Description
Technical Field
The invention relates to a brain wave detection technology, in particular to a full-automatic electroencephalogram cap.
Background
The electroencephalogram is a bioelectrical signal generated when neurons of the human brain are active, and has been widely used in clinical medicine. The brain electricity cap is the equipment of being connected with human head in the brain electricity monitoring. In order to obtain high-quality electroencephalogram signals, the electrode sensors of the electroencephalogram equipment must be ensured to have good contact with the skin of the head.
In order to make the electrodes in the electroencephalogram cap communicate well with the brain, the conventional electroencephalogram cap usually needs to be connected with the assistance of liquid or fluid. Among the media commonly used to facilitate communication are saline and fluid conductive pastes:
(1) the electroencephalogram cap communicated by using the physiological saline has the advantages that the operation is simple, the resistance of each electrode does not need to be adjusted one by one, and therefore, the time spent on smoothly communicating all the electrodes is short; the defects of the method are that the communication effect is poor, the resistance is large, and the signal-to-noise ratio is low (as disclosed in patent US20180318584A1, the resistance of an EGI electroencephalogram cap of Net Station company after communication reaches 70k omega).
(2) The electroencephalogram cap using the fluid conductive paste has the advantages that the resistance is low after the electroencephalogram cap is connected, and the signal to noise ratio is high (for example, the resistance after the Neuroscan electroencephalogram cap is connected is 5-10K omega); this has the disadvantage that the resistance of each electrode needs to be adjusted one by one, and the switching efficiency is therefore low. For example, with a 32-lead brain cap acquiring data, preparation may take about 20 minutes, with 85% of the time being used to adjust the resistance. At present, no electroencephalogram cap has the advantages of the two types of electroencephalogram caps (short-time communication is achieved, low resistance is guaranteed, and signal-to-noise ratio is high).
The invention is designed for simultaneously realizing the advantages of the two brain electricity caps.

Detailed Description
The invention is described in detail below with reference to the figures and specific embodiments. It is noted that the aspects described below in connection with the figures and the specific embodiments are only exemplary and should not be construed as imposing any limitation on the scope of the present invention.
As shown in fig. 1, the embodiment of the present disclosure provides a full-automatic electroencephalogram cap, which includes a cap body 1 and a plurality of electrodes 2, the electrodes 2 are uniformly distributed on the cap body 1, each electrode 2 includes a housing 21, a micro-vibration motor (not shown in the figure) and a contact electrode 22, the micro-vibration motor is disposed in the housing 21, and the contact electrode 22 is disposed on a surface of the housing 21 contacting with a brain.
The microseismic motor includes, but is not limited to, a rotor motor or a linear motor, as long as the microseismic motor can drive the electrode 2 to vibrate integrally. When the electroencephalogram cap is just worn on the head of a patient, the contact electrode 22 and the skin may not be in close contact, a proper amount of normal saline is required to be dripped into the vicinity of the electrode or conductive paste is required to be squeezed into the vicinity of the electrode to achieve connection, the electrode 2 is driven by the micro-vibration motor to vibrate integrally, the contact electrode 22 is attached to the skin in vibration, the resistance is reduced gradually, and therefore the electrode and the brain are connected quickly and efficiently.
The contact electrode 22 may be a conventional electrode pad, but a hard electrode pad is not good for the experience of the patient due to the contact with the brain skin of the patient, and therefore, it is preferable that the contact electrode 22 is made of conductive rubber. The contact electrode 22 may be shaped as a convex sphere as shown in fig. 2, or as a structure with multiple contact points as shown in fig. 3, so as to be able to penetrate the patient's hair and ensure good contact with the brain skin when vibrated.
Wherein, the microseismic motor is connected with an external power supply through a lead. Meanwhile, the electrical signal collected by the contact electrode 22 may be connected to an external control circuit in a wired manner and transmitted to the control terminal, or may be transmitted to the control terminal in a wireless manner, for example, a signal transmitter such as a built-in bluetooth transmission module is provided.
The cap 1 is made of a soft material, such as rubber, to better conform to the brain. In this embodiment, the cap body 1 is made of elastic mesh cloth. The electrode 2 can be clamped on the cap body 1 by adopting a rivet clamping structure as shown in fig. 3, so that the disassembly and the position adjustment are convenient.
Further, as the brain wave cap often needs to be upgraded, in a possible embodiment, a detachable upgrade module 3 is provided on the cap body 1. In this embodiment, the upgrade module 3 is disposed at the rear of the cap body 1. When upgrading is needed, the upgrading module 3 can be detached and connected with a computer for upgrading operation.

In addition, as shown in fig. 5, the upgrade module 3 may be provided with a mounting hole 31, so that the upgrade module may be connected to the cap body 1 by using a rivet structure as shown in fig. 6. The rivet 4 penetrates through the cap body 1 from the inner side of the cap body 1 and is inserted into the mounting hole 31 in the upgrading module 3, so that the upgrading module 3 is fixed.
Preferably, a tightening structure (for example, a buckle structure similar to that of a safety helmet) can be further arranged on the upgrading module 3, so that the tightness of the cap body 1 can be adjusted, the hindbrain region can be more fitted to the shape of the head, and the contact is better.
In a possible embodiment, a wireless signal transmission unit is provided inside the upgrade module 3, and the contact electrodes of the respective electrodes 2 are connected with a control circuit in the upgrade module 3. The upgrade module 3 transmits the received brain wave signal to a background computer, and the background computer can control the vibration frequency of the brain electricity cap electrode through the upgrade module. The wireless transmission mode avoids the condition that the wires are messy, and the detection cannot be limited by the length of the wires.
In addition, the upgrading module 3 may further be provided with a data interface 32, such as a USB interface or a type-C interface, for facilitating connection with a device such as a computer for upgrading operation.
