Mobile negative pressure chamber
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The rapid spread of infectious diseases, such as COVID-19, has led to challenges in isolating patients and providing timely medical treatment, especially in emergency situations where negative pressure wards are not readily available.
Innovation Solution
A mobile negative pressure chamber is designed to allow for the isolation and treatment of patients with respiratory infectious diseases during transport. The chamber includes a bed, separable main and auxiliary covers with negative pressure cavities, and treatment parts with glove and insertion/extraction ports to enable medical procedures while maintaining isolation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a conventional negative pressure device for transport is used, then patient isolation is achieved, but medical treatment and diagnosis cannot be performed during transport
Solution Approach 1:
The chamber is divided into multiple separable covers (first cover, second cover, third cover) that can be independently removed and reattached. This segmentation allows the chamber to transition between sealed isolation mode and open treatment mode, enabling both isolation and medical procedures without compromising either function.
Solution Approach 2:
The chamber design incorporates dynamic configurability where covers can be selectively opened or closed based on operational needs. The separable cover structure allows the system to adapt between maintaining negative pressure isolation and allowing medical staff access for treatment, resolving the contradiction between isolation effectiveness and medical procedure capability.
2Quantity of substance
If an entire negative pressure ward is temporarily constructed outdoors, then isolation capacity is increased, but medical staff are still exposed to infectious agents and treatment capabilities are limited
Solution Approach 1:
The chamber utilizes a flexible, sealed structure with separable covers that can be quickly assembled and disassembled. This flexible shell design creates an effective isolation barrier that protects medical staff while allowing controlled access for medical procedures, eliminating the need for staff to wear extensive protective gear and enabling treatment within the isolation environment.
3Object-affected harmful factors
If a sealed negative pressure device is used for transport, then patient isolation is maintained, but the device complexity increases
Solution Approach 1:
The chamber is divided into multiple separable covers that can be independently handled and reattached. This segmentation simplifies the overall structure compared to a fully sealed monolithic design, while still maintaining effective isolation when assembled. The modular nature reduces complexity by allowing simple connection interfaces between components.
