The operation of flushing the cell preparation bag will undoubtedly increase the operational difficulty and operational risk.
Disclosure of Invention
The utility model aims at providing a disposable cell preparation bag can realize directly supplementing normal saline through connecting pipe and input syringe needle in the cell preparation bag use to the inside, avoids the cell extravagant, avoids directly carrying out the operation degree of difficulty and the operational risk that brings when dashing to annotating to wash the cell preparation bag simultaneously.
The utility model discloses take following technical means:
a disposable cell preparation bag comprises a preparation bag body 5, a connecting pipe 2 and an input pipe 7; one end of the connecting pipe 2 is communicated with the upper end of the preparation bag body 5, and the other end is provided with an input needle 1 for accessing physiological saline; one end of the input pipe 7 is communicated with the lower end of the preparation bag body 5, and the other end is provided with a lockable Ruhr joint 9; the inlet pipe 7 has two functions: when in production, the cell preparation is injected into the preparation bag body 5, and when in use, the cell preparation flows out; the connecting pipe 2 and the input pipe 7 are respectively provided with a pipe clamp for controlling the flow rate.
Preferably, the preparation bag body 5 is provided with a standby valve port 6 at the bottom for extracting the cell preparation in the disposable cell preparation bag.
Preferably, a bag hanging hole 4 is formed in the upper part of the preparation bag body 5.
Further, the standby valve port 6 is provided with a butterfly head valve.
Preferably, the connecting pipe 2 and the input pipe 7 are both made of plastic materials.
Preferably, a protective cap is arranged on the luer 9.
The beneficial effects of the utility model reside in that:
1) The physiological saline can be directly supplemented inwards through the connecting pipe and the input needle head in the use process of the cell preparation bag, so that cell waste is avoided;
2) The patient can use uninterruptedly in the use process, and the operation difficulty and the operation risk caused by additionally and independently flushing the cell preparation bag are avoided.
3) Facilitates cell infusion and reduces the risk of contamination of the cell preparation.
Drawings
FIG. 1 is a schematic structural diagram of the disposable cell preparation bag of the present invention.
In the figure, 1, an input needle, 2, a connecting pipe, 3, an upper pipe clamp, 4, a lacing hole, 5, a preparation bag body, 6, a spare valve port, 7, an input pipe, 8, a lower pipe clamp and 9, a luer connector.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the following detailed description.
Referring to fig. 1, a disposable cell preparation bag comprises a preparation bag body 5, a connecting pipe 2 and an input pipe 7; one end of the connecting pipe 2 is communicated with the upper end of the preparation bag body 5, and the other end is provided with an input needle 1 for accessing physiological saline; one end of the input pipe 7 is communicated with the lower end of the preparation bag body 5, and the other end is provided with a lockable luer connector 9; the inlet pipe 7 has two functions: when in production, the cell preparation is injected into the preparation bag body 5, and when in use, the cell preparation flows out; the connecting pipe 2 and the input pipe 7 are respectively provided with a pipe clamp for controlling the flow rate.
