摘要:
A lancing apparatus for producing a puncture wound, comprising a magazine holder for a lancet magazine with a plurality of lancets. The lancet drive comprises a drive spring, a tensioning device for tensioning the drive spring and a push rod, the push rod being adapted for coupling to a lancet located in the lancet magazine and being adapted for moving at high velocity, together with a lancet coupled thereto, by means of lancet drive during a puncture and retraction movement to produce a puncture wound. A magazine advancing mechanism is provided for advancing the lancet magazine in such a manner that the lancets stored therein can be coupled to the push rod one after the other. According to exemplary embodiments, the lancet drive is not mechanically coupled to the magazine advancing mechanism whereby a plurality of puncture wounds can be produced using the same lancet a plurality of times. The lancing apparatus compromises an actuating element for actuating the magazine advancing mechanism independently from the lancet drive, in particular for actuating it independently from the tensioning device.

A lancing system can include a device body having a sealing device coupled to a lancing end, a lancing shaft slideably coupled to the lancing end, a lancing spring coupled to the lancing shaft, a release mechanism, a main shaft slideably coupled with a free end of the device body in communication with the release mechanism, a piston coupled to the main shaft, a vacuum spring coupled to the piston, and a shaft coupler having at least two separable portions for removably coupling the lancing shaft to the main shaft. The system can include a lance tool having an insertion portion and a removal portion. A method can include creating a first portion of a vacuum, lancing a surface, and creating a second portion of a vacuum.

A needle assembly is provided with the housing, and IV cannula for accessing a blood vessel and a non-patient cannula for communication with an evacuated tube. A flashback chamber is provided in the housing at or near the distal end of the housing. A shield is hinged to a portion of the assembly proximally of the entrance to the flashback chamber. As a result, good visibility of the flashback chamber is achieved. After use, the shield can be rotated into a closed portion for surrounding the IV cannula and avoiding accidental needle sticks.

Lancet device that includes a body. A front cover includes a skin engaging end that includes a lancet opening through which a lancet needle extends. A holding member is movably mounted within the body. The holding member includes a front end and a rear end. The front end is configured to receive a lancet. A main spring is disposed between the front and rear ends of the holding member. A first stop surface is arranged on a front portion of the holding member. A second stop surface is axially retained to a front portion of the body. At least partial rotation of the front cover causes the skin engaging end to move axially relative to the second stop surface.

These and other objects of the present invention are achieved in a body fluid sampling system for use on a tissue site that includes a single drive force generator. A plurality of penetrating members are operatively coupled to the force generator. The force generator moves each of the members along a path out of a housing with a penetrating member exit, into the tissue site, stops in the tissue site, and withdraws out of the tissue site. A flexible support member couples the penetrating members to define a linear array. The support member is movable and configured to move each of the penetrating members to a launch position associated with the force generator. A user interface is configured to relay at least one of, penetrating member performance or a penetrating member setting.

A tissue penetration device includes a penetrating member driver, a cartridge, and a plurality of penetrating members integrated with the cartridge. Each of a penetrating member is coupled to the penetrating member driver when advanced along a path into a tissue target. A user interface is configured to relay at least one of, skin penetrating performance or a skin penetrating setting.

A lancing device is provided for use with a removable lancet. The lancing device includes a housing and a lancet carrier slidably disposed within the housing and adapted to receive the lancet. A user-actuated ejection slide is mounted to the housing to eject the lancet from the lancet carrier. A locking member is pivotally mounted to the housing. As the ejection slide moves forward, it rotates the locking member to block forward movement of the lancet carrier during ejection. The locking member is configured so that substantially all of the force exerted on it by the lancet carrier is transmitted to the housing via the pivotal mounting.
摘要:
A blood testing device in which a blood sensor does not contaminate a piercing section when discarded. The blood testing device (11) is provided with the piercing section (13) having an upper holder (13a) and a lower holder (13b), and also with a connector (18). In piercing operation, the connector (18), the upper holder (13a), and the lower holder (13b) sandwich and hold the sensor (24). To discharge the sensor, the lower holder (13b) is pivoted so as to be separated from the upper holder (13a), which creates a space between the lower holder (13b) and the upper holder (13a) to expose the sensor (24).
摘要:
A puncturing device for generating a puncture wound to sample a body fluid is provided and comprises a press-on part or contact element to be pressed against a body part to generate a puncture, a test sensor for measuring a test parameter value, and an analytical unit for determining whether the value of the measured test parameter satisfies a predefined minimum requirement for successful sampling. In one embodiment, the value of the test parameter is monitored during a waiting period by the test sensor once the value satisfies the predefined minimum requirement. After the waiting period has elapsed, so long as the values of the test parameter monitored during the waiting period are in a range of values that predicts sampling to be successful, the analytical unit initiates a puncture.
