Problems solved by technology

[0009] The purpose of the present invention is to provide a convenient enhanced conductive paste injector to solve the time-consuming defects of the current experiment proposed by the above-mentioned background technology due to the time-consuming injection of conductive paste to the electrodes of the EEG cap. The uneven application caused by the injection of the conductive paste, the repeated application of the conductive paste leads to the waste or even excess of the conductive paste, which leads to the phenomenon of short circuit conduction of the electrodes. Causes problems such as difficulty in reducing impedance

Embodiment 1

[0083] Combine Figure 1-2 It is shown that, first tighten the flat head tube 2 of the material of 304 stainless steel and the needle interface interface 3. The main shape of the flat head tube 2 is a hollow cylindrical structure. Quality plastic, there is a thread bayonet setting, so the specific operation method is to tighten the top of the flat head tube 2 and the inner wall of the thread 3 of the needle interface interface 3 to achieve the purpose of fixing the flat head tube 2 to the duct 4, so that the two constitute the two constitute Over -earning cooperation. Such a setting is convenient for the single -rooted guide in the later period, and the single -rooted replacement does not need to replace the entire syringe.

Embodiment 2

[0085] Silicone holes 6 is made of silicone, which is located on the hat -shaped round surface of the hat -shaped mechanism. In the grooves of the silicone holes 6, the two constitute the bumps to fix the duct device on the hat -shaped structure 5.

[0086] This embodiment needs to be repeatedly executed until all catheter installation is successful.

Embodiment 3

[0088] The syringe (syringe 11 and the syringe piston 12 are hard plastic, and the syringe syringe 11 and the catheter solid device 8 constitute a violin combination; The outer side of the 12 is fitted with the inner wall of the syringe syringe 11, and the syringe piston 12 and the syringe syringe 11 constitute the bump.

Abstract

The invention belongs to the technical field of conductive paste injectors, and discloses a portable enhanced conductive paste injector which is characterized in that the lower end of a special needle tube type injector is connected with a cap-shaped structure guide device through an injection port; the special tubular injector is provided with an injection port, a cylinder body and a handle, the injection port can be combined with a port of the cap-shaped structure guide device, and the cylinder body and the handle are fixed at the rear end of the injection port; the cap-shaped structure guiding device comprises a catheter, an injection port and a cap-shaped fixer; one end of the catheter is fixed on the cap-shaped fixer according to the arrangement sequence of the electrodes on the electroencephalogram cap and penetrates through the fixer, and the other end of the catheter is gathered towards the port. Scales are printed on the outer surface of the cylinder body opening; the handle is in a pistol shape, and the injection port is provided with a piston. The multiple catheters are used, injection work of multiple electrodes can be conducted at the same time, the number of times of injection is reduced, scales are printed on the outer wall of the syringe cylinder body, use amount control is facilitated, operation of experimenters is facilitated, time consumption is reduced, and adjustment of operators is facilitated.

Description

Technical field [0001] The invention is the field of conductive cream syringe technology, and especially involves a convenient enhanced conductive ointment syringe. Background technique [0002] At present, with the development of brain electrical technology, the application of EEG in daily life and scientific research is becoming more and more common. Electrical and electrical experiments responsible for collecting EEG are widely used in clinical medical diagnosis, psychological research, neuroscience and other fields. [0003] The collection system of Electricity signals on the market has stem electrode, wet electrode and special electrode. Although the stem electrode saves effort in the preparation stage of the experiment, the signal quality collected is not as good as the moist electrode. Special electro -electrodes are mostly used to test some special locations. It can be seen that the wet electrical electric stance in the Electrical Electricity experiments has greater appli...
