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.

A device (1) for obtaining a biological sample that includes a blood collection device (10) and a vibration device (80) removably attachable to the blood collection device that provides pain relief is disclosed. The vibration device of the present disclosure provides pain relief to a patient by vibrating the blood collection device. The vibration device can be attached to the blood collection device before it is placed onto a finger to provide pain relief during the finger lancing as well as to aid blood flow from the finger into a collection container during the collection process.

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 assembly for sampling bodily fluid, the assembly comprising a membrane penetration device comprising a membrane penetrating element for penetrating a bodily membrane to release a bodily fluid; and, a collector configured in a collection position to take up the released bodily fluid and retain the fluid for delivery to a test element.

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.
