Abstract

"SERINGA DE AGULHA RETRáTIL". A presente seringa tem uma característica de prevenção à reutilização, na qual a haste de êmbolo (26) e uma proteção de agulha (38) são destruídas e a agulha (64) é retraída dentro da haste. Esta característica requer apenas um aumento de força ao longo da mesma linha de ação de acordo com o golpe de injeção. Isto permite uma injeção com uma das mãos, segura, crítica em algumas situações. A seringa também minimiza a quantidade de medicamento desperdiçado tendo em vista que a ponta de haste de êmbolo (28) ocupa o volume inteiro dentro do barril (20). A seringa de agulha retrátil utiliza ajustes Luer-Lok padrões e podem ser usados com uma variedade de agulhas padrões que têm cânula retrátil. Uma agulha de calibre grande pode ser utilizada para encher a seringa a partir de um frasco ou outro recipiente antes de fixar a agulha de segurança para injeção. Finalmente, o êmbolo pode ser completamente encapsulado pelo barril, impede a reutilização da seringa e possibilita um descarte fácil e seguro.
