Description
Technical field
The invention belongs to the field of medical instrument technology, and in particular to a kind of fixator for tracheal cannule.
Background technique
Mechanical ventilation plays a significant role in critical illness rescue, and trachea cannula abjection is more serious in mechanical ventilation
One of complication.Trachea cannula abjection may be patient's voluntarily tube drawing, it is also possible to pull out outside medical care path is favorite.Once
Trachea cannula occurs to slip, will cause the injury again to patient, such as handles not in time, can lead to patients acuity anoxic, even
Asphyxia, death.Tracheal catheter is kept not to be displaced in fixed position, fall off after trachea cannula success, currently used for fixation
The method of trachea cannula is usually to be placed in bite-block between the front tooth up and down of patient, after determining and be intubated successfully with adhesive plaster by gas
Cannula is fixed with bite-block strapped side by side, and trachea cannula is finally fixed on to adhesive plaster the Face and cheek of patient, and this conduit is fixed
Method has the disadvantage in that one, adhesive plaster viscosity easily weakens or loses, so that being not connected firmly, conduit easily loosens, misplaces；Two, it leads
It is not easy to adjust its insertion depth as needed after pipe position is fixed；Three, it is not easy to the phlegm that medical staff clears up in patient's mouth
Liquid；Four, some patients can be made skin allergy occur using adhesive plaster stickup.
Occurs dedicated 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, in addition bite-block can also be used in the oral cavity shield of comatose patient
Reason.Such as application No. is 201010122424.7 Chinese invention patents to disclose a kind of tracheal cannula fixer, including tracheae is inserted
The Occluding device main body for managing and axially penetrating through through-hole further includes being equipped with to embed tracheae in the axial direction of the lateral surface of Occluding device main body
One of groove of intubation is equipped with a pair of of jack on one end of Occluding device main body, which inserts a spring clip, and exists again
It is hole that the two sides of Occluding device main body a pair of jack, which are symmetrically arranged with two,.Twice pair are equipped at the occlusion position of above-mentioned Occluding device main body
The groove of title；Above-mentioned Occluding device main body is the waist drum shape that both ends are thick, centre is thin, and the length of the Occluding device main body is 70-80mm, mouth
The diameter containing end is 25mm, and other end diameter is 30mm.The tracheal cannula fixer of the invention cannot be replaced arbitrarily, and oral cavity is unfavorable for
Nursing；Situations such as spring clip is used to fix trachea cannula, exists and is not connected firmly, and conduit is easily loosened, misplaced appearance.
Summary of the invention
Aiming at the above shortcomings existing in the prior art, the present invention provides the tracheae that a kind of structure is simple, can replace at any time
Insert pipe fixing device.
In order to achieve the above object of the invention, the invention adopts the following technical scheme:
A kind of fixator for tracheal cannule, including upper bite-block and lower bite-block, upper and lower bite-block lid close and form both ends open
Indent is formed on the outer surface of cavity body structure, the size of cavity body structure and the size fit of trachea cannula, upper bite-block or lower bite-block
Pressure lingual surface, upper and lower bite-block realizes that opening for upper and lower bite-block is entire by circular locking member.It is real by circular locking member
Now the opening of upper and lower bite-block and lid close, and so that fixator for tracheal cannule is arbitrarily replaced, conducive to the nursing in oral cavity；Circular
Locking member can also prevent upper and lower bite-block mobile toward cavity interior；The size of cavity body structure and the size fit of trachea cannula and limit
The displacement of trachea cannula processed；The pressure lingual surface that indent is formed on the outer surface of upper bite-block or lower bite-block, adapts to the position of tongue, is promoted
Comfort.
Preferably, the locking member be set to upper and lower bite-block rear end, lock and lock body including semi-annular shape, lock and
The snap-latch surface of lock body is respectively formed an inner groovy, and two inner groovies form the pilot hole of fixed upper and lower bite-block, the size of pilot hole with
The size fit of upper and lower bite-block outer peripheral surface.Upper and lower bite-block is fixed in the pilot hole of locking member, locking member and upper and lower is improved
Assembly stability between bite-block.
Preferably, buckle, the snap-latch surface of lock body are symmetrically laid on the snap-latch surface of the lock centered on the pilot hole
The card slot that upper formation is mutually inserted with buckle.Using the cooperation of buckle and card slot, the quick separating between lock and lock body is realized
And assembly.
Preferably, the contact surface of the upper and lower bite-block forms concave-convex location structure.Upper and lower bite-block, which is set in oral cavity, to be not easy
Observation realizes the assembly positioning of upper and lower bite-block fast and accurately by concave-convex location structure.
Preferably, the contact surface of the upper bite-block forms raised line, and the contact surface of lower bite-block forms mutually matched with raised line
Recessed bar.It by the sliding cooperation of raised line and recessed bar, is moved left and right when limiting the assembly of upper and lower bite-block, avoids encountering oral cavity and cause two
Secondary damage.
Preferably, a layer of silica gel is set on the pressure lingual surface.Layer of silica gel is soft material, good with the compatibility of human body tongue.
Preferably, muscle position is set between pressure lingual surface and the layer of silica gel.The setting enhancing pressure lingual surface and silastic-layer of muscle position
Between the firmness that connects.
Preferably, the pressure lingual surface is plane.Pressure lingual surface is plane, is agreed with the tongue of human body, and comfort is promoted.
Preferably, the company's of being symmetrical arranged cord hole on the locking member.Fixing belt is installed in even cord hole, makes the fixed dress of trachea cannula
It sets and is tightly attached in oral cavity.
Preferably, the front end of the upper and lower bite-block is set as parabola shaped mouth.Parabola shaped mouth agrees with throat mouth, mentions
Rise comfort.
Compared with prior art, the present invention beneficial effect is: fixator for tracheal cannule of the invention passes through upper and lower bite-block
Open it is entire realize fixator for tracheal cannule any replacement, conducive to the nursing in patient oral cavity；The size and tracheae of cavity body structure
The size fit of intubation, contact area to steadily fix trachea cannula, prevent two caused by trachea cannula falls off greatly
Secondary injury；Outer surface in the middle part of upper and lower bite-block forms pressure lingual surface, shields to tongue, promotes comfort；Gas of the invention
Cannula fixture structure is simple, easy to process and quick.
