Oxygen-filtering breathing apparatus for emergency internal medicine department

Abstract

The invention discloses oxygen-filtering breathing apparatus for the emergency internal medicine department. The oxygen-filtering breathing apparatus comprises an oxygen tank; the oxygen tank is provided with an air pressure regulating structure; the oxygen tank is provided with a first connecting tube; the first connecting tube is connected with the interior of a filter in an inserted manner; thefilter is connected with a second connecting tube; the second connecting tube is connected with a mask; the first connecting tube is provided with a first flow control valve; the second connecting tube is provided with a second flow control valve; a liquid level monitoring mechanism is arranged in the filter; the liquid level monitoring mechanism is provided with paired metal sheets; the filter is provided with a buzzer; the buzzer is connected with a storage battery; and the paired metal sheets are connected onto a buzzer circuit in series. By installing the air pressure regulating structureon the oxygen tank, the situation that the oxygen tank is in a constant pressure state can be guaranteed, so that the oxygen tank keeps a constant air outlet state, and the comfort of a patient during use of the oxygen filtering breathing apparatus is enhanced.

Description

Technical field [0001] The invention belongs to the technical field of medical equipment and equipment, and in particular relates to an oxygen-filtered breathing apparatus for emergency medicine. Background technique [0002] Emergency medical patients have difficulty breathing and usually need to use a ventilator to assist the patient to recover from treatment. The breathing device separates the human respiratory system from the outside world. The instrument and the human respiratory system form an internal circulation, and the high-pressure gas cylinder provides oxygen. The existing breathing apparatus, when used by a patient, first adjusts the gas output volume and the oxygen gas output rate of the oxygen cylinder according to the patient's breathing frequency. Since the air pressure in the oxygen cylinder decreases with the decrease of oxygen, the corresponding air output is also gradually reduced, resulting in a different oxygen supply rate. The patient has to adjust multipl...

AI Technical Summary

Problems solved by technology

Since the air pressure in the oxygen cylinder decreases with the decrease of oxygen, the corresponding air output is also gradually reduced, resulting in different oxygen supply rates. Patients need to make multiple adjustments to adapt to their own breathing frequency, and the use process is cumbersome.

And in the process of using, when the liquid in the filter is used up, people cannot be prompted to replenish the liquid in time, which brings great inconvenience to the use of the patient.
