Abstract
The utility model discloses combination intubation equipment for difficult airways. The combination intubation equipment comprises a laryngeal mask airway, a connecting tube and a light stick, wherein the laryngeal mask airway comprises a cuff, an inflation bag and a tube, the connecting tube is connected with the tube of the laryngeal mask airway, the light stick is inserted into the tube of the laryngeal mask airway via the connecting tube, and an oxygen inlet is arranged on the connecting tube. When the combination intubation equipment is used, the laryngeal mask airway is placed in the laryngeal of a patient subjected to induction of general anesthesia, and wraps the glottis of the patient, the esophagus of the patient is isolated in an inflation manner, the patient is subjected to continuous oxygen inhalation after the connecting tube is connected with the tube, ventilation of the lung of the patient is determined by end-expiratory CO2 partial pressure or auscultation, then a tracheal tube is sleeved on the outside of the light stick, the light stick penetrates through a one-way valve, is guided by the laryngeal mask airway with a physiological curve, reaches an inlet of the glottis of the patient when an operator sees a bright spot at a cricoid cartilage of the patient, and then the tracheal tube is placed into the glottis of the patient. The combination intubation equipment has the advantages that the success rate of tracheal intubation for patients suffering from difficult airways can be increased, and accordingly life safety of the patients suffering from the difficult airways is guaranteed.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of difficult airway associating catheterization equipment.
Background technology
In clinical, for patient with general anesthesia, adopting tracheal intubation control to breathe, is one of requisite measure of management respiratory tract.But for the difficult airway patient, after general anesthesia is induced, often can't expose glottis, even can't see lower associating, or ignorant of the economics visits when endotracheal tube can't be sent into glottis, the lighter can cause operation to carry out, and severe one can cause anoxia, CO because of serious dysfunction of ventilation
2Accumulate, even cardiac arrest.Therefore, how improving the success rate of difficult airway patient intubate, is one of important means that guarantees patient with general anesthesia breathing, minimizing general anesthesia death.
The utility model content
For improving the success rate of difficult airway patient intubate, the utility model proposes a kind of difficult airway associating catheterization equipment for the difficult airway patient.
For solving the problems of the technologies described above, this utility model adopts following technical scheme:
A kind of difficult airway associating catheterization equipment comprises:
Laryngeal mask, connection tube, endotracheal tube and light cane, described laryngeal mask comprises cuff, gas cell and conduit, connection tube links to each other with the conduit of laryngeal mask, endotracheal tube is enclosed within light cane outside, and endotracheal tube and light cane are inserted in the conduit of laryngeal mask by connection tube, and connection tube is provided with oxygen intake.
Above-mentioned smooth cane comprises light emitting diode, seal wire and battery, and an end of seal wire is provided with light emitting diode, and the other end is equipped with the battery to the light emitting diode power supply.
Above-mentioned smooth cane can be replaced by branchofiberoscope.
Be provided with unidirectional valve in the above-mentioned connection tube, the light cane inserts in the conduit of laryngeal mask by this unidirectional valve.
