Abstract

PROBLEM TO BE SOLVED: To push check mucosa by projecting a brush protector for pushing the cheek mucosa at a tip of a brush device body behind a brush rear surface. SOLUTION: About three - fourth of the tip of a cylindrical synthetic resin housing forming an outer cover of an electromotive tooth brush device body 3 is cut out and a brush protector 2 is formed with the rest of the housing in one body. The cross section of the brush protector 2 is semi-circular and has an elastic force, so the brush protector 2 becomes hard to be bent and to be broken. The thickness of the brush protector 2 is about 1 mm to 2 mm. The length of the brush protector 2 is slightly longer than the tip of a brush 5 provided at a brush shaft 4 detachably assembled to a driving shaft projecting to a tip section of the brush device body 3, and the width is about a size for covering the brush 5. Pushing of cheek mucosa can be realized thereby and when the brush 5 is chewed during polishing side surfaces of the teeth, and the movement of the brush 5 cannot be bothered.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric toothbrush for nursing care in which the brush can be moved freely by removing the buccal mucosa with a brush protector when brushing another person's teeth.

[0002]

2. Description of the Related Art When brushing one's own teeth with an electric toothbrush, when applying a brush to the buccal side of a tooth in contact with the buccal mucosa,
Unconsciously moving the jaw creates a space between the teeth and the buccal mucosa. However, when a caregiver brushes the teeth of another person, such as a debilitated sick person or an infant who does not like tooth brushing, with an electric toothbrush, it is very difficult to brush because the buccal mucosa often contacts the buccal surface of the teeth. This is because the user does not want the handle of the operating brush to hit the buccal mucosa, reflexively tensions the cheeks, hinders tooth brushing, and makes it difficult to check the brushing condition.
The strength of the cheek muscles is so great that the brush may even stop moving, such as when using a cheap electric toothbrush with a weak motor horsepower. Therefore, the caregiver must insert the finger of one hand without the electric toothbrush into the mouth of the other person and pull the cheek to form a space between the dentition and the buccal mucosa.

[0003]

However, putting a finger in the mouth and continuing to pull the cheek requires a lot of power, which makes the finger tired unexpectedly. In addition, since saliva wets fingers, it is not very pleasant for those who care for others, even if they are mothers trying to brush their beloved children. In addition, caregivers may be at risk of infection. It's a bad thing even if you're polished, you can't put another person's finger in your mouth. Particularly in the case of infants, pulling the cheeks strongly hurts and screams, and often promotes dislike of brushing teeth. Therefore, an object of the present invention is to add a function of easily removing the buccal mucosa to the electric toothbrush device in order to solve the above problem.

[0004]

In the electric toothbrush for nursing care of the present invention, a brush protector for excluding the buccal mucosa is protruded from a distal end of the electric toothbrush. By applying the brush protector to the buccal mucosa to block the brush and the buccal mucosa, the brush can move freely without being obstructed by the buccal mucosa, and the degree of polishing can be easily checked.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the electric toothbrush for nursing care of the present invention, it is desirable that a brush protector for evacuating the buccal mucosa be integrally formed with the holding housing. Alternatively, provide a mounting means at the rear end of the brush protector,
It may be detachably mounted on various commercially available electric toothbrush devices such as a vibration type, a reciprocating type and a rolling type.

The above-mentioned brush protector is basically a spatula shape, but the shape is not particularly limited, and can be arbitrarily selected as long as the size and the shape can exclude the buccal mucosa.
In addition, it is desirable that the brush protector is made of a hard synthetic resin or a light, non-rusting metal, but the material is not particularly limited.

When the nursing electric toothbrush device 1 provided with the brush protector is used, as shown in FIG. 2, the brush protector 2 acts as a caregiver's finger and is inserted into the mouth of a sick person or infant. The buccal mucosa 9 can be easily and reliably evacuated. For this reason, the movement of the brush 5 attached to the electric toothbrush device main body becomes free. In addition, since the caregiver does not need to put his finger in another person's mouth and keep pulling his cheek, his hands are not tired and his hands are not stained with saliva. In addition, the degree of polishing can be easily checked. Therefore, the caregiver can comfortably and quickly brush the teeth of another person, such as a sick person or an infant.

In addition, the sick or infant on the side of the toothbrush is safe because the operating brush 5 does not irritate the buccal mucosa 9 because it is blocked by the brush protector 2.
It also protects the buccal mucosa. Also, since it is not necessary to put a finger in the mouth and pull the cheek, it is not painful to have the teeth brushed.

[0009]

Embodiments will be described with reference to the drawings.
In FIG. 1, the brush protector 2 provided in the electric toothbrush device 1 for care has a spatula shape with a semicircular cross section. This brush protector 2 is the remaining portion of the cylindrical synthetic resin housing forming the outer shell of the electric toothbrush device main body 3 obtained by cutting off about three-quarters of the front end thereof, and is integrally formed when the housing is manufactured. When the cross section is a semi-circular shape, resilience is imparted, which has the advantage that it is difficult to bend and break. Therefore, the thickness of the brush protector 2 formed by extending the housing is preferably about 1 mm to 2 mm. The length of the brush protector 2 is slightly longer than the tip of the brush 5 provided on the brush handle 4 which is detachably attached to a drive shaft (not shown) projecting from the tip of the electric toothbrush device main body 3. The width may be such that the brush 5 is hidden.

In order to enhance the function of the electric toothbrush for nursing care, it is desirable to provide a light 6 for irradiating light at the tip of the electric toothbrush main body 3, as shown in FIG. By illuminating the dentition with the light 6 while brushing the teeth, the degree of brushing can be confirmed, and at the same time, decayed teeth and alveolar pyorrhea of the sick and infant can be found at an early stage, which is convenient. Alternatively, the brush protector made of transparent acrylic resin may be illuminated with a light provided inside the electric toothbrush device body to illuminate the entire brush protector to illuminate the teeth. Further, although not shown, a liquid suction means for sucking saliva may be provided at the tip of the electric toothbrush device main body.

In the embodiment of the electric toothbrush device 1a for care shown in FIG. 3, a brush protector 2a made of a transparent synthetic resin is detachably attached to the distal end portion of the electric toothbrush device main body 3 using the cylinder 7 as a mounting means. It is installed. That is,
The tip of the slightly tapered tube is split in half and the brush 5
Is exposed, and the cap is fitted to the distal end of the electric toothbrush device main body 3 using the cylinder 7 connected to the rear end of the tubular body as mounting means.

It has been found that by surrounding the brush handle 4 on which the brush 5 is implanted with the dome-shaped brush protector 2a as described above, not only the buccal mucosa can be excluded but also an unexpected effect can be exerted. That is, even if a sick person or an infant tries to stop the movement of the brush by biting their teeth during brushing, when brushing the side surfaces of the teeth, both sides of the dome-shaped brush protector 2A become barriers, 5 does not hinder the movement. Further, even if the teeth are bitten while the cusp surface of the tooth tip is being brushed, the brush 5 can be operated smoothly by using the back surface of the brush protector 2a and prying open the mouth by several millimeters using the principle of leverage. it can.

Surprisingly, it has been found that the electric toothbrush for nursing care can be effectively used for pets such as dogs and cats who do not want to brush their teeth with the electric toothbrush. That is,
Brushing a pet's teeth is more time-consuming and troublesome than an indistinguishable infant, but by using this embodiment equipped with a brush protector, there is less fear of pets due to the vibration and noise emitted by the brush, Also, if you try to bite the brush, it will not bite. For this reason, it is most suitable as an electric toothbrush for old dogs and old cats who have not practiced toothbrushing.

In the embodiment of the electric toothbrush device 1b for care shown in FIG. 4, a loop 8 is provided at the rear end of a metal brush protector 2b such as a stainless steel formed in a spoon shape to provide a mounting means. It is attached to the toothbrush device main body 3. Since the stainless steel plane acts as a mirror,
Early detection of caries and other diseases while brushing the sides of the teeth. Since the handle portion leading to the loop 8 is formed in a thin rod shape, the visual field is not hindered even when the cusp surface of the tooth tip is polished.
Of course, the brush protector 2b of the present embodiment can be manufactured using a hard transparent synthetic resin. In this case, a mirror may be attached to the plane of the exclusion section.

[0015]

The present invention is embodied in the form described above and has the following effects.

[0013] By protruding the brush protector at the tip of the electric toothbrush device body, the buccal mucosa in contact with the side surface of the dentition can be excluded, so that the movement of the brush is not hindered and the degree of polishing can be easily checked. For this reason, it is possible to brush in a short time the teeth of others who are not cooperative for brushing by a caregiver, such as a debilitated sick person or an infant who does not like tooth brushing.

Further, since it is not necessary to put a finger in the mouth and pull the cheek as in the conventional case, the caregiver's hands are not tired and are not stained with saliva. At the same time, sick people and infants on the side to be polished will not feel discomfort because the handle of the operating brush does not hit the buccal mucosa, and will also be free from the pain of pulling on the cheek, and also help protect the buccal mucosa .

Further, as an unexpected effect, it is possible to prevent the tooth from biting the brush during brushing. This makes it possible to brush the teeth of pets such as dogs and cats, which are less recognizable than infants, with an electric toothbrush.
