Respirator Standby Control for Low-Power Self-Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Breathing or anesthesia apparatuses have high energy consumption during standby mode and require lengthy self-tests, which can lead to increased operational burdens and risks of errors due to prolonged testing times.
Innovation Solution
Implementing a pretest before entering an energy-saving mode to ensure essential components are functioning correctly, followed by a self-test before transitioning to standby mode, with the option to schedule the self-test based on user input, and utilizing a heating means to maintain system functionality while reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a full self-test is performed before standby mode, then reliability is improved, but loss of time increases due to the 8-minute duration
Solution Approach 1:
The test procedure is divided into two distinct segments: a pre-test that checks essential components quickly, and a full self-test that performs comprehensive checks. This segmentation allows the system to achieve reliable operation with reduced time loss by performing only critical checks before standby mode.
Solution Approach 2:
A pre-test is performed as a preliminary action before the full self-test and before entering standby mode. This preliminary check identifies obvious errors early, allowing corrective actions to be taken before the more time-consuming full self-test, thereby reducing overall time loss.
2Reliability
If the heating means and processor remain on during standby mode, then reliability is improved, but use of energy increases to 70 W
Solution Approach 1:
The system dynamically adjusts the operational state of components during standby mode. The heating means and processor are switched off during standby, and the system transitions to a quick-start capability that can reactivate these components rapidly when needed, thus reducing energy consumption while maintaining operational reliability.
Solution Approach 2:
The system implements periodic self-tests at scheduled intervals rather than continuously maintaining full operational readiness. This periodic activation of the heating means and processor reduces energy consumption during standby while ensuring reliability through regular checks.
3Use of energy by moving object
If the gas delivery means is operated with low output during expiration, then use of energy is reduced, but productivity decreases
Solution Approach 1:
The gas delivery means operates at full output only during inspiration phases and is switched off or operates at minimal output during expiration phases. This periodic operation pattern reduces overall energy consumption while maintaining adequate productivity by delivering gas at full capacity when actually needed for patient ventilation.

Function Achieved in This Case
This approach significantly reduces energy usage outside operating times and minimizes the risk of errors during standby mode by ensuring all components are tested before deactivation, allowing for efficient and reliable operation with low power consumption.
Implementation Method 1
a heating means of the breathing or anesthesia apparatus is also switched on during the standby mode

AI summary
An breathing or anesthesia apparatus and a process for operating a breathing or anesthesia apparatus are provided in which only a very low energy consumption occurs outside of the operating times. The breathing or anesthesia apparatus (1) is put into an energy-saving mode and a function pretest is performed before putting the apparatus into the energy-saving mode. A function self-test is carried out when the breathing or anesthesia apparatus is put into a standby mode.
