  • Patent number: 11660388
    Abstract: A digital syringe is used with conventional polymer disposable syringe construction to be practical in the medical environment. Errors associated with the larger volumes of the syringes (which exacerbate minor errors in plunger position) and the flexibility and dimensional variations of the polymer plungers are accommodated by direct measurement of the syringe plunger position rather than indirect measurement of motor position and inference of syringe plunger position. This direct measurement eliminates mechanical tolerances (“stack up”) in the motor, gear train, and lead screw on plunger movement, an effect exacerbated by flexibility of the plunger and changes in syringe resistance and medicament viscosity, for example, with different medicaments or when the syringe is refrigerated. The digital syringe may be combined with the motor unit to provide additional versatility.

  • Patent number: 10780217
    Abstract: Ratchet-based drive systems for more reliable and safer drug delivery are provided. The ratchet-based drive systems restrict angular movement and/or linear movement of components that cause a plunger to expel a liquid drug from a drug container. Movement of the components can be restricted to correspond to a predetermined or desired portion of the liquid drug. In the case that control of the drive system is lost or fails, the maximum amount of drug that could be delivered is limited to a known amount, thereby reducing the likelihood of an overdose.

  • Patent number: 10744257
    Abstract: A method, computer program product, and infusion pump assembly for determining a first rate-of-change force reading that corresponds to the delivery of a first dose of an infusible fluid via an infusion pump assembly. At least a second rate-of-change force reading is determined that corresponds to the delivery of at least a second dose of the infusible fluid via the infusion pump assembly. An average rate-of-change force reading is determined based, at least in part upon the first rate-of-change force reading and the at least a second rate-of-change force reading.

  • Patent number: 10596325
    Abstract: A pen-type drug injection device is disclosed which comprises a housing having a longitudinal axis, a threaded piston rod, a guide member for guiding the piston rod in a drug dispense operation, and a cartridge holder for receiving a cartridge, wherein the cartridge holder is detachable from the housing and wherein the guide member comprises an iris type aperture defined by a plurality of threaded pivotable segments. The drug delivery device is configured such that the aperture increases in diameter when the cartridge holder is being detached from the housing, such that the piston rod is free of the threaded engagement with the guide member and can be reset or pushed back to its initial position, and decreases in diameter when the cartridge holder is attached, such that the threads on segments reengage the piston rod.

  • Patent number: 10532376
    Abstract: A dispenser with a transfer assembly is arranged to efficiently transfer a stored liquid from a reservoir in a body of the dispenser to an applicator. The transfer assembly includes an adapter, applicator base, piston and a bias member. The adapter is in contact with the body and has a central member with orifices to fluidly couple the applicator base to the reservoir. The applicator base is supported by and extends beyond the adapter. The applicator base forms a cavity for housing the piston and the bias member. A tubular member of the applicator base supports an applicator. The piston includes a passage that conveys the stored liquid from the cavity to the applicator. The bias member keeps the head of the piston against a surface of the central member. When stored liquid is under a pressure that exceeds a bias force, displacement of the piston, opens a seal.

  • Patent number: 10507319
    Abstract: A multi-use disposable set (MUDS) has at least one syringe having a proximal end and a distal end spaced apart from the proximal end along a longitudinal axis. The MUDS further has a plunger reciprocally movable within a syringe interior between the proximal end and the distal end. A manifold is in fluid communication with the distal end of the at least one syringe. At least one valve is in fluid communication with the syringe interior. The at least one valve is operable between a filling position for filling the syringe interior with fluid and a delivery position for delivering the fluid from the syringe interior. At least one connection port is in fluid communication with the manifold and the syringe interior when the at least one valve is in the delivery position. A multi-fluid delivery system having the medical convector and MUDS is also provided. Various features of the MUDS system are also described.

  • Patent number: 10266333
    Abstract: A delivery system having a telescoping spring is used to drive a plunger. The telescoping spring includes a nested inner spring that uses the unused volume on the inside of an outer spring. The telescoping spring has a staged release of each spring. The inner spring is connected to a non-anchored end of the outer spring, and rides within a container located within an inner dimension of the outer spring. The spring constant K of each spring can be the same or different. The delivery system can be fully mechanical or implemented as a smart delivery system under electronic control.
