Abstract

"SERINGA HIPODéRMICA COM UMA AGULHA SELETIVAMENTE RETRáTIL". Descreve-se uma seringa hipodérmica com uma agulha seletivamente retrátil, que inclui um cilindro alongado que define um receptor e uma alma oca. A seringa tem um êmbolo com uma cavidade alangada aberta para a extremidade proximal. O êmbolo é dimensionado para encaixar dentro da alma do cilindro, para proporcionar um movimento deslizante, a fim de definir uma câmara para receber e expelir fluidos. O diâmetro interno da cavidade no êmbolo é suficiente para acolher telescopicamente pelo menos uma parte da primeira parte do êmbolo. Uma segunda parte e a primeira parte são unidas em uma união, para formar um ressalto que estende-se para fora a partir da primeira parte, sendo o êmbolo desmanchável telescopicamente pelo movimento da segunda parte para dentro da cavidade, por uma força distal suficiente para romper de modo frangivel a união. A seringa inclui uma manga alongada dimensionada para encaixar sobre a primeira parte do êmbolo e estende-se a partir do ressalto. O êmbolo inclui um limitador para formar um selo à prova de vazamento de fluidos com o cilindro. A manga tem uma superficie cortante dentro do limitador. A seringa inclui uma luva com uma flange proximal e uma passagem dentro do receptor. A seringa tem uma agulha com uma extremidade distal pontiaguda na passagem da luva, estendendo-se para fora. Quando uma força distal é aplicada para desmanchar o êmbolo, a superfície cortante da manga corta o limitador e a flange da luva libera-a do receptor para retrair a agulha.
