Modular Patient Transfer System for Single-Caregiver Multi-Service
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for safe patient handling are inadequate for providing multiple services to bedridden patients without patient cooperation, as they are complex, expensive, and difficult to use, and lack practical solutions for complex multi-service and mobility by a single caregiver.
Innovation Solution
A mechanized patient transfer-treatment center (PTTC) system that enables multi-service and mobility for bedridden patients by a single caregiver, featuring a mechanized system of vertical movements and engagement seats, allowing for transfer and service without repositioning the patient, using a line of customized assemblies that support patients in a suspended position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing SPH devices are used, then patient handling is supported, but the devices are complex, expensive, and hard to use for multi-service by a single caregiver
Solution Approach 1:
The system is divided into separate functional modules: a mobile base unit with wheels for mobility, a vertical support structure with motorized lifting mechanism, and a service platform with replaceable seats. This segmentation allows each component to perform its specific function independently, reducing overall system complexity while maintaining ease of operation for single caregiver use.
Solution Approach 2:
The service platform is designed with replaceable seats that can be configured for multiple services (e.g., hygiene services, treatment services, transfer services). This multi-functionality allows a single device to perform various patient handling tasks without requiring multiple separate devices, thereby reducing complexity and cost while improving ease of operation.
2Reliability
If existing SPH devices are used, then patient handling is supported, but the devices are expensive
Solution Approach 1:
By dividing the system into modular components (mobile base, vertical support, service platform), the patent reduces manufacturing costs and material requirements while maintaining reliable patient handling capabilities. Each module can be independently manufactured and assembled, reducing overall system cost without compromising reliability.
Solution Approach 2:
The system incorporates motorized lifting mechanisms and automated seat replacement capabilities that reduce the need for complex manual operation systems. This self-service approach lowers the complexity of control systems while maintaining reliable patient handling, and reduces operational costs for caregivers.
3Adaptability or versatility
If bedridden patients are served without patient cooperation, then multi-service is enabled, but the devices lack practical solutions for complex transfers and mobility
Solution Approach 1:
The system features a mobile base with wheels that can be dynamically positioned and moved to different locations. The vertical support structure can dynamically adjust heights and angles to accommodate various transfer scenarios. This dynamic adaptability enables the system to handle complex transfers and mobility requirements while maintaining ease of operation through automated adjustments.
Solution Approach 2:
The service platform acts as an intermediary between the bed and various service locations. It provides a controlled environment where patients can be transferred and services can be performed without requiring direct manual handling or repositioning of the patient. This intermediary mechanism enables multi-service capability while maintaining ease of operation through automated patient support.

AI summary
Two-seat mechanized patient transfer-treatment system that enables a single caregiver to move and deliver multi-services directly to bedridden and low-mobility patients at any time and distance from the support surface without removing the patient from the support seat. The system provides a chain of temporarily built service assemblies, of a top unit to which two seats can be removably connected and one of a quantity of different mobile or stationary bases, adapted for modification to serve a sequence of multifunctional indoor-outdoor operations, and wherein a single caregiver can make changes at any time during the service.
