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.

In accordance with some non-limiting examples of the disclosed subject matter, an ingestible system configured to acquire physiological information from an interior of a subject is provided, comprising a substrate and at least one physiological sensor. The at least one “physiological sensor can be coupled to the substrate and configured to capture physiological data from at least one of an internal area or an orientation in a digestive tract of the subject. The system can include a controller coupled to the substrate and configured to receive the physiological data and prepare the physiological data for one of transmission from the subject or analysis of the physiological data. The substrate, including the at least one physiological sensor and the controller coupled thereto can be configured to self-orient within the digestive tract of the subject, during ingestion of the system by the subject.

System and methods for controlling healthcare devices and systems using voice commands are presented. In some aspects a listening device may receive voice command from a person. The voice command may be translated into human readable or machine readable text via a speech-to-text service. A control component may receive the text and send device-specific instructions to a medical device associated with a patient based on the translated voice command. In response to the instructions, the medical device may take an action on a patient. Some examples of actions taken may include setting an alarm limit on a monitor actively monitoring a patient and adjusting the amount of medication delivered by an infusion pump. Because these devices may be controlled using a voice command, in some cases, no physical or manual interaction is needed with the device. As such, multiple devices may be hands-free controlled from any location.

An example of a system for monitoring and treating respiratory distress in a patient may include signal inputs, a signal processing circuit, and a respiratory distress analyzer. The signal inputs may be configured to receive patient condition signals indicative of autonomic balance of the patient. The signal processing circuit may be configured to process the patient condition signals and to generate patient condition parameters indicative of the autonomic balance using the processed patient condition signals. The respiratory distress analyzer may be configured to determine a state of the respiratory distress using the patient condition parameters, and may include a parameter analysis circuit configured to analyze the autonomic balance of the patient and to determine the state of the respiratory distress using an outcome of the analysis.

Contactless operation of a medical device, such as a hemodialysis (HD) or peritoneal dialysis (PD) device, is provided via a mobile pointing apparatus and a receiving arrangement associated with the medical device. The mobile pointing apparatus includes a signal emitter for emitting an optical or electromagnetic signal, and the receiving arrangement associated with the medical device determines a pointing target of the mobile pointing apparatus relative to the medical device based on the signal emitted by the mobile pointing apparatus and triggers a function of the device based on the pointing target of the mobile pointing apparatus.

The EKG cord management system is a cable management system. The EKG cord management system is configured for use with the leads of an EKG machine. The EKG cord management system comprises a plurality of lead structures, a probe connector, and a housing. The EKG cord management system deploys the plurality of lead structures from the housing. The EKG cord management system retracts the plurality of lead structures into the housing. Each lead structure selected from the plurality of lead structures measures electrical activity in a human body. The probe connector electrically connects each of the plurality of lead structures to a machine known as an EKG machine.

A signal measurement circuit comprises: a sensor electrode layer connected via a sensor cable to a measurement amplifier circuit; an active shielding layer, which runs along a side of the sensor electrode layer that faces away from the patient; and a first insulating layer that runs between the sensor electrode layer and the active shielding layer. The sensor electrode layer and the active shielding layer are embodied to be electrically conductive.

Mandibular repositioning devices providing downward movement as well as forward movement of the mandible have a maxillary tooth covering having a driver flange protruding laterally outward on one or both sides thereof and have a mandibular tooth covering having a protrusive flange extending cranially therefrom positioned to have a posterior side engaged with the anterior side of each driver flange. The anterior side of each driver flange has a convex curvature. The posterior side of each protrusive flange has a concave-to-convex curvature positioned to move the convex portion thereof along the convex curvature of the driver flange when the mouth opens, which also moves the mandible forward. A plateau of a preselected height, which prevents disconnect between each protrusive flange and its respective driver flange relative to a fully open mouth measurement, is present between the base of the protrusive flange and the tooth covering.
