Description

Technical Field

[0001] This disclosure relates to a remote control for an oxygen concentration apparatus. Background Technology

[0002] Previously, an oxygen concentrator including a remote control was known (see Patent Document 1). The remote control has the function of changing the set value of the oxygen supply in the oxygen concentrator through remote operation. The remote control can change the set value of the oxygen supply by performing operations 1) to 3) such as 1) the user picks up the remote control, 2) pressing the confirmation button set on the remote control, and 3) confirming the status of the oxygen concentrator sent from the oxygen concentrator to the remote control.

[0005] Patent Document 1: Japanese Patent No. 5571697 Summary of the Invention

[0006] The technical problem that the invention aims to solve

[0007] In previous remote controls used for oxygen concentrators, when changing the oxygen supply setting, it was necessary to press the confirmation button first to establish communication between the remote control and the oxygen concentrator and to confirm the status of the oxygen concentrator, which increased the number of times the remote control needed to be operated.

[0008] The purpose of this disclosure is to reduce the number of times a user operates the remote control in an oxygen concentration device that includes a remote control.

[0009] Technical solutions adopted to solve technical problems

[0010] (1) The remote control disclosed herein is a remote control for remotely operating an oxygen concentration device, comprising: a main body; an operation button disposed on the main body; a communication unit capable of communicating with the oxygen concentration device; a control unit controlling the communication unit; and a first detection unit detecting when a user grasps the main body, the first detection unit outputting a first signal to the control unit when the user grasps the main body, and the control unit establishing communication between the communication unit and the oxygen concentration device when the first signal is input.

[0011] In the remote control of this disclosure, the control unit enables the communication unit to establish communication with the oxygen concentration device based on the detection result of the first detection unit. Therefore, with the remote control of this disclosure, communication between the remote control and the oxygen concentration device can be established even if the user does not press the confirmation button while holding the remote control. Therefore, the remote control of this disclosure can suppress the number of times the user operates the remote control.

[0012] (2) In the remote control of (1) of this disclosure, preferably, it further includes: a cover that is movable between a closed position covering the operation button and an open position exposing the operation button; and a second detection unit that detects that the cover has moved to the closed position, and when the second detection unit detects that the cover has moved to the closed position, the control unit cuts off the input of the first signal to the control unit.

[0013] In the remote control with the above-described structure, the remote control utilizes a cover provided on the remote control for the oxygen concentration device to prevent accidental operation. Based on the detection result of the cover's position by the second sensor, the remote control's function can be stopped, thus eliminating the need for additional operation to stop the remote control's function. Therefore, the remote control according to this disclosure can stop the remote control's function without increasing the number of times the user operates the remote control. Furthermore, in the structure with the first detection unit, the power consumption of the remote control can be suppressed.

[0014] (3) In the remote control of (2) of this disclosure, it is preferable that the control unit allows the input of the first signal when the second detection unit detects that the cover has moved from the closed position.

[0015] The remote control with the above-described structure utilizes a cover that has always been installed to prevent accidental operation. Based on the detection result of the cover's position by the second sensor, the communication unit can be kept in a communicable state. Therefore, the remote control according to this embodiment can keep the communication unit in a communicable state without increasing the number of times the user operates the remote control.

[0016] (4) In the remote control of the manner described in (1) to (3) of this disclosure, it is preferable that it further includes a storage unit storing a set value of the oxygen supply amount in the oxygen concentrator, the operation buttons including an increase button for increasing the set value and a decrease button for decreasing the set value, the control unit adding a predetermined reference amount to the set value to update the set value each time the increase button is operated without waiting for the arrival of information related to the oxygen supply amount from the oxygen concentrator at the time of operation, and subtracting the predetermined reference amount from the set value to update the set value each time the decrease button is operated without waiting for the arrival of information related to the oxygen supply amount from the oxygen concentrator at the time of operation.

[0017] In conventional remote controls, when changing the oxygen supply setting, confirmation is required every time the setting is changed by one level, based on the information sent from the oxygen concentrator. In other words, conventional remote controls are designed to accept only the first change in a series of subsequent changes, resulting in a longer waiting time when changing the oxygen supply setting.

[0018] In the remote control with the above-described structure, the control unit updates the setpoints without waiting for information from the oxygen concentrator each time the increase and decrease buttons are operated. Therefore, by repeatedly operating the increase and decrease buttons, the control unit can complete the setpoint changes, which were previously done in multiple steps, all at once. Thus, the remote control according to this disclosure can reduce the user's operation waiting time.

[0019] (5) In the remote control of the manner described in (4) of this disclosure, preferably, the storage unit also stores an initial value related to the set value, and if the increase button or the decrease button is operated before the control unit obtains the operation information of the oxygen concentrator via the communication unit, when the increase button is operated for the first time, the predetermined reference amount is added to the initial value to update the set value without waiting for the information related to the set value from the oxygen concentrator to arrive, and when the decrease button is operated for the first time, the predetermined reference amount is subtracted from the initial value to update the set value without waiting for the information related to the set value from the oxygen concentrator to arrive.

[0020] In the remote controller with the above-described structure, the control unit can update the setpoint based on the initial setpoint without waiting for information from the oxygen concentrator. Therefore, the remote controller according to this disclosure can perform the operation of changing the setpoint before obtaining the current oxygen supply from the oxygen concentrator, thereby reducing the waiting time for user operation.

[0021] (6) In the remote controller of the manner described in (4) or (5) of this disclosure, it is preferable to further include a display unit that displays the setting value, and the control unit updates the setting value displayed on the display unit each time the setting value is updated.

[0022] In the remote control with the above structure, the user can easily grasp the current oxygen supply setting value by checking the display.

[0023] (7) In the remote control of the manner described in (6) of this disclosure, it is preferable that, during the operation of the oxygen concentration device, the control unit obtains the oxygen supply amount via the communication unit, and when the set value is different from the oxygen supply amount, the set value is flashed on the display unit, and when the set value is consistent with the oxygen supply amount, the set value is illuminated on the display unit.

[0024] In the remote control with the above-described structure, the user can easily confirm whether the current oxygen supply is consistent with the set value by checking the display unit. Furthermore, according to the remote control of this disclosure, the user can easily confirm that the oxygen supply is changing by checking the flashing display of the set value.

[0025] (8) In the remote control of the manner described in (7) of this disclosure, it is preferable that when the oxygen concentrator is in operation, the control unit obtains the operation information of the oxygen concentrator via the communication unit, and when the first signal is input to the control unit, the oxygen supply is displayed on the display unit.

[0026] In the remote control with the above structure, the user can easily check the oxygen supply simply by picking up the remote control. Attached Figure Description

[0037] Hereinafter, with reference to the accompanying drawings, the remote controller of this disclosure and an oxygen concentration apparatus including the remote controller of this disclosure will be described in detail. Furthermore, this disclosure is not limited to these examples, but is shown in the form of claims, and is intended to include all changes within the meaning and scope of the claims.

[0038] [Overall structure of the oxygen concentration unit]

[0039] Figure 1 This is a three-dimensional schematic diagram showing the appearance of an oxygen concentration unit. Figure 2 This is an explanatory diagram of the overall structure of the oxygen concentration unit. Figure 3 yes Figure 2 The diagram shows the oxygen generation unit and the oxygen supply unit. Figure 1 as well as Figure 2 The oxygen concentrator M shown is a device that generates high-concentration oxygen, containing oxygen at a concentration higher than that in the air, and supplies it to a user. In this embodiment, the oxygen concentrator M supplies the user with high-concentration oxygen generated using an adsorbent that selectively or preferentially adsorbs nitrogen. The oxygen concentrator M is used, for example, in home oxygen therapy, where high-concentration oxygen is provided to users such as patients with respiratory illnesses.

[0040] like Figure 1 as well as Figure 2 As shown, the oxygen concentration unit M includes a remote control 40. The remote control 40 is an example of a remote control disclosed herein. The remote control 40 enables a user to remotely operate the oxygen concentration unit M.

[0041] like Figure 1 as well as Figure 2As shown, the oxygen concentration device M includes a device body 10, an oxygen generation unit 11, an oxygen supply unit 12, a main display unit 13, a main operation unit 14, a main control unit 30, and a remote control 40. The oxygen generation unit 11, the oxygen supply unit 12, and the main control unit 30 are housed in a casing 10a of the device body 10. Furthermore, in this description, the device body 10, which is the main part of the oxygen concentration device M, is also referred to as the oxygen concentration device 10.

[0042] [Oxygen Concentration Unit]

[0043] The oxygen concentration unit M (unit body 10) separates nitrogen from the feed air to generate high-concentration oxygen via VPSA (Vacuum Pressure Swing Adsorption System). Figure 2 as well as Figure 3 As shown, the main body 10 draws in raw air from the outside into the compressor 20, where it is compressed. The compressed raw air is then supplied via a control valve 21 to one of a pair of adsorption cylinders 22 (22a, 22b). Each adsorption cylinder 22a, 22b contains an adsorbent that selectively or preferentially adsorbs nitrogen from the raw air. Nitrogen in the raw air supplied to one of the adsorption cylinders 22a, 22b is adsorbed by this adsorbent. Zeolite, for example, can be used as an adsorbent that selectively or preferentially adsorbs nitrogen.

[0044] The oxygen concentration in the gas (high-concentration oxygen) discharged from one of the adsorption cylinders 22a and 22b is higher than that in the air (for example, about 88-95%). The high-concentration oxygen discharged from one of the adsorption cylinders 22a and 22b is stored in the oxygen container 25 via the control valve 24. Each of the adsorption cylinders 22a and 22b is equipped with a control valve 23.

[0045] The oxygen concentration apparatus M (apparatus body 10) illustrated in this embodiment comprises an oxygen generation unit 11 that generates high-concentration oxygen, consisting of a compressor 20, control valves 21, 23, and 24, a pair of adsorption cylinders 22a and 22b, and a vacuum pump 15. An oxygen supply unit 12 that supplies high-concentration oxygen to the user comprises an oxygen container 25, a pressure reducing valve 26 (described later), a control valve 27, a flow sensor 28, and an oxygen concentration sensor 29. The compressor 20 and vacuum pump 15 in this embodiment are part of a pressurization-vacuum type fluid machinery capable of pressurizing and suctioning gases such as air using a single device. Alternatively, in the oxygen concentration apparatus M of this embodiment, the compressor 20 and vacuum pump 15 may also be composed of independent fluid machinery.

[0046] A control valve 21 is located in the flow path between the compressor 20 and a pair of adsorption cylinders 22a and 22b, and is connected to adsorption cylinders 22a and 22b respectively. The control valve 21 switches between the state of supplying compressed air discharged from the compressor 20 to one adsorption cylinder 22a and the state of supplying compressed air discharged from the compressor 20 to the other adsorption cylinder 22b.

[0047] Control valve 24 is located in the flow path between a pair of adsorption cylinders 22a and 22b and oxygen container 25, and is connected to adsorption cylinders 22a and 22b respectively. Control valve 24 switches between the state of supplying high-concentration oxygen after passing through adsorption cylinder 22a to oxygen container 25 and the state of supplying high-concentration oxygen after passing through adsorption cylinder 22b to oxygen container 25.

[0048] When compressed air is supplied to one of the adsorption cylinders 22a and 22b, and nitrogen adsorption occurs within that cylinder, the other adsorption cylinder 22b is closed by control valves 21 and 24. At this time, control valve 23 of the other adsorption cylinder 22b is set to the "open" state, and the pressure in that cylinder is reduced by vacuum pump 15. As a result, the pressure in the other adsorption cylinder 22b decreases from a pressurized state to a negative pressure state, and the nitrogen adsorbed on the adsorbent contained within it is released from the adsorbent due to the pressure reduction and discharged to the outside. Furthermore, when compressed air is supplied to the other adsorption cylinder 22b, and one adsorption cylinder 22a is closed by control valves 21 and 24, control valve 23 of that adsorption cylinder 22a is also set to the "open" state, and nitrogen is discharged from that adsorption cylinder 22a to the outside by vacuum pump 15. In addition, this embodiment illustrates an oxygen concentrator M of the VPSA method in which, while air compressed by the compressor 20 is supplied to one adsorption cell 22a, the other adsorption cell 22b is attracted by the vacuum pump 15. However, an oxygen concentrator including the remote control of this disclosure may also be of the PSA (Pressure Swing Adsorption System) method in which, while air compressed by the compressor is supplied to one adsorption cell, the pressure is reduced by opening the other adsorption cell to the atmosphere.

[0049] High-concentration oxygen stored in oxygen container 25 is supplied to the user via pressure reducing valve 26, control valve 27, flow sensor 28, oxygen concentration sensor 29, tube T, and sleeve C. Pressure reducing valve 26 reduces the pressure of the high-concentration oxygen to the desired pressure. Control valve 27 regulates the flow rate of the high-concentration oxygen according to its opening degree. Flow sensor 28 detects the flow rate of the high-concentration oxygen supplied through control valve 27. The detected flow rate is fed back to control valve 27 via main control unit 30. Oxygen concentration sensor 29 detects the oxygen concentration in the high-concentration oxygen. Tube T connects the downstream side of control valve 27 to sleeve C. Sleeve C has a pair of short tubes (not shown) inserted into the user's nostrils, through which high-concentration oxygen is supplied into the user's nostrils.

[0050] [Main Control Department]

[0051] The main control unit 30 controls the drive operation of the compressor 20 and the opening and closing operations of various control valves 21, 23, 24, 27, etc. The main control unit 30 includes a main arithmetic unit 31, a main storage unit 32, and a main communication unit 33. The main control unit 30 executes the program installed in the main storage unit 32 through the main arithmetic unit 31, thereby performing its prescribed functions. The main arithmetic unit 31 is composed of a CPU that acts as the processing center. The main storage unit 32 is composed of memory, including ROM and RAM. The ROM stores the control operation program of the main arithmetic unit 31, and the RAM is temporarily written to or read from when the main arithmetic unit 31 executes control operations. Alternatively, the main control unit 30 can also be implemented using LSI, ASIC, FPGA, or other hardware.

[0052] The main storage unit 32 stores the set value VS of the oxygen supply amount VQ before the device main body 10 was about to stop. Furthermore, when the device main body 10 is operated again, the main control unit 30 uses the set value VS from the previous operation to adjust the oxygen supply amount VQ.

[0053] The main communication unit 33 transmits and receives signals with the remote controller 40. In other words, the main control unit 30 communicates with the remote controller 40 via the main communication unit 33.

[0054] The main display unit 13 and the main operation unit 14 are disposed on the outer surface of the housing 10a. The main display unit 13 displays the operation information J of the main body 10 to the user. The operation information J includes the operation status ST of the main body 10, the current oxygen supply VQ of the main body 10, and the set value VS of the oxygen supply VQ. The operation status ST is information related to the operation status of the main body 10, and is related to either the operation or the shutdown state. The main display unit 13 may be composed of, for example, a CRT, a liquid crystal display panel, etc.

[0055] The main operating unit 14 includes operation buttons for users to perform operations such as operation and initial settings on the main unit 10. The main operating unit 14 includes, for example, a power on / off button, a mode switch button, and an initial setting button (not shown).

[0056] [Remote Control]

[0057] Figure 4 This is a schematic top view of the remote control of this disclosure. Figure 4 The left side shows the non-use status of the remote control 40. Figure 4 The right side shows the status of the remote control 40 when in use. For example... Figure 4 As shown, the remote control 40 includes a main body 41, operation buttons 42, a cover 43, a display unit 44, and a battery 45.

[0058] The main body 41 is, for example, a shell formed in the shape of a cuboid. An operation button 42 is provided on the front surface of the main body 41. The operation button 42 is a button operated by the user. The operation button 42 includes a power-on button 42a for turning on the power to the main body 10, a power-off button 42b for turning off the power to the main body 10, an increase button 42c for increasing the oxygen supply VQ, and a decrease button 42d for decreasing the oxygen supply VQ. In the oxygen concentration device M, when the increase button 42c is pressed, the set value VS of the oxygen supply VQ increases, resulting in an increase in the oxygen supply VQ of the main body 10. Furthermore, when the decrease button 42d is pressed, the set value VS of the oxygen supply VQ decreases, resulting in a decrease in the oxygen supply VQ of the main body 10. Additionally, as... Figure 4 As shown, the operation buttons 42 of the remote control 40 disclosed herein do not include the confirmation button disclosed in the aforementioned Patent Document 1.

[0059] The cover 43 is slidably disposed on the front surface of the main body 41. In this embodiment, the cover 43 is constructed from a flat plate member that is generally rectangular. The cover 43 is configured to cover the closed position P1 of the operation button 42 relative to the main body 41. Figure 2 The position shown on the left) and the open position P2 that exposes the operation button 42 ( Figure 2 The cover 43 can move between the positions shown on the right. Specifically, the left and right edges of the cover 43 are slidably supported on the front of the main body 41.

[0060] When the cover 43 is in the closed position P1, it covers all the operation buttons 42. When the user is not operating the operation buttons 42 (when the remote control 40 is not used), the cover 43 is slid to the closed position P1. This prevents the user from accidentally operating the operation buttons 42.

[0061] When cover 43 is in the open position P2, all operation buttons 42 are exposed. When the user operates operation buttons 42 (when using remote control 40), cover 43 is slid to the open position P2. In this state, the user can operate operation buttons 42.

[0062] Furthermore, the form of the cover 43 is not limited to that shown in this embodiment. For example, the cover 43 may also be configured to swing relative to the main body 41. In addition, the cover 43 may cover at least a portion of the operation button 42 when in the closed position and expose it when in the open position.

[0063] The display unit 44 is composed of a display device such as an organic EL display or a liquid crystal display. The display unit 44 displays the operation information J obtained from the device body 10 through communication with the device body 10. The operation information J includes, for example, information indicating whether the oxygen concentration device M (device body 10) is in operation or stopped (operation status ST), the current supply amount of high-concentration oxygen supplied to the user (oxygen supply amount VQ), and the set value VS of the oxygen supply amount VQ, etc.

[0064] The remote control 40 includes a battery 45 that serves as a power source. In this embodiment, the remote control 40 has two batteries 45 detachably installed inside the main body 41. Each power source 45 is, for example, a dry cell battery.

[0065] [Control Department]

[0066] Figure 5 This is a control block diagram of the remote control disclosed herein. For example... Figure 4 as well as Figure 5 As shown, the remote controller 40 includes a control unit 50. The control unit 50 is mounted on a substrate built into the main body 41. The control unit 50 is composed of a microcomputer including a processor (arithmetic unit 51) such as a CPU and a memory (storage unit 52) ​​such as RAM and ROM. The control unit 50 executes the program installed in the storage unit 52 through the arithmetic unit 51, thereby performing the prescribed functions. The control unit 50 may also be implemented using LSI, ASIC, FPGA, or other hardware.

[0067] The control unit 50 also includes a communication unit 53. The control unit 50 performs communication control of the communication unit 53. The communication unit 53 can communicate with the main communication unit 33 of the device main body 10. The communication unit 53 can communicate wirelessly with the main communication unit 33, for example, via a near-field wireless communication method (Bluetooth, etc.). The communication unit 53 can also communicate with the device main body 10 via other communication methods, such as infrared communication. In addition, this embodiment illustrates the case where the device main body 10 communicates wirelessly with the remote controller 40, but the communication method between the device main body 10 and the remote controller 40 can also be wired communication.

[0068] Operation button 42 is connected to control unit 50. When power button 42a is pressed, power signal Sa is input to control unit 50. When power signal Sa is input to control unit 50, arithmetic unit 51 outputs power signal SA to main communication unit 33 (main control unit 30) via communication unit 53. When power button 42b is pressed, power-off signal Sb is input to control unit 50. When power-off signal Sb is input to control unit 50, arithmetic unit 51 outputs power-off signal SB to main communication unit 33 (main control unit 30) via communication unit 53. When power signal SA is input, main control unit 30 controls device main body 10 (see reference 10)... Figure 2 The power supply to the main unit 10 (refer to) is turned on. When a power-off signal SB is input, the main control unit 30 switches the device main unit 10 (refer to) to the on position. Figure 2 The power supply to the device should be set to off.

[0069] When the increment button 42c is pressed, an increment signal Sc is input to the control unit 50. When the increment signal Sc is input to the control unit 50, the arithmetic unit 51 increments the setting value VS to update it. Specifically, the arithmetic unit 51 multiplies the reference value VX stored in the storage unit 52 by the number of times the increment signal Sc is input (i.e., the number of times the increment button 42c is pressed) and adds the result to the setting value VS stored in the storage unit 52, thereby updating the setting value VS. Then, the arithmetic unit 51 outputs the updated setting value VS to the main communication unit 33 (main control unit 30) via the communication unit 53.

[0070] When the decrement button 42d is pressed, a decrement signal Sd is input to the control unit 50. When the decrement signal Sd is input to the control unit 50, the arithmetic unit 51 decrements the setting value VS to update it. Specifically, the arithmetic unit 51 subtracts the value obtained by multiplying the reference amount VX stored in the storage unit 52 by the number of times the decrement signal Sd is input (i.e., the number of times the decrement button 42d is pressed) from the setting value VS stored in the storage unit 52, thereby updating the setting value VS. Then, the arithmetic unit 51 outputs the updated setting value VS to the main communication unit 33 (main control unit 30) via the communication unit 53.

[0071] When an updated setting value VS is input, the main control unit 30 updates the setting value VS stored in the main storage unit 32, and activates the device main body 10 (refer to...) Figure 2 Perform the action of changing the oxygen supply VQ to conform to the updated setting value VS.

[0072] [First Inspection Department and Second Inspection Department]

[0073] like Figure 4 as well as Figure 5As shown, the remote controller 40 also includes a first detection unit 61 and a second detection unit 62.

[0074] The first detection unit 61 detects the state in which the user picks up the main body 41 (also known as the gripping state). In this embodiment, the first detection unit 61 is composed of an accelerometer. Hereinafter, the first detection unit 61 is also referred to as the accelerometer 61. In addition, the first detection unit 61 can be composed of any sensor capable of detecting the state in which the user picks up the main body 41, and is not limited to an accelerometer. For example, the first detection unit 61 may also be a temperature sensor that detects the user's body temperature, a pressure sensor that detects the gripping pressure of the user on the main body 41, or an electrostatic sensor that detects the static electricity carried by the user, etc.

[0075] Accelerometer 61 detects the acceleration of the main body 41 generated when the user grips it. Accelerometer 61 is connected to control unit 50. When accelerometer 61 detects the user gripping the main body 41, it outputs a first signal S1 to control unit 50.

[0076] When the first signal S1 is input from the accelerometer 61 to the control unit 50, the arithmetic unit 51 determines that the user requests confirmation of the status of the device main body 10. In this case, the arithmetic unit 51 outputs a confirmation signal S0 to the main communication unit 33 (main control unit 30) via the communication unit 53. Upon receiving the confirmation signal S0, the main control unit 30 sends operation information J to the control unit 50, thereby establishing a connection between the remote controller 40 and the device main body 10 (see reference 50). Figure 2 Communication between them.

[0077] The second detection unit 62 detects when the cover 43 is in the closed position P1. In this embodiment, the second detection unit 62 includes a magnetic sensor 62a mounted on a substrate inside the main body 41 and a magnet 62b disposed on the cover 43. In this embodiment, the magnet 62b is a permanent magnet. The magnet 62b is fixed to the cover 43 and moves together with the cover 43.

[0078] A magnetic sensor 62a is installed near and opposite the magnet 62b when the cover 43 is in the closed position P1. When the cover 43 is in the closed position P1, the magnetic sensor 62a detects the magnetic force of the magnet 62b. Furthermore, the magnetic sensor 62a detects movement of the cover 43 from the closed position P1. If the magnetic sensor 62a detects movement of the cover 43 from the closed position P1, the control unit 50 determines that the user has moved the cover 43 to the open position P2. Upon detecting movement of the cover 43 from the closed position P1, the control unit 50 allows the input of a first signal S1.

[0079] If the magnetic sensor 62a detects the magnetic force of the magnet 62b (i.e., if no movement of the cover 43 from the closed position P1 is detected), the control unit 50 determines that the cover 43 is in the closed position P1. In this case, the control unit 50 cuts off the input of the first signal S1 to the control unit 50.

[0080] The magnetic sensor 62a is connected to the control unit 50. If the magnetic sensor 62a does not detect movement of the cover 43 from the closed position P1, the arithmetic unit 51 determines that the cover 43 is in the closed position P1 (i.e., the user is not using the remote control 40) and stops the communication unit 53. Furthermore, at this time, the arithmetic unit 51 does not allow the input of the first signal S1 from the accelerometer 61. The arithmetic unit 51 may also stop supplying power to the accelerometer 61 at this time.

[0081] When the magnetic sensor 62a detects that the cover 43 has moved from the closed position P1, the arithmetic unit 51 determines that the user has moved the cover 43 to the open position P2 (i.e., the user is using the remote control 40) and activates the communication unit 53. At this time, the arithmetic unit 51 allows the input of the first signal S1 from the accelerometer 61. The arithmetic unit 51 can also begin supplying power to the accelerometer 61 at this time.

[0082] The display unit 44 is connected to the control unit 50. Whenever operation information J (operation status ST and oxygen supply VQ) is sent from the main control unit 30 (main communication unit 33) of the main body 10 to the control unit 50, the calculation unit 51 displays the received operation information J on the display unit 44. Whenever the setting value VS stored in the storage unit 52 is updated, the calculation unit 51 displays the updated setting value VS on the display unit 44.

[0083] [Steps to confirm the operating status of the oxygen concentrator when using a conventional remote control]

[0084] Figure 6 This diagram illustrates the steps for confirming the operating status of the oxygen concentrator when using a conventional remote control. The operating procedures for confirming the operating status of the oxygen concentrator using a conventional remote control are explained here.

[0085] Figure 6 The diagram illustrates the operating procedures for verifying the operational status of the oxygen concentration unit using a conventional remote control. For example... Figure 6 As shown, when using a conventional remote control to confirm the operating status of the oxygen concentrator, the user first picks up the remote control (S101). Next, the user presses the confirmation button located on the remote control (S102). In conventional remote controls, pressing the confirmation button conveys the user's intention to confirm the operating status to the oxygen concentrator. When the confirmation button is pressed, a first signal is output to the control unit.

[0086] The control unit of the remote control detects the first signal (i.e., the confirmation button is pressed) (S201). Next, the control unit activates the communication unit (S202). Then, the control unit sends a confirmation signal to the oxygen concentrator via the communication unit (S203). The confirmation signal is a signal conveying the intention to confirm the operating status to the oxygen concentrator. In conventional remote controls, pressing the confirmation button triggers communication between the remote control and the oxygen concentrator. In other words, in conventional remote controls, simply picking up the remote control does not establish communication between the remote control and the oxygen concentrator.

[0087] The main control unit of the oxygen concentrator receives a confirmation signal (S301). Next, the main control unit outputs operation information to the remote controller (S302). In addition, the operation information output here includes the operation status of the oxygen concentrator (operating or stopped), the set value of the oxygen supply in the oxygen concentrator, and the current oxygen supply in the oxygen concentrator.

[0088] The control unit of the remote controller receives the operation information (S204). At this time, communication between the remote controller and the oxygen concentration unit is established. With communication established, the remote controller can send and receive signals with the oxygen concentration unit. Next, the control unit displays the received operation information on the display unit (S205).

[0089] The user confirms the operating information displayed on the display (S103). By confirming that the operating information is displayed on the display, the user can determine that communication between the remote control and the oxygen concentrator has been established. Furthermore, the user can grasp the operating status of the oxygen concentrator based on the operating information displayed on the display. As such, the user can use a conventional remote control to confirm the operating status of the oxygen concentrator.

[0090] [Steps for confirming the operating status of the oxygen concentration device when using the remote control of this embodiment]

[0091] Figure 7 This is an explanatory diagram illustrating the steps for confirming the operating status of the oxygen concentration device when using the remote control of this disclosure. Next, the operation steps for confirming the operating status of the oxygen concentration device M (device body 10) using the remote control 40 of this embodiment will be explained. Additionally, here, the operation steps for confirming the operating status of the oxygen concentration device M (device body 10) using the cover 43 of the remote control 40 will be explained. Figure 4 The operation steps starting from the open position P2 will be explained. If the cover 43 of the remote control 40 is configured in the closed position P1, the user moves the cover 43 from the closed position P1 to the open position P2 before starting the operation steps described below.

[0092] Figure 7 The diagram illustrates the operating steps for confirming the operational status of the main body 10 using the remote control 40. For example... Figure 7As shown, when using the remote control 40 to confirm the operating status of the main body 10, the user first picks up the remote control 40 (S101). At this time, the acceleration sensor 61 detects the user's gripping state of the remote control 40 and outputs a first signal S1. Therefore, the user using the remote control 40 of this embodiment does not need to press the confirmation button (see Patent Document 1).

[0093] The control unit 50 of the remote control 40 detects the first signal S1 (S201) output from the acceleration sensor 61. When the first signal S1 is input, the control unit 50 determines that the user has picked up the remote control 40.

[0094] Next, the control unit 50 activates the communication unit 53 (S202). Then, the control unit 50 sends a confirmation signal S0 to the device body 10 via the communication unit 53 (S203). Thus, when the user picks up the remote control 40, the remote control 40 outputs a confirmation signal S0 to the device body 10 to convey the intention to confirm the operating status.

[0095] When the control unit 50 sends a confirmation signal S0, the main control unit 30 of the device body 10 receives the confirmation signal S0 (S301). Then, the main control unit 30 outputs operation information J to the remote controller 40 (S302). In addition, the operation information J output here includes information such as the operation status ST of the device body 10 (operating or stopped) and the current oxygen supply VQ.

[0096] When operation information J is output from the main control unit 30, the control unit 50 receives the operation information J (S204). Furthermore, when the control unit 50 receives the operation information J, communication is established between the remote controller 40 and the device main unit 10. Thus, the process of establishing communication between the remote controller 40 and the device main unit 10 includes the following series of steps: 1) activating the communication unit 53 using a first signal S1 as a trigger; 2) sending an acknowledgment signal S0 from the communication unit 53 to the device main unit 10; 3) sending the operation information J from the device main unit 10 to the communication unit 53; 4) the communication unit 53 receiving the operation information J. Additionally, in the remote controller 40 of this embodiment, after the arithmetic unit 51 sends the acknowledgment signal S0 from the communication unit 53 to the main control unit 30, and before the communication unit 53 receives the operation information J from the main control unit 30, the display unit 44 displays a message indicating that communication is being established.

[0097] Next, the control unit 50 displays the received operation information J on the display unit 44 (S205).

[0098] Next, the user confirms the operation information J displayed on the display unit 44 (S103). The user using the remote control 40 can confirm the operation status of the device body 10 through the above steps.

[0099] As described above, when using the remote control 40 of this embodiment, the operation of pressing the confirmation button (see Patent Document 1), which was previously necessary, can be omitted. Figure 6 The steps shown are (S102). Therefore, compared with conventional remote controls, the remote control 40 of this embodiment can suppress the number of operations.

[0100] [Steps for changing the oxygen supply setting when using a previous remote control]

[0101] Figure 8 This is an explanatory diagram illustrating the steps for changing the oxygen supply setting value when using a conventional remote control. Here, the operating steps for making two-stage changes to the oxygen supply setting value using a conventional remote control are explained. Furthermore, some of the operating steps described here are the same as the previously described operating steps for confirming the operating status of the oxygen concentrator (see [reference]). Figure 6 The operational steps of steps (S101) to (S103) in the process are common. Therefore, the explanation of the common operational steps will be omitted appropriately.

[0102] Figure 8 The diagram illustrates the operating steps for making two-stage changes to the oxygen supply setting using a conventional remote control. For example... Figure 8 As shown, when the oxygen supply setting is changed in two stages, the user confirms the information related to the current oxygen supply displayed on the display (S103). The user confirms the current oxygen supply and determines whether the setting needs to be changed. Here, it is assumed that the user determines that a two-stage setting change (increase or decrease) is required, and the following explanation will be provided.

[0103] When it is determined that a two-level setting change is required, the user first presses the increase or decrease button on the remote control once (S104-1). When the increase or decrease button is pressed once, the control unit of the remote control receives an operation signal for the increase or decrease button. In addition, in conventional remote controls, when the increase or decrease button is pressed multiple times, only the first press is effective, and subsequent presses are ineffective.

[0104] The control unit of the remote control performs the first-level update of the oxygen supply setting value (S206-1).

[0105] The storage unit of the control section stores a reference quantity related to the oxygen supply setting. This reference quantity is the base unit (1 unit) for changing the setting. When the increase button is pressed once, the control section adds the reference quantity to the setting to update the setting. When the decrease button is pressed once, the control section subtracts the reference quantity from the setting to update the setting.

[0106] Next, the control unit sends the updated settings after completing the first stage to the main control unit of the device body (S207).

[0107] Next, the main control unit receives the updated setpoint after the completion of the first stage (S303). Upon receiving the updated setpoint, the main control unit causes the main body of the device to perform an operation to increase or decrease the oxygen supply (first stage) to conform to the increased or decreased setpoint (S304-1).

[0108] After the main control unit causes the main body of the device to complete the action of increasing or decreasing the oxygen supply (first stage), it outputs operation information including the current oxygen supply (S305).

[0109] The control unit receives operation information output from the main control unit (S208). Then, the control unit displays the received operation information on the display unit (S209).

[0110] Next, the user confirms the operating information displayed on the display (S105). After confirming the change of the first-level setting value, the user presses the increase or decrease button a second time (S106).

[0111] If the increase or decrease button is pressed a second time, the control unit of the remote control performs a second-level update of the oxygen supply setting value (S210).

[0112] Next, the control unit sends the updated settings for the second stage to the main control unit of the device body (S211).

[0113] Next, the main control unit receives the updated setpoint after the completion of the second stage (S306). The main control unit causes the main unit to perform an operation to change the oxygen supply (second stage) to conform to the increased or decreased setpoint (S307).

[0114] After the main control unit causes the main body of the device to complete the action of increasing or decreasing the oxygen supply (second stage), it outputs operation information including the current oxygen supply to the control unit again (S308).

[0115] When operation information is output from the main control unit, the control unit receives the operation information (S212). Then, the control unit displays the received operation information on the display unit (S213).

[0116] Next, the user confirms the operating information displayed on the display unit (S107). Thus, the user confirms that the change operation of the second-level setting value has been completed.

[0117] By following the steps above, users can use the same remote control to change the oxygen supply setting in two levels.

[0118] [Steps for changing the oxygen supply setting when using the remote control of this embodiment]

[0119] Figure 9 This is an explanatory diagram illustrating the steps for changing the oxygen supply setting value when using the remote control of this disclosure. Next, the operation steps for changing the oxygen supply VQ setting value VS in two stages using the remote control 40 of this embodiment will be described. Furthermore, some of the operation steps described here are the same as the operation steps for confirming the operating status of the oxygen concentration device M (device body 10) described previously (see...). Figure 7 The operational steps of steps (S101) to (S103) in the process are common. Therefore, the explanation of the common operational steps will be omitted appropriately.

[0120] Figure 9 The diagram illustrates the operation steps for using the remote controller 40 of this embodiment to perform two-level changes to the oxygen supply quantity VQ setting value VS. For example... Figure 9 As shown, when the oxygen supply quantity VQ setting value VS is changed in two stages, the user confirms the current oxygen supply quantity VQ displayed on the display unit 44 (S103). The user confirms the current oxygen supply quantity VQ and determines whether it is necessary to change the setting value VS. Here, assuming the user determines that it is necessary to change the setting value VS in two stages (increase or decrease), the following explanation will be provided.

[0121] When the user wants to increase or decrease the setting value VS by two levels, the user presses the increase button 42c or decrease button 42d on the remote control 40 twice consecutively (S104-2). In the remote control 40, when the increase button 42c and decrease button 42d are pressed multiple times consecutively, not only the first press is effective, but also the second and subsequent presses are effective. Therefore, when the increase button 42c is pressed twice consecutively, the control unit 50 of the remote control 40 receives an increase signal Sc twice, and when the decrease button 42d is pressed twice, the control unit 50 receives a decrease signal Sd twice. The remote control 40 of this embodiment differs from the conventional remote control described above in this respect.

[0122] The control unit 50 of the remote controller 40 updates the set value VS of the oxygen supply quantity VQ (S206-2). In the remote controller 40 of this embodiment, the control unit 50 performs a two-level update of the set value VS at this time.

[0123] The control unit 50 stores a reference quantity VX related to the set value VS of the oxygen supply rate VQ in the storage unit 52. The reference quantity VX is the reference unit (1 unit) when changing the set value VS. For example, when the reference quantity VX is 0.5 (L / min), when the control unit 50 receives two consecutive increase signals Sc, it increases the set value VS by the reference quantity VX multiplied by 2 (the number of times the increase button 42c is pressed), which is 1.0 (L / min), to update the set value VS. Alternatively, when the control unit 50 receives two consecutive decrease signals Sd, it decreases the set value VS by the reference quantity VX multiplied by 2 (the number of times the decrease button 42d is pressed), which is 1.0 (L / min), to update the set value VS.

[0124] Next, the control unit 50 sends the updated setting value VS after completing the two-level update to the device body 10 (S207).

[0125] Next, the main control unit 30 of the device body 10 receives the set value VS after the two-stage update (S303). Based on the updated set value VS, the main control unit 30 causes the device body 10 to perform an action that increases or decreases the oxygen supply amount VQ by two stages at once (S304-2).

[0126] After the main control unit 30 causes the main body 10 to complete the two-stage operation of increasing or decreasing the oxygen supply VQ, it outputs operation information J including the current oxygen supply VQ (S305).

[0127] The control unit 50 receives the operation information J (S208). Then, the control unit 50 displays the received operation information J (operation status ST and oxygen supply VQ) and the updated set value VS after completing the two-stage update on the display unit 44 (S209).

[0128] In the remote controller 40 of this embodiment, if the oxygen supply quantity VQ received by the control unit 50 is inconsistent with the set value VS after the two-stage update, the set value VS is flashed on the display unit 44. Conversely, if the oxygen supply quantity VQ received by the control unit 50 is consistent with the set value VS after the two-stage update, the set value VS is illuminated on the display unit 44.

[0129] Next, the user confirms the operation information J displayed on the display unit 44 (S105). Furthermore, the user confirms that the two-level change operation of the setting value VS has been completed by performing two consecutive operations, including the increase button 42c or the decrease button 42d (S108).

[0130] At this time, if the set value VS is flashing, the user can know that the action of increasing or decreasing the oxygen supply VQ in the main body 10 of the device is in progress. Alternatively, if the set value VS is lit, the user can know that the action of increasing or decreasing the oxygen supply VQ in the main body 10 of the device has been completed.

[0131] Through the steps described above, the user can use the remote control 40 of this embodiment to change the oxygen supply VQ setting value VS of the device body 10 at one time.

[0132] Furthermore, while this embodiment describes the operation steps for changing the setting value VS by two levels at once, the remote control 40 of this disclosure is not limited to two levels and can also perform three or more level changes on the setting value VS at once. Specifically, in step (S104-2), for example, when the user presses the increase button 42c or the decrease button 42d three times consecutively, the remote control 40 can change the setting value VS of the oxygen supply VQ of the device body 10 by three levels at once. In addition, the remote control 40 of this disclosure can also perform a single level change on the setting value VS when the user presses the increase button 42c or the decrease button 42d only once.

[0133] Furthermore, in the remote control 40 of this embodiment, when the main body 10 is in operation, the control unit 50 acquires the operation information J of the main body 10 via the communication unit 53. When the user picks up the remote control 40 while the main body 10 is in operation, a first signal S1 is input from the acceleration sensor 61 to the control unit 50. In this case, the calculation unit 51 displays the oxygen supply amount VQ on the display unit 44. In this case, the user can easily check the oxygen supply amount VQ simply by picking up the remote control 40 while the main body 10 is in operation.

[0134] [A variation of the procedure for changing the oxygen supply setpoint]

[0135] Figure 10 This is an explanatory diagram illustrating a modified example of the steps for changing the oxygen supply setting value when using the remote control of this disclosure. Here, a modified example of the steps for changing the oxygen supply setting value when using the remote control of this embodiment will be described. The remote control 40 of this embodiment can change the oxygen supply VQ setting value VS when the device main body 10 is started from a stopped state. Figure 10 The operating steps are shown.

[0136] Figure 10 The diagram illustrates the operation steps for changing the oxygen supply quantity VQ setting value VS when the device main body 10 is started using the remote controller 40 of this embodiment. Figure 10As shown, when using the remote control 40 of this embodiment to change the set value VS of the oxygen supply quantity VQ when the device main body 10 is started, the user first holds the remote control 40 (S101). At this time, the control unit 50 detects the first signal S1 (S201) and then executes the processing steps (S202) to (S204). In step (S204), the control unit 50 causes the display unit 44 to display a message indicating that communication is being established during the period before communication is established with the device main body 10.

[0137] At this time, the device body 10, which is in a stopped state, receives an acknowledgment signal S0 (S301) and outputs operation information J indicating that the device body 10 is in a stopped state (S302). When the remote controller 40 receives the operation information J indicating that the device body 10 is in a stopped state, communication between the remote controller 40 and the device body 10 is established (S204).

[0138] Next, the user confirms the operating information J indicating that the main body 10 of the device is stopped via the display unit 44 (S103), and then presses the power button 42a (S151). At this time, the control unit 50 is input with a power signal Sa.

[0139] Next, the control unit 50 sends a power-on signal SA to the device body 10 (S251), and causes the display unit 44 to display a flashing "Running" sign indicating that the device body 10 is starting up (in this embodiment, a flashing "Running" sign) (S252). The user confirms that the device body 10 is starting up through the display unit 44 (S152).

[0140] Next, the main control unit 30 of the device body 10 receives the power-on signal SA (S351). Then, the main control unit 30 starts the device body 10 (S352). At this time, the main control unit 30 sends operation information J to the remote controller 40, indicating that the device body 10 has been started.

[0141] Next, when the control unit 50 receives the operation information J indicating that the device main body 10 has been started from the main control unit 30, it causes the display unit 44 to display a display indicating that the device main body 10 is running (in this embodiment, a "running" illuminated display) (S253). In the remote controller 40 of this embodiment, when the device main body 10 is started, the control unit 50 allows receiving the increase signal Sc and decrease signal Sd generated by pressing the increase button 42c and the decrease button 42d from the time point when this step (S253) is completed.

[0142] Next, the user confirms the operation information J indicating that the main body 10 of the device is operating via the display unit 44 (S153), and then presses the increase button 42c or the decrease button 42d. At this time, the user can press the increase button 42c or the decrease button 42d twice consecutively (S104-2). Furthermore, the operation steps after this step (S104-2) are the same as... Figure 9 The steps described are common, so the explanation is omitted.

[0143] The main control unit 30 completes the startup of the main body 10 of the device (S353). At this time, the main control unit 30 sends an operation information J indicating that the startup of the main body 10 of the device has been completed to the remote controller 40. When the remote controller 40 receives the operation information J indicating that the startup of the main body 10 of the device has been completed, the control unit 50 causes the display unit 44 to display the oxygen supply quantity VQ (S254). In the remote controller 40 of this embodiment, the control unit 50 changes the display of the display unit 44 from the "operating" indicator light to the display of the oxygen supply quantity VQ. In the remote controller 40 of this embodiment, the user can change the setting value VS (by pressing the increase button 42c and the decrease button 42d) before the oxygen supply quantity VQ is displayed on the display unit 44.

[0144] When this operation is performed, the control unit 50 allows the increase button 42c or decrease button 42d to be operated before receiving operation information J, including the set value VS and oxygen supply amount VQ, from the device body 10. In this case, the control unit 50 does not receive information related to the set value VS stored in the main body storage unit 32. Therefore, in this case, the calculation unit 51 cannot update the set value VS based on the set value VS from the last operation. Therefore, in the remote controller 40 of this embodiment, when the increase button 42c or decrease button 42d is operated before the control unit 50 obtains operation information J from the device body 10, the control unit 50 updates the set value VS by adding or subtracting a reference amount VX from the initial value V0 stored in the storage unit 52. For example, when the increase button 42c is pressed before obtaining operation information J from the device body 10, the control unit 50 updates the set value VS by adding the reference amount VX to the initial value V0 without waiting for the operation information J from the device body 10 to arrive during the first operation of the increase button 42c. Alternatively, for example, if the decrement button 42d is pressed before the operation information J is obtained from the device body 10, the control unit 50 updates the set value VS by subtracting the reference amount VX from the initial value V0 during the first operation of the decrement button 42d without waiting for the operation information J from the device body 10 to arrive.

[0145] According to this operation procedure, when the user starts up the main unit 10, they can directly change the set value VS to the value they expect at the current time as soon as they hold the remote control 40. Therefore, this operation procedure can greatly reduce the operation waiting time of the remote control 40.

[0146] [Effects of the Implementation Method]

[0147] (1) The remote control 40 of this embodiment is a remote control for remotely operating the device main body 10. The remote control 40 includes a main body 41, operation buttons 42 provided on the main body 41, a communication unit 53 capable of communicating with the device main body 10, a control unit 50 for controlling the communication unit 53, and a first detection unit (accelerometer) 61 for detecting that the user is gripping the main body 41. When the accelerometer 61 detects that the user is gripping the main body 41, it outputs a first signal S1 to the control unit 50. When the first signal S1 is input, the control unit 50 establishes communication between the communication unit 53 and the device main body 10.

[0148] Thus, in the remote control 40 of this embodiment, the control unit 50, based on the detection result of the accelerometer 61, enables the communication unit 53 to establish communication with the device main body 10. Therefore, with the remote control 40 of this embodiment, communication between the remote control 40 and the device main body 10 can be established even without pressing the confirmation button, simply by the user holding the remote control 40. Therefore, the remote control 40 of this embodiment can reduce the number of times the user operates the remote control 40.

[0149] (2) The remote control 40 of this embodiment further includes: a cover 43, which is movable between a closed position P1 covering the operation button 42 and an open position P2 exposing the operation button 42; and a second detection unit 62 (magnetic sensor 62a), which detects that the cover 43 has moved to the closed position P1. In the remote control 40 of this embodiment, when the second detection unit 62 (magnetic sensor 62a) detects that the cover 43 has been moved to the closed position P1, the control unit 50 cuts off the input of the first signal S1 to the control unit 50.

[0150] In the remote control 40 with the above-described structure, the cover 43 of the remote control for the oxygen concentration device M, which is provided to prevent accidental operation, can be used to stop the function of the remote control 40 based on the detection result of the position (closed position P1 or open position P2) of the cover 43 by the second detection unit 62 (magnetic sensor 62a), thus eliminating the need for additional operation to stop the function of the remote control 40. Therefore, the remote control 40 according to this embodiment can stop the function of the remote control 40 without increasing the number of times the user operates the remote control 40. In addition, the remote control 40 according to this embodiment, in the structure where the first detection unit (accelerometer sensor) 61 is provided, can suppress the power consumption of the remote control 40.

[0151] (3) In the remote controller 40 of this embodiment, when the second detection unit 62 (magnetic sensor 62a) detects that the cover 43 has moved from the closed position P1, the control unit 50 allows the input of the first signal S1.

[0152] In the remote control 40 with the above-described structure, the communication unit 53 is enabled to communicate based on the detection result of the position of the cover 43 by the second detection unit 62 (magnetic sensor 62a), which is provided to prevent accidental operation. Therefore, the remote control 40 according to this embodiment enables the communication unit 53 to communicate without increasing the number of times the user operates the remote control 40.

[0153] (4) The remote controller 40 of this embodiment has a storage unit 52 that stores a set value VS of the oxygen supply amount VQ in the device body 10. The operation buttons 42 include an increase button 42c for increasing the set value VS and a decrease button 42d for decreasing the set value VS. In the remote controller 40 of this embodiment, for each operation of the increase button 42c, the control unit 50 updates the set value VS by adding a reference amount VX to it without waiting for the arrival of information related to the oxygen supply amount VQ from the device body 10 at the time of operation. And for each operation of the decrease button 42d, the control unit 50 updates the set value VS by subtracting the reference amount VX from it without waiting for the arrival of information related to the oxygen supply amount VQ from the device body 10 at the time of operation.

[0154] In conventional remote controls, when changing the oxygen supply setting, confirmation is required every time the setting is changed by one level, based on the information sent from the oxygen concentrator. In other words, conventional remote controls are designed to accept only the first change in a series of attempts, not subsequent changes. Therefore, changes to the oxygen supply setting result in significant waiting times.

[0155] In the remote control 40 of this embodiment, the control unit 50 updates the setting value VS without waiting for information from the device main body 10 each time the increase button 42c and the decrease button 42d are operated. Therefore, in the case where the increase button 42c and the decrease button 42d are operated multiple times consecutively, the control unit 50 can perform multiple previous setting value changes in one go. Therefore, the remote control 40 according to this embodiment can suppress the user's operation waiting time.

[0156] (5) In the remote controller 40 of this embodiment, the storage unit 52 also stores an initial value V0 related to the set value VS. In the remote controller 40 of this embodiment, if the control unit 50 operates the add button 42c or the decrement button 42d before obtaining the operation information J of the device main body 10 via the communication unit 53, when the add button 42c is operated for the first time, the control unit 50 updates the set value VS by adding a reference amount VX to the initial value V0 without waiting for the information related to the set value VS from the device main body 10 to arrive. And when the decrement button 42d is operated for the first time, the control unit 50 updates the set value VS by subtracting the reference amount VX from the initial value V0 without waiting for the information related to the set value VS from the device main body 10 to arrive.

[0157] In the remote controller 40 with the above-described structure, the control unit 50 can update the setting value VS based on the initial value V0 without waiting for information from the device main body 10. Therefore, the remote controller 40 according to this embodiment can perform the operation of changing the setting value VS before obtaining the current oxygen supply VQ of the device main body 10, thereby suppressing the waiting time for user operation.

[0158] (6) The remote controller 40 of this embodiment includes a display unit 44 for displaying a setting value VS. In the remote controller 40 of this embodiment, the control unit 50 updates the setting value VS displayed on the display unit 44 each time the setting value VS is updated.

[0159] In the remote control 40 with the above structure, the user can easily grasp the current oxygen supply VQ setting value VS by checking the display unit 44.

[0160] (7) In the remote controller 40 of this embodiment, the control unit 50 obtains the oxygen supply amount VQ via the communication unit 53 during the operation of the device main body 10. When the set value VS is different from the oxygen supply amount VQ, the set value VS is flashed on the display unit 44. When the set value VS is the same as the oxygen supply amount VQ, the set value VS is lit up on the display unit 44.

[0161] In the remote control 40 with the above-described structure, the user can easily confirm whether the current oxygen supply VQ matches the set value VS by checking the display unit 44. Furthermore, according to the remote control 40 with the above-described structure, the user can easily confirm that the oxygen supply VQ is changing by checking the flashing display of the set value VS.

[0162] (8) In the remote controller 40 of this embodiment, when the device body 10 is in operation, the control unit 50 obtains the operation information J of the device body 10 via the communication unit 53, and displays the oxygen supply amount VQ on the display unit 44 when the first signal S1 is input.

[0163] In the remote control 40 with the above structure, when the main body 10 of the device is in operation, the user can easily check the oxygen supply VQ simply by picking up the remote control 40.

[0164] The embodiments have been described above, but it should be understood that various changes in form and detail can be made without departing from the spirit and scope of the claims.
