<First Embodiment>

The infection prevention device 10 according to the first embodiment prevents droplet infection such as a virus and airborne infection between a practitioner who performs acupressure, massage, acupuncture and moxibustion, and a patient who receives the treatment. The infection control device 10 is placed between the bed on which the patient lies and the practitioner sitting on a chair. The patient's bed posture is preferably, but not limited to, lying on his back. The practitioner does not have to be sitting in a chair.

As shown in FIGS. 1 to 3, the infection control device 10 includes a support 20 arranged on a floor surface or the like, and a cover 30 hanging from a support portion 23 of the support 20.

The support 20 connects two support bases 21 arranged so as to be in contact with the floor surface, two columnar columns 22 extending substantially vertically upward from each support base 21, and two support columns 22. It has a support portion 23 and an auxiliary beam 24. The upper direction is the upward direction in the direction of gravity.

The form of the two support bases 21 is not particularly limited as long as they can be stably arranged on the floor surface. For example, there may be only one support base 21. The two columns 22 are members of the same shape extending substantially vertically upward from the respective support bases 21. The direction in which the support column 22 extends from the support base 21 is not necessarily limited to the vertical upper direction, and may be inclined with respect to the vertical upper direction.

The support portion 23 is a portion that supports the cover 30. The support portion 23 extends horizontally between the two columns 22. The auxiliary beam 24 is connected to the two columns 22 on the side closer to the floor surface than the support portion 23. The support portion 23 is a member for ensuring the strength of the support body 20. Therefore, if the strength of the support 20 can be sufficiently secured, the auxiliary beam 24 may not be provided.

The cover 30 is a transparent film-like member that allows the practitioner to see the patient and perform the treatment, and prevents droplets between the practitioner and the patient. The cover 30 includes one central cover 31 and two side covers 32. Transparent means translucent as long as the opposite side can be seen.

The central cover 31 has a substantially rectangular shape, and the side end, which is one of the short sides, is fixed to the substantially central portion of the support portion 23 in the extending direction. The central cover 31 hangs downward due to gravity. At the lower end of the central cover 31, a weight 31A is provided to prevent the central cover 31 from rolling up and maintain a hanging state. The downward direction is the downward direction in the direction of gravity. The lower end is the lower end in the direction of gravity. The weight 31A may not be provided.

Each side cover 32 has a substantially rectangular shape, and the side end, which is one of the short sides, is fixed to the side of the support portion 23 close to the support column 22. That is, the two side covers 32 are arranged on both sides of the central cover 31 in a direction perpendicular to the thickness direction of the central cover 31 and in a direction perpendicular to the hanging direction X of the central cover 31. The side cover 32 hangs downward due to gravity. At the lower end of the side cover 32, a weight 32A is provided to prevent the side cover 32 from rolling up and to maintain the hanging state. The weight 32A may not be provided.

In the side cover 32, the side side on which one of the long sides is located is fixed to the support column 22. Therefore, the position of the side cover 32 is held at an appropriate position for infection prevention. The side cover 32 does not have to be fixed to the support column 22. The side side opposite to the side fixed to the support column 22 of the side cover 32, that is, the side side close to the center cover 31 has an overlapping portion 33 that overlaps the side side of the center cover 31. There is. The overlapping portion 33 overlaps the side side of the central cover 31 so as to be in contact with the side surface of the central cover 31 in the thickness direction of the central cover 31. The overlapping portion 33 may be slightly separated in the thickness direction without coming into contact with the surface of the central cover 31. The overlapping portion 33 is arranged on the surface side on which the patient is located with respect to the central cover 31. Therefore, the side cover 32 can bend toward the patient without interfering with the center cover 31. Therefore, when the practitioner uses the infection control device 10, it is easy to bend the side cover 32 and pass the arm through while maintaining the position of the central cover 31 appropriately. As a modification, the side cover 32 does not have to overlap with the center cover 31. Further, the overlapping portion 33 may be arranged on the surface side on which the practitioner is located with respect to the central cover 31.

The central cover 31 and the side cover 32 are arranged on the patient side of the support portion 23, not on the practitioner side. Therefore, since the central cover 31 and the side cover 32 are easily bent toward the patient when used by the practitioner, the practitioner can easily pass the arm through. The central cover 31 and the side cover 32 may be arranged on the practitioner side with respect to the support portion 23, or may be arranged between the practitioner side and the patient side.

The width W1 of the central cover 31 (the length in the direction perpendicular to the thickness direction of the central cover 31 and the direction X in which the central cover 31 hangs down (for example, the downward direction) (for example, the horizontal direction)) is particularly limited. Although not, it is preferably longer than the patient's head and not too long so that the practitioner can pass both arms across the central cover 31. Since the width W1 of the central cover 31 is longer than the width HW of the patient's head, the central cover 31 can be deformed so as to wrap the patient's head, which is preferable for infection prevention. The width HW of the patient's head is generally about 160 mm. The width W1 of the central cover 31 is not particularly limited, but is preferably 300 to 500 mm, more preferably 350 to 400 mm.

The width W2 of the two side covers 32 is not particularly limited, but is, for example, 200 mm.

The horizontal separation distance W3 of the two side covers 32 is preferably a length larger than that of the patient's head, for example, 160 mm or more, and 200 mm as an example.

The horizontal width W4 of the portion of the two side covers 32 that does not overlap with the central cover 31 is not particularly limited, but is, for example, 100 mm.

The width P of each overlapping portion 33 (the direction perpendicular to the thickness direction of the side cover 32 and the direction X in which the side cover 32 hangs down (for example, the downward direction) and the direction perpendicular to the direction (for example, the horizontal length)) is Although not particularly limited, it is preferably 80 to 100 mm. As an example, the width P is 100 mm.

The total width W of the cover 30 including the central cover 31 and the two side covers 32 is not particularly limited, but is, for example, 600 mm.

The height H1 of the upper ends of the central cover 31 and the side covers 32 in the vertical direction from the floor surface is not particularly limited, but is higher than the head of the practitioner sitting on the chair 50 so as to surely suppress the infection. Is preferable, and it is preferably 1200 to 1300 mm.

The height H2 (see FIG. 1) of the lower ends of the central cover 31 and the side covers 32 in the vertical direction from the floor surface is not particularly limited, but is preferably less than the height of the bed 40 on which the patient lies. The height of the bed 40 on which the patient lies is usually about 400 to 650 mm. Therefore, the height H2 of the central cover 31 and the side cover 32 is not particularly limited, but is preferably more than 0 mm and 300 mm or less.

In the present embodiment, the central cover 31 and the side cover 32 are rectangular having long sides along the hanging direction, but may be rectangular having short sides along the hanging direction. It may be square. Further, the shapes of the central cover 31 and the side covers 32 do not have to be quadrangular.

The constituent materials of the central cover 31 and the side cover 32 are not particularly limited as long as they are transparent and can be bent, and examples thereof include resin materials such as polyvinyl chloride, polyethylene, and polypropylene.

Next, a method of using the infection prevention device 10 according to the first embodiment will be described.

When using the infection control device 10, the patient is lying on the bed 40 and the practitioner is sitting on the chair 50, as shown in FIGS. 4 and 5. In this state, the practitioner's face and the patient's face are separated by the central cover 31 and the side cover 32, so that infection with each other can be prevented.

When performing the treatment on the patient's head, neck, shoulders, etc., the practitioner passes both arms toward the patient through the gap between the central cover 31 and the side covers 32, as shown in FIGS. 4 to 7. , Bring the face closer to the patient's head to see the area to be treated. At this time, the adjacent portions of the side cover 32 and the center cover 31 are deformed so as to bend toward the patient. Since the side cover 32 overlaps the patient side with respect to the central cover 31 at the overlapping portion 33, the side cover 32 can be bent more toward the patient side than the central cover 31 with almost no interference with the center cover 31. Therefore, a wide passage is secured between the side cover 32 and the center cover 31. Therefore, the surgeon can touch the affected part of the patient by passing only the tip from the vicinity of the wrist through between the side cover 32 and the central cover 31 toward the patient side. Therefore, the practitioner can perform the treatment without being hindered by the side cover 32 and the central cover 31. Further, since the side cover 32 is fixed to the support column 22 and the weight 32A is provided, the side cover 32 does not bend too much. Therefore, the side cover 32 plays a role of preventing infection and easily returns to the original state when the practitioner pulls out the arm.

Since the central cover 31 is less likely to be interfered with by the side cover 32 that flexes greatly, it does not bend more than necessary. The central cover 31 then bends to wrap the patient's head in an appropriate shape, as shown in FIGS. 6 and 7. Therefore, the central cover 31 can maintain a good isolation between the practitioner's face and the patient's face and prevent infection with each other.

As described above, the infection control device 10 according to the first embodiment is the infection control device 10 used in the treatment, and is a transparent center that is supported by the support portion 23 and the support portion 23 and hangs down from the support portion 23. It is supported by the cover 31 and the support portion 23 and hangs down from the support portion 23, and is perpendicular to the thickness direction of the central cover 31 and perpendicular to the hanging direction X of the central cover 31. It has two side covers 32, which are arranged on both sides of the direction.

By using the infection control device 10 configured as described above, the operator can separate the operator's face and the patient's face by the central cover 31 and the side cover 32, while the central cover 31 and the side cover 32 are separated from each other. The patient can be treated without disturbing the movement of the arm through the arm from between. Therefore, the infection control device 10 enables good treatment while effectively preventing infection between the practitioner and the patient.

Further, the two side covers 32 have an overlapping portion 33 that overlaps the central cover 31, and the overlapping portions 33 provided on the two side covers 32 are arranged on the same surface side with respect to the central cover 31. As a result, the infection prevention device 10 is provided with the overlapping portion 33, so that the function of suppressing the movement of the virus from the gap between the side cover 32 and the central cover 31 and isolating it to prevent infection can be enhanced. .. Further, the operator passes the arm between the central cover 31 and the side cover 32 from the side opposite to the side where the overlapping portion 33 overlaps the central cover 31, so that the central cover 31 wraps the patient's head in the center. While deforming the cover 31, the side cover 32 can be bent and the arm can be passed through. Therefore, the infection control device 10 is good without bending the side cover 32 and hindering the movement of the practitioner's arm while effectively preventing infection between the practitioner and the patient by the central cover 31. Allows treatment.

Further, the infection control device 10 has a support column 22 (side support portion) on which the opposite side of the side cover 32 adjacent to the central cover 31 is fixed. As a result, the position of the side cover 32 can be held at an appropriate position for infection prevention. The side support portion to which the side cover 32 is fixed may be formed at a place other than the support column 22.

<Second Embodiment>
As shown in FIGS. 8 and 9, the infection prevention device 60 according to the second embodiment includes a support 70 arranged on a floor surface or the like, and a cover 80 connected to the support 70.

The support 70 includes one support base 71 arranged so as to be in contact with the floor surface, one columnar column 72 extending substantially vertically upward from the support base 71, and a cover support to which the cover 80 is fixed. It has a portion 73 and a rotation holding portion 74 that rotatably holds the cover support portion 73 with respect to the support column 72.

The form of the support base 71 is not particularly limited as long as it can be stably arranged on the floor surface. The support column 72 is a member having the same shape extending substantially vertically upward from the support base 71. The direction in which the support column 72 extends from the support base 71 is not necessarily limited to the vertically upward direction, and may be inclined with respect to the vertical upward direction.

One end of the cover support portion 73 is fixed to the cover 80, and one end thereof is fixed to the rotation holding portion 74. The rotation holding portion 74 has a function of rotating the cover support portion 73 with respect to the support column 72, and has a structure capable of fixing the cover support portion 73 to the support column 72 at an arbitrary angle. The rotation holding portion 74 has, for example, a rotation shaft on which the support column 72 and the cover support portion 73 are pivotally attached, and is contacted and held by a frictional force that does not rotate unless a force equal to or higher than a predetermined force is applied. Alternatively, the rotation holding portion 74 may have a rotation shaft on which the support column 72 and the cover support portion 73 are pivotally attached, and may have a structure capable of screwing and fastening a bolt at an arbitrary rotation angle to fix the bolt. A known structure can be arbitrarily applied to the rotation holding unit 74.

The cover 80 is transparent so that the practitioner can see the patient and perform the treatment, and is a member for preventing droplets between the practitioner and the patient. The cover 80 is hard enough to maintain its shape. The cover 80 includes a curved portion 81 curved in an arc shape and two flat plate portions 82 sandwiching the curved portion 81.

The curved portion 81 is formed in an arc shape so as to draw a substantially semicircle in a cross section orthogonal to the direction Y extending from the side where the cover support portion 73 is fixed to the opposite side. The two flat plate portions 82 are flat plate-shaped portions continuous on both end sides of the arc of the curved portion 81. The flat plate portion 82 may be a perfect flat plate having an infinite radius of curvature, but may be a slightly curved flat plate having a radius of curvature larger than that of the curved portion 81. The two flat plate portions 82 are formed in parallel so as to be located on the same plane. The two flat plate portions 82 do not have to be located on the same plane, and may be formed so as to have an angle instead of being parallel. The curved portion 81 and the flat plate portion 82 are preferably formed integrally, but may be separate members.

The constituent material of the cover 80 is not particularly limited as long as it is transparent and hard to some extent, and examples thereof include resin materials such as acrylic resin, polyvinyl chloride (particularly hard polyvinyl chloride), polyethylene, polypropylene, and glass. Be done.

Next, a method of using the infection prevention device 60 according to the second embodiment will be described.

When using the infection control device 60, the patient is lying on the bed 40 and the practitioner is sitting on the chair 50. In this state, as shown in FIG. 10, the rotation holding portion 74 can be operated to cover the patient's head at an arbitrary angle by the curved portion 81 of the cover 80. At this time, the two flat plate portions 82 may be arranged with a predetermined gap S from the upper surface of the bed 40. The gap is not particularly limited, but is preferably a size that allows the practitioner to perform the treatment through the arm, for example, 150 to 400 mm. By putting a hand between the cover 80 and the bed 40, the practitioner can perform the treatment while visually observing the part to be treated through the cover 80. The cover 80 can maintain a good isolation between the practitioner's face and the patient's face and prevent infection with each other. The flat plate portion 82 may come into contact with the upper surface of the bed 40. In this case, the face of the practitioner and the face of the patient can be more reliably separated from each other.

The cover 80 may not be provided with the flat plate portion 82 as in the modified example shown in FIG. In this case, the curved portion 81 may be brought into contact with the upper surface of the bed 40, but may be separated with a gap S without being brought into contact with the bed 40.

Further, as in the other modification shown in FIG. 12, the cover 80 may be formed by the flat plate portion 82 without the curved portion 81 provided. In this case, the cover 80 does not come into contact with the upper surface of the bed 40 and is separated with a gap.

As described above, the infection control device 60 according to the second embodiment is the infection control device 60 used in the treatment, and is a support base 71 that can be arranged on the floor surface and a support column 72 that extends from the support base 71. A cover support portion 73 that is rotatable with respect to the support column 72, a rotation holding portion 74 that rotatably holds the cover support portion 73 with respect to the support column 72, and a transparent cover 80 fixed to the cover support portion 73. , And the cover 80 is formed in an arc shape in a cross section orthogonal to the direction Y extending from the side where the cover support portion 73 is fixed to the opposite side.

The infection control device 60 configured as described above can rotate the cover 80 by using the rotation holding portion 74 and cover the patient's head at an appropriate position by the curved portion 81 of the cover 80. Therefore, the cover 80 separates the operator's face from the patient's face, and the space between the cover 80 and the bed 40 through which the arm passes can be made appropriate. Therefore, the infection control device 60 enables good treatment while effectively preventing infection between the practitioner and the patient.

Further, the cover 80 has a flat plate portion 82 continuous from both ends of the arc of the curved portion 81. As a result, the practitioner secures a space between the bed 40 and the flat plate portion 82 through which the practitioner can pass his / her arm to perform the treatment, and keeps the curved portion 81 and the flat plate portion 82 at an appropriate distance from the patient. Can be placed. Therefore, the infection control device 60 enables good treatment while effectively preventing infection between the practitioner and the patient.

The present invention is not limited to the above-described embodiment, and various modifications can be made by those skilled in the art within the technical idea of the present invention. For example, as in the modified example of the first embodiment shown in FIG. 13A, the edge portion other than the upper end of the central cover 31 (for example, the end portion of the lower end close to the support column 22) is the support column 22 (side). It may be connected to the support portion) by a flexible string-shaped connecting member 34. The connecting member 34 is a stretchable member made of, for example, natural rubber or synthetic rubber. Alternatively, although the connecting member 34 hardly expands and contracts, the support column 22 and the central cover 31 may be connected in a state where there is some looseness (deflection). By providing the connecting member 34, the central cover 31 is allowed to move to some extent, so that it does not interfere with the treatment and can be prevented from being rolled up. Therefore, good treatment is possible while effectively preventing infection between the practitioner and the patient.

Further, as in the other modification of the first embodiment shown in FIG. 13B, the support column 22 has a rotation holding portion 74 that is rotatable and can be fixed at an arbitrary angle as in the second embodiment. It may be provided.

Further, as in still another modification of the first embodiment shown in FIG. 14, the support 20 may have a top plate 25 fixed to the support portion 23 or the support column 22. The top plate 25 is located above at least a part of the cover 30 (the direction opposite to the direction X (downward) in which the cover 30 hangs down), and the support portion 23 or the support column 22 covers the upper part of the patient's head. Overhangs to the patient side. The top plate 25 extends toward the patient so as to be substantially parallel to the floor surface, but it does not have to be parallel to the floor surface. The angle of the top plate 25 with respect to the floor surface may be adjustable. The top plate 25 may or may not be transparent. If the top plate 25 is transparent, the practitioner can visually inspect the affected area through the top plate 25 and perform the treatment. As shown in FIG. 14B, the top plate 25 may be formed with an edge portion 26 in a direction orthogonal to the overhanging direction bent downward. Such an edge portion 26 may also be provided at an end portion of the top plate 25 in the overhanging direction. The edge 26 of the top plate 25 does not have to be bent.

The top plate 25 can prevent the droplets of the patient from diffusing from the ceiling direction to the entire room when the patient talks or coughs. That is, the top plate 25 can limit the range in which the droplets spread. By providing the edge portion 26 on the top plate 25, the effect of suppressing the diffusion of droplets can be further enhanced.

Further, as in still another modification of the first embodiment shown in FIG. 15, the support base 21 may have wheels 27 that can rotate in contact with the floor surface. This facilitates the movement of the infection control device 10. The wheel 27 can also be applied to the other embodiments described above.

Further, as shown in FIG. 16, the cover 80 of the infection prevention device 60 according to the second embodiment may be provided with the same central cover 31 and side covers 32 as those in the first embodiment. The cover 80 can function not only as a top plate but also as a support portion for fixing the central cover 31 and the side cover 32. If the cover 80 is transparent, the central cover 31 and the side covers 32 do not have to be transparent, but are preferably transparent. Further, if the central cover 31 and the side cover 32 are transparent, the cover 80 does not have to be transparent, but is preferably transparent. Further, in the modified example of the second embodiment shown in FIGS. 11 to 12, the same central cover 31 and side cover 32 as in the first embodiment may be provided.
