Medical Non-woven cotton with full sterilization packaging materials performance comparison


Medical Non-woven cotton with traditional packaging packing compared with the ideal effect sterilization and bacteria resistance, and lower packaging costs, varying degrees of reduced manpower, material resources, saving health care resources, reduce the risk of hospital infections, the control of hospital infection plays a role, can replace all-cotton reusable medical equipment for the packaging, should be widely applied. sterilization of medical non-woven cotton cloth
resistance bacteria on hospital cost performance
I started in June 2005 and full medical non-woven cotton cloth used for both sterile goods packaging. To determine the medical non-woven packaging materials after sterilization, the current level of the storage period in the hospital environment, to understand the performance difference with cotton packing, hospital sterile supply room for six months of resistance bacteria test results, and make cost, performance comparison.
1 Materials and methods
1.1 Materials
140 by the cotton yarn made of cotton bag double; medical 60g/m2 non-woven layer, a batch of medical devices, self-contained biological indicators agent, a batch of nutrient agar, pulse vacuum sterilizer.
1.2 sample
a group: medical non-woven layer 50cm × 50cm, according to conventional packaging large, each a small curved plate, sandwiching the No. 20 cotton balls, 12cm curved hemostat 1, the pressure tongue plate 1, 14cm dressing tweezers a total of 45 packets. group b: double cotton cloth by the same conventional packaging materials Packaging Act, 45 pack. Placed within each of five self-contained package of biological indicator. Chemical indicator placed within the package, including external chemical indicator tape packet. In line with national health,
1.3 and the effect sterilization of all packages simultaneously detect
pressure steam sterilization, temperature 132 ℃, pressure 0.21mpa. Sterilization end, the self-contained biological indicator with 10 parcels immediately to the microbiology laboratory, biological cultivation, 48h observation sterilization effect.
other parcels stored in the sterile supply room sterile room sterile cabinet. In trials 6 to 12 months, sterile room once a month the number of bacteria in the air is 56 ~ 158cfu/m3, temperature 20 ~ 25 ℃, humidity 35% to 70%, sterile container of the surface cells ≤ 5ccfu/cm sterilization.
1.4 Detection
The a, b group package number, respectively, and 7 days after sterilization, 14 days, 30 days, 60 days, 90 days, 120 days, 150 days, 180 days were randomly selected five of the package, in the microbiology laboratory of samples of biological safety cabinet,MBTシューズ 販売店, into the nutrient agar medium for bacterial culture. Bacterial culture according to Ministry of Health,
2 results
2.1% cotton, medical non-woven bag packaging equipment after sterilization biological culture negative, to the sterilization effect.
2.2 Storage period detection
cotton cloth bag packaging equipment sterile period of 14 days growth, the first 2 months with the growth of bacteria, the end of experiment. Medical Non-woven bag packaging equipment not found within six months of bacterial growth.
2.3 Cost Comparison
a medical non-woven layer to use to size 50cm × 50cm, for example, the price of 2.3 yuan. Cotton cloth 50cm × 50cm double production costs 15.2 yuan, to use 30 times,herve leger sale, for example, cleaning fee for each $ 2. Ignore the human cost and the cost of materials consumed within the package, only use cloth cost more. 3 Discussion
3.1 Comparison of bacterial resistance
experimental medical non-woven fabrics derived bacterial resistance is better than the cotton. Because the arrangement of long and short of medical non-woven fabrics, and other media can make the high-pressure steam bent and show room package penetration, penetration reached 100%,Beats By Dre Studio, with high blocking bacterial barrier, the bacteria penetrate the filter experiments showed that up to 98%. The full transition of cotton bacterial penetration rate of 8% to 30% after repeated washing, ironing, and its fiber structure deformation, resulting in a sparse arrangement of holes, or even the ########## eye is not easy to detect the hole, leading to the failure of bacteria isolated from packaging.
3.2
two packaging costs are one-time cost of packaging materials are different, the cost of long-term storage of sterile packs are very different. The cost of medical non-woven cotton significantly lower than the whole. Also, not listed in the table the whole package again sterile cotton packing date, including the loss of material consumption within the re-processing of water, electricity, gas, detergent and other energy consumption, as well as laundry and supply room staff transportation, cleaning, packaging , the human cost of sterilization, while the consumption of non-medical non-woven fabrics.
3.3 performance comparison
by more than a year of use, we conclude that non-woven cotton cloth, and the difference in performance, compliance and cotton cloth with good benefits, but there are cotton dust pollution and biological barrier the role of bad defects, experiments with bacterial growth and sterile package moist environment, storage conditions of high, short period; and medical non-woven wet conditions did not affect the biological barrier, therefore, sterilization of medical non-woven fabrics with good results and easy to use, a long period of storage,tods shoes outlet, security and other advantages,vibram five fingers outlet, overall better than the full medical non-woven cotton cloth.
medical non-woven cotton with traditional packaging packing compared with the desired effect of sterilization and bacterial resistance, and lower packaging costs, to varying degrees, reducing the risk of hospital infection, hospital infection control play a role can be reused instead of cotton cloth used for the packaging of medical devices, should be widely applied.
