The invention discloses a two-way closed-loop automatic switching device. The device comprises a first oxygen channel, a second oxygen channel, an output and oxygen supply channel, a first auxiliary channel and a second auxiliary channel. An air outlet of the first oxygen channel is connected with a first air inlet of the output and oxygen supply channel, an air outlet of the second oxygen channel is connected with a second air inlet of the output and oxygen supply channel, one end of the first auxiliary channel and one end of the second auxiliary channel are vertically connected with the output and oxygen supply channel, the other end of the first auxiliary channel and the other end of the second auxiliary channel are vertically connected with the first oxygen channel and the second oxygen channel respectively, an air inlet of the first oxygen channel is connected with an oxygen tank of an oxygen generator, and an air inlet of the second oxygen channel is connected with a bus-bar. By means of the two-way closed-loop automatic switching device, oxygen can still be continuously supplied under the situation that an oxygen generator system breaks down or power failure happens.
Description
technical field [0001] The invention belongs to the field of medical equipment, in particular to a bidirectional closed-loop automatic switching device. Background technique [0002] With the improvement of people's living standards, the requirements for quality of life are also increasing reasonably. The improvement of air requirements is part of the reasonable improvement of people's quality of life. In modern life, while people improve their living and working environment, it is easy to form a closed and hypoxic environment that can be seen everywhere, such as air-conditioned rooms, closed cars, gyms, bars, karaoke halls, office spaces, classrooms, etc. Personnel engaged in mental work, such as company employees and students, are particularly prone to hypoxic symptoms in the above-mentioned airtight hypoxic environment, resulting in problems such as low work efficiency and low learning efficiency. Patients who also suffer from respiratory diseases, such as asthma, trach...
