Patent

CA 2585246

A needleless connector for adding medication to a parenteral fluid is provided. The needless connector comprises a connector (1) adapted to receive a syringe (5) and having a check valve to seal the port in place of a puncture pad. The check valve comprises a resilient disc (13) held in place and biased closed by the tensile stress of the check valve material. When a syringe or other apparatus having a male luer connector (14) is engaged with the connector and fluid pressure is applied to the check valve the resilient disc is deformed which allows the medication to flow through the connector into the tubing and thus to the patient.

L'invention concerne un connecteur sans aiguille qui permet d'ajouter un médicament à une solution parentérale. Ce connecteur sans aiguille comprend un connecteur conçu pour recevoir une seringue et comprenant un clapet de non-retour permettant de sceller l'orifice à la place d'un tampon à percer. Le clapet de non-retour comprend un obturateur souple maintenu et sollicité par la contrainte de traction du matériau du clapet de non-retour. Lorsqu'une seringue ou un autre appareil pourvu d'un connecteur Luer mâle est raccordé avec le connecteur et que la pression fluidique est appliquée au clapet de non-retour, l'obturateur souple est déformé, ce qui permet au médicament de s'écouler dans le tube puis dans le patient à travers le connecteur.
