Fig. 1 to 5 show the utility model discloses a multifunctional drainage system, which comprises a drainage tube 10, a drainage bottle 20, a waste liquid collecting bag 30 and an adjusting valve 40.

The draft tube 10 is provided with a plurality of recesses 11 and a plurality of openings 12. The opening 12 is located in the recess 11. In the present embodiment, the groove 11 has a spiral shape. The opening 12 is a circular hole. The groove 11 makes the wall of the drainage tube 10 be a concave-convex structure, and the opening 12 is arranged in the middle of the concave structure. In specific operation process, bellied part contact organ inner wall, and open opening 12 in the middle of the structure of recessing can not direct contact tissue, can avoid pipe wall opening 12 and tissue laminating like this, reduces the damage to the tissue among the negative pressure drainage process, improves drainage efficiency greatly. The pipe wall adopts a spiral structure, so that body fluid in a larger range around the opening 12 can be sucked out in the negative pressure drainage process, and the drainage efficiency is improved.

The drainage bottle 20 is made of elastic material and is divided into two types, a and b. The drainage bottle 20 is b-shaped in this embodiment. The structure of the a-type drainage bottle 20 is shown in fig. 5.

Specifically, the drainage bottle 20 is made of elastic silicone.

The metering valve 40 includes a bonnet 41, a resilient member 42, a packing 43, a plug 44, and a body 45. The end of the bonnet 41 is provided with a vent 411, and the vent 411 has a filtering function. The bonnet 41 is internally provided with internal threads 410. The elastic member 42 is a spring. The plug 44 includes a connecting portion 440 and a blocking portion 441. The connection portion 440 extends from the blocking portion 441. The blocking portion 441 is provided with a sealing surface 4410, which sealing surface 4410 is conical. The main body 45 has a hollow structure penetrating therethrough. The bottom of the body 45 forms a bayonet. The outer wall of the main body 45 is provided with an external thread 450 and a mounting groove 451. The inner diameter of the main body 45 is larger than the diameter of the connection portion 440 and smaller than the outer diameter of the sealing surface 4410. Both ends of the elastic member 42 are fixed to the bonnet 41 and the coupling portion 440 of the plug 44, respectively. The external threads 450 of the body 45 mate with the internal threads 410 of the bonnet 41 to rotatably mount the bonnet 41 to the body 45. The plug 44 is pulled by the elastic member 42, and the sealing surface 4410 is engaged with the bayonet of the main body 45. The packing 43 is mounted to the mounting groove 451, and the packing 43 is located between the main body 45 and the bonnet 41.

When the multifunctional drainage system is used as a negative pressure drainage system, the regulating valve 40 can control the negative pressure in the drainage bottle 20. When the negative pressure exceeds a preset value, the negative pressure can overcome the pulling force of the elastic part 42 to draw the plug 44 downwards, the plug 44 is lowered below the bayonet of the main body 45, the outside air filtered by the vent hole 411 can enter the drainage bottle 20, the negative pressure can be immediately lowered, when the negative pressure is lowered to a certain value, the pulling force of the elastic part 42 overcomes the negative pressure to draw the plug 44 upwards, the plug 44 is lifted above the bayonet, the drainage system is closed, and the negative pressure is gradually recovered. The pulling force of the elastic element 42 is adjusted by rotating the valve cap 41 to adjust the height of the valve cap 41, so that the drainage bottle 20 is stabilized at different negative pressure values, and the negative pressure value of the drainage system is controlled within a certain range. As long as valve cap 41 reduces to a take the altitude, elastic component 42 loses the pulling force effect, and end cap 44 falls to the bayonet socket below, and the filterable outside air of through air vent 411 can freely pass in and out drainage bottle 20, and this drainage system just switches into the anti siphon drainage system of ordinary pressure, easy operation, convenient to use. By raising the height of the valve cap 41, the elastic member 42 pulls the plug 44 above the bayonet, and the negative pressure drainage system is formed after the air in the drainage bottle 20 is exhausted. When the drainage tube 10 is blocked, the drainage system does not need to be opened, the drainage bottle 20 is directly extruded to suck the drainage system for dredging again, and bacteria in the air are reduced to enter the drainage system.

In another embodiment, the bonnet 41 is provided with a protrusion, and the main body 45 is provided with a sliding slot and a plurality of positioning holes communicated with the sliding slot, wherein the sliding slot extends in a direction perpendicular to the direction in which the positioning holes extend. The protrusion is located in the sliding slot and the bonnet 41 is slidably connected to the body 45. During the use, when the height of valve cap 41 needs to be adjusted, the protrusion slides out from a positioning hole, slides to the sliding groove, and after sliding to the required height adjustment along the sliding groove, valve cap 41 rotates relative to main body 45, so that the protrusion slides to another positioning hole, and valve cap 41 is positioned relative to main body 45.

The above examples only represent some embodiments of the present invention, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the concept of the present invention, several modifications and improvements can be made, all according to the equivalent modifications and evolutions of the present invention, which are made to the above embodiments by the essential technology, and all belong to the protection scope of the present invention.
