It is worth noting that the length of the upper layer of the package piece 14 used to form the inflatable cavity 11 is greater than the size of the adhesive film 12, which makes the inflatable and expanded upper layer of the package piece 14 relative to the adhesive film 12 based on the limitation of the adhesive film 12, and the adhesive film 12 is arched and expanded;
[0018] Further, the arc-shaped collection bag 1 is provided with a clamping mutual adhesive port 13 at both ends, which is made of a piece of material extended by the inflatable cavity 11, and the clamping mutual adhesive port 13 includes an outer flap 131 and an inner flap 132, and a glue layer 133 is arranged between the outer flap 131 and the inner flap 132;
[0019] As described above, when two or more arc-shaped collection bags 1 are used at the same time, the release paper on the glue layer 133 is peeled off first, and then the edges of the two arc-shaped collection bags 1 are bonded by alternately pasting the outer flap 131 and the inner flap 132 of the first arc-shaped collection bag 1 with the outer flap 131 and the inner flap 132 of the second arc-shaped collection bag 1, as shown in Figure 2 The edge is sealed and connected, and multiple combinations can be set according to the needs of the surgical field, which is set below the surgical opening when lying on the side, and is set to enclose the surgical opening when lying on the back, and it is worth noting that the multiple connected arc-shaped collection bags 1 have their edges abutting the adhesive film 12, so that the liquid drainage flows into the arc-shaped collection bag 1, and the adhesive film 12 and the glue layer 133 are made of waterproof adhesive material;
[0020] The second is the liquid pipe 2, and the liquid pipe 2 is connected at both ends to the liquid inlet 35 provided on the water reservoir 31 at the end of the arc-shaped collection bag 1 and the collection part 3, for draining the liquid collected by the arc-shaped collection bag 1 into the collection part 3;
[0021] The third is the collection part 3, and the collection part 3 of the embodiment includes a water reservoir 31 and an air extraction unit 34, which is used to assist the water reservoir 31 to actively extract the water in the arc-shaped collection bag 1, so as to avoid the accumulation of the arc-shaped collection bag 1 due to poor flow of the liquid pipe 2;
[0022] The water accumulator 31 is provided with a liquid inlet 35 and an exhaust port 36, the liquid inlet 35 and the exhaust port 36 are provided with a one-way structure 32, the one-way structure 32 is used for cooperating with the air extraction unit 34 to make the liquid and gas flow in one direction in the device, the air extraction unit 34 of the embodiment is used for cooperating with the one-way structure 32 to one-way suck the water liquid accumulated in the arc-shaped collecting bag 1, the water accumulator 31 further comprises a connecting port 38 for the air extraction unit 34, the air extraction unit 34 comprises an electric uniform speed air pump 341 and a manual presser 342, and the water accumulator 31 is a barrel-shaped hard container made of plastic;
[0023] The water accumulator 31 is provided with at least one liquid inlet 35, the liquid inlet 35 comprises a column port 352 and a cap 351, the liquid pipe 2 is connected to the column port 352 in use, a plurality of annular anti-slip rings are further arranged on the column port 352, the column port 352 needs to be closed by the cap 351 when the liquid pipe 2 is not connected, the one-way structure 32 comprises a reset spring 321, a plug column 322 and a threaded seat 323, the column port 352 is provided with an internal screw hole 324 matched with the threaded seat 323, in installation, the plug column 322 and the reset spring 321 are placed in the groove of the threaded seat 323, the threaded seat 323 is screwed and locked into the internal screw hole 324 of the column port 352 to complete fixation, when a plurality of column ports 352 are used, the water liquid in the arc-shaped collecting bag 1 flows from the liquid pipe 2 to the water accumulator 31, the arrangement of the exhaust port 36 destroys the sealing internal pressure of the cavity of the water accumulator 31, so that the water liquid can push open the plug column 322, but the water liquid may also exist the problem of being unable to push open, therefore, it is necessary to arrange the air extraction unit 34 of the embodiment, in use, the exhaust port 36 is closed first, then the electric uniform speed air pump 341 continuously extracts the gas in the water accumulator 31 to form suction force to suck the liquid at the liquid pipe 2 and the arc-shaped collecting bag 1, it is worth noting that, when the air extraction unit 34 of the embodiment is used, the water liquid of the plug column gives a pressure to the plug column 322, when the liquid flow is not smooth, the column port 352 with the water liquid of the plug column is more easily conducted under the action of the air extraction unit 34, the column port 352 with the plug column is preferentially conducted, the manual presser 342 is arranged in the same way, and the same effect as the electric uniform speed air pump 341 is formed by continuously stepping and pressing.
