Embodiment 1

[0032] The utility model relates to a blood coagulation factor plasma quick-freezing refrigerator, which is used for quick freezing and storage of blood coagulation factor plasma products. Such as Figure 1-6 As shown, the blood coagulation factor plasma quick-freezing refrigerator includes a refrigerator body 1 and at least one refrigeration unit 10 for increasing the freezing capacity. The refrigerating unit 10 is the core component of the quick-freezing refrigerator, and is arranged inside the refrigerator body 1 . For a single refrigerating unit 10 , it includes a cold storage door 2 , a quick-freezing plate 5 , a fan system 7 and an evaporator 9 . The quick-freezing plate 5, evaporator 9, compressor 25, and condenser of the refrigerating unit 10 form a refrigerant circuit to complete the refrigeration cycle, so as to realize the cooling of the quick-freezing refrigerator and the quick-freezing of blood coagulation factor plasma products. For ease of description, the sid...

Embodiment 2

[0039] In this embodiment, its basic structure, principle and technical effect are the same as those in Embodiment 1. For brief description, for parts not mentioned in this embodiment, reference may be made to the corresponding content in Embodiment 1. Since the quick-freezing refrigerator of the present invention has a relatively large volume, it is necessary to grasp the operating conditions of the refrigeration unit 10 conveniently and in time. The quick-freezing cold storage of the present invention adopts fuzzy PID control. Specifically, the set value of PID can be controlled according to the time required for quick freezing, so that the quick freezing requirements can be realized conveniently and flexibly. The PID temperature feedback can select the temperature of any refrigeration unit 10, or select the average temperature of multiple refrigeration units 10, so as to ensure the uniform distribution of the temperature of the entire quick-freezing refrigerator. The coag...

Abstract

The invention provides a blood coagulation factor type plasma quick-freezing cold storage which comprises a cold storage body and at least one refrigerating unit, each refrigerating unit comprises a cold storage door, quick-freezing flat plates, a fan system, an evaporator and shielding parts, the cold storage door is arranged on the front side of the refrigerating unit, one side of the cold storage door is the shielding part, and the other side of the cold storage door is the external environment. Each shielding part comprises an inner door and a connecting plate. The quick-freezing flat plates are fixed to the supporting frame and are arranged in multiple layers, and a gap is formed between every two adjacent quick-freezing flat plates to form a containing space. The shielding parts are used for sealing the containing spaces corresponding to the quick-freezing flat plates, and the interior of the refrigerating unit is divided into a plurality of independent sealed containing spaces. When the cold storage door is opened to take plasma products, only the corresponding shielding part on a certain layer needs to be opened, leakage of most cold air is avoided, more accurate temperature control is facilitated, temperature fluctuation is reduced, and quick freezing and activity of stored blood coagulation factor plasma are facilitated.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a blood coagulation factor plasma quick-freezing refrigerator. Background technique [0002] Plasma quick-freezing cold storage is one of the necessary equipment for blood banks and blood centers in major cities. When clinical blood transfusion is performed in various hospitals, in order to ensure the quality of plasma, it is required to separate plasma from whole blood within 6 to 8 hours after blood collection. Quick freeze into blocks at low temperature. In addition, blood coagulation factor products need to maintain their activity requirements, and the collected plasma needs to be frozen quickly. GMP requires that the center of the plasma should be frozen within 60 minutes. However, at present, most quick-freezing refrigerators freeze slowly and have small freezing capacity, which cannot meet the needs of large-scale use. During the frequent use of the quick-freezing ...
