Patent number: 9737269Abstract: A patient communicator device provides the ability for non-verbal communication between a patient and medical personnel. The device includes a handgrip module that is held by the patient and a display unit for use by the medical personnel, with a communication link coupling the two components together. The handgrip module is formed of a deformable material and encases a power source (i.e., battery) and a pressure-activated switch. The patient squeezes the handgrip module to close the switch and transmit a signal to the display unit.

Patent number: 9041551Abstract: A disclosed telemetry system comprises an Nth number of telemetry devices and an equal number of standard disposable circular electrode patches. A body of each telemetry device in the system includes a female snap receptor configured to attach to a single male snap post of an electrode patch. A wireless transmitter module is disposed immediately around and in direct connection with each female snap receptor. Each wireless transmitter module transmits a signal from the respective female snap receptor to a receiver. A wireless receiver module is configured to receive and to process an Nth number of transmitted signals from the Nth number of telemetry devices into an Nth?1 number of signals where the number of signals is greater than zero. There are Nth?1 number of signals because at least one of the Nth telemetry devices is configured as a ground reference for the rest of the Nth telemetry devices.Type: GrantFiled: October 2, 2014Date of Patent: May 26, 2015Inventor: Darin Slack

Publication number: 20150141862Abstract: An electrocardiograph device and methods of navigating displays of such a device are disclosed. In one example, an electrocardiograph device includes a display, a plurality of electrocardiograph signal leads, and a programmable circuit. The programmable circuit is configured to receive electrical signals via the electrocardiograph signal leads representative of a heartbeat of a patient. The programmable circuit is configured to generate a user interface to be presented on the display, the user interface comprising a lead display including a screen layout including a plurality of waveform regions. The waveform regions display a waveform corresponding to an electrical signal from one of the leads over a time interval including at least one heartbeat period. Selection of a region causes display of an extended waveform region displaying a waveform over a second time interval that is longer than the first time interval, and which includes a plurality of heartbeat periods.Type: ApplicationFiled: November 21, 2013Publication date: May 21, 2015Applicant: Welch Allyn, Inc.Inventors: Elaine Carole Montambeau, Kathryn Coles
