The pipe coupling hole (125) is a space for joining one end of the pipe (130). As previously mentioned, the tube (130) may be integrally formed with the suction head (120) of the connector (100) or may be configured to be coupled/separated on the suction head (120).

As shown in Fig. 3, a release film (141, 142) is provided on the lower surface of the head adhesive film (110). The release film (141, 142) is used to protect the adhesive layer applied under the head adhesive film (110).

The release film (141, 142) may include a first release film (141) and a second release film (142).

The second release film (142) may be partially attached to the lower surface of the head adhesive film (110). As shown in FIG. 3, a portion of the second release film (142) is not attached to the head adhesive film ( 110) The lower surface is provided in a state of being folded outward to overlap with another portion.

The first release film (141) may be attached to the remaining portion of the head adhesive film (110) not covered by the second release film (142), as shown in Fig. 3, a part of the first release film (141) It is not attached to the lower surface of the head adhesive film (110) but is provided in a state of covering the second release film (142).

Therefore, before attaching the connector (100) to the upper surface of the drape (300), the user grasps a portion of the first release film (141) that is not attached to the lower surface of the head adhesive film (110). The first release film (141) is removed. After the first release film (141) is removed, the second release film (142) is exposed, and the user can grasp the second release film (142) that is not attached to the lower surface of the head adhesive film (110). The second release film (142) is partially removed.

As the first release film (141) and the second release film (142) are removed, an adhesive layer formed on the lower surface of the head adhesive film (110) is exposed, and the connector (100) can be bonded and fixed to the vertical curtain. (300) Upper surface.

Conventionally, after the suction head is placed on the vertical curtain, the suction head is fixed to the vertical curtain, and the suction head is covered by another vertical curtain to be fixed to the vertical curtain. However, the connector (100) of the present embodiment is pre-bonded with the head adhesive film (110). The lower surface of the flange portion (121) of the suction head (120) is configured to be removed, so that the release film (141, 142) can be removed and the suction head (120) can be directly attached and fixed to the drape.

Fig. 4 is a cross-sectional view showing a state in which a connector of one embodiment of the present invention is attached to a drape.

As shown in Fig. 4, the connector (100) is bonded to the upper surface of the drape (300) in a state where the release film (141, 142) is removed.

As shown in Fig. 4, the thickness (t2) of the head adhesive film (110) of the connector (100) of one embodiment of the present invention is formed thicker than the thickness (t1) of the drape (300). The head adhesive film (110) is formed thicker than the drape (300), so that when the head adhesive film (110) and the drape (300) are formed of the same/similar material, the head adhesive film (110) has an elastic force greater than that of the drape (300). . Therefore, when the same tensile force acts on the head bonding film (110) and the drape (300), the amount of deformation of the head bonding film (110) is smaller than that of the vertical curtain (300).

In the case where the elastic force of the vertical curtain and the head adhesive film is similar, the vertical adhesion of the vertical curtain and the head bonding film by the stretching force acting on the vertical curtain and the head bonding film simultaneously causes a gap between the vertical curtain and the head bonding film, thereby decompressing. The possibility of leakage is high.

In contrast, in the present embodiment, since the head adhesive film (110) has an elastic force larger than that of the vertical curtain (300), even when the connector (100) is attached to the drape (300), even if it acts on the connector ( 100) External force, tensile force acts on the drape (300) and the head adhesive film (110), and the portion of the drape (300) that is not in contact with the head adhesive film (110) absorbs the tensile force and deforms first. Therefore, even if a force other than the tensile force is applied to the drape (300) and the head bonding film (110), the bonding state between the head bonding film (110) and the drape (300) can be maintained, and leakage of the decompression can be prevented.

Fig. 5 is a cross-sectional view showing a state in which a connector according to another embodiment of the present invention is attached to a drape. For the convenience of explanation, the same components as those of the foregoing embodiments are denoted by the same elements, and the same portions as those of the foregoing embodiments are omitted.

As shown in Fig. 5, as another embodiment, the head adhesive film (110') may be formed by laminating a plurality of adhesive films (110a, 110b). In the fifth drawing, an example in which two adhesive films (110a, 110b) are laminated is illustrated, but three or more adhesive films may be laminated.

As shown in Fig. 5, a plurality of adhesive films (110a, 110b) may be laminated to form the elastic force of the head adhesive film (110') to be larger than the elastic force of the vertical curtain (300). Each of the adhesive films (110a, 110b) may be formed of the same material and thickness as the drape (300).

The head adhesive film (110') of this embodiment also has an elastic force higher than that of the vertical curtain (300), so that the same or similar effects as those of the foregoing embodiment can be achieved.

As another embodiment, the head adhesive film may be formed of a material having a higher elastic force than the vertical curtain (300). At this time, even if the head-adhesive film is formed to have substantially the same thickness as the drape (300), it has an elastic force higher than that of the drape (300), so that the same or similar effects as those of the foregoing embodiment can be achieved.

It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit of the invention. Therefore, the above described embodiments are to be considered in all respects as illustrative and not limiting.
