Adapter for localized treatment through a tracheal tube and method for use thereof

By interposing an adapter between the endotracheal or tracheal tube inserted to a patient and the ventilation and suction systems that are connected to the endotracheal tube, a catheter could be inserted via an input port built into the adapter so as to enable a medical personnel to provide localized treatments in the lungs of a patient without having to disconnect either one of the systems connected to the endotracheal tube. The adapter is configured to have a securing mechanism that allows the medical personnel to secure the medication catheter in place. A one way valve fitted to the apertured arm that forms the input port of the adapter prevents any back flow of fluid from the input port. The catheter is manufactured with calibration markings, most likely equally spaced, and a radiopaque line along its length to enhance the maneuvering and the positioning thereof in the patient so that the distal tip of the catheter could be accurately positioned to the desired location of the patient's tracheal / bronchial tree. As a result, the localized treatment such as the injection of a medicament is accurately provided to the appropriate location where the need is the greatest.

Safe intravenous infusion port injectors

We describe connectors for safely and conveniently injecting measured doses of sterile liquid medications into a patient via one or more infusion ports in intravenous access assemblies. Each connector comprises a tubular injector divided by a rigid septum which holds a hollow needle sharp on each end safely recessed in a leading and in a trailing chamber. The leading chamber snugly holds the trailing limb and penetrable cap of an inserted standard infusion port. The trailing recess snugly holds the leading end of a cartridge with a leading penetrable diaphragm, a bore containing liquid medication, a cartridge piston and trailing bore suitable for insertion of a separate cartridge plunger having markers for measuring doses delivered; or, alternatively, the pentrable cap and trailing limb of second similar infusion port attached by trailing tubing to a large measured volume infusion source. When assembled such that the trailing cap of infusion port is penetrated by the needle in the leading chamber and the leading diaphragm of the cartridge or, alternatively, the leading penetrable cap on a second infusion port is penetrated by the needle in the trailing chamber, such that flow can proceed through the needle, precisely measured doses of sterile liquid medication can be injected into the venous access assembly without possibilities for the user to touch, get stuck or finger-contaminate the needle or its contents. Unique features added to increase the efficiency of the system are a biased leading end on the tubular injector to conveniently and securely accommodate a Y-infusion port; an eccentric needle in the connector, such that rotation prevents the leading sharp end of the needle from passing through the infusion port cap via the same track; and an easily removed biased cap for keeping the cartridge diaphragm sterile.

Compact non-electric medicament infuser

An assembly is provided which includes an infusion device coupled to a standard medication syringe. The medication syringe may be coupled to a stopcock valve having multiple ports and to which syringes, vial adapters, infusion tubing, and multiple other items may be coupled. The infusion device includes a source of power based on a resistance force such as vacuum, spring or gas power. The infusion device converts the resistance based force to usable work in the form of a force applicator. The force applicator includes a driver section on one section of a reciprocating arm and an attachment to the power source on another section of the arm. The driver is pulled outward (excursion) to increase the size of the chamber, creating a force that tends to return the driver back inward, causing incursion. The driver can be attached removably to the syringe plunger to induce the infusion process.
