Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This device is intended to prevent the occurrence of personal injury due to inhalation of toxic gases such as carbon monoxide, hydrogen cyanide, hydrogen chloride, acrolein, formaldehyde, etc. generated by combustion in the event of a fire in an oxygen respirator for emergency evacuation, especially in buildings. , Oxygen respirators used to secure exhaled oxygen during evacuation behavior.

[0002]

[Prior art and problems]

 Conventionally, as an oxygen respirator for applications such as sports and mountain climbing, a small pressure cylinder is filled with compressed oxygen, and a breathing mask member is attached to the on-off valve-equipped jet port of the cylinder. It is known that by operating the open / close valve with a fingertip while pressing it against the mouth of the face, oxygen can be breathed for several minutes with the oxygen ejected from the cylinder.

On the other hand, in the event of a building fire, the number of personal injury accidents due to the above-mentioned toxic gases generated from organic combustible materials such as building materials and furniture has been increasing more and more recently, and for safe evacuation of victims, There is an urgent need to provide a means to supply safe air or oxygen during the evacuation action.

However, no oxygen breather suitable for such an emergency evacuation has been provided to the market yet, and in some hotels and the like, the oxygen breather for sports and leisure as described above is evacuated to the guest room. It is considered to be stocked as a tool.

However, the oxygen respirator as described above holds a cylinder with one hand and sucks oxygen while pressing a mask part attached to the upper end of the cylinder against the mouth, which limits the freedom of body movement. Therefore, it was not suitable for emergency evacuation.

[0006] In view of the above background, the present invention aims to provide an oxygen respirator that can be suitably used for emergency evacuation in the event of a building fire.

[0007]

[Means for Solving the Problems]

 For the above-mentioned purpose, the present invention has an oxygen cylinder filled with compressed oxygen or liquid oxygen, an oxygen suction mask equipped with a fitting that can be worn by covering at least the mouth of the face, and an oxygen ejection port and suction port of the cylinder. An emergency characterized by comprising a combination with a flexible air supply hose that communicates with a mask, and the oxygen cylinder is provided with a fitting tool that allows the cylinder to be removably mounted on the body. The main point is the oxygen respirator for evacuation.

[0008]

[Action]

 At the time of use, an oxygen cylinder is attached to the body, for example, on the lumbar region by the attachment device attached thereto, and the suction mask is also attached to the face with the attachment device. Then, during the evasive behavior, when the body becomes aware of the lack of oxygen, the on / off valve of the cylinder is operated with one hand to inhale the required amount of oxygen. The victim will evacuate to a safe place for the required time while repeating such oxygen breathing intermittently.

[0009]

【Example】

 In the illustrated embodiment, an oxygen evacuation device (1) for emergency evacuation according to the present invention is mounted by covering a small oxygen cylinder (2) in which compressed oxygen or liquid oxygen is enclosed and a mouth and nose of the face. It consists of a possible suction mask (3) and a flexible synthetic resin air supply hose (4) that connects them together.

The oxygen cylinder (2) comprises a known so-called spray can having an opening / closing valve at the upper end and an operation button (6) with a gas ejection port (5) on the opening / closing valve. Oxygen having a purity of about 80 to 95% is pressure-filled in an amount capable of supplying breathing oxygen for about 5 minutes. The cylinder (2) is provided with an annular fitting (8) equipped with a hooking member (7) at the upper end of the body circumference, and the hooking member is attached to the edge of a garment or a belt. It is said that it can be worn on the body by hooking it on (9).

On the other hand, the suction mask (3) has a wearing tool (10) which is also made of a stretchable cord or the like, and by hanging it on the back of the head, the mask can be held in a face wearing state. There is.

The air supply hose (4) has one end connected to the gas ejection port (5) on the cylinder (2) side and the other end connected to the air supply port (11) of the suction mask (3). is there.

As shown in FIG. 1, the evacuation oxygen respirator (1) described above comprises an oxygen cylinder (2) equipped with a fitting (8), an air supply hose (4) and a suction mask (3). The three members will be prepared as a set by combining them, and the required number will always be available in the office of the building, guest room of the hotel, etc.

Then, in the event of a fire, the victim (M) attaches the oxygen cylinder (2) and the suction mask (3) to their body as shown in FIG. 2 with their respective attachment tools (8) and (10). To do. Since the victim (M) can move his / her limbs freely in this wearing state, he / she can quickly operate the evacuation behavior and operate the oxygen cylinder (2) with one hand each time he becomes aware of the oxygen deficient state during the behavior. Press the push button (6) to suck the required amount of oxygen. By repeating such an operation, it is necessary to evacuate to a safe place.

It should be noted that the illustrated embodiment merely shows one configuration example of the present invention. This idea is not limited to the specific configuration of the embodiment, and any design change is allowed within the scope described in the scope of the utility model registration claim.

[0016]

[Effect of device]

 As described above, the present invention is composed of a combination of an oxygen cylinder, a suction mask, and an air supply hose connecting these, and since it can be appropriately attached to the body by a wearing tool and used, It can be suitably used as an oxygen respirator for emergency evacuation without being restricted in movement and for preventing damage caused by toxic combustion gas in a building fire, which has recently become a problem. In addition, the structure is simple, and because it can be manufactured and provided at low cost, it is economically economical to use as a regular equipment, suitable for widespread use, and eventually human disaster in preparation for building fire. Can contribute to preventive measures.
