Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical device technology, specifically relating to a multi-lead signal adapter. Background Technology
[0002] A multi-lead electrocardiogram (ECG) is a diagnostic tool used to assess heart function and disease. It's a non-invasive test that records changes in the heart's electrical activity by placing electrodes on the chest and limbs, providing more comprehensive and detailed ECG information. Compared to a traditional ECG that only records one direction of the heart's electrical activity, a multi-lead ECG records multiple directions, providing more accurate and detailed information that helps doctors better diagnose and treat heart conditions. Typically, a multi-lead ECG records 12 directions of the heart's electrical activity, known as a 12-lead ECG, which includes six chest leads and six limb leads.

Figure 2 This is a perspective view of the overall structure of the multi-lead signal adapter provided in this embodiment of the utility model. Figure 3 This is an exploded view of the adapter housing provided in this embodiment of the utility model.
[0031] like Figures 1-3 As shown, the signal adapter includes: a detachably connected adapter housing 1 and a fixing part 2; the adapter housing 1 includes a threaded upper housing 11 and a lower housing 12; the outer side of the lower housing 12 is provided with a plurality of grooves, which are used to engage with a plurality of protrusions on the fixing part 2; and the inner side of the lower housing 12 is provided with a plurality of first adsorption members 121 at intervals, which are used to engage with a plurality of second adsorption members 211 provided inside the fixing part 2; a plurality of through holes are uniformly opened on the same side of the upper housing 11 and the lower housing 12, and a slot is opened at the joint of the upper housing 11 and the lower housing 12, the slot being located on the side of the upper housing 11 parallel to the plurality of through holes, and the slot being used to place the protruding structure 31 of the coil guard 3.
[0032] Here, we will first describe in detail the various structures within the adapter housing 1. For example... Figure 3 As shown, a plurality of first positioning blocks 122 and a plurality of second positioning blocks 123 are integrally formed around the inner wall of the lower housing 12. The plurality of first positioning blocks 122 and the plurality of second positioning blocks 123 are used to be engaged with the inner wall of the upper housing 11 to position the installation position of the upper housing 11 and the lower housing 12. Furthermore, at least one threaded through hole 1220 is provided in the plurality of first positioning blocks 122 and the plurality of second positioning blocks 123.
[0033] In one possible implementation, the first positioning block 122 is a combination of a quarter-cylinder and a rounded rectangular block, and the second positioning block 123 is a hexagonal prism. Exemplarily, there are two of each of the first and second positioning blocks 122, with the four positioning blocks distributed at the four corners inside the lower housing 12. The two first positioning blocks 122 are arranged parallel to each other on the side of the lower housing 12 closest to where the protective coil 3 is placed, and the two second positioning blocks 123 are arranged parallel to each other on the side of the lower housing 12 closest to the multiple through holes. The first positioning block 122 has two threaded holes, and the second positioning block 123 has one threaded hole.
[0034] Here, both the first adsorption element 121 and the second adsorption element 211 are rectangular magnetic pieces, and the number of rectangular magnetic pieces is at least two. For example, as shown... Figure 3 As shown, two first adsorption components 121 are laid on the inner bottom of the lower housing 12. At least one circuit board 4 is disposed inside the lower housing 12, spaced apart from the multiple first adsorption components 121. The circuit board 4 is used to transfer multi-lead signals acquired by an external signal acquisition device. Furthermore, multiple female connectors 41 are fixedly installed inside the adapter housing 1, and these female connectors 41 are fixedly connected to at least one circuit board 4, with each female connector 41 corresponding to a through hole. It should be noted that the circuit board 4 can be installed according to actual needs, and the number of female connectors 41 can be adjusted according to actual conditions; neither is a necessary component of the adapter housing 1.
[0035] To clearly illustrate the positional relationship of circuit board 4, Figure 4 This is a top view of the adapter housing provided in an embodiment of this utility model. (See attached image.) Figure 4 As shown, a circuit board 4 is fixedly mounted on the first adsorption member 121. A circuit element 42 is provided on the circuit board. At the same time, multiple female connectors 41 are provided on the circuit board 4, corresponding one-to-one with the through holes.

In one possible implementation, the number of rows of through holes on the upper housing 11 is at least two, and the number of rows of through holes on the lower housing 12 is at least one. In this case, the through holes in the first row and the through holes in the second row on the upper housing 11 are staggered, or, no through holes are provided on the upper housing 11 or the lower housing 12, or, the diameter of the through holes on the upper housing 11 is different from the diameter of the through holes on the lower housing 12.
[0037] here, Figure 5 This is a side view of the adapter housing provided in an embodiment of this utility model. Figure 5 As shown, for clarity, only the slot on the lower housing 12 is shown here. It should be understood that the slot structure on the lower housing 12 is exactly the same as the slot structure on the upper housing 11. Specifically, the slot is located at the center of one side of the upper housing 11, and the slot is composed of a circular through hole and a rectangular groove, with the centers of the circular through hole and the rectangular groove coinciding.
