Abstract
A lancing device having a domed structure that can be depressed by application of a force by a user's finger so as to expose the tip of a needle. The domed structure is configured to move from a non-depressed state to a depressed state in a manner that allows for the piercing the users finger. The domed structure may then recoil to its original, non-depressed position upon the user ceasing to apply the force.
Claims20
A lancet device comprising:
- a base;
- a needle having a tip and having a position relative to the base;
- a flexible member having an aperture;
- and
- wherein the flexible member is arranged relative to the needle so that when a sufficient force is applied to the flexible member, the flexible member transitions from a first configuration to a second configuration, and wherein the tip of the needle protrudes from the aperture of the flexible member while the flexible member is in the second configuration.

A lancet device comprising:
- a base;
- a needle having a tip;
- a cartridge in which the needle resides, the cartridge being configured so as to allow the needle to move along the axis of the needle relative to the base;
- a flexible member having an aperture, the flexible member being arranged in a first configuration relative to the base;
- wherein when a sufficient force is applied to the flexible member, the flexible member transitions from the first configuration to a second configuration;
- wherein when the force ceases to be applied, the flexible member returns to the first configuration;
- and
- wherein the flexible member returning to the first configuration causes the needle to move relative to the base so as to allow the tip of the needle protrude from the aperture of the flexible member.
5 more elements
A lancet device comprising:
- a base;
- a needle having a tip;
- a button having an aperture, the button being arranged within the base so that it may move parallel to the axis of the needle, the button having a top surface that is exposed from the base;
- a flexible structure having a middle portion and an outer portion, the flexible structure being arranged relative to the button in a first configuration so as to create a cavity in which the needle resides;
- wherein when a sufficient force is applied to the top surface of the button, the button will apply force on the outer portion of the flexible structure, causing the flexible structure to transition from the first configuration to a second configuration in which the tip of the needle protrudes from the aperture of the button.
