Abstract: A safety needle and blood collection and sampling system precluding needlstick injury by contaminated needles wherein a used needle is captured immediately within its carrier upon retraction of the needle flush with the carrier. Blood sampling is effected without reverse flow through the system and without reuse or exposure of a contaminated needle. Simplified means of assembling the needle are also set forth to minimize cost with maximum reliability notwithstanding a minimum of components.

Abstract: A disposable medical needle assembly having unique insertion and removal means from tissue, including means for fully shielding the used or contaminated needle from hazardous access or exposure. Various such means are disclosed in cooperation with needle guide and manipulation means.The assembly may also be utilized in conjunction with catheter placement, blood collection, and like purposes, while maintaining full and automatic safety shielding of the needle after use.

Abstract: Sample handling apparatus includes a disposable, single use sample vessel that includes reclosable port structure, and coupling structure adjacent said port structure. Cooperating sample transfer structure for detachable connection to the coupling structure of the vessel includes a transfer passage and a port opening probe portion and is movable to a position in which the probe portion opens the reclosable port structure to provide a flow path between the transfer passage and the sample storage vessel. In that position, the vessel and sample transfer structure cooperate to define a sealed chamber that has a flexible, resilient wall.

Abstract: A micro device for collecting blood from an individual or other blood source into a blood sampler cup, which cup has a removable vented top with a capillary tube passing through the top and contacting or proximate to the inside wall of the cup to deliver blood directly from the blood source to the cup.

Abstract: Disclosure is made of a novel apparatus for the collection, separation and isolation of serum or plasma from blood obtained from mammalian capillary sources. The apparatus comprises a tubular blood collection component and an airtight closure therefor. The closure member includes a reservior and means of dispensing a thixotrope into the blood collection chamber, under centrifugal force, to effect a physical separation and isolation of the desired serum or plasma. The apparatus is advantageously employed to minimize loss of blood gases during separation and holding.

Blood sampling is effected without reverse flow through the system and without reuse or exposure of a contaminated needle. Simplified means of assembling the needle are also set forth to minimize cost with maximum reliability notwithstanding withstanding a minimum of components.
