The utility model relates to the technical field of medical appliances, in particular to trachea cannula fixer.

[ background of the invention ]

In the rescue process of patients with serious diseases, tracheal intubation is basically required. At present, most of fixing methods of the tracheal cannula are that a bite block and the tracheal cannula are fixed by adhesive tapes and then directly adhered to the cheek of a patient, and long-term clinical experiments prove that the fixing method has many defects: for example, the fixing mode of the tracheal intubation is unstable, the tracheal intubation has great mobility, and the tracheal intubation is easy to fall off or is too deep, so that great harm is caused to patients, and further serious medical accidents are caused.

Based on the above problems, there is a need for a tracheal cannula fixator with good effect.

[ Utility model ] content

In order to overcome the defects of the prior art, the utility model aims to provide a tracheal cannula fixer, this tracheal cannula fixer simple structure can carry out dual fixed to tracheal cannula, and the fixity is good, still can prevent simultaneously that the patient from weighing down behind the tongue root, avoids the tongue to stop up the throat completely, is convenient for in addition use with the cooperation of saliva drainage device, and the practicality is strong.

In order to achieve the above purpose, the utility model adopts the technical proposal that:

a trachea cannula fixer comprises a fixer body and fixing belts arranged at two ends of the fixer body, wherein a mouth corner through hole is formed in the position, corresponding to a mouth corner of a human body, of the fixer body, a fixing sheet is arranged in the middle of the fixer body, an inverted U-shaped pipe groove is formed in the fixing sheet, a first limiting transverse rod and a second limiting transverse rod are symmetrically arranged on two sides of the opening end of the inverted U-shaped pipe groove, the first limiting transverse rod and the second limiting transverse rod are both parallel to the fixing sheet and extend towards the opening end of the inverted U-shaped pipe groove, the first limiting transverse rod and the second limiting transverse rod are all made of silica gel, and limiting holes are further formed in the fixing sheet; the auxiliary intubation tube comprises a fixing piece and is characterized by further comprising an auxiliary intubation tube, the head end of the auxiliary intubation tube is detachably connected with the limiting hole and is perpendicular to the fixing piece, the tail end of the auxiliary intubation tube faces the oral cavity direction of a human body, a baffle is arranged at the tail end of the auxiliary intubation tube, a tongue depressor is arranged at the position, close to the baffle, of the auxiliary intubation tube, and the tongue depressor is perpendicular to the auxiliary intubation tube.

Furthermore, the both ends symmetry of fixer body is equipped with the fixed band through-hole, the fixed band passes through the fixed band through-hole with the connection can be dismantled to the fixer body.

Furthermore, a moisture absorption layer is arranged on the nozzle corner through hole and surrounds the nozzle corner through hole.

Further, the shape of the nozzle corner through hole is heart-shaped or circular.

Furthermore, the limiting hole is internally provided with an internal thread, the head end of the auxiliary insertion tube is provided with an external thread matched with the internal thread, and the limiting hole and the auxiliary insertion tube are connected through the internal thread and the external thread.

Furthermore, the limiting hole, the first limiting cross rod and the second limiting cross rod are located on the same horizontal line.

Owing to used the technical scheme of the utility model, the utility model discloses following beneficial effect has:

(1) when the trachea cannula fixing device is used, the trachea cannula is pushed into the inverted U-shaped limiting cross rod from the middle of the first limiting cross rod and the second limiting cross rod by applying force, the first cross rod and the second cross rod are stressed to be folded towards the inverted U-shaped tube groove direction, so that the trachea cannula is placed into the inverted U-shaped tube groove, the force application is stopped, at the moment, the first cross rod and the second cross rod rebound to block the opening end of the inverted U-shaped tube groove, and the trachea cannula is stabilized in the inverted U-shaped tube groove, so that the trachea cannula is effectively prevented from being taken off, the structure is simple, and the fixation is good; further, the inserting of supplementary intubate has increased the volume of the insert in the patient's oral cavity on the one hand, has reduced trachea cannula mobilizable scope, and on the other hand can play limiting displacement at the baffle of tail end, can effectively avoid trachea cannula to receive external force effect to the internal slip of patient so that trachea cannula inserts too dark phenomenon, consequently, the spacing chase of falling U combines with supplementary intubate, can be to trachea cannula its to dual fixed action, the steadiness height. In addition, the tongue of patient can be pushed down to the tongue depressor of supplementary intubate, avoids patient's tongue back to weigh down, leads to the tongue to all block up the throat and the unable exhaust phenomenon of saliva, has promoted the security that trachea cannula put into.

(2) The mouth angle through-hole does benefit to and inserts outside saliva drainage device and carries out the saliva drainage to avoid the saliva of patient's secretion to scatter to chin, neck etc. along the mouth angle overflow, promoted the comfort that the patient used the fixer.

Although there are many studies on the tracheal cannula fixator at present, which is beneficial to the tracheal cannula fixator of chinese patent CN20775561U, although an arc-shaped limiting groove for fixing the tracheal cannula and a hollow tongue-spatula tube cavity for draining saliva and spatula are also disclosed, the structure of the arc-shaped limiting groove is more elaborate and complex, and the hollow tongue-spatula tube cavity therein cannot effectively enhance the stability of the tracheal cannula fixation and has poor spatula effect, and at the same time, it cannot treat saliva overflowing from the corner of the mouth.
