Description

A medical device having a means for discharging the electric charge charged in the capacitor {APPARATUS FOR MEDICAL USE HAVING MEANS DISCHARGING CHARGES IN CAPACITOR}

The present disclosure relates to a medical device, and in particular, to a medical device having a means for discharging charge charged in a capacitor.

Medical devices for generating energy waves that can be used for medical purposes (for example, electromagnetic fields or extracorporeal shock waves) require a high voltage, so in general, medical devices are commercial electricity (for example, 220V household voltage electricity). Is used after converting to high voltage (for example, a voltage of 1500 to 2000V). For example, as can be seen in FIG. 1, energy storage elements (eg, capacitors) capable of charging and discharging electric charges may be used in medical devices to generate high-voltage electricity. Specifically, referring to FIG. 1, the medical device may receive power from the outside through a switched mode power supply (SMPS) that is a power supply device. In this case, the SMPS may charge the capacitor by post-processing the supplied power, and high-voltage electricity generated through the charge charged in the capacitor may be supplied to a component for generating a shock wave. Accordingly, the supplied high-pressure electricity is used to generate energy waves, and thus, the medical device can generate a shock wave of a desired intensity.

Energy storage elements such as capacitors for generating high-voltage electricity must be discharged after the operation of the medical device is finished. In general, the charge stored in the capacitor remains on the capacitor when the capacitor is opened. Some of the charges are discharged naturally, but the discharge through this method takes a relatively long time, and the charges are not completely removed, leading to a malfunction of the medical device. Since medical devices are used for humans, such a malfunction may lead to a very dangerous situation, such as applying a shock wave of unexpected intensity to a person.

Therefore, in general, conventional devices using a capacitor separately used a discharge circuit to discharge the charge stored in such a capacitor. However, this discharge circuit has disadvantages such as increasing the production cost of the product and increasing the volume of the product. Accordingly, there is a demand for a medical device having a means capable of discharging charges stored in a capacitor or the like without using a separate discharge circuit.

Hereinafter, each component will be described in detail.

According to some embodiments of the present disclosure, the power supply unit 1000 may receive power from the outside. In this case, the power supply unit 1000 may supply necessary power throughout the medical device. For example, the power supply unit 1000 may supply power to a display unit (not shown) for displaying an image in addition to the charge charging/discharging unit 200 and the control unit 400, and a cooling unit (not shown) for preventing overheating. have.

The power supply unit 1000 may include a switching mode power supply (SMPS). The SMPS may include a device for stabilizing power output by controlling an on-off time ratio of a semiconductor switch device. The SMPS may receive power (eg, 220V power for home) from an external battery and a commercial AC power source. In addition, the SMPS can convert the supplied power into stable power that can be used in each component of the medical device. The SMPS method may be a linear control method or a switch mode method, but is not limited thereto.

According to some embodiments of the present disclosure, the charge charging and discharging unit 200 may be connected to a power supply to receive power, and may charge or discharge electric charges. The charge charging/discharging unit 200 may be charged with electric charge when electric power is supplied. The charge charging/discharging unit may include elements suitable for storing electric charges. For example, the charge charging/discharging unit may include at least one capacitor. In this case, the charge charging/discharging unit may be composed of capacitors of an appropriate number or capacity to obtain a specific voltage (eg, a voltage of 1500 to 2000V). However, the present invention is not limited thereto, and the charge charging/discharging unit 200 may be configured in various ways.

The charge charging/discharging unit 200 may be connected to one or more components of the medical device 1000, and in this case, the charge charging/discharging unit may provide power of a specific voltage to the connected component. For example, the charge charging and discharging unit 200 may be connected to the impulse wave generating unit 300, in this case, the impulse wave generating unit 300 is operated by the power of the voltage converted by the charge charging and discharging unit 200 can do. However, the present invention is not limited thereto, and the charge charging/discharging unit 200 may be connected to various components.

According to some embodiments of the present disclosure, the impulse wave generator 300 is connected to the charge charging/discharging unit 200 to receive power, and may generate an impulse wave according to a first predetermined pattern. For example, as described above, the impulse wave generating unit 300 may be connected to the charge charging and discharging unit 200. In this case, the impulse wave generator 300 may operate on a voltage formed by electric charges stored in the charge charging/discharging unit 200.

According to some embodiments of the present disclosure, the medical device 1000 may be an Extracorporeal Wave Shock Therapy (EWST) device. In this case, the impulse wave generator 300 may generate an extracorporeal shock wave that can be used to treat a patient's affected area. The generated shock wave may be transmitted to the affected part of the patient through an impulse wave transmitting unit (not shown). The impulse wave generator 300 may be an electro hydraulic, electromagnetic, or piezoelectric element. When the medical device 1000 is an extracorporeal shock wave treatment device, the method that can be used for the impulse wave generator 300 is patent application number 10-2018-0008622 and patent application number 10- It is disclosed in 2017-0181152.

According to some embodiments of the present disclosure, the medical device 1000 may be a transcranial magnetic stimulation (TMS) device. In this case, the impulse wave generator 300 may generate an electromagnetic field that can be used to treat an affected part of a patient. The generated electromagnetic field may be transmitted to the affected area of the patient through the impulse wave transmitting unit. When the medical device 1000 is a transcranial magnetic stimulation device, the method that can be used for the impulse wave generating unit 300 is patent application number 10-2015-0107834 and patent application number 10, which are incorporated herein by reference. -It is disclosed in 2016-0011274.

The term “impulse wave” as used herein may refer to an energy wave for medical purposes generated in a medical device. For example, the impulse wave may refer to an electromagnetic field or an extracorporeal shock wave. However, the present invention is not limited thereto, and the impulse wave may include various energy waves that can be used for medical purposes.

According to some embodiments of the present disclosure, the impulse wave generator 300 may generate an impulse wave according to a first predetermined pattern. In this case, the first predetermined pattern may include an operation time for generating an impulse wave, a period, a number of times an impulse wave is generated, an intensity of an impulse wave, a pattern of change in intensity, and the like. For example, the impulse wave generator 300 may generate an impulse wave whose intensity changes in the form of a sine wave during one period in a period of 10 seconds for 20 minutes. However, the present invention is not limited thereto, and the first predetermined pattern may include various types of impulse wave generation patterns.

The first predetermined pattern may be generated or changed by the manufacturer of the medical device 1000. Further, the first predetermined pattern can be created or changed by the user. The first predetermined pattern may be stored in a storage medium (eg, a memory) of the medical device 1000. However, the present invention is not limited thereto, and the first predetermined pattern may be generated and stored according to various methods.

The controller 400 generally controls the overall operation of the medical device 1000. For example, the controller 400 may control components of the medical device 1000 according to a user's manipulation. In addition, the controller 400 may control connections between components of the medical device 1000. For example, the control unit 400 may control the power supply unit 100 and the charge charging/discharging unit 200 to be connected or disconnected from each other. In addition, the control unit 400 may control the charge charging/discharging unit 200 and the impulse wave generating unit 300 to be connected or disconnected from each other. Here, the connection between the components may include a physical or logical connection, and the connected components may transmit/receive information or transmit/receive power to each other. However, the present invention is not limited thereto, and the controller 400 may control various operations.

The control unit 400 may control the impulse wave generator 300 to operate by using the power stored in the charge charging and discharging unit 200 (ie, energy by stored electric charges) in order to discharge the charge charging and discharging unit 200. . For example, the control unit 400 is between the power supply unit 100 and the charge charging and discharging unit 200 at a first time point in order to cut off the power supply to the charge charging and discharging unit 200 based on a first predetermined pattern. Between the charge charging and discharging unit 200 and the impulse wave generating unit 300 after the first point in time to disconnect the connection and discharge the charge charging and discharging unit 200 by the first operation of the impulse wave generating unit 300 Can keep the connection.

In detail, the control unit 400 may recognize the end point of the first predetermined pattern at which the first predetermined pattern ends. In this case, the control unit 400 may disconnect the power supply unit 100 and the charge charging/discharging unit 200 so that the charge charging/discharging unit 200 is no longer charged. Here, a point in time at which the connection between the power supply unit 100 and the charge charge/discharge unit 200 is released so that the charge charge/discharge unit 200 is no longer charged may be referred to as a first point of time.

After the first point in time, the control unit 400 controls to maintain the connection between the charge charging and discharging unit 200, which is disconnected from the power supply unit 100, and the impulse wave generator 300 performing the first predetermined pattern. I can. In this case, the impulse wave generator 300 may perform the first operation by the electric charge stored in the charge charging/discharging unit 200 disconnected from the power supply unit 100. Here, the first operation includes various operations of the impulse wave generator 300 to discharge the charge charging/discharging unit 200 after the first point in time. For example, the first operation may include an operation following a first predetermined pattern (eg, an operation of maintaining the first predetermined pattern). Specifically, when the first predetermined pattern is composed of a pattern of a certain period (for example, after generating impulse waves 20 times for 0.5 seconds in a period of 1 second for 10 minutes, generation of impulse waves during the remaining 0.5 seconds operation) Stop), the first operation may include the impulse wave generator 300 performing a pattern of a period included in the first predetermined pattern after the first point in time. The impulse wave generator 300 terminates the operation when the charge charging/discharging unit 200 is discharged by the first operation. Accordingly, the charge charging/discharging unit 200 may be discharged by the first operation of the impulse wave generator 300 without a separate discharge circuit.

The first point of view may be variously determined based on the end point of the first predetermined pattern. For example, the first time point may include the same time point as the end time point of the first predetermined pattern. In this case, the first operation may follow the first predetermined pattern as described above. In addition, the first operation may be operated with a lower output than the first predetermined pattern (for example, an output of 20% of the average output of the first predetermined pattern) to remind the user that the operation for treatment is ended. May be.

Here, the output of the first predetermined pattern may be an output of the impulse wave generator 300 generated according to the first predetermined pattern. The output of the impulse wave generator 300 may be expressed as a numerical value representing a characteristic of the impulse wave generated by the impulse wave generator 300. For example, the output of the first predetermined pattern may be displayed by the intensity, amplitude, frequency, luminosity, temperature, etc. of the impulse wave, but is not limited thereto.

For example, as the output of the impulse wave generator 300 increases, the intensity of the impulse wave transmitted to the patient increases, and as the output of the impulse wave generator 300 decreases, the intensity of the impulse wave transmitted to the patient decreases. It is desirable to lose. In addition, when the medical device 1000 is a TMS device, the output of the impulse wave generator 300 may be displayed in units of'Tesla' for the magnetic field. In addition, as another example, when the medical device 1000 is an extracorporeal shock wave treatment device, the output of the impulse wave generator 300 may be displayed in units of'bar' for the extracorporeal shock wave. However, the present invention is not limited thereto, and the output of the impulse wave generator or the output of the first predetermined pattern may be expressed as a numerical value representing characteristics of various impulse waves.

As another example, the first time point may include a time point before the end time point of the first predetermined pattern. Specifically, for example, the first time point may include a time point 2 seconds before the end time point of the first predetermined pattern. When the first point in time is before the end point of the first predetermined pattern, the first point is the impulse wave generator 300 to charge the charge that is disconnected from the power supply unit 100 until the end point of the first predetermined pattern. It can be operated by the electric charge stored in the whole 200. In this case, the operation of the impulse wave generator 300 is preferably maintained in the same or similar (for example, within 10% of the error range) the residual pattern of the first predetermined pattern until the end of the first predetermined pattern. Do.

According to some embodiments of the present disclosure, the controller 400 acquires charge amount information about the amount of charge stored in the charge charging/discharging unit 200 from the charge amount measuring unit (not shown) after the first time point, and based on the charge amount information The connection between the charge charging/discharging unit 200 and the impulse wave generating unit 300 may be disconnected. The charge amount measuring unit may measure the capacity, voltage, current, etc. of the charge charging/discharging unit 200 or the capacity, voltage, current, etc. of the capacitor element included in the charge charging/discharging unit 200. The control unit 400 may obtain information about the amount of charge stored in the charge charging/discharging unit 200 based on the information measured by the amount measuring unit. The electric charge measurement unit may be configured using a method and apparatus known in the art.

The controller 400 may identify whether the charge charging/discharging unit 200 is discharged based on the amount of charge information. When the discharge of the charge charging and discharging unit 200 is completed, the control unit 400 may control to release a connection between the charge charging and discharging unit 200 and the impulse wave generating unit 300. Accordingly, the charge charging/discharging unit 200 may be used for the next operation of the medical device 1000 in a discharged state.

As described above, since the connection between the power supply unit 100 and the charge charging/discharging unit 200 is released at the first time point, the charge charging/discharging unit 200 cannot receive additional power after the first time point. Accordingly, the control unit 400 may have less output of the first operation compared to the first predetermined pattern due to the limited energy of the charge charging/discharging unit 200. For example, the output of the impulse wave generator 300 according to the first operation may be generated in an exponentially decreasing form. Here, the output of the first operation may mean the output of the impulse wave generator 300 according to the first operation. The output of this first operation may appear in various forms according to the design of the charge charging/discharging unit 200 and the impulse wave generating unit 300.

The medical device 1000 according to the present disclosure maintains the operation of the impulse wave generator 300 (ie, the first operation) when the operation for treatment is terminated (or should be terminated) without a separate discharge circuit. The charge charging/discharging unit 200 may be discharged.

3 to 5, the operation of the control unit when the first point in time is the end point of the first predetermined pattern will be described.

3, conventional medical devices discharge energy storage elements such as capacitors by terminating an operation for treatment (for example, an operation for generating an electromagnetic field or an extracorporeal shock wave) immediately at the end point of a pattern for treatment. Separately required components such as a discharge circuit for

On the other hand, the medical device 1000 according to the present disclosure includes a charge charging/discharging unit (eg, 2 seconds ago) at the end point (or before (eg, 2 seconds)) of a pattern for treatment (eg, a first predetermined pattern). Since the operation of the impulse wave generator 300 is maintained to discharge 200, the charge charging/discharging unit 200 of the medical device 1000 can be discharged without a separate discharge circuit.

4 to 5, the output of the impulse wave generator 300 is shown to explain the operation of the control unit 400 when the first point 510 is the end point of the first predetermined pattern.

Referring to FIG. 4, it is shown that the output of the impulse wave generator 300 is generated as a reference output three times in each period of a first predetermined pattern. Here, the reference output may include an average and a minimum value of the output of the impulse wave generator 300. The output of the first predetermined pattern shown in Fig. 4 is constant, and thus the reference output is shown as their average value. When the output of the impulse wave generator 300 changes in various ways (for example, when the first predetermined pattern includes a period in the form of a sinusoidal curve), the reference output is a variety of the average, minimum, or maximum values of the output values. Can be determined in a way.

According to some embodiments of the present disclosure, the controller 400 may control the first operation to at least partially follow the first predetermined pattern. Specifically, as described above, the first time point may be the end time point of the first predetermined pattern. In this case, the control unit 400 is between the power supply unit 100 and the charge charging and discharging unit 200 in order to cut off the power supply to the charge charging and discharging unit at a first time point 510 that is the same as the end time of the first predetermined pattern. You can block the connection. In addition, the control unit 400 maintains the connection between the charge charging and discharging unit 200 and the impulse wave generating unit 300 after the first point in time 510 so that the impulse wave generating unit 300 is connected to the charge charging and discharging unit 200. It is possible to control to perform the first operation through the stored electric charge. Referring to FIG. 4, it is shown that the impulse wave generator 300 generates the output three times per cycle as the same output as the reference output according to a first predetermined pattern after the first point in time. The first operation of the impulse wave generator 300 according to the first predetermined pattern may be performed until the charge charging/discharging unit 200 is discharged.

With reference to FIG. 4, the case where the first point of view is the end point of the first predetermined pattern has been described, but the content described with reference to FIG. 4 is also when the first point of view is different from the end point of the first predetermined pattern. Can be applied. For example, when the first point in time is before the end point of the first predetermined pattern, the controller 400 may control the first operation to at least partially follow the first predetermined pattern.

According to some embodiments of the present disclosure, the controller may control the first operation of the impulse wave generator so that the output of the first predetermined pattern becomes less than or equal to a first threshold after a first point in time. Referring to FIG. 5, it is shown that the output of the impulse wave generator 300 is generated as a reference output three times in each period of a first predetermined pattern. As described above, the reference output may include an average of the output of the impulse wave generator 300 and a minimum value. In addition, when the output of the impulse wave generator 300 changes in various ways (for example, when the first predetermined pattern includes a sinusoidal period), the reference output is the average, minimum, or maximum value of the output values. Etc. can be determined in various ways.

Referring to FIG. 5 in detail, as described above, the first point in time may be the end point of the first predetermined pattern. In this case, the control unit 400 is between the power supply unit 100 and the charge charging and discharging unit 200 in order to cut off the power supply to the charge charging and discharging unit at a first time point 510 that is the same as the end time of the first predetermined pattern. You can block the connection. In addition, the control unit 400 maintains the connection between the charge charging and discharging unit 200 and the impulse wave generating unit 300 after the first point in time 510 so that the impulse wave generating unit 300 is connected to the charge charging and discharging unit 200. It is possible to control to perform the first operation through the stored electric charge.

In this case, as can be seen in FIG. 5, the controller 400 may control the first operation so that the output of the first predetermined pattern after the first point in time becomes less than or equal to the first threshold value 520. The first threshold may be set to a value capable of recognizing that the operation for treatment of the medical device 1000 is being ended. For example, the first threshold 520 may be 20% of the reference output of the first predetermined pattern. This first threshold 520 may be determined or changed by a manufacturer or user of the medical device 1000. Referring to FIG. 5, after the first point in time, the impulse wave generator 300 outputs the impulse wave three times per cycle with an output equal to or less than the first threshold 520 (ie, the first operation). . The first operation of the impulse wave generator 300 may be performed until the charge charging/discharging unit 200 is discharged.

With reference to FIG. 5, the case where the first viewpoint is the end time of the first predetermined pattern has been described, but the content described with reference to FIG. 5 is also when the first viewpoint is different from the end time of the first predetermined pattern. Can be applied. For example, when the first point in time is before the end point of the first predetermined pattern, the controller 400 may control the first operation to be performed below the first threshold of the first predetermined pattern.

6 is a diagram for describing an operation of the medical apparatus 1000 in which a first point in time is before an end point of a first predetermined pattern according to some embodiments of the present disclosure.

According to some embodiments of the present disclosure, the first point in time may be before the end point of the first predetermined pattern. In this case, as described above, the controller 400 may control the first operation after the first point in time to at least partially follow the first predetermined pattern. As another example, when the first point in time is before the end point of the first predetermined pattern, the controller 400 may control the first operation after the first point in time to operate below the first threshold value of the first predetermined pattern. have. However, it is not limited thereto.

According to some embodiments of the present disclosure, when the first point in time is before the end point of the first predetermined pattern, and the power supply to the charge charging/discharging unit 200 is cut off, the first operation is performed. It is possible to determine or obtain residual operation time information in which the output of is within a first range of the output of the first predetermined pattern, and determine the first time point based on the remaining operation time information.

Referring to FIG. 6 in detail, when the first point in time is before the end point of the first predetermined pattern, the impulse wave generator 300 operates from the first point in time to the end point of the first predetermined pattern. It is preferable that one operation follows a first predetermined pattern. In other words, when the first point in time is before the end point of the first predetermined pattern, the operation for treatment of the medical device 1000 is prevented from being recognized by the user as being terminated before the end point of the first predetermined pattern. In order to do so, the first operation is performed to be the same as or similar to the remaining operation of the first predetermined pattern (for example, the impulse wave generator 300 operates at 90% to 100% of the output of the first predetermined pattern). Can be. Here, when the first point in time is before the end point of the first predetermined pattern, a period from the first point in time to the end point of the first predetermined pattern may be referred to as a residual operation time 530. Also, a ratio of the output of the impulse wave generator 300 that can be determined to be similar to the residual operation of the first predetermined pattern may be referred to as a first range. For example, the first range may be 90% or more of the output of the first predetermined pattern, and 100% or less of the output of the first predetermined pattern. However, the present invention is not limited thereto, and the first range may be determined in various ranges.

As described above, since the energy of the charge charging/discharging unit 200 after the first time point is limited, the remaining operation time information (ie, information on the remaining operation time 530) is similar to the first predetermined pattern in the first operation. Or, it is desirable that it is appropriately determined so as to operate in the same manner. For example, the control unit 400 may determine the remaining operation time information by comparing the amount of charge stored in the charge charging/discharging unit 200 and the power consumption of the impulse wave generator 300 according to the first predetermined pattern. For example, when the impulse wave generator 300 can operate in a range of 90% to 100% compared to the output of the first predetermined pattern for 3 seconds by the amount of charge stored in the charge charging/discharging unit 200 (i.e. When the first range is 90% to 100% of the output of the first predetermined pattern), the control unit 400 may determine the remaining operation time as 3 seconds. The determination of the remaining operation time may be performed through calculation or simulation. In addition, when the first point in time is the end point of the first predetermined pattern, the amount of charge stored in the charge charging and discharging unit 200 and the output of the impulse wave generating unit 300 may be stored as data, and the control unit 400 The remaining operation time information can be determined using the stored data. As another example, the control unit 400 may obtain residual operation time information determined by a manufacturer or a user according to the first predetermined pattern (for example, through reading the remaining operation time information stored in the memory or through a user input). . In addition, the controller 400 may obtain information on a first range determined by a manufacturer or a user according to the first predetermined pattern. However, the present invention is not limited thereto, and the remaining operation time information and the first range may be determined in various ways.

Referring to FIG. 6, it is shown that during the remaining operation time from the first point in time 510 to the end point of the first predetermined pattern, the first operation is performed with the same output as the first predetermined pattern. It is advantageous that the output of the first operation after the end point is less than that of the first predetermined pattern (eg, 20% or less of the output of the first predetermined pattern). In this case, the first operation may be performed according to the first predetermined pattern. In addition, as shown in FIG. 6, the output of the impulse wave generator 300 after the end point of the first predetermined pattern has a smaller output than the first predetermined pattern, and is higher than the first predetermined pattern. It can have an operation frequency.

According to the medical device 1000 of the present disclosure, the first operation of the impulse wave generator 300 is performed within the first range during the remaining operation time, so that the charge charging/discharging unit 200 after the end point of the first predetermined pattern is performed. The time for discharge of) can be effectively reduced.
