Description

Technical Field

[0001] The invention relates to the field of biomedical electrodes, and in particular to a rotary connection type wire connector. Background Art

[0002] Remote electrocardiogram monitors have acquired electrical activity signals related to the cardiopulmonary system and are an important means of real-time monitoring of patients at home. Most of the usage methods are to adhere a single electrode to human skin, and then use a wire connector to connect to the wire. The other end of the wire is connected to the EDG monitor. Existing wire connectors are generally connected to the electrode by snaps. This method has great defects when used. When connecting the wire connector to the electrode, the doctor needs to press down hard to connect the two. This downward force will cause additional discomfort and pain to the patient. When the doctor needs to separate the wire connector from the electrode, a considerable upward force is also required. This force will cause the electrode to be suddenly torn off the patient's skin, causing pain to the patient again. Summary of the invention

[0003] Therefore, the present invention is made in view of the above problems, and the purpose of the present invention is to provide a rotatable wire connector, which can connect the wire connector to the electrode sheet by horizontally rotating the wire connector to avoid the discomfort caused by the original downward or upward force.

[0026] The present invention is further described below in conjunction with specific embodiments and drawings. More details are elaborated in the following description to facilitate a full understanding of the present invention. However, the present invention can obviously be implemented in a variety of other ways different from the description. Those skilled in the art can make similar generalizations and deductions based on actual application situations without violating the connotation of the present invention. Therefore, the scope of protection of the present invention should not be limited by the content of this specific embodiment.

[0027] like Figure 2-3 As shown, a rotary connection type wire connector includes: a housing 11, a conductive metal block 12, a wire 13, a spring 14, and an opening component 15;

[0028] The bottom surface of the housing 11 is provided with a circular through-hole, which is connected to the electrode sheet 2;

[0029] The conductive metal block 12 is "C-shaped" and fixed on the inner bottom surface of the housing 11, wherein the "C-shaped opening" of the conductive metal block 12 is aligned with the edge of the circular through-opening of the housing 11 in the vertical direction;

[0030] One end of the wire 13 is connected to the conductive metal block 12;

[0031] The spring piece 14 is composed of two parts, a curved part and a horizontal part. One end of the curved part of the spring piece 14 is fixed to the bottom surface of the shell 11, and the other end is connected to the horizontal part. The horizontal part of the spring piece 14 is located above the circular through-hole of the shell 11, and a stopper 141 is provided at the opposite end of the curved part of the spring piece 14 to the horizontal part.

[0032] The opening component 15 is cylindrical, and the upper end is movably connected to the top surface of the shell 11. The opening component 15 can rotate inside the shell 11, wherein the top surface of the opening component 15 is an arc surface, the purpose of which is to reduce the friction between the top surface of the opening component 15 and the top surface of the shell 11;

[0033] like Figure 4-5 As shown, the opening assembly 15 is provided with a rod 151 and a rubber 152;

[0034] One end of the rod 151 is fixed to the middle of the opening assembly 15, and the other end is embedded in the horizontal portion of the spring sheet 14. The rod 151 props up the horizontal portion of the spring sheet 14 so that the horizontal portion of the spring sheet 14 is located on one side of the circular through-hole of the housing 11.

[0035] The rubber 152 is cylindrical and fixed to the bottom surface of the opening component 15;

[0036] The electrode sheet 2 includes a conductive metal head 21 and an electrode 22 .

[0037] Preferably, as an implementable embodiment, a plurality of grooves are provided on the bottom surface of the rubber 152 , which can further increase the friction between the rubber 152 and the conductive metal head 21 when the shell 11 is rotated by pressing downward against the conductive metal head 21 .

[0038] Preferably, as an implementable embodiment, the bottom surface of the rubber 152 is provided with an arc-shaped groove. After the conductive metal head 21 is inserted into the shell 11, the bottom surface of the rubber 152 can wrap the upper end of the conductive metal head 21, further increasing the friction between the rubber 152 and the conductive metal head 21.

[0039] Preferably, as an implementable embodiment, the joint between the horizontal portion of the spring sheet 14 and the rod 151 is arc-shaped, and the arc-shaped opening faces the rod 151, the purpose of which is to prevent the rod 151 from being affected by the elastic force of the spring sheet 14 when it is reset, and to allow the rod 151 to rotate to the bent portion of the spring sheet 14.

[0040] Preferably, as an implementable embodiment, the nesting surface between the rod 151 and the spring sheet 14 is rounded, and the rounded nesting surface can reduce friction when the spring sheet 14 moves, thereby being able to better move the spring sheet 14.

[0041] Working principle of the present invention:

[0042] First, put the electrode 22 in contact with the skin, move the housing 11 downward, and the conductive metal head 21 enters the housing 11 along the circular through-hole of the housing 11 and contacts the bottom surface of the rubber 152. Figure 6 As shown, a very small downward force is used to rotate the housing 11. Due to the abutment between the rubber 152 and the conductive metal head 21, the friction between the rubber 152 and the conductive metal head 21 is increased through the rubber 152, so that the opening component 15 is positioned. During the rotation of the housing 11, the connection between the spring 14 and the rod 151 is moved from the original horizontal part of the spring 14 to the curved part of the spring 14, and the rod 151 no longer stretches the horizontal part of the spring 14. The horizontal part of the spring 14 is reset and clamps the conductive metal head 21 together with the conductive metal block 12. If the doctor needs to separate the wire connector 1 from the electrode sheet 2, a very small downward force is used to rotate the housing 11 in the opposite direction, and the rod 151 moves back to the horizontal part of the spring 14, stretches the horizontal part of the spring 14 again, and then the wire connector 1 can be removed upward.
