Systems and methods are disclosed herein for switching an application executing on an ambulatory medical device to a new application without interrupting therapy provided by the ambulatory medical device to a subject. The ambulatory medical device may receive an indication that an update to an application executing on the ambulatory insulin pump is available, establish a communication connection to a host computing system, download and install the application update, while a prior version of the application continues to run. The disclosed systems and methods can confirm successful installation of the application update on the ambulatory medical device and switch control of the ambulatory medical device from the prior version to the new version of the application without interrupting therapy provided to the subject.

A patient interface for delivering breathable gas to a patient includes a sealing portion adapted to form a seal with the patient and a support portion to which the sealing portion is mounted. A first headgear chord is connected to a first side of the support portion, and a second headgear chord connected to a second side of the support portion. Headgear is adapted to connect to the first and second headgear chords to secure the support portion to a head of the patient. At least one adjustment device on the support portion is adapted to selectively move the first and second headgear chords to tighten or loosen the headgear.

A breast milk collecting method by stimulating the mammary gland of a breastfeeder to eject breast milk includes providing an audio-playing device to generate an auditory stimulation, providing a video-playing device to generate a visual stimulation, and providing a breast pump to generate a tactile stimulation and collect the breast milk. In this method, the breast pump is placed on a breast of the breastfeeder, and one or more deformable members of the breast bump is inflated or deflated alternately to touch and press the breast so as to mimic a breastfeeding condition to generate the tactile stimulation, so that the pituitary gland of the breastfeeder can be directly stimulated by the multiple sensory stimulations to secret prolatine or oxytocin, thereby allowing the mammary gland of the breastfeeder to eject the breast milk to be collected by the breast pump and treated collectively.

Methods and systems are provided for assisting a user of a wearable biosignal monitoring device (2) in adjusting the device to achieve optimum fit and positioning. The biosignal monitoring devices considered use integrated bio sensors (5) to monitor the user’s physiological activity for various purposes such as tracking daily activity patterns, determining mood, and monitoring sleep stages, among others. It is determined either during device setup or during primary use of the device whether the current fit and positioning of the device (2) enable the bio sensors (5) to properly sense the physiological signals needed for the device to perform its primary function. The user is then informed either after initial device setup whether adjustments need to be made in order to optimize device function during primary use, or is informed after primary use whether adjustments need to be made in order to improve device function during future primary use.

An example system for therapy delivery includes one or more processors configured to in response to a prediction indicating that the meal event is to occur, output instructions to an insulin delivery device to deliver a partial therapy dosage, to a device to notify the patient to use the insulin delivery device to take the partial therapy dosage, or to the insulin delivery device to prepare the partial therapy dosage prior to the meal event occurring, and in response to a determination indicating that the meal event is occurring (e.g., based on movement characteristics of a patient arm), output instructions to the insulin delivery device to deliver a remaining therapy dosage, to the device to notify the patient to use the insulin delivery device to take the remaining therapy dosage, or to the insulin delivery device to prepare the remaining therapy dosage.

An apparatus for controlling the flow of oxygen to a patient comprises an outer housing extending between first and second ends having a passage therethrough. The housing composes a first portion extending from the first end towards the second end and a second portion extending from the second end towards the first end wherein the second portion is threadably rotatable relative to the first portion so as to longitudinally displaced relative to the first portion under rotation thereof so as to adjust at least a portion of the passage extending therethrough adjusting a flow capacity of the passage. The apparatus further comprises connectors at each of the first and second ends operable to connect to oxygen conduits to fluidically conned the oxygen conduits to the passage through the housing.

A method of dispensing a therapeutic fluid from a line includes providing an inlet line connectable to an upstream fluid source. The inlet line is in downstream fluid communication with a pumping chamber. The pumping chamber has a pump outlet. The method also includes actuating a force application assembly so as to restrict retrograde flow of fluid through the inlet while pressurizing the pumping chamber to urge flow through the pump outlet. A corresponding system employs the method.

In an embodiment provided herein, an injection simulation device including a housing having a proximal end and a distal end is provided. The injection simulation device embodiment comprises a plunger having a proximal end, a distal end and being slidable relative to the housing, and a retractable injection simulation member at the distal end of the housing, at least one biasing member associated with the retractable injection simulation member and associated with the plunger, wherein a first force on a distal end of the injection simulation member causes movement of the injection simulation member from an extended position to a retracted position, to compress the first biasing member, and simulate the tactility of an injection to a user; and wherein a second force on the proximal end of the plunger asserts a third force on the first biasing member to facilitate resetting the injection simulation member to the extended position.

A fluid connector, including a fluid path portion having an integral cannula extending in a first direction from a interior surface, and a latching portion secured to the fluid path portion and having a pair of displaceable arms. Each arm includes a connector latch disposed at a first cantilevered end of the arm, and an activation lever disposed at an opposite cantilevered end of the arm and extending in a second direction, not parallel to the first direction. A portion of the activation lever includes a first lateral tactile feature aligned substantially parallel to the first direction to prevent forward slippage of the fluid connector from a user's grasp in the second direction, and a portion of the activation lever includes a lateral tactile feature aligned substantially parallel to the second direction to prevent slippage of the fluid connector from a user's grasp in the first direction.

Disclosed is a method of controlling operation of a medical device that regulates delivery of a fluid medication to a user. The method obtains a current sensor-generated value that is indicative of a physiological characteristic of the user, and is produced in response to operation of a continuous analyte sensor device. The method continues by: calculating a sensor quality metric that indicates reliability and trustworthiness of the current sensor-generated value; adjusting, in response to the calculated sensor quality metric, therapy actions of the medical device to configure a quality-specific operating mode of the medical device; managing generation of user alerts at the medical device in response to the calculated sensor quality metric; and regulating delivery of the fluid medication from the medical device, in accordance with the current sensor-generated value and the quality-specific operating mode of the medical device.
