Description

Technical Field

[0001] The utility model relates to the technical field of electrocardiograms, in particular to a dynamic electrocardiogram monitoring electrode fixing device. Background Art

[0002] An electrocardiogram is a method of recording the electrical activity of the heart. By placing conductive electrodes at specific locations on the patient's body, the electrical signals generated by the heart are measured and recorded. An electrocardiogram is a medical device that helps doctors diagnose and is now widely used in medicine.

[0003] In the prior art, a Chinese patent with the authorization announcement number CN116491949A discloses a dynamic electrocardiogram monitoring electrode fixing device, which belongs to the field of electrocardiogram. Its technical points include an electrode head and a protective shell wrapped around the outside of the electrode head, an air inlet groove is provided in the middle of the upper end of the protective shell, and three ventilation grooves 1 are evenly provided on the outer side of the lower end of the protective shell. The upper part of the inner surface of the three ventilation grooves 1 is provided with ventilation grooves 2 connected to the air inlet groove. The outer side of the lower end of the protective shell is evenly provided with three suction cups for tightening the skin, and the upper parts of the three suction cups extend to the inside of the three ventilation grooves 1 on the same side. The dynamic electrocardiogram monitoring electrode fixing device described in the present invention can increase the skin temperature at the alcohol application site by heating the suction cup and massage ball so that when it is attached to the skin, it can relieve the tension of the monitored person, thereby accelerating the disappearance of goose bumps, making it easier for the suction cup to be adsorbed on the skin, and then facilitating the fixing of the electrode head on the skin.

[0004] At present, the electrode fixing device driven by the market still has certain shortcomings when in use. As shown in the above-mentioned documents, heating is used to reduce the discomfort caused by the instantaneous contact between the device and the human body. However, the suction cup used in the device will wear out over a long period of time and cannot be used for adsorption. Since the suction cup is small and there are many of them, it is troublesome to replace it. At the same time, the connecting wire of the device is easily separated from the electrode head after being pulled, and the tensile strength is low, which makes it inconvenient to use. Utility Model Content

[0005] The utility model aims to provide a dynamic electrocardiogram monitoring electrode fixing device to solve the problems of low tensile strength of the electrode fixing device and inconvenience in replacing the suction cup in the above-mentioned background technology.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a dynamic electrocardiogram monitoring electrode fixing device, including an electrode head, a connecting wire is connected to the right end of the electrode head, and three groups of suction cups are installed at the bottom of the electrode head:

[0007] A fixing rod is fixed to the right end of the electrode head, and a bending mechanism is provided at the right end of the fixing rod, through which the tensile strength of the fixing device can be increased to prevent the connection line from separating from the electrode head and falling off;

[0008] A fixing ring is fixed on the top of the suction cup, and a disassembly and assembly mechanism is arranged inside the fixing ring. The suction cup can be replaced through the disassembly and assembly mechanism, thereby improving replacement efficiency.

[0009] Furthermore, the bending mechanism includes a rotating block, and the rotating block rotates on the side of the fixed rod, a fixed plate is fixed on the right side of the rotating block, and a through hole is opened through the side of the fixed plate, and an extrusion mechanism is arranged on the top of the fixed plate.

[0014] Furthermore, the push rod penetrates and slides inside the slide groove, a clamping groove is provided at the bottom of the electrode head, and three groups of the clamping groove and the fixing ring are provided.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The dynamic electrocardiogram monitoring electrode fixing device can squeeze and bend the connecting wire by rotating the fixing plate. After the connecting wire is bent into a V shape, it will not directly act on the electrode head when subjected to tension, and the force direction will be changed, thereby increasing the tensile strength of the connecting wire. Then the extrusion block is rotated to the upper surface of the connecting wire for extrusion, and the thread positioning is performed by the nut, which can further enhance the tensile strength of the connecting wire of the fixing device. Secondly, the suction cup will be worn out after long-term use, and it will leak and cannot be used. The suction cup can be disassembled by telescopic sliding of the slider, which is simple and quick to operate, reduces the operation process, and improves the efficiency of disassembly;

[0017] 2. A fixing plate is provided. By rotating the fixing plate and the fixing rod, the connecting wire can be bent, thereby changing the direct force direction of the connecting wire and improving the tensile strength of the connecting wire;

[0018] 3. An extrusion block is provided. The extrusion block can squeeze the connecting wire through the rotation of the threaded rod. When the connecting wire is subjected to force, the resistance between the extrusion block and the connecting wire will increase, thereby further enhancing the tensile strength and preventing the connecting wire and the electrode head from falling off;

[0019] 4. A nut is provided, and the threaded sliding between the nut and the threaded rod can drive the fixing plate and the extrusion block to be extruded and fixed, thereby preventing the fixing plate from rotating at will and affecting the use effect;

[0020] 5. A slider is provided, which can move inside the card slot through telescopic sliding, thereby driving the fixing ring and the electrode head to separate, so as to disassemble and replace the three sets of suction cups, preventing the suction cups from being worn and requiring a more complicated disassembly method, which affects normal use.

The bending mechanism can increase the tensile strength of the fixing device to prevent the connecting wire 3 from separating from the electrode head 1 and falling off. A fixing ring 201 is fixed to the top of the suction cup 2, and a disassembly and assembly mechanism is arranged inside the fixing ring 201.

Before the fixing device is used, the connecting line 3 is passed through the through hole 104 and then the fixing plate 103 is pushed. When the fixing plate 103 is pushed, the rotating block 102 can be driven to move. When the rotating block 102 moves, it can be rotated by the fixed rod 101. When the fixed plate 103 rotates, the through hole 104 can be driven to rotate. When the through hole 104 rotates, the inner wall can extrude and bend the connecting line 3. After being extruded, the connecting line 3 can be V-shaped, thereby changing the direct force direction of the connecting line 3 and improving the tensile resistance of the connecting line 3 of the fixing device.

A rotating groove 109 is opened on the top of the fixed plate 103, and the threaded rod 106 of the fixing device can be rotated by the rotating shaft 105. When the threaded rod 106 rotates, the extrusion block 107 can be driven to rotate.

After the slider 203 slides to the specified position, the fixing ring 201 is pulled. When the fixing ring 201 is pulled, the slider 203 can be driven to slide out of the slot 206. At this time, the fixing ring 201 can be separated from the electrode head 1, so that the suction cup 2 can be disassembled, which is convenient for the quick replacement of the suction cup 2 after it is worn.
