The LifeBed Patient Vigilance System is intended to measure heart rate and respiratory rate in adult patients, in bed, in a general care hospital environment. The system will also monitor bed exit.

Device Description

The LifeBed Patient Vigilance System consists of two (2) main components: the bedside unit and the Passive Sensor Array™ (PSA™). The bedside unit houses the digital signal processing algorithms that calculate heart and respiratory rates and bed exit status (in-bed sensor) in real time and displays the data as part of the integrated graphical user interface. The bedside unit houses the alarm logic and interfaces to the existing nurse call system found in the hospital. The PSA is comprised of a mattress ticking ("coverlet" that slips over the entire mattress) that houses an array of sensors, which connect to the bedside unit via a cable with an integrated "quick disconnect" safety feature.

The LifeBed Patient Vigilance System's Passive Sensor Array (PSA) technology analyzes basic heart and respiratory physiology without direct patient contact, eliminating the use of electrodes, wires and leads. Hoana's PSA technology integrates proprietary signal processing algorithms with patented data collection devices that produce an electrical signal in response to physiological stimuli. The LifeBed Patient Vigilance System passively extracts patient measurements even through clothing, gowns or sheets.

AI/ML Overview

This 510(k) submission, K082366, is a Special 510(k) for a change to the Graphical User Interface (GUI) of the LifeBed Patient Vigilance System. As such, the submission explicitly states there are "no changes to the original submission" and "no change in the fundamental scientific technology of the device" or "indications for use." Therefore, detailed device performance studies or acceptance criteria comparisons are not included, as the modification is ergonomic, not related to the underlying physiological measurement accuracy.

However, based on the information provided, we can infer some details and state where specific information is not present:

1. Table of Acceptance Criteria and Reported Device Performance

As this is a Special 510(k) for a GUI change, detailed performance criteria (e.g., accuracy for heart rate or respiratory rate) and associated reported device performance are not provided in this document. The focus is on the human-computer interaction, not the physiological measurement accuracy.

2. Sample Size Used for the Test Set and Data Provenance

This information is not provided as the submission pertains to a GUI change, not a new performance study.

3. Number of Experts Used to Establish Ground Truth and Their Qualifications

This information is not provided as the submission pertains to a GUI change, not a new performance study requiring expert ground truth for physiological measurements.

4. Adjudication Method

This information is not provided as the submission pertains to a GUI change, not a new performance study.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

A MRMC comparative effectiveness study was not conducted or reported in this submission. This type of study would be relevant for evaluating human interpretation of medical images or diagnostic tests, which is not the primary function of a GUI change in a patient vigilance system.

6. Standalone Performance (Algorithm Only)

A standalone performance study was not detailed in this submission. For a GUI change, the accuracy of the underlying algorithms (heart rate, respiratory rate, bed exit) is assumed to have been established in the original 510(k) for the LifeBed system.

7. Type of Ground Truth Used

The document does not specify the type of ground truth used, as it focuses on software ergonomics rather than clinical efficacy.

8. Sample Size for the Training Set

This information is not provided as the submission pertains to a GUI change, not a new algorithm development requiring a training set.

9. How the Ground Truth for the Training Set Was Established

This information is not provided as the submission pertains to a GUI change, not a new algorithm development requiring a training set.

Summary of the Study that Proves the Device Meets Acceptance Criteria (as per this Special 510(k)):

The "study" that proves the device meets the acceptance criteria in this specific Special 510(k) is the design control process itself, as stated in the Conclusion section: "summary information that results from the design control process can serve as the basis for clearing the application."

The acceptance criteria for this Special 510(k) are implicitly:

The GUI change does not affect the intended use of the device.
The GUI change does not alter the fundamental scientific technology of the device.
There are no changes in the indications for use.
There are no changes to labeling that affects the intended use.
There are no changes in materials.
The ergonomics of the patient-user interface (the GUI change) is appropriate.

The basis for meeting these criteria is the absence of changes to the core functionalities, indications, and technology of the device, as asserted by the manufacturer and accepted by the FDA for a Special 510(k) pathway. The "study" per se is the internal design and verification documentation demonstrating that the GUI modification is limited in scope and does not impact safety or efficacy beyond the change in user interface presentation. Electrical, Mechanical, EMC, and Biocompatibility testing (per IEC 60601-1-2 and ISO 10993) were performed on the LifeBed system generally, and likely confirmed no adverse impacts from the GUI integration, but these tests are not specific to the GUI performance itself.

Description of the LifeBed Patient Vigilance System:

{1}------------------------------------------------

Intended Use

The LifeBed Patient Vigilance System is intended to measure heart rate and respiratory rate in adult patients, in bed, in a general care hospital environment. The system will also monitor bed exit,

Principles of Operation

The LifeBed Patient Vigilance System operates in the following manner. The bed on a general care floor is fitted with the sensing array built into a sleep surface coverlet. Each bed is then fitted with a normal sheet and bedding above the coverlet.

The device measures heart rate and respiration and monitors those against a preset limit. If the bedside unit senses the heart rate or respiration rate is outside the desired limits for a period of time, it will signal the nurse with an alarm indicator using the standard nurse call system and the clinician will respond. If the patient has been evaluated as a risk to fall, the bed exit alarm can also be enabled. When the unit senses the patient is attempting to get out of bed, it will use the nurse call system to signal the nurse.

The system will trend and display graphics of heart rate and respiration rate and wave form graphic for respiration in 10 minute, 2, 4, 8, and 12 hour views of the data.

Electrical, Mechanical and EMC Testing

Electrical, Mechanical and EMC Testing per IEC 60601-1-2 was performed and the LifeBed Patient Vigilance System passed all tests.

Biocompatibility Testing

Biocompatibility was conducted according to the requirements of ISO 10993. Biological Evaluation of Medical Devices, Table 1 - Initial Evaluation Tests for Consideration for a surface device in contact with skin for less than 24 hrs. All test article materials passed.

Conclusion

This Special 510(k) submission covers only the change in the Graphical User Interface (GUI). This change meets the criteria for Special 510(k) under the New 510(k) Paradigm, which states that if the modification does not affect the intended use of the device or alter the fundamental scientific technology of the device, then summary information that results from the design control process can serve as the basis for clearing the application.

There is no change in the indications for use.

There are no changes to labeling that affects the intended use.

There is no change in the fundamental scientific technology of the device.

There are no changes in materials.

Device modifications that should be appropriate for review as a Special 510(k) include "ergonomics of the patient-user interface." This change in GUI is the only change to the original submission covered by this Special 510(k).
