The drug solution inlet (12) is sealed so that gas and liquid do not flow in and out. A connection tube (2) is connected to the outlet (13), and is connected to the hollow container (3) through the tube (3). The material for forming the bag (1) is not particularly limited, but may be polyethylene, polypropylene, polyvinyl chloride, or the like.
It is a synthetic resin such as polyester and ethylene-vinyl acetate copolymer (EVA). The drug solution inlet (12) is generally sealed with a member that can be pierced with a puncture needle.
Since the puncture site is sealed after removal of the puncture needle, a rubber-like elastic plug or cap is preferable. Examples of the rubber-like elastic body include natural rubber, isoprene rubber, butadiene rubber, styrene-butadiene rubber, nitrile rubber, urethane rubber, and silicone rubber.

（１）から薬液が流入するようになっている。The hollow container (3) is made of a rubber-like elastic material such as natural rubber, isoprene rubber, butadiene rubber, styrene-butadiene rubber, nitrile rubber, urethane rubber, silicone rubber, or the like, and has a hollow at both ends. Stop valves (4) and (5) are provided. The check valves (4) and (5) allow only the passage of the chemical solution from the inlet to the outlet of the hollow container (3), and are not particularly limited, but are generally so-called duck bill type or umbrella type check valves. A valve is used. The hollow container (3) has shape retention properties and is generally, but not limited to, formed in an elliptical shape like a rugby ball. Therefore, the hollow container (3) is deformed by the external pressure, the hollow portion is reduced, and the liquid medicine inside flows out through the check valve (5), but when the pressure is released, the hollow container (3) is released. The shape of ()) returns to the original shape, and at this time, the check valve (4) is opened to allow the chemical to flow from the liquid storage bag (1).

のが好ましい。The flow rate control means (6) regulates the upper limit of the chemical solution flow rate, and is arranged upstream of the hollow container (3). Although this is not always necessary, when a highly toxic drug solution, for example, an anticancer drug or the like is injected using the present drug solution injection device, the upper limit of the flow rate is regulated so that a drug solution of an unlimited amount or more is not injected. This is because it takes time to restore the shape of the hollow container (3), and thus it is necessary to lengthen the time interval of the compression. If the time interval is short, the compression is performed during the restoration. As the flow rate restricting means (6), a means for controlling a minute flow rate such as a capillary made of stainless steel or synthetic resin is preferable.

仕様を選択できるようになっている。The pressing means (7) presses the hollow container (3) at a predetermined time interval, and is generally housed in a housing (not shown), and a pair of opposing members sandwiching the hollow container (3) therebetween. Compression plates (8a) and (8b) and driving means (not shown in FIG. 1) for moving the compression plate (8) toward the hollow container (3) to compress the container (3). Consists of The compression plate (8) does not need to be particularly plate-shaped as long as it has a compression surface. Even if both the compression plates (8a) and (8b) are movable, only one of them is movable. Is also good. One of the compression plates (81) shown in FIG. 2 is a part (81a) of the electromagnet (71), and the other is an iron piece (81b). One of the compression plates (82) shown in FIG. 3 is an iron core (82a) of the solenoid (72) (a plate-like member having a compression surface attached to the iron core), and the other is a wall of the housing. (82b). The driving means is not limited to automatic, manual, or manual / automatic switching. Preferably, switching between manual and automatic is possible, and since it is inexpensive and can be assembled in a compact manner, it generally uses electromagnetic force. What was done is adopted. FIG. 2 shows an electromagnet (71), and FIG. 3 shows a solenoid (72). In the figure, (14) and (141) are batteries, (15) and (151) are switches, and (16) and (161) are control means for controlling the operation of the driving means. The control means (16) and (161) control the operation of the driving means, such that the driving means is repeatedly operated by a predetermined program, or a pedigree or the like detected by a sensor (not shown). Thus, the operation of the driving means can be controlled, and the specifications can be selected as needed.
尚、薬液の流量は駆動手段による圧迫板（８）の移動

る。First, a drug solution is injected into the storage bag (1) from the drug solution inlet (12) using a syringe or the like. Next, the driving means of the pressing means (7) is manually operated to introduce the chemical solution in the liquid storage bag (1) into the hollow container (3) (for example, if the button is pressed, the hollow container is pressed to discharge the air therein. When the container is restored to its original shape, the drug solution flows in). Then the connector (11) at the end of the tube with connector (10)
Is connected to an indwelling needle (not shown). After the air in the flow path from the connection tube (2) to the indwelling needle is removed, the indwelling needle is indwelled in the vein of the patient, and if necessary, the driving means is automatically turned on and the desired control method is selected.
