Solution Overview
Problem
Healthcare professionals face challenges in quickly determining the autonomy of gas containers with varying gas capacities and flows, leading to tedious calculations and potential errors when selecting the appropriate cylinder for patient treatment.
Innovation Solution
A gas container equipped with a digital activation selection component that, when activated successively, displays various selectable gas flow values and corresponding autonomies, allowing users to scroll through flow/autonomy pairs without manual calculations, using a pressure sensor and signal processing means to determine autonomy based on pressure signals and selected flows.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the user manually activates the flow selector and waits for autonomy display on each cylinder, then the autonomy information can be obtained, but the process is time-consuming and tedious
Solution Approach 1:
The electronic device pre-calculates and stores autonomy values for multiple flow rates before the user needs them. When the user activates the selection component, the device immediately retrieves and displays the corresponding autonomy information without requiring manual flow selector activation or real-time calculations, thus resolving the contradiction between obtaining complete autonomy information and minimizing selection time.
Solution Approach 2:
The device creates a digital copy of autonomy information for all possible flow rates and displays it on demand. Instead of requiring the user to physically adjust the flow selector and wait for display updates, the system generates virtual representations of autonomy data for all flow options and makes them instantly accessible through the selection component, eliminating time loss while preserving complete information.
2Quantity of substance
If the electronic device displays remaining gas in litres, then the gas quantity is provided, but the operating duration cannot be known without manual calculation
Solution Approach 1:
The system transforms the displayed parameter from static gas quantity (litres) to dynamic autonomy information (time) by pre-calculating operating duration for each flow rate. The selection component allows users to switch between different flow rate scenarios, and the device automatically updates the displayed autonomy time accordingly, eliminating the need for manual calculations while preserving accurate gas quantity information.
Solution Approach 2:
The selection component acts as an intermediary that translates between flow rate choices and autonomy information. Instead of requiring users to perform calculations to convert gas quantity to operating duration, the selection component mediates this transformation by automatically computing and displaying the corresponding autonomy time for each selected flow rate, simplifying the user interaction while maintaining accuracy.
3Adaptability or versatility
If multiple cylinders are stored in a depot or response vehicle, then availability is ensured, but the user must evaluate each cylinder individually to select the appropriate one
Solution Approach 1:
The electronic device with selection component provides a universal interface for evaluating multiple cylinders regardless of their individual characteristics. The selection component allows users to systematically compare autonomy information across different flow rates for each cylinder in the storage location, simplifying the evaluation process while maintaining the ability to handle diverse cylinder types and capacities.

AI summary
The invention relates to a gas container equipped with a gas distribution valve having an electronic device for measuring gas autonomy. Flow selection means allow a desired gas flow to be selected. The electronic device includes a pressure sensor. Signal processing means allow gas autonomies to be determined on the basis of the pressure signal and of the selectable gas flows. A selection component cooperates with the signal processing means in order to successively display, on data display means and in response to successive digital activations by the user of the selection component, the various selectable flow values and the various corresponding autonomies, with each flow value being simultaneously displayed with a corresponding autonomy.
