  • Drug delivery system and a method for operating a drug delivery system
    Patent number: 11426518
    Abstract: An inventive drug delivery system includes a reservoir that holds a drug to be administered. A drug applicator injects or infuses the drug, and a pump generates a flow of the drug from the reservoir to the drug applicator. A control system has a pressure sensor that measures pressure signals indicative of resistance against the flow of the drug and a processor is in communication with the pressure sensor. The control system detects with the pressure sensor a pressure signal indicative of the resistance against the flow of the drug while the drug is being administered and compares the measured pressure signal to a reference value. The control system also generates display data and provides it to an output device when the measured pressure signal exceeds the reference value. The display data includes a scheduled test reminder for a glucose level test that is communicated to an output device.

  • Integration of infusion pump with remote electronic device
    Patent number: 11383027
    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.

  • Flow control system
    Patent number: 11376412
    Abstract: A clamping mechanism (30) for clamping a flexible tube comprises two rotatable bobbins (22, 32), each with a tube-engaging surface portion (24) defining boundaries of a free space through which a tube may extend. The shape of the tube-engaging surface portion (24) changes around the bobbin circumference, such that axial rotation of the bobbins (22, 32) reduces the free space and thereby squeezes the tube. This allows the flow through the tube to be altered dependent on the rotation of the bobbins.
