Abstract: An airway intubation device having a one-piece molded body of biocompatible material with an ergonomically designed hand piece for left hand manipulation. The body includes a cap piece and linear-curved-linear insertion piece having a channel in one side thereof for insertion of an endotracheal tube. The channel has a wide entry portal disposed ahead of the hand piece so that a clinician may load the channel with a tube while the insertion piece is in the mouth of the patient without having to view the entry portal. The device may include a viewing system with a camera so that a clinician can view the insertion of the tube between the vocal cords of a patient without contact.

Abstract: A visualization instrument comprising a display support component removably coupled to a component insertable into a target space. The insertable component includes a camera providing images of the target space. The images are presented in a display device supported by the display support component. The insertable component may be discarded after a permitted number of uses.

Abstract: A laryngeal tube comprising a tubular component and a nozzle having a central cavity, an anterior opening and a tongue at least partially covering the central cavity. In one example, the laryngeal tube has a first lumen to deliver gases to a patient and a fluid barrier supported by the nozzle. In other examples, the laryngeal tube may include additional lumens including a service lumen to perform a function associated with the thorax and an inflation lumen to inflate the fluid barrier.

Abstract: A visualization instrument comprising a camera including an optical train and an image sensor. The optical train includes at least one lens and may include a prism. Optical images received by the optical train are captured by the image sensor, which may be positioned adjacent the image sensor to reduce the profile of the camera.

Abstract: A strap system is useable with an anesthesia/respiratory face mask having an axially extending gas port connector and a gasket member. The gas port connector has a first diameter, and the gasket member is engageable with and conformable to a face of a patient. The strap system includes a strap member having a first end portion, a second end portion and a middle portion, and a collar. The collar includes an axially extending portion having a second diameter. The strap system includes a strap having a first end portion, and a second end portion; the collar also includes a radially extending portion having at least a first and a second slot through which the first and second end portions, respectively of the strap can pass. The slots are sized for adjustably receiving and fixedly positioning the first and second end portions of the strap.

Abstract: An anesthesia delivery device can be coupled to a ventilation system. The device includes an inspiratory gas line having a machine end and a patient end. The machine end can be fluidly coupled to the ventilation system, and the patient end can be received within the naris of the patient. A face mask having a dome portion can cover the patient's nose without covering the patient's mouth and defines an inside air space between the patient's nose and the dome portion, and an outside air space exterior of the dome portion. A vent allows gas to pass between the inside and outside air spaces. An exhaust port can be fluidly coupled to the exhaust gas output. The exhaust port and vent can cooperatively exert a negative pressure on the outside air space for preventing inspiratory gas from entering the outside air space.

Abstract: A non-tracheal ventilation tube includes a multi-lumen tube shaft having a proximal end and a distal end, a proximal cuff and a distal cuff. The multi-lumen tube shaft is separated into a ventilation channel extending from a proximal ventilation opening to a distal ventilation opening, a suction channel extending from a proximal suction opening to a distal suction opening, and an inflation channel. The proximal cuff is attached to the tube shaft and is connected to the inflation channel for inflation and deflation. The distal cuff is attached to the tube shaft on the distal side of the proximal cuff and is connected to the inflation channel for inflation and deflation. The proximal suction opening and the proximal ventilation opening are located on the proximal side of the proximal cuff. The distal suction opening is located on the distal side of the distal cuff. The distal ventilation opening is located between the proximal cuff and the distal cuff.

Abstract: A unilimb breathing circuit has a proximal end coupling member, a distal end coupling member, an expiratory tube extending between the proximal and distal end coupling members, and an inspiratory tube extending between the proximal and distal end coupling members. The expiratory tube is a corrugated expiratory tube that is expandable between a fully compressed rest position, and a fully expanded rest position, and has a plurality of intermediate rest positions. At the plurality of intermediate rest positions, the expiratory tube is capable of maintaining its rest length without the exertion of an external force. The inspiratory tube is a corrugated inspiratory tube having a length that is variable between a fully compressed rest position and a fully expanded rest position, and includes a plurality of intermediate rest positions between the fully expanded rest position and the fully compressed rest position.

Abstract: A sleeved filter apparatus prevents germs from becoming resident on both the interior and exterior of a breathing device. The sleeved filter apparatus includes a filter member and a sleeve member. The filter member is composed of a first and second enclosure half which are sealed on their interior ends. The external ends of the two enclosure halves have connectors for connecting the sleeved filter apparatus to a breathing device and/or a patient airway component. A filter element is disposed inside the filter member enclosure for preventing gases from flowing between the first connector and the second connector of the filter member without passing through the filter element. This filter member prevents germs from passing between the patient and the interior of the breathing device. The sleeve member is made of a flexible material, and has a first open end, a second open end, and a middle portion extending between the first open end and the second open end.

Abstract: A breathing circuit is provided for conveying an inspiratory gas from a gas dispensing apparatus to a patient, and for conveying an expiratory gas from the patient. The circuit includes a corrugated expiratory tube having a first end and a second end. The expiratory tube has a relaxed length. A corrugated inspiratory tube is provided which is disposed generally colinearly and interiorly of the expiratory tube. The inspiratory tube has a first end disposed adjacent to the first end of the expiratory tube, a second end disposed adjacent to the second end of the expiratory tube, and a relaxed length greater than the relaxed length of the expiratory tube such that the inspiratory tube normally exerts a longitudinally directed pressure on the circuit. A first end coupling member is fixedly coupled to both the inspiratory tube and the expiratory tube. The first end coupling member is generally transparent and hollow, and has an interior and an exterior.
