Toothbrushing aids and their usage

Abstract

This toothbrushing aid allows the caregiver to brush teeth stably with both hands free after being placed between the teeth, reducing the burden on both the person being assisted and the caregiver, while also providing a highly accurate reduction in areas that are missed during brushing. [Solution] The synthetic resin toothbrushing aid 2 has a paired configuration consisting of a first toothbrushing aid 4 for the left side and a second toothbrushing aid 6 for the right side. The first toothbrushing aid 4 has a roughly U-shaped main body 4a that is inserted from one corner of the mouth (in this case, the left side) and attached so as to sandwich the cheek from the inside and outside, and a biting part 4b that is integrally formed at the inner end of the main body 4a (arrow MI side) and is positioned between the teeth. When the first toothbrushing aid 4 is attached, both hands of the caregiver performing the toothbrushing of the person being cared for, such as an infant, become free, and the teeth on the opposite side from where the first toothbrushing aid 4 is attached can be brushed easily and stably.

Description

Technical Field

[0001] The present invention relates to a toothbrushing aid for assisting toothbrushing of infants, care recipients, etc., and a method of using the same.

Background Art

[0002] Infants, care recipients, etc. have difficulty brushing their teeth properly on their own and need assistance from caregivers such as parents and nurses. Especially in the case of infants, there are situations where they do not open their mouths or bite the toothbrush, making it difficult to brush their teeth. As a countermeasure, an oral opener is known. This type of oral opener has a structure that forcibly opens the mouth so as not to come off, and there is a concern that it may have an adverse effect on the jaw and teeth, and it is inevitable to cause pain to the care recipient such as an infant. In addition, there is a problem that it requires time and skill for the caregiver to put it on.

[0003] Patent Document 1 discloses a toothbrushing aid including a tooth-biting part formed of a flexible material such as silicone resin, a rod-shaped intermediate part that extends straight from the tooth-biting part and then bends at a right angle to come out outside the mouth, and an elliptical grip part formed at the outer end of the intermediate part. While holding and supporting the grip part with one hand with the tooth-biting part bitten between the teeth, the teeth on the side where the tooth-biting part is not bitten are brushed with the other hand.

Summary of the Invention

Problems to be Solved by the Invention

[0005] In the configuration described in Patent Document 1, one hand is restrained to hold the grip, so the caregiver must brush with the other hand. As a result, the brushing motion is unstable, and if the person being cared for, such as an infant, shakes their head vigorously, the tooth-cleaning part easily comes off because the grip is held (fixed in position) by the caregiver, and it takes time to get them to bite down again. Consequently, the brushing time inevitably tends to be longer, and it is undeniable that this increases the burden on both the person being cared for and the caregiver. In addition, for the caregiver, the hand used to brush the teeth on either side of the person's mouth may not be their dominant hand, which can lead to unstable brushing motions and missed spots.

[0006] The present invention has been made in view of the above-mentioned points, and its purpose is to provide a toothbrushing aid and a method of using the same that, after being placed between the teeth, allows the caregiver to brush teeth stably with both hands free, thereby reducing the burden on both the person being assisted and the caregiver, and reducing missed spots with high precision. [Means for solving the problem]

[0007] To achieve the above objective, the toothbrushing aid (2) of the present invention is characterized by having a substantially U-shaped main body portion (4a, 6a) that is attached so as to sandwich the cheek (8b), and a biting portion (4b, 6b) that is integrally formed at the inner mouth end of the main body portion (4a, 6a) and positioned between the teeth.

[0008] With the toothbrushing aid according to the present invention, both hands of the caregiver are free after attachment, making it possible to brush the teeth of the person being cared for easily and with high precision.

[0009] Furthermore, in the toothbrushing aid (2) described above, the main body (4a, 6a) may be configured to have a roughly U-shaped gap on the opening side so as to elastically grip the cheek (8b). This allows the aid to be attached by utilizing the deformability of the cheek and prevents displacement after attachment.

[0010] Furthermore, the toothbrushing aid (2) described above may have a configuration in which a first gripping piece (4c, 6c) is integrally formed on the outer end of the main body (4a, 6a) and is used to press the main body (4a, 6a) against the cheek (8b) for attachment. This allows the first gripping piece to be grasped for attachment, making the attachment process easier.

[0011] Furthermore, the toothbrushing aid (2) described above may have a configuration in which a second gripping piece (4d, 6d) is integrally formed on the roughly U-shaped bottom side of the main body (4a, 6a) on the oral side, and when gripped together with the first gripping piece (4c, 6c), it is possible to widen the opening side of the main body (4a, 6a) by elastic deformation. This eliminates snagging during attachment and allows for smooth attachment without causing discomfort to infants.

[0012] Furthermore, in the toothbrushing aid (2) described above, the biting parts (4b, 6b) may be formed in a columnar shape with a circular or elliptical cross-section. This allows the user to bite down on the tooth without damaging it.

[0013] Furthermore, the toothbrushing aid (2) described above may be configured such that a mirror member (18) is provided on the mouth-side of the main body (4a, 6a) so that the toothbrushing situation can be viewed from the back side of the person being assisted (20) having their teeth brushed. This allows for easy toothbrushing while stably supporting the person being assisted, such as an infant, and while giving the person being assisted a sense of security.

[0014] Furthermore, in the toothbrushing aid (2) described above, the mirror member (18) may be detachably attached to the main body (4a, 6a). This allows the mirror member to be added later, eliminating bulkiness when attached and making attachment easier.

[0015] Furthermore, the toothbrushing aid (2) described above has a paired configuration consisting of a first toothbrushing aid (4) whose biting portion (4b) is formed in the shape of an elliptical column in cross-section, and a second toothbrushing aid (6) whose biting portion (6b) is formed in the shape of a circular column in cross-section, wherein the major axis diameter (D1) of the biting portion (4b) of the first toothbrushing aid (4) is larger than the outer diameter (D2) of the biting portion (6b) of the second toothbrushing aid (6), and the minor axis diameter (D3) is smaller than the outer diameter (D2) of the biting portion (6b) of the second toothbrushing aid (6). According to this, by utilizing the difference in dimensions between the gripping portion of the first toothbrushing aid and the gripping portion of the second toothbrushing aid, the second toothbrushing aid can be smoothly attached to the opposite side after brushing the teeth on the opposite side of the first toothbrushing aid. Subsequently, by rotating the first toothbrushing aid so that the gripping portion has a shorter axis diameter, the first toothbrushing aid can be easily removed, and the area can be brushed after removal.

[0016] Furthermore, the toothbrushing aid (2) described above includes a first toothbrushing aid (4) having a roughly U-shaped main body (4a) that is attached to sandwich the cheek (8b), and a biting part (4b) integrally formed at the inner end of the main body (4a) and positioned between the teeth, wherein the biting part (4b) is formed in the shape of an elliptical columnar cross-section, and a second toothbrushing aid (6) having a roughly U-shaped main body (6a) that is attached to sandwich the cheek (8b), and a biting part (6b) integrally formed at the inner end of the main body (6a) and positioned between the teeth, wherein the biting part (6b) is formed in the shape of a circular columnar cross-section, and the first The long axis diameter (D1) of the biting portion (4b) of the toothbrushing aid (4) is set to be larger than the outer diameter (D2) of the biting portion (6b) of the second toothbrushing aid (6), and the short axis diameter (D3) is set to be smaller than the outer diameter (D2) of the biting portion (6b) of the second toothbrushing aid (6). The first toothbrushing aid (4) is attached so that the biting portion (4b) bites with the long axis diameter (D1), and the side of the upper and lower teeth where no toothbrushing aid is present is brushed. The second toothbrushing aid (6) is then attached to the side that has been brushed, and the first toothbrushing aid (4) is then rotated approximately 90 degrees and pulled out, and the other side of the upper and lower teeth is then brushed. The second toothbrushing aid can be smoothly attached while the first toothbrushing aid is attached, and the first toothbrushing aid can be easily pulled out while the second toothbrushing aid is attached, so that both sides of the teeth can be easily brushed alternately. [Effects of the Invention]

[0017] According to the present invention, after the device is placed between the teeth, the caregiver's hands are free, allowing for stable brushing of the teeth. This reduces the burden on both the person being cared for and the caregiver, and also reduces missed spots with high precision. [Brief explanation of the drawing]

Mode for Carrying Out the Invention

[0019] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0020] [First Embodiment] The first embodiment will be described with reference to FIGS. 1 to 6. As shown in FIG. 1, the toothbrushing aid 2 according to the present embodiment has a pair configuration including a first toothbrushing aid 4 and a second toothbrushing aid 6.

[0021] The first toothbrushing aid 4 is integrally molded from synthetic resin and has a roughly U-shaped main body 4a that is inserted from one corner of the mouth (in this case, the left side) and attached so as to sandwich the cheek from the inside and outside, and a biting part 4b integrally formed at the inner end of the main body 4a (arrow MI side) and positioned between the teeth. The main body 4a has a roughly U-shaped gap g1 on the open side so as to sandwich the cheek with elastic force. The first toothbrushing aid 4 also has a first gripping piece 4c integrally formed at the outer end of the main body 4a (arrow MO side) for pushing the main body 4a into the cheek for attachment, and a second gripping piece 4d integrally formed on the roughly U-shaped bottom side on the outer side of the main body 4a, which, when gripped together with the first gripping piece 4c, can widen the open side of the main body 4a by elastic deformation. The biting part 4b is formed in a columnar shape with an elliptical cross-section. The bottom side of the roughly U-shaped main body 4a is wider than the opening side, and the first gripping piece 4c is formed to curve gently and extend outward to facilitate insertion into the corner of the mouth.

[0022] Similarly, the second toothbrushing aid 6 is integrally molded from synthetic resin and has a roughly U-shaped main body 6a that is inserted from one corner of the mouth (in this case, the right side) and attached so as to pinch the cheek, and a biting part 6b integrally formed at the inner end of the main body 6a (arrow MI side) and positioned between the teeth. The main body 6a has a roughly U-shaped gap g2 (=g1) on the open side so as to elastically pinch the cheek. The second toothbrushing aid 6 also has a first gripping piece 6c integrally formed at the outer end of the main body 6a (arrow MO side) for pushing the main body 6a into the cheek for attachment, and a second gripping piece 6d integrally formed on the roughly U-shaped bottom side on the outer side of the main body 6a, which, when gripped together with the first gripping piece 6c, can widen the open side of the main body 6a by elastic deformation. The biting part 6b is formed in a columnar shape with a circular cross-section. The bottom side of the roughly U-shaped main body 6a is wider than the opening side, and the first gripping piece 6c is formed to curve gently and extend outward to facilitate insertion into the corner of the mouth.

[0023] In Figure 1, the second toothbrushing aid 6 is shown upside down compared to its actual use in order to clearly distinguish between the biting portion 4b and the biting portion 6b. In other words, the second toothbrushing aid 6 is actually used with the biting portion 6b facing the biting portion 4b of the first toothbrushing aid 4. The first toothbrushing aid 4 and the second toothbrushing aid 6 have a so-called reversible shape, meaning they can be attached to either the left or right side of the mouth by reversing their front and back sides.

[0024] As shown in Figure 2, the tip of the biting portion 4b of the first toothbrushing aid 4 has an arc-shaped chamfered portion 4b-1 to prevent injury to the tongue, and the tip of the biting portion 6b of the second toothbrushing aid 6 also has a similar chamfered portion 6b-1. The major axis diameter D1 of the elliptical biting portion 4b of the first toothbrushing aid 4 is larger than the outer diameter D2 of the circular biting portion 6b of the second toothbrushing aid 6, and the minor axis diameter D3 is smaller than the outer diameter D2 of the biting portion 6b of the second toothbrushing aid 6. In other words, the relationship is D1 > D2 > D3.

[0025] Figure 3 shows how to attach the first toothbrushing aid 4 and the second toothbrushing aid 6. Here, an example of attachment from the front of the person being assisted's face is shown. As shown in Figure 3(a), the caregiver grasps the first gripping piece 4c of the first toothbrushing aid 4 with the thumb F1 and index finger F2 of one hand (right hand in this case), moves the first toothbrushing aid 4 with the opening side of the main body 4a toward the corner of the mouth 8a, and attaches it to the cheek 8b. The cheek 8b becomes thicker toward the back of the face, but because of the deformation of the thickness, it can be attached with little resistance even if the opening side of the roughly U-shaped main body 4a is narrow, and after attachment the opening side fits the cheek 8b with a weak elastic force. "Weak elastic force" means a clamping pressure that does not easily cause the first toothbrushing aid 4 to shift position relative to the cheek 8b. In other words, the opening side of the main body 4a is lightly pressed into the cheek 8b from both inside and outside the mouth.

[0026] To attach the first toothbrushing aid 4 to the cheek 8b without resistance, as shown in Figure 3(b), the first pinching piece 4c is pinched with the index finger F2 and the second pinching piece 4d is pinched with the thumb F1, bringing them together. This causes the outer side of the main body 4a to bend outward due to elastic deformation, widening the roughly U-shaped opening. Attaching it to the cheek 8b in this state allows for smooth attachment without snagging. This is particularly effective for infants, as snagging can cause them to cry. After attaching it to the cheek 8b in the state shown in Figure 3(b), releasing the pinching motion causes the first toothbrushing aid 4 to attach to the cheek 8b with a weak elastic force as the main body 4a returns to its original position. The same applies to the second toothbrushing aid 6.

[0027] Referring to Figures 4 to 6, the method of using the paired toothbrushing aid 2 will be explained. For clarity, the upper and lower dental arches are schematically shown as horseshoe shapes. First, as shown in Figure 4(a), the caregiver holds the first toothbrushing aid 4 in front of the person being cared for, and, for example, timing it with the person being cared for to open their mouth, attaches the biting part 4b to the cheek 8b so that it bites on the long axis between the posterior teeth of the upper dental arch 10 and the lower dental arch 12. This attachment operation is performed with one hand (in this case, the right hand) of the caregiver, and after attachment, the first toothbrushing aid 4 is positioned with almost no vertical or horizontal displacement. Therefore, both of the caregiver's hands are free.

[0028] After attaching the first toothbrushing aid 4, the caregiver brushes the area 14B of the upper and lower teeth 10 and the area opposite to where the first toothbrushing aid 4 is attached, using a toothbrush. In this case, the caregiver has both hands free and can brush with their dominant hand. There is nothing in area 14B that would hinder brushing, so normal brushing can be performed. The caregiver's other hand, now free, can be used for purposes such as holding the infant's head still, thus enabling stable support for the person being cared for.

[0029] After brushing area 14B, as shown in Figure 4(b), attach the second toothbrushing aid 6, which is prepared on hand, to the cheek 8b so that the biting part 6b is bitten into in the posterior interdental space on the opposite side of where the first toothbrushing aid 4 is attached to the upper teeth 10 and lower teeth 12. In this case, the second toothbrushing aid 6 is used with the front and back reversed compared to the state shown in Figure 1. As described above, the major axis diameter D1 of the biting part 4b of the first toothbrushing aid 4 is larger than the outer diameter D2 of the circular biting part 6b of the second toothbrushing aid 6, so the biting part 6b of the second toothbrushing aid 6 can be positioned between the teeth of the upper teeth 10 and lower teeth 12 without resistance.

[0030] In the configuration described in Patent Document 1, when brushing the opposite side, it is necessary to remove the toothbrushing aid, change the posture in an unfamiliar way, and then reattach it, which is troublesome as the person being assisted has to open their mouth again and bite down on the teeth-clenching part. In contrast, in the toothbrushing aid 2 according to this embodiment, the first toothbrushing aid 4 remains on one side, and the second toothbrushing aid 6 is attached with the upper teeth 10 and lower teeth 12 open, so there is no need to open the mouth again, and since it takes advantage of the difference in size between the biting parts 4b and 6b, attachment is also extremely easy.

[0031] From the state shown in Figure 4(b), rotate the first toothbrushing aid 4 upward by approximately 90 degrees as shown in Figure 5(a), so that the minor axis diameter D3 of the biting portion 4b is at the top and bottom, as shown in Figure 5(b). The rotation of the first toothbrushing aid 4 is made possible by the flexible thickness deformation of the cheek 8b. As described above, the minor axis diameter D3 of the biting portion 4b is smaller than the outer diameter D2 of the circular biting portion 6b of the second toothbrushing aid 6, so the biting portion 6b of the second toothbrushing aid 6 acts as a jack-like support, releasing the biting portion 4b of the first toothbrushing aid 4 from the interdental biting pressure, making it possible to withdraw it. In this state, withdraw the first toothbrushing aid 4 as shown in Figure 6. After that, brush the teeth in the area 14A where the first toothbrushing aid 4 was withdrawn.

[0032] [Second Embodiment] A second embodiment will be described with reference to Figures 7 and 8. Parts identical to or considered identical to those in the first embodiment are indicated by the same reference numerals, and descriptions of the configuration and function already given will be omitted as appropriate.

[0033] As shown in Figure 7, in the toothbrushing aid 16 according to this embodiment, a mirror member 18 is detachably provided on the mouth-side of the substantially U-shaped main body 6a, allowing the user to see the toothbrushing process from the back side of the person being assisted. The toothbrushing aid 16 has a general configuration that is the reverse of the front and back of the second toothbrushing aid 6, and includes a main body 6a, a biting portion 6b, a first gripping piece 6c, and a cylindrical portion 6e formed in place of the second gripping piece 6d.

[0034] The mirror member 18 comprises a pivot shaft 18a inserted into the cylindrical portion 6e, a cylindrical portion 18b formed at the upper end of the pivot shaft 18a, an arm portion 18c extending horizontally from the cylindrical portion 18b and bending, and a convex mirror 18d attached to the tip of the arm portion 18c. The diameter of the pivot shaft 18a is set to a size that allows it to rotate (slide) with little resistance without rattling when inserted into the cylindrical portion 6e, and it is detachable (removable) from the cylindrical portion 6e. The diameter of the cylindrical portion 18b is larger than the outer diameter of the pivot shaft 18a and functions as a stopper when inserting the pivot shaft 18a into the cylindrical portion 6e.

[0035] The toothbrushing aid 16 may be attached with the mirror member 18 already attached, or the mirror member 18 may be attached after the toothbrushing aid 16 has been attached. Figure 8 shows the toothbrushing aid 16 in use. Reference numeral 20 indicates the infant's face, 22 indicates the infant's right hand, and 24 indicates the parent's left hand holding the infant from behind. After attaching the toothbrushing aid 16 to the infant's right cheek, the mirror member 18 is attached, and the arm portion 18c is rotated to adjust the reflection in the convex mirror 18d. Once the adjustment is complete, the parent uses a toothbrush held in their right hand to brush the teeth on the side opposite to where the toothbrushing aid 16 is attached, while looking at the convex mirror 18d.

[0036] When an infant is held from behind, the infant can be stably supported and the infant can feel secure, but brushing their teeth becomes difficult because their mouth cannot be seen. Even in such cases, the toothbrushing aid 16 equipped with the mirror member 18 according to this embodiment makes it easy to brush teeth. If the mirror member 18 shown in Figures 7 and 8 is not used, it is also possible to place a separate tabletop mirror with a stand on the table and brush the infant's teeth while reflecting their mouth in the mirror. However, in that case, if the infant moves or turns their face away, the mirror will no longer reflect their mouth. In this respect, the mirror member 18 integrated with the toothbrushing aid 16 shown in Figures 7 and 8 has the advantage that the mirror member 18 always follows the movement of the infant's face, so even if the infant moves or turns their face away, the infant's mouth will continue to be reflected in the convex mirror 18d of the mirror member 18. Therefore, teeth brushing can be performed more easily and reliably. Furthermore, the cylindrical portion 6e also serves as the second tab 4d, which widens the roughly U-shaped opening as shown in Figure 3(a).

[0037] In this embodiment, the arm portion 18c is rotated to adjust the reflection on the convex mirror 18d. However, the configuration may also allow the position of the convex mirror 18d to be adjusted relative to the arm portion 18c. In this case, for example, a protrusion and a groove that fits into it may be formed relatively between the pivot shaft 18a and the cylindrical portion 6e, and the pivot shaft 18a may be fixed so as not to rotate after being inserted into the cylindrical portion 6e. The convex mirror 18d may then be connected to the tip of the arm portion 18c with a universal joint such as a ball joint to adjust the orientation and angle of the convex mirror 18d. In this embodiment, a convex mirror 18d is used as an example of a mirror, but a flat mirror or the like may also be used. The additional configuration of the mirror member 18 can also be implemented in the same way when the configuration of the first toothbrushing aid 4 is used as the basis.

[0038] Although embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various modifications are possible within the scope of the claims, specification, and drawings. For example, although the above embodiments illustrate the use of a pair of toothbrushing aids, a single toothbrushing aid may be used alternately while changing its attachment position.
