- FIG. 2 is a perspective view showing a sensor shock absorbing cover of the present invention mounted on the sensor.
- FIG. 3 is a perspective view of another embodiment of the sensor cushioning cover according to the present invention
- FIG. 4 shows an example of use of the sensor cushioning cover according to the present invention.
- the sensor buffer cover 10 according to the present invention comprises an inner bag-like sheet 20 and an exterior member 30, and is formed so as to encapsulate a sensor 50 used in an intraoral method of digital radiography.
- the sensor buffer cover 10 is a bag-like cover body for inserting the sensor device of the intraoral radiography apparatus, and is formed of a flexible material.
- the inner bag-like sheet 20 is a bag body formed in a substantially rectangular shape.
- the sensor 50 is inserted into the bag-like interior. As shown in FIG. 1, an opening 22 is provided on one side of the tip in the longitudinal direction, and the sensor 50 is inserted from the opening.
- the inner bag-like sheet 20 is a bag body in which two sheets are adhered, and the other three sides other than the opening 22 are joined. In this embodiment, bonding is performed by heat treatment, but when the sensor 50 is inserted, it is necessary to be securely bonded so that the inside is waterproof. In addition, it is possible to make a structure in which a part of the side near the opening 22 is not adhered, and to widen the opening 22 so that the sensor 50 can be easily inserted.
- the inner bag-like sheet 20 is made of a resin material such as polyethylene, polypropylene, vinyl chloride or the like.
- a polyurethane sheet is used in this embodiment.
- the sensor 50 can be easily inserted into the inner bag-like sheet 20 and can be taken out smoothly.
- the width of the inner bag-like sheet 20 is formed to be slightly larger according to the width of the sensor 50. By making the width of the sensor 50 substantially the same, the inner bag-like sheet 20 is not too large compared to the sensor 50, and the sensor 50 does not move within the sensor cushion cover 10 when worn in the oral cavity By doing this, it is possible to prevent high quality photography from becoming impossible.
- the inner bag-like sheet 20 can have a structure in which at least the inner surface thereof is formed in a concavo-convex pattern. By forming the texture, it has slip resistance and can prevent the sensor device from being displaced in the inner bag-like sheet. Even when the sensor cushion cover 10 is formed larger than the sensor 50 by providing the inner bag-like sheet 20 with a non-slip property, the sensor 50 does not move inside without moving the sensor 50 in the middle without stimulating the inside of the mouth Since the affected area can be photographed reliably and appropriately, and the size of the sensor buffer cover 10 is larger than that of the sensor 50, the sensor 50 can be easily inserted and removed. Also, because the size has some allowance, it is possible to allow sensors of slightly different sizes depending on the manufacturer.
- the anti-slip treatment can be performed by embossing a resin material such as polyethylene, vinyl chloride or polypropylene. By embossing, it is possible to suppress the cost and easily provide slip resistance.
- the exterior member 30 is formed by joining two elastic and slightly thick sheet-like bodies in accordance with the shape of the sensor device 50. As shown in FIGS. 1 and 2, the inner bag-like sheet 20 is joined to surround the periphery of the base 24 into which the sensor 50 of the inner bag-like sheet 20 is inserted. The longitudinal edges 32 of the exterior member 30 are also open in this embodiment. The exterior member 30 covers the base of the inner bag-like sheet 20, and the outer peripheral edge 34 of the exterior member is melt-bonded to the base 24 of the inner bag-like sheet and the periphery. By joining the exterior member 30 and the inner bag-like sheet 20, the sensor accommodation portion of the sensor cushion cover 10 is configured in a double bag shape.
- the exterior member 30 is formed in a substantially rectangular shape in accordance with the shape of the sensor device in the present embodiment, the exterior member 30 is not limited to a rectangular shape, and a substantially elliptical shape having rounded corners in accordance with the sensor shape. It is also possible to use an exterior member. Rounding can be effective for patient acceptance, and can also enhance patient comfort. Furthermore, as shown in FIG. 3, it is also possible to have a structure in which both ends on the end side 32 have a slightly expanded width so that the sensor 50 can be easily inserted.
- the exterior member 30 is formed of a material whose outer surface has affinity and flexibility. Since it is a site in contact in the oral cavity, it has an effect of improving the ease of wearing and comfort, and suppressing discomfort during use. For example, it is possible to impart affinity and flexibility by using a somewhat thick material such as resin, silicone, synthetic rubber, sponge, non-woven fabric and the like.
- the outer surface of the exterior member 30 By making the outer surface of the exterior member 30 a non-slippery material such as a sponge or a non-working cloth, slippage can be prevented and the quality of imaging can be enhanced.
- the mouth may be filled with saliva, or unevenness in the mouth may cause the sensor to move or shift easily, making it slippery, difficult to fix in an appropriate position, but with a slip resistant material This can solve this problem.
- it was only a vinyl sheet it was very slippery with saliva or the like in the mouth even if it was used by covering the sensor, and it was difficult to fix it by only pressing lightly.
- a slippery film can be formed on the surface, so it is desirable to use a material with no film at the time of processing when foaming the material in order to obtain slip resistance.
- fine foams with small bubbles are slippery even if the film is removed, it is desirable to use urethane with relatively coarse bubbles or NBR of synthetic rubber.
- the foam-produced material is formed by joining two sheets of a thickness of 0.5 mm to 4 mm, preferably a thickness of 1 mm to 2 mm.
- a urethane material is used for the exterior member 30, and firm fusion bonding is realized by the affinity with the inner bag-like sheet 20 formed of the same polyurethane sheet.
- the exterior member 30 and the inner bag-like sheet 20 can have a structure in which the length in the longitudinal direction is different between the front surface and the back surface. By lengthening one of the sheets obtained by joining the two superposed peripheral edges, it is easy to visually recognize the front and back when the sensor 50 is inserted. Moreover, it is also possible to set it as the structure which longly forms either one side of the exterior member 30 or the inner bag-like sheet

Abstract
Description
口内法デジタルX線撮影では、装置のセンサーと歯牙の歯根尖周囲部位及び咬翼部位の位置決めが重要であるが、患者の苦痛や不快感をできるだけ排除しなければ所望の領域の高品質の画像を捕捉できないという問題があった。
(1)患者の口腔内に入れた時に、患者には不快感、異和感を与えることなく固定でき、無理なく高品質の画像を撮影することができる。内側の袋状シートと、外装部材とが一体になっている為、センサーの挿入がスムーズで使用が容易である。また、長方形状に形成されている為、製造が容易であり、同型のセンサーを挿入し易い構造である。
(3)患者に疼痛と不快感を防止するとともに、センサーを適切な位置に安定して固定することができ、的確な診断効果が期待できる。
(4)衛生的にデジタルX線撮影をすることが可能であり、カバーはディスポーザブルであり、センサー機器を傷付けることなく長期間繰り返し使用することが出来る。
(6)塩化ビニル樹脂またはポリエチレンにより安全性の高くコストを抑えた緩衝カバーとすることが出来る。
(7)センサー緩衝カバーの表面と裏面とで外装部材と内側袋状シートの長さが異なるため、センサー挿入時にセンサーの撮影面と非撮影面とを識別し易い。
本発明のセンサー緩衝カバー10は、内側袋状シート20と、外装部材30と、からなり、デジタルX線撮影の口内法による撮影装置に用いるセンサー50を被包するように形成されている。
内側袋状シート20は、略長方形に形成されている袋体である。袋状の内部にセンサー50を挿入する構造である。
図1に示すように、長手方向の先端の一側辺に開口部22を有しており、開口部からセンサー50を挿入する構造である。内側袋状シート20は2枚のシートを接着した袋体であり、開口部22以外の他の3側辺は接合されている。本実施例では熱処理による溶着により接着されているが、センサー50の挿入時に内部が防水されるように確実に接着されている必要がある。また、開口部22近傍の側辺の一部を接着させない構造とし、開口部22を広くしてセンサー50を挿入しやすくすることも可能である。
また、内側袋状シート20の幅はセンサー50の幅に合わせて若しくはやや大きめに形成される。センサー50の幅を略同じ幅とすることで、内側袋状シート20がセンサー50に比べて大き過ぎないようにして、口腔内に装着したときにセンサー50がセンサー緩衝カバー10内で移動しないようにすることにより、高品質の撮影が出来なくなる事を防止している。
防滑処理は、ポリエチレン、塩化ビニル、ポリプロピレン等の樹脂製の素材をエンボス加工することによって行う事が出来る。エンボス加工により、コストを抑えて簡易に防滑性を持たせる事が出来る。
発泡性素材の場合、表面に滑りやすい皮膜ができるので、防滑性を得るには材料を発泡させる際に加工時の皮膜がない状態のものを使用することが望ましい。また、皮膜を取り除いても発泡した気泡が細かいものは滑りやすいため、比較的気泡の粗いウレタンや合成ゴムのNBR等であることが望ましい。さらに、発泡製造された素材を0.5mmから4mmの厚さのシート、好ましくは1mm~2mmの厚さに薄切りした2枚のシートを接合して形成されることがより望ましい。薄型のシートとすることで厚みによる違和感を感じることなく、快適に撮影を受けることができる。また、ある程度厚みを持たせることで緩衝性を高める効果も期待できる。
また、別の実施例として、ポリウレタンシートの外装部材30に塩化ビニル樹脂の内側袋状シート20を溶着した構造とする事も可能である。更に、内側袋状シート20に防滑処理としてエンボス加工を施したシートを溶融接合する事が好ましい。
センサー50は歯科用の小型の撮影素子ユニットであり、例えば、CMOS、CCDやフィルム状であってもよい。センサー50にはリード線52が延設してあり、センサー50によって得られた画像情報を外部コンピュータに伝送している。
センサー50を保護するために、本件の実施例は、内部のセンサーに対して防水性を備えた構造でもある。例えば、内側袋状シート20を使い捨て用の安価な防水フィルムとすることで、衛生的であるとともに、コストを押さえることが可能となる。本実施例では、内側袋状シート20を防水性のあるポリウレタンシートとすることで防水性のある構成となっている。また、外装部材30にも防水処理を施し、防水を確実にすることも可能である。
さらに、センサー50をカバーする外装部材30のみを親和性および柔軟性のある素材とすることで、コストを削減することが出来る。
