Embodiment Construction
[0044] Hereinafter, the best form of implementation of the present invention will be described in detail with reference to the accompanying drawings. The pressurized chamber and the outer layer are made in the same way unless there is a special reason, and the sizes of various pressurized bags vary according to the size of the infusion bag used.
[0045] Figure 1-a~Figure 1-d is a first embodiment of the pressurized pack of a pressurized chamber of the present invention, Figure 1-a is the front view of the pressurized chamber 2, Figure 1-b is the front view of outer layer 3, Figure 1-c It is the pressurized bag 1 seen from the cross-sectional view of the line A-A' of the outer layer 3, and the fixing part 22 of the pressurized chamber 2 is fixed on the outer layer 3. Figure 1-d It is a cross-sectional view seen from the line A-A' of the outer layer 3 when the infusion bags 40, 41 are placed on both sides C and D of the pressurized chamber 2 of the pressurized pack 1 an...

Pressing bag and constant-pressure pressing bag system are characterized in that, the pressure bag includes: a pressing chamber adapted to be inflated by air-feeding; and a rectangular outer layer having such length as to surround the pressing chamber. Fasteners are formed on one end side of a front surface and the other end side of a back surface of shorter sides of the outer layer. The pressing chamber is fixed to the outer layer in the axial direction. In use, infusion bags are surrounded by the outer layer in a manner contacting with the pressing chamber and fastened by the fasteners. The prevention has effects of: the pressing bag formed by using the rectangular outer layer to surround the pressing chamber and infusion bags feeds the pressing chamber with air for inflation, the inflated volume of the inflated pressing chamber can be limited within a necessary minimum range for pressure applying in virtue of the pressing chamber being limited in the surrounded space by outer layer, thus a pressing bag with reduced inflation volume and gas saving is provided. Furthermore, the pressing gas is constant-pressure adjusted, the pressing bag is fed with gas by a gas feeding device from the pressing chamber which provides a constant-pressure pressing bag system saving gas.
Description
technical field [0001] The present invention relates to a pressurizing pack used for compressing transfusion bags or blood transfusion bags etc. to be injected into a patient's body and a constant pressure pressurizing pack system for maintaining constant pressure. Background technique [0002] The compression pack is constructed as follows. An outer layer made of a hard-to-stretch resin film or mesh film is fixed at both ends of a sealed pressurized chamber made of a hard-to-stretch resin film, between the pressurized chamber and the outer layer. Fill the infusion bag in the formed pocket bag, send air to the pressurized chamber to make it expand and compress the infusion bag, and the air supply to the pressurized chamber is carried out by utilizing a manual rubber ball pump. The outlet of the infusion bag is connected to the infusion tube set, and the opening and closing of the infusion tube is adjusted by the clip, or a part of the infusion tube circuit is formed by a thi...
