The description focuses on signal acquisition, transmission, basic processing (heart rate calculation), and display. There is no mention of AI/ML algorithms for analysis, interpretation, or prediction.
No
The device is described as being for "spot check and short-term monitoring of ECG & heart rate," and its primary functions involve acquiring, transmitting, processing, and displaying physiological signals for monitoring purposes, along with alarms for out-of-range heart rates. It does not perform any direct therapeutic action or deliver therapy.
Yes
The device is intended for "spot check and short-term monitoring of ECG & heart rate of patients," "acquires two channels of electrocardiograph (ECG-A and ECG-B) signals" and "displays heart rate, ECG (ECG-A and ECG-B) waveforms on its LCD display for monitoring purposes." These functions directly involve collecting and analyzing physiological data to assess a patient's health status, which is a characteristic of a diagnostic device, even though it's specified for "monitoring purposes."
No
The device description clearly outlines hardware components: the LifeSignals WiPatch (a wireless ECG patch with electrodes, batteries, and a switch) and the Access Point (a commercially available wireless router). While the system includes software (LifeSignals WiApp Software App), it is part of a larger system that includes dedicated hardware.
Based on the provided information, the LifeSignals WiPatch & WiApp system is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body, such as blood, urine, or tissue, to provide information about a person's health. These tests are performed outside of the body (in vitro).
- Device Function: The LifeSignals WiPatch & WiApp system directly monitors physiological signals (ECG and heart rate) from the patient's body in vivo (within the body). It does not analyze samples taken from the body.
- Intended Use: The intended use is for "spot check and short-term monitoring of ECG & heart rate of patients." This is a monitoring function, not a diagnostic test performed on a sample.
Therefore, the LifeSignals WiPatch & WiApp system falls under the category of a physiological monitoring device, not an In Vitro Diagnostic device.
N/A
Intended Use / Indications for Use
The LifeSignals WiPatch & WiApp system is intended for spot check and short-term monitoring of ECG & heart rate of patients at rest or patients who can be transported within the range of the antenna network. The WiPatch & WiApp system has visual and audio alarms to alert clinical personnel when heart rate falls outside the set limits. The device is intended for use on general care patients of 18 years or older. The device is not intended for use on critical care patients.
The LifeSignals WiPatch & WiApp System is contraindicated for use on patients with active implantable medical devices such as pacemakers, implanted cardioverter defibrillators (ICD) and left ventricular assist devices (LVAD); for use in a magnetic resonance (MR) environment; for use during surgical procedures when electro-surgical equipment is operational.

The LifeSignals WiPatch:
- . is a wireless ECG patch that--when attached to the upper left chest of a patient -continuously acquires physiological signals and transmits these signals wirelessly to any compatible receiver.
- is disposable and integrated with four adhesive electrodes for body interface.
- acquires two channels of electrocardiograph (ECG-A and ECG-B) signals
- transmits acquired signals after initial pre-processing to a compatible receiver wirelessly using the 802.11b communication protocol (2.4 GHz).
- is powered by two-coin cell batteries (zinc air) with an operating life up to 72 hours.
- . has an integrated switch to power it on, and has bi-color LED indicators to indicate the communication status with the receiver.
The LifeSignals WiApp System:
- . consists of a LifeSignals WiApp Software App (WiApp SW), and a compatible commercial iOS device (iPad, iPad 2, iPad Air or iPad Air 2)
- . software, when installed on a compatible hardware, establishes a connection to any one of the LifeSignals WiPatches connected to the same wireless network/Access Point through a pairing process.
- receives the transmitted signals from the paired WiPatch wirelessly, processes the signals and displays heart rate, ECG (ECG-A and ECG-B) waveforms on its LCD display for monitoring purposes by trained clinical personnel.
- . has audio and visual alarms to alert clinical personnel when heart rate of a patient is outside the set limits, lead off, when the battery is low (either the WiPatch or the WiApp System - iPad), or when there is a loss of communication link between the WiApp System and the WiPatch.
Access Point:
An access point is a commercially available hardware device (a.k.a wireless router) that allows wireless capable devices connect through a wireless standard (e.g. 802.11b). LifeSignals WiPatch and WiApp system communicate through an access point.
