An intravenous (IV) fluid delivery system include first and second IV bags and a fluid delivery device. The IV bags are made of many fluidic channels that keep the fluid distributed across the bags such that the bags may be easily and comfortably wrapped around the arm and shoulder of a person. The fluid delivery device includes a processor controlled electromechanical delivery mechanism that controls a positive displacement pump. The pump moves the fluid into a tube and a needle that is connected to a person's vein. The processor repeatedly turns the pump on or off to gradually transfer the fluid from the IV bags into the person's vein. The processor controls the granularity of the fluid delivery, where the fluid may be administered in a fluid delivery period, the fluid delivery may then be stopped in a subsequent fluid stoppage period, followed by other fluid delivery periods.

Disclosed is a medical device component for delivering medication fluid to a patient. The medical device component includes a fluid infusion device to regulate delivery of medication fluid, a body-mountable base unit, and a top cover assembly that is removably couplable to the base unit and to the fluid infusion device. The base unit includes a cannula to deliver medication fluid under the control of the fluid infusion device, and a physiological analyte sensor to measure a physiological characteristic. The base unit also includes an electronics assembly electrically connected to sensor leads to obtain measurements in the analog domain, to convert measurements into digital sensor data, and to communicate conditioned digital sensor data to the fluid infusion device. The top cover assembly is configured to provide both fluid and electrical connections for the base unit, by way of an infusion tube having sensor conductors integrated therein or otherwise associated therewith.

An apparatus comprising a pump configured to deliver insulin, a processor, and a user interface including a color display. Color on the display can be used to bring a user's attention to a change in status of the device or a detected change in status of the patient.

An ambulatory infusion pump can include a maximum bolus override procedure. When a bolus amount greater than a maximum bolus amount is requested, the pump can provide an alert indicating that the amount requested exceeds the maximum bolus amount. If the user confirms the request in response to the alert, the bolus amount can be delivered to the user. The amount delivered in response to the confirmation can be a first portion of the bolus amount. A reminder can then be provided that a second portion of the bolus amount that is a remaining portion of the requested bolus amount was also requested. If a second confirmation is received in response to the alert, the second portion of the bolus amount can also delivered to the user.

Medical devices and related patient management systems and parameter modeling methods are provided. An exemplary method of operating a sensing device associated with a patient involves obtaining current operational context information associated with the sensing device, obtaining a parameter model associated with the patient, calculating a current parameter value based on the parameter model and the current operational context information, obtaining one or more signals from a sensing element configured to measure a condition in a body of the patient, and providing an output that is influenced by the calculated current parameter value and the one or more signals.

Disclosed herein are systems and methods incorporating an ambulatory infusion pump and a CGM. These systems that can include software and related methods to provide improved automated insulin delivery algorithms that combine and/or filter CGM readings. Embodiments disclosed herein can combine and/or filter additional CGM readings received between therapy calculations by the algorithm to provide improved and more accurate insulin delivery. Methods can include filtering and/or combining CGM readings for a current dosing interval and/or or for past dosing intervals that are used to generate a predicted future glucose level to inform dosing.

A drug solution administration device includes a drug solution reservoir, a drive unit, a rotation detection unit, and a control unit. The control unit counts the number of rotations of the drive unit from when a rotation sensor value reaches a blockage start threshold value until the rotation sensor value reaches a blockage detection threshold value. Further, the control unit determines that a blockage of a flow path has occurred when the rotation sensor value reaches the blockage detection threshold value, and rotates the drive unit in a direction opposite to a direction in which the drug solution is administered based on the counted number of rotations.

A disposable wearable micro-flow continuous drug delivery system has an elastic drug storage cavity for extruding and storing liquid drug, wherein one end of the elastic drug storage cavity is communicated with a drug outlet pipe, wherein one end of the drug outlet pipe is communicated with a first micro-flow path and a second micro-flow path for shunting liquid drug, which is far away from the elastic drug storage cavity, wherein an adjusting mechanism is connected between the first micro-flow path and a second micro-flow path, wherein a first valve and a second valve are respectively provided at the surface of the first micro-flow path and adjacent to two different sides of the adjusting mechanism, wherein the disposable wearable micro-flow continuous drug delivery system of the present invention makes the liquid drug have a certain impulse by using the elastic and soft drug storage cavity, which is convenient to inject the liquid drug into the human body, and secondly, the adjusting mechanism is set between the two micro-flow paths, and a plurality of micro valves are set on the two micro-flow paths respectively, which enable the injection volume of the liquid drug to be controlled by controlling the switches of the micro valves located at different positions to help facilitate medical treatment and minimize the effect on the daily living activity of patients.

A valve assembly for a drug delivery device includes a valve housing having a first side and a second side positioned opposite from the first side, a cannula having a first end and a second end positioned opposite the first end, a pierce plate having a body and a piercing member extending from the body, with the body defining a coiled elongate member, and a valve boot connected to the valve housing and defining an interior space. The valve boot is configured to move from a pre-use position where the first end of the cannula and the piercing member of the pierce plate are received within the interior space to a use position where the piercing member of the pierce plate and the first end of the cannula extend outside of the valve boot and the interior space.
