Claims (15)
- 近位端、遠位端、および前記近位端と前記遠位端との間に延在する円筒側壁であって、前記遠位端が、円錐遠位端壁、および前記円錐遠位端壁の遠位端にある流体ノズルを含む、近位端、遠位端、および円筒側壁と、
前記円錐遠位端壁の近位端を越えて前記円筒側壁から軸方向に延在する円筒荷重支持壁であって、シリンジの前記円筒側壁から軸方向に延在し、シリンジの長手方向軸線に対して1度~30度の角度でシリンジの前記円筒側壁から径方向外向きに延在している円筒荷重支持壁と、
前記円錐遠位端壁の周縁に沿って配置された複数の放射状リブであって、複数の放射状リブの長手方向軸線が、前記円錐遠位端壁の少なくとも一部にわたって、前記円筒荷重支持壁から前記流体ノズルに向かって径方向内向きに延在している、複数の放射状リブと、
を備えていることを特徴とする、シリンジ。 - 前記複数の放射状リブが複数の流体保持溝を画定し、前記複数の流体保持溝の流体保持溝が、前記複数の放射状リブの隣接する放射状リブの各対の間に配置され、前記複数の流体保持溝は、毛細管接着によってある容量の流体を保持するように構成されている、請求項1に記載のシリンジ。
- 前記複数の流体保持溝によって保持される流体の容量が、0.1~0.8ミリリットルである、請求項2に記載のシリンジ。
- 前記複数の放射状リブが、前記円錐遠位端壁の荷重強度を高めている、請求項1に記載のシリンジ。
- 前記複数の放射状リブが、前記円筒荷重支持壁の荷重強度を高めている、請求項1に記載のシリンジ。
- 前記円筒荷重支持壁が、流体インジェクタの保持アームの保持面に当接することにより、加圧注入手順中に前記シリンジを圧力ジャケット内に保持するように構成されている、請求項1に記載のシリンジ。
- 前記円筒荷重支持壁の遠位面が、前記シリンジの長手方向軸線に対してより近位の内側部分からより遠位の外側部分まで径方向に傾斜している、請求項1に記載のシリンジ。
- 前記円筒荷重支持壁の遠位面の角度が径方向に傾斜し、それによって前記遠位面は、前記遠位面が流体インジェクタの保持アームの保持面に当接するように、前記保持面と相補的であり、前記シリンジは、前記シリンジの円筒側壁と、前記シリンジが配置される圧力ジャケットとの間に流体が流入するのを防止するように構成されている、請求項7に記載のシリンジ。
- 前記円筒荷重支持壁の遠位面の角度が、流体インジェクタの保持アームに対する径方向内向きの力を大きくするように構成されている、請求項7に記載のシリンジ。
- 前記円筒荷重支持壁および前記複数の放射状リブのうちの少なくとも一方が、流体インジェクタのピストンヘッドまたはプランジャヘッド内の少なくとも1つの電磁放射線源から放出される電磁放射線による、前記円錐遠位端壁の遠位部分における屈折ハロー効果を高めている、請求項1に記載のシリンジ。
- 前記円錐遠位端壁の遠位端にある前記流体ノズルに接続されたネック部であって、前記ネック部が流体通路を含み、前記流体通路が、該ネック部の内面から前記流体通路の内部に少なくとも部分的に径方向内向きに延在する複数の長手方向流体転向リブを有する、ネック部をさらに備えている、請求項1に記載のシリンジ。
- 前記複数の長手方向流体転向リブは、流体が前記シリンジにおける前記円錐遠位端壁の内面および前記円筒側壁の内面に沿って流れるように、前記ネック部の通路を通って流れる流体を前記シリンジ内に転向させるように構成されている、請求項11に記載のシリンジ。
- 前記複数の長手方向流体転向リブのうちの少なくとも一部が、異なる形状を有する、請求項12に記載のシリンジ。
- 前記複数の長手方向流体転向リブのうちの少なくとも一部が、前記ネック部の内面から前記流体通路内へ異なる距離で延在している、請求項12に記載のシリンジ。
- 前記複数の放射状リブは、前記複数の放射状リブの各隣接対間の距離が前記円筒荷重支持壁から前記流体ノズルに向かって漸減するように、前記シリンジの長手方向軸線に対する角度で、前記円錐遠位端壁に沿って延在している、請求項1に記載のシリンジ。
