Fault detection and diagnostics for a microneedle array based continuous analyte monitoring device are provided. The electrochemical sensors, including the electrodes of the analyte monitoring device configured for measuring one or more target analytes, may experience various faults during use of the analyte monitoring device. By modeling the sensors as an electrical network, measurements of the electrical network may be correlated with operational parameters of the sensor. The voltage at the counter electrode provides an indication of the resistance or impedance between the working electrode and the counter electrode and is used to identify the occurrence of faults occurring at the continuous analyte monitoring device.

The present invention includes a pressing cuff for compressing a measurement target site. A sensing cuff containing a pressure transmission fluid is provided on an inner circumferential side of the pressing cuff. A pressure at a rising start point and a pressure at a peak point indicated by a pressure pulse wave for each beat are obtained by subtracting a direct current component of data representing a pressure of the pressing cuff from data representing a pressure of the sensing cuff in the process of depressurization. A first time point at which the pressure at the peak point for each beat transitions between a zero level and a positive value is obtained. A second time point at which the pressure at the rising start point for each beat transitions between the zero level and the positive value is obtained.

An anchor including shape memory metals, shape memory polymers or a combination thereof. The anchor has surgical and nonsurgical uses.

A wearable device for administering an electroretinography examination to a wearer can have a housing that defines a first and a second compartment. Each of the first and second compartments can comprise: a stimulation light source, a focal light source, an active electrode that is configured to engage skin of the wearer, and a reference electrode that is spaced from the active electrode and configured to engage skin of the wearer. A processor can be communicatively coupled to the stimulation light source, the active electrode, and the reference electrode of each of the first and second compartments of the housing. A memory can be in communication with the processor. The device can perform a method comprising: causing the stimulation light source of the first compartment to flash; and storing a signal from the active electrode of the first compartment. The housing can further comprise a ground electrode.

A system comprising: a first module comprising a first sensor, capable of performing biometric sensing at a first location on a patient; and a second module comprising a second sensor, capable of performing biometric sensing at a second location on the patient. The first module comprises a transmitter for transmitting first sensor data, the first sensor data comprising sensing information obtained by the first sensor.

An example device for detecting one or more parameters of a cardiac signal is disclosed herein. The device includes one or more electrodes and sensing circuitry configured to sense a cardiac signal via the one or more electrodes. The device further includes processing circuitry configured to determine an R-wave of the cardiac signal and determine whether the R-wave is noisy. Based on the R-wave being noisy, the processing circuitry is configured to determine whether the cardiac signal around a determined T-wave is noisy. Based on the cardiac signal around the determined T-wave not being noisy, the processing circuitry is configured to determine a QT interval or a corrected QT interval based on the determined T-wave and the determined R-wave.

Disclosed is a sensor pad which may be used for medical/health care applications. The sensor pad may comprise an outer cover and a sensor pad body, the outer cover comprising a first surface layer and a second surface layer which form an accommodating cavity configured to receive sensor pad body, the first surface layer further comprising a non-slip layer, wherein both the first and second surface layers are formed from at least one biodegradable material for reduced environmental pollution.

A vascular imaging device has a casing having a first casing portion (4) and a second casing portion (5). The first casing portion and the second casing portion together define a gap (10) therebetween for receiving an auricle of a subject. The device also includes light source (12) and an image sensor (20) both mounted on the casing. The light source is arranged to transmit light to illuminate an auricle placed within the gap. The image sensor is arranged to detect light transmitted by the light source and output image data representative of the light received at the image sensor.

An ophthalmologic information processing system for selecting a subject at risk of glaucoma as a candidate includes: an information acquisition unit that acquires measurement information of an eye of the subject measured by an ophthalmologic apparatus; and a determination unit that determines whether the subject is a candidate at risk of glaucoma based on an anterior chamber depth of the subject included in the measurement information acquired by the information acquisition unit.

A device for collecting blood from a mammalian subject without using spontaneous capillary blood flow, the device including a collection cup subassembly having a cantilevered, concave slide for transporting blood down and away from a blood sampling location; a mid-body subassembly couplable to the collection cup assembly and including a housing having a proximal end and a distal end and defining a plenum space; and a plunger subassembly having a first end and a second end and including a plunger formed at the second end and one or more lancet elements attached to the plunger. Advantageously, the plunger and lancet elements are structured and arranged to translate through the mid-body subassembly and the collection cup subassembly to the blood sampling location.
