A patchable biosensor includes a substrate extending in a longitudinal direction and being stretchable for being patched to a surface of a living body and an electronic component disposed on a one-side surface in a thickness direction of the substrate and extending in the longitudinal direction. The longitudinal direction of the electronic component crosses the longitudinal direction of the substrate.

The disclosed sensor assembly may be used in a patient monitoring system to monitor one or more physiological parameters of a patient. The sensor assembly may include a substrate and one or more electrodes, which may include a lattice structure to limit a contact area between the one or more electrodes and skin of the patient. The sensor assembly may include connectors or connector assemblies that facilitate connection between the one or more electrodes and a data acquisition unit. The sensor assembly may be especially useful for patients with sensitive skin, such as infants in a neonatal intensive care unit (NICU).

This biomedical electrode has conductive gels 11, 11, retaining members 12, 12 to retain the conductive gels 11, 11, and an adhesive surface 31a, and comprises a sheet-shaped adhesive member 30 to adhere the conductive gels 11, 11 to a living body surface S via the retaining members 12, 12, and further, the adhesive member 30 is formed in an enough size to cover substantially all regions of the retaining members 12, 12, and is configured to have liquid through holes 30b to 30b, 30c, 30c to discharge sweat which is accumulated in internal spaces R, R formed between the living body surface S and the retaining members 12, 12.

A physiological monitoring system includes an electrocardiogram (ECG) module and a main module connected by a first communication connection that is wireless. The main module receives the first physiological data from the ECG module using the first communication connection. The main module stores the physiological data and transmits alerts using both wireless or wired communication connections. The ECG module can identify one or more abnormal conditions of the patient, and transmit in real-time results of the analysis to the main module using the first communication connection and/or transmit alerts or alarms directly to the patient's skin. Additionally, a detachable pre-cordial electrode array can be added that includes a second plurality of electrodes worn in a precordial location of the patient to gather second physiological data and transmits the second physiological data to the ECG module or the main module.

A system for determining a location of a structure within a patients vasculature includes three or more pads adhered to the patients torso in a predetermined pad pattern. Each pad generates a pad electrical signal. A stylet has longitudinally spaced proximal and distal stylet ends, with at least one stylet electrode located proximate the distal stylet end. The stylet electrode receives the pad electrical signals and responsively generates a stylet electrical signal. A signal processor is operatively coupled for signal exchange with the stylet and to each of the pads via a selective electrical coupling. The signal processor compares the stylet electrical signal and at least two pad electrical signals to triangulate a position of the stylet electrode relative to each of the pads and responsively produce a triangulated position. The triangulated position is indicative of a position of the stylet electrode within the patients vasculature.

An electrode configured to provide electrical contact with skin of a subject is provided. The electrode includes an electrode body configured to be removably coupled with the skin of the subject and to receive electrical signals from and/or transmit electrical signals to the skin of the subject, and an electrical coupling that facilitates coupling the electrode to an external computing system. The electrode body includes a conductive silicone material configured to enable uptake or diffusion of moisture from the skin of the subject over which the electrode body is disposed; and a detergent configured to facilitate a flow of ions through the conductive silicone material.

Long-term electrocardiographic and physiological monitoring over a period lasting up to several years in duration can be provided through a continuously-recording subcutaneous insertable cardiac monitor (ICM). The sensing circuitry and the physical layout of the electrodes are specifically optimized to capture electrical signals from the propagation of low amplitude, relatively low frequency content cardiac action potentials, particularly the P-waves that are generated during atrial activation. In general, the ICM is intended to be implanted centrally and positioned axially and slightly to either the left or right of the sternal midline in the parasternal region of the chest. Additionally, the ICM includes an ECG sensing circuit that measures raw cutaneous electrical signals and performs signal processing prior to outputting the processed signals for sampling and storage.

A system and method for facilitating a cardiac rhythm disorder diagnosis with the aid of a digital computer is provided. A plurality of R-wave peaks are identified in a set of ECG data and a difference between recording times of successive pairs of the R-wave peaks are calculated as R-R intervals. A heart rate associated with each time difference is determined. An R-R interval plot of the ECG data is formed. The R-R intervals are plotted along an x-axis of the R-R interval plot and the heart rates associated with the R-R intervals are plotted along a y-axis of the R-R interval plot. A diagnostic composite plot is generated, including the R-R interval plot, a near field view of a portion of the ECG data, and an intermediate field view of a different portion of the ECG data for diagnosis of a cardiac event.

An electrode padset and a method of using the electrode padset are disclosed herein. The electrode padset is a single unit, consisting of multiple patient-contacting conductive pads arranged on a single piece of material. The padset is comprised of a plurality of conductive pads, at least one conductive pad adapted to emit an electrical signal and at least one other conductive pad adapted to receive an electrical signal, and an electrically conductive material coupling the conductive pads.
