[0056] An AED (Automated External Defibrillator) is a portable medical device designed to resuscitate patients experiencing cardiac arrest. It restores a normal heart rhythm by delivering an electric shock. With the widespread adoption of AEDs in public and emergency medical services, their effectiveness in treating sudden cardiac arrest has been significantly validated.

[0057] In related technologies, some emergency rescue devices include a cardiopulmonary resuscitation (CPR) mechanism and a defibrillator (automated external defibrillator). The defibrillator is fixed to the housing of the emergency rescue device, while the CPR mechanism is movably housed within the housing. The CPR mechanism is used to perform CPR on the patient, while the defibrillator is used to defibrillate the patient. The two work together to significantly improve the patient's survival rate.

[0058] However, the cardiopulmonary resuscitation (CPR) mechanism is prone to moving or detaching within the casing of the emergency rescue device. This application provides an emergency rescue device that solves the problem of the CPR mechanism easily moving or detaching within the casing of the emergency rescue device.

[0059] Figure 1 This is a schematic diagram of the overall structure of an emergency rescue device provided in one embodiment of this application; Figure 2 yes Figure 1 A schematic diagram of the emergency rescue device after removing the cover 130; Figure 3 yes Figure 1 A schematic diagram of the emergency medical device after removing the cover 130 and the defibrillator assembly 200.

[0060] Reference Figure 1As shown in the illustration, this application provides an emergency rescue device, including a housing 100, a defibrillator 200, and a cardiopulmonary resuscitation (CPR) mechanism 300. The defibrillator 200 is disposed within the housing 100 and is used to defibrillate a patient. The CPR mechanism 300 is movably placed within the housing 100 and can be selectively strapped to the patient's chest for CPR. This emergency rescue device integrates the defibrillator 200 and the CPR mechanism 300, enabling coordinated operation of both and achieving sequential coordination between CPR and external defibrillation, significantly improving the patient resuscitation success rate.

[0061] In some examples, housing 100 includes an upper housing 110, a lower housing 120, and a cover 130. The upper housing 110 is fitted onto the lower housing 120 and fixed together by snaps or screws. The upper housing 110 and lower housing 120 enclose a receiving space for components such as a control panel and power supply. The upper housing 110 has a placement space for accommodating the defibrillator 200, which is recessed from the surface of the upper housing 110 and protrudes into the receiving space. The cover 130 selectively covers the upper housing 110. The cardiopulmonary resuscitation (CPR) device 300 is placed in this placement space. The defibrillator 200 is disposed between the upper housing 110 and the lower housing 120, and electrode patches of the defibrillator 200 are placed between the cover 130 and the upper housing 110. The electrode patches are used to attach to the patient's chest skin for defibrillation.

[0062] In addition, an interactive display screen is fixedly installed on the upper housing 110. This interactive display screen is electrically connected to the control systems of the defibrillator 200 and the cardiopulmonary resuscitation (CPR) mechanism 300, respectively. It can display the working status of the defibrillator 200 and the CPR mechanism 300, and can display compression parameters in real time and provide standardized operating procedure guidance, significantly improving the user's ease of operation and accuracy. It should be noted that the control systems and control methods of the defibrillator 200 and the CPR mechanism 300 are existing technologies, and this application does not involve improvements to the control components; therefore, they will not be described in detail here. Furthermore, the upper housing 110 is equipped with multiple buttons for controlling the operation of the defibrillator 200 and the CPR mechanism 300; these will not be described in detail here. It should also be noted that the defibrillator 200 is existing technology, with components and corresponding connections; these will not be described in detail here.

[0063] For example, in order to improve the integration of the defibrillator 200 with the cardiopulmonary resuscitation (CPR) mechanism 300, the defibrillator 200 and the CPR mechanism 300 share a power supply.

[0064] Figure 4 This is a first schematic diagram of the lower housing 120 provided in an embodiment of this application; Figure 5 yes Figure 4Another angled schematic diagram of the lower housing 120. (Refer to...) Figure 4 and Figure 5 As shown, the emergency rescue device also includes a battery 500, which is inserted into the lower housing 120 and electrically connected to the defibrillator 200 and the cardiopulmonary resuscitation mechanism 300, respectively, to supply power to both. The emergency rescue device includes a battery fixing assembly, which includes a first latching portion 121 and a second latching portion 122. The first latching portion 121 and the second latching portion 122 are spaced apart within the housing 100 and close to the side wall of the housing 100.

[0065] For example, the lower housing 120 has an opening on its side. A first latching portion 121 and a second latching portion 122 are spaced apart within the lower housing 120 at positions corresponding to the opening. Both the first latching portion 121 and the second latching portion 122 can be hollow annular structures or U-shaped. The inner sides of the first latching portion 121 and the second latching portion 122 respectively conform to the outer shape of the battery 500 to limit the battery 500. The battery 500 extends from the side wall of the lower housing 120 into the first latching portion 121 and the second latching portion 122, which limit and fix the battery 500 within the lower housing 120.

[0066] For example, the first locking portion includes a first limiting portion, a second limiting portion, and a third limiting portion connected in sequence, forming an overall U-shape, with the battery being limited inside the first limiting portion, the second limiting portion, and the third limiting portion. The end of the first limiting portion away from the second limiting portion is fixedly connected to the lower housing by a screw, and the end of the third limiting portion away from the second limiting portion is fixedly connected to the lower housing by a screw.

[0067] In addition, to facilitate battery replacement, the first latching portion 121 is provided with a connecting terminal 123. This connecting terminal 123 matches the terminals of the battery 500, allowing the battery 500 to be inserted into the connecting terminal 123 for easy battery replacement. For example, the connecting terminal 123 can be fixed to the first latching portion 121 by adhesive, screw connection, or latching. Specifically, the connecting terminal can be located on any one of the first limiting portion, the second limiting portion, and the third limiting portion, as long as it allows for electrical connection to the battery. Both the defibrillator assembly 200 and the cardiopulmonary resuscitation mechanism 300 are electrically connected to the battery 500 via this connecting terminal 123. For example, the first latching portion 121 and the second latching portion 122 can be integrally injection molded with the lower housing 120, or they can be fixedly connected by screws. The connecting terminal 123 can be configured as a cable connector.

[0068] In some examples, the sides of the first limiting part, the second limiting part, and the third limiting part are provided with cross-arranged transverse reinforcing ribs and longitudinal reinforcing ribs to enhance their strength and prevent damage to the first limiting part, the second limiting part, or the third limiting part due to excessive weight or shaking of the battery 500.

[0069] In some examples, the battery 500 has a battery cover at its end, which closes the opening of the lower housing 120. The battery 500 and the battery cover are bonded together using VHB double-sided adhesive, further enhancing the stability of the battery 500. A large waterproof gasket is provided on the battery cover, located between the lower housing 120 and the battery cover, effectively preventing moisture intrusion. In some examples, the battery cover can be securely fixed to the lower housing 120 with screws, ensuring that the battery 500 is firmly mounted on the lower housing 120.

[0070] Figure 6 This is a schematic diagram of the structure of the cover 130 provided in one embodiment of this application.

[0071] Reference Figure 1 and Figure 6 As shown, in some examples, one end of the cover 130 is hinged to the upper housing 110 via a shaft, and the other end is engaged with the corresponding locking groove of the upper housing 110 via a double-stage locking mechanism. In this application, even if the cardiopulmonary resuscitation mechanism 300 is not positioned correctly or the cable is not properly wound in an emergency, the cover 130 can still be fastened to the upper housing 110 via the double-stage locking mechanism, greatly improving the reliability and stability of the emergency equipment in emergency situations and providing a safer and more efficient guarantee for emergency operations.

[0072] For example, the emergency rescue device includes a double-stage latch 400. The double-stage latch 400 has a hinge portion 430, a primary latch portion 410 and a secondary latch portion 420 arranged sequentially at intervals on the hinge portion 430. One end of the hinge portion 430 is hinged to the upper housing 110. When the cover 130 is fastened to the upper housing 110, at least one of the primary latch portion 410 and the secondary latch portion 420 is engaged with the upper housing 110. Specifically, when the cardiopulmonary resuscitation mechanism 300 is in place and the cable is correctly wound, the cover 130 can be tightly fastened to the upper housing 110. At this time, the secondary latch portion 420 is engaged with the latching groove of the upper housing 110. When the cardiopulmonary resuscitation mechanism 300 is not in place or the cable is not correctly wound, the cover 130 cannot be tightly fastened to the upper housing 110. At this time, the primary latch portion 410 is engaged with the latching groove of the upper housing 110.

[0073] In some examples, multiple double-stage latches 400 are provided, with the multiple double-stage latches 400 being spaced apart along the outer edge of the cover 130. For example, one double-stage latch 400 may be provided on each of the three sides of the cover 130 excluding the hinge side.

[0074] For example, the hinge portion 430 can be configured as a hinge post or a hinge plate, and both the primary snap-fit ​​portion and the secondary snap-fit ​​portion can be configured as snap-fit ​​protrusions for snapping with the upper housing 110.

[0075] Reference Figure 2 and Figure 3 As shown, in some examples, the emergency medical device also includes a limiting member 600 for limiting the cardiopulmonary resuscitation (CPR) mechanism 300 within the placement space of the upper housing 110. Exemplarily, both ends of the limiting member 600 are movably connected to the upper housing 110 via snap-fit ​​connections and are located above the CPR mechanism 300, thereby limiting the CPR mechanism 300 within the housing 100.

[0076] In other examples, one end of the limiting member 600 is fixedly connected to the housing 100, while the other end is selectively movablely connected to the housing 100. For example, the limiting member 600 is configured as a flexible member, with one end fixed to the upper housing 110 by screws and the other end movably connected to the upper housing 110 by a snap-fit. Exemplarily, the limiting member 600 is configured as a flexible strap, with one end fixed to the upper housing 110 by a tapered pin and sheet metal components, and the other end movably connected to the upper housing 110 by Velcro or a buckle, achieving rapid and secure fixation of the cardiopulmonary resuscitation mechanism 300 and its cables. Exemplarily, the flexible strap is configured as an elastic strap or a nylon elastic strap. The conical needle is installed in the upper housing 110. The conical needle can be inserted into the flexible limiting member 600. The connection between the conical needle and the limiting member 600 is reinforced by sheet metal pressing technology, which can effectively prevent the limiting member 600 from being accidentally pulled out under strong pulling, thereby significantly enhancing the fixation effect of the cardiopulmonary resuscitation mechanism 300 and ensuring the safety and reliability of the emergency rescue process.

[0077] In other examples, at least two flexible straps are provided, with the two flexible straps intersecting on the upper housing 110 of the housing 100.

[0078] Figure 7 This is a schematic diagram of the structure of a cardiopulmonary resuscitation mechanism 300 provided in one embodiment of this application; Figure 8 yes Figure 7 A schematic diagram of the cardiopulmonary resuscitation device 300 after the cables have been removed; Figure 9 yes Figure 7 A schematic diagram of the cardiopulmonary resuscitation (CPR) device 300 with the protective cover removed; Figure 10 A schematic diagram of the structure 310 of the frame of the cardiopulmonary resuscitation mechanism 300 provided in one embodiment of this application; Figure 11 yes Figure 7 A top view of a cardiopulmonary resuscitation (CPR) unit 300 in China; Figure 12 yes Figure 11Cross-sectional view of a cardiopulmonary resuscitation (CPR) unit in China, viewed from section 300A-A. Figure 13 yes Figure 7 Another top view of the cardiopulmonary resuscitation facility 300 in the center; Figure 14 yes Figure 13 A sectional view of the cardiopulmonary resuscitation facility observed in section 300B-B.

[0079] Reference Figures 7 to 14 As shown, the cardiopulmonary resuscitation (CPR) mechanism 300 includes a frame 310, a compression member 320, a connecting strap, a drive assembly 340, and at least two support arms 350. The two support arms 350 are hinged to the frame 310 and are arranged opposite to each other. The compression member 320 is fixedly connected to the frame 310 and is used to perform chest compressions on the patient. The two ends of the connecting strap wrap around the patient's back and are routed around the two support arms 350, so that the compression member abuts against the patient's chest.

[0080] The drive assembly 340 is connected to the frame 310. When the drive assembly 340 is activated, it drives the two support arms 350 to periodically swing up and down, thereby causing the compression member 320 to periodically press against the patient's chest, mimicking the action of manual cardiopulmonary resuscitation (CPR). Because the drive assembly 340 enables the compression member 320 to periodically press against the patient, consistent action is ensured, guaranteeing standard and effective CPR, thus improving patient survival rates. For example, the compression member 320 is configured with a circular structure to ensure accurate application of pressure to the patient's heart. The connecting strap can be configured as a nylon connecting strap.

[0081] Reference Figure 12 and Figure 13 As shown, the drive assembly 340 includes a drive motor 341, a reducer 342, a drive member 343, and at least two transmission members 344. The drive motor 341 is mounted on the frame 310. The drive motor 341 drives the support arm 350 to swing up and down through the reducer 342, drive member 343, and transmission members 344 connected in sequence, so that the pressing component 320 periodically presses the patient's chest. Specifically, the reducer 342 is mounted on the frame 310, the output end of the drive motor 341 is connected to the input end of the reducer 342, and the output end of the reducer 342 is connected to the drive member 343.

[0082] For example, refer to Figure 8 As shown, the upper end of the driving component 343 is provided with an undulating track. One end of the transmission component 344, which is connected to the support arm 350, abuts against the undulating track. When the drive motor 341 drives the driving component 343 to rotate through the reducer 342, one end of the transmission component 344 swings up and down with the undulation of the track, while the other end drives the support arm 350 to swing up and down. Figure 12As shown, during the rotation of the drive component 343, when the transmission component 344 is at its lowest position on the undulating track, the support arm 350 tilts downwards. At this time, the space between the connecting belt and the pressing component 320 is at its maximum, and the pressing component 320 is not pressing on the patient. Figure 14 As shown, during the rotation of the drive component 343, when the transmission component 344 is at the highest point of the undulating track, the undulating track pushes the support arm 350 to swing upward. At this time, the space between the connecting belt and the pressing component 320 is minimized. The pressing is not only performed on the patient, but also repeated, imitating the manual chest compressions performed on the patient to perform cardiopulmonary resuscitation.

[0083] In some examples, in order to reduce the friction between the transmission component 344 and the driving component 343, a roller is provided at the end of the transmission component 344 that contacts the driving component 343, thereby changing the static friction between the transmission component 344 and the driving component 343 into dynamic friction, which serves to protect the transmission component 344 and the driving component 343.

[0084] Continue to refer to Figure 7 As shown, the cardiopulmonary resuscitation (CPR) mechanism 300 also includes an upper protective shell 360 and a lower protective shell 370. The upper protective shell 360 is fixedly connected to the frame 310 and covers the drive motor 341 to protect it. The lower protective shell 370 is also fixedly connected to the frame 310. The upper protective shell 360 and the lower protective shell 370 together form an accommodating space within which the drive motor 341, the reducer 342, and the drive component 343 are located. The upper protective shell 360 and the lower protective shell 370 protect the drive motor 341, the reducer 342, and the drive component 343 from damage.

[0085] Additionally, in some examples, such as Figure 9 As shown, the cardiopulmonary resuscitation (CPR) device also includes a controller housing 380 and a cooling fan 330. The controller housing 380 is disposed on the upper surface of the upper protective shell 360, and the controller is disposed in the space enclosed by the controller housing 380 and the upper protective shell 360. The cooling fan 330 is disposed inside the controller housing 380 for dissipating heat from the controller. For example, the controller housing 380 has exhaust vents on its side for heat dissipation.
