At this time, the pressure reducing valve 20 by reducing the pressure of oxygen as the valve piston (22) moves repeatedly in accordance with the oxygen pressure, as illustrated in Figures 5 and 6. The oxygen from entering the air supply port 24 and it supplies it to the first or the second exhaust port (25, 26). Thus, the pressure reducing valve 20 to supply the oxygen pressure in the first flow path the air supply control valve 30 via the (D1), as shown in Fig.

Then, the oxygen supply to the air supply control valve 30 is in the air supply flow rate control valve 40 along the third flow path (D3) as shown in Fig. At this time, the oxygen supply side of the flow control valve 40 is the air supply to the air supply passage (60) along a fourth flow path (D4) are fed to a patient via a breathing mask (13).

On the other hand, the flow control valve 40, some very small amount of oxygen that the supply side is the side of the inlet to the bypass valve 100 includes a work control valve 101 along the bypass flow path 106 shown in Figure 4 by-pass it is. At this time, the operation control valve 101 presses the spool 111 as shown in Figure 14. With the increasing amount of the air supply the oxygen slowly while gradually move to one side of the spool 111, and finally operating the control valve (101 ) and opens the inlet port 114 and outlet port 115 of.

On the other hand, during the pre-movement or movement of the spool 111, the oxygen supplied to the air supply control valve 30 through the first flow path (D1) in the reduced-pressure valve 20 as described above, part of the air supply control valve 30, the second discharge after the as supplied to the fifth flow path (D5) shown in Figure 4 and shown in Fig. 17 through the orifice (34a), the inlet of the fifth operation control through a channel (D5) valve 101 of the flows to the port 114 is the air supply to the operating control valve 101. And, attached to the oxygen is, the discharge port 115 as shown in Figure 17. If communication with the inlet port 114, an exhaust port 115, as shown in Fig. 14 flows into the inlet port 114, the 6 along the flow path (D6) is again fed back to the supply hole 38 of the air supply control valve 30. In this case, the 6 along the flow path (D6) of oxygen supplied to the air supply control valve 30 is, as shown in Figure 8 while moving to urge the valve plunger 32 of the air supply control valve 30, the discharge of the air supply control valve 30 It closes the orifice 35. Accordingly, the air supply control valve 30 blocks the oxygen supplied to flow control valve 40 to allow a person to breathe through the breathing mask 13, the exhalation (expiration).

Thus, if the operation of the air supply control valve 30 is stopped, the operation control valve 101 by, as shown by a dotted line in 17 degrees of oxygen was charged into the valve chest 110 by the bypass valve 100 and then through the flow path 106 back to the inlet to the bypass valve 100 is guided to the flow control valve 40 through the communication hole 104 of the bypass valve 100, connected to the flow control valve (40) 4 is guided in rapid engine 61 through a flow path (D4) is discharged. At this time, the pressing force of the oxygen valve chest a split spool 111 as the 111 is spool spring returns to its original position as shown in Figure 13 by (112) embedded in the (110) filled in the valve chest 110 by is supplied to the by-pass valve 100, while gradually discharged to the by-pass port 113, as to the bypass port 113 of the valve chest 110, the narrow densely inside the valve chest 110 by-pass It is supplied to the valve 100.

On the other hand, when the above-mentioned spool 111, the case to return to the original position as described, the exhaust port 115 and the vent orifice 116 of the valve chest 110, described above, as illustrated shown in Figure 13 is in communication with each other. At this time, in the discharge port 115 of FIG. 8 and the valve chest 110, as shown in Figure 17 through the sixth yuro (D6) is supplied to the air supply control valve 30, oxygen was urging the valve plunger 32 , the sixth is along the flow path (D6) it returns again back to the exhaust port 115 is exhausted through the vent orifice 116 to the outside, as shown by a broken line in FIG. Accordingly, the air supply control valve 30 is in the original state i.e. as the pressure of the oxygen was urging the valve plunger 32 is released, it returns to the state of Fig.

Air supply control valve 30 is again a discharge orifice 35 as shown in Figure 7, opening pressure is released, as is the valve plunger 32 return. Accordingly, the air supply control valve 30, as illustrated in Figure 4 again, the third flow path (D3) via flow control valve 40 and the bypass valve to supply oxygen to 100 for respiration as discussed above carried out again to operate.

Such the ventilation apparatus according to an embodiment of the invention, the patient repeats the state in Fig. 17 and a series of processes described above that is, the state of Figure 4 Oxygen or oxygen again properly suspended in respiratory cycle .

On the other hand, the overflow unit when an oxygen-class engine 61 is impacted, the overcrowding of oxygen and exhaust through the relief valve 92 as shown in FIG. Thus, the overflow unit is to prevent the excessive oxygen is supplied to the human body.

On the other hand, if the failure of the parts occurs, that is performed when a failure, such as the air supply control valve 30, the operation control valve 101 and flow control valve 40 occurs, or cardiac massage (CPR) If the user stops the automatic breathing and by operating the manual control valve 70 to be manually switched may supply oxygen to a patient manually.

If it described in more detail, some of the oxygen supply to the pressure reducing valve 20 is a manual inlet valve case 71 via the second flow path (D2) connected to the second exhaust port 26. At this time, the user rotates while holding the trigger 74 of the manual control valve 70, as shown in Fig.

In accordance therewith, flows to the second flow (D2) to the input hole 75 is connected, as shown in Figure 16 the manual valve case 71 of claim 7 euros (D7) through the charged oxygen is open the output hole (76) in along the supply air directly to the air supply passage 60 is supplied to the patient.

Thereby, the ventilation apparatus according to the embodiment of the present invention can be used while the smooth supply of oxygen via a manual control valve 70 to the patient during the execution of an emergency or a cardiac massage in accordance with the failure of some components.

On the other hand, the above-described operation control unit may be provided with a pressure chamber 140, as shown in Fig. 4 and Fig. The pressure chamber 140 is a sealed housing having a filling space therein. These pressure chambers 140 are provided on the flow path connecting the bypass valve 100 and the operation control valve 101 causes pressurized oxygen to be supplied from the bypass valve 100 to the operation control valve 101.

The pressure chamber 140 is provided on the bypass line 106 to connect the by-pass valve 100 and the operation control valve 101 as shown in Figures 4 and 17. At this time, the pressure chamber 140 may be installed in the singular in the bypass flow path 106, as illustrated, but is composed of a plurality otherwise shown may be provided in sequence along the bypass line 106. The This pressure chamber 140 side is a bypass flow of oxygen through to the bypass valve 100 and the flow path and the other end is supplied through the by-pass valve 100 in accordance with the connected to the operating control valve 101 and the flow path ( along the 106) is filled therein.

In this way, the pressure chamber 140 when oxygen is supplied from the back to the bypass valve 100, after which the oxygen of the bypass valve 100 is charged, oxygen is newly supplied as the internal oxygen overcrowded already charged oxygen the presses. At this time, the pressure chamber 140, so naturally the internal pressure rises by the overcrowding of oxygen thereby discharging the oxygen which was first filled in the interior to the operating control valve 101. Then, the oxygen to be discharged from the pressure chamber 140 to the operating control valve 101 is also over the other pressure chamber 140, the pressure is maintained to increase by overcrowding is supplied to the hydraulic control valve 101. Therefore, the operation control valve 101 is that the cost of pressure, even if a small amount of oxygen is supplied by the pressure chamber 140 through the by-pass hole 105 of the bypass valve 100 doubles oxygen as shown in Figure 9 the spool 111 of the inside as shown in Fig. 13 and 14 as the supply thereby operating smoothly.

On the other hand, the air supply flow path 60 has the flow rate of oxygen supplied to the oxygen, i.e., a respiratory mask (13) is guided to the inside as shown in Figure 18 is controlled by a flow rate adjustment unit (FV). The flow rate adjustment unit (FV) is the time to discharge the oxygen that is supplied to the breathing mask (13) on the user's expiratory air supply flow path 60 to the outside stop the supply of oxygen, and the user of the intake air, as will be described later oxygen blocking the exhaust to be supplied again to the oxygen to a breathing mask (13). That is, the flow rate adjustment unit (FV) is expiratory, the user and to exhaust the breathing mask 13 to discharge the air to the outside stops the supply of oxygen, and re-breathing so that the air intake when a user to the intake of the oxygen back mask and supplying oxygen (13). Accordingly, the air supply flow path 60 has the flow rate of oxygen supplied to the breathing mask 13 is controlled through the flow rate adjustment unit (FV).

To do this, a flow rate adjustment unit (FV) is expiratory air supply flow path 60, a breathing mask 13 over the user's expiratory air supply flow path 60, the reason for exhausting oxygen is directed to a breathing mask 13 via the If oxygen is supplied to the carbon dioxide discharged from a human body exhaust valve (check valve) as a while does not exhaust the vortex supplied to the user of the intake air when again the user's breathing mask (13) by the pressure of the oxygen supplied to the breathing mask (13) since, it is provided to prevent this. Thus, the user can not re-intake of carbon dioxide during exhalation when provided with a flow rate varying unit (FV).

Flow rate adjustment unit (FV), for example, it can be configured to include a drain valve 160 and the switching valve 150, as illustrated in Fig. As the drain valve 160 is illustrated in FIGS. 18 and 19, having an air supply passage 60 and the drain hole (160a) in communication, by opening and closing a drain hole (160a) which is guided through the air supply passage (60) at least part of the oxygen evacuated or block the exhaust. The drain valve 160 through the first flow path 12 (D12), as illustrated, but can be in communication with the air supply flow path 60, and alternatively may be integrally attached to enable communication with the air supply passage (60). That is, the drain valve 160 is connected to the air supply passage (60) receiving the supply of oxygen from the air supply flow path 60 so that the exhaust through the drain hole (160a).

Drain valve 160 is, for example, can be configured to include a drain body 161, the opening and closing bundle 163 and the drain spring 165 as shown in Fig. The drain body (161) is the drain hole (160a) described above to one side is formed, and the other side is communicated with the air supply flow path 60 is in communication the oxygen of the air supply passage 60 through the other side as shown. That is, the drain body 161 exhausting the oxygen of the air supply passage 60, flowing through the other side via the drain hole (160a) of the one side. Drain body 161 may be formed in a variety of position drain holes (160a), preferably it formed on the side as illustrated.

Opening bundle 163 is built so as to be movable in the drain body 161 as shown in Fig. 18 and 19. Opening bundles 163 opens and closes the drain hole (160a) while moved by the oxygen of the switching valve 150 to be supplied to the drain body 161 as shown in FIGS. 19 to 21. Opening bundles 163 are preferably so as to open and close the drain hole (160a) formed on a side of the drain body (161), po pithyeong consists of the valve member as shown. Opening bundles 163 closes the drain hole (160a) of the drain body 161 while moving by the pressure of the oxygen flowing into the switching valve drain body 161 through 150, as shown in Fig. At this time, the drain body 161 oxygen is introduced through the first 11 euros (D11) connected to the oxygen supply hole (P2) of the switching valve 150.

Drain the spring 165 is compressed by the movement of the opening and closing bundle 163 as shown in Fig. And, the drain spring 165 is returned to if the oxygen supplied to the drain body 161 is blocked, the home position of opening bundles 163 as restore, as shown in Fig. Thus, the opening and closing bundles 163 opens the drain hole (160a) of the drain body (161).

Switching valve 150 operates the drain valve 160 to provide oxygen to the drain valve 160 is provided in the pressure-reducing valve (20). This switching valve 150, but may be supplying oxygen directly from a pressure reducing valve (20), than that receives supply of oxygen of the pressure reducing valve 20 through the above-described air supply control valve 30 as shown in FIG. 18 it is configured to provide a drain valve 160 is preferred. At this time, the air supply control valve 30 is a switching valve through the additional hole (35a) formed by adding oxygen to be supplied to the valve housing 31 from the pressure reducing valve 20 to the valve housing 31 as shown in FIG. 18 and supplies it to 150. Thus, the switching valve 150 may be linked to the air supply control valve 30 and drain valve 160.

Alternatively, the switch valve 150 may also be provided to the receiving oxygen of the reducing valve 20 through the above-mentioned manual control valve 70 supplies the drain valve 160 as shown in Fig. 22 and 23. Thus, the switch valve 150 may also be linked to the manual control valve 70 and drain valve 160.

Switching valve 150 is, for example, can comprise a needle housing 151, a needle 153 and a needle spring 155, as shown in Fig. 18 and 19. Provided by the needle housing 151 is the first 10 euros (D10) connected to the above-mentioned additional balls (35a) of the air supply control valve 30 is coupled, as illustrated by the air supply control valve 30 pressure reducing valve 20 oxygen inlet hole (P1) in which oxygen is introduced that is formed on one side. That is, the needle housing 151 is an oxygen flows through the oxygen inlet hole (P1) associated with the 10 euros (D10). Then, the needle housing 151 is such oxygen inlet hole (P1) and the oxygen-supplying hole for supplying, as shown by the arrows in Fig. 19 is communicated to the oxygen flowing into the oxygen inlet hole (P1) to the drain valve 160 ( P2) are provided on the other side. Thus, the needle housing 151 to thereby substantially oxygen of the pressure-sensitive valve 20 to a drain valve 160 to move the opening and closing bundles 163 of the drain valve 160.

Needle housing 151 has a charging hole (P3) which is the oxygen inlet of the pressure charging valve 20 to be supplied to the manual control valve 70 as illustrated in Figures 18 and 23 are formed. Then, the needle housing 151 is a guide hole (P4) which is guided a portion of the oxygen is supplied to bypass the charging hole (P3) as shown is formed. At this time, from the filling hole (P3) and the guide hole (P4) is a manual control valve 70, the air supply flow path described above for 60 supplies oxygen in the decompression valve 20 into the seventh flow path (D7) in as shown It is supplied with oxygen. For this purpose, the manual control valve (70) of claim 7 is branched from the flow path (D7) an eighth flow passage (D8), and the eighth flow path which is connected to the charging hole (P3) of the needle housing 151, as illustrated (D8) the branch is provided with a ninth yuro (D9) which is connected to the guide hole (P4) of the needle housing 151 from. Accordingly, the charging hole (P3) and the guide hole (P4) is supplied to the oxygen of the manual control valve 70 through an eighth yuro (D8) and ninth yuro (D9). However, the guide hole (P4) may be directly supplied oxygen from the seventh yuro (D7), unlike previously described.

Needle 153 opens and closes the oxygen inlet hole (P1) and the oxygen supply hole (P2) of as moving is built so as to be movable in needle housing 151, the needle housing 151, as shown in FIGS. 19 and 23 . Needle 153 is charged ball (P3) oxygen inlet hole (P1) and the oxygen supply while moving inside the needle housing 151 by the pressure of the oxygen flowing into the needle housing 151, as shown in Fig. 23 It opens and closes the hole (P2). At this time, the needle 153 opens and closes the oxygen inlet hole (P1) and the oxygen supply hole (P2) via the O-ring according to the O-ring is installed on the outer peripheral surface, as shown.

Needle 153 is secured in place in normal, the needle housing 151, as shown in FIG. 19 by communicating the oxygen inlet hole (P1) and the oxygen-supply hole (P2) is introduced into the oxygen inlet hole (P1) providing oxygen to the drain valve 160 through the oxygen supply hole (P2). Therefore, the drain valve 160 is a drain hole (160a) is closed since the opening bundle 163 by the oxygen that flows into the drain body (161) through the first 11 euros (D11) moves as illustrated.

Alternatively, the needle 153 is in the oxygen of the filling balls (P3) and the guide hole (P4) as if oxygen is flowing, the filling hole (P3) of the needle housing 151, as shown in Fig. 22 and 23 moved as shown by blocks, while the communication with the oxygen inlet hole (P1) and the oxygen-supply hole (P2) of the needle housing (151). At this time, the needle (153) to block the communication with the oxygen inlet hole (P1) and the oxygen-supply hole (P2), as located between the O-ring is an oxygen inlet hole (P1) and the oxygen-supply hole (P2), as shown. However, the needle 153 is guide hole (P4) and the oxygen-supply hole (P2) by communication with the guide hole (P4) oxygen supply ball oxygen flowing into of the needle housing 151, as shown by the arrow in FIG. 23 through (P2) provides a drain valve 160. Therefore, the drain valve 160 is the 11 euros (D11), because oxygen is supplied to the drain body 161 through the opening bundle 163 is moved close to the drain hole (160a), as shown.

Needle spring 155 is elastically supported by the needle 153 from the interior of the needle housing 151, as shown in FIGS. 19 and 23. In support of a needle spring 155 is charged ball (P3), if oxygen is not supplied, the needle 153 through the self-elasticity of the needle housing 151, as shown in FIGS. 19 and 21, needle 153 the movement will be prevented. And, a needle spring 155 is attached oxygen is supplied to the charging hole (P3) of the needle housing 151, as shown in Figure 23 is compressed when the needle 153 is moved, the filling hole of the needle housing 151 ( If the oxygen supply block P3) returns to its original position the needle 153 is restored again as a circle.

Flow rate adjustment unit (FV) having the above structure is the oxygen supply flow passage of the pressure-sensitive valve 20, the air supply control valve 30 as shown in FIG. 18 for the user of the intake air is opened through the flow control valve (40) If the supply (60), flows into the above-mentioned feed orifice 34 of oxygen, that is, the air supply control valve 30 is discharged at an additional ball (35a) flows into the air supply control valve 30, the discharge orifice 35 a portion of the oxygen is discharged to and flows into the switching valve 150 through the first 10 euros (D10). At this time, the switching valve 150 is introduced into the oxygen inlet hole (P1) and an oxygen inlet as the oxygen supply hole (P2) that the communication hole (P1) to the needle (153) is located in the home position as shown in FIG. 19 providing oxygen directly into the oxygen-supply hole (P2) to supply oxygen to the body-drain 161 of the drain valve 160 through the first 11 euros (D11). Accordingly, the drain valve 160 is opened and closed to shield bundle 163 is moved to the drain hole (160a) by the oxygen that flows into the drain body (161).

Due to this, the drain valve 160 may fail to discharge the oxygen supplied to the air supply passage 60 via the flow rate control valve 40 as described above. Accordingly, the air supply flow path 60 is supplied to the oxygen of the continuous flow rate control valve 40 to the breathing mask 13, the user of the air intake is possible.

However, the switching valve 150 is an air supply flow path 60, the discharge orifice 35 of the air supply control valve 30 is shielded with an additional hole (35a) through the flow control valve 40, as shown in Figure 20 If the oxygen is not being supplied, the oxygen inlet hole (P1) with even does not supply oxygen to the body-drain 161 of the drain valve 160 as shown in Figure 21 is not oxygen is supplied. Therefore, the drain valve 160 opens the drain hole (160a) formed in the drain body (161) while opening bundle 163 returns to the original position by the spring drain 165.

At this time, the operation control valve 101, as shown in the attached oxygen, that is, oxygen-20 was pressed the spool 111 is filled therein as shown in Fig. 14 filled therein, as shown in Figure 20 through the bypass flow path 106 after the inlet to the bypass valve 100 is supplied to the air supply passage 60 by the flow control valve 40 is slowly evacuated through the air supply passage (60). Drain body 161 so the drain holes as the oxygen of the air supply operation that is discharged through the flow passage 60, the control valve 101 shown in Figure 21 as the open drain hole (160a) as described above (160a) and through the exhaust. Of course, the drain hole (160a) is exhausting the oxygen of a twelfth air supply passage 60 as oxygen is introduced into the drain body 161 of the air supply flow path 60 via a flow path (D12) as shown in Figure 20 . Accordingly, the air supply flow path 60 does not provide any oxygen to the breathing mask (13). Due to this, the user can voluntary and respiratory expiratory carbon dioxide in respiratory mask 13 according to the intake air after exhalation as not oxygen is supplied to the breathing mask 13, the eddy current is prevented by the interference of the oxygen as discussed above no intake of carbon dioxide again.

On the other hand, the seventh yuro as shown in Figure 22. As the manual control valve (70) the air supply control valve 30 is operated as previously described for the respiration of the US when starting up, the user (patient) by a failure ( through D7) and supplies the oxygen of the reducing valve 20 to the air supply passage (60). At this time, the switching valve 150, the oxygen is introduced into the filling hole (P3) of the seventh yuro the needle housing 151 with eight euros (D8) which is branched from (D7) as shown in Fig. 22 and 23 do. Furthermore, the switching valve 150 is the oxygen of the guide hole (P4) into the seventh yuro (D7) via a ninth yuro branched in claim 8 euros (D8), (D9) is introduced.

Switching valve 150 is charged ball (P3) the needle 153 is moved while the oxygen inlet hole (P1) and an oxygen supply ball built into the needle housing 151 by the oxygen flowing into, as shown in Figure 23 ( blocks the communication of P2). At the same time, the switching valve 150 through the guide hole (P4) and the oxygen-supply hole (P2) by communication with the guide hole (P4) oxygen supply hole (P2) of oxygen flowing into as illustrated drain valve (160 ) it is fed to. At this time, the drain valve 160 is opened and closed as bundles 163 is moved back, as illustrated as the oxygen is introduced through the first 11 euros (D11) to close the drain hole (106a). Accordingly, the air supply flow path 60 is smoothly supplying oxygen to the breathing mask 13, the oxygen flowing through the inside is not exhausted to the drain valve 160. Due to this, the breathing mask 13 can continuously supply oxygen to the user the required intake.

Consequently, the flow rate operation as described above varying unit (FV) is 18 and 22 for the user of the intake air, as shown in by the operation of the air supply control valve 30, or the oxygen is supplied to the air supply passage (60) and closing the air supply flow path when the 60 where oxygen is supplied, a drain hole (160a) of the drain valve 160 so that the oxygen is smoothly supplied to the breathing mask (13) by a manual control valve (70). Then, the flow rate adjustment unit (FV) is open to the drain hole (160a) of the drain valve 160 as shown in Figure 20 so as not oxygen is supplied to the breathing mask 13 when the user's breath to the air supply passage (60) and exhausting the oxygen flowing through to the outside.
