That is, the control unit 4 sets the injection amount and the pulse Output time (t on ) data is stored in advance and the injection amount is set. If so, the output time (t on ) can be derived. The pulse output time is the time during which the pulse is output once with the amplitude described below. The larger the input amount is set, the longer the pulse output time (t on ) is set long, The more the input amount decreases, the longer the pulse output time (t on ) is set to be short.

[0074] Also, the injection depth is set to the first injection depth through the user interface 2. If the first injection depth is set, the control unit 4 controls the amplitude (V) of the pulse to a first amplitude (V). That is, the control unit 4 sets the injection depth and the pulse amplitude (V ) is stored in advance, and when the injection depth is set, The amplitude (V) suitable for the determined implantation depth can be derived. The width corresponds to the magnitude of the voltage. The deeper the implantation depth is set, the wider the amplitude of the pulse. The pulse amplitude is set to be smaller as the injection depth decreases. .

[0075] In the single shot mode, the drug is injected only once, and the drug injection rate is not adjusted. That is, when the single shot mode is set, the user interface 2 The selection unit that sets the value can be deactivated.

[0076] As described above, the user sets the single shot mode and selects the injection depth and the amount of the drug. If the injection depth and the injection amount are set, the control unit 4 controls the pulse The amplitude (V) of the pulse, the output time (t on ) respectively.

[0077] The pulse generator 6 generates a pulse having a first amplitude (V) and a first output time ( t on 1) generates a pulse, which is applied to the solenoid coil 30. .

[0078] Referring to FIG. 5, in the single-shot mode, the pulse is output once, and the first output Time (t on 1) and occurs as a waveform having the first amplitude (V1). I understand.

[0079] When the pulse is applied to the solenoid coil 30, the pulse output time (t o n ) adjusts the time during which the solenoid coil 30 generates magnetic force, and The time during which the magnetic body 90 collides with the piston 40 is adjusted.

[0080] The output time of the pulse (t on ) is increased, the more the moving magnetic body 90 and the piston The time of collision with the piston 40 becomes longer, and the time that the piston 40 moves forward becomes longer. The drug delivery time is increased, and the amount of drug delivered is increased. As the output time of the pulse increases, the amount of drug injected increases and the output time of the pulse decreases. The more the pulse output time is increased, the less the amount of the drug is injected. The user can adjust the amount of drug injected as desired.

[0081] Furthermore, the amplitude (V) of the pulse determines the magnetic force generated in the solenoid coil 30. The magnitude of the magnetic force is adjusted, and the forward speed of the moving magnetic body 90 is adjusted according to the magnitude of the magnetic force. As the amplitude of the pulse increases, the forward speed of the moving magnetic body 90 increases. The depth of injection of the drug increases. As the pulse amplitude decreases, the drug injection depth decreases. That is, by increasing or decreasing the amplitude of the pulse, the user can inject the desired amount of drug. The depth can be adjusted.

[0082] Meanwhile, FIG. 6 shows a needle-free injection system according to an embodiment of the present invention in which the injection mode is a four-shot mode. FIG. 10 is a diagram showing a first example of a pulse waveform when the first injection amount and the first injection rate are set. It is a surface.

[0083] Referring to FIG. 6, the user selects the injection mode through the user interface 2. The injection mode is set, the injection amount of the drug is set to a first injection amount, and the injection depth is set to It is explained that the first level is set and the injection rate is set to the first injection rate.

[0084] When setting the injection mode, the user also sets the number of injections. When setting the shooting mode, select one of the following: 2-shot mode, 3-shot mode, or 4-shot mode. Select and set. The following explains that the four-shot mode is set.

[0085] When the four-injection mode is set, the control unit 4 turns on the switch of the needleless syringe. When the switch is turned on, the number of pulses (N) to be output is set to 4. When the switch is turned on once, the pulse is output four times, so four pulses are injected with one switch operation. can be.

[0086] Furthermore, the injection amount is set to the first injection amount through the user interface 2. If so, the control unit 4 controls the pulse output time (t on ) as the first Force time (t on 1). That is, the control unit 4 sets the injection amount and the pulse Output time (t on ) data is stored in advance and the injection amount is set. If so, the output time (t on ) can be derived. The pulse output time (t on ) is the time it takes for the pulse to be output once with the amplitude described below. The larger the injection amount is set, the shorter the pulse output time (t on ) is set long can be.

[0087] Also, the injection depth is set to the first injection depth through the user interface 2. If the first injection depth is set, the control unit 4 controls the amplitude (V) of the pulse to a first amplitude (V). That is, the control unit 4 sets the injection depth and the pulse amplitude (V ) is stored in advance, and when the injection depth is set, The amplitude (V) suitable for the determined implantation depth can be derived. The width corresponds to the magnitude of the voltage. The deeper the implantation depth is set, the wider the amplitude of the pulse. The pulse amplitude is set to be smaller as the injection depth decreases. .

[0088] Also, the injection rate is set to the first injection rate through the user interface 2. If set, the control unit 4 sets the pulse period (T) according to the first injection rate. Here, the injection rate is the number of injections per second, so the pulse period (T) is , is set to the reciprocal of the injection rate. For example, if the injection rate is set to 10, The period (T) of the pulse can be set to 1 / 10.

[0089] The control unit 4 sets the period (T) of the pulse depending on the injection rate. The pulse is output for the remaining time excluding the pulse output time (ton) in the pulse period (T). Output off time (t off ) where the pulse output off time (t off ) is the first output off time (t off 1) was set.

[0090] When the injection rate is set, the control unit 4 controls the pump 10 to control the pump 10 suitable for the set injection rate. The period (T) of the pulse can be derived, where the injection rate is the frequency, i.e. , the number of injections or injections per second, so the shorter the pulse period, the more pulses are generated. After the first pulse is released, the next pulse is delivered more quickly, increasing the number of shots per second. Therefore, the faster the injection rate is set, the shorter the pulse period. The slower the injection rate is set, the longer the pulse period is adjusted. At this time, when the pulse period (T) is adjusted according to the injection speed, The output time of the pulse (t on ) changes depending on the injection amount, The pulse period (T) is the pulse output time (t on ) is the remaining time excluding the pulse Output off time (t off ) is adjusted.

[0091] As described above, the user sets the injection mode, and controls the injection depth and the amount of the drug. When the injection amount and the injection rate of the drug are set, the control unit 4 controls the injection depth, The amplitude (V) of the pulse and the output time (t on ) and the output off time of the pulse (t off ) respectively.

[0092] The pulse generator 6 outputs the pulses at the number of times, period, and pulses set by the control unit 4. The amplitude (V) of the pulse, the output time (t on ) and the output off time of the pulse (t of f ) generates a pulse, which is applied to the solenoid coil 30. .

[0093] Referring to FIG. 6, in the four-times injection mode, the pulse is output four times. are output during the first output time (t off It can be seen that the waveform is not output during 1) and is generated with the first amplitude (V1).

[0094] When the pulse is applied to the solenoid coil 30, the pulse is output for a certain period of time. The time during which the solenoid coil 30 generates a magnetic force is adjusted, and the moving magnetic body 90 However, the impact time when the ball collides with the piston 40 is adjusted.

[0095] The output time of the pulse (t on ) is increased, the more the moving magnetic body 90 and the piston The time of collision with the piston 40 becomes longer, and the time that the piston 40 moves forward becomes longer. The drug delivery time is increased, and the amount of drug delivered is increased. As the output time of the pulse increases, the amount of drug injected increases and the output time of the pulse decreases. The more the pulse output time is increased, the less the amount of the drug is injected. The user can adjust the amount of drug injected as desired.

[0096] Furthermore, the amplitude (V) of the pulse determines the magnetic force generated in the solenoid coil 30. The magnitude of the magnetic force is adjusted, and the forward speed of the moving magnetic body 90 is adjusted according to the magnitude of the magnetic force. As the amplitude of the pulse increases, the forward speed of the moving magnetic body 90 increases. The depth of injection of the drug increases. As the pulse amplitude decreases, the drug injection depth decreases. That is, by increasing or decreasing the amplitude of the pulse, the user can inject the desired amount of drug. The depth can be adjusted.

[0097] Meanwhile, FIG. 7 shows a needleless injection system according to an embodiment of the present invention in which the injection mode is a four-shot mode. This shows another example of the pulse waveform when the second injection volume and first injection rate are set. This is a drawing.

[0098] Referring to FIG. 7, the user selects the injection mode through the user interface 2. The injection amount of the drug is set to a second injection mode, which is larger than the first injection amount. In addition, the injection depth is set to the first level, and the injection rate is set to the second level. The rate was set to the first injection rate.

[0099] When the four-injection mode is set, the control unit 4 turns on the switch of the needleless syringe. When the switch is turned on, the number of pulses output is set to four. When it is turned on once, the pulse is output four times, so four pulses are injected with one switch operation.

[0100] Furthermore, the injection amount can be set through the user interface 2 to be larger than the first injection amount. If the second injection amount is set to a larger amount, the control unit 4 controls the output of pulses according to the second injection amount. Time (t on ) at the second output time (t on 2). The second injection amount is set to the same as the first injection amount. Since the input amount is larger than the output time of the pulse (t on ) is the first output time (t on The second output time (t on 2). That is, the control section 4 is the injection amount and the pulse output time (t on ) data on the relationship between Once the injection amount is set, the output time (t o n The larger the injection amount is set, the faster the pulse output time becomes. The time is set to be long.

[0101] Also, the injection depth is set to the first injection depth through the user interface 2. If the first injection depth is set, the control unit 4 controls the amplitude (V) of the pulse to a first amplitude (V). That is, the control unit 4 sets the injection depth and the pulse amplitude (V ) is stored in advance, and when the injection depth is set, An amplitude (V) appropriate for the specified injection depth can be derived.

[0102] Also, the injection rate is set to the first injection rate through the user interface 2. If set, the control unit 4 sets the pulse period (T) according to the first injection rate. Determine.

[0103] The control unit 4 sets the period (T) of the pulse depending on the injection rate. The pulse output time (t on ) and the remaining time excluding Output off time (t off )

[0104] Therefore, the output off time of the pulse (t off ) during the period (T) of the pulse The second output time of the pulse (t on 2) is the remaining time excluding the second output off time ( t off 2). off 2) is the above 1st output off time (t off 2) is shorter than the first injection amount. If the second injection amount is set to be larger than on ) is the first Output time (t on The second output time (t on2) is set, but Since the input speed is the same and the period (T) of the pulse is the same, the period (T) of the pulse The second output time (ton2) is subtracted, and the remaining time is the second output off time (t off 2) is the output off time of the pulse (t off )

[0105] When the injection rate is set, the control unit 4 controls the pump 10 to control the pump 10 suitable for the set injection rate. The period (T) of the pulse can be derived, where the injection rate is the frequency, i.e. , the number of injections or injections per second, so the shorter the pulse period, the more pulses are generated. After the first pulse is released, the next pulse is delivered more quickly, increasing the number of shots per second. Therefore, the faster the injection rate is set, the shorter the pulse period. The slower the injection rate is set, the longer the pulse period is adjusted. At this time, when the pulse period (T) is adjusted according to the injection speed, The output time of the pulse (t on ) changes depending on the injection amount, The pulse period (T) is the pulse output time (t on ) is the remaining time excluding Output off time (t off ) is adjusted.

[0106] As described above, the user sets the four-injection mode, and adjusts the injection depth of the drug. When the injection amount of the drug and the injection rate of the drug are respectively set, the control unit 4 controls the injection depth. The amplitude (V) of the pulse and the output time of the pulse are determined by the injection amount and the injection speed. (t on ) and the output off time of the pulse (t off ) respectively.

[0107] The pulse generator 6 outputs the pulses at the number of times set by the control unit 4, and the amplitude of the pulses. (V), the output time of the pulse (t on ) and the output off time of the pulse (t off ) This generates a pulse, which is applied to the solenoid coil 30.

[0108] When the pulse is applied to the solenoid coil 30, the pulse is output for a certain period of time. The time during which the solenoid coil 30 generates a magnetic force is adjusted, and the moving magnetic body 90 The impact time at which the piston 40 is impacted is adjusted.

[0109] The output time of the pulse (t on ) is increased, the more the moving magnetic body 90 and the piston The time of collision with the piston 40 becomes longer, and the time that the piston 40 moves forward becomes longer. The drug delivery time is increased, and the amount of drug delivered is increased. As the output time of the pulse increases, the amount of drug injected increases and the output time of the pulse decreases. The more the pulse output time is increased, the less the amount of the drug is injected. The user can adjust the amount of drug injected as desired.

[0110] Furthermore, the amplitude (V) of the pulse determines the magnetic force generated in the solenoid coil 30. The magnitude of the magnetic force is adjusted, and the forward speed of the moving magnetic body 90 is adjusted according to the magnitude of the magnetic force. As the amplitude of the pulse increases, the forward speed of the moving magnetic body 90 increases. The depth of injection of the drug increases. As the pulse amplitude decreases, the drug injection depth decreases. That is, by increasing or decreasing the amplitude of the pulse, the user can inject the desired amount of drug. The depth can be adjusted.

[0111] Referring to FIG. 7, in the four-times injection mode, the pulse is output four times. are the second output times (t on2 2), and the first output off time ( t off It can be seen that the waveform is not output during 1) and is generated with the first amplitude (V1).

[0112] The second output time (ton1) is longer than the first output time (ton2). (t on 2), the output time of the pulse (t on ) increases and The collision time between the moving magnetic body 90 and the piston 40 becomes longer, and the piston 40 moves forward. Since the time of movement is longer, the ejection time of the drug is longer, and the injection amount of the drug increases. Therefore, the drug can be injected in a second injection amount that is greater than the first injection amount. Cut.

[0113] Meanwhile, FIG. 8 shows a needleless injection system according to an embodiment of the present invention in which the injection mode is a four-shot mode. This shows another third example of the pulse waveform when the first injection volume and second injection rate are set. This is a drawing.

[0114] Referring to FIG. 8, the user selects the injection mode through the user interface 2. The injection rate of the drug is set to a second rate higher than the first rate. the injection amount of the drug is set to the first injection amount, and the injection depth is set to the first level. This will be explained as an example.

[0115] When the four-injection mode is set, the control unit 4 turns on the switch of the needleless syringe. When the switch is turned on, the number of pulses (N) to be output is set to 4. When the switch is turned on once, the pulse is output four times, so four pulses are injected with one switch operation. can be.

[0116] Furthermore, the injection amount is set to the first injection amount through the user interface 2. If so, the control unit 4 controls the pulse output time (t on ) as the first Force time (t on 1). That is, the control unit 4 sets the injection amount and the pulse Output time (t on ) data is stored in advance and the injection amount is set. If so, the output time (t on ) can be derived.

[0117] Also, the injection depth is set to the first injection depth through the user interface 2. If the first injection depth is set, the control unit 4 controls the amplitude (V) of the pulse to a first amplitude (V). That is, the control unit 4 sets the injection depth and the pulse amplitude (V ) is stored in advance, and when the injection depth is set, It is possible to derive an amplitude (V) suitable for the set injection depth. The larger the pulse width, the larger the amplitude of the pulse is set.

[0118] Furthermore, the user can change the injection rate through the user interface 2 to a rate higher than the first injection rate. If the second injection rate is set to a faster rate, the control unit 4 controls the Set the pulse period (T').

[0119] The control unit 4 has data on the relationship between the injection rate and the pulse period (T). Once the injection rate is set, the injection rate suitable for the set injection rate is The period (T) of the pulse can be derived, where the injection rate is expressed as the number of oscillations per second. That is, the number of injections per second, so the shorter the pulse period, the more pulses are output. After the next pulse is delivered, the number of shots per second increases, increasing the injection rate. Therefore, the faster the injection rate is set, the shorter the pulse period becomes. The slower the injection rate is set, the longer the pulse period is adjusted. .

[0120] Since the injection rate is set to a second injection rate that is higher than the first injection rate, The pulse period is set to a period (T') shorter than the period (T) at the first injection rate. can be.

[0121] The control unit 4 controls the first output time (t on 1) excluded The remaining time, the third output off time (t off 3). The third output off time ( t off 3) is the first output off time (t off This is a shorter time than 1).

[0122] 6 and 8, the injection amount is the same as the first injection amount, and the pulse Output time (t on ) is the first output time (t on 1) The same or different injection rates are different from each other, the third output off time (t off 3) is the first output off time (t off It is set shorter than 1).

[0123] If the pulse output off time is shorter, the next pulse will come sooner after the pulse is output. As the injection rate increases, the number of injections per second increases. The faster the injection rate is set, the shorter the pulse period becomes. The pulse period is adjusted to be longer as the injection rate is increased. The more the pulse output off time (t off ) is set short, and the injection rate The slower the output off time of the pulse (t off ) is set to long.

[0124] As described above, the user sets the four-injection mode, and adjusts the injection depth of the drug. When the injection amount of the drug and the injection rate of the drug are respectively set, the control unit 4 controls the injection depth. The amplitude (V) of the pulse and the output time of the pulse are determined by the injection amount and the injection speed. (t on ) and the output off time of the pulse (t off ) respectively.

[0125] The pulse generator 6 outputs the pulses at the number of times set by the control unit 4, and the amplitude of the pulses. (V), the output time of the pulse (t on ) and the output off time of the pulse (t off ) This generates a pulse, which is applied to the solenoid coil 30.

[0126] Referring to FIG. 7, in the four-times injection mode, the pulse is output four times. are the first output times (t on 1), and the third output off time (t off 3), it is not output during this period, but occurs in the waveform of the first amplitude (V1).

[0127] The period (T') of the pulse is shortened, and the output off time of the pulse is shortened to the first output off time. Time (t off The second output off time (t off 3) It must be set to This shortens the time during which the pulse is not output, reducing the output interval between pulses. The number of injections per second of the drug increases, and the injection rate of the drug increases. The drug can be infused at a second, faster infusion rate.

[0128] Meanwhile, referring to Figs. 6 to 8, the injection amount and injection rate of the drug in the injection mode are Although the pulse to be adjusted is described as an example, it is not limited to this and can also be applied to the continuous shooting mode. is.

[0129] On the other hand, in the above embodiment, the nozzle opening / closing valve 50 is provided. However, the present invention is not limited to this, and the nozzle portion opening / closing valve 50 may be omitted. If 50 is not present, the drug container 22 is pre-filled with a drug.

[0130] In the above embodiment, the drug pressurizing section that pressurizes the drug in the drug storage section is a piston. 40, and the driving unit that drives the drug pressurizing unit includes a solenoid coil 30. This was explained as an example.

[0131] However, the present invention is not limited to this, and the drug pressurizing part may be any other member such as an elastic membrane in addition to the piston 40. Anything that can compress the drug can be used.

[0132] The driving unit applies pressure to the drug pressurizing unit such as the piston and the elastic membrane. When pulsed by the pulse generator, Any device that generates a driving force in a pulsed manner can be used.

[0133] For example, the driving unit may be a pneumatic actuator, a hydraulic actuator, a piezo actuator, or the like. The actuator may include a motor, a spring device, etc.

[0134] The driving unit may also include a laser beam. It is also possible to irradiate the drug directly by placing the laser beam in a separate sealed pressure chamber. The working fluid is irradiated with the radiation to generate bubbles, and the bubbles generated in the working fluid The volume expansion stretches the elastic membrane, applying instantaneous pressure to the drug in the drug storage portion. It may be configured.

[0135] In addition, the driving unit includes an electrode, and when high voltage electricity is discharged to the electrode, a separate tight A spark and dielectric breakdown occur in the working fluid in a closed pressure chamber, generating bubbles. The volume expansion caused by bubbles generated in the working fluid stretches the elastic membrane, The device may be configured to apply momentary pressure to the drug within the container.

[0136] The present invention has been described with reference to the embodiments illustrated in the drawings, which are given by way of example only. However, it is understood that those skilled in the art will recognize that various modifications and equivalent embodiments are possible. Therefore, the true technical scope of protection of the present invention is as follows: It must be determined by technical considerations. [Industrial Applicability]
