In the whole process, the tape is required to be dragged and pressed to carry out a series of comparison, measurement, calculation and marking on the head of the patient. The electrode placement position determining process generally needs double cooperation, is very complicated, and is easy to form deviation in the operation process. Wherein,

While the present specification describes and describes the preferred embodiments of the present invention, it will be appreciated by those skilled in the art that limited changes, modifications and variations to these embodiments may be considered equivalent variations to those described in the present invention, and which are intended to be within the scope of the claims.

In one embodiment of the measuring device, fig. 3 shows a measuring device for determining the electrode placement position of scalp electroencephalogram, which comprises four main hollow flexible rules a, b, c and d, four side hollow flexible rules alpha, beta and theta, a top buckle (i) and eight sliding buckles (i-nini); the top buckle fixes the starting ends of the four main hollow flexible rulers to be a point o;

the main hollow flexible rule and the side hollow flexible rule are both provided with hollow rails extending in the extension direction of the flexible rule for the sliding buckle to slide, as shown in fig. 7, wherein the flexible rule can be the main hollow flexible rule or the side hollow flexible rule, no matter the main hollow flexible rule or the side hollow flexible rule, the structures of the main hollow flexible rule and the side hollow flexible rule are the same, the difference only exists in the measuring process, the two ends of the flexible rule are closed, the sliding buckle is prevented from sliding out of the flexible rule relatively, and length scales are marked on two sides or any single side of the hollow flexible rule in the extension direction of the flexible rule;

each side hollow flexible rule is respectively connected with the hollow tracks of two adjacent main hollow flexible rules through two sliding buckles arranged in the hollow track, so that each sliding buckle simultaneously slides in the hollow tracks of one side hollow flexible rule and the corresponding main hollow flexible rule. For example, as shown in fig. 3, the side hollow flexible rule α is connected to the main hollow flexible rule a through a sliding buckle disposed in a hollow rail thereof, the sliding buckle is also disposed in the hollow rail of the main hollow flexible rule a and is slidable therein, and at the same time, the side hollow flexible rule α is connected to the main hollow flexible rule c through a sliding buckle disposed in the hollow rail thereof, and the sliding buckle is also disposed in the hollow rail of the main hollow flexible rule c and is slidable therein. Based on the above description of the side hollow flexible rule α, the connection relationship between the other side hollow flexible rules β, θ and the corresponding main hollow flexible rules b, c, d through the corresponding sliding fasteners can be clearly known from fig. 3, and will not be described herein again.

Particularly, as shown in fig. 8, a slide fastener is combined with a hollow tape, the slide fastener is composed of a slide body B and a top cap a, and the diameter of the slide body is d (larger than the width m of a hollow track C of the hollow tape), so that, when the slide fastener is disposed in the hollow track, both sides of the hollow track are tilted up or down (because d > m) due to the slide body disposed therein, and such deformation will increase the pressure between both sides of the hollow track and the slide body of the slide fastener, thereby increasing the frictional force therebetween.

Wherein each side hollow flexible rule has sufficient length for the sliding buckle to slide relative to the flexible rule, so that any point in the area enclosed by the circumference of the outer solid line shown in fig. 2 (preferably the area enclosed by the inner dotted line) can be measured by a corresponding one of the four side hollow flexible rules.

Each side hollow flexible rule is respectively connected with the hollow tracks of two adjacent main hollow flexible rules through two sliding buckles arranged in the hollow tracks, so that each sliding buckle is simultaneously connected with the two adjacent side hollow flexible rules and one main hollow flexible rule positioned between the two side hollow flexible rules. For example, as shown in fig. 4, the side hollow flexible rule α is connected to the main hollow flexible rules a and c through the slide fasteners disposed in the hollow rails thereof, the side hollow flexible rule β is connected to the main hollow flexible rules c and b through the slide fasteners disposed in the hollow rails thereof, the side hollow flexible rule is connected to the main hollow flexible rules a and d through the slide fasteners disposed in the hollow rails thereof, and the side hollow flexible rule θ is connected to the main hollow flexible rules b and d through the slide fasteners disposed in the hollow rails thereof; the slide fastener is simultaneously positioned in the hollow tracks of the side hollow flexible rule alpha and the main hollow flexible rule a to connect the side hollow flexible rule alpha and the main hollow flexible rule a together, the slide fastener is simultaneously positioned in the hollow tracks of the side hollow flexible rules alpha, beta and the main hollow flexible rule c to connect the side hollow flexible rules alpha, beta and the main hollow flexible rule c together, the slide fastener is simultaneously positioned in the hollow tracks of the side hollow flexible rules theta, beta and the main hollow flexible rule b to connect the side hollow flexible rules theta, beta and the main hollow flexible rule b together, and the slide fastener is simultaneously positioned in the hollow tracks of the side hollow flexible rule theta and the main hollow flexible rule d to connect the side hollow flexible rule theta and the main hollow flexible rule d together.
