Description

[Detailed explanation of the invention] This invention is a simple mouthpiece that can be used to bite the mouth when evacuating through smoke due to a fire, prevent breathing through the nose, filter smoke, and breathe through the mouth. Regarding respiratory evacuation equipment.

When evacuating in such smoke, the most complete respiratory protection from the smoke is in the form of a gas mask, but this is very expensive and can be used in hospitals, hotels, etc. for all occupants. It is difficult to always have one on hand to wear in the event of a fire.

Therefore, in such cases, wet a towel and cover your nose and mouth.
Although people are advised to evacuate, they cannot be expected to search for towels or faucets in a timely emergency, and may even end up delaying their escape.

Therefore, the present invention is small and can be carried around or stored in the drawer of a desk near you. They placed it on their noses to prevent them from breathing through their noses, filtering the smoke, and allowing them to breathe through their mouths while evacuating.

In order to reduce the overall size of the nosepiece, it is always kept face down, but when it is face down, it is preferable that the free end side of the mouthpiece is covered to protect it hygienically.

The present invention will now be described with reference to the illustrated embodiments.

In Figures 1 to 4, 1 is a hollow body in the shape of a flat case, and in this case, the body is a S゛ square with a side of about 10 cm, and as shown in Figure 4, the front side faces the face when in use. A slope 1' is formed between the upper surfaces, and a mouthpiece 2 for biting into the mouth protrudes from the slope.

In addition, in this embodiment, a hole 3 is provided inside the corner formed by the top surface and the rear surface.
' A storage chamber 5 for a bag 4 containing water on the top thereof,
A filtration chamber 7 is formed below, into which a filtration material 6 such as Japanese paper, cloth, or cotton is placed.

This filtration chamber 7 forms part of a supply/discharge passage 9 that meanders in the vertical direction from a breathing intake/discharge port 8 on the rear surface of the main body to the mouthpiece 2. This is a baffle wall to be formed in a meandering manner.

The main body 1 includes a box 1a having a bottom, a spout 2, walls 3 and 9', and a lid plate 1b that closes the open surface of the box 1a, which are made of, for example, a suitable synthetic resin, and the lid plate is glued to the open surface of the box. It can be formed by fixing.

Note that if molding a wall having holes such as the split wall 3 integrally with the box 1a would complicate the mold, it may be molded separately and fixed by adhesive or the like.

A shaft 10 is pivotally attached to the storage chamber 5 in which a bag containing water is placed by penetrating the small diameter portions at both ends through holes in the bottom of the box and the lid plate, and a shaft 10 is attached to both ends of the shaft 10 protruding outward from the main body. fixes the nose pad 11 and allows the nose pad 11 to rise and fall on the upper surface of the main body.

The nose pad has an L-shaped waist so that it can cover the top surface of the main body and the upper half of the front surface. When placed face down on the top surface of the main body, the top surface and
The upper half of the front is covered to shield the mouthpiece 2 from the outside.

Preferably, the side edges of the nose pad are provided with side walls 11' that slide into contact with the bottom of the main body and the outer surface of the lid plate, so that the cross-sectional shape is in the form of a concave groove, and the friction prevents the nose pad from accidentally rising from a prone position. It is good to prevent this.

Further, the nose pad 10 may be made to lie slightly on the upper surface of the main body by a spring force, and for this purpose, for example, a coil spring may be wound around the shaft 10, and one end of the coil spring may be attached to the nose pad and the other end to the main body.

A blade 13 is attached to a shaft 10 that rotates in the storage chamber as the nose pad rises and falls.When the nose pad is face down, the blade 13 is retracted from the bag 4, but when the nose pad is raised, the blade 13 is removed. The tip moves towards the bag, cuts the bag and drains the water inside into the storage chamber 4.
Put it inside.

Therefore, when not in use, the nose pad is placed face down on the top of the main unit, so as mentioned above, the main unit is relatively small, and can be carried around at all times by putting it in a clothing pocket or band bag. It can also be kept in a drawer in the guest room.

When a fire breaks out and you are evacuating, raise the nose pad 11, pinch the bridge of your nose from both sides with the cut grooves 12 at its free end, and put the mouthpiece in your mouth (Figure 4) to breathe through your mouth.

In this embodiment, the blade 1 is rotated by the rotation of the shaft 10 when raising the nose pad.
3 cuts the bag 4, so the water comes out into the storage chamber 4 and enters the hole 3' in the side wall.
In order to moisten the filter material 6 in the chamber, the air in the intake air is taken into the meandering passage 9 of the main body from the intake/exhaust port 8 and sucked through the mouthpiece 2 along with the smoke when breathing through the mouth. Smoke components are separated and removed by a filter medium 6 in a filter chamber 7.

Therefore, it is possible to prevent accidents such as inhalation of smoke, damage to the respiratory tract, inability to evacuate, and death by burning.

Furthermore, since the mouth cuff is held in place by the bite, both hands can be used freely, allowing you to use both hands to search for a safe place, hold on to a rope or other object with both hands to evacuate, and use one hand to cover your mouth and nose with a towel. This allows for faster and safer actions compared to having only one free hand.

If necessary, smoke can be separated and removed by providing a packed layer 14 of activated carbon particles as shown in the figure or a filter chip 15 such as that used in the mouthpiece of a cigarette or a pipe in the meandering passage or in the cylinder. It can also be effective.

Note that 16 indicates a string hole for hanging the device on a wall or the like.

In addition, in this embodiment, a bag 4 containing water in a sealed body,
Although it is expected that the filter material 6 will be stored and used in a disposable manner, the lid plate 1b is made removable from the box 1a of the main body.
After use, the lid plate 1b can be opened, the inside cleaned, and a new bag 4 or filter material 6 inserted again, so that it can be used repeatedly.

Even if the device is not used for a long period of time, the nose pad 11 lies down on the upper surface of the main body to protect the mouth tube 2 from bruises, so the tube portion does not get dirty and is hygienic.

Although the main body is square in this case, it is not limited to this, and can be circular or any other shape.

The nose pad 11 of the above-described embodiment had a cut groove 12 at the free end to sandwich the bridge of the nose.

Therefore, if the device is placed face down and lightly biased by a spring, when the device is placed in the mouth, the spring force will press the bridge of the nose, making it difficult to breathe through the nose.

However, in addition to pressing the bridge of the nose with the cut groove, the nosepiece has two protrusions 17 on the outer surface of the tip bent into an L shape, for example, as in the embodiment shown in Figs. 5 and 6, which enter the nostrils. It can be anything.

When using it, raise the nose pad a little while it is lying down, and press the protrusion 17.
Put it in your nostril and bite the mouth tube 2.

Therefore, in this case, the nose pad may be biased in the opposite direction by a spring wound around the shaft 10, and the spring force may be used to lightly press the tip of the nose pad with the protrusion toward the bottom of the nose. preferable.

When not in use, the side wall 11' of the nose pad and the side wall of the main body have a protrusion 18 on one side and a recess 18' on the other side.
The protrusion 18 is inserted into the recess 18' to lightly prevent the nose pad from rising.

As is clear from the above, according to the present invention, it is possible to provide a simple evacuation device that makes it difficult to breathe through the nose with the nose pad, while allowing the person to breathe through the mouth by holding the person's mouth in place and evacuate using both hands.

In this case, paper, cloth, cotton, etc. were used as the filter material to be moistened, but when using a filter material that performs chemical filtration without being moistened, the water storage chamber 4, the shaft The attached blade 13 may be omitted.
