Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
At present, a clinically used device for fixing the electrode slice is an elastic mesh cap, and the device is worn on the head to cover the skin of the head, and then the electrode slice is tightly pressed on the head of a patient by utilizing the elasticity of the device to play a role in fixing.
However, in practical use, this method has a problem that the fixed electrode sheet is not firm. The reason is that:
1. some patients, especially male patients, typically shave their heads during electroencephalogram measurements, and then the electrode pads are attached to the scalp by adhesive. However, without the protection of hair, the direct contact of the scalp with the external environment easily causes the head to overflow the grease, thereby weakening the viscosity of the viscose and reducing the adhesion firmness of the electrode plate;
2. after the electrode plate is attached to the scalp of a patient, most of the wire harness connected with the electrode plate extends out of the position of the hindbrain spoon of the patient to be connected with external equipment, and the small part of the wire harness is positioned on the side edge of the head of the patient. And electroencephalogram detection is long, few hours and many days, and during the period, a patient needs normal life, such as sitting and lying, and a harness patient at the rear or at the side cannot see the device, so that the condition that the electrode plate is displaced due to the fact that the patient moves and pulls the harness is easily caused.
The existing mesh cap is made of elastic materials, but the elastic performance of the existing mesh cap is reduced after long-term use, so that the pressing force on the electrode plate is reduced, and the existing mesh cap is not provided with a part for restraining the wire harness of the electrode plate, so that the tension mesh cap caused by the wire harness to the electrode plate is difficult to eliminate.
Therefore, as shown in fig. 1 to 2, the present utility model provides an electroencephalogram electrode sheet fixing device. Comprises a mesh fixing cap 1, wherein a net cap fixing component and a wire harness fixing component 2 are arranged on the mesh fixing cap 1.
The net cap fixing assembly comprises an annular elastic part 3 and a longitudinal tensioning part 4, the annular elastic part 3 is circumferentially arranged on the lower edge of the net cap 1 and used for fixing the net cap 1 on the head, the longitudinal tensioning part 4 is arranged on two sides of the net cap 1, and the longitudinal tensioning part extends downwards and is used for downwards pulling the net cap 1 to be attached to the head.
The wire harness fixing assembly 2 is arranged on the mesh fixing cap 1, a plurality of buckles 5 are arranged on the wire harness fixing assembly 2, and the buckles 5 are connected with the wire harness and used for limiting the wire harness.
The longitudinal tightening parts on two sides are connected with the annular elastic part 3 at one end and extend downwards at the other end and are connected at the lower jaw of the patient, and the longitudinal elastic belts can stretch and retract to adapt to patients with different facial forms.
The device is provided with a longitudinal tightening and circumferential surrounding part on the mesh fixing cap 1, and the top of the mesh fixing cap 1 can be attached to the scalp on the top of the head of a patient through the downward extension of the longitudinal tightening part 4. In particular, the longitudinal tensioning portion 4 can be extended to the mandibular position of the patient and connected, thereby being fixed to the head. The longitudinal stretching portion can control the fitting degree of the mesh fixing cap 1 on the scalp of the head by controlling the length of the downward tension, so that such an arrangement can ensure the fixing performance of the mesh fixing cap 1.
Further, an annular elastic portion 3 is provided. The wire harness of the electrode sheet is generally long, and is not connected to an external device horizontally and laterally, but is connected to the external device after extending downward. Therefore, the annular elastic band can be used for binding the wire harness on the head of the patient by encircling the circumference of the head of the patient.
Finally, the wire harness is further fixed by the wire harness fixing assembly 2, so that the stability of the electrode plate adhesion is ensured.
As shown in fig. 1, the inner side of the annular elastic part 3 is connected with an avoiding dressing belt 6, a plurality of avoiding hole grooves 7 are formed in the avoiding dressing belt 6, and the avoiding dressing belt 6 is movably bonded with the inner side of the annular elastic part 3.
In practical application of a hospital, some patients who undergo head surgery can leave a binding band on a head wound, the binding band can enable the wound to bulge, such as sphenoid surgery, frontal bone surgery and the like, if the annular elastic part 3 is directly arranged on the wound, the wound is possibly pressed to be unfavorable for recovery, so that the avoiding dressing belt 6 is arranged on the inner side of the annular elastic part 3, the avoiding dressing belt 6 can be a soft rubber block or a flexible cloth fabric, a gap is needed on the elastic band in any way, the whole circle is not needed on the elastic band, the annular elastic band wound outside the elastic band is the whole circle, and the purpose of the gap is to avoid the wound.
The avoidance dressing belt 6 can be connected in the annular elastic belt through a magic tape, so that the notch position can be changed, and the device is more flexible to use.
The buckle 5 comprises a base 8 and clamping arms 9, the surface of the base 8 is inwards sunken to form a clamping groove 10, two clamping arms 9 are arranged in the clamping groove 10, the two clamping arms 9 are rotationally connected in the clamping groove 10 through torsion springs, the two clamping arms 9 are symmetrically arranged, one ends of the two clamping arms are mutually close to each other and are arranged in the clamping groove 10 in a V-shaped mode, and a large opening of the V-shaped mode faces the outside of the clamping groove 10.
The one end that two centre gripping arms 9 are close to each other is provided with arc parcel piece 11, and two arc parcel pieces 11 are close to each other and form the oval parcel piece that the minor diameter is less than the pencil diameter in order to centre gripping fixed pencil, and are provided with the abrasive grain on the face that two arc parcel pieces 11 are relative.
The buckle 5 is like the V-shaped, and the pencil gets into from the big mouth of V-shaped, utilizes the effect of torsional spring to automatic centre gripping fixed with centre gripping arm 9 to prevent the pencil and remove. The specific arrangement may be such that the V-shaped clamping arm 9 is arranged back and forth in the horizontal direction, i.e. the large opening of the V-shape is far away from the head towards the outside, the small opening of the V-shape is close to the head, and the cylindrical object formed by the two arc wrapping sheets 11 is arranged at the small end of the V-shape, which is arranged longitudinally, and the two openings are respectively directed upwards and downwards. Thus, the wire harness can be pushed into the arc-shaped wrapping sheet 11 from the large end and then clamped by the arc-shaped wrapping sheet 11. And since the holding arms 9 are V-shaped, the wire harness is easy to enter but not easy to exit, thereby restricting the escape of the wire harness.
The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application, the scope of which is defined by the claims. Various modifications and equivalent arrangements may be made to the present application by those skilled in the art, which modifications and equivalents are also considered to be within the scope of the present application.
