Description

  The present invention relates to an oral cleaning tool used for cleaning the oral cavity of a care recipient such as a bedridden elderly person, and more specifically, food residue staying in the oral cavity, thickened saliva, phlegm entangled in the pharynx, Or it is related with the intraoral cleaning tool which takes out the denture stabilizer etc. which adhere | attached and remained in the mucous membrane of a hard palate and a mandibular cheek transition part effectively out of the oral cavity.

Due to the recent rapid aging society, the number of care recipients is increasing rapidly. Self-cleaning by aging and mouth breathing by feeding through the nostril through the tube, decreased salivary secretion resulting from decreased masticatory function caused by various diseases, and dry mucous membrane (dry mouse) Becomes extremely bad, and saliva and sputum become more mucous, sticking to the oral mucosa and sticking, making it difficult to drain.
At the same time, tongue coating tends to accumulate, and food residues tend to stay in the hard palate and the cheek cheek transition area.

  In addition, many patients with cerebrovascular disorders remain paralyzed, have inaccessible limbs and have dysphagia, and masticatory muscle group activity such as tongue and cheeks due to poor cleaning of the tooth surface and decreased oral functions due to paralysis And the food tends to stagnate in the oral vestibule, and the oral hygiene is very poor.

In this case, the pharyngeal sputum can be drained with a catheter, but sticky tongue coating and food residues cannot be easily drained.
As a result, aspiration pneumonia and occult pneumonia are often caused by aspiration of resident bacteria in the oral cavity and food residues, leading to death, which is the top cause of death among the elderly .

Therefore, the following tools are used to clean the inside of the oral cavity of care recipients such as bedridden elderly people.
・ General toothbrush ・ Gauze ・ Cotton swab ・ Sponge fixed to the tip of a thin rod ・ Flocked brush planted around the tip of the thin rod (Design Registration No. 1116767: Toothbrush)

By the way, in the case of the general toothbrush,
(1) A general toothbrush is originally intended for scrubbing the tooth surface, which is a hard tissue, and the hair is too hard for dry mucous membranes (dry mice) that tend to bleed.
(2) Since the flocking width of a general toothbrush is narrow and flocked in one direction, the cleaning area is small and the cleaning efficiency is poor.
(3) Since the alveolar ridge is curved in the maxillary nodule and the rearmost buccal cheek transition part, the flocked portion of the straight general toothbrush is difficult to reach, and the tip of the general toothbrush is too large to enter.
(4) It is difficult to hold food residue in the flocked portion of a general toothbrush, and it is difficult to reliably remove it from the oral cavity. Therefore, in the case of lying down, there is a risk of aspiration of the spilled object.

Next, in the case of the gauze, cotton swab, sponge, hairball brush,
(1) Food residues can be partially taken out of the oral cavity by gauze, cotton balls, sponges, and pill-shaped brushes, but they are difficult to hold when they become large food residues because they are difficult to hold them. In the case of a place, there is a risk of aspiration of spilled residue.
(2) The tip cotton swab, sponge, pill-like brush, and thin stick are in a straight line, difficult to follow along the hard palate and the cheek cheek transition part in the mouth with strong curvature, and are difficult to clean.
(3) Furthermore, it is difficult to position and hold the tip of the wrinkle suction catheter on the cotton swab, sponge, or hairball brush.

  In addition, denture stabilizers that hold dentures stably in the oral cavity can remain in the oral cavity when the dentures are removed, especially cream-type denture stabilizers that migrate to the hard palate or mandibular cheek The adhesive remains on the mucous membrane of the part and cannot be easily removed.

  On the other hand, a tongue brush of Japanese Patent No. 3069348 has been proposed by an affiliated company of the present applicant. This tongue brush integrally forms a spoon-shaped cover with a concave portion formed on the lower surface side at the tip of the grip handle, and arranges a large number of hairs spirally on the wire to scrape the tongue coating on the back of the tongue Forming a brush body, bending the brush body outwardly on the lower side of the cover so that the wire of the brush body is covered by the cover, and wire rods at both ends of the brush body; The tongue coating attached to both sides of the lower surface of the cover and scraped by the brush body is prevented from leaking from the upper side of the brush body and is sunk in the cover, and the brush body is pressed against the tongue back Excessive deformation is suppressed by the cover.

However, this tongue brush scrapes the tongue moss on the back of the tongue, and a spoon-shaped cover is integrally formed at the tip of the grip handle. Cannot be used for dry mucous membranes, which tend to bleed, because they do not enter the narrow part where the alveolar ridge is curved, such as the cheek transition area, and because the numerous hairs arranged in a spiral on the wire are hard and short Can not.
