A lancing device utilizing tail handle to load and adjust depth, includes a shell, an ejection pin, and a tail handle. The tail handle rotates fit with shell in circumferential direction of lancing device and slides fit with shell in axial direction of lancing device; the tail handle has forward sliding limit relative to shell in axial direction; passive impact surface is arranged corresponding to active impact surface on ejection pin for adjusting puncture depth and loading, and passive impact surface is formed by spiral action surface on tail handle; in use state, rotating tail handle will drive position of impact point on passive impact surface to change in axial direction of lancing device, thereby adjusting lancet tip puncture depth; pulling the tail handle backward will force the passive impact surface to come into contact with the active impact surface, and drive the ejection pin to be loaded and locked.

A tail pressing type disposable safety lancet includes a shell, a lancet core, a spring and tail cover. The shell has an elastic arm for locking the lancet core, wherein: the tail cover has an active locking part for locking and the elastic arm has a passive locking part for locking correspondingly; the positions, the fitting time of the active locking part and the passive locking part correlate with the active and passive unlocking parts; when the tail cover is pressed during use, it forces the lancet core to unlock for ejection and puncturing, and the tail cover and elastic arm enter the locking state and cannot be used again. After use of the safety lancet, the tail cover permanently locks on the elastic arm of the shell, ensuring the safety of single use, and the user visually recognizes the tail cover is retracted at the tail of the shell.

Apparatuses and methods for dried blood spot (DBS) sample collection are disclosed. A dried blood spot sampling device is configured to deliver blood through a passage to an absorbent disk in the device and control an amount of blood saturating the absorbent disk. The sampling device may include a manually actuatable component adjustable between a first position, in which an outlet of the passage is not in physical contact with the absorbent disk, and a second position, in which the outlet of the passage is in physical contact with the absorbent disk.

A lancet device includes a housing, a removable front cap mounted to the housing, a lancet holding member, a trigger and an arming system comprising a grippable cocking member structured and arranged to place the lancet device in a trigger-set or armed position. A depth adjustment system includes a member that is at least slidable and partially rotatably mounted and that has an axis of rotation arranged substantially parallel to a center axis of the lancet holding member. An ejection system includes an ejector having a portion extending outside a sidewall opening of the housing and being located closer to a front end of the housing than to a rear end of the housing. The sidewall opening of the housing is arranged on an area of the housing located between the trigger and a wall of the housing located opposite the trigger. The ejection system is structured and arranged to at least one of prevent axial movement of the lancet holding member or remove or eject a lancet from the lancet holding member.

The device is comprised of oblong main body and the cup, which locks the front end of the main body. A casing of the main body is shaped as a tube. A puncture mechanism with a lancet leading unit, a puncture depth regulation mechanism and used lancet removal mechanism are installed in the casing. They compose a mechanism unit, which components are installed in a mechanism body, fastened inside the casing. The lancet leading mechanism is comprised of a lancet socket with guide, that goes through the opening in the transversal partition of the mechanism body, and lancet chamber. The guide is linked with the front end of a driving sleeve, sliding and rotary fitted in the mechanism body. Between the transversal partition and the driving sleeve there is the return spring. Between the driving sleeve and a button there is the drive spring. At the end of the casing there is the button, sliding and rotary fitted. The tension in the drive spring is released by a springy latch of the driving sleeve, that cooperates with a stop surface of the mechanism body and an activating surface of the button. The puncture depth regulation mechanism is comprised of the button rotary coupled with the driving sleeve and limiting steps limiting the movement of a bumper of the driving sleeve.

A vacuum assisted lancing system can include a tubular body having a vacuum chamber, a lancing mechanism configured to removably couple with a lance, a vacuum mechanism including a piston slideably coupled within the body, a release mechanism for selectively holding the vacuum mechanism in an energized state and an opening for allowing fluid communication between the vacuum chamber and an atmosphere. A method of manipulating a surface for blood extraction can include coupling a lancing system to the surface, blocking an opening, creating a vacuum, moving a lance coupler from a first position distal from the surface to a second position proximal to the surface, maintaining the vacuum for a period of time and commencing dissipation of the vacuum by unblocking the opening.

This disclosure provides equipment and processes for blood glucose management. Embodiments may comprise a lancet device that includes a base that supports a lancet and a cover. The cover can move controllably from an un-depressed position to a depressed position when a predetermined force is applied. The cover can provide access to the lancet in the depressed position. In another aspect, a biological test kit may include a reusable module and a disposable module. The disposable module may include one or more lancet devices such as that described above to collect a biological sample, one or more strip stations supporting biological strips and a disposable module connector. The reusable module may support measuring equipment to measure a property of the biological sample and a reusable module connector that engages removably with the disposable module connector.
