Definitions
- the present invention relates to a pressure bag used to press a transfusion bag or a blood transfusion bag to inject the liquid in the bag into a patient, and a constant pressure press bag system for keeping the pressure constant.
- the structure of the pressurized bag consists of an outer layer made of a sheet or mesh that does not easily expand and contract, fixed to both ends of an airtight chamber made of a sheet that does not easily expand and contract.
- the infusion bag is put into the created pocket, and the inflation bag is pressed by inflating the pressurized champer by air supply.
- the air supply to the pressurization chamber is performed by a manual rubber ball pump.
- an infusion set is connected to the outlet of the infusion bag, and the opening and closing of the tube is adjusted by a clamp, or a thin tube is incorporated in a part of the infusion tube circuit so as to provide resistance, and the flow rate is generally controlled.
- pressurized bags There are several types of pressurized bags currently in use, ranging from 500 Oml for infusion bags to 300 ml for infusion bags.
- the volume of the pressurized chamber for the smallest 500 ml is about 2 liters, which is about 4 times the volume of the 500 ml infusion bag, causing unnecessary bulk.
- a pressurized bag for 50 Oml is used for an infusion bag of 20 Oral, this ratio becomes about 10 times.

- the infusion bag made of plastic pottle is made in a bottle shape. Due to the bottle shape and plastic properties, conventional single-sided pressing cannot provide sufficient pressure, resulting in the problem of lower discharge pressure from the plastic bottle. A pressurized bag is needed to press the infusion bag made of plastic bottles without lowering the discharge pressure.

If a pressurized bag is used for such an infusion bag and it can be made compact, it can be conveniently used when moving.

Healthcare professionals use this gauge to monitor the pressure in the pressurized chamber and, if the pressure is low, need to maintain the pressure in the pressurized bag by sending air with a manual rubber ball pump. There is a problem that the burden on medical staff is large. Means for solving the problem
