Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
158 words
A method of placing respiratory medication into the lung/airway system of a medical patient comprising the steps of: interposing ventilating/aspirating apparatus between the lung/airway system of a patient and a ventilator; causing the ventilator and the ventilating apparatus to involuntarily cycle influent ventilating gas to the lungs of the patient and to remove effluent gas from the patient through a tracheal tube; selectively introducing an aspirating catheter into the respiratory system to remove secretions from the lungs of the patient without disconnection of the ventilating apparatus; selectively introducing at any time a selected quantity of respiratory medication across a selectively actuated one-way valve and along a central passage of a pressurized hand-held container into the ventilating apparatus through a centrally unobstructed passageway of a fitting in which the valve of the container is actuated immediately adjacent the tracheal tube of a patient without disconnection of the ventilating apparatus or interruption of either the aforesaid ventilating or aspirating steps.
Claim 2
Independent Claim
158 words
A method of placing respiratory medication into the lung/airway system of a medical patient comprising the steps of: interposing ventilating/aspirating apparatus between the lung/airway system of a patient and a ventilator; causing the ventilator and the ventilating apparatus to involuntarily cycle influent ventilating gas to the lungs of the patient and to remove effluent gas from the patient through a tracheal tube; selectively introducing an aspirating catheter into the respiratory system to remove secretions from the lungs of the patient without disconnection of the ventilating apparatus; selectively introducing at any time a selected quantity of respiratory medication across a selectively actuated one-way valve and along a central passage of a pressurized hand-held container into the ventilating apparatus through a centrally unobstructed passageway of a fitting in which the valve of the container is actuated immediately adjacent the tracheal tube of a patient without disconnection of the ventilating apparatus or interruption of either the aforesaid ventilating or aspirating steps.
Claim 3
Dependent Claim
27 words
A method according to claim 1 wherein the selective introducing step comprises introducing the medication as an atomized spray through the centrally unobstructed passageway of said fitting.
Claim 4
Dependent Claim
27 words
A method according to claim 1 wherein the selective introducing of respiratory medication step comprises introducing the medication through selectively openable medication port structure in said fitting.
Claim 5
Dependent Claim
39 words
A method according to claim 1 wherein the introducing of medication step is preceded by the step of externally opening a normally closed end of the centrally unobstructed passageway and is followed by closing of the normally closed end.
Claim 6
Independent Claim
75 words
A method of introducing medication into the lungs of a medical patient comprising the steps of: subjecting the patient to cycles of involuntary influent and effluent gaseous respiration; subjecting the patient to cycles of involuntary aspiration of secretions from the lungs without incapacitating said respiration capability; introducing medication in spray form from a pressurized container comprising a manually activated self contained, normally closed valve during said respiration cycle or between the respiration and aspirating cycles.
Claim 7
Independent Claim
75 words
A method of introducing medication into the lungs of a medical patient comprising the steps of: subjecting the patient to cycles of involuntary influent and effluent gaseous respiration; subjecting the patient to cycles of involuntary aspiration of secretions from the lungs without incapacitating said respiration capability; introducing medication in spray form from a pressurized container comprising a manually activated self contained, normally closed valve during said respiration cycle or between the respiration and aspirating cycles.
Claim 8
Dependent Claim
106 words
A ventilating/aspirating apparatus comprising: a hollow ventilating circuit comprising an at-patient hollow ventilating and aspirating fitting adapted to be interposed between a respirator and the lung/airway system of a patient; an aspirating catheter tube reciprocably displaceable through said at-patient fitting; said fitting comprising medication influent structure; the medication influent structure comprising closure means which can selectively be manually opened and closed and influent passageway means and orifice means, comprising means for receiving insertion and means for stopping further insertion of a stem of a pressurized-medication-containing container comprising a manually activated, self-contained, normally closed valve, where the influent passageway means merge with the hollow of the fitting.
Claim 9
