Description

  The present invention relates to a drape for ophthalmic surgery used in ophthalmic surgery.

  Conventionally, the entire patient's face during surgery has an opening so that the eye is exposed for the purpose of preventing the eye, which is the surgical field, from being infected during ophthalmic surgery (to keep the eye part sterile). Covered with drape. Such a drape, for example, is provided with an adhesive region that can be attached to the periphery of the opening at the edge of the opening, as disclosed in Patent Document 1, and the eye and the opening are in use at the time of use. The patient's face and drape can be fixed by sticking the adhesive region around the eyes of the combined patient, and the eyes can be kept sterile.

  By the way, when the above-mentioned drape is used, the eye part can be kept sterile, but the drape located in the patient's nose and mouth when in use is flat. It will be in direct contact with the drape. In general, ophthalmic surgery is performed with the patient's consciousness, but if the surgery is performed for a long time with the nose and mouth in contact with the drape, the patient may experience discomfort such as difficulty in breathing. Will be given. In order to eliminate such discomfort, recently, a drape having a support capable of changing its shape at a position corresponding to the vicinity of a patient's nose and mouth when the drape is fixed has been proposed. According to the drape, a minute space for facilitating the patient's breathing can be formed between the drape and the patient's nostril and mouth by bending the support body into a curved shape (arch shape). It is possible to reduce the discomfort of the patient during the operation.

  However, since the patient's face shape varies from patient to patient, the support cannot be bent in advance. In addition, in consideration of sterility, the drape is folded by putting a hand directly between the drape and the patient. I can't do that either. Then, in order to bend the support provided in the vicinity of the nose and mouth so as to form a space between the drape and the patient's nostril and mouth, a doctor after covering the patient's face with drape The patient has to fold the support so that the patient's face (near the mouth) is pressed from the side of the drape surface that does not contact the patient's face, and the patient feels pressure (for example, the nose is pinched) A new problem arises in which the user feels uncomfortable due to the feeling of pressure caused by pressing and the feeling of pressure caused by grabbing the face. In addition, it is possible to create a space between the drape and the patient's nostril and mouth by bending the support in a curved shape. However, as described above, the space is very small and from the viewpoint of air permeability Further improvement is required.

FIG. 1 is an exploded perspective view showing an example of an ophthalmic surgical drape according to an embodiment of the present invention, and FIG. 2 is a perspective view showing an example of an ophthalmic surgical drape according to an embodiment of the present invention.

  As shown in FIG. 1, the drape 10 for ophthalmic surgery of the present invention is provided at a position corresponding to a sheet body 20 that covers the patient's face, and the patient's eye when the sheet body 20 covers the patient's face. When the patient's face is covered with the opening 21 for exposing the patient's eyes, the sheet 20 at a position corresponding to the vicinity of the patient's nose and mouth is curved. A support 22 that can be changed in shape to support it and a slack portion 23 formed by loosening the sheet 20 in the vicinity of the support 22 as shown in FIG. And The ophthalmic surgical drape 10 of the present invention is not particularly limited as long as it satisfies this requirement.

(Sheet body)
The sheet body 20 is an essential component of the drape 10 for ophthalmic surgery of the present invention, and is provided to cover the entire patient's face during ophthalmic surgery. As shown in FIG. 1, the sheet body 20 is provided with an opening 21 at a position corresponding to the patient's eye that is a surgical field when the sheet body 20 covers the patient's face. In addition, although the example provided with the one opening part 21 is shown in FIG. 1, it is good also as providing the opening part 21 in the position corresponding to both eyes.

  There is no limitation in particular about the material of the sheet | seat body 20, The sheet | seat etc. which consist of a conventionally well-known nonwoven fabric and a plastic material can be used suitably. Specifically, a polyester nonwoven fabric or a polyethylene sheet having barrier properties against bacteria and viruses can be used. Moreover, as long as the sheet | seat body 20 can cover a patient's face at least, the shape and magnitude | size will not be limited, For example, the sheet | seat body 20 of 100 cm x 100 cm can be used. Moreover, it is good also as the sheet | seat body 20 which can cover not only a patient's face but a patient's whole body.

  The opening 21 provided in the sheet body 20 may be any opening 21 that can expose the patient's eye during ophthalmic surgery, and the shape and size thereof are not limited. In addition, an adhesive region (not shown) that can be attached to the patient's skin after the opening 21 and the patient's eye are aligned with the periphery of the opening 21 on the back surface of the sheet body 20. ) Is provided. The adhesive region is not particularly limited as long as it can be attached to the patient's skin and has a function of not peeling from the sheet body 20 when attached to the patient's skin, and a conventionally known adhesive tape or the like may be used. it can.

(Support)
In order to prevent the sheet body 20 and the patient's nose and mouth from contacting each other at a position corresponding to the patient's nose and mouth when covering the patient's face, as shown in FIG. A support 22 is provided at a position corresponding to the vicinity of the patient's nose and mouth when the patient's face is covered with the sheet body 20. The support body 22 provided on the sheet body 20 is made of a material whose shape can be changed, and the sheet body 20 can be supported according to the shape of the support body by bending the support body 22 into a curved shape. . Thus, when the patient's face is covered, a space is formed between the sheet body 20 and the patient's nostril and mouth at a position corresponding to the vicinity of the patient's nose and mouth. It can prevent that a mouth part and the sheet | seat body 20 contact directly.

  The material of the support 22 is not limited as long as it is a material that can be changed into a curved shape as described above. For example, a metal plate, wire, resin, or the like that can change the shape, for example, aluminum (Al) is used. Bar and polyethylene bar. Further, the method for providing the support 22 on the sheet body 20 is not limited, and a method for providing the support 22 by adhering the support 22 on the sheet body 20 or the support 22 on the sheet body 20 by an adhesive tape or the like. Examples include a method of pasting.

  The support 22 is formed at a position where a space is formed between the sheet body 20 and the patient so that the sheet body 20 does not contact the patient's nostril and mouth when the sheet body 20 is bent into a curved shape. It can be set as appropriate within the range where it can be formed, and the formation position is not particularly limited. For example, it can be provided near the nose or mouth as shown in FIG.

  Further, the support body 22 has a size and shape that can support the sheet body 20 so that a space is formed between the sheet body 20 and the patient's nostril and mouth as described above. The size and shape are not particularly limited. In addition, as shown in FIG. 1, when the sheet body 20 is arranged on the face, the ear side is the side portion, and the axial direction connecting the both side portions is the horizontal axis direction, the length of the support 22 in the horizontal axis direction is long. When the length is too short, it is difficult to form a space between the nostril portion and the mouth portion and the sheet body 20. As the length of the support body 22 in the horizontal axis direction increases, the space formed between the nostril portion and the mouth portion and the sheet body 20 increases. Therefore, the length of the support body 22 in the horizontal axis direction is to some extent. However, when the support 22 is excessively long, the space formed when the entire support 22 is bent and curved covers the opening 21 that is the surgical field. There is a risk that the visibility of the opening 21 may be hindered. Further, when the support body 22 is excessively lengthened, the sheet body 20 itself held by the support body 22 needs to be enlarged, resulting in a cost problem. Therefore, in consideration of these, the length of the support body 22 is a length that can form a desired space (a space that can facilitate the patient's breathing) between the patient's nostril and mouth and the sheet body 20. That's enough, it doesn't have to be longer. Specifically, the length of the support 22 in the horizontal axis direction is preferably 15 mm or more and 60 mm or less, more preferably 15 mm or more and 45 mm or less, and further preferably 15 mm or more and 30 mm or less.

  Note that the material constituting the support 22 (for example, a metal plate) itself does not always have to have the same length as the support 22, and the material constituting the support 22 is set to be longer than the above length. Only a part of the material may be used as the support body 22 of the present invention (that is, for example, a metal plate may be provided on the entire horizontal axis direction of the sheet body 20 and only a part thereof may be used as the support body 22 of the present invention. ). In this way, by extending the material constituting the support 22 to a portion that is not used as the support 22, the shape of the sheet body 20 can be changed using the portion. For example, by extending the material (metal plate) constituting the support 22 to the vicinity of the supplementary container 35 described later, the angle of the supplementary container 35 can be adjusted using the portion.

  However, in the present specification, the support body 22 is merely a function of “supporting the sheet body in a curved shape corresponding to the vicinity of the patient's nose and mouth when the patient's face is covered with the sheet body”. Only the portion having the function is indicated, and the portion not having the function is not referred to as the support 22.

(Loose part)
In order to change the shape of the support 22 so that the mouth and nose of the patient do not come into contact with the sheet body 20 (bend in a curved shape), a doctor or the like covers the patient's face with the sheet body 20 The patient has no choice but to fold the support 22 so as to push the vicinity of the patient's nose and mouth from the surface direction of the support 22 that is not in contact with the body 20, that is, press the patient's face. In addition, the user feels uncomfortable feeling due to being pressed near the mouth. In view of this, in the drape 10 for ophthalmic surgery of the present invention, a slack portion 23 formed by loosening the sheet body 20 is provided in the vicinity of the support body 22 as shown in FIG.

  By providing the slack portion 23 in the vicinity of the support body 22, the shape of the support body 22 can be changed from the back surface direction of the support body 22 using the slack portion 23 when the shape of the support body 22 is changed. Accordingly, doctors and the like can change the shape of the support body 22 without squeezing the vicinity of the patient's nose and mouth, and when the support body 22 is bent, the nasal part and the vicinity of the mouth are compressed. Discomfort felt by the patient can be prevented. The vicinity of the support body 22 means a position where the shape of the support body 22 can be changed from the back surface direction of the support body 22 using the slack portion 23.

  Furthermore, according to the drape 10 for ophthalmic surgery of the present invention in which the slack portion 23 is provided in the vicinity of the support body 22, the shape of the support body 22 is changed using the slack portion 23, and then the slack portion 23 is removed. By pulling out, a new space can be formed between the nostril and mouth of the patient and the sheet body 20 as shown in FIG. 8, and the patient can easily breathe during the operation. Discomfort caused by contact between the patient's nose and mouth and the sheet 20 can be prevented.

  Hereinafter, the preferable form of the slack part 23 is demonstrated concretely. The ophthalmic surgical drape 10 of the present invention is a slack portion 23 formed by slackening the sheet body 20 in the vicinity of the support 22, and the slack portion 23 is used from the back surface direction of the support 22. The shape is not limited to the above as long as the shape of the support 22 can be changed.

  As shown in FIG. 1, the drape 10 for ophthalmic surgery in one embodiment has a head side when the sheet body 20 is arranged on the face as an upper part, a chin side as a lower part, an ear side as a side part, and an upper part and a lower part. A first fold line 31 positioned in a lower direction than the support 22 and substantially parallel to the horizontal axis direction, where the axial direction connecting the vertical axis is the vertical axis direction and the axial direction connecting both sides is the horizontal axis direction; The first fold line 31 is located in a lower direction than the first fold line 31 and has a second fold line 32 substantially parallel to the first fold line 31. The first fold line 31 is mountain-folded, and the second fold line 32 is As shown in FIG. 2, the slack portion 23 is formed in the vicinity of the support 22 by folding the valley. FIG. 3 is a cross-sectional view taken along line AA showing the cross section of the slack portion 23 in the embodiment. As shown in FIG. 3, according to the embodiment, without pressing the patient's face (without pinching the patient's nose or grasping the patient's face), the hand is inserted into the space formed by the slack portion 23 and supported. It becomes possible to easily change the shape of the support 22 from the back side of the body 22. In addition, when the slack portion 23 is pulled out in the direction of the arrow as shown in FIG. 4, a new space for facilitating the patient's breathing is formed in the vicinity of the patient's nose and mouth, The patient's breathing during the operation can be facilitated.

  The slack portion 23 only needs to be provided at a position where the shape of the support 22 can be changed from the back surface direction of the support 22. However, as shown in FIG. It is preferable to be provided. By providing the slack portion 23 so as to overlap the support body 22, the support body 22 can be easily deformed into a curved shape from the back surface direction of the support body 22. Further, the slack portion 23 may be provided at a position corresponding to the patient's mouth when the sheet body 20 covers the patient's face.

  The interval between the first fold line 31 and the second fold line 32 for forming the slack portion 23 can be appropriately set according to the position where the slack portion 23 is formed. When the distance between the first fold line 31 and the second fold line 32 for formation is narrow, the slackness of the slack portion 23 to be formed becomes small, and the shape of the support 22 is changed by operating from the back side. It becomes difficult to make it. Further, when the interval between the first fold line 31 and the second fold line 32 is narrow, a sufficient space cannot be secured when the slack portion 23 is pulled out. Further, when the distance between the first fold line 31 and the second fold line 32 is wide, a new space for facilitating the breathing of the patient formed when the slack portion 23 is pulled out is formed in the shape. It becomes difficult to hold it as it is. Considering such points, the distance between the first fold line 31 and the second fold line 32 is preferably 10 mm or more and 200 mm or less, more preferably 10 mm or more and 100 mm or less, and 30 mm or more and 50 mm or less. Is more preferable.

  Further, in the sheet body 20 forming the slack portion 23, the sheet bodies 20 facing each other are joined at two positions corresponding to positions where the both ends of the mouth are sandwiched when at least the sheet body 20 covers the patient's face. It is preferable. Thereby, a new space formed when the slack portion 23 is pulled out can be easily formed into a bag-like space, and the space can be held in its shape. Furthermore, since the bag-like space that is formed by the slack portion 23 being pulled out and is held in its shape becomes a larger space than the mouth portion, it is possible to make the patient's breathing easier. It is more preferable that at least two positions where the sheet bodies 20 are bonded are bonded at two positions corresponding to positions where both ends of the mouth portion are sandwiched, in other words, at positions corresponding to the vicinity of both ends of the support body 22. FIG. 9 is a perspective view of an ophthalmic surgical drape showing an example in which the sheet bodies 20 forming the slack portion 23 are indirectly joined with a tape 36 or the like so as to be closed.

  In addition, as shown in FIG. 10A, for joining the sheet bodies 20, joining the sheet bodies 20 directly with the double-sided tape 36 or the like, and stitching the sheet bodies 20 directly together. In addition to joining by means of, indirect joining that covers the sheet bodies 20 with a single-sided tape 37 or the like so as to close the sheets 20 as shown in FIG. The sheet bodies 20 may be joined by either one of direct joining and indirect joining, or the sheet bodies 20 may be joined by combining direct joining and indirect joining. FIG. 10A is a cross-sectional view of a joint portion showing an example of directly joining sheet bodies, and FIG. 10B is a cross-sectional view of the joint portion in FIG. Moreover, the joining of the sheet bodies 20 described above can be suitably applied to other forms of the slack portion 23 described later.

  Next, another preferred embodiment of the slack portion 23 will be described with reference to FIGS. 5 and 6 are cross-sectional views of the slack portion 23 in another embodiment.

  As shown in FIG. 5, the slack portion 23 may be a slack portion 23 formed by repeating a plurality of folding lines in a mountain fold and a valley fold. According to the slack portion 23 in this form, a wider space can be formed between the vicinity of the patient's nostril and mouth and the sheet body 20 when the slack portion 23 is pulled out. There is no particular limitation on the number of times that the folding line is repeatedly folded into a mountain or a valley, and the above-described spacing can be suitably used for the spacing between the folding lines. The intervals between the folding lines may be made different. For example, the intervals between the folding lines may be defined so that the space constituting the slack portion 23 gradually increases, and the slack portion 23 is configured. The interval between the folding lines may be defined so that the interval to be gradually reduced. Furthermore, you may prescribe | regulate the space | interval of folding lines so that the space which comprises the slack part 23 may change at random.

  Further, as shown in FIG. 6, the slack portion 23 may be a slack portion 23 formed by folding at least four folding lines in the order of mountain fold, valley fold, valley fold, and mountain fold. Since the slack portion 23 of this form has a bag-like shape in advance, a larger bag-like space can be formed when the slack portion 23 is pulled out.

(Supplementary container)
Further, as shown in FIG. 2, a supplement container 35 for supplementing the liquid generated during the operation may be provided on the sheet body 20. The supplement container 35 is provided to supplement the liquid generated during the operation, and is an arbitrary configuration in the drape 10 for ophthalmic surgery of the present invention.

  The supplement container 35 may be any container having a function of holding a liquid, and a conventionally known vinyl pack or the like can be suitably used. There is no particular limitation on the position where the supplementary container is provided, and the supplemental container can be appropriately provided at a location where the liquid easily flows. As described above, during the operation, the support body 22 is bent into a curved shape, and the sheet body 20 is supported according to the shape. Therefore, as shown in FIG. It is preferably formed in the vicinity of the part. Moreover, it is good also as a structure which connects the tube etc. for discharging | emitting a liquid to the supplement container 35, and discharges | emits a liquid regularly with the said tube.

  As described above, the description has been made centering on the drape for ophthalmic surgery in which the sheet body 20 is provided with one support 22 and one slack portion 23 as shown in FIG. It is good also as providing a pair of support body 22 and a pair of slack part 23 in a position, respectively. FIG. 7 shows a perspective view of an ophthalmic surgical drape 40 in which a pair of support bodies 22 and a pair of slack portions 23 are respectively provided at positions that are substantially symmetrical with respect to the opening 21. In addition, about the support body 22 and the slack part 23 which comprise the drape 40 for ophthalmic surgery, it is the same as that of the above, and description is abbreviate | omitted.

  As shown in FIG. 7, the drape 40 for ophthalmic surgery according to one embodiment is provided with a pair of support bodies 22 and a pair of slack portions 23 at positions that are substantially symmetrical with respect to the opening 21.
