  • Patent number: 6494203
    Abstract: Apparatus and methods are disclosed by which a closed ventilating system accommodates multiple access to the respiratory system of an intubated medical patient without compromising the closed character of the system. Access to the respiratory system through one or more access sites of the closed system apparatus is provided at proximal adapter ports to ventilate the lungs of the patient with gas or gases, to aspirate secretions from the lungs, to oxygenate the lungs to eliminate or reduce residual co2 therefrom, to visually inspect selected parts of the respiratory system, to sample sputum and gases, to sense parameters such as flow rates, pressure, and temperature, to flush with washing solution, and/or to administer medication, gases, and/or lavage. A distal swivel fitting provides multiple sealing sites by which entry of atmosphere is prevented.

  • Patent number: 5735271
    Abstract: Apparatus and methods are disclosed by which a closed ventilating system accommodates multiple access to the respiratory system of an intubated medical patient. Access to the respiratory system is accomplished via one or more access ports through an attached accessory device in order to ventilate the lungs of the patent with gas or gasses, aspirate secretions from the lungs, oxygenate the lungs, visually inspect selected parts of the respiratory system, sample sputum and gasses, sense parameters such as flow rates, pressure, and temperature, flush the respiratory tract with washing solution, and/or administer medication, gasses, and/or lavage. The embodiments of the present invention may have such accessory devices permanently fixed to the adaptor or may be removable and replaceable. Access control means may be provided whereby one or more access ports are selectively aligned with the adaptor in order to allow passage of an attached accessory device therethrough.

  • Patent number: 4640440
    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.

  • Patent number: 4269186
    Abstract: An intravenous needle assembly and an associated manufacturing method, wherein the needle assembly comprises a hypodermic needle attached to a hub at its trailing end, a transparent blood detection chamber integral with the hub, a catheter disposed around the needle and the needle hub and a plug closing the blood detection chamber, the plug having air breathing capacity so that upon venipuncture blood from a vein may flow through the needle into the blood detection chamber without substantial air resistance to such flow to visually confirm the accuracy of the introduction of the needle into a vein. The plug is centrally hollow and has an axially directed leading projection connected to an annular shoulder or flange. The projection comprises a symmetrical hollow truncated conical extension with a hollow interior and walls having pairs of longitudinally directed ribs insuring ready passage of air from the flashback chamber along the outside of the projection under pressure of the heart.

The plug is centrally hollow and has an axially directed leading breather projection connected to an annular shoulder or flange. The breather projection comprises a symmetrical hollow truncated conical extension with a hollow interior and walls having a plurality of narrow slits permitting ready passage of air under pressure of the heart while substantially preventing the passage of blood through the slits.
