Technical Field

The utility model relates to a medical instrument, in particular to a temperature control vaccine transfer box.

Background

Vaccines are one of the effective means of disease control. In order to block the spread of infectious diseases, the susceptible people need to be injected with corresponding vaccines in time. The vaccines used for disease control are usually transported and stored at 2-8 ℃, and if the vaccine is inoculated in a country or other non-hospital places, the vaccine is taken out from a cold storage agent insulated cabinet. The ice blocks have low cost, do not need to be purchased, and can be used as cold storage agents. Since the temperature of the ice is often 0 ℃ or less, which results in a temperature in the tank of less than 2 ℃, it is not possible to place the ice directly with the vaccine and requires the use of a specially designed incubator.

Detailed Description

The invention is further described with reference to the drawings and the detailed description.

As shown in figures 1 and 2, the utility model comprises a box body 6 and a box cover 1, wherein the main body parts of the box body 6 and the box cover 1 are made of heat-insulating materials. An interlayer 7 is arranged in the side wall of the box body 6, and the interlayer 7 is used for placing ice cubes. And a channel communicated with each other is arranged between the interlayer 7 and the inner cavity of the box body 6.

The temperature sensing box is characterized in that a temperature sensing box 15 is arranged in the box body 6, an elastic diaphragm 13 is arranged in the middle of the temperature sensing box 15, the temperature sensing box 15 is divided into two cavities, namely a cavity A14 and a cavity B12, through the elastic diaphragm 13, and dimethylamine is arranged in the cavity A14. The cavity B12 is communicated with the interlayer 7 through a pipeline 9. And a cover 5 is arranged at an opening above the interlayer 7, and the edge of the cover 5 can be hermetically connected with the interlayer 7. The cover 5 is provided with a one-way valve 4, the one-way valve 4 is of a spring type structure, and in a natural state, the valve clack 21 is jacked upwards through the spring 11, so that the one-way valve 4 can be closed. Case lid 1 on be equipped with one passageway 2, be equipped with three groups of openings on one passageway 2, the quantity of every group opening is one or more. The number of the first set of openings 19 is the same as the number of the one-way valves 4, and the positions correspond to one another. The first group of openings 19 are provided with a first valve nozzle 20 extending downwards, when the box cover 1 is closed, the first valve nozzle 20 is inserted into the check valve 4, and the valve clack 21 of the check valve 4 is pushed open through the first valve nozzle 20, so that the check valve 4 is opened. The second set of openings 3 is located on the underside of the cover 1.

The box body 6 is provided with a second channel 8, and the second channel 8 comprises an upper end opening 16 and a lower end opening 10. The number and positions of the upper end openings 16 correspond to those of the third group of openings 17 one by one. And a second valve nozzle 18 extending downwards is arranged at the third group of openings 17, and the second valve nozzle 18 is inserted into the upper end opening 16 after the box cover 1 is closed, so that the first channel 2 is communicated with the second channel 8. The lower end opening 10 is positioned on the upper side surface of the lower wall of the box body 6.

In use, the vaccine is placed in the box 6 and the ice is placed in the interlayer 7. During storage, heat is slowly introduced into the box 6 from the lower wall of the box 6 and the box cover 1, and the side wall of the box 6 absorbs heat from the box 6, so that the temperature in the box 6 can be kept approximately balanced. The boiling point of dimethylamine is 7.0 ℃, when the temperature in the box body 6 is higher than 7.0 ℃, the dimethylamine is vaporized, the cavity A14 where the dimethylamine is positioned expands, the space of the cavity B12 is compressed through the elastic diaphragm 13, the air in the cavity B12 enters the interlayer 7 through the pipeline 9, and the cold air in the interlayer 7 enters the box body 6 through the first channel 2 and the second channel 8 respectively, so that the temperature in the box body 6 can be reduced and is lower than 7.0 ℃. When the box cover 1 is opened to carry out the operation of taking and putting vaccines, the one-way valve 4 is closed because the one-way valve nozzle 20 is pulled out of the one-way valve 4, so that the interlayer 7 is in a closed state, thereby preventing cold air in the interlayer 7 from being discharged out of the box body 6 and avoiding the waste of cold energy; after the box cover 1 is closed, the one-way valve 4 is opened, and cold air enters the box body 6 to supplement lost cold for the box body 6 in time, so that the vaccine is kept at a proper low temperature all the time.

It should be noted that while the invention has been described in detail with respect to specific embodiments thereof, it will be apparent to those skilled in the art that various obvious changes can be made therein without departing from the spirit and scope of the invention.
