  • Patent number: 11191684
    Abstract: A hybrid seating cushion made up of a cushion base and a cushion insert. The cushion base has a seating surface in which a void in or extending through the cushion base is formed. A cushion insert such as an air bladder or fluid sack is positioned within the void. A lip or upper surface around an opening in the void overhangs at least a portion of the cushion insert, thereby minimizing the size and corresponding negative effects of a transition area where the base and the insert overlap.
    Type: Grant

  • Publication number: 20100249727
    Abstract: A convenience kit which provides a basic configuration for use in measuring, filling and dispensing medication and flush solutions to IV sets and patient catheters through needleless connectors while improving safety and efficacy by requiring fewer post-sterilization makes and breaks compared to conventional filling and dispensing methods. Further, the kit improves flush compliance by facilitating dispensing of flush solutions and decreases likelihood of infections by providing for flushing of patient lines and catheter connecting fittings without line breaks. Convenience of operation is provided by a two-syringe assembly which is operable by a single hand for selective dispensing accomplished from either of the two syringes while obstructing flow from the other syringe. The kit comprises a clip for stabilizing the two syringe assembly.

  • Publication number: 20090194453
    Abstract: A convenience kit assembled and organized to measure, fill and dispense medication and flush solutions to patients through connections to patient lines and catheters while improving safety and efficacy of such procedures by requiring fewer post-sterilization makes and breaks when compared to similar filling and dispensing methods using conventional components. Further the kit improves flush compliance by facilitating dispensing of flush solutions and decreases likelihood of infections by providing for flushing of patient lines and catheter connecting fittings without any additional line breaks. The kit is provided in resealable, tamper evident kit packaging which permits sealed transport of kit parts after initial opening and follow-on parts use. Convenience of operation is provided by a two syringe assembly which is operable by a single hand by which selective dispensing is accomplished from either of the two syringes while obstructing flow from the other syringe.

  • Patent number: 7351223
    Abstract: A device for measuring fluid pressure in the lumen of a syringe including a pressure transducer integrally mounted in the plunger of the syringe under the plunger tip, such that the force applied by the plunger to the fluid in the syringe is transmitted to the transducer and the resulting electronic signal is converted to a display value for aiding a physician. A syringe that includes such a device may be placed in communication with a tubular member attached to a needle inserted into the body of a disk found in the spinal column of the back for diagnosing diseased disks in the back. The displayed pressure value may facilitate this diagnosis. Other uses of pressure applying monitoring syringes for other applications in communication with the body also benefit from the disclosed syringe construction, such as percutaneous translumenal angioplasty (PTA) procedures.

  • Patent number: 7291131
    Abstract: A syringe configured for communication with a tubular member insertable into the body of a subject includes a pressure transducer integrally mounted in the plunger thereof, under a tip of the plunger, such that the force applied by the plunger to fluid within a barrel of the syringe is transmitted to the transducer. A resulting electronic signal is converted to a display value for aiding a physician.

  • Patent number: 6996864
    Abstract: A cushion for a wheelchair, including a matrix of cushion modules, wherein each cushion module includes a cushion element that has a phase change material included in its filler material that sits above an additional cushion element of a larger volume of filler material. The cushion also typically includes a support rail located on three sides of the matrix of cushion modules to align the body of the wheelchair user when sitting in the wheelchair. In addition, the cushion typically includes a base member that is positioned beneath the matrix and provides stability for the cushion. The cushion elements are typically enclosed in a moisture resistant envelope.
