Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

As shown in fig. 1-3, a drainage bag comprises a liquid inlet pipe 6 above a drainage bag 1 and a liquid outlet pipe 8 below the drainage bag, wherein a liquid outlet valve 9 is arranged on the liquid outlet pipe 8, a diaphragm 2, a control valve 4 and a liquid taking pipe 3 are sequentially arranged on one corner below the drainage bag 1, one end of the liquid taking pipe 3 is connected with the control valve 4, the other end of the liquid taking pipe is provided with a sealing cover 12 which can be detachably connected, and the diaphragm 2 can be pierced by the control valve 4. The control valve 4 comprises a fixed body 41 which is integrally formed with the drainage bag 1, a hollow sharp puncture tube 43 which is detachably connected is arranged at the center of the fixed body 41, a rotating body 42 is arranged between one end of the hollow sharp puncture tube 43 and the liquid taking tube 3, and a sharp puncture part 44 is arranged at the other end of the hollow sharp puncture tube. The middle end of the hollow prick tube 43 is provided with a detachable connected snap ring 5, and the snap ring 5 is positioned between the rotating body 42 and the fixed body 41. The hollow prick tube 43, the rotary body 42 and the liquid taking tube 3 are integrally formed. The hollow prick tube 43 is provided with a sealing ring 11, and the sealing ring 11 is positioned between the rotating body 42 and the fixed body 41. The hollow spike tube 43 is threadedly coupled to the fixing body 41. The liquid outlet regulator 10 is arranged on the liquid taking pipe 3. A hanging ring 7 is arranged above the drainage bag 1.

When the drainage device is used, a specimen liquid enters the drainage bag 1 through the liquid inlet pipe 6, a doctor can take the liquid according to the condition of a patient, the sealing cover 12 and the liquid taking pipe 3 are detached and separated during liquid taking and then are inserted into an experimental vessel, then the hollow sharp puncture pipe 43 on the control valve 4 moves towards the diaphragm 2 along the fixed body 41, the sharp puncture part 44 punctures the diaphragm 2, so that the specimen liquid flows into the liquid taking pipe 3 through the control valve 4 to sample the specimen, the liquid taking pipe 3 can be lifted up after sampling to prevent the specimen liquid from flowing out, then the sealing cover 12 is hermetically connected with the liquid taking pipe 3, and the liquid outlet regulator 10 can be additionally arranged on the liquid taking pipe 3 to control the flow speed and the flow of the specimen liquid; the control valve 4 and the liquid taking pipe 3 can also replace a liquid outlet pipe 8 and a liquid outlet valve 9, but considering that the liquid outlet pipe 8 needs to discharge liquid outwards frequently, the liquid outlet is exposed for multiple times, in order to avoid the influence of multiple use on the detection result, the original liquid outlet pipe 8 and the original liquid outlet valve 9 are recommended to be reserved, and the drainage bag 1 needs to be replaced once in two days under the general condition; this drainage bag simple structure, low in manufacturing cost punctures diaphragm 2 through control valve 4 and combines sealed lid 12 and liquid taking pipe 3, effectively solves the problem of getting aseptic sample, and the true result of drainage liquid microorganism culture of accurate reaction is prevented through snap ring 5 that drainage bag 1 from not being punctured in the use, avoids the problem of control valve 4 weeping through sealing ring 11.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
