It is particularly necessary to develop a reasonable and effective blood protection plan during the medical process. At present, autologous blood recovery technology has been widely promoted and applied, that is, from suction from the surgical field to the blood storage tank, to transfusion back into the patient's body after a series of treatments, autologous blood generally needs to be stored in the blood storage tank for 0.5-6 hours. The blood storage tank is usually placed directly indoors. In the case of a long operation, the autologous blood may need to be stored in the blood storage tank for a longer time.
[0003] In order to keep red blood cells in a low-level metabolic state and maintain their normal oxygen-carrying function outside the body, blood needs to be stored at low temperatures.

[0020] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.
[0021] like Figure 1 As shown, a specific embodiment of the utility model provides an autologous blood storage device, which is used for temporary storage of blood during autologous blood collection; specifically, it comprises a blood storage box 100 and a plurality of blood storage bags 200, wherein the blood storage box 100 is provided with a constant temperature chamber 110 for accommodating the blood storage bags 200, and the blood storage box 100 is provided with a constant temperature refrigeration module for adjusting the temperature of the constant temperature chamber 110, and the blood storage bag 200 is provided with an input connector 300, and the input connector 300 is connected to a blood storage blood line 400; the blood storage bag 200 is also provided with a drug liquid connector 500, and the drug liquid connector 500 on each blood storage bag 200 is connected via a first parallel pipeline 600, and the input end of the first parallel pipeline 600 is connected to an anticoagulant syringe 800.
[0022] like Figure 1 As shown, through the above arrangement, the blood storage bag for storing autologous blood in this embodiment can be placed in the constant temperature chamber 110 of the blood storage box 100, and low-temperature constant temperature storage can be achieved through the constant temperature refrigeration module. A corresponding number of blood storage bags 200 can be connected to the blood storage blood line 400 for synchronous blood collection. After the blood collection process is completed, the anticoagulant syringe 800 is connected through the first parallel pipeline 600 to simultaneously inject anticoagulant into each blood storage bag 200, thereby avoiding blood coagulation and improving the convenience of blood collection and storage. In actual applications, the constant temperature refrigeration module can select a semiconductor refrigeration module, which uses semiconductor characteristics to achieve low-temperature refrigeration, and can create a constant temperature storage environment in the constant temperature chamber 110.
[0023] like Figure 1 As shown, since anticoagulants need to be injected into the blood storage bag 200 to prevent blood coagulation, in order to fully mix the blood with the anticoagulant, this embodiment is provided with a placement rack 900 for placing the blood storage bag 200 at the bottom of the constant temperature chamber 110, and a vibration module is provided on the placement rack 900. After each blood storage bag 200 is placed in the constant temperature chamber 110, the placement rack 900 is used to store each blood storage bag, and the placement rack 900 is driven to vibrate by the vibration module to fully mix the anticoagulant with the blood; in actual application, a control panel should be provided on the outside of the blood storage box to facilitate the adjustment of the use parameters and improve the convenience of operation.
[0024] like Figure 1As shown, in order to facilitate medical staff to place or take out the blood storage bag 200, a placement port connected to the constant temperature chamber 110 is provided at the upper end of the blood storage box 100 in this embodiment, and the placement port is provided with a cover plate 1000 that can open and close the placement port. A torsion spring structure is provided on the cover plate 1000, so that the placement port is automatically closed under the action of torsion, thereby improving the convenience of operation. The cover plate 1000 also needs to be provided with a hole structure for various pipelines to pass through.

In addition, an anti-vibration pad 1200 is provided at the lower end of the blood storage box 100. The anti-vibration pad 1200 is used to reduce the vibration of the blood storage box 100.
[0026] like Figure 1 As shown, in order to store blood in multiple blood storage bags 200 at the same time, in this embodiment, a second parallel pipeline 700 that can be connected to the input connector 300 of each blood storage bag 200 is connected to the output end of the blood storage blood circuit 400. After the second parallel pipeline 700 is connected to the input connector 300, each blood storage bag 200 can store blood at the same time, thereby improving the blood storage efficiency; in this embodiment, a negative pressure connector 1300 is also provided on each blood storage bag 200, and the negative pressure connector 1300 can be connected to the negative pressure pipe of the negative pressure module provided in the blood storage box 100. The negative pressure module can maintain negative pressure in the blood storage bag 200, and blood can be automatically input into the blood storage bag 200 under the action of negative pressure. When the negative pressure module is closed, blood collection can be automatically stopped. A stop clamp 1400 is provided on the pipeline connecting the first parallel pipeline 600 of the blood storage bag 200 and the drug solution connector 500 of each blood storage bag 200; when the anticoagulant is added, the pipeline can be closed by the stop clamp 1400 to avoid excessive addition of anticoagulant.
