Simple respirator

Abstract

The invention relates to the field of medical equipment, in particular to a simple respirator which comprises a balloon, a disposable sterile plastic film, a getter device, a gas discharging one-way valve, an air sending device and a mask. The simple respirator is characterized in that one end of the balloon is connected with a reservoir bag through the getter device, the other end of the balloon is connected with the mask through the air sending device, the gas discharging one-way valve is installed on one side of the balloon, the disposable sterile plastic film is installed on the inner side of the balloon, and the two ends of the disposable sterile plastic film are connected with the getter device and the air sending device respectively. The simple respirator has the advantages that the simple respirator is simple and ingenious in design and convenient to use; the disposable sterile plastic film is adopted, the respirator is internally subjected to pollution easily and easy to sterilize, there is hardly any corrosion damage to the balloon, and the service life of the respirator is prolonged. The respirator can be used outdoors, a vacuum extractor is not needed, and the respirator is simple to operate. Besides, the use requirements for the whole respirator are lowered, and the applied range is wide.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a simple respirator. Background technique [0002] The simple respirator is the simplest artificial respiration device pressurized by equipment, which is suitable for occasions where artificial respiration is required for cardiopulmonary resuscitation (CPR) and during patient transportation, especially in various situations where suffocation is difficult to breathe or oxygen needs to be provided. Ventilator-associated lower respiratory infection (VALAI) is a common complication in mechanically ventilated patients, and the migration of pathogenic bacteria on the balloon is one of the important causes of VALAI . . Mechanically ventilated patients are affected by power outages, ventilator circuit replacement, and chest physical therapy such as regular lung expansion during daily care. They all need to use simple artificial respirators. and the pollution of the surrounding environm...

Problems solved by technology

Although some tertiary hospitals clean and disinfect simple respirators, it is difficult for my country's huge county-level hospitals; my country's health authorities should attach great importance to this

Our hospital is very strict on the cleaning and disinfection of simple respirators. I found in practice that this not only increases the workload of clinical nurses, but also causes corrosion to the structure of simple respirators; especially the balloons of simple respirators contain chlorine for a long time Reagent disinfection, plastic balloon aging, surface stickiness

At the same time, it is difficult to dry the wet simple respirator parts after disinfection. When exposed to the air for a long time, bacteria and unknown substances are easy to adhere to it, reducing the disinfection effect, so it is urgent to improve
