Description
Technical field
The invention belongs to the field of medical instrument technology, it is related to a kind of nose laryngopharynx surface anesthesia device and its operating method.
Background technique
When clinical anesthesia induces, there are some special circumstances that patient is needed to retain autonomous respiration and the intranasal gas under waking state
Cannula.In order to reduce patient's pain, needing to carry out nasal cavity expansion before intubation and be carried out to nasopharynx transmucosal and glottis abundant
Surface anesthesia.The method clinically taken at present is to be filled with the padding for being soaked with local anaesthetics and vasoconstrictor to nasal cavity
Then expansion carries out local anaesthetics injection to nasal cavity and oral cavity with spraying gas.This method has shortcoming.
1, it when being expanded with the filler for being soaked with local anaesthetics and vasoconstrictor to nasal cavity, needs different-diameter
The padding for being soaked with local anaesthetics and vasoconstrictor is inserted into nasal cavity in turn from fine to coarse, it is time-consuming and be easy to cause nasal bleeding and
Patient does not accommodate repulsion, is furthermore unable to reach ideal expansion and anaesthetic effect to deep nasal cavity.
2, local anaesthetics injection is carried out to oral cavity with spraying gas, ideal anaesthetic effect is unable to reach to glottis position, especially
It is to the limited patient of mouth opening, to anesthesia difficulty at bottleneck throat and glottis.
Summary of the invention
It is an object of the invention to overcome defect existing in the prior art, provide a kind of nose laryngopharynx surface anesthesia device and
Its operating method.The device not only can carry out abundant surface anesthesia to nose mucosa and glottis, but also can expand to nasal cavity, together
When reduce patient sense of discomfort and rejection.
Its technical solution is as follows:
A kind of nose laryngopharynx surface anesthesia device, the conduit including inner hollow are fixed on outside supravasal expansion capsule and expansion capsule
Enclose to medicine cavity, the conduit is the nontoxic PVC plastic conduit of hard long arc shape, and catheter tip and front end are equipped with fluid hole, institute
It states fluid hole to spray for anaesthetic, be anaesthetized at bottleneck throat and glottis, the other end of conduit is syringe connector, is used for
The injecting anesthetic drug into conduit.Expansion capsule closed end be provided with self-closing gas injection port, expanded after gas injection, for nasal cavity into
Row expansion, the outer wall to medicine cavity be the semi-permeable membrane that can be expanded, and end is provided with self-closing medicine-pouring port, for inject arcotic with
Vessel retraction medical fluid carries out surface anesthesia to nasal cavity and shrinks nasal membrane blood vessel.
Further, the internal diameter of the conduit be 2mm, outer diameter 3mm, length 18cm,.
Further, the expansion capsule is located at away from catheter tip 8cm at conduit mouth.
Further, the fluid hole is located at catheter tip and front end 8cm, and quantity is 10-15, diameter 0.1mm.
Further preferably, the expansion capsule is low appearance high pressure cuff, and cyst wall is transparent plastic film.
Further, the transparent plastic film with a thickness of 0.15mm.
The operating method of nose laryngopharynx surface anesthesia device of the present invention, comprising the following steps: local anaesthesia drug will be housed
Syringe is connected to syringe connector, and marginal not penetrates local anaesthetics, and side via intranasal application is inserted into nasopharyngeal surface anesthesia casing, to nasopharynx larynx
Glottis carries out surface anesthesia, while having lubricating action to nasal cavity.After catheter proximal end arrives at glottis, through self-closing gas injection port to expansion
Capsule slowly injects gas by several times, can expand to nasal cavity, while injecting local anaesthetics and blood to medicine cavity through self-closing medicine-pouring port
Pipe shrinks drug, carries out surface anesthesia to nasal cavity and shrinks nasal membrane blood vessel.
Beneficial effects of the present invention:
The catheter outer diameter that nose laryngopharynx surface anesthesia device of the invention uses for 3mm, design for arc-shaped by tip, and insertion nasal cavity holds
Easily, and small to the damage of patient's nasal cavity, patient is easy-tolerated.Catheter length is 18cm, and tip can reach at glottis, by tip and preceding
Fluid apertures is brought out, to abundant surface anesthesia at bottleneck throat and glottis.The slow gas injection expansion of capsule graded is expanded, nasal cavity is gradually expanded
, patient is easy-tolerated, avoids filling expansion repeatedly and easily causes nasal bleeding.It is semi-transparent for that can be expanded to the outer wall of medicine cavity
Film, drug comes into full contact with nasal membrane after injecting local anaesthetics and vessel retraction medical fluid, enhances drug effectiveness.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of nose laryngopharynx surface anesthesia device of the present invention, in figure: 1, conduit, 2, expansion capsule, 3, be administered
Chamber, 4, semi-permeable membrane, 5, drug delivery port, 6, self-closing medicine-pouring port, 7, syringe connector, 8, self-closing gas injection port.
Specific embodiment
Technical solution of the present invention is described in more detail with reference to the accompanying drawings and detailed description.
Referring to Fig.1, a kind of nose laryngopharynx surface anesthesia device, the conduit 1 including inner hollow are fixed on supravasal expansion
