Description
Technical field
This utility model relates to the electrode for encephalograms that uses when a kind of medical brain wave is monitored.
Background technology
At present, the existing bigger progress of electroencephalogram technology in clinical and scientific research, there has been the elastic electrode of use medicated cap to carry out eeg monitoring, but traditional method will be operated by means of the medical care assistant director or through other people that train at present, and the electrode of the conductive paste of in advance having annotated, fixedly the time, can not move again, otherwise conducting solution can overflow and other positions of scalp, especially work as the electrode derivative slightly for a long time, owing to can occur crosstalking between the electrode and more can influence monitoring result, U.S. EGI company has produced a kind of electrode for encephalograms comparatively easily at present, but the conducting solution that it uses is a normal saline.Before using electrode is soaked in normal saline slightly, can install subsequently, but the material that its electrode uses is a kind of hygroscopicity fibre, keeps just having done less than 1 hour through the electrode that soaks, if require the time of monitoring long then impracticable in clinical and the scientific research.In addition, in the eeg monitoring process, often occur because tested patient's somatic movement, head are rocked etc. and to be caused electrode and scalp loose contact, the formation artefact brings inconvenience to clinical judgment, even causes whole eeg data protocol failure.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, makes tested patient can install, carry out voluntarily the filling of conducting solution voluntarily, the electrode for encephalograms of filling voluntarily easy to use, that the eeg monitoring time is long.
Technical solution of the present utility model is: comprise electrode, contact conductor, the conducting solution chamber, it is characterized in that being provided with two skies up and down, be columniform electrical insulator shell all around, be provided with a hand pressure handle in cover top portion, be provided with one in the shell inner chamber is divided into bilevel dividing plate, the non-conductive tower spring of elasticity that withstands hand pressure handle is placed on the dividing plate upper strata, the conducting solution chamber is located between hand pressure handle and the dividing plate, be provided with a conducting solution filler port in dividing plate central authorities, described electrode is placed on the lower floor of dividing plate, its shape is a tower spring shape, and the contact conductor that is connected with electrode is drawn by the fairlead on the shell.
Be provided with blind nut between shell and hand pressure handle, blind nut is pushed down hand pressure handle downwards, and makes that the hand pressure handle zone of action is limited.
The outer ring of described hand pressure handle is wrapped with the sealing rubber ring that prevents that conductive liquid from oozing out.
Described electrode is a silver-silver chloride electrode, and electrode is fixed by the positioning of electrode baffle plate.
Shell is provided with the electrode holddown groove of using when keeping for fixedly, is used for fixing with electrode cap or electrode strap.
The aperture in described filling conducting solution hole is 2mm.
The utlity model has following advantage: (1) tested patient can install electrode for encephalograms voluntarily, carries out the filling of conducting solution voluntarily, need not other people and helps, and is easy to use; (2) tower spring shape electrode body makes the electrode pressurized relatively more balanced, and capacity of resisting disturbance is strong, can monitor brain wave reliably; (3) simple in structure, semienclosed structure makes conducting solution be difficult for evaporation, has prolonged the eeg monitoring time; (4) tested patient can regulate degree of tightness voluntarily, so the no constriction of long-time use.
Description of drawings
Accompanying drawing is the structural representation of this utility model one embodiment.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is further described.
Embodiment 1: in conjunction with the accompanying drawings:
The shell 7 of present embodiment is a plastic cylinder of two skies up and down, internal diameter 13mm, thick 1.1mm, long 18mm, be provided with hand pressure handle 1 at its top, the outer ring of hand pressure handle is wrapped with sealing rubber ring 2, and blind nut 3 is pushed down hand pressure handle downwards and made that the hand pressure handle zone of action is limited; Be provided with a dividing plate 10 in the shell and inner chamber be divided into two-layer up and down, a plastic mast spring 4 is placed on the upper strata, and the tower spring upwards withstands hand pressure handle 1, and the space that forms between hand pressure handle and the dividing plate is conducting solution chamber 13.Dividing plate central authorities are provided with conducting solution filler port 12.The aperture of conducting solution filler port is 2mm.Lower floor is placed with tower spring shape silver-silver chloride electrode 8, and fixing by electrode body positioning baffle 9, and the electrode body that is connected with tower spring shape silver-silver chloride electrode goes between and 6 draws by the fairlead on the shell 5.Also be provided with the electrode holddown groove of using when keeping for fixedly 11 on the shell.
In the present embodiment, conducting solution is thicker, before the use: tested patient can take out blind nut and hand pressure handle earlier,, again hand pressure handle is built to conduction solution cavity 13 injection conductive pastes by conducting solution filler port 12, blind nut 3 is pushed down hand pressure handle downwards, after head cleaned up, electrode holddown groove 11 is fixed on electrode cap or the electrode strap, at head-mount and have good positioning, carries out eeg monitoring again.
Because electrode body is a tower spring shape, when electrode wear appropriate after, substantially be compressed in the shell lower layer space, make that like this contacting of electrode body and scalp is good, interference such as rock that can excuse portion makes electrode and scalp loose contact, head external force such as rock all owing to the tower spring tension force of electrode body is released.This moment patient's pressure hand pressure handle that press...withes one's finger, hand pressure handle is stressed to move down, and conducting solution chamber volume is dwindled, internal pressure increases, solution flows out from filler port, is full of between scalp and the electrode, can realize the measurement to electroencephalogram.Because the existence of conducting solution intracavity tower spring, when hand pressure handle is stressed when moving down, this moving process has certain damping, makes conducting solution slowly rather than filling rapidly, has avoided the injection of solution; After filling finished, the tension force of tower spring made and makes things convenient for filling once more by the hand pressure handle self-return.
Embodiment 2:
In the present embodiment, conducting solution is rarer, as normal saline.In the present embodiment, the conducting solution intracavity is put the stronger sponge of water absorption, wraps up with absorbent cotton below the shell.Surplus with embodiment 1.
