A bronchoalveolar lavage fluid collection container according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

The utility model provides a bronchoalveolar lavage liquid collecting container, as shown in the figure, it is including gathering bottle 100, its characterized in that: the collecting bottle 100 is provided with a liquid outlet 1, an inlet 2 and an air outlet 3 which are respectively communicated with the inner cavity of the collecting bottle 100, the liquid outlet 1 is positioned at the bottom of the collecting bottle 100, and the joint of the air outlet 3 and the collecting bottle 100 is higher than the position of the liquid outlet 1 along the vertical direction;

a liquid collecting pipe 200 is arranged below the collecting bottle 100, a pipe orifice 4 of the liquid collecting pipe 200 faces upwards, and the pipe orifice 4 of the liquid collecting pipe 200 is detachably connected with the liquid outlet 1;

the bottom of the liquid collecting pipe 200 is provided with a narrowing section 5, and the pipe diameter of the narrowing section 5 is smaller than that of the area of the liquid collecting pipe 200 outside the narrowing section 5;

the liquid collecting pipe 200 is provided with a sealing cover 300, and the sealing cover 300 can be detachably sleeved outside the bottom of the liquid collecting pipe 200 or covered on the nozzle 4 of the liquid collecting pipe 200, so that the nozzle 4 is sealed.

In the above embodiment, it is necessary to keep the position of the air outlet 3 higher than the liquid outlet 1, so that when the gas and liquid are mixed and enter the collection bottle 100 from the inlet 2 during the alveolar lavage of the patient, the liquid can be collected to the bottom of the collection bottle 100 under the self-gravity effect and finally enter the liquid collecting tube 200 through the liquid outlet 1, and the air can be discharged through the air outlet 3. Of course, it is necessary to keep the liquid level in the collection bottle lower than the gas outlet 3 during this process, i.e. the gas outlet 3 is located above the liquid level. In this regard, the present embodiment is preferred in that the air outlet 3 is located at the top of the collection bottle 100 and communicates with the top region of the inner cavity of the collection bottle 100. The pipe diameter refers to the inner diameter of the pipe.

Further, the inlet 2 may also be disposed at the top of the collection bottle 100, so that the inlet 2 and the outlet 3 may be used in common, i.e., one of the two ports on the top of the collection bottle 100 may be used as the inlet 2, and the other one may be used as the outlet 3.

In order to facilitate the connection of the liquid collecting tube 200 with the collection bottle 100, the present embodiment is modified based on the above embodiment in that: as shown in fig. 6, the bottom of the collection bottle 100 protrudes outward to form an extension part 6 matching with the nozzle 4 of the liquid collecting tube 200, the liquid outlet 1 is positioned on the extension part 6, and the liquid collecting tube 200 is detachably connected with the extension part 6.

As one of preferable examples of the detachable connection of the liquid collecting tube 200 to the extending part 6: as shown in FIG. 6, the inner side wall of the nozzle 4 of the header pipe 200 and the outer side wall of the extension part 6 are connected by screw threads. Furthermore, a sealing element may be added between the inner side wall of the nozzle 4 of the header 200 and the outer side wall of the extension 6 to improve the sealing of the joint between the header 200 and the extension 6.

The removability between the header 200 and the extension 6 in this example is achieved by either relying on external forces to overcome the static friction between the inside wall of the nozzle 4 of the header 200 and the outside wall of the extension 6 to disengage the header 200 from the extension 6 or allowing the header 200 and extension 6 to be plugged into each other under external forces. Of course, if this example is used as a disposable medical article, the manifold 200 and extension 6 should not be re-inserted after being disassembled, so there is no need to consider the problem of the manifold 200 and extension 6 being plugged into each other.

Preferably, the liquid collecting pipe 200 is a circular tubular structure, the nozzle 4 of the liquid collecting pipe 200 is sleeved outside the extension part 6, and the outer contour of the extension part 6 is a circular tubular structure matched with the liquid collecting pipe.

The inner side wall of the sealing cover 300 is provided with internal threads 7, and the outer side wall of the liquid collecting pipe 200 is provided with external threads 8 matched with the internal threads 7 in the sealing cover 300 at the positions close to the pipe orifice 4 and the narrowing section 5, so that the sealing cover 300 is in threaded connection with the liquid collecting pipe 200. In this embodiment, where the seal cap 300 is positioned at the bottom of the drip bottle 200 for use by a health care provider, the benefits include, but are not limited to, the following 3 points:

1) The sealing cover 300 can protect the narrowing section at the bottom of the liquid collecting pipe 200, and the narrower section is prevented from being damaged due to collision in the carrying process;

2) The sealing cover 300 is used as an independent part and is not easy to lose;

3) Can make sealed lid 300 keep the cleanness in sealed lid 300 before not using to avoid making the lavage solution in the collector tube 200 contaminated when leading to sealed lid to close on mouth of pipe 4 because the pollution of sealed lid 300, disturbed detection accuracy.

Specifically, the external threads 8 on the header 200 as shown in FIGS. 6-9 include a first external thread 8.1 adjacent the nozzle 4 and a second external thread 8.2 adjacent the narrowing 5. In order to enable the same sealing cap 300 to be screwed alternatively with the first external thread 8.1 or the second external thread 8.2, the first external thread 8.1 and the second external thread 8.2 should be configured to be able to simultaneously mate with the internal thread on the sealing cap 300.

Preferably, the part of the liquid collecting pipe 200 outside the narrowing section 5 is a straight pipe, the pipe diameters of the straight pipe at any position along the axial direction are the same, and the first external thread 8.1 and the second external thread 8.2 outside the straight pipe are the same external threads.

As shown in FIGS. 7/9/12, the sealing cap 300 has an end packing 9 therein, and the diameter of the end packing 9 is larger than the outer diameter of the pipe where the spout 4 of the drip pipe 200 is located.
