Human vaccine freezer

Abstract

The invention relates to the technical field of human vaccines, in particular to a human vaccine freezer comprising a cylinder, a sealing mechanism, a temperature detection mechanism, an ejection mechanism, a refrigeration mechanism and vaccine bottle bodies; according to the human vaccine freezer, external temperature can be measured through a thermistor; when the temperature rises, the resistance increases, and a pointer of an ohmmeter moves; a fountain pen is moved along with a supporting rod, and the movement path of the fountain pen is drawn on a scale whiteboard; when the temperature falls, the resistance decreases, and the fountain pen is driven by a rotating disk to rotate reversely, so that the measurement of environment temperature is achieved; medical staff can judge whether cold chains are disconnected and the activity of vaccines is normal in the transportation process of the vaccines according to the movement path of the fountain pen in use; deactivated vaccines are prevented from being used by the medical staff effectively, and the safety of the vaccines is ensured; vaccine bottles are placed in placement grooves, and the temperature difference in the cylinder is reduced effectively; and when the medical staff use the vaccine bottles at an upper layer, the cold storage of the vaccine bottles at a lower layer is not affected.

Description

technical field [0001] The invention relates to the technical field of human vaccines, in particular to a refrigerator for human vaccines. Background technique [0002] Vaccines are a special class of medicines. They contain artificially processed pathogen components, which not only retain their characteristics that can be recognized by the immune system, but also destroy their lethality; as biological products, vaccines are relatively sensitive to temperature. High or too low will affect them; from vaccine production to vaccination, it has to go through multiple circulation, transportation and storage links. In order to ensure the stability and antigenicity of the vaccine, the whole cold chain is particularly important; generally It is said that vaccines need to be stored below 8°C. In order to ensure low temperature, a lot of professional equipment should be equipped in the transportation and storage of vaccines. [0003] However, due to many human factors and equipment f...

Problems solved by technology

[0003] However, due to many human factors and equipment factors in the vaccine transportation process, once a loophole in a certain link causes the cold chain to be interrupted, the vaccine will be overheated and inactivated, and the medical staff who use it cannot know whether the vaccine is inactivated. Injecting the inactivated vaccine into the human body will cause very serious consequences; and when the vaccine is taken later, the airtight door will be opened, and the cold air will quickly escape, causing the temperature inside the storage box to rise, causing certain damage to the vaccine. impact, and it is inconvenient to take; in view of this, the invention provides a kind of human vaccine refrigerator, which has the following characteristics:
