  • Patent number: 10500391
    Abstract: An adapter (100) has a through hole (103). A first end portion (101) of the adapter includes a tubular portion (110) on which a first projection (111) and a second projection (112) are provided. The adapter can be connected to a male connector at a first position where a claw (32) of the male connector is engaged with the first projection (111) and at a second position where the claw (32) is engaged with the second projection (112). When the adapter is connected at the first position, a flow channel (11) of a male member (10) is sealed with a cover (4). When the adapter is connected at the second position, the adapter compressively deforms an outer circumferential wall (45) of the cover so that the flow channel of the male member is in communication with the through hole (103) of the adapter.

    Abstract: Methods and systems for determining the concentration of one or more analytes from a sample such as blood or plasma are described. The systems described herein can be configured to withdraw a sample from a source of fluid, direct a first portion of the withdrawn sample to an analyte monitoring system and return a second portion of the sample. The analyte monitoring system can be connected to the fluid source via a connector that is configured to improve fluid flow and reduce blood clotting risk. These goals can be accomplished, for example, by employing coatings in or on a connector, positioning a resilient substance at or near the junction, by reducing dead space volume, by using resiliency to improve fit, by extending a portion of one connector to better mate with a portion of another connector, etc.

  • Patent number: 8511309
    Abstract: A coupling for connecting a ventilator tube to a tracheotomy tube has a latching mechanism which prevents the coupling from axially displacing a tapered tubular extension of the tracheotomy tube after they have been mated in a pneumatically discrete path. For use with known adult tracheotomy tubes which have inner and outer cannulas, the latching mechanism engages the coupling with the leading end of the outer cannula collar with the inner cannula collar sandwiched therebetween. For use with known one piece children's tracheotomy tubes, the latching mechanism is a clamshell contoured to concentrically grip the tapered tubular extension of the tracheotomy tube. Interlocking the coupling and the tracheotomy tube prevents them from inadvertently axially displacing from each other. Non-axial force disengages the coupling from the tracheotomy tube so that the coupling can be axially displaced without exertion of excessive axial force on the system and the patient.

  • Patent number: 7921846
    Abstract: A heat and moisture exchanger for both conducting a stream of air produced by a ventilator to a moisturizing medium and internally bypassing the moisturizing medium if aerosolized medication is introduced into the stream includes a housing having a ventilator-side port coupled to an outlet of a ventilator and a source of aerosolized medication. The housing has a patient-side port for coupling to a patient to provide ventilation including either air or air carrying aerosolized medication. A first path conducts air from the ventilator-side port through the moisturizing medium and the patient-side port, and a second path conducts air carrying aerosolized medication from the ventilator-side port directly to the patient-side port. A two-way valve mechanism in the housing selectively couples the ventilator-side port into fluid communication with one or the other of the first and second paths.

  • Patent number: 7866320
    Abstract: A nasal cannula and mouthpiece assembly for delivering oxygen to a person is provided having a nasal cannula, at least two mouthpieces, two pairs of oxygen supply tubes and two sets of adjustors. Each mouthpiece has a first outer end for receiving oxygen and a second outer end with a first and second opening. The first opening delivers oxygen across lips of a mouth of the person and the second opening delivers oxygen inside the mouth from the sides. A sleeve member encloses each of the mouthpieces and positions the mouthpieces in front of the sides of the mouth. The oxygen supply tubes of the first pair deliver oxygen to the nasal cannula and those of the second pair deliver oxygen to the first pair and to the mouthpieces. The two sets of adjustors adjust the lengths of the oxygen supply tubes of the first pair and the mouthpieces to provide a desired fit of the assembly on the person.

  • Patent number: 7828780
    Abstract: Low profile adaptor for use with a medical catheter, such as a gastrostomy feeding tube. In a preferred embodiment, the adaptor comprises a body having a lower portion and an upper portion. A first channel is provided in the lower portion, and a second channel is provided in the upper portion, the first and second channels being perpendicular to and in fluid communication with one another. A generally cylindrical stem is coaxially positioned within the second channel, the stem being rotatably mounted about its longitudinal axis. The stem is hollow and has an open front end, a closed rear end and a hole in its side wall, the hole being rotatably alignable with the first channel. To facilitate rotational alignment of the hole with the first channel, a stop is formed on the exterior of the stem, the stop being engageable with a surface positioned within the second channel. The front end of the stem is recessed relative to the front end of the second channel to prevent unwanted rotation of the stem.

  • Patent number: 7823585
    Abstract: A snorkel clip made up of two substantially rigid elements, which are designed to wrap at least half way around a snorkel tube, overmolded with a substantially flexible element to create a simple, aesthetically pleasing device. The snorkel clip also includes a hinge region created as part of the substantially flexible element. This hinge region allows the snorkel clip to flex or bend so that one of the rigid elements may be disengaged and pulled away from the riser tube of the snorkel, so that a mask strap may be attached to and removed from the snorkel, while the other rigid element remains attached to the riser tube in a generally secure manner. The substantially flexible portion may also include several cut out sections to provide visual and tactile access to portions of the substantially rigid elements for utility and aesthetic design.

  • Patent number: 7798147
    Abstract: Disclosed is a flow control device for a bronchial passageway. The device can includes a valve member that regulates fluid flow through the flow control device, a frame coupled to the valve member, and a membrane attached to the frame. At least a portion of the flow control device forms a seal with the interior wall of the bronchial passageway when the flow control device is implanted in the bronchial passageway. The membrane forms a fluid pathway from the seal into the valve member to direct fluid flowing through the bronchial passageway into the valve member.

  • Patent number: 7743770
    Abstract: A cannula having at least three separate flow passages and comprising separate nasal and mouth main bodies. The nasal body has first and second nares and first and second main flow chambers respectively communicating with first and second ports, and the first and second flow chambers are separated from one another by a septum. The mouth main body is adjacent the nasal main body and has at least one mouthpiece and at least a third main flow chamber therein communicating with a third port. The cannula has at least first, second and third flow paths which can be connected with a desired supply, monitoring or detection device. The invention also relates to the method of manufacturing the cannula.
