Description

Technical Field

[0001] This utility model relates to the field of medical monitoring equipment technology, and in particular to a patch-type remote dynamic electrocardiogram recorder. Background Technology

[0002] Holter monitoring is an important tool for the clinical diagnosis of heart diseases such as arrhythmia and myocardial ischemia.

[0003] Traditional Holter monitors are bulky and have complex lead wires, which can interfere with users' daily activities when worn. Furthermore, data transmission relies on dedicated equipment, making real-time remote monitoring impossible. Existing patch-type devices are mostly single-lead fixed designs, which cannot flexibly switch lead types and lack waterproofing, thus limiting their application scenarios.

[0004] Specifically, traditional equipment and existing technologies suffer from the following core problems that limit their application effectiveness and user experience:

[0005] 1. Bulky size and complex wiring

[0006] Traditional Holter monitors require multiple leads to connect the electrode pads, which can lead to tangled cables, restricted movement, and require professional operation. While some patch-type devices simplify the lead structure, they are mostly single-lead fixed designs, which cannot meet the needs of multi-lead testing.

[0007] 2. Difficulty switching lead modes

[0008] Existing switchable lead devices rely on extended lead wires to achieve multi-contact connections, resulting in the separation of electrode pads from the main unit. Users need to manually install multiple electrode pads, which is cumbersome and prone to errors. In addition, such devices are difficult to adapt to different lead types (single / three / twelve leads) using a single main unit, leading to high costs and poor flexibility.

[0009] 3. Limitations of real-time monitoring and data transmission

[0010] Traditional devices rely on local storage and require data to be exported to dedicated equipment for analysis later, making remote real-time monitoring impossible. While some improved solutions integrate accelerometer sensors, they lack real-time data transmission capabilities, preventing doctors from dynamically tracking patients' electrocardiogram (ECG) status.

[0011] 4. Insufficient waterproofness and comfort

[0012] Existing patch-type devices mostly use non-woven fabric electrode pads and fixed encapsulation, lacking waterproof design, making it impossible for users to perform daily activities (such as showering) while wearing them. In addition, the rigid materials and separate electrode pads result in poor fit, which can easily cause skin discomfort with prolonged wear. Utility Model Content

[0013] This invention proposes a patch-type remote dynamic electrocardiogram recorder, which solves the problems of existing dynamic electrocardiogram recorders being large in size, complex in structure, and dependent on dedicated equipment for data transmission.

[0014] The technical solution of this utility model is implemented as follows:

Several spring-loaded pin holes corresponding to the spring-loaded pins are opened on the bottom shell.

[0016] Preferably, it also includes indicator bulb cotton, which is disposed between the indicator light and the indicator light hole, and the indicator bulb cotton is used for sealing and shock absorption.

[0017] Preferably, it also includes battery foam, which is fitted over the rechargeable battery and is used for shock absorption and protection.

[0018] Preferably, the battery foam is frame-shaped, which provides shock absorption and protection without affecting the heat dissipation of the rechargeable battery.

[0019] Preferably, it also includes insulating foam, which is laid between the rechargeable battery and the spring pin cable.

[0020] Preferably, the housing is an IPX7 waterproof housing.

[0021] Preferably, the device also includes a silicone patch, the upper surface of which is fixed with a retainer. The upper surface of the retainer has a slot that mates with the housing. A lower spring pin, corresponding to the spring pin, is located at the bottom of the slot. The lower spring pin is electrically connected to a lead wire connector via a lower spring pin cable. A lead wire is electrically connected to the lead wire connector.

[0022] When silicone pads are not used, disposable electrode pads can be directly connected, including single-lead electrode pads, three-lead electrode pads, or twelve-lead electrode pads. The single-lead electrode pads, three-lead electrode pads, or twelve-lead electrode pads are electrically connected to the spring pin.
