Description

[Technical Field]

[0001] The present disclosure relates to a patient isolation device for infection control, and more particularly to a patient isolation device used when providing treatment to a patient. [Background technology]

[0002] For example, Patent Document 1 (JP 2010-264076 A) discloses an isolation device for isolating patients with infectious diseases, etc. from other spaces. This isolation device uses a curtain to cover a wide area of ​​a hospital room, including the bed used by the patient. Medical staff enter the curtain to provide the necessary treatment to the patient. The curtain has a height that extends from near the ceiling of the hospital room to the floor. The curtain has an entrance on the side, and patients and medical staff enter and exit the interior of the curtain through this entrance.

[0003] Medical personnel entering the enclosure must wear infection control equipment. Medical personnel entering the enclosure must focus solely on treating infected patients within the enclosure, making it difficult for them to treat other patients. Thus, conventional isolation devices significantly reduce the work efficiency of medical personnel. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2010-264076 Summary of the Invention [Problem to be solved by the invention]

[0005] It is desirable to use an isolation device to protect patients from infectious diseases or to protect medical personnel from patients with infectious diseases. For example, since patients undergoing treatment are generally more likely to develop serious infections if they contract an infectious disease, it is preferable to isolate the patient in situations where there is a risk of infection. Also, even if a patient undergoing treatment contracts another infectious disease, it is necessary to continue treatment, and in such cases it is preferable to isolate medical personnel from the patient.

[0006] For example, assuming that the isolation device described in Patent Document 1 is used to treat a patient with a treatment device, both the patient and the treatment device will be covered by the isolation device's curtain. This is because the patient and the treatment device may be connected by tubes or other components of a blood circuit, and cannot be placed far apart, so the treatment device will be placed near the bed inside the isolation device. Furthermore, medical personnel may operate the treatment device at the start of or during treatment, in which case they will need to enter the isolation device's curtain. Furthermore, medical personnel may perform procedures such as punctures on the patient, in which case they will also need to enter the isolation device's curtain.

[0007] When using conventional isolation devices, the treatment equipment is located inside the isolation device, so if the patient is infected with an infectious disease, the treatment equipment may be contaminated. Also, since the patient and medical staff enter the isolation device at the same time, conventional isolation devices cannot separate the patient and medical staff.

[0008] Therefore, the present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a patient isolation device that can isolate a treatment device and medical staff from a patient. [Means for solving the problem]

[0009] According to the present invention, a patient isolation device includes a curtain that covers at least the upper and lateral sides of a patient through a space, and a support that supports the curtain. The curtain separates the patient from a treatment device for providing treatment to the patient.

[0010] In the patient isolation device, the area of ​​the curtain in a plan view may be similar to the area of ​​a bed used by the patient in a plan view.

[0011] The patient isolation device may be attached to or placed on a bed used by the patient.

[0012] In the patient isolation device, the curtain has a curtain body having an opening through which the patient can enter and exit, and a flap for closing the opening in an openable and closable manner, and the upper end of the flap is continuous with the curtain body, and its both sides and lower part may be detachable from the curtain body.

[0013] In the patient isolation device, the upper end of the flap may be positioned above the patient.

[0014] In the patient isolation device, the support has a plurality of support posts, and the plurality of support posts include a flap support post that overlaps at least a portion of the opening and supports the flap, and at least the portion of the flap support post that overlaps with the opening may be removable.

[0015] The patient isolation device may further include a suction device connected to the curtain to create a negative pressure inside the curtain, and a sterilization device to sterilize the air sucked by the suction device.

[0016] In the patient isolation device, the curtain may be provided with a valve that opens when the inside of the curtain is under negative pressure, allowing the inside of the curtain to communicate with the outside. [Effects of the Invention]

[0017] The patient isolation device according to the present disclosure can isolate the treatment device from the patient, and can also isolate the medical personnel operating the treatment device from the patient. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0019] Hereinafter, the structure of a patient isolation device according to an embodiment of the present disclosure will be described with reference to the drawings.

[0020] FIG. 1 is a plan view schematically illustrating a state in which treatment is performed using an isolation device according to an embodiment. Examples of treatment devices according to this embodiment include a hemodialysis device, a blood filtration device, a blood diafiltration device, and a blood purification device. With reference to FIG. 1, an example of a state in which the isolation device 100 according to this embodiment is used will be described. In the following description of the embodiment, the treatment device will be a dialysis device, but the treatment device is not limited to a dialysis device.

[0021] The isolation device 100 is placed on a bed 10 used by a patient 1. A dialysis machine 20 serving as a treatment device is installed beside the bed 10. The curtain of the isolation device 100 is positioned between the dialysis machine 20 and the patient 1. The curtain of the isolation device 100 separates the patient 1 from the dialysis machine 20 when dialysis is performed on the patient 1 using the dialysis machine 20. When treatment is being performed, the dialysis machine 20 and the patient 1 are connected by a tube 30 that forms a blood circuit. The tube 30 passes through an opening in the curtain.

[0022] 1, the area of ​​the isolation device 100 in a plan view is similar to the area of ​​the bed 10 in a plan view. The area of ​​the isolation device 100 in this embodiment in a plan view is slightly smaller than the area of ​​the bed 10 in a plan view. The area of ​​the isolation device 100 in a plan view may be the same as the area of ​​the bed 10 in a plan view, or may be slightly larger.

[0023] In this embodiment, the isolation device 100 is placed on the bed 10. Here, "placed" includes not only the case where the isolation device 100 is placed on the mattress 12 of the bed 10, but also the case where the isolation device 100 is placed on the frame 14 of the bed 10 with a part of the isolation device 100 sandwiched between the mattress 12 and the frame 14.

[0024] The isolation device 100 is connected to a suction device 500 that creates a negative pressure inside and removes viruses and the like. The suction device 500 has a fan for creating negative pressure. Inside the suction device 500, a sterilization device consisting of an ultraviolet irradiation device and / or a HEPA filter is provided, and it can remove viruses and the like and exhaust the air. The suction device 500 and the sterilization device may be separate entities.

[0025] The sterilization device may be equipped with both an ultraviolet irradiation device and a HEPA filter, or only one of them. The suction device 500 creates negative pressure inside the isolation device 100 to prevent viruses and the like from spreading outside the isolation device 100.

[0026] The suction device 500 preferably maintains the inside of the isolation device 100 at a pressure at least 2.5 Pa lower than the outside air pressure. The capacity of the suction device 500 is preferably such that the air inside the isolation device 100 is replaced at least 12 times per hour. The air volume of the suction device 500 is preferably 30 L / h or more. The air volume of the suction device 500 is preferably variable. For example, the air volume of the suction device 500 is preferably three times or more in the shunt mode described below compared to the normal mode.

[0027] As an example of a sterilization device, Fig. 14 shows an ultraviolet irradiation device 550. The ultraviolet irradiation device 550 has a cylindrical shielding wall 552 and a rod-shaped ultraviolet lamp 554. The shielding wall 552 prevents ultraviolet rays emitted from the ultraviolet lamp 554 from escaping to the outside.

[0028] Shielding wall 552 is hollow, and the hollow portion forms air flow path 556. Air inside isolation device 100 is guided through air flow path 556 in the direction shown by the arrow in Figure 14. Ultraviolet lamp 554 extends along the central axis of air flow path 556. Ultraviolet light emitted from ultraviolet lamp 554 is irradiated onto air passing through air flow path 556, thereby sterilizing the air.

[0029] The ultraviolet irradiation capacity of the ultraviolet lamp 554 is 3 mJ / m2 It is preferable that the ultraviolet lamp 554 is 3 mJ / m or more. 2 By having the above ultraviolet irradiation capability, it is possible to more reliably sterilize the air. The structure of the ultraviolet irradiation device 550 is an example, and the ultraviolet irradiation device 550 may have a different structure.

[0030] Fig. 2 is a perspective view showing the isolation device placed on a bed. The structure of the isolation device 100 of this embodiment will be described with reference to Fig. 2. The isolation device 100 of this embodiment includes a curtain 200 that covers at least the upper and sides of the patient via a space, and a support 300 that supports the curtain 200.

[0031] The support body 300 includes end supports 310 located at both longitudinal ends of the curtain body 200, a middle support body 330 located approximately in the longitudinal center of the curtain body 200, and a ceiling support body 320 extending longitudinally from the ceiling portion of the curtain body 200. Here, the longitudinal direction means the direction of the long side when the bed 10 is viewed from above.

[0032] The end supports 310 and the intermediate supports 330 are each configured in an arch shape. In other words, the end supports 310 and the intermediate supports 330 are configured in a roughly inverted U shape. Both the end supports 310 and the intermediate supports 330 are configured as poles that are flexible in the bending direction. The end supports 310 and the intermediate supports 330 are linear in the relaxed state. Examples of poles that are flexible in the bending direction include poles made of resin materials reinforced with glass fiber or carbon fiber, and poles made of lightweight metals such as aluminum that are relatively easily deformed. The end supports 310 and the intermediate supports 330 may be formed from members that maintain a roughly inverted U shape even in the relaxed state. The end supports 310 and the intermediate supports 330 are not limited to structures with an arch shape, and may also be structures in which the upper ends of a pair of vertically extending pillar members are connected by a horizontally extending beam member. In other words, the end supports 310 and the intermediate supports 330 may be gate-shaped structures. The end support 310 and the intermediate support 330 may be configured as two linear members connected at an angle at their upper ends. In other words, the end support 310 and the intermediate support 330 may be configured as a mountain-shaped structure.

[0033] The ceiling support 320 is also made of a pole made of the same material as the end support 310 and the intermediate support 330. The ceiling support 320 extends linearly in the longitudinal direction, connecting one end support 310 to the other end support 310. The ceiling support 320 extends in a direction that intersects with the intermediate support 330 at the ceiling.

[0034] The ceiling support 320 is connected to the end supports 310 and the middle supports 330. However, the ceiling support 320 may not be directly connected to the end supports 310 and the middle supports 330, but may be fixed to them via the curtain body 200. Specifically, the curtain body 200 may be provided with a pocket into which the end of the ceiling support 320 is inserted, thereby fixing the ceiling support 320 to the curtain body 200.

[0035] The intermediate support 330 includes a first member 332 and a second member 334. The first member 332 and the second member 334 are connected at the ceiling. The first member 332 is located on the side overlapping with the first opening 214a. The second member 334 is located on the side overlapping with the second opening 214b. The first member 332 and the second member 334 are connected by a connecting pipe 336. Specifically, the connecting pipe 336 is fixed to the ceiling-side end of the second member 334. The ceiling-side end of the first member 332 is inserted into the opening of the connecting pipe 336. Instead of a connection structure using the connecting pipe 336, the ceiling-side ends of the first member 332 and the second member 334 may be inserted into pockets provided on the ceiling side of the curtain 200, and the first member 332 and the second member 334 may be indirectly fixed via the curtain 200. Like the intermediate support 330, the end support 310 may also have a structure in which two members, a first member and a second member, are connected together.

[0036] The floor side ends of the first member 332 and the second member 334 of the intermediate support member 330 are inserted into a pocket 260 provided in the curtain body 200. The connecting pipe 336 of the intermediate support member 330 is fixed to the inner side of the curtain body 200 using a hook-and-loop fastener or the like (not shown).

[0037] The first member 332 of the intermediate support body 330 can be removed. When removing the first member 332, the ceiling side end of the first member 332 is pulled out from the connecting pipe 336, and the floor side end of the first member 332 is pulled out from the pocket 260. The second member 334 of the intermediate support body 330 can also be removed. When removing the second member 334, if the connecting pipe 336 of the second member 334 is connected to the first member 332, the ceiling side end of the first member 332 is pulled out from the connecting pipe 336. Next, the floor side end of the second member 334 is pulled out from the pocket 260.

[0038] The curtain 200 includes an upper curtain 210 and a bed curtain 250. The upper curtain 210 covers the patient from above and to the sides. The bed curtain 250 covers the patient from below. The bed curtain 250 may be omitted. Instead of the bed curtain 250, a belt or the like may be attached to maintain (restrain) the distance between the two bed-side ends of the intermediate support 330. The belt connects the pockets 260 on one side to the pockets 260 on the other side. In this embodiment, the bed curtain 250 is sandwiched between the mattress 12 and the frame 14 of the bed 10. The isolation device 100 including the curtain 200 is placed on the bed 10. The isolation device 100 may be attached to the bed 10 by fixing the support 300 to the frame 14 of the bed 10.

[0039] The upper curtain 210 includes end sheets 212 located at the longitudinal ends, and a main sheet 214 located laterally and above the patient lying inside. The main sheet 214 and end sheets 212 form the curtain body. The end sheets 212 and main sheet 214 are made of transparent sheets. The end sheet 212 has a roughly inverted U-shaped or semicircular outer shape. The end sheet 212 and main sheet 214 are connected by sewing along the contour of the end sheet 212.

[0040] A sleeve 216 is provided along the connection portion between the end sheet 212 and the main body sheet 214. The sleeve 216 is a cylindrical sheet provided along the contour of the end sheet 212. The sleeve 216 has a substantially inverted U-shape when viewed in the longitudinal direction. An end support 310 is inserted into the sleeve 216. By being inserted into the sleeve 216, the end support 310 takes on the same inverted U-shape as the sleeve 216. The longitudinal end of the upper curtain body 210 is supported by the end support 310, through which the sleeve 216 is inserted.

[0041] The main body sheet 214 has a first opening 214a and a second opening 214b through which a patient can enter and exit. The first opening 214a is provided on one side of the isolation device 100. The second opening 214b is provided on the other side of the isolation device 100. By providing the first opening 214a and the second opening 214b on each side, a patient can enter and exit from either side. It is also possible to omit either the first opening 214a or the second opening 214b.

[0042] The upper curtain body 210 has flaps 220 for releasably closing the first opening 214a and the second opening 214b. The flaps 220 are provided at the first opening 214a and the second opening 214b, respectively.

[0043] The upper end of the flap 220 is continuous with the main sheet 214. In this embodiment, the flap 220 and the main sheet 214 are formed from a single continuous sheet. The flap 220 and the main sheet 214 may be formed from separate sheets, and the upper end of the flap 220 may be connected to the main sheet 214 to make them continuous. The upper end of the flap 220 is located at the highest position (ceiling) of the upper curtain 210. The upper end of the flap 220 is located above the patient inside the isolation device 100. The ceiling support 320 is located inside the upper curtain 210. The ceiling support 320 supports the ceiling of the upper curtain 210 from below.

[0044] A hook 290 as shown in FIG. 15 is provided at a corner of the flap 220. The hook 290 has a hook body 292, a base 294, and a fastener 296. The hook body 292 has a C-shaped curved portion that can be hooked onto an engaged portion. The base end of the hook body 292 is fixed to the base 294. A magnet is provided on one or both of the base 294 and the fastener 296, and the base 294 and the fastener 296 are attracted to each other by magnetic force. The flap 220 is sandwiched between the base 294 and the fastener 296. This secures the hook 290 to the flap 220. By engaging the hook 290 secured to the flap 220 with, for example, the ceiling support 320, the flap 220 can be temporarily secured and the flap 220 can be prevented from sagging.

[0045] The lower portions of the first opening 214a and the second opening 214b extend linearly in the longitudinal direction along the side of the bed. The side portions of the first opening 214a and the second opening 214b extend linearly from the lower portions of the first opening 214a and the second opening 214b to the ceiling, approximately parallel to the sleeve 216. The lower portions and side portions of the first opening 214a and the second opening 214b are smoothly connected by curves.

[0046] The flap 220 and the main body sheet 214 are connected by a zipper 230 so that they can be opened and closed. The zipper 230 has two sliders 232 for opening and closing the zipper 230. By providing two sliders 232, any location on the zipper 230 can be partially opened. A tube 30 connected to the isolation device 100 can be inserted through this partial opening.

[0047] The first opening 214a and its flap 220 overlap with the first member 332 of the intermediate support body 330. The first member 332 constitutes a support for the flap of the first opening 214a. By removing the first member 332 of the intermediate support body 330, it is possible to remove an obstacle that overlaps with the first opening 214a when the flap 220 is in the open state.

[0048] The second opening 214b and its flap 220 overlap with the second member 334 of the intermediate support body 330. The second member 334 constitutes a support column for the flap of the second opening 214b. By removing the second member 334 of the intermediate support body 330, it is possible to remove an obstacle that overlaps with the second opening 214b when the flap 220 is open.

[0049] In this embodiment, the flap 220 is fixed (hanging) from the underside of the intermediate support body 330. Conversely, the flap 220 may be supported from below (from the inside of the curtain body 200) by the first member 332 and second member 334 of the intermediate support body 330. In other words, the flap 220 may be placed on the first member 332 and second member 334 of the intermediate support body 330.

[0050] In this embodiment, the intermediate support body 330 is disposed on the outside of the curtain body 200. The main body sheet 214 and the flap 220 of the curtain body 200 are fixed to the intermediate support body 330 with hook-and-loop fasteners or the like. When removing the first member 332 and the second member 334 of the intermediate support body 330, the fastening by the hook-and-loop fasteners is released and the first member 332 and the second member 334 are removed. Normally, both the first member 332 and the second member 334 are removed.

[0051] The isolation device 100 has duct connection ports 270 on both sides to which the duct of the suction device 500 is connected. The suction device 500 is connected to the duct connection ports 270 so that the air inside the isolation device 100 can be sucked by the suction device 500. The duct connection ports 270 are provided in the main body sheet 214 between the first opening 214a and the second opening 214b and the sleeve 216.

[0052] As shown in Figures 11 to 13, valves 280 are provided on the main sheet 214 constituting both sides of the curtain 200 and on the end sheet 212 of the isolation device 100. The valves 280 are provided on the inside of the curtain 200 so as to cover through-holes 285 provided in the curtain 200. The valves 280 are larger than the through-holes 285, and the outer periphery of the valve 280 overlaps with the curtain 200. The upper end of the valve 280 is fixed to the curtain 200. When negative pressure is created inside the curtain 200, the valves 280 open inward, allowing air outside the curtain 200 to be introduced through the through-holes 285. The curtain 200 may be provided with ring-shaped reinforcing members on the outer periphery of the valves 280 and around the through-holes 285 to maintain its flat shape.

[0053] A method of using the patient isolation device of this embodiment will be described using Figures 3 to 10. Figures 3 to 7 and 9 are side views that schematically show the isolation device of this embodiment in use. Figures 8 and 10 are front views that schematically show the isolation device of this embodiment in use.

[0054] As shown in Figure 3, before a patient enters the isolation device 100, the first member 332 and the second member 334 of the intermediate support 330 are first removed. To remove the first member 332, first, the connection between the flap 220 that covers the first opening 214a and the intermediate support 330, such as a hook-and-loop fastener, is released. Next, the ceiling-side end of the first member 332 is removed from the connecting pipe 336. Next, the floor-side end of the first member 332 is removed from the pocket 260 to release the first member 332 from its fixed position. The floor-side end of the second member 334 is removed from the pocket 260 to release the second member 334 from its fixed position.

[0055] 4, the flap 220 is then turned up to open the first opening 214a. To do this, the fastener 230 is first fully opened. Before the fastener 230 is opened, the flap 220 that closes the first opening 214a is detachably fastened to the main body sheet 214 at both sides and a bottom thereof by the fastener 230.

[0056] Next, the lower end of the flap 220 is grasped and lifted upward. As shown in Figure 4, the lifted flap 220 is placed on the ceiling of the isolation device 100. By placing the flap 220 on the ceiling of the isolation device 100 or by hooking the hook 290 provided on the flap 220 to the ceiling support 320, the flap 220 can be prevented from sagging. Because the first member 332 of the middle support 330 has been removed, the first opening 214a can be completely opened by lifting the flap 220.

[0057] 5, with the first opening 214a open, the patient 1 enters the isolation device 100. Because the first opening 214a opens up to the ceiling of the isolation device 100, the patient 1 can easily enter through the wide first opening 214a.

[0058] 6 shows a state in which a patient who has entered the room is lying on the bed with the flap 220 lowered and the zipper 230 closed. At this time, a suction device 500 is connected to the duct connection port 270 of the curtain 200. The suction device 500 is activated to create negative pressure inside the isolation device 100, preventing the patient's exhaled breath from leaking outside the isolation device 100. The air discharged from the suction device 500 is sterilized by an ultraviolet irradiation device 550 and / or a HEPA filter.

[0059] At this time, the negative pressure causes the valve 280 to open inward, allowing fresh air to flow into the isolation device 100 through the through-hole 285. A medical professional can visually confirm that the valve 280 is open. This allows the medical professional to visually confirm that the suction device 500 is operating and that the inside of the isolation device 100 is under negative pressure.

[0060] The suction device 500, the sterilization device, and the battery that drives them may be fixed to the caster bed 10 to which the isolation device 100 is attached. In this case, by closing the first opening 214a and the second opening 214b and continuing to drive the suction device 500 and the sterilization device as shown in Fig. 6, it is possible to prevent contamination from spreading to the surroundings even while the bed 10 is being moved. This makes it possible to move the bed 10 from a contaminated area to a clean area where treatment is performed while preventing contamination of the surroundings.

[0061] 7 and 8, the medical worker 6 performs the necessary treatment while the patient 1 is lying on the bed, and by hanging down the flap 220 at that time, the flap 220 can separate the patient 1's body, including the head, from the medical worker 6. The flap 220 that separates the patient 1 from the medical worker 6 is located above the patient 1. The upper end of the flap 220 and the main body sheet 214 are continuous above the patient 1, so the hanging flap 220 is located between the patient 1 and the medical worker 6.

[0062] To perform treatment, a medical worker 6 must connect a tube 30 extending from a dialysis machine 20 (a treatment device) to a shunt in the arm 2 of a patient 1. As shown in FIG. 8, the patient 1 extends only his or her arm 2 from the lower end of a flap 220 toward the medical worker 6. When connecting the tube 30 to the shunt (in shunt mode), it is preferable to maintain a negative pressure inside the isolation device 100 by increasing the air volume of the suction device 500 compared to normal mode. To reliably maintain a negative pressure inside the isolation device 100, it is preferable to set the air volume in shunt mode to at least three times that in normal mode.

[0063] As shown in FIG. 7 , it is important that the medical worker 6 can maintain a line of sight directly above the arm of the patient 1 where the shunt is installed, allowing the medical worker 6 to easily perform the puncture and not hindering the medical worker 6's work. The medical worker 6 can separate the body of the patient 1, including the head, from the medical worker 6 with a flap 220 without obstructing the medical worker's line of sight. The medical worker 6 can connect the needle inserted into the vein to the tubing 30 from the outside of the isolation device 100, making this work easier. In the subsequent operation of the dialysis machine 20, the isolation device 100 does not obstruct the medical worker 6's lead wire.

[0064] 9 and 10, the patient 1's arm is placed inside the flap 220, and the fastener 230 of the flap 220 is closed, leaving a space for inserting the tube 30. After that, the first member 332 and the second member 334 of the intermediate support 330 are reattached. By reattaching the first member 332 and the second member 334 and fixing the flap 220 to the first member 332, the distance between the flap 220 and the patient 1 increases. This makes it possible to maintain a large internal space in the isolation device 100 and alleviate the feeling of pressure felt by the patient 1 during treatment.

[0065] The fastener 230 has two sliders 232, allowing the tube 30 to pass through the gap between the two sliders 232. Keeping the flap 220 closed while treatment is being administered helps isolate the patient 1 from the rest of the room.

[0066] During treatment, the patient 1 is located inside the isolation device 100, and the dialysis machine 20 is located outside the isolation device 100, so the dialysis machine 20 can be isolated from the patient 1. Even if the patient 1 is infected with an infectious disease, the dialysis machine 20 can be prevented from becoming contaminated, and secondary infection via a treatment device such as the dialysis machine 20 can be prevented. In addition, the medical staff 6 operating the dialysis machine 20 can be isolated from the patient 1 during treatment such as dialysis.

[0067] Depending on the patient, the shunt may be placed in the left arm or the right arm. In the isolation device 100 of this embodiment, the first opening 214a, the second opening 214b, and the flap 220 are provided symmetrically on both sides of the isolation device 100, so that it can be adapted to the position of the patient's shunt.

[0068] In the above description, an infected patient is placed inside the isolation device 100 to protect the patient and medical personnel outside the isolation device 100. By reversing the air flow by the suction device 500, a non-infectious patient can be placed inside the isolation device 100 to isolate the patient from the contaminated external space. In this case, the inside of the isolation device 100 will be under positive pressure, so it is preferable to provide a valve 280 on the outside of the curtain 200 so that the air inside the isolation device 100 can be exhausted to the outside.

[0069] The embodiments disclosed herein should be considered to be illustrative in all respects and not restrictive. The scope of the present invention is defined by the claims, not by the above description, and is intended to include all modifications within the meaning and scope of the claims.
