Automatic simple respirator for field emergency treatment

Abstract

The invention discloses an automatic simple respirator for field emergency treatment. The automatic simple respirator comprises a mask, an elastic belt, a compression air bag, a switch button, a tidalvolume gear button, a rechargeable battery, an MCU module, an electric three-way T-shaped ball valve, a miniature air suction pump, a flow monitoring device and a filtering device. According to the invention, power is supplied through a rechargeable battery only by toughing a switch button and setting the gears of the tidal volume, the electric three-way T-shaped ball valve is driven to work, anair inlet and an air outlet of the electric three-way T-shaped ball valve are circularly opened through an MCU module setting program, when the air inlet is opened, the miniature air suction pump is triggered to operate, so that air enters the compression air bag, the air inlet is provided with a flow monitoring device and a filtering device, and when the set tidal volume is reached, the air inletis closed and the air outlet gas enters the mask through the gas outlet, the electric three-way T-shaped ball valve operates at the frequency of 16 times per minute, sufficient per-minute ventilationis guaranteed, automatic auxiliary ventilation is achieved, the automatic simple respirator is simple in operation, small in volume and convenient to carry and suitable for battlefield emergency treatment.

Description

technical field [0001] The invention relates to a medical device, in particular to an automatic simple respirator for field first aid. Background technique [0002] Simple respirator is a commonly used first aid device in clinical practice. It is a simple and effective artificial respiration device. In an emergency, it can provide lung ventilation for patients with sudden dyspnea or respiratory failure, so as to maintain and increase the ventilation of the body. [0003] The existing commonly used simple respirator is generally composed of a balloon, an inlet check valve, an outlet check valve, an exhalation valve, and a mask. Artificial respiration is achieved by manually squeezing the balloon. Although the operation is simple, it requires Artificially continuously extruding the balloon to provide ventilation, and at the same time need to artificially fix the mask, and sufficient manpower is needed in the first aid process. If there are many wounded on the battlefield and t...

[0003] The existing commonly used simple respirator is generally composed of a balloon, an inlet check valve, an outlet check valve, an exhalation valve, and a mask. Artificial respiration is achieved by manually squeezing the balloon. Although the operation is simple, it requires Artificially continuously extruding the balloon to provide ventilation, and at the same time need to artificially fix the mask, and sufficient manpower is needed in the first aid process. If there are many wounded on the battlefield and the rescue personnel are in short supply, the existing simple respirator is obviously not suitable, so It is of great application value to develop a simple respirator with automatic ventilation function, a mask with a fixing device, and a small and easy-to-carry respirator
