Description

Technical Field

[0001] This utility model relates to the field of quick-connect fittings, and in particular to a double-sealed quick-connect fitting for endotracheal tubes. Background Technology

[0002] Quick connectors are the most convenient plug-and-play connection method, and their superiority is especially evident in situations where air pipe connections are inconvenient or difficult.

[0003] However, existing quick-connect fittings generally only have a simple single seal, resulting in poor overall sealing and reduced overall device sealing. Furthermore, existing connections between air tubes and quick-connect fittings generally lack limiting devices, making it impossible to guarantee the stability of the connection between the air tube and the quick-connect fitting. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology. By using the connecting pipe to transport the air into the air ring, the air ring expands and seals the gap between the connecting cylinder and the air pipe body again, thereby achieving a secondary seal on the connector body and improving the overall sealing performance of the device. This invention proposes a double-sealed quick-connect air pipe connector.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A double-sealed quick-connect endotracheal connector includes a connector body, a connecting cylinder extending through the connector body, a connecting tube at the end of the connecting cylinder, a sealing groove at the bottom of the connecting cylinder, a sealing ring inside the sealing groove, a fixing ring at the front end of the connecting cylinder, an endotracheal body above the fixing ring, a limiting groove on the outer wall of the endotracheal body, a limiting mechanism on the outer wall of the fixing ring for limiting the endotracheal body, and a sealing mechanism on the inner wall of the connecting cylinder for secondary sealing of the endotracheal body.

[0007] Preferably, the limiting mechanism includes a plurality of symmetrically arranged grooves on the outer wall of the fixed ring, and a rotating shaft is rotatably connected to each of the plurality of grooves. Damping pads are provided at the rotatable connection points between the rotating shafts and the grooves.

[0008] Preferably, the sealing mechanism includes a placement groove formed on the inner wall of the connecting cylinder, the placement groove being annularly arranged, and an air ring being provided inside the placement groove.

[0009] Preferably, each of the multiple rotating shafts has a connecting block on its outer wall, a connecting plate on its side wall, and a limiting plate at its upper end, which cooperates with a limiting groove.

[0010] Preferably, a connecting pipe is provided between the connecting pipe and the connecting cylinder, and the connecting pipe is U-shaped.

[0011] Preferably, one end of the connecting pipe located inside the connecting pipe is provided with a one-way valve, and the other end of the connecting pipe is connected to the air ring.

[0012] The beneficial effects of this utility model are:

[0013] 1. After being transported through the connecting pipe, it enters the air ring, causing the air ring to expand and reseal the gap between the connecting cylinder and the air pipe body, thus achieving a secondary seal on the joint body and improving the overall sealing performance of the device.

[0014] 2. By rotating the connecting plate along with the limiting plate, multiple limiting plates are inserted into the limiting groove, thereby restricting the connection between the connector body and the air pipe body and improving the stability of the connection. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] Reference Figure 1-3A double-sealed quick-connect endotracheal connector includes a connector body 1, a connecting cylinder 2 extending through the connector body 1, a connecting tube at the end of the connecting cylinder 2, a sealing groove 15 at the bottom of the connecting cylinder 2, a sealing ring 16 inside the sealing groove 15, a fixing ring 5 at the front end of the connecting cylinder 2, an endotracheal body 6 above the fixing ring 5, a limiting groove 7 on the outer wall of the endotracheal body 6, and a limiting mechanism on the outer wall of the fixing ring 5 for limiting the endotracheal body 6. The limiting mechanism includes multiple symmetrically arranged grooves 8 on the outer wall of the fixing ring 5, each groove 8 being rotatably connected to a rotating shaft 14, and damping pads at the rotatable connection points between the rotating shaft 14 and the grooves 8.

[0022] The inner wall of the connecting cylinder 2 is provided with a sealing mechanism for secondary sealing of the air pipe body 6. The sealing mechanism includes a placement groove 12 opened on the inner wall of the connecting cylinder 2. The placement groove 12 is arranged in a ring and an air ring 13 is provided in the placement groove 12.

[0023] Multiple rotating shafts 14 are provided with connecting blocks 9 on their outer walls. Connecting plates 10 are provided on the side walls of the connecting blocks 9. Limiting plates 11 are provided at the upper end of the connecting plates 10. The limiting plates 11 cooperate with the limiting grooves 7. By rotating the connecting plates 10 with the limiting plates 11, multiple limiting plates 11 are extended into the limiting grooves 7, thereby restricting the connection between the connector body 1 and the air pipe body 6 and improving the stability of the connection between the two.

[0024] A connecting pipe 3 is provided between the connecting pipe and the connecting cylinder 2, and the connecting pipe 3 is U-shaped.

[0025] One end of the connecting pipe 3 is equipped with a one-way valve 4, and the other end of the connecting pipe 3 is connected to the air ring 13. After being transported by the connecting pipe 3, it enters the air ring 13, causing the air ring 13 to expand and seal the gap between the connecting cylinder 2 and the air pipe body 6 again, thereby achieving a secondary seal on the connector body 1 and improving the overall sealing performance of the device.

[0026] When using this utility model, when connecting the trachea body 6 and the connector body 1, the trachea body 6 is inserted into the connecting tube 2 and contacts the sealing ring 16 at the end of the connecting tube 2. The sealing ring 16 is used to initially seal the connecting tube 2 and the trachea body 6.

[0027] At this time, by utilizing the rotational connection between the rotating shaft 14 on the connecting block 9 and the groove 8 (the damping pad restricts the position of the rotating shaft 14 after rotation), multiple connecting plates 10 are rotated respectively, so that the connecting plates 10 rotate with the limiting plates 11, and so that multiple limiting plates 11 extend into the limiting groove 7, thereby restricting the connection between the connector body 1 and the air tube body 6 and improving the stability of the connection between the two.

[0028] After the air tube body 6 is connected to the connector body 1, air is introduced into the connector body 1. Under the action of the one-way valve 4 in the connecting pipe 3, the gas enters the connecting pipe 3 through the one-way valve 4. After being transported by the connecting pipe 3, the gas enters the air ring 13, causing the air ring 13 to expand and seal the gap between the connecting cylinder 2 and the air tube body 6 again, thereby achieving a secondary seal on the connector body 1 and improving the overall sealing performance of the device.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
