DETAILED DESCRIPTION

[0118] The invention will now be described in more detail with reference to the attached drawings. Like parts in different embodiments may be described using the same reference numerals.

[0119] In FIGS. 1 to 8, a first embodiment of the invention is illustrated. As shown in FIG. 1, the suction device has a suction tube or suction line 101 which can be connected to a vacuum source in order to create a negative pressure inside the suction tube. The suction tube 101 has an exposed part 102 which is visible. The suction tube 101 extends into the absorption body 111 of the suction device with a suction part 103 embedded in the absorption body (not visible in FIG. 1). The absorption body 111 consists of a main part 112, and optionally of an extension part 113. The main part 112 is arranged to be placed at the user's bottom of the mouth between the lower part of the lower jaw and the tongue.

[0120] The extension part 113 is arranged to extend backward from the main part 112 towards the patient's throat. The exposed part 102 of the suction tube is conventionally bent to easily be fixed around the patient's chin. The suction device is shown in FIG. 2 in a sectional view of its length extension whereby suction part 103 of the suction tube 101 is visible. In this example, exposed part 102 of the suction tube is shown. The suction part 103 may alternatively be jointed to the juncture between the suction part 103 and the exposed part 102. The suction part 103 is equipped with multiple holes 104 which connect the tubes inner part with the covering absorption body. In this example, the absorption body is smoothly arch-shaped, but since the suction device is made of elastic deformable material the device can adapt to other shapes in order to fit the patient's oral cavity and the bottom of the mouth, in particular.

[0121] FIG. 3, which is a sectional view along line III-III in FIG. 2, shows that the absorption body in the lateral direction has a non-circular outer contour with a base 112b and a top 112t, whereby the base 112b is broader than the top 112t, and shows a triangular-like cross section. The suction part 103 of the suction tube 101 is centrally located in the absorption body. Alternatively to the illustration, this part can be located in other positions in the absorption body, e.g. in an asymmetric placement. Also, the outer contour may be different than the exemplified. Examples of different contours are shown in FIGS. 10 to 14.

[0122] FIGS. 4 and 5 schematically show the fluid flow through the suction device. Saliva and water enter the absorption body 111 from mucous membranes and from other places in the oral cavity, where the fluid accumulates, as indicated by arrows A. The suction tube 101 is connected to vacuum whereby underpressure is generated inside its suction part 103. By capillary action the fluid entering the absorption body 111 is absorbed in the direction of the suction part 103, as indicated by arrows B. Through the vacuum the fluid is absorbed by the suction tube according to the arrow C, and is removed according to arrow D. FIGS. 6 and 7 illustrate the suction device in place at the bottom of the mouth between the lower part of the lower jaw 116 and the tongue 117.

[0123] FIG. 8 illustrates the suction device placed in a slightly displaced position in relation to FIG. 6. This positioning can be beneficial in filling and cementation of prosthetic constructions in the front part of the patient's mouth. Since the suction device is made of elastic deformable and adjustable material, the suction device can be bent and be placed at the bottom of the mouth beside the lower part of the lower jaw by the incisors and extends back toward the lower part of the lower jaw by the premolars and molars on the right and/or left side.

[0124] The suction tube 101 is preferably made of extruded plastic and if needed also includes an integrated wire that allows the operator to reshape the tube if necessary. The suction tube has a prefabricated shape and size that allows it to be easily placed at the bottom of the mouth and at the same time to cover the lower part of the lower jaw for a secure fixation.

[0125] The suction tube may have a round shape or an oval shape, which is even more easy to bend. Also, the wire may be flat, having a softer spring characteristic in its flat direction. Both may be adapted to the users needs.

[0126] The suction part 903 of the suction tube can, as illustrated in FIG. 9, be provided with holes of different size and shape. The holes 904a, 904b, and 904c are circular with different diameters where the holes 904a closest to the exposed part of the suction tube or line portion are the smallest. The holes 904d and 904e are elongated.

[0127] The absorption body 111 is made of suitably elastically deformable material which enables fluid transport through the body, preferably foam plastic with open cells. It is also possible to use other soft materials that have capillary action like, for example, cotton fibers, various textile fibers, synthetic fibers, mull, lint or gauze, preferably covered by a mesh, and the like.

[0128] In the embodiment example illustrated in FIGS. 15 and 16, the suction device includes a secondary absorption body 618 beyond the main absorption body 612, 613. The secondary absorption body 618 is arranged to be placed at the Glandula Parotis excretory duct and is connected with the main absorption body via a connecting line 605. The main absorption body is arranged for an application as illustrated in FIG. 6. Via the secondary absorption body 618, saliva from the Glandula Parotis is directly absorbed where it is generated and via the main absorption body transferred to the suction tube 602. The connecting line 605 can advantageously be used as an extension of the suction part of the suction tube, but an arrangement on an additional line of the exposed part 102 of the suction tube is also possible or an arrangement as an additional line to the suction part 103 before the transition to an extension part.

[0129] In the embodiment example illustrated in FIG. 17, the suction device comprises a tongue protection 714. The tongue protection aims to block the tongue and so protect the tongue from rotating instruments during the dental treatment and also to prevent the tongue from touching the tooth or teeth in any critical area which may cause a contamination with saliva when performing different filling and/or cementation of prosthetic constructions. FIG. 17 illustrates an embodiment, where the tongue protection 714 is arranged in an extension 705 of the suction tube 702, but in another (not illustrated) embodiment, the tongue protection may be arranged on one sidearm of the exposed suction tube 702. In a further (not illustrated) embodiment, the suction device includes two tongue protections, one arranged as illustrated in FIG. 17, and one arranged on one sidearm of the exposed suction tube 702. The tongue protection can be made of elastically deformable material. Thus, the tongue protection can be bent, as illustrated with arrow H in FIG. 18, along line I, and therefore effectively separates the tongue from the operation, while also allowing the assisting personnel to obtain full access and insight for required interventions and complementary removal of water and saliva.

[0130] In one embodiment, the tongue protection is made of a material which can be broken off, e.g. along line 715, in order to adjust the fitting and placement in the oral cavity and also in order to enable an increased access and insight while the ability to protect the tongue during treatment is retained.

[0131] Furthermore, the tongue protection may be arranged in relation to the suction tube's 702 suction part 703 and the absorption body 712, as illustrated by arrows E, F and G in FIG. 17.

[0132] In a further (not illustrated) embodiment, the tongue protection has an absorption capacity. This absorption capacity can either be provided in the case that the tongue protection is made of absorbable material or when the tongue protection is equipped with a suction tube which is connected with the suction device and its absorption body.

[0133] FIG. 19 shows another embodiment of the invention. According to this embodiment, the absorption body 711 is formed such that it is noncircular, with a base and a top, whereby the base 741 is broader than the top 740. The general form corresponds to an egg, however with a waist such that having concave parts 719 separating the top portion 740 and the base portion 741.

[0134] According to this embodiment, a huge suction buffer is provided which is intended to at least partially fill out the space under the patient's tongue. Also, with such a huge buffer, the desired pump action created by the force exerted by the tongue is improved.

[0135] The absorption body 711 is made by an open-porous foam with a high elasticity, i. e. a soft open foam. This foam, according to the shown embodiment, is covered by a silky mesh which is also open-porous, to let the fluid pass, and is pleasant and comfortable to the patient. Alternatively, it can be closed-porous to block fluids.

[0136] FIG. 21 shows another embodiment of the inventive dental suction arrangement.

[0137] A suction part 703 passes through the top portion 740. It has a plurality of suction holes 704a, 704b and 704c which are distributed unevenly and with different diameters and forms, all over suction part 703.

[0138] Preferably, the suction part 703 extends in the center of the top portion 740. In a different embodiment it may extend eccentrically, in order to increase the suction power at one side of absorption body 711.

[0139] According to this embodiment, a tongue holder 714 is arranged at the end of a second suction line 705. The absorption body 711 is arranged between the second suction line 705 and first suction line 702. It comprises a suction part 703 with a plurality of suction holes 704.

[0140] As may be taken from the arrows C, D and E, all parts of this embodiment may be easily adjusted and bent according to the needs. Generally, it is preferred to have the second suction line 705 being bent by about 150 to 180 degrees and also the first suction line 702 bent several times.

[0141] The idea is to have the absorption body 703 being arranged as low as possible under the patient's tongue in the bottom of the mouth, close to glandolar submandibularis and glandouar sublingualis, and the tongue holder 711 extending upwardly from there and pressing the tongue obliquely upwardly and away from the jaw.

[0142] The first suction line 702, on the other hand, will cross over the canines or incisors of the patient and leave the mouth to be attached to a suction source like a vacuum pump.

[0143] By such an arrangement, both the absorption body 703 is pressed down, and the tongue holder 711 is pressed upwardly. Thus, it is preferred to have a certain section in the second suction line which should be bendable, in order to adapted to the patient's needs.

[0144] Another embodiment is shown in FIG. 21. This embodiment comprises a suction line 702 and a so-called full jaw absorption body 703. This absorption body is essentially shaped-shaped and comprises a suction part with suction holes even though this is not shown in FIG. 21. It is intended to be placed under the tongue and the suction line 702 is of a flexibility such that it may be bent at a hinge area 725, to have this essentially U-shaped absorption body inserted into the oral cavity either such that the suction line 702 is arranged on the left side or on the right side.

[0145] In another embodiment which is not shown, an additional tongue holder is arranged at the end 726 of the absorption body 703. The form thereof may be similar to the form shown in FIG. 20, and a second suction line may be provided between the tongue holder 714 and the end 726.

[0146] In FIG. 22, another embodiment of the invention is illustrated. As shown in FIG. 22, the suction device has a suction tube or suction line 101 which can be connected to a vacuum source in order to create a negative pressure inside the suction tube. The suction tube 101 has an exposed part 102 which is visible. The suction tube 101 extends into the absorption body 111 of the suction device with a suction part 103 embedded in the absorption body (not visible in FIG. 22). The absorption body 111 which surrounds the suction part 103 is arranged to be placed at the user's bottom of the mouth between the lower part of the lower jaw and the tongue.

[0147] The absorption body 111 thus follows the oral side of the dental arch. The absorption body is essentially U-shaped, or, to be more specific, parabolic. The form of the absorption body 111 is mainly determined by being adjacent or close-fitting to the lower part of the lower jaw. On the other hand, the suction part 103 extends through the absorption body 111. The suction part 103 has a greater stiffness than the absorption body 111 which absorption body 111 comprises preferably an open porous foam which, in an advantageous development, is covered by a silky mesh. The suction tube or suction line 101 which also comprises the suction part 103 is made from deformable plastic, and the suction part 103 comprises holes through which saliva or similar fluids may be sucked away.

[0148] In this example, the exposed part 102 of the suction tube 101 is shown. The suction part 103 may alternatively be joined to a juncture 105 between the suction part 103 and the exposed part 102. This is shown in FIGS. 23 and 24. The junction 105 comprises a sleeve 106 formed on the exposed part 102 and a plug 107 formed on the suction part 103.

[0149] The suction part 103 is equipped with multiple holes 104 which connect the tubes inner part with the covering absorption body. In this example, the absorptions body is arch-shaped or parabolic shaped, but since the suction device is made of elastic deformable material the device is adapted to fit into the patient's oral cavity and the bottom of the mouth in particular.

[0150] FIG. 25, which is a sectional view along line III-III in FIG. 23, shows that the absorption body in the lateral direction has a non-circular outer contour with a base 112b and a top 112t, whereby the base 112b is broader than the top 112t, and shows a triangular-like cross section. The suction part 103 of the suction tube 101 is centrally located in the absorption body. Alternatively to the illustration, this part can be located in other positions in the absorption body, e.g. in an asymmetric placement. Also, the outer contour may be different than the exemplified.

[0151] The suction line 101 is connected to a vacuum source which is not shown. Based on this vacuum, there is a fluid flow through the suction device 101. Saliva and water enter the absorption body 111 from mucous membranes and from other places in the oral cavity, where the fluid accumulates. The suction tube 101 is connected to vacuum whereby underpressure is generated inside its suction part 103. By capillary action the fluid entering the absorption body 111 is absorbed in the direction of the suction part 103. Through the vacuum the fluid is absorbed by the suction tube, and is removed.

[0152] Since the suction device 101 is made of elastic deformable and adjustable material, the suction device can be bent and be placed at the bottom of the mouth beside and along the lower part of the lower jaw by the incisors and extend back toward the lower part of the lower jaw by the premolars and molars on the right and/or left side.

[0153] The suction tube 101 is preferably made of extruded plastic and if needed also includes an integrated wire that allows the operator to reshape the tube if necessary. The suction tube has prefabricated shape and size that allows it to be easily placed at the bottom of the mouth and at the same time to cover the lower part of the lower jaw for a secure fixation.

[0154] The suction tube may havein a cross-sectional viewa round shape or an oval shape which is even more easy to bend. Also, the wire may be flat, having a softer spring characteristic in its flat direction. Both may be adapted to the users needs.

[0155] The suction part 103 of the suction tube can, be provided with holes 104 of different size and shape. Some holes are circular with different diameter where the holes 104 closest to the exposed part of the suction tube or line are portion are the smallest. Other holes are elongated.

[0156] The absorption body 111 is made of suitably elastically deformable material which enables fluid transport through the body, preferably foam plastic with open cells. It is also possible to use other soft materials that have capillary action like for example, cotton fibers, various textile fibers, synthetic fibers, mull, lint or gauze, preferably covered by a mesh, and the like.

[0157] In the embodiment example illustrated in FIG. 26 the suction device comprises a tongue protection 114. The tongue protection aims to block the tongue and so protect the tongue from rotating instruments during the dental treatment and also to prevent the tongue from touching the tooth or teeth in any critical area which may cause a contamination with saliva when performing different filling and/or cementation of prosthetic constructions. FIG. 26 illustrates an embodiment, where two tongue protections 114 are arranged on both end sides of the absorption body 111. In this embodiment they are connected to the suction part 103 and extend through the foam of the absorption body 111, but in another embodiment, the tongue protection 114 may be arranged on one sidearm of an exposed suction tube 120. In the present embodiment, the suction device 101 includes two tongue protections, one arranged on one sidearm 120 an one arranged on the exposed suction tube 102. Two tongue protections can be made of elastically deformable material. Thus, the tongue protection can be bent, and therefore effectively separate the tongue from the operation, while also allowing the assisting personal to obtain full access and insight for required interventions and complementary removal of water and saliva.

[0158] In one embodiment, the tongue protection is made of a material which can be broken off, in order to adjust the fitting and placement in the oral cavity and also in order to enable an increased access and insight while the ability to protect the tongue during treatment is retained.

[0159] Furthermore, the tongue protection may be arranged in relation to the suction part 103 of the suction tube 101 and the absorption body 111.

[0160] In a further (not illustrated) embodiment, the tongue protection has an absorption capacity. This absorption capacity can either be provided in case the tongue protection is made of absorbable material or when the tongue protection is equipped with a suction tube which is connected with the suction device and its absorption body.

[0161] As may be taken from FIG. 26 (and FIG. 22), the suction tube 101 or suction line 101 extends upwardly from the absorption body 111. It is intended to transverse the lower jaw distal from the last molar, there crossing a tooth-free and gingival portion of the lower jaw. This part is designated as transverse part 115 of the suction tube 101. The suction line 101 then enters the user's mouth downwardly along the user's chin. The suction line comprises a counter bow 116 which is intended to be pressed against the user's chin from its lower side such as to keep the absorption body 111 in place.

[0162] Another embodiment is shown in FIG. 27. It has a plug 107 which is intended to be attached to a sleeve 106 of the exposed part 102 of a suction line 101.

[0163] The absorption body 111 is essentially parabolic or essentially U-shaped. Contrary to the remaining embodiments, this embodiment comprises a tongue shield 117 which is intended to keep the tongue at its regular position and to avoid tongue play which would unduly disturb surgery by the dentist.

[0164] The tongue shield 117 may be made of any suitable material and also may be very elastic. The tongue shield may be attached to the absorption body 111 but also to the suction part 103 running through the absorption body 111.

[0165] A back view, i. e. a distal view, of this embodiment is shown in FIG. 28.

[0166] FIG. 29 shows another embodiment comprising a U-shaped or parabolic shaped absorption body 111 and a suction line 101, with its exposed part 102 being shown.

[0167] Contrary to other embodiments, there is an exposed suction tube 120 extending from the other hand of the absorption body 111. This exposed part is intended to also comprise a transverse part 115. The exposed part 120 is shaped in a suitable manner to keep the absorption body 111 in place by bi-lateral fixation under the chin. The suction line 101 exiting from the mouth may have any suitable form.

[0168] Another example is shown in FIG. 32. With this example, the counter bow 116 is intended to be arranged centrally under the user's chin, thus to make the downward pressing force of the suction line towards the absorption body 111 having a less unilateral attack angle.

[0169] A similar arrangement may be taken from FIG. 33. In this arrangement, a junction 105 comprises with a sleeve 106 and a plug 107. Contrary to FIGS. 2a and 2b, the sleeve 106 with this embodiment is arranged close to the absorption body 111.

[0170] In FIG. 34, another embodiment of an absorption body 111 is shown. This embodiment comprises a tongue shield 114 which extends upwardly from the absorption body 111 and has a parabolic shape intended to keep away the tongue from the dental arch.

[0171] In FIG. 35, the same as 11A but with the extension parts shown 122 as a part of the foam body and 123 as a separate connected part of mesh or fibres or similar.

[0172] Advantageously, at least one protection shield is used which is attached to the absorption body 111, the suction part 103 and/or the exposed part 102 of the suction line 101, or a free end thereof. The protection shield 114 or the protection shields 114 may be bendable and can be brought into any desired form. They may have at least one breaking line, and/or may be light cure shields.

[0173] FIG. 36 shows another embodiment which comprises a moisture sensor 118 which is attached to above absorption body 111 or mounted within the absorption body 111 which is shown schematically in FIG. 12. There are supply lines 119 running through the suction line 101 for electrical connection of the moisture sensor 118.

[0174] FIG. 37 shows another embodiment which comprises a moisture sensor 118 which is attached to above absorption body 111 or mounted within the absorption body 111 which is shown schematically in FIG. 37. These sensors are transmitting wireless to a suitable device, e.g. the vacuum-system.

[0175] From FIG. 38, it may be taken that the absorption body 111 comprising the suction part 103 may be bent to any suitable form, within the anatomy as desired.

[0176] If needed it may be also be shorted by cutting off its ends or at least one end thereof.

[0177] The absorption body 111 is made by open-porous foam with a high elasticity, i.e. a soft open foam. This foam, according to the shown embodiment, is covered by a silky mesh which is also open-porous, to let the fluid pass, and is pleasant and comfortable to the patient. Alternatively, it is closed-porous to block fluids.

[0178] FIG. 39 shows another embodiment of the inventive dental suction arrangement.

[0179] A suction part 703 passes through the top portion 740. It has a plurality of suction holes 704a, 704b and 704c which are distributed uneven and with different diameters and form all over the suction part 703.

[0180] Preferably, the suction part 703 extends in the center of the top portion 740. In the different embodiment it may extend eccentrically, in order to increase the suction power at one side of the absorption body 711.

[0181] The idea is to have the absorption body 711 being arranged as low as possible under the patient's tongue in the bottom of the mouth, close to glandolar submandibularis and glandolar sublingualis, and a tongue holder extending upwardly from there and pressing the tongue obliquely upwardly and way from the jaw.

[0182] Another embodiment is shown in FIG. 40. This embodiment comprises a suction line 702 and a so-called full jaw absorption body 703. This absorption body is essentially U-shaped and comprises a suction part with suction holes even this is not shown in FIG. 40. It is intended to be placed under the tongue and the suction line 702 is of a flexibility such that it may be bent at a hinge area 725, to have this essentially U-shaped absorption body being inserted into the oral cavity either such that the suction line 702 is arranged on the left side or on the right side.

[0183] According to the invention, the absorption body 111 is placed under the tongue, following the essential parabolic shape of the dental arch at the oral side. The absorption foam body is of a open porous foam such that it may be compressed between the tongue and the dental arch to up to 85 volume percent. A transverse region 115 of the suction line 101 is provided which extends essentially horizontal for crossing the jaw after the last molar on one side of the mouth or on both sides of the mouth The transverse portion 115 is caught between upper and lower jaw, thus indirectly fixing the absorption body 111. The absorption body 111 is fixed especially in occlusion but is pressed downward even before occlusion by the flexible suction line 101.

[0184] For further improving the fixture, a counter bow 116 is provided in the suction line 101 which is intended to further fix it under the user's chin.

[0185] According to FIG. 41, this counter bow 116 may be provided with an additional foam body 115 for improving user's comfort.

[0186] A further embodiment of the absorption body 111 is shown in FIGS. 42 and 43. In this embodiment, the absorption body is provided with a silky mesh 126 and 127 on both the vestibular side and the oral side.

[0187] Thus, as may be taken from FIG. 43, the suction force is focused both on the upper side and the lower side of the absorption body 111 which is beneficial to improve suction efficiency.

[0188] Another embodiment of the invention is shown in FIG. 44. This embodiment is shown, for the purpose of clarity, before occlusion, i.e. with antagonists still being separate from another. Yet it is intended to be functional in occlusion, with the transverse portion 115 extending distal from or behind the last molar 130.

[0189] The suction line 101, when exiting the transverse portion 115, is bent upwardly and is provided with an additional foam body 135 which is intended to be arranged vestibular of the antagonist 131. From this area, the suction line 101 runs downwardly and form a counter bow 116 as shown in other embodiments.

[0190] The invention has been described in relation to the current understanding of which are the most practical and preferred embodiments, but it is recognized that the invention is not limited to the described embodiments; several variations and modifications are possible. The scope of the invention is therefore exclusively defined by the attached patent claims.
