Description

Technical Field

[0001] This utility model relates to the field of medical and nursing device technology, specifically to a portable medical electrocardiogram monitor. Background Technology

[0002] Medical electrocardiogram (ECG) monitors are medical devices widely used in clinical monitoring and diagnosis. Currently, medical ECG monitors are mainly divided into two categories: one is desktop medical monitors used in hospital wards or operating rooms, which have monitoring functions such as ECG, blood oxygen, and blood pressure to monitor the vital signs of patients in the clinical treatment stage (hospitalization or surgery); the other is portable medical monitors used in home settings, which record ECG signals through single-lead or three-lead connections to achieve the monitoring function for users.

[0003] Desktop medical monitors are too bulky for home use. Portable monitors on the market often resemble the portable ECG monitor disclosed in Chinese utility model patent document (CN210249831U), with a central display screen and operation buttons concentrated on one side. While this design is unobstructed when the patient is healthy, it can easily lead to accidental button presses and delayed distress signals if the patient falls or experiences other abnormalities. Utility Model Content

[0004] This invention provides a portable medical electrocardiogram (ECG) monitor to solve the problem of easy misoperation of existing portable ECG monitors in emergency situations.

[0005] To solve the above-mentioned technical problems, the present invention provides a portable medical electrocardiogram (ECG) monitor, which includes an ECG acquisition device. The portable medical ECG monitor includes a housing, a circuit board, and a data interface. The housing includes a first shell layer, a second shell layer, and a third shell layer connected sequentially along the thickness direction. The first shell layer is provided with an emergency button, and the second shell layer and the third shell layer are connected to form a chamber capable of accommodating a battery.

[0006] The circuit board is located between the first shell layer and the second shell layer along the thickness direction, and is provided with a GPS module and / or a buzzer, wherein the GPS module and the buzzer are configured to activate the GPS module and / or the buzzer when the emergency button is pressed; the data interface is located on the circuit board and is used to connect to the lead wire.

[0007] The beneficial effects of the technical solution provided by this utility model compared to the prior art are as follows:

[0008] By configuring a GPS module and a buzzer, a single-button emergency call can locate the patient via GPS and activate the alarm. GPS location allows medical staff or family members to track the patient's location, while the buzzer attracts attention from those nearby, improving emergency response efficiency. Furthermore, the recessed emergency button on the first shell reduces accidental operation under normal conditions and meets the needs of emergency procedures. Even when the patient is disoriented, they can blindly activate the button, avoiding interference from the display screen and other buttons.

[0009] Furthermore, the aforementioned circuit board includes an ECG acquisition unit, enabling it to capture bioelectrical signals and perform amplification, filtering, and analog-to-digital conversion to obtain the patient's ECG status when the data interface is connected to the lead wires. Compared to current portable ECG monitors that require a display screen and multiple buttons for operation, the integrated design of the aforementioned casing achieves device miniaturization while maintaining functional integrity.

[0010] In some implementations, the cavity is further provided with a SIM card slot connected to the circuit board, wherein the circuit board also includes a 4G communication module.

[0011] The above technical solution enables remote data transmission and real-time monitoring. Specifically, compared to current ECG monitors that require a mobile phone to transmit data to a remote server, the above solution allows the device to access mobile networks via a SIM card, enabling direct data transmission to a remote server.

[0012] In some implementations, the circuit board is also equipped with an accelerometer. The accelerometer is used to monitor the patient's movement and detect potential falls.

[0013] In some implementations, the data interface can also be connected to a power cord. By adopting the above technical solution and setting the data interface to be multifunctional (e.g., compatible with Type-C protocol and supporting 5V / 2A fast charging), space utilization can be improved. This design, which reuses the connection cable and power cord interface, also avoids incorrect plugging by elderly patients.

[0014] Furthermore, the cavity formed by the connection of the second shell and the third shell can accommodate a lithium-ion battery, wherein when the data interface is connected to an external power supply, it can provide power to the lithium-ion battery to improve the device's battery life.

[0015] In some implementations, the surface area of ​​the emergency button is greater than or equal to one-third of the surface area of ​​the first shell layer. An emergency button with a large button area and a recessed design can increase the trigger range for the patient in an emergency.

[0016] In some embodiments, the cavity also includes an SD card slot connected to the circuit board, allowing an SD card to be inserted for storing local data. Furthermore, the second shell layer is provided with a rubber sleeve, which is fitted into the second shell layer and covers the opening of the SD card slot. By employing the above technical solution, the rubber sleeve reduces the intrusion of dust, moisture, etc., into the SD card slot.

[0017] In some embodiments, the circuit board is further provided with multiple LEDs, wherein the first shell layer is provided with multiple light-transmitting films corresponding to the LEDs. Further, a power display push block is slidably provided between the first shell layer and the second shell layer, and the power display push block is electrically connected to the multiple LEDs.

[0018] By adopting the above technical solution, the combination of LED lights and light-transmitting film enables the visual display of the device status. For example, pushing the power display pusher can display the current remaining power, so that users can understand the remaining power status in a timely manner. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0033] For ease of subsequent description, before describing the specific structure of the portable medical electrocardiogram monitor, this application will first combine... Figure 1 Define the thickness direction as Figure 1 As shown in the Z direction. It is worth noting that in the specification and claims of this application, "and / or" means at least one of the connected objects, and the character " / " indicates that the preceding and following related objects are in an "or" relationship.

[0034] See Figures 1 to 4 As shown, Figure 1 This application provides a three-dimensional structural schematic diagram of an embodiment of a portable medical electrocardiogram monitor. Figure 1 ; Figure 2 This illustration shows an internal structure diagram of an embodiment of a portable medical electrocardiogram monitor provided in this application; Figure 3 This application provides a structural block diagram illustrating an embodiment of a portable medical electrocardiogram monitor. Figure 4 This application provides a three-dimensional structural schematic diagram of an embodiment of a portable medical electrocardiogram monitor. Figure 2 .

[0035] In some embodiments, the portable medical electrocardiogram monitor includes an electrocardiogram acquisition unit 50, a housing 10, a circuit board 20, and a data interface 30. The housing 10 includes a first shell layer 11, a second shell layer 12, and a third shell layer 13 connected sequentially along the thickness direction. The first shell layer 11 is provided with an emergency button 110, and the second shell layer 12 and the third shell layer 13 are connected to form a chamber 14 capable of accommodating a battery 40.

[0036] The circuit board 20 is located between the first shell layer 11 and the second shell layer 12 along the thickness direction, and is provided with a GPS module 21 and / or a buzzer 22. The GPS module 21 and the buzzer 22 are configured to be activated when the emergency button 110 is pressed. The data interface 30 is located on the circuit board 20 and is used to connect to the lead wire.

[0037] In this embodiment, the configuration of GPS module 21 and buzzer 22 enables one-button triggering of the emergency button to locate the patient via GPS and activate the buzzer alarm function. For example, combined with... Figure 3 As shown, when GPS module 21 is set, it can be connected to the microcontroller via a serial port and obtain location information through the GPS antenna. GPS positioning facilitates tracking of the patient's location by medical staff or relatives; the buzzer 22 alarm attracts the attention of people near the patient, thereby improving emergency response efficiency. Furthermore, as... Figure 1 As shown, the emergency button 110 is recessed in the first shell layer 11. While reducing misoperation in normal state, it also meets the needs of human emergency operation. Patients can blindly trigger the emergency button 110 when their consciousness is impaired, avoiding interference from the display screen and other operation buttons. At the same time, eliminating the display screen and other components can further reduce the overall size of the device and improve its convenience.

[0038] Furthermore, the aforementioned circuit board 20 is equipped with an ECG acquisition unit 50, enabling the ECG acquisition unit 50 to capture bioelectrical signals through the data interface 30 when the data interface 30 is connected to the lead wires, and to perform amplification, filtering, analog-to-digital conversion, etc., to obtain the patient's ECG status. Compared to current portable ECG monitors that have a display screen and multiple buttons for operation, the integrated design of the aforementioned housing 10 can achieve device miniaturization while ensuring functional integrity.

[0039] In some implementation schemes, combined Figure 3As shown, the data interface 30 can also be connected to a power cord. In this embodiment, the data interface 30 is configured as a multi-functional interface (e.g., compatible with Type-C protocol and supporting 5V / 2A fast charging), which can improve space utilization. This design of multiplexing the lead wire and power cord interface can also prevent elderly patients from making incorrect connections.

[0040] In some applications, when the portable medical monitor is in monitoring mode, the lead wires are connected to the human body and the data interface 30 respectively to obtain electrocardiogram signals. When the portable medical monitor is in charging mode, the data interface 30 is connected to an external power supply to charge the battery 40. For example... Figure 3 As shown, a power management circuit is included to enable circuit connectivity between the various components. Exemplarily, the microcontroller acts as the main control module of the circuit board, communicating with the ECG acquisition unit 50, the SD card, and the accelerometer 24 described below via SPI (Serial Peripheral Interface). The ECG acquisition unit 50 includes analog and digital circuits for converting the bioelectrical signals generated by the heart into electrical signals that can be further analyzed and processed. Conventional techniques can be employed, and this application does not limit the scope of the application.

[0041] In some embodiments, the circuit board 20 is further provided with a plurality of LEDs 111, wherein the first shell layer 11 is provided with a plurality of light-transmitting films corresponding to the LEDs 111. Exemplarily, one or more of the LEDs 111 can be electrically connected to the 4G communication module 23 to display the 4G network signal strength.

[0042] In some implementations, the circuit board 20 is also equipped with an accelerometer 24. The accelerometer 24 is used to monitor the patient's movement status and detect possible falls. For example, existing acceleration calculation algorithms can be used to monitor whether elderly people have fallen, such as the elderly fall detection and monitoring system disclosed in Chinese invention patent document (CN105796112A), to exclude data from normal behavior, detect and locate fall events, making the above-mentioned electrocardiogram monitoring equipment more suitable for use by older patients.

[0043] See Figures 5 to 6 As shown, Figure 5 A top view of an embodiment of a portable medical electrocardiogram monitor provided in this application is shown; Figure 6 This paper shows a three-dimensional structural schematic diagram of an embodiment of the emergency button 110 of a portable medical electrocardiogram monitor provided in this application.

[0044] In some implementations, the surface area of ​​the emergency button 110 is greater than or equal to one-third of the surface area of ​​the first shell layer 11. For example... Figure 5As shown, the area where the heart is located is the central pressing zone. The emergency button 110, with its large button area and recessed design, increases the trigger range for patients in emergency situations. For example, the circuit board has multiple protrusions 112 (such as...). Figure 2 As shown), the inner side of the emergency button 110 has a cross-shaped protrusion structure corresponding to the protrusion 112. This application does not limit the number of protrusions 112, such as... Figure 2 The diagram shows three protruding pillars 112 arranged in a triangular pattern.

[0045] Combination Figure 5 As shown, the outer edge of the emergency button 110 extends with multiple bent spring segments, which can lock with the inner wall of the first shell 11 to improve the stability of the emergency button 110 and reduce the obstruction to the patient pressing the emergency button 110.

[0046] See Figure 7 As shown, Figure 7 This application provides a three-dimensional structural schematic diagram of an embodiment of a portable medical electrocardiogram monitor. Figure 3 .

[0047] In some implementations, the chamber 14 is also provided with a SIM card slot 140 connected to the circuit board 20, wherein the circuit board 20 also includes a 4G communication module 23.

[0048] In this embodiment, the SIM card slot 140, with its mobile phone-like design, enables remote data transmission and real-time monitoring. Specifically, compared to current ECG monitors that require a mobile phone to transmit data to a remote server, the above-mentioned device can achieve mobile network access by inserting a SIM card, allowing data to be directly transmitted to a remote server.

[0049] In some application scenarios, the above structure can be combined with conventional data transmission technology. When a patient's electrocardiogram is abnormal, the patient's GPS location is obtained and remotely transmitted to family members or medical staff. When a user presses the emergency button, the patient's GPS location is obtained and remotely transmitted to family members or medical staff.

[0050] In some implementations, chamber 14 is also equipped with an SD card slot 141 connected to circuit board 20, allowing an SD card to be inserted for storing local data. The SD card can store the patient's electrocardiogram (ECG) signals in a timely manner. For example, when a user falls or presses the emergency button, ECG signal acquisition can be triggered and stored on the SD card, enabling medical personnel to promptly diagnose the user's condition at that moment. It is worth noting that the aforementioned remote server can be a cloud server, allowing multiple monitoring terminals to acquire real-time uploaded data for monitoring the patient's condition.

[0051] Furthermore, combined Figure 8As shown, Figure 8 This application provides a three-dimensional structural schematic diagram of an embodiment of a portable medical electrocardiogram monitor. Figure 4 The cavity 14 formed by the connection of the second shell 12 and the third shell 13 can accommodate the lithium-ion battery 40. When the data interface 30 is connected to an external power source, it can provide power to the lithium-ion battery 40 to improve the device's battery life.

[0052] Furthermore, combined Figure 9 As shown, Figure 9 This application provides a three-dimensional structural schematic diagram of an embodiment of a portable medical electrocardiogram monitor. Figure 5 The second shell layer 12 is provided with a rubber sleeve 120, which is snapped into the second shell layer 12 and can cover the opening of the SD card slot 141. In this embodiment, the rubber sleeve 120 is used to reduce the intrusion of dust, moisture, etc. into the SD card slot 141.

[0053] Furthermore, a power display push block 15 is slidably provided between the first shell layer 11 and the second shell layer 12, and the power display push block 15 is electrically connected to multiple LED lights 111. Through the combination of LED lights 111 and a light-transmitting film, the device status is visualized, such as pushing the power display push block 15 to display the current remaining power, so that users can understand the remaining power status in a timely manner.

[0054] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, should be included within the protection scope of this utility model.
