Automatic cleaning method and cleaning bed for patient of gatism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Incontinent patients require frequent manual replacement of urine separation pads, which is inconvenient, especially for critically ill patients, as existing hospital beds do not facilitate automatic replacement, leading to contamination of bed sheets and increased workload for medical staff.
Innovation Solution
An automatic cleaning method and bed system that includes a lifting mechanism, flushing device, drying device, clamping mechanism, and cutting mechanism to automate the replacement of urine separation pads, ensuring quick and convenient replacement without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual replacement of urine separation pad is used, then the structure is simple, but the ease of operation deteriorates and productivity decreases
Solution Approach 1:
The automatic replacement system is divided into multiple independent functional modules: a lifting mechanism with first and second lifting mechanisms, a flushing device, a drying device, a clamping mechanism, and a cutting mechanism. Each module performs a specific function in the replacement process, allowing the complex task of pad replacement to be segmented into manageable automated steps that improve ease of operation without requiring the entire system to be redesigned as one complex unit.
Solution Approach 2:
The bed body is designed as a multi-functional platform that integrates not only patient support functions but also automatic pad replacement functions. The bed body incorporates the lifting mechanisms, flushing device, drying device, clamping mechanism, and cutting mechanism, allowing it to serve both as a patient bed and an automatic replacement system. This multi-functionality improves ease of operation by consolidating multiple functions into a single universal device.
2Productivity
If manual replacement of urine separation pad is used, then the device complexity is low, but the productivity deteriorates
Solution Approach 1:
The system prepares the replacement pad in advance by storing it on a material roller ready for deployment. The first lifting mechanism positions the new pad beforehand, and the clamping mechanism is pre-positioned to grab the pad material. This preliminary preparation of replacement materials and mechanisms significantly speeds up the replacement process, improving productivity by eliminating the need for manual search and preparation during the actual replacement moment.
Solution Approach 2:
The system performs the replacement process autonomously through automated mechanisms. The lifting mechanisms automatically position pads, the flushing device automatically cleans the patient area, the drying device automatically dries, the clamping mechanism automatically grabs and moves the new pad, and the cutting mechanism automatically cuts the pad to size. This self-service capability eliminates the need for manual intervention, dramatically improving productivity while the modular design keeps individual components relatively simple.
3Object-affected harmful factors
If urine separation pad is not replaced frequently, then the workload is low, but the bed cleanliness deteriorates
Solution Approach 1:
The system enables continuous monitoring and replacement of the urine separation pad through automated mechanisms. The lifting mechanisms can be activated on demand to check and replace pads, ensuring continuous bed cleanliness without requiring constant manual attention. The automated nature allows the system to maintain cleanliness standards continuously while reducing overall workload, as the system can perform replacements quickly and efficiently whenever needed rather than requiring frequent manual checks.
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
The system reduces the frequency of bed sheet changes and decreases the workload for medical staff by automating the urine separation pad replacement process, maintaining bed cleanliness and tidiness.
Implementation Method 1
starting a lifting mechanism to drive a first belt pulley to rotate so that a flat belt rotates to drive a connecting plate and a soft cushion platform to move downward
Implementation Method 2
ejecting, by a flushing device under a moving plate, clean water to wash an excreting part of the patient
Implementation Method 3
starting a drying device to dry the excreting part washed after the washing is finished
Implementation Method 4
starting a double-shaft cylinder to drive a clamping mechanism to move toward a side of the urine specification pad material
Implementation Method 5
extending a lifting cylinder to reach a second predetermined position
Implementation Method 6
a clamping motor is started to drive a rotary rod to rotate, so as to move a matching block to a side away from the material roller, which in turn drives clamping claws to move toward each other to clamp and move the urine separation pad material
Implementation Method 7
starting a cutting motor of a cutting mechanism to rotate a screw, so as to move a reciprocating block along a path of a spiral groove of the screw
