| 摘要 |
An emergency percutaneous trans-tracheal high flow oxygen resuscitator of the catheter type which restores breathing to a non-breathing patient comprising a soft plastic catheter molded from non-pyrogenic thermoplastic material such as polyethylene, polytetrafluorethylene, polypropylene, polycarbonate or other readily sterilized, orientable material which is precurved at its long tubular bottom portion for proper positioning in the median axis of the trachea after straight insertion by means of a cooperating, interiorly positioned hypodermic needle through the crico-thyroid membrane of the patient. The catheter has outwardly projecting wing portions at the top collar portion, the collar accommodating a suction tube or an oxygen tube after the needle is removed. Suction aids in the exhale phase of ventilating the lungs. |
