Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

As shown in fig. 2, the auxiliary liquid discharging device of the negative pressure drainage device comprises a device frame 1 and a liquid discharging pipe 2; the device frame 1 comprises a base 11, an upright 12, a cross bar 13 and a pipe clamp 14, wherein the lower end of the upright 12 is connected with the base 11, the cross bar 13 is connected with the top end of the upright 12, and the pipe clamp 14 is connected with the cross bar 13 and can rotate; the liquid discharging tube 2 comprises a tube body 21 and a connector 22 which are connected, the connector 22 is matched with the discharging opening 31 of the negative pressure flow diverter 3, and the tube body 21 is clamped by the tube clamp 14.

When the liquid collected by the negative pressure drainage device needs to be poured into the measuring cup 4, as shown in fig. 5, the device frame 1 is vertically placed, the measuring cup 4 is placed close to the device frame 1, and the joint 22 is connected with the liquid discharge port 31 of the negative pressure drainage device 3; then the pipe clamp 14 is rotated to drive the pipe body 21 below the pipe clamp 14 to swing to the upper part of the side wall of the measuring cup 4; then the negative pressure drainage device 3 is taken up and inverted, and then the liquid can be discharged.

In the liquid discharging process, the liquid flows out of the pipe body 21, namely flows onto the side wall of the measuring cup 4, and then flows down along the side wall of the measuring cup 4, so that the liquid cannot be spilled or splashed. Even if the negative pressure drainage device 3 is squeezed to accelerate the liquid discharge, the liquid still can not be spilled and splashed.

After the liquid is discharged, the negative pressure drainage device 3 is horizontally placed, and the joint 22 is pulled out. The liquid discharge tube 2 can be cleaned and reused because it is not in contact with the patient when in use. The liquid discharge pipe 2 has low cost and can be used for one time. The assembly frame 1 should be stable to avoid falling over by the tapping tube 2. In order to improve the stability of the assembly frame 1, the weight of the base 11 may be large, and the base 11 may be made of steel. The pipe clamp 14 should have damping during rotation to prevent the pipe clamp 14 from freely rotating easily.

The measuring cups 4 used for metering may be of different sizes and thus different heights, e.g. measuring cups 4 of different sizes may be used for metering different amounts of liquid. In order to be able to accommodate different measuring cups 4, it is preferred that the uprights 12 are telescopic. So the tube body 21 can be ensured to be close to the upper part of the side wall of the measuring cup 4 through the telescopic upright rod 12. The telescopic pole is prior art, and the pole setting 12 can refer to the current telescopic pole design.

The specific structure of the pipe clamp 14 and the pipe body 21 is preferably as shown in fig. 3, and the pipe clamp 14 comprises a hard sleeve 141 and an elastic sleeve 142 connected in the hard sleeve 141; the tube body 21 comprises a flexible tube 211 and a hard tube 212, the flexible tube 211 is connected with the joint 22, the hard tube 212 penetrates through the pipe clamp 14, and the elastic sleeve 142 presses the hard tube 212. The hard tube 212 passes through the pipe clamp 14, and the elastic sleeve 142 presses the hard tube 212, so that the fixing of the pipe body 21 is realized. The wand 212 may be pulled off the cartridge 14 to remove the casting tube 2 for cleaning or replacement. The elastic sleeve 142 may be made of rubber.

The liquid discharge port 31 of the existing negative pressure drainage device 3 is usually a light hole. Fitting 22 mates with tap 31 so that, correspondingly, as shown in FIG. 4, the particular configuration of the fitting can be such that it includes a rigid inner liner 221 and an elastomeric outer layer 222 attached to the surface of rigid inner liner 221, and fitting 22 can be plugged into tap 31 of negative pressure flow diverter 3. The resilient outer layer 222 may compress the discharge port 31 to prevent it from falling out and to effect a seal. The resilient outer layer 222 may also be made of rubber.
