Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
150 words
A pulmonary valve apparatus for providing medication to a patient including a generally tubular body providing a flow path from a source of medication to a patient, said tubular body having a first end adapted to be coupled to various forms of medication and a second end adapted to be coupled to a patient for receiving said medication, a slide means disposed within a slide path in said tubular body for selectively closing and opening said flow path through said tubular body, and sealing means disposed between said slide means and said slide path for insuring a tight seal between said slide means and said slide path; a valve coupled to said rear portion of said tubular body, a source of suction and a source of oxygen coupled to said valve, said valve being operable to connect either suction or oxygen to said tubular body and thus to a patient.
Claim 2
Dependent Claim
150 words
A pulmonary valve apparatus for providing medication to a patient including a generally tubular body providing a flow path from a source of medication to a patient, said tubular body having a first end adapted to be coupled to various forms of medication and a second end adapted to be coupled to a patient for receiving said medication, a slide means disposed within a slide path in said tubular body for selectively closing and opening said flow path through said tubular body, and sealing means disposed between said slide means and said slide path for insuring a tight seal between said slide means and said slide path; a valve coupled to said rear portion of said tubular body, a source of suction and a source of oxygen coupled to said valve, said valve being operable to connect either suction or oxygen to said tubular body and thus to a patient.
