NO Delivery Display With Preset Starting Dose Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing NO delivery devices face errors in setting the initial dose due to urgent medical situations, leading to potential overdoses or underdoses, which can be harmful to patients.
Innovation Solution
An NO supply apparatus that displays a pre-set, non-zero starting dose upon startup, eliminating the need for manual entry and reducing errors by using microprocessor-controlled valve means and a graphic display to manage the NO flow rate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If healthcare staff manually set the NO dose at the beginning of treatment, then the dose can be adjusted according to patient needs, but errors in setting the dose occur due to urgent situations
Solution Approach 1:
The system performs preliminary action by pre-setting the initial NO dose in memory before the actual treatment begins. The microprocessor automatically displays this pre-set dose upon device startup, eliminating the need for manual entry during urgent situations and preventing dosage errors while maintaining adaptability through subsequent adjustable settings.
2Reliability
If the device displays a default pre-set dose upon startup, then dosage errors are reduced, but the device complexity increases due to memory and control requirements
Solution Approach 1:
The system implements self-service by automatically displaying the pre-set dose from memory upon startup without requiring manual intervention. The microprocessor and memory components work autonomously to present the correct initial dose, reducing the operational burden on healthcare staff while the added complexity is offset by the significant improvement in dosage accuracy and patient safety.

AI summary
The invention relates to a device for supplying (1) a gas containing NO, comprising at least one internal passage (6) with valve means (7) for conveying a flow of NO-containing gas, a graphic display (4), and microprocessor-controlled (9) control means (8) cooperating at least with the valve means to control the gas supply. Storage means (70) are provided for storing a predetermined non-zero dose of NO (NOmem) corresponding to a so-called starting NO concentration to be administered by inhalation to a patient at the start of inhaled NO treatment. The control means are configured to command, before any start of inhaled NO treatment, a default display (71) on the graphic display of the predetermined NO dose that has been stored.
