Infusion Guiding Robot With Autonomous Navigation for Patient Mobility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transfused patients face difficulties in moving due to the connection with infusion containers and navigating unfamiliar hospital environments, leading to inconvenience for both patients and caregivers, especially when accessing facilities like bathrooms or requesting nurse assistance.
Innovation Solution
A transfusion guiding robot equipped with a controller, moving portion, and adjustable fixing portion, featuring omni-directional wheels, obstacle avoidance sensors, navigation devices, and a safety cord, allowing patients to independently move to desired locations and communicate with nurses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a transfused patient is connected to an infusion container, then the patient can receive necessary medical treatment, but the patient loses mobility and independence in moving around the hospital environment
Solution Approach 1:
The robot acts as an intermediary carrier between the patient and the infusion container. It equips itself with the infusion container and connects to the patient via a safety cord, serving as a mobile intermediary that provides both treatment delivery and mobility assistance. This resolves the contradiction by separating the treatment function (maintained through the robot-container-patient connection) from the mobility function (provided by the robot's autonomous movement capabilities).
Solution Approach 2:
The robot enables the patient to move independently without requiring nurse assistance. By autonomously navigating to destinations, avoiding obstacles, and maintaining the infusion connection, the robot allows the patient to self-service their mobility needs while continuing to receive medical treatment. This transforms a previously nurse-dependent task into a patient-autonomous activity.
2Ease of operation
If a patient moves independently in an unfamiliar hospital environment, then patient independence is enhanced, but navigation safety and obstacle avoidance become critical challenges
Solution Approach 1:
The robot performs preliminary actions by pre-planning navigation routes, pre-detecting obstacles in the environment, and pre-positioning itself before the patient needs to move. The system constructs environment maps and establishes movement routes in advance, ensuring safe navigation is prepared before actual patient movement occurs. This proactive approach enhances both independence and safety.
Solution Approach 2:
The robot employs continuous feedback mechanisms through obstacle avoidance sensors that detect the environment in real-time and provide feedback to the navigation system. This feedback loop allows the robot to dynamically adjust its path, avoid unexpected obstacles, and maintain safe operation throughout the patient's journey. The laser radar and sensors continuously monitor surroundings and feed this information back to update navigation decisions.
3Adaptability or versatility
If the fixing portion height is made adjustable, then adaptability to different patients is improved, but device complexity increases
Solution Approach 1:
The fixing portion is designed with dynamic height adjustment capability, allowing it to adapt to different patient heights and requirements. The support post and bracket assembly can be raised or lowered to accommodate various patients, transforming a static structure into a dynamic, adaptable one. This dynamic feature enhances patient adaptability while maintaining relatively simple mechanical adjustment mechanisms.
