Description

The present invention relates to masks. More specifically, the present invention relates to masks worn when using medical devices that are inserted into the body through the mouth or nose.

Masks cover the nose and mouth of the face and are used to prevent colds, influenza, and the like, and are also used to prevent infection of others. Also, hay fever patients use masks to prevent pollen from entering their noses and mouths. In recent years, due to the spread of the new coronavirus, many people are forced to wear masks on a daily basis. Under such circumstances, there is a need for an endoscopy mask that can be used by a subject undergoing an endoscopy in a hospital to prevent droplets from spreading even during the examination. In addition, the same applies not only to endoscopy, but also to the use of medical equipment that is inserted into the body through the nose or mouth.

For example, a disposable endoscopy mask that fundamentally prevents the spread of droplets caused by a subject's gag reflex or sneezing during an endoscopy, protects the operator, and prevents contamination of the examination room. is known (see, for example, Patent Document 1).

However, the endoscopy mask disclosed in Patent Document 1 is made of a thin material and has a limited hygroscopicity. Therefore, when the filter pieces are wet, they are in close contact with the cheeks and chin of the subject, making them uncomfortable to wear. There is a problem that it is not good.

The subject is wearing the mask 1 in a state where the mask 1 is placed in a position where the In the second covering state, as shown in FIG. 1B, the face is covered with the main body 10 so that the second leg 14 and the mark 70 of the mask 1 are arranged on the upper side, and the through hole 50 is positioned on the subject. The subject is wearing the mask 1 in a state of being placed at a position corresponding to the mouth. The mask 1 is designed to cover the subject's nose and mouth in either the first covering state or the second covering state.

[Main body part 10]
As shown in FIG. 1, the body part 10 is a member that covers the nose and mouth of the wearer's face. As shown in FIG. 1, the main body 10 has a substantially trapezoidal shape when viewed from the side. The substantially trapezoidal shape of the main body 10 includes a linear upper base 11, an arc-shaped lower base 12 protruding outward, a first leg 13 connecting the upper base 11 and the lower base 12 on the upward side, and the upper base 11. It is formed by being partitioned by a second leg 14 that connects the lower bottom 12 on the downward side. The body portion 10 has a support portion 20 attached to the lower base 12 side, and a through hole 50 formed in the upper base 11 side.

As shown in FIG. 2(a), the main body 10 is formed in a substantially elliptical shape when viewed from the front, and as shown in FIG. ing. The elliptical shape of the main body 10 is formed so as to pass through both ends of an imaginary short axis YL extending in the vertical direction and both ends of an imaginary long axis XL extending in the horizontal direction. The elliptical shape of the body portion 10 is formed so that the imaginary major axis XL is longer than the imaginary minor axis YL. The insole 12 shown in FIG. 1 is a curved line that forms the elliptical shape of the body portion 10 when viewed from the front, as shown in FIG.

The upper sole 11, the first leg 13 and the second leg 14 shown in FIG. 1 are arranged on the same axis when viewed from the front as shown in FIG. ing. The imaginary short axis YL, the upper base 11, the first leg 13 and the second leg 14 shown in FIG. 1 are arranged on the same imaginary plane of symmetry VS as shown in FIG. 2(b). The body portion 10 is formed in a three-dimensional shape substantially symmetrical with respect to the virtual plane of symmetry VS. The body part 10 formed in a three-dimensional shape forms an edge part 30 that contacts and covers the face of the subject on the side of the bottom 12 . The main body part 10 formed in a three-dimensional shape forms an inner part 40 that covers the face of the subject with the upper base 11 side separated from the face of the subject.

[Support portion 20]
The support portion 20 is a member that is attached to the body portion 10 and supports the body portion 10 on the wearer's face. As shown in FIG. 2( a ), the support part 20 is a string-like member such as a string or rubber attached to the left and right ends of the main body 10 . The support part 20 is formed in a ring shape so that it can be hung on the ear. Although the support portion 20 in this example is attached to the first surface portion 101 side of the main body portion 10 , it may be attached to the back surface portion 103 side, or may be sandwiched between the first surface portion 101 and the back surface portion 103 . may be installed

[Edge 30]
The edge portion 30 is a portion around the body portion 10 that contacts and covers the face. The edge portion 30 has a shape similar to the contour of the main body portion 10, and as shown in FIG. , it has a substantially elliptical shape when viewed from the front. The edge portion 30 may be provided with a core material such as a wire that retains the shape of the face so that the face can be securely covered.

[Inner part 40]
The inner part 40 is a part inside the main body part 10 that is separated from the face and covers the face. The inner portion 40 has the same shape as the main body portion 10 except for the edge portion, and has a substantially trapezoidal shape when viewed from the side as shown in FIG. 1(a). , and when viewed from the front, it has a substantially elliptical shape. When the subject wears the mask 1, the inner portion 40 side of the main body 10 is separated from the subject's face, so a predetermined space S is defined as shown in FIG.

[Through hole 50]
The through-hole 50 is formed so as to pass through the main body 10 and is a portion through which a device such as an endoscope inserted into the wearer's (subject's) body from the nose or mouth is passed. As shown in FIGS. 1 and 2, the through hole 50 is formed on the first leg 13 side of the upper base 11 . That is, the through-hole 50 is designed to be arranged at a position corresponding to the subject's nose in the first covered state. Since the outside of the through hole 50 is welded, the strength around the through hole 50 in the main body 10 is increased. The through hole 50 is preferably formed at a position where the inner portion 40 and the virtual plane of symmetry VS intersect.

The through hole 50 is formed to have a diameter of 15 mm so that a transnasal endoscope having a diameter of approximately 5 to 8 mm or an oral endoscope having a diameter of approximately 8 to 12 mm can be inserted. The through-hole 50 is formed larger than the diameter of the transnasal endoscope or the transoral endoscope. This is to prevent the medical lubricant applied to the endoscope from scraping off when the endoscope is inserted through the through hole 50 . Moreover, since the space S is formed in the inner portion 40 of the mask 1, the mask 1 is not in close contact with the subject, and the medical staff can easily check the positions of the nose and mouth.

[marks 60, 70]
Marks 60 and 70 are formed on the main body 10 and indicate the direction in which the main body is in the first covering state and/or the second covering state. A mark 60 is a mark that indicates the direction in which the body portion 10 is in the first covering state, and is formed between the bottom sole 12 and the first leg 13 as shown in FIGS. is described. For example, when undergoing transnasal endoscopy, the subject can put on the mask 1 with the face covered by the main body 10 in the first covering state with the mark 60 as a mark.

The mark 70 is a mark indicating the direction in which the main body portion 10 is in the second covered state, and as shown in the figure, is formed between the lower sole 12 and the second leg 14, and is described as, for example, "oralUP↑". ing. For example, when a subject undergoes oral endoscopy, the subject can put on the mask 1 with the face covered by the main body 10 in the second covering state using the mark 70 as a mark.

[Laminated sheet 100]
As shown in FIG. 3 , the laminated sheet 100 is a plate-like member for assembling the main body 10 . In the laminated sheet 100, as shown in FIG. 4, a first surface portion 101, a second surface portion 102 and a back surface portion 103 are laminated in order. The laminated sheet 100 is formed in a substantially rectangular shape having long sides 112a on the upward side, short sides 112b at both ends, and long sides 114 on the downward side. As shown in FIG. 3, the laminated sheet 100 is rolled so that the long side 112a and the short side 112b form a predetermined arc 112c.

As shown in FIG. 3, the laminated sheet 100 is welded under a predetermined pressure and at a predetermined temperature so as to border the long side 112a, the short side 112b and the predetermined arc 112c, thereby forming a welded portion 110W. there is As shown in FIG. 4, one side of the laminated sheet 100 becomes the edge portion 30 and the other side becomes the inner portion 40 with the welded portion 110W as a boundary. The laminated sheet 100 in which the three members are superimposed is laminated together with a reduced thickness at the welded portion 110W. Therefore, the welded portion 110W serves as a restricting portion that restricts the movement of the discharge between the edge portion 30 and/or the inner portion 40. As shown in FIG.

The long side 112a, the short side 112b and the arc 112c of the laminated sheet 100 form the bottom 12 of the assembled main body 10 (see FIG. 1). The laminated sheet 100 is formed in line symmetry, and the portion of the axis of symmetry 113 shown in FIG. 3 is folded to become the first leg 13 of the main body 10 (see FIG. 1).

As shown in FIG. 3 , the laminated sheet 100 is cut into a line-symmetrical triangular shape at the intersection of the axis of symmetry 113 and the downward long side 114 to form a pair of oblique sides 111 . A pair of oblique sides 111 are cut into a semicircular shape to form a pair of semicircular through holes 150 . As shown in FIG. 3, the laminated sheet 100 is welded at a predetermined pressure and at a predetermined temperature so as to border the semi-circular through hole 150 to form a welded portion 150W. The two long sides 114 of the laminated sheet 100 are welded under a predetermined pressure and a predetermined temperature to form the second leg 14 of the assembled main body 10 (see FIG. 1). Two oblique sides 111 of the laminated sheet 100 are welded at a predetermined pressure and at a predetermined temperature to form the upper base 11 of the assembled main body 10 (see FIG. 1). The semi-circular through hole 150 of the laminated sheet 100 becomes the through hole 50 of the assembled main body 10 (see FIG. 1).

[First surface portion 101, second surface portion 102]
The first surface portion 101 and the second surface portion 102 are members for preventing diffusion of droplets. The first surface portion 101 and the second surface portion 102 are formed of nonwoven fabric made of synthetic resin such as polyester, for example. The first surface portion 101 and the second surface portion 102 have a structure in which fine fibers are entwined, and should preferably be able to prevent invasion and diffusion of viruses. In this example, the main body part 10 (laminated sheet 100) is formed by stacking two sheets of a first surface part 101 and a second surface part 102 in order to prevent droplets emitted by the subject from scattering outward.

[Back part 103]
The back surface portion 103 is a member for absorbing the discharged matter. The back surface portion 103 is formed of an absorbent sheet that absorbs droplets, saliva, saliva, and other discharges from the mouth and nose of the subject during an endoscopy. The back surface portion 103 is formed of synthetic resin non-woven fabric in which polyester and rayon are combined. In this example, the back surface portion 103 is formed of a nonwoven fabric containing 55% polyester and 45% rayon. Since the back surface part 103 is made of rayon, it has good hygroscopicity and is comfortable to the touch. Rayon is a natural fiber whose main component is cellulose, which is found in natural plants, and is formed of continuous filament threads. For this reason, the back surface portion 103 containing rayon is soft to the touch and has a dry and comfortable feeling compared to a nonwoven fabric made only of short fibers. The back surface portion 103 may have a large number of linear grooves and small holes may be bored along the grooves so that wastes can be accumulated in the grooves.

〔how to use〕
Next, a method of using the mask 1 configured as described above will be described. In this example, a method for wearing the mask 1 by a subject undergoing transnasal endoscopy or transoral endoscopy will be described. FIG. 5(a) shows a state in which a subject undergoing transnasal endoscopy wears the mask 1, and FIG. 5(b) shows a state in which the subject undergoing oral endoscopy wears the mask 1 It is a figure which shows the worn state. Note that FIG. 5 shows the mask in a transparent state in order to explain the state of the endoscope inside the mask 1 . A medical professional applies a medical lubricant to the transnasal endoscope E1 or oral endoscope E2 in order to reduce the burden of inserting the endoscope into the subject's body.

When transnasal endoscopy is to be performed, the subject wears the mask 1 with the face covered by the main body 10 in the first covering state using the mark 60 on the mask 1 as a guide, and performs transoral endoscopy. In this case, with the mark 70 on the mask 1 as a mark, the direction of covering the face with the main body 10 is set to the second covering state, and the mask 1 is put on after the mouthpiece MP is held in the mouth. When the subject wears the mask 1, as shown in FIG. A predetermined space S is defined. When the subject wears the mask 1, the body part 10 covers the face, the through holes 50 are arranged at positions corresponding to the subject's nose in the first covering state, and the through holes 50 are arranged in the second covering state. is placed at a position corresponding to the mouth of the

As shown in FIG. 5, the medical staff inserts the transnasal endoscope E1 or the transoral endoscope E2 through the through hole 50 of the mask 1 . Since the diameter of the through-hole 50 is larger than the diameter of the nasal endoscope E1 or the oral endoscope E2, the medical lubricant is not scraped off by the through-hole 50, and the nasal endoscope E1 can be inserted up to the nose. The oral endoscope E2 can be inserted up to the mouth. Since the diameter of the through-hole 50 is larger than the diameter of the transnasal endoscope E1 or the oral endoscope E2, the medical staff can use the nasal endoscope E1 or the oral endoscope E1 while confirming the position of the subject's nose and mouth. The endoscope E2 can be passed through the nose. Since the through-hole 50 is formed at the position where the inner portion 40 and the virtual plane of symmetry VS intersect, it can be easily inserted into either the left or right nostril. Moreover, since the space S is formed in the inner portion 40 of the mask 1, the mask 1 is not in close contact with the subject, and the medical staff can easily check the positions of the nose and mouth.

When the subject is being passed through the nasal endoscope E1, the nasal endoscope may stimulate nerves in the mucous membrane of the nose, causing sneezing and droplets. In addition, when the subject is inserted through the nasal endoscope E1 or the oral endoscope E2, the vomiting reflex may be induced and the subject may drip saliva, saliva, or the like, or cough up droplets. In this case, emissions such as droplets, saliva or saliva are absorbed by the back surface portion 103 of the inner portion 40 of the mask 1 . Since the back surface part 103 quickly absorbs the viscous discharge, the absorbed discharge does not easily touch the skin and does not become stuffy or sticky. Since the excreta absorbed by the back surface portion 103 accumulates in the groove portion of the back surface portion 103, the absorbed excretion is less likely to come into contact with the skin.

In addition, since excretion is absorbed on the side of the inner portion 40 away from the subject's face, the absorbed excretion is less likely to come into contact with the wearer's skin. Since the discharged matter absorbed by the inner portion 40 is restricted by the welded portion 110W and does not move toward the edge portion 30, it is difficult for the absorbed discharged matter to come into contact with the wearer's skin. Note that even if the back surface portion 103 cannot absorb all of the discharged matter, the first surface portion 101 and the second surface portion 102 of the two nonwoven fabrics can prevent the diffusion of the discharged matter. By wearing the mask 1, the test subject can be examined without being seen by a medical worker. By wearing the mask 1, the subject can reduce the anxiety of spreading the subject's droplets and the embarrassment of dripping saliva to prevent aspiration.

In this way, the mask 1 prevents the discharge of the subject undergoing the endoscopy from diffusing and the back surface portion 103 absorbs the discharge, so that the discharge does not easily touch the skin and is comfortable to wear. Since the mask 1 is formed in a three-dimensional shape, there are few parts that come into contact with the skin, and the back part 103 is made of a material that feels good on the skin, so it is comfortable to wear. The mask 1 can be used properly according to examinations such as transnasal endoscopy and oral endoscopy. The wearing state of the mask 1 can be judged at a glance according to the type of endoscopy.

The mask 1 can cover the subject's nose and mouth in either the first covering state or the second covering state, as shown in FIG. By wearing 1, the scattering of droplets is reduced. For this reason, the risk of droplet infection is reduced for medical staff, and they can work on endoscopy with peace of mind. In addition, since the space S is formed between the subject and the mask 1, the medical staff can easily operate the endoscope.

[Second embodiment]
A second embodiment of the present invention will be described based on the drawings. FIG. 6(a) is a left side view of a subject undergoing transnasal endoscopy wearing a mask 1, and FIG. It is a left view in the case of wearing. In the second embodiment, the same reference numerals are assigned to the same parts as in the first embodiment described above, and detailed description thereof will be omitted.

[Transparent portion 80]
The transparent portion 80 is a member that is formed in the main body portion 10 and that is entirely or partially transparent or translucent. The transparent portion 80 is formed of, for example, a synthetic resin film such as polyester. The transparent portion 80 may be attached to the first surface portion 101 or the second surface portion 102 or may be formed integrally with the first surface portion 101 or the second surface portion 102 . Since the transparent part 80 is arranged on the main body part, the medical staff can see the endoscope inside the mask 1 and check the scale attached to the insertion part of the endoscope. Therefore, the medical staff can operate the endoscope while observing the nose and mouth through the transparent portion 80 . In addition, when a medical professional is performing an endoscopic examination on a subject, by looking at the scale of the endoscope through the transparent portion, the distance from the through-hole 50 to the nose or mouth, or the distance from the nose or mouth to the nose or mouth. It is possible to grasp the distance of the disease.

[Dropped portion 90]
The narrowed portion 90 is a member that narrows the diameter of the through hole 50 . The squeezed portion 90 is formed of a stringing portion 91 and a squeezed string 92 . The string passing portion 91 is formed in the body portion 10 so as to border the through hole 50, and is an insertion passage through which the tightening string 92 can be passed. The tightening string 92 is a string-like member that is inserted through the stringing portion 91 . The diameter of the through hole 50 can be narrowed by pulling the squeeze string 92 inserted through the string passing portion 91. - 特許庁A medical worker does not squeeze the through-hole 50 when inserting the endoscope through the nose or mouth, thereby preventing the medical lubricant applied to the endoscope from being scraped off. On the other hand, the medical staff pulls the squeezing string 92 to narrow the diameter of the through hole 50 after the distal end of the endoscope coated with the medical lubricant passes through the through hole. By reducing the diameter of the through-hole 50, there is no gap between the endoscope and the through-hole 50, thus preventing the droplets from spreading.

Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and modifications can be made without departing from the scope and spirit of the present invention. The first surface portion 101 and the second surface portion 102 are not limited to polyester, and may be nonwoven fabric made of other synthetic resin such as polypropylene. As long as the mask 1 defines the space S, the main body 10 may have any shape. In this example, the mask 1 is composed of the first surface portion 101, the second surface portion 102, and two nonwoven fabrics, but the number of nonwoven fabrics used as the surface portion may be one or more. In this example, the through hole 50 is formed to have a diameter of 15 mm, but the size may be appropriately changed according to the type of endoscope to be used and the size of its diameter.

In this example, the support part 20 is formed in a ring shape so that it can be hung on the ear, but an adjustment part for adjusting the size of the ring may be attached, or the mask 1 may be worn without hanging on the ear. It may be in the shape of a string that can be formed. The transparent portion 80 is not limited to polyester, and may be a film made of other synthetic resin such as polypropylene. In this example, the welded portion 110W serves as a restricting portion that restricts movement of waste between the edge portion 30 and/or the inner portion 40 . However, a regulating portion for regulating the movement of the discharged matter may be prepared separately. For example, a dam for blocking the movement of the discharged matter may be adhered by injection molding to the edge 30 side of the back surface 103 and used as the regulating portion.
