Description

Mouth and nose mask type self-rescuer

Technical Field

The utility model relates to a gauze mask type self-rescuer belongs to the safety device field.

Background

The oxygen self-rescuer is a portable breathing protective device which utilizes oxygen to supply oxygen for a gas source so as to prevent toxic gas poisoning or oxygen deficiency asphyxia, can rapidly provide clean oxygen for a wearer when gas or coal dust accidents and fire accidents occur, and is completely isolated from the outside ambient air in use without being harmed by any outside toxic and harmful gas and smoke, so that the oxygen self-rescuer is suitable for various toxic and harmful gas and oxygen deficiency environments to rapidly evacuate accident sites.

The existing oxygen self-rescuer has an unreasonable structure, the breathing mode of the existing oxygen self-rescuer mostly adopts a mouth tool-nose clip type, when the oxygen self-rescuer is used for escaping, an upper cover needs to be opened and thrown away, then the mouth tool is bitten by mouth, and then the nose is clipped by the nose clip. The above-described method has the following drawbacks: firstly, the upper cover is discarded conveniently, so that garbage is produced, and the subsequent special cleaning is needed, which is very troublesome; secondly, the nose clip clamps the nose, and the travelling comfort is relatively poor to, the nose clip is easy to be slipped off, and the safety protection effect is relatively poor.

SUMMERY OF THE UTILITY MODEL

According to the not enough among the above prior art, the utility model discloses the technical problem who solves is: provides an oronasal mask type self-rescuer which is comfortable and convenient to wear and has better safety protection effect.

Oronasal mask type self-rescuer, including lower casing, upper cover and gasbag, the port department of gasbag is fixed with the breathing gas and connects, is equipped with induction port and exhaling mouth, its characterized in that on the breathing gas connects: the inner side of the upper cover is provided with an oronasal mask, a breathing air joint is fixedly connected with the oronasal mask, and an air suction port and an exhalation port on the breathing air joint are communicated with the inner cavity of the oronasal mask.

The longitudinal section of the upper cover in the left-right direction is triangular.

The port of the mouth-nose mask is fixed with a soft mask.

The upper cover is fixed with a bandage corresponding to the mouth-nose mask.

The front side of the lower shell is provided with an absorbent observation window which corresponds to the purification tank in the device, so that the color change of the carbon dioxide absorbent in the purification tank can be observed, and whether the carbon dioxide absorbent loses efficacy or not can be judged.

The foretell front side of casing down is equipped with two corresponding slots, and it has the data plate to peg graft in two slots, carries out fixed connection through a screw between data plate and the casing down, and traditionally, the data plate needs four screws to fix four angles respectively under on the casing, and is very troublesome, through setting up the slot, only needs a screw can fix the data plate, and is very convenient.

Compared with the prior art, the utility model beneficial effect who has is:

oronasal mask type self-rescuer, its upper cover is from taking the oronasal mask, has replaced original oral utensils-nose clip structure, wears more comfortable, convenient to, avoided the emergence of nose clip landing phenomenon, the safety protection effect is better.
