Novel rotary pressing type simple breathing device

Abstract

The invention provides a novel rotary pressing type simple breathing device, and relates to the technical field of medical instruments. The novel rotary pressing type simple breathing device comprises a gas cylinder, a movable plate and a gas flow detector, wherein an assembling opening is formed in the outer side of the gas cylinder, and a gas inlet valve set is installed in the assembling opening; the movable plate is located inside the gas cylinder, and the movable plate is connected with a crankshaft through a connecting rod; and the gas flow detector is connected to the outer side of the gas cylinder. According to the novel rotary pressing type simple breathing device, a rocking handle is rotated to drive the crankshaft to rotate in a reciprocating mode, so that the connecting rod connected with the crankshaft drives the movable plate inside the gas cylinder to move up and down in a reciprocating mode, the movable plate extrudes oxygen inside the gas cylinder into an oxygen mask, so that continuous conveying operation of the oxygen is realized, the operation is simpler, and the physical consumption of medical staff is reduced; and the connecting part of an adjusting bolt and a limiting screw hole in the outer side of the gas cylinder is changed, the adjusting bolt limits the rotating angle of a movable limiting rod, the rotating angle of the crankshaft is limited, so that the up-down moving distance of the movable plate is limited, and the effect of controlling the tidal volume is achieved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and more specifically relates to a novel spinning type simple breathing device. Background technique [0002] The simple respirator, also known as the resuscitation ball, is suitable for cardiopulmonary resuscitation and occasions requiring artificial respiration first aid, especially for suffocation, dyspnea or the need to increase oxygen supply. It is easy to use, less painful, fewer complications, and convenient It is portable and can be ventilated immediately with or without an oxygen source. [0003] The simple breathing device can refer to the patent No. CN104399161B, which mainly includes a mask, an air storage bag, a balloon and an oxygen connecting tube. Its innovative point is that it also includes a negative pressure device and a sterile plastic film; , consisting of a section, b section and c section, the balloon is provided with a negative pressure opening, and a negative pr...

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides a novel spinning type simple breathing device to solve the problem that the existing similar simple breathing devices usually need to frequently press the elastic airbag with fingers to provide oxygen supply for the patient, which is harmful to the human hand. Muscle group damage is relatively large, and long-term pressing operations are likely to cause hand cramps and affect the subsequent oxygen delivery effect
