Described herein is a video laryngoscope designed for easy and safe operation comprising an apparatus body, a laryngoscope camera arm unit, and an associated laryngoscope blade releasably attached to the laryngoscope camera arm unit. The laryngoscope camera arm unit is angularly adjustable by use of a rotary linkage member connected to a distal end of the apparatus body. A communication unit is connected to a linkage device at a proximal end of the apparatus body. A light source and a video camera are located on the laryngoscope camera arm unit. The laryngoscope blade has at least two internal fluidic channels for delivering fluid to oral cavity regions of a patient and providing suction of bodily fluids from the patient.

Provided is a virtual reality (VR) device, system and framework for generating VR continuum experience choreographed to a physical procedure incorporating at least one procedural action associated with a physical sensation and potentially inducing an anxiety or pain response. The VR continuum experience can modify perceptions of pain and anxiety associated with the procedure. The virtual reality device is configured to allow device control via a device user interface accessible to an operator other than the wearer (i.e. a medical practitioner), to allow the operator to control device calibration and virtual reality (VR) experience start while the apparatus is worn by the wearer, and to provide one or more VR experiences each associated with a physical procedure.

A dialysis system, comprising: a dialysis machine; a voice recognition component configured to identify a voice command in audio information received by a microphone of the dialysis system; an authentication component configured to determine a source of the voice command; and a processor configured to perform a function determined based on the voice command.

A personal vapor inhaling unit is disclosed. An electronic flameless vapor inhaler unit that may simulate a cigarette has a cavity that receives a cartridge in the distal end of the inhaler unit. The cartridge brings a substance to be vaporized in contact with a wick. When the unit is activated, and the user provides suction, the substance to be vaporized is drawn out of the cartridge, through the wick, and is atomized by the wick into a cavity containing a heating element. The heating element vaporizes the atomized substance. The vapors then continue to be pulled by the user through a mouthpiece and mouthpiece cover where they may be inhaled.

A vaporizing article, comprises a vaporizer drive circuit; one or more memories configured to store a percentage of at least one constituent in an inhalation media, one or more compensation values for at least one compensation category for the at least one constituent, and instructions; and a control circuit comprising a processor coupled with the one or more memories configured to run the instructions, the instructions configured to cause the processor to: receive a dose target for a constituent; determine whether to perform compensation for an inhalation media dose in order to ensure the dose target is met; when compensation is to be performed, determine the properly compensated inhalation media dose based on an associated compensation value for the constituent; and control the vaporizer drive circuit so as to dispense a compensated dose of the inhalation media.

Systems, computer-implemented methods and/or computer program products that facilitate real-time response to defined symptoms are provided. In one embodiment, a computer-implemented method comprises: monitoring, by a system operatively coupled to a processor, a state of an entity; detecting, by the system, defined symptoms of the entity by analyzing the state of the entity; and transmitting, by the system, a signal that causes audio response or a haptic response to be provided to the entity, wherein transmission of the signal that causes the audio response or the haptic response is based on detection of the defined symptoms.

A wearable breast pump system is provided. The wearable breast pump system can include a housing having a pump, a breast flange, and a milk container. The pump can form part of a closed loop system that drives a separate, deformable diaphragm to generate negative air pressure. The diaphragm can be removably mounted on a breast shield.

Apparatus and methods are described including a blood pump that includes a catheter, a first impeller disposed on the catheter, and a second impeller disposed on the catheter, proximally to the first impeller. A control unit drives the first and second impellers to pump blood of a subject, by driving the first and second impellers to rotate. The blood pumps is configured such that (a) the first and second impellers are shaped differently from each other when the first and second impellers are in non-radially-constrained configurations, (b) the first and second impellers are sized differently from each other when the first and second impellers are in non-radially-constrained configurations, and/or (c) the first and second impellers are driven by the control unit to rotate under respective rotation conditions that are different from each other. Other applications are also described.

Systems and methods for providing resuscitative chest compressions to a chest of a patient are described. One exemplary system may include a chest compressor for administering chest compressions to the patient, one or more sensors for measuring and generating electrocardiogram (ECG) signals of the patient's heart. The system may include at least one processor coupled to memory and configured to receive and analyze the signals corresponding to the ECG, determine an intrinsic heart rate, identify at least one ECG waveform within the ECG signals, select a chest compression protocol from at least three or at least four predetermined chest compression protocols for administration to the patient based at least in part on the intrinsic heart rate of the patient, and control the chest compressor based on the selected chest compression protocol.

Systems and methods for generating sounds in a vehicle or other location are presented. In one example, a single user input may be a basis for adjusting a sound level and a frequency of occurrence of a sound that is stored in controller memory and that is output via one or more speakers.
