An automatically locking safety device, e.g., for use in a blood collection procedure, can include a housing, first and second needle covers that are at least partly received in the housing, and a needle that is at least partly received in at least one of the first and second needle covers. The needle can include a proximal tip configured for placement into a patient and a distal tip configured for placement into a blood collection vial. In some embodiments, the first and second needle covers are biased by a biasing member. In some cases, one or both of the first and second needle covers can be locked to prevent axial movement thereof after the blood collection procedure. In certain embodiments, a distal end of the device is configured to connect with a medical connector, such as a needleless IV access device.

A lancet pricking device comprises a lancet, a launching spring, a trigger part and a holder housing the lancet, launching spring and trigger part. The lancet comprises a lancet body, lancet cap and pricking needle. The pricking needle is in both the lancet body and lancet cap. The trigger part has a pair of arms positioned inside the holder. The launching spring is attached to the lancet body. The lancet body is secured to the arms of the trigger part by an abutment of the lancet body on the arms such that the launching spring is compressed before a pricking operation. The trigger part cannot be pushed toward the inside of the holder before the lancet cap is removed, but can be pushed toward the inside of the holder after the cap is removed. The lancet body warps when pressed to release the secured lancet body.

The disclosed apparatus, systems and methods relate to devices, systems and methods for the collection of bodily fluids involving a single-use actuation and retraction mechanism disposed within a collector.

A puncture needle cartridge (1) includes: a lancet body (5) mounted with a puncture needle (3) on a front end side and having a mount (4) on a rear end side; and a plate-like first case (6) and second case (7) covering the lancet body (5) from above and below and arranged slidably back and forth along each other. The puncture needle cartridge (1) is configured such that the first case (6) is slid forward of the second case (7), and in this slid state, the first case (6) and the second case (7) are secured to each other when ejected from the puncture instrument (10). This can make the puncture needle cartridge (1) impossible to mount again on the puncture instrument (10).

An infant peripheral lancing device having safety buckle turn lock and anti-backward push button, wherein the safety mechanism is a safety buckle rotationally connected on a housing, and the first occupation gesture of the safety buckle during movement is between a push button and the housing and locks the push button; the second occupation gesture is in unlocking position. The push button is set with a locking mechanism, which comprises a first locking part on the push button and a second locking part on the housing or the cam and when the push button is moved backward, the first locking part and the second locking part meet to form a locking state. This solution always connects the safety buckle and the housing to prevent an accidental disconnection or loss and the lancing device present invention locks the push button automatically after using to make it easy for the user to identify the state of the push button.

A lancet pricking device comprising a lancet, a launching spring and a lancet holder for housing therein the lancet and the launching spring. The lancet pricking device of the present invention is characterized in that the lancet comprises a lancet body, a lancet cap and a pricking needle, and the pricking needle is disposed in both the lancet body and the lancet cap; wherein the launching spring is attached to the lancet body, and the lancet body is secured by abutting against the lancet holder such that the launching spring is kept compressed before a pricking operation; and wherein, when the lancet cap is removed, the lancet body becomes capable of warping upon being pressed from an outside to cause the secured lancet body to be released.

A disposable automatic painless safe hemostix includes an outer casing, an inner sleeve, a needle module and a spring. The needle module is snapped in the inner sleeve and the outer casing. The needle module has a needle point protecting pole. Interlock fixing faces and protrusions are provided on the inner sleeve. Interlock guiding slopes and protrusion stoppers are provided on the inner wall of the outer casing. One end of the interlock engages the interlock fixing face, and the other end engages the interlock guiding slope.
