Therefore, as described in the patent document below, an expert mounts a cleaning tool for cleaning the denture on the vehicle, travels to the site where the denture user waits, and the building at the site, for example, It has been proposed to clean dentures in general private houses, long-term care facilities, etc.

Japanese Unexamined Patent Publication No. 2001-161722

However, since fine dust and the like are rolled up during the cleaning work of the denture, there is a risk that the building becomes unsanitary due to the dust and the like in the on-site building such as a general private house or a long-term care facility. The present invention has been made in view of such a situation, and it is an object of the present invention to perform a denture cleaning work in a state where dust generated during the denture cleaning work is taken at a site where a denture user waits. And.

In order to solve the above problems, the present specification describes a box in which an operator can clean the artificial tooth with a cleaning tool, a suction machine that sucks air from the inside of the box, and the inside of the box. A filter disposed on at least one of the connecting path connecting the suction machine and the connecting path or the air discharging portion from the suction machine, and the end of the connecting path on the box side can be swung. The on-off valve is provided with a plate-shaped on-off valve arranged in the box, and the on-off valve swings in an open state by suction of air by the suction machine to clean the artificial tooth using the cleaning tool inside the box. by debris scattered along with adheres to the on-off valve, by weight of the scattering portion and said opening and closing valve attached to the on-off valve, discloses a vehicle you characterized in that swinging closed.

According to the present disclosure, a worker can travel by vehicle to a site where a denture user waits and perform denture cleaning work inside a box in the vehicle. This makes it possible to perform the denture cleaning work at the site where the denture user waits, while taking measures against dust generated during the denture cleaning work.

It is a figure which shows the vehicle from the viewpoint from the side. It is a figure which shows the vehicle from the viewpoint from above. It is a figure which shows the vehicle from the viewpoint from the rear. It is the schematic which shows the communication passage. It is the schematic which shows the on-off valve in an open state. It is the schematic which shows the on-off valve in a closed state. It is a figure which shows the denture in which the name card is embedded.

Even natural teeth, which are brushed every day, accumulate plaque in the mouth and tartar. For this reason, dental clinics and other clinics regularly recommend specialized removal of tartar, but dentures used in the same environment also have tartar and plaque, which causes an unpleasant odor. Etc. will adhere. And, at present, there are many dentures that cannot remove tartar, plaque, etc. that have adhered.

In recent years, more than 10 million elderly people nationwide wear and use dentures. In addition, as the number of elderly care facilities increases, the number of elderly people who move in while wearing dentures is increasing rapidly. It is left to the parents or helpers of the nursing care facility.

And, in most cases, parents, helpers, etc. can only wash the dentures that have been used for one day with a brush before going to bed and then soak them in a cleaning solution. In addition, if you are an elderly person living alone, even those tasks can be troublesome, and you may simply soak them in water.

However, deterioration, discoloration, and dirt deposition on the surface of dentures due to long-term use cannot be sufficiently suppressed with cleaning solutions. In addition, it is difficult to remove stains that have been deposited and deposited on the rough and deteriorated surface by rubbing with a brush and gradually becoming glossy, using a commercially available cleaning solution.

For this reason, toothbrushed dirt cannot be removed with a toothbrush, etc., and must be scraped off with a special cleaning tool such as a dental cutting bar. However, even if the denture is in a state where daily stains become tartar and stick to the surface of the denture, many elderly people cannot scrape the calculus with a special cleaning tool, so even if it is known that it is not good for hygiene. With the resignation that tartar cannot be removed, I use dentures with tartar every day.

Also, if you renew your new dentures about once every six months, you won't get this much dirt. However, in the past, the insurance coverage allowed the elderly to remake dentures free of charge once every six months, but since the elderly had to bear part of the treatment costs, due to financial reasons, the elderly People also tend to refrain from remaking and use the same thing for many years. For this reason, the surface of the denture deteriorates over time, and it becomes easy for the denture to become dirty.

In addition, since dentures are treated as miscellaneous goods like glasses after being attached to a patient, cleaning work of dentures is not covered by insurance under the current dental care system. Therefore, the cost of cleaning dentures will be borne by the patient, and even for patients who can go to the hospital, it is necessary to keep the dentures for several days for cleaning work, which causes inconvenience to the patient. Considering this, dental clinics rarely actively recommend denture cleaning work to patients for a fee. Moreover, it is very difficult for elderly people who move into long-term care facilities and have difficulty in going to the hospital to receive cleaning work, and they endure dentures with tartar and the like.

Therefore, a specialist such as a dental technician mounts a cleaning tool for cleaning the denture on the vehicle, travels to the site where the denture user waits, and at the site building, for example, a nursing facility, the denture Cleaning work may be performed. In such a case, toothbrushed dirt cannot be removed with a toothbrush, etc., so it is scraped off with a dental cutting bar, etc. The high-pitched mechanical noise peculiar to dentistry may cause discomfort to the residents of the facility. In addition, it is difficult to work inside the facility because dust such as sand used for finishing the cleaning work is scattered in the occupancy room and the public space of the facility.

In addition, even when a dust collector is used to prevent dust from scattering, the abrasive used during polishing is in the form of a paste, so the paste-like abrasive adheres to the inner wall of the suction pipe of the dust collector, and the filter of the dust collector. When the paste-like abrasive is sucked up to, the filter is clogged and the suction power is significantly reduced. In such a case, it is not possible to prevent the scattering of dust, and the work area becomes an unsanitary environment due to dust and the like.

In addition, when dentures are removed from the oral cavity due to cleaning work in a long-term care facility, it is very difficult for the person or a specialist to determine who the removed dentures are. be. For this reason, at the site of long-term care facilities, as the number of elderly people receiving long-term care increases, there are concerns about an increase in troubles such as denture misplacement that may occur during long-term care work in the facility and misplacement of dementia patients in the facility. Will be done. In addition, the only way to deal with denture misplacement is to rely on the helper's memory, and the helper's mental burden is not small. Furthermore, dirt and roughness on the surface near the trailing edge of the maxillary denture may cause aspiration pneumonia in the elderly.

In view of the above, examples of the present invention will be described in detail below with reference to the drawings as a mode for carrying out the present invention in order to solve the above problems.

1 to 3 show a denture cleaning and cleaning vehicle 10. The denture cleaning and cleaning vehicle 10 of FIGS. 1 to 3 is a form of the vehicle of the present invention, FIG. 1 is a side view of the denture cleaning and cleaning vehicle 10, and FIG. 2 is a plan view of the denture cleaning and cleaning vehicle 10. , FIG. 3 is an elevational view of the denture cleaning and cleaning vehicle 10. Further, in each drawing, the components of the denture cleaning and cleaning vehicle 10 are simplified and drawn large in order to make the drawing easy to understand.

The denture cleaning vehicle 10 includes a vehicle interior space S partitioned by a roof panel 20, a rear panel 22, and a pair of side panels 24. The vehicle interior space S covers the upper part of the waterproof floor surface 26, and the waterproof floor surface 26 is provided with a drainage pipe 28 that connects the vehicle interior space S and the outside of the vehicle. As a result, the waterproof floor surface 26 can be washed with water, and the washed water can be drained to the outside of the vehicle via the drain pipe 28.

A water supply tank 30 is arranged on the upper surface of the roof panel 20, and a sink 32 and a drainage tank 34 connected to the sink 32 are arranged in the vehicle interior space S. Then, water is supplied from the water supply tank 30 to the sink 32, and it is possible to wash the denture and the like in the sink 32. Further, the drainage used in the sink 32 is stored in the drainage tank 34.

Further, in the vehicle interior space S, a shelf-shaped fixed work table 36 is attached to one side of the pair of side panels 24, and the first work box 50 and the first work box 50 are mounted on the fixed work table 36. , A second work box 52, a denture detail cleaning work tool 54, a dental raise 56, and an ultrasonic cleaner 58 are arranged.

The first work box 50 is generally in the shape of a rectangular parallelepiped box, and is formed of a material such as plastic having a transparent entire surface. Therefore, the inside of the first work box 50 can be visually recognized from the outside. Further, the front surface 60 of the first work box 50 is connected to the upper surface of the first work box 50 via a hinge 62, and can be opened and closed. As a result, the inside of the first work box 50 is sealed by closing the front surface 60, and the inside of the first work box 50 is opened by opening the front surface 60. The front surface 60 is removable from the hinge 62, and the front surface 60 can be cleaned by removing the front surface 60 from the hinge 62. Further, a pair of through holes 64 are formed in the front surface 60. Each of the pair of through holes 64 is sized so that the worker's arm can be inserted.

Since the second work box 52 also has substantially the same structure as the first work box 50, detailed description thereof will be omitted. However, in the first work box 50, a pair of through holes 64 are formed in the front surface 60, but in the second work box 52, a pair of through holes 66 are formed in the pair of side surfaces. Like the through hole 64, the through hole 66 is also sized so that the worker's arm can be inserted.

The denture detail cleaning work tool 54 is a so-called dental engine, and is composed of a dental handpiece 68 and a controller 70. The dental handpiece 68 scrapes tartar and the like attached to the denture, and the controller 70 controls the operation of the dental handpiece 68. Further, the dental raise 56 is a device for brushing a denture with sand or the like, and is arranged inside the first work box 50. Further, the ultrasonic cleaner 58 is a device that uses ultrasonic waves to remove stains and the like adhering to the denture.

Further, an air compressor 72 is arranged below the fixed work table 36, and is used for cleaning dust and the like generated during work. On the other hand, above the fixed work table 36, a lighting device 74 is arranged above the side panel 24 to illuminate the upper surface side of the fixed work table 36.

Further, a dust collecting electric fan 76 and a connecting path 78 are arranged on the side panel 24 to which the fixed work table 36 is attached. Specifically, a hole for communicating the vehicle interior space S and the outside is formed in the side panel 24, and the dust collecting electric fan 76 is arranged in the hole. Further, the connecting path 78 is bifurcated at one end, and the bifurcated one end is connected to the first work box 50 and the second work box 52. The connecting path 78 is connected to the dust collecting electric fan 76 at the other end. As a result, by operating the dust collecting electric fan 76, air is sucked from the inside of the first work box 50 and the second work box 52, and air is sucked from the inside of the first work box 50 and the second work box 52 via the connecting path 78 and the dust collecting electric fan 76. , It is exhausted to the outside of the vehicle interior space S, that is, to the outside of the artificial tooth cleaning vehicle 10.

As shown in FIG. 4, the inner diameter of the air suction port from the first work box 50 and the second work box 52, that is, the side of the first work box 50 and the second work box 52 of the connecting path 78. When the inner diameter of the end portion is L1 and the inner diameter of the suctioned air discharge port, that is, the fan diameter of the dust collecting electric fan 76 is L2, L1: L2 = 1: 5. By setting the diameters of L1 and L2 in this way, a suitable suction force is exhibited, and a suction sound generated when air is sucked from the first work box 50 and the second work box 52. Can be made smaller.

A dust collecting bag 80 is attached to the air discharging portion of the dust collecting electric fan 76. The dust collecting bag 80 functions as a filter, and the dust collected by the electric fan 76 for collecting dust is prevented from being scattered. The dust collecting bag 80 is attached to and detached from the dust collecting electric fan 76.

Further, an on-off valve 82 is arranged at a connecting portion of the connecting path 78 to the first work box 50. As shown in FIG. 5, the on-off valve 82 includes a swing plate 86 and a swing shaft 88. The rocking plate 86 is generally rectangular and is held inside the connecting path 78 so as to be swung by the rocking shaft 88. The rocking plate 86 is held by the rocking shaft 88 in an inclined state so as to descend from the first work box 50 toward the inside of the connecting path 78, and is held by the rocking shaft 88 of the rocking plate 86. The holding portion is displaced from the center of the rocking plate 86. Due to the deviation of the holding portion, the length dimension from the swing shaft 88 of the swing plate 86 to the end on the diagonally downward side, that is, the length from the swing shaft 88 to the end on the side toward the inside of the connecting path 78. The dimension X1 is the length dimension from the swing shaft 88 of the swing plate 86 to the end on the diagonally upper side, that is, the length from the swing shaft 88 to the end on the side toward the inside of the first work box 50. It is longer than the dimension X2.

Therefore, the diagonally lower end of the rocking plate 86 is in contact with the bottom surface of the connecting path 78 due to the weight of the rocking plate 86, and the on-off valve 82 is normally closed. It is said to be in a state. However, even if the on-off valve 82 is closed, there is a clearance between the diagonally upper end of the rocking plate 86 and the inner wall of the connecting road 78 without blocking the entire inside of the connecting road 78. .. Further, when the dust collecting electric fan 76 is activated, air is sucked from the inside of the first work box 50, and the sucked air causes an end portion of the rocking plate 86 on the diagonally lower side as shown in FIG. Swings upward, and the on-off valve 82 is opened.

The denture cleaning vehicle 10 is a vehicle in which the rear space inside the van type vehicle is modified. That is, the denture cleaning vehicle 10 is a self-propelled vehicle. On the other hand, for example, a vehicle interior space S having the above structure may be formed inside a container or the like, and the container may be towed by a self-propelled vehicle. That is, it is possible to adopt a non-self-propelled vehicle in which the vehicle interior space S is formed, instead of the denture cleaning vehicle 10. Further, antibacterial treatment is applied to the floor and the wall surface inside the passenger compartment space S.

The denture cleaning work using the denture cleaning cleaning wheel 10 having the above structure will be described below.

First, the worker washes the denture entrusted by the client with water in the sink 32, and uses an air compressor 72 to dry the surface of the denture washed with water. Then, the operator confirms the location of tartar and dirt that are inconspicuous and tend to be overlooked when wet. Further, the operator selects an arbitrary one from a dental cutting bar, a sandpaper cone, and the like according to the condition of the surface of the denture, and attaches the selected one to the dental handpiece 68. Then, the worker grasps the dental handpiece 68 and the denture, inserts the arm into the through hole 64 of the second work box 52, and inside the second work box 52, the tartar adhering to the denture is removed. Remove and prepare the surface.

At this time, the dust collecting electric fan 76 is operating. Therefore, dust and the like generated when tartar is removed are collected inside the dust collecting bag 80 as the air is sucked by the dust collecting electric fan 76. As a result, the dust generated during the removal of tartar is prevented from being scattered in the vehicle interior space S, and the tartar can be removed in a clean state. Further, since the rotation noise peculiar to the dental equipment generated by the operation of the dental handpiece 68 is insulated by the second work box 52, there is a case where there is a person near the denture cleaning car 10. However, there is no need to worry about making the person uncomfortable. Further, since the dust is scattered inside the second work box 52, the dust may adhere to the front surface 60 of the second work box 52, making it difficult to see the inside. In such a case, the front surface 60 is removed from the second work box 52 and washed, so that the visibility inside the second work box 52 can be ensured.

Further, before and after the tartar removal work, as shown in FIG. 7, a personal identification name card 102 having a size of about 3 mm × 4 mm is embedded in the surface of the denture 100. This makes it possible for the helper or the like to determine who the denture 100 is in the state of being removed from the oral cavity.

Next, when the tartar removal work is completed, the operator grasps the denture, inserts the arm into the through hole 64 of the first work box 50, and uses the dental raise 56 inside the first work box 50. Clean the denture. At this time, in the cleaning operation using the dental raise 56, the paste-like polishing sand is attached to the surface of the denture, and the denture is polished together with the paste-like polishing sand by the dental raise 56. As a result, details such as the cervical region (the boundary between the tooth and the gum portion) are cleaned, and dirt that has permeated the entire surface of the denture is removed.

At this time, the dust collecting electric fan 76 is operating. Therefore, even if the polishing sand used for cleaning is scattered, the dust is collected inside the dust collecting bag 80 as the air is sucked by the dust collecting electric fan 76. As a result, even in the work using the dental raise 56, the scattering of dust is prevented, and the tartar can be removed in a clean state. As will be described in detail later, the paste-like polishing sand containing a large amount of water is not collected in the dust collecting bag 80, and the dry polishing sand 106 containing not much water is collected in the dust collecting bag 80. .. Further, since the operating sound of the dental raise 56 is insulated by the first work box 50, discomfort due to noise can be suppressed. Further, since the polishing sand 106 is scattered inside the first work box 50, the polishing sand 106 may adhere to the front surface 60 of the first work box 50, making it difficult to see the inside. In such a case, the front surface 60 is removed from the first work box 50 and washed, so that the visibility inside the first work box 50 can be ensured.

Further, since the on-off valve 82 is provided at the connecting portion between the first work box 50 and the connecting path 78, clogging of the dust collecting bag 80 due to the paste-like sand is prevented. Specifically, as shown in FIG. 5, in the dental raise 56, the rotating plate 104 for brushing the denture rotates counterclockwise. At this time, when the denture is polished by the dental raise 56 using the paste-like polishing sand, the paste-like polishing sand 106 is transferred from below the rotating plate 104 to the rocking plate 86 as shown in FIG. Scatter towards. Then, the scattered paste-like polishing sand 106 adheres to the portion of the rocking plate 86 below the rocking shaft 88. In particular, most of the paste-like polishing sand 106 containing a large amount of water adheres to the lower part of the rocking plate 86. At this time, the rocking plate 86, which was swinging in the open state due to the suction of air by the electric fan 76 for dust collection, has the polishing sand 106 adhering to the rocking plate 86 and the weight of the rocking plate 86. Will be closed. That is, the diagonally lower end of the rocking plate 86 comes into contact with the bottom surface of the connecting path 78. As a result, the paste-like polishing sand 106 is less likely to be collected inside the dust collecting bag 80, and clogging of the dust collecting bag 80 is prevented.

Further, when the on-off valve 82 is closed, the operator collects the polished sand 106 adhering to the rocking plate 86. As a result, the collected polished sand 106 can be reused, and waste of resources can be eliminated. As described above, the on-off valve 82 does not block the entire area of the connecting path 78 even in the closed state, and there is a clearance between the upper end portion of the rocking plate 86 and the connecting path 78. Therefore, even if the on-off valve 82 is closed, air is continuously sucked from the inside of the first work box 50, so that the work can be continuously performed inside the first work box 50. Then, after the work in the first work box 50 is completed, the polishing sand 106 adhering to the rocking plate 86 may be collected. This makes it possible to suppress interruption of work in the first work box 50.

Then, when the cleaning work using the polishing sand 106 is completed, the operator wash the denture with water in the sink 32 and dry the surface of the washed denture using the air compressor 72. Then, the operator confirms whether or not tartar and dirt, which are inconspicuous and tend to be overlooked in a wet state, are removed under sufficient brightness by the lighting device 74. At this time, when the operator confirms that the dirt has been removed, the brush of the rotating plate 104 of the dental raise 56 is replaced with a cloth buff. Then, the worker uses the dental raise 56 to perform the work of glazing the entire denture inside the first work box 50, and performs the work of cleaning the surface of the denture and the work of restoring the smooth surface.

Subsequently, when sufficient restoration of luster is confirmed, the denture is ultrasonically cleaned in an ultrasonic cleaner 58 filled with a sterilizing cleaning solution. As a result, the accuracy of cleaning and sterilizing the denture is improved. Then, after ultrasonic cleaning, the operator cleans the denture with water again in the sink 32, and uses an air compressor 72 to dry the surface of the washed denture. Then, the operator confirms whether sufficient cleaning and restoration of luster are properly performed under sufficient brightness by the lighting device 74. This completes the denture cleaning work.

As described above, dust and the like are hardly scattered in the vehicle interior space S, but dust and the like may be slightly scattered in the vehicle interior space S. In such a case, the vehicle interior space S can be kept clean by washing the waterproof floor surface 26 with running water or the like. Since the drainage pipe 28 connected to the existing drainage drain hole is arranged on the waterproof floor surface 26, the waterproof floor surface 26 can be cleaned by connecting a hose or the like to the drainage pipe 28. Later, the drainage used for the cleaning can be drained to an appropriate drainage ditch without being scattered on the facility premises.

As described above, according to the denture cleaning cleaning vehicle 10, all the cleaning work of the denture can be completed inside the vehicle, and the denture that is difficult to remove by normal processing in a nursing facility or the like. You can remove dirt and complete the restoration of the original smooth and glossy surface of the denture in the car. As a result, there have been various problems such as noise and dust during cleaning of dentures, and not only the user but also parents and helpers who care for them can endure the dirt and odor of the dentures. There was a problem that the dirt could not be removed and it had to be used, but such a problem can be solved by using the denture cleaning car 10 and the user etc. It is possible to eliminate the burden and unsatisfied feelings at once.

Furthermore, since the denture cleaning and cleaning vehicle 10 can be moved and installed at any place, it can be easily set up not only in nursing care facilities and private homes but also in large commercial facilities such as supermarkets. It is possible. For this reason, it is possible to open a demonstration of the work to people of all ages. As a result, many people will deepen their understanding of the original hygiene-favorable condition of dentures and increase maintenance opportunities to prevent deterioration of dentures and raise awareness of oral hygiene. It will also contribute to reducing the burden of medical expenses.
