Description
Technical field
A kind of transport case is the utility model is related to, especially a kind of vacuum constant temperature transport case, belongs to transport field.
Background technology
At present, when biological sample, vaccine, blood and valuable biochemical reagents are transported and transported, typically using past
Ice cube, dry ice or ice bag etc. are directly added into transport case, to ensure that sample or reagent are always held at 0~10 in transportation
DEG C low temperature environment in, play refrigeration corrosion-resistant effect.On the contrary, to the biological sample of such as blood platelet etc, its storage temperature
Control is then needed at 20~24 DEG C.But also incomplete logistics condition at present is limited to, transhipment time is relative in long-distance transport
Longer, particularly during the broiling summer, ice cube is easy to melt, and dry ice is by heat sublimation so that the storage temperature of sample rises rapidly
Height, bacterium amount reproduction is ultimately resulted in, causes sample to rot, the serious consequence such as reagent inactivation failure.
Therefore, be currently badly in need of a kind of structure is novel, be easy to carry, can long-time storage constant temperature transport case.
The content of the invention
In order to solve above-mentioned prior art problem, the utility model aims to provide a kind of for biological sample, medical treatment production
Product and the portable bilayer vacuum constant temperature transport case of valuable biochemical reagents long-distance transport.
The technical solution of the utility model is as follows：
A kind of vacuum constant temperature transport case, including casing and the case lid on casing, it is characterised in that：The case
Body includes shell, first layer and the second layer on the inside of shell, is sealing vacuum layer, the second layer between first layer and the second layer
Storage space is formed, the storage space is in communication with the outside by the passage on casing, and the passage is located on the downside of casing,
Passage side is provided with extraction valve, and extraction valve is provided with plug and the first screw capping；Case lid is provided with vacuum meter and passage, passage
It is provided with the second screw capping.Before taking thing, the ventilation of the second screw capping is first turned on.
Further, the extraction valve is check valve, and plug is sheathed in check-valve port, and screw capping is tightened in check-valve port
On, after being vacuumized by check valve, top cement plug is covered, screws on screw capping sealing.
Further, handle is additionally provided with the middle part of the case lid, the handle is located in groove.
Further, rubber gasket, thickness 0.2-1cm are provided with the top of described casing first layer.
Further, the internal diameter of described passage and passage is 0.5-1cm.
Further, first layer and the second layer are low thermal conductivity material, seal and take out between the casing second layer and first layer
It is vacuum formed sealing vacuum layer.Double-layer vacuum pumping reaches constant temperature effect.
Compared with prior art, the utility model has the following advantages that：
（1）The utility model can be according to the difference of transport sample, from the temperature source of different proportion, with sample to be transported
After being together put into storagetank, by vacuumize process, the oxygen in transport case is extracted, and this causes the microorganism in case to lose
" living environment " depended on for existence has been gone, has been effectively prevented that sample is contaminated, occurs to go rotten, be rotten；
（2）Because PU expanded materials thermal conductivity factor is relatively low used in the first layer and the second layer of casing, have high
Thermal insulation, the sealing vacuum layer between two layers avoid heat transfer and convection current so that temperature source due to lacking transmission medium
Temperature changing speed is extremely slow, and the temperature in prolonged transportation in transport case will not also vary widely, and keeps permanent
Temperature state, further effectively reduce sample and rotten possibility occurs, ensure that the reliability of transhipment dispatching.
（3）For traditional pulling buckle type transport case poor sealing, the shortcomings of easy gas leakage, the utility model casing top
The rubber gasket of inner ring design can be very good solve this problem, and good sealing is maintained after vacuumizing.
（4）The utility model simple structure, low manufacture cost, vibration resistance impact resistance, and it is easy to carry.
