Abstract:
PROBLEM TO BE SOLVED: To solve the tips of the lancets are erected prior to a puncture, for example by swiveling them out of the plane of the wheel, in this context, high precision is required in order for the lancet puncture to be associated with little pain, and moreover, erecting the lancet tips should be feasible with as little effort as possible to allow this to be performed in a compact puncturing device. SOLUTION: In the lancet wheel (1) having a plurality of lancets (2) in a ring-shaped arrangement, the lancets (2) includes a lancet body (4) that ends in a lancet tip (3). The lancet wheel (1) has a carrier (5) that carries the lancets (2), whereby the lancets (2) are connected to the carrier (5) via bars (7, 7a, 7b, 7c) that allow for mobility of the lancets (2) relative to the carrier (5).

PROBLEM TO BE SOLVED: To provide a microdialytic system that assures prescribed highly reliable dialytic functions. SOLUTION: A microdialytic system that can be inserted in an in vivo tissue 10 is equipped with a microdialysis probe 12 having a dialysis membrane for separating a probe route 18 filled with a perfusate from the in vivo tissue, a sensor cell 14 for electric chemical measurement of elements contained in the perfusate, specifically glucose, to be transferred from the microdialysis probe 12 and a transport device 16 that transports the perfusate to the sensor cell 14 through the microdialysis probe 12, whereas the transport device 16 is provided with a delivery pump unit 30 connected with an entrance 20 of the probe route 18 on the delivery side, and a suck up pump unit 31 connected with an exit 24 of the probe route 18 on the sucking side that simultaneously operates with the delivery pump unit 30.
Abstract:
The invention relates to a piercing system for producing a puncture wound which enables to pick up a body liquid sample and comprises a pressure part (4) applicable to a body part (32) in which the puncture wound is producible, a triggering element (8) whose operation enables a user to trigger a puncture movement of a puncture element (3) after pressing the pressure part (4) and a checking device (5,15,20) for determining at least one parameter dependent on the sampling probability. According to said invention, a security device (9) is used for locking the triggering element (8) in the locking state in such a way that no puncture movement is triggered and for releasing said triggering element (8) in the triggering state in such a way that the puncture movement is triggered, wherein the security device (9) is transferred from the locking state to the releasing state by the action of the checking device (5,15,20) when the checking parameter determined thereby satisfies the minimum predetermined requirements, the puncture system also comprises a signalling device (12) for signalling the transition of the security device (9) to the triggering state and/or for signalling that said device is in the triggering state. A method for preparing the puncture system for producing a puncture wound is also disclosed.
Abstract:
The invention relates to a lancet having a flat shaft (1) which has an upper side (1c) and a lower side (1b), the shaft (1) forming at a front end (2) a cutter (1a) which ends in a point (2), the cutter (1a) having on the underside (1b) two cutting edges (4), which run together at the point (2), and the shaft (1) having at least one depression (3) on its underside (1b) to receive a sample. The invention provides for the shaft, on its upper side (1c), to merge into the cutter (1a) at two edges (5) which run together at a vertex (6), and for the upper side (1c) of the cutter (1a) between the vertex (6) and the front end (2) to be curved convexly, as seen in cross section.
Abstract:
The invention relates to a piercing system for removing bodily fluid from the skin of a human or animal. Said system comprises a disposable piercing unit (1), which contains a needle element (6) for puncturing the skin, a piercing device (2), which encompasses a piercing drive (4), said drive propelling a piercing displacement of the piercing unit (1), which is coupled to the piercing drive (4) by means of a coupling mechanism (3), a predefined value of the piercing depth being guaranteed using a piercing depth reference element (10), which comprises a skin contact surface (11) and the predefined value of the piercing depth being determined by the distance in the piercing direction between the skin contact surface (11) and the position of the needle tip at the inversion point of the piercing displacement. The piercing depth reference element (10) is connected to the needle element (6) and coupled to the drive in such a way that it is displaced together with the needle element (1) during at least one part of the propulsion phase and has a defined longitudinal position in the piercing direction in relation to the needle element (6), at least at the inverse point of the piercing displacement.
Abstract:
Instrument for producing a sample of body liquid for analysis by piercing the skin with a lancing element (12) having a skin piercing tip. The instrument (11) has a housing (13) and a lancing drive (14) for driving a lancing element (12) connected thereto in a puncturing movement. A pressure ring (1) surrounds a skin contact opening (4) and is adapted for pressing against the skin such that the skin (3) bulges into the opening (4) for promoting expression of body fluid. The skin contact opening (4) has an opening area corresponding to a circle with a diameter of at least 3 mm and at most 8 mm, and the instrument comprises a pressing force control device (37) for controlling the pressing force between the pressure ring (1) and the skin (3) at the time of triggering the puncturing movement, to be at least 3 N and at most 8 N.
