Description
Technical Field
The utility model belongs to the field of medical appliances, in particular to a portable device for dynamic electroencephalogram acquisition.
Background
The dynamic electroencephalogram is an electroencephalogram examination method for recording the electroencephalogram activity of a patient for a long time by carrying an electroencephalogram examination instrument with the patient for 24h, and can observe continuous electroencephalograms of the patient in various conditions including eating, sleeping, walking and the like in one day. Because the ordinary electroencephalogram is only monitored for about twenty minutes, and many patients are not in the epileptic seizure period at that time, abnormal epileptic brain waves are probably not monitored, the dynamic electroencephalogram monitoring time is long, the detection rate of the abnormal brain waves of the epileptic patients can be greatly improved, and especially the abnormal epileptic brain waves appearing in the sleeping process are easier to detect by the dynamic electroencephalogram.
A typical dynamic electroencephalograph acquisition includes two parts, one being acquisition electrodes disposed on the head of a patient, and the other being an electroencephalograph. The conventional electroencephalograph recorder is carried around in a bag or a pocket. However, this results in a long connection between the acquisition electrodes and the electroencephalograph, and the electroencephalogram typically has 21 wires, which may result in the wires becoming entangled. Since the electroencephalograph is generally far from the head, the connecting wire is easily touched by the arm during the daily activities of the patient, so that the connecting wire may be unstable or fall off, which affects the acquisition of the electroencephalogram signals.

The arc-shaped elastic shell 1 is sleeved on the neck of a patient, and the opening is positioned in front of the neck of the patient. The power supply module is arranged at one end inside the arc-shaped elastic shell 1 and is electrically connected with the electroencephalogram recording module.
The electroencephalogram recording module is arranged in the arc-shaped elastic shell 1 and is electrically connected with the electroencephalogram collecting electrode. The electroencephalogram recording module includes: a collection electrode connecting port 5, a reference electrode module 4 and an electroencephalogram recorder. The collecting electrode connecting port 5 is arranged on the upper surface of the middle position of the arc-shaped elastic shell 1 and is used for connecting an electroencephalogram collecting electrode. The collecting electrode connecting port 5 is provided with a plurality of lead connecting ports 52, and the lead connecting ports 52 are provided with 5 rows and 5 columns. The arrangement of the lead connecting ports 52 in 5 rows and 5 columns can make the connection of medical staff more convenient and the situation of connection errors is not easy to occur. The collecting electrode connecting port 5 is provided with a flexible protective plate 51 on the side surface close to the outer arc surface of the arc-shaped elastic shell 1. The flexible protection board 51 can prevent the patient from extruding the connecting terminal in the lying state, and the unstable connection condition occurs.
The electroencephalogram recorder is arranged at the other end inside the arc-shaped elastic shell 1, is electrically connected with the power supply module, is electrically connected with the acquisition electrode connecting port 5 and is electrically connected with the reference electrode module 4. Two ends of the arc-shaped elastic shell 1 are respectively provided with a charging port 2 and a data leading-out port 3, and the data leading-out port 3 is electrically connected with an electroencephalogram recorder. The charging port 2 is electrically connected to the power module.
As shown in fig. 1, 2 and 3, the reference electrode modules 4 are mounted on two side edges of the arc-shaped elastic shell 1, and penetrate through the upper surface and the lower surface of the arc-shaped elastic shell 1 to be slidably connected with the arc-shaped elastic shell 1. The reference electrode module 4 includes: reference electrode sheet 41, support bar 44, spring 42, ratchet fitting structure 45 and key cap 46. The reference electrode pad 41 is disposed on the lower surface of the arc-shaped elastic casing 1 for contacting the neck skin of the patient and electrically connected with the electroencephalograph. One end of the support rod 44 is fixedly connected with the reference electrode plate 41. The support bar 44 is provided with a limit table 43. The spring 42 is sleeved on the support rod 44 and positioned between the limit platform 43 and the reference electrode plate 41, one end of the spring is abutted against the limit platform 43, and the other end of the spring is abutted against the arc-shaped elastic shell 1. One end of the ratchet wheel matching structure 45 is connected with the other end of the support rod 44 in a sliding mode. The key cap 46 is located on the upper surface of the arc-shaped elastic shell 1 and detachably connected with the other end of the ratchet matching structure 45.
According to the electroencephalogram recorder, the electroencephalogram recorder is arranged in the arc-shaped elastic shell 1 and fixed on the neck of a patient, the distance between the electroencephalogram recorder and a collecting electrode is reduced, the length of a wire is reduced, the problem that the connecting wire falls off due to the fact that the connecting wire is touched in daily activities is avoided, and the problem that the connecting wire is knotted is also avoided. The reference electrode module 4 is arranged in the arc-shaped elastic shell 1, so that the number of electrodes arranged on the head is reduced, namely the number of connecting wires is reduced, and the misconnection rate of medical staff when connecting the acquisition electrodes with the electroencephalogram recording module is reduced.
In particular, in use, a medical staff coats the coupling agent on the reference electrode sheet 41, and then the arc-shaped elastic shell 1 is sleeved on the neck of a patient, so that the opening of the arc-shaped elastic shell 1 is positioned at the chest of the patient. The connecting wires of the collecting electrodes are then connected to the wire connecting ports 52. After the connection of the connection line is completed, the key cap 46 is pressed down, and under the action of the ratchet wheel matching structure 45, the reference electrode sheet 41 is attached to the neck skin of the patient and used as a reference electrode. After finishing collecting, medical personnel can export the data in the electroencephalograph through the data export port 3 to charge the power module through the charging port 2.
Because electroencephalograph and power supply module are located at two ends of the arc-shaped elastic shell 1, the center of gravity of the whole arc-shaped elastic shell 1 faces the chest direction of a patient, so that the user-type elastic shell can not move backwards, and the position of the reference electrode plate 41 can be well fixed.
The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the scope of the embodiments of the present invention, and are intended to be covered by the claims and the specification.
