Abstract
Description
一方の側だけにばね作用を及ぼして安全位置に戻すトリガー機構。これらのトリガー機構は、使用時に端キャップをニードル軸線に向かって傾け、ニードル先端を破損し、使用できなくする場合がある。
先ず最初に、図1のa乃至gは、本願と関連した上記出願PCT/GB00/04416に記載された従来技術に関するものであり、当該出願のPCT/GB00/04416に記載された図5a乃至gに対応する。従って、以下の説明は図2乃至図5について説明する。
ニードル受け入れ部分11は、ニードル(図4のa、b、c参照)及び/又はニードルルエル(luel)組み合わせ、及びこのようなアッセンブリを受け入れる。シース部分12は、貫通ボア15を持つノーズプレート14、及びニードル受け入れ部分11とノーズプレート14との間を延びる弾性的に撓むことができる脚部16、17を含む。これらの脚部は、ニードル受け入れ部分11及びノーズプレート14との接続部にヒンジ18、19によって作動的に連結されている。
安全装置10の弾性的に撓むことができる脚部16、17の各々は、脚部後部分16a、17aを脚部前部分16b、17bから分離する中央膝関節20、21を有する。脚部分16a、17a及び膝関節20、21の形体により、ノーズプレート14に作用する長さ方向力が自然の押圧力を強化する。脚部後部分16a、17aに配置された弾性バンド22の形態の弾性手段は、脚部16、17が変形したり外方に撓んだりしないようにし、アッセンブリが準備ができていない場合に針刺し事故が起こり難くし、アッセンブリがもはや準備位置にない場合にアーム16、17及びノーズプレート14が延長位置に確実に戻るようにする。バンド22は、両脚部16a、17aの外面に、これらの脚部16a、17aに配置された固定ラグ23a、23bを固定することによって所定位置に保持される。これらの固定ラグ23a、23bの中間にかつ脚部16a、17aの上面周囲に、剛性タブ24a、24bを含む解放手段24が配置されている。これらのタブ24a、24bは、トリガー機構13の導入部として作用する三角形切り欠き領域を形成する。
脚部16、17を分離するときの部分25の下方への係合移動は、係合部分25を準備位置にラッチ止めするとき、更に大きな圧力を下方に加えることにより脚部20、21の中心とニードルの中心とを一直線上に並んだ状態に保持しようとする。

Claims (5)
- 特に経皮ニードルで使用できる、トリガー機構を組み込んだ安全装置であって、前記トリガー機構はその作動時に前記装置を作動準備し、一つ又はそれ以上のニードル取り囲み脚部をニードル軸線から遠ざかるように撓ませることによって、使用されているニードルのシース解除を開始し、初期作動準備及び脚部撓ませ移動をトリガーの作動部分と前記脚部又は各脚部との、又はこれに作動的に連結された部材との相互作用によって行う安全装置において、このような移動が起こったとき、前記トリガー端部は、前記脚部又はこれに連結された前記部分と、これらの二つを係合状態に積極的に保持し且つラッチ止めするように相互作用することを特徴とする、装置。
- 請求項1に記載の装置において、注射を行うために使用者が前記ニードルを徐々に延ばすときに協働ラッチ止め係合状態が自動的に解放され、前記トリガーは、次いで、注射を完了した後にニードルを引っ込めるとき、続いて行われるニードル取り囲み閉鎖位置への前記脚部又は各脚部の戻しを妨げないように自動的に移動し、前記アームから離れる、装置。
- 請求項1又は2に記載の装置において、前記トリガーは、使用者が、この部分を、ほぼニードル軸線の方向で前方に押すのでなく、脚部−ニードルアッセンブリ内に直観的に押し下げるように、二つの湾曲を備えた輪郭を有する、装置。
- 請求項3に記載の装置において、前記トリガーの材料は、前記トリガーを押圧して係合させるとき、一方の湾曲領域が他方よりも大きく変形するような性質を備えている、装置。
- 添付図面の任意の適当な組み合わせを参照して説明された、又はこれらに例示された装置。
