Chemical oxygen self-rescuer for quick change of medicine tank

Abstract

The invention discloses a chemical oxygen self-rescuer for rapidly changing medicine tanks, belonging to the technical field of self-rescuers. The invention includes a breathing circulation system and two circulation pipes and is equipped with a control device for rapidly changing the medicine tank; The breathing circulatory system includes an air outlet, an air inlet pipe and a three-way pipe, the lower end of the air outlet is connected to the circulation pipe interface of one of the circulation pipes through a pipe interface, and the lower end of the air intake pipe is connected to the circulation pipe of the other circulation pipe through the pipe interface. On the interface; there is a replaceable medicine tank on both sides of the breathing circulatory system, and the lower end of the replaceable medicine tank has two medicine tank insertion ports; the replaceable medicine tank is simultaneously sealed and connected to the two On the tank port on the same side of the circulation tube. The invention has simple structure and convenient use, can quickly replace the chemical oxygen self-rescuer medicine tank, and realize the rational storage and use of the medicine tank.

Description

technical field [0001] The invention relates to a chemical oxygen self-rescuer, belonging to the technical field of emergency rescue equipment. Background technique [0002] At present, in high-risk operating environments such as mines, self-rescuers are a common and necessary emergency rescue equipment, which can provide oxygen support in emergency situations and provide protection for the human respiratory system. In the event of a disaster accident, there will be situations such as hypoxia or poisonous gas leakage due to fire and explosion that seriously endanger life and safety. In this scenario, you must first wear a self-rescuer to protect your life, health and safety. [0003] Existing self-rescuers can be divided into two categories according to their technical principles, compressed oxygen self-rescuers and chemical oxygen self-rescuers. Compressed oxygen self-rescuers can directly store oxygen, and can be recharged with oxygen for recycling after cleaning and ster...

Problems solved by technology

However, its disadvantages are large volume and heavy weight. The compressed oxygen self-rescuer tank itself needs to be made of high-density materials, and the compressed oxygen self-rescuer that can be stored for use for more than 30 minutes is often heavy. In addition, the commonly used isolated layout needs to arrange absorption drugs. The compressed oxygen self-rescuer is bulky and heavy, and the capsule is exposed and small, causing inconvenience to the user to wear and move

The chemical oxygen self-rescuer has the advantages of light weight and small volume. However, the current chemical oxygen self-rescuer has a relatively short service life and is discarded after one-time use.

There are already Chinese patents CN207168850U and CN205516052U that have innovated on replaceable medicine tanks, but the replacement interface is relatively complicated, the replacement process is relatively cumbersome, and safety is not easy to guarantee, and it cannot handle the storage of spare medicine tanks well and judge the replacement of medicine tanks.
