| 20090036797 | FLAT LANCET IMMOBILIZATION - A lancet enclosed in a sterility sheet forms a lancet packet to maintain the sterility of the lancet and prevent the lancet from unintentionally piercing the sterility sheet prior to lancet actuation. In one form, the lancet is immobilized by hot tack welding a portion of the sterility sheet to the lancet. Alternatively, portions of the sterility sheet are hot tack welded together through an opening in the lancet to limit movement of the lancet. | 02-05-2009 |
| 20090105650 | DRUG DELIVERY PUMP DRIVE USING LINEAR PIEZOELECTRIC MOTOR - A drug delivery pump drive which uses a linear piezoelectric motor to advance a syringe piston to deliver a liquid drug and a method thereof are disclosed. The pump drive, provided in a drug delivery pump, provides silent operation and very low energy consumption compared to electric motor-based drives. The small size of the motor helps also to reduce overall size of the pump drive and the resulting drug deliver pump. | 04-23-2009 |
| 20090143730 | LEAD SCREW DELIVERY DEVICE USING REUSABLE SHAPE MEMORY ACTUATOR DEVICE - A drug delivery device drive that includes a single shape memory alloy wire actuator to advance a lead screw via a ratcheting mechanism and method thereof are disclosed. In one embodiment, a shape memory alloy wire is operably connected to one of a pair of ratchet wheels and configured to drive incrementally the rotation of the connected ratchet wheel via a contraction, which in turn drives the rotation of the other ratchet wheel about a rotational axis which moves a lead screw and advances a plunger to dispense a liquid drug from a drug container. A drug delivery device using the shape memory alloy wire actuator in combination with the ratcheting mechanism to incrementally rotate a shaft, a lead screw or a sleeve provides for a more compact an less complicated design. | 06-04-2009 |
| 20090143735 | DRUG RESERVOIR LOADING AND UNLOADING MECHANISM FOR A DRUG DELIVERY DEVICE USING A UNIDIRECTIONAL ROTATED SHAFT - A drug reservoir loading and unloading mechanism for drug delivery device using unidirectional rotated lead screw and method thereof are disclosed. The drug reservoir loading/unloading mechanism allows exchanging the drug reservoir quickly with very few steps and with more safety. The invention neither requires rewinding of the drive system either automatically or manually while replacing the drug reservoir nor requires an additional adapter to secure the drug reservoir. | 06-04-2009 |
| 20110137240 | HOLOGRAPHIC OCCLUSION DETECTION SYSTEM FOR INFUSION PUMPS - A holographic occlusion detection system has a white-light holographic label placed onto a sensing portion or surface of a pressure sensor connected to infusion tubing. The pressure sensor at the sensing portion can have a relatively thin wall section and may be wider and flatter than a normal cross section of the infusion tubing. The label is then illuminated by a polychromatic light source, and the light reflected off the holographic label is then received by a photodetector. Pressure changes within the tubing cause a change in orientation of the white-light holographic label, thereby resulting in a shift in the peak wavelength of the reflective light sensed by the photodetector. This shift in wavelength can then be calibrated to the swelling of the sensing portion so that pressure within the infusion line can be calculated. In another variation, monochromatic light is reflected off a holographic label, and pressure changes are detected by measuring the amplitude of the reflected light. | 06-09-2011 |

| 20110174644 | TEST STRIP CONTAINER WITH STRIP RETAINER AND METHODS OF MANUFACTURING AND UTILIZATION THEREOF - A test strip container with an insert comprising a channel and a retaining member and methods of manufacturing and utilization thereof are disclosed. The container includes a housing, an insert, a lid, and at least one retaining member in at least one channel. The at least one retaining member releasably retains a plurality of test strips in the at least one channel. | 07-21-2011 |
| 20110263006 | INTEGRATED TEST STRIP CONTAINER WITH RETAINING INSERT - A blood glucose meter for providing easy access to test strips and measuring blood glucose, a disposable and removable cartridge for providing easy access to test strips, and methods of manufacturing and utilization thereof are disclosed. The blood glucose meter for providing easy access to test strips and measuring blood glucose has a disposable and removable cartridge, a retaining member which releasably retains the test strips in a stacked configuration, and a housing. The disposable and removable cartridge has a rigid lid attached to a flexible body. | 10-27-2011 |
