An apparatus for calming a baby in an interior of a vehicle has a heartbeat sensor device (11, 12, 13) configured to capture a heartbeat input signal that depends on the heartbeat of an occupant in an interior (18) of a vehicle (10). A heartbeat signal processing device (14) is configured to produce a heartbeat output signal that depends on the heartbeat input signal. A calming signal output device (15, 16, 17) is configured to output a calming signal that depends on the heartbeat output signal and that is perceivable by a baby in the interior (19) of the vehicle (10). The apparatus is to configured to output the calming signal, at least intermittently, directly during the capture of the heartbeat input signal.

A hollow puncture needle includes: a needle body portion; a needle distal end portion that extends from the needle body portion in a distal direction and that includes a blade surface that is inclined with respect to an axis of the puncture needle; and an ultrasonic wave reflecting structure including at least one reflecting portion having a concave or hole shape that opens on an inner peripheral surface of the needle distal end portion. An inner surface of the reflecting portion includes a pair of inclined surfaces that face each other, wherein a distance between the inclined surfaces becomes smaller in a direction towards an outer peripheral surface side of the needle distal end portion. The inclined surfaces is parallel to the axis of the puncture needle.

A puncture device guide includes a body member configured to fixedly attach to an ultrasound probe, a slide member slidingly received within the body member; and a cradle member slidingly received within the slide member and longitudinally fixed relative to the body member. The cradle member is configured to receive a puncture device therein. Longitudinal movement of the slide member causes radial movement of the cradle member relative to the body member.

Methods and apparatus provide controlled operations in an oxygen concentrator (100) such as by adjusting valve opening time to regulate amount of oxygen enriched air released to a user. The apparatus may generate, with a sensor configured to sense pressure at a location associated with accumulation of enriched air produced by the concentrator, a signal representing measured pressure of the accumulated enriched air. The apparatus may generate, with a sensor, a signal indicative of respiration of a user of the concentrator. The apparatus may include a controller configured to receive the measured pressure and respiration signals. The controller may control, responsive to the respiration indication and according to a target duration, actuation of a valve adapted to release a bolus of accumulated oxygen enriched air. The controller may dynamically determine the target duration during the release of the bolus according to a function of a value of the measured pressure.

A workstation for processing particles entrained in a fluid includes a consumable portion and a reusable portion. The consumable portion is mounted to the reusable portion to form a fluid chamber in which an acoustic wave can be generated. The consumable portion implements a closed, isolated fluid environment that is managed using components of the reusable portion, such as valves, sensors and pumps. The workstation can be operated to retain particles from the fluid via the acoustic wave and provide a new fluid media to the retained particles. Following processing, the consumable portion can be removed and discarded.

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.

The invention relates to a detection apparatus and a method for detecting and manipulating a blood vessel under the skin of part of the body of a patient, which comprises a treatment chamber for accommodating the body part, a data processing control device, a vascular structure measuring device for detecting the position and/or dimensions of vascular structure data of the blood vessel in the treatment chamber by measurement, a vascular manipulation device for changing the position and/or dimension of the blood vessel, wherein the control device is designed to control the vascular manipulation device as a function of the vascular structure data.

A fluid control device includes an interface to a remote fluid monitoring sensor that detects fluid flow in a patient. In some embodiments, a processor within the fluid delivery device is programmed to adjust the delivery or withdrawal of fluids based on the fluid flow signals provided by the sensor. In some embodiments, the fluid control device can display and/or record fluid flow signals thereby acting as a hemodynamic monitor.

A breathing assistance apparatus is configured with features that improve serviceability of the apparatus. The apparatus can include animations to provide instruction regarding correcting easily-identified fault conditions and to provide instruction regarding routine maintenance routines. The apparatus also can be configured with top level control menus that are obscured in a manner to limit manipulation of the top level control elements by unauthorized users.

Disclosed are methods, systems, and devices for providing a personalized humidification level. A control system receives, from a first sensor, one or more environmental parameters regarding conditions of the environment. The control system receives, from a second sensor, one or more physiological parameters associated with a user within the environment. The control system determines an action associated with a desired change in the humidity within the environment based, at least in part, on the one or more environmental parameters and the one or more physiological parameters. The control system causes, at least in part, a performance of the action associated with the change in the humidity in the environment based, at least in part, on moisture outputted by a humidifier module. The methods and devices perform the same functionality as the control system.
