Description

  When the caregiver cleans the oral cavity of a patient with dementia that cannot be opened as instructed or a patient requiring care, such as paralysis and reduced opening force, with a toothbrush, etc. In addition, the present invention relates to an opening guide holder that guides to an opening state of a size necessary for an individual patient and holds the guided opening state safely.

  When using a hard stick such as a toothbrush handle to clean the oral cavity of a patient with dementia or a care recipient who has reduced opening force, if the hard stick is forcibly inserted between the upper and lower dentition, The weakened tooth may be damaged or the loose tooth may fall off due to alveolar pus leakage, and the gums and mucous membranes may be stabbed with a hard stick to bleed. Forcibly opening the mouth may damage the temporomandibular joint.

In view of this, an opening device has been proposed in which the tip of the rectangular main body having a slight elasticity is formed into a mountain shape (see, for example, Patent Document 1).
Japanese Patent Laying-Open No. 2004-81774 (first page, FIG. 1)

  In the case of the proposed conventional opener, the thickness of the body part is constant when inserted from the tip of the chevron to the rectangular body part between the upper and lower dentitions. There is a problem that an opening state of a large size cannot be obtained.

  In consideration of the above points, the present invention is capable of forcibly and safely inducing an opening state having a required size that varies depending on an individual patient from the closed state in a stepwise manner and maintaining the induced opening state. An object is to provide a holding tool.

  It is another object of the present invention to enable smooth transition from a small opening state to a large opening state with little resistance in a stepwise manner.

  It is another object of the present invention to perform oral cleaning while observing whether there is a bleeding state in the oral cavity in the open state.

  And it aims at making it cheap and making opening guidance work and handling easy.

The opening guide holder of the present invention is
A thin outer wall with a small thickness that can be restored flat, a short cylindrical insertion part,
From the insertion part, a large outer diameter with a large thickness, a long cylindrical base part, and
The front end is connected to the rear end of the insertion portion, the rear end is connected to the front end of the base portion, and the outer surface is formed with a plurality of concave portions whose outer diameter is gradually increased from the front end side to the rear end side. And a frustoconical hollow adjusting portion (claim 1).

  In addition, it is desirable that the adjustment portion is formed such that gentle convex portions and gentle valley-like concave portions are alternately formed in a wave shape.

  Further, it is preferable that the thickness of each concave portion of the adjusting portion is increased stepwise from the front end side to the rear end side.

  And it is preferable that the surface was comprised from the smooth synthetic resin (Claim 4).

  In addition, the total length is 10 to 20 cm, and the insertion portion is preferably 10 to 15%, the adjustment portion is 15 to 25%, and the base portion is 60 to 75% with respect to the total length. Item 5).

  In the opening guide holder of the present invention, since the insertion portion has a thin, thin and thin outer diameter and a short cylindrical shape that can be restored, the insertion portion is crushed flat with a fingertip and flattened. By doing so, it is easy to insert the insertion portion between the upper and lower tooth rows not only when the upper and lower tooth rows are slightly opened, but also when the upper and lower tooth rows are closed.

  After inserting the flat insertion portion between the upper and lower tooth rows, the insertion portion gradually recovers to a cylindrical shape due to the repulsive force of the insertion portion, and the upper and lower tooth rows are located above and below the cylindrical outer surface of the insertion portion. To the length of the outer diameter, that is, the length of the outer diameter, and the opened state is maintained.

  Next, since the base has a large outer diameter and a long cylindrical shape that is thicker than the insertion part, it is easy to stably hold the base, and the adjustment part has its tip at the rear end of the insertion part. In addition, the rear end is connected to the tip of the base, and the outer surface has a hollow shape of a short truncated cone having a plurality of concave portions whose outer diameter is gradually increased from the tip side to the rear end side. Therefore, according to the required opening degree of each patient, the adjustment part is pushed in between the upper and lower dentitions sequentially from the small outer diameter depression of the adjustment part to the larger outer diameter depression, and between the upper and lower dentitions. By positioning the concave portion having the outer diameter of 2 mm, it is possible to maintain a required opening state for each patient.

  In this state, even if the patient tries to push out the insertion part of the holder with the tongue, the upper and lower teeth are positioned in the recess, so that the patient cannot push out and the holder does not come off the oral cavity (Claim 1). .

  Next, the adjustment portion is formed by gradually forming a convex portion having a gentle mountain shape and a concave portion having a gentle valley shape in a wavy shape, so that the adjustment portion has a large outer diameter from the concave portion having a small outer diameter between the upper and lower teeth. The transition to the concave portion of the diameter can be smoothly performed with little resistance (Claim 2).

  Furthermore, by increasing the thickness of each concave portion of the adjustment unit stepwise from the front end side to the rear end side, the greater the outer diameter, the greater the thickness and strength, and the force to close the patient. (Claim 3).

  In addition, since the opening guide holder is made of a transparent synthetic resin having a smooth surface, the insertion between the holder insertion portion and the adjustment portion between the upper and lower tooth rows is smooth and easy to insert, and the inserted opening The oral cavity can be cleaned while observing the presence or absence of a bleeding state in the oral cavity in the state (Claim 4).

  In addition, the total length is 10 to 20 centimeters, the length of the insertion portion is 10 to 15%, the length of the adjustment portion is 15 to 25%, and the length of the base portion is 60 to 75%. In addition, the balance of the base portion is good, the insertion operation between the upper and lower tooth rows, the adjustment operation of the opening degree, and the gripping state of the base portion are kept well, and the cost can be reduced.

The best mode for carrying out the present invention will be described with reference to FIG. 1 and FIG. 2 which is a partially enlarged view of FIG.
In these figures, 1 is a thin cylindrical insertion portion with a small wall thickness and a small outer diameter, which has elasticity, and can be flattened and flattened by a fingertip, flattening, and excluding the pressing force of the fingertip Then, it is restored to its original cylindrical shape by a repulsive force due to elasticity, and can be restored flat.

  Reference numeral 2 denotes a cylindrical base portion that is thicker than the insertion portion 1 and has a large outer diameter and a length, and has a sufficient strength as a gripping portion. The outer periphery of the rear end of the base portion 2 has no corners and is a curved surface. ing.

  Reference numeral 3 denotes a hollow trimming portion having a short truncated cone, the front end of which is continuous with the rear end of the insertion portion 1, and the outer surface and inner surface of the front end are connected to the outer surface and inner surface of the rear end of the insertion portion 1. Are connected to the front end of the base 2, and the outer surface and the inner surface of the rear end are connected to the outer surface and the inner surface of the front end of the base 2.

  Reference numeral 4 denotes a plurality of gentle valley-shaped concave portions formed on the outer surface of the adjusting portion 2 at substantially equal intervals in the front-rear direction. The diameter of the bottom portion of the concave portion 4, that is, the outer diameter is changed from the front end side to the rear end side. It is getting bigger gradually.

  5 is a gentle mountain-shaped convex part, between the adjacent recessed part 4, between the recessed part 4 of the front end side, and the rear end of the insertion part 1, and between the recessed part 4 of the rear end side, and the front-end | tip of the base part 2 The convex portions 5 and the concave portions 4 are alternately positioned, and the outer surface of the cross section has a gentle wave shape.

  Moreover, as for the mountain-shaped inclination of the convex part 5, the front side is gentle and the rear side is a little steep.

  And the insertion part 1, the adjustment part 3, and the base 2 are pipe-shaped as a whole, and are comprised from the transparent synthetic resin with smooth surfaces, such as a silicone resin.

  Next, when the caregiver cleans the oral cavity of a patient with dementia that cannot be opened as instructed, or a patient requiring care, such as a paralyzed patient who has reduced opening force, the insertion part 1 is crushed flat with a fingertip. By inserting and flattening, it is easy to insert the insertion portion 1 between the upper and lower tooth rows.

  In the case of a patient whose upper teeth are positioned forward of the lower teeth in the closed state, the upper teeth are lifted by inserting the flat insertion portion 1 against the lower surface of the upper teeth. Part 1 is inserted between the upper and lower teeth.

  And after inserting the flat insertion part 1 between the upper and lower tooth rows, the insertion part 1 is gradually restored to a cylindrical shape by the repulsive force due to the elasticity of the insertion part 1, and the cylindrical shape of the insertion part 1 is between the upper and lower tooth rows. It opens to the vertical length of the outer surface, that is, the length of the outer diameter, and the open state is maintained.

  Next, according to the required opening degree of each patient, the adjustment part 1 is pushed in between the upper and lower tooth rows, and the concave portion 4 having the required outer diameter is positioned between the upper and lower tooth rows. Thereby, a required opening state can be hold | maintained to each patient.

  In this state, even if the patient tries to push out the insertion part 1 of the holding tool with the tongue, the upper and lower teeth are positioned in the concave part 4 and cannot be pushed out by the convex part 5, and the holding tool does not come off the oral cavity.

  And since the adjustment part 3 has the gentle mountain-shaped convex part 5 and the gentle valley-shaped recessed part 4 alternately formed in the wave shape, the small outer diameter of the adjustment part 3 between upper and lower tooth rows The transition from the recessed portion 4 to the recessed portion 4 having a large outer diameter can be smoothly performed with little resistance.

  Further, since the surface of the opening guide holder is made of a smooth transparent synthetic resin, the insertion of the holder between the insertion part 1 and the adjustment part 3 between the upper and lower teeth is smooth and easy to insert. The mouth can be cleaned while observing whether there is a bleeding state in the mouth in the opened state.

A first embodiment of the present invention will be described with reference to FIG. 1 and a partially enlarged view of FIG.
The outer diameter of the insertion portion 1 is 18φ, the thickness is 1.8 mm, the length is 20 mm, the outer diameter of the first recess 4 of the adjustment portion 3 is 21φ, the thickness of the first recess 4 is 2.5 mm, The outer diameter of the second concave portion 4 is 24φ, the thickness of the second concave portion 4 is 3.2 mm, the outer diameter of the third concave portion 4 is 27φ, the thickness of the third concave portion 4 is 3.9 mm, and the adjusting portion 3 The lengths of the tip and the first recess 4, the lengths of the first recess 4 and the second recess 4, and the lengths of the second recess 4 and the third recess 4 are respectively 10 mm, 3, the length of the concave portion 4 and the rear end of the adjusting portion 3 is 5 mm, and the total length of the adjusting portion 3 is 35 mm.

  The outer diameter of the base 2 is 30φ, the wall thickness is 4.5 mm, the length is 105 mm, and the total length of the opening guide holder is 160 mm.

  The inner surface of the adjusting portion 3 is continuous with the inner surface of the rear end of the insertion portion 1, the rear end is connected with the inner surface of the front end of the base portion 2, and the inner diameter gradually increases from the front end side to the rear end side. .

  Here, since the length of the insertion part 1 is flattened by the fingertip and inserted between the upper and lower tooth rows, at least 10 mm is required, and if it exceeds 30 mm, it is too long and obstructs the oral cavity.

  Moreover, since the length of the adjustment part 3 forms the some recessed part 4, at least 15 mm is required, and when it exceeds 50 mm, it will become obstructive in an oral cavity.

  Next, the length of the base 2 is required to be at least 60 mm from the viewpoint of gripping, and if it exceeds 150 mm, it is too long and obstructs the handling.

  That is, as an opening guide holder, the total length is 10 to 20 cm, and the insertion portion 1 is 10 to 15%, the adjustment portion 3 is 15 to 25%, and the base portion 2 is 60 to 75% of the total length. Thereby, the balance of the insertion part 1, the adjustment part 3, and the base part 2 is good, the insertion operation between the upper and lower tooth rows, the adjustment operation of the opening degree, and the gripping state of the base part are well maintained, and the cost can be reduced.

  In the embodiment, the case where the number of the recesses 4 is three has been described, but it is needless to say that the number of the recesses 4 may be two or more.

It is sectional drawing of one form of implementation of the opening guide holder of this invention. It is a one part enlarged view of FIG.
