Specific embodiment
The utility model is illustrated below in conjunction with the accompanying drawings.
One kind anti-backflow block-resistant type drainage system, including drainage tube 1, connecting conduit 2, liquid storing bag 3 and flow control valve 4,
The front end of the connecting conduit 2 is fixed with drainage tube 1 and is connected, and rear end is connected with liquid storing bag 3, and the connecting conduit 2 is provided with stream
Adjustable valve 4, its feature is to be sequentially provided with flow control valve 5 by liquid drain direction in the connecting conduit 2 to be returned with anti-
Stream device, the anti-recirculation device includes check (non-return) valve 6 and closed containing cavity 7, and inlet and the check (non-return) valve 6 of the closed containing cavity 7 are consolidated
Fixed connection, the liquid outlet of the closed containing cavity 7 is connected with liquid storing bag 3 through connecting conduit 2, is beneficial to by flow control valve
The flow velocity of 5 regulation liquid；When mobile liquid storing bag 3, or liquid in liquid storing bag 3 it is full and when needing to change, led by connection
Check (non-return) valve 6 on pipe 2, it is to avoid liquid is back to closed containing cavity 7 and causes patient to infect.
