Aiguille perforante (1) en matière plastique comprenant au moins un canal de passage de fluide (2a). L'aiguille perforante (1) comporte un tronçon distal (3a) à section transversale ayant une forme qui comprend au moins un angle saillant, de telle sorte que ladite aiguille perforante (1) comporte au moins une arête longitudinale extérieure (6) s'étendant le long de son tronçon distal (3a) et présentant un angle de dépouille (α).

A syringe device includes a syringe barrel and piston having a fluid passageway extending from a vial port. Another syringe device includes a syringe barrel, a piston sleeve and an insert. A channel extends along a side of the insert. A valve controls fluid communication between the channel and the syringe barrel. Another syringe device has a syringe barrel, a piston sleeve and an insert. A valve controls fluid communication between a compartment within the insert and the syringe barrel. A method of preparing a medication includes providing a component within a syringe barrel and another component within a compartment of a piston insert. A seal is over-molded onto a tip of the insert and an end of a piston sleeve. The sleeve is rotated relative to the insert to establish fluid communication between the compartment and the barrel chamber.

A drug storage and delivery device (1) comprising a reservoir (2) containing a liquid, a vial (3) containing a dry drug, such as a lyophilized drug, means (6) for forcing the liquid from the reservoir (2) to the vial (3), via an established fluid connection, and locking means adapted to prevent the means (6) for establishing a fluid connection from re-establishing a previously disconnected fluid connection between the reservoir and the vial. Thereby the dry drug is reconstituted, and the forcing means (6) may subsequently be used for forcing reconstituted drug out of the device (1). The reservoir (2), the vial (3), the fluid connection and the forcing means (6) may form an at least substantially integral unit. This is an advantage because the number of steps needed to be performed by the user is reduced, the risk of contamination is reduced, the risk of incorrect reconstitution and dosage is reduced, and the device is easy to operate, e.g. using just one hand.
摘要:
Spritzen-Adapter mit - auf jeder Seite - zwei versetzten, ineinander übergehende Bohrungen mit dem Zweck auch nicht baugleiche Spritzen beim Verbinden zu führen und zu fixieren. In der Schnittmenge der ineinander übergehenden Bohrungen ist der Fließkanal mit kleinerem Durchmesser positioniert. Die dünnere Bohrung des Fließkanals nimmt die Koni der Spritzen auf. Die Wände der größeren Bohrungen fixieren und stabilisieren die Spritzenzylinder während des Mischvorganges und verhindern das Durchbrechen oder Abbrechen. Die Wände der Führungsbohrungen sollen tnindest bis zur 1-ml Markierung der Spritzen reichen. Mit zunehmender Wandhöhe steigt die Stabilität des Systems.

Adapters for utilizing a syringe or pen injector with a subcutaneous injection port to deliver a therapeutic substance through the injection port and methods of using the adapters are provided. A syringe adapter has a body having a first end and a second end. The first end of the body is configured to receive and engage the end of a syringe so that the cannula of the syringe is held at a fixed position with the respect to the adapter. The second end of the adapter configured to mate with a mating portion of the injection port. When the second end of the adapter engages the mating portion of the injection port, the adapter assures that the cannula of the syringe is properly aligned with the subcutaneous injection port and assures that the cannula penetrates the injection port to the proper depth. Adapters for use with pen style delivery systems are also disclosed. Additionally, an adapter to facilitate loading a syringe with a therapeutic substance from a vial is disclosed.
摘要:
The invention provides a system for preparing an autologous solid-fibrin web suitable for regenerating tissue in a living organism. The system includes a sealed primary container containing a separation medium and a low-density high-viscosity liquid. The separation medium is capable of separating red blood cells from plasma when the container contains blood and is centrifuged, and the primary container has a first pressure. The system further includes a sealed secondary container containing a calcium-coagulation activator. The secondary container has a second pressure that is less than the first pressure. The system also comprises a transfer device including a cannula having a first end and a second end. The first and second ends are capable of puncturing the sealed primary and secondary containers in order to provide fluid communication between the first and second containers. The low-density high-viscosity liquid of the primary container is capable of blocking flow through the cannula upon entering therein.
