Since the application time of the voltage is short when defibrillation is performed, by ensuring that the applied energy is within a preset joule value, for example, within 360J (joule), no influence is exerted on human safety, and defibrillation can be performed effectively.

It can be understood that the height of the high-voltage device 22 in the accommodating space 32 is gradually increased in the arrangement direction Y1 to conform to the accommodating space 32 with one end being arc-shaped, so that the accommodating space 32 is fully utilized, the compact layout of the devices on the circuit board 2 and the energy storage capacitor 3 is realized, and the structural compactness of the devices inside the defibrillation apparatus 100 is further improved.

That is, the height of at least a part of the high-voltage device 33 is changed in accordance with the height change of the receiving space 32. For example, the high-voltage device 33 with a small height is located in the portion of the receiving space 32 with a small height, and the high-voltage device 33 with a large height is located in the portion of the receiving space 32 with a large height, so that the high-voltage device 33 can fully utilize the receiving space 32, the utilization rate of the receiving space 32 is improved, and the structural compactness of the defibrillation apparatus 100 is further improved.

Referring to fig. 5, the high voltage device 33 includes a therapeutic charging module 331 and a therapeutic discharging module 332 arranged along the axial direction of the energy storage capacitor 3. The therapy charging module 331 is electrically connected to the energy storage capacitor 3 to charge the energy storage capacitor 3. The therapy discharge module 332 is electrically connected to the energy storage capacitor 3 to discharge the stored energy in the energy storage capacitor 3 and form a defibrillation current.

By arranging the treatment charging module 331 and the treatment discharging module 332 in the axial direction of the energy storage capacitor 3, the heights of the devices in the treatment charging module 331 and the treatment discharging module 332 are arranged in a gradient manner, so that the treatment charging module 331 and the treatment discharging module 332 can make full use of the accommodating space 32, and the arrangement tightness of the treatment charging module 331, the treatment discharging module 332 and the energy storage capacitor 3 is improved.

Referring to fig. 5 and 6, the defibrillation apparatus 100 further includes a discharge interface 41 and defibrillation electrode pads 42. The discharge interface 41 is disposed between the rear case 12 and the front case 11 and electrically connected to the therapeutic discharge module 332. At least part of the discharge interface 41 is provided in the through hole 110 of the front case 11. The defibrillation electrode pads 42 are provided outside the housing space formed by the front and

rear housings

11 and 12. The electrical connection wire of the defibrillation electrode pad 42 is electrically connected to the discharge interface 41 through the through hole 110 to transmit defibrillation current to a subject to be defibrillated.

Specifically, when the defibrillation electrode pad 42 defibrillates the subject to be defibrillated, after the energy storage capacitor 3 is charged by the therapy charging module 331, the therapy discharging module 332 is configured to transmit the electric energy in the energy storage capacitor 3 to the defibrillation electrode pad 42 through the discharging interface 41, and the defibrillation electrode pad 42 transmits the defibrillation current to the subject to be defibrillated, so as to defibrillate the subject to be defibrillated.

The defibrillation electrode pads 42 are arranged outside the front shell 11 and the rear shell 12, so that the defibrillation electrode pads 42 are attached to a main body to be defibrillated; at least part of the discharge interface 41 is arranged in the through hole 110 of the front shell 11, so that the defibrillation electrode pads 42 can be electrically connected to the treatment discharge module 332 inside the front shell 11 and the rear shell 12 conveniently through the discharge interface 41, and further the treatment charge module 331, the energy storage capacitor 3, the treatment discharge module 332, the discharge interface 41 and the defibrillation electrode pads 42 are electrically connected in sequence to form a defibrillation circuit so as to defibrillate a subject to be defibrillated.

It is understood that the treatment discharge module 332 includes a discharge switch (not labeled). The discharge switch is connected between the energy storage capacitor 3 and the discharge interface 41. When the discharge switch is turned on, the energy storage capacitor 3 outputs a discharge voltage to the discharge interface 41 through the discharge switch, and defibrillation discharge is performed through the defibrillation electrode pad 42.

It is understood that the discharge interface 41 may be provided on the circuit board 2 or outside the circuit board 2. In addition, at least part of the discharge interface 41 can also be arranged in the through hole of the rear shell 12, so that the electric connection wire of the defibrillation electrode plate 42 is electrically connected with the discharge interface 41 through the through hole of the rear shell 12, the utility model discloses do not limit the position of the casing of the defibrillation device 100 exposed to the discharge interface 41.

Referring to fig. 5, the discharge interface 41 is located outside the circuit board 2. The discharge interface 41 is close to the therapeutic discharge module 332, and the discharge interface 41 and the energy storage capacitor 3 are arranged along the axial direction of the energy storage capacitor 3.

Specifically, the dimension of the circuit board 2 in the X-axis direction is slightly larger than the dimension of the capacitor in the X-axis direction. The discharging interface 41 and the energy storage capacitor 3 are arranged along the X-axis direction, so that the discharging interface 41 is positioned in a vacant area at one end of the energy storage capacitor 3, the discharging interface 41, the energy storage capacitor 3 and the circuit board 2 are closely arranged, the space waste in the defibrillation device 100 is reduced, and the discharging interface 41 and the circuit board 2 are arranged along the Y-axis direction, so that the overlapping of the discharging interface 41 and the circuit board 2 in the Z-axis direction can be avoided, and the thickness of the defibrillation device 100 is reduced; by placing the discharge interface 41 close to the therapy discharge module 332, the connection path between the discharge interface 41 and the therapy discharge module 332 is short and simple, and the stability and reliability of the defibrillation circuit are improved.

In other embodiments, the discharge interface 41 may be located on the circuit board 2 and located next to the therapeutic discharge module 332 to increase the density of devices on the circuit board 2, increase the mounting stability of the discharge interface 41, and improve the electrical connection stability of the discharge interface 41 and the therapeutic discharge module 332.

Referring to fig. 5, the area of the carrying surface 21 of the circuit board 2 away from the energy storage capacitor 3 is a low voltage area 23. The high voltage device 33 is disposed between the low voltage region 23 and the energy storage capacitor 3 and the low voltage region 23. At least one low voltage device 34 is disposed on the low voltage region 23. It will be appreciated that the voltage at which the high voltage device 33 operates is greater than the voltage at which the low voltage device 34 operates.

Specifically, the high voltage device 33 is provided in the high voltage region 22. The low-voltage area 23, the high-voltage area 22 and the energy storage capacitor 3 are arranged in sequence along the Y-axis direction.

By respectively arranging the high-voltage device 33 and the low-voltage device 34 in the low-voltage area 23 and the high-voltage area 22, compared with the mixed arrangement of the high-voltage device 33 and the low-voltage device 34, the interference of the charging and discharging process of the high-voltage device 33 on the low-voltage device 34 can be avoided, and the interference of the low-voltage device 34 on the charging and discharging of the energy storage capacitor 3 in the working process can be avoided as the low-voltage device 34 is far away from the energy storage capacitor 3.

Referring to fig. 5, the low voltage device 34 includes a main control module 341 and a therapy parameter module (not shown). The therapy parameter module includes at least one parameter sensor 303 for detecting a physiological parameter of the user and transmitting the detected physiological parameter to the main control module 341. The main control module 341 is configured to perform discharge management according to the physiological parameter of the user.

Specifically, the at least one parameter sensor 303 is configured to measure parameters such as impedance of a subject to be defibrillated (e.g., a human body), so that the main control module 341 controls the operation states of the therapy charging module 331 and the therapy discharging module 332 according to the impedance of the human body to complete defibrillation charging and discharging operations.

It can be understood that the therapy parameter module is electrically connected to the main control module 341 and the defibrillation electrode pad 42, and the therapy parameter module detects parameters such as human impedance through the defibrillation electrode pad 42 and transmits the parameters such as human impedance to the main control module 341. The main control module 341 is electrically connected to the therapy charging module 331 and the therapy discharging module 332, and the main control module 341 controls charging and discharging of the therapy charging module 331 and the therapy discharging module 332 according to parameters such as human impedance, so as to perform defibrillation discharging on a human body.

By setting the main control module 341, the treatment parameter module and other low-voltage devices 34, the defibrillation electrode pad 42, the treatment parameter module, the main control module 341, the treatment charging module 331 and the treatment discharging module 332 are electrically connected to form a defibrillation circuit, so as to perform defibrillation discharge treatment on a subject to be defibrillated.

It will be appreciated that the low voltage device 34 further includes a capacitance management module for managing the charging and discharging of the defibrillation circuit, an input/output control module, and the like. The input and output control module is used for controlling the input and output of the electric energy of the defibrillation circuit.

Referring to fig. 2 and 3, the front case 11 or the rear case 12 is provided with a battery compartment 121 for accommodating the battery 5, and the battery compartment 121 is disposed at a position corresponding to the low voltage region 23.

Further, referring to fig. 2 and fig. 3, the low voltage region 23 is disposed on a side of the high voltage region 22 away from the energy storage capacitor 3, and at least one low voltage device 34 is disposed on the low voltage region 23. The distance between the top end of the at least one low voltage device 34 and the circuit board 2 is smaller than the distance between the top end of the high voltage device 33 and the circuit board 2.

Specifically, referring to fig. 2 and 3, when the number of the low voltage devices 34 is multiple, the height of the highest device in the low voltage devices 34 is smaller than the height of the highest device in the high voltage devices 33, that is, the overall height of the low voltage devices 34 is smaller than the overall height of the high voltage devices 33. In other words, a height difference is generated between the low-voltage device 34 and the high-voltage device 33, and the height difference enables the accommodating space 340 to be formed above the low-voltage device 34. Taking the carrying surface 21 of the circuit board 2 facing the rear case 12 as an example, the rear case 12 is recessed toward the carrying surface 21 of the circuit board 2 to form a battery compartment 121. Through setting up battery compartment 121 and locating the position that corresponds to low pressure device 34, battery compartment 121 can be located accommodation space 340 to make battery compartment 121 and low pressure device 34 closely arrange in the Z axle direction, make battery compartment 121 and the device on circuit board 2 thickness as little as possible after the stack in the Z axle direction, and then reduce defibrillation apparatus 100's thickness, reduce the complete machine size.

Further, referring to fig. 2 and 3, the battery compartment 121 may correspond to the low voltage region 23. For example, the low voltage region 23 is rectangular, correspondingly, the battery compartment 121 is rectangular, and the long side of the battery compartment 121 corresponds to the long side of the low voltage region 23; the short side of the battery compartment 121 corresponds to the short side of the low voltage region 23, so as to improve the utilization rate of the battery compartment 121 to the accommodating space 340, and to enable the battery compartment 121 and the devices on the circuit board 2 to be arranged more closely.

Of course, in other embodiments, the carrying surface 21 of the circuit board 2 may face the front case 11, and the battery compartment 121 is disposed on the front case 11.

Referring to fig. 5, the length direction of the battery compartment 121 is taken as the X-axis direction, the width direction of the battery compartment 121 is taken as the Y-axis direction, and the depth direction of the battery compartment 121 is taken as the Z-axis direction for illustration. In the X-axis direction, one end of the battery compartment 121 has an opening, the circuit board 2 is provided with an electrical connection seat 35, pins of the electrical connection seat 35 extend into the battery compartment 121 through the opening, and when the battery 5 is installed in the battery compartment 121, the charging and discharging pins of the battery 5 are abutted to and electrically connected with the pins of the electrical connection seat 35. The main control module 341 and the therapeutic charging module 331 are electrically connected to the battery 5 through the electrical connection socket 35.

Referring to fig. 7, the defibrillation apparatus 100 further includes a battery cover 51. When the battery 5 is installed in the inner cavity of the battery compartment 121, the battery cover 51 covers the battery compartment 121 to fix the battery 5 in the battery compartment 121. In one embodiment, the width of the battery compartment 121 is substantially the same as the width of the battery 5. In the width direction of the battery compartment 121, a clamping groove 52 may be formed on a side surface of the battery 5, a protrusion 122 is formed on an inner wall of the battery compartment 121, and when the battery 5 is placed into the battery compartment 121 along the Z-axis direction, the protrusion 122 enters the clamping groove 52 along the Z-axis. When the battery 5 moves along the X-axis direction until the charging and discharging pins of the battery 5 abut against and are electrically connected to the pins of the electrical connector 35, the protrusion 122 is clamped into the clamping groove 52 along the X-axis, and at this time, the clamping groove 52 limits the battery 5 from moving in the Z-axis direction relative to the battery compartment 121.

A fastening member 123 is disposed on the region of the rear case 12 that covers the battery cover 51, and a fastening member 123 is disposed on the inner surface of the battery cover 51, so that the battery cover 51 is fastened to the rear case 12. Further, in the Z-axis direction, the battery cover 51 and the rear case 12 may be strongly connected by screws.

Further, referring to fig. 8, a protrusion 53 is disposed on an inner surface of the battery cover 51, and when the battery cover 51 covers a region of the rear case 12 where the battery compartment 121 is disposed, the protrusion 53 abuts against an opposite end of the battery 5 where the charging and discharging pins are disposed, so that the charging and discharging pins of the battery 5 are tightly connected to the pins of the electrical connection seat 35, and the electrical connection stability between the battery 5 and the electrical connection seat 35 is improved.

By placing the battery 5 in the space formed by the rear case 12 and the battery cover 51, it is convenient for the maintenance person to replace the battery 5. In addition, since the battery 5 is mounted in the battery chamber 121 of the rear case 12 through the battery cover 51, the battery 5 with various external dimensions can be compatible by designing the battery cover 51 with different shapes. For example, for two batteries 5 of uniform length and width but non-uniform thickness. The battery 5 with large thickness has large storage capacity, and the battery 5 with large thickness can provide longer endurance. Since the length and the width of the two batteries 5 with different capacities are the same, the batteries 5 with different capacities can be placed in the battery compartment 121, and for the battery 5 with large thickness, the battery cover 51 with large depth in the Z-axis direction is only needed. Furthermore, the position of the fastener 123 on the battery cover 51 can be changed according to the actual size of the battery 5, so that the battery cover 51 is connected with the rear shell 12 more tightly.

Referring to fig. 8, the inner surface of the battery cover 51 may further be provided with a locking member 54 for locking with the locking member 123, so that the battery cover 51 is fixed to the rear case 12.

Referring to fig. 9, a first through hole 124 is formed on the bottom wall of the battery compartment 121. The low voltage region 23 is also provided with a USB interface 36. The USB interface 36 is disposed corresponding to the first through hole 124 of the battery compartment 121, and when the battery 5 is disposed in the battery compartment 121, the first through hole 124 is disposed outside the area covered by the battery 5.

Specifically, the USB interface 36 is a Universal Serial Bus (USB) interface. At least a portion of the USB interface 36 may be disposed within the first through hole 124 such that an external connector may be inserted into the USB interface 36.

The number of the first through holes 124 may be plural, and the number of the USB interfaces 36 may be the same as the number of the first through holes 124. In this embodiment, one USB interface 36 is used to export data in the defibrillation apparatus 100 or perform system upgrade on the defibrillation apparatus 100; the other USB interface 36 is used to charge the battery 5.

Referring to fig. 9, by placing the USB port 36 in the battery compartment 121, the risk of high-voltage injury to the operator can be avoided, and the defibrillation apparatus 100 can be easily made waterproof and have a neat appearance. The USB interface 36 is disposed to be offset from the battery 5, so that when the USB interface 36 is used to conduct data or upgrade, the battery 5 can be operated without taking out the battery 5 from the battery compartment 121 by opening the battery cover 51.

Referring to fig. 10, a second through hole 125 is formed on the bottom wall of the battery compartment 121. The low voltage area 23 is also provided with a SIM card interface 37. The SIM card interface 37 is disposed corresponding to the second through hole 125 of the battery compartment 121. When the battery 5 is disposed in the battery compartment 121, the battery 5 covers the second through hole 125.

Specifically, the SIM card interface 37 is a (Subscriber Identity Module) interface, and is also a card slot 52 for installing a SIM card.

At least a portion of the SIM card interface 37 may be disposed within the second through hole 125 such that an operator may install a SIM card in the SIM card interface 37 or remove a SIM card from the SIM card interface 37 through the second through hole 125.

By placing the SIM card interface 37 in the battery compartment 121, not only can the risk of high-voltage injury to the operator be avoided, but also waterproofing can be conveniently achieved and the appearance of the defibrillation apparatus 100 is ensured to be neat; the SIM card interface 37 is positioned in the area covered by the battery 5, and the SIM card is hidden under the battery 5 because the SIM card does not need to be frequently taken down, so that the SIM card has good concealment, and the pressing of the battery 5 can prevent the SIM card from falling off from the SIM card interface 37; the space occupied by the SIM card interface 37 in the X-Y plane may also be reduced, thereby reducing the overall size of the defibrillation apparatus 100.

In other embodiments, the SIM card interface 37 may be located outside the range covered by the battery 5, so that the installation and removal of the SIM card may be achieved without removing the battery 5.

When the defibrillation apparatus 100 is used in a public place, the defibrillation apparatus 100 can only be placed on the ground, and because the upper and lower surfaces of the defibrillation apparatus 100 are generally parallel, it is not easy for an operator to see text and pictures on the operation interface of the defibrillation apparatus 100 or content displayed on the operation interface of the defibrillation apparatus 100 due to the problem of the viewing angle.

Referring to fig. 6, the energy storage capacitor 3 is close to the top end 1a of the rear case 12 and the front case 11. The battery compartment 121 is close to the bottom ends 1b of the rear case 12 and the front case 11. The thickness of the energy storage capacitor 3 in the direction that the rear shell 12 and the front shell 11 are covered is greater than the thickness of the battery compartment 121, the low-voltage device 34 and the circuit board 2 after being superposed, so that when the rear shell 12 is arranged on a horizontal plane, the distance between the front shell 11 and the horizontal plane is gradually reduced from the top end 1a to the bottom end 1 b.

As can be appreciated, the base end 1b and the top end 1a are distributed along the Y-axis direction, and the base end 1b is the end closer to the operator and the top end 1a is the end farther from the operator during normal use of the defibrillation apparatus 100. Specifically, because the diameter of the energy storage capacitor 3 is large, the thickness of the energy storage capacitor 3 in the Z-axis direction is larger than the height of the low-voltage device 34 in the Z-axis direction plus the height of the battery 5 in the Z-axis direction, so that the thickness of the region where the energy storage capacitor 3 is arranged on the rear case 12 is large, and the thickness of the region where the battery 5 is arranged on the rear case 12 is small. By disposing the energy storage capacitor 3 at the top end 1a of the rear case 12 and the front case 11, and disposing the energy storage capacitor 3 at the top end 1b of the rear case 12 and the front case 11, when the rear case 12 of the defibrillation device 100 is flatly placed on the ground, the thickness h1 of the top end 1a of the front case 11 of the defibrillation device 100 is large, and the thickness h2 of the bottom end 1b is small, so that the front case 11 of the defibrillation device 100 is in a natural inclination state, thereby forming an angle convenient for an operator to observe the interface of the front case 11. I.e., in this embodiment, directly from the naturally occurring tilt angle of the thickness of the defibrillation device 100 at different locations. In other embodiments, support feet, or footpads, or brackets may also be provided at one end of the bottom surface of the rear housing 12 of the defibrillation device 100 (e.g., the end near the top end) to provide a natural tilt of the defibrillation device 100 after it is placed on the ground. In addition, the front housing 11 may be designed with an angle of inclination, i.e., one side of the front housing 11 (the top side) is high and one side (the bottom side) is low, and the rear housing 12 is flat, such that the defibrillation apparatus 100 is placed on a horizontal surface to form a natural inclination of the front housing 11.

Through utilizing the thickness difference of energy storage capacitor 3 and battery 5, so that defibrillation apparatus 100's thickness is different, locate energy storage capacitor 3 at the top 1a of backshell 12 and preceding shell 11, locate battery 5 at the bottom 1b of backshell 12 and preceding shell 11, so that defibrillation apparatus 100 forms the fuselage that top 1a thickness is big and bottom 1b thickness is little, when defibrillation apparatus 100's backshell 12 is placed on the horizontal plane, defibrillation apparatus 100's front shell 11 is the natural slope state that top 1a is high, bottom 1b is low, in order to make things convenient for the operator to observe the instruction content on the preceding shell 11 interface.

In public place applications, the operator needs to quickly come to the subject to be defibrillated after having picked up the defibrillation device 100. It is desirable that the defibrillation apparatus 100 be portable for the operator. Currently, only a portion of the defibrillation apparatus 100 can be held by the operator's hands while gripping the housing of the defibrillation apparatus 100, or need to be carried along in an accessory bag, and the defibrillation apparatus 100 is not portable.

Referring to fig. 1 and 2, the defibrillation apparatus 100 includes a handle 6. The handle 6 includes a first handle portion 61 and a second handle portion 62, the first handle portion 61 being provided to the front case 11, and the second handle portion 62 being provided to the rear case 12 and corresponding to the front case 11. When the front and

rear shells

11, 12 are closed, the first and second handle portions 61, 62 in combination form the handle 6 of the defibrillation device 100.

In particular, the handle 6 is integrally formed with the housing of the defibrillation device 100. Further, the handle 6 is generally ring-shaped to facilitate the operator's ability to carry the defibrillation device 100 by hand, increasing the portability of the defibrillation device 100. Further, the handle 6 is provided at the bottom ends of the front case 11 and the rear case 12. Handle 6, circuit board 2 and energy storage capacitor 3 arrange in proper order along the Y axle direction, and handle 6 is little in the ascending thickness of Z axle direction, and handle 6 is located battery 5 and is kept away from the one end of energy storage capacitor 3 to the thickness that makes defibrillation equipment 100 reduces by top to bottom gradually.

By designing a handle 6 integral with the housing on the defibrillation device 100. This handle 6 fuses into a whole with the shell, and half sets up on preceding shell 11, and half sets up on back shell 12, closes to cover the back and forms a handle 6 of accomplishing promptly, and compact structure makes things convenient for the operator to carry when transporting defibrillation equipment 100 during the use, improves defibrillation equipment 100's portability, and the time spent can also make things convenient for defibrillation equipment 100 to hang in the public place.

When the defibrillation apparatus 100 is placed in a public place, as part of routine maintenance, a person is generally scheduled to check the status of the defibrillation apparatus 100 every day, and the operator needs to know whether the status of the defibrillation apparatus 100 is a normal or abnormal status before taking the defibrillation apparatus 100. The status indication of the current defibrillation apparatus 100 is not intuitive enough, and in the case of a dark environment, it is not clear enough or the light spot is small, and it is easily blocked.

Referring to fig. 6, the handle 6 is ring-shaped. An indicator lamp (shielded by a lamp cover, not shown) and a lamp cover 63 provided on the indicator lamp are provided on the inner periphery of the handle 6. The indicator lights are used to indicate the operating status of the defibrillation device 100 by presenting different colors. The outer surface of the lamp housing 63 has a plurality of curved surfaces to enable an operator to see the color of the indicator lamp from a plurality of angles.

Specifically, an indicator light for emitting light is arranged at the middle position of the side close to the top end of the inner ring of the handle 6 of the defibrillation apparatus 100, so that a daily maintainer and an operator of the defibrillation apparatus 100 can observe the state of the defibrillation apparatus 100 conveniently. In particular, the indicator lights indicate the status of the defibrillation device 100 by flashing red or green light intermittently or by emitting light continuously. For example, when the intermittent flashing red light of the indicator light indicates that the indicator light is in an abnormal state, the maintainer is reminded of the need to maintain the defibrillation apparatus 100 in a timely manner; when the indicator light flashes intermittently in a green light indicating that the indicator light is in a normal state, the operator can observe the status of the defibrillation apparatus 100 and defibrillate with the defibrillation apparatus 100. Different states are indicated through lights of different colors, the operation is simple and clear, and the state cannot be indicated clearly due to dim ambient light.

Referring to fig. 6, a lamp cover 63 is disposed above the indicator light for mixing light, so that the light spot of the indicator light is uniform and the light is soft. Further, the lampshade 63 may be disposed at a position where a plurality of curved surfaces are combined, for example, a curved surface at a side of the inner ring of the handle 6 near the top end, and may also extend to the operation interface of the front housing 11; wherein, set up recess 113 on the operation interface of current shell 11, when this recess 113 is used for the installation buckle, lamp shade 63 can extend to in the recess 113 to the colour that the pilot lamp can be seen when the operator is towards the interface of preceding shell 11, so that make things convenient for the multi-angle to observe, can make like this the operator see pilot lamp light at more clear angles. In this arrangement, the light cover 63 may be on the front side of the defibrillation device 100 (the operative side of the front housing 11) and partially extend over the curved surface above. The area of the indicator light cover 63 is as large as possible, so that the observation inconvenience caused by partial shielding is avoided, and the area of the indicator light cover 63 reaches 250mm in the embodiment²The above.

At least part of the indicator light and the lamp shade 63 are arranged on the inner ring of the handle 6, so that the curved surface of the inner ring of the handle 6 is fully utilized, an operator can clearly see the indicator light at more angles, and in addition, the space of the inner ring of the handle 6 is fully utilized, so that the structure of the defibrillation device 100 is more compact, and the miniaturization of the defibrillation device 100 is promoted.

Generally, the defibrillation electrode pads 42 and the defibrillation apparatus 100 are housed together in an accessory bag, and when the defibrillator is used, the electrode pads need to be taken out of the accessory bag and electrically connected to the defibrillation apparatus 100, which takes a lot of time and may delay rescue time.

Referring to fig. 6, the defibrillation apparatus 100 further includes a cover 13 and defibrillation electrode pads 42 disposed on an inner surface of the cover 13. The cover 13 covers the front case 11. The inner surface of the cover 13 is provided with at least one catch 131. The catch 131 serves to catch the defibrillation electrode pads 42 to the inner surface of the cover 13 so that the defibrillation electrode pads 42 are located in the space between the cover 13 and the front case 11.
