Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

In the present invention, the terms "upper", "lower", "left", "right", "middle" and "one" are used for clarity of description, but not for limiting the range of the present invention, and the relative relationship changes or adjustments without substantial technical changes should be regarded as the scope of the present invention.

In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

Referring to fig. 1-2, disposable laryngeal mask airway tube, including breathing machine 1, installing port 2 that is linked together with inside is seted up to breathing machine 1 lateral wall, slidable mounting has pipe 3 in installing port 2, a plurality of draw-in grooves 4 have been seted up in installing port 2, the pipe 3 outer wall is equipped with the latch mechanism 5 that is used for using with draw-in groove 4 cooperation, latch mechanism 5 includes a plurality of installation pieces 51, installation piece 51 and pipe 3 outer wall fixed connection, installation piece 51 articulates there is dwang 52, surface fixed mounting has joint pole 53 on the one end that installation piece 51 was kept away from to dwang 52, many dwang 52 slide to cup joint ring 54, be equipped with canceling release mechanical system 6 that is used for dwang 52 to reset between pipe 3 outer wall and the dwang 52.

In the embodiment applying the above technical solution, when the worker needs to replace the catheter 3, as long as the ring 54 is pushed towards the ventilator 1, the plurality of rotating rods 52 will rotate around the hinged position with the mounting block 51, and at this time, the reset mechanism 6 will be squeezed, so that the clamping rod 53 will move in the clamping groove 4, until the clamping rod 53 rotates to be taken out from the clamping groove 4, at this time, the catheter 3 is drawn out of the respirator 1 and the pushing of the ring 54 is stopped, the reset mechanism 6 drives the rotating rod 52 to reset rapidly, the installation process is simple, the ring 54 is pushed to the respirator 1, the pushing of the ring 54 is stopped until the clamping rod 53 can be clamped with the clamping groove 4, when the acting force on the reset mechanism 6 disappears, the reset mechanism 6 can quickly drive the rotating rod 52 to reset, so that the clamping rod 53 and the clamping groove 4 are fixedly clamped.

In the preferred technical solution of this embodiment, the reset mechanism 6 includes an arc-shaped telescopic rod 61 using the hinged position of the mounting block 51 and the rotating rod 52 as a circle center, a spring 62 is fixedly mounted in the telescopic rod 61, and two ends of the telescopic rod 61 are respectively fixedly connected with the outer wall of the catheter 3 and the surface of the rotating rod 52. When the ring 54 is pushed, the rotating rod 52 rotates around the hinge, so that the telescopic rod 61 is squeezed and contracted, and when the squeezing force disappears, the spring 62 can rapidly drive the rotating rod 52 to return.

In the preferred technical solution in this embodiment, the inner ring of the circular ring 54 is provided with a spherical groove 7, a ball 8 is embedded in the spherical groove 7 in a rolling manner, the surface of the rotating rod 52 is provided with a limiting groove 9, and the ball 8 is in rolling contact with the groove wall of the limiting groove 9. The spherical ball 8 reduces the frictional force generated when the annular ring 54 is brought into sliding contact with the surface of the rotating lever 52.

In the preferred technical scheme in this embodiment, a first magnetic block 10 is fixedly mounted at one end of the clamping rod 53 far away from the rotating rod 52, a second magnetic block 11 is fixedly mounted at the bottom of the groove in the clamping groove 4, and the magnetic poles of the surfaces of the first magnetic block 10 and the second magnetic block 11 close to each other are opposite. When the clamping rod 53 is clamped into the clamping groove 4, the first magnetic block 10 and the second magnetic block 11 are mutually attracted under the action of opposite attraction, so that the stability of the catheter 3 in clamping connection with the respirator 1 is improved.

In the preferred technical scheme in this embodiment, the groove wall of the clamping groove 4 far from the mounting block 51 is connected with the wall of the opening of the mounting opening 2 through an arc surface. Because the rotating rod 52 can drive the clamping rod 53 to rotate in the mounting and dismounting processes, a certain space is reserved on the arc surface to enable the arc surface to rotate, and the clamping situation cannot occur.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
