Hospital Bed Drainage Bag Sensing for Integrated Patient Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current patient bed systems lack integrated solutions for enhanced patient and caregiver interaction, efficient bed functionality control, and seamless integration of therapeutic features, leading to limitations in patient mobility and therapy delivery.
Innovation Solution
A bed control cart with a wheeled base, GUI, and circuitry that sends wireless signals to control bed features, including foot and hand inputs for adjusting the bed's position, mattress therapy functions, and communication with other healthcare equipment, along with integrated sensors and display systems for patient monitoring and alarm management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a bed control cart with wireless signals is used to control bed features, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent replaces traditional mechanical control systems with wireless communication technology. The bed control cart uses wireless transmitters and receivers to send control signals to the patient bed, eliminating the need for physical connections and mechanical control interfaces. This substitution improves ease of operation while managing device complexity through software-based solutions.
2Measurement precision
If integrated sensors and display systems are added for patient monitoring, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple monitoring functions including drainage bag sensors, patient position detection, and alarm systems into an integrated monitoring platform. The control cart consolidates these various sensing and display functions into a single unified system, improving measurement precision while managing complexity through integration rather than separate systems.
Solution Approach 2:
The bed control cart is designed as a universal platform that can perform multiple functions: controlling bed position, monitoring patient status through integrated sensors, displaying information, and communicating with other healthcare equipment. This multi-functionality approach improves measurement capabilities while avoiding the complexity of multiple separate devices.
3Ease of operation
If wireless communication is used to control bed features and communicate with healthcare equipment, then ease of operation is improved, but reliability may worsen
Solution Approach 1:
The patent implements feedback mechanisms in the wireless communication system. The bed control cart receives confirmation signals from the patient bed to verify that control commands were successfully transmitted and executed. This feedback loop ensures reliable operation by allowing the system to detect and potentially retransmit failed commands, maintaining reliability while preserving ease of operation.

AI summary
A patient bed includes a drainage bag sensor. The patient bed includes, for example, a frame configured to support a patient, a drainage bag holder coupled to the frame and configured to support a drainage bag, and a sensor to detect a presence of the drainage bag being supported by the drainage bag holder.
