Abstract

"SERINGA COM AGULHA RETRáTIL". Trata-se de uma seringa retrátil que inclui um cilindro dotado de uma câmara, uma extremidade proximal aberta e uma extremidade distal aberta. Um êmbolo é de forma deslizável posicionado em engate hermético a fluido com uma superfície interna do cilindro. O êmbolo é dotado de uma cavidade alongada em sua extremidade distal e um elemento de cobertura que sela a cavidade. O conjunto de agulha na extremidade distal do cilindro inclui uma cânula de agulha dotada de um cubo interno dotado de uma extremidade proximal aberta e uma extremidade distal conectada à cânula de agulha de modo que a luz da cânula está em comunicação fluida com a câmara. Uma borda no cubo interno é conectada à extremidade proximal do cubo externo de modo que a cânula da agulha projeta-se distalmente para fora a partir da extremidade distal do cubo externo. Uma mola é contida entre o cubo interno e o cubo externo. Um elemento de liberação circular é conectado de forma móvel à extremidade proximal da borda. O elemento de liberação é dotado de uma extremidade distal e uma extremidade proximal afiada e projeta-se para dentro da câmara, onde o movimento distal do êmbolo irá fazer com que a extremidade proximal afiada corte através do elemento de cobertura e a extremidade distal do elemento de liberação desassocia uma porção externa a partir da borda a partir da porção interna da borda e permite que a mola se expanda e mova a cânula de agulha para dentro da cavidade.
