[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1-4 , an embodiment provided by the present invention: a disposable electrocardiogram lead device, comprising a junction box 1, a first main cable 2 is connected to the left end of the junction box 1, a plug 3 is connected to the left end of the first main cable 2, a lead wire 4 is connected to the right end of the junction box 1, a tape 5 is connected to the end of the lead wire 4, twelve groups of electrode sheets 6 are arranged in the tape 5, and both the tape 5 and the electrode sheets 6 are disposable;

[0025] The device solves the problem that the repeatedly used ECG lead device is prone to cross infection in a hospital environment by using the tape 5 and the electrode sheet 6 together; and the traditional ECG lead electrodes need medical staff to fit them one by one, which has many operation steps and is time-consuming.

[0026] Furthermore, a buffer assembly 7 is provided at the right end of the plug 3. The buffer assembly 7 includes a fixed box 71, a buffer groove 72, a sliding block 73, a second main cable 74, a damper 75 and a spring 76. The right end of the plug 3 is fixedly connected to the fixed box 71. The fixed box 71 is provided with a buffer groove 72. The buffer groove 72 is movably connected to the sliding block 73. The right end of the sliding block 73 is connected to two groups of dampers 75. The outer side of the damper 75 is sleeved with a spring 76. The left side of the sliding block 73 is connected to the second main cable 74. The left end of the first main cable 2 is connected to the sliding block 73. Figure 4 As shown, the structure is used to pass through the buffer component 7. When the junction box 1 is pulled by the outside, the pulling force will act on the first main cable 2. The pulling force on the first main cable 2 will act on the sliding block 73. The force on the sliding block 73 will squeeze the damper 75 and the spring 76. The force acting on the sliding block 73 can be absorbed and buffered by the action of the spring 76 and the damper 75. During the absorption and buffering, the sliding block 73 and the first main cable 2 will have a certain displacement. When the first main cable 2 is displaced, the stability of the connection between the first main cable 2 and the plug 3 is ensured by the longer second main cable 74. The force acting between the plug 3 and the connection end is buffered and absorbed by the sliding block 73, the spring 76 and the damper 75, so that the two connections are not easy to separate under the action of external forces, and the risk of loosening and damage between the two can be greatly reduced by buffering and absorbing the force.

[0027] Furthermore, the tape 5 is made of a flexible material and has a certain curvature, and the twelve groups of electrode sheets 6 are interconnected by conductive materials. Figure 3 As shown, the structure is used to make the tape 5 of flexible material so as to adapt to the curve of the patient's skin and avoid electrode shedding or signal instability due to movement.

[0028] Furthermore, the outer surface of the tape 5 is provided with symbols, and the positions of the symbols correspond one by one to the twelve groups of electrode sheets 6. Figure 3 As shown, the structure is used to correspond one-to-one with the twelve groups of electrode sheets 6 through the symbol positions, which can fit the position of the chest curve to ensure the accurate contact between the electrode sheets 6 and the skin, so as to improve the signal conduction efficiency.

[0029] Furthermore, a patch is provided on the inner side of the tape 5, and the patch is made of a flexible material. Figure 3 As shown, this structure is used to ensure that multiple lead electrodes can be quickly pasted in place at one time on one patch, thereby reducing the number of operation steps.

[0030] Furthermore, the second main cable 74 is folded in a curved shape inside the buffer slot 72, and one side of the second main cable 74 is electrically connected to the plug 3, and the other side is electrically connected to the first main cable 2. Figure 4As shown, the structure is used to fold the second main cable 74 inside the buffer groove 72 to facilitate movement along with the sliding block 73.

[0031] Furthermore, the first main cable 2 passes through the side wall of the fixing box 71, and a sleeve 77 is fixedly installed on the outer side of the fixing box 71, and the first main cable 2 passes through the inside of the sleeve 77. Figure 4 As shown, the structure is used to prevent the first main cable 2 from being bent through the sleeve 77, thereby providing a certain degree of protection to the first main cable 2.

[0032] Working principle: When used, Figure 1 As shown, first connect the plug 3 to the connection end, and then attach the tape 5 according to the usage. Figure 3 As shown, through the patch inside the tape 5, the tape 5 can be quickly pasted in place at one time, and the symbol position corresponds to the twelve groups of electrode sheets 6 one by one, and can be extended to the back in accordance with the chest curved surface position, ensuring the accurate contact between the electrode sheet 6 and the skin to improve the signal conduction efficiency, such as Figure 4 As shown, when the junction box 1 is pulled by the outside, the pulling force will act on the first main cable 2, and the pulling force on the first main cable 2 will act on the sliding block 73. The force on the sliding block 73 will squeeze the damper 75 and the spring 76. The force acting on the sliding block 73 can be absorbed and buffered by the action of the spring 76 and the damper 75, and during the absorption and buffering, the sliding block 73 and the first main cable 2 will produce a certain displacement. When the first main cable 2 is displaced, the stability of the connection between the first main cable 2 and the plug 3 is guaranteed by the longer second main cable 74. The force acting between the plug 3 and the connection end is buffered and absorbed by the sliding block 73, the spring 76 and the damper 75, so that the two connection ends are not easily separated under the action of external forces. The above is the entire working principle of the present invention.

[0033] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
