Solution Overview

Problem

Existing patient monitoring systems face challenges with cable management and patient discomfort due to the extensive use of cables connecting various sensors and monitors, leading to interference with patient movement and caregiver interaction.

Innovation Solution

A patient monitoring system design that minimizes cable length by allowing indirect connections between sensors, such as the ECG device connecting directly to the blood pressure monitor, which then connects to the patient monitor, and incorporates cable management prongs to secure cables in place, reducing the overall cable length and improving patient comfort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If cables are used to connect sensors and monitors directly, then data transmission reliability is improved, but patient comfort deteriorates and patient movement is interfered with

Engineering Contradiction:

Improvedata transmission reliabilityVSAvoidpatient discomfort

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces wireless communication modules as intermediaries between sensors and monitors, replacing direct cable connections. The sensors transmit physiological data wirelessly to the monitor through radio frequency communication, eliminating the need for physical cables that cause patient discomfort while maintaining data transmission reliability.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent extracts and removes the cables from the patient monitoring system. By implementing wireless communication capabilities directly in the sensors and monitors, the system eliminates the harmful cable connections while preserving the essential data transmission function.

Inventive Principle:

Principle #2Taking out (Extraction)

2Reliability

If cables are used to connect various sensors and monitors, then data transmission is maintained, but device complexity increases due to cable management requirements

Engineering Contradiction:

Improvedata transmissionVSAvoidcable management

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical cable connection system with an electromagnetic wireless communication system. Sensors and monitors are equipped with wireless transceivers that communicate physiological data through radio waves, eliminating the mechanical cable infrastructure and its associated management complexity.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent implements multi-functional integrated units that combine sensing, processing, and wireless communication capabilities. This consolidation reduces the number of separate components and connections needed, simplifying the overall system architecture while maintaining reliable data transmission.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Stability of the object's composition

If cable management prongs are used to secure cables, then cable stability is improved, but patient movement is still restricted

Engineering Contradiction:

Improvecable stabilityVSAvoidpatient movement

Core Design Contradiction:

Stability of the object's compositionVSEase of operation

Solution Approach 1:

The patent introduces wireless communication as an intermediary that eliminates the need for physical cable stabilization mechanisms. By transmitting data through electromagnetic waves rather than physical cables, the system achieves stable data transmission without restricting patient movement with cable management prongs or other mechanical constraints.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A noninvasive blood pressure monitor. The noninvasive blood pressure monitor may include an inflatable cuff, a pressure transducer, one or more air pumps, and a processor. The processor may control the air pump(s) so as to initiate inflation of the cuff. The processor may also identify an oscillometric signal in an output of the pressure transducer, and may determine an envelope of the oscillometric signal. The processor may also determine one or more characteristics of the envelope of the oscillometric signal, and may control the air pump(s) so as to stop inflation of the cuff based on the one or more characteristics of the envelope of the oscillometric signal.
