Solution Overview
Problem
Existing disinfection methods for ventilation therapy devices leave residues and pose safety hazards, require complex operations, and fail to effectively disinfect the gas channel from the gas inlet to the gas outlet, risking germ contamination and potential disease transmission.
Innovation Solution
A disinfection apparatus comprising a first power unit, heating unit, and gas transfer unit that generates high-temperature disinfecting gas to thoroughly disinfect the gas channel, leaving no residues and ensuring safety with easy operation and low cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing disinfection methods (ethylene oxide, hydrogen peroxide plasma, ultraviolet light, etc.) are used to sterilize the external surfaces and water tank of the ventilation therapy device, then the external components are disinfected, but the gas channel from the gas inlet to the gas outlet cannot be effectively disinfected, leaving a risk of germ contamination
Solution Approach 1:
The patent uses gas flow (pneumatics) to transport the disinfectant through the entire gas channel of the ventilation device. The disinfectant is carried by pressurized gas from the gas inlet through the gas passage to the gas outlet, ensuring complete coverage of the gas channel system which cannot be achieved by surface disinfection methods alone.
Solution Approach 2:
The patent introduces a gas channel as an intermediary medium to deliver the disinfectant throughout the entire gas passage system. This intermediary gas channel allows the disinfectant to reach all internal surfaces of the gas pathway, including areas inaccessible to external disinfection methods.
2Reliability
If existing disinfection methods are used, then disinfection is performed, but residues remain after disinfection requiring professional tests, complicated operations, cumbersome procedures, high costs, and potential safety hazards
Solution Approach 1:
The patent replaces complex mechanical and chemical disinfection systems with a simpler thermal field-based disinfection method. Instead of using chemical disinfectants that require handling, testing, and safety procedures, the system uses heated air flow to achieve disinfection through temperature alone, eliminating residues and simplifying operations.
Solution Approach 2:
The patent changes the parameter of the gas from ambient temperature to high temperature to achieve disinfection. By heating the gas to a sufficient temperature before passing it through the gas channel, the system achieves effective disinfection without chemical residues, eliminating the need for complex testing procedures.
3Reliability
If existing disinfection methods with chemical agents are used, then disinfection is achieved, but residues are left in the device requiring professional tests before reuse
Solution Approach 1:
The patent replaces chemical disinfection mechanisms with a thermal field mechanism. Instead of using chemical agents that leave residues, the system uses heated air to achieve disinfection through thermal effects alone, ensuring no harmful residues remain in the gas channel after the disinfection process.
