A system for monitoring a health status of a person, includes a mobile terminal configured to display the status and in wireless communication with a first sensor attached to one leg of the person to acquire first information relating to a state of the one leg, and a second sensor attached to a part of a body of the person other than said one leg to acquire second information relating to a state of the part, and a server in communication with the terminal to acquire the first and second information from the sensors. The server is configured to compare the first and second information and determine a blood vessel state of said one leg based on its difference, and transmit to the terminal information indicating the blood vessel state. The mobile terminal is configured to update the status based on the information.

A wearable sensing band is presented that generally provides a non-intrusive way to measure a person's cardiovascular vital signs including pulse transit time and pulse wave velocity. The band includes a strap with one or more primary electrocardiography (ECG) electrodes which are in contact with a first portion of the user's body, one or more secondary ECG electrodes, and one or more pulse pressure wave arrival (PPWA) sensors. The primary and secondary ECG electrodes detect an ECG signal whenever the secondary ECG electrodes make electrical contact with the second portion of the user's body, and the PPWA sensors sense an arrival of a pulse pressure wave to the first portion of the user's body from the user's heart. The ECG signal and PPWA sensor(s) readings are used to compute at least one of a pulse transit time (PTT) or a pulse wave velocity (PWV) of the user.

Monitoring vital parameters of a wearer of a compression garment by analyzing a pressure signal waveform indicative of a fluid pressure in an inflatable and deflatable bladder of the compression garment. Analyzing the pressure signal waveform for an oscillating amplitude as a function of time and/or a representation of a pulse of the wearer provides an indication of blood pressure of the wearer.

One disclosed example device includes a flexible substrate; a first array of emitters embedded in the flexible substrate, the first array of emitters configured to emit first electromagnetic (EM) signals; a first array of detectors embedded in the flexible substrate, the first array of detectors configured to detect reflections of the first EM signals; a first scanning circuit coupled to the first array of emitters, the first scanning circuit configured to selectively activate individual emitters of the first array of emitters; and a first sensing circuit coupled to individual detectors of the first array of detectors, the first sensing circuit configured to receive a detection signal from at least one of the detectors of the first array of detectors.

Systems and methods for determining position and orientation of a bone of an anatomical feature are described. These include the use of a wearable holder configured to be mounted about an outer-skin surface of the anatomical feature, such that the anatomical feature and the bone are positioned in fixed relation with respect to the wearable holder when the wearable holder is mounted about the anatomical feature. Reference marker arrays are fixedly mounted to the wearable holder, each being positioned on the wearable holder to identify a landmark of the bone within the wearable holder when the wearable holder is mounted to the anatomical feature. The position and orientation of the reference markers are trackable to determine position and orientation of the wearable holder in a reference coordinate system, thereby enabling position and orientation of the landmarks on the bone to be determined.

Embodiments of the present disclosure provide an ECG monitoring device that comprises a housing cable comprising a plurality of signal cables positioned therein and a set of electrodes positioned along the housing cable. Each of the set of electrodes may contact a particular location of a user without requiring any muscular activity of the user when the ECG monitoring device is connected to the user. The ECG monitoring device may further comprise a computing device positioned along the housing cable and operatively coupled to each of the four or more electrodes via a respective signal cable of the plurality of signal cables. The computing device may comprise a memory and a processing device operatively coupled to the memory, the processing device to perform, using the four or more electrodes, an electrocardiogram (ECG) of the user.

An arrangement for producing a sample of body fluid from an opening created in a skin surface at a sampling site including a cartridge with a plurality of compartments and a plurality of sampling sites, and a detector assembly. Each sampling site includes a skin-penetration member having a first end configured to pierce the surface of the skin and an inner lumen in communication with the first end, a spring actuator operatively associated with the skin-penetration member, and a needle hub connecting the skin-penetration member and the spring actuator. The needle hub includes a reagent pad and the spring actuator is configured to drive the skin-penetration member to form the wound opening. Each compartment at least partially encloses the skin-penetration member, the spring actuator, and the needle hub of a respective sampling site.

A knee examination method includes the steps of situating a patient on a patient support adjacent a robotic knee testing apparatus, setting up the robotic knee testing apparatus, further setting up the leg of the patient relative to the robotic knee testing apparatus, and, after the steps of setting up and further setting up, examining knee laxity of a knee of the patient. The step of examining includes operating the robotic knee testing apparatus to manipulate the tibia positioning assembly.

The present invention is directed to a system for monitoring a physiological parameter of a cyclist, and methods of using the system. The system comprises a garment, a sensor, and a signal processor. The garment is configured to be worn by the cyclist. The sensor is fixedly coupled to the garment and configured to measure a signal representative of the physiological parameter during pedaling. The signal processor is operatively coupled to the sensor and configured to determine a diagnosis based on the measured signal. An alert is generated in response to the diagnosis substantially in real time.

A method to identify feature points associated with the heart valve movement, heart contraction or cardiac hemodynamics is revealed. The mechanocardiography (MCG) is a technology that makes use of vibrational waveforms acquired using at least one gravity sensor attached on one of the four heart valve auscultation sites on the body surface. The data of the electrocardiography (ECG) is recorded simultaneously with the MCG. The feature points are identified by comparing P, R and T points of synchronized ECG with the MCG spectrum. By the time sequences and amplitudes of the feature points, the method provides additional clinical information of cardiac cycle abnormalities for diagnosis.
