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.

Systems, devices, and techniques are disclosed for administering and tracking medicine to patients and providing health management capabilities for patients and caregivers. In some aspects, a method includes receiving one or more analyte values associated with a health condition of the patient user; receiving contextual data associated with the patient user obtained by the mobile computing device, where the obtained contextual data includes information associated with a meal; determining a medicine metric value associated with an amount of medicine active in the body of the patient user; autonomously calculating a dose of the medicine without input from the user based at least on the one or more analyte values, the medicine metric value, and the information associated with a meal; and continuously displaying the calculated dose of the medicine.

An overdose of opioids can cause the user to stop breathing, resulting in death. A physiological monitoring system monitors respiration based on oxygen saturation readings from a fingertip pulse oximeter in communication with a smart mobile device and sends opioid monitoring information from the smart mobile device to an opioid overdose monitoring service. The opioid overdose monitoring service notifies a first set of contacts when the opioid monitoring information.

An implantable pump includes a rigid housing with an oblate spheroid shape and having an inner chamber divided by a movable elastomeric membrane into a gas sub-chamber which is connectible through a drive line to an external pneumatic source, and a blood sub-chamber which is connectible through a graft assembly to an anatomical heart. The housing includes a blood port opening oriented at an angle and at the upper apex of the housing and connected to the blood sub-chamber, and a gas port opening to the gas sub-chamber that is situated at a lower apex of the housing. The pump is provided with a drive line that includes a gas conduit and a heart sensor, the drive line connectible to a drive system that is capable of delivering gas flow through the drive line gas conduit in response to signals driven by the heart sensor.

The inventive concepts disclosed and claimed herein are generally directed to an improved assisted walking device, such as a cane, walker or wheelchair, that includes an integrated oxygen concentrator housed within the assisted walking device. In some embodiments, for example, the improved assisted walking device includes a handle, a control pad, an elongated housing having an interior chamber, an oxygen concentrator, a leg member and a foot member. The oxygen concentrator detachably positioned within the interior chamber of the elongated housing and including an adsorption system configured to generate a flow of oxygen enriched gas, a compressor that includes a motor, a battery, a plurality of sieve beds configured to extract oxygen-enriched gas from ambient air, and a controller in communication with the control pad.

A flow of gases in a respiratory therapy system can be conditioned to achieve more consistent output from sensors configured to sense a characteristic of the flow. The flow can be mixed by imparting a tangential, rotary, helical, or swirling motion to the flow of gases. The mixing can occur upstream of the sensors. The flow can be segregated into smaller compartments to reduce turbulence in a region of the sensors.

Disclosed are methods and medical device systems for automated delivery of therapies for pain and determination of need for and safety of treatment. In one embodiment, such a medical device system may comprise a sensor configured to sense at least one body signal from a patient; and a medical device configured to receive a first sensed body signal from the sensor; determine a patient pain index based at least in part on said first sensed body signal; determine whether said patient pain index is above at least a first pain index threshold; determine a safety index based at least in part on a second sensed body signal; select a pain treatment regimen based on at least one of said safety index and or a determination that said pain index is above said first pain index threshold; and deliver said pain treatment regimen.

The present disclosure, in one embodiment, is a computer-implemented method for the detection of and intervention in traumatic nightmares. In one embodiment, a user wears a watch wirelessly connected to a phone. The watch may include an accelerometer, gyroscope, and heartrate monitor. The application may monitor these sensors and intervene with haptic feedback if the application detects a traumatic nightmare. In one embodiment, the application may include a monitoring module that collects data from the watch's accelerometer, gyroscope, and heartrate sensors. The application may then estimate and record stress levels based on these sensors. The application may also include an intervention module that responds to high stress levels with haptic feedback that increases in intensity of previous efforts to intervene were unsuccessful.

A bed system with multiple functions includes a frame structure; a plurality of platforms disposed on the frame structure; an adjustable assembly coupled with the frame structure and the plurality of platforms for operably adjusting one or more of the plurality of platforms in desired positions; a plurality of fans mounted onto openings in the plurality of platforms and adapted for operably providing air circulation in a surrounding space of the bed system, and an aromatherapy system attached onto the one or more platforms for producing desired fragrance in the surrounding space so as to promote health and well-being of a user. Each aromatherapy device is configured to produce a fragrance when said aromatherapy device is turned on, and one or more working modes. The fragrance is identical to or different from that produced by other aromatherapy device of the one or more aromatherapy devices.

Methods, pharmaceutical formulations and devices for the preventative treatment of incidental opioid overdose comprising the intramuscular or subcutaneous administration using an auto-injection device of a pharmaceutical formulation containing the opioid antagonist nalmefene as a prophylactic measure.
