The embodiment is not limited to the invention but is an example. Not all features and combinations thereof described in the embodiments are essential to the invention.

An embodiment of a microscope dental care system, a microscope dental care drape device, and a method for manufacturing the same will be described with reference to FIGS. 1 to 9. As shown in FIG. 1, when the clinic table 1 (for example, a reclining dental examination chair) is set flat and the patient 2 is lying on it, the microscope 10 for dental practice is It is supported above the patient 2 by the support arm 15. That is, the microscope 10 has a substantially L-shaped lens barrel portion 11, and the objective lens portion 12 at the lower end of the lens barrel portion 11 is supported at a position where a predetermined portion of the oral cavity of the patient 2 can be observed. An eyepiece 13 is provided at the opposite end of the lens barrel 11 so that the operator can look into it.

The microscope dental drape device 20 for forming a treatment space S that separates the patient from the operator is a lens barrel portion 11 (a lens barrel portion 11) as a mounting portion of the microscope 10 in the mounting portion 40 at the upper end position thereof. It is suspended (mounted) on the base of the lens barrel on the objective lens side. Although the details will be described later, the drape device 20 has a transparent resin sheet 21 that covers from the head to the chest of the patient 2 lying on the medical table 1 and a frame 30 that supports the transparent resin sheet 21 that separates the patient from the operator. It forms a treatment space S (a bell-shaped space or a tubular space with a closed upper part), and functions so as not to diffuse the aerosol generated by the medical treatment to the periphery outside the treatment space. The eyepiece portion 13 of the microscope 10 is located outside the drape device 20, that is, outside the treatment space.

The exhaust system has a flexible exhaust pipe 25 having an outer diameter of 20 mm and an inner diameter of about 15 mm. The flexible exhaust pipe 25 is pulled into the clinic from outside the clinic, and is further inserted downward along the upper edge of the support arm 15 into the mounting portion 40 of the drape device 20. That is, the suction port of the flexible exhaust pipe 25 is open to the upper part of the treatment space S formed in the drape device 20. When the exhaust system is in operation, the flexible exhaust pipe 25 sucks in air containing an aerosol in the treatment space S and exhausts it to the outside (outside the clinic where the patient and the operator are). Exhaust gas may be filtered or sterilized as necessary.

The flexible exhaust pipe 25 of the exhaust system that exhausts the aerosol from the treatment space S is provided along the support arm 15 and the lens barrel portion 11 of the microscope 10. As shown in FIGS. 5A to 5C, the flexible exhaust pipe 25 is attached (bonded) to the side surface of the lens barrel portion 11 so that the suction port opens at the upper part of the treatment space S. ) With the stopper 26, it is held and positioned downward.

FIG. 2 is a perspective view of the microscope dental drape device 20 when it is not mounted on the microscope 10 and is in a suspended state (three-dimensional state) with the mounting portion 40 facing up, and FIG. 3 shows a frame configuration of the drape device 20. It is a perspective view which shows. As shown in these figures, the drape device 20 has a transparent resin sheet 21 and a frame 30 that supports the transparent resin sheet 21 so as to form a cylinder. The frame 30 has a gap between a tubular frame portion 31 for forming the treatment space S inside and a mounting portion 40 for detachably suspending (mounting) the tubular frame portion 31 on the lens barrel portion 11 of the microscope 10. It is a hanger type frame having a ring-shaped frame portion 41 (substantially C-shaped frame portion).

The tubular frame portion 31 has a plurality of connecting the upper ring-shaped frame portion 32, the lower ring-shaped frame portion 33 having a larger diameter, the upper ring-shaped frame portion 32, and the lower ring-shaped frame portion 33 (in the case of illustration). Has 5) first connecting frame portions 35. The upper ring-shaped frame portion 32 is for maintaining a predetermined tubular shape, and the lower ring-shaped frame portion 33 is used when the patient 2 is lying on the clinic table 1 as shown in FIG. It is desirable that the shape is such that it can surround the head to the chest, and is made of a flexible soft resin tube or the like for the convenience of the surgeon to insert his / her hand into the treatment space for medical treatment. Further, as shown in FIG. 2, recesses 33a and 33b curved toward the upper ring-shaped frame portion 32 are formed in the lower ring-shaped frame portion 33 in order to form a recess for the operator to insert a hand. There is. For example, the recess 33a is provided on the right side of the drape device 20 and the recess 33b is provided on the left side when viewed from the operator. For the upper ring-shaped frame portion 32, the lower ring-shaped frame portion 33, and the first connecting frame portion 35, for example, a thin resin tube can be used. In that case, a T-shaped joint 37 can be used for the connecting portion C between the upper ring-shaped frame portion 32 and the first connecting frame portion 35 in FIG. 3, as shown in FIG. 7 showing the manufacturing process, and the T-shaped joint can be used. The frame 30 can be easily turned inside out with 37 as a rotation fulcrum (the reason why the frame 30 needs to be turned inside out will be described later in the description of the manufacturing method). As shown in FIG. 4B, the upper ring-shaped frame portion 32 uses a core material 32b such as a stainless wire inside the resin tube 32a so as to be able to hold a desired shape such as a substantially circular shape. can. A T-shaped joint can also be used for the connecting portion between the lower ring-shaped frame portion 33 and the first connecting frame portion 35.

The mounting portion 40 has a ring-shaped frame portion 41 with a gap having a certain degree of elasticity (preferably having flexibility or flexibility), and the ring-shaped frame portion 41 with a gap has a gap as shown in FIG. 5 (C). Couplings 42A and 42B (for example, luer lock) as mutually removable engaging members are provided at both ends. The ring-shaped frame portion 41 with a gap is connected to the upper ring-shaped frame portion 32 by a plurality of (three in the figure) second connecting frame portions 43. The length of the ring-shaped frame portion 41 with a gap is a size suitable for the outer circumference of the lens barrel portion 11 which is a mounted portion of the microscope 10, that is, a size substantially matching the outer circumference of the lens barrel portion 11. A thin resin tube can also be used for the frame portions 41 and 43. A T-shaped joint can also be used for the connecting portion between the upper ring-shaped frame portion 32 and the ring-shaped frame portion 41 with a gap and the second connecting frame portion 43.

The transparent resin sheet 21 held in a cylindrical shape whose upper side is squeezed by the frame 30 is a thin and soft material, and has a cylindrical shape suitable for the outer diameter of the tubular frame portion 31 (for example, the bottom of the garbage bag is cut open). A flat transparent resin sheet may be rolled into a cylinder and formed into a cylinder with a tape or an adhesive.

The procedure for attaching the transparent resin sheet 21 to the frame 30 will be described below with reference to FIGS. 6 to 9 showing the manufacturing method of the drape device 20.

FIG. 6 is a perspective view showing the frame hanging jig 50 used in the manufacture of the drape device 20, and is a peripheral view of the lens barrel portion 11 (the base portion of the lens barrel portion on the objective lens portion side) as the mounted portion of the microscope 10. A tubular or columnar member 51 having a size suitable for the length (specifically, a peripheral length substantially the same as the peripheral length of the lens barrel), an outer ring portion 52 having the tubular or columnar member 51 inside, and a predetermined height. It also has a plurality of (suspended) holding parts 53 provided on the outer ring portion 52 suspended or held. The case shown in the figure is an example of modifying the clothesline, in which the adhesive tape 57 is held by the sandwiching part 56 provided in the inner ring portion 55 concentrically with the outer ring portion 52 and the lower end portion of the adhesive tape 57. Is adhered to the upper part of the outer peripheral surface of the tubular or columnar member 51. As a result, the tubular or columnar member 51 is suspended from the inner ring portion 55 so as to be below the outer ring portion 52 and substantially concentric with the outer ring portion 52. As a dedicated jig, a tubular or columnar member 51 may be integrally provided concentrically with the outer ring portion 52. The lower portion 51a of the tubular or columnar member 51 has a large diameter in order to prevent the frame 30 from falling off when the frame 30 is attached.

As described above, the frame 30 has a cylindrical frame portion 31 having an upper ring-shaped frame portion 32 and a lower ring-shaped frame portion 33, and a ring-shaped frame portion 41 with a gap inside the upper ring-shaped frame portion 32. Further, it has a first connecting frame portion 35 and a second connecting frame portion 43. Before providing the transparent resin sheet 21 on such a frame 30, first, as shown in FIG. 7, the mounting portion 40 on the upper part of the frame 30 is mounted on the outer periphery of the cylindrical or columnar member 51, but the frame 30 is preliminarily mounted. It is attached to the tubular or columnar member 51 as a state turned inside out from the original state. That is, after turning over the frame 30, the ring-shaped frame portion 41 with a gap is wound around the outer peripheral portion of the tubular or columnar member 51, and the couplings 42A and 42B at both ends of the ring-shaped frame portion 41 with a gap (shown in FIG. 2 and the like). To concatenate. As a result, the upper portion of the frame 30 in the inverted state is attached to the cylindrical or columnar member 51 and is suspended from the cylindrical or columnar member 51. The frame 30 uses a T-shaped joint 37 for the connecting portion C between the upper ring-shaped frame portion 32 and the first connecting frame portion 35, and the T-shaped joint 37 is shown in FIGS. 4 (B) and 9 (A). Since it is connected to the resin tube 32a of the upper ring-shaped frame portion 32 but not to the inner core material 32b, it can be easily twisted in the rotation direction. That is, the frame 30 has a structure that can be turned inside out.

Next, as shown in FIG. 8, the transparent resin sheet 21 is put on the outside of the frame 30 (the frame 30 turned inside out is put inside the transparent resin sheet 21), and the upper edge of the transparent resin sheet 21 is hung from the frame. Each of the 50 plurality of sandwiching parts 53 is sandwiched. As a result, the transparent resin sheet 21 and the inverted frame 30 are suspended by the frame suspending jig 50. Then, as shown in FIG. 9A, the transparent resin sheets 21 are sandwiched between the transparent resin sheets 21 so as to surround the upper ring-shaped frame portion 32 and heat-welded (for example, a commercially available sealer is used).

After that, the ring-shaped frame portion 41 with a gap is temporarily removed from the tubular or columnar member 51, an extra portion at the upper part of the transparent resin sheet 21 is inserted inside the ring-shaped frame portion 41 with a gap, and the frame 30 is in an inverted state. Is turned over to return to the original state (the frame 30 is positioned on the outside of the transparent resin sheet 21), and the ring-shaped frame portion 41 with a gap is wound around the outer peripheral portion of the tubular or columnar member 51 again to form the ring-shaped frame portion 41 with a gap. The couplings 42A and 42B (shown in FIG. 2 and the like) at both ends of the above are connected. At this time, the transparent resin sheet 21 is interposed between the outer peripheral portion of the tubular or columnar member 51 and the ring-shaped frame portion 41 with a gap. After that, as shown in FIG. 2, the length of the transparent resin sheet 21 extending downward from the lower ring-shaped frame portion 33 is adjusted to an appropriate dimension. At this time, the notch 21a of the transparent resin sheet 21 is formed in the portion corresponding to the recess 33a of the lower ring-shaped frame portion 33, and the operator's right hand is put into the treatment space S. A notch 21b is formed in the portion corresponding to the recess 33b, and the assistant's hand is to be put into the treatment space S. Further, a notch 21c of the transparent resin sheet 21 is formed at an intermediate position between the notches 21a and 21b, and the operator's left hand is put into the treatment space S. After adjusting the length of the transparent resin sheet 21, the transparent resin sheets 21 are sandwiched between the transparent resin sheets 21 and heat-welded so as to surround the lower ring-shaped frame portion 33 with the transparent resin sheet 21 as shown in FIG. 9B. By finally attaching the transparent resin sheet 21 to the lower ring-shaped frame portion 33, wrinkles are less likely to occur on the transparent resin sheet 21. It should be noted that the attachment operation between the first connecting frame portion 35 and the second connecting frame portion 43 and the transparent resin sheet 21 is unnecessary. Further, it is not necessary to attach the transparent resin sheet 21 to the connecting portion between the upper ring-shaped frame portion 32 and the first connecting frame portion 35 and the second connecting frame portion 43, and similarly to the lower ring-shaped frame portion 33. It is not necessary to attach the transparent resin sheet 21 to the connecting portion with the first connecting frame portion 35.

After that, the frame 30 provided with the transparent resin sheet 21 is removed from the frame hanging jig 50 (the couplings 42A and 42B at both ends of the ring-shaped frame portion 41 with a gap are removed). As a result, the drape device 20 is obtained in which the frame 30 is attached to the outside of the transparent resin sheet 21 and the cutouts 21a, 21b, 21c are formed at appropriate positions in the lower portion of the transparent resin sheet 21.

In the completed drape device 20, the upper portion of the transparent resin sheet 21 is narrowed down from the outside by the ring-shaped frame portion 41 with a gap as shown in FIG. 4 (A), and the upper ring-shaped frame portion 32 is narrowed down as shown in FIG. 4 (B). The transparent resin sheets 21 were heat-welded to each other so as to be surrounded by the transparent resin sheet 21, and the transparent resin sheets 21 were heat-welded to each other so as to surround the lower ring-shaped frame portion 33 with the transparent resin sheet 21 as shown in FIG. It becomes a composition. That is, the structure is such that the frame 30 is not exposed to the treatment space S formed inside the drape device 20.

The microscope 10 of the drape device 20 is attached to the lens barrel portion 11 (attached portion) of the lens barrel portion 11 and the flexible exhaust as shown in FIGS. 5A to 5C (not shown in the transparent resin sheet 21). A ring-shaped frame portion 41 with a gap is provided so as to surround the tube 25, and the couplings 42A and 42B are coupled in a stretched state by utilizing the elasticity of the ring-shaped frame portion 41 with a gap. As a result, the lens barrel portion 11 and the flexible exhaust pipe 25 are tightened and held by the force of the ring-shaped frame portion 41 with a gap in the contraction direction. Further, the ring-shaped frame portion 41 with a gap is held by the stopper 27 attached (adhered) to the side surface of the lens barrel portion 11 in order to prevent the ring-shaped frame portion 41 with a gap from falling. As a result, the transparent resin sheet 21 located inside the ring-shaped frame portion 41 with a gap is tightened and held around the lens barrel portion 11 and the flexible exhaust pipe 25 in a folded state, and the drape device 20 is attached. There is almost no gap between the portion 40, the lens barrel portion 11, and the flexible exhaust pipe 25.

In the configuration of the above embodiment, the drape device 20 of FIG. 1 is covered with the lens barrel portion 11 of the microscope 10 so as to cover the patient 2 lying on the clinic table 1 from the head to the chest before dental treatment. It is attached to the attachment portion {FIGS. 5 (A) to (C)}. As a result, a bell-shaped or tubular treatment space S with a closed upper portion is formed inside the transparent resin sheet 21 of the drape device 20. At this time, the treatment space S is set so that the patient 2 and the operator are separated from each other, and the objective lens portion 12 of the microscope 10 is located inside the treatment space S and the eyepiece portion 13 is located outside.

The aerosol generated by the dental treatment using the microscope 10 is confined inside the drape device 20 to prevent diffusion to the outside of the treatment space. At the same time, the exhaust system is operated during and for a while after the medical treatment, and the air including the aerosol in the treatment space S inside the drape device 20 is discharged from the suction port of the flexible exhaust pipe 25 of the exhaust system to the upper part of the treatment space S. It sucks from and exhausts to the outside of the clinic. This ensures that the aerosol in the clinic is prevented from scattering and that the aerosol in the drape device 20 does not scatter into the clinic when the drape device 20 is replaced for the next patient.

According to this embodiment, the following effects can be obtained.

(1) The drape device 20 forms a treatment space S that separates the patient 2 from the operator, and the air containing the aerosol in the treatment space can be exhausted to the outside of the clinic through the flexible exhaust pipe 25. As a result, it is possible to prevent the aerosol from diffusing to the operator side during medical treatment, and since the aerosol does not remain inside the drape device 20, the aerosol does not scatter when the drape device 20 is replaced.

(2) The drape device 20 has a transparent resin sheet 21 and a frame 30 that supports the transparent resin sheet 21, and the frame 30 has a cylindrical frame portion 31 having upper and lower ring-shaped frame portions 32 and 33, and a tubular shape. It has a mounting portion 40 for mounting the frame portion 31 on the microscope 10, and can always realize a treatment space S having a stable shape and size.

(3) The mounting portion 40 of the drape device 20 has a ring-shaped frame portion 41 with an elastic gap having couplings 42A and 42B detachable from each other at both ends, and the length of the ring-shaped frame portion 41 with a gap. Since the size is set to match the peripheral length of the mounted portion of the microscope 10, the drape device 20 can be easily attached to and detached from the microscope 10 (there is no need to use an adhesive tape or the like). Further, when the drape device 20 is attached to the microscope 10, it is possible to form a bell-shaped or cylindrical treatment space S with a closed upper portion inside the transparent resin sheet 21. By using couplings 42A and 42B that can be attached and detached with one touch, such as a luer lock, the drape device 20 can be attached and detached with one touch, and the elasticity of the ring-shaped frame portion 41 with a gap is used. Since the transparent resin sheet 21 can be surrounded and attached to the mounted portion of the microscope 10 in a tightened state, leakage of aerosol from the upper part of the drape device 20 can be prevented.

(4) Since the lower ring-shaped frame portion 33 of the tubular frame portion 31 has recesses 33a and 33b recessed toward the upper ring-shaped frame portion 32, the transparent resin sheet at the position corresponding to the recesses 33a and 33b. By using the notches 21a and 21b of 21 and the additionally formed notches 21c, it becomes easy for the surgeon and the assistant to put in and take out the arm. The lower portion of the other tubular frame portion 31 is set so that the distance between the upper ring-shaped frame portion 32 and the lower ring-shaped frame portion 33 is sufficiently long to sufficiently cover the head and chest of the patient 2. Further, the transparent resin sheet 21 extends below the lower ring-shaped frame portion 33 to prevent the aerosol from leaking out.

(5) Since the drape device 20 has a structure in which the frame 30 is located outside the transparent resin sheet 21 (a structure in which the frame 30 is not exposed to the treatment space S), the frame 30 is less likely to be contaminated with aerosol. Therefore, the frame 30 can be used repeatedly by replacing the transparent resin sheet 21, and the work of disinfecting, sterilizing, and removing the virus of the frame 30 becomes easy.

FIG. 10 is a perspective view showing another embodiment of the microscope dental drape device according to the present invention, in which the first connecting frame portion 35 is separable at the intermediate portion. In this case, mutually removable couplings 39A and 39B (for example, luer lock) are provided at the intermediate position of the first connecting frame portion 35 that connects the upper ring-shaped frame portion 32 and the lower ring-shaped frame portion 33. Has been done. Other frame configurations are the same as in FIG.

Since the first connecting frame portion 35 can be separated at the intermediate position by the couplings 39A and 39B, the frame 30 can be stored in a separated state at the intermediate position of the first connecting frame portion 35, and can be stored in a state where it is easy to stack. , It is possible to reduce the storage space. Further, the lower side of the first connecting frame portion 35 and the lower ring-shaped frame portion 33, which are likely to be contaminated with aerosol, can be more carefully disinfected, sterilized, and virus-removed.

Although the present invention has been described above by taking the embodiment as an example, it is understood by those skilled in the art that various modifications can be made to each component and each processing process of the embodiment within the scope of the claims. By the way. Hereinafter, a modification example will be touched upon.

In the embodiment, the ring-shaped frame portion 41 with a gap is provided as the mounting portion 40 provided at the upper end portion of the frame 30, but this is omitted and the adhesive tape (adhesive tape) that can be easily peeled off is provided at the upper end edge portion of the transparent resin sheet 21.
