Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 to 3, the negative pressure drainage collection container 2 includes a container body 21, and the container body 21 is divided into a left container body 211 and a right cover body 212, which are detachably connected. A collecting interface 22 is arranged on the top of the left container body 211, and the collecting interface 22 is used for connecting the drainage tube 3. The right cover body 212 is provided with a drainage port 23 and an auxiliary port 24. In order to filter bacteria, a filter 5 is respectively arranged on the drainage port 23 and the auxiliary port 24; this filter 5 not only can filter the bacterium but also meets water and seals, plays the effect of shutoff.

The container body 21 has a collection chamber 25 therein. A collection hole 251 and a vent hole 252 are provided in the collection chamber 25, and the vent hole 252 is located above the collection hole 251. The collection interface 22 is respectively communicated with the collection hole 251 and the vent hole 252; a stopper 253 is also provided in the collection port 22 for closing the chamber at the upper end inside the drain tube 3. The chamber is used for ventilation, so that the chamber is provided with a through hole 433 which is communicated with the ventilation hole 252. In order to filter bacteria during ventilation, a filter 5 is provided in the ventilation hole 252. The drainage lumen 31 communicates with the collection aperture 251 and the vent lumen 32 communicates with the vent aperture 252.

The auxiliary interface 24 is communicated with the vent hole 252, the drainage interface 23 is communicated with the collection cavity 25, and a partition plate 26 which blocks liquid in the collection cavity 25 from gushing upwards from below under the influence of external force is arranged in the upper area of the collection cavity 25. The partition 26 extends downward from the connecting end thereof in a lateral direction of the vessel body 21, and the free end of the partition 26 extends vertically downward with a stopper plate 27, the stopper plate 27 being spaced apart from the inner side wall of the vessel body 21. Below the collecting hole 251, a guide plate 28 is provided to guide the liquid to flow out downward. The guide plate 28 not only functions to guide the liquid but also functions to block the backflow of the liquid. Leave the certain interval between the bottom of riser 254 and vessel 21, the riser 254 has seted up the opening along its vertical direction on the vertical extension of vessel 21 and the riser. The collection chamber 25 is divided into two chambers by the riser 254. This opening is intended to open the entire collection chamber 25; the secretion is prevented from being accumulated in a half cavity of the collecting cavity 25, and the gas is not easy to be discharged from the inside.

Reinforcing ribs 29 are respectively arranged on the inner bottom wall of the container body 21 and positioned on two sides of the vertical plate 254. The bead 29 extends upwardly beyond the spacing of the riser 254 from the interior bottom wall of the container body 21. The partition 26, the vertical plate 254 and the reinforcing ribs 29 form a labyrinth structure in the container body 21 to prevent the liquid from flowing out.

The container body 21 is provided with a relief valve 6. When the air pressure inside the container body 21 reaches a certain air pressure value, the relief valve 6 is opened to relieve the pressure. A filter 5 is arranged in the pressure relief valve 6.
