Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electrocardiograms, in particular to an electrode clip for electrocardiograms. Background Art
[0002] An electrocardiograph is an instrument used to record physiological electrical signals generated by cardiac activity. Due to the advantages of mature, reliable, easy-to-use, moderately priced, and harmless to patients, the myocardial cell membrane is a semipermeable membrane. In the resting state, a certain number of positively charged cations are arranged outside the membrane, and the same number of negatively charged anions are arranged inside the membrane. The potential outside the membrane is higher than that inside the membrane, which is called the polarization state. In the resting state, since myocardial cells in various parts of the heart are in a polarized state and there is no potential difference, the potential curve recorded by the current recorder is straight, which is the isoelectric line of the surface electrocardiogram.
[0003] When using the current electrocardiograph, the electrode clamp needs to be fixed on the human limbs. Since the structure of the ordinary electrode clamp is similar to that controlled by a spring, the spring will be deformed when used for too long, thus affecting the stability of the clamping. At the same time, the spring's own resilience will make it impossible to control the clamping force. When the patient is clamped for a long time, it will make the patient feel uncomfortable and even cause skin damage. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] Embodiment 1:
[0020] Please refer to Figure 1-4 , an electrode clamp for electrocardiogram, comprising an electrode clamp body 1, a rotating shaft 2 is movably installed on the adjacent inner wall of the electrode clamp body 1, two movable plates 3 are movably installed on the outer surface of the rotating shaft 2, the front surfaces of the two movable plates 3 are each provided with a groove 4, and a screw rod 5 is movably installed on the inner wall of the groove 4 of the front movable plate 3, a sliding column 13 is fixedly installed on the inner wall of the groove 4 of the rear movable plate 3, and movable blocks 6 are movably installed on the outer surfaces of the screw rod 5 and the sliding column 13, and sliding grooves 7 are provided on the upper and lower inner walls of the groove 4, a connecting rod 8 is fixedly installed on the adjacent surface of the movable block 6, and an upper support rod 9 and a lower support rod 10 are movably installed on the outer surface of the connecting rod 8, a first rotating structure 11 is provided on the upper inner wall of the electrode clamp body 1, a second rotating structure 12 is provided on the lower inner wall of the electrode clamp body 1, and a handle 14 is movably installed on the right surface of the front movable plate 3.
[0021] Specifically: During the use of the utility model, when it is necessary to examine the patient, the medical staff takes out the electrode clamp and manually rotates the handle 14 clockwise. The handle 14 rotates clockwise to drive the screw rod 5 to rotate clockwise. The screw rod 5 rotates clockwise to drive the movable block 6 to move to the left. When the movable block 6 moves to the left, the upper support rod 9 and the lower support rod 10 are driven to move to the left. At this time, the upper support rod 9 pushes the electrode clamp body 1 to move upward through the first rotating structure 11, and the lower support rod 10 moves upward through the second rotating structure 12 pushes the bottom of the electrode clamp body 1 downward to open the electrode clamp body 1 until the patient's finger can be put down. At this time, the electrode clamp is put on the patient's finger. The medical staff can control the opening and closing of the electrode clamp at any time according to the clamping condition of the electrode clamp body 1 and the comfort level of the patient. After the clamping is completed, the sensing area 18 cooperates with the electrocardiograph to detect the patient's electrocardiogram. The result of the examination is displayed on the electrocardiograph. When it needs to be removed, the handle 14 is turned counterclockwise in the opposite direction of the above principle until the electrode clamp can be removed.
[0022] In this embodiment: the inner wall of the electrode clamp body 1 is provided with a sensing area 18 .
[0023] Specifically: the sensing area 18 itself is electrically connected to the electrocardiograph, and the sensing area 18 senses the patient's electrocardiogram and transmits it back to the electrocardiograph.
[0024] In this embodiment: the left end of the handle 14 is fixedly connected to the right end of the screw rod 5, the upper and lower surfaces of the movable block 6 are movably connected to the inner wall of the slide groove 7, the left end of the upper support rod 9 is movably connected to the surface of the first rotating structure 11, and the left end of the lower support rod 10 is movably connected to the surface of the second rotating structure 12.
[0025] Specifically, the handle 14 can drive the screw rod 5 to rotate, and the slide groove 7 provides a stable supporting force for the movement of the movable block 6.
[0026] Working principle: The utility model drives the screw rod 5 to rotate through the handle 14, thereby driving the movable block 6 and the upper support rod 9 and the lower support rod 10 to move, so as to control the opening and closing of the electrode clamp. When the movable block 6 moves to the left, it drives the connecting rod 8 to move to the left, thereby pushing the upper support rod 9 and the lower support rod 10 to move to the left. In the process of the upper support rod 9 and the lower support rod 10 moving to the left, the electrode clamp is pushed to open, and when it moves to the right, the electrode clamp is pushed to close. Compared with the related art, the electrode clamp for electrocardiogram provided by the utility model has the following beneficial effects: the design can avoid the deformation of the spring due to long-term use, thereby affecting the stability of the clamping, while improving the patient's use experience and the comfort of the device.

[0029] Specifically: after clamping the patient, the medical staff can wrap the patient's fingers with the cloth strip 15. During the wrapping process, the cloth strip 15 needs to fit the surface of the patient's fingers. When the wrapping is completed, the Velcro thorn surface 17 and the Velcro fleece surface 16 are fit together to complete the fixation. When the patient moves a large range, it can also be fixed directly by tying knots.
[0030] In this embodiment, the cloth strip 15 is made of a soft material.
[0031] Specifically: The softness of the cloth strip 15 improves the comfort of the patient when using it.
[0032] Working principle: The utility model uses a cloth strip 15 to fix the electrode clamp on the patient's finger. Compared with the related art, the electrocardiogram electrode clamp provided by the utility model has the following beneficial effects: the design fixes the electrode clamp by the cloth strip 15, thereby avoiding the phenomenon of the electrode clamp falling off, which affects the detection result.
