Abstract
The device is built of a housing (1), wherein a push button (3) is positioned, and the puncturing needle (5), wherein the push button (3) has arms (7, 8) to guide the push button (3) inside the housing (1), and a driving spring (11), one end of which is linked to the push button (3), and the other end drives the puncturing needle (5), and the puncturing needle (5) has breakable wings (17, 18), which rest against the breaking edge (19) of the housing (1). The device has moreover two return springs (13, 14), each of which is connected to one of the arms (7, 8) of the push button (3), and two side juts (15, 16), each of which is positioned between one of the return springs (13, 14) and the other end of the driving spring (11).
Claims20
A puncturing device comprising:
- a housing, wherein the housing defines a breaking edge;
- a puncturing needle disposed in the housing, wherein the puncturing needle has breakable wings that rest against the breaking edge of the housing, and at least one side jut;
- a push button disposed in the housing, wherein the push button has arms to guide the push button inside the housing;
- at least one return spring, wherein each of the at least one return spring is directly connected to an arm of the arms, and wherein the at least one return spring has a contact portion that contacts the at least one side jut;
- and
- a driving spring having a first end and a second end, wherein the first end is linked to the push button and the second end drives the puncturing needle in a driving direction parallel to a longitudinal axis defined by the puncturing needle,
- wherein the entirety of the at least one side jut of the puncturing needle is disposed inside the housing longitudinally between the contact portion of the at least one return spring and the second end of the driving spring before, during, and after use of the puncturing device, such that the contact portion of the at least one return spring, the entirety of the at least one side jut, and the driving spring are disposed in non-overlapping series along the longitudinal axis before, during, and after use of the puncturing device, and
- wherein the at least one return spring acts against the at least one side jut in a direction generally opposite to the driving direction.
A puncturing device comprising:
- a housing, wherein the housing defines a breaking edge;
- a puncturing needle disposed in the housing, wherein the puncturing needle has an upper pushing end and a lower puncturing end, wherein the puncturing needle defines a longitudinal axis along which the puncturing needle travels, and wherein the puncturing needle comprises:
- an elongated body extending longitudinally;
- a breakable wing protruding from the body in a direction perpendicular to the longitudinal axis, wherein the breakable wing rests against the breaking edge of the housing before use of the puncturing device, and
- a jut member protruding from the body in the direction perpendicular to the longitudinal axis,
- wherein the breakable wing is disposed closer to the puncturing end than the jut member, and
- wherein the jut member defines a lower contact face facing the puncturing end of the needle and an upper face opposite to the lower contact face;
- a push button disposed in the housing, the push button comprising:
- a button face extending in a direction perpendicular to the longitudinal axis and disposed over the upper pushing end of the puncturing needle,
- an arm extending from the button face in a direction toward the lower puncturing end of the puncturing needle and parallel to the longitudinal axis, wherein the arm guides movement of the push button within the housing, and
- a return spring directly connected to the arm, the return spring defining an upper contact surface that contacts the lower contact face of the jut member;
- and
- a driving spring disposed between the button face of the push button and the pushing end of the puncturing needle, wherein the driving spring is discontinuous with the puncturing needle, and
- wherein before, during, and after use of the puncturing device, the lower contact surface of the jut member faces the upper contact surface of the return spring.
