    ITS Creates E-VITS, a Ventilator for Covid-19 Patients

    ITS Surabaya is continuously involved in finding solutions amid the Covid-19 pandemic. One of the solutions is to make a simple and low-cost mechanical ventilator innovation called E-VITS (Emergency Ventilator ITS). Since March 24, the E-VITS innovation team has been struggling in making prototype emergency ventilators. The first version of the E-VITS prototype was launched on April 7 at ITS Robotics Building. After that, the team continues to develop to achieve the standardization from Health Facilities Safety Center (BPFK) Surabaya.

    E-VITS is a prototype of a simple and low-cost mechanical ventilator developed by the Ventilator Team of the Department of Physics Engineering, ITS. Since May 5, tests on E-VITS have been conducted to ensure that the ventilator system meets the standard required by BPFK. Finally, on Thursday, May 21, it was declared that the E-VITS has fulfilled a ventilator’s performance standards by BPFK. The tool will be prepared for clinical testing for the next step.

    Dr. Aulia Muhammad Taufiq Nasution, the head of the Ventilator Team, explained that E-VITS prototype has been improved from the initial version that was launched on April 7. The improvement of the ventilator prototype is emphasized on the system operational resilience. Some improvements were made to produce the stability and accuracy of the performance.

    Dr. Aulia mentioned that the five standards required by BPFK are electrical safety test, visual test, endurance test, performance test, and the availability of documentation related to the technical, operational, and maintenance of the ventilator. Therefore, the team made a thorough internal test to ensure that E-VITS meets all five requirement aspects. An important point of the five aspects is ventilator endurance. For this matter, the reliability test has been performed by operating the device for 2×24 hours non-stop. The objective is to monitor whether the ventilator system can produce a stable performance in accordance with the required standard. The system is considered stable if it can maintain the accuracy and precision of the performance.

    BPFK test results showed that the E-VITS received satisfactory performance for all required aspects. A minor improvement was recorded by BPFK for the next phase of clinical test. The next clinical test will deal with the dimension of the device and the improvement of labeling quality on E-VITS casing. Later, the E-VITS will be designed with a slimmer dimension.
