Claims20
A needle assembly comprising:
- a needle, wherein the needle defines an axial direction and wherein a tip of the needle is more proximal than the rest of the needle and a radial direction perpendicular to the axial direction;
- a needle housing comprising a cavity and wherein the cavity is occupied in part by the needle;
- wherein the needle housing further comprises a proximal portion and wherein the proximal portion is more proximal than the rest of the needle housing;
- wherein the proximal portion protrudes proximally beyond the tip of the needle.
A connection assembly configured to facilitate introducing a fluid from a needle to a fluid conducting element, comprising a needle assembly and a needle receiving assembly;
- wherein the needle assembly comprises:
- a needle, wherein the needle defines an axial direction and wherein a tip of the needle is more proximal than the rest of the needle and a radial direction perpendicular to the axial direction;
- and
- a needle housing comprising a cavity and wherein the cavity is occupied in part by the needle;
- wherein the needle housing further comprises a proximal portion and wherein the proximal portion is more proximal than the rest of the needle housing;
- wherein the proximal portion protrudes proximally beyond the tip of the needle;
- wherein the needle receiving assembly comprises the fluid conducting element;
- wherein the needle assembly and the needle receiving assembly are configured to be connected for introducing the fluid from the needle to the fluid conducting element.
A system comprising
- a sampler configured to pick up a fluid, wherein the sampler comprises a needle assembly;
- wherein the needle assembly comprises:
- a needle, wherein the needle defines an axial direction and wherein a tip of the needle is more proximal than the rest of the needle and a radial direction perpendicular to the axial direction;
- a needle housing comprising a cavity and wherein the cavity is occupied in part by the needle;
- wherein the needle housing further comprises a proximal portion and wherein the proximal portion is more proximal than the rest of the needle housing;
- wherein the proximal portion protrudes proximally beyond the tip of the needle.
