Referring to fig. 1 to 13, as an embodiment of the present invention, the thoracic surgery waste liquid treatment device includes a treatment tank 1 having an opening at a top thereof, wherein a bottom of the treatment tank 1 is open and sealed by a bottom cover 21 in threaded engagement; the bottom of the treatment tank 1 can be sealed by the bottom cover 21, and when cleaning or maintenance is required, the parts inside the treatment tank 1 can be repaired or replaced by removing the bottom cover 21.
Specifically, the outer wall of the bottom lid 21 has an external thread at its upper portion, and the inner wall of the treatment tank 1 has an internal thread at its lower portion to be engaged with the external thread at the upper portion of the outer wall of the bottom lid 21.
An elastic sealing component matched with the opening is arranged above the inside of the treatment tank 1, a disinfection barrel 13 used for containing disinfectant is arranged outside the treatment tank 1, the bottom of the disinfection barrel 13 is communicated with a valve 11 penetrating through the side wall of the treatment tank 1 through a conduit 12, a blocking structure matched with the valve 11 is arranged inside the treatment tank 1, and the blocking structure is connected with the elastic sealing component; after the plugging structure and the elastic sealing assembly are connected, synchronous opening and closing of the plugging structure and the elastic sealing assembly are realized, the ratio of the discharge amount of waste liquid to the discharge amount of disinfectant is kept constant, and the automatic proportioning function is realized.
Specifically, when the interior of the treatment tank 1 is communicated with the outside through the opening, the elastic sealing assembly drives the plugging structure to open the valve 11, so that when the elastic sealing assembly is opened, pleural effusion to be treated can be discharged into the treatment tank 1 through the opening, and meanwhile, the elastic sealing assembly opens the valve 11 through the plugging structure, so that disinfectant in the disinfection barrel 13 flows into the treatment tank 1 through the conduit 12 and the valve 11, and the pleural effusion discharged into the treatment tank 1 from the opening is disinfected.
The longer the opening is communicated with the outside, the more waste liquid is discharged into the treatment tank 1, the longer the valve 11 is opened, and the more disinfectant is discharged into the treatment tank 1, so that the waste liquid and the disinfectant discharged into the treatment tank 1 are in positive correlation.
The inside below of treatment tank 1 is provided with detachable fixed bucket 20 internal rotation is provided with blending tank 19, be provided with the mixing mechanism in the blending tank 19, the mixing mechanism is used for will discharging through the opening waste liquid in the blending tank 19 and discharging through valve 11 and go into the antiseptic solution in the blending tank 19 fully fuses to with the help of the germ inactivation of antiseptic solution in with the waste liquid.
In this embodiment, can be with the opening shutoff of treatment tank 1 through the elasticity sealing component who sets up, make it only can open under having exogenic action, will handle 1 inside through opening and external intercommunication of tank, and when elasticity sealing component opened, open valve 11 with the help of block structure, realize pouring into the waste liquid in to treatment tank 1, automatic to the internal antiseptic solution that injects of jar, and the discharge of antiseptic solution and the discharge of waste liquid become fixed proportion, reach the function of automatic ratio.
After the disinfectant and the waste liquid are discharged into the mixing barrel 19 in the treatment tank 1, the disinfectant and the waste liquid are fully contacted and uniformly mixed by the mixing mechanism, and germs in the waste liquid are killed.
Referring to fig. 6 to 11, as another embodiment of the present invention, a fillet 36 is fixed on an outer wall of the fixing barrel 20 and is parallel to an axis thereof, and a caulking groove 37 adapted to the fillet 36 is provided on an inner wall of the processing tank 1. The fitting of the fillet 36 and the caulking groove 37 prevents the fixing barrel 20 from rotating relatively to each other after the fixing barrel is loaded into the treatment tank 1.
After the stationary tub 20 is loaded into the treatment tank 1, the bottom cover 21 is screwed into the bottom of the treatment tank 1, and the stationary tub 20 is supported on the bottom cover 21 by gravity.
A first clamping ring 24 is fixedly arranged on the inner wall of the treatment tank 1, and a circle of first adhesive tape 25 which is in sealing fit with the outer wall of the top of the fixed barrel 20 is clamped in the first clamping ring 24. When the fixed tank 20 is loaded into the treatment tank 1 and pulled by the bottom cover 21, the outer wall of the top of the fixed tank 20 is tightly adhered to the first adhesive tape 25, and the waste liquid and the disinfectant are prevented from flowing onto the bottom cover 21 along the inner wall of the treatment tank 1 from the gap between the fixed tank 20 and the inner wall of the treatment tank 1.
A second clamping ring 26 is fixedly arranged on the inner wall of the fixed barrel 20, and a circle of second adhesive tape 27 which is used for being matched with the outer wall of the top of the mixing barrel 19 in a sealing mode is clamped in the second clamping ring 26. When the device is used, the mixing barrel 19 is firstly arranged in the fixed barrel 20, a gap between the mixing barrel 19 and the fixed barrel 20 is sealed by means of the second clamping ring 26 on the inner wall of the fixed barrel 20 and the second rubber strip 27 clamped in the second clamping ring 26, then the fixed barrel 20 with the mixing barrel 19 is arranged in the treatment tank 1, and the fixed barrel 20 with the mixing barrel 19 is screwed in from the bottom of the treatment tank 1 through the bottom cover 21 to support the fixed barrel 20.
After the mixing barrel 19 and the fixed barrel 20 are loaded into the treatment tank 1, when waste liquid or disinfectant is filled into the treatment tank 1, the waste liquid and the disinfectant can be prevented from flowing onto the bottom cover 21 along a gap between the fixed barrel 20 and the inner wall of the treatment tank 1 under the matching action of the first clamping ring 24 and the first adhesive tape 25; after the waste liquid and the disinfectant enter the fixed barrel 20, the waste liquid and the disinfectant can be prevented from flowing into the bottom of the fixed barrel 20 along the gap between the mixing barrel 19 and the inner wall of the fixed barrel 20 by the matching of the second clamping ring 26 and the second adhesive tape 27.
In conclusion, through the first clamping ring 24, the first rubber strip 25, the second clamping ring 26 and the second rubber strip 27, the waste liquid and the disinfectant are finally gathered in the mixing barrel 19.
In addition, a hemispherical dent is arranged at the center of the outer side of the bottom of the mixing barrel 19, a hemispherical dent is also arranged at the center of the inner side of the bottom of the fixed barrel 20, the diameters of the two hemispherical dents are the same, a rolling ball is arranged between the two hemispherical dents, after the mixing barrel 19 is loaded into the fixed barrel 20, the mixing barrel 19 is supported by the rolling ball, and under the action of the spherical dent and the rolling ball, the mixing barrel 19 can be prevented from shaking in the fixed barrel 20 by matching with a second rubber strip 27; in addition, when mixing barrel 19 rotated relative to fixed bucket 20, because the bearing capacity of mixing barrel 19 mainly gathers on the spin, consequently, compare with directly laminating the bottom of mixing barrel 19 in the bottom of fixed bucket 20, reduced area of contact, greatly reduced the friction when the two rotated relatively.
As another embodiment of the present invention, referring to fig. 2 to 5, the elastic sealing assembly includes a mounting ring 5 fixed in the processing tank 1, a sealing ring 2 embedded in the opening, a movable sleeve 3 having an upper outer wall hermetically and slidably attached to the sealing ring 2, a fixed sleeve 4 fixed on the mounting ring 5, and a first pressure spring 6 elastically connecting the movable sleeve 3 and the fixed sleeve 4;
