As shown in fig. 3 and 4, the sliding guiding spherical surface 121 is provided with a plug groove 123, and the anti-disengaging structure 220 is provided with a plug 221 matching with the plug groove 123.
The following describes a method for using the disposable noninvasive electroencephalograph sensor 10 (see fig. 6 and 7 together):
the operator holds one hand on the first fixing ring 110 of the coupling male 100 and the other hand on the movable sleeve 510 of the sub-coupling block 500;
aligning the male connection head 100 with the female connection head 200, and applying a force by two hands of an operator in opposite directions, so that the male connection head 100 and the female connection head 200 start to approach each other; even if the mating is not accurate, since the hemisphere structure 120 has the sliding guiding sphere 121, one end of the elastic latch 520 slides along the sliding guiding sphere 121, so as to realize the stable mating of the socket 123 and the plug 221;
it should be particularly noted that, in an original state before plugging, the elastic claw buckle 520 is in an expanded state and partially exposed outside the limiting chamber 530, the expanded elastic claw buckle 520 is supported by the end surface of the movable sleeve 510, and a friction force exists between the elastic claw buckle 520 and the end surface of the movable sleeve 510;
firstly, the plug 221 on the anti-disengaging structure 220 is plugged into the plugging slot 123 of the sliding guiding sphere 121 (the movable sleeve 510 drives the elastic claw buckle 520 through friction force, and the elastic claw buckle 520 drives the plug 221 through the anti-disengaging structure 220), and in the process that the plug 221 is plugged into the plugging slot 123, one end of the elastic claw buckle 520 presses and pushes the pressing block 410 to slide a small distance along the sliding guiding rod 130 (due to the friction force existing between the elastic claw buckle 520 and the end surface of the movable sleeve 510, the friction force is enough to overcome the elastic force of the elastic member 420 to the pressing block 410, the elastic member 420 starts to contract, and the pressing block 410 also slides along the sliding guiding rod 130);
after the pressing block 410 slides a short distance along the sliding guide rod 130, a gap is generated between the pressing block 410 and the clamping end surface 122 of the hemispherical structure 120, and at this time, the plug connector 221 and the plug groove 123 are already plugged in place;
when the plug 221 and the plug groove 123 are plugged in place, the anti-falling structure 220 on the female connection head 200 can block the elastic claw catch 520, so as to prevent the elastic claw catch 520 from moving forward;
continuously applying an external force to the movable sleeve 510, wherein the external force overcomes the friction between the elastic latch 520 and the end surface of the movable sleeve 510, so that the movable sleeve 510 and the elastic latch 520 move relatively;
during the relative movement of the movable sleeve 510 and the elastic latch 520, the movable sleeve 510 presses the elastic latch 520, so that the entire elastic latch 520 begins to contract inward and enter the limiting chamber 530;
because the pressing block 410 and the holding end surface 122 of the hemispherical structure 120 form a gap, during the inward contraction process of the elastic claw catch 520, the wedge block 521 on the elastic claw catch 520 is engaged with the one-way tooth slot 411 through the gap, and under the action of the one-way tooth slot 411, the wedge block 521 can only move along one direction but can not move in the opposite direction, so that the elastic claw catch 520 is more tightened;
in the process that the elastic claw buckles 520 start to contract inwards, the elastic claw buckles 520 also enter the limiting chamber 530 at the same time, and as the cavity wall of the limiting chamber 530 is provided with the convex ring 531, the convex ring 531 can further extrude the elastic claw buckles 520, so that the wedge blocks 521 continuously move along the one-way tooth grooves 411 in one direction, and further the elastic claw buckles 520 are further tightened;
the operators stop applying force in opposite directions, and the connecting male head 100 and the connecting female head 200 are tightly connected together under the action of the auxiliary connecting piece 300 to realize stable connection;
in addition, the edge of the pressing block 410 is provided with a waterproof ring 412, and the waterproof ring 412 wraps the gap between the pressing block 410 and the movable sleeve 510, so that the sweat of the patient can be effectively prevented from entering the insertion groove 123 and the insertion connector 221, and the signal transmission is prevented from being interfered.
As can be seen from the above, the male connector 100 and the female connector 200 are tightly connected together under the action of the auxiliary connector 300, the hemispherical structure 120, the anti-separation structure 220, and the elastic claw 520 are stably held together, and if a reverse force is simply applied to the male connector 100 and the female connector 200, the plug-in groove 123 and the plug-in connector 221 cannot be separated.
From the above, if the pressing block 410 is merely shifted, although the one-way tooth socket 411 on the pressing block 410 is separated from the wedge-shaped block 521 on the elastic claw buckle 520, the elastic claw buckle 520 is not expanded under the limitation of the convex ring 531, the hemispherical structure 120, the anti-dropping structure 220 and the elastic claw buckle 520 are still firmly held together, and the inserting groove 123 and the inserting connector 221 are not separated;
as can be seen from the above, if the movable sleeve 510 is merely shifted, although the collar 531 on the movable sleeve 510 does not press the elastic claw catch 520, the wedge block 521 is clamped on the one-way tooth slot 411, the elastic claw catch 520 will not expand, the hemispherical structure 120, the anti-falling structure 220, and the elastic claw catch 520 will also be firmly clasped together, and the insertion groove 123 and the insertion connection plug 221 will not be separated.
Therefore, if the inserting groove 123 and the inserting head 221 are to be separated, an operator holds the pressing block 410 by one hand and holds the movable sleeve 510 by the other hand, and then applies a force in the opposite direction, so that the one-way tooth slot 411 and the wedge block 521 are separated, the elastic latch 520 is no longer pressed by the convex ring 531, and then the elastic latch 520 expands outward to be unlocked, the hemispherical structure 120 and the anti-disengaging structure 220 are no longer restrained by the elastic latch 520, and the inserting groove 123 and the inserting head 221 can be separated smoothly.
As can be seen from the above description, the connection between the male connector 100 and the female connector 200 can be quickly achieved by the auxiliary connector 300, and an operator holds the male connector 100 with one hand and the movable sleeve 510 of the secondary connection module 500 with the other hand, and applies force to the two hands to complete the connection, so that the operation is very convenient.
As can be seen from the above description, the male connection head 100 and the female connection head 200 can be quickly separated, and an operator can hold the pressing block 410 with one hand and the movable sleeve 510 with the other hand, and then separate the two hands by applying force in opposite directions, so that the operation is very convenient. However, it should be noted that if the auxiliary connector 300 is not unlocked in the correct manner, the connection male connector 100 and the connection female connector 200 are not separated, and the connection is easy and stable, and the unlocking is not easy.
Here, it is also to be particularly noted that, in consideration of the elastic force of the elastic claw 520, the elastic claw 520 is preferably made of a metal material, so that a long-lasting and good elastic force is obtained; the movable sleeve 510, the second fixing ring 210, the anti-slip structure 220, and the sliding guide column 230 are preferably made of plastic, and are easily manufactured by injection molding. As can be seen from the above description, the elastic claw 520 and the anti-separation structure 220 are made of different materials, so that the elastic claw 520 and the anti-separation structure 220 can only be designed in a split manner.
The disposable noninvasive electroencephalogram sensor 10 has the characteristic of easy plugging and unplugging by arranging the auxiliary connecting piece 300, can be plugged and unplugged quickly, has good stability after plugging, can be unlocked only by medical staff who need to know the structure of a product to a certain extent when unplugged, and has higher reliability.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
