1 There is a problem
The commonly used medical medical plastic bottle material is low density polyethylene (LDPE; PE-FAS-18D022). As the country still lacks a unified quality standard for the quality control of medical plastic bottles, the quality of the products is uneven and extremely unstable. The following aspects are mainly present.
1.1 The bottle's volumetric calibration and medical plastic bottle whose thickness does not conform to the standard is sometimes only 95 ml in the measuring cylinder's operation. The 8 ml eye drop medical medical plastic bottle has not been verified to meet the requirements. Medical medical plastic bottle thickness (by weight) Medical standards: 16.5 g for 200 ml, 9.3 g for 100 ml, 7.0 g for 60 ml, and 2.0 g for 8 ml. We randomly selected some 100 ml samples for comparison and found that the actual weighing of medical medical plastic bottles produced by several factories was only about 7.8 g.
1.2 The use of recycled plastics in factories is not only harmful to human health, but also affects the smoothness and transparency of medical plastic bottles, which in turn affects the quality control of the preparations. For example: affect the clarity of eye drops, etc.
1.3 Medical plastic bottle mouth is not round, and if it is not matched with the lid, filling the drug preparation with this bottle will affect the content of the drug and the preservation time of the preparation.
1.4 Hygiene inspection does not meet the requirements Medical plastic bottles often have serious contamination on the inside and outside walls. There are often impurities in the bottle, such as bugs, broken plastic pieces, and so on. At present, common preparations in many units are filled with medical liquids directly from medical plastic bottles. Since the bottles were not cleaned and disinfected before use, even the freshly prepared preparations did not meet the requirements through hygiene inspection. In our hospital, there has been a failure of hygienic examination of a mixture of belladonna and after analysis, which was caused by the quality of the bottle.
1.5 Outer packaging of medical plastic bottles does not meet requirements Some manufacturers do not double pack medical plastic bottles, and even appear to use direct urea bags.
2 Improvement measures
2.1 Strictly control the purchase of goods In the other conditions are in line with the requirements of the premise, the selection of medical plastic bottles should pay attention to the following points:
2.1.1 Cover lid and bottle mouth should be tight, inside the cover should have a spiral, play inside plug.
2.1.2 The packaging bottle and bottle cap should be packaged together and double outer packaging should be used. In order to achieve dust, moisture, anti-pollution effect.
2.1.3 Leakage test Randomly take the medical plastic bottles produced by various manufacturers, place them in clean water, and gently hold them by hand. Observe whether there is a bubble overflow and whether or not clear water enters. If not, it indicates that the bottle has good sealing performance.
2.2 Strict disinfection medical plastic bottles can be sterilized by the circulation steam method. Experiments confirmed that medical plastic bottles were sterilized by steam at 100°C for 30 minutes. After hygiene tests, pathogenic bacteria, bacteria, and live fleas were all negative and the bottles were not deformed. This method works well, but when sterilizing, it is necessary to pay attention to opening the bottle and the lid must be sterilized at the same time. Medical plastic bottles can also be treated by other methods. If it is swabbed with 75% ethanol or soaked with 0.1% virgin for 30 minutes, rinse with fresh distilled water and drain.
In summary, the author proposes to formulate a unified quality standard for medical plastic bottle packaging. All medical units should strictly control the purchase and disinfection of medical plastic bottles and eliminate the use of inferior products in clinical practice.
