Abstract: A tracheotome for the automatic mechanical performance of an emergency tracheostomy. An incision into the trachea is made upon release of a power-operated cannula with a cutting blade by a triggering mechanism. The device consists of a powered, hollow cannula with a cutting blade on the frontal edge retained in a hollow, elongated housing. A triggering mechanism releases the cannula to forcefully extend from the housing. The tracheotome is placed adjacent to the throat at an angle and the triggering mechanism is activated. The cutting blade penetrates the tissue and trachea allowing entry of the cannula into the trachea. The cannula and housing provide an immediate temporary channel for air into the trachea and permit a breathing tube to be inserted through them into the trachea. The cannula has a curved portion in its leading edge to direct the insertion of the breathing tube in a downward direction into the trachea to prevent damage to the posterior wall of the trachea.

Abstract: An animal inhalation apparatus includes a mask which is directly fastened to a vaporizer. The baglike mask has a portion of its surface disposed in the mouth of a horse and is secured by a tightening belt so that the horse is prevented from opening its mouth and is forced to breath through its nostrils, which lie inside of the bag. The vaporizer operates in the rhythm of the breathing process. The horse is not connected to the vaporizer through a cumbersome hose, and only the respiratory organs are in contact with the inhalation medium.

Abstract: A toroid shaped mouthpiece that is inserted into a patient's mouth between the patient's gums and cheeks. The mouthpiece is particularly configured to sustain an oral space through which the patient can breathe from an anesthesia face mask. With the anesthesia face mask in place over the patient's nose and mouth cavities, the mask generates a good seal with the patient's cheeks because the mouthpiece insures that the cheeks will remain flushed out against the mask. This is particularly advantageous in the case of edentulous patients.

Air is supplied to the trainee through a plurality of regulators and valves via an air passage opened by a mechanical actuation linkage, which simulates the actual actuation device and technique.

Abstract: Oxygenation within the brain of a child being born is monitored by light, initially transmitted by a bundle of fiber optics in one channel of a catheter held to the baby's scalp by mild suction, the condition of the brain being monitored via reflected light from the brain transmitted through a light fiber optic bundle in a second channel of the catheter.

Abstract: An apparatus for delivering oxygen to a patient is preferably constructed so as to include an elongted, deformable receptacle having an open side extending along its length, a flexible, "floppy" diaphragm secured at its edge so as to seal off or enclose the open side of the receptacle and a retainer for protecting and for limiting expansion of the diaphragm located along the side of the diaphragm remote from the receptacle. As the apparatus is used, oxygen is constantly delivered to the extremities of the receptacle through appropriate supply lines. On exhalation exhaled gas is forced by the pressure of the breath through a cannula--preferably a nasal cannula--into the interior of the receptacle remote from the supply lines. This cannula is used so that gas can flow. This exhaled gas is used to force the diaphragm against the retainer, opening up the interior of the receptacle in an amount such that some of the exhaled gas will be held in the receptacle.

Abstract: A respirator device particularly for use in association with a tube insertable into a person's trachea comprises a trachea tube having an inflatable cuff which seals the tube with the person's trachea. A line for ventilating gas extends into the tube and terminates in a jet nozzle directed to the trachea. The opposite end of the tube is provided with a connection to atmosphere which also makes it possible to provide a controlled vacuum pressure at this end particularly in the expiration phase. Control is effected between the ventilating gas and the vacuum for regulating the respiration. With the inventive method the vacuum is provided at the outer end of the trachea tube particularly during respiration and it is effected by directing a vacuum pressure gas supply connection through a Venturi connection to the tube which produces the vacuum in the tube and communicates the tube to atmosphere. This gas connection is controlled along with a ventilating pressure gas connection to provide the desired respiration.
