Description
本出願は、2012年12月23日出願の米国仮特許出願第61/745,640号の優先権を主張し、その出願の開示全体は、ここで参照することによって本願の一部をなしている。
本明細書に記載される実施例は、ねじれ耐性チューブを対象としたものである。例示のねじれ耐性チューブの一応用形態は、胃腸への応用形態である。
1)G−Jボタンの耐久性が延びる。
2)十分な栄養を受けることがすでに困難な患者に、より信頼度の高い栄養補給を提供する。
3)画像下治療によるG−Jの交換数を減らす。
4)病院に通う頻度が減る。
5)患者の放射線被曝量が減る。
6)12フレンチボタン等の今日使用されるボタンよりもより小さいG−Jボタンが開発される確率が高くなる。
7)両親、患者、及び医師に安心を与える。
8)チューブ10の遠位端が逆行することを防ぎ、チューブがらせん回転しながら胃の中に戻ることを防止する確率が高くなる。
9)蛍光透視法による配置中に良く見える、316Lステンレス等のステンレス鋼製の医療グレードばねを使用する能力が上がる。
10)装置が胃の中でらせん状に巻き始めた場合にも、装置を通る流れを維持する能力を改善する。
Claims (6)
- 多腔型供給チューブ装置であって、
少なくとも2つの管腔をその近位端に有し、少なくとも1つの管腔をその遠位端に有する多腔型チューブであって、前記管腔が少なくとも胃管腔と空腸管腔とを備える、前記多腔型チューブと、
G−Jボタンと、
前記空腸管腔の中に挿入される空腸チューブであって、当該空腸チューブの最も近位端は円錐形部分からなり、当該円錐形部分が前記空腸チューブから放射状に拡がり、
当該空腸チューブは、前記G−Jボタンの開口部の中を前記空腸管腔の中まで挿入され、それによって
前記円錐形部分が前記G−Jボタンの内部表面と結合し、前記空腸チューブを、前記空腸管腔と、前記G−Jボタンに連結し、
前記多腔型供給チューブ装置にねじれ耐性の特徴を付与するために、前記最も近位端の前記円錐形部分の直下から前記空腸チューブの長さに沿って途切れなく配置されたばねと、
を備える多腔型供給チューブ装置。 - 前記胃管腔及び前記空腸管腔は三腔部分の長さの範囲内でおおむね同じ長さであり、前記空腸チューブの長さは前記胃管腔及び前記空腸管腔の長さよりも大きい、請求項1に記載の多腔型供給チューブ装置。
- 前記円錐形部分は前記空腸チューブに一体的に成形される、又は前記円錐形部分は前記空腸チューブの最近位端にオーバーモールドされる、請求項2に記載の多腔型供給チューブ装置。
- 前記ばねは、前記空腸管腔の壁に埋め込まれる、請求項1に記載の多腔型供給チューブ装置。
- 前記円錐形部分が、前記空腸チューブの他の部分よりもデュロメータ硬度が高い材料でできている、請求項1に記載の多腔型供給チューブ装置。
- 前記ばねが前記空腸チューブの中へ挿入され、前記空腸チューブの内壁と接触している、請求項1に記載の多腔型供給チューブ装置。
