<Device overview>
FIG. 1 is a front view showing a configuration of an otolaryngology spray unit 1 according to an embodiment of the present invention. As shown in the figure, the otolaryngology spray unit 1 is composed of three (otolaryngology) spraying devices 10a to 10c, and enables spraying operation for three patients at the same time.

  Hereinafter, the structure is demonstrated about the spray apparatus 10 of 1 unit which named spraying apparatus 10a-10c generically. The spray device 10 is provided with a display unit 2 (2a to 2c) on the front surface, and from the right in the figure below the display unit 2, a stop switch 4 (4a to 4b), a start switch 3 (3a to 3c), and It has the joint part 7 (7a-7c).

  The display unit 2 includes seven light emitters L1 to L7, and each of the light emitters L1 to L7 can exhibit a light emission state such as lighting, blinking, and extinguishing with a predetermined light emission color under the control of a module control unit described later. .

  The start switch 3 can perform a start operation (predetermined start operation) by pressing, and can start the spraying operation by the spraying device 10 using this start operation as a trigger. The start switch 3 may employ a lighting type and may be turned on during the spraying operation.

  When the spraying operation is started, the spraying operation for the set time is performed. Specifically, a chemical mist is ejected to the pharynx and nasal cavity of a patient who is a user through a hose (not shown) connected to the joint portion 7 and a spraying portion mask.

  The stop switch 4 can be stopped by pressing (predetermined stop operation), and the stop operation can be continuously executed. Then, the spraying operation by the spray device 10 can be temporarily stopped by performing the stop operation continuously for the first determination time JT1 (about 0.5 seconds), and further, the first determination time JT1 longer than the first determination time JT1. The spraying operation can be completely stopped by performing a stop operation continuously for 2 determination time JT2 (about 1 second) or more.

  Note that “pause” means that the spraying operation can be resumed for the remaining time of the set time, and “complete stop” means that the remaining time of the set time is invalid and the spraying operation is completely terminated. Means.

  The stop switch 4 may be a lighting type and may be turned on during stop processing. In this case, it may be possible to identify the stop state by blinking at the time of temporary stop and by turning on at the time of complete stop.

  The joint portion 7 connects one end of a connection hose (not shown), and can inhale the chemical mist into the pharynx and nasal cavity of the patient during the spraying operation via a spray portion mask provided at the other end of the connection hose.

  The control / drive unit 6 (6a to 6c) is a part that controls and drives the spraying operation in response to a start operation on the start switch 3 and a stop operation on the stop switch 4.

  The main switch 5 is a switch for turning on / off the operation power of the otolaryngology spray unit 1 and supplies power to the spray devices 10a to 10c by a predetermined on operation, and supplies power to the spray devices 10a to 10c by an off operation. Shut off the supply.

<Control system>
FIG. 2 is a block diagram showing the configuration of the control / drive system of the otolaryngology spray unit 1A adopting the first control / drive system in the otolaryngology spray unit 1. As shown in FIG.

  As shown in the figure, power is supplied from the power supply unit 31 to the spraying apparatuses 10a to 10c. Hereinafter, the structure is demonstrated about the spray apparatus 10 of 1 unit which named spraying apparatus 10a-10c generically.

  The control / drive unit 6 includes a module control unit 11 (11a to 11c), a timer unit 12 (12a to 12c), a spray time setting unit 13 (13a to 13c), a compressor unit 14 (14a to 14c), and a three-way solenoid valve 15 ( 15a-15c) and the sprayer 16 (16a-16c).

  The module control unit 11 includes a programmable controller (PC) and the like, can detect a start operation on the start switch 3 and a stop operation on the stop switch 4, and can control the light emission states of the light emitters L1 to L7 of the display unit 2. It is.

  Further, the module control unit 11 controls the timer unit 12 such as time setting and activation so that the spray operation for the set time set by the spray time setting unit 13 is performed with the start operation on the start switch 3 as a trigger. The pressure air and the opening / closing operation of the three-way solenoid valve 15 by the compressor unit 14 are controlled, and a chemical mist is ejected from the sprayer 16. As the spray time setting unit 13, a plurality of setting time switches corresponding to a plurality of setting times can be considered.

  When the module control unit 11 detects that the stop operation for the stop switch 4 has continued for the first judgment time JT1 or longer, the module control unit 11 controls the stop of the timer unit 12, and controls the compressed air and the three-way solenoid valve 15 of the compressor unit 14. By controlling the opening and closing operation, stop control for temporary stop is performed in which the spraying operation is temporarily stopped and the spray of the chemical mist is temporarily stopped from the sprayer 16.

  Further, when the module control unit 11 detects that the stop operation on the stop switch 4 has continued for a second determination time JT2 longer than the first determination time JT1, the control of the timer unit 12 such as time setting (reset) is performed. To stop control for complete stop.

  In addition, after the temporary stop, the module control unit 11 uses the start operation for the start switch 3 as a trigger, and the spray operation for the remaining time obtained by subtracting the spray operation execution time until the stop control for the temporary stop from the set time. The timer unit 12 is controlled to set the time, start up, and the like, and the compressed air and the three-way solenoid valve 15 are controlled to open and close by the compressor unit 14, and the chemical mist is ejected from the sprayer 16 again.

  Since the otolaryngology spray unit 1A has a configuration in which the compressor unit 14 is provided in each spray device 10, the distance between the sprayer 16 and the compressor unit 14 is relatively short, so that the spray operation can be started smoothly. The compressor unit 14 and the sprayer 16 are preferably provided with a three-way solenoid valve 15 for releasing the exhaust.

  FIG. 3 is a block diagram showing the configuration of the control / drive system of the otolaryngology spray unit 1B adopting the second control / drive system in the otolaryngology spray unit 1. As shown in FIG.

  As shown in the figure, power is supplied from the power supply unit 32 to the spraying apparatuses 10a to 10c. Further, compressed air is supplied from the compressor unit 34 to the spraying devices 10a to 10c.

  Hereinafter, the structure is demonstrated about the spray apparatus 10 of 1 unit which named spraying apparatus 10a-10c generically.

  The control / drive unit 6 includes a module control unit 21 (21a to 21c), a timer unit 22 (22a to 22c), a spray time setting unit 23 (23a to 23c), a sprayer 25 (25a to 25c), and a solenoid valve 26 (26a to 26a). 26c).

  The module control unit 21 controls the time setting and activation of the timer unit 22 so that the spraying operation for the set time set by the spraying time setting unit 23 is performed using the start operation on the start switch 3 as a trigger, and the compressor By controlling the pressure air and the opening / closing operation of the electromagnetic valve 26 by the unit 34, the chemical mist is ejected from the sprayer 25. A plurality of switches corresponding to a plurality of set times can be considered as the spray time setting unit 23.

  When the module control unit 21 detects that the stop operation for the stop switch 4 has continued for the first judgment time JT1 or longer, the module control unit 21 controls the timer unit 22 to set time, stop, etc., and the compressed air and solenoid valve by the compressor unit 34 are controlled. 26 is controlled so as to temporarily stop the spraying operation and temporarily stop the spraying of the chemical mist from the sprayer 25.

  When the module control unit 21 detects that the stop operation on the stop switch 4 has continued for a second determination time JT2 longer than the first determination time JT1, the module control unit 21 completely stops the timer unit 22 such as time setting (reset). Stop control.

  In addition, after the temporary stop, the module control unit 21 uses the start operation on the start switch 3 as a trigger, and the spray operation for the remaining time obtained by subtracting the spray operation execution time from the set time until the stop control for the temporary stop is executed. The timer unit 22 is controlled to set the time, start up, and the like, and the compressor unit 34 controls the opening and closing operation of the pressurized air and the electromagnetic valve 26 so that the chemical mist is ejected from the sprayer 25 again.

  In the otolaryngology spray unit 1B, the compressor unit 34 is shared by the spray devices 10a to 10c. Therefore, when at least one of the spray devices 10a to 10c performs the spray operation, the compressor unit 34 is operated. When the compressed air is supplied and the spraying devices 10a to 10c are in a completely stopped state where the spraying operation is not performed, control such as stopping the operation of the compressor unit 34 is performed.

  Moreover, in the otolaryngology spray unit 1B, since the compressor part 34 is shared between the spray devices 10a to 10c, the distance between the sprayers 25a to 25c and the compressor part 34 becomes relatively long. By providing a general electromagnetic valve 26 between the nebulizers 25, sufficient processing can be performed.

<Operation flow>
FIG. 4 is a flowchart showing the operation content of each spray device 10 in the otolaryngology spray unit 1.

  The main difference between the otolaryngology spray unit 1A and the otolaryngology spray unit 1B is that the compressor units 14 and 34 are individually present or shared for each of the spray devices 10a to 10c. Since there is no substantial difference in the operation content, the otolaryngology spray unit 1A will be described as a representative. Therefore, a part of the otolaryngology spray unit 1B is only given reference numerals in parentheses.

  With reference to the figure, in step S1, the spray device 10 is turned on by turning on the main switch 5 of the otolaryngology spray unit 1A. Hereinafter, the operation contents of the spraying device 10 that collectively refers to the spraying devices 10a to 10c in the otolaryngology spraying unit 1A (1B) shown in FIG. 2 will be described.

  Then, in step S2, the setting time of the spraying operation is set for the spraying time setting unit 13 (23) of the spraying device 10. For example, when the spray time setting unit 13 includes a plurality of time setting switches corresponding to a plurality of set times, by selectively setting the time setting switch corresponding to a desired spray time to an on state, A desired spraying time is set as the set time. At this time, a lamp provided in association with the time setting switch in the on state may be turned on.

  Then, in step S3, a nurse or the like performs a start operation (predetermined start operation) by pressing the start switch 3 of the spray device 10, whereby the start switch is turned on. In step S4, module control by the spray device 10 is performed. The spraying operation under the control of the unit 11 (21) is started. The processes of steps S4 to S13 are executed under the control of the module control unit 11.

  After that, in step S5, when a first long press state in which a stop operation (predetermined stop operation) by pressing the stop switch 4 continues for the first determination time JT1 (about 0.5 seconds) or longer is detected (YES) ) Goes to step S8, and if the first long press state is not detected (NO), the process goes to step S6.

  In step S6 executed when the first long press state is not detected in step S5 (NO), the spraying operation is continued, and in the subsequent step S13, when the end of the set time is detected (YES), End spraying operation.

  On the other hand, if the set time has not ended in step S7, the process returns to step S5. Thereafter, steps S5 to S7 are repeated until YES is determined in step S5 or YES is determined in step S7.

  Therefore, even if the stop operation for the stop switch 4 is mistakenly performed, if the duration of the stop operation is less than the first determination time JT1, step S5 is always “NO”, so the spray operation is stopped. Never happen. For example, when the stop operation is caused by a child's mischief, it is substantially “0” that the stop operation of 0.5 seconds or more is continued from the past results. It can be avoided reliably that the spraying operation is stopped.

  On the other hand, in step S8, which is executed when the first long-pressed state is detected in step S5 (YES), the spraying operation is forcibly paused under the control of the module control unit 11. Control is executed.

  Thereafter, in step S9, the module control unit 11 stores the remaining time obtained by subtracting the spray operation execution time from the start of the spray operation in step S4 to the temporary stop in step S8 from the set time set in step S2.

  The remaining time may be stored in a memory (register) provided in the module control unit 11 or may be stored in an external storage unit (not shown). If the count function of the timer unit 12 can be temporarily stopped at the time of the temporary stop in step S8, the remaining time may be stored by setting the timer unit 12 to the temporary count stop state.

  In step S10, when a second long press state in which the stop operation on the stop switch 4 is continuously performed for the second determination time JT2 (about 1 second) or longer is detected (YES), the process proceeds to step S11. When the second long press state is not detected (NO), the process proceeds to step S12. That is, in step S10, when the stop operation on the stop switch 4 is continuously performed for the second determination time JT2 that exceeds the first determination time JT1. The process proceeds to step S11 to switch from the temporary stop state to the complete stop state.

  In step S11 executed when the second long press state is detected in step S10 (YES), the remaining time stored in step S9 is reset to “0”, and the spraying operation is terminated. That is, even if it is the first determination time JT1 or more, if the stop operation for the stop switch 4 is further continued for the second determination time JT2 or more, the remaining time is set to “0” and the spraying operation is completely stopped. .

  When the remaining time is stored in the memory (register) provided in the module control unit 11 or the external storage unit in step S9, the reset process in step S11 sets the remaining time stored in step S8 to “0”. Will be reset. In step S8, when the count function of the timer unit 12 is temporarily stopped at the time of the temporary stop of step S8, the reset process of step S11 resets the count value of the timer unit 12 unit to the initial value.

  On the other hand, if the second long-pressed state is not detected in step S10 (NO), in step S12, another start operation for the start switch 3 is awaited. In step S12, if a re-start operation is detected (YES), the process proceeds to step S13. If not detected (NO), the process returns to step S10. Thereafter, steps S10 and S12 are repeated until YES is determined in step S10 (shift to complete stop processing) or YES is determined in step S12 (shift to restart processing).

  Then, in step S13 executed when YES is determined in step S12, the spraying operation is restarted. At this time, the module control unit 11 performs resumption control in which the spraying operation is resumed using the remaining time stored in step S9 as a new set time instead of the set time set in step S2.

  That is, when the stop operation for the stop switch 4 is continuously performed within the range of the first determination time JT1 or more and less than the second determination time JT2, the temporary stop process is performed and the spray operation remains when the spray operation is resumed. Control is performed to perform the spraying operation with the time set as a new set time, and the process returns to step S5. Thereafter, steps S5 to S7 are repeated until YES is determined in step S5 or YES is determined in step S7.

  When the remaining time is stored in a memory (register) provided in the module control unit 11 or an external storage unit in step S9, the remaining time stored in step S8 is set to a new set time in step S13. Will be. In step S8, when the count function of the timer unit 12 is temporarily stopped at the time of suspension of step S8, the count is restarted from the time of suspension of the timer unit 12 in step S13.

  As described above, according to the spray device 10 in the otolaryngology spray unit 1 (1A, 1B) of the present embodiment, the stop control by the control unit (the module control unit 11, the timer unit 12, and the spray time setting unit 13) is performed. The spraying operation by the spraying operation execution unit (compressor unit 14 (34), solenoid valve 15 (26), sprayer 16 (25)) is stopped only when the stop operation for the stop switch 4 is continued for the first determination time JT1 or more. I am letting.

  For this reason, even when a patient who is a user of the spraying device 10 erroneously performs a stop operation on the stop switch 4 during the spraying operation, if the duration is the first determination time JT1, the spray being executed The operation can be continued without stopping.

  As a result, the spray device 10 according to the present embodiment can execute a stable spray operation without stopping if the duration is less than the first determination time JT1 even if the stop switch such as child mischief is malfunctioning. It has the effect of making it.

  Furthermore, when resuming the spraying operation after the suspension process, the control unit in the spraying device 10 sets the remaining time obtained by subtracting the spraying operation execution time until the suspension process from the set time set in step S2 to a new set time. As a result, the resumption control is executed to execute the spraying operation.

  As a result, even when the spraying operation is temporarily stopped by the stop switch 4, the spraying operation for the set time set in step S2 can be executed in total before and after the temporary stop, so that an appropriate execution time can be obtained for the user. A spraying action can be provided.

  Further, since the control unit has a reset function for resetting the remaining time to “0” when the stop operation is continued for a second determination time JT2 longer than the first determination time JT1, the set time The complete stop that forcibly terminates the spraying operation can also be performed.

<Control to display unit 2>
The module control unit 11 (21) in the control unit can perform display control for controlling the light emission state of the light emitters L1 to L7 of the display unit 2 with the content corresponding to the execution time of the spraying operation. For example, at the start of the spray operation in step S4, all the light emitters L1 to L7 are turned off, and the light emitters L1, L2,... At the start of, all the light emitters L1 to L7 are turned on (or blinked), and the spraying operation is performed according to the light emission state of the light emitters L1 to L7 by sequentially turning off the light emitters L1, L2,. The execution time can be visually recognized by the user.

  In addition, when the spraying operation is resumed in step S13, the elapsed time corresponding to the remaining time that has become the new set time is set so as to start from the display state of the light emitters L1 to L7 corresponding to the spraying operation execution time until the suspension process. In addition, it is desirable to control the light emission state in the light emitters L1 to L7. For example, when the spraying operation of step S4 is started, all the light emitters L1 to L7 are turned off, and when the light emitters L1, L2,. When the spraying operation is stopped, the lighting states of the light emitters L1 to L3 are maintained until the spraying operation is resumed in step S13, and the light emitters L4, L5,. Also good.

  At the time of executing the remaining time reset process in step S13, it is desirable to put the display unit 2 in an initial state (all the light emitters L1 to L7 are turned off). Further, when the pause in step S8 is executed, the display unit 2 is also in a paused state by changing the light emission contents of the light emitters L1 to L7 of the display unit 2 (by turning on the lighting state, changing the emission color, etc.). It is desirable that visual recognition is possible.

  Further, the time intervals between the light emitters L1 to L7 that are sequentially turned on (or blinked) and sequentially turned off can be equalized, or can be shortened or lengthened with time.

  Thus, by controlling the light emission states of the light emitters L1 to L7 of the display unit 2 by the module control unit 11, the user of the spray device 10 can visually easily refer to the light emission states of the light emitters L1 to L7. It is possible to understand the progress of the spraying operation.

<Installation of emergency stop switch 9>
Furthermore, an emergency stop switch 9 may be separately provided at the upper right of the front portion of the otolaryngology spray unit 1 as shown by the dotted line in FIG.

  The state of the emergency stop switch 9 is connected to the emergency stop switch 9 so that the module control unit 11 (21) can detect the state, and each module control unit 11 uses the emergency stop operation of the emergency stop switch 9 as a trigger. An emergency stop control for immediately stopping each spraying operation by the spraying operation executing unit is configured.

  Thus, by providing the emergency stop switch 9, by performing an emergency stop operation on the emergency stop switch 9, the spraying operation of the spray devices 10a to 10c can be quickly and forcibly terminated in an emergency or the like. There is an effect.

  The emergency stop switch 9 shown in FIG. 1 is shown as being provided on the front side for convenience of explanation, but it is actually desirable to provide it in a place where a user such as a patient cannot operate it by mistake. . Further, in FIG. 1, the emergency stop switch 9 is provided for the emergency stop of the entire spray devices 10 a to 10 c, but may be provided individually for each spray device 10 like the stop switch 4.

<Others>
In the present embodiment, the otolaryngology spray unit 1 (1A, 1B) including the three spray devices 10a to 10c is shown. However, the number of spray devices 10 provided in the otolaryngology spray unit 1 is shown. Is optional.

  In addition, when a long press operation that is continuously performed with respect to the start switch 3 is erroneously performed, the spray operation is continued regardless of whether or not the long press operation is performed after the spray operation is started, and after the set time has elapsed. The spraying operation may be terminated, and a prevention function may be provided so that the spraying operation is not started again even if the long press operation continues even after the set time has elapsed.

  In this embodiment, an example in which the start switch 3 and the stop switch 4 are individually provided has been described. However, a start / stop switch that can support the functions of the start switch 3 and the stop switch 4 with a single switch is provided. Anyway. In this case, a mode is conceivable in which the start / stop switch functions as a start switch in the initial stage and functions as a stop switch during the spraying operation after the start operation. At this time, it is desirable to adopt a mode in which the lighting color is changed depending on whether it functions as a start switch or a stop switch.
