Description

Portable Respirator {AIR RESPIRATOR}

The present invention relates to a portable respirator, and more specifically, it has been developed as a general-purpose device by adding various uses and functions as a portable respirator in an emergency, especially in a fire.

In general, a portable respirator is a device used when oxygen is required for a patient or a worker in a harsh environment, and a general person who wants to maintain health due to modern serious pollution. There is a portable and beach use. The device is equipped with an inhalation device such as an oxygen supply mask or cannula-nose which is designed to dilute and breathe with atmospheric air.

However, the device has always been exposed to the risk of explosion and fire by the high concentration (99% oxygen) of the air, non-insulating body, high-pressure charging method. In addition, when breathing only high-purity oxygen, it is fatal to the human body, so it has a problem of diluting with air in the air. Therefore, it is inadequate as a safety protection function and an emergency breathing apparatus in case of fire. In addition, the gas supply source is difficult to be easily distributed, not easy to carry, and expensive, making it difficult to be generalized.

In addition, it was not easy to breathe without a separate movement only by the breather's breathing and could not perform hands free. In case of fire, there is no lantern or emergency call function in case of power failure, there is no equipment to protect the individual's respiratory system in case of fire or emergency, and the gas mask is difficult to use for more than 5 minutes at the fire site. Wearing a gas mask requires attention at the fire site.

The present invention was devised in view of the above problems, and equipped with a stainless steel sealing film in conjunction with an elastic restoring spring to facilitate recharging of the air source [cylinder], and to remove the explosion hazard when combined with the air source [cylinder]. Insulation member was used. At the site of fire, polluted air is diluted and filled with oxygen concentration below 40% to breathe with only air from the air source [cylinder].

In order to detect the inhalation pressure of the respirator, air flow control method is adopted by the elastic restoring spring in connection with the silicon membrane, and the ceramic sintered filter is coated for safe decompression and filtration.

It is designed and installed to drive emergency lantern in case of power failure in case of fire. In addition, in case of danger, the built-in rescue signal is designed to be operated by switch operation so that it can be used for self-defense. In addition, it is possible to attach a necklace or a fixing device band for easy carrying and storage.

The mask of the hands-free automatic ventilator system that can be used for breathing alone can be fitted with a refill filter after removing the gas mask, the armband, the head strap, the hose connection and the body separation.
