  • Patent number: 9713674
    Abstract: Disclosed is a drug infusion system comprising a drug infusion device having a reservoir, a window for viewing the contents of the reservoir, a cannula arranged to be deployed beneath the skin of a patient, and an actuator configured to be manually actuated to drive a medicament from the reservoir to the cannula. The system also has a cannula cover and a needle handle that holds a needle for insertion into the patient. The cannula cover and needle handle are detachably attached to the drug infusion device, and each is attachable to the other. The device further comprises a septum and a septum pincher to seal the device. The device also comprises a pumping mechanism, part of which are a last-dose lock-out mechanism and an occlusion detection mechanism, both of which operate on the same actuator.

  • Patent number: 9387288
    Abstract: A drug infusion assembly comprises a drug delivery device arranged to adhere to a patient's skin and includes a reservoir that holds the drug, a cannula that delivers the drug to the patient, and a pump that causes the drug to flow to the cannula. The assembly further includes a monitor device for providing information about the operation of a drug delivery device. The monitor device includes a housing arranged to be attached to and detached from the drug delivery device, a sensor that senses the operation of the drug delivery device and generates an activation signal, a clock mechanism that generates a time signal, a memory that receives and stores the activation signal and the time signal and creates an information packet coordinating the time signal and the activation signal, an interrogator that interrogates the memory such that the memory generates a memory signal in response thereto, and a responder that receives the memory signal and generates a response.

  • Patent number: 8753315
    Abstract: A fully manually powered infusion device provides both basal and bolus delivery of a liquid medicament to a patient. In some embodiments, the device includes a main reservoir that supplies the liquid medicament, an outlet port that delivers the liquid medicament to the patient, a basal dispenser that delivers a substantially constant flow of the liquid medicament to the outlet port, and a manually actuated bolus pump that delivers a bolus dose of the liquid medicament from the main reservoir to the outlet when actuated. The basal medicament supply delivers a volume of the liquid medicament from the main reservoir to the basal dispenser consonant with each actuation of the bolus pump.
