Provide is a blood collection container capable of suppressing the occurrence of blood clots involving bubbles when blood containing heparin is coagulated, and capable of suppressing the production of fibrin in serum after separation when blood containing heparin is separated into serum and blood clots. A blood collection container according to the present invention includes: a blood collection container main body having an opening at one end thereof and a closed bottom at the other end thereof; a serine protease disposed in the blood collection container main body; and a heparin neutralizing agent disposed in the blood collection container main body, wherein when a region in which the serine protease is disposed is defined as a first region, and a region in which the heparin neutralizing agent is disposed is defined as a second region, the second region includes a region present on an other end side with respect to an end on the other end side of the first region.

A syringe for obtaining a target volume of blood is presented. The syringe (1) comprises a barrel (2), wherein a plunger (4) is arranged within the barrel (2) to be displaceable along a displacement direction (X). Furthermore the barrel (2) and the plunger (4) together provide for a first stop (20) and second stop (22), wherein the first stop (20) is configured for positioning a filter (100) at a predetermined location along the displacement direction (X) thereby defining a target volume of blood and a buffer volume. Moreover, the second stop (22) is configured to stop the plunger (4) from expelling more than the buffer volume from the syringe (1) for obtaining the target volume of blood when the plunger (4) is pushed towards the distal end (30) of the syringe (1) along the displacement direction (X). In addition, the syringe (1) facilitates that the syringe (1) fills itself with the target volume of blood by a self-filling procedure using blood that is under pressure, like arterial blood, and using the filter (100) located in the plunger (4).

A primer may be used with IV catheter systems. The primer may be positioned along the tubing of an extension set such that the primer divides the IV catheter system into a downstream portion and an upstream portion. The primer may vent air from both the upstream and downstream portions to allow blood to flow up to the primer while also allowing priming solution to flow down to the primer. As a result, the catheter may be inserted into the patient's vasculature without first priming the catheter. Once the air has been vented from the upstream and downstream portions of the IV catheter system, the primer may be actuated to open a fluid pathway through the primer. With the fluid pathway opened, the priming solution may commence flowing towards the patient's vasculature thereby flushing the blood from the IV catheter system.

Provided herein are materials and methods relating to cell-free DNA. In particular, the technology relates to methods and materials for the preparation and handling of blood samples for future use in applications involving cell-free DNA.

A secure specimen sample bottle includes a base container for receiving a specimen. The base container has a plurality of locking protrusions formed along an inner surface of the base receptacle. A bottle includes a lock ring that has an upright spire structure that has a closed top end and the opposing open bottom end including a plurality of flexible fins that are configured to interlockingly mate with the locking protrusions so as to prevent removal of the lock ring relative to the base container upon engagement of the flexible fins to the locking protrusions. A removable cap is coupled to the lock ring.

A medical device configured as a tube holder for use in collecting bodily fluids, especially for use as a blood collection tube holder, the device embodying two coaxially alignable needles, the first needle being a forwardly facing fluid collection needle and the second needle being a rearwardly facing fluid discharge needle. The first and second needles are satisfactorily supported by a frontal attachment and body, respectively, that are disposed in relative sliding engagement along an interface that is transverse to the first and second needle and that extends at least from the second needle to an opening into a needle retraction chamber that projects rearwardly from the body.

Implementations of a capillary tube syringe are provided. In some implementations, a capillary tube syringe comprises an elongated hollow outer tube having a proximal end and a distal end and a needle extending from the first end of the outer tube outside the outer tube and extending inside the outer tube. In some implementations, an elongated hollow capillary tube having a proximal end and a distal end extend along the inside of the outer tube. In some implementations, a normally compressed spring is operatively connected to the needle. In some implementations, the spring is configured to expand when activated to retract the needle inside the elongated hollow tube. In some implementations, the capillary tube diameter is less than or equal to 0.865 inches.

A medical device configured as a blood collection tube holder, the device having a body with two spaced-apart, oppositely facing, coaxially aligned needles including a forwardly facing venipuncture needle and a rearwardly facing fluid discharge needle, the two needles being held by first and second needle holders separated by a compressible fluid seal defining part of a fluid path between the two needles and the two needle holders. The body also includes a discharge needle displacement member that is manually repositioned following removal of the last blood tube holder so that the discharge needle displacement member contacts the second needle holder and displaces the second needle holder and the fluid discharge needle laterally inside the body to initiate retraction of the venipuncture needle into a rearwardly projecting needle retraction chamber.

The invention is a bodily fluids sample collection device comprising a planar elastic elongated frame member and has frame sides concurrently angling inward to a cup securing region, thereby having an increasingly narrowing frame width to a semi-circular cup holding portion, adapted to securely receive a bodily fluids sample cup disposed in an upright position for receiving a bodily fluids sample from a patient, and flexibly adapted for easy placement and release of the bodily fluids sample cup. The toilet bowl or the toilet seat freely supports the device, and handles enables the patient to grasp the device without touching the toilet seat or the toilet bowl, and away from the sample cup of differing sizes. The device may have a collection handle, enabling the patient to grasp the device away from the bodily fluids sample cup.

A standalone safety device for a needle of a medical device A safety device for a needle of a medical device, the safety device including: a ring fixed with regard to the needle, a shield mounted on the ring by a pivot link, a protective cap covering at least partially the needle in an initial configuration, a translation locking unit adapted to prevent a translation movement of the protective cap, and a rotation locking unit adapted to prevent a rotation movement of the shield with regard to the ring. The translation locking unit is configured to be disengaged by the application of a predetermined translation force on the protective cap. The rotation locking unit is configured to be disengaged during a portion of the translation movement of the protective cap with regard to the shield.
