Furthermore, a pull rod 24 is arranged on the outer side wall of the heat preservation box 1, and the pull rod 24 is used for pulling the heat preservation box 1.
Furthermore, wheels 13 are arranged at the bottom of the incubator 1. The operator can conveniently pull the incubator 1.
When the medicine is transported, the heat preservation effect of the heat preservation box can effectively protect and maintain the environmental temperature of the medicine storage box, and when the temperature in the heat preservation box exceeds 8 ℃, the buffer substance with lower temperature in the medicine storage box can further maintain the medicine storage temperature, so that the medicine storage temperature is maintained between 2 ℃ and 8 ℃, and the medicine is prevented from being over-heated; when the temperature in the insulation can is lower than 2 ℃, the buffer substance in the medicine storage box absorbs the low temperature in the insulation can, and the low temperature in the insulation can is buffered to influence the temperature of the medicine stored in the storage box, so that the temperature of the medicine stored is maintained between 2 and 8 ℃, and the medicine is prevented from being over-heated; because the specific heat capacity of the buffer substance in the medicine storage box is large, the temperature of the buffer substance can rise or fall only after the buffer substance absorbs or releases a large amount of energy, the rise or fall of the temperature of the buffer substance can influence the environment temperature for storing the medicines, meanwhile, the heat insulation material on the outer side of the medicine storage box enables the buffer substance to be relatively isolated from the inner environment of the heat insulation box, and the rise or fall amplitude of the temperature of the buffer substance in the medicine storage box along with the change of the inner environment temperature of the heat insulation box is further reduced. Improve the buffering effect of the buffering substance and reduce the temperature difference change of the medicine storage environment. The stability of the temperature of the drug storage environment is improved; when the freezing grids and the reactor are put in or taken out and the endothermic chemical reaction occurs, the temperature in the medicine storage box is ensured not to be excessively higher or lower than the temperature for storing the medicine due to the buffer action of the heat insulation material at the outer side of the medicine storage box and the buffer material in the box body.
When the medicine is transported, the frozen freezing grids can be placed to maintain the low-temperature transportation environment in the heat preservation box, and when the frozen freezing grids can not maintain the low-temperature environment, the freezing medium in the freezing grids flows into the reactor to generate endothermic chemical reaction, so that the low-temperature environment is continuously maintained; or the freezing medium in the freezing grid can directly flow into the reactor to generate endothermic chemical reaction and maintain the low-temperature environment. The freezing grids and the reactors in the heat preservation box can be taken out, an operator can adjust the number of the freezing grids and the reactors in the device according to actual use requirements, and when the chemical refrigeration is carried out, the signal processing system preferentially flows the freezing medium in the freezing grids which is high in temperature or cannot continuously maintain the low-temperature environment into the reactors according to the temperature of each freezing grid sensed by the temperature sensor of the heat preservation box, so that the endothermic chemical reaction is carried out, and the low-temperature environment is maintained.
The used freezing grids and the reactor are updated in time, and then the freezing medium in the replaced freezing grids flows into the reactor to generate endothermic chemical reaction, so that the low-temperature environment can be maintained for a long time. The handle that can stretch out and draw back makes things convenient for the operator to take freezing check and reactor. The signal light may alert the operator to take a used freezer compartment and reactor.
The gravity sensor senses the gravity of the medicine storage box, and the signal processing system can judge the time for taking out the medicine storage box and putting in the medicine to be transported according to the gravity change of the medicine storage box.
The information storage stores all information in the use process, so that the operation is convenient to know whether the whole process of drug loading and transporting is over-temperature, the safety and the quality of the drug are ensured, and the drug taking safety of a subject is ensured.
The wheels at the bottom of the heat preservation box and the pull rods on the side walls facilitate the transfer of the medicine by an operator, and the practicability is high.
