Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0023] Example: A disposable uterine tissue aspiration bottle, configured as follows Figures 1-7 As shown, the system includes a collection bottle 5, made of plastic, 180mm high, and with a bottom diameter of 80mm. A cap 4, also made of plastic, is detachably connected to the top of the collection bottle 5. The cap 4 has an end cap connecting sleeve 15, to which an end cap 2 is detachably connected. A filter screen 3, with a pore size of 2-3mm and a height of 80mm, is detachably connected to the lower end of the end cap 2. The end cap 2 has a suction port 13 for connecting to a universal conduit. The cap 4 has a negative pressure connection port 8 for connecting to an external negative pressure device. An overflow valve 12 passes through the cap 4 and is connected to the negative pressure connection port 8 to prevent excessive liquid from flowing into the negative pressure connection port 8. A vacuum hole 14 is located on the side of the cap 4 and communicates with the negative pressure connection port 8. An end cap seal 1 is fitted onto the suction port 13.

[0024] Preferably, such as Figure 2 and 6 As shown, the collection bottle 5 has a first protruding ring 16 at its upper end; the bottle cap 4 has a first L-shaped protruding ring 17 on its side, which surrounds the outer side of the first protruding ring 16; a first retaining ring 9 is provided on the inner side of the first L-shaped protruding ring 17, which abuts against the lower part of the first protruding ring 16. A sealing ring 7 is provided on the first protruding ring 16, and the upper end of the sealing ring 7 is in close contact with the bottle cap 4. The bottle cap 4 and the collection bottle 5 are connected by the first retaining ring 9 abutting against the lower part of the first protruding ring 16, and the sealing ring 7 improves the airtightness of the connection between the bottle cap 4 and the collection bottle 5.

[0025] Preferably, such as Figure 2 and 5As shown, the end cover 2 side is provided with a second L-shaped convex ring 18, which is around the outside of the end cover connecting cylinder 15; the end cover connecting cylinder 15 side is provided with a plurality of second snap ring 6; the second L-shaped convex ring 18 inside is provided with a plurality of ring groove 19, ring groove 19 and second snap ring 6 cooperation.

[0026] Preferably, as Figure 4 As shown, the end cover 2 inside is provided with a plurality of L-shaped clamping block 10; the filter screen 3 upper end side is provided with a plurality of convex block 11, convex block 11 and L-shaped clamping block 10 cooperation. When separating the end cover 2 and filter screen 3, only need to reverse rotation, so that the convex block 11 from L-shaped clamping block 10, after the end cover 2 can be achieved by lifting up, has the advantages of simple structure, fast operation.

[0027] Working principle:

[0028] The utility model discloses in using, need first with the end cover plugging 1 from suction port 13 take down, then connect with general catheter and suction port 13, connect again outside negative pressure equipment and negative pressure connecting port 8, after starting outside negative pressure equipment, the gas of collection bottle 5 is drawn away, the pressure of collection bottle 5 is strengthened, forms the suction of catheter part, and the liquid and tissue of patient are inhaled through catheter, because the existence of filter screen 3, tissue stays in filter screen 3, and liquid is permeated filter screen 3 and is stored in collection bottle 5. When the doctor needs to extract tissue postoperatively, only need to pull out end cover 2 upwards, make ring groove 19 and second snap ring 6 separate, then reverse rotation end cover 2 and filter screen 3, so that convex block 11 from L-shaped clamping block 10, after end cover 22 is taken up, realize filter screen 3 and end cover 2 separate, and tissue can be taken out from the opening of filter screen 3.
