When the spring 311(3) is in a normal state, the sealing plug 311(4) blocks the connecting end of the protection tube communicated with the first inner cavity, so that liquid cannot enter the protection tube, and when the spring 311(3) is contracted, waste liquid can enter the protection tube.

As shown in fig. 2, the protection tube includes a first end 312(1) and a second end 312(2), the first end 312(1) is connected to the fixing bracket 311(2), as shown in fig. 3, a first fixing plate 312(3) is disposed on an inner wall of the second end 312(2), the first fixing plate 312(3) is circular, the first fixing plate 312(3) is fixed to the inner wall of the protection tube 312, a circular hole is disposed in a middle portion of the first fixing plate 312(3), a first connection tube 314 is disposed in the circular hole, the connection cap 313 is sleeved outside the protection tube 312, and an anti-dropping block 312(4) is further disposed on an outer wall of the second end of the protection tube 312. The detachment prevention block 312(4) prevents the connection cap 313 from being detached from the protection tube and lost, and the connection cap 313 can be rotated on the protection tube 312.

As shown in fig. 2, the first connection pipe 314 includes a third end 314(1) and a fourth end 314(2), a through hole is provided on a sidewall of the third end 314(1), the first connection pipe 314 can be pushed upwards to abut against the sealing plug 311(4), so that the spring 311(3) contracts, thereby allowing the waste liquid to enter into the protection pipe 312, and the waste liquid in the protection pipe enters into the first connection pipe 314 from the through hole. The diameter of the fourth end 314(2) is smaller than that of the third end, the fourth end 314(2) is to be abutted against a one-way valve, the one-way valve is opened to the second connecting pipe, and waste liquid in the first connecting pipe 314 enters the second connecting pipe, so that the liquid enters the second chamber. As shown in fig. 3, the first fixture block 314(3) and the second fixture block 314(4) are disposed on an outer wall of the first connection tube 314, the first fixture block 314(3) is disposed above the first fixing plate 312(3), the first fixture block 314(3) may be made of rubber, the first fixture block 314(3) has a sealing and anti-dropping function, the protection tube 312 is sealed, so that the liquid entering the protection tube cannot flow out from the second end 312(2), and meanwhile, the first fixture block 314(3) is retained in the protection tube 312 by the first fixing plate 312(3), which effectively prevents the first connection tube 314 from dropping out. The second fixture block 314(4) is close to the fourth end 314(2), the second fixture block 314(4) is located on the outer side of the second end 312(2) of the protection tube, the second fixture block 314(4) plays a role in limiting, when the first connecting tube 314 pushes the second fixture block 314(4) inwards, the second fixture block 314(4) clamps the second end 312(2) so that the first connecting tube cannot continue inwards, at the moment, the spring 311(3) of the sealing part is in a contracted state, waste liquid enters the protection tube 312, and the second connecting tube can be in contact with the connecting cap 313.

As shown in fig. 1, an external thread 323 is disposed on the outer wall of the second connecting tube 321 near one end of the one-way valve, and as shown in fig. 3, a corresponding internal thread 313(1) is disposed on the inner wall of the connecting cap 313. The second connection pipe is fixed thereto by the connection cap 313, and the connection state of the first connection pipe and the second connection pipe is maintained, so that the waste liquid smoothly enters the second chamber.

In one embodiment, as shown in fig. 1, the volume of the second lumen 200 is 2/3 to 3/4 of the total volume of the blood purification waste bag. The second chamber 200 has a large volume, and can smoothly dump a large amount of waste liquid when in use. When dumping the waste liquid, will connect cap 313 and open, the power of maintaining the spring deformation disappears, the spring resumes original shape for the sealing plug is sealed the protection tube with the link of first cavity, thereby realizes that first cavity 100 is automatic airtight, can collect the waste liquid smoothly in the first cavity 100, need not stop the supply treatment of all medicines with the dialysis instrument, saves the time of dialysis, avoids changing the time of waste liquid bag and influences blood purification's quality. Meanwhile, the second chamber 200 can be disinfected after being poured, and cross contamination between the second chamber and the first chamber is avoided.

The use process comprises the following steps: when the waste liquid bag is used, the second chamber is firstly hung on the hanging hook 140 of the first chamber, the upper connecting part 310 and the lower connecting part 320 are communicated, and the whole waste liquid bag is hung on a blood purifying instrument for weighing. At this time, the first connecting pipe 314 is abutted against the one-way valve, the first connecting pipe 314 is pushed upwards to the second clamping block 314(4), the third end 314(1) is abutted against the sealing plug 311(4), the spring 311(3) is contracted, the second connecting pipe 321 is fixed at the position by using the connecting cap 313, so that the waste liquid enters the protecting pipe 312, and the waste liquid in the protecting pipe enters the first connecting pipe 314 from the through hole. The fourth end 314(2) is abutted against the one-way valve, the one-way valve is opened towards the second connecting pipe, and the waste liquid in the first connecting pipe 314 enters the second connecting pipe, so that the liquid enters the second chamber, and the waste liquid collection process in the second chamber is completed.

When waste liquid needs to be dumped in the second cavity, the connecting cap 313 is opened, the second connecting pipe can automatically fall off, at the moment, the force for maintaining the deformation of the spring disappears, the spring recovers to the original shape, so that the sealing plug seals the connecting end of the protective pipe and the first cavity, the first cavity 100 is automatically closed, and the waste liquid can be smoothly collected in the first cavity 100. Second cavity 200 takes off, send into the waste liquid pond, open sealing cap 231 of liquid outlet, with the drain pipe towards the waste liquid pond, open medical safety clamp 232, the waste liquid flows out from second cavity 200, because first cavity can collect the waste liquid by oneself, so the second cavity can possess sufficient time and wash the disinfection, prevent cross contamination, second cavity 200 after the disinfection uses down connecting portion 320 and last connecting portion 310 on the first cavity to put through, the waste liquid of storage in first cavity 100 flows into second cavity 200 through connecting portion this moment, the process of waste liquid is collected to repeated second cavity 200 room.

The present invention has been described in relation to the above embodiments, which are only examples for implementing the present invention.
