METHOD AND MACHINE FOR COLLECTING BIOLOGICAL FLUID TO WHICH A SOLUTION ACCORDING TO A DESIRED RATIO IS ADDED

Lancet device

The 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 wherein the puncturing element is retained within the housing, and a puncturing position wherein 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 where 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.

lancet, manufacturing method and plurality of lancets

Expõe-se uma lanceta que compreende uma agulha; um corpo para reter a agulha; e uma tampa para proteger pelo menos a ponta da agulha; sendo que pelo menos um do corpo e da tampa é moldado, em que o corpo e a tampa são ligados entre si durante a moldagem do corpo ou da tampa, e em que, na interface entre o corpo e a tampa, a força de ligação por unidade de área é menor do que dentro do corpo e da tampa. Isto permite que a tampa seja facilmente puxada fora em vez de ser arrancada torcendo. Expõe-se igualmente uma lanceta que compreende: uma agulha; um corpo para prender a agulha; e uma tampa para proteger pelo menos a ponta da agulha; em que o corpo é dotado de uma primeira formação de enganche e a tampa é dotada de uma segunda formação de enganche, em que as formações de enganche são proporcionadas de forma tal que, uma vez que a tampa foi removida do restante da lanceta, as formações de enganche podem ser configuradas de maneira a encaixar uma com a outra, de modo que a tampa é suportada pelo corpo. Se for proporcionada uma pilha de tais lancetas, a tampa da primeira lanceta pode ser suportada pelo corpo da lanceta seguinte e assim por diante. A lancet comprising a needle is exposed; a body for retaining the needle; and a cap to protect at least the needle tip; wherein at least one of the body and cap is molded, wherein the body and cap are bonded together during molding of the body or cap, and wherein at the interface between body and cap the bonding force per unit area is smaller than inside body and cover. This allows the lid to be easily pulled off rather than torn off by twisting. Also exposed is a lancet comprising: a needle; a body for holding the needle; and a cap to protect at least the needle tip; wherein the body is provided with a first hook formation and the lid is provided with a second hook formation, wherein the hook formations are provided such that once the lid has been removed from the rest of the lancet, the hook formations may be configured to ...
