Description

Technical Field

[0001] The utility model relates to the technical field of electrocardiogram equipment, and particularly relates to a lead electrode connection structure for preventing detachment. Background Art

[0002] An electrocardiogram refers to a graph of various forms of potential changes led out from the body surface by an electrocardiograph along with the changes of bioelectricity of the heart during each cardiac cycle, in which the heart is successively excited by the pacemaker, atrium and ventricle. An electrocardiogram is an objective index for the occurrence, propagation and recovery processes of cardiac excitation, and is usually used for the examination of diseases such as arrhythmia, myocardial infarction, myocardial ischemia, ventricular and atrial hypertrophy, etc. An electrocardiograph is a common medical device used to detect and record electrical signals to obtain an electrocardiogram pattern; when in use, electrodes are placed on the limbs and chest of the human body to record and reflect the electrical signals of the heart, and then represented by curves to form an electrocardiogram.

[0003] When recording and reflecting the electrical signals of the heart through electrodes, the electrodes do not discharge electricity to the heart, but record the electrical signals of the heart and will not cause harm to the heart; if there is a problem with the heart, the electrical signals of the heart will be abnormal, and the curve of the electrocardiogram will also change. Doctors can judge whether there is a problem with the patient's heart through the curve changes of the electrocardiogram. Existing limb lead electrodes include lead electrodes and fixing clips; when in use, the lead electrodes are connected to the fixing clips, and then the fixing clips are tightly clamped on the limbs of the human body. The fixing clips transmit the sensed signals to the electrocardiograph through the lead electrodes; the connection method between the lead electrodes and the fixing clips is that a metal sheet is arranged on the inner side surface of the fixing clip to sense signals, and a part of the metal sheet extends out of the fixing clip and is rolled into a connection cylinder suitable for inserting the end of the lead electrode; when in use, the end of the lead electrode is inserted into the interior of the connection cylinder, and the signals sensed by the metal sheet can be transmitted to the electrocardiograph; the current problem is that after a period of use, when the lead electrodes are frequently inserted and pulled out of the connection cylinder, the connection will become loose, which not only affects the stable transmission of signals, but also may cause the lead electrodes to fall off, bringing inconvenience to the electrocardiogram examination work.

[0004] Therefore, how to improve the existing lead electrode connection structure so that it can be firmly connected, the signal transmission is stable and it is not easy to fall off, thereby improving the work efficiency of electrocardiogram examination, is a technical problem that has not been solved in the prior art.

[0045] When using the anti - detachment lead electrode connection structure of this embodiment, the insertion end of the electrocardiogram lead electrode 4 is inserted into the middle through - hole 21 of the cylindrical connecting portion 2, and then the limiting and fixing member 7 is clamped at the arc - shaped through - hole 22 and the long strip opening 31 to limit and fix the electrocardiogram lead electrode 4. After fixation, the fixing clip is clipped onto the limbs of the patient to perform an electrocardiogram test on the patient.

[0046] That is to say, the anti - detachment lead electrode connection structure of this embodiment can limit and fix the electrocardiogram lead electrode 4 in the middle through - hole 21 by the limit fixing member 7, which can avoid the problem of loose connection caused by frequent plugging and unplugging.

[0047] As Figure 4 shown, the electrocardiogram lead electrode 4 includes: an insertion part 5 and a main body part 6; a spherical part 52 is provided in the middle of the insertion part 5, the outer diameter of the spherical part 52 is larger than the outer diameters of the two end parts of the insertion part 5 located at both ends of the spherical part 52, and is less than or equal to the inner diameter of the middle through - hole 21; after the insertion part 5 is inserted into the middle through - hole 21, the limit fixing member 7 is clamped and fixed at the bottom of the spherical part 52 through the arc - shaped through - hole 22 and the long strip opening 31; the top of the main body part 6 is fixedly connected to the bottom of the insertion part 5, and the bottom is adapted to be connected to the lead wire. When the insertion part 5 is inserted into the middle through - hole 21, the spherical part 52 abuts against the inner wall of the middle through - hole 21, and then the limit fixing member 7 is clamped at the bottom of the spherical part 52 to limit and fix the insertion part 5.

[0048] The insertion part 5 includes: a top end part 51, a spherical part 52 and a bottom end part 53; the top end part 51 is cylindrical, the top is hemispherical, and the bottom is fixedly connected to the top of the spherical part 52; the spherical part 52; the bottom end part 53 is cylindrical, the top is fixedly connected to the bottom of the spherical part 52, and the bottom is fixedly connected to the top of the main body part 6.

[0049] A plurality of long strip through - holes 61 communicating with the top end part 51, the spherical part 52 and the bottom end part 53 are uniformly arranged on the insertion part 5, and the length of the long strip through - hole 61 is less than the length of the insertion part 5. This design makes the insertion part 5 plastic and can be conveniently inserted into the middle through - hole 21.

[0050] The spherical part 52 is formed by a plurality of arc - shaped surfaces 62 connecting the top end part 51 and the bottom end part 53, which are arranged between two adjacent long strip through - holes 61. The design of the spherical part 52 enables the insertion part 5 to be limited and fixed in the middle through - hole 21.

[0051] The insertion part 5 is made of an elastic and deformable material, and the outer diameter of the spherical part 52 is greater than or equal to the inner diameter of the middle through - hole 21. When the outer diameter of the spherical part 52 is greater than the inner diameter of the middle through - hole 21, the insertion part 5 can be inserted into the middle through - hole 21 by extrusion, so that the insertion part 5 can be fixed in the middle through - hole 21 without the limit fixing member 7 and will not slip off.

[0052] As Figure 5-6As shown, the straight connection part 3 includes a first straight plate 32 and a second straight plate 33. One end of the second straight plate 33 is fixedly connected to one end of the first straight plate 32 at a 90° angle. The cylindrical connection part 2 is integrally formed at the other end of the second straight plate 33.

[0053] As Figure 7 As shown, the limit fixing part 7 includes a U-shaped main body part 71 and operating parts 72 integrally formed at both ends of the U-shaped main body part 71. When the limit fixing part 7 is clamped at the position of the arc-shaped through hole 22, a part of the limit fixing part 7 enters the inside of the middle through hole 21. The operating part 72 can conveniently remove the limit fixing part 7 from the arc-shaped through hole 22.

[0054] The operating part 72 includes a first part 73 and a second part 74. The first part 73 and the second part 74 are arc-shaped bends, and an angle of 100° - 130° is formed between the axes.

[0055] When the limit fixing part 7 is clamped at the position of the arc-shaped through hole 22, a part of the U-shaped main body part 71 or the operating part 72 enters the inside of the middle through hole 21. Entering the inside of the middle through hole 21 and abutting against the bottom of the spherical part 52 can better limit and fix the insertion part 5.

[0056] The using method of the anti-disconnection lead electrode connection structure in this embodiment is as follows: When in use, insert the insertion part 5 of the electrocardiogram lead electrode 4 into the middle through hole 21 of the cylindrical connection part 2, and then clamp the limit fixing part 7 at the position of the arc-shaped through hole 22 and the long strip opening 31 at the bottom of the spherical part 52. The insertion part 5 is limited and fixed by the limit fixing part 7. After fixing, clamp the fixing clip on the limbs of the patient to perform an electrocardiogram test on the patient.

[0057] Obviously, the above embodiments are only examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of this innovative technical solution.
