DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Reference Figure 1-Figure 5 A disposable medical suction tube that is easy to connect includes a first pipe 1 and a second pipe 6. A fixing ring 7 is installed on one side of the second pipe 6. A first connecting sleeve 8 is installed on one edge of the fixing ring 7. A support ring 11 is provided on one side of the first connecting sleeve 8. The support ring 11 is connected to the suction device through a pipe, and a second connecting sleeve 10 is installed on one end of the support ring 11 close to the first connecting sleeve 8. The support ring 11 and the second connecting sleeve 10 are stepped. One end of the second connecting sleeve 10 extends into the inside of the first connecting sleeve 8. By inserting the second connecting sleeve 10 into the first connecting sleeve 8, the second pipe 6 can be connected to the external suction device.

[0026] It should be noted that the first connecting sleeve 8 is made of elastic material. When the second connecting sleeve 10 moves into the first connecting sleeve 8, it will stretch the first connecting sleeve 8, so that the inner wall of the first connecting sleeve 8 and the outer surface of the second connecting sleeve 10 are in close contact, thereby improving the sealing effect.

[0027] like Figure 2 and Figure 3 As shown, at least two elastic connecting pieces 9 are installed at one end of the first connecting sleeve 8 close to the second connecting sleeve 10. The elastic connecting piece 9 is made of elastic plastic. The elastic connecting piece 9 is sleeved on the second connecting sleeve 10. A clamping block 14 is installed on one side of each elastic connecting piece 9. When one end of the second connecting sleeve 10 is against the side of the fixing ring 7, one end of the clamping block 14 contacts the side of the support ring 11. In actual use, after the second connecting sleeve 10 is inserted into the first connecting sleeve 8, the clamping block 14 will move to the other end of the second connecting sleeve 10, and under the action of the elastic connecting piece 9, one end of the clamping block 14 will extend to the step where the second connecting sleeve 10 is connected to the support ring 11, so that the clamping block 14 can be clamped at one end of the second connecting sleeve 10 to prevent the second connecting sleeve 10 from falling off from the first connecting sleeve 8.

[0028] It should be noted that if Figure 3 As shown, the side of the block 14 away from the second pipe 6 is inclined. When the second connecting sleeve 10 moves toward the first connecting sleeve 8, the second connecting sleeve 10 will squeeze the block 14. Under the action of the inclined surface, the block 14 will push the elastic connecting piece 9 toward the outside of the first connecting sleeve 8 to deform, so that the second connecting sleeve 10 will not be stuck by the block 14 during the connection process.

[0029] like Figure 1As shown, a connecting pipe 4 is provided between the first pipe 1 and the second pipe 6, and second threaded sleeves 3 are installed at both ends of the connecting pipe 4, and first threaded sleeves 2 are installed at the proximal ends of the first pipe 1 and the second pipe 6. The second threaded sleeves 3 are respectively sleeved on the corresponding first threaded sleeves 2 and threadedly engaged with the first threaded sleeves 2. Through the cooperation of the first threaded sleeves 2 and the second threaded sleeves 3, the first pipe 1 and the second pipe 6 can be connected together through the connecting pipe 4.

[0030] It should be noted that the first pipe 1 and the second pipe 6 are both made of medical polymer materials, so that during use, the first pipe 1 and the second pipe 6 can be bent as needed.

[0031] like Figure 4 As shown, a connecting ring 5 is installed inside the connecting pipe 4, and a diaphragm 12 is connected to the side of the connecting ring 5 close to the second pipe 6 through a connecting belt 16, and the diaphragm 12 covers one side of the connecting ring 5. In actual use, when absorbing liquid, the flow of the liquid will push up the diaphragm 12, so that one side of the diaphragm 12 is separated from the side of the connecting ring 5, so that the liquid can pass through the connecting pipe 4 and the second pipe 6 and be sucked in by the suction device. When backflow occurs (such as Figure 5 The liquid backflow will exert a thrust on the diaphragm 12, causing the diaphragm 12 to cover the connecting ring 5 and block the connecting pipe 4, thus avoiding backflow.

[0032] It should be noted that the size of the diaphragm 12 is larger than the inner diameter of the connecting ring 5 and smaller than the outer diameter of the connecting ring 5 , so that the diaphragm 12 can block the connecting ring 5 when backflow occurs and will not be hindered by the inner wall of the connecting pipe 4 .

[0033] Specifically, during the installation of the present invention, the staff screws the first threaded sleeve 2 at the end of the first pipe 1 into the second threaded sleeve 3, and then screws the second threaded sleeve 3 at the other end of the connecting pipe 4 with the first threaded sleeve 2 on the second pipe 6, and then moves the first connecting sleeve 8 toward the direction of the second connecting sleeve 10, so that the second connecting sleeve 10 is sleeved on the second connecting sleeve 10. During the connection process, the clamping block 14 is squeezed by the second connecting sleeve 10 and drives the elastic connecting piece 9 to move toward the outside of the first connecting sleeve 8. When the second connecting sleeve 10 moves to the preset position inside the first connecting sleeve 8, the clamping block 1 4 moves to the other side of the second connecting sleeve 10, and the elastic connecting piece 9 recovers its deformation, so that the card block 14 is stuck at the other end of the second connecting sleeve 10, and the connection is completed. The connection is convenient. When in use, when sucking liquid, the liquid will flow along the first pipe 1 to the connecting pipe 4. During the flow, the liquid will lift the diaphragm 12, so that the side of the diaphragm 12 is separated from the side of the connecting ring 5. The liquid can pass through the connecting pipe 4 and flow into the second pipe 6. Finally, the liquid can flow into the suction device. When backflow occurs, the liquid will move from the second pipe 6 to the connecting pipe 4, and the diaphragm 12 is subjected to the pressure of the liquid flow (such as Figure 5 As shown by the arrow in the middle, the diaphragm 12 will cover the side of the connecting ring 5, blocking the connecting pipe 4 to avoid backflow.

[0034] Furthermore, if Figure 3 As shown, at least one sealing ring 13 is installed on the inner side of the first connecting sleeve 8, and at least one sealing groove 15 is opened on the side of the second connecting sleeve 10. When the end of the second connecting sleeve 10 is against the side of the fixing ring 7, the sealing ring 13 is located in the sealing groove 15. During actual use, the sealing ring 13 will move into the sealing groove 15, so that the gap between the first connecting sleeve 8 and the second connecting sleeve 10 can be sealed, thereby improving the sealing effect.

[0035] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
