Description

Technical Field

[0001] This invention relates to the field of medical emergency equipment technology, specifically to a portable automated external defibrillator that is convenient for use in emergency situations. Background Technology

[0002] An automated external defibrillator (AED) is a portable and easy-to-use medical device primarily used to deliver an electric shock to patients in emergency situations such as sudden cardiac arrest, in order to restore a normal heartbeat and buy precious emergency time for the patient.

[0003] Existing automated external defibrillators (AEDs) have several shortcomings in emergency situations. Firstly, most AEDs are bulky and inconvenient to carry, making them difficult to quickly access and reach patients in emergency scenarios such as outdoors or on public transport. Secondly, existing AEDs lack angle adjustment mechanisms, resulting in poor viewing angle adaptability during emergency procedures, severely impacting operational efficiency and data accuracy. Due to the lack of angle adjustment, the touchscreen displays are often fixed-angle, making them susceptible to glare from the ground, leading to unclear readings of crucial data such as heart rate and blood oxygen levels. Furthermore, existing AEDs lack real-time monitoring and feedback of the emergency environment and patient condition, preventing adjustments to defibrillation parameters based on actual conditions, thus affecting defibrillation effectiveness. They also fail to promptly alert emergency personnel to take other necessary emergency measures.

[0004] Therefore, it is necessary to invent a portable automated external defibrillator that is easy to use in emergencies to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a portable automated external defibrillator that is convenient for use in emergencies, in order to solve the problems of the present invention being inconvenient to carry, lacking an angle adjustment mechanism, lacking real-time monitoring and feedback of the emergency environment and patient status, being unable to adjust defibrillation parameters according to the actual situation, affecting the defibrillation effect, and also unable to promptly remind emergency personnel to take other necessary emergency measures.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a portable automated external defibrillator (AED) for use in emergencies, comprising a protective shell, a protective cover hinged to the protective shell, and a defibrillator body disposed within the protective shell. The bottom of the protective shell is provided with an adjustable tilt support mechanism, which includes a movable frame, a fixed frame, and a hydraulically driven angle adjustment mechanism. The angle adjustment mechanism achieves angle adjustment of the protective shell by driving a cross-link assembly with a hydraulic rod. The defibrillator body integrates an electrode interface, disposable electrode pads, a touch screen, a power module, and a voice announcer. The inner wall of the protective cover is equipped with a core control module, a monitoring module, and a communication module. The monitoring module includes a heart rate monitoring unit, a blood oxygen saturation monitoring unit, and an electrocardiogram (ECG) monitoring unit, which collects patient physiological data in real time through disposable electrode pads. The communication module includes a wireless communication unit and a positioning unit.

[0007] Preferably, both the protective shell and the protective cover are made of high-strength impact-resistant material, and two latches for locking the protective cover are provided on the front side of the connection between the protective shell and the protective cover.

[0008] Preferably, the interior of the protective shell forms a mounting cavity for accommodating the defibrillator body, and the inner wall of the mounting cavity is lined with a cushioning pad that fits against the outer wall of the defibrillator body.

[0009] Preferably, the front wall of the protective shell is fixed with a U-shaped handle that is easy to hold and carry, and the surface of the handle is provided with anti-slip texture.

[0010] Preferably, the outer side of the protective shell is provided with a retractable shoulder strap for carrying on the shoulder. The retractable shoulder strap includes two nylon straps and an adjustment buckle. One end of each strap is detachably connected to the opposite side walls of the protective shell, and the other end is connected to the adjustment buckle.

[0011] Preferably, the angle adjustment mechanism includes a first movable rod and a second movable rod. The two ends of the first movable rod are slidably engaged with the inner walls of the two sides opposite to the movable frame, and the two ends of the second movable rod are slidably engaged with the inner walls of the two sides opposite to the fixed frame.

[0012] Preferably, the angle adjustment mechanism further includes a first connector, a second connector, two first connecting rods, a first axle pin, a hydraulic rod, two second connecting rods, and a second axle pin. The first connector is fixed to the middle of the first movable rod, and the second connector is fixed to the middle of the second movable rod. The bottom ends of the two first connecting rods are hinged to the first connector, and the two first connecting rods are connected by the first axle pin. The bottom ends of the two second connecting rods are hinged to the second connector, and the top ends of the two second connecting rods are connected by the second axle pin, and the top ends of the two first connecting rods are hinged to the second axle pin. The cylinder end of the hydraulic rod is hinged to the second connector, and the output end of the hydraulic rod is hinged to the first axle pin.

[0013] Preferably, the electrode pad interface is located on one side wall of the defibrillator body, the disposable electrode pad is electrically connected to the electrode pad interface via a wire, and the disposable electrode pad is detachably stored in the inner wall of the protective cover. The touch screen is embedded in the middle front wall of the defibrillator body, and the voice broadcaster is embedded in the front wall of the defibrillator body and located below the touch screen.

[0014] Preferably, the power module includes a rechargeable lithium battery, a charging interface, and a power monitoring unit. The charging interface is located on the outside of one side wall of the defibrillator body and is electrically connected to the rechargeable lithium battery. The power monitoring unit is electrically connected to the rechargeable lithium battery and the core control module, respectively.

[0015] Preferably, the wireless communication unit of the communication module supports Bluetooth connection to mobile terminals, and the positioning unit adopts GPS / BeiDou dual-mode positioning.

[0016] The technical effects and advantages provided by the present invention in the above technical solution are as follows: 1. This invention features a dual-portability design with a handle and a retractable shoulder strap, enabling switching between "hand-carrying" and "shoulder-carrying" modes to meet the transport needs of different emergency scenarios. When transporting in narrow spaces (such as elevators and bus aisles), emergency personnel can carry the defibrillator by hand using the curved handle, flexibly moving through crowded environments. During long-distance transport, the retractable shoulder strap can be pulled out for shoulder-carrying, freeing up the hands and facilitating the simultaneous carrying of other emergency items such as first-aid kits and mobile phones, thereby improving transport efficiency and enabling emergency personnel to carry the defibrillator quickly in different scenarios. 2. This invention uses an angle adjustment mechanism to achieve flexible angle adjustment of the protective shell, effectively adapting to the operating perspective requirements in different emergency environments. The hydraulic drive method has good stability and will not loosen after angle adjustment. Even during the emergency process of chest compressions that generate vibrations, it ensures that emergency personnel can always accurately read the patient data and operating instructions on the display screen, avoiding delays in emergency operations due to perspective issues. 3. This invention achieves real-time monitoring and feedback of the emergency environment and patient status through the coordinated operation of the monitoring module, core control module and voice broadcaster. It can also adjust defibrillation parameters according to the actual situation and promptly remind emergency personnel to take other necessary emergency measures, significantly improving the defibrillation effect and emergency success rate. When the patient's blood oxygen is too low or the heart rate is still unstable even after recovery, the voice broadcaster will promptly broadcast and guide emergency measures, guiding emergency personnel to take comprehensive emergency measures, avoiding reliance on defibrillation alone and ignoring other key emergency steps, and further improving the patient's treatment success rate. 4. This invention constructs a "first aid-medical support" linkage system through the collaboration of the wireless communication unit and the positioning unit of the communication module, saving valuable time for the patient's subsequent treatment. The positioning unit adopts GPS / BeiDou dual-mode positioning, which can accurately obtain the emergency location. The wireless communication unit (4G / 5G or Wi-Fi) can transmit the patient's physiological data (from the monitoring module) and emergency location information to the nearest medical institution or emergency center in real time, allowing medical staff to understand the patient's condition in advance and prepare the receiving equipment (such as defibrillator monitors and emergency medicines), shortening the preparation time for treatment after the patient arrives at the hospital. In addition, the Bluetooth connection function supported by the wireless communication unit can synchronize data during the emergency process (such as defibrillator parameter adjustment records and changes in the patient's vital signs) to the mobile terminal, which is convenient for subsequent medical review and emergency experience summarization, and improves the standardization of the overall emergency system. 5. This invention achieves real-time monitoring and tiered early warning of equipment power levels through the linkage of the power monitoring unit of the power module with the core control module, touch screen, and voice broadcaster. This ensures stable and reliable power supply to the equipment during emergency rescue, preventing interruptions due to power issues. The power monitoring unit collects the remaining power of the rechargeable lithium battery in real time and transmits the power data to the core control module. The core control module displays the corresponding power status on the touch screen based on the power data, promptly reminding emergency personnel of the equipment's power status and preventing interruptions due to sudden power depletion, thus ensuring the continuity and stability of the emergency rescue process.

[0025] This invention provides, for example Figure 1-10 The portable automated external defibrillator (AED) shown is designed for use in emergencies. It includes a protective shell 1, a protective cover 2 hinged to the protective shell 1, and a defibrillator body 5 housed within the protective shell 1. The bottom of the protective shell 1 is provided with an adjustable tilt support mechanism, which includes a movable frame 7, a fixed frame 8, and a hydraulically driven angle adjustment mechanism 11. The angle adjustment mechanism 11 drives a cross-link assembly via a hydraulic rod 1105 to adjust the angle of the protective shell 1. The defibrillator body 5 integrates an electrode interface 12, disposable electrode pads 13, a touch screen display 14, a power module 15, and a voice announcer 16. The inner wall of the protective cover 2 is equipped with a core control module 17, a monitoring module 18, and a communication module 19. The monitoring module 18 includes a heart rate monitoring unit 1801, a blood oxygen saturation monitoring unit 1802, and an electrocardiogram monitoring unit 1803. It collects the patient's physiological data in real time through the disposable electrode pads 13. The communication module 19 includes a wireless communication unit 1901 and a positioning unit 1902.

[0026] Both the protective shell 1 and the protective cover 2 are made of high-strength impact-resistant material. Two latches 3 are provided on the front side of the connection between the protective shell 1 and the protective cover 2 for locking the protective cover 2. The interior of the protective shell 1 forms an installation cavity to accommodate the defibrillator body 5, and the inner wall of the installation cavity is lined with a cushioning pad that fits against the outer wall of the defibrillator body 5. A U-shaped handle 4 is fixed to the front wall of the protective shell 1 for easy hand handling and carrying, and the surface of the handle 4 is provided with anti-slip texture. The outer side of the protective shell 1 is provided with a retractable shoulder strap 6 for carrying on the shoulder. The retractable shoulder strap 6 includes two nylon straps and an adjustment buckle. One end of each strap is detachably connected to the opposite side walls of the protective shell 1, and the other end is connected to the adjustment buckle.

[0027] In this embodiment, the handle 4 facilitates hand-held transport of the equipment, the anti-slip texture increases friction when held to prevent slipping, and the telescopic shoulder strap 6 provides a shoulder-carrying method, the length of which can be adjusted as needed to facilitate carrying the equipment in different scenarios.

[0028] The angle adjustment mechanism 11 includes a first movable rod 9 and a second movable rod 10. The two ends of the first movable rod 9 are slidably engaged with the inner walls of the opposite sides of the movable frame 7, and the two ends of the second movable rod 10 are slidably engaged with the inner walls of the opposite sides of the fixed frame 8. The angle adjustment mechanism 11 also includes a first connecting member 1101, a second connecting member 1102, two first connecting rods 1103, a first axle pin 1104, a hydraulic rod 1105, two second connecting rods 1106, and a second axle pin 1107. The first connecting member 1101 is fixedly connected to the middle of the first movable rod 9, and the second connecting member 1102... Fixed to the middle of the movable rod 10, the bottom ends of the two connecting rods 1103 are hinged to the connecting piece 1101, the two connecting rods 1103 are connected by the shaft pin 1104, the bottom ends of the two connecting rods 1106 are hinged to the connecting piece 1102, the top ends of the two connecting rods 1106 are connected by the shaft pin 1107, and the top ends of the two connecting rods 1103 are hinged to the shaft pin 1107. The cylinder end of the hydraulic rod 1105 is hinged to the connecting piece 1102, and the output end of the hydraulic rod 1105 is hinged to the shaft pin 1104.

[0029] In this embodiment, the extension and retraction of the hydraulic rod 1105 drives the shaft pin 1104 to move, thereby causing the connecting rod 1103 and connecting rod 2106 to change angle. Since the movable rod 19 and movable rod 210 slide in the movable frame 7 and fixed frame 8 respectively, the angle adjustment function is realized. This mechanism can be used to adjust the angle of the defibrillator body 5 or other related components to meet different usage scenarios and operation requirements, making it easier for users to observe the data displayed on the touch screen 14 more intuitively, and improving the flexibility and convenience of use.

[0030] Electrode interface 12 is located on one side wall of the defibrillator body 5. Disposable electrode 13 is electrically connected to electrode interface 12 via wires and can be detachably stored in the inner wall of the protective cover 2. Touch screen 14 is embedded in the middle front wall of the defibrillator body 5. Voice broadcaster 16 is embedded in the front wall of the defibrillator body 5 and located below the touch screen 14. Power module 15 includes a rechargeable lithium battery, a charging interface and a power monitoring unit. The charging interface is located on the outside of one side wall of the defibrillator body 5 and is electrically connected to the rechargeable lithium battery. The power monitoring unit is electrically connected to the rechargeable lithium battery and the core control module 17 respectively. The wireless communication unit 1901 of the communication module 19 supports Bluetooth connection to mobile terminals. The positioning unit 1902 adopts GPS / BeiDou dual-mode positioning.

[0031] In this embodiment, the electrode interface 12 and disposable electrode 13 are used to transmit the defibrillator's electrical energy to the patient's body for defibrillation treatment. The touch screen 14 provides an intuitive operating interface, allowing users to perform various settings and operations on the defibrillator via touch, such as selecting defibrillation modes and adjusting parameters. The voice broadcaster 16 provides voice prompts and guidance during operation, facilitating correct operation of the device without visual assistance, especially in emergency situations, improving operational efficiency and accuracy. The power module 15 provides power support for the defibrillator, and the rechargeable lithium battery is reusable. The charging interface facilitates battery charging, and the power monitoring unit monitors the battery level in real time and feeds the information back to the core control module 17 to remind the user to charge in a timely manner, ensuring normal device operation. Meanwhile, the wireless communication unit 1901 of the communication module 19 supports Bluetooth connection to mobile terminals, enabling data transmission and remote control between the device and mobile devices such as mobile phones. The positioning unit 1902 uses GPS / BeiDou dual-mode positioning, which can accurately obtain the device's location information, facilitating rapid location of the device in emergency rescue and other scenarios.

[0032] Working principle of this invention: Refer to the instruction manual appendix Figure 1-10 When using this invention, first, place the protective shell 1 with its bottom facing down on a flat surface or a stable plane next to the patient. If it is necessary to adjust the operating angle, activate the start button of the hydraulically driven angle adjustment mechanism 11 inside the protective shell 1. The hydraulic rod 1105 extends and retracts, pushing the shaft pin 1104 to move, which in turn causes the connecting rod 1103 and connecting rod 2106 to change their angles. The movable rod 19 and movable rod 210 slide in the movable frame 7 and the fixed frame 8 respectively, so as to realize the adjustable tilt angle of the protective shell 1 (0°-60°) and ensure that the touch screen 14 is facing the operator's line of sight. Next, remove the disposable electrode pads 13 from the inner wall of the protective cover 2, peel off the adhesive protective film on the back, insert the electrode pad wires into the electrode pad interface 12 on the side wall of the defibrillator body 5, and attach the electrode pads to the patient's chest (usually the upper right chest wall and the lower left chest wall) as shown in the figure. The core control module 17 on the inner wall of the protective cover 2 automatically activates the monitoring module 18, and collects the patient's physiological data through the disposable electrode pads 13. The heart rate monitoring unit 1801 detects the electrocardiogram signal in real time and calculates the heart rate. The blood oxygen saturation monitoring unit 1802 measures the blood oxygen value through the principle of infrared light reflection. The electrocardiogram monitoring unit 1803 generates ECG waveforms and analyzes the type of arrhythmia. The data is displayed synchronously on the touch screen 14, and the monitoring results are prompted by voice through the voice broadcaster 16. Then, the core control module 17 automatically analyzes the electrocardiogram data to determine whether defibrillation is needed. If defibrillation is needed, the voice broadcaster 16 issues a command; if defibrillation is not needed, the device continues to monitor and prompts to continue cardiopulmonary resuscitation (CPR). At the same time, through the wireless communication unit 1901 of the communication module 19, the Bluetooth function is enabled and connected to the mobile devices (such as mobile phones and tablets) of emergency personnel or hospital terminals to transmit patient electrocardiogram, heart rate, blood oxygen and other data to the remote medical platform in real time. The positioning unit 1902 enables GPS / BeiDou dual-mode positioning and sends the device's current location information to the emergency dispatch center. Through the above steps, this automated external defibrillator can provide full-process emergency support from rapid deployment and accurate monitoring to efficient defibrillation. It also integrates intelligent communication and positioning functions, significantly improving the success rate of rescue in emergency situations.

[0033] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
