Embodiment Construction

[0021] Attached below Figures 1 to 5 The present invention is described in detail.

[0022] Such as Figure 1 to Figure 3 As shown, a contact type low-temperature quick-freezing box includes a box body 9, a refrigeration unit 7, a cold storage plate 3, and a power unit. The refrigerating unit 7 includes an evaporator, the evaporator is fixed with the cold storage plate 3, and the evaporator plays the role of reducing the temperature of the cold storage plate 3, and the upper plate 1 and the lower plate 2 are arranged on the box body 9, and the cold storage plate 3 is embedded on the upper plate 1 and the lower plate 2, one end of the upper plate 1 and the box body 9 pass through the first hinge 6, and the lower plate 2 provides a plane for placing the blood plasma bag 8. An elastic support assembly 4 is arranged below the lower plate 2; the power device includes an opening and closing device that drives the upper plate 1 to open and close, and the upper plate 1 presses the ...

Abstract

The invention relates to a contact type low temperature quick-freezing box. The contact type low temperature quick-freezing box comprises a box body, a refrigerating unit, a cold storage plate and a power device. The refrigerating unit comprises an evaporator which is fixed to the cold storage plate; the box body is provided with an upper plate and a lower plate, the cold storage plate is embedded into the upper plate and the lower plate, and one end of the upper plate is hinged to the box body; the power device comprises an opening-closing device for enabling the upper plate to perform opening-closing motion and an elastic supporting assembly for enabling the lower plate to perform up-and-down motion. According to the contact type low temperature quick-freezing box, the distance between the upper plate and the lower plate can be adjusted, and freezing of plasma bags with different specifications can be achieved; the contact areas between the plasma bags and the upper plate and between the plasma bags and the lower plate are large, and the freezing speed of the plasma bags can be increased; the upper plate and the lower plate jointly extrude the plasma bags, and obtained frozen plasmas are regular in shape and easy to store.

Description

technical field [0001] The invention relates to a low-temperature quick-freezing box, in particular to a low-temperature quick-freezing box for fast freezing of blood plasma, which has fast freezing speed and regular shape of plasma block. Background technique [0002] An important way of medical treatment during clinical blood transfusion. With the diversification and advancement of medical methods, the method of blood transfusion has gradually developed from the previous method of transfusion of whole blood to the method of transfusion of blood components according to the needs of patients. The main way to improve the safety and economy of blood use when blood components are transfused. In order to ensure the quality of plasma, it is required that the plasma must be separated from whole blood within 6 to 8 hours after blood collection and quickly frozen into blocks at low temperature. [0003] Plasma quick freezing machine is an important equipment to ensure the quality ...
