Electric extrusion device of breathing bag

Abstract

The invention discloses an electric extrusion device of a breathing bag. The extrusion device is fixed on the periphery of the breathing bag through an upper fixing block and a lower fixing block. The extrusion device comprises two mechanical arms which are symmetrically arranged on the two sides of the breathing bag and driven by a stepping motor. The two mechanical arms are both fixed to the upper fixing block through rotary shafts. The stepping motor simultaneously controls extrusion and expansion actions of the two mechanical arms through a gear rotating coaxially with the stepping motor. An upper rack and a lower rack which perform transmission in cooperation with the gear and opposite in transmission direction are arranged at the upper end and the lower end of the gear respectively. The end portion of the upper rack and the end portion of the lower rack are hinged to the end portions of the two mechanical arms through transmission rods, and the other end of each mechanical arm is provided with a manipulator matched with the peripheral face of the breathing bag in shape. The electric extrusion device of the breathing bag can replace human hands to press the breathing bag, is small in size and convenient to carry and facilitates implement of first-aid work. The mechanical operation can ensure the frequency of oxygen supply and stability of tidal volume, and thus quality of the first aid for a patient is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an electric extruding device for a breathing airbag. Background technique [0002] At present, in the first aid and transfer process of patients with spontaneous breathing difficulties in hospitals, breathing airbags are widely used as temporary ventilation equipment to assist patients in breathing. When in use, connect the outlet end of the breathing airbag to the breathing mask or the tracheal intubation tube, squeeze the breathing airbag by hand, and blow the gas in the bag into the patient's lungs. When the breathing bag is released, the patient's lungs passively contract to "exhale" the air in the lungs. Due to the guiding effect of the one-way valve, the exhaled gas can only be discharged into the atmosphere through the valve. There is elastic plastic in the breathing bag, which can automatically inflate when it is not pressurized and suck in fresh air from anothe...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to overcome, on the one hand, the problems in the prior art that it is difficult for medical personnel to maintain accurate air supply volume and tidal volume due to manual pressing of the breathing air bag when facing t...
