Description

Technical Field

[0001] This invention relates to the field of medical devices, and more particularly to power boards, defibrillators, and medical equipment. Background Technology

[0002] Existing medical equipment has many scattered components, making installation, modification, and replacement cumbersome. It is also bulky and presents many inconveniences during transportation, resulting in high manufacturing and transportation costs.

[0003] A defibrillator is a medical device primarily used to treat dangerous conditions such as ventricular fibrillation and atrial fibrillation. In clinical practice, depending on changes in the patient's condition, the defibrillator may need to be transferred with the patient between pre-hospital ambulances, in-hospital emergency departments, and other departments. Current defibrillators are relatively large, causing considerable inconvenience during transport. Summary of the Invention

[0004] In view of this, the present invention proposes a power board, a defibrillator, and a medical device.

[0005] A first aspect of the present invention provides a power supply board comprising:

[0006] The first PCB substrate includes a treatment parameter area, a power management area, a treatment charging area, and a treatment discharging area;

[0007] A treatment parameter circuit is located in the treatment parameter area, and the treatment parameter circuit is used to collect and analyze the patient's electrocardiogram signal and impedance signal;

[0008] A power management circuit is located in the power management area. The power management circuit is used for the management of system power-on / off, battery charging / discharging, and DC power conversion.

[0009] A treatment charging circuit is provided in the treatment charging area, and the treatment charging circuit is used to boost low-voltage DC power and store it in the energy storage capacitor of the defibrillator.

[0010] A therapeutic discharge circuit is provided in the therapeutic discharge area, and the therapeutic discharge circuit is used to release an impedance-adjusted defibrillation waveform according to the patient's physiological parameters;

[0011] Take a point on the first PCB substrate as the origin to establish the horizontal and vertical axes and divide it into four quadrants, wherein the treatment parameter circuit and the treatment charging circuit are located in two quadrants distributed on the diagonal.

[0012] A second aspect of the present invention provides a defibrillator, comprising a front shell, a rear shell, a main control board, and the aforementioned power board, wherein the front shell and the rear shell enclose a cavity, and the main control board and the power board are both disposed within the cavity, the main control board being mounted on the front shell, and the power board being mounted on the rear shell.

[0013] A third aspect of the present invention provides a medical device comprising a front shell, a rear shell, a main control board, and a power board, wherein the front shell and the rear shell enclose a cavity, the main control board and the power board are both disposed within the cavity, the main control board is mounted on the front shell, the power board is mounted on the rear shell, and the main control board and the power board are connected by a connecting wire.

[0014] As can be seen from the above technical solution, the power board proposed in the first aspect of this invention, by rationally arranging the positions of the treatment parameter circuit, power management circuit, treatment charging circuit, and treatment discharging circuit on the first PCB substrate, can effectively reduce the size of the power board, thereby miniaturizing the defibrillator and facilitating its transport. Furthermore, by positioning the treatment parameter circuit and treatment charging circuit in two diagonally opposite quadrants, maximizing the distance between the treatment parameter circuit and the treatment charging circuit, electromagnetic interference to the treatment parameter circuit during charging can be effectively reduced. This allows defibrillation charging to be initiated simultaneously with cardiac rhythm analysis, and discharging therapy can be performed immediately upon determining a shockable rhythm, saving clinical rescue time.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0027] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0028] like Figure 1-5 As shown, an embodiment of the present invention provides a defibrillator, which includes a front shell 10, a rear shell 20, a power board 30, and a main control board 40. The front shell 10 and the rear shell 20 enclose a cavity 101. The power board 30 and the main control board 40 are both disposed in the cavity 101. The power board 30 is installed in the rear shell 20, and the main control board 40 is installed in the front shell 10.

[0029] like Figure 6As shown, in some embodiments, the power board 30 includes a first PCB substrate 31, a treatment parameter circuit 32, a power management circuit 33, a treatment charging circuit 34, and a treatment discharging circuit 35. The first PCB substrate 31 includes a treatment parameter area 311, a power management area 312, a treatment charging area 313, and a treatment discharging area 314. The treatment parameter circuit 32 is located in the treatment parameter area 311 and is used to acquire and analyze the patient's electrocardiogram (ECG) signals and impedance signals. Specifically, the treatment parameter circuit 32 includes an ECG detection circuit and a small-signal impedance detection circuit, wherein the ECG detection circuit is used to acquire and analyze the patient's ECG signals, and the small-signal impedance detection circuit is used to acquire and analyze the patient's impedance signals. The power management circuit 33 is located in the power management area 312 and is used to manage system power on / off, battery charging / discharging, and DC-DC power conversion. Specifically, the power management circuit includes a power management minimum system, a battery management circuit, and a DC-DC conversion circuit, wherein the power management minimum system is used for system power on / off management, the battery management circuit is used for battery charging / discharging management, and the DC-DC conversion circuit is used for DC power conversion management. A treatment charging circuit 34 is located in the treatment charging area 313. The treatment charging circuit 34 is used to boost low-voltage DC power and store it in the defibrillator's energy storage capacitor. Specifically, the treatment charging circuit 34 includes a high-voltage charging circuit, which boosts low-voltage DC power and stores it in the defibrillator's energy storage capacitor. A treatment discharge circuit 35 is located in the treatment discharge area 314. The treatment discharge circuit 35 is used to generate a defibrillation waveform based on the patient's physiological parameters and impedance parameters detected by the treatment discharge circuit, and discharges according to the defibrillation waveform. Specifically, the treatment discharge circuit 35 includes a physiological parameter detection circuit and an impedance detection circuit. The physiological parameter detection circuit detects the patient's physiological parameters to determine whether the patient's physical condition is suitable for defibrillation. The impedance detection circuit detects the patient's impedance parameters. The treatment discharge circuit 35 generates a defibrillation waveform based on the impedance parameters and discharges according to the defibrillation waveform. A point on the first PCB substrate 31 is taken as the origin to establish a horizontal axis X and a vertical axis Y, dividing the area into four quadrants. The treatment parameter circuit 32 and the treatment charging circuit 34 are located in two quadrants distributed diagonally.

[0030] The four quadrants divided by the horizontal axis X and the vertical axis Y include the first quadrant S1 located in the upper right corner, the second quadrant S2 located in the upper left corner, the third quadrant S3 located in the lower left corner, and the fourth quadrant S4 located in the lower right corner. For example, the treatment discharge area 314 is located in the first quadrant S1, the treatment parameter area 311 is located in the second quadrant S2, the power management area 312 is located in the third quadrant S3, and the treatment charging area 313 is located in the fourth quadrant S4. Thus, the treatment parameter circuit 32 and the treatment charging circuit 34 are located in the second quadrant S2 and the fourth quadrant S4, respectively, on the diagonal, maximizing the distance between them. Of course, the treatment parameter circuit 32 and the treatment charging circuit 34 can also be located in the first quadrant S1 and the third quadrant S3, depending on the actual design requirements.

[0031] By adopting the above technical solution, and rationally arranging the positions of the treatment parameter circuit 32, power management circuit 33, treatment charging circuit 34, and treatment discharging circuit 35 on the first PCB substrate 31, the size of the power board 31 can be effectively reduced, making the defibrillator miniaturized and facilitating its transportation. Furthermore, by positioning the treatment parameter circuit 32 and treatment charging circuit 34 in two diagonally opposite quadrants, maximizing the distance between the treatment parameter circuit 32 and the treatment charging circuit 34, electromagnetic interference from the treatment charging circuit 34 to the treatment parameter circuit 32 during charging can be effectively reduced. This allows the defibrillator to simultaneously perform cardiac rhythm analysis and defibrillation charging, enabling immediate discharge therapy when the analysis result indicates a shockable rhythm, thus saving clinical rescue time.

[0032] In some embodiments, the treatment parameter area 311 is provided with a first isolation area 315 on the side near the horizontal axis X and the side near the vertical axis Y, and the creepage distance of the first isolation area 315 is greater than 3mm. This embodiment can isolate the treatment parameter circuit 32 from the power management circuit 33, the treatment charging circuit 34 and the treatment discharging circuit 35, thereby improving the safety of use.

[0033] In some embodiments, the power management area 312 is provided with a second isolation area 316 on the side near the horizontal axis X and the side near the vertical axis Y, and the creepage distance of the second isolation area 316 is greater than 5.3 mm. This embodiment can isolate the power management circuit 33 from the treatment charging circuit 34, the treatment discharging circuit 35 and the treatment parameter circuit 32, thereby improving the safety of use.

[0034] The second isolation zone 316 is set up alternately with the first isolation zone 315.

[0035] In some embodiments, the power board 30 further includes a first shielding cover 36 disposed in the treatment parameter area 311, and the treatment parameter circuit 32 is located inside the first shielding cover 36. By placing the treatment parameter circuit 32 inside the first shielding cover 36, not only can the interference of electromagnetic signals generated by circuit modules outside the first shielding cover 36 on electronic components inside the first shielding cover 36 be reduced, but the interference of electromagnetic signals generated by electronic components inside the first shielding cover 36 on other circuit modules outside the first shielding cover 36 can also be reduced, effectively solving the electromagnetic compatibility (EMC) problem in the system.

[0036] In some embodiments, the power board 30 further includes a second shielding cover 37 disposed in the power management area 312, and the power management circuit 33 is located inside the second shielding cover 37. By placing the power management circuit 33 inside the second shielding cover 37, not only can the electromagnetic signals generated by the circuit modules outside the second shielding cover 37 be reduced to interfere with the electronic components inside the second shielding cover 37, but the electromagnetic signals generated by the electronic components inside the second shielding cover 37 can also be reduced to interfere with other circuit modules outside the second shielding cover 37, effectively solving the electromagnetic compatibility (EMC) problem in the system.

[0037] It should be noted that the power management circuit 33 located in the power management area 312 is a low-power circuit and is susceptible to interference from other circuit modules, especially the treatment charging circuit 34. By adopting the above technical solution, firstly, the power management area 312 is also far away from the treatment charging area 313; secondly, a second isolation area 316 is provided between the power management area 312 and the treatment charging area 313; and thirdly, a second shielding cover 37 is provided in the power management area 312, and the power management circuit 33 is located inside the second shielding cover 37. This can effectively prevent the large signal generated by the treatment charging circuit 34 during use from interfering with the power management circuit 33, thus avoiding the situation where the defibrillation system unexpectedly loses power and restarts, delaying the rescue opportunity.

[0038] In some embodiments, the distance between the electronic components located in the treatment parameter area 311 and the electronic components located in the power management area 312 is not less than 6.3 mm. The distance between the electronic components in the treatment parameter area 311 and the electronic components in the power management area 312 needs to meet a voltage of 3000Vdc to ensure safe operation of the device. By setting the distance between the electronic components in the treatment parameter area 311 and the electronic components in the power management area 312 to not less than 6.3 mm, the aforementioned safety requirements can be met.

[0039] In some embodiments, the power board 30 further includes a DC power input interface 38 electrically connected to the treatment charging circuit 34. The DC power input interface 38 is located within the power management area 312 and is situated on the side of the power management area 312 closest to the treatment charging area 313. By placing the DC power input interface 38 on the side of the power management area 312 closest to the treatment charging area 313, the length of the connection line between the DC power input interface 38 and the treatment charging circuit 34 can be shortened, effectively solving the problem of low charging efficiency caused by line loss.

[0040] The main control board 40 includes a first PCB substrate 41, a main control circuit 42, and a parameter circuit 43, and may optionally include at least one of a button circuit 44 and an interface circuit 4. The first PCB substrate 41 includes a main control area 411 and a parameter area 412, and may optionally include at least one of a button area 413 and an interface area 414.

[0041] like Figure 7As shown, in some embodiments, the main control board 40 includes a second PCB substrate 41, a main control circuit 42, a parameter circuit 43, a button circuit 44, and an interface circuit 45. The second PCB substrate 41 includes a main control area 411, a parameter area 412, a button area 413, and an interface area 414. The main control circuit 42 is located in the main control area 411 and is used to receive operation button trigger signals and control the defibrillator to enter the corresponding working mode. Exemplarily, the operation buttons include a power button and a working mode button. The working mode button includes an AED mode button, a manual defibrillation mode button, a pacing mode button, and a monitoring mode button. The AED mode button, manual defibrillation mode button, pacing mode button, and monitoring mode button correspondingly trigger the defibrillator to enter the AED mode, manual defibrillation mode, pacing mode, and monitoring mode, respectively. In some embodiments, the main control circuit 42 is also used to control the transmission of audio and video signals of the defibrillator. The parameter circuit 43 is located in the parameter area 412 and is used to collect physiological parameters reflecting the patient's vital signs and / or monitor the patient. A button circuit 44 is located in the button area 413 and is used to electrically connect to the operation buttons. An interface circuit 45 is located in the interface area 414 and is used to electrically connect to the input / output interface. In some embodiments, the main control area includes a first side, a second side opposite to the first side, and a third side. The parameter area is located on the first side of the main control area, and the button area is located on the second side of the main control area and / or the interface area is located on the third side of the main control area. In some embodiments, the second side and the third side may be the same. In some embodiments, the main control area 411 includes a first side 411a and a second side 411b opposite to the first side 411a. The parameter area 412 is located on the first side 411a of the main control area 411, and the button area 413 and the interface area 414 are located on the second side 411b of the main control area 411. Placing the button area 413 and the interface area 414 in the main control area 411 can reduce costs, and the entire main control board can be replaced during maintenance.

[0042] By rationally arranging the relative positions of the main control circuit 42, parameter circuit 43, button circuit 44, and interface circuit 45 on the second PCB substrate 41, the size of the main control board 40 can be effectively reduced, making the defibrillator miniaturized and facilitating its transport. Furthermore, integrating the main control circuit 42, parameter circuit 43, button circuit 44, and interface circuit 45 onto the second PCB substrate 41 effectively reduces manufacturing and connection costs. In addition, by positioning the parameter area 412 on one side of the main control area 411 and the button area 413 and interface area 414 on the other side, electromagnetic interference to the parameter circuit 43 when the button circuit 44 and interface circuit 45 are triggered can be reduced, ensuring stable and normal operation of the device.

[0043] Of course, the main control circuit 42, parameter circuit 43, button circuit 44 and interface circuit 45 are not limited to being located on the second PCB substrate 41. The main control circuit 42, parameter circuit 43, button circuit 44 and interface circuit 45 can also be located individually or in combination on different PCB substrates. As long as the parameter area 412 is located on one side of the main control area 411, the button area 413 and the interface area 414 are located on the other side of the main control area 411, and the electromagnetic interference caused by the button area 413 and the interface area 414 when triggered is small, the device can operate stably and normally.

[0044] For example, there are two PCB substrates. The main control circuit 42, the button circuit 44, and the interface circuit 45 are located on one PCB substrate, and the parameter circuit 43 is located on the other PCB substrate; or, the button circuit 44 and the interface circuit 45 are located on one PCB substrate, and the main control circuit 42 and the parameter circuit 43 are located on the other PCB substrate; or, the button circuit 44 is located on one PCB substrate, and the main control circuit 42, the parameter circuit 43, and the interface circuit 45 are located on the other PCB substrate; or, the interface circuit 45 is located on one PCB substrate, and the main control circuit 42, the parameter circuit 43, and the button circuit 44 are located on the other PCB substrate.

[0045] For example, there are three PCB substrates. The main control circuit 42 is located on one PCB substrate, the button circuit 44 and the interface circuit 45 are located on one PCB substrate, and the parameter circuit 43 is located on the remaining PCB substrate; or, the main control circuit 42 and the parameter circuit 43 are located on one PCB substrate, the button circuit 44 is located on one PCB substrate, and the interface circuit 45 is located on the remaining PCB substrate; or, the main control circuit 42 and the button circuit 44 are located on one PCB substrate, the interface circuit 45 is located on one PCB substrate, and the parameter circuit 43 is located on the remaining PCB substrate; or, the main control circuit 42 and the interface circuit 45 are located on one PCB substrate, the button circuit 44 is located on one PCB substrate, and the parameter circuit 43 is located on the remaining PCB substrate.

[0046] For example, there are four PCB substrates, with the main control circuit 42, parameter circuit 43, button circuit 44, and interface circuit 45 respectively located on different PCB substrates.

[0047] Among them, the parameter circuit 43 includes functional detection circuits such as electrocardiogram (ECG), blood oxygen saturation (SPO2), non-invasive blood pressure (NIBP), body temperature (TEMP), and heart rate (HR).

[0048] In some embodiments, the distance between the electronic components located in the button area 413 and the electronic components located in the treatment parameter area 311 is not less than 6.3 mm. The distance between the electronic components in the treatment parameter area 311 and the electronic components in the button area 413 needs to meet a voltage of 3000Vdc to ensure safe operation of the device. By setting the distance between the electronic components in the treatment parameter area 311 and the electronic components in the button area 413 to be not less than 6.3 mm, the aforementioned safety requirements are met.

[0049] In some embodiments, a third isolation region 415 is provided between the main control region 411 and the parameter region 412, and the creepage distance of the third isolation region 415 is greater than 5.3 mm. This embodiment can isolate the parameter circuit 43 from the main control circuit 42, thereby improving safety.

[0050] In some embodiments, parameter area 412 includes a first parameter area 4121 and a second parameter area 4122, and parameter circuit 43 includes a first parameter circuit 431 and a second parameter circuit 432. The first parameter circuit 431 is disposed in the first parameter area 4121, and the second parameter circuit 432 is disposed in the second parameter area 4122. The first parameter circuit 431 includes one of an electrocardiogram (ECG) detection circuit and a blood oxygen saturation detection circuit, and the second parameter circuit 432 includes the other of an ECG detection circuit and a blood oxygen saturation detection circuit.

[0051] In some embodiments, a fourth isolation region 416 is provided between the first parameter region 4121 and the second parameter region 4122, and the creepage distance of the fourth isolation region 416 is greater than 5.3 mm. This embodiment can isolate the first parameter region 4121 and the second parameter region 4122, thereby improving safety in use.

[0052] like Figure 1-5 As shown in Figure 7, in some embodiments, the main control board 40 further includes an operation button 401, which is mounted on the second PCB substrate 41 and electrically connected to the button circuit 44. By directly mounting the operation button 401 on the second PCB substrate 41, not only can the connection cost and processing and testing cost between the operation button 401 and the second PCB substrate 41 be saved, but also the problem of functional failure caused by using other connection methods can be avoided. In particular, the problem of being unable to power on and unable to charge or discharge due to the failure of the operation button 401 can be effectively avoided. The operation button 401 includes a power button, a working mode button, a charging button, a discharging button, and an energy adjustment button, etc. Of course, the operation button 401 can also be directly mounted on the front cover 10, and the operation button 401 and the button circuit 44 can be connected by wires.

[0053] In some embodiments, the front housing 10 includes a panel 11, which has a display screen 111 and buttons 112. The main control board 40 is stacked on top of the panel 11. At least a portion of the buttons 112 are opposite to the button area 413, and at least a portion of the display screen 111 is opposite to the main control area 411 and the parameter area 412. The display screen 111 is electrically connected to the main control area 411. The button area 413 includes a first side 413a facing the panel 11 and a second side (not shown) facing away from the panel 11. An operation button 401 is located on the first side 413a of the button area 413 facing the panel 11. The operation button 401 is opposite to the buttons 112, so that pressing the buttons 112 triggers the operation button 401. With this embodiment, on the one hand, the space occupied by the main control board 40 in the area enclosed by the front housing 10 and the rear housing 20 can be effectively reduced, allowing the defibrillator to be miniaturized; on the other hand, the length of the connection cable between the display screen and the main control board can be reduced, avoiding EMC problems caused by long display screen wiring.

[0054] In some embodiments, the main control board 40 further includes an input / output interface 402, which is mounted on the second PCB substrate 41 and electrically connected to the interface circuit 45. By directly mounting the input / output interface 402 on the second PCB substrate 41, not only can the connection cost and processing and testing cost between the input / output interface 402 and the second PCB substrate 41 be saved, but also the problem of functional failure caused by using other connection methods can be avoided. The input / output interface 402 includes USB, RJ45, external sync defibrillator input port, and ECG analog output port, etc. Of course, the input / output interface 402 can also be directly mounted on the front cover 10, or connected to the interface circuit 45 via wires.

[0055] In some embodiments, the panel 11 includes a first side 11a and a second side 11b opposite to the first side 11a. The front cover 10 also includes a first side plate 12 disposed on the first side 11a of the panel 11. The first side plate 12 has a first opening 121, and the input / output interface 402 is opposite to the first opening 121. External terminals pass through the first opening 121 and are plugged into the input / output interface 402 to achieve electrical connection.

[0056] In some embodiments, the front cover 10 further includes a second side plate 13 disposed on the second side 11b of the panel 11. The second side plate 13 has at least one second opening 131. The main control board 40 further includes a parameter interface 403 mounted on the second PCB substrate 41, with the parameter interface 403 opposite to the second opening 131. By directly mounting the operation parameter interface 403 to the second PCB substrate 41, not only can the connection cost and processing and testing cost between the operation button 401 and the second PCB substrate 41 be saved, but also the problem of functional failure caused by using other connection methods can be avoided.

[0057] In some embodiments, parameter interface 403 includes a first parameter interface 4031 and a second parameter interface 4032. The first parameter interface 4031 is mounted on the second PCB substrate 41 and electrically connected to the first parameter circuit 431. The second parameter interface 4032 is mounted on the second PCB substrate 41 and electrically connected to the second parameter circuit 432. The first parameter interface 4031 and the second parameter interface 4032 are opposite to the second opening 131.

[0058] Optionally, the first parameter interface 4031 is located on the side of the first parameter area 4121 away from the main control area 411, and the second parameter interface 4032 is located on the side of the second parameter area 4122 away from the main control area 411.

[0059] The aforementioned panel 11, first side panel 12, second side panel 13, display screen 111, button 112, second PCB substrate 41, operation button 401, input / output interface 402, first parameter interface 4031, and second parameter interface 4032 effectively simplify the coordination between the various structures of the front shell 10 and the main control board 40. The structure is compact and the wiring is simple, thereby effectively reducing the size of the defibrillator and improving the reliability of the electrical connection between the various components of the main control board 40.

[0060] In some embodiments, the interface area 414, button area 413, main control area 411, and parameter area 412 are arranged along the length direction L of the main control board 40, and the first parameter area 4121 and the second parameter area 4122 are arranged along the width direction W of the main control board 40. This embodiment not only rationally arranges the positions of each functional circuit and reduces mutual interference between functional circuits, but also makes reasonable use of the space of the main control board 40, reducing the size of the main control board 40, thereby reducing the size of the defibrillator. In addition, the main control area 411 usually contains some large BGA (Ball Grid Array Package) packaged components, while the interface area 414 and button area 413 are subject to significant deformation due to the insertion and removal of terminals and the pressing of buttons. By separating the main control area 411 from the interface area 414 and button area 413, the impact of the interface area 414 and button area 413 on the large BGA packaged components in the main control area 411 can be effectively reduced.

[0061] In some embodiments, the distance between the electronic components located in the first parameter area 4121 and the electronic components located in the second parameter area 4122 is not less than 6.3 mm. The distance between the electronic components in the first parameter area 4121 and the electronic components in the second parameter area 4122 needs to meet a voltage of 3000Vdc to ensure safe operation of the device. By setting the distance between the electronic components in the first parameter area 4121 and the electronic components in the second parameter area 4122 to not less than 6.3 mm, the aforementioned safety requirements can be met.

[0062] In some embodiments, the main control board 40 further includes a third shielding cover 46 disposed in the first parameter area 4121, and the first parameter circuit 431 is located inside the third shielding cover 46. By placing the first parameter circuit 431 inside the third shielding cover 46, not only can the electromagnetic signals generated by the circuit modules outside the third shielding cover 46 be reduced to interfere with the electronic components inside the third shielding cover 46, but the electromagnetic signals generated by the electronic components inside the third shielding cover 46 can also be reduced to interfere with other circuit modules outside the third shielding cover 46, effectively solving the electromagnetic compatibility (EMC) problem in the system.

[0063] In some embodiments, the main control board 40 further includes a fourth shielding cover 47 disposed in the second parameter area 4122, and the second parameter circuit 432 is located inside the fourth shielding cover 47. By placing the second parameter circuit 432 inside the fourth shielding cover 47, not only can the interference of electromagnetic signals generated by circuit modules outside the fourth shielding cover 47 on electronic components inside the fourth shielding cover 47 be reduced, but the interference of electromagnetic signals generated by electronic components inside the fourth shielding cover 47 on other circuit modules outside the fourth shielding cover 47 can also be reduced, effectively solving the electromagnetic compatibility (EMC) problem in the system.

[0064] In some embodiments, the main control board 40 further includes a fifth shielding cover 48 disposed in the main control area 411, and the main control circuit 42 is located inside the fifth shielding cover 48. By placing the main control circuit 42 inside the fifth shielding cover 48, not only can the electromagnetic signals generated by the circuit modules outside the fifth shielding cover 48 be reduced to interfere with the electronic components inside the fifth shielding cover 48, but the electromagnetic signals generated by the electronic components inside the fifth shielding cover 48 can also be reduced to interfere with other circuit modules outside the fifth shielding cover 48, effectively solving the electromagnetic compatibility (EMC) problem in the system.

[0065] In some embodiments, the treatment parameter area 311 and the power management area 312 are both opposite to the parameter area 412, and the treatment charging area 313 and the treatment discharging area 314 are both opposite to the area formed by the combination of the button area 413 and the interface area 414. Optionally, the treatment parameter area 311 of the power board 30 is opposite to the first parameter area 4121 of the main control board 40, and the power management area 312 of the power board 30 is opposite to the second parameter area 4122 of the main control board 40. After the front shell 10 and the rear shell 20 are assembled, the corresponding areas of the main control board 40 and the power board 30 also need to meet 3000Vdc. In some embodiments, the treatment parameter area 311 of the power board 30 is opposite to the first parameter area 4121 of the main control board 40, and the treatment parameter area 311 and the first parameter area 4121 need to meet 3000Vdc. In some embodiments, the power management area 312 of the power board 30 and the second parameter area 4122 of the main control board 40 are opposite each other, and the power management area 312 and the second parameter area 4122 need to meet 3000Vdc.

[0066] Since the first parameter area 4121 and the second parameter area 4122 of the main control board 40, and the treatment parameter area 311 and the power management area 312 of the power supply board 30 are all equipped with small-signal analog circuits, by setting the treatment parameter area 311 of the power supply board 30 to be opposite to the first parameter area 4121 of the main control board 40, and the power management area 312 of the power supply board 30 to be opposite to the second parameter area 4122 of the main control board 40, mutual interference between the small-signal areas can be avoided. Here, small-signal areas refer to signals susceptible to electromagnetic interference, such as low-frequency and weak signals. By aligning the treatment charging area 313 and treatment discharging area 314 of the power board 30 with the area formed by the combination of the button area 413 and interface area 414 of the main control board 40, the treatment charging area 313 and treatment discharging area 314 of the power board 30 are kept away from the first parameter area 4121 and the second parameter area 4122 of the main control board 40. This prevents the large signal areas of the treatment charging area 313 and treatment discharging area 314 from interfering with the small signal areas of the first parameter area 4121 and the second parameter area 4122. Simultaneously, the button area 413 and interface area 414 of the main control board 40 are kept away from the treatment parameter area 311 and power management area 312 of the treatment board 30, preventing the large signal areas of the button area 413 and interface area 414 from interfering with the small signal areas of the treatment parameter area 311 and power management area 312, thus ensuring stable and normal operation of the device.

[0067] like Figure 8 As shown, Figure 8The illustration shows another layout of the interface area 414', button area 413', main control area 411', first parameter area 4121' and second parameter area 4122'. In this embodiment, the interface area 414', button area 413', main control area 411', first parameter area 4121' and second parameter area 4122' are arranged sequentially along the length direction L of the main control board 40.

[0068] like Figure 9 As shown, in some embodiments, the defibrillator further includes a connector 50, through which the power board 30 and the main control board 40 are connected. The connector 50 can be a connecting cable or a plug-in, etc. Exemplarily, the power board 30 also includes a main control board interface 39 for electrical connection with the main control board 40. The main control board interface 39 is located within the power management area 312. The main control board 40 also includes a power board interface 49 for connection with the power board 30. The power board interface 49 is located within the main control area 411. One end of the connector 50 is connected to the main control board interface 39, and the other end of the connector 50 is connected to the power board interface 49. With this implementation, safety issues caused by non-isolated side wiring crossing the isolated side can be avoided. It should be noted that the power board 30 and the main control board 40 are not limited to being connected using the connector 50. For example, the power board 30 and the main control board 40 can be electrically connected by soldering a PCB printed circuit board.

[0069] like Figure 1-5 As shown, in some embodiments, the defibrillator further includes a support 60, which is disposed in the cavity 101 formed by the front housing 10 and the rear housing 20. The support 60 is mounted on the rear housing 20, and the power board 30 is mounted on the support 60. Exemplarily, the power board 30 is mounted on the side of the support 60 facing the front housing 10.

[0070] In some embodiments, the defibrillator further includes a pacemaker plate 70, which is mounted on a bracket 60.

[0071] In some embodiments, the defibrillator further includes an AC / DC converter 80 mounted on the bracket 60, which converts external voltage into a voltage required by the defibrillator. Exemplarily, the AC / DC converter 80 is mounted on the side of the bracket 60 opposite to the front housing 10.

[0072] In some embodiments, the defibrillator further includes an energy storage capacitor 90, which is located on the side of the power board 30 opposite to the main control board 40.

[0073] In some embodiments, the defibrillator further includes a battery 100, and the back cover 20 has a battery housing 21 in which the battery 100 is detachably installed. It should be noted that in some other embodiments, the defibrillator may not have a battery 100 and a battery housing 21, and the defibrillator may be powered by an external power source. Of course, in some other embodiments, the defibrillator may have both a battery 100 and an external power supply interface, allowing the user to power the defibrillator using either the battery 100 or the external power supply interface, depending on ease of use.

[0074] Optionally, an air gap 102 is provided between the battery 100 and the wall of the battery compartment 21. The air gap 102 can accelerate the dissipation of heat generated by the battery 100 during operation, reducing the transfer of heat generated by the battery 100 to the interior of the rear shell 20 through the wall of the battery compartment 21. Optionally, an air gap 103 is also provided between the energy storage capacitor 90 and the wall of the battery compartment 21. The air gap 103 can accelerate heat dissipation, reducing the transfer of heat generated by the battery 100 to the energy storage capacitor 90 in the rear shell 20 through the wall of the battery compartment 21.

[0075] Understandably, the present invention can also be used for other medical devices besides defibrillators, and is not limited thereto.

[0076] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
