Automation during manufacturing
Automated programs control the ventilator and calibration equipment making the process of verifying the performance and operational state of the ventilator completely automatic.
To clarify how this works, a good example is a script that performs full verification of the flow generation system, the flow sensors and the pressure sensors. This script performs the following procedures automatically and within minutes:
- Calibrates the pressure sensors using the external calibration equipment
- Runs internal calibration procedures for the exhalation flow sensor
- Runs ventilation in a range of settings and verifies the measurements of the ventilator with respect to the calibration equipment
Multiple scripts are automatically run to verify all the components of the ventilator are fully compliant with the requirements.
By doing so, the reliability of the testing process of the ventilator during and after assembly is increased while the time and costs associated with the testing are significantly reduced.
Burn in automated control and tracking
Burn-in of the ventilators is also controlled by the automation programs. These programs change the settings during the burn in process, monitor flows, pressures, volumes, temperatures and even the battery charge during battery discharging. All data is logged automatically and is correlated to the device file.
Problems can be automatically detected during the burn in to save run time and address the issue immediately. In addition, when the burn in is successful, the system generates a full report that is then added to the device file.
Tracking and updated devices in the field
The VINS inside the ventilators can communicate with our servers to report any technical anomalies in real time. It can also upload logs and information which are required for better understanding of possible reasons for the faults generated. These logs can be uploaded automatically or upon request on the ventilator’s user interface.
This automatic tracking reduces the risk that a fault in hardware or software would escalate and become a problem in the field, in the specific device or in many devices. This capability also enables tracking of faults after they have been resolved by preventive actions.
Automatic Software update and maintenance tracking
One of the challenges that all manufacturers are faced with is tracking of software updates as well as hardware maintenance and repair operations. The VINS can automatically download software updates and notify the servers when they are installed. In fact, the notification which includes the S/N of the device, date and time and name of the person which performed the update is also sent if the software update has been done using a local SD card or USB memory as well. This enables centralized tracking of the operations performed on the ventilator without the need for a technician to report this through the distribution network to the responsible authority in the company. Doing so increases the compliance with regulatory requirements addressing the tracking of operations on the device and recording them in the device file.
Automated maintenance and repair
By using the automated scripts the faulty components can be easily detected and verified once replaced. After repair scripts verify the full functionality and performance of the ventilator. This reduced the repair or maintenance time of the device, enabled reducing the training required for the person that performs these actions, increases the reliability of the operation and this leads to a reduction in the associated costs.
