Abstract

"SERINGA HIPODéRMICA COM AGULHA SELETIVAMENTE RETRáTIL". Uma seringa hipodérmica com uma agulha seletivamente retrátil inclui um barril alongado tendo uma extremidade proximal aberta e uma extremidade distal que define um receptor com um ombro que se projeta para dentro. A seringa tem um êmbolo alongado oco com uma extremidade proximal aberta e uma extremidade distal fechada. Existe um tampão alongado que se estende no sentido distal para dentro do êmbolo oco a partir da extremidade proximal aberta, formando uma cavidade encerrada dentro do êmbolo. A seringa tem um cubo alongado tendo uma passagem através do mesmo, uma haste que se estende no sentido distal, e um flange proximal com um engate de modo a engatar o dito barril. A seringa tem uma agulha alongada com uma passagem de fluido através da mesma, uma extremidade distal afiada e uma extremidade proximal. A agulha é montada na passagem, de modo que a extremidade distal afiada se projete. A seringa tem uma mola alongada disposta sobre a haste do cubo que é comprimido entre o flange e o ombro que se projeta para dentro do receptor a fim de prover uma polarização. Há uma luva oca dimensionada de modo a se encaixar dentro do receptor sobre a mola alongada com uma extremidade afiada proximal disposta na ranhura do flange. Quando um usuário aplica uma força suficiente, o cubo se movimenta suficientemente no sentido distal no receptor para que a borda de corte da luva corte o flange e a extremidade distal fechada do êmbolo a fim de expor a cavidade para a retirada da agulha para dentro da seringa.
