Biosignals include EKG and PPG, from which a determination of pulse transit time can be made.

Various embodiments are described herein for a device, system, and method for identifying a location of an ingestible device within a gastrointestinal tract of a body. In some embodiments, the ingestible device includes a sensing unit with an axial optical sensing sub-unit located proximal to at least one end of the device, and a radial optical sensing sub-unit located proximal to a radial wall of the device, and may autonomously identify a location within the gastrointestinal tract. In some embodiments, the ingestible device includes optical illumination sources and detectors that operate at a plurality of different wavelengths, and may discern regions of a gastrointestinal tract by using the reflection properties of organ tissue and occasional particulates. In some embodiments, the ingestible device may sample fluid or release medicament based on a detected device location.

Insertable imaging devices and use methods thereof in minimally invasive medical procedures. Some insertable imaging devices are introduced and removed from an access port without disturbing or risking damage to internal tissue. Some insertable imaging devices are integrated with an access port, thereby allowing imaging of internal tissues within a vicinity of the access port, while enabling manipulation of surgical tools in the surgical field of interest. Some insertable imaging devices are integrated into an imaging sleeve that is insertable into an access port. Some insertable imaging devices perform imaging within an access port, wherein the imaging is based on one or more imaging modalities, including, but are not limited to, magnetic resonance imaging, ultrasound, optical imaging, such as hyperspectral imaging and optical coherence tomography, and electrical conductive measurements.

Modular, miniaturized cardiovascular sensors, systems, methods, and wearable devices for the non-obtrusive evaluation, monitoring, and high-fidelity mapping of cardiac mechanical and electromechanical forces and central arterial blood pressure are presented herein. The sensor manufacturing process is also presented. Using accelerometers, the sensors register body-surface (preferably torso-surface) movements and vibrations generated by cardiac forces. The sensors may contain single-use or reusable components, which may be exchanged to fit different body sizes, shapes, and anatomical locations; they may be incorporated into clothing, bands, straps, and other wearable arrangements. The invention presents a practical, noninvasive solution for electromechanical mapping of the heart, which is useful for a wide range of healthcare applications, including the remote monitoring of heart failure status and the guidance of cardiac resynchronization therapy. Exercise and cardiovascular fitness tracking applications are also presented.

A carrier assembly and related sterile kits are disclosed. The carrier assembly is configured to be used with a sensor assembly for determining a characteristic of a human body. The carrier assembly comprises a frame member comprising a sidewall defining a central opening configured to receive at least a portion of the sensor assembly and laterally extending wing members hingedly attached at a proximal end thereof to the sidewall of the frame member. The laterally extending wing members each comprise a cavity proximate a distal end thereof and configured to receive a magnet. Related kits and systems are also disclosed.

Embodiments of a wearable device are provided. The wearable device comprises a reusable component and a disposable component. The disposable component comprises a patient engagement substrate comprising adhesive on a bottom side, an electrode on the bottom side, a disposable component electrical connector, and a disposable component mechanical connector. The reusable component comprises a plurality of sealed housings mechanically coupled to each other and movable with respect to each other, each of the plurality of housings containing one or more of a capacitor and a controller, a reusable component mechanical connector adapted to removably connect to the disposable component mechanical connector, and a reusable component electrical connector adapted to removably connect to the disposable component electrical connector. The device can comprise a cardiopulmonary physiologic monitor or an automatic external defibrillator, among other types of devices.

An X-ray device has a detector which is arranged on a mobile unit and is assigned to a first positioning unit. An X-ray source is arranged on an arcuate second positioning unit. The positioning of the first and second positioning units can be matched to one another in the course of their movements. The first positioning unit has at least one articulated arm and the second positioning unit has a first and a second arc-shaped positioning element. The first and second positioning units are arranged separately from one another on a movable unit.

Upon using a stethoscope, there is a problem that it had been needed to interrupt work and mount the stethoscope using both hands, resulting in poor work efficiency. Also, when it is needed to repeatedly mount and unmount the stethoscope for such as a group examination, for example, it had been necessary to continuously carry out an operation of expanding ear tubes many times, which is complicated. Thus the present invention provides an attachment for a stethoscope comprising a mounting part which can be mounted to both of ear tubes, and a manipulating part for manipulating the mounting part, the manipulating part and the mounting part being connected through a rotatable fulcrum, so that the mounting part may be opened and closed by opening and closing operation of the manipulating part.

A method for performing an examination includes at least one magnetic resonance-based and at least one further examination step. An examination object is positioned during the entire examination on an upper side of a transfer plate that is positioned on an object table during the magnetic resonance-based examination. At least one coil holder that includes at least one local coil or by which at least one coil device is supported is used during the magnetic resonance-based examination step. The coil holder is arranged on the examination object during the magnetic resonance-based examination step exclusively. The coil holder is supported during the magnetic resonance-based examination steps by at least one mounting, into which a supporting section of the coil holder engages and/or which engages into the supporting section of the coil holder.

The present disclosure describes a vital sign monitoring device configured for monitoring one or more patient vital signs. The device includes a disposable patch assembly attachable to a reusable electronics package. The patch assembly includes an adhesive layer for adhering to a patient's skin. A vital sign sensor is embedded within the adhesive layer. A flexible circuit connects to the sensor on an upper side of the adhesive layer, and provides electrical contact between the sensor and the electronics package. The electronics package includes a battery and microcontroller for powering and controlling the sensor.
