LETI has developed a device to normalize the diaphragm after lung diseases

The device uses electrical impulses to stimulate the diaphragm and to restore the lung function of the patients recovering from grave diseases.

Diaphragm is an important muscle in a human body which among other things ensures a specific process in the respiratory system (breathing in and out), helping the lungs to perform their function.

As a result of different infections, e.g. coronavirus infection, the lungs tissue might suffer pathological changes and the diaphragm might not function correctly. This is why doctors pay significant attention to restoring and strengthening the diaphragm of a convalescent.

“We have developed a compact device which stimulates the phrenic nerve with electrical impulses normalizing the diaphragm function. It is well known that there is a method to stimulate muscles with implanted current electrodes which facilitates their recovery after injuries and illnesses. Our device works in a similar manner but in a totally non-invasive way”.

A prototype of the device to restore the diaphragm function consists of a programmed current source and a complex of special non-invasive electrodes. The therapeutic effect occurs when the phrenic nerve area is briefly affected by specifically chosen electrical signals.

“This device allows us to stimulate the respiratory activity of a patient who has suffered a disease which affected their lungs. Today this might be useful for those, for example, who are trying to regain their health after suffering coronavirus”.

Now the LETI scientists are working together with the Director of the Laboratory of Anesthesiology and Intensive Care with Clinic of the Almazov Medical Research Centre, Professor Vadim A. Mazurok, to test the device.

The project is a part of the large interdisciplinary course of work of the scientists of the Department of Electronic Instruments and Devices of LETI. It is concentrated on the development of cutting-edge medical equipment and methods of its exploitation. For example, supported by the EuroVenture Foundation, the LETI scientists have built an X-ray machine which allows doctors to find out quickly and precisely whether the tumour was removed completely in the process of an operation on the mammary gland tissue. This is the first X-ray machine of this type in Russia. The registration certificate for the machine is now being executed. Besides, researchers at LETI continue their study to develop specialized equipment for radiation and photodynamic cancer therapy.
