Abstract: Apparatus for respiratory therapy, which is particularly useful in a neonatal context, and related methods, the apparatus comprising an adaptor for connection to the exposed fitting of an indwelling endotracheal tube of any one of several types to an aspirating apparatus which may include ventilating capacity. The adaptor includes an appendage by which a lavage solution can be selectively introduced into the lungs of a patient through the indwelling endotracheal tube to loosen secretions without necessarily interrupting the ventilation cycle or requiring that the ventilating circuit be broken. The apparatus also comprises a fitting at one end of an aspirating/ventilating apparatus which has low dead space, alleviating the incidence of inadvertent disconnection and trauma induced by unintended displacement of the end fitting and accommodating not only aspiration and ventilation but also monitoring of certain vital indicators to allow prompt medical response to contraindications.
Abstract: A novel hyperbaric oxygenation apparatus, and related methods, the apparatus comprising a chamber in the form of a disposable inflatable bag of impervious inexpensive synthetic resinous material which can be used at any desired location, such as a hospital, a home or other site where oxygen can be appropriately made available. The pressure of the oxygen in the collapsible bag is pulsated between maximum and minimum positive values. The patient cyclically experiences first a medicinal increase in the blood gas levels in the limb under treatment with a corresponding restricted blood flow and, thereafter, a progressive return to normal blood flow rates in the limb of the patient as the pressure in the chamber changes from maximum to minimum positive pressure. A respirator, normally used for intubated respiratory patients, in conjunction with a single oxygen influent/effluent port in hyperbaric oxygenation apparatus is efficacious to provide the oxygen and generate the desired pressure variations.
Abstract: A percussor for respiratory percussion therapy, comprising a lightweight flexible cantilever handle and a soft elastomeric percussion cup secured to the distal end of the handle. The bell-shape of the percussion cup provides a highly effective percussion shock wave and sound, while accommodating a wide range of striking forces and angles relative to any desired body surface. A lip having a large surface area substantially avoids irritation, trauma and injury to the patient.
Abstract: A ventilating and aspirating assembly comprising an aspirating catheter tube internally disposed within and coextensive with a surrounding flexible collapsible sterility preserving film envelope, a connector by which ventilating air is involuntarily delivered to and exhausted from the lungs of a medical patient, said connector comprising structure which accommodates the manual insertion of the catheter tube into and manual removal from the trachea/bronchi patient through the connector. This facilitates aspiration of undesired respiratory fluids.
Abstract: The foam dispensing device is intended for use in the inverted position and includes a container having a reservoir portion for holding a foamable liquid and a bellows portion for holding air. A foam producing unit is mounted in the discharge port, the foam producing unit including a housing mounted in and receiving air from the bellows and a liquid receiving conduit extending from the foam producing unit into the reservoir. A separate air return conduit communicating with atmosphere extends into the container air. The container reservoir and bellows portions are separated by a finger-engageable waist portion to facilitate operation of the bellows portion.

Abstract: A blood-gas sampler in the nature of a syringe comprising a hollow internally stepped cylindrical barrel and a coaxial stepped plunger having one or more nesting stepped seals at the leading end thereof, the assembly accommodating arterial blood aspiration causing retraction of the plunger within the barrel and discharge of blood from the hollow of the barrel caused by advancement of the plunger. A clip prevents inadvertent excessive retraction of the plunger during the blood aspiration and blood discharge phases.
