Abstract:

A double lumen tube adaptor and valve control system for lung anesthesia includes a housing having a pair of outlet ports with a pair of inlet ports aligned with the outlet ports and a common central inlet port communicating with a central passageway that is controllable by two separate valves for selectively communicating the common inlet port with both outlet ports, one outlet port for communicating the in line outlet and inlet ports.

International Classification:

A61M 500

US Classification:

600 4

Abstract:

The automatic injection device comprises two syringes, one for injecting a measured quantity of radionuclide and a second for injecting a saline solution for flushing the intravenous tubing through which the radionuclide has been delivered. Each of these syringes is driven by a motor which compresses the plunger of the syringe causing it to inject its contents. The motors receive an activation signal from a computer controller which initiates the injection sequence upon receipt of a trigger signal which is provided either by a separate seizure detection computer, by activation by the patient who recognizes an aura indicative of an imminent seizure, or by activation by medical personnel observing the patient. The computer implements a delay cycle to permit verification of the trigger to avoid initiating the injection sequence in the event of false alarms. Since the radionuclide is placed in the syringe in advance of the actual injection, decay of the radioactive element is compensated for by storing more radionuclide in the syringe than is needed, then calculating the quantity of radionuclide to be injected based upon the time delay from the filling of the syringe to the occurrence of the seizure and the half life of the radionuclide.

Abstract:

An emergency airway tube for use in resuscitation of non-breathing patients by inserting the tube through the mouth until it randomly lodges either in the trachea or the esophagus. Only one insertion is needed. The tube is designed to ventilate the lungs regardless of which passageway it is lodged in. The tube has three tubes--the outer tube, an inner tube, which runs along and within the bore of the outer tube, and an air passageway for inflating an inflatable cuff located at the distal end of the outer tube which enters the trachea or esophagus. The end of the inner tube has a pneumatic seal for forming an airtight fit within and adjacent the distal end of the outer tube. The outer tube has a cluster of side air ports in its wall located generally midway between the ends of the tube. If the tip of the tube engages the trachea on insertion, the cuff is inflated and the inner tube will be the air passageway to ventilate the patient. If the tip of the tube engages the esophagus, the cuff will seal off the stomach.
