Record sleep at home! The Zmachine Insight+ provides accurate EEG-based sleep staging information in a system that is easy-to-operate, unobtrusive and patient-friendly.
General Sleep offers Zmachine Comfort 40 sensors by the case. Each case contains 40 packages of sensors (enough for 40 nights of use), and can be obtained directly from General Sleep.
The Zmachine Data Viewer software, which is available as a free download on our website, will run on any computer running the Windows 7 or later operating system, and Apple computers running Windows emulators. This software is powerful, easy-to-use, and runs locally on your PC to display, graph, analyze, and organize your Zmachine data. If you wish to read the files directly (i.e. without the data viewer), all sleep scoring reports and sleep statistic summaries are stored as ASCII .csv (comma separated variable) files. They can be opened directly using Excel, Matlab, text editors and statistics programs. The raw EEG data is stored as 2-Byte unsigned integers (little-endian), 16-bit resolution, and sampled at 2500Hz. Sample Matlab code available in the Support section for loading the raw EEG data files.
The very act of sleeping precludes conscious knowledge of time and events, and reliance on subjective self-reports of sleep, without objective data, can lead to an incomplete and potentially misleading picture. With the Zmachine Insight, you can now obtain objective sleep information based on the EEG signal. Automatically scored wake, light sleep, deep sleep and REM is recorded every 30 seconds in the patient’s home where sleep is most natural.
Not really. The Zeo was strictly a consumer product that made no medical or performance claims, whereas the Zmachine is a medical device that is cleared and regulated by the US FDA, and manufactured in FDA registered facilities. The Zmachine is intended for use by medical professionals, academic and industrial researchers.
The Zmachine Insight+ system uses one-time-use, self-stick, disposable EEG sensors. Sensors are located completely outside of the normal hairline (mastoids and neck/shoulder ground), and are easily self-applied by the patient. As opposed to the forehead or other more obtrusive locations, the location of the sensors does not interfere with sleep. The Zmachine Insight+ is small, portable, and battery operated for safe and convenient in-home use.
No. The Zmachine was specifically designed for convenient, in-home use and requires very little technical knowledge to apply. The Zmachine system includes an easy-to-read User Guide, and General Sleep has produced several short videos illustrating various aspects of setting up and using the system.
No. While the data revealed by the Zmachine is highly relevant to sleep specialists and researchers, the intimate knowledge of a patient’s sleep can be highly beneficial to healthcare providers across a wide spectrum of medical specialties. Pain Management, Neurology, Sports Medicine, Geriatrics and many others are all discovering new uses for the valuable information provided by the Zmachine system. Through its unique combination of accuracy and ease-of-use, the Zmachine is making information available to healthcare providers which was previously unavailable.
The Insight+ can display any combination of EEG-derived Total Sleep Time, Sleep Efficiency, Latency to Persistent Sleep, and Wake After Sleep Onset, or none at all, and is displayed each time the user disconnects from the Zmachine. Information is updated in real time and pertains to the current night of sleep. This feature can be especially useful in treating insomnia patients with sleep state misperception.
Yes. Data from the Zmachine microSD card can be transmitted via an e-mail attachment or uploaded directly to your web portal. This information can then be imported directly into the Zmachine data viewer. No user identifiable information is contained in the Zmachine data file. Instructions are included with the Zmachine system. Healthcare providers can use this capability to receive the data files in advance of face-to-face visits to improve work flow and/or reduce the total number of visits needed. Researchers can use this capability to work remotely with test subjects to monitor compliance and/or ongoing results.
Yes, replacement accessories for your Zmachine system can be purchased directly from General Sleep. Please contact us for more details.
Using objective EEG-derived sleep state information, the Insight+ can also be programmed to produce an alert to leave bed when sleep isn’t achieved within a pre-specified period of time. This can be helpful in assisting those patients that spend too much time in bed awake in knowing when they should leave bed and stop trying to fall asleep for a while. The parameters of this alert generation can be enabled/disabled or customized by the clinician.
