Description

  The present invention relates to a drape.

  When performing surgery (eg, catheterization) on a patient, the patient's body is usually covered with a drape. By covering the patient's body with a drape (hereinafter, this state is referred to as “use state”), for example, the body fluid (blood) that has flowed out of the body due to surgery or the dispersion of liquids such as physiological saline can be prevented. A clean area of the operative field can be ensured by preventing a decrease in body temperature or by exposing a part of the patient's body that has not been disinfected.

  This drape is composed of a sheet-like drape main body and a plurality of openings provided in the drape main body. In use, the patient's surgical field is exposed from each opening, and surgery (for example, introduction of a catheter) can be performed on the surgical field.

  However, with such a drape, the size of each opening may not be appropriate, that is, it may be too large or too small (problem) depending on the patient's physique and the target site for surgery. .

  In addition, after the operation, when checking whether internal bleeding or the like has occurred around the surgical site (surgical field) or performing operations such as hemostasis of the surgical site, the opening is small and the operation may be difficult.

  In view of the former problem, the drape described in Patent Document 1 is known. This drape includes a sheet-shaped drape main body (base fabric), an opening (opening window (hole)) provided in the drape main body, and a lid (opening window cover) that is detachably attached to the opening. It consists of In the drape of patent document 1, the magnitude | size of the said opening part can be changed by changing the mounting position of the cover body with respect to an opening part.

  However, in the drape having such a configuration, as described above, the lid body is peeled off and pasted (attached) at different positions to change the size of the opening, so that the operation of the lid body is performed. That is, there is a problem that the peeling and mounting work of the lid is troublesome.

  Moreover, since the size of the opening itself cannot be expanded with the drape having such a configuration, it cannot sufficiently cope with the confirmation work or hemostasis work after the operation.

  In addition, the thickness of the portion where the lid is attached increases. For this reason, there was also a problem that it became difficult to handle the drape.

  In addition, there is a problem that the lid is lost during the operation, or the lid is peeled off and falls to the floor of the operating room.

  Further, since the lid is formed separately from the drape body, the number of parts constituting the drape increases. For this reason, there also existed a problem that a drape became high in cost.

Examples of the constituent material of the nonwoven fabric include synthetic resins such as polyurethane, polyvinyl alcohol, polypropylene, polyether polyamide, polyethylene terephthalate, and polybutylene terephthalate, and natural fibers such as wood pulp. What mixed 2 or more types can be used.

  Moreover, it is preferable that the surface of the drape body 2 is subjected to a hydrophilic treatment. As a result, it is possible to absorb body fluid (for example, blood) or physiological saline that has flowed out of the patient P. For example, this liquid prevents the hand from slipping and preventing surgery from being performed. Or the liquid can be prevented from being scattered on the floor surface of the operating room and contaminating the floor surface.

  Moreover, although the magnitude | size of the drape main body 2 is based also on a patient's physique and the magnitude | size of an operating room, for example, it is preferable that length is 2500-3500 mm, and it is more preferable that it is 2800-3200 mm. Further, the width is preferably 1500 to 2500 mm, and more preferably 1800 to 2200 mm.
