The recovery container is also connected with an optical analysis device, the optical analysis device analyzes the properties of drainage fluid in the recovery container through an optical method (the wound oozes much blood in the first day after operation and then gradually reduces), and when the bleeding is judged to be lower than a preset value, the optical analysis device automatically stops flushing and gives a prompt.
The water supply container 3 is further provided with a water filling port 7, and physiological saline is added into the water supply container 3 through the water filling port 7.
The color of the flushing pipe 1 is different from that of the guide pipe 2.

In order to facilitate transportation and reduce the occupied volume in the prior art, the recovery container 4 is usually made of soft plastic or rubber, and when the interior of the recovery container is kept in a vacuum environment, the inner wall surface of the recovery container 4 is attached together, so that the liquid for washing the wound cannot smoothly enter the recovery container 4. And because the vacuum pump or the hospital vacuum system is communicated with the recovery container 4, when the recovery container 4 is filled with the liquid after the wound is washed, part of the liquid overflows and enters the vacuum pump or the hospital vacuum system, so that the vacuum pump is damaged or the hospital vacuum system is polluted, and serious medical accidents are caused.
In order to solve the above problems, the present invention is also improved on the recovery tank 4.
As shown in fig. 1, the recovery container 4 of the present invention comprises a flexible inner cylinder 40 and an outer cylinder 41, wherein the top of the flexible inner cylinder 40 is hermetically connected with a circular cover 44; the top of the circular cover 44 is provided with a first joint 42 and a second joint 43, and the bottoms of the first joint 42 and the second joint 43 are both communicated with the inner space of the flexible inner cylinder 40; the top of the first joint 42 is communicated with the negative pressure device 6; the top of the second joint 43 is communicated with the outlet end of the guide tube 2; the flexible inner cylinder 40 is inserted into the outer cylinder 41, and an annular gap is defined between the flexible inner cylinder 40 and the outer cylinder 41; the first joint 42 is communicated with the annular gap through an L-shaped communicating pipe 54; a pressure reducing valve is arranged in the first joint 42 and is arranged below the connection part of the L-shaped communication pipe 54 and the first joint 42; the bottom of the first joint 42 is provided with a ball float valve; the outer surface of the outer cylinder 41 is provided with volume scales 45.
The circular cover 44 is further provided with a reinforcing rib 46 and a circular opening 58, and the circular opening 58 is sealed by a sealing cover 60.
Because the pressure reducing valve is arranged below the connection part of the L-shaped communicating pipe 54 and the first joint 42, when the negative pressure device 6 vacuumizes the flexible inner cylinder 40, the pressure inside the flexible inner cylinder 40 is slightly larger than the pressure of the annular gap between the flexible inner cylinder 40 and the outer cylinder 41 through the pressure reducing valve, so that the inner wall surfaces of the flexible inner cylinder 40 are not attached together, and the liquid for washing the wound cannot smoothly enter the recovery container 4. When the recovery container 4 is filled with the liquid after the wound is irrigated, the liquid drives the ball float valve to automatically seal the bottom of the first connector 42, so that the liquid cannot enter the vacuum pump or the vacuum system of the hospital, and the vacuum pump cannot be damaged or the vacuum system of the hospital cannot be polluted.
