A medical tube management system, kit, and method of use; including a fastener, a length of tubing, and a releasable spring to retain and release slack in the tubing when accidentally tugged. The fastener being universal and interchangeable, able to connect various springs. The spring is capable of reversibly restricting flow in the tubing when uncoupled from the fastener. The fastener is capable of notifying the patient, or care taker, when the system has been tugged into the uncoupled position.

A dialysis machine (e.g., a peritoneal dialysis (PD) machine) can include a pressure sensor mounted at a proximal end of a patient line made of a distensible material that provides PD solution to a patient through a catheter. During treatment, an occlusion can occur at different locations in the patient line and/or the catheter. When an incremental volume of additional solution is provided to the patient line while the occlusion is present, a change in pressure results. The change in pressure depends on the dimensions and the distensibility of the non-occluded portion of the patient line. If the change in pressure, the incremental volume, the properties related to the distensibility of the patient line, and some of the dimensions of the patient line are known, the location of the occlusion can be inferred. The occlusion type can be inferred based on the determined location.

An infusion device (1) for administering a medical fluid to a patient (P) comprises a pump mechanism (11) for administering a medical fluid to a patient (P) through a line set (3), a sensor device (14) for measuring a measurement value indicative of a pressure in the line set (3), and a processor device (15) configured to automatically set, in an initial phase, a threshold value (15) to a value determined based on at least a mechanical characteristic of the line set (3) and/or the pump mechanism (11) and to determine, in an operational phase, whether an occlusion condition in the line set (3) is present based on the measurement value and the threshold value (P.sub.thres) —Herein, the processor device (15) is configured to adjust the threshold value (P.sub.thres) if in the operational phase a pressure variation condition in the line set (3) different than an occlusion condition is detected by the processor device (15). In this way an infusion device is provided which may be able to reliably detect an occlusion condition even in case of multiple infusion devices acting on a line set in a multiline infusion.

A wearable drug delivery device for monitoring unintended over-delivery and/or under-delivery of a stored liquid drug are provided. An absolute pressure sensor can be positioned within the fluid path of the drug delivery device. The absolute pressor sensor can detect both ambient pressure (e.g., absolute or atmospheric pressure) and relative pressure (gage or pumping pressure). Based on the detected pressures, the effects of external ambient pressure on air with the fluid path can be determined during both intended drug delivery events and unintended drug delivery events. In turn, under-delivery and/or over-delivery of the liquid drug can be determined. Based on the severity of the determined under-delivery or over-delivery of the liquid drug, alarms indicating different urgencies can be provided to the user.

An infusion pump includes a housing with a door pivotally mounted to the housing, a tube channel on the housing configured to hold a tube in the infusion pump, a pumping mechanism including a shuttle, and a slide clamp ejection device.

A method for managing use of a disposable with an infusion pump is provided. The method can include adding validity information about a particular set of disposables to a list of disposables. Subsequent to adding the validity information, the method can include modifying the validity information about the particular set of disposables on the list of disposables. The method can include an infusion pump reading identifying information from a disposable, and can include determining whether the disposable is valid for use, based at least in part upon comparison of the identifying information read from the disposable by the infusion pump with the validity information about the particular set of disposables on the list of disposables. The method can also include the infusion pump making a determination of whether to deliver or not deliver an infusate based at least in part upon the determining whether the disposable is valid for use.

A method, computer program product, and infusion pump assembly for determining a first rate-of-change force reading that corresponds to the delivery of a first dose of an infusible fluid via an infusion pump assembly. At least a second rate-of-change force reading is determined that corresponds to the delivery of at least a second dose of the infusible fluid via the infusion pump assembly. An average rate-of-change force reading is determined based, at least in part upon the first rate-of-change force reading and the at least a second rate-of-change force reading.

A medical liquid injection device may include a pump module, a pivot fitting, at least one sensor, and a processor. The pump module may include a shaft configured to perform a linear reciprocating movement along one direction. The pivot fitting may include a first end connected to the shaft and a second end configured to perform a rotational reciprocating movement by the linear reciprocating movement. The at least one sensor may obtain contact time information on a time at which at least one sensor comes into contact with the second end. The processor may calculate a driving time of the pump module using the contact time information and determine occurrence of occlusion of the medical liquid injection device on the basis of the driving time.

A wearable infusion pump assembly includes a reservoir for receiving an infusible fluid, and an external infusion set configured to deliver the infusible fluid to a user. A fluid delivery system is configured to deliver the infusible fluid from the reservoir to the external infusion set. The fluid delivery system includes a volume sensor assembly, and a pump assembly for extracting a quantity of infusible fluid from the reservoir and providing the quantity of infusible fluid to the volume sensor assembly. The volume sensor assembly is configured to determine the volume of at least a portion of the quantity of fluid. The fluid delivery system further includes a first valve assembly configured to selectively isolate the pump assembly from the reservoir, and a second valve assembly configured to selectively isolate the volume sensor assembly from the external infusion set.

Sensors, methods, and computer program products for air bubble detection are provided. An example method includes determining a first moving average for a first period of time based upon first temperature data and determining a second moving average for the first period of time based upon second temperature data. The method includes determining a first air presence parameter based upon a comparison between the first temperature data and the first moving average and a comparison between the second temperature data and the second moving average. The method includes determining a second air presence parameter based upon a comparison between the first temperature data, the second temperature data, and calibrated air thresholds. The method includes determining a third air presence parameter based upon a comparison between a first temperature data entry and each second temperature data entry. An air bubble within a fluid flow system is detected based upon the parameters.
