Unitronics PLC in Slovenian medical respirator
Due to the crisis posed to the world by the COVID-19 virus, the partners of the project for the development of the Slovenian medical respirator “DIHAM” joined forces and in a very short time developed a prototype of a respirator to save lives. They have developed a medical respirator that will be able to be completely self-sufficiently produced in Slovenia with Slovenian knowledge and components. Among other things, they also used our Unitronics Unistream PLC controller in the respirator.
The principle of operation of the DIHAM respirator
We respectfully announce that the companies Domel , Lotrič Meroslovje , Zavod 404 , Tehnološki park Ljubljana , EKWB and the company BPMC participated in the project . The first four companies are also our valued partners. To describe the operation of the DIHAM respirator, it is best to quote the manufacturers.
It is a so-called turbine pressure respirator (without inflatable bellows), intended for the most critical patients, with severely damaged lungs who can no longer breathe on their own and need a medically adapted dosage of a mixture of air and oxygen. The device is designed in such a way that it can operate in a hospital environment as well as in mobile hospitals or even independently.
The core of the device is a blower motor, and the device independently provides its own source of pressure and air flow, which means that it does not need compressed air. The device is independent of other sources if it is provided with only an electrical network and an oxygen source, which can be central or from a gas bottle with oxygen. The regulation of the device allows adjustment according to the patient’s condition and to the instructions of the medical staff. SOURCE

3 different modes of operation
- The first method is “Double Pressure or BIPAP”. It is characterized by the device ‘breathing’ instead of the patient when he is unconscious or in a coma.
- “CPAP”, in this case the device waits for the patient’s breath via a mask or tube, the so-called “trigger” or trigger signal. The patient is conscious and breathes independently with the help of a respirator. The respiratory rate is dictated by the patient, and the respirator helps breathing to the patient.
- The last way is “High flow”. The oxygen-enriched air flow travels through the tubes to the patient’s nose, thus providing the patient with sufficient flow and oxygen during independent breathing.
