Abstract

"SERINGA RETRáTIL INVIOLáVEL". Uma seringa retrátil não-reutilizável, inviolável (10) tem um corpo externo oco inteiriço (12) com um corpo tubular (14) para um êmbolo deslizante, uma zona de transição (18) e uma parte de nariz (16) de menor diâmetro. Uma combinação de porta-agulha alongado (22) e mola (24) é instalada a partir da traseira do corpo externo, guiada para o interior da parte de nariz e retida por superfícies voltadas para dentro e para fora cooperantes orientadas na direção de retração na parte mais estreita da zona de transição onde o nariz se inicia. O êmbolo tem uma abertura com um batoque desalojado (42) para receber partes do mecanismo de retração (20). O batoque e a cabeça do porta-agulha são de diâmetro significativamente reduzido em relação à camada de fluido de injeção para resistir à ejeção prematuramente. Na concretização a cabeça do porta-agulha é circundada por um membro retentor separável que é deslizantemente removido pelo contato com a ponta do êmbolo após o batoque ser essencialmente ou completamente removido para evitar o acúmulo de força requerido para retração após a injeção."INVIOLABLE RETRACTABLE SYRINGE". A non-reusable, tamper-proof retractable syringe (10) has a one-piece hollow outer body (12) with a tubular body (14) for a sliding plunger, a transition zone (18) and a smaller diameter nose part (16) . A combination of elongated needle holder (22) and spring (24) is installed from the rear of the outer body, guided into the nose portion and retained by cooperating inward and outward facing surfaces oriented in the retracting direction on the nose. narrowest part of the transition zone where the nose begins. The piston has an opening with a dislodged bung (42) for receiving parts of the retracting mechanism (20). The bung and needle holder head are significantly reduced in diameter relative to the injection fluid layer to resist ejection prematurely. In the embodiment the needle holder head is surrounded by a detachable retaining member which is slidably removed by contact with the plunger tip after the tapping is essentially or completely removed to prevent the buildup of force required for retraction after injection.
