A safety blood-collection needle, comprising a needle base, a needle hub, a flexible tube, a straight needle, a straight needle shaft, and a needle head; the safety blood-collection needle further comprises a protective cover, a slider, a handle, and a position limiting mechanism; one end of the needle base is fixed and is in communication with the needle head; the slider movably sleeved on the needle base; the position limiting mechanism is arranged on the slider and needle base. The slider is arranged on the needle base and slides in order to cover the needle head, so that safety is greatly increased when handling the needle head following blood collection; the use of a spring-type needle head is avoided, thus reducing the suffering of the patient.

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.

A needle assembly includes a housing having proximal and distal ends, an IV cannula projecting distally from the housing, and an IV shield having an engagement. The housing has a shield seat and the IV cannula has a distal tip. The IV shield has a pre-use position where the IV shield covers the distal tip of the IV cannula and the engagement is disengaged from the shield seat, and a use position where the engagement is engaged with the shield seat and the IV shield is adapted to move between a non-shielded position, in which the distal tip is exposed, and a shielded position, in which the distal tip is shielded by the IV shield.

A microperfusion needle or fistula needle with a protective element comprises a first component comprising a cannula, a body rigidly joined to the cannula, and having grasping wings extending therefrom, a second component comprising an elongate body having a cavity for slidably receiving the first component between an operating position of the cannula and a safety position of the cannula, the elongate body having lateral slots for the grasping wings to extend therethrough, the grasping wings being suitable for elastically bending around and contacting opposed portions of the elongate body. The elongate body comprises two arrays of projections, which are contacted by the wings when bent. Opposed pairs of projections are designed to contact and mechanically interfere with the grasping wings when bent.
