Breathing apparatus controlled through breath

Abstract

The invention discloses a breathing apparatus controlled through breath. The breathing apparatus comprises a face mask and a breathing control connector. A gas inlet connector of the face mask is connected with the breathing control connector through threads. A partition plate integrally formed together with the breathing control connector is arranged in the middle of an inner cavity of the breathing control connector. A plurality of vent holes are formed in the surface of the partition plate. Electromagnetic valves are arranged in the vent holes. A gas pressure sensor and a humidity sensor are arranged on the inner surface of the face mask. A gas flow sensor is arranged on the inner wall of the gas inlet connector of the face mask. According to the breathing apparatus, the oxygen requiring situations of patients are identified through the gas pressure sensor and the humidity sensor on the inner surface of the face mask, the opening and closing number of the electromagnetic valves in the vent holes in the partition plate is controlled through a breathing controller, and therefore the oxygen circulation amount of the breathing apparatus is controlled in this way, the oxygen requirement amounts of patients at each stage are ensured, and anoxia caused to patients when the breathing apparatus is not regulated in time is prevented.

Description

technical field [0001] The invention relates to the technical field of breathing apparatus, in particular to a breathing apparatus controlled by breathing. Background technique [0002] During the spontaneous ventilation of the breathing device, the inspiratory action generates chest negative pressure, and the passive expansion of the lungs produces alveolar and airway negative pressure, thereby forming a pressure difference between the airway opening and the alveoli to complete inhalation; after inhalation, the thorax and lungs elastically retract, The opposite pressure difference is generated to complete the exhalation; the respiratory equipment for treatment is often used for patients with complicated and serious conditions. The oxygen flow rate of the device can only be adjusted manually, and the amount of oxygen consumed by patients with complex and serious illnesses is also different at different time periods. If the oxygen flow rate of the breathing device is not adju...

[0002] During the spontaneous ventilation of the breathing device, the inspiratory action generates chest negative pressure, and the passive expansion of the lungs produces alveolar and airway negative pressure, thereby forming a pressure difference between the airway opening and the alveoli to complete inhalation; after inhalation, the thorax and lungs elastically retract, The opposite pressure difference is generated to complete the exhalation; the respiratory equipment for treatment is often used for patients with complicated and serious conditions. The oxygen flow rate of the device can only be adjusted manually, and the amount of oxygen consumed by patients with complex and serious illnesses is also different at different time periods. If the oxygen flow rate of the breathing device is not adjusted in time, the patient may suffer from hypoxia situation, for this purpose, we propose a breathing apparatus controlled by breathing
