Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a carotid artery health monitoring device based on ECG. Background Technology

[0002] ECG captures the electrical signals generated by cardiac contraction through skin electrodes and converts them into waveforms, reflecting the propagation and recovery process of cardiac excitation. Traditional ECG electrode pads for monitoring the carotid artery are typically placed on the carotid artery, then secured with a strap around the neck using Velcro. However, this method has the following drawbacks in clinical use: while it secures the ECG electrode pads, only the side of the pad furthest from the skin contacts the strap, generating friction and pressure. Therefore, insufficient friction can lead to electrode displacement. To address these shortcomings, we propose an ECG-based carotid artery health monitoring device. Utility Model Content

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Please see Figure 1-7 This utility model provides a technical solution: a carotid artery health monitoring device based on ECG, comprising: a restraint structure and a carotid ECG detection structure.

[0027] The restraint structure includes a neck strap 10, mounting grooves 11 on the side of the neck strap 10, and Velcro tabs 12 and Velcro tabs 13 fixedly installed on both sides of the neck strap 10. The surface of the neck strap 10 has multiple equidistant ventilation holes 14. The upper and lower surfaces of the neck strap 10 are both provided with arc-shaped grooves 15. The neck strap 10 is made of breathable non-woven fabric. The neck strap 10 is wrapped around the patient's neck, and then the Velcro tabs 12 and Velcro tabs 13 are used to stick them together to fix the neck strap 10 to the patient's neck. The tightness of the neck strap 10 can be adjusted by adjusting the Velcro tabs 12 and Velcro tabs 13. When the neck strap 10 is fixed to the patient's neck, the ventilation holes 14 can improve the breathability of the patient's neck.

[0028] The neck ECG detection structure includes an ECG electrode 20 and an assembly assembly disposed on the right side of the ECG electrode 20 for assembly with the neck strap 10. The assembly assembly includes a threaded cylinder 30, an external thread on the outer surface of the threaded cylinder 30, an internal thread on the inner wall of the threaded cylinder 30, a locking nut 31 threaded to the outer surface of the threaded cylinder 30, and an external threaded post 32 rotatably mounted on the right side of the ECG electrode 20.

[0029] The surface of the external threaded post 32 is driven by the internal thread of the inner wall of the threaded cylinder 30. The assembly groove 11 allows the threaded cylinder 30 to pass through and move within the assembly groove 11. The external threaded post 32 is screwed into the threaded cylinder 30, and then the threaded cylinder 30 is passed through the assembly groove 11. After that, the locking nut 31 is tightened, so that the neck strap 10 can be clamped by the ECG electrode 20 and the locking nut 31. After the neck strap 10 is fixed in the patient's neck, the threaded cylinder 30 can be slid along the inner wall of the assembly groove 11, so that the ECG electrode 20 can be finely adjusted to make it accurately contact the monitored position.

[0030] The neck strap 10 is clamped by the ECG electrode plate 20 and the locking nut 31, which enhances the stability of the connection between the ECG electrode plate 20 and the neck strap 10. After the locking nut 31 is separated from the threaded cylinder 30, the ECG electrode plate 20 can be removed from the assembly groove 11, thereby separating it from the neck strap 10 and facilitating the cleaning of the neck strap 10.

[0031] The right end of the external threaded post 32 is provided with an internal hexagonal groove 40, which is compatible with an external hexagonal wrench. The middle part of the locking nut 31 is provided with a through groove for the external hexagonal wrench to pass through. When the neck strap 10 and the ECG electrode 20 are both fixed to the patient's neck, the external hexagonal wrench is inserted into the internal hexagonal groove 40. Then, rotating the external hexagonal wrench can drive the internal thread of the external threaded post 32 and the internal thread of the threaded cylinder 30 to rotate, thereby driving the ECG electrode 20 to move closer to or away from the patient's skin, and thus the tightness of the neck strap 10 can be finely adjusted.

[0032] Specifically, the working principle and operation method of this utility model are as follows:

[0033] Step 1: Wrap the neck strap 10 around the neck and secure it initially using Velcro 12 and Velcro 13;

[0034] Step 2: Screw the external threaded post 32 of the ECG electrode 20 into the threaded cylinder 30, then pass the threaded cylinder 30 through the assembly groove 11 and slide it along the assembly groove 11 to the target monitoring position.

[0035] Step 3: Tighten the locking nut 31. The locking nut 31 works in conjunction with the ECG electrode 20 to form a mechanical interlock between the ECG electrode 20 and the neck strap 10, preventing displacement of the ECG electrode 20 and the neck strap 10 due to movement.

[0036] Step 4: Insert an external hex wrench into the internal hex socket 40 and rotate it to drive the external threaded post 32 to move axially, precisely controlling the contact pressure between the ECG electrode 20 and the skin.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art based on the technical solution and concept of the present utility model should be included within the protection scope of the present utility model.
