Description

Visual laryngeal mask trachea cannula with anti-bite function

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to a visual laryngeal mask trachea cannula with prevent stinging disconnected function.

Background

The disposable laryngeal mask trachea cannula in the market at present mainly comprises a main ventilation pipe, a cuff, an inflation line, a check valve and a 15mm connector. The use range is for medical personnel to use when the patient is anaesthetized in the operating room or emergency department, ICU ward to patient and carries out emergency resuscitation, and its effect is mainly anaesthetize operation, artificial ventilation and help patient's breathing establish short-term artificial airway. The functional performance of this laryngeal mask trachea cannula needs bronchofiberscope or visual laryngoscope cooperation to carry out the intubate in the use, and not only operating means is comparatively loaded down with trivial details in clinician's use, and need operate according to equipment precision and clinical experience.

The existing laryngeal mask trachea cannula adopts a separated type, namely, a main ventilation pipe and an inflation pipe are separated in structure and are bonded and combined through glue, so that the function of inflating a cuff in an anesthesia operation is met. Because the laryngeal mask trachea cannula needs to contact the oral cavity and the airway of a patient in the process of surgical ventilation, when the split laryngeal mask trachea cannula is used, the position of the inflation tube can be randomly placed, the inflation tube is easy to tie off, and the patient bites the inflation tube by teeth to cause air leakage, so that the life of the patient is threatened.

Because current laryngeal mask trachea cannula need monitor patient's larynx and air flue when carrying out the process of intubate operation, satisfies the accuracy of intubate location, and this is accurate visual device that just needs to arrange in pairs, and traditional laryngeal mask trachea cannula cooperates bronchofiberscope or laryngoscope to carry out the intubate more, and the equipment operation is got up more loaded down with trivial details and because not be as an organic whole with the body, still need be restricted to clinical experience.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that the prior art is not enough to be overcome and a visual laryngeal mask trachea cannula with prevent biting off function, and can reduce patient's operation risk is provided.

Solve the technical problem, the utility model discloses take following technical scheme:

the utility model provides a visual laryngeal mask trachea cannula with prevent stinging disconnected function, is including ventilating the person in charge, and the one end of ventilating the person in charge bonds and has the cover back of the body, and the surface mounting that covers the back of the body has the cuff, and the both ends intercommunication of ventilating the person in charge is equipped with the inner chamber, and the inner chamber is by ventilating the integrative injection moulding of person in charge, and one side that the cuff is close to the person in charge of ventilating is equipped with the gas pocket, and it has the gas tube to bond in the gas pocket, and the gas tube runs through the inner chamber, the one end that the gas pocket was kept away from to the gas tube is installed and is instructed the gasbag, indicates that the bonding has the check valve in the gasbag, is equipped with in the person in charge of ventilating and ventilates chamber and drainage chamber, bonds in the cuff.

The utility model discloses one side that the cover back of the body was kept away from in the chamber of ventilating is installed and is connected.

The utility model discloses it has the spring to bond just to be located between joint and the cover back of the body in the ventilation chamber.
