Robert Purdy has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9119760
    Abstract: The present invention relates to a support for a body part including a compression device in combination with a lower leg protection system. The compression device can be integral with the outer support at a position received over the lower leg. One or more valves can extend from a compression bladder for attachment to a pneumatic device. Inflation of the compression bladder positioner adjacent the lower leg also displaces air in the outer support toward the foot which causes simultaneous massaging of the foot. The pneumatic device can be adjusted to provide either sequential or intermittent therapies.

  • Publication number: 20150105707
    Abstract: The present invention relates to a fluidized lower leg protection and support system and method. The system can include an inner positioner. The inner positioner can displace and contour three-dimensionally as though it was fluid to the sides and top of the leg while not having flow characteristics that would result in migration of the medium under the force of gravity. The system can also include an outer support which is received over the inner positioner. The outer support can be in the shape of an open boot. The outer support can include an ultra low pressure plenum. The ultra low pressure plenum is filled at a predetermined low pressure for distributing pressure along the length of the outer support, but not providing significant elevation of the lower leg and heel by itself.

  • Publication number: 20120311781
    Abstract: The present invention relates to a system and method for sacral and trochanteric support and off-loading. The system provides a ultra low pressure plenum and a positioner. The patient body size and size and corresponding surface area of the positioner control the amount of gas which is displaced evenly against the walls of the ultra low pressure plenum to allow the combination of the ultra low pressure plenum and the positioner to slightly lift a patient from a bed surface, thereby offloading the sacrum and trochanter.

  • Publication number: 20120311787
    Abstract: The present invention provides a method and system for customization of flow characteristics of a support using permanent and controlled evacuation of interstitial gas during the manufacturing process. The flow characteristics can be customized to provide a stiffer or less stiff support by a comparative degree. The flow characteristics can be permanently changed. The support includes a bladder filled with a fluidized particulate material. The medium of the fluidized particulate material includes interstitial spaces. A predetermined amount of gas can be removed to provide a support having a desired specific support characteristic.

  • Patent number: 7998122
    Abstract: An improved luer lock receiving septum having a configuration which provides rapid and tight resealing and yet allows penetration of the septum by the luer tip with a low penetration force. The elongated septum includes an upper portion of enlarged diameter having a target surface, a central slit, and a central, lower septum extension projecting about the slit below the upper portion and into a housing so that following luer insertion there is provided sufficient room for both the laterally displaced extension of the septum, the luer taper, and the housing to be received into a conventional luer lock connector. The septum is further preferably configured to minimize or eliminate the negative pressure deflection normally associated with the withdrawal of the large diameter luer cannula from an enclosed fluid filled lumen or chamber, by substantially isolating the lumen or chamber from the septum material displacement resultant from luer insertion.

  • Publication number: 20070083995
    Abstract: The present invention provides a fluidized positioning system including an inner bladder formed of a medium that has no memory or substantially no memory. An outer bladder is placed adjacent to or coupled to the inner bladder. The outer bladder is partially filled with a composition. The composition can be beads, such as polystyrene beads, or beads made of a similar medium. A valve extending from the outer bladder permits the evacuation of all or some of the air from the outer bladder which causes the outer bladder to be reduced in size due to loss of air between the beads and adjusts the rigidity of the outer bladder to allow the outer bladder to form fit the inner bladder around whatever body extremity it is being used on.

  • Patent number: 6866656
    Abstract: A lubrication system is disclosed which minimizes friction and that is useful for application on the surface of a flexible portion of a medical device. Such a lubrication system includes a lubricant that is able to move when the flexible portion of the medical device flexes and is biocompatible and is not degraded by the application of alcohol or other conventional medical sterilizing and cleaning agents. The lubricant is bonded to the surface of the flexible portion of the medical device. The lubrication system may be used on an elastomeric septum, such as a silicone rubber elastomer. The lubricant coating may be any type of coating that can be chemically bonded to the elastomer, such as di-paraxylene, poly-(p-xylene), polytetrafluoroethylene, or polyvinylpyrrolidone.

  • Publication number: 20020184162
    Abstract: Services and resources hosted by more than one originator are distributed to a plurality of consumers. To facilitate the distribution of the services and resources, the reseller contains host access information for each originator to which the reseller is authorized to access resources. Upon receipt of consumer access information to an authorized consumer, the reseller provides host access information to each originator hosting resources the authorized consumer is authorized to access. Each originator receiving host access information from the reseller will permit the authorized consumer access to the resources and services. In this way, a reseller provides a “virtual host” to consumers by reselling services and resources from different originators. An originator may also be a reseller of those services and resources of other originators. The originators and resellers are identified by unique randomly created identifiers to maintain their identities confidential.

  • Patent number: 5797882
    Abstract: An arterial catheter includes an elongate tube having a sidewall with an inside surface and an outside diameter. The catheter has a proximal end, an open distal end with a tip portion, and a hollow bore with an inside diameter. There is a hub attached to the proximal end of the catheter that is in fluid communication with the hollow bore. The inside surface of the hollow bore has a plurality of inward projections disposed longitudinally from the proximal end to the distal end. The tip portion has at least one hole through the sidewall into the bore. The catheter sidewall outside diameter is tapered distally from the hole to the open distal end and the inward projections on the inside surface of the bore are substantially diminished in the tip portion.

  • Patent number: 5535771
    Abstract: A valved adapter for a medical access device includes a body with a longitudinal axis. The body has a proximal first end, a distal second end and a passageway therethrough which has an inside surface. The passageway has a chamber defined by a proximal shoulder and a segmented distal shoulder both projecting inwardly from the surface of the passageway. The chamber is located intermediate the first end and second end of the body. The adapter includes a valve contained within the chamber for selectively obstructing and allowing fluid flow through the passageway. The valve includes an elongate resilient member with an axis substantially coaxial to the longitudinal axis of the body having a proximal end and a distal end. The elongate resilient member is axially compressed between the distal shoulder and the proximal shoulder, the compression biasing the valve to a normally closed position.
