Description

Technical Field

[0001] The present invention relates to the field of fixing devices, and particularly to a non-invasive electrocardiogram chest lead electrode fixing device for newborns. Background Art

[0002] The non-invasive electrocardiogram chest lead electrodes for newborns refer to the electrodes placed at specific positions on the chest during non-invasive electrocardiogram examinations of newborns. These electrodes can record and reflect the electrical activities of the heart and form an electrocardiogram. Specifically, the chest lead electrodes include six points, namely V1, V2, V3, V4, V5, and V6, which are located at the fourth intercostal space on the right margin of the sternum (V1), the fourth intercostal space on the left margin of the sternum (V2), the midpoint of the connection line between V2 and V4 leads (V3), the fifth intercostal space at the midclavicular line on the left (V4), the same level as V4 lead at the left anterior axillary line (V5), and the same level as V4 lead at the left midaxillary line (V6). After these electrodes are connected to an electrocardiograph, a current loop can be formed, thereby depicting the waveform of the electrical activities of the heart and helping doctors evaluate the heart health status of newborns.

[0003] In the prior art, a Chinese utility model patent with the publication number "CN209932731U" and the patent name "A fixing device for electrocardiogram chest lead electrodes" records the following technical solutions: "The integrated design of the chest lead electrodes is achieved through six positioning parts and color markings on the fixing base, assisting medical staff to quickly place the chest lead electrodes and connect the lead wires of the electrocardiograph, shortening the detection time, improving the detection efficiency, and preventing the chest lead electrodes from falling off. The body type and skin condition of the subject will not affect the present invention, and it has a wide range of applicable populations; each positioning part is provided with a number of positioning holes, and the position of the chest lead electrodes can be specifically adjusted according to different individuals, which is flexible to use and beneficial to improving the accuracy of the electrocardiogram; the fixing base is also provided with two notches corresponding to the breasts, so that the present invention will not cause compression on the breasts, which is beneficial to improving the comfort of the subject, especially female subjects and obese male subjects, and can make the placement of the chest lead electrodes more conformable, improving the accuracy of the detection; the present invention is a one-time investment, reusable, easy to disinfect, the templates can be rotated for use, and the sterilization is thorough, avoiding cross-infection, and the production cost is not high." However, in the actual use of this technical solution, after the fixed column deforms the positioning hole by squeezing it, the fixed column is inserted and fixed in the positioning hole to fix the flat electrode. However, after repeatedly inserting the fixed column into the positioning hole, the positioning hole will deform and expand and cannot be restored. As a result, after long-term use, the fixed column cannot be fixed in the positioning hole again, which will cause the flat electrode to become loose or fall off, and will affect the examination effect of newborns. At the same time, because the lead wire is inserted into the jack on the fixed column and there is a lack of fixing measures for the lead wire, when the flat electrode is in use, after the lead wire is subjected to an external pulling force, the lead wire will become loose or fall off from the fixed column, causing the connection between the electrocardiograph and the flat electrode to be disconnected, and thus unable to effectively examine newborns; Therefore, to solve the above technical problems, the present invention proposes a fixed device for non-invasive electrocardiogram chest leads for newborns.

And with the elastic binding force of the elastic binding band 10, the flat electrodes can be closely fixed on the person to be tested; As Figure 5 and Figure 6 shown in the figure, insertion holes 19 are provided on the top surfaces of the limit sockets 17, and the lead wires 7 are inserted and installed in the insertion holes 19. By inserting the lead wires 7 into the insertion holes 19, the flat electrodes can be connected to the electrocardiograph to obtain a new electrocardiogram; As Figure 6 shown in the figure, a pair of symmetric L-shaped side plates 20 are fixedly installed on the outer walls of the tops of the limit sockets 17.

[0019] The specific working principles of the first fixing mechanism 8 and the second fixing mechanism 9 are as follows: First, according to the body size of the newborn, pass the connecting plug rods 15 installed on the top surfaces of the first flat electrode 1, the second flat electrode 2, the third flat electrode 3, the fourth flat electrode 4, the fifth flat electrode 5, and the sixth flat electrode 6 through the adjustment jacks 14 opened at the corresponding connecting parts 13 in sequence from the bottom surface of the elastic restraint belt 10, and screw the limit socket 17 onto the connecting plug rod 15 protruding from the adjustment jack 14, so that the connecting plug rod 15 is threadedly connected to the thread groove 18 opened at the bottom end of the limit socket 17 through the external thread 16 opened on the outer wall. In this way, the first flat electrode 1, the second flat electrode 2, the third flat electrode 3, the fourth flat electrode 4, the fifth flat electrode 5, and the sixth flat electrode 6 can be fixedly connected to the elastic restraint belt 10. Subsequently, place the elastic restraint belt 10 on the front and back of the newborn's chest, and let the hook surface 11 and the loop surface 12 of the magic tape be adhered to each other to complete the wearing operation of the elastic restraint belt 10, so that the first flat electrode 1, the second flat electrode 2, the third flat electrode 3, the fourth flat electrode 4, the fifth flat electrode 5, and the sixth flat electrode 6 are closely attached to the corresponding fourth intercostal space on the right margin of the sternum and the fourth intercostal space on the left margin of the sternum of the newborn under the elastic restraint force of the elastic restraint belt 10. Moreover, the third flat electrode 3 is closely located between the midpoints of the connections of the first flat electrode 1 and the fourth flat electrode 4, at the intersection of the midclavicular line and the fifth rib, the fifth flat electrode 5 is at the horizontal position of the left anterior axillary line and the fourth flat electrode 4, and the sixth flat electrode 6 is at the horizontal position of the left midaxillary line and the fourth flat electrode 4, thereby being able to avoid the problems of loosening or falling off of the flat electrodes during use. At the same time, if the positions of the flat electrodes do not correspond, the positions of the flat electrodes can be readjusted through the several adjustment jacks 14 opened at the corresponding connecting parts 13; With the use of the second fixing mechanism 9, after the corresponding lead wires 7 are sequentially inserted into the insertion holes 19 opened on the top surface of the limit sockets 17 corresponding to the first flat electrode 1, the second flat electrode 2, the third flat electrode 3, the fourth flat electrode 4, the fifth flat electrode 5 and the sixth flat electrode 6, they can be connected to the electrocardiograph. Before the detection, rotate the knob 24 on the vertical outer wall of the L-shaped side plate 20 installed on both sides of the top end of the limit socket 17. The knob 24 will drive the threaded rod 23 to perform a threaded rotation operation in the threaded hole 22 opened on the vertical side wall of the L-shaped side plate 20 and move inward. Moreover, the rotating block 25 installed at the inner end of the threaded rod 23 will rotate in the convex groove 29 opened on the outer wall of the outer side plate 27 and push the outer side plate 27, so that the sliding block 28 installed on the bottom surface of the outer side plate 27 slides in the sliding opening 21 opened on the top surface of the transverse part of the L-shaped side plate 20. The outer side plate 27 will push the arc-shaped clamping plate 26 on the inner wall to move in the opposite direction until the symmetrical arc-shaped clamping plates 26 move in the opposite direction and clamp the inserted rear head position of the lead wire 7 in the arc-shaped clamping plate 26 so that the knob 24 can no longer be rotated, then the lead wire 7 can be clamped and fixed. When performing non-invasive electrocardiogram detection on a neonate, it can avoid the problem that the lead wire 7 becomes loose or falls off due to the influence of external pulling force, ensure an effective non-invasive electrocardiogram examination of the neonate, and improve the detection efficiency and detection accuracy.
