Description
Technical field
The invention belongs to the field of medical instrument technology, the trachea cannula conduit support of specifically a kind of safety convenient
Device and sputum-suction trachea cannula.
Background technique
Trachea cannula, which refers to, is known as trachea cannula through the technology of glottis merging person's windpipe for endotracheal tube, this technology
It can attract for airway patency, ventilation oxygen-supplying, respiratory tract and prevent accidentally suction etc. from providing optimum condition.
Emergency trachea intubation has become CPR and rescues process with the Severe acute disease patient of respiratory dysfunction
In important measures.Endotracheal intubation is common important rescue technology in rescue service, is most widely used in management of respiratory
General, most effective, most efficiently one of means, to rescue patient vitals, reduce case fatality rate play the role of it is vital.
Mechanical ventilation critical illness rush-harvest in county play an important role, it be CPR, paralysis of respiratory muscle, surgery anesthesia and
Most popular method in open airway, trachea cannula abjection is one of complication more serious in mechanical ventilation, once gas occurs
Cannula slips, and such as handles not in time, can lead to patient's acute anoxia, or even asphyxia, death.Intubation will cause to patient again
Injury again, also will increase the economic negative twist of patient, so to keep tracheal catheter in fixed position after trachea cannula success
It is not displaced, falls off.
Clinically, trachea cannula operation is carried out to patient, in the fixator of use, for a long time with pipe using H-type adhesive plaster
Compare more, is in addition exactly mask type.Fixator, which is placed on mouth, can force pain of dehiscing, and bite-block is mostly that straight type double-vane is placed on oral cavity
Positive middle part is easy to compressing lip and gum, the patient that left and right is loosened without supporting point, especially front tooth, tooth is sparse, tooth in this way
Pad and conduit cannot be mutually integrated in oral cavity；Oral cavity is persistently in force to magnify state, and oral cavity facial muscles are extremely tired to ache.
Butterfly H shape is fixed on the facial muscular tone of adhesive plaster meeting of Face and cheek, and somebody understands cloth hypersensitivity, and long-time service damages skin
Wound.
Effect is preferably similar to mask, is open in mouth position, support device is protruded into mouth, pries open tooth, then
Hollow position among supporting mechanism protrudes into conduit.The problem of encountering under which mainly has: the use of time, the tongue of patient
Head can contact conduit；In catheterization procedure, if encountering unconscious patient, the mandibular joint for needing to pry open patient is put into conduit support machine
Structure, operation are relatively difficult.
Summary of the invention
In order to solve the above-mentioned problems in the prior art, the invention proposes a kind of trachea cannula of safety convenient
With vessel supporting devices, including air bag and conduit bindiny mechanism；
Under entirely pneumatic state: the shape of air bag is pears type, and the larger side of pears type air bag is towards the tracheae side of human body
To；Be provided with the through-hole that is passed through with conduit of gas supply cannula on pears type air bag, the axis of through-hole it is parallel with the axis of pears type air bag or
It is overlapped；
Conduit bindiny mechanism is cylindrical shape, and the material of conduit bindiny mechanism is hard；The end of conduit bindiny mechanism
The input end of end connection through-hole, the hollow of conduit bindiny mechanism are connected to through-hole inner cavity；Conduit is telescopically through conduit
Bindiny mechanism it is hollow in；
The air inflation nozzle of air bag is by piping connection on air bag；The main body of pipeline is located on the wall of conduit bindiny mechanism, gas
For the import/exhaust mouth of capsule by the input end of through-hole, pipeline one end connects the import/exhaust mouth of air bag.
The main body of pipeline can be in the wall of catheter body bindiny mechanism.
The principle of the invention is that the air bag under air deflating state is put into disease population, and inflation obtains the air bag of pears type,
Fill up patient's mouth.Air bag at this time is difficult to population taking-up.The through-hole of air bag is used to perforate pipe.Mouth, tongue of patient etc. will not touch
And conduit.Also without other structures for fixing outside air bag.After use, after air bag is deflated, taken out from population
?.The invention can be disposable.
As an improvement, the material of the air bag is elastomeric material.The higher patient of the structure degree of being adapted for engagement with, and for
The unconscious equal lower patient of fitnesss, can be improved using following structure:
The material of the air bag is inelastic plastic foil；It further include air bag wrapping layer；Air bag wrapping layer includes multi-disc item
The screening glass of shape, screening glass are the flexible plastic sheets for being enclosed with the hard of layer of silica gel；Each screening glass is all attached to the table of air bag
Face；The terminal position of each screening glass is in the outlet end of through-hole, the input end of the head end position of each screening glass in through-hole；It is filling
It is plastic foil between adjacent screening glass under gaseity；Under non-aerating state, the screening glass outside air bag main body is smooth, multiple
Screening glass is divided into upper layer and lower layer.
The main body of air bag under air deflating state is flat pattern, and plastic foil is crushed on screening glass bottom at irregular folding state
Side.Under the protection of screening glass, the balloon surface under air deflating state is hard, can be filled in mouth from patient's mandibular joint, then fill
Gas, after air bag bulges, forming through holes, then catheter body protruded into from through-hole the through-hole of air bag, and then be put into tracheae.In air bag
After bulging, the plastic foil that originally straight screening glass is formed is jacked up, and the spacing between adjacent screening glass increases, folding originally
State is expanded into formation state.
As advanced optimizing, the air bag includes upper and lower two parts, under entirely pneumatic state:
Upper part air bag and lower part air bag piece together complete pears type air bag；The bottom surface and lower part of the upper part air bag
The top surface of air bag is divided to be designed with bar shaped indent, two bar shaped indents piece together complete through-hole.
Under entirely pneumatic state, the volume of upper part air bag is greater than the volume of lower part air bag, the axis runout of through-hole
The axis of pears type air bag.Upper part air bag be against oral cavity it is big a bit, lower part air bag is against lingual surface, more flat, small
A bit.
It further include mask type fixator；Mask type fixator includes frenulum and mask；Frenulum is connected on mask side；Mask
On be provided with circular hole, conduit bindiny mechanism is connected on circular hole, and circular hole is coaxial with the through-hole.
Production and the use of time, trachea cannula can be with conduit it is independent, conduit pass through through-hole.It is also possible to
Trachea cannula vessel supporting devices and trachea cannula collectively form sputum-suction trachea cannula with conduit and are produced and used, this
When, the connection type between conduit and conduit bindiny mechanism are as follows:
A kind of mode be the conduit bindiny mechanism head end and conduit outer wall between be connected with plastic film.Which
Under, the range of protrusion of conduit is defined by the length of plastic film.
Another way is that the conduit is externally provided with multiple parallel annular ridges, on the inner wall of the conduit bindiny mechanism
Equipped with corresponding annular ridge.Conduit is limited with conduit bindiny mechanism by annular ridge.
The invention, safety convenient can be disposable.
