[0028] This invention proposes an amplifier box 1000 for use in a neurophysiological monitoring instrument, which has a first signal interface and a second signal interface.

[0029] Please see Figure 1In one embodiment of this utility model, the amplification box 1000 includes a housing 1 and an amplification circuit board; the housing 1 has a receiving cavity, and the housing 1 forms a through hole 101 that connects the receiving cavity to the outside; the amplification circuit board is disposed in the receiving cavity, and the amplification circuit board is provided with a four-channel electrode interface 2 and a signal output port. The four-channel electrode interface 2 is exposed in the housing 1, and the signal output port is disposed near the through hole 101. The four-channel electrode interface 2 is used to connect the acquisition electrode, and the signal output port is used to electrically connect to the first signal output port or the second signal interface through a signal cable.

[0030] In this invention, the amplification circuit board is placed inside a separate housing 1. The signal output port of the amplification circuit board is electrically connected to the neurophysiological monitor via a signal cable to transmit electrical signals. This makes the electrode connection and the adjustment of the position of the amplification box 1000 more flexible and convenient to use. The four-channel electrode interface 2 of the amplification circuit board can connect to an integrated electrode, which consists of four electrodes, thus receiving signals from four electrodes and increasing the diversity and comprehensiveness of signal acquisition.

[0031] To improve monitoring efficiency, please refer to one embodiment of this utility model. Figure 1 The amplifier circuit board has four four-channel electrode interfaces 2, which are arranged in a rectangular array. This arrangement allows the amplifier box 1000 to simultaneously receive signals from sixteen channels, resulting in higher signal acquisition efficiency. The rectangular array of the four four-channel electrode interfaces 2 effectively utilizes space, making the amplifier circuit board more compact, facilitating circuit design optimization, reducing electromagnetic interference between different channels, and improving signal stability and accuracy.

[0032] Understandably, since the neurophysiological monitor has a first signal interface and a second signal interface, and different signal interfaces receive electrical signals from different parts of the human body, after both interfaces of the neurophysiological monitor are connected to the amplifier box 1000, medical personnel need to confirm which signal interface the amplifier box 1000 is electrically connected to when inserting the integrated electrode. Therefore, in one embodiment of this utility model, the amplifier box 1000 also includes an indicator device. The indicator device is located in the housing 1, near the signal output port, and electrically connected to the amplifier circuit board. The indicator device is used to indicate which signal interface the amplifier box 1000 is connected to in the neurophysiological monitor. That is, through the indicator device, medical personnel can easily determine the signal interface to which the amplifier box 1000 is electrically connected, without needing to make a manual judgment. This reduces the probability of incorrect connection when connecting the amplifier box 1000 and the integrated electrode. Incorrect connection will lead to abnormal data from the neurophysiological monitor, making it impossible to collect accurate data, which will in turn affect the medical personnel's judgment.

[0033] Specifically, in one embodiment of this utility model, please refer to Figure 1 The indicating device is a digital display screen 3, which can display the connection status of the amplifier box 1000. When the amplifier box 1000 is connected to the first interface of the neurophysiological monitor, the digital display screen 3 can display the number "1"; when the amplifier box 1000 is connected to the second interface of the neurophysiological monitor, the digital display screen 3 can display the number "2". This clearly shows the connection status of the amplifier box 1000. In other embodiments, the indicating device can be an LED indicator light or a signal light, as long as it can indicate the connection status of the amplifier box 1000.

[0034] Furthermore, in one embodiment of this utility model, please refer to... Figure 1 The amplifier circuit board also includes a ground interface 4, which is exposed within the housing 1 and used to connect to the ground wire. The ground interface 4 allows the amplifier box 1000 to be directly connected to the ground wire, helping to maintain the signal reference point in the circuit and ensuring signal accuracy and stability. Similarly, in another embodiment of this invention, please refer to... Figure 1 The amplifier circuit board also features a reference line interface 5, which is exposed within the housing 1 and used to connect reference lines. The reference line interface 5 allows the amplifier box 1000 to be directly connected to reference lines, providing a fixed signal reference point and contributing to improved signal accuracy and stability. Furthermore, when the amplifier box 1000 simultaneously features a ground interface 4 and a reference line interface 5, corresponding indicator labels can be used to distinguish between them.

[0035] For ease of assembly and maintenance, please refer to one embodiment of this utility model. Figures 1 to 3 The housing 1 includes an upper housing 11 and a lower housing 12, which are detachably connected and together form a receiving cavity. This detachable design makes the assembly and maintenance of the amplifier box 1000 more convenient. No special tools are required to open the housing 1 for inspection or replacement of internal components. Furthermore, this design makes it easier and faster to upgrade or replace the amplifier circuit board or other internal components.

[0036] Specifically, in one embodiment of this utility model, please refer to Figure 2 and Figure 3The upper shell 11 and the lower shell 12 are fastened together. The upper shell 11 has a fastening part 113, and the lower shell 12 has a mating part 121. The fastening part 113 can fasten onto the mating part 121 to achieve a detachable connection between the upper shell 11 and the lower shell 12. Multiple fastening parts 113 and mating parts 121 can be provided to improve the stability of the connection. In another embodiment of this utility model, the upper shell 11 and the lower shell 12 are connected by screws. The screw connection can withstand repeated disassembly and assembly, improving the durability and reliability of the shell 1. Furthermore, the upper shell 11 and the lower shell 12 can be connected by screws after the fastening connection, making the connection even more stable.

[0037] Furthermore, in one embodiment of this utility model, please refer to... Figure 1 and Figure 2 The upper shell 11 has a receiving groove 111, and a through hole 112 is formed at the bottom of the receiving groove 111. The through hole 112 connects the receiving groove 111 to the receiving cavity, and the four-channel electrode interface 2 passes through the through hole 112 and is accommodated in the receiving groove 111. The design of the receiving groove 111 and the through hole 112 formed in the upper shell 11 allows the four-channel electrode interface 2 to pass directly through the through hole 112 and be accommodated in the receiving groove 111. This compact layout helps to reduce the overall volume of the amplifier box 1000. At the same time, by accommodating the electrode interface in the receiving groove 111, the interface can be protected from external damage and its service life can be extended. In addition, by setting the shape of the receiving groove 111, the integrated electrode can be limited and guided during the insertion of the integrated electrode, ensuring the stability of the connection.

[0038] For ease of use, please refer to one embodiment of this utility model. Figure 3 The amplifier box 1000 also includes a mounting part 6, which is located at the end of the housing 1 furthest from the signal output port. In actual use, the mounting part 6 can be installed with a corresponding hook at the side of the operating table or other locations to improve space utilization. Furthermore, the fact that the mounting part 6 is located at the end of the housing 1 furthest from the signal output port does not affect the connection of the amplifier box 1000 to the neurophysiological monitor through the signal output port.

Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
