Medical Alarm Clock Synchronization for Distinguishable Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medical devices, such as infusion pumps, often produce audible and visual alarms that are difficult to distinguish due to interference and constant noise, leading to increased stress for patients and clinicians, and require synchronization to enhance the hospital environment.
Innovation Solution
A system for synchronizing alarms across multiple medical devices using a server with a master clock, enabling synchronized or out-of-sync alarms based on alarm type and location, utilizing Network Time Protocol (NTP) for clock synchronization, and adjusting alarm frequencies to minimize interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple medical devices provide audible and visual alerts simultaneously, then alarm coverage is improved, but alarm distinguishability deteriorates due to interference and constant noise
Solution Approach 1:
The patent segments alarm signals into different synchronization groups based on device location and alarm type. Devices are divided into first and second groups that synchronize independently, allowing alarms to be distinguished by their temporal patterns. This segmentation enables selective synchronization to maintain coverage while improving distinguishability.
Solution Approach 2:
The system dynamically adjusts alarm synchronization based on real-time conditions, including device location, alarm type, and environmental factors. The synchronization state can change from synchronized to out-of-sync based on detected conditions, allowing the system to adapt and optimize both coverage and distinguishability dynamically.
2Reliability
If alarms from multiple devices sound continuously, then monitoring coverage is improved, but patient and visitor stress increases due to constant noise
Solution Approach 1:
The patent implements periodic alarm synchronization where devices switch between synchronized and out-of-sync states in a controlled manner. This periodic action maintains monitoring coverage through regular updates while reducing continuous noise by creating predictable patterns that allow quiet periods between alarm cycles.
Solution Approach 2:
The system uses feedback mechanisms to detect alarm conditions and environmental factors, then adjusts synchronization behavior accordingly. When alarms are detected, the system coordinates device responses to maintain coverage while minimizing overall noise levels through coordinated timing and pattern recognition.
3Reliability
If alarm frequencies are increased to ensure detectability, then alarm reliability is improved, but interference between different alarms increases
Solution Approach 1:
The patent applies different synchronization characteristics to different alarm types and device locations. Critical alarms in specific locations may synchronize differently than non-critical alarms, allowing each alarm to maintain optimal detectability while reducing interference from other alarm types through localized synchronization strategies.

AI summary
A system includes a server including a clock and a plurality of medical devices in network communication with the server. Each medical device includes at least one alarm mechanism and an internal clock. A first medical device of the plurality of medical devices is configured to receive a clock synchronization data from the server, update the internal clock of the first medical device based on the clock synchronization data, provide an alarm signal of a first type at a first time, and provide a subsequent alarm signal of the first type at a second time. The second time occurs at a predetermined interval from the first time. Additionally, the second time is the same time the alarm signal of the first type is provided by a second medical device of the plurality of medical device.
