Problems solved by technology
There are two problems caused by the inactivation of the vaccine: 1. The inactivation of the vaccine is not noticed, so that the vaccinator is exposed to the corresponding disease unconsciously. For vaccines such as rabies and tetanus, it may have serious consequences.
2. The inactivation of the vaccine is equivalent to injecting the corresponding pathogen into the vaccinator, resulting in new diseases

The invention discloses an automatic refrigeration constant-temperature ice bag and a preparation process of the automatic refrigeration constant-temperature ice bag. The automatic refrigeration constant-temperature ice bag comprises an outer bag. An inner bag, a refrigerant and a cold storage agent are arranged in the outer bag. The inner bag is hermetically filled with water. According to the automatic refrigeration constant-temperature ice bag, the inner bag, the refrigerant and the cold storage agent are arranged in the outer bag, after the inner bag is broken, the water in the inner bag flows out and is in sufficient contact with the refrigerant, the temperature can be rapidly reduced, and after cooling, the cold storage agent is further dissolved in a low-temperature solution, so that the gel is formed, the temperature control effect is achieved, and the temperature in the outer bag is kept in the low-temperature state for a long time. The automatic refrigeration constant-temperature ice bag is small in size, light in weight, portable, convenient to use, capable of being taken as a user uses the bag and capable of being provided with different numbers of ice bags according tothe quantity and the volume of the medical biological products. The preparation process of the automatic refrigeration constant-temperature ice bag comprises the steps that the inner bag is filled with the water, and opening sealing is performed; and the inner bag, the refrigerant and the cold storage agent are arranged in the outer bag, and the opening sealing is performed.
Description
technical field [0001] The invention relates to the technical field of cold chain transportation of medical biological products, in particular to an automatic refrigeration constant temperature ice pack and a preparation process thereof. Background technique [0002] Medical cold chain transportation needs to be transported by refrigerated trucks with temperature control 2 - 8°C, and cannot be transported together with fruits and seafood. Companies like SF Cold Chain charge 250 yuan for short-distance transportation within 100 kilometers, and the transportation cost is high. [0003] Some companies with strong strength and large sales volume configure their own refrigerated trucks and transport medical cold chain goods by themselves. Companies with weak strength and low sales volume can neither configure their own refrigerated trucks nor deliver freight to companies like SF Cold Chain. [0004] For short-distance transportation, a foam insulated box can be used, and with ...
