Description

Vaccine Refrigerator

technical field

The utility model relates to a medical refrigerator, in particular to a special refrigerator for vaccines.

Background technique

According to the vaccine storage temperature requirements in the "Standards for Vaccination": 1. Hepatitis B vaccine, BCG vaccine, DPT vaccine, DPT vaccine, JE inactivated vaccine, group A meningococcal vaccine, and A+C group meningococcal vaccine in 2 Transport and store away from light under the condition of ℃～8℃. 2. Polio vaccines, measles vaccines, live attenuated Japanese encephalitis vaccines, and rubella vaccines should be transported and stored away from light at -20°C to 8°C.

At present, most hospitals use household refrigerators to store vaccines, but the design pattern of household refrigerators makes the internal storage space small and it is not convenient for classified storage and labeling of vaccines. In addition, when the door of an ordinary refrigerator is opened, hot air from the outside enters the refrigerating chamber, which causes large temperature fluctuations and reduces the quality of refrigerating.

When major hospitals are inoculated, they often need to open and close the refrigerator frequently, but frequent opening and closing of the refrigerator door will cause the temperature in the refrigerator to be unstable, which may make the vaccine ineffective, especially in summer, when the temperature of the refrigerator is between the frequent opening and closing of the refrigerator door. The temperature in the box fluctuates greatly. In order to avoid frequent opening and closing of the refrigerator door, some vaccines are taken out and placed in the refrigerator, but the refrigerators adopt side-by-side refrigeration, and the temperature in the cabinet is not constant and cannot be marked, which is inconvenient to take.

Detailed ways

Below in conjunction with accompanying drawing and embodiment, further set forth the utility model. In the following detailed description, certain exemplary embodiments of the present invention are described by way of illustration only. Needless to say, those skilled in the art would realize that the described embodiments may be modified in various different ways, all without departing from the spirit and scope of the present invention. Accordingly, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

Please refer to Fig. 1 and Fig. 2, the preferred embodiment of the vaccine special refrigerator of the present invention includes: freezer cabinet 1, refrigerator cabinet 2, partition 3, label 4, freezer door 5, refrigerator door 6. Refrigeration system (not shown), air intake pipe 7, air inlet (not shown), air curtain machine 8, air supply pipe 9, air spray port 10, air outlet 11, exhaust pipe 12, and switch 13.

The freezer cabinet 1 and the refrigerator cabinet 2 are arranged side by side, and the partitions 3 are fixed vertically and horizontally on the left and right side walls of the freezer cabinet 1 and the refrigerator cabinet 2, so that the freezer cabinet The inside of the body 1 and the refrigerating compartment box 2 are respectively divided into several grid-shaped accommodating cavities, and the side of the partition 3 located at the freezing compartment door 5 and the refrigerating compartment door 6 is provided with a label sticking plate. Specifically, the interior of the freezer cabinet 1 and the refrigerator cabinet 2 is divided into a plurality of grids by a partition 3, which is convenient for the classification and storage of vaccines. In addition, a label sticking plate is provided on the side of the partition 3 located at the door of the refrigerator. , easy to paste labels 4, to quickly distinguish and identify vaccines, and quickly find the correct vaccine when taking it.

The freezer door 5 and the refrigerator door 6 are respectively arranged at the front of the freezer cabinet 1 and the refrigerator cabinet 2, and the refrigeration system is arranged at the rear of the freezer cabinet 1, and mainly provides cold air and cooling for the inside of the refrigerator. Circulate cool air. The air inlet is arranged at the rear of the freezer cabinet 1 , and one end of the air inlet pipe 7 communicates with the air inlet, and the other end communicates with the air supply pipe 9 . The air supply pipeline 9 extends from the rear of the refrigerating room box 2 from above the refrigerating room box 2 to the front of the refrigerating room box 2. In the front, the air supply pipeline 9 communicates with the refrigerator compartment box body 2 through the air outlet 10 . The air curtain machine 8 is arranged in the air supply pipeline 9 and is located at the upper rear of the refrigerator box body 2, the air outlet 11 is arranged at the rear of the refrigerator box body 2, and the exhaust pipe 12 is arranged at the refrigerator box body 2. The rear of the room box body 2 communicates with the air supply duct 9 through the air outlet 11 . This design is mainly to draw the cold air from the freezer box 1 through the air curtain machine 8 and send it to the refrigerator box 2, and finally pass through the strip-shaped narrow slit on the top wall in front of the refrigerator box 2. The air outlet 10 ejects one deck of air curtain downwards.

The switch 13 is arranged on the front part of the refrigerator box 2 and cooperates with the refrigerator door 6 , and the switch 13 is electrically connected with the air curtain machine 8 for controlling the opening and closing of the air curtain machine 8 . Specifically, the switch 13 is arranged on the housing at the front of the refrigerator compartment 2 and is located on the side where the refrigerator compartment door 6 is pivotally connected with the refrigerator compartment compartment 2. When the refrigerator compartment door 6 is closed, it is connected to the The switch 13 is in conflict with each other, so that the switch 13 is closed, and the air curtain machine 8 is powered off; power ups.

Wherein, the cross-sectional area of the air supply duct 9 gradually decreases from the rear of the refrigerator compartment 2 to the front of the refrigerator compartment 2 . The air curtain machine 8 is a transverse airflow fan. The length of the transverse airflow fan is the same as the width of the refrigerator compartment box 2 .

Please continue to refer to Figure 1 and Figure 2. When in use, when the refrigerator door 6 is opened, the switch is turned on to start the air curtain machine 8, and then a suction force is generated at the rear of the air curtain machine 8 to pull the freezer compartment The cold air in 1 is sucked in the air supply duct 9 through the air inlet and the air intake duct 7, and at the same time, the air in the refrigerator compartment casing 2 is also sucked into the air supply duct 9 through the air outlet 11 and the exhaust duct 12, and then The cold air is blown to the air outlet 10 through the air curtain machine 8, and under the action of the gradually decreasing air supply pipe 9 and the strip-shaped air outlet 10, the cold air is ejected downward to form an air curtain. Because the connection between the air outlet 10 and the air supply pipe 9 is set as a circular arc transition, the formed air curtain is in an "L" shape, and the gas will enter the refrigerator cabinet 2 again, and at this time enter the refrigerator cabinet 2 air enters the air supply duct 9 through the air outlet 11 and the exhaust duct 12, and circulates through the air curtain machine 8 again. Due to the formation of the air curtain, the cold air in the refrigerator compartment 2 will not flow to the outside, and the hot air outside will not enter the refrigerator compartment 2, thus avoiding the frequent opening and closing of the refrigerator compartment door 6 and affecting storage in the refrigerator. The preservation of the vaccine inside the chamber casing 2.

The above specific description of the utility model is intended to illustrate the implementation of the specific embodiment, and should not be understood as a limitation of the utility model. Those skilled in the art can make a decision on the basis of the detailed implementation under the teaching of the utility model. Various variants should be included in the concept of the present utility model. The scope of protection required by the utility model is only limited by the claims.
