Description

Tracheal cannula fixer commonly used for anesthesia

Technical Field

The utility model belongs to the technical field of medical instrument, especially relate to a trachea cannula fixer commonly used for anesthesia.

Background

During certain surgical procedures, general anesthesia is performed using a tracheal cannula inserted into the oral cavity. At present, no special device for fixing the anesthetic trachea exists clinically, the trachea cannula is placed in a natural state after being inserted, and the operation has the defects that: the tracheal cannula is not firmly fixed, and if the tracheal cannula is carelessly displaced, great danger is brought to a patient.

Therefore, how to solve the above technical problems becomes a focus of research by those skilled in the art.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a trachea cannula fixer commonly used for anesthesia, which can completely solve the defects of the prior art.

The purpose of the utility model is realized through the following technical scheme:

the utility model provides a trachea cannula fixer that anesthesia was used commonly, includes stand, swivel nut and clamping part, the swivel nut screw thread cup joints on the stand, the clamping part includes two bracing pieces that articulate in the stand top and connects in every relative semicircle portion on the bracing piece, two the bracing piece between be connected with the spring, the swivel nut is in-process up rotating, can fold two bracing pieces and make two semicircle portion closes the whole circle portion of centre gripping trachea cannula's centre gripping of formation.

Further, a cushion layer is bonded on the inner side wall of the semicircular part.

Furthermore, the outer wall of the threaded sleeve is provided with an anti-skidding protection pad.

Further, be fixed with the adapter sleeve on the stand, it has the landing leg to articulate on the adapter sleeve, the below that lies in the adapter sleeve on the stand is provided with the sliding sleeve, it has the assistance landing leg to articulate on the sliding sleeve, the one end that the sliding sleeve was kept away from to the assistance landing leg with the landing leg is articulated, follows the sliding sleeve slide from top to bottom on the stand, can pass through the assistance landing leg will the landing leg is opened or is foldd.

Compared with the prior art, the beneficial effects of the utility model reside in that:

the utility model discloses simple structure, reasonable in design folds the clamping part to the centre through the thread bush with the up rotating of thread bush, is two semicircle portions and merges into centre gripping trachea cannula's whole circle portion for trachea cannula is fixed stable, does not drop and shift, guarantees that the anesthesia process goes on smoothly.

Detailed Description

The invention will be further described with reference to the following specific embodiments and the accompanying drawings.

As shown in fig. 1 to 2, a tracheal cannula fixer commonly used for anesthesia comprises an upright post 1, a threaded sleeve 2 and a clamping part 3, wherein the upright post 1 can be inserted into an insertion hole on a hospital bed and can also be fixed on the bottom surface, an external thread is arranged at the upper end of the upright post 1, the threaded sleeve 2 is sleeved at the upper end of the upright post 1, two sets of hinge seats 4 which are oppositely arranged are integrally formed on the top of the upright post, and the hinge parts 3 are hinged and installed on the hinge seats 4 through pivots, specifically: the clamping part 3 comprises two support rods 301 and opposite semicircular parts 302 welded on each support rod 301, a spring 303 is welded between the two support rods 301, the screw sleeve 2 is rotated upwards in the using process, and the two support rods 301 are folded to enable the two semicircular parts 302 to be combined to form a clamping round part for clamping the tracheal cannula in the ascending process of the screw sleeve 2, so that the tracheal cannula is fixed to be stable and not to be displaced or fall off; when taking out the trachea, the screw sleeve 2 slides downwards, the supporting rod 301 is unfolded towards two sides under the action of the spring 303, and the trachea cannula can be loosened.

In order to prevent the semicircular part 302 from strongly pressing the endotracheal tube during the clamping process, a cushion layer (not shown in the figure) is bonded on the inner wall of the semicircular part 302, and the endotracheal tube is prevented from shaking;

in order to prevent the screw sleeve 2 from slipping in the rotating process, an anti-slip protection pad is bonded on the outer wall of the sliding sleeve 2, and meanwhile, the function of protecting hands and preventing hands from being injured is achieved;

in order to ensure that the upright post is stably placed on the bottom surface without toppling over, the lower middle part of the upright post 1 is sleeved with the connecting sleeve 5 in an interference manner, the connecting sleeve 5 is hinged with the supporting legs 6, the preferred number of the supporting legs 6 is three, the supporting stability is the best, the upright post 1 is positioned below the connecting sleeve 5 and is sleeved with the sliding sleeve 7 in a sliding manner, the sliding sleeve 7 is hinged with the auxiliary supporting legs 8, one end, far away from the sliding sleeve 7, of the auxiliary supporting legs 8 is hinged with the supporting legs, in the using process, the sliding sleeve 7 slides upwards, the supporting legs 6 are supported outwards through the support of the auxiliary supporting legs 8, in order to prevent the sliding sleeve 7 from moving downwards in the using process, the sliding sleeve 7 is fixed with the first magnetic block 9 through screws, the upright post 1 is fixed with the second magnetic block 10 mutually attracted with the first magnetic block 9 through screws, the sliding sleeve 7 is not slid downwards, and when the upright post is not, the supporting legs 6 are folded, and the space is not occupied.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
