  • Patent number: 10428506
    Abstract: Systems, devices, and methods for providing are refreshing wand with disposable rubby rinse head that can be washed and/or disposed that can be attached to a toilet water supply that can be used with toilet paper to remove vaginal discharge fecal matter material and urine that wiping was not able to remove. Toilet wash 1 as a dual shut off valve and toilet wash 2 use the existing shut off valve with the splitter. The valves can be used for supplying water to the refreshing wand with disposable rubby rinse head. The disposable rubby rinse head can be washed and/or disposed. The new disposable rubby rinse head replaces the need to replace the plastic tube because the silicone cover is the only piece that comes in contact with human waste.

  • Patent number: 8863772
    Abstract: The present invention generally relates to occluders and, in particular, to occluders for use in medical infusion systems. In one aspect, the occluder contains one or more tubes through which fluid can flow, and the occluder can be automatically controlled to allow or at least partially prevent fluid flow. In some cases, the occluder may be constructed and arranged to fail (e.g., due to loss of power) in a “closed” position, i.e., a position that at least partially prevents fluid flow. In addition, in one embodiment, the occluder may be manually overridden, even when in a failed state, by a user. For instance, in the event of a power failure, a user may be able to manually override the occluder to remove tubing from the occluder. Such occluders may find use, for example, in medical devices such as hemodialysis machines, medical infusion pumps, plasmapheresis devices, and the like.

  • Patent number: 8622978
    Abstract: Tools for determining and adjusting the setting of an adjustable valve are disclosed. These tools allow a medical professional to locate and non-invasively determine the setting of an implanted valve. After the valve has been located and the setting of the valve determined, the valve may be re-adjusted non-invasively. There are three tools: a locator tool, an indicator tool and an adjustment tool. The locator tool allows the physician to locate the adjustable valve of interest and align the locator tool with a specific orientation of the valve. The indicator tool indicates the current setting of the adjustable valve and confirms new settings of the valve after the new settings have been implemented. The adjustment tool interacts magnetically with the implanted adjustable valve to couple with a movable internal element to change the setting of the valve. The indicator tool and the adjustment tool physically cooperate with the locator tool to accomplish the respective functions of the tools.

A central hub manifold resides within a valve body supporting the ports, and can rotate relative to the valve body. Fluid flow paths within the central hub are selectively aligned or not aligned with the ports. The stopcock indicates which ports are open by providing marks corresponding with positions of the ports. When the marks are visible, the corresponding ports are open. With different positioning of ports and different configurations of fluid flow paths within the central hub, stopcocks having different numbers of operable positions are provided including two, three, four, six and eight way stopcocks. By providing an axial flow path through a central axis of the central hub intersecting the embedded fluid flow paths within the central hub, still further numbers of operational states are provided.

  • Patent number: 8568368
    Abstract: A contrast media delivery system having a flow regulator assembly that allows a practitioner to regulate the passage of contrast media into a burette while minimizing turbulence and the formation of microbubbles in the contrast media. The flow regulator assembly can be actuated by twisting a rotatable cap. When the rotatable cap is released, the flow of contrast media from the inlet to the burette is stopped. A diffuser having a contact surface is provided which disperses contrast media as it passes into the burette to ensure that the contrast media flows smoothly and uniformly down the wall of the burette and into the volume of contrast media. A float and seating assembly which provides optimal sealing of the outlet of the burette while also allowing separation of the float from the seat when the burette is being refilled with contrast media.

  • Patent number: 8529524
    Abstract: A gland member within a medical valve is configured to have a substantially consistent or enlarging internal volume as the valve transitions from a closed mode to an open mode. The valve has a housing forming an interior containing a flow path, and a stationary post member within the interior. The post member has a lumen that is a part of the flow path. The lumen has an opening to the interior of the housing. The valve further includes a gland member circumscribing the post member to produce a variable volume region formed at least in part between the gland member itself and the post member. The variable volume region is a part of the flow path, while the gland member occludes the post lumen opening when in the closed mode. The variable volume region has an open volume that is no less than its closed volume.

    Abstract: A dosing unit for an ambulatory infusion device and a method of operation are disclosed. The dosing unit includes a stationary member, a movable member, and a plunger. The movable member and the stationary member, together, make a charging valve and a discharging valve. The plunger is located, at least in part, in a metering cavity of the movable member and the movable member is adapted to selectively couple and decouple a driving unit, such that, by operating the driving unit with the movable member being coupled with the driving unit, the movable member moves with the plunger to maintain a position of the plunger relative to the movable member along a displacement axis, and by operating the driving unit with the movable member being decoupled from the driving unit, the plunger is displaced while the position of the movable member is maintained.

  • Patent number: 8491541
    Abstract: A valve assembly for use with a catheter assembly is provided. The valve assembly includes a valve housing defining a longitudinal axis and adapted for fluid engagement with a catheter assembly. The valve housing has an internal passageway for flow of fluids relative to the catheter assembly. A valve member is at least partially disposed within the valve housing and defines a valve passage. The valve member is adapted for movement within the valve housing between an open position wherein the valve passage is in general alignment with the internal passageway of the valve housing to permit flow of fluids through the valve housing, and a closed position to substantially occlude the internal passageway of the valve housing. An actuation mechanism is selectively movable in a general longitudinal direction to cause corresponding movement of the valve member between the open position and the closed position.

  • Patent number: 8491540
    Abstract: The illustrative embodiments described herein are directed to apparatuses, systems, and methods for managing liquid flow associated with a tissue site that involves using reduced pressure to control fluid flow. In one instance, an apparatus includes a first valve and a second valve in fluid communication with a reduced-pressure source. The valves are movable between an open position and a closed position and are operable to change flow status (open to closed or vice versa) based on a presence of reduced pressure. At least one of the first valve or the second valve is in the closed position to obstruct a flow of a liquid while the other is in the open position. The apparatus also includes a reservoir fluidly coupled to the first valve and the second valve. Other systems, methods, and apparatuses are presented.

  • Publication number: 20130138075
    Abstract: A device, system and method are provided for controlling the rate of infusion of fluids during infusion therapy using non-electric infusion devices. Rotation of a flow regulator dial causes an orifice connected to the inlet to modify its position relative to a particular one or more orifices or groove portions, the characteristics of which provide a certain flow rate characteristic. The regulator allows for the infusion pump to infuse at a rate that may be varied during use by the user.
