  • Patent number: 11116901
    Abstract: Missed meal bolus reminders or alerts require a user to access the user's pump and/or remote control to clear the reminder/alert even when the user skipped a meal such that no meal bolus was needed. CGM data can be leveraged such that the missed meal bolus alert is only triggered when glucose levels rise in response to consuming the meal within the programmed time window. Therefore, the alert is only provided when a meal is actually consumed and no bolus has been delivered. This further allows the user to be alerted sooner, i.e., as soon as glucose levels rise a predetermined amount or passed a predetermined threshold indicating consumption of a meal as opposed to only at the end of the programmed window.

An injectate delivery system includes a syringe for holding an injectate and a conduit configured at one end to be connected to a catheter. A flow measurement device is interposed in the conduit to generate a signal for determining the flow rate of the fluid from the syringe to the catheter. A processor receives the signal from the flow measurement device and calculates the injectate volume to be used as input for calculating a transpulmonary thermodilution parameter such as cardiac output. A GUI is provided to direct a user on whether the injection rate is too fast or too slow. Rather than measuring or calculating flow rate, a system may include a constant flow valve to provide a constant flow rate from the syringe.

Moreover, the clamping portions can be moved with respect to each other into an opened relative position in which the hose arranged between the clamping portions is not pinched off, so that the medium is able to flow through the interior of the hose. The pump is distinguished in that a sensor is provided thereon, in particular in the seating for the hose clamp, which sensor detects at least when the hose clamp is received in the seating—whether their clamping portions are in the closed or opened relative position.

  • Patent number: 10722658
    Abstract: A reusable medication delivery device that can determine medication remaining in a simple fashion. The device includes a first sensor (200) for sensing when a cartridge is mounted in the device, and at least one second sensor for sensing a retraction of a drive member (160) that engages a cartridge plunger (132). The device includes a controller that determines, based on inputs from the first sensor and the at least one second sensor, that a newly installed cartridge is to be considered full or not full of medication. The controller calculates, after a medication delivery and based on an input from a means for determining an amount of medication delivered by operation of a dose delivery mechanism, and if the cartridge was considered full when newly installed, a quantity of medication remaining in the installed cartridge after the medication delivery.

  • Patent number: 10646660
    Abstract: A method and apparatus are provided for use in locating a target region which is situated in the body of a subject, for example for the delivery of drugs. The system includes an assembly for controlling the flow of fluid from a fluid reservoir to a conduit, such as a needle. A sensor detects a characteristic indicative of the fluid pressure in the conduit. The system processes data from the sensor to detect the presence of a pulsatile waveform. A controller may control further operation of the system based on information regarding the presence of the pulsatile waveform and features of the waveform, such as amplitude.

  • Patent number: 10610643
    Abstract: Methods, devices, and systems of delivering infusion fluid (e.g., medication such as insulin) can detect, at multiple times during a dispensation period of time, a pressure level of the infusion fluid in an infusion fluid pathway, either directly or indirectly. Based on the detected pressure levels, one or more actual dispensation times that are after an intended dispensation time can be determined. In some cases, methods, devices, and systems provided herein can use variable occlusion alarm thresholds, which can depend on variables such as an age of an infusion set and/or a current analyte level. In some cases, methods, devices, and systems provided herein can automate medication delivery and use the actual dispensation times in a control algorithm determining medication deliveries.
