Detailed Description
The present invention is further described in detail below with reference to examples so that those skilled in the art can implement the invention with reference to the description.
It will be understood that terms such as "having," "including," and "comprising," when used herein, do not preclude the presence or addition of one or more other elements or groups thereof.
As shown in fig. 1-2, a transnasal tracheal cannula with an adjustable front end angle comprises a transnasal tracheal cannula body 2, wherein a traction steel wire 1 is arranged on the inner side wall of the transnasal tracheal cannula body, a first adjusting device 3 is arranged on the inner side of the near front end of the transnasal tracheal cannula body, a through hole 310 is arranged on one side of the first adjusting device, a second adjusting device 4 is fixed on the inner side wall of the transnasal tracheal cannula body below the first adjusting device, and a threaded hole 410 is arranged at the position of the second adjusting device 4 corresponding to the through hole 310; first adjusting device and second adjusting device accessible technologies such as integrative injection moulding fix on intranasal trachea cannula body.
The upper end of the traction steel wire penetrates through the through hole and the threaded hole, and the upper end of the traction steel wire is rotatably connected with the through hole; the surface of the upper part of the traction steel wire is provided with an external thread matched with the threaded hole; through the relative position between rotatory traction wire adjustment first adjusting device and the second adjusting device, force intranasal trachea cannula body front end to one side slope to realize the regulation of intranasal trachea cannula body front end angle. The first adjusting device and the second adjusting device can be arranged in parallel or at a certain included angle.
The traction steel wires on the upper side and the lower side of the through hole are provided with protrusions 110, so that the upper ends of the traction steel wires can be rotatably limited in the through hole; this allows the distance between the through hole and the threaded hole to be increased or decreased by rotating the upper end of the traction wire, so that the front end of the transnasal endotracheal tube can be tilted or bent leftward or rightward in one plane.
The first adjusting device and the second adjusting device are ring bodies which are fixed on the inner side wall of the transnasal trachea cannula body in a nested mode.
The through hole is formed by a small ring 320 provided on the inner side wall of the first adjustment means.
The threaded hole is formed by a small nut 420 fixed to the inner side wall of the second adjustment means.
The lower end of the traction steel wire penetrates through the side wall at the rear part of the transnasal tracheal intubation body and is led out to the outside of the transnasal tracheal intubation body.
The lower end of the traction steel wire is provided with an adjusting rod 120 which can be manually operated or connected with an electric device to rotate the traction steel wire.
The wall thickness of the semi-circumference part of the transnasal tracheal intubation body between the side of the through hole and the threaded hole is smaller than that of the circumference part. This makes the nose-mounted endotracheal tube more prone to bending when the distance between the through hole and the threaded hole is changed.
The first adjusting device is arranged 2-6cm away from the front end of the transnasal tracheal cannula. First adjusting device has certain distance apart from intranasal trachea cannula front end, and this makes the relative position between first adjusting device and the second adjusting device only need change by a small margin, can drive intranasal trachea cannula front end position and produce change by a large margin.
When the transnasal tracheal cannula is inserted, the adjusting rod is manually or connected with the motor, and the adjusting rod is rotated to drive the traction steel wire to rotate, so that the relative position (included angle or one-side distance) between the second adjusting device and the first adjusting device is changed, and the front end of the transnasal tracheal cannula can swing left and right in a set plane so as to be conveniently inserted in alignment with the glottis; when the distance between through-hole and the screw hole reduces, pernasal trachea cannula front end is crooked to being close to through-hole one side, and when the distance between through-hole and the screw hole increases, pernasal trachea cannula front end is crooked to keeping away from through-hole one side.
While the embodiments of the invention have been disclosed above, it is not limited to the applications listed in the description and the embodiments, which are fully applicable in all kinds of fields suitable for the invention, and further modifications may be readily made by those skilled in the art, and the invention is therefore not limited to the specific details and embodiments shown and described herein, without departing from the general concept defined by the claims and their equivalents.
