According to certain embodiments, an apparatus for applying negative pressure to a wound can include a negative pressure source, a sensor, and a controller. The negative pressure source can be configured to couple via a fluid flow path to a wound dressing and provide negative pressure to the wound dressing. The sensor can be configured to monitor a magnitude or frequency of pressure in the fluid flow path generated by the negative pressure source. The controller can be configured to determine an activity classification, such as breathing, changing positions while lying, sitting, walking, standing, jumping, traversing stairs, leg extending, leg bending, and performing chair squats, based on a change in the magnitude of pressure over time while the negative pressure source maintains the magnitude of pressure in the fluid flow path below a negative pressure threshold. The controller can output an indication of the activity classification.

A head mounted display and a control method thereof are provided. The control method includes the following. An eye-tracking operation is activated to obtain a gazing direction of a user. At least one setting position is set on a display frame, and the at least one setting position serves to set at least one static object. Whether to display or hide the static object is determined according to the setting position and the gazing direction.

A user feedback system for a user of a delivery device within a delivery ecosystem includes an estimation processor adapted to identify at least a first feedback action based upon one or more user factors, the at least first feedback action relating to an amount or nature of an active ingredient delivered by the delivery device, the feedback action being expected to alter a state of the user as indicated at least in part by the one or more user factors; and a feedback processor adapted to select at least a first identified feedback action, and to cause a modification of one or more operations of at least a first device within the delivery ecosystem, according to the or each selected feedback action.

A lactation system is disclosed. Embodiments include at least one extraction mechanism including a compression mechanism and a collection mechanism, and a controller. The compression mechanism can include a plurality of manipulable members, each operably coupled to an actuator and arrangeable circumferentially about a breast of a user such that each member can be actuated to selectively apply pressure to a region of the breast. The collection mechanism can be removably coupleable to the compression mechanism and can comprise a storage compartment to receive and store milk The controller can be operably coupleable to the actuators to cause the members to move according to a movement pattern which can be configured to stimulate the breast to induce the flow of milk from the breast and modulated based on sensor feedback. A wearable garment with an inner structure can be removably coupled to the extraction mechanism. An outer cover can be arrangeable to conceal the extraction mechanism.

Devices, systems, and methods for detecting a sealing condition between a patient interface and a patient, and adjusting the patient interface to maintain the patient interface in sealing contact with the patient. The patient interface may include a sealing structure to form a seal on the patient, and a positioning structure to secure the sealing structure to the patient. The patient interface may include a sensor coupled to the sealing structure. A processor determines the sealing condition between the sealing structure and the patient based on a signal from the sensor, and adjusts at least one of the sealing structure and the positioning structure to maintain the sealing structure in sealing contact with the patient. A prediction system predicts a leak between the sealing structure and the patient based on the sensor signal. A learning system learns how to fit the sealing structure to the patient to form a seal.

An intrathecal drug delivery system configured to monitor one or more physiological conditions of the patient to look for opportunities to time medicament delivery to coincide with patient activity inferring heightened cerebrospinal fluid oscillations, thereby improving dispersion of the medicament within the intrathecal space of the patient. The intrathecal drug delivery system includes an implantable medical pump, one or more physiological sensors, and an external programmer configured to program the implantable medical pump with a treatment protocol specifying at least one period of time during which a specified quantity of medicament is to be administered during which the implantable medical pump utilizes data from the one or more physiological sensors to time delivery of the medicament.

A system and method for operating an analgesia administration system is disclosed. A control device is associated with a drug delivery device and configured to receive a first user input including at least a portion of a fingerprint of a patient, together with a second user input corresponding to a request to administer medication. The portion of the fingerprint is compared with previously-stored fingerprints to determine an identity of the patient and, in response to receiving the second user input and determining that the patient is an authorized user, one or more sensors are used to obtain one or more signals indicative of a state of the patient. If the state of the patient satisfies a set of medication delivery criteria, the drug delivery device is caused to administer a predefined amount of medication to the patient.

This invention relates to a feedback predictive controller, systems comprising and methods employing the same. Preferably the feedback predictive controller and/or systems comprising the feedback predictive controller are part of an automatic insulin delivery system. The methods described herein can be used to control blood glucose concentration in a patient with diabetes. Preferably, the insulin delivery system is an artificial pancreas.
