Description
Technical field
The present invention relates to a kind of disposable video laryngoscope piece with trachea cannula guiding groove and air flue surface anesthesia guiding groove
And its application method, suitable for medical instruments field.
Background technology
Video laryngoscope is advantageous to the exposure of higher glottis due to the radian and front end larger angle of its laryngoscope blade.Disposably
Laryngoscope blade is avoided that cross-infection.Therefore, the video laryngoscope equipped with disposable laryngoscope blade is put into practice in current clinical anesthesia
In, it is widely used in the trachea cannula of general anesthesia.However, the in the market of medical material is had no with trachea cannula guiding at present
The disposable video laryngoscope blade of groove, the video laryngoscope with disposable laryngoscope blade be by tube core by tracheal catheter it is moulding into
Fish hook shape completes trachea cannula.Because the radian of its eyeglass, oropharynx cavity space appear very when video laryngoscope exposes glottis
Limited, during trachea cannula, when the tracheal catheter that leading portion is bent to 80 degree enters pharyngeal by oral cavity, conduit leading portion particularly covers
Capsule part is easily polluted by intraoral secretion, and contaminated conduit is placed to tracheal strips, due to being oppressed after sleeve bag gas-filling
Tracheal mucosa causes local mucous membrane ischemic, it is resisted the ability of bacteria planting and declines, ultimately increases tracheae and lung inflammation
Incidence.In addition, in clinical anesthesia practice process, after the tube core moulding for tracheal catheter is not sterilization, make
The risk that trachea cannula also increases germ contamination on the inside of tracheal catheter is carried out with this kind of tube core.Therefore, clinically commonly use at present
Disposable video laryngoscope blade may can reduce the cross-infection of pars oralis pharyngis between patient, but patient's trachea may be increased
The interior and risk of pulmonary infection.Therefore, clinically need to be improved the structure of currently used disposable video eyeglass,
On the premise of not influenceing trachea cannula operation, reduce and even avoid tracheal catheter from being contaminated caused ALRI.
Need firmly above to carry laryngeal tissue and muscle when common laryngoscope appears glottis makes local organization by very big work more
Firmly, video laryngoscope makes its upper lifting force be only common laryngoscope 1/10~1/5 due to the radian of its laryngoscope blade, so as to mitigate to tongue
Root and bottleneck throat stimulate, and make the haemodynamics of patient more stable, while reduce postoperative sore-throat and throat mucosa hemorrhage
Occur, such case is more obvious in the patient of conscious intubation.Under video laryngoscope auxiliary, mouth and throat is carried out using laryngotracheal topical anesthesia kit
Surface anesthesia, the pass through operation of orotracheal tube of Conscious Patients is set to become simple and easy.Because laryngotracheal topical anesthesia kit is thinner, need not during operation
Disconnected adjustment angle of bend and direction, or even the local anaesthetics syringe for needing assistant's help to buttress laryngotracheal topical anesthesia kit afterbody, to assist to fix larynx
The direction of numb pipe front end carries out local anaesthetics sprinkling.Simultaneously there is also with tracheal catheter analogue, if laryngotracheal topical anesthesia kit front end is easily by mouth
The danger of pharyngeal secretion pollution.For this reason, it may be necessary to the structure of the disposable video eyeglass to clinically commonly using at present is improved.
The content of the invention
It is an object of the invention to provide a kind of disposable with trachea cannula guiding groove and air flue surface anesthesia guiding groove
Video laryngoscope piece and its application method, it is dirty by oropharynx secretions that tracheal catheter can be not only reduced when carrying out trachea cannula
Dye, and laryngotracheal topical anesthesia kit can be easy to carry out accurate pars oralis pharyngis surface anesthesia, while make operation before oral clear-headed trachea cannula
It is simpler easy.
