[0015] In order to more clearly illustrate the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0016] In the following description, the example details are given to provide a deeper understanding of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. It should be understood that the specific embodiments are only used to explain the utility model, and are not used to limit the utility model.

[0017] It should be understood that when the terms "include" and / or "comprises" are used in this specification, they indicate the existence of the stated features, integers, steps, operations, elements or components, but do not exclude the existence or addition of one or more other features, integers, steps, operations, elements, components or combinations thereof.

[0018] At present, when performing colonoscopy or gastroscopy, it is necessary to remove the polyps or diseased tissues found in the body and preserve them as specimens, and then perform pathological analysis on the specimens. The method for removing the specimens is to directly suck out the removed specimens through a negative pressure tube. Generally, the method for intercepting the specimens is to wrap and fix a layer of gauze on one end of the negative pressure tube mouth, and intercept the specimen through the gauze. However, sometimes the gauze will be sucked into the negative pressure tube together with the specimen due to the excessive suction force of the negative pressure tube, causing certain troubles. Therefore, there is an urgent need for a negative pressure connecting tube that can collect specimens.

[0019] In order to solve the above technical problems, the present application provides a negative pressure connecting tube for collecting specimens, see Figures 1-3 The utility model discloses a negative pressure connecting tube for collecting specimens, comprising a collecting bottle 1 and an end cap 2, one end of the collecting bottle 1 is detachably connected to one end of the end cap 2, the other end of the end cap 2 is provided with a first pipe 3, a suction pipe is sleeved on the first pipe 3, the other end of the collecting bottle 1 is provided with a second pipe 4, a negative pressure pipe is sleeved on the second pipe 4, the negative pressure pipe is connected to the negative pressure device, and the negative pressure pipe is connected to the negative pressure device. By setting the collecting bottle 1 and the end cap 2, on the one hand, the specimen can be sucked into the collecting tube through the suction pipe, and on the other hand, the liquid can be discharged through the negative pressure pipe. Since the collecting bottle 1 and the end cap 2 are detachably connected, the connection method between the two can be and is not limited to detachable connection methods such as threaded connection, buckle connection or magnetic connection. After the specimen is sucked out, the collecting bottle 1 can be separated from the end cap 2 to take out the specimen. Compared with setting gauze in the pipeline to intercept the specimen, the collecting bottle 1 of the utility model can intercept the specimen in the bottle to prevent the specimen from being sucked into the negative pressure pipeline, thereby improving the working efficiency of medical staff.

[0020] The working principle of the utility model is:

[0021] First, the specimen is sucked from the first pipe 3 into the collecting bottle 1 through the suction tube. Since the collecting bottle 1 is provided with a filter pocket 5, the filter pocket 5 filters the outflowing liquid through the gauze and flows out from the second pipe 4 through the negative pressure tube. The specimen is retained in the filter pocket 5. The waterproof gasket 7 provided on the inner wall surface of the end cover 2 can prevent the liquid from flowing out from the matching gap between the end cover 2 and the collecting bottle 1. After the specimen is sucked, the collecting bottle 1 and the end cover 2 are separated, and then the specimen can be taken out.

[0022] The filter bag 5 also includes a cylindrical filter bag 5 with an opening at one end. The wall of the filter bag 5 is a hollow structure. The inner wall of the collection bottle 1 is provided with a raised clamping strip 6. The edge of the open end of the filter bag 5 extends to fit the inner wall of the collection bottle 1. The filter bag 5 is embedded in the collection bottle 1 through the clamping strip 6.

[0023] In another embodiment, all the technical features of the above embodiment are included. A filtering pocket 5 with an opening at one end is further provided in the collection bottle 1. The filtering pocket 5 is columnar and has a hollowed-out wall surface. A raised clamping strip 6 is provided on the inner wall surface of the collection bottle 1. The edge of the filtering pocket 5 with the opening extends to fit the inner wall surface of the collection bottle 1. The filtering pocket 5 is embedded into the interior of the collection bottle 1 through the clamping strip 6. The filtering pocket 5 can collect the specimen, and the bottom of the filtering pocket 5 can block the suction of the negative pressure tube to prevent the specimen from being sucked into the negative pressure tube.

[0024] In another embodiment, all the technical features of the above embodiment are included. An external thread is provided on the outer wall surface of the collection bottle 1, and an internal thread is provided on the inner wall surface of the end cap 2. The collection bottle 1 is threadedly connected to the end cap 2. Or conversely, an internal thread is provided on the inner wall surface of the collection bottle 1, and an external thread is provided on the outer wall surface of the end cap 2. Since the thread technical feature is already very mature, it is not shown in the drawings. It can be understood that the connection manner between the collection bottle 1 and the end cap 2 can also be combined by other detachable manners such as snap connection.

[0025] In another embodiment, all the technical features of the above embodiment are included. In order to ensure that there is no water leakage problem during the working process, a waterproof gasket 7 is provided at one end of the end cap 2 close to the collection bottle 1. The waterproof gasket 7 is adhered to the inner end surface of the end cap 2. When the end cap 2 is connected and matched with the collection bottle 1, the waterproof gasket 7 increases the sealing performance and can also make the connection and matching between the end cap 2 and the collection bottle 1 tighter, preventing the liquid from flowing out through the gap.

[0026] In another embodiment, all the technical features of the above embodiment are included. One end of the collection bottle communicating with the second pipe is frustum-shaped. The frustum-shaped structure can increase the negative pressure suction and make the liquid suction smoother.

[0027] The advantages of the present utility model are as follows:

[0028] 1) The liquid is discharged through the filtering pocket, and at the same time, the specimen is collected in the collection bottle, avoiding the situation that the specimen is sucked into the negative pressure tube, and improving the work efficiency of medical staff.

[0029] The above discloses only several specific embodiments of the present utility model, but the present utility model is not limited thereto. Any change that can be thought of by those skilled in the art should fall within the protection scope of the present utility model.
