Technical Field

[0001] This utility model relates to the field of wearable medical devices, specifically to a patch-type electrocardiogram recorder capable of collecting multiple lead patterns from the human body. Background Technology

[0002] An electrocardiogram (ECG) is a non-invasive examination method that records the electrical activity of the heart and is widely used in clinical diagnosis and monitoring. ECG recorders can accurately record human ECGs and are non-invasive and economical. Holter monitoring can record a patient's cardiac electrical activity for extended periods, helping to detect abnormalities such as occasional arrhythmias that are difficult to detect in a routine ECG. Traditional 12-lead Holter monitors are bulky and not portable, and due to the numerous ports and wires, they often introduce power line interference during signal acquisition, affecting the quality of signal acquisition. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies, this invention proposes a portable, easy-to-use, and high-quality patch-type electrocardiogram (ECG) recorder capable of acquiring multiple lead modes of the human body. It can continuously and uninterruptedly monitor and record twelve-lead ECG data of the human body over long periods of time, providing cardiologists with detailed and reliable ECG information, greatly enriching the basis for clinical diagnosis and disease assessment, and helping to improve the accuracy and efficiency of heart disease diagnosis.

Detailed Implementation

[0018] The present invention will now be further described with reference to the accompanying drawings.

[0019] Reference Figures 1-4 A patch-type electrocardiogram (ECG) recorder capable of acquiring multiple lead modes from the human body includes a patch-type ECG sensor 1 and an ECG recorder main unit 2. The ECG recorder main unit 2 and the patch-type ECG sensor 1 are connected by an internal embedded snap-fit. The ECG recorder main unit 2 is rechargeable and reusable, while the patch-type ECG sensor 1 is a disposable item that needs to be discarded after use. One side of the patch-type ECG sensor 1 is connected to the ECG recorder main unit 2, and the other side of the patch-type ECG sensor 1 contacts different parts of the human skin.

[0020] The electrocardiogram recorder host 2, such as Figure 2 As shown, the bottom of the main unit is equipped with a Type-C charging port 21 for charging the device, a probe 22 for connecting and adapting sensors with different lead modes, and a bayonet 23 for fastening the ECG recorder main unit and the sensor together. The outer ring of the probe 22 is raised, and waterproof tape can be applied at the through hole 161 of the base to better achieve the waterproof effect.

[0021] The internal structure of the ECG recorder host 2 is as follows: Figure 3 As shown, a closed chamber is formed by bonding the lower shell 24 and the upper shell 27 together. The probe 22 and the lower shell 27 are integrally injection molded to ensure waterproofing. This chamber has good water-proof and shower-proof properties. The closed chamber contains a battery 25 and a PCB circuit board 26. The lower shell 24 has slots of different shapes for fixing the PCB circuit board 26 and the battery 25.

[0022] The ECG recorder host 2 can be adapted to different sensors. Taking a 12-lead sensor as an example, the patch-type ECG sensor 1 is described.

[0023] The internal structure of the adhesive ECG sensor 1 is as follows: Figure 4As shown, the sensor includes, from the skin-contact side to the surface side, a skin-contact A-type release paper 11, a non-woven fabric single-sided adhesive 12, an A-type PU single-sided adhesive 13, a surface release paper 14, a flexible circuit 15, and a base 16.

[0024] The surface release paper 14 has surface release paper through holes 141 on its surface, and the shape of the release paper through holes 141 is consistent with the shape of the ECG recorder host 2.

[0025] The flexible circuit 15 includes a host connection point 151 and an electrode 152. The electrode 152 includes, from the skin-contact side to the surface side, a skin-contact type B release paper 17, a conductive gel 19, and a type B PU single-sided adhesive 18. The flexible circuit 15 has an insulating layer on both sides. This insulating layer can be a printed insulating ink layer, which can meet the insulation requirements between the electrode circuit and the human body.

[0026] The bottom of the base 16 has multiple parallel through holes 161, and the front and rear sides of the base 16 are respectively provided with buckles. The ECG recorder host 2 can be inserted into the base 16 from top to bottom. The probe 22 at the bottom of the ECG recorder host 2 abuts against the host connection point 151 of the flexible circuit 15 through the multiple parallel through holes 161, forming a stable electrical connection between the ECG recorder host 2 and the electrode 152. Preferably, waterproof foam is provided in the through holes 161.

[0027] The sensor base 16 and the ECG recorder host 2 are connected by built-in embedded buckles, making the structure as refined as possible, greatly reducing the overall size, and ensuring easy operation for users.

[0028] Example: A 12-lead electrocardiogram (ECG) recorder for human use includes a skin-mounted ECG sensor 1 and an ECG recorder main unit 2. The skin-mounted ECG sensor 1 includes a skin-mounted A-type release paper 11, a non-woven fabric single-sided adhesive 12, an A-type PU single-sided adhesive 13, a surface release paper 14, a flexible circuit 15, and a base 16. The flexible circuit 15 includes a main unit connection point 151 and an electrode 152. The electrode 152 includes a skin-mounted B-type release paper 17 arranged sequentially from the skin-mounted side to the surface side. The ECG recorder main unit 2 includes a Type-C charging port 21, a probe 22, a clip 23, a lower shell 24, a battery 25, a PCB circuit board 26, and an upper shell 27.

[0029] Before measurement, the ECG recorder main unit 2 needs to be fixed to the adhesive ECG sensor 1. For example... Figure 1 As shown, the ECG recorder host 2 is inserted into the base 16 from top to bottom by a snap fastener. The probes at the bottom of the ECG recorder host 2 contact the host connection point 151 of the flexible circuit 15 through multiple parallel through holes 161, forming a stable electrical connection between the measurement host 2 and the electrode 152. Next, attach the adhesive ECG sensor 1 to the subject. First, peel off the skin-adhesive side A-type release paper 11, and then smoothly attach the adhesive ECG sensor 1 to the appropriate position on the subject's chest, gently smoothing and pressing it to ensure a tight bond. After the adhesive ECG sensor 1 is firmly attached to the subject's chest, slowly peel off the surface release paper 14, then peel off the skin-adhesive side B-type release paper 17 in sequence, and attach the electrodes LA, RA, V1, RL, V2, V3, V4, V5, V6, and LL corresponding to the human body's electrode positions. The adhesive ECG sensor 1 is now attached. After completing one monitoring session, the adhesive ECG sensor 1 can be slowly peeled off the chest. Press the base 140 to pop out the ECG recorder main unit 2. The ECG recorder main unit 2 is kept for the next monitoring session, and the adhesive ECG sensor 1 is discarded. A new one will be used for the next monitoring session.
