Connectors permits acoustic and digital stethoscope transmissions. Connectors include first and second pieces for the stethoscope chest piece and earpiece channels. The first piece has a moveable inner element with openings and includes a channel in line with the chest piece channel to provide an acoustic mode of functioning. The openings are collinear with the inner element channel and the extruded channels. The extruded channels and inner element channel may be arrayed in a line and have diameters that successively decrease. A transducer inside the inner element blocks sound from the first extruded channel, and a second transducer is inside the inner element on the other side of one of the openings. For an electronic mode of functioning, the first transducer is in line with the chest piece extruded channel and the second transducer is in line with the earpiece extruded channel. A switch may switch between the modes.

A Noninvasive Blood Pressure (NIBP) device, method, and system may employ one or more sensors configured to sense physiological changes associated with cardiovascular function and provide signals corresponding to the sensed physiological changes; one or more signal detectors to detect an ECG signal, a PPG signal, and a PCG signal from the signals provided by the one or more sensors; a computational system configured to derive signal features related to the detected signal waveforms; process the signal features to determine measurements of noninvasive blood pressure using one or more independent prediction models; and output a result of the determination.

There is provided a wheezing detection device, including: a wheezing determiner that performs processing of determining whether wheezing is included in the pulmonary sound of the subject, based on the signal of the pulmonary sound that is measured by a sound measurer after an instruction for starting wheezing detection processing is issued; and a controller that ends measurement of the signal of the pulmonary sound performed by the sound measurer and reports a result of the processing, in a case where an elapsed time period from a measurement start time point of the signal, which is firstly measured by the sound measurer after the instruction is issued, reaches a predetermined time period set in advance, or in a case where it is determined by the wheezing determiner that wheezing is included in the pulmonary sound of the subject.

A metallic diaphragm disk incorporating a piezoelectric material bonded thereto and operatively coupled to a base rim of a housing provides for closing an open-ended cavity at the first end of the housing. In one aspect, plastic film adhesively bonded to at least one of an outer rim of the housing or an outer-facing surface of the disk provides for receiving an adhesive acoustic interface material to provide for coupling the housing to the skin of a test subject. In another aspect, an outer-facing surface of a base portion of the housing provides for receiving an adhesive acoustic interface material to provide for coupling the housing to the skin of a test subject, at least one inertial mass is operatively coupled to a central portion of the metallic diaphragm disk, and the opening in the first end of the housing is closed with a cover.

Disclosed herein is a method and system for monitoring health risk of a user. The system receives a plurality of information related to clinical symptoms and cough sounds of a user and determines a symptom risk index and a cough risk index based on analysis of clinical symptoms and cough sounds. The system further receives body temperature and oxygen saturation information of the user and determines temperature risk index and oxygen saturation risk index based on the analysis of the received body temperature and oxygen saturation information. The system further determines a final risk index of the user based on the determined symptom risk index, cough risk index, temperature risk index and oxygen saturation risk index. The system provides a quick and easy solution to estimate or predict health risk information of the user.

A surgical sponge locator system for locating sponges after surgery for removal includes a base having a sponge portion and a housing portion. A plurality of surgical sponges is coupled within the base. Each surgical sponge has a signal receiver and a sound emitter in operational communication with the signal receiver. An antenna is coupled to the base and is in wireless communication with the signal receiver of each surgical sponge. A plurality of batteries is coupled within the base. A battery activator is coupled within the base. The battery activator selectively interrupts or allows operational communication between the plurality of batteries and the antenna. A sound activation lever is coupled to the housing portion and is in operational communication with the antenna.

A system for identifying targets wherein a projectile includes one or more sensors that gather sensor data about the environment and send the gathered data to a computing device. The computing device identifies the target by comparing the gathered sensor data to digital sensor signatures known to correspond to different types of objects. The system is also capable of identifying changes in a status of a target based on a change in the sensor data.

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.
