Medicine cold chain incubator no longer worry about "supercooling"

Abstract: some citizens buy drugs that need to be "refrigerated" or "shady" for preservation, and habitually put them in refrigerators or boxes with ice boxes. Even in the pharmaceutical logistics and cold chain express industry, when packaging drugs that need to be refrigerated, they also directly store the cold storage agents just taken out of the refrigerator freezer around the drugs in the incubator, which is not only possible. Lead to drug failure, but also endanger the health and safety of patients.

I. common fault of cold chain packaging of Medicine: "supercooling"

Some people put drugs that need to be "refrigerated" or "in the shade" in refrigerators or in boxes with ice boxes, so that they can be safely stored, but it is not safe. Generally, the storage environment of drugs is determined according to the storage conditions in the instructions. "Normal temperature" generally refers to 10 ℃ ~ 30 ℃, "cool" refers to below 20 ℃, "cold storage" refers to 2 ℃ ~ 8 ℃. Generally speaking, it may only meet the requirements of "cold storage" when the medicine is placed in the refrigerator, but some medicine bottles with multiple doses and needs to be used for many times are easy to grow bacteria after opening. The storage in the refrigerator not only affects the quality of the medicine, but also pollutes the food. It is recommended to put the medicine in a special medical refrigerator or cold bag.

So, how should medical refrigerators store drugs with temperature requirements? People who have been exposed to the cold chain packaging of medicine know that such medicine is generally packed in medical refrigerated boxes or other forms of heat preservation boxes stacked with cold storage agents, among which, the cold storage agents are generally in the form of ice bags or ice boxes, and different types of cold storage agents are selected for different temperature ranges. Take "cold storage" as an example. First, pre cool the drug refrigerator to 2 ℃ ~ 8 ℃, take a certain amount of frozen refrigerant and place it in the environment of 2 ℃ ~ 8 ℃ to release the excess "cold capacity" and return it to the temperature of 2 ℃ ~ 8 ℃, finally take the drug out of the original storage temperature and put it into the refrigerator, stack a certain amount of refrigerant around, and immediately seal the container. The process takes more than 2 hours, so the efficiency is low. This batch is impossible for pharmaceutical cold chain packaging.

Some people have misunderstandings about refrigerated packaging. They think that the colder the medicine, the less likely it is to go bad, the colder it is, the better it is. Some even put the medicine directly in the refrigerator no matter what temperature it needs. Or as mentioned above, some pharmaceutical logistics and cold chain express industries directly store the cold storage just taken out of the refrigerator freezer around the medicine in the incubator when packaging the medicine to be refrigerated. Agent. In this regard, we must make it clear that different drugs should be stored in strict accordance with different temperature requirements. Not only can the temperature be too high, but also the temperature is too low to make the drugs "supercooled". If some biological agents are stored in too low temperature, not only the efficacy is damaged or frozen, but also the health and safety of patients will be endangered. The common problem of cold chain packaging in medicine is "supercooling".

II. Analysis of the causes of the problem of "supercooled" cold chain packaging

This paper analyzes the causes of "supercooled" cold chain packaging. In addition to the wrong concept of "the colder the better", another important reason is that there is no effective technical means to prevent "supercooled" packaging.

Still take "cold storage" as an example. Why don't some pharmaceutical logistics and cold chain express industries strictly abide by packaging specifications when packaging drugs that need to be refrigerated? Haven't they received relevant training? The answer is No. The steps of "refrigerated" packaging seem simple, but in practice, each step will take tens of minutes or even hours. Usually, the staff of pharmaceutical logistics and cold chain express need to face a large number of drugs that need to be loaded and transported instead of one box or two boxes. Because there is no effective technical means to prevent "supercooled" packaging, the time-consuming and "cumbersome" cold chain packaging steps are enormous. Suddenly "force" them to take risks and do not operate in accordance with the regulations. The most common way is to put the medicine in the cold chain box, and directly pile up the cryogen with the temperature of minus 10 degrees or even dozens of degrees around! Is there any way to simplify this "cumbersome" packaging process, so that non professionals can easily be competent for cold chain packaging, and ensure that drugs with cold storage needs can be safely used in patients? Suzhou ante Industry Co., Ltd. as a cold chain packaging enterprise, in line with the sense of responsibility to the society and the pharmaceutical industry, assiduously studied and innovated, invented the cold chain box for freeze protection of refrigerated drugs.
