Description

  The present invention relates to a signal generator capable of periodically outputting a signal.

Conventionally, signal generators that periodically output signals are known. For example, Patent Document 1 below discloses a metronome connected to a face mask. This metronome generates a repeated chest compression signal at a constant speed, and is activated or deactivated by operating an on / off slide switch.
JP-T-2004-509654

  However, once activated, the metronome described in Patent Document 1 does not stop until the on / off slide switch is switched off. Therefore, in order to stop the signal output from the metronome at a desired number of times, the user himself / herself continues to count the number of signal outputs, and when the signal is generated the desired number of times, The switch needs to be turned off. Therefore, the user may not be able to concentrate on the work when working based on the signal from the metronome.

  As an example, a case where a rescuer who intends to perform cardiopulmonary resuscitation uses the metronome described in Patent Document 1 is shown. In cardiopulmonary resuscitation, it is important that chest compressions and artificial respiration are alternately performed a predetermined number of times. However, since the metronome continues to output a signal unless the switch is switched, the rescuer must perform cardiopulmonary resuscitation while counting the number of times. Therefore, the burden on the rescuer is large.

  The present invention has been made to solve the above-described problems, and an object thereof is to provide a signal generator capable of outputting a signal periodically and a desired number of times.

  The signal generator of the present invention is a signal generator capable of periodically outputting a signal, a speed setting unit for setting the output speed of the signal, a number setting unit for setting the number of output of the signal, A generation unit that generates a signal at an output speed set by a speed setting unit at an output number set by the number setting unit, and an output unit that outputs a signal generated by the generation unit. .

  According to such a signal generator, a signal is generated at a set output speed (cycle) for a set number of times of output, and the generated signal is output each time. That is, signal generation and output are not performed more than the set number of outputs. Therefore, the signal can be output periodically and a desired number of times.

  In the signal generating device of the present invention, a maximum value setting unit for setting the maximum number of signal outputs based on the number of outputs set by the number setting unit, and a generation unit for repeatedly generating signals for the number of output times And an instruction unit for instructing the generation unit to generate a signal, and when the generation unit is instructed to generate a signal from the instruction unit, the total number of outputs by the output unit and the maximum set by the maximum value setting unit It is preferable to compare the output count and generate a signal when the total count is less than the maximum output count.

  In this case, when the output of the signal for the number of times of output is repeated, the total number of outputs already performed is compared with the maximum number of outputs set based on the number of outputs, and the total number of times is up to the maximum number of outputs. If not reached, a signal is generated and output. Thus, it is possible to repeatedly execute signal output for the set number of output times and to output a signal for a desired maximum number of output times.

  In the signal generator of the present invention, it is preferable that the maximum value setting unit sets a value obtained by multiplying the output number set by the number setting unit by a predetermined value as the maximum signal output number.

  In this case, the maximum number of outputs can be set simply by multiplying the set number of outputs by a predetermined value. That is, the setting of the maximum output count is simple.

  The signal generator of the present invention is preferably for assisting in the execution of cardiopulmonary resuscitation.

  In this case, the signal generator is used to assist in performing cardiopulmonary resuscitation. Therefore, those who perform cardiopulmonary resuscitation do not need to count the number of chest compressions themselves, and can concentrate on the cardiopulmonary resuscitation. The implementation of cardiopulmonary resuscitation includes not only the implementation of lifesaving treatment by cardiopulmonary resuscitation, but also the implementation of training for cardiopulmonary resuscitation.

  In the signal generator of the present invention, the output speed set by the speed setting unit is preferably 60 to 120 times / minute, and the number of outputs set by the number setting unit is preferably 15 to 40 times.

  In this case, the output speed (cycle) and the number of outputs recommended in the cardiopulmonary resuscitation can be set. Therefore, a person who performs cardiopulmonary resuscitation (a rescuer, a trainee, or the like) can perform cardiopulmonary resuscitation more appropriately by using this signal generator.

  The signal generation device of the present invention is for assisting the implementation of cardiopulmonary resuscitation, and is a signal generation device capable of periodically outputting a signal, wherein the output speed of the signal is 60 to 120 times / Speed setting unit set in the range of minutes, frequency setting unit for setting the number of signal outputs in the range of 15 to 40 times, and the maximum signal output value obtained by multiplying the number of outputs set by the frequency setting unit by 5 A maximum value setting unit that is set as the number of times, a generation unit that generates a signal for the number of times set by the number setting unit at an output speed set by the speed setting unit, and a signal that is generated by the generation unit An output unit and an instruction unit that instructs the generation unit to repeatedly generate signals for the number of times output by the generation unit, and when the generation unit is instructed to generate a signal by the instruction unit , Total output by the output unit And it compares the maximum output number of times set by the maximum value setting unit, the total number of times to generate a signal if it is less than the maximum number of outputs, characterized in that.

  According to such a signal generator, a signal is generated at a set output speed (cycle) for a set number of times of output, and the generated signal is output each time. That is, signal generation and output are not performed more than the set number of outputs. Therefore, the signal can be output periodically and a desired number of times. Thereby, the person (a rescuer, a trainer, etc.) who implements cardiopulmonary resuscitation can concentrate on implementation of cardiopulmonary resuscitation, without devoting effort in order to count the number of times. Further, this signal generator can repeatedly output signals for the number of outputs. In this case, the total number of outputs already performed is compared with the maximum output number set based on the output number, and a signal is generated and output when the total number does not reach the maximum output number. Therefore, it is possible to output a signal as many times as desired. Furthermore, in this signal generator, the output speed (cycle) and the number of outputs recommended in cardiopulmonary resuscitation can be set, and the maximum number of outputs recommended in cardiopulmonary resuscitation is set based on the number of outputs. The Therefore, a person who performs cardiopulmonary resuscitation (a rescuer, a trainee, or the like) can perform cardiopulmonary resuscitation more appropriately by using this signal generator.

  According to such a signal generator, a signal can be output periodically and a desired number of times.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the present embodiment, the signal generation device according to the present invention is applied to the rescue assisting device 10 for assisting the implementation of the cardiopulmonary resuscitation method. The rescue assisting device 10 can output a rhythm signal (output a signal periodically). In the description of the drawings, the same or equivalent elements are denoted by the same reference numerals, and redundant description is omitted.

  First, the structure of the rescue assistance apparatus 10 which concerns on embodiment is demonstrated using FIG. FIG. 1 is a perspective view showing an external appearance of the rescue assisting apparatus 10.

  The housing 11 of the rescue assisting device 10 is formed in a substantially rectangular parallelepiped having a height of 135 mm, a width of 70 mm, and a thickness of 24 mm. An operation unit 20 and a display unit 30 are provided on the front surface 12 of the housing 11. In addition, a plurality of small holes 15 are formed in the upper surface 13 of the housing 11 for passing a rhythm sound (a rhythm signal converted into a sound) from a speaker (not shown). In addition, the shape of the rescue assistance apparatus 10 is not limited to what is shown in FIG. For example, the rescue assisting device 10 may be further reduced in size to be of a card type (flat plate shape).

  The operation unit 20 includes a power button 21, a selection button 22, an adjustment button 23, and a start button 24.

  The power button 21 is a button for turning on or off the rescue auxiliary device 10. In addition, although the power supply of the rescue assistance apparatus 10 is a DC9V alkaline battery (not shown), the structure of a power supply is not limited to this. For example, a solar cell may be used as a power source.

  The selection button 22 is a button for switching the operation mode of the rescue assistant device 10. Each time the selection button 22 is pressed, the operation mode of the rescue assistance device 10 is periodically switched to a speed setting mode, an output count setting mode, a volume setting mode, and an output preparation mode.

  The adjustment button 23 can be operated when the rescue assisting device 10 is in one of the speed setting mode, the output count setting mode, and the volume setting mode. The adjustment button 23 increases or decreases the value corresponding to each setting mode. The values corresponding to the speed setting mode, the output count setting mode, and the volume setting mode are the output speed of the rhythm signal, the output count of the rhythm signal, and the volume of the rhythm sound, respectively.

  In the speed setting mode, when the adjustment button 23 is pressed, the output speed of the rhythm signal is set between 60 and 120 times / minute in increments of 5 times / minute. In the output count setting mode, the rhythm signal output count is set in increments of 5 between 15 and 40 by the same operation. In the volume setting mode, the volume of the rhythm sound is set to one of the high volume (2), the low volume (1), and the mute (0) by the same operation. The initial value of the output speed of the rhythm signal (the set value when the rescue assisting apparatus 10 is turned on) is 100 times / minute, and the initial value of the output number of the rhythm signal is 30 times. In the present embodiment, the rescue assistant device 10 is configured such that both the output speed and the output count of the rhythm signal are set in increments of 5, but there is no limitation on how much the value is increased or decreased. For example, the rescue assistance device 10 may be configured so that it can be set in increments of one. Also, the choice of volume is not limited to this embodiment.

  The setting range of the output speed and the number of output of the rhythm signal, and their initial values are set in consideration of the preferred implementation of cardiopulmonary resuscitation. In the implementation of cardiopulmonary resuscitation, it is important that a sufficient number of chest compressions are carried out continuously with sufficient strength. Therefore, it is recommended that the rescuer repeats a series of first-aid treatments 5 times, in which chest compression is performed 30 times at an output speed of 100 times / minute, and then artificial respiration is performed twice. During this time, the rescuer may use an automated external defibrillator (AED). The above initial values are set to assist the implementation of such a suitable cardiopulmonary resuscitation method. In addition, the above-described setting range is set so as to be able to deal with various rescue situations in consideration of individual differences (physique, medical conditions, etc.) of patients.

  The start button 24 is a button for periodically outputting a rhythm signal. When the start button 24 is pressed when the rescue assistant device 10 is shifted to the output preparation mode by the selection button 22, the rescue assistant device 10 is switched to the output mode, and the rhythm signal is set by the selection button 22 and the adjustment button 23. Is output according to the output speed and the output count. When the rhythm signal is output for the number of times of output, the rescue assisting device 10 switches from the output mode to the output preparation mode.

  The display unit 30 includes an LED unit 31 for displaying the operation mode of the rescue assistance device 10 and a number display unit 32 for displaying numbers. The LED unit 31 indicates an LED 31a indicating a speed setting mode, an LED 31b indicating an output number setting mode, an LED 31c indicating a volume setting mode, and an output preparation mode or an output mode. LED 31d is included.

  Each LED constituting the LED unit 31 is turned on, turned off, or blinked according to the operation mode of the rescue assistant device 10. Specifically, in the speed setting mode, the LED 31a is turned on and the other LEDs 31b to 31d are turned off. In the output count setting mode, the LED 31b is turned on, and the other LEDs 31a, 31c, and 31d are turned off. In the volume setting mode, the LED 31c is turned on and the other LEDs 31a, 31b, and 31d are turned off. In the output preparation mode, the LED 31d is turned on and the other LEDs 31a to 31c are turned off. In the output mode, the LED 31d blinks for the set number of outputs at the set output speed, and the other LEDs 31a to 31c are turned off.

  The number display unit 32 displays a value corresponding to the operation mode of the rescue assistance device 10. In the output preparation mode, it is preferable to display the number of times the rhythm signal is output, but the output speed of the rhythm signal or the volume (0 to 2) of the rhythm sound may be displayed.

  In the output mode, the numeric display unit 32 repeats an emergency treatment (hereinafter referred to as “one set of emergency treatment”) consisting of a predetermined number of chest compressions and a predetermined number of artificial respirations (hereinafter referred to as “number of sets”). And the actual number of outputs in the first-aid emergency treatment. Specifically, the digital display unit 32a corresponding to the hundreds in the number display unit 32 displays the number of sets, and the digital display unit 32b corresponding to the tenths and the digital display unit 32c corresponding to the first digit are emergency measures for one set. Displays the number of times the rhythm sound is output. In the operation mode, not the set number of outputs but the actual number of outputs in one set of emergency treatment is displayed. For example, the number display section 32 shown in FIG. 2 displays a number “215”, which indicates that the number of sets is “2” and the actual number of outputs is “15”.

  Next, the state transition of the rescue assistance apparatus 10 shown in FIG. 1 is demonstrated using FIG. FIG. 3 is a state transition diagram of the rescue assistance device 10. As described above, the rescue assistant device 10 is switched to any one of the speed setting mode, the output count setting mode, the volume setting mode, the output preparation mode, and the output mode. When the power of the rescue assistant device 10 is turned on, the operation mode of the rescue assistant device 10 is first set to the output preparation mode J04. Thereafter, each time the selection button 22 is pressed, the operation mode is periodically switched from the output preparation mode J04 to the speed setting mode J01, the output count setting mode J02, and the volume setting mode J03. When the start button 24 is pressed in the output preparation mode J04, the operation mode is switched to the output mode J05. Thereafter, when the output of the rhythm sound ends, the operation mode returns from the output mode J05 to the output preparation mode J04.

  Next, the functional configuration of the rescue assisting apparatus 10 shown in FIG. 1 will be described with reference to FIGS. FIG. 4 is a diagram showing a functional configuration of the rescue assisting apparatus 10, and FIG. 5 is a hardware configuration diagram of the rescue assisting apparatus 10.

  The rescue assisting apparatus 10 includes a speed setting unit 101, a number setting unit 102, a maximum value setting unit 103, an instruction unit 104, a generation unit 105, and an output unit 106 as functional components.

  As shown in FIG. 5, the rescue assisting device 10 includes an arithmetic device 201 including a plurality of integrated circuits (ICs), a storage device 202 including a memory, and the above buttons. The input interface 203 includes an output interface 204 that includes an LED, a digital display device, a speaker, and the like. In each function described with reference to FIG. 4, the arithmetic unit 201 receives an input signal from the input interface 203 and reads data stored in the storage unit 202, and performs a predetermined calculation based on the input signal and data. This is realized by outputting the signal generated by the calculation to the output interface 204.

  The speed setting unit 101 stores a plurality of rhythm signal output speed candidates in advance. The output speed stored by the speed setting unit 101 is between 60 and 120 times / minute, and is set in increments of 5 times / minute. In the speed setting mode, the speed setting unit 101 sets and stores one output speed from a plurality of candidates as the output speed of the output rhythm signal based on the signal from the adjustment button 23.

  The number setting unit 102 stores a plurality of candidates for the number of rhythm signal outputs in advance. The number of outputs stored by the number setting unit 102 is between 15 and 40, and is set in increments of 5. The number setting unit 102 sets and stores one output number from a plurality of candidates as the output number of the output rhythm signal based on the signal from the adjustment button 23 in the output number setting mode. At the same time, the output count is output to the maximum value setting unit 103. Note that the number of outputs set by the number setting unit 102 is the number of outputs in the emergency treatment for one set.

  The maximum value setting unit 103 stores the number of sets described above in advance. Here, the number of sets is preferably 5 based on the recommended cardiopulmonary resuscitation. The maximum value setting unit 103 sets and stores a value obtained by multiplying the number of outputs input from the number setting unit 102 by the set number “5” as the maximum number of output rhythm signals. That is, the maximum value setting unit 103 sets the maximum number of rhythm signal outputs based on the number of outputs set by the number setting unit 102. As described above, since the initial value of the rhythm signal output count is 30 times, the initial value of the maximum rhythm signal output count is 30 (times) × 5 (times) = 150 (times).

  The instruction unit 104 receives an instruction to generate a rhythm signal via the start button 24, generates an instruction signal for instructing generation of a rhythm signal when the start button 24 is pressed, and outputs the instruction signal to the generation unit 105. . That is, the instruction unit 104 instructs the generation unit 105 to generate a rhythm signal. This instruction can be repeated a plurality of times.

  Generation unit 105 generates a rhythm signal based on the instruction signal from instruction unit 104, and outputs the rhythm signal to output unit 106. The generation unit 105 generates the rhythm signal output speed, the number of rhythm signal outputs, and the maximum number of rhythm signal outputs from the speed setting unit 101, the number setting unit 102, and the maximum value setting unit 103 in order to generate a rhythm signal. Read each. The generation unit 105 stores the total number of rhythm signals generated so far (the rhythm sound output from the output unit 106).

  Then, the generation unit 105 compares the total number stored by itself with the read maximum output number. Here, when the total number of times is less than the maximum number of output times, the generation unit 105 generates a rhythm signal for the number of output times set by the number setting unit 102 at the output speed set by the speed setting unit 101, The rhythm signal is output to the output unit 106 every time it is generated. On the other hand, when the total number is equal to or greater than the maximum number of outputs, in other words, when the output of the rhythm signal for the set number of outputs is repeated a predetermined number of sets, the generation unit 105 does not generate a rhythm signal.

  The output unit 106 outputs the rhythm signal input from the generation unit 105 as a rhythm sound from a speaker (not shown), and outputs the rhythm signal as light from the LED 31d. Thereby, the user of the rescue assistance apparatus 10 can know the rhythm of chest compression suitable for implementation of the cardiopulmonary resuscitation.

  Next, the process of the rescue assistance apparatus 10 shown in FIG. 1 is demonstrated using FIG. FIG. 6 is a flowchart showing the processing of the rescue assistance device 10.

  First, the rhythm signal output speed is set by the speed setting unit 101, and the rhythm signal output frequency is set by the frequency setting unit 102 (step S01). Thereafter, the instruction unit 104 receives an instruction for outputting a rhythm signal (step S02). When the start button 24 is pressed at this time, a rhythm signal generation instruction is output from the instruction unit 104 to the generation unit 105, and the generation unit 105 generates a rhythm signal (step S03). The rhythm signal is generated based on the output speed set by the speed setting unit 101 and the number of outputs set by the number setting unit 102.

  Thereafter, the rhythm signal generated in this way is output by the output unit 106 (step S04). When the rhythm signal corresponding to the output count is output, the instruction unit 104 receives an instruction for outputting the rhythm signal again (step S05). When the start button 24 is pressed here, the generation unit 105 compares the total number of outputs up to that point with the maximum number of outputs (step S06). Here, when the total number of outputs is less than the maximum number of outputs (step S06; YES), the processes of steps S03 to S05 described above are repeated. On the other hand, when the total number of outputs is equal to or greater than the maximum number of outputs, that is, when the processes of steps S03 to S04 are repeated for a predetermined number of sets (step S06; NO), the process ends.

  As described above, according to the present embodiment, the rhythm signal is generated at the set output speed (cycle) by the set number of output times, and the generated rhythm signal is output each time. That is, the generation and output of the rhythm signal is not performed more than the set number of outputs. Therefore, a rhythm signal can be output periodically and a desired number of times. Thereby, the person (a rescuer, a trainer, etc.) who implements cardiopulmonary resuscitation can concentrate on implementation of cardiopulmonary resuscitation, without devoting effort in order to count the number of times.

  Further, according to the present embodiment, it is possible to repeatedly output signals for the number of times of output. In this case, the total number of outputs already performed is compared with the maximum number of outputs set based on the number of outputs, and if the total number does not reach the maximum number of outputs, a rhythm signal is generated and output. . Therefore, the rhythm signal can be output as many times as desired.

  Further, according to the present embodiment, a value obtained by multiplying the set output count by the predetermined value “5” is set as the maximum output count. Therefore, setting the maximum number of outputs is simple.

  In addition, according to the present embodiment, the output speed (cycle) and the number of outputs that are recommended in cardiopulmonary resuscitation can be set, and the maximum number of outputs that is recommended in cardiopulmonary resuscitation is set based on the number of outputs. Is done. Therefore, a person who performs cardiopulmonary resuscitation (a rescuer, a trainee, or the like) can perform cardiopulmonary resuscitation more appropriately by using the rescue assisting device 10.

  In the above, this invention was demonstrated in detail based on the embodiment. However, the present invention is not limited to the above embodiment. The present invention can be modified in various ways as described below without departing from the scope of the invention.

  In the said embodiment, although the signal generator which concerns on this invention was applied to the rescue assistance apparatus 10 for assisting implementation of a cardiopulmonary resuscitation, you may apply to other things. For example, the present invention may be applied to a metronome for assisting performance or a pacemaker for assisting exercise. In that case, the settable output speed, the number of output times, and the range of the maximum number of output times may be set to be suitable for the application.

  In the above embodiment, the maximum number of outputs is automatically calculated according to the set number of outputs. However, the signal generator may be configured so that the user can also input the maximum number of outputs. For example, the apparatus may be configured to directly input the maximum number of times of output, or the number of sets can be selected within a predetermined range (for example, 3 to 8 times, etc.) The apparatus may be configured to calculate the maximum number of outputs by multiplying.
