Description

Technical Field

[0001] The present invention relates to the technical field of blood collection, and in particular to a storage device for blood transportation. Background Art

[0002] Currently in the field of blood collection and transfusion, unnecessary blood components such as white blood cells are removed by filtering, especially for whole blood, red blood cell suspension and platelets, and the filtrate is collected to achieve the storage or application of blood components. This blood is usually stored in a medical blood storage bag. When blood is needed, the puncture needle of the transfusion device is inserted into the blood storage bag, so that the blood storage bag can directly supply blood to the patient.

[0003] When existing blood bags are transported in batches, they are generally stacked in a container. The blood bags at the bottom will be subjected to considerable pressure. In addition, during transportation, the car will be bumpy. Due to the influence of gravity acceleration, the blood bags at the bottom will be subjected to greater pressure and are prone to explosion. Therefore, corresponding improvements are made to address this problem. Summary of the invention

[0004] Based on the technical problems existing in the prior art, the present invention proposes a storage device for blood transfer.

[0006] Preferably, an inflation tube is provided at one end of the air bag, and a third tube cover is threadedly connected to the inflation tube. After opening the third tube cover, gas is filled into the air bag through the inflation tube to keep the air bag in a certain expansion state, and then the third tube cover is tightened onto the inflation tube to conveniently complete the inflation of the air bag.

[0007] Preferably, a pair of symmetrically distributed L-shaped clips are fixed to the bottom of the airbag, and a pair of clip sleeves for fixing the clips are fixed to the surface of the bag body. When the airbag is not inflated, the two clips under the airbag are respectively connected to the two clip sleeves. After the airbag is inflated, the shape of the airbag is relatively fixed, so the clips will not detach from the clip sleeves, thereby achieving fixed installation of the airbag.

[0025] Furthermore, a pair of symmetrically distributed L-shaped clips 13 are fixed to the bottom of the airbag 6, and a pair of clip sleeves 14 for fixing the clips 13 are fixed to the surface of the bag body 1. When the airbag 6 is not inflated, the two clips 13 below the airbag 6 are respectively connected to the two clip sleeves 14. After the airbag 6 is inflated, since the shape of the airbag 6 is relatively fixed, the clips 13 will not detach from the clip sleeves 14, thereby achieving fixed installation of the airbag 6.

When the airbag 8 is deformed, it will drive the second push plate 24 to move, and then the second push plate 24 will synchronously drive the rack 25 to move, and then the rack 25 will mesh with the gear 23 to drive the shaft column 22 and the stirring frame 16 to rotate.

[0029] Furthermore, a rubber sealing sheet 26 for inserting a needle is fixed at the tube opening of the blood transfusion tube 2. When performing a blood transfusion on a patient, the needle only needs to be inserted into the rubber sealing sheet 26.
