Description

  The present invention relates to a suction device, a suction tube for a suction device, and a cap for a suction device for sucking unnecessary matter in the oral cavity in dentistry.

  During dental treatment, for example, when a tooth is cut, the tooth powder and small pieces of the cut tooth and water supplied for lubrication and cooling accumulate in the oral cavity. In addition, in the case of an elderly person or when oral care is stagnant, food residues, plaque, etc. accumulate on the tooth surface and mucous membrane surface in the oral cavity. Therefore, a suction device is inserted into the oral cavity to remove them by suction. For example, Patent Documents 1 and 2 disclose techniques related to conventional suction devices.

  The device disclosed in Patent Document 1 discloses a configuration in which a suction tip is attached to the tip of a suction pipe. According to this, the suction tip is constituted by the base portion made of a relatively hard resin and the flexible portion made of a soft resin, thereby preventing the suction port from being deformed.

  In the device described in Patent Document 2, a hole is provided on a side surface of a straight pipe, and a technique for sucking and supplying the hole is disclosed. At this time, the front end portion of the straight pipe is buried so as to be thicker than the straight pipe, and the end portion is curved to prevent damage.

  However, in the invention described in Patent Document 1, if the hole for suction is to be enlarged, it is necessary to increase the angle at which the end is cut obliquely. For this reason, when inserted into the oral cavity, the tip of the tooth collides with a part of the oral cavity such as a tooth, which may hinder smooth suction.

  Further, in the invention described in Patent Document 2, when the suction port is arranged at a target site, the tip portion may collide with any site in the oral cavity and the intended suction may not be performed. In Patent Document 2, it is difficult to suppress the collision itself, although it is possible to suppress problems (scratches) caused by the collision.

  In particular, elderly people, children, and the like cannot open their mouths large or have a small inside of the oral cavity, and thus a device for smoother suction is required.

  Then, this invention makes it a subject to provide the suction device which can suck | suck smoothly in an oral cavity in view of the said problem. Moreover, the suction tube for suction devices used for the said suction device and the cap for suction devices are provided.

  The present invention will be described below. For ease of understanding, reference numerals used in the drawings are added, but the present invention is not limited to the forms indicated by the reference numerals.

  The invention according to claim 1 is a cylindrical suction pipe (20), and a cylindrical cap having a bottom on one side disposed so as to cover the front end of the suction pipe by inserting the front end of the suction pipe (30), and the suction pipe has a suction port (21) which is a hole communicating with the outer periphery of the cylindrical inner and outer sides, and at the tip of the opposite side of the suction port across the axis, The suction tube side notch (22), which is a thin part, is provided, and the cap has an opening (31) at a position overlapping the suction port, and a wall (32) standing from the edge of the opening. And a brush (33) disposed on the end surface of the wall portion, and a cap side notch portion (34) which is a thin portion formed at a position corresponding to the suction tube side notch portion. The suction device (10).

  According to a second aspect of the present invention, in the suction device (10) according to the first aspect, the length of the brush (33) is not less than 0.5 mm and not more than 5.0 mm.

  The invention according to claim 3 is an inclined surface and a curved surface at a portion other than the suction tube side notch (22) of the end surface of the suction tube (20) of the suction device (10) according to claim 1 or 2. At least one of them is formed.

  The invention described in claim 4 is cylindrical and has a suction port (21) that is a hole that communicates the inside and outside of the tube in the outer peripheral portion, and a tip portion on the opposite side of the suction port across the axis. Is a suction pipe (20) for a suction device provided with a suction pipe side notch (22), which is a thin part.

  The invention according to claim 5 is a cylindrical shape having a bottom on one side, an opening (31) which is a hole communicating with the outer periphery of the cylindrical shape, and a wall erected from the edge of the opening A cap-side notch (which is a portion formed thin at the tip opposite to the opening across the axis, with a portion (32) and a brush (33) disposed on the end surface of the wall. 34) is a cap (30) for a suction device.

On the other hand, FIG. 5 is an exploded view in a section along the longitudinal direction (axial direction) of the suction device 10, FIG. 5 (a) is a side view, FIG. 5 (b) is a plan view, and FIG. FIG.
The suction device 10 will be described with reference to FIGS.

  The suction device 10 includes a suction tube 20 and a cap 30.

The suction tube 20 is a member that transmits a suction force from a suction device (not shown) and actually performs suction from the oral cavity.
In this embodiment, the suction tube 20 has a tubular shape that is not bent at a portion where the cap 30 at the tip thereof is inserted, and is formed of metal or hard resin. That is, it is made of a material that does not deform when inserted into the oral cavity. The cross-sectional shape of the cross section perpendicular to the axis of the suction tube 20 is not particularly limited, and a circular shape (circular tube), a rectangular shape (square tube), or the like can be used.
1 to 5 show only the tip side of the suction tube 20 where suction is performed, but the end opposite to the tip side is connected to a flexible tube such as a hose. It is finally connected to the suction device via.

  Of the suction tube 20, the shape of the tip of the suction tube 20 appears well in FIGS. 3 to 5. As can be seen from these drawings, the suction tube 20 is provided with a suction port 21 at its distal end, which is a hole that penetrates the tube wall and communicates the inside and the outside. The size and shape of the suction port 21 are not particularly limited, but it is easy to provide an opening with a large area by providing the suction port 21 on the outer periphery of the tube. In some cases, it is preferable to suck a large object (a large piece of teeth, a food residue), and the effect becomes more remarkable particularly when a large suction port is required. Although the size of the suction port depends on the thickness of the suction tube, it is preferably 8 mm or more and 25 mm or less at the place where the distance between the opposite edges of the suction port is the smallest.

  Further, the suction tube side notch 22 formed thinner than the other end of the suction tube 20 on the opposite side across the axis (the axis of the tube) with respect to the portion where the suction port 21 is disposed. Is provided. That is, in this part, it is thin like the edge (edge) of the front-end | tip of the suction tube 20 was excluded. As a result, even if the suction port 21 is moved when the suction device 10 is inserted into the oral cavity, the tip of the suction device 10 is unlikely to hit the site in the oral cavity, and smooth suction and handling are possible.

  In this embodiment, as can be seen from FIG. 4A, the tip of the suction tube 20 is inclined so as to become thinner toward the tip. However, the shape is not limited to this and may be any other shape as long as it narrows toward the tip. An example is shown in FIG. 6A shows an example of the suction tube 20 ′ in which the suction tube side notch 22 ′ is formed by a step, and FIG. 6B shows the suction tube 20 in which the suction tube side notch 22 ″ is formed by an arc shape. FIG. 6C shows an example of the suction tube 20 ′ ″ in which the suction tube side notch 22 ′ ″ is formed by combining the slope and the step.

  Returning to FIGS. 1 to 5, the description of the suction tube 20 will be continued. In the suction tube 20, an inclined surface is formed so as to lack this edge at the edge (edge) between the suction tube side notch 22 and the tip surface of the suction tube 20, which is generated by the suction tube side notch 22. And it is preferable that the site | part 23 which is at least one of a curved surface is formed. Thereby, it can prevent that the front-end | tip of the suction tube 20 becomes an acute angle. The shape of the portion 23 may be inclined as in this embodiment, may be an arc shape, or a combination thereof.

  The tip of the suction tube 20 may be open or closed. However, as will be described later, the tip is closed by overlapping a part of the cap 30. Therefore, in view of the fact that the cap 30 can be easily closed, there is no need to further close the tip by other means. Therefore, it is preferable that the tip of the suction tube 20 is open from the viewpoint of a simpler configuration, productivity, and cost.

The cap 30 is a member that is attached to the distal end portion of the suction tube 20 and functions to perform suction more comfortably for a patient or a practitioner.
The cap 30 is a bottomed cylindrical member that is closed with a bottom disposed at one end, and has an inner diameter that is substantially the same as the outer diameter of the suction tube 20. The cross-sectional shape in the direction orthogonal to the axis of the cylinder is a shape corresponding to the suction tube 20.
The cap 30 is made of a soft elastic material, thereby preventing the patient's oral cavity from being damaged. The type of soft material is not particularly limited. For example, natural rubber, isoprene rubber, styrene butadiene rubber, butadiene rubber, chloroprene rubber, nitrile rubber, butyl rubber, ethylene propylene rubber, urethane rubber, silicone rubber, acrylic Rubber materials such as rubber, chlorosulfonated polyethylene rubber, fluororubber, hydrogenated nitrile rubber, epichlorohydrin rubber, polysulfide rubber and the like are preferable, and it is preferable not to have a sponge structure. In addition, synthetic resin materials such as polyvinyl chloride, various nylons, ethylene vinyl acetate, polychlorotrifluoroethylene, polyethylene, polysulfone, polypropylene, and polyphenyl sulfide are also suitable as thermosetting elastomers and thermoplastic elastomers.

  The shape of the cap 30 appears well in FIGS. As can be seen from these drawings, the cylindrical outer periphery of the cap 30 is provided with an opening 31 through the inside and outside, and a wall portion 32 is erected so as to border the opening 31. Accordingly, it can be said that a short cylinder is formed by the wall portion 32. A brush 33 is provided on the front end surface of the wall portion 32.

  The shape and size of the opening 31 are the same as or larger than the suction port 21 of the suction tube 20 described above. Thereby, the cap 30 does not close the suction port 21 and does not inhibit the suction.

  The height of the wall portion 32 (the height standing from the edge of the opening 31) is not particularly limited, but is preferably 0 mm or more and 5 mm or less. Since it may be 0 mm, the wall portion 32 may not be provided. At this time, a brush 33 can be provided along the edge of the opening 31. However, by providing the wall portion 32, the opening formed by the end surface of the wall portion 32 can be a planar opening without bending, so the wall portion 32 is provided and its height is greater than 0 mm. It is more preferable. On the other hand, if the height of the wall portion 32 is greater than 5 mm, the suction device 10 becomes thicker (the size in the direction perpendicular to the axis of the suction tube 20 becomes larger), so that the movement in the oral cavity cannot be performed smoothly. There is a fear.

The brush 33 is not necessarily arranged, but by providing the brush 33, it is possible to perform suction while scraping, and the efficiency of cleaning in the oral cavity by suction can be improved. In the absence of the wall 32 and the brush 33, if the suction force of the suction device is too strong, the mucosal surface is sucked and the mucous membrane may be damaged or the suction operation may not be performed smoothly. In order to prevent this, it is effective to temporarily provide a mechanism for adjusting the strength of the suction force of the suction device, but the device becomes complicated. The complication of the apparatus has the disadvantage that the cost is increased and the maintenance is troublesome. Therefore, it is preferable to provide the brush 33 in particular, because the possibility that the mucosal surface is sucked can be reduced, and the suction force can be adjusted to some extent by adjusting the angle during use. From this viewpoint, the length of the brush 33 is preferably 0.5 mm or greater and 5.0 mm or less. If this is less than 0.5 mm, the mucosal surface is sucked when the suction force of the suction device is too strong, and the suction operation is temporarily stopped. Therefore, it is necessary to temporarily weaken the suction force of the suction device. On the other hand, when the length of the brush exceeds 5.0 mm, there is a possibility that problems such as the suction may not be smooth unless the suction force of the suction device is increased.
The brush 33 can be produced by arranging the same material as the wall portion 32 in a thin and countless manner. According to this, it is possible to form the brush 33 integrally with the wall portion 32 (or the entire cap 30).

In addition, a cap side notch portion 34 that is thin in a shape corresponding to the suction tube side notch portion 22 is provided at a tip portion of the cap 30 that faces the outer peripheral portion where the opening 31 is formed. . The cap side cutout 34 is a part of the bottom and is closed.
The cap side notch portion 34 corresponds to the suction tube side notch portion 22 provided in the suction tube 20 and is provided so that the effect of the suction tube side notch portion 22 can be exhibited even when the cap 30 is attached. . Therefore, when the suction tube side notch has another shape (for example, FIGS. 6A to 6C), it is preferable that the shape of the cap side notch corresponds to this.

  The suction tube 20 and the cap 30 described above are combined as follows to form the suction device 10. The combined state is clearly shown in FIGS. As can be seen from these drawings, the cap 30 is attached to the tip of the suction tube 20 on the side where the suction port 21 is disposed. That is, a combination is made by inserting the suction port 21 side end of the suction tube 20 into the cap 30.

At this time, the suction port 21 of the suction tube 20 and the opening 31 of the cap 30 are arranged so as to overlap each other. As a result, as can be seen from FIG. 2C, the suction port 21 of the suction tube 20 is appropriately connected to the outside and can be sucked.
As can be seen from FIG. 3A, the suction tube side notch portion 22 of the suction tube 20 is disposed so as to overlap the cap side notch portion 34 of the cap 30. Thereby, the form of the suction tube side notch 22 can be utilized.
Since the tip of the suction tube 20 is closed by the cap 30, the suction from the suction port 21 is not hindered even if the tip of the suction tube 20 is open.

  In addition, it is preferable that each part is arrange | positioned as mentioned above by inserting the suction pipe 20 to the bottom part of the cap 30. FIG. That is, the tip of the suction tube 20 is preferably in contact with the bottom of the cap 30. Thereby, the suction tube 20 also functions as the core of the entire cap 30, and deformation of the cap 30 can be suppressed. If the deformation is large, there is a possibility that the opening for suction may be blocked, and this can be avoided.

According to such a suction device 10, for example, it operates as follows.
That is, as a basic function of the suction device 10, an object can be sucked into the suction tube 20 through the inside surrounded by the wall portion 32 of the cap 30, the opening 31, and the suction port 21 of the suction tube 20. Therefore, by inserting the tip of the suction device 10 into the oral cavity, water, tooth cutting pieces, tooth small pieces, food residues, and the like existing in the oral cavity can be sucked and removed.
In the present invention, such a suction port 21 is provided on the outer peripheral surface (side surface) of the suction tube 20, so that a larger hole can be formed as compared with a case where the end surface of the tube is a suction port. Therefore, a large thing can be sucked in and clogging can be suppressed.

  Moreover, since the edge (edge) of the edge part on the opposite side to the site | part in which the suction port 21 and the opening 31 were provided, it is less likely to collide with the site | part in an oral cavity, and smooth suction can be performed. Is possible. Moreover, the front-end | tip of the suction device 10 can be inserted to the back in the oral cavity. Since the cap 30 is formed of a soft elastic material, even if it hits any part of the oral cavity, the part is not damaged.

  Even in a simple form in which the tip of the suction tube 20 is open, the tip of the suction tube 20 is blocked by the cap 30, so that the suction force can be appropriately exerted. Moreover, if it is the structure which can be inserted so that the front-end | tip of the suction pipe 20 may contact the bottom part of the cap 30, a deformation | transformation of the cap 30 will be suppressed reliably and suction will not be prevented, and it will become a more reliable suction instrument.

  Further, if at least one of the wall portion 32 and the brush 33 as described above is provided in the cap 30, the mucosal surface is sucked and the mucous membrane is damaged, or the suction operation cannot be smoothly performed. In particular, when the brush 33 is provided, suction while being scraped off by the brush 33 can be performed and the suction force can be adjusted to some extent, so that cleaning of the oral cavity can be performed more efficiently. In the case where the wall portion 32 is provided, the surface surrounded by the tip of the wall portion 32 is a flat opening having no curvature, so that the flat opening is efficiently in close contact with the target site, and a high suction force is obtained. It can be demonstrated.
