In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
As shown in fig. 1 to 2, the present invention provides a blood sampling kit for organ transplantation, which comprises a liquid storage structure and a blood sampling structure connected to the liquid outlet structure. Blood can be collected from a donor through the blood collection structure and conveyed to the liquid storage structure for storage.
Specifically, the liquid storage structure may include a flexible liquid storage bag 100, and a liquid inlet structure 400, a liquid outlet structure 500, an air outlet structure 600 and a drug injection port structure respectively disposed on the flexible liquid storage bag 100. Moreover, the blood sampling structure may include a blood sampling device 200, and a flexible blood sampling tube 300 connected to the blood sampling device 200, wherein the flexible blood sampling tube 300 is connected to the liquid inlet structure 400; wherein, the inner diameter of the flexible blood collection tube 300 is not less than 6 mm.
In this way, during the blood sampling process, the hemostix 200 can be used to obtain blood from a donor, and the blood is transferred from the liquid inlet structure 400 to the flexible liquid storage bag 100 through the flexible blood sampling tube 300 for storage; after the blood sampling is completed, a medicine may be injected into the flexible liquid storage bag 100 through the air vent structure 600; during the phlebotomy procedure, the blood supply apparatus may be connected to the fluid outlet arrangement 500 such that the stored blood in the flexible liquid bag 100 is transported to the blood supply apparatus through the fluid outlet arrangement 500. Further, during such exsanguination, the gas in the flexible liquid storage bag 100 may be discharged through the gas outlet structure 600 to increase the exsanguination speed. Moreover, by making the inner diameter of the flexible blood collection tube 300 be greater than or equal to 6mm, a faster blood collection speed can be obtained, hemolysis is not easy to occur, and the problem that the blood collection speed through the artery is too slow and the transplanting time is easily delayed in the traditional technology can be solved; in addition, make the internal diameter of flexible blood collection tube 300 be less than or equal to 15mm, can avoid its internal diameter too big and lead to the blood sampling speed too fast, also can not produce the harmful effects to the donor.
Further, be formed with the stock solution chamber in the above-mentioned flexible stock solution bag, the inner chamber of above-mentioned inlet structure 400, the inner chamber of liquid outlet structure 500, the inner chamber of gas vent structure 600 and the inner chamber of injection mouth structure all communicate with the stock solution chamber. Like this, be convenient for blood flow in the stock solution chamber of flexible stock solution bag 100 through the inner chamber of inlet structure 400, also be convenient for blood flow out the stock solution chamber of flexible stock solution bag 100 from liquid outlet structure 500 outside, also be convenient for the gas in the stock solution chamber of flexible stock solution bag 100 to discharge through gas vent structure 600, also be convenient for add the medicine in the stock solution chamber of flexible stock solution bag 100 through injection mouth structure 600.
Only one of the inlet structure 400 and the outlet structure 500 is in an operating state, which means that blood flows through the inlet structure 400 or the outlet structure 500. When blood is not being drawn, the inlet structure 400 and the outlet structure 500 are both in an idle state, i.e., no blood flows through; during the blood sampling process, blood passes through the liquid inlet structure 400, and no blood passes through the liquid outlet structure 500; conversely, during a blood supply procedure, i.e., when the blood in the flexible liquid storage bag 100 needs to be filled into a blood supply device, blood passes through the liquid outlet structure 500, and no blood passes through the liquid inlet structure 400.
The flexible liquid storage bag 100 is made of a flexible material and is in a shriveled state in an initial state (the flexible liquid storage bag 100 can be shriveled under the action of static electricity or a liquid film on the premise of having flexibility), so that pre-charging is not needed.

During blood collection, the bag structure 120 for storing anticoagulation medium can be squeezed to make the anticoagulation medium enter the blood in the liquid storage cavity for anticoagulation. The amount of anticoagulation medium stored by the capsule structure 120 is related to the capacity of the flexible reservoir 100, generally speaking, the larger the capacity of the flexible reservoir 100, the larger the amount of anticoagulation medium that needs to be stored.
Further, the bag structure 120 may be disposed on an inner wall surface of the liquid storage cavity (i.e., disposed inside the flexible liquid storage bag), and the bag structure 120 may be broken by squeezing, so that the anticoagulation medium stored in the bag structure 120 enters the liquid storage cavity. In addition, the bag structure 120 may also be disposed on the outer wall surface of the liquid storage cavity, and the bag structure 120 may be broken by pressing, so that the anticoagulation medium stored in the bag structure 120 may enter the liquid storage cavity. The anticoagulation medium may be heparin or another substance capable of preventing blood coagulation.
