Description

Technical Field

[0001] This application relates to the field of medical device technology, and more particularly to a defibrillator. Background Technology

[0002] Cardiac arrest is an emergency. An automated external defibrillator (AED) is a portable, easy-to-operate first-aid device that can be used proficiently with minimal training and is specifically designed for on-site emergency care. However, individuals with significantly different physical capabilities (such as adults and children) require different defibrillation currents. Clinical evidence shows that the defibrillation current for children is significantly lower than that for adults, reducing the risk of cardiac damage and providing better protection. Therefore, AED products need to be equipped with both adult and child operating modes to meet the needs of different scenarios.

[0003] Currently, AED products on the market typically use buttons to switch between adult and child modes to meet the defibrillation needs of adults and children. While this method allows for switching between adult and child modes, it has several drawbacks. First, the operation is not easily identifiable; users need to press a button to select the mode, but there are no clear prompts to indicate whether the button is pressed correctly, which may lead to errors or delays. Second, the button design lacks clear indicators, making it difficult for users to intuitively understand whether adult or child mode is selected. Third, the presence of the button component can affect the reliability of the AED product. Finally, if the button malfunctions or needs replacement, subsequent maintenance costs will increase. Summary of the Invention

[0069] When using an AED, different defibrillation currents are required for individuals with significantly different physical functions (e.g., adults and children). Therefore, AED products need to be configured with two operating modes, one for adults and one for children, to meet the needs of different scenarios. Thus, the ability to quickly select the appropriate operating mode is crucial during AED defibrillation. The defibrillator provided in this application embodiment features a switching switch assembly. Switching between a first and second position using this assembly allows for easy and readily identifiable mode switching. Simultaneously, the circuit assembly uses sensors to identify different signals to switch operating modes, ensuring high reliability and long service life. The non-contact design, with the sensing element spaced apart from the sensor, also enables product miniaturization. The defibrillator provided in this application embodiment will be described in detail below.

[0070] Please see Figures 1 to 8 , Figure 1This application provides a defibrillator 10. The defibrillator 10 includes a housing 100, a circuit assembly 200, a switching assembly 300, a switching fixture 400, a sensing element 500, and electrode pads (not shown in the figure). For ease of assembly and disassembly, the housing 100 includes a front housing 110 and a rear housing 120. The circuit assembly 200 is disposed within the housing 100. The switching assembly 300 is spaced apart from the circuit assembly 200. The circuit assembly 200 includes a sensor 210 and a controller (not shown in the figure). The sensing element 500 is spaced apart from the sensor 210. The controller is used to control the defibrillator 10 to switch operating modes. The electrode pads can be electrically connected to the circuit assembly 200 through an interface on the housing 100. Of course, the electrode pads can also be electrically connected to the circuit assembly 200 in other ways. It is understood that the circuit assembly 200 can be a single circuit board, or two or more circuit boards, as long as they meet the circuit requirements of the defibrillator 10. This application does not impose any limitations on this.

[0071] This embodiment of the application achieves the switching of the defibrillator 10's operating mode by detecting different sensing signals from sensor 210. Specifically, the switching assembly 300 is used to switch between a first position and a second position. When the switching assembly 300 is in the first position, the sensing element 500 provides a first sensing signal to sensor 210. The sensor outputs a first switching signal based on the first sensing signal. The controller controls the defibrillator 10 to switch to the first operating mode based on the first switching signal and controls the circuit assembly 200 to generate a first defibrillation current. The electrode pads transmit the first defibrillation current to the object to be defibrillated, thereby achieving defibrillation of the object to be defibrillated. When the switching assembly 300 is in the second position, the sensor detects a second sensing signal and outputs a second switching signal based on the second sensing signal. The controller controls the defibrillator 10 to switch to the second operating mode based on the second switching signal and controls the circuit assembly 200 to generate a second defibrillation current. The electrode pads transmit the second defibrillation current to the object to be defibrillated, thereby achieving defibrillation of the object to be defibrillated. The switch assembly 300 is fixed by a switch fixing member 400, which is connected to the housing 100 and at least a portion of the switch assembly 300 is disposed between the switch fixing member 400 and the housing 100.

[0072] In some embodiments, the sensor 210 cooperates with the sensing element 500 to switch the operating mode of the defibrillator 10. Specifically, please refer to [link to relevant documentation]. Figure 3 and Figure 4 The sensing element 500, disposed on the switching assembly 300, can generate a sensing signal. The switching assembly 300 is used to switch between a first position and a second position. When the switching assembly 300 is in the first position, such as... Figure 3As shown, when the sensing element 500 approaches the sensor 210, the sensing element 500 generates a first sensing signal. The sensor 210 detects that the first sensing signal is greater than or equal to a first threshold. At this time, the sensor outputs a first switching signal based on the first sensing signal. The controller controls the defibrillator 10 to switch to a first working mode based on the first switching signal and controls the circuit assembly 200 to generate a first defibrillation current. The electrode pads transmit the first defibrillation current to the object to be defibrillated, thereby realizing defibrillation of the object to be defibrillated. When the switching switch assembly 300 is in the second position, such as Figure 4 As shown, the sensing element 500 is moved away from the sensor 210. The sensing element 500 generates a second sensing signal. The sensor 210 detects that the second sensing signal is less than or equal to a second threshold. At this time, the sensor outputs a second switching signal based on the second sensing signal. The controller controls the defibrillator 10 to switch to a second operating mode based on the second switching signal and controls the circuit assembly 200 to generate a second defibrillation current. The electrode pads transmit the second defibrillation current to the object to be defibrillated, thereby realizing defibrillation of the object to be defibrillated. The switching switch assembly 300 is fixed by the switching switch fixing member 400. The switching switch fixing member 400 is connected to the housing 100, and at least a portion of the switching switch assembly 300 is disposed between the switching switch fixing member 400 and the housing 100.

[0073] Specifically, the signal value of the second sensing signal can be 0. That is, when the sensor 210 cannot detect the second sensing signal, it can be considered that the signal value of the second sensing signal detected by the sensor 210 is 0, which is within the range where the second sensing signal is less than or equal to the second threshold.

[0074] Understandably, the first working mode can be the child mode, and the second working mode can be the adult mode. Of course, if the corresponding defibrillation current changes, the first and second working modes can also be other modes.

[0075] In one embodiment, the sensing element 500 can be a magnetic object such as a magnet, and the sensor 210 can be a Hall sensor such as a Hall switch. The induction signal generated by the magnet is a magnetic induction signal, and the switching signal output by the Hall switch can be a level signal state, such as a low-level signal or a high-level signal. When the switching component 300 is in the first position, the magnet in the switching component 300 is close to the Hall switch. At this time, the Hall switch detects that the first magnetic induction signal generated by the magnet is greater than or equal to a first threshold, for example, the first threshold is 60Gs, which is considered that the Hall switch can detect the magnetic induction signal generated by the magnet, and thus outputs the first switching signal, such as a low-level signal. After receiving the low-level signal, the controller controls the circuit component 200 to generate a first defibrillation current according to the low-level signal. The electrode plate transmits the first defibrillation current to the person to be defibrillated. At this time, the first defibrillation current can be used for defibrillation of children, that is, the defibrillator 10 is controlled to switch to the child mode. For example, the shock energy corresponding to the first defibrillation current can be 10J to 200J, specifically 50J, 70J or 100J. When the patient to be defibrillated is a child, the defibrillator observes whether the switching component 300 is in the first position. If the switching component 300 is not in the first position, it is moved to the first position before defibrillation is performed. If the switching component 300 is in the first position, defibrillation can be performed directly on the patient.

[0076] Furthermore, when the switching assembly 300 is in the second position, the magnet in the switching assembly 300 is far from the Hall switch. At this time, the Hall switch detects that the second magnetic induction signal generated by the magnet is less than or equal to the second threshold, for example, the second threshold is 45Gs, which is considered that the Hall switch cannot detect the magnetic induction signal generated by the magnet, and thus outputs the second switching signal, such as a high-level signal. After receiving the high-level signal, the controller controls the circuit assembly 200 to generate a second defibrillation current according to the high-level signal. The electrode pads transmit the second defibrillation current to the person to be defibrillated. At this time, the second defibrillation current can be used for adult defibrillation, that is, the defibrillator 10 is controlled to switch to adult mode. For example, the shock energy corresponding to the second defibrillation current can be 100J to 360J, specifically 200J, 300J or 360J. When the person to be defibrillated is an adult, the defibrillator operator observes whether the switching assembly 300 is in the second position. If the switching assembly 300 is not in the second position, the switching assembly 300 is moved to the second position and then the person to be defibrillated is defibrillated. If the switching component 300 is in the second position, defibrillation can be performed directly on the object to be defibrillated.

[0077] It is understandable that when the distance between the magnet in the switching assembly 300 and the Hall switch is far enough, the Hall switch cannot detect the magnetic induction signal generated by the magnet. At this time, it can be regarded that the Hall switch detects the magnetic induction signal generated by the magnet as 0Gs, which is within the range where the magnetic induction signal generated by the magnet detected by the Hall switch is less than or equal to the second threshold.

[0078] Understandably, the level signal state output by the Hall switch is independent of adult or child mode, and only related to the internal layout of the defibrillator. If the internal layout of the defibrillator 10 changes, and the magnet in the switching assembly 300 is in the same position, the level signal state output by the Hall switch can also change. Specifically, when the switching assembly 300 is in the first position, the magnet in the switching assembly 300 is close to the Hall switch. At this time, the Hall switch detects that the first magnetic induction signal generated by the magnet is greater than or equal to the first threshold, and the Hall switch can also output a high-level signal. After receiving the high-level signal, the controller controls the circuit assembly 200 to generate a first defibrillation current according to the high-level signal. The electrode plate transmits the first defibrillation current to the person to be defibrillated. At this time, the first defibrillation current can be used for child defibrillation, that is, the defibrillator 10 is controlled to switch to child mode. When the switching component 300 is in the second position, the magnet in the switching component 300 moves away from the Hall switch. At this time, the Hall switch detects that the second magnetic induction signal generated by the magnet is less than or equal to the second threshold, and the Hall switch can also output a low-level signal. After receiving the low-level signal, the controller controls the circuit component 200 to generate a second defibrillation current according to the low-level signal. The electrode plate transmits the second defibrillation current to the person to be defibrillated. At this time, the second defibrillation current can be used for adult defibrillation, that is, the defibrillator 10 is controlled to switch to adult mode.

[0079] This embodiment, by setting a switching assembly 300 on the defibrillator 10 and placing the sensing element 500 within the switching assembly 300, in cooperation with a fixed sensor 210, allows the distance between the sensing element 500 and the sensor 210 to be changed by switching the switching assembly 300 to different positions. This alters the sensing signal generated by the sensing element 500 detected by the sensor 210, thereby enabling the switching of the defibrillator 10's operating mode through the cooperation of the sensor 210 and the sensing element 500. This method offers high reliability. Furthermore, the sensor 210 and the sensing element 500 themselves are small in size, reducing the overall size of the switching assembly 300. The cooperation between the sensor 210 and the sensing element 500 also reduces the distance the switching assembly 300 moves between the first and second positions. The non-contact design, with the sensing element 500 and the sensor 210 spaced apart, further minimizes the overall size of the defibrillator's switching structure, enabling miniaturization of the defibrillator 10. Additionally, the Hall switch used in this embodiment features contactless operation, low power consumption, long lifespan, high response frequency, and small size, allowing for reliable operation in various harsh environments. In addition, the present application embodiment achieves the switching of the defibrillator 10's working mode by switching the switching component 300 between the first position and the second position. The user can quickly and intuitively feel the change in the position of the switching component 300 on the defibrillator 10 when switching the working mode. The operation is simple and easy to identify, thereby preventing the user from accidentally using the wrong working mode. The user can also quickly know whether the currently selected working mode is adult or child mode based on the position of the switching component 300 on the defibrillator 10. It is simple and easy to use.

[0080] In another embodiment, the sensing element 500 can be a magnetic object such as a magnet, and the sensor 210 can be a Hall sensor. The induction signal generated by the magnet is a magnetic induction signal, and the switching signal output by the Hall sensor can be a voltage signal. The Hall sensor can convert a changing magnetic field into a change in output voltage. The Hall voltage changes with the strength of the magnetic field generated by the magnet; the stronger the magnetic field, the higher the voltage, and the weaker the magnetic field, the lower the voltage. Specifically, when the switching assembly 300 is in the first position, the magnet in the switching assembly 300 is close to the Hall sensor. After detecting the first magnetic induction signal generated by the magnet in the switching assembly 300, the Hall sensor outputs a first switching signal, such as a first voltage value. If the controller receives a first voltage value that is greater than or equal to a first voltage threshold, the control circuit assembly 200 generates a first defibrillation current. The electrode plates transmit the first defibrillation current to the object to be defibrillated. At this time, the first defibrillation current can be used for defibrillation of children, that is, the defibrillator 10 is switched to child mode. When the switching assembly 300 is in the second position, the magnet in the switching assembly 300 is away from the Hall sensor. After detecting the second magnetic induction signal generated by the magnet in the switching assembly 300, the Hall sensor outputs a second switching signal, such as a second voltage value. If the controller receives a second voltage value that is less than or equal to a second voltage threshold, the control circuit assembly 200 generates a second defibrillation current. The electrode pads transmit the second defibrillation current to the person to be defibrillated. At this time, the second defibrillation current can be used for adult defibrillation, that is, the defibrillator 10 is switched to adult mode. It is understood that if the internal layout of the defibrillator 10 is changed, the correspondence between the voltage value output by the Hall sensor and the operating mode can also be changed. This application does not impose any restrictions on this.

[0081] In another embodiment, the switching assembly 300 may also be provided with multiple sets of magnetic objects, and the circuit assembly 200 includes multiple sets of Hall sensors corresponding to the multiple sets of magnetic objects. The switching of the defibrillator 10 into different operating modes is controlled by the cooperation between the multiple sets of magnetic objects and the multiple sets of Hall sensors. Specifically, the switching assembly 300 is provided with a first magnetic object and a second magnetic object, and the circuit assembly 200 includes corresponding first Hall sensors and second Hall sensors. When the switching assembly 300 is in the first position, the first magnetic object is close to the first Hall sensor, and the second magnetic object is far away from the second Hall sensor. At this time, the first Hall sensor detects a first sensing signal and outputs a first switching signal based on the first sensing signal. The controller controls the defibrillator 10 to switch to the first operating mode based on the first switching signal. When the switching assembly 300 is in the second position, the first magnetic object is far away from the first Hall sensor, and the second magnetic object is close to the second Hall sensor. At this time, the second Hall sensor detects a second sensing signal and outputs a second switching signal based on the second sensing signal. The controller controls the defibrillator 10 to switch to the second operating mode based on the second switching signal. It is understood that there are many other ways in which the multiple sets of magnetic objects and the multiple sets of Hall sensors can cooperate, which will not be elaborated here.

[0082] It is understood that the sensing element can be a structure that generates a sensing signal, such as a magnetic material generating a magnetic induction signal, or it can be a medium for propagating the sensing signal, such as a light-transmitting plate propagating a light signal. In some embodiments, the sensor 210 can be a light sensor, which detects different light signals to switch the operating mode of the defibrillator 10. The sensing element 500 can be a light-transmitting part, where the first sensing signal is a first light signal and the second sensing signal is a second light signal, and either the first or second light signal can propagate through the light-transmitting part. When the switching assembly 300 is in the first position, it can provide the first light signal to the light sensor through the light-transmitting part. The light sensor detects that the first light signal is greater than or equal to a first threshold. At this time, the sensor outputs a first switching signal based on the first light signal, and the controller controls the defibrillator 10 to switch to the first operating mode based on the first switching signal. When the switching assembly is in the second position, the light sensor detects that the second light signal is less than or equal to a second threshold. The light sensor then outputs a second switching signal based on the second light signal, and the controller controls the defibrillator 10 to switch to the second operating mode based on the second switching signal. The optical sensor used in this embodiment has the characteristics of being contactless, low power consumption, low cost, and small size, and its structure is simple and easy to use.

[0083] It is understandable that when the switching component 300 is in the first position, the light signal can reach the light sensor through the light-transmitting part, and the light sensor can detect the light signal, which is within the range where the light sensor detects a first light signal greater than or equal to a first threshold. When the switching component 300 is in the second position, the light-transmitting part is blocked, thereby blocking the propagation path of the light signal to the light sensor. The light sensor cannot detect the light signal, which can be regarded as the signal value of the second light signal detected by the light sensor being 0, which is within the range where the light sensor detects a second light signal less than or equal to a second threshold.

[0084] In one embodiment, specifically, please refer to Figure 7 and Figure 8 To ensure the aesthetics and overall appearance of the defibrillator 10, a switch fixing member 400 is disposed inside the housing 100, which has an opening 112. The light-transmitting portion includes a first light-transmitting portion 510 and a second light-transmitting portion 520. The first light-transmitting portion 510 is disposed on the switch assembly 300, and the second light-transmitting portion 520 is disposed on the switch fixing member 400. The orthographic projections of the housing opening 112, the second light-transmitting portion 520, and the sensor 210 onto the displacement plane of the switch assembly 300 at least partially overlap. When the switch assembly 300 is in the first position, the orthographic projections of the housing opening 112, the first light-transmitting portion 510, and the second light-transmitting portion 520 onto the displacement plane of the switch assembly 300... When the orthographic projections of the plane containing the displacement surface at least partially overlap, light can enter through the housing opening 112, pass through the first light-transmitting part 510 and the second light-transmitting part 520, and reach the light sensor. The light sensor then detects the light signal and outputs a first switching signal. When the switching assembly 300 is in the second position, the orthographic projections of the first light-transmitting part 510 and the second light-transmitting part 520 on the plane containing the displacement surface of the switching assembly 300 do not overlap, or the orthographic projections of the housing opening 112 and the first light-transmitting part 510 on the plane containing the displacement surface of the switching assembly 300 do not overlap. In this case, the propagation path of light from the housing opening 112 to the light sensor is blocked, and the light sensor cannot detect the light signal. The light sensor then outputs a second switching signal.

[0085] In another embodiment, a switch fixing member 400 is disposed on the outside of the housing 100, and the switch fixing member 400 has an opening 460; the light-transmitting portion includes a first light-transmitting portion 510 and a third light-transmitting portion, the first light-transmitting portion 510 is disposed on the switch assembly 300, and the third light-transmitting portion is disposed on the housing 100, wherein the orthographic projections of the switch fixing member opening 460, the third light-transmitting portion, and the sensor 210 on the plane where the displacement surface of the switch assembly 300 is located at least partially overlap; when the switch assembly 300 is in the first position, the orthographic projections of the switch fixing member opening 460, the first light-transmitting portion 510, and the third light-transmitting portion on the plane where the displacement surface of the switch assembly 300 is located... When there is a partial overlap, light can enter through the opening 460 of the switch fixing member, pass through the first light-transmitting part 510 and the third light-transmitting part, and reach the light sensor. The light sensor then detects the light signal and outputs the first switching signal. When the switch assembly 300 is in the second position, the orthographic projections of the first light-transmitting part 510 and the third light-transmitting part on the plane where the displacement surface of the switch assembly 300 is located do not coincide, or the orthographic projections of the opening 460 of the switch fixing member and the first light-transmitting part 510 on the plane where the displacement surface of the switch assembly 300 is located do not coincide. In this case, the propagation path of light from the opening 460 of the switch fixing member to the light sensor is blocked, and the light sensor cannot detect the light signal. The light sensor then outputs the second switching signal.

[0086] In another embodiment, when the switch fixing member 400 is disposed inside the housing 100, the first light-transmitting part 510 is disposed on the housing 100, the switch fixing member 400 includes a second light-transmitting part 520, and the orthographic projections of the first light-transmitting part 510, the second light-transmitting part 520 and the sensor 210 on the plane where the displacement surface of the switch assembly 300 is located at least partially overlap; when the switch fixing member 400 is disposed outside the housing 100, the first light-transmitting part 510 is disposed on the switch fixing member 400, the housing 100 includes a second light-transmitting part 520, and the orthographic projections of the first light-transmitting part 510, the second light-transmitting part 520 and the sensor 210 on the plane where the displacement surface of the switch assembly 300 is located at least partially overlap. When the switching assembly 300 switches between the first position and the second position, it controls the propagation path of the light signal to the light sensor to open or close by opening or blocking the first light-transmitting part 510, thereby controlling the defibrillator 10 to switch working modes according to the different light signals detected by the light sensor.

[0087] In this embodiment, by changing the position of the switching component, the propagation path of light from the opening to the light sensor is connected or disconnected, thereby determining whether the light sensor can detect the light signal, so as to realize the defibrillator 10 switching between the first working mode and the second working mode.

[0088] In some embodiments, please refer to Figure 2 The switching assembly 300 includes a positioning member 310 and an operating member 320. A sensing element 500 is fixed within the operating member 320; the fixing method is not limited, for example, interference fit. The sensing element 500 can generate a sensing signal to cooperate with the sensor 210 to switch the operating mode of the defibrillator 10. By operating the operating member 320, the switching assembly 300 can be switched between a first position and a second position. In one embodiment, the operating member 320 includes a protrusion 321 and a fixing part 322 connected to the protrusion 321. The fixing part 322 is disposed between the switching fixing member 400 and the housing 100. For ease of operation, when switching the position of the switching assembly 300, the user can move the protrusion 321, thereby moving the fixing part 322 between the switching fixing member 400 and the housing 100 to switch between the first and second positions.

[0089] In one embodiment, for the aesthetic appeal and overall appearance of the defibrillator 10, a switch fixing member 400 is disposed inside the housing 100, the housing 100 having an opening 112; a protrusion 321 extends out of the housing 100 through the opening 112, and the protrusion 321 moves within the opening 112 to achieve switching of the switch assembly 300 between a first position and a second position. For details, please refer to... Figure 3 and Figure 4 To allow the user to operate the switch assembly 300 by moving the protrusion 321, an opening 112 is provided on the housing 100, and the protrusion 321 extends out of the opening 112, allowing the user to directly see the protrusion 321 of the switch assembly 300. The opening 112 allows the protrusion 321 to move between a first position and a second position. It is understood that the length of the opening 112 along the displacement direction of the switch assembly 300 is not less than the distance between the first position and the second position along the displacement direction of the switch assembly 300, thereby ensuring that the switch assembly 300 can be operated in place when switching working modes. At the same time, the length of the opening 112 along the displacement direction of the switch assembly 300 needs to be less than the length of the fixing part 322 along the displacement direction of the switch assembly 300, or the length of the opening 112 perpendicular to the displacement direction of the switch assembly 300 needs to be less than the length of the fixing part 322 perpendicular to the displacement direction of the switch assembly 300, thereby ensuring that the switch assembly 300 does not disengage from the opening 112 during movement within the opening 112. Correspondingly, the fixing part 322 is disposed inside the housing 100 and between the switch fixing part 400 and the housing 100, which can ensure that the switch assembly 300 can move between the first position and the second position, and also ensure that it does not come out of the opening 112 during the movement.

[0090] In some embodiments, to improve the aesthetics of the defibrillator 10, the surface of the defibrillator 10 is made as flat as possible, reducing structures protruding from the overall surface of the defibrillator 10. A portion of the housing 100 is recessed towards the inside of the housing 100 to form a receiving cavity 111, and at least a portion of the protrusion 321 extends from the opening 112 into the receiving cavity 111. In particular, in one embodiment, the height of the protrusion 321 does not exceed the height of the sidewall of the receiving cavity 111, so that the switching assembly 300 does not protrude from the overall surface of the defibrillator 10, enhancing the product's aesthetics.

[0091] In some embodiments, the switch fixing member 400 includes a support portion 410 and a connecting portion 420 parallel to the fixing portion 322. The support portion 410 supports the movement of the fixing portion 322 to enable the switch assembly 300 to switch between a first position and a second position. The connecting portion 420 is used to connect to the housing 100. The switch fixing member 400 also includes a sealing portion 430 connected to the support portion 410 and extending in a direction away from the support portion 410. The sealing portion 430 is connected to the connecting portion 420, and a seal 600 is provided between the sealing portion 430 and the housing 100. The space defined by the sealing portion 430 and the support portion 410 is used to accommodate the movement of the fixing portion 322 and to allow the switch assembly 300 to switch between the first position and the second position.

[0092] Specifically, please refer to Figure 1 , Figure 3 and Figure 4 The switch holder 400 has a recessed switch receiving cavity for accommodating the switch assembly 300 to switch between a first position and a second position. The bottom wall of the switch receiving cavity forms a support portion 410, and the surrounding side walls form sealing portions 430. A connecting portion 420 is disposed on the outside of at least one side wall of the switch receiving cavity; it is not limited to any specific type, as long as it can connect to the housing 100. Figure 1 As shown, the connecting part 420 is disposed on the outer side of the two opposite side walls of the switch receiving cavity, thereby ensuring the reliability of the connection between the switch fixing part 400 and the housing 100. It is understood that the connecting part 420 can be connected to the housing 100 by screws or other connecting parts, or it can be connected to the housing 100 by fastening, gluing, or other means, without limitation.

[0093] Since the housing 100 of the defibrillator 10 has an opening 112, in order to ensure the reliability of the internal circuit components 200, a sealing element 600 is provided between the sealing part 430 and the housing 100, thereby isolating the circuit components 200 from the external environment and achieving waterproof and dustproof protection for the internal components of the housing 100. In some embodiments, the sealing element 600 is an annular sealing element. During assembly, the sealing element 600 is first pasted onto the inside of the housing 100, located around the opening 112, and then the switch fixing element 400 is connected to the housing 100. After the switch fixing element 400 is fixed, the sealing part 430 is pressed against the sealing element 600, thereby achieving the function of waterproof and dustproof protection.

[0094] It is understood that the connecting portion 420 and the sealing portion 430 of the switch fixing member 400 can be the same part. For example, the switch fixing member 400 has a recessed switch receiving cavity, the bottom wall of which forms a support portion 410. One side of the sealing member 600 is attached to the housing 100, and the other side is attached to the surrounding side walls of the switch receiving cavity, thereby simultaneously achieving the fixing of the switch fixing member 400 and the waterproofing and dustproofing of the internal components of the housing 100. Of course, the switch fixing member 400 can also achieve fixing and waterproofing through other structural forms, which are not limited here.

[0095] It is understood that the connecting portion 420 and the sealing member 600 of the switch fixing member 400 can be connected to the housing around the periphery of the housing forming the receiving cavity 111, or to the housing on the bottom wall of the housing forming the receiving cavity 111; the connection position is not limited here. Of course, the shape of the switch fixing member 400 can be any shape, such as square, round, or triangular, as long as it can accommodate the switching movement of the switch assembly 300 between the first and second positions; there are no restrictions here.

[0096] In some embodiments, a tactile feedback indicating whether the switch has been switched to a first position or a second position is provided between the switch assembly 300 and the switch holder 400. Specifically, the protrusion 321 of the switch assembly 300 has an open cavity 323, the opening of which faces the support portion 410 of the switch holder 400; the switch assembly 300 also includes a positioning member 310, at least a portion of which is disposed within the cavity 323, and the positioning member 310 is movable within the cavity 323 along the extending direction of the protrusion 321; the switch holder 400 has a first positioning cavity 440 and a second positioning cavity 450 on the side facing the switch assembly 300; when the switch assembly 300 is in the first position, a portion of the positioning member 310 extends from the opening of the cavity 323 into the first positioning cavity 440; when the switch assembly 300 is in the second position, a portion of the positioning member 310 extends from the opening of the cavity 323 into the second positioning cavity 450. It is understandable that the positioning component 310 can fall into the first positioning cavity 440 or the second positioning cavity 450 by any means such as gravity, elasticity, or magnetism, and no restrictions are imposed here.

[0097] During the toggle of the switch assembly 300, through the up-and-down movement of the positioning member 310 and the cooperation between the positioning cavity of the switch fixing member 400, when the switch assembly 300 is switched to the first or second position, there will be a clear tactile and / or audible prompt that the positioning member 310 has fallen into the positioning cavity of the switch fixing member 400, thereby informing the user that the corresponding working mode has been switched and the switch is in place, thus avoiding misuse of the working mode.

[0098] Please see Figure 5 The positioning member 310 is disposed within the cavity 323 of the protrusion 321 of the switch assembly 300, and can move within the cavity 323 along the extending direction of the protrusion 321. In one embodiment, when the switch assembly 300 is in a first position or a second position, the portion of the positioning member 310 extending out of the opening of the cavity 323 is a hemispherical protrusion, and the first positioning cavity 440 and the second positioning cavity 450 cooperating with the hemispherical protrusion are hemispherical recesses. The design of the hemispherical protrusion and the hemispherical recess can reduce the resistance when the user toggles the switch assembly 300, making it more convenient and easier to use. During the toggling process of the switch assembly 300, such as Figure 5As shown, the switch assembly 300 is in the second position. At this time, the hemispherical protrusion of the positioning member 310 falls into the second positioning cavity 450. When the switch assembly 300 needs to be switched from the second position to the first position, the hemispherical protrusion moves out of the hemispherical recess of the second positioning cavity 450. The positioning member 310 moves away from the second positioning cavity 450 along the extension direction of the protrusion 321 until it is flush with the surface of the support 410. When the switch assembly 300 reaches the first position, the hemispherical protrusion falls into the hemispherical recess of the first positioning cavity 440. At this time, the user can feel the tactile and audible prompts of switching to the correct position.

[0099] In another embodiment, a switch fixing member 400 is disposed on the outside of the housing 100, and the switch fixing member 400 has an opening 460; a protrusion 321 extends out of the switch fixing member 400 through the opening 460, and the protrusion 321 moves within the opening 460 to achieve switching of the switch assembly 300 between a first position and a second position. This solution avoids openings on the housing 100 and directly achieves dust and water protection for the internal components through the housing 100 itself. For the aesthetic appearance of the defibrillator 10, and to make the surface of the defibrillator 10 as flat as possible and reduce structures protruding from the overall surface of the defibrillator 10, a portion of the housing 100 is recessed towards the inside of the housing 100 to form a receiving cavity 111, and at least a portion of the switch assembly 300 and / or at least a portion of the switch fixing member 400 are disposed within the receiving cavity 111. Specifically, in some embodiments, both the switching switch assembly 300 and the switching switch fixing member 400 are disposed within the receiving cavity 111, and the heights of both the switching switch assembly 300 and the switching switch fixing member 400 do not exceed the height of the side wall of the receiving cavity 111, ensuring that neither the switching switch assembly 300 nor the switching switch fixing member 400 protrudes from the overall surface of the defibrillator 10, thus enhancing the product's aesthetics. It is understood that the relative dimensions, shape, structure, etc., of the switching switch fixing member 400 and its opening 460 relative to the switching switch assembly 300 are similar to those in the above embodiments, and will not be elaborated upon here.

[0100] Specifically, in some embodiments, please refer to Figure 6A portion of the housing 100 is recessed inward to form a receiving cavity 111. A portion of the switch assembly 300 is disposed within the receiving cavity 111. The switch fixing member 400 is disposed on the outside of the housing 100 and covers the receiving cavity 111. The switch fixing member 400 has an opening 460, and a protrusion 321 extends out of the switch fixing member 400 and out of the receiving cavity 111 through the opening 460, so that the user can directly see the protrusion 321 of the switch assembly 300. Of course, both the switch assembly 300 and the switch fixing member 400 can be disposed within the receiving cavity 111; the housing 100 can also be without a receiving cavity, and the switch assembly 300 and the switch fixing member 400 can be directly disposed on the outside of the housing 100, as long as the switch assembly 300 can be movably disposed on the outside of the housing 100, there is no limitation here. It is understood that the switch fixing part 400 can be connected to the housing 100 by screws or other connecting parts, or the switch fixing part 400 can be connected to the housing 100 by snap-fit, adhesive or other means, and there are no restrictions on this.

[0101] In some embodiments, a tactile feedback indicating whether the switch assembly 300 has switched to a first position or a second position is engaged is provided between the switch assembly 300 and the housing 100. Specifically, the protrusion 321 of the switch assembly 300 has an open cavity 323, the opening of which faces the inside of the housing 100; the switch assembly 300 also includes a positioning member 310, at least a portion of which is disposed within the cavity 323, and the positioning member 310 is movable within the cavity 323 along the extending direction of the protrusion 321; the housing 100 has a first positioning cavity 440 and a second positioning cavity 450 on the side facing the switch assembly 300; when the switch assembly 300 is in the first position, a portion of the positioning member 310 extends from the opening of the cavity 323 into the first positioning cavity 440; when the switch assembly 300 is in the second position, a portion of the positioning member 310 extends from the opening of the cavity 323 into the second positioning cavity 450. During the toggle switch assembly 300's operation, the up-and-down movement of the positioning member 310 and the engagement with the positioning cavity of the toggle switch fixing member 400 provide a clear tactile and audible feedback when the toggle switch assembly 300 is switched to the first or second position. This informs the user that the corresponding operating mode has been switched and is in place, preventing misuse of the operating mode. The engagement of the positioning member 310 with the first positioning cavity 440 and the second positioning cavity 450 is similar to that in the above embodiment and will not be described in detail here.

[0102] In some embodiments, the outer surface of the housing 100 is provided with a first operating mode mark and a second operating mode mark; when the switching assembly 300 is in the first position, the protrusion 321 is located in the associated area of ​​the first operating mode mark, for indicating that the defibrillator 10 is in the first operating mode; when the switching assembly 300 is in the second position, the protrusion 321 is located in the associated area of ​​the second operating mode mark, for indicating that the defibrillator 10 is in the second operating mode. For example, when the first position is to the left of the second position, switching the switch assembly 300 to the first position, with the protrusion 321 on the left, placing the first operating mode mark on the left, top, or bottom of the protrusion 321 at this time is within the associated area of ​​the first operating mode mark, indicating that the defibrillator 10 is in the first operating mode. Similarly, switching the switch assembly 300 to the second position, with the protrusion 321 on the right, placing the second operating mode mark on the right, top, or bottom of the protrusion 321 at this time is within the associated area of ​​the second operating mode mark, indicating that the defibrillator 10 is in the second operating mode; and vice versa. The positions of the first and second operating mode marks are not limited here, as long as they can be used to indicate that the defibrillator 10 is in the first or second operating mode.

[0103] In some embodiments, a first operating mode marker is used to indicate that the defibrillator 10 is in child operating mode, and a second operating mode marker is used to indicate that the defibrillator 10 is in adult operating mode. The first and second operating mode markers can be text, images, graphics, etc., and are not limited thereto.

[0104] By aligning the protrusion 321 of the switching assembly 300 with the associated areas of the first working mode mark and the second working mode mark, the defibrillator 10 can be identified as being in the first working mode or the second working mode. This provides clear prompts to the user, making it more intuitive and allowing them to know the current working mode of the defibrillator, thus avoiding misuse of the working mode.

[0105] In some embodiments, when the switching assembly 300 moves from the first position to the second position, the sensing element 500 continuously moves away from the sensor 210 in the displacement direction parallel to the switching assembly 300; when the switching assembly 300 moves from the second position to the first position, the sensing element 500 continuously moves closer to the sensor 210 in the displacement direction parallel to the switching assembly 300.

[0106] It is understood that when the switch assembly 300 switches between the first and second positions, it can translate or rotate within the housing opening 112 or the switch fixing opening 460, as long as the distance between the sensor 210 and the sensing element 500 can be changed; no limitation is imposed here. Specifically, when switching between the first and second positions, if the switch assembly 300 translates within the housing opening 112 or the switch fixing opening 460, the sensing element 500 can be located at any part of the operating member 320, such as the protrusion 321; for example, the switch assembly 300 can be a toggle switch. When switching between the first and second positions, if the switch assembly 300 rotates within the housing opening 112 or the switch fixing opening 460, the sensing element 500 can be located at any part of the operating member 320 other than the rotation axis, such as any end of the fixing part 322.

[0107] In one embodiment, when switching between a first position and a second position, the switch assembly 300 rotates within the housing opening 112 or the switch fixing opening 460, and the rotation axis of the switch assembly 300 is perpendicular to or approximately perpendicular to the plane containing the housing opening 112; for example, the switch assembly 300 may be a knob. In another embodiment, when switching between a first position and a second position, the switch assembly 300 rotates within the housing opening 112 or the switch fixing opening 460, and the rotation axis of the switch assembly 300 is parallel to or approximately parallel to the plane containing the housing opening 112; for example, the switch assembly 300 may be a lever or a roller, etc.

[0108] The defibrillator 10 provided in this application changes the sensing signal detected by the sensor 210 by switching the switching component 300 to different positions, thereby causing the sensor 210 to output different switching signals, thus triggering the switching of the defibrillator 10's working mode. This method has high reliability and long service life. Moreover, the sensing element 500 and the sensor 210 themselves are small in size, which can reduce the size of the switching component 300. The non-contact design with the sensing element 500 and the sensor 210 spaced apart also makes the overall size of the defibrillator's switching structure small, thereby achieving miniaturization of the defibrillator 10. At the same time, when switching the working mode, the switching component 300 switches between the first position and the second position, which allows the user to quickly and intuitively feel the position change of the switching component 300 on the defibrillator 10. The user can also quickly know the currently selected working mode based on the position of the switching component 300 on the defibrillator 10. The operation is simple and easy to identify.
