Description

Technical Field

[0001] This application relates to the technical field of medical devices, and particularly to a defibrillation device. Background Art

[0002] A typical defibrillator consists of a main unit and external electrode pads. The external electrode pads are connected to the main unit via a cable. When not in use, the electrode pads are fixed in the electrode holders of the main unit and are taken out when needed. The release of defibrillation energy is achieved through the external electrode pads, which are crucial for realizing the treatment function.

[0003] The defibrillator can confirm whether the external electrode pads are missing and whether the discharge function is normal through self-check. However, when the electrode pads are lost or not correctly placed in the holder, there is a risk that the defibrillation energy is released to the human body through the exposed metal of the electrode pads, causing electric shock injury. Therefore, it is necessary to confirm that the external electrode pads are in the electrode holders before self-check.

[0004] When using a microswitch to achieve the in-place detection of the electrode pads, it depends on the electrical and mechanical reliability of the microswitch itself. When the defibrillator is in use, it is easily affected by environmental factors such as impact vibration and liquid ingress, resulting in premature failure of the microswitch and low reliability. Summary of the Invention

[0005] Based on this, this application provides a defibrillation device that can accurately detect whether the electrodes of the defibrillation device are in the electrode holders.

[0006] In a first aspect, an embodiment of this application provides a defibrillation device, which includes:

[0007] A main unit, which includes a housing and a circuit board inside the housing;

[0008] An electrode assembly, which is connected to the circuit board and is used to release the defibrillation signal of the circuit board;

[0009] An electrode holder, which is arranged on the housing and includes an electrode placement position for placing the electrode assembly. The electrode placement position is provided with a conductive part connected to the circuit board. When the electrode assembly is placed in the electrode placement position, the conductive part of the electrode assembly is connected to the conductive part;

[0010] The circuit board is used to output a first electrical signal to the conductive part, detect a second electrical signal on the electrode assembly, and determine whether the electrode assembly is placed in the electrode placement position according to the detection result.

[0011] An embodiment of the present application provides a defibrillation device. By providing a conductive part connecting to a circuit board on an electrode base of the defibrillation device, when an electrode assembly of the defibrillation device is placed at an electrode placement position on the electrode base, a conductive part of the electrode assembly is connected to the conductive part, and by outputting a first electrical signal from the circuit board, detecting a second electrical signal on the electrode assembly, and determining whether the electrode assembly is placed at the electrode placement position according to the detection result, it is possible to accurately detect whether the electrode of the defibrillation device is in the electrode base, and the reliability is relatively high.

Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments.

[0020] The flowcharts shown in the accompanying drawings are only illustrative and do not necessarily include all the contents and operations / steps, nor do they necessarily need to be executed in the described order. For example, some operations / steps can be decomposed, combined, or partially merged, so the actual execution order may change according to the actual situation.

[0021] Next, some embodiments of the present application will be described in detail in conjunction with the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0022] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of a defibrillation device 100 provided by an embodiment of the present application.

[0023] As Figure 1 shown, the defibrillation device 100 includes a main unit 110, an electrode assembly 120, and an electrode base 130.

[0024] Exemplarily, the electrode assembly 120 includes an external electrode plate 121 and a cable 122. One end of the cable 122 is connected to the external electrode plate 121, and the other end is connected to the main unit 110.

[0025] For example, one end of the cable 122 is fixedly connected or detachably connected to the external electrode plate 121. When detachably connected, it is convenient to replace different external electrode plates 121. For example, an external electrode plate 121 for adults or an external electrode plate 121 for children can be connected.

[0026] For example, the other end of the cable 122 is fixedly connected or detachably connected to the main unit 110. When detachably connected, it is convenient to replace the electrode assembly 120 or separate the electrode assembly 120 from the main unit 110.

[0027] Among them, as Figure 1 and Figure 2 shown, the main unit 110 includes a housing 111 and a circuit board 10 inside the housing 111. The electrode assembly 120 is connected to the circuit board 10 and is used to release the defibrillation signal of the circuit board 10.

[0028] Exemplarily, a defibrillation component is provided on the circuit board 10. The defibrillation component can discharge to the patient's body through the electrode assembly 120, thereby realizing discharge treatment for the patient. For example, it can eliminate abnormal heart rhythms or rescue patients with sudden cardiac death.

[0029] Exemplarily, a monitoring component is provided on the circuit board 10. The monitoring component can monitor the patient's vital signs, such as electrocardiogram, blood oxygen, non-invasive blood pressure, etc. According to the patient's vital signs, the defibrillation component can be controlled to discharge to the patient's body through the electrode assembly 120 at an appropriate time, achieving a better effect.

[0030] Specifically, the electrode base 130 is provided on the housing 111. For example, the electrode base 130 can be provided on the upper side, left side, right side, front side or rear side of the housing 111. As Figure 1 shown, the electrode base 130 is provided on the upper side of the housing 111.

[0031] As Figure 3 shown, the electrode base 130 includes an electrode placement position 131 for placing the electrode assembly 120. As Figures 1 to 3 shown is a schematic diagram when the electrode assembly 120 is placed in the electrode placement position 131 (in position) of the electrode base 130.

[0032] Exemplarily, the electrode placement position 131 of the electrode base 130 can adopt various structures capable of realizing detachable fixed connection, such as snap-fastening structures, threaded locking structures, interference fit structures, magnetic attraction structures, adhesive structures, etc., so that the external electrode plate 121 of the electrode assembly 120 can be stably placed in the electrode placement position 131. Of course, the external electrode plate 121 can also be placed in the electrode placement position 131 of the electrode base 130 under the action of gravity and / or friction.

[0033] Specifically, as Figure 2 and Figure 3 shown, the electrode placement position 131 is provided with a conductive part 20 connected to the circuit board 10. When the electrode assembly 120 is placed in the electrode placement position 131, the conductive part of the electrode assembly 120 is connected to the conductive part 20.

[0034] Exemplarily, the conductive part 20 can include a metal conductive part 20, such as an iron sheet, a copper sheet, etc.

[0035] Exemplarily, the conductive part 20 can include a metal elastic sheet, which can better connect the conductive part of the electrode assembly 120 to the conductive part 20 when the electrode assembly 120 is placed in the electrode placement position 131 of the electrode base 130.

[0036] Exemplarily, the conductive part of the electrode assembly 120 can include, for example, the exposed part of the external electrode sheet.

[0037] Exemplarily, when the electrode assembly 120 is placed in the electrode placement position 131, the contact area between the conductive part of the electrode assembly 120 and the conductive part 20 can be less than, equal to or greater than the area of the conductive part 20. It can be understood that the area of the conductive part 20 can be not limited.

[0038] Specifically, as Figure 2 and Figure 3 shown, the circuit board 10 is configured to output a first electrical signal to the conductive part 20 located at the electrode placement position 131. The circuit board 10 is also configured to detect the second electrical signal on the electrode assembly 120 and determine whether the electrode assembly 120 is placed at the electrode placement position 131 according to the detection result.

[0039] In some embodiments, the first electrical signal includes at least one of the following: square wave, sine wave, triangular wave, sawtooth wave, variable PWM wave, custom waveform.

[0040] Exemplarily, the first electrical signal may include a signal with a fixed period waveform and / or a signal with a variable period waveform.

[0041] Exemplarily, if the second electrical signal on the electrode assembly 120 detected by the circuit board 10 includes a waveform signal identical to the first electrical signal, it can be determined that the electrode assembly 120 has been placed at the electrode placement position 131; if the second electrical signal on the electrode assembly 120 detected by the circuit board 10 does not include a waveform signal identical to the first electrical signal, it can be determined that the electrode assembly 120 has not been placed at the electrode placement position 131.

[0042] It can be understood that when the electrode assembly 120 is placed at the electrode placement position 131, the conductive part of the electrode assembly 120 is connected to the conductive part 20, and the first electrical signal output by the circuit board 10 to the conductive part 20 can be transmitted to the circuit board 10 of the host 110 through the conductive part of the electrode assembly 120. When the electrode assembly 120 is not placed at the electrode placement position 131, the conductive part of the electrode assembly 120 is not connected to the conductive part 20, and the first electrical signal output by the circuit board 10 to the conductive part 20 cannot be transmitted to the circuit board 10 of the host 110 through the electrode assembly 120. Therefore, it can be determined whether the electrode assembly 120 is placed at the electrode placement position 131 according to the second electrical signal on the electrode assembly 120.

[0043] Exemplarily, the circuit board 10 includes a signal generation circuit. The signal generation circuit is connected to the conductive part 20 and outputs a first electrical signal to the conductive part 20, such as outputting at least one of a square wave, a sine wave, a triangular wave, a sawtooth wave, a variable PWM wave, and a custom waveform. For example, the signal generation circuit may include a sine wave generation circuit and / or a triangular wave generation circuit, etc.

[0044] Exemplarily, as Figure 4 shown, the circuit board 10 includes a processor 11. The processor 11 is connected to the conductive part 20 and outputs a first electrical signal to the conductive part 20.

[0045] For example, the processor 11 can output a first electrical signal, such as a sine wave, through pins, such as general-purpose input / output (GPIO) pins.

[0046] For example, the processor 11 can output a first electrical signal, such as a sine wave or a square wave, etc., through an internal digital-to-analog conversion (DAC) circuit or an external digital-to-analog conversion circuit, such as a digital-to-analog conversion chip.

[0047] Exemplarily, as Figure 4 As shown, the circuit board 10 includes a first signal processing circuit 12, and the first signal processing circuit 12 is connected between the processor 11 and the conductive part 20 for processing the first electrical signal output by the processor 11.

[0048] Exemplarily, as Figure 4 As shown, the first signal processing circuit 12 may include at least one of a high-voltage suppression circuit 101, a coupling circuit 102, and a current-limiting circuit 103.

[0049] Exemplarily, the high-voltage suppression circuit 101 includes, for example, a diode, a gas discharge tube, etc. The coupling circuit 102 includes a capacitor and / or a filtering circuit, which can block direct current and pass alternating current to facilitate the passage of the first electrical signal. The current-limiting circuit 103 includes a resistor, which can limit the current of the first electrical signal to a lower level.

[0050] Exemplarily, the voltage withstand capacity of the first signal processing circuit 12 is not lower than the voltage withstand threshold, and the voltage withstand threshold is 80 - 100 volts. For example, when the defibrillator 100 performs self-check, a higher voltage is output to the electrode assembly 120, and the stronger voltage withstand capacity of the first signal processing circuit 12 can prevent the higher voltage from damaging the defibrillator 100 during self-check.

[0051] In some embodiments, the circuit board 10 is used to determine whether the electrode assembly 120 is placed at the electrode placement position 131 according to the signal characteristics of the second electrical signal and the signal characteristics of the first electrical signal.

[0052] Exemplarily, the signal characteristics may include at least one of the frequency, duty cycle, and voltage amplitude of the electrical signal.

[0053] Exemplarily, the circuit board 10 is used to output a first electrical signal with a preset frequency, a preset duty cycle, and / or a preset voltage amplitude. For example, the processor 11 can output a first electrical signal with a preset frequency, a preset duty cycle, and / or a preset voltage amplitude according to the signal characteristics of the first electrical signal stored in advance.

[0054] Exemplarily, the signal characteristics of the first electrical signal can be pre-stored. When detecting the second electrical signal on the detection electrode assembly 120, the signal characteristics of the second electrical signal are detected. When the detected signal characteristics are the same as or similar to the pre-stored signal characteristics of the first electrical signal, it can be determined that the electrode assembly 120 is placed at the electrode placement position 131.

[0055] Exemplarily, the circuit board 10 determines that the electrode assembly 120 has been placed at the electrode placement position 131 when the frequency of the second electrical signal is the same as the preset frequency, the duty cycle of the second electrical signal is the same as the preset duty cycle, and / or the voltage amplitude of the second electrical signal is the same as the preset voltage amplitude.

[0056] In some embodiments, the processor 11 of the circuit board 10 can detect the second electrical signal through an internal analog-to-digital conversion (ADC) circuit or an external analog-to-digital conversion circuit, such as an analog-to-digital conversion chip. For example, after the second electrical signal is collected by the analog-to-digital conversion circuit, the digital signal is transmitted to the processor 11 for analysis to obtain the signal characteristics of the second electrical signal.

[0057] In some embodiments, as Figure 4 shown, the circuit board 10 includes a second signal processing circuit 13. The second signal processing circuit 13 is connected between the electrode assembly 120 and the processor 11 and is used to process the second electrical signal on the electrode assembly 120 and then transmit it to the processor 11 on the circuit board 10.

[0058] Exemplarily, the second signal processing circuit 13 can include a signal conditioning circuit, for example, including at least one of a filtering circuit, an amplifying circuit, and a comparing circuit.

[0059] As an example, the circuit board 10 is used to output a first voltage signal in the form of a sine wave. The second signal processing circuit 13 converts the sine wave into a square wave and then transmits it to the processor 11 on the circuit board 10. The processor 11 determines that the electrode assembly 120 has been placed at the electrode placement position 131 when the frequency of the square wave is the same as the frequency of the sine wave.

[0060] In some embodiments, as Figures 1 to 4 shown, there are multiple electrode assemblies 120 and multiple electrode placement positions 131. The multiple electrode assemblies 120 can be respectively placed on one of the multiple electrode placement positions 131.

[0061] Exemplarily, there are two electrode assemblies 120. When defibrillating a patient, the two electrode assemblies 120 contact different positions of the patient's body. When a voltage is applied between the two electrode assemblies 120, an electric discharge can be performed on the patient's body.

[0062] Exemplarily, the external electrode plates 121 of the two electrode assemblies 120 can be respectively placed on one of the two electrode placement positions 131, as Figure 1As shown, the external electrode plate 121 of the left electrode assembly 120 can be placed at the left electrode placement position 131, and the external electrode plate 121 of the right electrode assembly 120 can be placed at the right electrode placement position 131.

[0063] Exemplarily, as Figure 4 shown, the circuit board 10 receives the second electrical signals on each electrode assembly 120, and determines whether the corresponding electrode assembly 120 is placed at one of the electrode placement positions 131 according to the signal characteristics of each second electrical signal.

[0064] For example, the circuit board 10 detects the second electrical signal on the left electrode assembly 120 and the second electrical signal on the right electrode assembly 120, and determines whether the external electrode plate 121 of the left electrode assembly 120 is placed at the left electrode placement position 131 according to the second electrical signal on the left electrode assembly 120, and determines whether the external electrode plate 121 of the right electrode assembly 120 is placed at the right electrode placement position 131 according to the second electrical signal on the right electrode assembly 120.

[0065] For example, the results of whether different electrode assemblies 120 are in place can be output respectively. Or, when it is determined according to the second electrical signal that the external electrode plates 121 of all electrode assemblies 120 have been placed at the corresponding electrode placement positions 131, the result that the electrode assemblies 120 are in place can be output. It can be understood that the processor 11 of the circuit board 10 can output the judgment result that the electrode plates are in place when multiple, such as two external electrode plates 121 are in place at the same time.

[0066] In some embodiments, as Figure 2 and Figure 4 shown, the conductive part 20 of at least one electrode placement position 131 is connected to the circuit board 10, and the conductive parts 20 of the remaining electrode placement positions 131 are connected to the conductive part 20 of at least one electrode placement position 131. Thus, by outputting the first electrical signal through one path, the first electrical signal output by the circuit board 10 can be transmitted to the conductive parts 20 of all electrode placement positions 131, which can simplify the structure and save the resources of the processor 11. The first electrical signals of each conductive part 20 are the same. Specifically, the signal characteristics of the first electrical signals of each conductive part 20 are the same.

[0067] Exemplarily, as Figure 4 shown, the conductive parts 20 of the remaining electrode placement positions 131 are connected to the conductive part 20 of at least one electrode placement position 131 through a resistor R. For example, when the defibrillator 100 performs self-check, a relatively high voltage is output to the electrode assembly 120, and this resistor R can limit the current flowing through the conductive part 20 and the electrode assembly 120 to a lower level. Of course, as Figure 2 shown, the conductive parts 20 of the remaining electrode placement positions 131 can also be directly connected to the conductive part 20 of at least one electrode placement position 131.

[0068] In some embodiments, the conductive parts 20 of the plurality of electrode placement positions 131 are each connected to the circuit board 10, and the circuit board 10 outputs a first electrical signal to the conductive parts 20 of each electrode placement position 131 simultaneously.

[0069] Exemplarily, one signal output terminal of the circuit board 10 is connected to the conductive parts 20 of the plurality of electrode placement positions 131, and a first electrical signal can be output to the conductive parts 20 of the plurality of electrode placement positions 131 simultaneously.

[0070] Exemplarily, as Figure 3 shown, a plurality of signal output terminals of the circuit board 10 are each connected to the conductive part 20 of one electrode placement position 131, and a first electrical signal can be output to the conductive parts 20 of the plurality of electrode placement positions 131 in parallel through the plurality of signal output terminals simultaneously.

[0071] In other embodiments, the conductive parts 20 of the plurality of electrode placement positions 131 are each connected to the circuit board 10, and the circuit board 10 outputs a first electrical signal to the conductive part 20 of each electrode placement position 131 respectively.

[0072] It can be understood that the first electrical signals output by the circuit board 10 to the conductive parts 20 of different electrode placement positions 131 can be the same or different. Specifically, the signal characteristics of the first electrical signals output by the circuit board 10 to the conductive parts 20 of different electrode placement positions 131 can be the same or different.

[0073] Exemplarily, when the first electrical signals output by the circuit board 10 to the conductive parts 20 of different electrode placement positions 131 are different, the circuit board 10 can be used to determine which electrode placement position 131 the electrode assembly 120 is placed on according to the detection result of the second electrical signal on the electrode assembly 120. For example, the circuit board 10 outputs a sine wave to the conductive part 20 of the left electrode placement position 131 and outputs a triangular wave to the conductive part 20 of the right electrode placement position 131; when it is detected that the waveform of the second electrical signal on one of the electrode assemblies 120 is a sine wave, it can be determined that the external electrode plate 121 of the electrode assembly 120 is placed on the left electrode placement position 131, and when it is detected that the waveform of the second electrical signal on one of the electrode assemblies 120 is a triangular wave, it can be determined that the external electrode plate 121 of the electrode assembly 120 is placed on the right electrode placement position 131.

[0074] The defibrillation device provided by the embodiment of the present application is configured such that a conductive portion connected to a circuit board is provided on an electrode base of the defibrillation device. When an electrode assembly of the defibrillation device is placed at an electrode placement position of the electrode base, a conductive portion of the electrode assembly is connected to the conductive portion. A first electrical signal is output from the circuit board to the conductive portion, a second electrical signal on the electrode assembly is detected, and based on the detection result, it is determined whether the electrode assembly is placed at the electrode placement position. This enables accurate detection of whether the electrodes of the defibrillation device are in the electrode base, and the reliability is relatively high.

[0075] It should be understood that the terms used in this application are merely for the purpose of describing specific embodiments and are not intended to limit the present application.

[0076] It should also be understood that the term "and / or" used in this application and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0077] The above are only specific embodiments of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
