Description

The present invention relates to sheet-like drape covering the coated object is a patient in a medical facility.

  Conventionally, when a medical procedure is performed in a medical facility such as an operating room or a hospital room, the surface of a medical article such as a body surface of a patient or a medical device defined as an unclean area is covered with a medical drape. Isolating the clean area from the unclean area has been done.

  In the drape that covers the patient, an opening for exposing the treatment target site of the patient from the drape is provided. For example, in the medical drape of Patent Document 1, an open window lid that covers a hole (opening) of the base cloth is fixed to the base cloth, and along a rectangular frame-shaped perforation provided on the open window cover. By separating a part of the fenestration lid, the patient's body surface is partially exposed.

On the other hand, Patent Document 2 discloses an ophthalmic drape to be attached to the eyelid around the eye, and an opening for exposing the eyeball is provided in the drape sheet. In the drape, two perforations extending from the opening of the sheet to the end of the sheet are formed, and the sheet is divided into two along the perforations and pasted on the upper and lower eyelids, respectively. The sheet is appropriately arranged according to the size and shape of the sheet.

  By the way, when the medical treatment is finished, the drape covering the patient is removed from the patient, but the treatment is finished with a tube inserted into the patient's body, such as epidural anesthesia or central venous catheter treatment. In this case, since the tube is placed in the body through the opening of the drape, it is difficult to remove the drape in this state.

  Therefore, after the drape is cut using scissors from the opening portion to the peripheral portion, the drape is removed so that the tube passes through the cut portion. However, the work of tearing the drape with scissors is a large amount of drape, and it is necessary to be careful not to injure the patient under the drape with scissors. Will become bigger. Also, the time required to remove the drape increases.

  On the other hand, as a method of easily tearing the drape without using scissors, perforations as shown in Patent Document 1 and Patent Document 2 are formed in advance in the drape, and when the drape is removed, along the perforations. It is conceivable to tear the drape by hand. However, as described in Patent Document 2, since the perforation is formed through the sheet, the dirty area and the clean area communicate with each other through the perforation, and the clean area at the time of medical treatment Isolation from unclean areas can be difficult.

  FIG. 1 is a plan view showing a medical drape 1 according to a first embodiment of the present invention. The drape 1 is a sterilized sheet-like member, and cleans the patient's body surface, which is an unclean area, by covering the patient undergoing medical treatment such as surgery in a medical facility such as an operating room or a hospital room. Isolate the area.

  As shown in FIG. 1, the drape 1 includes a rectangular drape body 2 having a circular opening 20 formed at a substantially center, and a surface 21 of the drape body 2 facing the patient (that is, the side facing the unclean area). The adhesive layer 3 is formed around the opening 20 in the following description, which is referred to as the “lower surface 21”, but does not have to be physically facing downward during use. When covering the patient with the drape 1, the adhesive layer 3 is placed in a state where the drape main body 2 is disposed so that the opening 20 is positioned on a site where medical treatment is performed (hereinafter referred to as “treatment target site”). The treatment target site is exposed from the drape main body 2 by being attached to the skin around the treatment target site. In other words, in a state where the patient is covered by the drape 1, the patient's body surface is partially exposed through the opening 20, and the treatment target site of the patient can be easily accessed through the opening 20. can do.

  In the drape main body 2, in a rectangular elongated region 230 (shown surrounded by a two-dot chain line in FIG. 1) passing through the opening 20, the surface 22 opposite to the patient (that is, a clean region where the practitioner stands). The two opposing cut lines 25a and 25b (which are called “upper surface 22”, but need not physically face upward when used) are not penetrated into the lower surface 21. That is, a cut line extending vertically from the opening 20 is formed. In the following description, a portion included in the region 230 of the drape main body 2 is referred to as a “non-penetrating cut portion 23”, and a portion 24 other than the non-penetrated cut portion 23 of the drape main body 2 (ie, the non-penetrating cut portion 23 in FIG. 1). A portion continuously extending to the non-penetrating cut portion 23 on both the left and right sides of the cut portion 23) is referred to as a “cover portion 24”.

  Each of the cut lines 25a and 25b is formed by intermittently and linearly arranging a plurality of non-through cuts formed on the upper surface 22. In FIG. 1, for convenience of illustration, the cut lines 25 a and 25 b are simplified and drawn as a set of broken lines, but the actual shape of the plurality of cut lines of the cut lines 25 a and 25 b is different from that shown in FIG. 1. (The same applies to FIG. 4). The detailed shape of the plurality of cuts of the cut lines 25a and 25b will be described later.

  In the non-penetrating cut portion 23 of the drape body 2, one cut line 25 a extends from the sheet end portion of the drape 1 (that is, the outer peripheral edge of the drape body 2) toward the opening 20 (that is, toward the inside of the drape body 2). E) It extends in a straight line. The other cut line 25 b is disposed on the extension of the cut line 25 a on the side opposite to the cut line 25 a of the opening 20 and extends linearly from the sheet end of the drape 1 toward the opening 20. In the medical facility, the patient is covered by the drape body 2 (that is, the non-penetrating cut portion 23 and the covering portion 24) of the drape 1, and after the medical treatment is performed through the opening 20, the drape 1 is placed on the patient. Removed from.

  By the way, for example, when the treatment is terminated with a tube inserted into the patient's body, such as epidural anesthesia or central venous catheter treatment, the tube is left in the body through the opening 20 of the drape 1. In this state, it is difficult to remove the drape. In such a case, when the drape 1 is removed from the patient, the non-penetrating cut portion 23 of the drape main body 2 is cut by the practitioner's hand without using scissors or other scissors. Torn along either one (or both). At this time, the non-penetrating cut portion 23 is usually torn from the opening 20 side toward the sheet end portion of the drape 1. In the following description, the direction from the opening 20 side toward the sheet end along each cut line 25 (that is, the direction in which the cleavage is extended when the non-penetrating cut part 23 is torn) is indicated by each cut line 25 or the “progress” of the cleavage. "Direction".

  FIG. 2 is an enlarged plan view showing a portion of the drape 1 near the upper cut line (that is, the cut line 25a) in FIG. Hereinafter, the shape and arrangement of the plurality of cuts of the cut line 25 will be described with reference to FIG. In addition, in the lower cut line (that is, the cut line 25b) in FIG. 1, the shape and arrangement of the plurality of cuts are the same except that the cut lines 25a are different in 180 ° direction.

  As shown in FIG. 2, each of the plurality of cuts 251 of the cut line 25 is one side (that is, clockwise in FIG. 2) with respect to the traveling direction of the cut line 25 (that is, the upward direction in FIG. 2). Are arranged on the right side in FIG. 2 of a plurality of linear first cuts (hereinafter referred to as “251a”) that are inclined by a predetermined angle in the direction of A plurality of linear second cuts (hereinafter referred to as “251b”) inclined by a predetermined angle to the other side (ie, counterclockwise direction in FIG. 2) with respect to the traveling direction of the cut line 25. Including.

  Each first cut 251a and each second cut 251b have the same inclination with respect to the traveling direction. In the present embodiment, the first cut 251a and the second cut 251b are about 45 ° clockwise and about 45 ° counterclockwise, respectively. That is, each first cut 251a is inclined in a direction in which an end on the traveling direction side approaches the plurality of second cuts 251b, and each second cut 251b has a plurality of first cuts 251a on the end on the traveling direction side. Tilt in the direction of approaching.

  In the cut lines 25, a plurality of first cuts 251a are arranged in three rows parallel to the traveling direction of the cut lines 25, and the plurality of second cuts 251b are also cut adjacent to each array of the first cuts 251a. It is arranged in three rows in parallel with 25 traveling directions. In the following description, the three arrays of the first cuts 251a are respectively referred to as “first cut lines 252a”, and the three arrays of the second cuts 251b are respectively referred to as “second cut lines 252b”. The first cut row 252a and the second cut row 252b are alternately arranged in the width direction of the cut line 25 so that the second cut row 252b always exists on the right side in the traveling direction of the first cut row 252a. The In other words, from the left side to the right side in FIG. 2, combinations of three sets of the first cut row 252a and the second cut row 252b are arranged in the width direction.

  In each combination of the first cut row 252a and the second cut row 252b, the plurality of first cuts 251a are inclined toward the second cut row 252b while moving in the direction of progress of the cleavage, and the plurality of second cuts 251b. However, it inclines toward the 1st notch row | line | column 252a while it goes to the advancing direction of cleavage. The plurality of first cuts 251a included in the first cut row 252a are adjacent in the width direction to the plurality of second cuts 251b included in the second cut row 252b, respectively, and a pair of adjacent first cuts 251a and the second notch 251b are in the shape of “C”.

  In each first cut row 252a, end portions on the traveling direction side of the plurality of first cuts 251a and end portions on the opposite side to the traveling direction are respectively located on straight lines parallel to the traveling direction. Similarly, in the two cut rows 252b, the end portions on the traveling direction side of the plurality of second cuts 251b and the end portions on the opposite side to the traveling direction are respectively positioned on straight lines parallel to the traveling direction.

  Further, in the first cut row 252a, an extension line 254 (indicated by a broken line in FIG. 2) extending from the end portion on the traveling direction side of the first cut 251a along the inclination in the vicinity of the end portion. It intersects with the second cut 251b arranged on the traveling direction side (the same applies to the second cut row 252b). By arranging the first notch row 252a and the second notch row 252b in this way, for example, even if the cleavage at the time of tearing progresses while slightly tilting from the first notch 251a to the next, the next first notch 251a. Even if the cleavage proceeds while slightly tilting to the right, it will reach one of the second cuts 251b. As described above, in each combination of the first cut row 252a and the second cut row 252b of the cut line 25, the plurality of cuts 251 reach the cut extending from the cut 251 that is torn immediately before the non-penetrated cut portion 23 is torn. It is arranged to cross the planned range.

  FIG. A is a figure which shows the cross section which cut | disconnected the drape 1 in the position of AA in FIG. 1 and FIG. FIG. A shows a cross section in the vicinity of the cut line 25. For convenience of illustration, the width of each cut 251 is drawn larger than the actual width. FIG. As shown in A, the drape main body 2 has a two-layer structure in which two sheet-like members 41 and 42 are laminated. In the following description, the sheet-like member opposite to the patient is referred to as “first sheet 41. "A sheet-like member facing the patient is referred to as a" second sheet 42 ". The first sheet 41 is formed with a plurality of through-cuts 411 that are intermittently and linearly arranged, and the second sheet 42 that is smooth (that is, no cuts are formed) is one of the first sheets 41. A plurality of cuts 251 of the cut lines 25 are formed by closing one of the plurality of through cuts 411 (that is, the lower side) by being laminated on the surface by extrusion lamination or the like.

  The first sheet 41 and the second sheet 42 are preferably formed of a polyolefin-based plastic film such as a polyethylene film or a polypropylene film. In the present embodiment, the first sheet 41 and the second sheet 42 are formed of a transparent or translucent unstretched film. The total thickness of the first sheet 41 and the second sheet 42 (that is, the thickness of the drape body 2) is preferably 60 μm to 100 μm. When the thickness of the drape body 2 is 60 μm or more, the strength of the drape 1 can be sufficiently secured, and when the thickness of the drape body 2 is 100 μm or less, the texture of the drape 1 is softened. Thus, the adhesion of the drape 1 to the patient can be improved.

  The first sheet 41 and the second sheet 42 are subjected to antistatic treatment. For this reason, it can prevent adsorbing the fiber piece (so-called lint), dust, etc. which float in the air. In the antistatic treatment, for example, when forming a plastic film that becomes an original member of the first sheet 41 and the second sheet 42, an antistatic material (for example, an anionic surfactant, a cationic surfactant) is added to the plastic material. Agent, nonionic surfactant, amphoteric surfactant). The antistatic treatment may be performed by coating the surface of the plastic film with an antistatic material.

  FIG. B is a figure which shows the cross section which cut | disconnected the drape 1 in the position of BB in FIG. 1 and FIG. FIG. In B, the cross section of the cutting line 25 vicinity is shown. FIG. As shown in B, the adhesive layer 3 is intermittently formed so as to overlap a part of the cut line 25 of the drape main body 2 in a plan view (that is, a plurality of cuts 251 overlapping the adhesive layer 3 in the plan view). The non-penetrating cut portion 23 has adhesive layer cut lines 26 that are a plurality of cuts 261. FIG. In B, for convenience of illustration, the width of each cut 261 is drawn larger than the actual width. The plurality of cuts 261 are formed through the adhesive layer 3, and one opening (that is, the upper opening in FIG. 3.B) of the plurality of cuts 261 is closed by the drape main body 2.

  When the non-penetrating cut portion 23 of the drape 1 shown in FIG. 1 is torn, the drape body 2 and the adhesive layer 3 are moved from the edge of the opening 20 to the cut line 25 and the adhesive layer cut line 26 (see FIG. 3.B). After being torn along and reaching the end of the adhesive layer 3, only the drape body 2 is torn along the cut line 25 (see FIG. 2).

  As described above, in the drape 1, the cut lines 25 as the plurality of cuts 251 are provided in the non-penetrating cut portion 23 of the drape body 2, and are necessary when the drape 1 is removed from the patient. Accordingly, the non-penetrating cut portion 23 is torn along the cut line 25. Further, in the non-penetrating cut portion 23, a plurality of cuts 251 of the cut line 25 are made non-penetrating with respect to the drape main body 2 (that is, a plurality of cuts 251 are formed on the upper surface 22 of the drape main body 2 and formed on the lower surface 21. Against the other). Thereby, the clean area | region in a medical facility can be isolated from the patient's body surface which is an unclean area | region at the time of medical treatment, and tearing of the drape 1 after medical treatment can be made easy. As a result, the drape 1 can be removed easily and quickly. In the drape 1, the cut lines 25 are formed by intermittently arranging the plurality of cuts 251, so that the strength of the drape 1 can be sufficiently secured.

  When a medical procedure is performed, it is preferable to reduce the time required for the medical procedure as much as possible from the viewpoint of reducing the burden on the patient. As described above, the drape 1 can be easily torn along the cut line 25 and can be quickly removed to reduce the time required for the medical treatment, so that the medical treatment is performed in the medical facility. Particularly suitable for patient covering. Moreover, since the drape 1 can isolate a clean area | region from an unclean area | region by making the cut line 25 non-penetrating, it is especially suitable for the drape which covers the patient's body surface which tends to become an unclean area | region by perspiration.

  In the drape 1, the adhesive layer 3 is disposed around the opening 20 on the lower surface 21 of the drape body 2, and an adhesive layer cut line 26 that overlaps the cut line 25 formed in the drape body 2 is formed in the adhesive layer 3. By doing so, it is possible to ensure the ease of tearing of the non-penetrating cut portion 23 even at the site where the adhesive layer 3 is provided, while preventing the opening 20 from shifting from the treatment target site of the patient.

  By the way, as a method of forming a cut line such as a perforation on a sheet-like base material, in a state where a cylindrical roll cutter provided with a plurality of cutting blades on the outer surface is rotated, the sheet-like base material is A method is known in which small through cuts are formed at a plurality of locations on a substrate by a plurality of cutting blades by passing between the outer surface of the roll cutter and a support member. In this method, when the cut line is not penetrated with respect to the sheet-like substrate, it is necessary to accurately control the distance between the cutting blade of the roll cutter and the sheet-like substrate. In particular, when the sheet-like substrate is thin, more accurate control is required for the distance.

  On the other hand, in the drape 1, the drape main body 2 has a two-layer structure of the first sheet 41 and the second sheet 42, and one opening of the plurality of through cuts 411 of the first sheet 41 is blocked by the second sheet 42. As a result, a plurality of cuts 251 of the cut lines 25 that are not penetrating the drape main body 2 are formed. In the manufacture of the drape 1, the plurality of through cuts 411 of the first sheet 41 are easily formed by a method using the above-described roll cutter. Therefore, compared with the case where a non-penetrating cut is formed in the drape body having a single layer structure, the cut line 25 can be easily and reliably formed, and the drape 1 can be easily manufactured.

  As described above, in the cut line 25, each of the plurality of cuts 251 is linear. For this reason, the shape of the some cutting blade provided in the outer surface of the above-mentioned roll cutter can be made simple, and the cost concerning manufacture of the drape 1 can be reduced.

  In each combination of the first cut row 252a and the second cut row 252b of the cut line 25, each cut 251 traverses the range where the split extending from the cut 251 that is torn immediately before the non-penetrated cut portion 23 is to be reached is reached. To be arranged. Thereby, when tearing the non-penetrating cut portion 23 of the drape 1, it is possible to prevent the cleavage from deviating from the cut line 25 and extending in a direction different from the traveling direction.

  Further, in each combination of the first cut row 252a and the second cut row 252b, the plurality of first cuts 251a are inclined toward the second cut row 252b and directed to the second cut row 252b. The cut 251b is inclined toward the first cut row 252a while being directed in the progressing direction of the cleavage. Therefore, when the cleavage reaches the first notch 251a or the second notch 251b, the cleavage is directed to the region between the first notch row 252a and the second notch row 252b by the first notch 251a or the second notch 251b. Be guided. Thereby, when tearing the non-penetrating cut portion 23 of the drape 1, it is possible to further reliably prevent the breakage of the tear from the cut line 25.

  Furthermore, the combination of the 1st notch row | line | column 252a and the 2nd notch row | line | column 252b which the notch line 25 arrange | positions closely adjoining the edge part by the side of the advancing direction of each 1st notch 251a and each 2nd notch 251b is 3 Due to the combination, when tearing the non-penetrating cut portion 23 of the drape 1, it is possible to more reliably prevent the breakage of the tear from the cut line 25.

  In the drape 1, since the drape main body 2 (that is, the first sheet 41 and the second sheet 42) is formed of a plastic film, the lint (that is, the fiber piece) when tearing the non-penetrating cut portion 23 of the drape 1 is formed. Occurrence can be prevented. In particular, in this embodiment, since the entire drape body 2 is formed of an unstretched plastic film, the texture of the drape 1 can be softened, and as a result, the adhesion of the drape 1 to the patient is improved. The patient can be covered more reliably.

As described above, in the drape 1, the drape main body 2 (that is, the non-penetrating cut portion 23 and the covering portion 24) is transparent or translucent, so that the drape 1 such as a patient or an operating table is covered with the drape 1. The covered object can be easily visually recognized. As a result, the state of the patient during the medical procedure can be easily confirmed, and the drape 1 can be easily removed from the patient after the medical procedure. In addition, when the patient is covered with the drape 1 before the medical treatment, the covering can be facilitated .

  Next, the drape according to the second embodiment will be described. FIG. 4 is a plan view showing the drape 1a according to the second embodiment, and FIG. 5 is an enlarged view of a part of a cross section obtained by cutting the drape 1a at a position CC in FIG. FIG. As shown in FIGS. 4 and 5, in the drape 1 a, a non-penetrating cut line 25 is formed on the lower surface 21 of the non-penetrating cut portion 23 of the drape main body 2. Other configurations are shown in FIGS. This is the same as the drape 1 shown in B, and the same reference numerals are given in the following description.

  As shown in FIG. 5, the drape body 2 of the drape 1 a has a two-layer structure including a first sheet 41 and a second sheet 42 as in the first embodiment. In the drape 1a, a plurality of through-cuts 411 arranged intermittently and linearly are formed in the second sheet 42, and one opening of the plurality of through-cuts 411 is closed by the smooth first sheet 41. Thus, a plurality of non-penetrating cuts 251 of the cut line 25 are formed. In FIG. 5, the adhesive layer 3 shown in FIG. 4 is also shown.

  In the drape 1a, as in the first embodiment, the cut lines 25, which are a plurality of non-penetrating cuts 251, are provided in the non-penetrating cut portions 23 of the drape main body 2, so that the inside of the medical facility can be used during medical treatment. The clean area can be isolated from the patient's body surface, which is an unclean area, and the non-penetrating cut portion 23 of the drape 1a can be easily torn after the medical procedure. As a result, the drape 1a can be removed easily and quickly.

  As shown in FIG. 5, in the drape 1 a, the adhesive layer 3 is intermittently overlapped with a part of the cut line 25 of the drape main body 2 (that is, a plurality of cuts 251 overlapping the adhesive layer 3 in plan view). A plurality of cuts 261 are formed. In other words, in the region where the adhesive layer 3 is provided, the score line 25 is formed by a notch penetrating the adhesive layer 3. Thus, as in the first embodiment, the opening 20 is prevented from being displaced from the treatment target site of the patient, and the ease of tearing of the non-penetrating cut portion 23 is ensured even in the site where the adhesive layer 3 is provided. can do.

  In the drape 1a according to the second embodiment, a plurality of cuts 251 and a plurality of cuts 261 can be formed simultaneously (that is, by a single cut process), particularly in the region where the adhesive layer 3 is provided. For this reason, FIG. Compared to the case where the cut line 25 is formed on the upper surface 22 opposite to the side where the adhesive layer cut line 26 is formed of the drape main body 2 as in the drape 1 shown in B, the manufacture of the drape 1a is facilitated. can do.

  On the other hand, in the drape 1 according to the first embodiment, FIG. A and FIG. Since the cut line 25 is formed on the upper surface 22 of the non-penetrating cut portion 23 of the drape main body 2 as shown in B, the cut line 25 is formed on the lower surface 21 of the drape main body 2 as shown in FIG. Compared to the above, it is possible to facilitate the visual recognition of the cut line 25 by the practitioner, and to tear the non-penetrating cut portion 23 more easily.

  Next, the drape according to the third embodiment will be described. 6 is a cross-sectional view showing a part of the drape 1b according to the third embodiment. The site | part corresponding to B and FIG. 5 is shown. As shown in FIG. 6, the drape 1 b includes a third sheet 43 stacked on the opposite side of the first sheet 41 from the second sheet 42. Other configurations are shown in FIGS. This is the same as the drape 1 shown in B, and the same reference numerals are given in the following description.

  As shown in FIG. 6, the drape body 2 of the drape 1 b has a three-layer structure including a first sheet 41, a second sheet 42, and a third sheet 43.
