An apparatus for estimating bio-information according to an embodiment includes: a sensor that measures a pulse wave signal from an object and contact pressure of the object; and a processor that obtains an oscillometric envelope based on an amplitude of the pulse wave signal and the contact pressure, and estimates bio-information based on a center of mass of a phase of contact pressure of the obtained oscillometric envelope.

A pressure sensing mat having first and second conductive layers and an insulative layer. The first conductive layer defines a first aperture and includes first spaced apart conductive regions and first non-conductive regions therebetween. The first spaced apart conductive regions and non-conductive regions extends in a first direction. The second conductive layer defines a second aperture and includes second spaced apart conductive regions and second non-conductive regions therebetween. The second spaced apart conductive regions and the second non-conductive regions extend in a second direction different than the first direction. The insulative layer is between the first and second conductive layers and defines a third aperture. The first, second, and third apertures are aligned with each other such that the first, second, and third apertures form a vent through the first and second conductive layers and the insulative layer.

Devices, methods, and systems are provided for occluding a collateral flow channel between a target lung compartment and an adjacent lung compartment. A video-assisted thoracoscopic device is inserted into a thoracic cavity of a patient and positioned at a fissure between a target lung compartment and an adjacent lung compartment. A collateral flow channel between the target lung compartment and the adjacent lung compartment is then identified using the video-assisted thoracoscopic device and an agent is injected into the collateral flow channel, thereby reducing the collateral flow channel.

The present disclosure relates to technology for estimating bio-information by using a foldable electronic device. The foldable electronic device includes a main body part, having a first main body and a second main body, configured to fold along a folding line; a first sensor provided on the first main body, and configured to obtain a contact image of an object of a user; a second sensor provided on the first main body, and configured to measure a degree of folding of the main body part; and a processor configured to estimate bio-information of the user, based on the contact image of the object and the degree of folding.

A craniofacial implant includes a craniofacial implant body and a passive pressure sensor. The craniofacial implant body permits measurement of the passive pressure sensor via externally applied stimuli passing through the craniofacial implant body.

A method and system are disclosed for use in monitoring/screening/diagnosing sleep or wake state of a subject or patient. The method generally includes monitoring the patient's activity during one or more sleep sessions comprising a plurality of intervals known as epochs. The sleep/wake state of the subject is determined during each epoch of the session using actigraphy data obtained during the monitoring session. The actigraphy data provides information about the activity of a patient during an epoch. The sleep or wake state is determined based on a ratio of the activity count during an epoch to the activity count during a preceding epoch. If the ratio is greater than a first activity threshold, then a “wake” indication may be provided by, for example, the system. Alternatively, or additionally, a “wake” indication may be determined if the activity count during the epoch is greater than a threshold.

A system for monitoring medical conditions including pressure ulcers, pressure-induced ischemia and related medical conditions comprises at least one sensor adapted to detect one or more patient characteristic including at least position, orientation, temperature, acceleration, moisture, resistance, stress, heart rate, respiration rate, and blood oxygenation, a host for processing the data received from the sensors together with historical patient data to develop an assessment of patient condition and suggested course of treatment, including either suspending or adjusting turn schedule based on various types of patient movement. Compliance with Head-of-Bed protocols can also be performed based on actual patient position instead of being inferred from bed elevation angle. The sensor can include bi-axial or tri-axial accelerometers, as well as resistive, inductive, capacitive, magnetic and other sensing devices, depending on whether the sensor is located on the patient or the support surface, and for what purpose.

The present application discloses devices and methods for monitoring the performance of a hemostasis device during a hemostatic procedure.
