Clinical application of medical plastic aseptic packaging materialsClinical application of medical p

Sterilization and supply center of hospital is the hospital of aseptic central station,is important for a variety of aseptic equipment department, dressings and otheraseptic goods to the whole. In order to strengthen the scientific management ofdisinfection supply center, ensure the medical quality, provide sterile reasonablefor the hospital, to meet the needs of clinical treatment and nursing, central supply room should be according to the characteristics of the clinical use of asepticpackaging materials, the traditional method of making improvements, using disposable plastic sterilization packaging materials. Plastic packing bag is made of a special material produced, with bacteria barrier, packaging equipment itemsnot only beautiful, perspective, and after sterilization can save at least half year.The advantage of paper-plastic packaging, will be clinically necessary but very low frequency instrument package for paper-plastic package. Introduce as follows now.

A, paper-plastic packaging characteristics

1, paper-plastic packaging performance

Paper packaging materials suitable for pressure steam sterilization, ethylene oxide sterilization, low temperature steam and formaldehyde sterilization.

The validity period of sterilization items stored in the packaging materials,performance and quality, sealing tightness, sterilization quality, storage conditions, mode of transport, touching the times and other factors. Plain weavecloth and open type rigid containers, bacteria barrier effect is limited, at 25 ℃ for10 ~ 14 d, wet and rainy season time more short. Plastic packaging materials,bacteria barrier durability, preservation period of up to six months to. Central sterile supply spare many kinds of goods, quantity, but there are some very low frequency (such as packet

Incision of trachea, tracheal cannula, vein incision pack), often because of short effective period and frequent sterilization. The paper packaging materials not onlyextend the period of valid, ensure the safety use of sterile package quality and clinical, but also greatly reduces the incidence of sterilized goods especially bagcloth dilapidation, rubber item adhesion and metal articles rust loss, prolonging the service life of articles.

2, paper and plastic packing material advantages

Paper packaging materials transparent film composed of multi-layer composite membrane, and bacterial resistance performance is good, long storage time, in 150 ~ 180 ℃ sealing pressure sealing machine and retention time tight sealing;pyrogen test of sterilized articles, bacterial culture of chemical indicative cardsmonitoring, monitoring, sterilization indicators reached the requirements.

Good penetrability, can make the gas permeability and sterilization, and candischarge cold air bag, achieve complete sterilization effect; good drainage,weight per square metre of 56 ~ 70 g paper-plastic packaging materials, the formation of drainage not the paper caused by instrument condensation in steam sterilization of water in the sterilization process; hot and humid in the paper, thetoughness is good, no crack.

Plastic packaging bags printed in two kinds of chemical discoloration pressuresteam and ethylene oxide indicator point (the equivalent of package chemical instructions tape role), can be shown in different colors from the appearance ofthe clear differences between this article whether after sterilization. Easy to manage, can be directly to the package name, sterilization date, valid, the operator's name, check the names written on paper, a paste chemical instructions tape and label trouble.

The use of paper packaging to reduce the loss of all kinds of unusual packagesterilization costs and objects; the sterilized goods storage time is short, expireditems must be clean again, packaging, packaging needs to replace the suture needle, thread, blade, after washing the cloth bag, bag to put chemical index card,bag of paste chemical instructions tape, and the need to increase the loss ofsterilization, disinfection center. At present, the types of operation was increased,the increase in sterile packages, many are not commonly used in aseptic package utilization rate is relatively low, but still clinical first aid and treatment is indispensable, sterilization is time-consuming and laborious, these for paper-plastic packaging materials packaging, not only stored for a long time, but alsocan supply clinical use, does not need to be repeated sterilization, reduce loss.The use of paper packaging materials, to ensure sufficient reserve operation use goods, avoid every day search this kind of goods, reduce hand touch asepticpackage number, sterilization cycles that are not commonly used sterilizationitems from the original 1 times a week, down to every year 1 times, repeated sterilization rate is reduced greatly, also reduced the loss rate of sterile items.

Two, should pay attention to the problem

A single device packaging, to choose the appropriate size of paper and plastic packaging materials; tool should notice to use small yarn wrapped into paper-plastic packaging, in the transport process, to prevent preservation packaging bagpuncture. Device packaging, a sealing head space slightly bigger, articles 3 ~ 5 cm from seal, to prevent the paper-plastic packaging material for sealing wrinkle.Articles to be sterilized pot, with stainless steel basket containing, side, if theplastic face flat may cause water retention in the plastic surface; between the plastic and plastic surface can not directly contact.

Selection of the temperature at 150 ～ 180 ℃ sealing machine, temperatureadjustment at 180 ℃, plastic strip width of 2 cm, adopts a double-layer sealing to ensure sealing tightness and tension.

When taking place, with the hand flat to hold the paper layer, check the packagingdo not squeeze, resistance and no damage to prohibit packages, upside down,with the hand tractor, preventing the paper side drag broken, the inspection method of paper-plastic packaging materials used. After sterilization, pay attention to check the color of color and sealing bag, pay attention to moistureproof preventsharp piercing paper layer. When used to check for any damage, if damagedprohibited the use of.
