Bedpan Cleaner with Integrated Hand Disinfection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Nursing staff often fail to regularly disinfect their hands when handling used bedpans and urine bottles, leading to potential germ spread and infection risks due to time pressure and forgetfulness during daily work.
Innovation Solution
Incorporating a disinfection unit connected to the control unit within a bedpan and urine bottle cleaning device, which ensures users disinfect their hands before and after the cleaning process by transmitting release signals to control the sequence of operations, including reminders and automatic program initiation or completion based on disinfection unit usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hand disinfection is made mandatory through control unit integration, then germ spread prevention is improved, but device complexity increases
Solution Approach 1:
The patent combines the hand disinfection function with the bedpan cleaning device by integrating a disinfection unit (spray chamber or dispenser) into the device housing. The control unit monitors disinfection unit usage and controls the cleaning program execution, merging two separate functions (hand disinfection and bedpan cleaning) into a single integrated system. This resolves the contradiction by making germ spread prevention reliable through integration while managing complexity through functional consolidation.
Solution Approach 2:
The control unit receives feedback signals from the disinfection unit indicating whether it has been used. Based on this feedback, the control unit determines whether to execute the cleaning program or display reminder signals. This feedback mechanism ensures reliable germ spread prevention by verifying disinfection occurs, while managing complexity through automated monitoring rather than manual tracking.
2Reliability
If disinfection unit usage is monitored and control program execution is linked to it, then hygiene protocol compliance is improved, but ease of operation deteriorates
Solution Approach 1:
The system automatically monitors whether the disinfection unit has been used and automatically controls the execution of the cleaning program based on this information. The control unit displays reminder signals and can prevent program execution until disinfection is confirmed. This self-service approach improves hygiene protocol compliance through automated enforcement while maintaining ease of operation by reducing the cognitive burden on users to manually track disinfection status.
3Productivity
If automated reminders and control linkage are implemented, then regular disinfection frequency is improved, but device complexity increases
Solution Approach 1:
The control unit serves multiple functions: it controls the cleaning program execution, monitors disinfection unit usage, displays reminder signals, and manages the overall operation sequence. By making the control unit multi-functional, the patent improves regular disinfection frequency through automated reminders and control linkage while minimizing the increase in device complexity by utilizing existing control infrastructure for multiple purposes.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively minimizes germ spread by ensuring regular hand disinfection of nursing staff, preventing contamination and ensuring proper hygiene protocols are followed, even under time constraints.
Implementation Method 1
A novel system for disinfecting parts of a user's skin is what is known as cold plasma disinfection. Disinfection is carried out by applying plasma to the skin areas to be disinfected, here in particular to the hands to be disinfected.
Implementation Method 2
the disinfection unit comprises at least one sensor and that the presence of at least one hand of a user can be detected with the sensor
