Medical Device Heater With Top-Loading Receptacle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The insertion and removal of liquid-carrying components, such as heating bags, in medical devices like dialysis machines are complex due to the need for compression and subsequent filling, making the process laborious and time-consuming, especially during dismantling when the bags are filled.
Innovation Solution
A heater design with a receptacle that has an opening on a side other than the front, allowing for easy insertion and removal of liquid-carrying components without prior compression, featuring a slot-shaped opening on the front side surface to guide hose sections without kinks, and a temperature control system with sensors for regulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the heating element is inserted through a slot on the front of the heater, then the heating element can be inserted into the heater, but the insertion process requires compression and subsequent filling which makes it cumbersome and time-consuming
Solution Approach 1:
The patent inverts the conventional front-opening design by providing the opening at the top of the heater housing. This allows the heating element to be inserted from the top in a natural downward motion without requiring compression through a front slot, thereby simplifying the insertion process and reducing the time required.
2Ease of operation
If the heating element is inserted through a slot on the front of the heater, then the heating element can be inserted into the heater, but the removal process requires displacing liquid and is time-consuming
Solution Approach 1:
The patent inverts the conventional front-opening design by providing the opening at the top of the heater housing. This allows the heating element to be removed from the top in a natural upward motion without requiring liquid displacement, thereby simplifying the removal process and reducing the time required.
3Adaptability or versatility
If the opening is located on the front of the heater, then the heating element can be inserted, but the heating element cannot be removed while filled
Solution Approach 1:
The patent inverts the conventional front-opening design by providing the opening at the top of the heater housing. This allows the heating element to be removed from the top even when filled with liquid, providing operational flexibility and adaptability that was not possible with front-opening designs.
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
Simplifies the insertion and removal of liquid-carrying components, reducing operational time and effort, while ensuring easy dismantling without emptying the heating bags, and enabling efficient temperature control and monitoring.
Implementation Method 1
insert components or disposable components of a fluid-carrying system into a heater in order to heat up or warm the fluid in the fluid system
