  • Patent number: 9970853
    Abstract: An ultrasonic or acoustic viscosity sensor or viscometer is provided that can be used to accurately measure viscosity for fluid samples of less than 1 ?l in volume. Methods for measuring viscosity for fluid samples of less than 1 ?l in volume are also provided. The viscosity sensor and methods based thereon enable simultaneous measurement of bulk and dynamic (shear-rate dependent) viscosity of a non-Newtonian fluid. Bulk and dynamic viscosity of the non-Newtonian fluid can be measured simultaneously without separating constituents of the fluid, and thus distinguishing the effect of constituents on the viscosity. Dynamic viscosity of the non-Newtonian fluid can be estimated at varying shear rates, to study the deformability of the constituents of the fluid as a function of shear rate.

  • Patent number: 9962486
    Abstract: Occlusions in a delivery line of an infusion pump can be detected by measuring pressure differentials in the pump over short periods of time in order to minimize the effects of long term systematic sensor changes. In a delivery mode such as basal insulin delivery where a small portion of a volume of fluid is delivered, pressure readings can be obtained before and after the motor move to deliver each portion and compared. The differentials after one or more motor moves can be compared to determine whether an occlusion is present. In a delivery mode such as bolus insulin delivery in which an entire volume of fluid is delivered, pressure differentials can be obtained for consecutive deliveries at a common point in the delivery cycle of each delivery. Comparison of these pressure values can be used to determine whether an occlusion is present.

  • Patent number: 9539383
    Abstract: A system and method that identifies delayed infusion programs at an infusion pump or with a first computer and an infusion pump. The first computer receives an infusion auto-program from a remote source, transmits the infusion auto-program to the infusion pump, and sends a stale auto-program to the infusion pump. The infusion pump receives a manual infusion program, saves and executes the manual infusion program, and compares the stale auto-program to the manual infusion program to identify potential matches between the stale auto-program and the manual infusion program. The infusion pump evaluates the potential matches and determines if the potential matches are within a predefined tolerance, continues to execute the at least one manual infusion program on the infusion pump if the potential matches are within the predefined tolerance, and remotely saves differences in the manual infusion program and the at stale auto-program in a remote server for later analysis.
