Abstract | PROBLEM TO BE SOLVED: To realize a simple, inexpensive, reliable and disposable medical puncturing device for use in collecting blood samples.SOLUTION: A lancet device includes a housing and a lancet having a puncturing element. The lancet is disposed within the housing and is adapted for axial movement between an initial or pre-actuated position in which the puncturing element is disposed within the housing, and a puncturing position in which the puncturing element extends through a forward opening in the housing. The lancet device includes a drive spring disposed within the housing for biasing the lancet toward the puncturing position, and a retraction or return spring for returning the lancet to a position within the housing in which the puncturing element is disposed within the housing. The retraction spring thereafter maintains engagement with the lancet to assist in preventing the puncturing element from again projecting outward from the forward opening in the housing.SELECTED DRAWING: Figure 44
【課題】医療用穿刺装置において、血液サンプルを収集するのに使用する、簡単で、安価で、信頼性があり使い捨てを可能とする。【解決手段】ランセット装置は、ハウジングと、穿刺要素を有するランセットとを備えている。ランセットはハウジング内に配置されており、穿刺要素がハウジング内に配置されている初期または予備作動位置と、穿刺要素がハウジング内で前部開口を通って延びている穿刺位置の間の軸方向移動に適応されている。ランセット装置は、穿刺位置に向かってランセットを付勢させるようにハウジング内に配置された駆動ばねと、穿刺要素がハウジング内に配置される、ハウジング内の位置までランセットを戻す引き込みまたは戻りばねとを備えている。引き込みばねはその後、穿刺要素がハウジング内の前部開口から外側に再び突出しないようにするのを助けるように、ランセットとの係合を維持している。【選択図】図44 |
