The invention will be described in detail hereinafter with reference to exemplary embodiments in the drawings. It should be understood, however, that the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the invention to those skilled in the art.

In the description of the present invention, it is to be understood that the terms "center", "lateral", "longitudinal", "front", "rear", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are used only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the scope of the invention.

The defect that operating tables are easily polluted because polyps are contained by gauze in the prior art is overcome. The inventors have conducted careful analysis and found that the above-mentioned technical problems are mainly caused by: since the polyp is taken from the rectum into the gall bladder, the bile of the patient can be drawn out together during the drawing process, and the operating table is easy to be polluted. Based on the analysis, the inventor designs a sample collection device, collects polyp sample through the collecting flask of sample collection device, is difficult to pollute the operating table.

As shown in fig. 1-2, in one embodiment of the present invention, the specimen collection device includes a catheter 1, a suction pump 2 and a collection bottle 3, one end of the catheter 1 is communicated with the endoscope, the other end is communicated with the collection bottle 3 through a joint 4, and the suction pump 2 is installed on the catheter 1; the connector 4 comprises a male connector 41 and a female connector 42, the male connector 41 is inserted into the female connector 42 and is in threaded connection with the female connector, the male connector 41 is connected with the catheter 1, and the female connector 42 is connected with the collecting bottle 3. The male connector 41 is provided with a mounting hole, the catheter 1 is inserted into the mounting hole and fixedly connected with the mounting hole, and after the male connector 41 is connected with the female connector 42, the catheter 1 is inserted into the collecting bottle 3. The catheter 1 is provided with a switch valve 6, the switch valve 6 being located between the aspiration pump 2 and the collection bottle 3. When the collecting bottle 3 is required to be detached and polyp is taken out, the switch valve 6 is closed, and residual liquid in the catheter 1 is not easy to flow onto an operating table and pollute the operating table.

Optionally, a filtering membrane 5 is arranged in the collecting bottle 3, and the filtering membrane 5 divides the interior of the collecting bottle 3 into an upper part and a lower part; the filter membrane 5 is provided with equidistant filter holes 51. Bile, flushing fluid and polyp are separated through the filtering membrane 5, so that the polyp is placed on the filtering membrane 5, and the polyp can be conveniently taken by the specimen forceps.

Alternatively, the collection bottle 3 comprises a body 31 and a cap 32, the cap 32 being inserted into the body 31 and screwed thereto; the filter membrane 5 is disposed in the flask 31, and the female connector 42 is connected to the flask cover 32. A limiting ring 33 protrudes from the inner wall of the bottle body 31, the limiting ring 33 is positioned above the filter membrane 5, and after the bottle cover 32 rotates, the bottom of the bottle cover 32 is propped against the limiting ring 33. The surface of the limiting ring 33 is covered with a layer of elastic pad. The thickness of the limiting ring 33 is consistent with that of the bottle cover 32. The collecting bottle 3 is made of transparent material. The bottle cover 32 is opened, the opening of the collecting bottle 3 can be enlarged, and the specimen forceps can clamp the polyp conveniently. The bottle cover 32 bottom pushes up in the spacing ring 33, prevents that the bottle cover 32 bottom touching filtration membrane 5 from protecting filtration membrane 5. Meanwhile, the sealing performance of the joint of the bottle cap 32 and the bottle body 31 is improved. The bottle cover 32 bottom is pressed on the cushion, and under the pressure effect, the bottle cover 32 bottom forms the recess on the cushion easily, improves the leakproofness of bottle cover 32 and bottle 31 junction, and simultaneously, the bounce-back force of cushion acts on the bottle cover 32 bottom, and the bottle cover 32 is difficult to rotate, improves the stability that bottle cover 32 and bottle 31 are connected. The thickness of the limiting ring 33 is consistent with that of the bottle cover 32, so that no step exists at the joint of the bottle cover 32 and the bottle body 31, and bile, flushing fluid and polyp in the collecting bottle 3 are not easy to remain at the joint of the bottle cover 32 and the bottle body 31. The collection bottle 3 is made of transparent materials, so that polyps in the collection bottle 3 can be observed conveniently, and the polyps can be taken by the specimen tweezers conveniently.

The application method of the infusion patch comprises the following steps:

in use, the catheter 1 is first connected to an endoscope, and the on-off valve 6 is opened. Next, the suction pump 2 is activated to suck bile, washing fluid and polyps into the collection bottle 3. The bile, the flushing fluid and the polyp are separated by the filtering membrane 5, and the polyp is placed on the filtering membrane 5. Again, the on-off valve 6 is closed, and the male connector 41 is separated from the female connector 42. Finally, the jar cover 32 is opened and the polyp is removed.

It should be understood that all the above embodiments are illustrative and not restrictive, and that various modifications and changes may be made in the specific embodiments described above by those skilled in the art without departing from the spirit of the present invention.
