Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surgical partition curtain device and a partition curtain used for partitioning a dirty area and a clean area.

[0002]

2. Description of the Related Art For example, at the time of heart surgery, a pump,
An extracorporeal circulation device including a reservoir, an artificial lung, and the like (external devices constituting the device) is connected to a patient via a plurality of tubes. Since the operative field side where the patient and the operator are present is a clean area, it is necessary to hygienically isolate from the unclean area where external devices are present. Therefore, a sterilized partition curtain (sanitary sheet) is used. The partition curtain is located between the operative field side and the external device side, and is arranged so as to cover the external device together with a part of the tube extending from the external device.

By the way, at the initial stage of using the extracorporeal circulation device, a liquid such as blood called priming is initially filled in order to remove the air inside the external devices and the tube, but the amount of priming is made as small as possible. for,
It would be desirable to keep the tube as short as possible, i.e. to place the external equipment as close to the patient as possible. The provision of the external devices near the patient in this manner increases the chances of the operator touching the external devices, and the importance of the partition curtain increases.

[0004]

By the way, since the conventional partition curtain simply covers the external equipment and the like from above together with a part of the tube extending therefrom, the partition curtain should be avoided when disposing the tube. It was necessary, and this necessitated a fairly long tube. More specifically, the tube is usually arranged so as to connect the patient and the external device by bypassing the peripheral edge portion, particularly the lower edge portion, of the partition curtain that covers the external device. The tube is arranged so as to extend downward from the external equipment and then pass directly below the lower edge of the partition curtain, and then extend upward again to the height of the patient. Of course, if the lower edge position of the partition curtain is made higher, it is possible to shorten the tube installation length. However, in this case, since the partition curtain does not exist at the lower position, the lower position Contamination of the surgeon becomes a problem. Such a problem similarly occurs when the tube is arranged not only at the lower edge portion of the partition curtain but also at other edge portions such as the upper edge portion.

The present invention has been made in consideration of the above circumstances, and an object thereof is to ensure that the operative field side and the external device side are hygienic in a wide range while shortening the tube. An object of the present invention is to provide a partition curtain device and partition curtain for surgical operation that can be shut off.

[0006]

In order to achieve the above object, the present invention basically forms an opening through which a tube is inserted at a position apart from the peripheral edge of the partition curtain. There is. This allows the tube to
Without circumventing the peripheral edge of the partition curtain, especially the lower edge,
The partition curtain can be arranged so as to penetrate therethrough, and the installation length can be shortened.

In addition to forming an opening for inserting a tube in the partition curtain, in the present invention, the first solving method is as follows. That is, as described in claim 1 in the claims, a partition curtain formed with an opening through which a tube is inserted at a position apart from the peripheral edge, and a peripheral curtain of the opening of the partition curtain. It is provided with a formed locking portion and an engaging portion formed on an outer peripheral portion of the tube inserted through the opening and engaged with the locking portion.

With the partition curtain folded in two, cover the external equipment and disinfect the operative field side, which will be the clean area. After the disinfection, by opening the double-folded partition curtain, the operative field side has two surfaces that were folded in two and faced each other at the time of disinfection, that is, two surfaces that were not exposed to the outside and remained clean. It will appear.

Since the opening is at a position offset from the folding line of the two-fold, when the operative field side is disinfected in the folded state as described above, the half of the partition curtain having the opening is halved. By covering this part from the operative field side with the remaining half of the partition curtain on the side that does not have an opening, it is preferable to prevent accidental contact with the opening or its vicinity. Become. Further, even if the opening is preliminarily equipped with a mounting plate for holding the tube or the like, the partition curtain can be easily folded into two without being obstructed by these.

In addition to forming an opening for inserting a tube in the partition curtain, in the present invention, the fifth solving method is as follows. That is, as described in claim 9 in the claims, there is provided a surgical partition curtain in which an opening for inserting a tube is formed at a position distant from a peripheral portion, wherein the partition curtain has the tube.
