Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hospital beds struggle to communicate effectively with nurse call systems and room devices due to differences in communication protocols and outlet configurations across various healthcare facilities, requiring individual configuration of each bed.
Innovation Solution
A portable configuration tool that uses a combination of infrared and RF transceivers to communicate with headwall units, allowing technicians to configure these units to match specific nurse call systems and room devices, thereby enabling uniform communication across different healthcare facilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If patient support apparatuses are individually configured to match different nurse call systems and room devices, then communication compatibility is achieved, but configuration time and complexity increase significantly
Solution Approach 1:
The patent introduces a headwall unit as an intermediary device between the patient support apparatus and the nurse call system/room devices. The headwall unit is configured once to match the facility's communication infrastructure, and then multiple patient support apparatuses can uniformly communicate through it without individual configuration. This mediator absorbs the adaptation complexity, allowing standardized patient support apparatuses to work across different facilities.
Solution Approach 2:
The configuration is performed in advance on the headwall unit during facility setup rather than on each patient support apparatus when deployed. The headwall unit stores pre-configured communication parameters and protocols specific to the facility's nurse call system and room devices, enabling patient support apparatuses to begin operation immediately with default settings.
2Reliability
If each patient support apparatus is configured individually to match specific communication outlets, then communication accuracy is ensured, but device complexity and configuration difficulty increase
Solution Approach 1:
The headwall unit serves as a centralized configuration point that interfaces with the facility's specific communication outlets and systems. It translates and adapts communication signals between the standardized patient support apparatuses and the facility-specific infrastructure, ensuring reliable communication without requiring complex individual configuration of each bed.
Solution Approach 2:
The headwall unit is designed to handle multiple communication functions and protocols simultaneously, serving as a universal interface for different nurse call systems and room devices. This multi-functional approach allows a single configuration system to support various communication standards without requiring specialized configuration for each patient support apparatus.
3Ease of manufacture
If patient support apparatuses are manufactured with uniform communication capabilities, then manufacturing efficiency improves, but adaptability to different healthcare facility infrastructures decreases
Solution Approach 1:
The headwall unit acts as an adaptive intermediary that bridges the gap between uniformly manufactured patient support apparatuses and diverse facility infrastructures. The headwall can be configured to speak different communication protocols and interfaces, allowing standardized patient support apparatuses to work seamlessly across different healthcare facilities without requiring customization during manufacturing.
Solution Approach 2:
The system separates static patient support apparatuses with fixed communication capabilities from the dynamic headwall unit that can be adapted and reconfigured for different facilities. This dynamic element at the headwall level provides the necessary versatility while keeping the patient support apparatus manufacturing simple and uniform.

AI summary
A portable configuration tool for configuring a headwall unit that is adapted to be electrically coupled to an outlet on a headwall communicates with a room device positioned within a common room with the headwall unit. The tool includes a housing, a transceiver for communicating with a portable computer, IR and RF transceivers for communicating with the headwall unit, and a controller adapted to receive a command from the portable computer that instructs the controller to transmit an initial message to the headwall unit using the infrared transceiver, receive an identifier from the headwall unit via the infrared transceiver that uniquely identifies the headwall unit, establish a communication link between the RF transceiver and the headwall unit, receive a configuration setting from the portable computer via the transceiver, and transmit the configuration setting to the headwall unit via at least one of the infrared or RF transceivers.
