The necessity of a temperature and humidity monitoring system for cold chain vehicles
The supervision of the temperature (humidity) environment in the storage and circulation of pharmaceutical products is the key to ensuring the safety of pharmaceutical storage and transportation. The transportation distance is long and short, and the transportation is changeable during transportation, and the transported food is prone to spoilage. It is inconvenient to stop and check the refrigerated container at any time during transportation, and it is even more inconvenient to open the refrigerated compartment. The quality of transported goods cannot be guaranteed, which affects the reputation of the enterprise and loses market competitiveness.
Application fields of temperature and humidity monitoring system for two cold chain vehicles
(1) Disease control centers, hospitals, blood centers, health and epidemic prevention centers, quarantine and inspection centers across the country
(2) Institutions engaged in research on molecular classification of diseases
(3) National and local disease-related sample bank management organizations and institutions
(4) Various tissue, blood and other sample management laboratories
(5) Laboratory specimen management of scientific research institutes
(6) Cold field vehicles for vegetables and fruits
3. Requirements for cold storage of medicines and vaccines
(1) Refrigerated drugs generally refer to the abbreviation of low-temperature, refrigerated storage drugs. Generally, it refers to medicines kept at a storage temperature of 2-8°C during storage and transportation.
(2) Cold chain drugs generally refer to the entire process from production to use of drugs that require refrigeration. Cold chain drugs require that the specified refrigeration conditions (2-8°C) be maintained during the entire process of storage, transportation and use.
(3) What is a vaccine generally refers to vaccine-like preventive biological products used for human vaccination in order to prevent and control the occurrence and prevalence of infectious diseases.
(4) Vaccine cold chain generally refers to the storage and transportation refrigeration facilities and equipment equipped to ensure the quality of vaccines from the vaccine manufacturer to the vaccination unit during the operation.
