Description

  The present invention relates to a sterilization drape used for sterilizing the outside of a surgical instrument or the like in an operating room, for example, in a surgical operation such as neurosurgery, ophthalmology, or orthopedic surgery.

2. Description of the Related Art Conventionally, in an operating room, a surgical operation is performed by placing a sheet-like sterilized drape over the entire surgical instrument such as a surgical microscope, so that the outer side of the surgical instrument is kept in a clean and sterile state. . Such a sterilized drape is sterilized by an operator who is in a sterilized state so as to form a desired sterilization space suitable for the operation without being contaminated on the outside while being attached to a surgical instrument. A person holds in his hand and covers the entire outside of the surgical instrument (see, for example, Patent Document 1).
Japanese Patent No. 2988981

  However, in the above-described sterilization drape, if the operator who covers the surgical instrument is not a clean person who is in a sterilized state, the outer side of the operator is contaminated and it is difficult to realize a desired sterilization space. Thus, for example, since it is limited to sterilizers such as an operator who performs surgery, the deposition work is a heavy burden.

  In addition, in the above-mentioned sterilization drape, since there is a risk that the sterilizer may touch surrounding parts that are not in a sterilized state during the adherence operation on the surgical equipment, the operation is very troublesome and takes a relatively long time. Has the problem of spending.

  In addition, if the outside of the drape is contaminated, the sterilizer's deposition operation is temporarily stopped, and the non-sterile person removes the drape that has been partially adhered, and then again. This has the problem of delaying the operation because the sterilizer must apply a new uncontaminated drape.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a sterilized drape that can easily and easily realize the formation of a sterilized surface without being restricted by an operator. To do.

  In this invention, a transparent sheet material having sterilized flexibility is stacked and formed into a two-layer bag shape in which the layers are sealed in a hollow shape, and a detachable separation portion is provided on the outer layer side. A sterile drape was constructed with a sterile sheet.

  According to the above configuration, the sterilization sheet is sterilized by cutting off the cut-off portion in a state where the surgical sheet is covered from the bag-like opening side and turning the outer layer side of the transparent sheet material upside down from the cut-off portion. The two-layered inner surface is covered with an outer surface. Therefore, it is possible to easily and easily sterilize the surface as an outer surface without being restricted by the operator's sterilization.

  The present invention also includes a first and second transparent sheet layer formed in a bag shape with a sterilized transparent sheet material having flexibility, and a first transparent sheet layer on the outer layer side. The sterilization drape was configured with a sterilization sheet provided with a detachable separation part.

  According to the above-described configuration, the sterilization sheet is separated from the separation device in a state where the sterilization sheet is placed on the surgical instrument from the bag-like opening side of the first and second transparent sheet layers arranged in the interior, and the first layer on the outer layer side. By disengaging one transparent sheet layer from the second transparent sheet layer, the inner surface side of the second transparent sheet layer subjected to sterilization facing the first transparent sheet layer is exposed as the outer surface. . Therefore, it is possible to easily and easily sterilize the surface as an outer surface without being restricted by the operator's sterilization.

  As described above, according to the present invention, it is possible to provide a sterilized drape that can easily and easily realize the formation of a sterilized surface without being restricted by an operator.
