Artificial respiration device

This invention relates to artificial respiration devices and, more particularly, to an artificial respiration device that provides oxygen to a patient who is unable to breathe on their own.

Generally speaking, the artificial respiration device is suitable for a hospital patient's heavy patient room or emergency room, and the patient is made to supply oxygen to a patient who has just stopped breathing or a patient who is unable to breathe on his own, or a purpura patient who can breathe spontaneously but has hypoxia. A device that can breathe automatically.

For such artificial respiration devices, it is important to supply oxygen in an amount of oxygen that matches the patient's ability to breathe, as well as in the breathing cycle associated with the prior art, including the automatic breathing disclosed in U.S. Patent No. 5,520,170. Device.

According to the automatic breathing apparatus disclosed in the prior patent, a menu button and a slider control item are provided on a casing having an oxygen inflow port and a discharge port, and a pressure regulator, a main switch, and a time back are provided inside the casing. The organic operation of the ring, on-demand air supply valve, flow control rotor and diaphragm sleeve provides oxygen for the patient to breathe.

Further, the prior art automatic breathing apparatus adjusts the breathing cycle by forming a plurality of air holes on the disk to adjust the flow rate of oxygen and passing through the plurality of orifices. That is, the disk is rotated according to the slider control item, and the supply amount of oxygen and the supply period are changed by the change of the pore size and the volume of the orifice.

However, in the conventional automatic breathing apparatus as described above, the slider control item for rotating the disk is connected to the disk by another groove disposed on the side of the casing, so that the fabrication and assembly thereof become very complicated and constituent elements. Too much, leading to an increase in the unit price of manufacturing.

Further, in order to provide a functionally more convenient artificial respiration apparatus, the applicant of the present invention applied to the Korean Patent Office for a utility model and registered an automatic respirator for an oxygen supply No. 20-440379. In order to facilitate understanding of the scope of the claims (the reference numerals are included in the registration bulletin), the timing cylinder 200 is provided to be capable of transmitting the breath of the patient supplied to the adjustment valve 400. The regulator 100 supplies oxygen supplied to the main valve 300 to isolate the oxygen supplied from the regulator to the main valve; the main valve 300; the regulator 100, after the supplied oxygen becomes a prescribed pressure, supplies it to the stage. The main valve 300 and the timing cylinder 200; the regulating valve 400, when the oxygen of the main valve 300 is transmitted to the air supply unit 600 described below, the supply of oxygen supplied to the oral cavity of the patient is adjusted according to the operation of the handle 410; In unit 600, when the patient spontaneously breathes through the spontaneous breathing unit 500, the patient's breathing is reversely supplied to the adjustment valve 400.

Here, the main valve 300 includes a first oxygen inflow hole 310 connected to the regulator 100 and the adjustment valve 400, and is opened and closed according to the operation of the first piston 360 built in the inside; and the second operator inflow hole 350 is connected to the timing cylinder on a side of the first cover 370 that supports the first oxygen venting hole 330 and supports the first piston 360, respectively. The timing cylinder 200 includes a first operator inflow hole 230 and The first operator vent 250 is openable and closable by the second piston 270; and includes a third ventilator inflow hole 210 connected to the regulating valve on a side of the second cover 240 supporting the second piston 270; The valve automatically opens and closes according to the operation of the timing cylinder.

Further, the adjustment valve 400 is provided with an actuator 470 to adjust the supply amount of oxygen supplied from the main valve 300 to the air supply unit 600, and includes an adjustment pin 450 that can adjust the amount of oxygen supplied to the timing cylinder 200. Adjust the number of breaths according to the size of the patient.

Moreover, in the automatic respirator, the regulating valve 400, the spontaneous breathing unit 500, the air supply unit 600, and the fixed cap 670 are disposed in the vertical direction of the outer casing 700, and the regulator 100, the main valve 300, and the timing are arranged in the horizontal direction of the outer casing 700. Cylinder 200.

Further, the adjustment valve 400 has a tapered surface 470a formed at the end of the actuator 470 to accurately control the amount of oxygen.

At the same time, the air supply unit 600 includes a mask interface 660, an exhaust diaphragm 640, and an air supply valve 620, and one side of the air supply valve 620 further includes a drain valve connected to the main valve 300.

However, as in the prior art described above, as the decompressed oxygen is directly supplied from the regulator 100 to the timing cylinder 200, when the main valve 300 is closed, the oxygen of the regulator 100 is continuously supplied to the timing cylinder 200, according to which Since the operation of the main valve 300 is controlled by the timing cylinder 200 regardless of the operation state of the main valve 300, erroneous operation may result. That is, since the oxygen of the regulator 100 is directly supplied to the timing cylinder 200 that controls the operation of the main valve 300, the timing cylinder 200 may cause the main valve 300 to malfunction due to the oxygen of the regulator 100.

Also, when the handle 410 that has been connected to the actuator 470 having the tapered surface 470a is rotated, the actuator 470 is moved in conjunction with the amount of rotation of the handle 410, and can be relatively easily adjusted to be supplied to the timing by the actuator 470. When the amount of oxygen of the cylinder 200 is not precisely rotated by the handle 410 that is manually operated, it is actually not easy to precisely move the actuator 470, and the adjustment pin 450 for adjusting the amount of oxygen supplied to the human body for breathing. It is supported by the spring, but the adjustment pin 450 cannot be directly moved, and in fact, the amount of oxygen supplied to the human body cannot be precisely adjusted.

Further, the timing cylinder 200 and the spontaneous breathing unit 500 separately provided to control the operation of the main valve 300 together with the timing cylinder 200 are complicatedly constituted by the pressure plate 560, the sensor plate 550, the first and second respirator inlet and outlet holes 510, 530, and the like. , thus increasing the number of parts and greatly increasing the unit price of the product.

Further, the elastic force of the spring for supporting the exhaust diaphragm 640 provided in the air supply unit 600 cannot be adjusted, and when a defect occurs due to manufacturing dispersion or assembly dispersion, the amount of exhaust gas cannot be smoothly adjusted.

Not only that, although the emergency button 22 in the form of a manually operated trigger is provided, the configuration of the emergency button 22 is very complicated, which may cause erroneous operation, and the operational structure is complicated and the reliability of operation is insufficient.

The background art described above is intended to facilitate an understanding of the background of the invention, and may include other than the prior art known to those of ordinary skill in the art to which the invention pertains.

(Effects of the Invention) According to the present invention, even if the spontaneous breathing unit having a complicated configuration as in the prior art is not provided, the operation of the air supply control valve can be controlled, the manufacturing unit price can be reduced by reducing the components, and the manufacturing process can be shortened. The rotation of the knob of the flow regulating valve member connected to the flow control valve through the connector, the flow regulating valve member for controlling the flow of oxygen directly supplied to the human body is also rotated together to adjust the flow rate, and thus can be easily supplied to the human body The oxygen flow rate is adjusted to suit the human body.

In particular, by determining the rotation angle of the flow rate adjusting valve member based on the rotation angle of the knob, not only the responsiveness at the time of flow rate adjustment but also the amount of oxygen supplied to the human body can be precisely adjusted to a desired amount.

Moreover, as the knob is fixed to the flow regulating valve member through the connector, the knob can be detachably attached to the flow regulating valve member, so that the assembly convenience can be improved, and if necessary, the assembly can be reassembled, so that the knob can be reassembled and installed. Moreover, since the coupling member of the fastener constituting the connector is coupled to the isolation protrusion protruding from the rotation ring, the fixing of the knob to the flow regulating valve member by the rotation ring not only does not damage the flow regulating valve member, but also if necessary It is also possible to reassemble the rotating ring, and because the connector has a stopper, the rotation angle of the knob can be set to a desired angle, and the operation of the flow regulating valve member can be precisely controlled.

In addition, the spacer provided with the stopper can isolate the wing of the stopper from the flow regulating valve member to a desired distance, and can not only precisely control the operation of the flow regulating valve member, but also adjust The assembly of the rotating ring is spread.

Further, since the valve piston of the pressure reducing valve is operated in accordance with the pressure of the oxygen flowing into the pressure reducing cylinder of the pressure reducing valve, the pressure of the inflowing oxygen can be easily reduced, and even if there is no power source, the air supply control valve can be operated. The valve plunger is internally moved in accordance with the pressure of oxygen of the valve casing or the elastic force of the spring, thereby opening and closing the supply orifice or the discharge orifice, so that the supplied oxygen can be easily supplied or interrupted.

At the same time, since the oxygen supplied excessively through the supply air passage is discharged through the overflow unit, it is possible to prevent a safety accident due to excessive supply, and the pressure reducing valve of the overflow unit operates according to the oxygen pressure, so that the pressure reducing valve can be easily operated, and further, The valve disc of the pressure valve is supported by the disc support spring, which not only easily constitutes the pressure reducing valve, but also adjusts the elastic force of the disc support spring by the spring adjuster, so that the valve disc can be operated under the required pressure and precision The amount of exhaust gas is adjusted to the ground, and the spring adjuster is composed of a screw type structure, and the spring adjuster can be easily operated.

In particular, the operation control unit controls the operation of the air supply control valve in accordance with the pressure of the oxygen gas, in fact, the air supply control valve can be automatically operated, and the operation control valve of the operation control unit that controls the operation of the air supply control valve is bypassed. The operation of the air supply control valve can be controlled not only by gradually operating the operation control valve but also by operating part of the bypass oxygen during the partial operation of the valve.

In particular, the oxygen of the pressure reducing valve is not directly supplied to the operation control valve unlike the conventional one, and the operation control valve can be operated in accordance with the state of the air supply control valve, whereby the air supply control valve can be accurately and precisely adjusted.

Further, since the bypass valve is constituted by a tilt valve member having an oxygen filling chamber and an inclined surface, not only the bypass valve can be easily formed, but when the tilt valve member is configured to be pressurized by the flow rate adjusting valve member, simultaneous engagement can be performed. The flow rate of oxygen bypassed to the operation control valve is adjusted together with the flow rate of oxygen supplied to the human body, and the operation control valve is constituted by the valve chamber, the bobbin, and the bobbin spring, and is operated according to the oxygen pressure, so that the operation control valve can be easily operated automatically.

Further, since the manual control valve is provided, it is possible to manually supply oxygen to the human body in an emergency, and the manual control valve is mechanically operated, so that the manual control valve can be stably operated, and can be easily configured and equipped with a trigger. The manual control valve can be easily operated.

At the same time, the pressure of the oxygen supplied from the bypass valve to the operation control valve can be doubled by the pressurization chamber, so that the operation control valve can be smoothly operated.

Moreover, when the exhalation according to the spontaneous breathing is guided by the air supply path, the flow variable unit is interlocked with the air supply control valve or the manual control valve to discharge the oxygen to the outside or to isolate the exhaust gas, thereby depending on the exhaled human body. The exhaust air is not interfered (mixed) by oxygen, and it is possible to prevent the air from being re-inhaled due to the vortex of the exhaust air.

In particular, since the flow rate variable unit is constituted by a discharge valve connected to the supply air flow path and a switching valve that controls the operation of the discharge valve in conjunction with the air supply control valve or the manual control valve, the flow rate variable unit can be mechanically Running.

Further, the drain hole of the bleed valve is opened and closed by the opening and closing group that is operated by the oxygen supplied from the air supply control valve or the manual control valve, and can be operated correctly during exhalation.

Further, the needle of the switching valve is operated by the oxygen supplied from the air supply control valve or the manual control valve, thereby operating the opening and closing group of the discharge valve, so that the discharge valve and the air supply control valve or the manual control valve can be easily Generate linkage.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, for the convenience of description, the size and thickness of each configuration are arbitrarily illustrated in the drawings. Therefore, the present invention is not limited to the contents illustrated in the drawings, and the illustrations are expanded in order to clearly express the respective parts and regions. Its thickness. Further, in order to clarify the embodiment of the present invention, parts that are not related to the description are omitted. In the following description, the names of the configurations are divided into the first, second, etc., in order to distinguish the same names of the configurations, and are not limited to the order. . Moreover, in the entire specification, unless otherwise specified, a certain component including a component does not mean the exclusion of other components, but may also include other components. Further, terms such as a unit or a tool described in the specification mean a unit including at least one function or operation.

1 to 4, an artificial respiration apparatus according to an embodiment of the present invention includes a casing 10, a pressure reducing valve 20, an air supply control valve 30, a flow rate control valve 40, and an air supply path 60.

The outer casing 10 is used for connecting oxygen (oxygen) of an oxygen tank (not shown) to a respiratory organ of a patient, and includes: the pressure reducing valve 20, the air supply control valve 30, the flow control valve 40, and the air supply path 60, and The constituent elements to be described later are provided with a supply port 11 and a discharge port 12 on both sides.

Such a casing 10, a supply port 11 for supplying oxygen, is connected to an oxygen tank (not shown) through a connecting member such as a connector, and a discharge port 12 for discharging oxygen is connected to a member such as a breathing mask 13 to supply oxygen through the breathing mask 13. To the patient's mouth or nose.

Referring to Fig. 5, the pressure reducing valve 20 is built in the above-described outer casing 10, and supplies air to other constituent elements by reducing the oxygen pressure of the oxygen tank supplied from the supply port 11 of the outer casing 10. As shown, the pressure reducing valve 20 includes a pressure reducing cylinder 21, a valve piston 22, and a piston spring 23.

The decompression cylinder 21 is formed on one side of a gas supply tank 24 that receives compressed oxygen from an oxygen tank, and the gas supply tank 24 is provided with a valve seat 20a that forms a hole for venting oxygen, and the other side is formed to communicate with the gas supply tank 24, respectively. A plurality of exhaust tanks 25, 26 for discharging oxygen supplied from the gas supply tank 24 are discharged. At this time, the exhaust tanks 25 and 26 are configured such that the first exhaust tank 25 is connected to the air supply control valve 30 via the first flow path D1, and the second exhaust tank 26 is passed through the second flow path D2. It is connected to a manual control valve 70 which will be described later.

The valve piston 22 is movably built in by the oxygen pressure supplied to the inside of the decompression cylinder 21, and opens and closes a hole provided in the valve seat 20a of the air supply tank 24. As shown in the figure, the valve piston 22 opens and closes a hole of the valve seat 20a by a valve head 22a that is connected to the shaft. Such a valve piston 22 is normally supported by a piston spring 23 to be described later to open the valve seat 20a. That is, the valve piston 22 normally maintains the home position in accordance with the elastic force of the piston spring 23, and as shown, the valve head 22a is isolated from the valve seat 20a to open the valve seat 20a. Therefore, the valve piston 22 supplies the oxygen that has flowed into the air supply tank 24 to the first exhaust tank 25 and the second exhaust tank 26.

However, when the pressure of the oxygen supplied to the air supply tank 24 increases according to a pulse phenomenon or the like, the valve piston 22 moves in accordance with the increased pressure of oxygen, as illustrated in Fig. 6, shields the valve seat 20a. At this time, as shown in FIG. 6, the valve piston 22 compresses the piston spring 23 and moves together with the valve head 22a to shield the valve seat 20a. That is, the valve piston 22 closes the hole of the valve seat 20a by bringing the moving valve head 22a into close contact with the valve seat 20a. Therefore, the valve piston 22 interrupts the supply of oxygen supplied to the first exhaust tank 25 and the second exhaust tank 26.

Further, when the pressure of the oxygen supplied to the air supply tank 24 is again attenuated to the normal state, the valve piston 22 returns to the home position together with the valve head 22a as the piston spring 23 re-expands. At this time, the valve piston 22 reopens the valve seat 20a and the air supply tank 24 re-supplies oxygen to the first exhaust tank 25 and the second exhaust tank 26.

In general, the valve piston 22 repeatedly opens and closes the valve seat 20a in accordance with the pressure of oxygen flowing into the air supply tank 24 to reduce the pressure of oxygen. Therefore, the first exhaust tank 25 and the second exhaust tank 26 can supply the decompressed oxygen.

Here, as described above, the valve piston 22 may include a trap portion 22b in the form of a groove. This trap 22b traps oxygen to concentrate the pressure of oxygen to the valve head 22a. Therefore, when the pressure of oxygen increases, the valve piston 22 can be easily moved in accordance with the collecting portion 22b.

Referring to Figure 6, the piston spring 23 resiliently supports the valve piston 22. One side of the piston spring 23 is inserted into the spring insertion groove 27 formed on the other side of the valve piston 22, and the other side is inserted into the outer peripheral surface of the first spring piece 28 which is formed to protrude from the decompression cylinder 21, thereby elastically supporting the valve Piston 22. The piston spring 23 expands and contracts according to the movement of the valve piston 22 as described above.

Referring to Fig. 7, the air supply control valve 30 provides a moving path of oxygen supplied from the aforementioned pressure reducing valve 20, thereby opening or closing the moving path to control the flow of the air supply. The air supply control valve 30 includes a valve housing 31, a valve plunger 32, and a plunger spring 33.

The valve housing 31 is provided with a moving path of oxygen constituted by a supply orifice 34 and a discharge orifice 35, the supply orifice 34 receives oxygen supplied from the pressure reducing valve 20, and the discharge orifice 35 discharges the supply to the supply orifice 34. Oxygen is supplied to the flow control valve 40. At this time, as shown in FIG. 4, the supply port 34 is connected to the pressure reducing valve 20 through the first flow path D1 to receive oxygen. Further, the discharge port 35 is connected to the flow rate control valve 40 via the third flow path D3 as shown in FIG. 4 .

The valve plunger 32 is movably built in the valve housing 31 along the longitudinal direction, and moves in the longitudinal direction in the valve housing 31 to open and close the supply orifice 34 or the discharge orifice 35. At this time, the valve plunger 32 is provided with a first O-ring 36 on the outer circumferential surface of the front end of the opening and closing supply and discharge orifices 34, 35, thereby sealing the front end side.

The plunger spring 33 elastically supports the valve plunger 32 in the valve housing 31, one side being supported by the valve plunger 32 and the other side being supported by a spring support bracket 37 formed inside the valve housing 31. Such a plunger spring 33 is provided to pressurize the valve plunger 32 toward the inner side of the valve housing 31. That is, the valve plunger 32 is elastically supported to be biased to one side. Therefore, the valve plunger 32 is normally positioned on one side of the valve housing 31 in accordance with the elastic force of the plunger spring 33 as shown in the drawing, and maintains the open state of the supply and discharge orifices 34, 35.

Referring to Fig. 8, inside the air supply control valve 30, oxygen is supplied through the first flow path D1 connecting the pressure reducing valve 20 and the supply port 34, and the inflowing oxygen is supplied to the flow rate control valve 40 through the discharge port 35. . When the valve plunger 32 faces the valve housing 31 and the oxygen of the pressure reducing valve 20 flows into the supply hole 38 to be described later through the sixth flow path D6, the air supply control valve 30 compresses the column according to the oxygen pressure of the supply hole 38. The spring 33 is moved to move. At this time, the valve plunger 32 shields the discharge orifice 35 from the oxygen supplied to the inside of the flow rate control valve 40 through the third flow path D3.

Here, the supply hole 38 described above is connected to the operation control valve 101 through the sixth flow path D6 as illustrated in FIG. 4 . At this time, one end of the sixth flow path D6 is connected to the supply hole 38 of the air supply control valve 30, and the other end is connected to the discharge tank 115 of the operation control valve 101, and the supply hole 38 is communicated with the operation control valve 101.

Referring to FIG. 9, the flow control valve 40 includes a valve cylinder 41, a flow regulating valve member 42, a knob 43, and a connector 44.

The valve cylinder 41 has a supply hole 45 for receiving oxygen from the air supply control valve 30 and a discharge hole 46 for discharging supplied oxygen, and a valve seat 47 is provided between the supply hole 45 and the discharge hole 46. At this time, the supply hole 45 is connected to the third flow path D3 connected to the discharge port 35 of the air supply control valve 30, and the discharge hole 46 is connected to the supply air flow path 60 through the fourth flow path D4.

The flow rate adjusting valve member 42 is movably built in the valve cylinder 41 up and down, and moves up and down according to the rotational force supplied from the external knob 43, thereby changing the interval from the valve seat 47, and adjusting the oxygen discharged to the discharge hole 46. Discharge flow. That is, the flow rate adjusting valve member 42 and the knob 43 directly interlock.

The knob 43 is rotatably fixed to rotate outside the outer casing 10 to provide a rotational force to the flow regulating valve member 42. At this time, the knob 43 is provided with a pointer, and the surface of the outer casing 10 that the knob 43 rotates can display the weight or the like. Therefore, a suitable oxygen supply amount can be set according to the weight of the patient by rotating the knob 43. (not shown)

Here, the supply amount of oxygen is set in advance in accordance with the amount of oxygen required for dataization according to the body weight, and such a technique is a technique well known in the art, and thus a detailed description thereof will be omitted.

Further, the connector 44 connects the knob 43 to the flow regulating valve member 42 such that the knob 43 and the flow regulating valve member 42 interlock with each other.

Referring to FIG. 10, the connector 44 includes a rotating ring 48, a fastener, an insertion protrusion 50, and a projection holder 51.

The rotating ring 48 is integrally fixed to the flow regulating valve member 42 and rotates together with the flow regulating valve member 42. Also, the fastener detachably secures the rotating ring 48 to the flow regulating valve member 42.

Here, the fastener is composed of a cutting portion 52, isolation projections 53, 53a, and a rotating ring coupling member. The cutting portion 52 is cut by a part of the rotating ring 48 inserted into one side of the flow rate adjusting valve member 42, and is provided in the same shape to the rotating ring 48. The isolation protrusions 53, 53a are respectively protruded from a part of the rotating ring 48 at both ends of the cutting portion 52 to form a state of being isolated from each other. The rotating ring coupling member is coupled to the isolation protrusions 53, 53a to reduce the isolation width of the isolation protrusions 53, 53a, that is, to reduce the inner diameter of the rotating ring 48 to fix the rotating ring 48 to the flow regulating valve member 42. At this time, the rotating ring coupling member may be constituted by bolts 54 of various forms as shown in the drawing, and the coupling protrusions 53 and 53a are formed with coupling holes 55 that are screwed to the bolts 54 to be coupled to each other.

According to such a rotating ring coupling member, the rotating ring 48 can be easily detachably fixed to the flow regulating valve member 42 by screwing. In particular, as the surface of the flow regulating valve member 42 does not directly contact the bolt 54 of the rotating ring coupling member, the rotating ring 48 is fixed in a non-contact manner, and it is possible to prevent the groove of the flow regulating valve member 42 from being generated by the bolt 54. Form scratches. That is, the end of the bolt 54 is coupled to the outer peripheral surface of the flow regulating valve member 42 together with the stop screw, and when the outer peripheral surface is pressurized, the groove can be formed by the end of the bolt 54, or the bolt 54 is not in direct contact. The outer peripheral surface of the flow rate adjusting valve member 42 is not formed with a groove, and is coupled to the partitioning projections 53, 53a located on the side of the flow regulating valve member 42. Therefore, when it is necessary to adjust the set angle of the rotating ring 48, the bolt 54 is re-released, and after adjusting the set angle of the rotating ring 48, the coupling ring 53, 53a is re-coupled to fix the rotating ring 48 to the adjusted position.

If the bolt 54 is coupled to the flow regulating valve member 42 together with the stop screw as described above, the bolt 54 is difficult to rejoin the position adjacent to the first combined position. Because, when the bolt 54 is first joined, the end portion is formed with a groove on the outer peripheral surface of the flow regulating valve member 42, and the end portion is reinserted into the first formed groove even if rejoined to a position adjacent to the first joining position. However, in the present invention, since the bolts 54 are laterally provided on the side of the flow rate adjusting valve member 42 as described above, the surface of the flow rate adjusting valve member 42 is not formed with a groove, and can be reattached to a desired position at any time.

Further, another pad (not shown) may be interposed between the rotating ring 48 and the flow rate adjusting valve member 42, in order to improve the bonding force and suppress the occurrence of scratches.

Further, the fitting projection 50 of the connector 44 is formed to protrude from the side of the rotating ring 48 toward the knob 43 in a vertical state. At this time, the fitting projection 50 is preferably formed in the second side flap 57 of the stopper described later, and the projection holder 51 is provided inside the knob 43 in the form of a groove. Therefore, the fitting projections 50 are inserted into the projection holder 51 and fixed in the hanging state and connected to each other, so that the rotational force generated when the knob 43 is rotated can be easily supplied to the flow rate adjusting valve member 42 in addition to the easy connection.

The connector 44 may be provided with a stopper for controlling the rotation angle of the knob 43. The stopper is formed by being protruded from both sides of the rotating ring 48 and rotating together with the rotating ring 48 and contacting the fixing member located at the periphery of the outer side of the rotating ring 48, and suppressing the rotation of the knob 43 at a set angle. The first and second side wings 56, 57 are formed. At this time, the fixing member may be applied to the air supply pipe 61 provided to the air supply path 60 or the overflow unit 90 coupled to the air supply pipe 61, which is disposed inside the outer casing 10.

Such a limit member may include a fixing member, that is, a spacer provided to contact one of the first and second side flaps 56, 57 of the air supply pipe 61. In the embodiment of the present invention, the spacer is disposed on the second side wing 57 as an example.

The spacer adjusts the separation distance between one side of the second side wing 57 and the air supply pipe 61, and additionally controls the rotation angle of the knob 43 according to the limiting element. That is, the shim screw is coupled to one side of the second side wing 57 to be protrudedly fixed, and preferentially contacts the outer side of the air supply pipe 61 or the overflow unit 90 than the side of the rotating second side wing 57.

The spacer may be constituted by a bolt 58 and coupled to the bolt hole 58a formed in the second wing 57 to advance and retreat. At this time, the bolt 58 can be constituted by a headless bolt, smoothly advances with the bolt hole 58a, and retreats and protrudes to one side.

Such a gasket protrudes toward the air supply pipe 61 or the overflow unit 90 side along the bolt hole 58a according to the operation of the user, and the air supply pipe 61 or the second wing 57 of the overflow unit 90 can be finely adjusted. Isolation distance L. Therefore, the spacer adjusts the error range exceeding the range of the set rotation angle of the knob 43 by adjusting the separation distance L. That is, the rotation angle of the knob 43 is erroneous due to the use of continuous rotation, etc., and an error in the rotation angle of the flow path is generated, and an error in the rotation angle is generated in accordance with the manufacturing dispersion or the assembly dispersion in the production process of the component. At this time, the rotation angle error range of the knob 43 can be adjusted by rotating the bolt 58 to shorten or reduce the separation distance L of the air supply pipe 61 or the second wing 57 of the overflow unit 90.

As a result, the spacer can prevent the phenomenon that the supply of oxygen to the flow control valve 40 connected to the knob 43 is excessive or less than the set value by adjusting the error range according to the rotation angle of the knob 43, and can more precisely control the orientation. The amount of oxygen supplied by the flow control valve 40 is described. Also, the gasket easily adjusts the amount of oxygen supplied to the flow control valve 40 to a desired flow rate by adjusting the aforementioned separation distance L. Therefore, the flow control valve 40 can be precisely controlled by the spacer, and the amount of oxygen supplied to the patient can be precisely adjusted.

Here, the spacer is composed of a plurality of bolts 58 and is illustrated by a solid line and a broken line. When the first and second side flaps 56 and 57 are simultaneously provided, the rotation angles of the knobs 43 in both directions can be controlled. That is, the bolts 58 can respectively control the rotation angles of the positive rotation and the reverse rotation of the knob 43. Therefore, the knob 43 can easily adjust the highest point and the lowest point of oxygen supplied to the flow control valve 40 by the bolts 58.

Further, the supply air passage 60 receives oxygen from the flow control valve 40 and is guided to the discharge port 12 of the outer casing 10. This supply air passage 60 is formed inside the discharge port 12 of the outer casing 10 through a vertically disposed air supply pipe 61, and supplies oxygen to the breathing mask 13 connected to the discharge port 12.

Referring to Fig. 11, an artificial respiration apparatus according to an embodiment of the present invention further includes an overflow unit 90 that discharges a portion of oxygen guided to the discharge port 12 of the outer casing 10 through the supply air passage 60 to the outside.

This overflow unit 90 can be formed by the trap chamber 91 and the pressure reducing valve 92. The trap chamber 91 collects oxygen that has overflowed through the air supply path 60 and discharges it to the exhaust hole 93 provided on one side. At this time, in order to prevent interference of the knob 43, as shown, the trap chamber 91 is preferably provided on one side of the knob 43. The pressure reducing valve 92 is attached to the upper side of the exhaust hole 93 of the collecting chamber 91, and opens and closes the exhaust hole 93 in accordance with the pressure of the oxygen trapped in the trap chamber 91.

Here, the aforementioned pressure reducing valve 92 may include a valve disc 95, a disc supporting spring 96, and a second spring piece 97. The valve disk 95 is formed of a general diaphragm. As shown in the figure, the second spring piece 97, which will be described later, is assembled by the male and female screws 97a coupled to each other to shield the vent hole 93 of the trap chamber 91. . As shown, the disk support spring 96 is restrained from being detached by the second spring piece 97 on one side, and the valve disk 95 is elastically supported by the valve disk 95 by the other side of the opposite side.

The pressure reducing valve 95 may be provided with a spring adjuster 94 that adjusts the elastic force of the disk supporting spring 96 by moving the second spring piece 97. The spring adjuster 94 is lifted (moved), for example, in order to rotate the second spring piece 97. As shown, the second spring piece 97 is preferably movably screwed to the chamber box 91a or the outer casing 10 of the trap chamber 91. The components of the screw are constructed. That is, the spring adjuster 94 may be constituted by a male screw formed on the outer peripheral surface of the second spring piece 97 and a female screw formed in the chamber case 91a.

The second spring piece 97 is constituted by a screw member as the spring adjuster 94 is rotatable with the turnbuckle of the spring adjuster 94. At this time, the second spring piece 97 expands and contracts the disk support spring 96 by raising and lowering, and adjusts the elastic force of the disk support spring 96. Therefore, the pressing force of the disc support spring 96 pressing valve disc 95 is adjusted.

Referring to Fig. 12, in the overflow unit, when oxygen overflows above the set value inside the trap chamber 91, the pressure inside the trap chamber 91 rises, and the valve disc 95 moves upward according to the rising pressure. The vent hole 93 is opened, and the overflowed oxygen is discharged to the outside through the through hole H formed in the second spring piece 97 or the chamber case 91a. At this time, the valve disk 95 trembles according to the oxygen of the exhaust gas, and emits an alarm sound of "啵鲁鲁~~".

Thereafter, when the internal pressure of the trap chamber 91 is lowered to the set value level according to the oxygen discharged to the outside, the valve disc 95 returns to the original state according to the elastic restoring force of the disc support spring 96, and the trap chamber is again shielded. The vent hole 93 of 91.

Here, when the pressure of the second spring piece 97 in the collection chamber 91 is a set value, in order to operate the valve disk 95, the disk spring is lifted and pressed by the screw spring adjuster 94. 96, thereby adjusting the elastic force of the disc spring 96. Therefore, the valve disc 95 operates only at the set pressure.

In addition, referring to FIGS. 4 and 9, the artificial respiration apparatus according to an embodiment of the present invention may further include an operation control unit that controls the operation of the air supply control valve 30 according to the pressure of the oxygen supplied to the flow control valve 40. .

Such an operation control unit can be constituted by the bypass valve 100 and the operation control valve 101. The bypass valve 100 bypasses a portion of the oxygen supplied to the flow control valve 40 through the air supply control valve 30 to the outside. Further, the operation control valve 101 is operated based on the oxygen bypassed from the bypass valve 100, and the oxygen decompressed from the portion supplied from the pressure reducing valve 20 is supplied to the air supply control valve 30 to be partially depressurized by oxygen control. The operation of the air supply control valve 30.

The bypass valve 100 may be composed of an oxygen filling chamber 102 and a tilt valve member 103. The oxygen filling chamber 102 is provided below the flow rate control valve 40 and includes a communication hole 104 that communicates with the flow rate control valve 40. The oxygen filling chamber 102 is filled with a part of oxygen supplied to the flow rate control valve 40 through the communication hole 104, and has a bypass hole 105 that bypasses the supply of the supplied oxygen to the operation control valve 101. At this time, the bypass hole 105 is connected to the operation control valve 101 through the bypass flow path 106.

Here, the oxygen filling chamber 102 can be formed integrally with the valve cartridge 41 of the flow control valve 40 as shown.

The tilt valve member 103 is movably built up inside the oxygen filling chamber 102, and forms an inclined surface 107 to move to the inside of the communication hole 104, thereby changing the cross-sectional area of the communication hole 104. The tilt valve member 103 can be manufactured in a conical shape as illustrated in the drawings, and the outer peripheral surface can form an inclined surface 107 that can be elastically supported by the support spring 108.

One side of the support spring 108 is inserted into the spring insertion end 108a which is formed to protrude from the lower portion of the inclined valve member 103, and the other side is inserted into the third portion which is formed to protrude from the inside of the oxygen filling chamber 102 and is opposed to the spring insertion end 108a. Spring piece 108b.

Here, in the above-described tilt valve member 103, the tip end of the inclined surface 107 is in close contact with the flow rate adjusting valve member 42 of the flow rate control valve 40 through the communication hole 104, and is interlocked and moved according to the above-described knob 43 (lifting and lowering) The flow regulating valve member 42 is pressurized. Therefore, the tilt valve member 103 compresses and moves the support spring 108 in accordance with the pressing force, and returns to the home position in accordance with the restoring force of the support spring 108.

Referring to Fig. 13, the operation control valve 101 is formed by a valve chest 110, a bobbin 111, and a bobbin spring 112.

One side of the valve chamber 110 forms a bypass tank 113 connected to the bypass flow path 106 and flows into the bypass oxygen of the bypass valve 100. The other side of the valve chamber 110 is arranged side by side with an inflow tank 114 that flows in oxygen supplied from the pressure reducing valve 20 and decompressed by the air supply control valve 30, and discharges the inflowing portion of the decompressed oxygen to the air supply control valve 30. Discharge tank 115. At this time, the inflow tank 114 is connected to the second discharge port 34a of the air supply control valve 30 through the fifth flow path D5. Further, the discharge tank 115 is connected to the supply hole 38 formed on one side of the air supply control valve 30 through the sixth flow path D6. Such a valve chamber 110 may be provided with a venting opening 116 that communicates with the discharge tank 115 to discharge a portion of the decompressed oxygen supplied to the discharge tank 115.

The bobbin 111 is built in the valve chamber 110, moves according to the bypass oxygen flowing into the bypass tank 113, and communicates or isolates the inflow tank 114 and the discharge tank 115 through the bobbin shoulder of the outer peripheral surface. At this time, the bobbin lifting shoulder may be configured as a plurality of second O-rings 117 which are mounted in an isolated state on the outer circumferential surface of the bobbin 111, and may be applied to the outer circumference of the bobbin 111 in a concavo-convex shape. Any structure that flows into the tank 114 and the discharge tank 115 can be opened and closed.

Further, the bobbin spring 112 elastically supports the bobbin 111 inside the valve chamber 110, and one side and the other side are supported by the fourth spring pieces 118, 118a formed on the bobbin 111 and the valve chamber 110, respectively.

Referring to Fig. 14, after the oxygen of the air supply control valve 30 flows into the inside of the valve chamber 110 along the bypass flow path 106 through the bypass valve 100, the bobbin 111 moves to one side according to the pressure thereof, thereby being connected and opened and closed. The inflow tank 114 and the discharge tank 115. At this time, the open inflow tank 114 supplies the oxygen supplied from the air supply control valve 30 to the connected discharge tank 115 through the fifth flow path D5, and is re-supplied to the air supply by the sixth flow path D6 connected to the discharge tank 115. Control valve 30.

That is, the supplied oxygen is guided to the supply port 38 of the air supply control valve 30 through the discharge can 115 opened together with the inflow tank 114, thereby pressurizing the valve plunger 32 of the air supply control valve 30 to move to one side. The supply and discharge orifices 34, 35 are closed.

Referring to Fig. 15, an artificial respiration apparatus according to an embodiment of the present invention may further include a manual control valve 70 that directly supplies oxygen supplied through a second flow path D2 connected to a second exhaust tank 26 of the pressure reducing valve 20 to Air flow path 60.

Such a manual control valve 70 can be constituted by a manual valve casing 71, an opening and closing member 72, an elastic body 73, and a trigger 74.

One side of the manual valve box 71 is provided with an input hole 75 that is connected to the second flow path D2 and continuously receives oxygen decompressed by the pressure reducing valve 20; the other side is provided with an output hole 76 that discharges into the input hole 75. oxygen. At this time, the output hole 76 is connected to the above-described supply air passage 60 through the seventh flow path D7.

The opening and closing member 72 is movably built in the manual valve box 71 up and down, thereby opening and closing at least one of the input hole 75 and the output hole 76.

The elastic body 73 elastically supports the opening and closing member 72, and may be constituted by a coil spring as shown in the drawing, and the one side and the other side are supported by the fifth spring pieces 77, 77a respectively formed in the manual valve box 71 and the opening and closing member 72.

The trigger 74 is rotatably provided on the lower side of the opening and closing member 72 with reference to the switch point H1 formed on the lower portion of the manual valve case 71, and presses the opening and closing member 72 supported by the elastic body 73 to the upper side by rotation. The output aperture 75 is open.

The upper end portion of the switch point H1 of the trigger 74 abuts against the lower end of the opening and closing member 72, and an inclined surface is formed on the end portion that is in close contact with each other, and the opening and closing member 72 is pressed to the upper portion by sliding when rotating.

Referring to Fig. 16, the end portion of the trigger 74 that abuts the opening and closing member 72 is formed with a cam groove 78 formed by an inclined surface, and the lower end of the opening and closing member 72 that is in contact therewith forms a cam module 78a that is in cam contact with the cam groove 78. .

Referring to Fig. 17, when the user holds the trigger 74 and rotates with reference to the switch point H1, the opening and closing member 72 pressurizes and compresses the elastic body 73 and moves upward to open the output hole 76. At this time, the oxygen that has flowed into the input hole 75 along the second flow path D2 and is filled into the inside of the manual valve box 71 is discharged to the open output hole 76. Therefore, the output hole 76 supplies oxygen to the supply air passage 60 through the seventh flow path D7.

Thereafter, after the user releases the gripping force of the trigger 74, the trigger 74 returns to the original state in accordance with the restoring force of the compressed elastic body 73, and the opened output hole 76 is closed.

Further, a sealing material 79 may be provided between the manual valve box 71 and the opening and closing member 72. The sealing material 79 is provided to prevent oxygen which is normally input through the input hole 75 from being supplied to the output hole 76 side. At this time, the sealing material 79 is provided as a washer or an O-ring or the like, and one side can be fixed to the manual valve box 71 or the opening and closing member 72.

Next, the operation of the artificial respiration apparatus having the above configuration will be described with reference to the drawings.

First, the outer casing 10 of the artificial respiration apparatus according to the embodiment of the present invention is connected to the oxygen tank through the supply port 11, and is connected to the patient's respirator by the user in a state where the breathing mask 13 is provided on the discharge port 12.

After the connection is completed, the user rotates the knob 43 to the set value according to the state of the patient, that is, the age or weight, and supplies the patient with an appropriate amount of oxygen. That is, referring to the foregoing drawings and FIG. 17, the artificial respiration apparatus according to the embodiment of the present invention supplies the oxygen of the oxygen tank to the inside of the casing 10 in a reduced pressure state from the state of FIG. 4 through the pressure reducing valve 20. At this time, as shown in FIG. 5 and FIG. 6, the pressure reducing valve 20 repeatedly moves the valve piston 22 according to the oxygen pressure, and reduces the pressure of the oxygen to supply the oxygen flowing into the air supply tank 24 to the first or second. Exhaust tanks 25, 26. Therefore, the pressure reducing valve 20 supplies the decompressed oxygen to the air supply control valve 30 through the first flow path D1 as illustrated in FIG. 4 .

Further, the oxygen supplied to the air supply control valve 30 is supplied to the flow rate control valve 40 along the third flow path D3 as illustrated in FIG. 4 . At this time, the oxygen supplied to the flow control valve 40 side is supplied to the supply air passage 60 along the fourth flow path D4, thereby being supplied to the patient through the respiratory mask 13.

Further, a part of the oxygen supplied to the flow control valve 40 side flows into the bypass valve 100 as shown in FIG. 4 and bypasses the bypass flow path 106 to the operation control valve 101 side. At this time, the operation control valve 101 gradually increases in the amount of oxygen supplied, and the bobbin 111 is gradually moved to one side as illustrated in FIG. 14 to finally open the inflow tank 114 and the discharge tank 115 of the operation control valve 101. .

Further, as described above, before or during the movement of the bobbin 111, a part of the oxygen supplied from the pressure reducing valve 20 to the air supply control valve 30 through the first flow path D1 passes through the second discharge hole of the air supply control valve 30. The port 34a is supplied to the fifth flow path D5 as illustrated in FIGS. 4 and 17, and flows into the inflow tank 114 of the operation control valve 101 through the fifth flow path D5, and is supplied to the operation control valve 101. Further, as shown in FIG. 14, the oxygen flowing into the inflow tank 114 is re-supplied to the sixth flow path D6 connected to the discharge tank 115 as shown in FIG. The supply port 38 of the gas control valve 30. At this time, the oxygen supplied to the air supply control valve 30 along the sixth flow path D6 is as shown in FIG. 8, and the valve plunger 32 of the air supply control valve 30 is pressurized to move, and the discharge port 35 of the air supply control valve 30 is closed. . Therefore, the air supply control valve 30 isolates the oxygen supplied to the flow control valve 40, so that a person breathing through the breathing mask 13 can inhale (exhale).

As described above, when the operation of the air supply control valve 30 is interrupted, the oxygen filled in the valve chamber 110 according to the bypass valve 100 in the operation control valve 101 reflows through the bypass flow path 106 as illustrated by the broken line in Fig. 17 . After the bypass valve 100 is guided to the flow rate control valve 40 through the communication hole 104 of the bypass valve 100, it is guided to the air supply pipe 61 and discharged through the fourth flow path D4 connected to the flow rate control valve 40. At this time, as the bobbin 111 built in the valve chamber 110 is returned to the home position as illustrated in FIG. 13 according to the bobbin spring 112, the oxygen filled in the valve chamber 110 is supplied to the bypass valve 100 according to the pressing force of the bobbin 111, Since the bypass tank 113 of the valve chamber 110 is narrow and the density inside the valve chamber 110 is excessively large, it is gradually discharged to the bypass tank 113 and supplied to the bypass valve 100.

Further, when the bobbin 111 described above is returned to the original position as illustrated in FIG. 13, as shown, the discharge tank 115 and the vent hole 116 of the valve chamber 110 described above communicate with each other. At this time, as shown in FIGS. 8 and 17, the oxygen from the discharge tank 115 of the valve chamber 110 is supplied to the air supply control valve 30 through the sixth flow path D6 to pressurize the valve plunger 32 as shown by the broken line in FIG. It is shown that it returns to the discharge tank 115 along the sixth flow path D6, and is discharged to the outside through the vent hole 116. Therefore, as the pressure of the oxygen of the pressure valve plunger 32 is released, the air supply control valve 30 returns to the original state, that is, the state of FIG.

As the pressure is released and the valve plunger 32 is restored, as illustrated in Fig. 7, the discharge orifice 35 of the air supply control valve 30 is reopened. Therefore, as shown in FIG. 4, the air supply control valve 30 re-supplies oxygen to the flow rate control valve 40 and the bypass valve 100 through the third flow path D3, and restarts the operation for breathing as described above.

According to the artificial respiration apparatus of the embodiment of the present invention, oxygen is re-supply after the patient is supplied with oxygen or interrupted by the respiratory cycle by repeating the aforementioned series of processes, that is, the state of FIG. 4 and the state of FIG.

Further, when the oxygen concentration in the air supply pipe 61 is excessively large, the overflow unit discharges the dense oxygen through the pressure reducing valve 92 as illustrated in FIG. Therefore, the overflow unit can prevent excessive supply of oxygen to the human body.

In addition, if the components fail, that is, when the air supply control valve 30, the operation control valve 101, and the flow control valve 40 fail, or when the cardiac massage CPR is performed, the user operates the manual control valve 70 to stop the automatic operation. Breathe and convert to manual to manually supply oxygen to the patient.

To explain this in more detail, a part of the oxygen supplied to the pressure reducing valve 20 is supplied to the manual valve box 71 through the second flow path D2 connected to the second exhaust tank 26. At this time, the user rotates the trigger 74 of the manual control valve 70 as shown in FIG.

As a result, as shown in FIG. 16, the oxygen that has flowed into the input port 75 connected to the second flow path D2 and is filled in the manual valve box 71 is directly supplied to the supply flow path 60 along the seventh flow path D7 through the open output hole 76. , thus supplied to the patient.

Thus, according to the artificial respiration apparatus of the embodiment of the present invention, oxygen can be smoothly supplied to the patient by manually controlling the valve 70 during an emergency or a cardiopulmonary resuscitation due to a failure of a part of the component.

Further, the above-described operation control unit may include a pressurizing chamber 140 as illustrated in FIGS. 4 and 17 . The pressurizing chamber 140 is a hermetic outer casing having a filling space therein. The pressurizing chamber 140 is provided in a flow path connecting the bypass valve 100 and the operation control valve 101, and pressurizes the oxygen supplied from the bypass valve 100 to the operation control valve 101.

As shown in FIGS. 4 and 17, the pressurizing chamber 140 is provided in the bypass flow path 106 that connects the bypass valve 100 and the operation control valve 101. At this time, as shown in the drawing, the pressurizing chamber 140 may be provided in a single manner on the bypass flow path 106, or may be provided in plurality differently from the illustration, and may be sequentially disposed along the bypass flow path 106. One side of the pressurizing chamber 140 is connected to the bypass valve 100 through a flow path, the other side is connected to the operation control valve 101 through a flow path, and oxygen supplied through the bypass valve 100 is filled along the bypass flow path 106. Go inside it.

As described, when the pressurized chamber 140 refills the oxygen from the bypass valve 100 after filling the oxygen of the bypass valve 100, the newly supplied oxygen pressurizes the filled oxygen due to the excessive density of the internal oxygen. At this time, the pressure chamber 140 is naturally increased due to an excessively high oxygen density, and the oxygen first filled into the inside is discharged to the operation control valve 101. Further, the oxygen gas discharged from the pressurizing chamber 140 to the operation control valve 101 is supplied to the operation control valve 101 by the other pressurizing chamber 140 and whose pressure is excessively increased and its pressure is maintained from rising to rising. Therefore, the operation control valve 101, as illustrated in FIG. 9, supplies a small amount of oxygen even through the bypass hole 105 of the bypass valve 100, as supplied with oxygen doubled according to the pressure of the pressurizing chamber 140, as shown in FIGS. 13 and 14. As shown in the figure, the inner bobbin 111 can be smoothly operated.

In addition to this, as shown in FIG. 18, the supply air passage 60 guides the flow of oxygen to the inside, that is, the flow rate of oxygen supplied to the breathing mask 13, by the flow rate variable unit FV. As will be described later, when the user exhales, the oxygen supplied from the supply air passage 60 to the respiratory mask 13 is discharged to the outside to interrupt the supply of oxygen, and when the user inhales, the oxygen is exhausted. The breathing mask 13 re-supplies oxygen. That is, when the flow rate variable unit FV exhales, the breathing mask 13 is exhausted to the outside to interrupt the supply of oxygen, so that the user can discharge the air, and when inhaling, the oxygen is supplied to the respiratory mask 13 again, so that the user can reabsorb. oxygen. Thereby, the supply air passage 60 controls the flow rate of oxygen supplied to the breathing mask 13 by the flow rate variable unit FV.

As described above, the reason why the flow rate variable unit FV discharges the oxygen that is guided to the respiratory mask 13 through the air supply path 60 during exhalation is that the oxygen is supplied to the respiratory mask 13 through the air supply path 60 when the user exhales. The discharged carbon dioxide cannot be discharged through the exhaust valve (check valve) of the breathing mask 13 due to the pressure of the oxygen supplied to the breathing mask 13, and vortex is generated to be re-supplied to the user when the user inhales, so in order to prevent this It is a phenomenon. Therefore, if the flow rate variable unit FV is provided, the user does not breathe carbon dioxide at the time of exhalation.

The flow rate variable unit FV, as illustrated in FIG. 19, includes a dump valve 160 and a switching valve 150. As shown in FIGS. 18 and 19, the bleed valve 160 includes a drain hole 160a that communicates with the air supply path 60, and opens and closes the drain hole 160a to discharge at least a part of the oxygen gas guided through the air supply path 60 or to isolate the exhaust gas. As shown in the figure, the drain valve 160 can communicate with the supply air passage 60 through the twelfth flow path D12. However, the drain valve 160 can be integrally attached to the supply air passage 60. That is, the bleed valve 160 is connected to the supply air passage 60, thereby receiving oxygen from the supply air passage 60 and exhausting it through the drain hole 160a.

The bleed valve 160, as illustrated in FIG. 19, may include a drain body 161, an opening and closing mass 163, and a drain spring 165. As shown in the figure, the excretion main body 161 has the above-described drain hole 160a on one side and the oxygen supply passage 60 through the other side through the other side. That is, the excretion body 161 can discharge the oxygen supplied to the air supply path 60 through the other side through the drain hole 160a on one side. The drain hole 160a of the excretion body 161 may be formed at various positions, but is preferably formed on the side as illustrated.

The opening and closing group 163 is movably built in the excretion body 161 as illustrated in FIGS. 18 and 19 . As shown in FIGS. 19 to 21, the opening and closing group 163 moves and opens and closes the drain hole 160a in accordance with oxygen supplied to the switching valve 150 of the drain main body 161. As shown in the figure, the opening and closing group 163 is preferably configured as a lift valve member, and can open and close the drain hole 160a formed on the side of the drain body 161. The opening and closing group 163 moves and closes the drain hole 160a of the drain body 161 in accordance with the pressure of oxygen flowing into the drain body 161 through the switching valve 150 as illustrated in FIG. At this time, in the drain main body 161, oxygen flows into the first flow path D11 connected to the oxygen supply hole P2 of the switching valve 150.

As shown in FIGS. 18 and 19, the drain spring 165 is built in the excretion body 161 to elastically support the opening and closing group 163. The drain spring 165 is compressed according to the movement of the opening and closing group 163 as illustrated in FIG. Further, when the oxygen supplied to the excretion body 161 is isolated, as shown in FIG. 21, the drain spring 165 returns and returns the opening and closing group 163 to the home position. Therefore, the opening and closing group 163 opens the drain hole 160a of the excretion body 161.

The switching valve 150 awards oxygen supplied from the pressure reducing valve 20 to the bleed valve 160 to operate the bleed valve 160. Such a switching valve 150 is capable of directly receiving oxygen from the pressure reducing valve 20, but is preferably configured to be supplied to the bleed valve 160 by the oxygen supply of the pressure reducing valve 20 through the aforementioned air supply control valve 30 as illustrated in FIG. At this time, as shown in FIG. 18, the air supply control valve 30 causes the oxygen supplied from the pressure reducing valve 20 to the valve housing 31 to be supplied to the switching valve 150 by additionally adding the additional hole 35a formed in the valve housing 31. Therefore, the switching valve 150 can cause the air supply control valve 30 to interlock with the bleed valve 160.

On the other hand, as shown in FIGS. 22 and 23, the switching valve 150 receives the oxygen of the pressure reducing valve 20 through the aforementioned manual control valve 70 and supplies it to the bleed valve 160. Therefore, the switching valve 150 can cause the manual control valve 70 to interlock with the bleed valve 160.

As shown in FIGS. 18 and 19, the switching valve 150 includes a needle housing 151, a needle 153, and a needle spring 155. As shown in the figure, the needle housing 151 is coupled to the tenth flow path D10 connected to the above-described additional hole 35a of the air supply control valve 30, and flows into the oxygen inflow hole P1 of the oxygen supplied from the pressure reducing valve 20 through the air supply control valve 30. Formed on one side. That is, oxygen flows into the needle housing 151 through the oxygen inflow port P1 connected to the tenth flow path D10. Further, the needle housing 151 communicates with the oxygen inflow hole P1 as shown by an arrow in FIG. 19, and the other side is provided with an oxygen supply hole P2 for supplying oxygen flowing into the oxygen inflow hole P1 to the discharge valve 160. Therefore, the needle housing 151 substantially supplies the oxygen of the pressure reducing valve 20 to the bleed valve 160 to move the opening and closing group 163 of the bleed valve 160.

As shown in FIGS. 18 and 23, the needle housing 151 is formed with a filling hole P3, and flows into oxygen supplied to the pressure reducing valve 20 of the manual control valve 70 to be filled. Further, the needle housing 151 is formed as shown in the drawing so as to form a guide hole P4 in which a part of the oxygen supplied to the filling hole P3 is bypassed and guided. At this time, as shown in the figure, the filling hole P3 and the pilot hole P4 receive oxygen from the seventh flow path D7 of the oxygen supply valve 60 supplied from the manual control valve 70 to the supply air passage 60. Therefore, the manual control valve 70 includes a sixth flow path D8 that is branched from the seventh flow path D7 and connected to the filling hole P3 of the needle housing 151, and is connected to the needle housing from the eighth flow path D8. The ninth flow path D9 of the guide hole P4 of 151. Therefore, the filling hole P3 and the pilot hole P4 receive the oxygen of the manual control valve 70 through the eighth flow path D8 and the ninth flow path D9. However, the guide hole P4 is different from the above, and oxygen can be directly received from the seventh flow path D7.

As shown in FIGS. 19 and 23, the needle 153 is movably incorporated in the needle housing 151 to move, and opens and closes the oxygen inflow hole P1 or the oxygen supply hole P2 of the needle housing 151. As shown in FIG. 23, the needle 153 moves inside the needle housing 151 according to the pressure of oxygen flowing into the filling hole P3 of the needle housing 151, and opens and closes the oxygen inflow hole P1 or the oxygen supply hole P2. At this time, the needle 153 is opened as shown in the figure, and an O-ring is provided on the outer peripheral surface, and the oxygen inflow hole P1 or the oxygen supply hole P2 is opened and closed by the O-ring.

The needle 153 is normally fixed to the conventional position of the needle housing 151 as illustrated in FIG. 19, and communicates the oxygen inflow hole P1 and the oxygen supply hole P2 to supply the oxygen flowing into the oxygen inflow hole P1 to the discharge valve through the oxygen supply hole P2. 160. Therefore, as shown in the figure, the bleed valve 160 moves in accordance with the oxygen flowing into the drain main body 161 through the eleventh flow path D11, and the drain hole 160a is closed.

On the other hand, as shown in FIGS. 22 and 23, the needle 153 flows into the filling hole P3 and the guiding hole P4 of the needle housing 151, and moves and isolates the needle as shown in the figure according to the oxygen in the filling hole P3. The oxygen inflow hole P1 of the outer casing 151 is in communication with the oxygen supply hole P2. At this time, the needle 153 is in communication with the oxygen supply hole P2 as the O-ring is located between the oxygen inflow hole P1 and the oxygen supply hole P2 as shown. However, the needle 153 is shown by an arrow in FIG. 23, and communicates the oxygen flowing into the guide hole P4 through the oxygen supply hole P2 through the oxygen supply hole P2 through the guide hole P4 of the needle housing 151 and the oxygen supply hole P2 to the bleed valve 160. Therefore, as shown in the figure, the bleed valve 160 supplies oxygen to the drain main body 161 through the eleventh flow path D11, and the opening and closing mass 163 moves to close the drain hole 160a.

As shown in FIGS. 19 and 23, the needle spring 155 elastically supports the needle 153 inside the needle housing 151. As shown in FIGS. 19 and 21, the needle spring 155 supports the needle 153 by its own elastic force when oxygen is not supplied to the filling hole P3 of the needle housing 151, thereby preventing the movement of the needle 153. Further, as shown in Fig. 23, the needle spring 155 is compressed when oxygen is supplied to the filling hole P3 of the needle housing 151 and the needle 153 is moved, and the prototype is restored when the oxygen supply to the filling hole P3 of the needle housing 151 is blocked. The needle 153 is returned to the original position.

The flow rate variable unit FV configured as described above is supplied to the air supply path 60 by the flow rate control valve 40, as shown in FIG. At the time, the oxygen that has flowed into the supply port control valve 30 and is discharged to the additional hole 35a, that is, the partial oxygen that has flowed into the supply port 34 of the air supply control valve 30 and discharged to the discharge port 35 flows through the tenth flow path D10. Switching valve 150. At this time, the switching valve 150 is illustrated in Fig. 19, and the oxygen inflow hole P1 communicates with the oxygen supply hole P2 as the needle 153 is in the home position, and the oxygen which flows into the oxygen inflow hole P1 is directly supplied to the oxygen supply hole P2, through The eleventh flow path D11 supplies oxygen to the drain main body 161 of the bleed valve 160. Therefore, in the bleed valve 160, the opening and closing group 163 moves in accordance with the oxygen flowing into the drain main body 161, and the drain hole 160a is shielded.

Accordingly, the bleed valve 160 cannot discharge the oxygen supplied to the supply passage 60 through the flow control valve 40 as described above. Therefore, the supply air passage 60 continuously supplies the oxygen of the flow control valve 40 to the breathing mask 13 to allow the user to inhale.

However, as shown in FIG. 20, the switching valve 150 of the air supply control valve 30 is shielded together with the additional hole 35a, and the oxygen supply hole 40 cannot be supplied to the air supply path 60 through the flow rate control valve 40. P1 supplies oxygen, so as shown in FIG. 21, oxygen cannot be supplied to the drain main body 161 of the bleed valve 160. Therefore, the bleed valve 160 is opened to the drain hole 160a of the drain main body 161 in accordance with the opening and closing of the opening and closing member 163 by the drain spring 165 to return to the original position.

At this time, as shown in FIG. 20, the operation control valve 101 is filled with oxygen inside, that is, as illustrated in FIG. 14, and the inside of the pressure bobbin 111 is filled and the oxygen of the pressure bobbin 111 flows through the bypass flow path 106 as illustrated in FIG. After the bypass valve 100, the flow control valve 40 is supplied to the supply air passage 60 to be gradually exhausted through the supply air passage 60. The drain main body 161 discharges the oxygen that has passed through the operation control valve 101 discharged from the air supply path 60 through the drain hole 160a as shown in FIG. 21 as the drain hole 160a is opened as described above. Of course, as shown in FIG. 20, the drain hole 160a flows into the drain main body 161 through the 12th flow path D12 as the oxygen supplied to the air flow path 60, and discharges the oxygen supplied to the air flow path 60. Therefore, the supply air passage 60 does not supply oxygen to the breathing mask 13 at all. Therefore, when the user exhales through spontaneous breathing, the carbon dioxide is discharged to the respiratory mask 13. As described above, oxygen is not supplied to the respiratory mask 13, and eddy current due to interference of oxygen is prevented, so that when inhaling after exhalation, Inhale carbon dioxide again.

Further, when the air supply control valve 30 does not operate due to a failure or the like, the manual control valve 70 operates as described above and passes through the seventh flow path D7 as illustrated in FIG. 22 for the user's breathing. The oxygen of the valve 20 is supplied to the supply air passage 60. At this time, as shown in FIG. 22 and FIG. 23, the switching valve 150 flows into the filling hole P3 of the needle housing 151 through the eighth flow path D8 which is branched from the seventh flow path D7. Further, the switching valve 150 flows into the oxygen in the seventh flow path D7 to the guide hole P4 through the ninth flow path D9 that is branched from the eighth flow path D8.

As shown in FIG. 23, the switching valve 150 is moved by the needle 153 built in the needle housing 151 in accordance with the oxygen flowing into the filling hole P3 to isolate the oxygen inflow hole P1 from communicating with the oxygen supply hole P2. At the same time, the switching valve 150 supplies the oxygen flowing into the pilot hole P4 to the bleed valve 160 through the oxygen supply hole P2 through the oxygen supply hole P2 as shown in the drawing. At this time, the bleed valve 160 flows into the oxygen through the eleventh flow path D11, and as shown, the opening and closing group 163 moves again to close the drain hole 106a. Therefore, the supply air passage 60 is not discharged to the bleed valve 160 due to the oxygen inside the traverse, and the oxygen can be smoothly supplied to the breathing mask 13. Accordingly, the breathing mask 13 can continuously supply oxygen to a user who needs to inhale.

As a result, as shown in FIGS. 18 and 22, the flow rate variable unit FV that operates as described above supplies oxygen to the supply air flow path 60 according to the operation of the air supply control valve 30 for the user's intake, or according to manual control. When the valve 70 supplies oxygen to the supply air passage 60, the drain hole 160a of the drain valve 160 is closed to allow oxygen to be smoothly supplied to the breathing mask 13. Further, the flow rate variable unit FV does not supply oxygen to the respiratory mask 13 when the user exhales, and as shown in FIG. 20, opens the drain hole 160a of the bleed valve 160 to exhaust the oxygen flowing through the air supply path 60 to the outside.

The embodiments of the present invention have been described above, but the present invention is not limited to the embodiments described above, but includes all modifications within the scope of the equivalents that can be easily changed by those skilled in the art.
