Detailed Description

The core of the utility model is to provide a fixer, this fixer can block or loosen interior sleeve pipe as required, and does not receive the influence that the patient coughed. Also provides a tracheal cannula applying the fixator.

Please refer to fig. 1 to fig. 2.

In a specific embodiment, the present invention provides a fixer, which comprises a shell 1 and a baffle 2; the shell 1 is fixedly connected to the outer sleeve 4 and close to the inner sleeve 5, the shell 1 is of a cuboid shell-shaped structure, the first end of the shell is an open end, and the side surface of the shell 1 is provided with a strip-shaped opening 11 along the length direction; the baffle 2 is inserted at the first end of the shell 1, and one end of the baffle 2 extending into the shell 1 is connected with the inner side wall of the second end of the shell 1 through a pressure spring 3; the baffle 2 is provided with a T-shaped handle 24 which penetrates through the strip-shaped opening 11 and extends out of the shell 1, and the baffle 2 can be driven to retract into the shell 1 to enable the inner sleeve 5 to be out of limit by moving the handle 24 along the strip-shaped opening 11 towards the second end of the shell 1, so that the inner sleeve 5 can be taken out of the outer sleeve 4; or by releasing the handle 24, the baffle 2 can be ejected out of the shell 1 under the action of the compression spring 3 to clamp the inner sleeve 5 again, so that the inner sleeve 5 is prevented from being pulled out of the outer sleeve 4.

Furthermore, a chamfer 21 with an inclined surface facing the inner sleeve 5 can be arranged at one end of the baffle 2 extending out of the shell 1, so that when the inner sleeve 5 is inserted into the outer sleeve 4, the end part of the inner sleeve 5 can gradually extrude the baffle 2 along the inclined surface of the chamfer 21 to enter the outer sleeve 4, the baffle 2 does not need to be pulled open manually, and the use is simple and convenient.

Furthermore, in order to make the baffle 2 slide more stably and smoothly, the strip-shaped sliding grooves 12 extending along the length direction of the shell 1 can be formed in the upper inner side wall and the lower inner side wall of the shell 1, the upper side surface and the lower side surface of the baffle 2 are correspondingly provided with sliding strips 22 connected in the sliding grooves 12, the baffle 2 is not easy to shake due to the matching of the sliding strips 22 and the sliding grooves 12, and the baffle 2 is moved with labor conservation.

On the basis, an arc notch 23 can be formed in the end part of the baffle 2, which extends out of the shell 1, and the diameter of the arc notch 23 is the same as the outer diameter of the inner sleeve 5, so that the baffle 2 is not easy to collide to damage the inner sleeve 5 when being popped up.

Please refer to fig. 3 and 4.

In a specific embodiment, the utility model provides a tracheal cannula, which comprises an outer cannula 4, an inner cannula 5 and a gasket 6; the outer sleeve 4 is provided with a bottom plate 41, the inner sleeve 5 is inserted into the outer sleeve 4, the inner sleeve 5 is provided with an annular flange 51, and the annular flange 51 is provided with a pipe taking notch 511; the gasket 6 is rotatably sleeved on the inner sleeve 5 between the bottom plate 41 and the annular flange 51, and a side surface of the gasket 6 facing the annular flange 51 is provided with a limit hook 61 which can pass through the pipe taking gap 511 and clamp the annular flange 51; on the base plate 41, on both sides of the inner sleeve 5, there is welded a holder, which is the holder in the above embodiment.

Specifically, the distance between the baffle 2 and the bottom plate 41 is equal to the sum of the thicknesses of the gasket 6 and the annular flange 51, so that after the baffle 2 is ejected out of the shell 1 to clamp the inner sleeve 5, the inner sleeve 5 can be prevented from shaking back and forth along the outer sleeve 4 to stimulate the trachea of a patient.

In actual operation, firstly, the gasket 6 is rotated to enable the limiting hook 61 to correspond to the pipe taking notch 511 and align the inner sleeve 5 with the outer sleeve 4, then the end part of the inner sleeve 5 gradually pushes the baffle 2 away along the inclined surface of the chamfer 21 and enters the outer sleeve 4 until the annular flange 51 pushes the baffle 2 away and the limiting hook 61 passes through the pipe taking notch 511, at the moment, the baffle 2 loses limitation, so that the spring shell 1 is ejected out under the elastic restoring force of the pressure spring 3 and finally is blocked at one side of the annular flange 51 to clamp the inner sleeve 5, and the inner sleeve 5 is prevented from being pulled out of the outer sleeve 4; when the inner sleeve 5 needs to be taken out, the thumb and the forefinger are used for stretching the two handles 24, the corresponding baffle plates 2 are respectively driven to retract into the shell 1, the annular flange 51 of the inner sleeve 5 is not limited, then the gasket 6 is rotated to enable the limiting hook 61 to correspond to the position of the pipe taking notch 511, and then the inner sleeve 5 is taken out.
