Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is applied to an oxygen inhaler and is intended to extract oxygen directly from a small oxygen cylinder and inhale it, and to prevent the cylinder from being accidentally opened when not in use. be.

People with respiratory diseases such as aX or asthma may have sudden attacks, and when they occur, it is often very painful, but if a small amount of oxygen can be supplied, the attack can be made milder. However, it is difficult to predict seizures, and we do not know when or where they will occur, so a portable, small, and easy-to-use oxygen inhaler is essential.

Such an inhaler can be used not only for patients, but also as a simple respirator in the event of an emergency evacuation such as a fire by installing a mask at the gas outlet.

Therefore, the present invention employs a small oxygen cylinder. When the neck of this cylinder is screwed into the mounting hole of the oxygen extractor, the sealing plate is cut by the puncture needle protruding from the hole, and oxygen is ejected. Oxygen is continuously supplied. Because such inhalation or respiratory equipment is used in emergencies due to its nature, 1.
It is desirable that the sealing plate of the cylinder screwed into the extractor be in close contact with the puncture needle, but since the positioning is uncertain, the sealing plate may be opened by screwing in the cylinder by mistake during inconvenient times, or vibrations etc. There is a problem with the cylinder becoming loose.

The X invention fits a removable collar, -, into the neck of the cylinder,
These problems were solved by tightening the cylinder to the sloper.

This color is partially equipped with a KM explanatory section. This l1w
Make a cut in the P back part with dimensions smaller than the outer diameter of the cylinder neck,
It is preferable that the collar is in the shape of a broken ring, but it is also possible to make the collar into a ring shape and have a part that is made thinner or perforated to make it easier to remove the carapace. If it is made of elastic material, it can be used repeatedly, but any material other than elastic material may be used as long as it can be easily deformed or cut by tensile force and removed from the neck.

Therefore, the thickness of the collar in the axial direction is designed depending on the material so that the puncture needle and sealing plate can swim close together when the neck of the cylinder is tightly screwed into the extractor.

The collar also has a handle for pulling out and diametrically opposed to the detachment part. This handle part may be a simple finger rest, or the handle part may be formed into a ring part and bent in the middle so that it can be hooked on a nail etc. 9. Bend it and apply adhesive to the handle or use it on pillars, etc.! ＃You may be asked to put your inhaler on. In this case, the inhaler will be placed in a designated place, and you will be provided with a place to put it when you are at home or at work after carrying it. It is also convenient to keep a spare.

Embodiments of the invention will be described in detail below with reference to the drawings.

1 is a small oxygen cylinder with a screw 8 cut on the outer periphery of the neck 2, an opening at the end of the neck 2 is sealed with a sealing plate 4, and oxygen is press-fitted into the neck 21 with an m5Fi collar. It has a through hole 6 through which it passes, and is partially equipped with a KIIIm removal scheduled portion 7. Reference numeral 8 denotes a mounting hole 9 for screwing the neck 2 of the cylinder 1 in the oxygen extractor, a hollow puncture needle 101 provided in this hole, and a passage 11 from this needle. It is connected to the adjustable back pressure means 12 and enters this passage 11, depending on the internal pressure! ! It is equipped with a bottle 16 that controls the flow path cross section between 1B and its own slope 14, a throttle 4P16 that adjusts the flow rate fI-g4 of outflow oxygen, and a 111-piece outlet port 17 whose flow rate is adjusted by a valve. . The cylinder L is fitted with the collar 5 on its neck 2, and the southern part of the neck is screwed into the mounting hole 9, and the collar B is attached to the 1111 of the sloper 8.
11 surface and the edge of the through hole 6 of at is pressed against the bong 61 and tightly integrated. The thickness T of the collar 5 in the axial direction is such that the outer surface of the sealing plate 4 and the tip of the puncture needle 10 are close to each other in this integrated state, that is, in relation to the pitch or number of threads of the screw, the cylinder 1 is It is designed to maintain a state in which the sealing plate 4 can be brought into contact with the puncture needle 10 by rotating a relatively small rectangular electric ceramic.

In the drawings, this is a handle portion that is diametrically opposed to the scheduled detachment portion 7 of the 211i collar 5 and bent outward.

8 to 5 each show different embodiments of the color. Fig. 8 shows a ring-shaped one, Fig. 4 shows a handle 21 with a through hole 22 for hanging a bow on a nail, etc., and Fig. tA5 shows a handle s21 coated with a sealant zat-, which is then used as a base. It is designed to be welded to the pillar, and in the case of both Figures 4 and 5, if it is bent at the point [11 minutes], the poet's instrument can be supported parallel to the pillar or Fi wall.

When using this inhaler, first the collar 5 is removed from the IT part 2, and then the cylinder I is further screwed into the extractor 8.

Then, the sealing plate 4 is cut by the puncture needle 10, and oxygen is ejected into the passage 11. The flow then flows to the throttle valve 16 while being balanced with the back pressure means 1z, where the flow rate is adjusted and the flow is adjusted to the outlet port 1.
7 and is used for inhalation. It can be used repeatedly by changing the cylinder.

According to the present invention, by attaching a small cylinder containing oxygen under pressure to the extractor, it is possible to cut the oxygen and adjust the flow rate for inhalation. Since the close position is maintained and restrained, there is no chance of accidentally cutting the sealing plate, and the cylinder will not fall off from the extractor due to shaking.If the collar is removed, the sealing sheet metal can be cut with a slight rotation of the cylinder. It has various features such as being able to be used quickly in an emergency, and being able to be used repeatedly by replacing the cylinder.
