Fig. 1 is a perspective view of an ecg signal connection box according to an embodiment of the present invention, fig. 2 is a partial perspective view of the ecg signal connection box, fig. 3 is a cross-sectional view of the ecg signal connection box, and fig. 4 is a reference view of a usage state of the ecg signal connection box.

Referring to fig. 1 and 2, the ecg signal connection box 100 includes a housing 120, a first connector 110, a chest lead connection module 130, and a limb lead connection module 140. The housing 120, for example, a six-sided housing, includes a first surface 121, a second surface 122, a third surface 123, a fourth surface 124, a fifth surface 125, and a sixth surface 126. The first surface 121 is disposed opposite to the third surface 123, the second surface 122 is disposed opposite to the fourth surface 124, and the fifth surface 125 is disposed opposite to the sixth surface 126 and connects the first surface 121, the second surface 122, the third surface 123, and the fourth surface 124.

In some embodiments, the housing 120 is a rectangular housing, and the second surface 122 is perpendicular to the first surface 121 and the third surface 123.

The first connector 110 is mounted to the first surface 121 of the housing 120, and the chest lead connection module 130 is mounted to the second surface 122 of the housing 120. In addition, the limb conduction connection module 140 is mounted on the third surface 123 of the housing 120. The second surface 122 is perpendicular to the third surface 123, and the first surface 121 is parallel to the third surface 123.

In some embodiments, the first connector 110 includes an external connector 262 for connecting the integrated electrode pads, the shaft 264 and the hub 266. Therefore, the housing 120 and the first connector 110 can rotate relatively on the first surface 121 of the housing 120 via the rotation shaft 264.

Referring to fig. 3, in some embodiments, the first connector 110 further includes a rotation angle limiter 268 disposed on the shaft 264. The inner surface of the housing 120 is provided with a first rotation angle limiting partition 310 and a second rotation angle limiting partition 320. When the first connector 110 is rotated, the rotational angle limiter 268 may contact the first rotational angle limiting spacer 310 or the second rotational angle limiting spacer 320 to limit the rotational angle of the first connector 110 and the rotational angle limiter 268 with respect to the housing 120. For example, when the rotation angle limiter 268 rotates clockwise to the first position 301 in fig. 3, the rotation angle limiter 268 contacts the first rotation angle limiting partition 310 and stops rotating. In addition, when the rotation angle limiter 268 is rotated to the second position 302 in fig. 3, the rotation angle limiter 268 contacts the second rotation angle limiting partition 320 and stops rotating. Therefore, the external connection head 262 can rotate relative to the housing 120 within the angle corresponding to the first rotation angle limiting partition 310 and the second rotation angle limiting partition 320.

In some embodiments, the rotational angle of the first connector 110 and the rotational angle limiter 268 relative to the housing 120 is about 180 degrees.

In some embodiments, the first rotation angle limiting partition 310 and the second rotation angle limiting partition 320 have an eccentric amount 303 with the center of the rotation shaft 264, for example, half the thickness of the rotation angle limiter 268, so that the first connector 110 and the rotation angle limiter 268 are accurately positioned at the predetermined position of the housing 120.

Referring to fig. 4, when the person 430 to be measured uses the electrocardiograph 410 to perform electrocardiographic measurement, as shown in the figure. Generally, the electrocardiograph 410 may be disposed on the left hand side of the person 430 to be measured, as shown in fig. 4. However, the electrocardiograph 410 is sometimes disposed on the right hand side of the person 430 to be measured due to the field or other measuring instrument.

When the electrocardiograph 410 is disposed on the right hand side of the person 430 to be measured, the conventional ecg signal connection box cannot be rotated, and the ecg cable 420 needs to be folded back to connect the electrocardiograph 410. Thus, not only the discomfort of the person 430 to be measured is caused, but also the measurement result may be affected.

By the novel ECG signal connection box 450, the direction of the chest lead connection module can be conveniently rotated from the left-hand direction facing the person 430 to be measured to the right-hand direction of the person 430 to be measured, so that the ECG data can be accurately measured no matter the ECG meter 410 is disposed on the left or right side of the person 430 to be measured.

Therefore, the measuring person only needs to rotate the ecg signal connection box 450 to a proper direction and connect the integrated electrode patches 440, so that the chest lead cable 422 and the limb lead cable 424 of the ecg cable 420 can be inserted into the corresponding connectors, respectively, and the ecg measurement can be accurately performed without affecting the person 430 to be measured. In addition, the direction of the ECG signal connection box 450 can be adjusted at any time by the measuring person according to the position of the ECG meter 410, even after the ECG cable 420 is connected, the direction of the ECG signal connection box 450 can be adjusted at any time without affecting the person 430 to be measured, so as to conveniently and accurately measure the ECG.

Referring to fig. 2, in some embodiments, the ecg signal connection box 100 further includes an insulating partition 127 and an insulating partition 128 respectively disposed on the second surface 122 and the third surface 123 of the housing 120, and the chest lead connection module 130 and the limb lead connection module 140 are disposed on inner surfaces of the insulating partition 127 and the insulating partition 128. In addition, the chest lead connection module 130 and the limb lead connection module 140 respectively include a plurality of banana sockets aligned with the corresponding openings of the insulation partition 127 and the insulation partition 128, and when the banana connectors are inserted into the corresponding banana sockets, the corresponding openings of the insulation partition 127 and the insulation partition 128 shield the metal parts of the banana connectors.

For example, the banana sockets include a first banana socket 221, a second banana socket 222, a third banana socket 223, a fourth banana socket 224, a fifth banana socket 225, a sixth banana socket 226, a seventh banana socket 231, an eighth banana socket 232, a ninth banana socket 233, and a tenth banana socket 234, which are aligned with the openings 201, 202, 203, 204, 205, 206, 211, 212, 213, and 214 respectively, and are shielded by the corresponding openings to avoid exposing the metal terminals of the banana sockets, and when the banana connectors are inserted into the corresponding banana sockets, the corresponding openings on the insulating partition 127 and the insulating partition 128 also shield the metal portions of the banana connectors to avoid exposing the metal, thereby avoiding affecting the measurement signals and effectively improving the measurement accuracy.

In some embodiments, the insulating partition 127 and the insulating partition 128 may also be integrally formed with the housing 120, without departing from the spirit and scope of the present invention.

In some embodiments, referring to fig. 7, for example, the chest lead connection module 130 and the insulating partition 127 are taken as examples, the chest lead connection module 130 is disposed on the inner surface of the insulating partition 127, and the chest lead connection module 130 includes a plurality of banana sockets aligned with the corresponding openings of the insulating partition 127.

Hereinafter, the banana connectors 710 and 720 will be described as examples. Banana connector 710 includes a metal terminal 714 and an insulating handle 712, and banana connector 720 includes a metal terminal 724 and an insulating handle 722. In fig. 7, the banana connector 710 is not yet inserted into the opening 201, and the banana connector 720 is inserted into the opening 206 to electrically connect with the sixth banana socket 226. Next, taking the sixth banana jack 226 as an example, the sixth banana jack 226 includes a metal tube 730 hidden inside the shell 120 and the insulating partition 127 so as to avoid being exposed outside the shell 120 and the insulating partition 127.

In some embodiments, when the banana connector 720 is inserted into the opening 206 to electrically connect to the sixth banana socket 226, preferably, the insulating handle 722 of the banana connector 720 is inserted into the opening 206, and the metal terminal 724 of the banana connector 720 is electrically connected to the metal tube 730 of the sixth banana socket 226, so as to effectively prevent the metal terminal 724 and the metal tube 730 of the sixth banana socket 226 from being exposed outside the housing 120 and the insulating partition 127, thereby effectively increasing the stability and accuracy of measurement, and simultaneously avoiding being interfered by external signals and avoiding the measurement signals from affecting other electronic devices. However, the present invention is not limited thereto, the metal terminal 724 of the banana connector 720 can also be inserted into the opening 206 to electrically connect to the metal tube 730 of the sixth banana jack 226, and the insulating handheld portion 722 of the banana connector 720 covers the insulating partition 127 to shield the metal terminal 724 of the banana connector 720, which does not depart from the spirit and scope of the present invention.

In addition, because the ecg signal connection box 100 of the present disclosure, the chest lead connection module 130 is installed on the second surface 122 of the housing 120, and the limb lead connection module 140 is installed on the third surface 123 of the housing 120, and the second surface 122 is perpendicular to the third surface 123, the length and the volume required by the ecg signal connection box can be effectively reduced, the length of the connection lines can be more consistent, the operation of the measuring personnel is facilitated, and the measurement accuracy is improved. As shown in fig. 2, the distances from the ends of the first banana socket 221, the second banana socket 222, the third banana socket 223, the fourth banana socket 224, the fifth banana socket 225, the sixth banana socket 226, the seventh banana socket 231, the eighth banana socket 232, the ninth banana socket 233 and the tenth banana socket 234 to the hub turntable 266 of the first connector 110 may tend to be consistent, and the distance between the hub turntable and the banana socket is shortened to reduce the maximum length required for the connection wires, so that the variation of signal transmission may be reduced. For example, the first connection line 241, the second connection line 242, the third connection line 243, the seventh connection line 251 and the eighth connection line 252 are all configured to have the same or similar lengths, and the maximum length required for the connection lines is reduced to electrically connect the banana jack and the first connector 110, thereby improving the overall measurement accuracy, but the invention is not limited thereto.
