Abstract

The invention discloses a convenient underground breathing apparatus. The underground breathing apparatus comprises a backrest, winding devices are arranged in the middle of the surface of one side ofthe backrest, straps are wound around the winding devices, clamping blocks are fixedly arranged at one ends of the straps through screws, clamping grooves are formed below the winding devices, the clamping grooves are fixedly connected with the backrest through welding, a storage bag is arranged on the surface of the other side of the backrest, and the storage bag is fixedly connected with the backrest through screws. According to the convenient underground breathing apparatus, the structure is scientific and reasonable, and use is safe and convenient; the storage bag is arranged on the backof the breathing apparatus, belt clamping strips and belt clamping grooves are arranged in the storage bag, furthermore, zipper teeth and a slider are arranged outside the storage bag, and therefore an oxygen tank can be detached and installed by people in a very simple manner; moreover, oxygen tanks with different specifications can be installed in the breathing apparatus so that requirements ofthe people can be met to the maximum degree; and the winding devices are arranged on the surface of the backrest.

Description

Technical field [0001] The invention belongs to the technical field of respirators, and specifically relates to a portable downhole respirator. Background technique [0002] When the breathing device ventilates spontaneously, the inhalation action generates negative pressure in the chest cavity, and the negative pressure of the alveoli and airway occurs when the lung is passively expanded, which constitutes the pressure difference between the airway orifice and the alveoli to complete the inhalation; after inhalation, the thorax and lung elastically retract. The opposite pressure difference is generated to complete the exhalation. Respiratory equipment for treatment is often used for patients with more complex and severe illnesses. The breathing device requires more complete functions and can perform various breathing modes to meet the needs of changing conditions. Anesthesia breathing equipment is mainly used for patients undergoing anesthesia surgery. Most of the patients have...
