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.

An autoinjector including a housing; an axially fixed product container; a torsion spring; a drive element; a propulsion element; and a needle protection sleeve is configured such that when the autoinjector is pressed against an injection location, the needle protection sleeve undergoes an actuation movement in the proximal direction. For discharging liquid from the product container through an injection needle into the injection location, the torsion spring sets the drive element into rotation and the rotating drive element causes a movement of the propulsion element and a piston in the product container in the distal direction. The autoinjector includes a coupling which, due to the actuation movement of the needle protection sleeve, releases the drive element for rotation, where the coupling is between a first and second coupling element in an engagement of locking surfaces, and can be disengaged by an axial coupling stroke of the two coupling elements.

A system and apparatus for the collection of serous or serosanguinous fluid from a percutaneous site after surgery. A pump unit with one or more pumps or powered sources provide continuous negative pressure suction to draw fluid from the percutaneous site and pumps the fluid into disposable reservoirs with one-way valves that are easy to handle while maintaining sterility and a seal to prevent the loss of vacuum. Air is continuously removed from the reservoirs. Measurement and analysis of the output is performed automatically. Additionally, through such a peristaltic pump device, controlled collection of measured surgical and/or bodily fluid from a subject patient may be undertaken allowing for more effective and closer analysis, as well.

Systems, apparatuses, and methods for providing negative pressure and/or instillation fluids to a tissue site are disclosed. Some embodiments are illustrative of an apparatus or system for delivering negative-pressure and/or therapeutic solution of fluids to a tissue site, which can be used in conjunction with sensing properties of fluids extracted from a tissue site and/or instilled at a tissue site. For example, an apparatus may comprise a dressing interface or connector that includes a pH sensor, a humidity sensor, a temperature sensor and/or a pressure sensor embodied on a single pad within the connector and proximate the tissue site to provide data indicative of acidity, humidity, temperature and pressure. Such apparatus may further comprise algorithms for processing such data for detecting leakage and blockage as well as providing information relating to the progression of healing of wounds at the tissue site. An illustrative method may comprise positioning a dressing interface having a pH sensor, a temperature sensor, a humidity sensor, and a pressure sensor at a tissue site, and applying reduced pressure to the dressing interface to draw fluids from the tissue interface in contact with the sensors to sense the pH, temperature, humidity, and pressure properties of the fluids flowing from the tissue site. The method may further comprise providing fluid data indicative of such properties to a processing element for processing the fluid data, and transmitting the data to another component in the system.

A system for at least partial closed-loop control of a medical condition is disclosed. The system includes at least one medical fluid pump. The medical fluid pump including a sensor for determining the volume of fluid pumped by the pump. Also, at least one continuous analyte monitor, and a controller. The controller is in communication with the medical fluid pump and the at least one continuous analyte monitor. The controller includes a processor. The processor includes instructions for delivery of medical fluid based at least on data received from the at least one continuous analyte monitor.

Systems, devices and methods are provided for the integration of an analyte data reader and a medication delivery device. The integrated device can include a medication delivery portion, wireless communications circuitry configured to receive data indicative of an analyte level, and electronics. The integrated device can also include one or more near-field communication (NFC) antennas. Example embodiments of adverse condition protection features of the integrated device are also provided.

This application relates to a wearable multi-shot injection patch. In one aspect, the patch includes a base that has a bottom surface and a top surface and is configured so that the bottom surface is disposed against a patient's skin. The patch may also include a first container that is supported by the base and accommodates a first drug, and a second container that is supported by the base and accommodates a second drug. The patch may further include a first pyrotechnic charge disposed between the top surface and the first container inside the base, and a second pyrotechnic charge disposed between the top surface and the second container inside the base. The patch may further include one or more electronic components configured to detonate the first pyrotechnic charge and the second pyrotechnic charge.

The operational parameters of a respiratory apparatus can be controlled through the use of a user interface located on a separate or separable mobile computing device. Sensors or features located on the mobile computing apparatus can be used to adjust the operation parameters or therapy of the respiratory apparatus or otherwise improve the compliance of a patient utilizing the respiratory apparatus.

The disclosure relates to a sensor system for detecting a position of a movable plunger in a drug delivery device, the sensor system comprising a sensor capable of detecting a magnetic field, the sensor adapted to be fixed within a housing of a drug delivery device, and a ferromagnetic or permanent magnetic component magnetically interacting with the sensor and adapted to move relative to the sensor as the plunger is moved.
