Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ventilator adapters for devices like Respimat pose risks of infection to healthcare workers and patients due to moisture splashing and air leakage during disconnection and reconnection, and they often fail to deliver medication effectively due to leakage and insufficient air pressure, leading to Shear Force Injury and reduced medication absorption.
Innovation Solution
A ventilator adapter with a T-shaped flow guiding adapter and an auxiliary chamber, featuring a guiding valve and chamber partition, which forms an air flow channel to ensure complete medication delivery and maintain airtightness, reducing the risk of infection and improving medication absorption by directing airflow effectively to the patient.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the ventilator circuit is disconnected and reconnected during medication administration, then the spray solution can be administered, but the risk of infection increases due to moisture splashing and air leakage
Solution Approach 1:
A T-shaped adapter is introduced as an intermediary component between the ventilator circuit and the spray solution container. The adapter includes a receiving chamber that receives the spray solution container, with a sealing structure that seals between the container and the adapter. This intermediary device enables medication administration while maintaining circuit integrity and preventing infection risk during the process.
Solution Approach 2:
The system is segmented into distinct functional components: the ventilator circuit, the T-shaped adapter with receiving chamber, and the spray solution container. This segmentation allows the spray solution to be administered through a dedicated receiving chamber that can be sealed independently, preventing moisture splashing and air leakage that would occur with complete circuit disconnection.
2Ease of operation
If the adapter has insufficient length or improper shape, then the spray solution can be connected, but medication leakage occurs
Solution Approach 1:
The adapter incorporates a sealing structure with specific geometric parameters including a sealing surface and sealing chamber designed to match the spray solution container dimensions. The sealing structure includes a sealing member that can be elastically deformed to conform to the container opening, ensuring reliable sealing through controlled elastic deformation rather than relying solely on precise dimensional matching.
Solution Approach 2:
The sealing structure utilizes composite design combining rigid components (adapter body, sealing chamber) with elastic components (sealing member). This composite approach allows the sealing member to deform elastically under compression to create a reliable seal, compensating for variations in manufacturing tolerances and ensuring consistent sealing performance.
3Device complexity
If the medication agent passes through the adapter with spraying force only, then the device structure is simple, but most of the agent remains in the adapter and cannot be applied effectively
Solution Approach 1:
The invention extracts the medication delivery function from the simple adapter structure and implements it in a separate, removable spray solution container. The container is designed to be received in the adapter's receiving chamber, where it can be properly positioned and sealed. This extraction allows the medication to be delivered effectively through the ventilator circuit while keeping the adapter structure relatively simple.
Solution Approach 2:
The spray solution container acts as an intermediary device between the adapter and the medication delivery system. It receives the medication agent, positions it properly for spraying, and allows the ventilator airflow to carry the medication effectively to the patient, solving the problem of medication remaining in the adapter.
4Adaptability or versatility
If repeated administration causes frequent disconnection and reconnection, then different medications can be administered, but the ventilator circuit cannot maintain seal-tightening causing alveolar collapse and shear force injury
Solution Approach 1:
The system segments the medication delivery function into a removable spray solution container that interfaces with the ventilator circuit through a sealed T-shaped adapter. This segmentation allows different medications to be administered by simply replacing the container while maintaining the integrity of the main ventilator circuit, preventing seal failures and alveolar injury.
Solution Approach 2:
The adapter includes a pre-designed sealing structure and receiving chamber that are prepared in advance to receive and seal various spray solution containers. This preliminary preparation allows different medications to be administered without compromising circuit integrity, as the sealing mechanism is already in place and ready to maintain airtight connections.
