An insufflator is designed to pump gas into human internal cavities and automatically maintain pressure within the cavity during endoscopic surgery on internal organs. Proper operation of the insufflator is absolutely essential for patient safety and the successful completion of laparoscopic surgery. Insufficient gas supply will not create the necessary space, and an uncontrolled increase in intra-abdominal pressure above 15 mmHg can lead to disruption of the cardiovascular and pulmonary systems, leading to complications such as pneumothorax, subcutaneous emphysema, and gas embolism. Therefore, choosing an insufflator is a crucial and responsible decision. ElePS specialists have developed a domestic insufflator [https://eleps.ru/katalog/po-vidam-produktsii-oborudovanie-insufflyatory/] with a unique "voice informant" feature. The insufflator provides short and detailed voice messages in Russian about emergency situations: lack of gas at the insufflator inlet, break in the gas supply hose to the abdominal cavity, pinched gas supply hose, pressure exceeding the set value, etc.). The "speech informant" function is controlled from the device's operating panel. The main advantages of the IEE-1/30-"ElePS" insufflator: - a voice informant that informs about an error in the system; - a system of formed gas supply in case of unexpected pressure loss before reaching the set value; - an increased size of the pressure indicator in relation to other indicators; - a two-color "thermometer" type indicator of the input pressure with a color change when the required range of the input pressure is violated; - a pressure relief system when the pressure exceeds the set value; - an indication of the current gas consumption as a percentage of the set value. Main technical characteristics of the IEE-1/30-ElePS insufflator: - the IEE-1/30-ElePS insufflator is designed to pump carbon dioxide. Carbon dioxide does not support combustion, is readily available, inexpensive, and quickly dissolves in the blood, which reduces the risk of gas embolism when entering the bloodstream. - the maximum gas supply rate of 40 l/min allows for large-scale interventions and easily maintains the required space in all situations that result in significant gas leakage and require its rapid replenishment (when replacing instruments, inserting staplers, removing a drug, in case of significant bleeding, etc.); - input pressure of 0.05 MPa, - the range of supported pressures is from 1 to 30 mm Hg; - gas consumption counter in the range from 0.01 to 999 l; - input pressure indication in the range from 0 to 0.3 MPa with a resolution of 0.1 MPa, in the range from 0.3 to 0.65 MPa with a resolution of 0.05 MPa; - digital indication of the set pressure in the range from 1 to 30 mmHg; - digital indication of abdominal pressure in the range from 1 to 99 mmHg; - digital indication of the set gas flow (% of the set value) in the range from 0 to 100; - digital and sound indication of negative pressure in the range from -1 to -9 mmHg; - indication of the current gas flow as a percentage of the set value in the range from 0 to 100%; - sound alarm of vacuum in the abdominal cavity with a response level of at least minus 3 mmHg; - power consumption 45 VA. Continuous operation time is 8 hours. The outer surfaces of the device are resistant to multiple disinfection; - overall dimensions of the device are 323 x 132 x 329 mm; - weight 9 kg; - service life of 5 years; - delivery set: electronic unit, 220 V network cable, cylinder reducer, medical silicone tube with a diameter of 5x8 mm, length 3 m, fusible link, passport, technical description and operating manual.
