A jacket that includes a first portion, a second portion, and an interface. The interface is movably coupled to the first portion and the second portion. The first portion comprises multiple medical modules. The multiple medical modules include at least one medical sensor and a physiological signal conduit for transferring a physiological signal from an inner side of the first portion to an exterior side of the first portion. The first and second portions are configured to be detachably coupled to a mobile phone. When the jacket is at a closed position then the first portion, the second portion and the interface define an inner space that is configured to receive the mobile phone and the first and second portions contact opposite sides of the mobile phone. When the jacket is at an open position, then only one of the first and second portions contacts the mobile phone.

A physiological signal collection electrode comprises a signal collection pad having a skin contact portion, a signal output pad and an elongate bridging portion interconnecting the signal collection pad and the signal output pad. The signal collection pad, the signal output portion and the bridging portion are integrally molded of a flexible, conductive and resilient material. The width of the bridging portion is substantially smaller than that of the skin contact portion. A narrowed bridging portion operates to concentrate collected physiological signals collected by the skin contact portion before the signals are output to the signal output pad. An elongate bridging portion reduces skin covering area for better wearer comfort as well as providing better resiliency to the electrode when the bridging portion is extended.

Provided is an electrode including: a polarizable electrode layer; and a non-polarizable electrode layer laminated on the polarizable electrode layer. The non-polarizable electrode layer includes silver, silver chloride, and a corrosion inhibitor for the silver. The corrosion inhibitor is a polymer-based corrosion inhibitor.

A Wearable Cardioverter Defibrillator (WCD) system comprises an electrode assembly with a permeable ECG electrode and a moisture barrier. In some embodiments, the moisture barrier is configured to reduce drying out of the permeable ECG electrode to improve performance of the WCD system. In a further enhancement, some embodiments of the electrode assembly also include a pillow structure positioned on a non-skin-contacting surface of the electrode assembly to comfortably reduce movement artifact or noise in the received ECG signal.

A pulse sensor is capable of measuring a pulse rate of a wearer at a peripheral artery. In an embodiment, the pulse sensor includes a magnet supported to move responsive to an arterial pulse and a magnetometer configured to detect changes in a magnetic field produced by the magnet. The magnet may include a plurality of ferromagnetic particles disposed in or on a flexible substrate configured to be held adjacent to human skin subject to arterial palpation and a magnetic sensor configured to sense movement of the ferromagnetic particles. A system and method may measure hydration includes using a pulse sensor to measure pulse rate and modulation. The wearer is prompted when the pulse rate and pulse modulation indicate a response to dehydration of the wearer.

The present disclosure provides a noise reduction device. The noise reduction device may include a noise receiving component, a noise reduction component, a processing component, and a housing. The noise receiving component may be configured to receive acoustic noise information of a scanning environment where a medical device is located. The processing component may be configured to control the noise reduction component to generate sound information matching the acoustic noise information received by the noise receiving component. The housing may be configured to support the noise receiving component and the noise reduction component.

A biological sensor includes a sensor body for acquiring biological information; an electrode connected to the sensor body; a first layer member configured to store the sensor body, a first adhesive layer being disposed on one surface of the first layer member facing the electrode; and a second layer member being stuck onto the one surface of the first layer member, and having a shape for covering the sensor body and exposing the electrode, a second adhesive layer being disposed on a surface of the second layer member opposite to the first layer member. A sticking surface onto a living body is formed by the first layer member and the second layer member.

A patch-type biomedical device cover that includes a cover film, a first adhesive member, and a second adhesive member. The cover film includes an upper cover film and a lower cover film and is configured to be folded into a bag when in use so as to be able to accommodate a temperature sensor therein. The first adhesive member is on an outside surface of the lower cover film. The second adhesive member is on an inside surface of the lower cover film. The second adhesive member is configured to adhere the temperature sensor to the lower cover film and to adhere an edge portion of the upper cover film to an edge portion of the lower cover film so as to close the upper cover film and the lower cover film to form the bag.

A body electrode unit includes a body electrode and a release sheet to which the body electrode is attached. The body electrode includes a first electrode configured to stimulate a muscle of a body, a second electrode, and a third electrode. The second electrode and the third electrode are configured to detect a physiological signal from the muscle that is stimulated by the first electrode. The body electrode also includes a first connection portion arranged between the first electrode and the second electrode, and a second connection portion arranged between the third electrode and one of the first electrode and the second electrode. The first connection portion has at least one first direction changing part configured to change a direction in which the first connection portion extends, such that at least one of a distance and an angle between the first electrode and the second electrode is adjustable.

The disclosure relates to a radio-based physiological acquisition system for an RF-shielded room comprising a peripheral acquisition unit with a peripheral transmitter, a peripheral control unit, and a door sensor unit. The door sensor unit is configured to determine an opening status of a door in an RF shield around the RF-shielded room. The peripheral acquisition unit is configured to switch off the peripheral transmitter depending on the opening status of the door, e.g. when the door is open.
