Description
好ましくは、可とう性プラスチックカバーを設けるために、オーバモールド処理が用いられる。
ばね31は、継続してランセット19に力を加え、ヘッド29を通して針の先端を駆動する。これによって、針の周囲でスリーブ30が蛇腹状に折り畳まれることになる。針先端21は、接触板13の開口14を通して駆動され、使用者の皮膚を突き刺す。この時点で、ばね31は、多少過度に伸長しているので収縮し始め、ランセットを引張り、ランセットとともに、針先端を接触板の開口を通してケース内に戻す。
Claims (4)
- 使用者の皮膚に刺すためのランセットであって、
概ね硬質のプラスチック材料からなる本体と、
一方の端部は前記本体に埋め込まれ、先鋭な針先端を含む他方の端部は前記本体から突出するようにされている針と、
前記針の露出した長さ全体を覆う可とう性プラスチックカバーとを含み、前記カバーは、前記本体に対して相対的に、前記カバーに加えられる軸力によって、前記カバーの少なくとも軸部が前記針に沿って蛇腹状に折り畳まれて、前記針先端を露出させるような材料および寸法で形成されており、
前記カバーは、前記軸力がなくなった後で前記針先端を覆うために復帰することのないような材料および寸法で形成されていることを特徴とする、ランセット。 - 前記可とう性プラスチックカバーは、前記針先端を囲むヘッド部と、前記ヘッド部より狭く、前記針の残り部分を囲むスリーブ部とを含み、それによって、使用の際、前記カバーのヘッドに前記軸力が加えられ、それに応じて前記スリーブ部が針に沿って蛇腹状に折り畳まれる、請求項1に記載のランセット。
- 前記可とう性プラスチックカバーは熱可塑性エラストマー材料である、請求項1または2に記載のランセット。
- 針の頂部に可とう性プラスチック材料をオーバモールドすることで前記可とう性プラスチックカバーを形成することを含む、請求項1から3のいずれか1つに記載のランセットを製造する方法。
