Description
Technical field
The utility model belongs to technical field of medical instruments, and in particular to a kind of fixator for tracheal cannule.
Background technology
Mechanical ventilation plays an important roll in critical illness rescue, and trachea cannula abjection is more serious in mechanical ventilation
One of complication.Trachea cannula abjection is probably patient's voluntarily tube drawing, it is also possible to is pulled out outside medical care path is favorite.Once
Generation trachea cannula slips, and can cause the injury again to patient, such as non-timely processing, can cause patients acuity anoxic, even
Asphyxia, death.Tracheal catheter is kept not to be shifted over, come off in fixed position after trachea cannula success, currently used for fixation
The method of trachea cannula is typically after it is determined that being intubated successfully, bite-block is inserted between the front tooth up and down of patient, with adhesive plaster by gas
Cannula is fixed with bite-block strapped side by side, and trachea cannula is finally fixed on to the Face and cheek of patient with adhesive plaster, and this conduit is fixed
Method has the following disadvantages：First, adhesive plaster viscosity easily weakens or lost, so that connection is insecure, conduit easily releases, misplaced；2nd, lead
Pipe position is not easy to adjust its insertion depth as needed after fixing；3rd, it is not easy to the phlegm that medical personnel are cleared up in patient's mouth
Liquid；4th, being pasted using adhesive plaster can make some patients appearance allergic.
Occurs special tracheal cannula fixer in recent years, bite-block can be used for intubation supporting tooth in fixator
Face is stung, prevents patient to sting flat trachea cannula to ensure that patient respiratory is unobstructed, bite-block can be additionally used in the oral cavity shield of comatose patient in addition
Reason.Chinese invention patent such as Application No. 201010122424.7 discloses a kind of tracheal cannula fixer, including tracheae is inserted
Manage and axially penetrate through the Occluding device main body of through hole, in addition to be provided with the axial direction of the lateral surface in Occluding device main body and embed tracheae
One of groove of intubation, is provided with a pair of jacks, the jack inserts a spring clip, and exists again on one end of Occluding device main body
It is hole that the both sides of a pair of jacks of Occluding device main body, which are arranged with two,.The occlusion position of above-mentioned Occluding device main body is provided with twice pair
The groove of title；Above-mentioned Occluding device main body is that both ends are thick, middle thin waist drum shape, and the length of the Occluding device main body is 70-80mm, mouth
Containing end a diameter of 25mm, a diameter of 30mm of the other end.The tracheal cannula fixer of the utility model can not be changed arbitrarily, be unfavorable for
Oral care；Spring clip is used to fix trachea cannula, exists situations such as connection is insecure, and conduit is easily released, misplaced and occurs.
Utility model content
