Description

vehicle

The present invention relates to a vehicle capable of cleaning a denture.

The dentures are preferably cleaned by a specialist such as a dental technician at a predetermined frequency. However, it is troublesome for the users of dentures to visit professionals. For this reason, as described in the following patent documents, a specialist mounts a cleaning tool for cleaning the denture on the vehicle, and travels to the site where the user of the denture waits, and the building of the site, for example, It has been proposed to clean dentures in general private homes, nursing homes, etc.

JP 2001-161722 A

However, fine dust and the like roll up during denture cleaning work, and there is a risk that the building may become unsanitary due to dust and the like in a general private house, a building on site such as a care facility. The present invention has been made in view of such circumstances, and it is an object of the present invention to carry out the cleaning operation of the denture in a situation where the user of the denture waits for the dust generated at the time of the cleaning operation of the denture. I assume.

In order to solve the above problems, the present specification includes a box in which an operator can clean a denture with a cleaning tool, a suction machine for sucking air from the inside of the box, and the inside of the box A vehicle is disclosed that includes a filter that is disposed on at least one of a connection path that connects with a suction device, and the connection path or a discharge part of air from the suction device.

According to the present disclosure, the worker can travel to the site where the user of the denture waits for the vehicle, and can perform the denture cleaning work inside the box in the vehicle. As a result, at the site where the user of the denture waits, it is possible to perform the cleaning operation of the denture while taking measures against the dust generated at the time of the cleaning operation of the denture.

It is a figure which shows a vehicle in the viewpoint from the side. It is a figure which shows a vehicle in the viewpoint from upper direction. It is a figure which shows a vehicle in the viewpoint from back. It is the schematic which shows a communicating path. It is the schematic which shows the on-off valve of an open state. It is the schematic which shows the on-off valve of a closed state. It is a figure which shows the denture in which the name card was embedded.

Even with natural teeth brushing their teeth every day, plaque accumulates in the mouth and tartar also adheres. For this reason, in dental clinics etc. removal of specialized tartar is recommended regularly, but dental plaque which becomes the source of tartar and unpleasant smell in the same way in the same environment. Etc. And in the present situation, there are many dentures from which attached tartar, plaque, etc. can not be removed.

In recent years, more than 10 million elderly people in the country wear and use dentures. In addition, with the increase of nursing homes for the elderly, the elderly who move in while wearing dentures are also increasing rapidly, and the elderly people who need such care care about hygiene management such as cleaning of dentures used every day, It is entrusted to the guardian or the helper of the nursing home.

And, in most cases, parents, helpers, etc. can only do soaking in cleaning fluid after washing their dentures used for a day with a brush before going to bed. In addition, if you are an elderly person living alone, those work may be bothersome, and you may just be immersed in water.

However, deterioration and discoloration of denture surfaces due to long-term use, and deposition of dirt can not be sufficiently suppressed with cleaning fluid. In addition, it is difficult to remove dirt that has deposited and calcified on surfaces that are rubbed with a brush and gradually become rough and degraded, using a commercially available cleaning solution or the like.

For this reason, it is impossible to remove tartarized dirt with a toothbrush or the like, and it can only be scraped off using a dedicated cleaning tool such as a dental cutting bar. However, even with dentures in the condition where daily dirt becomes tartar and sticks to the surface of dentures, many elderly people can not scrape tartar etc. using dedicated cleaning tools, so it is known that they are not preferable for hygiene, I use dentures that have been attached to calculus etc. every day in a stir that calculus can not be removed.

Also, if you adjust your new dentures at a pace of about once every six months, you will not get the stains so far. However, in the past it was possible for the elderly to re-create dentures once a half year free of charge by insurance application, but after the elderly people need to bear a part of the medical expenses, the elderly Also tend to use the same thing for many years without reworking. For this reason, aging of the surface of the denture progresses and it becomes easy to get dirty.

In addition, since dentures are treated as sundries like glasses, etc. after being worn on patients, denture cleaning is not covered by insurance under the current dental care system. Therefore, the cost of cleaning dentures is a patient's own expense, and even for patients who can go to the hospital, it is necessary to leave dentures for several days for cleaning work, causing inconvenience to patients, etc. As a result, dental clinics do not have the possibility to actively recommend cleaning the dentures to patients for a fee. It is extremely difficult for elderly people, who have difficulty moving to the hospital, etc., to move into nursing homes, etc., to receive cleaning work, and it is used to endure dentures with tartar etc. attached.

Therefore, a specialist such as a dental technician mounts a cleaning tool for cleaning the denture on the vehicle, and travels to the site where the user of the denture waits, and in the building of the site, for example, a care facility etc. It is possible to do the cleaning work. In such a case, soiled dirt can not be removed with a toothbrush or the like, so it is scraped off using a dental cutting bar or the like, but if work using a cutting bar or the like is performed in a facility, The high mechanical sound of keen, which is unique 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 polished sand that is used at the time of finishing the cleaning work scatters in the room and public space of the facility.

In addition, even when a dust collector is used to prevent scattering of dust, the abrasive used at the time of polishing is paste-like, 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 pasty abrasive is sucked up, the filter is clogged and the suction power is significantly reduced. In such a case, scattering of dust can not be prevented, and the area around the work becomes an unsanitary environment due to dust and the like.

In addition, in the state where dentures are removed from the oral cavity by cleaning work in a nursing home or the like, it is very difficult for the person or a specialist to determine who the dentures are removed. is there. Therefore, in the field of the nursing home, with the increase of elderly people who receive care, there is concern about the increase of troubles such as the wrong placement of dentures that may occur during the nursing care work in the institution and the leaving of dementia patients in the institution. Will be Also, the only way to deal with false denture errors is to rely on the helper's memory, and the helper's mental burden is not small. Furthermore, if the surface of the upper denture near the rear edge or the like gets dirty, it may cause aspiration pneumonia in the elderly.

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

The denture cleaning and washing car 10 is shown in FIGS. 1 to 3. 1 to 3 is one form of the vehicle of the present invention, and FIG. 1 is a side view of the denture cleaning vehicle 10, and FIG. 2 is a plan view of the denture cleaning vehicle 10. , FIG. 3 is an elevation view of the denture cleaning and washing car 10. Moreover, in each figure, in order to make a drawing intelligible, the component of the denture cleaning and washing vehicle 10 is simplified and drawn large.

The denture cleaning and washing vehicle 10 includes a cabin space S partitioned by a roof panel 20, a rear panel 22, and a pair of side panels 24. The passenger compartment space S covers the upper side of the waterproof floor 26, and on the waterproof floor 26, a drainage pipe 28 which communicates the passenger compartment space S with the outside of the vehicle is disposed. Thereby, it is possible to wash the waterproof floor 26 with water, and to flush the washing water to the outside of the vehicle through the drain pipe 28.

A water supply tank 30 is disposed on the top surface of the roof panel 20, and a sink 32 and a drainage tank 34 connected to the sink 32 are disposed in the passenger compartment space S. Then, water is supplied from the water supply tank 30 to the sink 32, and the sink 32 can clean the dentures and the like. The drainage used in the sink 32 is stored in the drainage tank 34.

In the compartment space S, a shelf-like fixed workbench 36 is attached to one side of the pair of side panels 24, and on the fixed workbench 36, a first work box 50 and a first work box 50 are provided. A second work box 52, a denture detail cleaning implement 54, a dental raise 56, and an ultrasonic cleaner 58 are provided.

The first work box 50 is generally in the form of a rectangular box, and the entire surface is made of a transparent material such as plastic. 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 the hinge 62 and can be opened and closed. Thereby, the inside of the first work box 50 is sealed by closing the front face 60, and the inside of the first work box 50 is opened by opening the front face 60. The front surface 60 is detachable from the hinge 62, and the front surface 60 can be cleaned by removing the front surface 60 from the hinge 62. Further, the front surface 60 is formed with a pair of through holes 64. Each of the pair of through holes 64 is sized to allow insertion of the worker's arm.

The second work box 52 also has substantially the same structure as the first work box 50, and thus the detailed description will be omitted. However, in the first work box 50, the pair of through holes 64 is formed in the front surface 60, but in the second work box 52, the pair of through holes 66 is formed in the pair of side surfaces. Similarly to the through hole 64, the through hole 66 is also sized so that the arm of the worker can be inserted.

The denture detail cleaning implement 54 is a so-called dental engine, and is configured of a dental handpiece 68 and a controller 70. The dental handpiece 68 is for scraping calculus or the like attached to the denture, and the controller 70 controls the operation of the dental handpiece 68. The dental raise 56 is a device for polishing the denture with sand or the like, and is disposed inside the first work box 50. The ultrasonic cleaner 58 is a device for removing dirt and the like adhering to the denture using ultrasonic waves.

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

Further, on the side panel 24 to which the fixed type work table 36 is attached, a dust collecting electric fan 76 and a connection path 78 are disposed. More specifically, a hole is formed in the side panel 24 to communicate the vehicle compartment space S with the outside, and the dust collection electric fan 76 is disposed in the hole. The connection 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 connection passage 78 is connected to the dust collecting electric fan 76 at the other end. As a result, air is sucked from the inside of the first work box 50 and the second work box 52 by operating the dust collection electric fan 76, and the air is sucked through the connection path 78 and the dust collection electric fan 76. The air is exhausted to the outside of the cabin space S, that is, to the outside of the denture cleaning and washing car 10.

Note that, as shown in FIG. 4, the inner diameters of the air suction ports from the first work box 50 and the second work box 52, that is, the sides of the first work box 50 and the second work box 52 of the connection passage 78. Assuming that the inner diameter of the end of L is L1, and the inner diameter of the exhaust port of the sucked air, that is, the fan diameter of the electric fan 76 for dust collection is L2, L1: L2 = 1: 5. By setting the size of the diameter of L1 and L2 in this manner, a suitable suction force can be exhibited, and suction noise generated when air is sucked from the first work box 50 and the second work box 52 Can be reduced.

Also, a dust collection bag 80 is attached to the air discharge part of the dust collection electric fan 76. The dust collection bag 80 functions as a filter, and scattering of dust discharged by the dust collection electric fan 76 is prevented. The dust collection bag 80 is detachable from the dust collection electric fan 76.

Further, an open / close valve 82 is disposed at a connection portion of the connection path 78 to the first work box 50. As shown in FIG. 5, the on-off valve 82 is constituted by a rocking plate 86 and a rocking shaft 88. The rocking plate 86 is generally rectangular, and is retained inside the connection passage 78 so as to be able to slide by a rocking shaft 88. The rocking plate 86 is held by the rocking shaft 88 in an inclined state so as to descend downward from the first work box 50 toward the inside of the connection path 78. The holding portion is offset from the center of the rocking plate 86. Due to the displacement of the holding portion, the length dimension from the swinging shaft 88 of the swinging plate 86 to the end on the diagonally lower side, that is, the length from the swinging shaft 88 to the end toward the inside of the connection passage 78 The length dimension X1 is a length dimension from the rocking shaft 88 of the rocking plate 86 to the end on the diagonally upper side, that is, a length from the rocking shaft 88 to the end toward the inside of the first work box 50. The length dimension is longer than X2.

Therefore, the lower end of the rocking plate 86 is in contact with the bottom surface of the connection passage 78 by the weight of the rocking plate 86 as shown in FIG. 6, and the on-off valve 82 is normally closed. It is in the state. However, even when the on-off valve 82 is closed, there is a clearance between the end portion on the diagonally upper side of the swing plate 86 and the inner wall of the connection passage 78 without closing the entire inside of the connection passage 78. . Further, when the dust collection electric fan 76 operates, air is sucked from the inside of the first work box 50, and the suctioned air causes the end portion on the diagonally lower side of the swing plate 86 as shown in FIG. Swings upward, and the on-off valve 82 is opened.

The denture cleaning and washing vehicle 10 is a vehicle in which the rear space in a van-type vehicle is modified. That is, the denture cleaning and washing vehicle 10 is a vehicle capable of traveling by itself. On the other hand, for example, a compartment space S of the above-described structure may be formed inside a container or the like, and the container may be pulled by a vehicle capable of traveling by itself. That is, it is possible to adopt a non-self-propelled vehicle in which the cabin space S is formed in place of the denture cleaning and washing vehicle 10. In addition, the floor and the wall inside the cabin space S are subjected to an antibacterial treatment.

An operation for cleaning a denture using the denture cleaning and washing car 10 having the above-described structure will be described below.

First, the worker rinses the denture, which has been deposited by the client, in the sink 32, and uses the air compressor 72 to dry the surface of the rinsed denture. Then, the worker checks the place of tartar and dirt which tends to be overlooked inconspicuously in the wet state. In addition, the worker selects an arbitrary one from a dental cutting bar, a sandpaper cone, etc. according to the condition of the surface of the denture, and mounts the selected one on the dental handpiece 68. Then, the operator holds the dental hand piece 68 and the denture, inserts the arm into the through hole 64 of the second work box 52, and in the second work box 52, the tartar adhering to the denture Remove and trim the surface.

At this time, the dust collection electric fan 76 is operating. For this reason, dust and the like generated when the tartar is removed is collected inside the dust collection bag 80 as the air is sucked by the dust collection electric fan 76. As a result, scattering of dust generated at the time of tartar removal into the passenger compartment space S is prevented, and tartar removal work can be performed in a clean state. In addition, since the rotation noise and the like unique to the dental equipment generated with the operation of the dental handpiece 68 are shielded by the second work box 52, the case where there is a person near the denture cleaning and washing car 10 There is no need to worry that the person feels uncomfortable. In addition, since the dust scatters 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 visually recognize the inside. In such a case, it is possible to secure the visibility inside the second work box 52 by removing the front face 60 from the second work box 52 and washing it.

In addition, before and after the tartar removal operation, as shown in FIG. 7, a personal identification name card 102 of about 3 mm × 4 mm is embedded in the surface of the denture 100. As a result, it becomes possible for the helper or the like to determine who is the denture 100 in a state of being removed from the oral cavity.

Next, when the operation for removing the calculus is completed, the operator holds 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 dentures. At this time, in the cleaning operation using the dental raise 56, paste-like polished sand is attached to the surface of the denture, and the denture is polished by the dental raise 56 together with the paste-like polished sand. As a result, cleaning of details such as the cervical region (the boundary between the teeth and the gum part) and removal of stains on the surface of the entire denture are performed.

At this time, the dust collection electric fan 76 is operating. Therefore, even if the polishing sand used for cleaning is scattered, the dust is collected inside the dust collection bag 80 as the air is sucked by the dust collection electric fan 76. As a result, even in the operation using the dental raise 56, the scattering of dust is prevented, and it is possible to perform the operation of removing the tartar in a clean state. Although described later in detail, 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 little water is collected in the dust collecting bag 80. . In addition, since the operation noise of the dental raise 56 is noise-insulated by the first work box 50, the discomfort due to the noise can be suppressed. In addition, since the polishing sand 106 scatters 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 visually recognize the inside. In such a case, it is possible to secure the visibility inside the first work box 50 by removing the front face 60 from the first work box 50 and washing it.

Furthermore, since the on-off valve 82 is disposed at the connection portion between the first work box 50 and the connection path 78, clogging and the like of the dust collection bag 80 with paste-like polishing sand can be prevented. Specifically, as shown in FIG. 5, in the dental raise 56, a rotating plate 104 for brushing a denture rotates counterclockwise. At this time, when the denture is polished by the dental raise 56 using paste-like polishing sand, as shown in FIG. Splash towards. Then, the scattered paste-like polishing sand 106 adheres to a portion below the rocking shaft 88 of the rocking plate 86. In particular, most of the paste-like polishing sand 106 containing a large amount of water adheres to the lower portion of the oscillating plate 86. At this time, with the suction of air by the dust collection electric motor 76, the rocking plate 86 rocked in the open state is the polishing sand 106 attached to the rocking plate 86, and the weight of the rocking plate 86. Is closed. That is, the lower end of the rocking plate 86 is in contact with the bottom surface of the connection passage 78. As a result, the paste-like polished sand 106 is less likely to be collected inside the dust collection bag 80, and clogging of the dust collection bag 80 is prevented.

Further, when the on-off valve 82 is closed, the operator recovers the polishing sand 106 attached to the rocking plate 86. This makes it possible to reuse the recovered polishing sand 106, and it is possible to eliminate waste of resources. As described above, the on-off valve 82 does not close the entire area of the connection passage 78 even in the closed state, and there is a clearance between the upper end of the swing plate 86 and the connection passage 78. For this reason, since air is continuously sucked from the inside of the first work box 50 even when the on-off valve 82 is closed, the work can be continued inside the first work box 50. Then, after the work in the first work box 50 is completed, the polished sand 106 attached to the rocking plate 86 may be recovered. This makes it possible to suppress the interruption of the work in the first work box 50.

Then, when the cleaning work using the polishing sand 106 is completed, the worker rinses the denture in the sink 32 and uses the air compressor 72 to dry the surface of the rinsed denture. Then, the worker checks whether the calculus 74 or the dirt that is likely to be overlooked inconspicuously in the wet state is sufficiently bright by the lighting device 74. At this time, when the worker confirms that the dirt is removed, the brush of the rotating plate 104 of the dental raise 56 is replaced with a cloth buff. Then, using the dental raise 56, the worker performs the polishing operation of the entire denture in the first work box 50, and performs the surface cleaning of the denture and the restoration operation of the smooth surface.

Subsequently, when restoration of sufficient gloss is confirmed, the denture is subjected to ultrasonic cleaning in an ultrasonic cleaner 58 filled with a sterilizing cleaning solution. This enhances the accuracy of cleaning and disinfecting the denture. Then, after ultrasonic cleaning, the worker again rinses the denture with the sink 32 and uses the air compressor 72 to dry the surface of the rinsed denture. Then, the worker confirms whether sufficient cleaning and restoration of luster are properly performed under sufficient brightness by the lighting device 74. This completes the cleaning operation of the denture.

As described above, dust and the like hardly scatter in the cabin space S, but dust and the like may scatter slightly. In such a case, the cabin space S can be kept clean by washing the waterproof floor surface 26 with running water or the like. And since the drainage pipe 28 connected to the existing hole for draining drains is arrange | positioned by the waterproof floor surface 26, the cleaning of the waterproof floor surface 26 is carried out by connecting a hose etc. to the drainage pipe 28. Later, the drainage used for the cleaning can be drained into an appropriate drainage ditch without being scattered in the facility site.

As described above, according to the denture cleaning and cleaning car 10, it is possible to complete all the denture cleaning work inside the vehicle, and it is difficult to remove dentures that are difficult to remove by ordinary processing in a care facility or the like. You can remove stains and complete restoration of the original smooth surface of denture in the car. As a result, conventionally, there are various problems such as noise and dust at the time of denture cleaning work, and not only the user himself, but also the guardian and the helper who cares etc. endure the dirt and smell of the denture, There is a problem that you can not but get rid of the dirt and you have to use it, but you can solve all these problems by using the denture cleaning and washing car 10, and users It is possible to eliminate the burden and unfulfilled feelings at once.

Furthermore, since the denture cleaning and washing car 10 can be moved to any place and installed, it can be easily set up not only in nursing homes and private homes, but also in large commercial facilities such as supermarkets, for example. It is possible. This makes it possible to demonstrate the work to people of all ages. As a result, many people deepen their understanding of the desirable condition of the denture in terms of hygiene and increase maintenance opportunities, thereby preventing deterioration of the denture and improving awareness of hygiene in the oral cavity. It also contributes to reducing the burden of medical expenses.
