[0022] The technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-5 As shown, a lung lavage fluid collection device includes an outer tank body 1, an upper cover 2 and a connecting hose 3. The connecting hose 3 penetrates through the inside of the upper cover 2, and the end of the connecting hose 3 is located inside the outer tank body 1. The lung lavage fluid flows into the inside of the outer tank body 1 from the connecting hose 3. A negative pressure bag 4 is arranged inside the outer tank body 1, and the lung lavage fluid flowing into the outer tank body 1 is collected through the negative pressure bag 4. A connecting structure 5 is connected between the top end of the negative pressure bag 4 and the connecting hose 3, and the connecting hose 3 is connected to the negative pressure bag 4 through the connecting structure 5. The connecting structure 5 includes a first joint 51 and a second joint 52. The first joint 51 is arranged at the end of the connecting hose 3, the second joint 52 is arranged at the top end of the negative pressure bag 4, and a mutually matching first connection port 53 and a second connection port 54 are respectively opened inside the first joint 51 and the second joint 52. The connecting hose 3 and the negative pressure bag 4 can be connected or separated from each other through the detachable connecting structure 5.

[0024] In this embodiment, the shapes of the first connection port 53 and the second connection port 54 match each other. The first connection port 53 of the first joint 51 is engaged with the second connection port 54 of the second joint 52. After aligning and pressing the first joint 51 and the second joint 52, the first connection port 53 and the second connection port 54 are engaged with each other at this time.

[0025] In this embodiment, an anti-overflow structure 6 is provided on the bottom surface of the upper cover 2 and located outside the connecting hose 3. The anti-overflow structure 6 includes a reserved groove 65 which is opened on the bottom surface of the upper cover 2. A fixing sleeve 61 is arranged inside the reserved groove 65. The fixing sleeve 61 is located at the bottom end of the upper cover 2, and the position of the mating groove 62 is aligned with the position of the reserved groove 65. The fixing sleeve 61 is engaged with the inside of the reserved groove 65, and the fixing sleeve 61 is sleeved outside the connecting hose 3. A mating groove 62 is formed on the side wall of the fixing sleeve 61. A mating block 63 is slidably connected inside the mating groove 62. The cross-section of the mating groove 62 is adapted to the cross-section of the mating block 63. The mating block 63 slides along the inside of the mating groove 62. An airbag 64 is placed inside the reserved groove 65 and on one side of the mating block 63. A part of air is filled inside the airbag 64, and when the bottom of the airbag 64 is squeezed, the air can fill the upper part of the airbag 64.

[0026] In this embodiment, one end of the airbag 64 is in contact with the mating block 63, and the bottom end of the airbag 64 is in contact with the top end of the negative pressure bag 4. When the liquid in the negative pressure bag 4 increases, it will be in contact with the airbag 64. After the negative pressure bag 4 is filled, the airbag 64 is squeezed by the negative pressure bag 4. At this time, the gas in the airbag 64 is squeezed to the upper part of the airbag 64.

[0027] In this embodiment, the end of the mating block 63 is provided with a rounded corner, and the end of the mating block 63 is in contact with the connecting hose 3. The squeezed airbag 64 pushes the mating block 63 to move along the inside of the mating groove 62. When the mating block 63 is in contact with the connecting hose 3, the liquid inside the connecting hose 3 can be blocked.

[0028] It should be noted that when the present utility model is in use, after the lung lavage fluid is extracted by a medical instrument, it will flow into the interior of the outer tank body 1 along the connecting hose 3. In order to reduce the pollution of the interior of the outer tank body 1 by the lung lavage fluid and quickly take out the lung lavage fluid, at this time, the negative pressure bag 4 can be placed inside the outer tank body 1, and the negative pressure bag 4 and the connecting hose 3 are connected through the connecting structure 5. Specifically, the first joint 51 at the end of the connecting hose 3 is aligned with the second joint 52 at the top of the negative pressure bag 4, and the first connection port 53 of the first joint 51 and the second connection port 54 of the second joint 52 are engaged with each other to prevent the connecting hose 3 from falling off the outer tank body 1, so that the connecting hose 3 and the negative pressure bag 4 can be connected together. Then, the lung medical instrument extracts the lung lavage fluid and flows it into the interior of the negative pressure bag 4, and the negative pressure bag 4 is used for collection and storage. After the negative pressure bag 4 is filled with the lung lavage fluid, the first joint 51 and the second joint 52 can be separated, which is convenient for replacing the filled negative pressure bag 4 and can also reduce the pollution of the interior of the outer tank body 1 by the lung lavage fluid. When the interior of the negative pressure bag 4 is filled with liquid, the liquid in the negative pressure bag 4 will squeeze the airbag 64, and all the gas inside the airbag 64 is squeezed to the upper part of the airbag 64. The airbag 64 abuts against the fitting block 63 and moves along the inside of the fitting groove 62. Thus, the end of the fitting block 63 can block the liquid inside the connecting hose 3 to prevent the liquid in the connecting hose 3 from continuing to flow into the interior of the negative pressure bag 4. When the upper cover 2 is pulled out of the outer tank body 1, the liquid inside the connecting hose 3 will not flow when the upper cover 2 moves along the connecting hose 3. Pinch the connecting hose 3 with your finger, and then separate the first joint 51 and the second joint 52, which can avoid the situation of overflow or explosion caused by too much liquid in the negative pressure bag 4. After replacing the new negative pressure bag 4, the negative pressure bag 4 will not squeeze the airbag 64. At this time, when the liquid flows into the interior of the new negative pressure bag 4 from the connecting hose 3, it can flow into the interior of the negative pressure bag 4. At this time, the un-squeezed airbag 64 will not block the flow of the connecting hose 3.
