Researchers from the UK created a cheap analogue of the device for artificial ventilation of the lungs (IVL). Description of its new development Scientists submitted in the journal Frontiers in Medical Technology.
Development is designed to conduct sipap-therapy – artificial ventilation of lungs by constant positive air pressure, helps breathe patients with medium and severe COVID-19.
Typically, the electric fan in the device is connected to the so-called respiratory circuit consisting of a face mask, a filter controlling the flow of oxygen in the valve and tube for exhalation. The device is able to create four different levels of air pressure depending on the needs of the patient.
During the tests on healthy volunteers, the device successfully maintained the necessary level of blood saturation oxygen (from 96 to 100 percent), without causing hypoxia or hypercapnia – oversupply carbon dioxide.
The components of the prototype in the amount cost about 150 pounds sterling (approximately 15 thousand rubles) at the average cost of sipap-600 pounds sterling (about 61 thousand rubles). The developers emphasize that the device is designed for countries with low and medium income per capita. It is also designed to work with oxygen concentrators. His clinical trials pass in Uganda.
