In the end, the pressure screw 415 compresses the pressure spring 416 and supports the pressure thin film 413, and the pressure thin film 413 does not rise more than a certain distance due to the step formed at the bottom of the pressure control pipe 411, and also Due to the fixing of the rim by the pressure thick film 412, it may be configured to be pushed out by the pressure spring 416 only by a predetermined distance.

At this time, when the pressure screw 415 is rotated in one direction, the pressure screw 415 moves inward along the pressure coupling pipe 414, and the pressure spring 416 moves the pressure thin film 413 in the direction of one surface of the pressure space part 400. The pressure thin film 413 blocks the air hole formed at the bottom of the pressure control pipe 411, and the pressure thick film 412 is connected to the pressure thin film 413 to block the inflow of external air. By covering the outlet of the pressure coupling pipe 414, 415 can seal the pressure space part 400.

Accordingly, the pressure space part 400 and the joint body 100 connected thereto are formed in a high-pressure state, so that oxygen supplied to the user can be strongly injected at a high pressure.

On the other hand, when the pressure screw 415 is rotated in the other direction, the pressure spring 416 is relaxed as the pressure screw 415 moves outward along the pressure coupling pipe 414 and the force applied to the pressure thin film 413 is weak. As the pressure thin film 413 moves in the direction of the other surface of the pressure space part 400, the air hole of the pressure control pipe 411 can be ventilated.

Therefore, the air in the pressure space unit 400 is vented through the joint body 100 and the breathing control unit 420, the sealed state is released, and the pressure may be lowered.

Due to the characteristics of the pressure control unit 410 described above, the disposable mechanical oxygen respirator 10 of the present invention needs to be strongly supplied with high-pressure oxygen depending on the user's condition and medical environment, or, conversely, the low-pressure oxygen should be weakly supplied. In such a case, it may be an advantage of providing oxygen of an appropriate pressure through the adjustment of the pressure control unit 410.

The breathing control unit 420 may function to control the amount of oxygen flowing out of the joint body 100 through the breathing control unit 420, and thereby the amount of oxygen supplied into the joint body 100 may be adjusted.

Therefore, when the amount of oxygen discharged from the breathing control unit 420 increases, the amount of oxygen supplied from the joint body 100 to the mask connection unit 300 decreases, so that the user breathes faster to inhale the appropriate amount, and, conversely, the amount of oxygen flowed out decreases. Then, the amount of oxygen supplied by the user increases, so that the user can breathe slowly.

The breathing control unit 420 may function to control the user's breathing cycle through the control process.

To this end, the breathing control unit 420 may be configured to include a breathing control tube 421, a breathing coupling tube 422, and a breathing screw 423.

The breathing control pipe 421 is a truncated cone shape protruding from the inside of the pressure space part 400 and has an open shape at both ends, and the upper end is the bottom of the pressure space part 400, that is, the upper part of the pressure space part 400 from the other surface, That is, the diameter may be narrowed in a direction toward one side and formed.

The breathing control pipe 421 may be provided side by side with a predetermined distance apart from the pressure control pipe 411 inside the pressure space part 400, but the pressure control pipe 411 It has a shape that penetrates the floor, but the breathing control tube 421 may be configured in a shape that is spaced apart from the upper part and in contact with the floor.

The breathing coupling tube 422 has one end connected to the breathing control tube 421 and the other end is a pipe shape protruding outward of the pressure space part 400 and may be configured by forming a spiral around the inner periphery.

The breathing coupling pipe 422 has a shape similar to the pressure coupling pipe 414 and may be configured to be disposed in parallel with the pressure coupling pipe 414 on the outside of the other surface of the pressure space part 400.

The breathing screw 423 may be inserted into the breathing coupling pipe 422 and configured in a shape such as a stopper that rotates along the breathing coupling pipe 422.

One end of the breathing screw 423 is composed of a rotating handle, and the other end is composed of a truncated cone that is accommodated in the breathing control tube 421, and the other end is inserted and mounted in the breathing coupling tube 422, and the breathing control tube is rotated. Can be accommodated in (421).

The breathing screw 423 may be rotated by being inserted into the breathing coupling pipe 422 by forming a spiral around the outer periphery of the connecting portion at the center and the other end.

The breathing screw 423 may be provided with at least one or more through holes at the other end side, and at least one or more through holes may also be provided at the outer periphery of the central portion and the handle connecting portion.

That is, the breathing screw 423 may be provided with a plurality of through holes through which air can pass through one edge and the other edge, and may rotate along the breathing coupling pipe 422 due to the spiral formed in the side edge of the central portion.

Since the top of one end of the breathing screw 423 is formed in a structure that is closed without a through hole, when the breathing screw 423 is completely tightly accommodated in the breathing control tube 421, it blocks the open part of the upper end of the breathing control tube 421, so the pressure space part The 400 and the pressure coupling pipe 414 may have a structure in which ventilation is blocked.

With the above structure, when holding the handle of the breathing screw 423 and rotating it in one direction, the breathing screw 423 moves upward in the direction of the breathing control tube 421 along the breathing coupling tube 422.

As the breathing screw 423 is accommodated and fitted in the breathing control tube, the area ventilated to the outside of the breathing coupling tube 422 through the upper end of the breathing control tube 421 inside the pressure space part 400 decreases gradually.

Therefore, since the rate at which oxygen is discharged through the breathing coupling pipe 422 in the inner space of the pressure space unit 400 is slowed, the user is provided with a sufficient amount of oxygen so that the user can breathe slowly.

On the other hand, when holding the handle of the breathing screw 423 and rotating it in the other direction, the breathing screw 423 moves downward along the breathing coupling tube 422 in the outward direction, and at the same time, the breathing screw 423 is spaced apart from the breathing control tube. The area ventilated to the outside of the breathing coupling tube 422 through the upper end of the breathing control tube 421 from the inside of the pressure space part 400 is gradually increased.

Therefore, the rate at which oxygen is discharged through the breathing coupling pipe 422 in the inner space of the pressure space unit 400 is increased, so that the user must rapidly breathe in order to drink a sufficient amount of oxygen.

By rotating the breathing screw 423 by the same principle as described above, it is possible to adjust the frequency of breathing at which the user should rest by moving closer to or away from the breathing control tube 421.

Therefore, the disposable mechanical oxygen respirator 10 of the present invention is suitable for breathing through the control of the breathing control unit 420 in the case of having to breathe quickly and quickly depending on the condition of the user and the medical environment, or in the case of having to breathe slowly. It can be a number of features and advantages that can be provided.

Finally, the oxygen supplement 600 may supply air into the joint body 100 through the oxygen supplement 600 from the outside of the respiratory tract when oxygen inhaled in the joint body 100 is insufficient, and conversely, the joint body ( 100) It is possible to function to maintain an appropriate amount of oxygen in the joint body 100 by blocking the leakage of oxygen from the inside to the outside.

To this end, the oxygen supplement part 600 may include an oxygen cap 610 and a blocking film 620.

The oxygen cap 610 may be configured in a shape in which a protrusion is provided at the center of one surface and a plurality of radial supports for maintaining the shape by connecting the protrusion to the inner circumferential surface as a pipe shape having one surface partially closed and the other surface open.

As a result, one surface of the oxygen cap 610 may be provided with a protrusion in the center and a plurality of radial through holes around the protrusion may be provided.

The blocking film 620 is a flexible thin film having a shape corresponding to one surface of the oxygen cap 610 and has a through hole in the center thereof, and may be fitted and coupled to the protrusion of the oxygen cap 610.

The blocking film 620 is inserted into the protrusion on one side of the oxygen cap 610 and is formed of a soft material such as rubber, and may be made of a light material that can be bent or folded even by a small amount of wind. It may be composed of a material that does not pass through.

Since the blocking film 620 is in close contact with the protrusion of the oxygen cap 610, it may be provided so as not to be separated from the oxygen cap 610.

The oxygen supplement part 600 may be mounted so that one surface of the oxygen cap 610 provided with the blocking film 620 is in contact with the inside of the joint body 100 and the other surface of the opened oxygen cap 610 is directed to the outside.

When air is injected from the outside of the oxygen replenishing unit 600, that is, from the outside of the joint body 100 to the inside, the blocking film 620 is bent inside the joint body 100 and allows air to be introduced.

Conversely, inside the joint body 100, even if the air moves in the direction of the oxygen replenishing unit 600, the blocking film 620 is blocked by the radial support provided on one side of the oxygen cap 610 and cannot be bent, so the inside of the joint body 100 The outflow of oxygen can be blocked.

Therefore, when the oxygen supplement part 600 is insufficient air sucked into the disposable mechanical oxygen respirator 10 of the present invention, external air is pushed in due to a pressure difference with the outside. By allowing air to enter, it can function as an air inlet passage.

On the other hand, since the blocking film 620 cannot bend from the inside of the joint body 100 to the outside, the air inside the respirator can be prevented from flowing out of the respirator.

Accordingly, the user is able to maintain breathing by receiving the necessary oxygen through the oxygen supplementing unit 600 in addition to the oxygen supply unit 200.

Based on the above description, an example of use of the disposable mechanical oxygen respirator 10 according to a preferred embodiment of the present invention will be described.

First, it is checked whether the safety valve 500 and the oxygen supplement 600 are correctly and firmly mounted.

The safety valve 500 is opened to check whether the spring is engaged and whether the spring is engaged, and the oxygen supplement part 600 is opened to check the state of the blocking film 620 and the bonded state.

Thereafter, the pressure screw 415 and the breathing screw 423 are rotated to check whether they move normally, and the state of the pressure control unit 410 and the breathing control unit 420 is checked, and then the pressure screw 415 and the breathing screw 423 Are placed at predetermined positions in the pressure coupling pipe 414 and the breathing coupling pipe 422, respectively.

In addition, the oxygen tube of the external oxygen supply device is connected to the main supply pipe 210 of the oxygen supply unit 200 and the amount of oxygen to be supplied to the user from the oxygen supply device is set.

In order to set the oxygen supply amount up to one day, the lid of the sub-supply pipe 220 is opened, another oxygen tube is connected, and the total amount is set by mixing with the supply amount of the main supply pipe 210, but it can be set in detail up to one day.

An oxygen mask to be worn by a user is connected to the mask connection part 300.

An oxygen mask may be directly mounted on the front end of the mask connection part 300, or a mask tube connected to the oxygen mask may be connected to form an oxygen supply passage.

Now, by operating an external oxygen supply device, oxygen is supplied to the disposable mechanical oxygen respirator 10 of the present invention through the oxygen supply unit 200.

The air introduced into the joint body 100 is supplied to the user's oxygen mask through the mask connection unit 300, and at this time, the pressure of the supplied oxygen is displayed on the barometer 310.

When it is determined that the pressure of oxygen displayed on the barometer 310 is less than the appropriate level suitable for the user, the user or the auxiliary personnel rotates the handle of the pressure screw 415 in one direction to connect the pressure screw 415 to the pressure coupling pipe 414 Move upwards to the inside.

As a result, the internal pressure of the pressure space unit 400 increases, and oxygen supplied to the user may be introduced at a higher pressure.

On the contrary, if it is determined that the pressure of oxygen displayed on the barometer 310 is excessive than the appropriate level, the pressure screw 415 is moved down to the outside of the pressure coupling pipe 414 and the pressure inside the pressure space unit 400 can be reduced. Oxygen provided to the patient can be introduced at a lower pressure.

While rotating the pressure screw 415 in the pressure control unit 410, the pressure screw 415 is raised so that the change in the scale of the barometer 310 is checked at the same time, and the oxygen pressure of the desired value is displayed on the barometer 310. By repeating the lowering procedure, the pressure control unit 410 may be adjusted to provide an appropriate level of oxygen pressure in accordance with the pressure required by the user.

However, if excessive pressure is set due to a mistake in operation or careless use, high-pressure oxygen is strongly injected to the user, resulting in a dangerous situation.At this time, excessive oxygen pressure in the respirator pushes the safety plate 520 of the safety valve 500. The safety valve 500 operates so that an appropriate pressure in the respirator can be formed while discharging excess oxygen inside the respirator along the perforation of the rim of the safety cap 510, thereby preventing a dangerous situation that may occur to the user. have.

When the exhaustion of excess oxygen is completed, the safety spring 530 pushes the safety plate 520 back to the inside of the front end of the joint body 100, and the safety valve 500 is restored to a state that blocks the flow of air between the inside and the outside again. Can be.

If adequate oxygen is not supplied in the respiratory tract due to a problem with the oxygen supply unit 200 or the oxygen supply unit, air is introduced from the outside of the oxygen supply unit 600 to push the barrier 620 and enter the respiratory tract. It can supplement the supply.

On the other hand, the air inside the respiratory tract is blocked by the blocking membrane 620 so that it does not leak out and does not cause oxygen shortage in the respiratory tract.

On the other hand, when the adjustment of the pressure control unit 410 is completed, the breathing control unit 420 is then adjusted according to the user's respiration rate.

If the user needs to slow the breathing, the breathing screw 423 is rotated in one direction and moved upward in the breathing coupling tube 422 so that the oxygen in the respiratory tract is brought into close contact with the inside of the breathing control tube 421. ) Reduce the rate of outflow to the outside so that the user can receive a sufficient amount of oxygen even if he breathes slowly.

On the other hand, if the user needs to breathe quickly, the breathing screw 423 is rotated in the other direction so that it is moved to the lower part of the breathing coupling pipe 422, that is, the pressure space part 400 outward. By increasing the gross area of the through-hole, it is possible to increase the rate at which oxygen is discharged to the outside through the pressure screw 415 through the pressure control pipe 411 in the pressure space part 400.

In this way, the user can be induced to breathe quickly in order to inhale a sufficient amount of oxygen.

The embodiments of the present invention described above are merely exemplary, and those of ordinary skill in the art to which the present invention belongs will appreciate that various modifications and other equivalent embodiments are possible.

Therefore, it will be appreciated that the present invention is not limited to the form mentioned in the detailed description above. Therefore, the true technical protection scope of the present invention should be determined by the technical spirit of the appended claims.
