Flow-self-adjusting oxygen delivery device for respiratory medicine nursing

Abstract

The invention discloses a flow self-adjusting oxygen delivery device for respiratory medicine nursing, which comprises an oxygen tank and an oxygen supply mask, a flexible pipeline is arranged between the oxygen tank and the oxygen supply mask, the lower side of the oxygen supply mask is fixedly provided with a fixing rope, the flexible pipeline is internally provided with a flow assembly, and the flow assembly is fixedly connected with the oxygen supply mask. A concentration assembly is arranged in the oxygen supply mask, the flow assembly comprises flow cylinders, the flow cylinders are evenly arranged in a flexible pipeline, flow rods are slidably connected into the flow cylinders, annular pipelines are fixedly installed at the positions, located on the upper sides of the flow rods, in the flow cylinders, and the annular pipelines are connected through pipelines. One side of the annular pipeline is in pipeline connection with a first flexible ball, the first flexible ball is fixedly installed above the oxygen supply mask, the concentration assembly comprises a density ball, and the intelligent oxygen supply mask has the advantages that the oxygen flow can be intelligently adjusted and controlled, and the oxygen concentration can be automatically adjusted.

Description

technical field [0001] The invention relates to the technical field of oxygen delivery, in particular to an oxygen delivery device for respiratory internal medicine nursing with flow self-regulation. Background technique [0002] In the face of patients with severe pneumonia, an oxygen delivery device is essential, and the existing breathing masks can effectively separate the exhaled gas from the input gas to avoid contamination of the gas. [0003] And the existing oxygen delivery device, the utilization rate of oxygen is low, because the adjusting method of oxygen flow is not very accurate and has bigger subjectivity, causes a large amount of oxygen wastes or can't reach very good breathing effect, and existing oxygen delivery device Lack of a control device for oxygen concentration, when worn for a long time, will cause irreversible damage to the patient due to oxygen toxicity. [0004] Therefore, it is necessary to design a flow self-regulating oxygen delivery device fo...
