PTFE (teflon) multi-layer laminating film composite surgical gown. The surgical gown has excellent protection performance and comfortable breathability, which can effectively block the penetration of blood, bacteria and even viruses. But the popularity in China is not very wide.
4. (PP) polypropylene spunbond fabric. Compared with the traditional cotton surgical gown, the appearance of this material is because of its low price, and has certain advantages such as antibacterial and antistatic, so it can be used as a material for Disposable Surgical Gowns, but the ability of this material to resist hydrostatic pressure is relatively Low, and the blocking effect of the virus is relatively poor, so it can only be used as a sterile surgical gown.
5. Water spur cloth composed of polyester fiber and wood pulp. Generally only used as a material for disposable surgical gowns.
6. Polypropylene spunbond-meltblown-spun. Adhesive composite non-woven fabric (ie SMS or SMMS): This material is a high-quality product of a new type of composite material. Hydrostatic pressure capacity. SMS non-woven fabrics are widely used at home and abroad, often used to make high-grade surgical gowns.
* Structural design of surgical gown
New protective surgical gown
By providing a protective collar, the neck of the operator can be kept warm. By setting a hand guard pocket, it is helpful for the operating staff to temporarily put their hands in the hand guard pocket while waiting during the operation, which plays a protective role, and is more in line with the principles of aseptic operation and occupational protection.
By setting the contraction cuff, it is helpful to fit the cuff to the wrist, prevent the cuff from loosening, and prevent the glove from slipping out during the operation, which may expose the operator's hand to the glove.
The design of the new humanized protective surgical gown has been improved in the key areas of the surgical gown. The two areas of the forearm and chest area are double thickened, and there are hand pockets in front of the chest and abdomen. By setting reinforcement tablets (double-layer structure) in key areas, it is helpful to improve the ability of surgical gowns to resist water permeability and improve safety.
* Performance of surgical gown
The performance of surgical gown mainly includes: barrier performance, comfort performance.
1. Barrier performance mainly refers to the protective performance of surgical gowns. Its evaluation methods mainly include hydrostatic pressure, water test, impact penetration, spraying, blood penetration, microorganism penetration and particle filtration efficiency.
2. Comfortable properties include: breathability, water vapor permeability, drape, quality, surface thickness, electrostatic properties, color, reflectivity, odor and skin sensitization, and the effects of design and sewing in garment processing. The main evaluation indicators are air permeability, moisture permeability and charge density.
* Why is the surgical gown green?
In the operating room, if doctors, nurses and other staff wear white coats, because the doctors always see bright red blood stains during the surgery, for a long time, occasionally turning their attention to the companion's white coat You will see spots of "green blood stains", which will confuse vision and affect the surgical effect. The use of light green fabric for surgical gowns can not only eliminate this green illusion due to visual complementary colors, but also reduce the fatigue of the doctor's optic nerve, thereby ensuring the smooth operation of the operation.
