JP4738854B2 - Ultrasonic mouth washer - Google Patents

Description

The present invention relates to an ultrasonic mouth washer that can clean the inside of the mouth simply by placing it in the mouth.
Ultrasound that can easily clean the mouth even if the so-called handicapped person, bedridden elderly person, patient in bed, etc. (also called care recipients) cannot be cleaned normally with a toothbrush It relates to a mouth washer.

Conventionally, toothbrushing using a so-called toothbrush was normally performed, but recently, several toothbrushes using a vibration principle have been developed.
Such a vibrating toothbrush presses the brush against the tooth surface and removes plaque and the like by the vibration, and has no effect on the portion where the brush does not reach.
For this reason, toothbrushes that use the principle of generating cavitation via saliva and removing plaque and the like by the energy have been developed (see, for example, Patent Document 1).
Such a toothbrush is called an ultrasonic toothbrush and is useful in that it can remove plaque and the like even in a portion where the brush does not directly contact.

However, most ultrasonic toothbrushes are formed in a rod shape, and a grip and a thin toothbrush portion are linearly integrated.
Then, the person grips the grip part and puts the brush part into the mouth to brush the teeth.
It is very easy for a healthy person to grip such a grip portion, but it is difficult for a person with a handicap to grip.
For such a handicapped person, that is, a cared person, the caregiver needs to insert an ultrasonic toothbrush into the cared person's mouth to assist in brushing the teeth.
For this reason, toothbrushing work has to be carried out by two persons, the cared person and the caregiver, which is a burden and is inconvenient.
Naturally, it is not comfortable for caregivers who are handicapped.

The ultrasonic mouth washer 1 has a gripping portion 3 formed so that a human (usually a care recipient who is handicapped) 2 can easily grip between the upper and lower teeth. .
Specifically, the held portion 3 is formed in a triangular shape having a wide front and a narrow back, and the held portion 3 is provided with an oscillation element 9 capable of ultrasonic vibration.
The oscillation element 9 includes an oscillation plate 9 a, and the oscillation plate 9 a is provided so as to be attached to the front side of the oscillation element 9.
In addition, a cutout portion 11 for exposing the oscillation plate 9a to the outside is formed in the held portion 3.
The gripped portion 3 formed in a triangular shape includes a horseshoe-shaped tooth contact portion 3A sandwiched between upper teeth and lower teeth and a plate-like tongue contact connecting the tooth contact portions 3A. Part 3B.
The tongue abutting portion 3B is curved upward, and the tongue can be accommodated in the lower space S formed by this curvature with a margin when used.

In the tooth contact portion 3A, oscillation elements 9 capable of ultrasonic vibration are provided on the upper surface and the lower surface, that is, the upper tooth side and the lower tooth side.
In this case, it is more preferable that the oscillating element 9 is provided at a position where it is bitten by the upper and lower back teeth from the viewpoint of intensive cleaning of the back teeth that are likely to become decayed teeth.

In the tongue contact portion 3B, an oscillation element 9 capable of ultrasonic vibration is provided on the lower surface, that is, the tongue side (that is, the lower palate side).
Therefore, in a state of use in which the gripped portion 3 is inserted into the mouth, the tooth contact portion 3A is contacted along the human teeth and the tongue contact portion 3B is contacted along the tongue.
In this case, the tooth contact portion 3A is sandwiched between upper and lower teeth, and the tongue is housed in the space S formed below the tongue contact portion 3B.
Therefore, when the cared person bites the gripped portion 3, the gripped portion 3 is held in a stable state and does not come off.
Further, since the oscillation element 9 is positioned so as to correspond to the upper and lower teeth and tongue, an accurate cleaning effect can be obtained during use.

Now, at the rear of the gripped portion 3, a low vibration imparting portion 4 is formed so as to be once narrowed and slightly enlarged, and is extended so as to impart low vibration to the entire gripped portion. be able to.
A vibration motor 13 is provided in the low vibration applying unit.
Incidentally, an eccentric weight is attached to the rotation shaft of the vibrator motor 13, and the rotation of the weight generates a vibration corresponding to the weight.
Therefore, when the ultrasonic mouth washer is used, the cared person can feel the vibration, and an accurate feeling of use (that is, the cared person can recognize that the mouth is being washed) can be obtained.

Now, the oscillating element 9 of the held portion 3 and the vibrator motor 13 of the low vibration applying portion 4 are connected to a controller 6 having a control portion for controlling them.
More specifically, a cable 5 is connected to the rear part of the low vibration applying unit 4, and is coupled to the controller via the cable 5.
The controller 6 has a so-called mouse shape so as to be easy to use. For example, the controller 6 can be connected to a household power supply.

  Of course, a replaceable power source (for example, a nickel metal hydride battery or a nickel cadmium battery) can be provided inside the controller 6, or a rechargeable battery power source (for example, a lithium ion rechargeable battery) can be provided. Of course it is possible.

In addition, the low vibration imparting portion 4 is formed with a constricted portion 15 at the boundary with the gripped portion 3, and the lips fit in this portion during use, so that stable wearability can be obtained.
In addition, the lip fits in the constricted portion 15 as described above, so that the gripped portion 3 can be isolated from the outside, and saliva or the like generated during use does not leak outside.
The low-vibration imparting portion 4 is provided with a ring-shaped housing 12 at a position near the gripped portion 3.
If the housing 12 is present, it is possible to prevent the low vibration applying portion 4 from being carelessly gripped when gripping the gripped portion 3, and tooth breakage and the like can be prevented.

Further, when the lips are brought into contact with the housing 12, if the position of the oscillating element 9 is set so as to correspond to the back teeth, the held portion 3 can be set at an accurate position.
Furthermore, there is also an advantage that saliva or the like can be prevented from being transmitted to the low vibration applying part side during washing.
The housing 12 can be integrated with the low-vibration applying portion 4, but can be removed by press-fitting attachment.

The controller 6 is connected to an electrode member 7 (described later) that functions in the ion effect.
As the electrode member 7, a necklace-like conductive chain (for example, a metal chain or the like) is used, and it is preferable that the electrode member 7 is in contact with the cared person's neck during use (see FIG. 1).
Here, the oscillating element side of the gripped portion is set to a negative pole and the electrode member side is set to a positive pole, and the gripped portion 3 and the electrode member 7 are opposite to each other.

Therefore, in the state where the held portion 3 (that is, the oscillating element 9) which is a minor pole is inserted in the mouth, the electrode member 7 which is a plus electrode is brought into direct contact with the skin of the neck, thereby the held portion 3 And a human body can generate a voltage via a control unit.
Due to the generation of voltage, negative ions are generated in the saliva accumulated in the mouth of the human 2 to obtain a so-called ion effect.
Incidentally, when negative ions are generated, the negative ions are combined with calcium ions to change to non-ionized calcium, thereby reducing calcium ions causing plaque.

By the way, it is preferable that the outer surfaces of the above-described gripped portion 3 and the low vibration applying portion 4 are covered with an elastic member 10 such as silicon rubber.
For this reason, when the gripped portion 3 is chewed by upper and lower teeth, the tooth contact is good and the burden on the gingiva is small.
In addition, the teeth bite into the silicon rubber to reliably receive the teeth and prevent the gripped portion 3 from being displaced or pulled out during cleaning.
In addition, by forming a large number of small protrusions (not shown) on the elastic member, the cared person with a weak biting force can be more securely fixed to the teeth, and can exhibit a detachment preventing effect.

Next, the above-described controller 6 incorporating the control unit will be described.
On the upper surface side of the controller 6 in the shape of a mouse, an ON button 6a for ultrasonically vibrating the oscillation element 9 of the held portion 3 or driving the vibrator motor 13, and an OFF button for stopping the vibration and driving. Button 6b is provided.
Further, when the controller 6 presses the ON button 6a, it automatically operates without pressing the OFF button 6b, for example, as a timer so that the supply of current to the oscillation element 9 and the vibrator motor 13 is completed after 3 minutes. It is also designed.
Of course, when the timer functions in this way, the OFF button 6b can be omitted.

Next, the control circuit of the control unit of the ultrasonic mouth washer 1 will be described with reference to FIG.
The controller 6 includes a circuit control unit 16 that controls the whole, an ultrasonic transmitter 17 that generates an ultrasonic signal, a timer unit 18 that controls an ultrasonic transmission time, and an ion current that controls an ion generation current. And a control unit 19.
The circuit control unit 16, the ultrasonic transmitter 17, the timer unit 18, and the ion current control unit 19 are mounted on an electric circuit board.

The circuit control unit 16 controls generation of ultrasonic vibration and ion current, and current is supplied by pressing an ON button 6 a provided on the upper surface side of the controller 6.
Control of ultrasonic vibration is performed by inputting an ultrasonic voltage signal from the ultrasonic transmitter 17 to the oscillation element 9 which is a piezoelectric element.

On the other hand, the ion current is controlled by the ion current control unit 19 adjusting the voltage between the oscillation plate 9 a and the electrode member 7.
In addition, as the electrode member 7, as described above, a necklace-like conductive chain that is hung on the neck or the like and is in contact with the skin is used.
The circuit control unit 16 also plays a role of controlling the vibrator motor 13.
The design of these control units can be implemented by known means.

According to the present invention, when a human bites a horseshoe-shaped tooth contact portion 3A between upper teeth and lower teeth, the tongue can be stored in the space below the tongue contact portion 3B.・ Stable and difficult to remove during use.
Therefore, even if the care recipient is handicapped, once the caregiver inserts and sets it in the mouth, the caregiver's help is completely unnecessary, which is extremely convenient.
Cavitation is generated through saliva, and the dental plaque can be washed by the energy, and also the tongue coating of the tongue can be washed, so that highly efficient mouth washing is possible.
In addition, there is an advantage that the cleaning power by the ion effect can also be obtained.
During use, since low vibration is applied, vibration can be sensed and a sufficient feeling of use can be obtained.
Further, the body 12 prevents saliva from being transmitted from the bared portion 3.

Although the present invention has been described above, the present invention is not limited by the embodiments, and various modifications are possible as long as the object is met.
For example, the size of the oscillation element 9 provided in the held portion 3 is not limited to that shown in the embodiment, and the number of the elements can naturally be larger than that in the embodiment.
The shape of the low-vibration imparting portion can be changed as appropriate as long as the vibrator motor 13 can be disposed.
In addition, although an example has been described in which the oscillation plate 9a provided in the held portion 3 is a negative electrode and the electrode member 7 is a positive electrode, this polarity may be reversed.

  The present invention mainly cleans the mouth even when a person who is handicapped or a caregiver such as a bedridden elderly person or a patient in a hospital bed cannot perform mouth washing such as brushing with a toothbrush. The present invention relates to an ultrasonic mouth washer that can be used. However, as long as the principle of mouth washing of the present invention can be used, the present invention is sufficiently applicable to mouth washing of other fields, such as pets.
