The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
The invention is further described with reference to the following figures and specific examples.
As shown in fig. 1 and fig. 2, a blood transfusion pressurizing device of the present embodiment includes a pressurizing bag 1, a hollow air bag 3 is disposed on a side wall of the pressurizing bag 1, the pressurizing bag 1 is used for placing a blood transfusion bag, the blood transfusion bag is connected with a blood transfusion tube during blood transfusion, a tube hole 2 for passing the blood transfusion tube is disposed at a lower end of the pressurizing bag 1, and a fixing strap 4 is disposed at an upper end opening of the pressurizing bag 1; specifically, the upper end both sides of pressurization bag 1 all are equipped with fixed band 4, and fixed band 4 can be tied together to blood transfusion bag from the upper end roll-off when preventing 3 expansions of gasbag, guarantee that gasbag 3 can effectual extrusion blood transfusion bag, pressurize the blood transfusion bag, realize the pressurization blood transfusion.
Grooves are arranged at two sides of the inner wall of the pressurizing bag 1 at intervals from top to bottom, and heating strips 5 are arranged in the grooves; the height of the heating strips 5 is equal to the distance between the two heating strips 5, and the heating strips 5 on one side and the heating strips 5 on the other side of the inner wall of the pressurizing bag 1 are arranged in a staggered mode. As shown in figure 1, the heating strips on the inner wall of the left side of the pressurizing bag 1 and the heating strips on the inner wall of the right side of the pressurizing bag 1 are arranged in a staggered mode, when the air bag 3 expands, the inner wall of the pressurizing bag 1 is in contact with the blood transfusion bag, the blood transfusion bag can be guaranteed to be in contact with the heating strips from top to bottom, and heating uniformity is guaranteed. Meanwhile, the heating strips arranged at intervals up and down enable the air bag wall between the two heating strips to be expanded to effectively extrude the blood transfusion bag, and compared with the arrangement that the inner wall of the pressurizing bag 1 is provided with the heating layers, the air bag has a better pressurizing effect on the blood transfusion bag, and the heating uniformity is not influenced.
