Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the protection scope of the utility model. It is understandable that the drawings are only provided for reference and illustration, and are not used to limit the utility model. The connection relationship shown in the drawings is only for the convenience of clear description and does not limit the connection method.

[0016] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to another component, or there may be an intermediate component at the same time. Unless otherwise defined, all technical and scientific terms used in this document have the same meaning as those generally understood by technicians in the technical field of the present invention. It should also be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. The terms used in this document in the specification of the present utility model are only for the purpose of describing specific embodiments, and are not intended to limit the present utility model.

[0017] Please refer to Figure 1 , Figure 2 and Figure 3 A laboratory nasal and lung lavage device comprises an lavage head 1 and a fixing clamp 8, one side of the lavage head 1 is connected with a hollow needle tube 2, one side of the hollow needle tube 2 is provided with a first connecting block 3, one side of the first connecting block 3 is provided with a second connecting block 4, one side of the second connecting block 4 is connected with a connecting hose 5, one end of the connecting hose 5 is provided with a connecting head 6, one side of the connecting head 6 is fixedly connected with a syringe connector 7.

[0018] In the specific implementation process, Figure 1-Figure 3 As shown, one side of the first connection block 3 is fixedly connected to a limiting block 9 , the number of the limiting blocks 9 is set to two, and an arc-shaped groove 10 is opened on the inner wall of the limiting block 9 .

[0019] The inner wall of the second connecting block 4 is provided with a limiting groove 11 used in conjunction with the limiting block 9, and the inner wall of the limiting groove 11 is slidably connected with an arc-shaped clamping block 12 used in conjunction with the arc-shaped clamping groove 10, and one side of the arc-shaped clamping block 12 is fixedly connected with a spring 13, and one end of the spring 13 is fixedly connected to the inner wall of the second connecting block 4.

[0020] A sealing gasket 14 is provided on one side of the second connecting block 4 .

[0021] It should be noted that the lavage head 1 is blunt-headed and expandable, which is convenient for flushing out the lavage fluid and will not damage the animal tissue. There will be resistance when the head reaches the part that needs lavage, and then the fixing clamp 8 can be used to fix the device for lavage. The connecting head 6 is used to connect the connecting hose 5 with the syringe connector 7, so as to facilitate the use of a syringe to inject the lavage fluid into the connecting hose 5. When in use, first move the first connecting block 3 so that the limit block 9 on one side is inserted into the limit groove 11 on the inner wall of the second connecting block 4. When the limit block 9 enters the limit groove 11, the limit block 9 will squeeze the arc-shaped card block 12, and the arc-shaped card block 12 will retract into the second connecting block 4 under the squeeze. At this time, the spring 13 is in a compressed state, and then continue to move the first connecting block 3. When the position of the arc-shaped card groove 10 coincides with the position of the arc-shaped card block 12, the limit block 9 no longer squeezes the arc-shaped card Block 12, at this time, the arc-shaped block 12 can be automatically reset and stuck into the arc-shaped slot 10 through the rebound force of the spring 13, so that the first connecting block 3 and the second connecting block 4 are fixed, so that the connecting hose 5 is connected to the hollow needle tube 2, and the sealing gasket 14 can improve the sealing between the first connecting block 3 and the second connecting block 4 to prevent the leakage of the irrigation fluid. When the irrigation head 1 needs to be disassembled for cleaning and disinfection, the first connecting block 3 and the second connecting block 4 are pulled with a little force to make the limit block 9 squeeze the arc-shaped block 12 again, so that the arc-shaped block 12 can be separated from the arc-shaped slot 10, which is convenient to operate. Then the irrigation head 1 is inserted into the animal irrigation part, and then the syringe is connected to the syringe connector 7. The irrigation fluid is injected into the connecting hose 5 through the syringe, and then enters the animal body from the irrigation head 1 through the hollow needle tube 2, so as to facilitate the irrigation operation.

[0022] The working principle of a laboratory nasal and lung lavage device provided by the utility model is as follows:

[0023] When in use, first connect the connecting hose 5 with the hollow needle tube 2, then insert the lavage head 1 into the lavage part of the animal, then connect the syringe with the syringe connector 7, inject the lavage fluid into the connecting hose 5 through the syringe, and then enter the animal's body from the lavage head 1 through the hollow needle tube 2, thereby achieving the purpose of lavage without causing any damage to the animal's body tissues.
