Passive double drive member activated safety blood collection device

A shieldable needle device including a drive member is disclosed. The drive member is extendable between a biased position and an extended position for moving a tip guard from an first position to a second position in which the tip guard shields a distal end of the needle cannula. The shieldable needle device includes a pair of wings extending laterally from opposing sides of the hub that are movable between a laterally extending position and a dorsal position. With the wings in the dorsal position, the wings retain the drive member in the biased position thereby maintaining the tip guard in the first position. Movement of the wings from the dorsal position to the laterally extending position releases retainment of the drive member. A second drive member may be included.

Blood sequestration device and method

A blood sequestration device configured to isolate an initial, potentially contaminated portion of blood from the flow of blood of a patient, prior to directing the flow of blood to an outlet port where the blood can be accessed. The blood sequestration device including a body member having an interior wall defining a fluid conduit having a distal portion, a first proximal portion, and a second proximal portion, wherein the first proximal portion defines a sequestration chamber configured to isolate an initial portion of blood of a flow of blood, a vent path configured to enable the escape of gas initially trapped within the sequestration chamber.

DRUG ADMINISTRATION DEVICE

A device which, in a shallow region including the epidermal layer or the dermal layer, can administer a target even in extremely small amounts. This includes a puncture needle which, in a flat puncture unit for puncturing the shallow region, has a groove and a through-hole which constitute a recess that extends through part of or the entire thickness of the puncture unit; and a casing which houses the puncture needle so as to allow the puncture needle to advance. By part or all of a flow agent containing the drug being arranged in the groove and the through-hole, the drug is positioned with respect to the puncture unit. The device is designed such that a flow agent in the amount of 10-1000 nL is dosed in the shallow region per puncture.

AUTOMATED MEDICAL SAMPLE COLLECTION AND TESTING FOR PROVIDING BLOOD COAGULATION INDICATION
20220378345 · 2022-12-01 · ·

A sample collection and testing device for analyzing blood is provided that includes a controller, a fluid flow pathway, a pump configured to move fluid through the fluid pathway, and an optical fluid measurement element configured to measure a light intensity of the fluid in the fluid flow pathway. The controller is configured to: start the pump to move a blood sample in the fluid flow pathway, receive a signal from the optical fluid measurement element indicating a detection of a leading edge of the blood in the fluid flow pathway, stop the pump to stop the moving of the blood in the pathway, receive a plurality of light intensity measurements from the optical measurement element, each light intensity measurement measured at a corresponding point of time, and provide a mapping of the light intensity measurements into an indication of a coagulation of the blood sample over a time period.

Lancing device

A lancing device has a domed structure that can be depressed by application of a force by a user's finger so as to expose the tip of a needle. The domed structure is configured to move from a non-depressed state to a depressed state in a manner that allows for the piercing of the user's finger. The domed structure may then recoil to its original, non-depressed position upon the user ceasing to apply the force. Other embodiments of a lancing device are disclosed.

CANNULA INSERTION SYSTEM

A cannula insertion system for inserting a cannula into a human or animal body, includes a cannula and a cannula insertion device to hold and insert the cannula into the human or animal body in an insertion direction. The cannula insertion system includes a safety device configured to retract the cannula or to release the cannula from the cannula insertion device when a force exerted on the cannula in a direction perpendicular to the insertion direction results in exceeding a respective safety threshold value.

CANNULA INSERTION SYSTEM
