A lancet magazine is disclosed which includes a housing and a plurality of lancets each of which is enclosed in a sterile chamber of the housing, wherein the chambers each have a puncturing opening which is closed with a foil, wherein the lancets include a sample receiving device for receiving body fluid and the chambers each include a further opening which is closed with a membrane that is permeable to gas and fluid and includes a lower side that faces the lancet and serves to receive body fluid from the sample receiving device and an upper side that serves to transfer body fluid to a test field arranged on the membrane.

A lancing device having a housing with a proximal end, a distal end and a longitudinal axis. The lancing device also has a lancet carrier translationally supported with respect to the housing. The lancet carrier has a proximal end and a distal end. The lancing device additionally has a charging mechanism and/or an ejection mechanism adapted to pivot into the lancing device for engaging portions of the lancet carrier to perform the same.

A blood collection device includes a housing and an interface. The blood collection device includes at least one blood collection container engaged with the interface and at least one lancet coupled to the interface. The at least one lancet extends or is configured to extend from the interface. The at least one lancet is configured to pierce tissue. The blood collection device also includes an absorbent material integrated with the housing. The absorbent material is configured to absorb fluids emanating from the tissue after the at least one lancet pierces the tissue.

The disclosed apparatus, systems and methods relate to devices, systems and methods for the collection of bodily fluids involving a single-use actuation and retraction mechanism disposed within a collector.

Devices are provided to automatically access blood from beneath or within skin. These devices include an injector configured to drive a needle into the skin and subsequently to retract the needle from the skin. These devices additionally include a seal to which suction is applied. To drive the needle into the skin, the needle is first driven through the seal, creating at least one hole in the seal. The suction applied to the seal acts to draw blood from the puncture formed in the skin by the needle, through the at least one hole in the seal, and to a sensor, blood storage element, or other payload. These devices can be wearable and configured to automatically access blood from skin, for example, to access blood from the skin at one or more points in time while a wearer of a device is sleeping.

An apparatus for eliciting a blood sample comprises a housing, an aperture in a wall of the housing, an aperture cover moveable between a first position in which the aperture is covered and a second position in which the aperture is uncovered, the aperture cover comprising a sealing member configured to seal the aperture on a first side of the wall when the aperture cover is in the first position and a user-contactable part extending from the sealing member through the aperture to the second side of the wall and configured to allow a user to move the aperture cover between the first and second positions.

A method of performing an intravenous drip injection includes a first step, a second step, a third step and a fourth step. A first step includes starting dosing an infusion solution containing a predetermined component by the intravenous drip injection to a dosing recipient. A second step includes extracting a body fluid from the dosing recipient being dosed with the infusion solution. A third step includes measuring a concentration of the predetermined component in the extracted body fluid. A fourth step includes varying the concentration of the predetermined component in the infusion solution, corresponding to the concentration of the predetermined component in the body fluid.

Provided is a lancing device including a casing, a launch part, and a bumper part wherein the bumper part comprises a needle body holder, a cylindrical bumper and bump spring; and a disposable painless lancet for use with the device. The disposable painless lancet and lancing device according to the present invention are figured such that a bump spring strikes the skin in advance before the needle penetrates the skin, disturbing the skin nerve, and such that a needle of the lancet can be allowed to be inserted only a certain depth of skin, thus the subject does not feel any pain at all.
