[0002] Anesthesia is an essential and critical step in modern clinical surgery, but its implementation carries a high risk. Incorrect anesthetic dosages can cause harm to patients. Providing safe and reliable anesthesia for patients is currently a key topic in anesthesia research. EEG signals are a comprehensive reflection of changes in synaptic potentials in the cerebral cortex, with the advantages of reflecting conscious activity and being non-invasive. EEG signals are currently one of the most promising methods for objectively assessing the depth of anesthesia, and promising research results have been achieved. Using EEG signals to assess the anesthetic state during clinical surgery has important clinical application value. Therefore, acquiring EEG signals is crucial for monitoring the depth of anesthesia.

[0003] Currently, the electrode sensors commonly used to obtain EEG signals mainly transmit the sensor signals to the EEG electrode monitor through the EEG sensor connector. In related technologies, the EEG sensor connector abuts the sensor through a convex button and two springs. By pressing, the two overlapping springs abut the head and tail ends of the sensor respectively. If the pressing force of the convex button is set improperly, it may result in a greater force being required to abut the sensor during operation. Utility Model Content

[0034] The utility model provides an electroencephalogram sensor connector.

[0035] See also Figure 1 and Figure 2 In one embodiment of the present utility model, the EEG sensor connector includes a housing 1, a switch 2, a spring assembly 3 and a circuit board 4. The housing 1 is provided with a cavity and a first groove 11 arranged at intervals; the switch 2 is rotatably arranged in the first groove 11; the spring assembly 3 includes a first spring 31 and a second spring 32. The first spring 31 has a driving end located in the first groove 11 and a limiting end that movably passes through the bottom wall of the first groove 11 and extends into the cavity; one end of the second spring 32 is connected to the inner wall of the first groove 11, and the other end of the second spring 32 abuts against the switch 2, and exerts a force on the second spring 32 that is directed back to the first groove. The circuit board 4 is arranged on the bottom wall of the cavity facing the first cavity 11, and the limit end is extended toward the circuit board 4; a plug-in channel 313 for the EEG sensor to pass through is formed between the circuit board 4 and the limit end; the EEG sensor connector has a first state in which the driving end is in contact with the switch 2, and a second state in which the driving end is disengaged from the switch 2; when the switch 2 rotates relative to the housing 1, the EEG sensor connector switches between the first state and the second state; the opening area of the longitudinal section of the plug-in channel 313 in the first state is larger than the opening area of the longitudinal section of the plug-in channel 313 in the second state.

[0036] In this embodiment, the EEG sensor connector is used for an EEG sensor to monitor the patient's EEG activity scene. The cavity is used to accommodate the entire shell 1, the first groove 11 is used to limit the switch 2, the first spring 31 is an elastic element for maintaining the position of the switch 2, and the second spring 32 is an elastic element that uses the properties of elastic material to achieve pressing and resetting actions. The switch 2 is used to fix the plug and plug in and out the plug, and the switch 2 is arranged in a boat shape. The driving end is the end of the first spring 31 that receives the force applied by the switch 2, and the plug-in channel 313 is used for the EEG sensor to pass through. The circuit board 4 is configured to have an encryption function. Accordingly, when assembling the EEG sensor connector, first fix the second spring 32 to the shell 1, then fix the first spring 31 to the shell 1, and then press the switch 2 into the shell 1, and the circuit board 4 is fixed to the bottom wall of the shell 1. At this time, the position of the first spring 31 can be changed by adjusting the position of the switch 2.

[0037] Furthermore, when the outside world presses the switch 2 downward, that is, the second state in which the driving end is disengaged from the switch 2, the switch 2 applies a downward force to the second spring piece 32, while the first spring piece 31 is not subjected to the downward force applied by the switch 2 at this time. The first spring piece 31 bounces up, and the EEG sensor connector can be pulled out at this time; and when the outside world does not apply force to the switch 2, that is, the first state in which the driving end is in contact with the switch 2, the second spring piece 32 continues to abut against one end of the switch 2 upward due to its own elastic properties, and the end of the corresponding switch 2 away from the abutment of the second spring piece 32 will abut against the first spring piece 31 downward. At this time, the first spring piece 31 is subjected to a downward force, and the first spring piece 31 will abut against the EEG sensor under the action of the force, thereby achieving the effect of fixing the EEG sensor.

[0038] The technical solution of the present invention is to set a switch 2 on the shell 1, and the switch 2 abuts the first spring piece 31 and the second spring piece 32 respectively; when the driving end is in the second state of being disengaged from the switch 2, the first spring piece 31 is not subjected to the force and bounces upward. At this time, the longitudinal cross-sectional opening area of the plug-in channel 313 is relatively large, and the matching EEG sensor can be easily removed; when the driving end is in the first state of abutting the switch 2, the second spring piece 32 continuously abuts the switch 2, and the second spring piece 32 always presses upward against the switch 2. At this time, the longitudinal cross-sectional opening area of the plug-in channel 313 is relatively small, and the EEG sensor can be easily inserted into the EEG sensor connector, thereby achieving the effect of fixing the EEG sensor; the above-mentioned setting method makes plugging and unplugging more labor-saving and more convenient to operate, which greatly facilitates the operation of the operator.

[0039] In one embodiment of the present invention, the first spring piece 31 has a first straight section 311 and a first limiting section 312. The driving end is located in the first straight section 311, and the limiting end is located in the first limiting section 312. The first straight section 311 and the first limiting section 312 are integrally formed. The first straight section 311 has first openings 315 at both ends of its surface. The end of the first limiting section 312 away from the first straight section 311 is bent upward. Figures 3 and 4 In this embodiment, the first straight section 311 is in contact with the switch 2, the first limiting section 312 is in contact with the EEG sensor, and the first opening 315 is used to secure the first spring 31. The upwardly curved tail end of the first limiting section 312 helps better conform to the shape of the EEG sensor and provide better contact with the EEG sensor.

[0040] In one embodiment of the present invention, the first elastic member 31 further comprises a second limiting section 314. The first straight section 311 extends outward toward one end of the second elastic member 32 to form the second limiting section 314. The second limiting section 314 connects to the first straight section 311 and is fixed to the bottom wall of the first receiving groove 11. In this embodiment, the second limiting section 314 is used to limit the movement of the first elastic member 31 when the switch 2 is disengaged from the first elastic member 31. This arrangement helps prevent excessive movement or deflection of the first elastic member 31 when disengaged, reducing potential risks associated with improper elastic member movement.

[0041] In one embodiment of the present invention, the second elastic piece 32 has a second straight section 321 and a third limiting section 322. The third limiting section 322 and the second straight section 321 are integrally formed. The connection between the second straight section 321 and the third limiting section 322 is arc-shaped. The second straight section 321 has a second opening 324 at both ends of its surface. Figures 3 to 4 In this embodiment, the second straight section 321 is fixed to the bottom wall of the first receiving groove 11, the third limiting section 322 is in contact with the second end of the switch 2, and the second opening 324 is used to fix the second spring 32. The arc-shaped connection increases the elasticity of the spring, allowing it to provide better force feedback when pressed. At the same time, it allows the switch 2 to continue to abut against the switch 2 in the absence of external forces, continuously applying upward force to the switch 2, thereby maintaining the balance of the entire structure.

[0042] In one embodiment of the present invention, the second spring piece 32 further comprises a fourth limiting section 323. The second straight section 321 extends in a direction close to the bottom wall of the first receiving groove 11 to form the fourth limiting section 323. The second straight section 321 connects to the fourth limiting section 323. The fourth limiting section 323 is arranged at an angle to the second straight section 321. The fourth limiting section 323 movably penetrates the bottom wall of the first receiving groove 11 and extends into the receiving cavity. In this embodiment, the fourth limiting section 323 is used to limit the movement of the second spring piece 32. Furthermore, the fourth limiting section 323 is arranged at an angle to the second straight section 321, forming a generally L-shape. This arrangement achieves more precise spatial positioning and more stable structural support, reduces displacement or deformation caused by external forces, and enhances the stability of the overall structure.

[0043] In one embodiment of the present invention, a mounting hole is defined on the sidewall of the first recess 11 facing away from the pressing direction of the switch 2. A connecting block is formed on the sidewall of the switch 2 facing the first recess 11. The connecting block is adapted to fit within the mounting hole so that the connecting block can be pivotally connected to the mounting hole. In this embodiment, the pivotable connection of the connecting block to the mounting hole facilitates achieving two possible motion states of the switch 2, ensures a tight fit between the connecting block and the mounting hole, provides a stable connection, and reduces structural loosening caused by improper connection.

[0044] In one embodiment of the present invention, a plurality of protrusions are formed on the bottom wall of the first receiving groove 11, each of which is respectively inserted into the first opening 315 and the second opening 324. In this embodiment, the insertion of the protrusions into the openings ensures a secure connection between the first spring clip 31 and the second spring clip 32, while also ensuring that the first spring clip 31 and the second spring clip 32 are correctly positioned within the first receiving groove 11, preventing movement or offset.

[0045] In one embodiment of the present invention, the housing 1 comprises an upper shell and a lower shell. The upper shell has an opening for the EEG sensor to pass through and a retaining groove for the lower shell to engage. The sidewalls of the lower shell form retaining projections that engage the retaining grooves. In this embodiment, the upper and lower shells are connected by a snap-fit connection, ensuring a secure connection between the upper and lower shells. The opening provides space for the EEG sensor to extend into, ensuring precise positioning and insertion. This arrangement also simplifies the assembly process.

[0046] The present invention also proposes an EEG sensor, which includes a sensor body and an EEG sensor connector. The specific structure of the EEG sensor connector refers to the above-mentioned embodiment. Since the EEG sensor adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here. Among them, the sensor body is electrically connected to the circuit board 4 of the EEG sensor connector. In this embodiment, the circuit board 4 is a bridge between the sensor body and the EEG sensor connector. Through the electrical connection of the circuit board 4, high-efficiency signal transmission from the EEG sensor to the data processing unit is achieved, reducing signal loss and delay; and also providing greater flexibility.

[0047] In one embodiment of the present invention, a second recess 2100 is formed on the end of the sensor body facing the EEG sensor connector, and the first spring clip 31 of the EEG sensor connector is snap-fitted into the second recess 2100. In this embodiment, the second recess 2100 serves to provide a guide and limit point for the EEG sensor connector, ensuring that the sensor body is positioned by the first spring clip 31 of the EEG sensor connector, making installation and removal quicker and more convenient.
