Description
Technical Field
The invention relates to the technical field of medical functional textiles, in particular to a safe cool medical operating coat based on nano-composite and a preparation method thereof.
Background
The operating coat is used as a necessary protective garment in the operation process, is used for reducing the risk of medical staff contacting pathogenic microorganisms, can also reduce the risk of pathogenic microorganisms spreading between the medical staff and a patient, and is a safety barrier of an aseptic area in the operation.
Currently, the categories of surgical gowns mainly include:
1. the all-cotton operating gown is the operating gown which is most widely applied in medical institutions and has the strongest dependence, and although the all-cotton operating gown has good air permeability, the barrier protection function is poor. The cotton material is easy to fall off, so that the maintenance cost of the ventilation equipment of hospitals every year has no small burden, and the cotton material is often a good habitat of microorganisms and becomes an important spreading source of diseases.
2. The high-density polyester fiber fabric mainly takes polyester fiber as a main material, and a conductive substance is embedded in the surface of the fabric, so that the fabric has the advantages of certain antistatic effect and certain hydrophobicity, cotton fibre is not easy to be removed, and the reuse rate is high. But is stuffy and uncomfortable for the wearer.
3. The PE (polyethylene), TPU (thermoplastic polyurethane elastomer) and PTFE (polytetrafluoroethylene) multilayer laminated film composite operating coat has excellent protective performance and can effectively prevent blood, bacteria and even viruses from penetrating. But is also hot and stuffy, and the comfort of the wearer is poor, so the popularity in China is not very wide.
4. Disposable operating gowns:
compared with the traditional cotton cloth operating gown, the disposable operating gown made of polypropylene (PP) spun-bonded cloth is low in price and has the advantages of certain antibacterial property, certain antistatic property and the like, so that the disposable operating gown can be used as a material of the disposable operating gown, but the antistatic pressure of the material is lower, and the blocking effect on viruses is poor.
The disposable operating gown made of the composite non-woven fabric is a high-quality product of a novel composite material, and the material has high hydrostatic pressure resistance after being subjected to three-resistance (alcohol resistance, blood resistance, oil resistance), antistatic property, antibacterial property and the like, is widely applied at home and abroad, and is commonly used for making high-grade operating gowns.
The polyester fiber and wood pulp composite spunlace fabric is generally only used as a material of disposable operating gowns.
However, the disposable operating coat is disposable, is relatively wasteful and is not in accordance with the current green environmental protection concept.
In 2019, 30 months 7, YY/T0506.8-2019, part 8 of surgical drapes, surgical gowns and cleaning clothes for patients, medical staff and instruments are issued by the State drug administration general administration: the series standards of the special requirements of products, etc., are implemented from 8 months and 1 day in 2020; from the product standard and the industry category, the medical protective product is defined in a clear specification.
While efforts have been made to protect the surgical incision of a patient from infection, there is no much attention paid to the need for self-protection of medical personnel, and as the awareness of protection has increased, surgical gowns are becoming more and more aware of the need to effectively block the extravasation of body fluids and irrigation fluids from the patient in addition to protecting the surgical incision from infection. In the operation process, blood, urine, saliva, ascites, intracavity flushing fluid and the like containing pathogenic bacteria permeate into the body of an operator through the cotton cloth operating gown, sweat of a doctor can permeate into the incision of the patient through the cotton cloth operating gown to cause cross infection between the patient and medical care personnel, and the operating gown prevents the cross infection in the operation process and plays a vital two-way protection role.
The performance of the surgical gown mainly comprises: protective properties, comfort properties and sufficient strength. The protective property is the most important performance requirement of the surgical gown material, and mainly comprises liquid barrier, microorganism barrier and barrier to particulate matters.
Repeated use of the gown requires washing, which can cause cross-spread and infection of different pathogens. Meanwhile, the washing equipment is in a wet state for a long time, so that the washing equipment is very suitable for breeding and propagating germs, and becomes a secondary germ pollution source. The washed operating coat can generate secondary pollution due to the contact with the environment or the bacteria breeding on the packaged articles in the processes of storage and transportation. The disinfection is carried out in the washing process, so that the secondary pollution in the storage and transportation processes after washing cannot be solved, and the germ transmission and breeding of personnel in the use process cannot be solved. Therefore, studies on the necessity of applying antibacterial techniques and products to hospitals, the application range in hospitals, the applicability in hospitals, and the like must be intensively conducted.
The antibacterial textile can avoid cross infection caused by shuffling of different articles in the washing process and secondary pollution after washing; the washed article can be kept sanitary for a long time in the using process, and the infection to a user caused by the fact that germs carried by people are left on the article and breed is avoided. The antibacterial fiber is generally formed by introducing a substance capable of inhibiting the growth of bacteria to the surface or the inside of the fiber by a physical or chemical method, and the antibacterial agent not only can not easily fall off on the fiber, but also can keep a lasting antibacterial effect by balanced diffusion in the fiber.
Meanwhile, when medical staff select the operating gown in the medical rescue work, the air permeability and the comfort of the product cannot be ignored on the premise of considering the performance of the operating gown. Particularly, in order to achieve the required protective effect, the protective clothing fabric is usually subjected to lamination or film coating treatment, and is often heavy and poor in air permeability and moisture permeability. Medical personnel wear for a long time, and the health can produce a large amount of heats, if can not in time discharge, can increase its dysphoria and feel, influence work efficiency and healthy.
Only the comfort of wearing of the operating coat improves, and operation that can be better is operated to other medical staff in surgeon and operating room, improves operation efficiency, reduces misoperation risk. If the operating coat is uncomfortable to wear, the quality of the operating coat can be influenced, if the operating coat is poor in ventilation and heat dissipation, medical personnel can sweat easily during the operation, and the sweat of the medical personnel can pollute the ground or a patient easily to cause bacterial infection of the patient. The mesh cloth is mainly added to the inner layer of the existing surgical gown or other measures on the structure of the garment are taken, so that medical workers can not attach to the surgical gown and increase the ventilation and heat dissipation performance.
In addition, the surgical gown must ensure sufficient strength during wearing and use, otherwise, it may be stretched and damaged; if worn during surgery, they are sometimes punctured by sharp objects such as needles and scissors, which provide a path for the transmission of bacteria and viruses, greatly impairing the protection of the material, exposing the medical staff and the patient to an environment that may be invaded by germs, increasing the chance of infection.
