A pressing type disposable safety lancet with spring pilot structure consists of a shell, a lancet core, a spring and a trigger. The spring with a pilot structure at the outside makes the elastic force of the spring act along the ejection direction of the lancet core; the locking mechanism is formed by the cooperation of the elastic clamp at the tail of the trigger and the lancet core; the unlocking mechanism is formed by the front of pilot structure and the end of the elastic clamp through the unlocking bevel; when it's pressed during the use, the trigger moves backwards in the shell, the front of the pilot structure forces the end of the elastic clamp to open under the action of the unlocking bevel, and the lancet core is fired for puncturing under the action of the spring after the hook unhooks from the locking critical point.

Provided is a lancet which comprises: a housing provided with an inner sleeve guiding portion and a first needle core guiding portion; an inner sleeve provided inside the housing; wherein the front end of the inner sleeve has an inner sleeve needle outlet, and the inner sleeve is provided with a second needle core guiding portion; a needle core adapted to move axially along the first needle core guiding portion; a spring provided inside the housing to drive the needle core, wherein the inner sleeve guiding portion has a radial rotation angle at a rotation guiding section thereof away from the inner sleeve needle outlet; by pressing towards the inside of the housing, the inner sleeve is guided by the rotation guiding section to rotate such that the first needle core guiding portion is aligned with the second needle core guiding portion in the radial direction.

An integrated blood test unit including a blood collection recess, a test component, and a reservoir containing test fluid. The blood collection device moves to a delivery position under control of an actuator, which also releases test fluid from the reservoir onto the test component. Additional features are a window over the test outcome indicator, a blood delivery channel that only operates if the sample size is large enough, and a geometry for a lancet and actuator that is adapted for a self test situation.

Devices and methods for withdrawing bodily fluid from a patient are disclosed herein. A handheld device configured in accordance with the present technology can include a housing having an opening, a skin-piercing assembly located at least partially within the housing, and an actuator movable relative to the housing along a deployment direction. The skin-piercing assembly can include a skin-piercing feature and a biasing member. The biasing member can be coupled to the skin-piercing feature to bias the skin-piercing feature along the deployment direction. Movement of the actuator along the deployment direction to a predetermined position can increase a load on the biasing member to at least a partially loaded state. Movement of the actuator along the deployment direction beyond the predetermined position can release the load on the biasing member so that the biasing member actively drives the skin-piercing feature along the deployment direction.

An apparatus for insertion of a medical device in the skin of a subject is provided, as well as methods of inserting medical devices.

An apparatus for insertion of a medical device in the skin of a subject is provided, as well as methods of inserting medical devices. Embodiments include removing a substantially cylindrical cap from an inserter to expose a substantially cylindrical sleeve, removing a cover from a substantially cylindrical container holding sensor components, and fitting the sensor components into the inserter.

A system for extracting and collecting a sample of a fluid of a user, comprising a sample collection device, comprising a sample container arranged to receive said sample; a cap arranged to cooperate with the sample container and having an incision mechanism movable in the cap by a triggering mechanism; a sealing mechanism; a sample extraction device, comprising a vacuum creation mechanism arranged to create vacuum in a vacuum chamber; and a valve control mechanism arranged to release the vacuum from the vacuum chamber to the sample collection device. The system simplifies collection of a fluid (e.g., blood) sample while keeping a high-quality standard for its analysis, minimizes the risk of injury due to handling the sample, reduces the risk of contamination of the collected sample, is compatible with standard blood analysers of central laboratories, requires minimal action from the user, and can collect large volumes of bodily fluid.

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.
