Abstract
Description
Technical Field
[0001] The utility model relates to a blood product storage room. Background Art
[0002] The collected blood has strict requirements for the storage environment temperature, and different blood products have different requirements for the storage temperature range. For example, plasma needs to be stored below -18°C, red blood cells need to be stored within 2-6°C, and platelets need to be stored within 20-24°C.
[0003] In blood product storage places, such as central blood stations, air-conditioning environments, refrigerators and freezers are currently used to store different blood products. These storage methods generally have the disadvantages of small space, slow cooling and easy frost formation; on the other hand, due to the need to frequently open and close refrigerators and freezers, the storage environment loses a lot of cold and the temperature fluctuates greatly, affecting the quality of blood products.
[0004] The cold storage system that uses refrigeration units to provide cooling can solve the above problems. However, under normal circumstances, the total cooling capacity of a blood station is not large, and the cooling capacity of the refrigeration units provided for various blood products is even smaller. Therefore, the use of ordinary cold storage systems generally has the problems of large space occupation, large equipment investment and high maintenance costs. In addition, due to the large storage temperature gradient of different blood products, there are many technical obstacles to using a set of refrigeration units to provide multiple temperature environments, mainly including the difficulty of control and the high failure rate of the unit.

Specifically, there is a first partition wall 7 between the plasma storage chamber 5 and the centralized cooling chamber 8, a second partition wall 10 between the centralized cooling chamber 8 and the red blood cell storage chamber 12, and a third partition wall 14 between the red blood cell storage chamber 12 and the platelet storage chamber 15.
[0022] The evaporator 9 is installed in the centralized cooling room 8 and connected to the refrigeration unit through the cooling pipe 3 and the cooling return pipe 25. The cooling pipe 3 is used to supply the refrigerant medium to the evaporator 9, and the cooling return pipe 25 is used as a pipe for the refrigerant medium to return to the refrigeration unit. Specifically, the refrigeration unit includes a main refrigeration unit 1 and a standby refrigeration unit 2, and the refrigerant medium outlet ends of the main refrigeration unit 1 and the standby refrigeration unit 2 are respectively connected to the cooling pipe 3 through pipelines, and the refrigerant medium return ends of the main refrigeration unit 1 and the standby refrigeration unit 2 are respectively connected to the cooling return pipe 25 through pipelines.
[0023] The first partition wall 7 is provided with a first air supply duct 27 for delivering cold air in the centralized cooling room 8 to the plasma storage room 5. The first air supply duct 27 is provided with a first fan 4 and a first damper 27-1, the latter being used to adjust the ventilation volume. The first partition wall 7 is also provided with a first return air duct 6 connecting the centralized cooling room 8 and the plasma storage room 5. The first return air duct 6 is provided with a fourth damper 6-1, the latter being used to adjust the ventilation volume.
[0024] The second partition wall 10 is provided with a second air supply duct 28 for delivering cold air in the centralized cooling room 8 to the red blood cell storage room 12. The second air supply duct 28 is provided with a second fan 16 and a second damper 28-1, the latter being used to adjust the ventilation volume. The second partition wall 10 is also provided with a second air return duct 11 connecting the centralized cooling room 8 and the red blood cell storage room 12. The second air return duct 11 is provided with a fifth damper 11-1, the latter being used to adjust the ventilation volume.
[0025] The second partition wall 10 is also provided with a third air supply duct 17 for delivering cold air in the centralized cooling room 8 to the platelet storage room 15, and the third air supply duct 17 passes through the third partition wall 14. The third air supply duct 17 is provided with a third fan 19 and a third damper 17-1, the latter being used to adjust the ventilation volume. The second partition wall 10 is also provided with a third return air duct 13 for connecting the centralized cooling room 8 and the platelet storage room 15, and the third return air duct 13 passes through the third partition wall 14. The third return air duct 13 is provided with a sixth damper 13-1, the latter being used to adjust the ventilation volume.
[0026] When in use, the evaporator 9 reduces the ambient temperature in the centralized cold supply room 8 to below -18°C. The first fan 4 sends cold air into the plasma storage room 5 and ensures that the ambient temperature in the plasma storage room 5 is suitable for preserving plasma products by adjusting the first damper 27-1 and the fourth damper 6-1.

The main purpose of the red blood cell chamber heater 18 and the platelet chamber heater 20 is to provide thermal energy compensation when the atmospheric temperature is too low. Specifically, the red blood cell chamber heater 18 and the platelet chamber heater 20 are both in the form of heat exchangers, and the tube side of the heat exchanger is water, and the shell side is the storage chamber.
