Patent

CA 2141448

A transdermal injection appliance has a pad (16) impregnated with a disinfectant solution such as alcohol, a body (10) with adhesive for holding the pad against the skin of a patient, and a sleeve (20) with a guide passage (22) through the body for guiding an injection needle (32). A membrane (24) puncturable by the needle is attached to the sleeve to close the passage (22), the membrane being self-sealing so that an opening through the membrane formed by the needle is closed as soon as the needle is extracted, thereby wiping a majority of blood from the needle and preventing the escape of blood. The tubular sleeve can have an outer end with a coupling (26) for connection to a retractable needle injection assembly. A method of using the appliance with the retractable needle assembly to administer medication without exposing the health care giver to accidental contact with the needle is also disclosed.

Appareil d'injection transdermique possédant un tampon (16) imprégné d'une solution désinfectante telle qu'un alcool, un corps (10) pourvu d'une colle de maintien du tampon contre la peau du malade, et un tube (20) comportant un passage (22) traversant le corps de l'appareil et servant à guider une aiguille d'injection (32). Une membrane (24) susceptible d'être percée par l'aiguille est fixée au tube de manière qu'elle obture le passage (22), cette membrane étant autoscellable afin que l'ouverture formée dans la membrane par l'aiguille se referme aussitôt que l'on retire l'aiguille, et de manière que ladite membrane essuie la plus grande partie du sang présent sur l'aiguille tout en empêchant le sang de s'échapper. L'extrémité extérieure du tube peut comporter un raccord (26) assurant le raccordement à un ensemble d'injection à aiguille escamotable. On a également prévu un procédé de mise en oeuvre de cet appareil conjointement avec l'ensemble à aiguille escamotable dans le but d'administrer des médicaments sans risque de contact accidentel entre l'aiguille et la personne administrant la piqûre.
