Description

The present invention relates to a drape manufacturing method .

  When performing surgery (eg, catheterization) on a patient, the patient's body is usually covered with a drape. Also, in the peritoneal dialysis method, particularly continuous ambulatory peritoneal dialysis (CAPD), the patient's abdomen is covered with drape. The drape used for this peritoneal dialysis is formed with a cut for inserting a catheter or the like.

  Such a drape is used as a surface where one surface faces a clean area. Moreover, in order to reduce the storage space of the drape, the drape is stored by being folded a plurality of times, and is spread during use (see, for example, Non-Patent Document 1).

  However, in the conventional folding method applied to the drape, when the drape is widened, the notch becomes an obstacle and it is difficult to spread it with one hand. For this reason, it is necessary to spread the drape with both hands, which is troublesome, and there is a drawback that the drape is unnecessarily brought into contact with the surface facing the clean area by grasping the drape with both hands.

It is a top view for demonstrating the procedure at the time of folding the drape shown in FIG. It is a top view which shows the state which expanded the drape in 3rd Embodiment of the manufacturing method of the drape of this invention. FIG. 7 is a plan view (including a partial perspective view) for explaining a procedure when the drape shown in FIG. 6 is folded.

Hereinafter, the drape manufacturing method of the present invention will be described in detail based on preferred embodiments shown in the accompanying drawings.
<First Embodiment>
1 is a plan view showing a drape in the first embodiment of the drape manufacturing method of the present invention, FIG. 2 is a plan view showing a state in which the drape shown in FIG. 1 is expanded, and FIG. 3 is a drape shown in FIG. It is a top view (a partial perspective view is included) for demonstrating the procedure at the time of folding up.

  In the following description, the upper side in FIGS. 1 to 3 is “upper”, the lower side is “lower”, the left side is “left”, and the right side is “right”. In addition, in FIGS. 1 to 3, the X axis and the Y axis that are perpendicular to each other and in which the cutting direction is the Y axis direction in a state where the drape is widened are illustrated. Further, in FIG. 2, the notch is exaggerated and shown by a thick line.

  The drape 1 shown in FIGS. 1 to 3 is flexible and has a sheet shape. As shown in FIG. 1, the drape 1 is folded a plurality of times and stored in the folded state. In addition, the drape 1 is used in, for example, peritoneal dialysis in the present embodiment.

  The drape 1 is used in an expanded state, that is, in an expanded state. Moreover, the drape 1 is used as a surface where one surface faces a clean area, and the other surface is used as a surface facing an unclean area. Hereinafter, the surface facing the clean area of drape 1 is also referred to as “clean surface”, and the surface facing the unclean area of drape 1 is also referred to as “unclean surface”. The state in which the drape 1 is folded is also simply referred to as “folded state”, and the state in which the drape 1 is unfolded is simply referred to as “open state”.

  The drape 1 is used over the patient such that the unclean surface is proximal to the patient, i.e., facing the patient, and the clean surface is distal to the patient.

  The shape of the drape 1 in the unfolded state is a quadrangle in plan view, and in the present embodiment is a square. Note that the shape of the drape 1 in the expanded state is not limited to a square, and may be, for example, a rectangle or the like in plan view.

  The shape of the drape 1 in the folded state is a quadrangle in a plan view, and in this embodiment, the drape 1 is a square. In addition, the shape of the drape 1 in the folded state is not limited to a square, and may be a rectangle or the like, for example, in a plan view, or may be a triangle or the like.

  The drape 1 is provided with a grip portion 3. The grip portion 3 is a portion that is gripped when the drape 1 in a folded state is spread. The grip part 3 is configured by a corner part of the drape 1, that is, a corner part including any one vertex of a square, in an unfolded state. In the present embodiment, the grip portion 3 has a triangular shape in plan view.

  Further, the drape 1 has a cut 2 formed therein. This notch 2 is used when, for example, a catheter connected to the patient is inserted into the notch 2 when the drape 1 is applied to the patient. Thereby, the drape 1 can be applied to the patient so that the catheter does not get in the way.

  The shape, size, position, and the like of the cut 2 are not particularly limited, but in the present embodiment, the cut 2 is linear. The notch 2 is formed from the center of one side of the drape 1 toward the center with the drape 1 being expanded. In this embodiment, the notch 2 is formed from the center of the side with the corners forming the grip portion 3 toward the center in a state where the drape 1 is expanded. Further, the notch 2 is formed up to the center of the drape 1.

  Since the notch 2 is formed on a side with a corner that forms the grip portion 3, the grip portion 3 is gripped and the folded drape 1 is expanded, and then the grip portion 3 is gripped. The drape 1 can be applied to the patient while the catheter connected to the patient is placed in the cut 2.

  In addition, since the notch 2 is formed up to the center of the drape 1, when the folded drape 1 is expanded, the notch 2 is less likely to get in the way, and the drape 1 can be easily and reliably expanded. it can. Further, the drape 1 can be folded easily and quickly as compared with the case where the notch 2 is formed so as to extend beyond the center of the drape 1.

  In addition, the cut 2 is preferably formed with 3 cm as a lower limit. Thereby, the said catheter can be reliably put in the notch 2. FIG.

  The cut 2 may be formed up to the center of the drape 1, but is preferably formed up to the center and more preferably before the center. Further, the notch 2 may be formed in a side having no corner portion forming the grip portion 3. Moreover, as the cut | notch 2, notches, such as V shape and I shape, may be sufficient, for example.

  The constituent material of the drape 1 is not particularly limited, but it is preferable to use a flexible material such as a nonwoven fabric. Examples of the constituent material of this nonwoven fabric include aramid fiber, glass fiber, cellulose fiber, nylon fiber, vinylon fiber, polyester fiber, polyolefin fiber, and rayon fiber, and one or more of these are mixed. Can be used.

  Further, it is preferable that one surface of the drape 1, that is, the clean surface 11 is subjected to a hydrophilic treatment. As a result, liquids such as dialysate, physiological saline, and disinfectant can be absorbed. For example, the liquid can prevent the hand from slipping and difficult to perform the operation, or the liquid can be removed from the floor surface. It is possible to prevent the floor surface from being scattered and contaminated.

  Moreover, the drape 1 has the waterproof layer 7 on the surface opposite to the clean surface 11, that is, the unclean surface side (see FIG. 3E). The surface of the waterproof layer 7 is unclean. Thereby, it is possible to prevent liquids such as dialysate, physiological saline, and disinfectant from permeating the drape 1, and thus, for example, prevent this liquid from adhering to the patient's clothes and the like. can do. The constituent material of the waterproof layer 7 is not particularly limited as long as it has a waterproof function, and examples thereof include synthetic resins such as polyethylene and polyethylene terephthalate.

  Although the dimension in the state which such a drape 1 extended is not specifically limited, It is preferable that the length of one side is 15-100 cm, and it is more preferable that it is 20-70 cm.

  Moreover, the dimension in the state in which the drape 1 is folded is not particularly limited, but the length of one side is preferably 5 to 40 cm, and more preferably 7 to 20 cm.

  Next, based on FIG. 3, the folding method of the drape 1, that is, how the drape 1 is folded and in its folded state will be described.

  In FIG. 3, the direction of the notch 2 is defined as the Y-axis direction and the direction perpendicular to the direction of the notch 2 is defined as the X-axis direction with the drape 1 being expanded. Moreover, in FIG. 3, the mountain fold of the fold of the drape 1 is shown with a dashed-dotted line, and a valley fold is shown with a broken line. In FIG. 3, when the drape 1 is folded, the portion to be displaced is hatched. Further, the scales of FIGS. 3A to 3H are not constant.

  First, as shown in FIG. 3A, the unfolded drape 1 without a crease is placed on a predetermined work table (not shown). In this case, the unclean surface of the drape 1 faces the work table, and the clean surface 11 faces the opposite side so that it does not contact the work table.

[First folding from unfolded state]
Next, as shown in FIG.3 (b), the drape 1 is folded in two so that the clean surface 11 may become inside. In this case, the portion 51 on the left side of the drape 1 in FIG. 3B is displaced and is valley-folded so that the crease 41 is attached in the Y-axis direction. As a result, a fold line 41 is formed on the extension line of the notch 2.

  In addition, when the drape 1 is folded in two, the two portions that are folded in two are completely overlapped. Thereby, the clean surface 11 is not exposed.

  In each of the subsequent two folds, the two portions that are folded in two are completely overlapped with each other.

  Thus, the drape 1 is folded so that the clean surface 11 is on the inner side in the first folding from the unfolded state. Thereby, when the drape 1 is folded, it is possible to prevent the clean surface 11 from coming into contact with the work table in the first folding, and, as will be described later, only the corners are folded to hold the gripping portion. Since the clean surface 11 is not exposed until 3 is formed, the drape 1 can be folded while the clean surface 11 is kept clean.

  Also, when unfolding the folded drape 1, the clean surface 11 is exposed at the end except for the grip portion 3, so that most of the clean surface 11 excluding the grip portion 3 portion is used until the drape 1 is used. It can be kept clean.

[The second folding from the unfolded state]
Next, as shown in FIG. 3C, the drape 1 is further folded into two. In this case, the lower part 52 in FIG. 3C of the drape 1 is displaced, and valley folding is performed so that the crease 42 is attached in the X-axis direction.

  Thus, the drape 1 is folded so that the crease 42 is attached in a direction perpendicular to the direction of the notch 2 in the second folding from the unfolded state. Thereby, when expanding the folded drape 1, it can be expanded easily and reliably with one hand.

[The third folding from the unfolded state]
Next, as shown in FIG. 3 (d), of the two parts 61 and 62 (see FIG. 3 (c)) that are folded in two in the second folding, The portion 61 on the front side with respect to the paper surface is further folded in two. In this case, the upper side portion 611 in FIG. 3D of the front side portion 61 is displaced and viewed from the front side with respect to the paper surface in FIG. 3D so that the fold 43 is attached in the X-axis direction. Make a valley fold in the state. In other words, the front side portion 61 is valley-folded such that the front side surface thereof is a valley with respect to the surface, that is, the paper surface in FIG.

[Folding for the fourth time from the unfolded state]
Next, of the two portions 61 and 62 (see FIG. 3C) that are folded in two in the second folding, the portion 62 on the back side with respect to the paper surface in FIG. Fold it in two. In this case, as in the third folding, as shown in FIG. 3 (e), the upper part 621 in FIGS. 3 (d) and 3 (e) of the rear part 62 is displaced in the X-axis direction. As shown in FIG. 3D, valley folding is performed so that a crease 44 is formed when viewed from the back side. In other words, the back side portion 62 is valley-folded so that the surface, that is, the back side surface of the paper surface in FIG.

Thereby, when viewed from the left side in FIG. 3E, the drape 1 is folded into an M shape.
Note that the order of the fourth folding and the third folding may be reversed.

[Fifth folding from the unfolded state]
Next, as shown in FIG. 3F, the drape 1 is further folded into two. In this case, the portion 53 on the right side of the drape 1 in FIG.
In this state, one of the corners is located on the outermost side.

[Formation of grip part 3]
Next, as shown in FIG. 3 (g), only the corner portion of one part on the front side of the drape 1 in FIG. Form. In this case, the lower left portion 54 of one part on the front side with respect to the paper surface in FIG. 3G of the drape 1 is displaced so that the inclination angle is −45 ° when the X axis is inclined at 0 °. A valley fold is made so that the crease 46 is attached in the direction. In this way, the grip portion 3 is formed by bending only the outermost corner portion so that the clean surface is exposed.

  As described above, as shown in FIG. 3 (h), the drape 1 is folded so that the corner portion forming the grip portion 3 is located on the outermost side.

  The folded drape 1 is preferably subjected to a predetermined process so that its crease, that is, each crease is formed reliably. As this treatment, for example, a predetermined weight is placed on the folded drape 1.

  The drape 1 folded in this way is stored and stored in, for example, a predetermined container or the like, and is taken out from the container and used in an expanded manner when necessary. When unfolding the folded drape 1, the grip portion 3 is held with one finger and the drape 1 is pulled up. At this time, the drape 1 is shaken up and down several times as necessary. Thereby, the drape 1 can spread reliably.

  Thus, since the drape 1 is folded as described above, when the drape 1 is expanded, the grip portion 3 located on the outermost side can be easily gripped with one hand, and the notch 2 is obstructive. Rather, it can be easily and reliably spread with one hand.

  Further, since the grip part 3 is formed by bending the outermost corner at the end, the drape 1 can be folded while the clean surface 11 is kept clean until the grip part 3 is finally formed. .

  Note that the drape of the present embodiment is folded so that a crease is formed in the direction of the notch 2 in the first fold from the unfolded state, and the fold is in a direction perpendicular to the direction of the notch 2 in the second fold. The drape of the present invention is folded in the direction of the incision 2 in at least one of the first folding and the second folding from the unfolded state. It suffices to fold so that a crease is formed in a direction perpendicular to the fold, and to fold a plurality of times so that a corner including any one vertex of the quadrangle is located on the outermost side.
