The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

The embodiment provides an infusion bag subassembly with washing function, as shown in fig. 1-3, including infusion bag body 1, infusion bag body 1 is including washing chamber 2 and infusion chamber 3, is equipped with cushion chamber 4 between infusion chamber 3 and washing chamber 2, is equipped with interlayer 5 between infusion chamber 3 and cushion chamber 4. The jagged weak welding rod 6 is arranged between the flushing cavity 2 and the buffer cavity 4, so that the connecting area of the weak welding rod is increased, and the force required for opening the weak welding rod is increased. The interlayer is provided with a T-shaped plastic plug 10, and the rod part of the plastic plug penetrates through the interlayer from the transfusion cavity and extends into the buffer cavity. When the infusion cavity is pressurized, the cover body of the T-shaped plastic plug can further seal the interlayer, and the interlayer can only push the rod part of the plastic plug to be opened from the buffer cavity side. The buffer cavity is filled with proper air which cannot be filled too full and is flat. Flushing liquid is arranged in the flushing cavity 2, liquid medicine is arranged in the infusion cavity 3, sodium chloride injection is arranged in the flushing cavity 2 in the embodiment, and 5% GS can be used for flushing a pipe under special conditions; the infusion cavity 3 is internally provided with sodium chloride injection or glucose injection for normal infusion dosing, and the upper end of the infusion bag body 1 is provided with a dosing part communicated with the infusion cavity 3 for dosing to form liquid medicine required by infusion after dosing. The cushion chamber can play certain guard action to the plastics stopper, because wash before the flush fluid that washes the intracavity is used for the infusion and the washing after the infusion, required flush fluid is more, adopts weak welding rod to keep apart alone, probably because the too much extrusion force of flush fluid causes strutting of weak welding rod greatly easily in the transportation. In the embodiment, the mode of the interlayer and the plastic plug is adopted, and the rod part of the plastic plug is arranged in the buffer cavity, so that the plastic plug is protected to a certain extent, and the possibility that the flushing cavity leaks to the transfusion cavity in the transportation process is reduced.

The lower end of the infusion bag body 1 corresponds to the infusion cavity 3 and the flushing cavity 2 and is respectively provided with an infusion port, the infusion port is respectively connected with a first infusion tube and a second infusion tube, the first infusion tube and the second infusion tube all pass through a press type switch 7, the press type switch 7 can press the first infusion tube to be opened and simultaneously close the second infusion tube, the first infusion tube is pressed and simultaneously open the second infusion tube, and the wrong pipeline can be prevented from being opened.

A connecting plate is arranged between the lower pressing plate 73 and the upper pressing plate 72, clamping columns 75 are arranged on the lower surface of the upper pressing plate 72, the upper surface and the lower surface of the base plate 71 and the upper surface of the lower pressing plate 73, and the clamping columns 75 can clamp and close the first infusion tube and the second infusion tube. The first infusion tube penetrates through the base plate 71 from the upper part, the second infusion tube penetrates through the base plate 71 from the lower part, the upper pressing plate 72 can control the opening and closing of the infusion cavity 3, and the lower pressing plate 73 can control the opening and closing of the flushing cavity 2. The push switch 7 with the structure has a simple structure, and the linkage of the upper pressing plate 72 and the lower pressing plate 73 can be realized by the arrangement of the connecting plate, so that the operation is convenient. To further prevent opening of the wrong tubing, infusion chamber 3 and upper platen 72 are labeled with the same color, e.g., red, and flush chamber 2 and lower platen 73 are labeled with the same color, e.g., green. The connecting openings of the tee joint 8 and the first infusion tube and the second infusion tube are provided with one-way valves 81. The one-way valves belong to the existing products, and the number of the one-way valves is three in the embodiment.
