New low-cost and high-efficiency emergency ventilator comes out

  Science and Technology Daily, Beijing, April 22 (Reporter Liu Xia) According to the official website of the Imperial College London on the 21st, the school's biological engineers and doctors designed a new low-cost, high-efficiency emergency ventilator JamVent. The researchers said that JamVent does not require special parts for medical facilities, and ordinary parts can be manufactured. More importantly, it can also perform the key functions of the ICU ventilator for the treatment of patients with new coronary pneumonia. Play an important role.

  The main parts of JamVent include two pressure sensors, four on / off solenoid valves and a two-liter airtight container. The research team tested the ventilator prototype and proved that it met the standards set by the British Medicines and Health Products Authority (MHRA). In addition, it can also perform key functions of the ICU ventilator for patients with new coronary pneumonia, including clinicians' preferred "pressure-regulated volume control" mode, namely the ability to maintain pressure during inhalation, and help patients cut off spontaneous ventilation The breathing mode, and the lack of spontaneous mode and the inability to handle suction are two of the criticisms of current common ventilator designs.

  The JamVent project was initiated by the school ’s Dr. Jacob Massi-Lee. When he treated the patients with new coronary pneumonia at the Royal Brompton Hospital, he realized that there was an urgent need for a large number of ventilators in the world. Then he contacted researchers from the same school ’s bioengineering department , Jointly developed this ventilator.

  Dr. Joseph Sherwood, one of the project leaders and the school ’s bioengineering department, said: "Our goal is to use simple components outside the medical supply chain to produce a device that can perform all the key functions of the ICU ventilator. We did it. The new ventilator can be manufactured using off-the-shelf low-cost parts, avoiding supply chain bottlenecks and allowing us to increase production quickly. "

  The research team is currently working with British manufacturers and teams in the United States, Australia, and South America. It plans to produce prototype assembly lines in early May and will seek approval from regulatory agencies such as MHRA, the U.S. Food and Drug Administration to help the world better Respond to the new coronary pneumonia epidemic.

  The researchers said that there is a huge demand for ventilators in all parts of the world, especially in developing countries, and hopes that JamVent will "show its talents". It is reported that manufacturers and medical service organizations around the world can download this design for free.
