Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to an information-identifiable defibrillation electrode. Background Technology

[0002] Automated external defibrillators (AEDs) generally have two defibrillation modes: adult mode and pediatric mode. The difference lies in the energy released during defibrillation. For different patient age groups, rescuers need to first determine the patient's type based on age and weight, and then set the appropriate defibrillator mode accordingly. The energy released during adult and pediatric modes differs. Currently, known technology uses a toggle switch or button on the defibrillator's main unit to switch modes. Rescuers toggle the switch or press the button, and the corresponding indicator light illuminates, indicating successful mode setting. However, this technology has two drawbacks: First, there are three types of defibrillator electrodes: adult electrodes, pediatric electrodes, and combined adult and pediatric electrodes. If an adult electrode is used during an emergency, and the switch is mistakenly activated to pediatric mode, the defibrillator may release pediatric energy on an adult patient. Since pediatric defibrillation energy is lower, this can lead to defibrillation failure. Conversely, if the patient is a child and the system is accidentally switched to adult mode, adult-level defibrillation energy may be applied to the child. Since adult defibrillation energy is higher, this can lead to burns and other injuries after defibrillation. Secondly, installing switches or buttons on the defibrillator requires perforating the outer casing, which compromises the overall structural strength of the defibrillator and increases the difficulty of waterproofing and dustproofing the casing, thus hindering its waterproofing and dustproofing capabilities.

[0003] Chinese Patent Publication No. CN103182147A, entitled "A Method, Defibrillation System, and Defibrillation Electrode for Detecting Attributes of Defibrillation Electrode Patches," describes a device comprising defibrillation electrodes and a defibrillation device host. The defibrillation electrodes include two electrode patches, two electrode connection terminals respectively connecting the two electrode patches, and two detection connection terminals. A detection component for detecting the attributes of the electrode patches is connected between the two detection connection terminals. The defibrillation device host is used to communicate with the detection terminals of the defibrillation electrodes in electrode patch detection mode, send detection signals to the detection component, obtain feedback signals from the detection component, and obtain attribute information of the electrode patch terminals based on the feedback signals. The detection component connected between the electrode patch terminals can be any of the following: a detection resistor; a detection resistor and a detection inductor connected in series; or a detection resistor and a detection capacitor connected in parallel. This patent application requires the defibrillator to store information in the defibrillator to identify electrode patch information through resistance or inductance, thus failing to achieve universality of the electrode patches. Utility Model Content

[0004] In order to overcome the problems existing in the prior art, the purpose of this utility model is to provide an information-identifiable defibrillator electrode that stores the identification information of adult and child modes in a microcontroller with storage function. This eliminates the need for toggle switches or buttons on the defibrillator main unit, avoids accidental operation and damage to the main unit's casing structure, reduces the number of interfaces on the main unit, and can be adapted to defibrillator main units that do not store corresponding resistance or inductance information.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This invention provides an information-identifiable defibrillator electrode without a button switch. The defibrillator main unit automatically identifies and distinguishes the defibrillator electrode type, thereby determining the patient's mode and avoiding the risk of incorrect energy release due to incorrect electrode selection. This invention can also adapt to defibrillator main units that do not store corresponding resistance or inductance information by internally storing information.

[0031] The present invention will now be described in detail with reference to the accompanying drawings.

[0032] An information-identifiable defibrillator electrode is characterized by comprising: a defibrillator circuit board 2, wherein a multi-functional communication interface 3 and a defibrillation discharge interface 4 are connected to the defibrillator circuit board 2, and a single-chip microcomputer control unit is integrated within the defibrillator circuit board 2; one interface of the multi-functional communication interface 3 is connected to the single-chip microcomputer control unit; the single-chip microcomputer control unit has a memory.

[0033] This invention provides an information-identifiable defibrillator electrode without a button switch. The defibrillator main unit can automatically identify and distinguish the defibrillator electrode type, thereby determining the patient mode and avoiding the risk of incorrect energy release due to incorrect electrode selection. This invention can store information in the memory of the microcontroller control unit through a multi-functional communication interface 3, and can be adapted to defibrillator main units that do not store corresponding resistance or inductance information.

[0034] Example 1

[0035] like Figure 1 As shown, the components of adult electrodes and children's electrodes are: injection-molded structural shell 1, defibrillation electrode circuit board 2, multi-functional communication interface 3, defibrillation discharge interface 4.

[0036] The memory of the microcontroller control unit is a Flash memory.

[0037] The microcontroller control unit has an RC oscillator.

[0038] Among them, the injection molded structural shell 1 is used to protect the internal circuit board, and plays a role in waterproofing, dustproofing, high and low voltage electrical isolation inside the defibrillator electrode, and fixing of various interfaces.

[0039] The defibrillator electrode circuit board 2 realizes functions such as detecting the type of defibrillator electrode, identifying the patient mode, indicating the patient mode, and storing the electrode pad production date and expiration date.

[0040] The multi-functional communication interface 3 is used to connect the defibrillation electrodes and the defibrillator main unit to achieve data communication and interaction.

[0041] The defibrillation discharge interface 4 is used to transmit the high-voltage, high-current pulse energy released by the defibrillator main unit to the patient to achieve defibrillation treatment.

[0042] The microcontroller control unit is used to detect whether the push-button switch is triggered, control the on / off state of the indicator lights, store defibrillation electrode information, and communicate data with the host computer.

[0043] like Figure 2The diagram shows the circuit diagram of the microcontroller control unit. Because the defibrillator electrode circuit requires small size and low power consumption, and because the defibrillator electrode is a consumable accessory for the main unit with low hardware cost requirements, the STM32G031 microcontroller was chosen as the controller. It has an internal RC oscillator that provides the operating clock. The reset circuit uses resistor R3 and capacitor C3 for power-on reset. Program download and debugging use the microcontroller's own SWD interface. The microcontroller is powered by the 3.3V supply from the main unit, and capacitors C4 and C2 act as energy storage and filtering capacitors.

[0044] like Figure 3 The diagram shows the multi-functional communication interface 3. The first interface provides 3.3V power to the microcontroller, while the second interface enables data communication, using the microcontroller's serial port to communicate with the defibrillator host. Furthermore, the data communication function also allows for software upgrades of the defibrillator electrodes, writing of production process configuration information, and functional testing of the finished defibrillator electrodes.

[0045] This invention relates to an information-identifiable defibrillator electrode. During production, the electrode type, production date, expiration date, batch number, and UDI code information are written into the Flash memory of the microcontroller control unit via a multi-functional communication interface 3. When the defibrillator electrode is connected to the defibrillator host, this data information can be transmitted to the host via serial communication. The host then determines the validity of the defibrillator electrode, preventing malfunctioning electrodes from affecting defibrillation effectiveness. Furthermore, the host can also transmit this data to a network cloud platform for convenient management and traceability of the defibrillator electrode.

[0046] In this embodiment, the electrode type is encoded using hexadecimal numbers, with adult electrodes being 0xA1 and pediatric electrodes being 0xA2. The high 4 bits of the hexadecimal number represent the defibrillation electrode type configuration parameter, while the low 4 bits represent the specific electrode type.

[0047] Example 2

[0048] like Figure 4 As shown, the present invention provides an information-identifying defibrillation electrode, which, when used, includes the following steps:

[0049] Connect the power supply to power the defibrillation electrode circuit board 2 and the microcontroller control unit.

[0050] It connects to the defibrillator via the multi-function communication interface 3.

[0051] The microcontroller control unit sends electrode status information to the defibrillator through the multi-function communication interface 3. The electrode status information includes the type of defibrillator electrode, the production date of the defibrillator electrode, the expiration date of the defibrillator electrode, the batch number of the defibrillator electrode, and the UDI code of the defibrillator electrode.

[0052] By identifying the type of defibrillator electrode using the defibrillator, operational errors can be avoided due to misuse of electrode types other than those identified by this invention. Furthermore, by recognizing the manufacturing date and expiration date of the defibrillator electrode, it is possible to determine if the defibrillator has expired, preventing electrode failure due to expiration.

[0053] Example 3

[0054] An information-identifiable defibrillator electrode is used in an automated external defibrillator (AED). The defibrillator electrode is connected to the AED main unit via a multi-functional wired communication interface. The data information of the defibrillator electrode (including electrode type, production date, expiration date, batch number, and UDI code) is uploaded to a cloud platform management system through the wireless communication module of the AED main unit, thereby completing the effective management and quality traceability of the defibrillator electrode.

[0055] Unless otherwise specified, the equipment components involved in the above embodiments are all conventional equipment components, and the structural settings, working methods or control methods involved are all conventional settings, working methods or control methods in the art unless otherwise specified.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
