AI Technical Summary

Technical Problem

The existing simple ventilators for emergency surgery have weak oxygen flow rate adjustment functions, making it difficult to adjust according to the patient's needs, and the nebulization function is insufficient, resulting in dryness and discomfort in the patient's respiratory tract.

Method used

A simple emergency surgical ventilator was designed, comprising an adjustment component and a nebulizer component. The adjustment component enables flexible adjustment of oxygen flow through the cooperation of a rotating column and a limiting rod, while the nebulizer component achieves oxygen humidification through a water pump and a nebulizer nozzle.

Benefits of technology

It enables flexible adjustment of oxygen flow to meet the needs of different patients, avoids dryness of the patient's respiratory tract, and improves the practicality and comfort of the device.

Abstract

The utility model relates to the technical field of emergency departments, in particular to a simple breathing machine for emergency surgery, which comprises a fixing plate, an oxygen bag is fixedly connected to one side of the top of the fixing plate, a connecting pipeline is communicated to the surface of the oxygen bag, and an adjusting block is fixedly connected to one end of the connecting pipeline. An adjusting assembly is fixedly connected to the top of the adjusting block and comprises an adjusting piece. Through the arrangement of the atomization assembly, during use, a worker is connected with an external water source through the water inlet, water is filled into the water tank, then the water pump is started, the water pump pumps out water in the water tank through the input pipeline, and then the water is conveyed into the atomization nozzle through the output pipeline; and the atomization nozzle performs atomization water spraying treatment on the interior of the oxygen conveying pipeline, so that oxygen is humidified, and the situation that the patient breathes for a long time, the respiratory tract is dry, and discomfort of the patient is increased is avoided.
