Description

  The present invention relates to a breathing-tuned flow regulator integrated valve used by being connected to a gas supply source such as an oxygen cylinder in home oxygen therapy or respiratory assistance for a patient with chronic respiratory failure or the like.

  Conventionally, as a flow regulator connected to an oxygen cylinder or the like in home oxygen therapy or the like, a continuous supply type that continuously supplies a gas at a predetermined flow rate such as oxygen and a gas at a predetermined flow rate that is breathed by a user There is a breath-synchronization system that supplies in synchronization with the. Among these, the breath synchronization type is configured to detect the negative pressure when the user inhales (when inhaling) and supply gas only when the user inhales. Compared with the continuous supply type As a result, the duration of oxygen cylinders and the like is longer.

  In other words, according to the breathing-tuned flow regulator, it is possible to extend the duration of the user by extending the duration of the oxygen cylinder, etc., or to increase the portability by reducing the capacity of the oxygen cylinder, etc. Therefore, it is attracting attention as contributing to the improvement of QOL (Quality Of Life) of users.

  As such a breath-tuned flow rate regulator, one having a structure of connecting to a post valve attached to an oxygen cylinder or the like via a yoke has been generally used (see, for example, Patent Document 1). However, the structure connected to the post valve via the yoke has a problem that not only it takes time to attach and detach, but also a connection error tends to occur. In particular, since a user who needs respiratory assistance is often an elderly person, a structure that is easy to handle has been desired.

  In response to such a demand, in recent years, a breath-synchronized flow regulator is integrated with a valve, and a breathing-synchronized flow regulator integrated type is provided with a filling port for filling an oxygen cylinder or the like with oxygen. A valve or the like has also been proposed (see, for example, Patent Document 2). By integrating the breath tuned flow controller with the valve and filling port in this way, once connected to an oxygen cylinder, etc., it is continuously continued without attaching or detaching equipment except during inspection and maintenance. Can be used. Therefore, such an integrated device can be handled relatively easily even by an elderly person.

  However, in the breath synchronization type flow regulator integrated valve shown in Patent Document 2, a compact configuration is realized by disposing the flow rate adjustment section between the pressure adjustment section and the breath synchronization section. There is a problem that it is difficult to adjust the flow rate, and the benefits of breathing synchronization may be halved. That is, since the supply gas is adjusted by the flow rate adjustment unit and then passes through the breathing synchronization unit, the gas after the flow rate adjustment is easily affected by the operation of the breathing synchronization unit, and the accurate flow rate adjustment is performed.

That is, the gas pressure after the pressure adjustment is reduced as the residual pressure is reduced due to the consumption of gas, so that there is a problem that the accuracy of the flow rate adjustment is lowered and the merit of breathing synchronization is also halved.

  In view of such circumstances, the present invention is intended to provide a breathing-tuned flow regulator integrated valve that is compact and easy to use while allowing high-accuracy flow adjustment.

Yes.

  As shown in FIGS. 1 to 4, the integrated valve 1 includes a main body 10 configured in a substantially cross shape, a connection portion 20 connected to the gas supply source 2, and gas to the connected gas supply source 2. A filling port 30 for filling, a pressure gauge 40 that measures and displays the pressure of the gas supply source 2, a first pressure adjusting unit 50 that depressurizes the gas flowing in from the gas supply source 2, and a first pressure A second pressure adjusting unit 60 that depressurizes the gas flowing in from the adjusting unit 50; a respiratory tuning unit 70 that discharges the gas flowing in from the second pressure adjusting unit 60 in synchronization with the breathing of the user; and a respiratory tuning unit A flow rate adjusting unit 80 for adjusting the flow rate of the gas flowing in from 70 or the gas flowing in from the second pressure adjusting unit 60; a nozzle 90 for discharging gas from the flow rate adjusting unit 80; and an extension attached to the main body 10. Member 100.

  The main body 10 includes a first protrusion 11 protruding in the x negative direction, a second protrusion 12 protruding in the x positive direction, a third protrusion 13 protruding in the z negative direction, and a z positive direction. It has a substantially cross shape having a projecting fourth projecting portion 14. Among these, the first protrusion 11 is provided with a filling port 30, and the second protrusion 12 is provided with a first pressure adjusting part 50. Further, the main body 10 is connected to the gas supply source 2 via a connection portion 20 provided in the third protrusion 13. The fourth protrusion 14 is provided with a second pressure adjustment unit 60, and the breathing synchronization unit 70 and the flow rate adjustment are connected to the main body 10 via the extending member 100 attached to the fourth protrusion 14. The part 80 is fixed. That is, the fourth projecting portion 14 functions as an extending projecting portion.

  The connection part 20 is provided in the 3rd protrusion part 13 of the main body 10 as mentioned above. A male screw 21 having a predetermined standard is formed on the outer peripheral portion of the connecting portion 20. That is, the connecting portion 20 is configured to be connected to the gas supply source 2 by screwing the male screw 21 into a female screw 2 b formed on the base 2 a of the gas supply source 2. Further, from the front end 22 of the connecting portion 20 to the inside of the main body 10, the gas is supplied into the gas supply source 2 from the supply passage 15 that leads the gas in the gas supply source 2 to the first pressure adjusting portion 50 and the filling port 30. A filling passage 16 is formed.

  In addition, the connection part 20 is not limited to what has the male screw 21, What is necessary is just to have a structure according to the specification of the connection end of the gas supply source 2 connected. That is, the connection part 20 may have a female screw, for example, and may be provided with an appropriate clamp structure.

  The filling port 30 is a portion to which a connection end of a supply source that supplies a filling gas is connected when the gas supply source 2 is filled with gas. The filling port 30 is provided in the first projecting portion 11 of the main body 10, and includes a connection port 31 that communicates with the outside and a check valve unit 32 that opens and closes the connection port 31 according to a pressure difference between the inside and the outside. ing. The check valve unit 32 includes a substantially cylindrical sleeve 32a, a valve body 32b that is reciprocally movable in the sleeve 32a in the axial direction, and a spring 32c that biases the valve body 32b toward the connection port 31. And. That is, the check valve unit 32 normally closes the connection port 31 with the valve body 32b by the urging force of the spring 32c, and when filling the gas, the connection port 31 is opened by pressing the valve body 32b with the filling pressure. It is comprised so that. The opened connection port 31 is connected to the filling passage 16 through a passage (not shown), and the filling gas passes through the filling passage 16 and flows into the gas supply source 2.

  A male screw 33 of a predetermined standard is formed on the outer peripheral portion of the filling port 30, and the connection end of the supply source of the filling gas is connected to the filling port 30 by being screwed into the male screw 33. The filling port 30 is usually provided with a cap 34, and the connection port 31 and the male screw 33 are protected by the cap 34. In addition, the filling port 30 is not limited to the one having the male screw 33 like the connection portion 20, and may include, for example, a one-touch coupler. The check valve unit 32 may have other known structures.

  In this embodiment, by providing the filling port 30 in the first projecting portion 11, it is possible to provide the filling passage 16 for filling separately from the main supply passage 15. That is, the space for forming the filling passage 16 is ensured by arranging the filling port 30 so as to be offset in the x negative direction with respect to the connecting portion 20.

  Thus, by providing the filling passage 16 separately from the supply passage 15, it is possible to prevent the pressure during filling from being directly applied to the first pressure adjustment unit 50 and the second pressure adjustment unit 60. . In other words, when the gas is filled, an excessive pressure may act shockfully at the start of filling, but the first pressure adjusting unit 50 and the second pressure can be passed through the gas supply source 2 from the filling passage 16. It is possible to reduce the pressure applied to the pressure adjusting unit 60. Thereby, in this embodiment, since it is possible to prevent inadvertent wear, deformation or breakage of the first pressure adjustment unit 50 and the second pressure adjustment unit 60, highly accurate flow rate adjustment can be performed for a long time. It is possible to maintain.

  In this embodiment, the filling port 30 protrudes from the main body 10 and the connection direction of the connection end of the supply source of the filling gas is aligned with the protruding direction (that is, the x negative direction), thereby enabling easy connection. It is said. Further, the first projecting portion 11 is formed in a substantially rod shape by aligning the moving direction of the valve body 32b of the check valve unit 32 with the projecting direction of the filling port 30 (that is, the x negative direction). The shape of the main body 10 is realized.

  The pressure gauge 40 is fixed to the y negative direction side of the substantially central portion of the main body 10. The pressure gauge 40 is connected to the supply passage 15, measures the pressure in the supply passage 15, that is, the pressure in the gas supply source 2, and displays the measured pressure value on the display unit 40 a. In addition, since the internal structure of the pressure gauge 40 is a known general structure, detailed description is abbreviate | omitted here.

  The display unit 40a of the pressure gauge 40 includes a pointer 41 and a display dial 42 arranged behind the pointer 41 (y positive direction side), and is provided in a state protruding from the main body 10 in the y negative direction. The pointer 41 of the display unit 40a is disposed so as to rotate about the y-axis, and the tip end portion 41a is bent in the positive y direction. The display dial 42 behind the pointer 41 is formed in a substantially cylindrical shape with the y-axis as the center, and both the y negative direction side end surface 42a and the z positive direction side outer peripheral surface 42b are graduated. Yes.

  That is, the pressure gauge 40 of the present embodiment is configured so that the pressure value can be confirmed from either the front or the upper side, and without greatly changing the posture of the gas supply source 2 and the integrated valve 1, The residual pressure in the gas supply source 2 can be confirmed very easily. Moreover, in this embodiment, the visibility of the display part 40a is made by projecting the display part 40a of the pressure gauge 40 in the y negative direction orthogonal to any of the projecting directions of the first to fourth projecting parts 11-14. Is prevented from being inhibited by other parts of the integrated valve 1.

  The first pressure adjustment unit 50 reduces the gas pressure of the gas supply source 2 and transmits it to the second pressure adjustment unit 60. Specifically, the gas pressure (source pressure) in the gas supply source 2 such as an oxygen cylinder decreases according to gas consumption, and generally decreases from a maximum of 20 MPa to 1 MPa or less in some cases. The pressure adjusting unit 50 of 1 reduces the gas pressure varying in this way to 0.5 ± 0.05 MPa. Therefore, the gas flows into the second pressure adjusting unit 60 at a gas pressure of 0.45 to 0.55 MPa in which the fluctuation range is suppressed together with the pressure reduction.

  FIG. 5 is an enlarged cross-sectional view showing the vicinity of the first pressure adjusting unit 50 and the second pressure adjusting unit 60. The first pressure adjusting unit 50 is provided in the second projecting portion 12 of the main body 10, and has a substantially cylindrical housing 51 that is open at one end in the axial direction and closed at the other end. A piston 52 that is reciprocally movable in the axial direction, a piston presser 53 that closes the open end 51 a of the housing 51, and a spring 54 that biases the piston 52 toward the piston presser 53 are provided.

  The housing 51 is accommodated in the second projecting portion 12 with the open end 51a facing outward (x positive direction side), and is fixed by being pressed from the outside together with the piston retainer 53 by the fixed plug 50a. . An inflow passage 51c connected to the supply passage 15 is provided at the closed end 51b at the other end (x negative direction side) of the housing 51, and gas from the supply passage 15 passes through the inflow passage 51c to form a piston. 52 and the inflow chamber 55 between the closed end 51b. Note that a filter 50b is disposed between the supply passage 15 and the inflow passage 51c to prevent entry of dust or the like into the first pressure adjustment unit 50.

  The piston 52 has a substantially stepped shaft shape including a large diameter portion 52a on the opening end 51a side (piston presser 53 side) of the housing 51 and a small diameter portion 52b on the closing end 51b side. An adjustment chamber 56 is formed between the large-diameter portion 52a of the piston 52 and the piston retainer 53, and this adjustment chamber 56 communicates with the inflow chamber 55 via a communication passage 52c formed inside the piston 52. Yes. That is, the piston 52 resists the urging force of the spring 54 when the pressure of the gas flowing into the inflow chamber 55 and the adjustment chamber 56 is high due to the difference in diameter between the large diameter portion 52a and the small diameter portion 52b. By moving toward the closed end 51b side of the housing 51, and thereby closing the inflow passage 51c (opening is reduced), the pressure in the inflow chamber 55 and the adjustment chamber 56 is reduced. It has become.

  A valve seat 57 that enhances the adhesion with the peripheral edge of the inflow passage 51c is disposed at the tip of the small diameter portion 52b of the piston 52. The spring 54 is disposed between the end surface of the large-diameter portion 52a of the piston 52 on the small-diameter portion 52b side and a substantially ring-shaped receiving seat 58 into which the small-diameter portion 52b is inserted.

  The receiving seat 58 is pressed against the stepped portion of the housing 51 by the urging force of the spring 54, so that the intermediate chamber 59 between the receiving seat 58 and the large diameter portion 52 a of the piston 52 is moved from the inflow chamber 55 and the adjustment chamber 56. It functions to shut off. Similarly to the piston 52, the seat 58 is disposed so as to be able to reciprocate in the housing 51 in the axial direction, and the intermediate chamber 59 is opened to the atmosphere by a relief passage 51d. That is, the seat 58 moves against the biasing force of the spring 54 when an abnormal high pressure is applied to the inflow chamber 55 and the adjustment chamber 56, and the inflow chamber 55 and the adjustment chamber 56 communicate with the intermediate chamber 59. It also functions as a relief valve that allows the pressure to escape.

  The gas decompressed by the first pressure adjustment unit 50 is guided to the second pressure adjustment unit 60 through the discharge passage 51e formed in the housing 51 and the connection passage 17 formed in the main body 10. The second pressure adjusting unit 60 reduces the gas flowing in at a gas pressure of 0.45 to 0.55 MPa to 0.14 MPa.

  The second pressure adjustment unit 60 is provided in the fourth protrusion 14 of the main body 10 and has basically the same structure and function as the first pressure adjustment unit 50. That is, the second pressure adjusting unit 60 includes a substantially cylindrical housing 61 that is open at one end in the axial direction and closed at the other end, and a piston 62 that is disposed so as to be capable of reciprocating in the housing 61 in the axial direction. A piston retainer 63 that closes the open end 61 a of the housing 61 and a spring 64 that biases the piston 62 toward the piston retainer 63 are provided.

  The housing 61 is accommodated in the fourth projecting portion 14 with the opening end 61a facing outward (z positive direction side), and is fixed by being pressed from the outside together with the piston presser 63 by the fixed plug 60a. . An inflow passage 61c connected to the connection passage 17 is provided at the closed end 61b at the other end (z negative direction side) of the housing 61, and gas from the connection passage 17 passes through the inflow passage 61c to form a piston. It flows into the inflow chamber 65 between 62 and the closed end 61b.

  The piston 62 has a substantially stepped shaft shape including a large diameter portion 62a on the opening end 61a side (piston presser 63 side) of the housing 61 and a small diameter portion 62b on the closed end 61b side. An adjustment chamber 66 is formed between the large-diameter portion 62a of the piston 62 and the piston retainer 63. The adjustment chamber 66 communicates with the inflow chamber 65 via a communication passage 62c formed in the piston 62. Yes. A valve seat 67 is disposed at the tip of the small diameter portion 62b of the piston 62 to enhance the adhesion with the peripheral edge of the inflow passage 61c. The spring 64 is disposed between the end surface of the large-diameter portion 62a of the piston 62 on the small-diameter portion 62b side and the substantially ring-shaped receiving seat 68 into which the small-diameter portion 62b is inserted.

  The receiving seat 68 is pressed against the stepped portion of the housing 61 by the biasing force of the spring 64, so that the intermediate chamber 69 between the receiving seat 68 and the large-diameter portion 62 a of the piston 62 is moved from the inflow chamber 65 and the adjustment chamber 66. It functions to shut off. Further, the receiving seat 68 is disposed so as to be reciprocally movable in the housing 61 in the axial direction, and the intermediate chamber 69 is opened to the atmosphere by the relief passage 18. That is, the seat 68 functions also as a relief valve.

  The gas decompressed by the second pressure adjusting unit 60 passes through the discharge passage 63a formed in the piston presser 63 and the discharge passage 60b formed in the fixed plug 60a, and is in breathing synchronization with the second pressure adjusting unit 60. Guided to a buffer chamber 19 (see FIG. 4) provided between the sections 70.

  In the present embodiment, the gas pressure supplied to the breathing synchronization unit 70 and the flow rate adjustment unit 80 is reduced by reducing the pressure in two stages by the two pressure adjustment units of the first pressure adjustment unit 50 and the second pressure adjustment unit 60. It is made difficult to be affected by a change in pressure in the gas supply source 2. That is, the required pressure reducing capacity is distributed to the first and second pressure adjusting units 50 and 60 to increase the accuracy of the pressure adjustment, and about 0.1 MPa generated by the change (decrease) in the pressure in the gas supply source 2. The change in the discharge pressure of the first pressure adjusting unit 50 can be absorbed by the second pressure adjusting unit 60. As a result, the gas pressure supplied to the breathing synchronization unit 70 and the flow rate adjusting unit 80 can be substantially constant at 0.14 MPa, and as a result, highly accurate flow rate adjustment is possible.

  Further, in the present embodiment, the arrangement of the first and second pressure adjusting units 50 and 60 is devised to make the main body 10 compact and efficient while enabling highly accurate pressure adjustment and flow rate adjustment. It is possible to do. Specifically, the supply passage 15 and the filling passage 16 can be arranged without difficulty by disposing the first pressure adjusting unit 50 offset in the positive x direction with respect to the connection unit 20. In addition, by aligning the moving direction of the piston 52 of the first pressure adjusting unit 50 with the protruding direction of the second protruding portion 12 (that is, the x positive direction), the first protruding portion 11 has a substantially rod-shaped compact shape. It is possible to configure.

  Thus, the 1st and 2nd protrusion parts 11 and 12 are made into the integral valve | bulb 1 and the gas supply source 2 by comprising the 2nd protrusion part 12 in a substantially rod shape with the above-mentioned 1st protrusion part 11. FIG. Can be used effectively as a handle. FIG. 6 is a view showing an example of a usage state when the first and second protrusions 11 and 12 are used as handles. As shown in the figure, in the present embodiment, the integrated valve 1 and the gas supply source 2 can be made very easy by, for example, placing the index finger and the middle finger on the first and second protrusions 11 and 12 from below. It is possible to lift it up.

  In particular, in the present embodiment, since no protruding portion is provided on the y-positive direction side of the integral valve 1, the first and second palms are arranged in a state where the palm is along the surface of the integral valve 1 on the y-positive direction side. It is possible to lift the integrated valve 1 and the gas supply source 2 very stably by placing a finger on the second protrusions 11 and 12. In addition, by preparing the first and second protrusions 11 and 12 that can ensure sufficient strength as handles, the pressure gauge 40, the flow rate adjusting unit 80, the nozzle 90, etc. Since it is possible to reduce the possibility that the integral valve 1 and the gas supply source 2 can be lifted with a portion that is difficult to ensure, it is possible to effectively prevent inadvertent failures and breakage.

  In the present embodiment, as shown in FIGS. 1 to 4, the second pressure adjustment unit 60 is arranged offset in the z positive direction with respect to the filling port 30 and the first pressure adjustment unit 50, and By aligning the moving direction of the piston 62 of the second pressure adjusting unit 60 with the protruding direction of the fourth protruding portion 14 (ie, the positive z direction), the respiratory tuning unit 70 and the flow rate adjusting unit 80 can be arranged efficiently. It is possible. Specifically, by disposing the second pressure adjusting unit 60 in this way, the breathing synchronization unit 70 and the flow rate are passed through the substantially cylindrical extending member 100 that fits outside the fourth protrusion 14. The adjustment unit 80 can be attached to the main body 10. Accordingly, the breath synchronization unit 70 and the flow rate adjustment unit 80 can be easily attached and detached and securely fixed to the main body 10 while arranging the breath synchronization unit 70 and the flow rate adjustment unit 80 at optimal positions. Yes.

  The extending member 100 is configured in a substantially cylindrical shape as described above, and the fourth protruding portion 14 of the main body 10 is inserted into one end side (z negative direction side) in the axial direction. It can be attached to the main body 10. In this embodiment, the extending member 100 is fixed to the main body 10 by a plurality of set screws 100a. However, the extending member 100 is fixed to the main body by other known methods such as appropriate engagement and clamping. 10 may be fixed.

  The breath synchronization unit 70 discharges the gas flowing from the buffer chamber 19 toward the flow rate adjustment unit 80 after synchronizing with the breathing of the user. The breathing synchronization unit 70 is configured in a columnar shape with a flange by combining a plurality of members, and the columnar portion 70a is inserted into the other end side (the z positive direction side) of the extending member 100, and the flange portion 70b. Is fixed to the extending member 100 by fastening with a plurality of bolts 70c. The buffer chamber 19 into which the gas decompressed by the second pressure adjusting unit 60 flows is configured by a space between the fourth projecting portion 14 and the cylindrical portion 70a. In the present embodiment, such a configuration ensures a sufficient volume of the buffer chamber 19 so that gas is stably supplied to the breathing synchronization unit 70 and the flow rate adjustment unit 80.

  FIG. 7 is an enlarged cross-sectional view showing the periphery of the breathing synchronization unit 70. The breath synchronization unit 70 includes a supply gas chamber 71 into which a gas to be supplied to the user flows, a supply gas inflow passage 72 that connects the buffer chamber 19 and the supply gas chamber 71, and a first that opens and closes the supply gas inflow passage 72. In the control gas chamber 74, a control gas chamber 74 into which a control gas for controlling opening and closing of the first diaphragm valve 73 flows, a control gas inflow passage 75 that communicates the buffer chamber 19 and the control gas chamber 74, A control gas discharge chamber 76 that communicates with the outside for discharging the gas, a control gas discharge passage 77 that communicates the control gas chamber 74 and the control gas discharge chamber 76, and a second that opens and closes the control gas discharge passage 77. A diaphragm valve 78 and a pressure detection chamber 79 that controls opening and closing of the second diaphragm valve 78 in accordance with the pressure in the vicinity of the nozzle 90 are provided.

  The supply gas chamber 71 includes a discharge passage 70d formed in the cylindrical portion 70a, a tuning clearance passage 101 formed between the cylindrical portion 70a and the extending member 100, and a tuning connection formed in the extending member 100. The flow rate adjustment unit 80 is connected via the passage 102. That is, the gas synchronized with the user's breathing flows from the supply gas chamber 71 through the discharge passage 70d, the tuning gap passage 101, and the tuning connection passage 102 into the flow rate adjusting unit 80. .

  In the present embodiment, two O-rings 110 are arranged on the outer periphery of the columnar portion 70a of the breathing synchronization unit 70, and a gap between the breathing synchronization unit 70 and the extending member 100 between the two O-rings 110 is provided. The tuning clearance passage 101 is used. That is, in this embodiment, the processing cost of a member is reduced by utilizing effectively the clearance gap between the respiration synchronization part 70 and the extending member 100 as a channel | path along the circumferential direction.

  The supply gas chamber 71 and the control gas chamber 74 are partitioned by a first diaphragm valve 73. The first diaphragm valve 73 is urged toward the supply gas inflow passage 72 by a spring 73a disposed in the control gas chamber 74, so that the supply gas inflow passage 72 is normally connected to the supply gas chamber. It is blocked from the 71 side.

  That is, when the pressure in the buffer chamber 19 and the supply gas inflow passage 72 and the pressure in the control gas chamber 74 are balanced, the first diaphragm valve 73 is supplied with the supply gas inflow passage 72 by the biasing force of the spring 73a. Is supposed to block. In addition, when the gas in the control gas chamber 74 is discharged to the outside through the control gas discharge passage 77 and the control gas discharge chamber 76 and the pressure in the control gas chamber 74 decreases, the buffer chamber 19 and the supply gas inflow passage 72 are supplied. The first diaphragm valve 73 is separated from the supply gas inflow passage 72 by the internal pressure, and the supply gas inflow passage 72 is opened.

  The control gas discharge chamber 76 and the pressure detection chamber 79 are partitioned by a second diaphragm valve 78. The second diaphragm valve 78 is urged toward the control gas discharge passage 77 by a spring 78a disposed in the pressure detection chamber 79, so that the control gas discharge passage 77 normally discharges the control gas. It is closed from the chamber 76 side. The control gas discharge chamber 76 communicates with the outside through a passage (not shown), and the inside of the control gas discharge chamber 76 is maintained at substantially atmospheric pressure. The pressure detection chamber 79 communicates with a final discharge passage 103 formed in the extending member 100 via a pressure detection passage 79 a formed across the pressure adjusting unit 70 and the extending member 100.

  The final discharge passage 103 is a passage connected to the nozzle 90, and is a passage through which the gas discharged from the flow rate adjusting unit 80 passes. Further, a tube connected to a cannula generally inserted into the user's nasal cavity is connected to the nozzle 90. Accordingly, the negative pressure at the time of inhalation by the user is transmitted to the final discharge passage 103 via the cannula, tube and nozzle 90, and further to the pressure detection chamber 79 via the pressure detection passage 79a.

  That is, the second diaphragm valve 78 is configured such that when the user exhales (when exhaling), the pressure in the control gas discharge chamber 76 and the pressure detection chamber 79 are both balanced at substantially atmospheric pressure. The control gas discharge passage 77 is closed by the biasing force of the spring 78a. Further, when the user inhales, the pressure detection chamber 79 has a negative pressure (below atmospheric pressure), so the second diaphragm is controlled by the pressure in the control gas discharge chamber 76, the control gas discharge passage 77 and the control gas chamber 74. The valve 78 is separated from the control gas discharge passage 77, and the control gas discharge passage 77 is opened.

  With this configuration, the breathing synchronization unit 70 can supply gas toward the flow rate adjustment unit 80 only when the user inhales. That is, when the pressure in the pressure detection chamber 79 becomes negative (below atmospheric pressure) due to the user's inspiration, first, the second diaphragm valve 78 opens the control gas discharge passage 77. As a result, the control gas in the control gas chamber 74 flows out, and the first diaphragm valve 73 opens the supply gas inflow passage 72. When the supply gas inflow passage 72 is opened, the gas in the buffer chamber 19 flows into the supply gas chamber 71 and further passes through the discharge passage 70d, the tuning gap passage 101, and the tuning connection passage 102 to adjust the flow rate. Flows into the section 80.

  The gas flowing into the flow rate adjusting unit 80 is supplied to the user through the final discharge passage 103 and the nozzle 90 after the flow rate is adjusted (details will be described later). At this time, since the pressure in the pressure detection chamber 79 is increased by the gas passing through the final discharge passage 103, the second diaphragm valve 78 closes the control gas discharge passage 77. Then, the discharge of the control gas from the control gas chamber 74 to the outside stops and the pressure in the control gas chamber 74 rises, so that the first diaphragm valve 73 closes the supply gas inflow passage 72. Thereby, the inflow of the gas to the flow rate adjusting unit 80 is stopped, and as a result, the supply of the gas to the user is stopped.

  In the present embodiment, the pressure detection passage 79a is connected to the final discharge passage 103 on the upstream side of the nozzle 90, so that the pressure rise is detected relatively quickly compared to the so-called double lumen type described in Patent Document 1. The second diaphragm valve 78 closes the control gas discharge passage 77 at a relatively early timing. The timing at which the first diaphragm valve 73 closes the supply gas inflow passage 72 after the control gas discharge passage 77 is closed is adjusted by a needle valve 75 a provided in the middle of the control gas inflow passage 75.

  By doing in this way, the timing which stops supply of gas can be set suitably. For example, in the case of human breathing, in consideration of the fact that only the gas sucked into the first half of inspiration reaches the lungs, the flow rate of the control gas from the buffer chamber 19 to the control gas chamber 74 is increased. By setting the gas supply stop timing to a relatively early timing, it becomes possible to save gas without impairing the effect of breathing assistance. However, if the control gas inflow rate is increased, the control gas discharge rate when the control gas discharge passage 77 is opened (that is, when the gas is supplied) increases. Subtle adjustment is required in consideration of the balance between the gas supply stop timing and the amount of control gas discharged during gas supply. In the present embodiment, by providing the needle valve 75a, it is possible to finely adjust the inflow speed of the control gas, and as a result, it is possible to set the gas supply stop timing to a timing that saves gas to the maximum. It has become.

  The flow rate adjusting unit 80 discharges the gas flowing in from the breath synchronization unit 70 or the gas flowing in from the buffer chamber 19 toward the nozzle 90 after adjusting the flow rate. As shown in FIGS. 1 to 4, the flow rate adjustment unit 80 is fixed to the x positive direction side of the extending member 100 in a state of straddling the second pressure adjustment unit 60 and the breathing synchronization unit 70. Yes.

  FIG. 8 is an enlarged cross-sectional view showing the periphery of the flow rate adjusting unit 80. The flow rate adjusting unit 80 is fixed to the extending member 100 by a substantially disc-shaped flow rate adjusting plate 81, a rotary shaft 82 connected to the central portion of one end side (x-positive direction side) of the flow rate adjusting plate 81, and a bolt 80a. The support member 83 that rotatably supports the rotating shaft 82, the operation dial 84 that is connected to the opposite side (x positive direction side) of the rotating shaft 82 to the flow rate adjusting plate 81, and the support member 83. And a cover 85 that covers a part of the operation dial 84 on the rotating shaft 82 side (x negative direction side) from the outer peripheral side.

  The flow rate adjusting plate 81 is disposed such that the other end side (x negative direction side) faces the facing surface 104 formed on the extending member 100 on the x positive direction side. The tuning connection passage 102 through which the gas from the breathing synchronization unit 70 toward the flow rate adjustment unit 80 passes is formed so as to communicate with the facing surface 104. The extension member 100 is also formed with a continuous connection passage 105 that directly communicates the buffer chamber 19 with the facing surface 104. When continuously supplying gas to the user, this continuous passage is provided. The gas in the buffer chamber 19 passes through 105 and flows directly into the flow rate adjusting unit 80. 4, 7, and 8, the cross-sectional position of the continuous connection passage 105 is shifted in order to facilitate understanding.

  A plurality of tuning orifices 81a and continuous orifices 81b, which are orifices penetrating in the thickness direction, are formed in the flow rate adjusting plate 81, respectively. Among these, the tuning orifice 81a is provided at a position corresponding to the position of the tuning connection passage 102 on the facing surface 104, and a plurality of tuning orifices 81a having different hole diameters are arranged at equal intervals along the circumferential direction. Has been. The continuous orifices 81b are provided at positions corresponding to the positions of the continuous connection passages 105 on the facing surface 104, and a plurality of continuous orifices 81b having different hole diameters are arranged at equal intervals along the circumferential direction. ing.

  That is, the flow rate adjusting unit 80 operates the operation dial 84 to rotate the flow rate adjusting plate 80, and adjusts the tuning mode (respiratory mode of the user depending on which hole diameter tuning orifice 81 a communicates with the tuning connection passage 102. The gas supply flow rate is set in a plurality of stages, and the continuous orifice 81b of which hole diameter is made to communicate with the continuous connection passage 105, the continuous mode (the gas is continuously supplied). The gas supply flow rate in the supply mode) is set to a plurality of stages. The rotational position of the flow rate adjusting plate 81 is determined by engaging positioning balls 86 arranged on the support member 83 with a plurality of positioning recesses 84 a provided on the operation dial 84. The positioning ball 86 is housed in a housing recess 83a provided on the surface of the support member 83 that faces the operation dial 84, and is biased toward the operation dial 84 by a spring 87 disposed in the housing recess 83a. Has been.

  Further, when any of the tuning orifices 81a communicates with the tuning connection passage 102, the flow rate adjusting plate 81 closes the continuous connection passage 105, and any of the continuous orifices 81b is connected to the continuous connection passage. When communicating with 105, the tuning connecting passage 102 is configured to be closed. Further, the flow rate adjusting plate 81 is configured to close the tuning connection passage 102 and the continuous connection passage 105 in the reference rotation position, that is, to be in a closed mode in which the integrated valve 1 is closed.

  Therefore, the flow rate adjusting unit 80 is configured to be able to switch between the closed mode, the tuning mode, and the continuous mode only by operating (rotating) the operation dial 84, and to adjust the flow rate in the tuning mode and the continuous mode as it is. Further, the flow rate adjusting unit 80 functions as a source valve that opens and closes the gas supply source 2. 1-4 and 8 show the case where the flow rate adjusting plate 81 is set to the reference rotation position. In this embodiment, the operation dial 84 is rotated clockwise from FIG. When the mode is switched to the tuning mode (the original valve is opened), the flow rate setting in the tuning mode is increased. Then, when the operation dial 84 is rotated about 180 ° from the reference rotation position, the tuning mode is switched to the continuous mode, and further the clockwise rotation is performed to increase the flow rate setting in the continuous mode. .

  Further, on the outer peripheral surface 84b of the portion of the operation dial 84 covered with the cover 85, a display “stop” indicating the closed mode (see FIG. 3), a display indicating each flow rate in the tuning mode, and each flow rate in the continuous mode. Each display is visually recognized from a window 85a provided on the z positive direction side of the cover 85 in accordance with the rotational position of the flow rate adjusting plate 81. Accordingly, the user can check the current mode and the current flow rate setting value of the integrated valve 1 very easily even though the configuration is simple. When the flow rate setting is decreased, the operation dial 84 is rotated counterclockwise in both the tuning mode and the continuous mode. Further, in this embodiment, the stopper (not shown) makes it impossible to switch from the closed mode to the continuous mode by the rotation of the counterclockwise operation dial 84 in FIG. 2, and the clockwise operation dial 84 in FIG. By making it impossible to switch from the continuous mode to the closed mode due to the rotation of the operation dial, erroneous operation of the operation dial 84 and waste of gas due to erroneous operation are reduced.

  Any gas that has passed through the tuning orifice 81 a or the continuation orifice 81 b flows into a common chamber 88 formed between the flow rate adjusting plate 81 and the support member 83. The common chamber 88 is connected via a final discharge connecting passage 106 formed in the extending member 100 and a final discharge gap passage 107 formed between the columnar portion 70 a of the breathing synchronization unit 70 and the extending member 100. It communicates with the final discharge passage 103. That is, in any of the tuning mode and the continuous mode, the gas whose flow rate is adjusted by the tuning orifice 81a or the continuous orifice 81b is the common chamber 88, the final discharge connection passage 106, the final discharge gap passage 107, and the final discharge passage. It passes through the discharge passage 103 and is discharged from the nozzle 90.

  The final discharge gap passage 107 is formed of a gap between the breathing synchronization portion 70 and the extending member 100 between the two O-rings 110, as in the synchronization gap passage 101 (see FIG. 7). By doing in this way, it becomes possible to arrange | position the nozzle 90 to the other side (x negative direction side) of the flow volume adjustment part 80, without requiring a complicated process. That is, the flow rate adjusting unit 80 having the operation dial 84 and the nozzle 90 to which the tube connected to the cannula is connected can be arranged at positions that are easy to use.

  In the present embodiment, the respiratory synchronization unit 70 is disposed on the z positive direction side of the second pressure adjustment unit 60, and the flow rate adjustment unit 80 is disposed on the x positive direction side of the second pressure adjustment unit 60 and the respiratory synchronization unit 70. By disposing the gas, it is possible to efficiently lead the gas to the flow rate adjusting unit 80 from both the second pressure adjusting unit 60 and the respiratory synchronization unit 70. In particular, since the degree of freedom of arrangement of the tuning connection passage 102 and the continuous connection passage 105 and the degree of freedom of the diameter of the flow rate adjusting plate 81 are increased, it is possible to set the flow rate more finely than before. . That is, since more tuning orifices 81a and continuous orifices 81b can be arranged on the flow rate adjusting plate 81 than in the past, in this embodiment, there are 7 levels in the tuning mode and 8 levels in the continuous mode. A fine flow rate setting is realized.

  Moreover, since the rotation center of the flow rate adjusting plate 81 can intersect with the z-axis by adopting such an arrangement, as shown in FIGS. 1 to 3, a position where the operation dial 84 can be easily picked and turned and It can be placed in a posture. That is, in the present embodiment, the operation dial 84 can be picked from the side and rotated as it is with respect to the z axis that is the axial direction (longitudinal direction) of an oxygen cylinder or the like that is the gas supply source 2. In addition, the shape and size of the operation dial 84 can also be set to a shape that prioritizes usability.

  Furthermore, in the present embodiment, the protruding direction of the flow rate adjusting unit 80 is made substantially parallel to the protruding direction of the second protruding portion 12, and the protruding direction of the nozzle 90 is made substantially parallel to the protruding direction of the first protruding portion 11. Thus, the protruding direction of the protruding portion is aligned, and the integrated valve 1 is configured to be compact and easy to hold. In the present embodiment, the rotation center of the flow rate adjusting plate 81 is substantially orthogonal to the viewing direction of the display unit 40 a of the pressure gauge 40, so that the operation dial 84 can be checked while checking the display unit 40 a of the pressure gauge 40. Easy to operate.

  FIG. 9 is a view showing a state in which the extending member 100 is separated from the main body 10. In this embodiment, since the breathing synchronization unit 70 and the flow rate adjustment unit 80 can be easily removed from the main body 10 together with the extending member 100 in this way, maintenance is facilitated. Furthermore, in this embodiment, the filling port 30, the pressure gauge 40, the first pressure adjustment unit 50, and the second pressure adjustment unit 60 are individually provided from the main body 10 as a unit by devising the arrangement and posture of each unit. It is removable. That is, since the first pressure adjusting unit 50 cannot be removed unless the second pressure adjusting unit 60 is removed, parts can be easily replaced or repaired. Similarly, the breathing synchronization unit 70 and the flow rate adjustment unit 80 can also be individually removed from the extending member 100 for maintenance.

  Further, in the present embodiment, as shown in FIG. 9, it is possible to provide an original valve 120 having a check valve structure that opens and closes, for example, by attaching and detaching the extending member 100 at the distal end portion of the fourth projecting portion 14. It has become. That is, for example, the original valve 120 has substantially the same configuration as the filling port 30, and a protrusion is provided on the extending member 100 or the breathing synchronization unit 70, and when the extending member 100 is attached to the main body 10, the protrusion The valve body of the original valve 120 may be pressed and moved so that the original valve 120 is opened. In this case, since the accessory inspection based on the High Pressure Gas Safety Law / Container Safety Regulations can be received only by the main body 10 part, the breathing synchronization unit 70 and the flow rate adjustment unit 80 that require delicate adjustments are provided. It is possible to inspect with a unique method and a unique cycle. Thereby, since inspection and maintenance compliant with various laws and regulations can be performed efficiently, the performance of the integrated valve 1 can be stably maintained over a long period of time.

  Further, in this embodiment, instead of the extending member 100 provided with the breathing synchronization unit 70 and the flow rate adjusting unit 80, for example, an extending member provided only with the flow rate adjusting unit 80 may be attached to the main body 10. It has become. That is, the integrated valve 1 of the present embodiment can be easily changed to a configuration according to the needs of the user.

  By adopting such a configuration, each part can be arranged efficiently, so that it is possible to adjust the flow rate with high accuracy and to make the integrated valve 1 compact and further improve usability. . That is, while adopting a two-stage pressure adjustment and adopting a configuration in which the flow rate is adjusted after breathing synchronization, the integrated valve 1 can be made compact. In addition, the flow rate adjusting unit 80 that requires an operation by the user can be arranged at a position where it can be easily operated.

In this way, the dimension of the integrated valve 1 in the fourth direction (z positive direction) can be shortened, and for example, the first protrusion 11 and the second protrusion 12 can be effectively used as handles. can do. In addition, since a space can be secured in the central portion of the main body 10, the degree of freedom in arranging gas passages and pressure gauges can be increased.

  The second direction and the third direction are opposite to each other. By doing so, it is possible to make the first protruding portion 11 and the second protruding portion 12 easy to use as a handle while making the integrated valve 1 compact by aligning the directions of the protruding portions.

By doing in this way, while arrange | positioning the flow volume adjustment part 80 in the position where it is easy to operate, the integral valve | bulb 1 can be comprised compactly by aligning the direction of a protrusion part. Moreover, also when the 1st protrusion part 11 and the 2nd protrusion part 12 are used as a handle, the flow volume adjustment part 80 can be prevented from getting in the way.

  The flow rate adjusting unit 80 includes an operation dial 84 for setting a flow rate, and the operation dial 84 is arranged to rotate around the fifth direction. By doing in this way, the operation dial 84 can be arranged in a position and posture that are easy to pick and rotate.
