Detailed Description

In order to better understand the present invention, the following embodiments are further described.

As shown in figure 1, the telescopic drainage device comprises a drainage bag 1 and a drainage extension tube 2.

One end of the drainage bag 1 is provided with an inlet pipe 5, and the other end is provided with a cross-shaped liquid discharge valve 3; drainage bag 1 is for having the drainage bag of measurement scale, and accessible 5 have the scale can measure the accurate record drainage volume of drainage bag, and accessible 6 cross flowing back valves of accessible carry out drainage liquid and discharge when needing to discharge drainage liquid. The maximum volume of the drainage bag is 1500ml, and when the drainage bag reaches the volume, drainage liquid can be discharged through the cross liquid discharge valve. The drainage bag 1 is also provided with a hook 9.

One end of the drainage extension pipe 2 is communicated with the inlet pipe 5 through a three-way valve 4, and the other end is provided with a pagoda-shaped interface or a threaded interface 6 (used for being connected with a drainage pipe). The three-way valve 4 is apart from the setting of drainage bag 15cm department, can rotate 4 directions of three-way valve as required and select to continue drainage, clamp drainage extension pipe or extract the drainage liquid and do the inspection, has avoided keeping the infection that the drainage liquid caused because of directly separating drainage extension pipe and drainage bag, has maintained the seal of drainage.

The middle section of the drainage extension tube 2 is an elastic hose 8, and the interior of the elastic hose 8 is a smooth circular inner cavity; the outside of the elastic hose 8 is provided with a telescopic corrugated pipe 7, the elastic hose 8 is completely covered, and the elastic hose 8 can stretch along with the telescopic corrugated pipe 7. The elastic hose 8 with the smooth inner wall (participating in drainage) is arranged inside the telescopic corrugated pipe 7, the telescopic corrugated pipe 7 is arranged on the outer side and does not participate in drainage between the two pipes, and drainage fluid retention cannot be caused to block the pipes.

The total length of the drainage extension pipe 2 is 1.2 meters in a contraction state, and the total length can reach 1.35 meters after the telescopic corrugated pipe 7 is completely stretched and extended. Wherein the length of the telescopic corrugated pipe is 15cm, the length of the telescopic corrugated pipe is 30cm after the telescopic corrugated pipe is completely stretched, and the telescopic corrugated pipe is arranged 20cm away from the joint (pagoda-shaped joint or threaded joint 6) of the drainage extension pipe 2.
