Abstract

"seringa hipodérmica com agulha seletivamente retrátil". trata-se de uma seringa hipodérmica com uma agulha seletivamente retrátil que inclui um cilindro alongado que tem uma extremidade proximal aberta, uma extremidade distal aberta e um orifício oco. a seringa inclui um êmbolo alongado que inclui um alojamento externo oco que tem uma extremidade proximal aberta e uma extremidade distal aberta. o êmbolo tem uma camisa interna oca que define uma cavidade nela. o êmbolo tem elementos de engate liberáveis que impedem o movimento axial relativo entre o alojamento externo e a camisa interna, sendo que os elementos permitem o movimento axial relativo quando liberados e um tampão distal. existe um cortador aberto montado em uma extremidade proximal da camisa interna para cortar através do tampão para expor a cavidade na camisa interna quando os elementos de engate são liberados e força axial distal suficiente é aplicada ao êmbolo. a seringa tem um alojamento de cubo com uma extremidade proximal aberta que tem um ressalto que se projeta para dentro, um cubo com um flange proximal e uma haste axial, dimensionada para encaixar dentro do alojamento do cubo. existe uma mola disposta em torno da haste entre o flange e o ressalto. a seringa tem uma agulha com uma ponta afiada que se estende para fora. a agulha se retrai para dentro da cavidade no êmbolo quando força distal suficiente é aplicada ao êmbolo para liberar os elementos de engate. a liberação permite o movimento da camisa interna com relação ao alojamento externo tal que o cortador corte através do tampão e flange e a mola impila o movimento da agulha para dentro da cavidade.
