Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cover for covering a surgical instrument table on which various instruments and instruments such as scalpels and forceps used for surgery are placed.

[0002]

2. Description of the Related Art Generally, a surgical instrument table has a plurality of metal bats (metal square plates) placed side by side on a frame-shaped upper part, and a cover (oif Called) and various instruments and instruments for operation are placed on the bat from above the cover. The cover is supplied as a product form in which a flexible sheet made of various materials such as non-woven fabric, woven fabric, paper, and synthetic resin is folded and aseptically packaged, and is used as a disposable product to prevent bacterial infection and the like. Discarded after each use.

However, such a surgical instrument base cover is unfolded from the folded state at the time of supply when it is put on the instrument stand in use, but it cannot be handled with bare hands to keep the surgical environment sterile and is light. In addition, since it is slippery with respect to the bat, there is a problem in that it is difficult to put the bat on an appropriate position. Therefore, as a cover for coping with this difficulty, a double-sided adhesive sheet is attached near the center of the cover body, and a film having an opening portion and release paper are sequentially attached on this adhesive sheet, and in use, It has been proposed that the release paper be peeled off and the adhesive surface exposed from the opening of the film be fixed to the bat surface or the like on the instrument table so that it can be deployed on the instrument table without displacement. (Jpn. Pat. Appln. KOKAI HEI 3-19848).

[0004]

However, in the case of the surgical instrument base cover according to the above-mentioned proposal, it is necessary to peel off the release paper adhered to the adhesive surface of the double-sided adhesive sheet at the time of use. However, it is difficult to operate because it is difficult to operate because it is necessary to pinch the edge of the release paper with forceps etc., and the peeled release paper becomes garbage that should be disliked in the surgical environment. There was a problem.

In view of the above-mentioned circumstances, the present invention can easily expose the adhesive surface without the need for the cumbersome and difficult operation for peeling off the release paper as in the prior art, and the position of the adhesive surface can be utilized. An object of the present invention is to provide a surgical instrument table cover that can be easily deployed and covered on the instrument table in a state of not being displaced, and that does not generate dust such as the peeled release paper.

[0006]

In order to achieve the above object, a surgical instrument table cover according to claim 1 of the present invention comprises:
A double-sided pressure-sensitive adhesive sheet piece is attached to one side of a cover body made of a flexible sheet at a substantially central position of the cover body, and a single-sided pressure-sensitive adhesive sheet piece is placed at a lateral position apart from the double-sided pressure-sensitive adhesive sheet piece. Is adhered, and the cover body is folded in such a manner that the double-sided adhesive sheet piece and the single-sided adhesive sheet piece are joined together.

In the surgical instrument base cover having the above structure, the non-adhesive surface of the single-sided adhesive sheet piece is bonded to the adhesive surface of the double-sided adhesive sheet piece in the folded state at the time of supply.
At the time of use, by simply opening the cover body in the folded form so as to expose the opposite surfaces to which both sheet pieces are adhered, the double-sided adhesive sheet piece and the single-sided adhesive sheet piece that were joined spontaneously separate, and double-sided adhesive The adhesive surface of the sheet piece is exposed. Therefore, place the cover that has been opened in such a way that both opposing surfaces are exposed and that is otherwise undeployed on the instrument table so that the exposed adhesive surface adheres to the bat surface, etc. on the instrument table. ,
Therefore, it can be easily deployed without causing displacement and can be put on the entire upper part of the instrument table. Since the single-sided pressure-sensitive adhesive sheet piece separated from the double-sided pressure-sensitive adhesive sheet piece by the above-mentioned opening operation is in a state of being attached to the cover body, dust is not generated unlike the cover using the conventional release paper.

According to a second aspect of the present invention, in the surgical instrument base cover of the first aspect, an opening smaller than the adhesive surface of the double-sided adhesive sheet piece is provided on the double-sided adhesive sheet piece attached to the cover body. Since the perforated sheet piece is attached to the cover body, the adhesive area between the double-sided adhesive sheet piece and the single-sided adhesive sheet piece is smaller than the adhesive area of both sheet pieces to the cover body. Therefore, even if a normal double-sided adhesive sheet piece having no difference in adhesive strength on both sides is used, one sheet piece is peeled from the cover body and transferred to the other sheet piece when the two sheet pieces are opened. Even if you do not wear them, and you use the same size as both sheet pieces, the adhesive surface of the double-sided adhesive sheet piece sticks out from the surface of the facing single-sided adhesive sheet piece with the cover folded. Can be prevented from being attached to the cover body.

According to the third aspect of the present invention, the first or second aspect is provided.
In the surgical instrument table cover of, the bar body is a strip-shaped central portion where the double-sided adhesive sheet piece and the single-sided adhesive sheet piece are lined up, and the strip-shaped side portions on both sides are the sheet piece non-sticking surface side of the central portion. In addition to being folded and folded, the folded belt-like material is folded in three so that the double-sided adhesive sheet piece and the single-sided adhesive sheet piece are joined together. Therefore, at the time of use, both sheet pieces can be separated and the adhesive surface can be exposed by an extremely simple operation of opening one fold portion in the last three-fold, and the adhesive surface can be used to mount on the machine table. There is no room for making an error in the procedure for expanding the cover with the cover attached, and the unfolding operation becomes easy.

According to a fourth aspect of the present invention, in the surgical instrument cover of the third aspect, the strip-shaped side portions on both sides are zigzag-folded and do not overlap each other in a narrow state, and the strip-shaped central portion is formed. Since it is folded on the sheet piece non-sticking surface side of the above, the adhesive surface exposed by opening the one folding part of the above-mentioned three-fold is fixed to the bat surface etc. on the instrument table and left. After unfolding the folded portions at some places and releasing the three-fold, when the strip-shaped side portions on both sides are expanded, these strip-shaped side portions do not interfere with each other.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION A surgical instrument base cover according to an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows the cover in a developed state, and FIG. 2 shows the cover in a folded state with one folding portion opened.

As shown in FIG. 1, this surgical instrument base cover (1) is a rectangular (illustrated square) cover body (1) made of a flexible sheet of non-woven fabric, woven fabric, paper, synthetic resin or the like.
0) is provided with a circular adhesive surface (20) at a substantially central position on one side thereof, and a single-sided adhesive sheet piece (3) is attached at a lateral position apart from the adhesive surface (20). ing.

As for the adhesive surface (20), as shown in FIGS. 3 and 4, the double-sided adhesive sheet piece (2) is attached to the cover body (10) with the adhesive layer (2a), and the adhesive layer (2a) is placed thereon. By sticking a perforated sheet piece (4) made of a synthetic resin film or a release paper having a circular opening (4a), the adhesive layer of the double-sided adhesive sheet piece (2) from the opening (4a). The surface of (2b) is exposed. The double-sided pressure-sensitive adhesive sheet piece (2), the perforated sheet piece (4), and the single-sided pressure-sensitive adhesive sheet piece (3) are set to have substantially the same square size. As the double-sided pressure-sensitive adhesive sheet piece (2), an ordinary commercially available product having no difference in the adhesive strength between the pressure-sensitive adhesive layers (2a) and (2b) on both sides is used.

Thus, the surgical instrument base cover (1) is supplied in the form of a product that is folded and aseptically packaged. This fold is defined by the fold lines y1 to y3 in the vertical direction shown by the phantom line in FIG. It is performed based on the folding lines x1 and x2 of the direction.

That is, the cover body (10) has a strip-shaped central portion where the adhesive surface (20) and the single-sided adhesive sheet piece (3) are lined up by a pair of vertical folding lines y1 and y1 located on the center side in the figure. (A) and strip side parts on both sides thereof (B)
(B), fold lines y1 and y3 into mountain folds, fold line y
