Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a tail line connection box and a terminal system. Background Art

[0002] The electrical signals directly output through the conduit are often affected by the use environment. This is because even if the conduit end is grounded and the wires are twisted to eliminate power frequency interference, the signal transmitted through the tail line will still be affected by the strong electromagnetic field. In order to achieve better signal transmission effects, the tail line end is often connected in series or in parallel with an appropriate inductor in the key signal transmission circuit. If necessary, a filtering circuit and a shielding shell must be added to stabilize the current, eliminate noise and prevent interference for the transmitted signal. In this way, the electrical signal processed by the optimized circuit can be better transmitted to the equipment terminal.

[0003] However, using two wires (one copper wire and one copper-nickel wire) to transmit ECG signals and temperature signals at the same time and displaying them on the panel at the same time is a challenge, especially for T-type thermocouple temperature sensors. This is because when the catheter tip discharges, one of the copper wires is used to output ECG signal information, and the other copper-nickel wire has a great interference with the signal due to the "antenna effect". The T-type thermocouple temperature sensor cannot remove this copper-nickel wire, otherwise the sensor will not work. This results in the inability to display ECG signals and temperature signals at the same time when outputting signals using this method. Utility Model Content

[0031] [Example 1]

[0032] See also Figure 1 The present embodiment provides a tail wire connection box, comprising: a box body 1 and a signal separation circuit 2, wherein the signal separation circuit 2 is arranged in the box body 1 and is used to be connected to the electrical output end of the electrophysiological catheter, and the signal separation circuit 2 has an ECG signal transmission mode and a temperature signal transmission mode. The signal separation circuit 2 is configured to transmit the ECG signal output by the electrophysiological catheter when the ECG signal transmission mode is turned on, and to transmit the temperature signal output by the electrophysiological catheter when the temperature signal transmission mode is turned on.

[0033] The tail line connection box further comprises a switching switch 3 , which is arranged in the box body 1 . The switching switch 3 switches the electrocardiogram signal transmission mode and the temperature signal transmission mode of the signal separation circuit 2 to be switched on by switching the position.

[0034] This embodiment provides a manual tail wire connection box, that is, the signal separation circuit 2 realizes mode switching through manual operation, and the tail wire connection box also includes a driving member 4, which is connected to the switching switch 3 and partially extends out of the box body 1, and the driving member 4 is used to drive the switching switch 3 so that the position of the switching switch 3 changes.

[0035] The top wall of the box body 1 has a through hole 111, and part of the driving member 4 extends from the through hole 111 into the box body 1 to be connected with the driving member 4, while the other part of the driving member 4 remains outside the box body 1 for manual operation.

[0036] The top of the box body 1 is provided with (e.g., set by silk screen) effective information of switch switching (not shown in the figure) for prompting the user, such as "WeChat signal" and "multi-channel temperature measurement" signs are provided on the top wall of the box body 1. When the driving member 4 moves to the "WeChat signal" position, the ECG signal transmission mode is turned on, and when the driving member 4 moves to the "multi-channel temperature measurement" position, the temperature signal transmission mode is turned on. In order to facilitate the setting of the signs, a transparent cover plate 5 can be set on the top of the box body 1, and the transparent cover plate 5 can be set on the top of the box body 1 in an embedded manner.

[0037] It can be seen that in this embodiment, the driving component 4, the switching switch 3 and the signal separation circuit 2 form a linkage module. When the power and signal are turned on, the driving component 4 is driven to enable the tail line connection box provided in this embodiment to switch between two signal transmission modes.

[0038] Optionally, the driving member 4 may be a knob or a dial, the switching switch 3 may be a six-section switch, and the signal separation circuit 2 may adopt a PCB board circuit, which may also optimize the processing of the signal.

[0039] Preferably, the box body 1 adopts a detachable structure, including an upper shell 11 and a lower shell 12, wherein the upper shell 11 can be opened and closed and arranged on the lower shell 12, and the two can be snap-connected. The two opposite side walls of the lower shell 12 have mounting interfaces 121, and the mounting interfaces 121 can be used to embed a socket or a cable plug for electrical connection between the tail wire connection box and the tail wire of the electrophysiological catheter and other equipment.

[0040] Preferably, the bottom of the lower shell 12 has a rubber pad 122 , and the rubber pad 122 can be embedded in the bottom of the lower shell 12 to play an anti-slip role.

[0041] [Example 2]

[0042] See also Figure 2, which is different from the first embodiment, this embodiment provides a CNC connection box. Specifically, the tail line connection box provided in this embodiment does not include the driving member 4, but includes a relay 6. The relay 6 is used to control the switching switch 3 to switch positions at a target speed so that the ECG signal transmission mode and the temperature signal transmission of the signal separation circuit 2 are synchronously turned on.

[0043] The relay 6 can be connected to the signal separation circuit 2, and by quickly driving the switching switch 3, the ECG signal information and the temperature information can be displayed simultaneously.

[0044] Optionally, in this embodiment, the tail wire connection box further includes a display panel 7, and the display panel 7 is used to display ECG signal information and temperature information. Since the drive member 4 is not required in this embodiment, the display panel 7 can be disposed on the top of the upper housing 11, and the through hole 111 of the upper housing 11 is used for routing the display panel 7.

[0045] It can be seen that in this embodiment, the relay 6, the switching switch 3, the signal separation circuit 2 and the display panel 7 constitute a linkage module. When the power and signal are turned on, the relay 6 quickly distinguishes the switching position of the switching switch 3, so that the tail line connection box provided in this embodiment can switch between two signal transmission modes.

[0046] [Example 3]

[0047] For some signal processing devices, due to functional limitations, they cannot receive ECG signals and temperature signals at the same time. Therefore, in Embodiment 1 and Embodiment 2, when transmitting signals, the two modes are switched so that the ECG signals and temperature signals are respectively transmitted to the signal processing device through the same signal transmission channel.

[0048] See also Figure 3 , which is different from the above-mentioned embodiment, the tail wire connection box provided in this embodiment does not include a switching switch 3. In this embodiment, the electrocardiogram signal and the temperature signal are transmitted to the terminal in a dual-channel parallel direction through the signal separation circuit 2. When the tail wire connection box adopts this design, it is only necessary for the signal processing device to be able to synchronously receive the two signals.

[0049] Compared with the first and second embodiments, although the signal processing device has higher performance requirements, the tail wire connection box provided in this embodiment can be designed to be smaller. In order to facilitate taking, a handle 8 can be provided on the box body 1 of the tail wire connection box.
