  • Patent number: 11911590
    Abstract: A system and method can provide for a remote electronic device to be used to remotely initiate delivery of a medicament bolus with a medical device, such as an insulin pump, with the medical device providing audible or tactile confirmation of the programmed bolus. The bolus amount can be calculated by or programmed or otherwise entered into the smartphone, etc., and then transmitted to the medical device. When the pump receives the transmitted bolus amount, it issues one or more indications such as audible sounds and/or vibrations in any number of desired combinations. For instance, each individual sound or vibration may correspond to an increment of the medicament. The user can therefore determine the size of the medicament bolus by the number of sounds or vibrations and can confirm or cancel delivery of the bolus.

    Abstract: An auto-injector for injecting a fluid medicament into a patient from a pre-filled syringe requires a disposable cassette that is selectively engageable with the reusable injector. The syringe is latched onto the cassette, and the cassette is then engaged with the injector. Activation of the injector causes a first motor to move the syringe so its needle is extended from a concealed position inside the cassette for injection of the medicament. A second motor on the injector is then activated to expel fluid medicament from the syringe. Then, the first motor is again activated to withdraw the syringe into the cassette for disposal of the cassette/syringe after an injection.

  • Patent number: 9962500
    Abstract: The invention faces the technical problem of providing a tight connection between a tube and an dispense interface, while at the same time the biocompatibility of the connection can be improved. The technical problem is solved by an apparatus comprising a tube configured to guide a medium and a dispense interface. The tube comprises a first opening and a second opening, while the dispense interface comprises a recess. The recess has a first opening and a second opening and the tube is at least in part inserted into the recess. The tube is permanently affixed to the dispense interface by a combination of an interference fit and an adhesive, such that the interference fit prevents the adhesive from contaminating the medium.

  • Patent number: 9737656
    Abstract: A system and method can provide for a remote electronic device to be used to remotely initiate delivery of a medicament bolus with a medical device, such as an insulin pump, with the medical device providing audible or tactile confirmation of the programmed bolus. The bolus amount can be calculated by or programmed or otherwise entered into the smartphone, etc., and then transmitted to the medical device. When the pump receives the transmitted bolus amount, it issues one or more indications such as audible sounds and/or vibrations in any number of desired combinations. For instance, each individual sound or vibration may correspond to an increment of the medicament. The user can therefore determine the size of the medicament bolus by the number of sounds or vibrations and can confirm or cancel delivery of the bolus.

  • Patent number: 9675751
    Abstract: A reservoir and straight-line, push-on connector assembly is provided for connecting the reservoir and one of a standard Luer line set and a custom Luer line set to any number of infusion pump configurations using a simple straight-line, push-on motion, wherein the push-on connector assembly is provided and configured to secure the line set and reservoir with the infusion pump. One simple straight-line, push-on motion, preferably performed by gripping an expander sleeve, places and secures the reservoir (i.e., locates the reservoir on the x, y, and z axes) in the pump reservoir cavity, and one simple straight-line, pull-off motion releases and removes the reservoir from the pump reservoir cavity. Rotational orientation is not required for connection, pump engagement, or pump function, and any pulling of the tube set will not release the reservoir as the expansion sleeve through which the tube set is routed is not moved from the securing position by tension on the tube set or Luer fitting.
