  • Patent number: 11937927
    Abstract: A transcutaneous sensor device configured for continuously measuring analyte concentrations in a host is provided. In some embodiments, the transcutaneous sensor device 100 comprises an in vivo portion 160 configured for insertion under the skin 180 of the host and an ex vivo portion 170 configured to remain above the surface of the skin 180 of the host after sensor insertion of the in vivo portion. The in vivo portion may comprise a tissue piercing element 110 configured for piercing the skin 180 of the host and a sensor body 120 comprising a material or support member 130 that provides sufficient column strength to allow the sensor body to be pushable in a host tissue without substantial buckling. The ex vivo portion 170 may be configured to comprise (or operably connect to) a sensor electronics unit and may comprise a mounting unit 150. Also described here are various configurations of the sensor body and the tissue piercing element that may be used to protect the membrane of the sensor body.

  • Patent number: 7653587
    Abstract: Computer-implemented methods are executed by a software application that allows users to create or edit account statements designated or queued for batch printing runs. This application also allows a test generation of a statement for confirmation of report formats assigned to the statement prior to the month-end statement generation. Finally, the application allows statements to be selected and grouped for generation based upon various account or corporate criteria. Once statements have been selected and generated, they may be sent to a quality review management program for final approval prior to batch printing.

  • Patent number: 7533053
    Abstract: A computer-implemented quality review process is introduced in which account statements may be individually selected from a batch printing run. Selected statements may then be viewed, edited, approved and released for printing. Account statements may also be unapproved, unreleased, purged or regenerated after one or more reviews are conducted. The quality review process includes the generation of various reports regarding the batch run and any results of the quality reviews.

  • Patent number: 6688364
    Abstract: Apparatus and methods for applying a transfer sheet to sign appliqueś and removing them to a sign board or other substrate. A carriage is movably mounted on a layout table. The layout table has a surface upon which appliqueś are arranged to be made into a sign. The carriage is constrained to move along the layout table in a fixed orientation, such as by using gear racks mounted on the frame. The carriage may have pinions that are mechanically coupled so opposing sides move in a coordinated manner. A transfer roll support allows the transfer sheet to play out and about an applicator which smooths the sheet onto the sign appliqueś. The apparatus includes elevators which allow elevation adjustment between the carriage and layout surface.

  • Publication number: 20030094731
    Abstract: An epidural injection is used in medical procedure to administer medication to a patient's epidural space in the spine, usually to alleviate pain. Although effective in purpose, current medical procedure to administer an epidural injection does contain a flaw that exposes the patient to possible infection, usually manifested as an epidural abscess or bacterial meningitis. A source for infection stems from the manner the epidural catheter, specifically the proximal end not being inserted into the patient, is traditionally handled throughout the procedure—usually freely hanging, susceptible to breaking the sterile field and becoming contaminated. The current invention, an epidural catheter dispenser system, seeks to eliminate this risk of epidural catheter contamination by maintaining the epidural catheter, especially the proximal catheter end, in a sterile dispenser that can be easily manipulated by a physician.

  • Patent number: 5440828
    Abstract: A manual snow removal tool has a blade, a pivotable handle, and a load transfer subassembly for structural rigidity and distributing force applied by a user through the handle to the blade. The load transfer subassembly defines an elongated channel, spaced from the handle pivot mount, through which the handle extends. The handle is slidable within the channel over a range of angular positions. The snow removal tool also has an angle adjustment mechanism for selectively positioning the handle at a desired angular position. The shovel can be used to scoop or windrow snow.

  • Patent number: 4924574
    Abstract: The disclosed unit is for use in improving the stoma wafer or face plate of an appliance worn by ostomates following surgery for ileostomy and the like. The unit comprises a base having a flat top surface which receives the wafer flat-wise thereon in a predetermined position relative to a gage which is engageable by a circular cutter that cuts a circular opening or hole in the center of the wafer, the diameter of the hole corresponding to a prior measurement of the diameter of the particular stoma. The gage is adjustably carried by the base to accommodate cutters of various diameters so as to enhance the versatility of the unit.
