  • Patent number: 11351344
    Abstract: A rigid hollow tubular adapter releasably attached at a longitudinal nozzle end to a flexible tube during equine nasogastric intubation comprising an annular sleeve having a stationary tubular member and a slidable tubular member. The slidable tubular member is delimited at its ends by the stationary tubular member and a detent member disposed between an equine reflux drainage hole and a longitudinal mouthpiece end. Operator's puffs of airflow through a mouthpiece urges the slidable member to slide toward the detent member closing the equine drainage hole to enable passage of medication into the equine stomach. Equine reflux urges the slidable tubular member to slide toward the stationary tubular member opening the reflux drainage hole to divert equine backflow downwardly through the equine backflow drainage hole preventing passage of equine reflux into the operator's mouth.

  • Publication number: 20140330228
    Abstract: A device for the drainage of a pleural effusion through an operatively engaged chest tube in the chest wall. The device employs a check valve situated between a vacuum source communicating with the chest tube to prevent reversal of the fluid flow out of the patient's body and possible contamination. A valve mounted on a vacuum bottle provides user control of communication of negative pressure from the vacuum bottle to the chest tube. Opening the valve on the bottle communicates negative pressure to the chest tube relative to the pressure in the tube thereby initiating a fluid flow out of the tube and the patient. Once the valve on the bottle is closed, fluid flow ceases and the check valve prevents reversal of the flow.

  • Patent number: 8608722
    Abstract: The present invention relates to a container for anal irrigation. In particular it relates to a rigid container which is easy to operate and which easily is transformed from a storage configuration to a ready-to-use configuration. In one aspect the invention relates to a container for an anal irrigation system. The anal irrigation system comprises an anal probe; a reservoir for holding an irrigation liquid (e.g. water); a pump mechanism for pumping a fluid (e.g. air) into the reservoir; and a liquid tube connecting the reservoir with the anal probe. The container comprises an outer chamber wall, defining at least partly the outer dimensions of the container and an inner chamber wall arranged within the outer chamber wall, said outer chamber wall and inner chamber wall defining the reservoir. This provides a reservoir having a small surface area when filled with irrigation liquid. Thus only a low pressure is necessary to evacuate the irrigation liquid from the reservoir and out through the anal probe.

  • Publication number: 20130331805
    Abstract: A portable, adjustable disposable medical suction system and method of use is disclosed. The system includes a delivery device to provide a conduit from a surgical site on a patient to the portable, adjustable medical suction system. The suction system may be a battery powered vacuum pump with one or more different adjustments directed to a strength of the vacuum, duration of the vacuum and interval between suction. The delivery device may be an intranasal tampon device or a tube inserted into the surgical site. During surgery and recovery at a surgical center or hospital, the vacuum source attached to the delivery system may be an industrial type vacuum source. Upon discharge, the suction system can be connected to the delivery system so that bleeding can be resolved by the patient in the comfort of his/her own home. The system and method of use is safer and mitigates body fluid borne contamination.

  • Publication number: 20130304007
    Abstract: An apparatus (10) for controlling flow of fluid from a wound site of a patient may include a chamber (28) connectable to a wound site and a reservoir (16). The chamber (28) may have a first deformed state, and a second state in which it is not deformed or less deformed than in the first state. The chamber (28) may be adapted to manage fluid flow between the wound site and the reservoir (16) during transition of the chamber (28) between the first state and the second state. An actuator element (64) of the apparatus (10) may be adapted to operate on the chamber (28) to transition the chamber (28) from the second state to the first state.

  • Patent number: 8540688
    Abstract: A portable device (2) to generate a vacuum for the medical treatment of wounds on the bodies of humans or animals has a vacuum-producing suction pump (90) in a first housing part (4) of the device and a vessel (10) for receiving body liquids. Vacuum is applied for vacuum communication between the suction pump (90), the vessel (10) and a suction tube (82) leading to the body. A pressure sensor (94) measures the pressure in a tube section (88) and a programmable electronic control unit (100) controls the suction pump (90) in dependence on pressure values measured by the pressure sensor (94). The electronic control unit (100) deactivates the suction pump (90) if a rate of change in pressure (?p/?t) detected by the pressure sensor (94) exceeds a defined threshold value toward decreasing vacuum.

  • Patent number: 8529532
    Abstract: Described generally herein are tissue therapy devices, which may comprise a sealant layer and a suction apparatus. The sealant layer functions so as to create a sealed enclosure between it and the surface of a patient by forming, preferably, an airtight seal around an area of tissue that requires negative pressure therapy. The tissue therapy device may comprise a suction apparatus. The suction apparatus is typically in fluid communication with the sealant layer and functions so as to reduce the amount of pressure present underneath the sealant layer. The reduced pressure is self-created by the suction apparatus. Together the sealant layer and the suction apparatus preferably create a closed reduced pressure therapy system. Preferably, the pressure under the sealant layer is reduced by expanding the volume of the enclosure space and thereby decreasing the density of the air molecules under the sealant layer.

  • Patent number: 8529526
    Abstract: Dressings, systems, and methods are disclosed in some embodiments that involve treating a tissue site with reduced pressure wherein the dressing includes a dressing reduced-pressure indicator that allows one to ascertain that the reduced pressure applied at the dressing is greater than a threshold reduced pressure. The dressing reduced-pressure indicator may include a moving member that is adapted to move under reduced pressure and a visual indicator associated with the moving member. Another embodiment uses an electro-mechanical indicator to provide a powered visual alert or audible alert or another output signal. Other dressings, systems, and methods are disclosed.

  • Patent number: 8506554
    Abstract: The invention relates to a tilt and slide cover in a vehicle roof. The tilt and slide cover comprises a cover and a frame, which is supported in lateral guides of a roof opening. The special feature of the tilt and slide cover lies in the fact that the cover is arranged relatively moveable in relation to the frame and can be locked to and released from this. The frame comprises a plastic section, into which the slide guide and other fittings such as slide cheek holders or the like can be integrated in one piece. It is also possible to fix the rear water collection channel directly on the frame.

    Abstract: A system for treating multiple tissue sites of a patient includes a first dressing filler adapted to be positioned at a first of the tissue sites. A second dressing filler is adapted to be positioned at a second of the tissue sites. A bridge manifold is positioned between the first tissue site and the second tissue site to provide fluid communication between the first and the second tissue site. A reduced pressure source is fluidly connected to at least one of the bridge manifold, the first tissue site, and the second tissue site. A valve is operably associated with one of the first and the second tissue sites to allow fluid to flow from the one of the first and the second tissue sites, but precluding flow towards the one of the first and the second tissue sites.

  • Patent number: 8444612
    Abstract: The composite wound dressing apparatus promotes healing of a wound via the use of a vacuum pump. The vacuum pump applies a vacuum pressure to the wound to effectively draw wound fluid or exudate away from the wound bed. The vacuum pump is tethered to the wound dressing and is portable, preferably, carried by the patient in a support bag, which permits patient mobility. Moreover, the patient does not need to be constrained for any period of time while exudate is being removed from the wound.
