Lancets with improved coupling features and sterility caps
View Patent ↗Improved lancet configurations and protective lancet endcap configurations are disclosed. In example forms, one or more flexing cantilevers project from the lancet body for coupling with a cooperating receiver of a lancing device. A gripping handle extends from a sterility cap for ease of removal from and replacement over the lancet tip. A lancet body has a smoothly curved wave contour with at least one crest and at least one trough for engagement with a cooperating receiver of a lancing device.
1. A protective sterility cap for a lancet, said sterility cap comprising a primary sheath for initial embedment of a sharp lancing tip of an unused lancet therein, a secondary sheath for receiving the sharp lancing tip of a used lancet, and a gripping handle portion extending between the primary sheath and the secondary sheath, with the primary sheath attached at a first end of the gripping handle portion and the secondary sheath attached at a second end of the gripping handle portion when the protective sterility cap is removed from the lancet.
2. The protective sterility cap of claim 1 , in combination with a lancet.
3. The protective sterility cap of claim 1 , further comprising at least one flat display surface for placement of branding indicia thereon.
4. The protective sterility cap of claim 1 , wherein the gripping handle portion comprises at least one open loop.
5. The protective sterility cap of claim 1 , wherein the gripping handle portion comprises a solid body without an open loop.
6. The protective sterility cap of claim 1 , in combination with a lancet having a lancet body defining a lancet thickness, and a sharp lancet tip initially embedded in the primary sheath, wherein the gripping handle portion defines a lateral span of at least 1.5 times the lancet thickness.
7. The protective sterility cap of claim 6 , wherein the gripping handle portion defines a length at least equal to its lateral span.
8. The protective sterility cap of claim 6 , wherein the gripping handle portion defines a length at least equal to the lancet thickness.
9. A protective sterility cap for a lancet, said sterility cap comprising a primary sheath for initial embedment of a sharp lancing tip of an unused lancet therein, a secondary sheath for receiving the sharp lancing tip of a used lancet, and a gripping handle portion extending between the primary sheath and the secondary sheath, with the primary sheath attached at a first end of the gripping handle portion and the secondary sheath attached at a second end of the gripping handle portion when the protective sterility cap is removed from the lancet, and wherein the gripping handle portion comprises at least one open loop.
10. The protective sterility cap of claim 9 , further comprising at least one flat display surface for placement of branding indicia thereon.
11. The protective sterility cap of claim 9 , in combination with a lancet having a lancet body defining a lancet thickness, and a sharp lancet tip initially embedded in the primary sheath, wherein the gripping handle portion defines a lateral span of at least 1.5 times the lancet thickness.
12. The protective sterility cap of claim 11 , wherein the gripping handle portion defines a length at least equal to its lateral span.
13. The protective sterility cap of claim 11 , wherein the gripping handle portion defines a length at least equal to the lancet thickness.
14. A protective sterility cap for a lancet, said sterility cap comprising a primary sheath for initial embedment of a sharp lancing tip of an unused lancet therein, a secondary sheath for receiving the sharp lancing tip of a used lancet, and a gripping handle portion extending between the primary sheath and the secondary sheath, with the primary sheath attached at a first end of the gripping handle portion and the secondary sheath attached at a second end of the gripping handle portion when the protective sterility cap is removed from the lancet, said protective sterility cap being in combination with a lancet having a lancet body defining a lancet thickness, and a sharp lancet tip initially embedded in the primary sheath, wherein the gripping handle portion defines a lateral span of at least 1.5 times the lancet thickness.
15. The protective sterility cap of claim 14 , wherein the gripping handle portion comprises at least one open loop.
16. The protective sterility cap of claim 14 , further comprising at least one flat display surface for placement of branding indicia thereon.
17. The protective sterility cap of claim 14 , wherein the gripping handle portion defines a length at least equal to its lateral span.
18. The protective sterility cap of claim 14 , wherein the gripping handle portion defines a length at least equal to the lancet thickness.
