Description

A kind of novel difficult airway Intubaction device

Technical field

This utility model relates to a kind of medical apparatus and instruments, refers in particular to a kind of novel difficult airway Intubaction device.

Background technology

Surgical patient and the critical illness difficult airway that gives emergency treatment to a patient not is that rare (so-called difficult airway is meant and may causes the various clinical settings of difficulty to safeguarding airway patency and tracheal intubation after anaesthetizing.Difficult airway is not rare in the anesthesia patient clinically, as deal with improperly, the lighter anaesthetizes failure, operation extension, air flue damage etc., weight person can be because of serious dysfunction of ventilation anoxia, even death by suffocation), as in oral and maxillofacial surgery and the orthopaedic patients, the incidence rate of difficult airway is higher in some cases.If deal with improperly, the lighter anaesthetizes failure, operation extension, air flue damage etc., and weight person can cause cardiac arrest, brain damage even death because of serious dysfunction of ventilation anoxia.Discovering of the relevant death of anesthesia, 70% anesthetic death case are that main cause is respiratory tract obstruction, difficult intubation and intubate enter the esophagus by mistake because of due to the respiratory problems.

Be the airway intubation problem of overcoming a difficulty, Chinese scholars is endeavoured research and has been invented a lot of new techniques and new method, comprise branchofiberoscope (fiberoptic bronchoscope, FOB), McCoy laryngoscope, laryngeal mask airway (laryngeal mask airway, LMA) etc.The development of these apparatuses and technology has improved the success rate of difficult tracheal intubation greatly.Enter after nineteen fifties, a kind of new light guide cannula technology occurred, ultimate principle is to utilize the brightness of light source perspective to judge that intubate optical wand (Lightwand) is whether in trachea.But early stage light guide cannula technology simple coarse, clinical practice is not high.After going through several generations innovation and development, Trachlight difficult airway Intubaction device comes out and is able to extensive use clinically in the U.S. in recent years.

Trachlight by handle, optical wand, lead core and form.The operator hands handle, with endotracheal tube be enclosed within can be luminous optical wand on, insert patient throat, with light point as the guiding, adjust the position, light just shows that optical wand enters trachea if throat positive medium ring first film place sees clearly, with conduit being sent in the trachea.

Compare with tracheal intubation under the traditional direct laryngoscope, Trachlight has the stimulation of larynx less, can not cause the advantage of tangible hemodynamics disorder.For oral and maxillofacial surgery and the inconvenient patient of orthopaedic patients mouth opening, as long as allowing, the space inserts conduit, can finish tracheal intubation, also can greatly reduce per nasal blind tracheal intubation mortality through nasal intubation under the light guiding; For severe trauma patient mouth, nose, the courageous and upright secretions patient of pharyngeal cavity, because the Trachlight intubate does not need photopic vision, can directly use Trachlight to carry out intubate, save rescue time; For SARS and other respiratory infectious disease patient, the intubationist can utilize the Trachlight remote-controlled operation, reduces medical personnel's infection rate; Carry out tracheal intubation for limited patient of neck movement such as fracture of cervical vertebra patient,, can avoid intubate complication such as paraplegia etc. because the Trachlight intubate need not moved patient's head position; In addition, Trachlight is small and exquisite because of its instrument, is easy to carry about with one, and intubate is convenient and swift, is beneficial to pre hospital care and field operations especially and rescues.

Compare with branchofiberoscope, Trachlight for can't use branchofiberoscope (as on the emergency tender or in the emergency room) or when bronchoscope is difficult to operate (in as air flue the more or patient's head of blood or secretions can not be anteflexion or after when stretching) be particularly useful, and operating technology is easy to learn, and Intubaction device is cheap.

Yet the Trachlight intubation technique is by American scholar research invention, and its design and use all have west crowd's anatomy and ergonomic features.When using the Trachlight intubate, general earlier with optical wand at fixing crooked 90 ° of one-tenth one cranks in scale place, be the J type.The length of J type galianconism and curvature have adopted a large amount of west crowds to go up the air flue anatomical data in this design, and can this design be applicable to that compatriots remain query.It is low that we find that in clinical position successful intubation is reported as more abroad, and the probability that conduit is strayed into esophagus also is reported as height more abroad.

Secondly, the Trachlight intubation technique is the blind tracheal intubation instrument, mainly relies on the position of light and power to judge catheter positioning, in the clinical practice sometimes optical wand enter in the esophagus and can not differentiate, cause erroneous judgement; For obesity patient and the relatively poor patient of cervical region transmittance, because transmittance is relatively poor, optical wand enters air flue and also can judge by accident to entering esophagus sometimes.For this reason, we design a small-sized carbon dioxide sensor module at imagination at the handle place, combine by integrated circuit and Trachlight, carbon dioxide numerical value in quick, the quantitative or semiquantitative mensuration tube chamber, thus can effectively judge tracheal catheter position rapidly.
