Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a magnetic electrocardiogram electrode. Background Art

[0002] ECG electrodes are medical devices used in hospitals specifically for electrocardiogram (ECG) monitoring and are widely used clinically. Currently, most electrodes in these electrodes are snap-on electrodes. When using an ECG monitor, the ECG lead wires must be connected to the ECG electrodes and then adhered to specific areas of the patient's body. Current ECG electrodes have adhesive and graphite electrodes on the back, and metal buttons on the front that connect to the graphite electrodes. The corresponding ECG lead wire connectors have metal female buckles, and the ECG lead wires connect to the ECG electrodes via female and male buckle buttons.

[0003] In clinical practice, ECG monitors are inconvenient to move. When patients need to temporarily get up and out of bed, it is usually necessary to disconnect the patient from the ECG monitor. There are two common methods at this time. One is to directly remove the ECG electrodes from the patient and re-paste or replace the ECG electrodes after the patient returns. The other is to disconnect the ECG electrodes from the ECG lead wires. Removing the ECG electrodes from the patient and reconnecting them will cause the position of the ECG electrodes to change. Removing and pressing the ECG electrode patches will increase the patient's pain. In order to avoid changes in the ECG electrode adhesion position and reduce electrode waste, the electrodes are usually retained on the patient and the ECG lead wires are disconnected from the ECG electrodes. When reconnecting the ECG lead wires to the ECG electrodes, when removing the heart electrodes, you need to press again to remove the heart electrodes from the electrodes, which will be painful and provide a poor experience for patients. Utility Model Content

[0004] Aiming at the problem in the prior art that the process of connecting and separating an ECG lead wire and an electrode sheet easily causes discomfort to the patient, the utility model provides a magnetic ECG electrode.

[0005] The technical solutions adopted in this utility model are as follows:

[0006] A magnetic electrocardiogram electrode comprises an electrode core and an electrode patch arranged around the electrode core. A first connector is provided on one side of the electrode core, and a second connector that cooperates with the first connector is provided on the lead wire. The first connector and the second connector are detachably connected by magnetic attraction.

[0007] After adopting this technical solution, the utility model changes the original connection method of fastening the sub-button and the mother button (similar to the letter buttons on clothes), and directly connects the first connecting part and the second connecting part by magnetic attraction. The magnetic connection can avoid pressing downward during the connection process, effectively improving the comfort of the patient.

[0008] Preferably, the first connector includes a chassis connected to the electrode core, the chassis is connected to a connecting column, and the second connector includes a connecting cylinder that can accommodate the connecting column, and the connecting column and the connecting cylinder are connected by magnetic force.

[0009] After adopting this technical solution, the lead wire and the electrode sheet are connected by sleeve-mounting the connecting tube on the connecting column, which can increase the contact area between the lead wire and the electrode sheet, withstand the lateral pulling force, and improve the connection stability.

[0010] Preferably, a plurality of first protrusions are provided in an annular direction around the connecting post on the chassis with the connecting post as the center, and a gap between two adjacent first protrusions forms an accommodating groove. The connecting tube is provided with an annular disk, and a second protrusion that can be placed in the accommodating groove is provided on the annular disk at a position corresponding to each accommodating groove.

[0011] A limiting block is provided on one side of the second protrusion, a limiting groove matched with the limiting block is provided on the first protrusion, and a driving mechanism for driving the second protrusion to rotate is connected between the second protrusion and the first protrusion.

[0012] After adopting this technical solution, in order to further improve the stability of the connection, the utility model also provides a locking mechanism that can block the longitudinal pulling force. When the connecting tube is sleeved on the connecting column, the second protrusion enters the accommodating groove, and the second protrusion is rotated by the driving mechanism, so that the limit block enters the limit groove to improve the longitudinal connection stability of the electrode sheet.

[0013] Preferably, the driving mechanism is a first magnet and a second magnet respectively arranged on the limiting groove and the limiting block, the first magnet and the second magnet are connected by magnetic attraction, and the magnetic attraction between the first magnet and the second magnet is greater than the friction force between the second protrusion and the limiting groove.

[0014] After adopting this technical solution, when the second protrusion enters the accommodating groove, the first magnet and the second magnet are arranged relative to each other, so that the friction force of the second protrusion is overcome by the magnetic attraction force between the first magnet and the second magnet, driving the second protrusion to rotate, so that the limit block enters the limit groove, thereby improving the longitudinal connection stability of the electrode sheet.

[0015] Preferably, both the first bump and the second bump are fan-shaped structures.

[0016] Preferably, the limiting groove provided on each first protrusion is provided on a side away from the limiting groove on the adjacent first protrusion.

[0017] After adopting this technical solution, the driving mechanism between each first protrusion and the second protrusion can drive the entire second connecting member to move in the same direction, thereby avoiding mutual interference.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0019] 1. The present invention changes the original connection method of fastening a sub-button and a mother button (similar to the letter buttons on clothes), and directly connects the first connecting part and the second connecting part by magnetic attraction. The magnetic connection can avoid pressing downward during the connection process, effectively improving the comfort of the patient.

[0020] 2. In order to further improve the stability of the connection, the utility model is also provided with a locking mechanism that can block the longitudinal pulling force. When the connecting tube is sleeved on the connecting column, the second protrusion enters the accommodating groove. The second protrusion is rotated by the driving mechanism, so that the limit block enters the limit groove to improve the longitudinal connection stability of the electrode sheet.

In addition, the terms "first", "second", "third", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0027] The following combination Figure 1-Figure 2 The utility model is described in detail.

[0028] Example 1

[0029] like Figure 1-2 As shown, a magnetic ECG electrode comprises an electrode core 2 and an electrode patch 1 arranged around the electrode core 2, a first connector is provided on one side of the electrode core 2, a second connector that cooperates with the first connector is provided on the lead wire, and the first connector and the second connector are detachably connected by magnetic attraction. It should be noted that the structures not mentioned in the electrode patch are the same as those in the prior art, and the second connector that cooperates with the first connector is made of a wire material to ensure smooth connection of the current. This embodiment changes the original connection method of fastening the sub-button and the mother buckle, and directly connects the first connector and the second connector by magnetic attraction. The magnetic connection can avoid pressing down during the connection process, effectively improving the comfort of the patient.

[0030] In this embodiment, the first connector includes a chassis connected to the electrode core 2, to which a connecting post 6 is connected. The second connector includes a connecting tube 7 that accommodates the connecting post 6. The connecting post 6 and the connecting tube 7 are connected by magnetic force. It should be noted that both the connecting post 6 and the connecting tube 7 are made of metal magnets to ensure conductivity. Connecting the lead wire and the electrode sheet by fitting the connecting tube 7 over the connecting post 6 increases the contact area between the lead wire and the electrode sheet, resists lateral pulling forces, and improves the stability of the connection.

[0031] Example 2

[0032] This embodiment is substantially the same as the first embodiment, except that: a plurality of first protrusions 3 are provided in a circular pattern around the connecting post 6 on the chassis, with the connecting post 6 as the center. The gap between two adjacent first protrusions 3 forms an accommodating groove 4. An annular disk is provided on the connecting tube 7. Second protrusions 8 that can be placed in the accommodating groove 4 are provided on the annular disk at positions corresponding to the respective accommodating grooves 4.

[0033] A limit block 9 (2 mm in length) is provided on one side of the second protrusion 8. A limit slot 5 is provided on the first protrusion 3 to cooperate with the limit block 9. The second protrusion 8 is connected to a driving mechanism that drives the second protrusion 8 to rotate. In this embodiment, the driving mechanism is a first magnet and a second magnet, respectively, provided on the limit slot 5 and the limit block 9. The first magnet and the second magnet are both permanent magnets and are magnetically attracted to each other. The first magnet and the second magnet are connected by magnetic attraction, and the magnetic attraction between the first magnet and the second magnet is greater than the friction between the second protrusion 8 and the limit slot 5. The first protrusion 3 and the second protrusion 8 are both fan-shaped structures. Here, the sum of the widths of the limit block 9 and the second protrusion 8 is greater than the width of the accommodating slot 4 by approximately 1 mm, so that the second protrusion 8 and the limit block 9 can be smoothly placed into the accommodating slot 4. The limit slot 5 provided on each first protrusion 3 is provided on a side away from the limit slot 5 on the adjacent first protrusion 3.

[0034] To further improve the stability of the connection, this embodiment also provides a limiting mechanism that can resist longitudinal pulling force. When the connecting tube 7 is placed on the connecting column 6, the second protrusion 8 enters the accommodating groove 4. At this time, the first magnet and the second magnet are arranged relative to each other. The magnetic attraction between the first magnet and the second magnet causes the second protrusion 8 to rotate (the magnetic attraction overcomes the friction force to drive the second protrusion 8 to rotate), causing the limiting block 9 to enter the limiting groove 5, thereby improving the longitudinal connection stability of the electrode sheet. When the lead wire needs to be separated from the electrode sheet, it is only necessary to rotate the second connecting member in the opposite direction to overcome the magnetic attraction between the first magnet and the second magnet, thereby causing the limiting block 9 to disengage from the limiting groove 5. Then, the second connecting member can be pulled upward to separate the two.

[0035] The above-described embodiments merely represent specific implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of protection of the present application. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the technical concept of the present application, and all such variations and improvements fall within the scope of protection of the present application.
