To achieve these goals, this utility model provides a kind of mobile blood-collecting carriage plasma freezing device, it is characterized in that including cryogen vessel, PLC, cold-producing medium is filled in described cryogen vessel, described cryogen vessel is provided with lid, blood plasma pallet it is provided with in described cryogen vessel, described blood plasma pallet is provided with compartment, described blood plasma pallet two ends are fixing with described cryogen vessel inwall to be connected, being provided with temperature sensor in described cryogen vessel, described temperature sensor is connected with described PLC.
Described refrigerator container is provided with refrigerant inlet and refrigerant outlet, and described refrigerant inlet is connected by circulation line, circulating pump with described refrigerant outlet.
Described blood plasma pallet is arranged on pallet fixed mount, and described pallet fixed mount is fixing with described cryogen vessel to be connected.
Being provided with liquid level sensor in described cryogen vessel, the height of described liquid level sensor is lower than the height of described compartment, and described liquid level sensor is connected with described PLC, and described PLC is connected with alarm.
Described refrigerant inlet, described refrigerant outlet height lower than the height of described compartment, the height of described compartment is higher than the height of cold-producing medium liquid level.
Ethylene glycol aqueous solution cold-producing medium it is provided with in described cryogen vessel.
The beneficial effects of the utility model are: be provided with compartment, plasma bags is placed on compartment preserve and freezing, both can guarantee that the refrigerating effect of plasma bags, plasma bags it is possible to prevent again directly to contact cold-producing medium, in order to prevent plasma bags from contacting with cryogen further, control liquid level by liquid level sensor and alarm；Additionally, use temperature sensor and PLC to be controlled, it is ensured that the cryogenic temperature of cold-producing medium is accurate, it is to avoid in refrigerating process, refrigerant temperature raises the plasma activities produced and reduces problem；Circulation line is set outside cryogen vessel, it is possible to ensureing whole cryogen vessel homogeneous temperature, the refrigerating effect of plasma bags is good.After this utility model makes flowing blood sampling, blood plasma can be freezing in time, it is ensured that the activity of blood plasma, and temperature controls accurately, and freezing liquid is capable of circulation, it is adaptable to mobile blood-collecting carriage.

Detailed description of the invention
Below in conjunction with accompanying drawing, a kind of detailed description of the invention of utility model is explained.
As shown in Figure 1, this utility model provides a kind of mobile blood-collecting carriage plasma freezing device, it is characterized in that including cryogen vessel 1, PLC 2, fill cold-producing medium in described cryogen vessel 1, in described cryogen vessel 1, be provided with ethylene glycol aqueous solution cold-producing medium.Described cryogen vessel 1 is provided with lid 3, it is provided with blood plasma pallet 4 in described cryogen vessel 1, described blood plasma pallet 4 is provided with compartment 5, described blood plasma pallet 4 two ends are fixing with described cryogen vessel 1 inwall to be connected, being provided with temperature sensor 6 in described cryogen vessel 1, described temperature sensor 6 is connected with described PLC 2.
Described refrigerator container is provided with refrigerant inlet 7 and refrigerant outlet 8, and described refrigerant inlet 7 is connected by circulation line 9, circulating pump 10 with described refrigerant outlet 8.
Described blood plasma pallet 4 is arranged on pallet fixed mount 11, and described pallet fixed mount 11 is fixing with described cryogen vessel 1 sidewall or bottom to be connected, and is pallet fixed mount 11 and the schematic diagram being connected bottom cryogen vessel 1 in figure.
