Embodiment 1

[0046] Please refer to figure 1 and figure 2 , figure 1 It is a block diagram of a wearable experimental animal 1 EEG acquisition device of the present invention. figure 2 It is a schematic structural diagram of the use state of a wearable experimental animal 1 EEG acquisition device of the present invention. A wearable experimental animal 1 EEG collection device. Described EEG collection device comprises the EEG recording electrode 13 that is connected at head 11, and described EEG recording electrode 13 establishes connection with signal collector 14 by transmission line 16; Described signal collector 14 is fixed on experimental animal. 1 on the vest 2 worn; the other end of the signal collector 14 is connected to the signal receiver 15.

[0047] Please refer to image 3 and Figure 4 , image 3 It is a schematic diagram of the structure of the inner surface of the vest 2. Figure 4 It is a schematic diagram of the structure of the outer surface of the vest 2. The...

Embodiment 2

[0052] This embodiment is basically the same as Embodiment 1, the difference is: please refer to Figure 5 , Figure 5 It is a schematic diagram of the outer surface structure of another vest 2 of the present invention. A schematic diagram of the outer structure of the vest 2. The outer surface of the vest 2 is also provided with a signal collector fixed body 29 and a signal receiver fixed body 291; the signal collector fixed body 29 is used for fixing the signal collector 14, and the described signal receiving fixed body is used for Fixed signal receiver 15.

[0053] In this embodiment, the fixed effect of the signal collector fixed body 29 and the signal receiver fixed body 291 is exact. Compared with the fixed belt used to fix the signal collector 14 and the signal receiver 15 in the embodiment, it is not easy to slip, and each The interfaces of the components are tightly connected.

Abstract

The invention provides a wearable experimental animal electroencephalogram collection device comprising an electroencephalogram recording electrode connected to a head; the electroencephalogram recording electrode establishes connection with a signal collector via a transmission line; the signal collector is fixed on a waistcoat worn by an experimental animal; the other end of the signal collector establishes connection with a signal receiver; the waistcoat is provided with a first upper limb passing hole and a second upper limb passing hole; the inner surface of one end of the waistcoat is provided with a hook-and-loop fastener hook component and the outer surface of the other end of the waistcoat is provided with a hook-and-loop fastener loop component; the hook-and-loop fastener hook component is fastened to the hook-and-loop fastener loop component; the waistcoat is provided with a positive V-shaped circular arc section and an inverse V-shaped circular arc section. The wearable experimental animal electroencephalogram collection device is small in size and light in weight, reduces stress on the head of an experimental animal and is conducive to wound healing; detection workers can control the device conveniently; an electroencephalogram signal collection process is not liable to be disturbed by external environment, so that the collection of electroencephalogram signals of an experimental animal can last for a long time.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a wearable experimental animal EEG acquisition device. Background technique [0002] In the experimental research of experimental animals in the field of life sciences, the collection and monitoring of experimental animal EEG signals, as a basic part of experimental animal neuroelectrophysiological research, has always been a very important technology. The electrophysiological activity of brain nerve cells produces electrical phenomena on the surface of the cerebral cortex or scalp. EEG signals contain a lot of physiological and disease information. Medical experiments often collect EEG signals from animals in order to analyze diseases and provide diagnostic basis. [0003] At present, the EEG acquisition devices for experimental animals are all fixed on the skull together with recording electrodes, signal receivers and transmitters. There are following deficiencies and ...
