A wearable health management system includes a flexible member configured to be worn on an affected area by a patient. At least one actuator is operably coupled to the flexible member. The at least one actuator is configured to be adjusted between a deployed state and a non-deployed state. At least one of a photoplethysmogram sensor and a bioimpedance sensor is coupled to the flexible member to obtain one or more health metrics from the patient. A controller is in communication with the at least one actuator. The controller is configured to adjust the at least one actuator to the deployed state to provide a selected pressure to the affected area.

The present invention relates to a blood flow restriction system, comprising: a tourniquet cuff (C) or band to be placed around a limb, proximally to a target muscle, tightened so as to apply a specific pressure during a blood flow restriction exercise regimen; and measuring and monitoring means (M, P) made and arranged to measure and monitor microvascular blood flow within the target muscle, to guide safety and performance parameters of the blood flow restriction exercise regimen according to hemodynamic criteria. The present invention also relates to a method adapted to use the system of the invention, and to a computer program with code instructions to implement the steps of the method of the invention.

A device for delivering chest compressions for performing cardiopulmonary resuscitation includes a compression assembly and chest contact pad that can be positioned over the thorax of a patient experiencing a cardiac arrest. The compression assembly is supported by a frame and one or more positioning mechanisms for moving the compression assembly relative to the patient's left ventricle. A controller causes the compression assembly to deliver a plurality of chest compressions to the patient. A blood flow monitor, such as a Doppler ultrasound monitor, is coupled with the patient's femoral or carotid artery to monitor the flow of arterial blood when chest compressions are delivered and to communicate blood flow parameter information to the controller. The controller causes the positioning mechanism to move the location where the compressions are delivered to optimize the blood flow parameters. The controller monitors the blood flow parameters to determine the occurrence of a return to spontaneous circulation (ROSC). When ROSC is detected, the controller causes the compression assembly to cease chest compressions.

Systems, devices and methods for providing active and/or passive compression therapy to a body part can include a compression device worn over a compression stocking. The compression device can have a pulley based drive train that is driven by a motor to tighten and loosen compression elements, such as compression straps, in a precise, rapid, and balanced manner. Sensors can be used in the compression device and/or compression stockings to provide feedback to modulate the compression treatment parameters.

Systems and method for providing chest compressions to a patient during cardiopulmonary resuscitation may comprise at least one ECG sensor configured to obtain ECG signals, an automated chest compressor configured to provide chest compressions and at least one processor, memory and associated circuitry of a medical device communicatively coupled with the at least one ECG sensor and the automated chest compressor. The at least one processor may be configured to receive and analyze the ECG signals, determine, based on the analysis, whether the patient is in a condition of unconscious hypotension with organized ECG, analyze, in response to a determination that the patient is in the condition of unconscious hypotension with organized ECG, the received ECG signals to detect a QRS complex, and generate an output to apply a chest compression at a predetermined time relative to the detected QRS complex.

An apparatus for at least one of diagnosing or treating an eye condition can include a goggle enclosure, sized and shaped to be seated on an eye socket of an eye to provide one or more cavities within the enclosure that extend about an entire exposed anterior portion of the eye, a pump, in fluidic communication with the one or more cavities to apply a fluid pressure to the one or more cavities, the pump configured to adjust a fluid pressure within the one or more cavities of the goggle enclosure, and a control circuit, including a data interface to receive data directly or indirectly indicating at least one of an intraorbital pressure, ICP, IOP, or a relationship between ICP and IOP, and based on processing the received data as a feedback control variable, controlling the pump to adjust the fluid pressure within the one or more cavities, the controlling including using further monitoring of the received data to control the pump.

Non-invasive blood pressure (NIBP) systems and methods are disclosed that measure a blood pressure, and in some examples a beat-to-beat blood pressure, of a patient without restricting blood flow. The NIBP systems determine an efficacy of administered cardiopulmonary resuscitation (CPR) to the patient based on the measured blood pressure and are able to optionally output the CPR efficacy or generate user prompts based on the CPR efficacy. Further, the disclosed NIBP systems can generate user instructions to administer further treatment to the patient based on the CPR efficacy.

An actuator delivers mechanical vibrations to the body of a subject. The actuator includes a piezoelectric element, electrodes in electrical communication with an electrical source and the piezoelectric element to drive the piezoelectric element, a polymeric protective layer encapsulating the piezoelectric element and part of the electrodes, and an enclosure attached to the protective layer. The actuator includes a space between the protective layer and the enclosure allowing desired modes of vibration to develop across a surface of the protective layer that encapsulated the piezoelectric element. The actuator can include a skin attachment article that has a mounting pad for attaching to the skin of the subject and for attaching the actuator. The skin attachment article has a cover that overlies the actuator and the mounting pad when the article is attached to the skin of the subject.

In a stimulus method, a stimulus applying apparatus is attached to an area selected from a group of specific parts of a body surface by an acupuncture needle(s) or heating etc. thereby releasing the stress, and a stress-free medical treatment method based on the stimulus method.
