Solution Overview

Problem

Current medical device interrogation systems lack remote control over patient-initiated interrogations, leading to potential battery depletion, increased caregiver resources, and liability issues, without controlling the frequency of medical device interactions.

Innovation Solution

A system and method that include a patient management device interfacing with medical devices, allowing caregiver-specified schedules and criteria to control the frequency and permissibility of patient-initiated interrogations, ensuring autonomous and patient-initiated interrogations operate independently with defined limits.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If patient-initiated interrogation is allowed without restrictions, then patient convenience and data availability are improved, but battery life deteriorates and caregiver resource burden increases

Engineering Contradiction:

Improvepatient convenienceVSAvoidbattery life

Core Design Contradiction:

Ease of operationVSDuration of action of moving object

Solution Approach 1:

The system dynamically adjusts the state of the medical device interrogation interface based on received controls. When a disable control is received, the interface is prevented from initiating interrogations; when an enable control is received, the interface is restored. This dynamic state change allows the system to balance patient convenience with battery conservation based on caregiver directives.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system introduces an intermediary control mechanism (enable/disable controls transmitted via communication network) between the patient and the medical device interrogation function. This intermediary allows caregivers to remotely manage interrogation permissions, preventing unrestricted patient-initiated interrogations that would deplete battery while maintaining patient access when authorized.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If patient-initiated interrogation is allowed without restrictions, then data retrieval capability is improved, but caregiver workload and liability exposure increase

Engineering Contradiction:

Improvedata retrieval capabilityVSAvoidcaregiver resource management

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The communication network serves as an intermediary that transmits enable/disable controls from caregivers to the medical device. This intermediary mechanism simplifies caregiver workload by enabling remote management through standardized control signals, while maintaining versatile data retrieval capability when authorization is granted.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system requires preliminary authorization (enable control) before allowing patient-initiated interrogations. This preliminary action prevents unauthorized or excessive interrogations that would increase caregiver workload, while still permitting data retrieval capability when properly authorized in advance.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If unrestricted patient-initiated interrogation is permitted, then patient autonomy is improved, but device battery depletion and premature replacement risk increase

Engineering Contradiction:

Improvepatient autonomyVSAvoidbattery depletion

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The interrogation interface dynamically transitions between enabled and disabled states based on received controls. This dynamic behavior preserves patient autonomy when enabled while preventing battery depletion when disabled, allowing the system to adapt to different operational requirements without compromising either patient autonomy or battery life.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system implements feedback through the transmission of enable/disable controls from caregivers to the medical device. This feedback loop allows real-time adjustment of patient-initiated interrogation permissions, balancing patient autonomy with battery conservation based on clinical needs and device status.

Inventive Principle:

Principle #23Feedback

AI summary

A system and method for managing locally-initiated medical device interrogation is presented. An interface is provided over which to retrieve patient data recorded and transiently staged by a medical device monitoring physiological measures of a patient. The patient data is periodically retrieved by interfacing to and interrogating the medical device per a pre-defined schedule through the interface. Further retrieval of the patient data is permitted independent of the pre-defined schedule. The system stores remotely-specifiable criteria specified by a caregiver and controls patient-initiated patient data retrieval in accordance with the criteria.
