Prevención de exposición a la sangre en dispositivos de acceso vascular

Un aparato para impedir la contaminación con sangre con la retirada de una aguja hipodérmica que comprende: una aguja (40) que tiene una punta (42) y un protector (48) configurado para atrapar por lo menos parcialmente la punta de aguja con la retirada de la aguja; un material (56) que estabiliza la sangre dispuesto de tal manera que con la retirada de la aguja el material que estabiliza la sangre se dispone asociado operativamente con la punta de aguja de tal manera que se impide que la sangre que contacta con el material que estabiliza la sangre se escape del aparato, caracterizado porque el protector (48) incorpora un sujetador de seguridad (64) adaptado para cerrarse alrededor de la punta de aguja y para proteger el labio de aguja antes de que la aguja sea retirada completamente y el material (56) que estabiliza la sangre se dispone en una superficie exterior del sujetador de seguridad. An apparatus for preventing blood exposure or contamination upon withdrawal of a hypodermic needle is provided. The apparatus may include a needle having a tip and a shield configured to at least partially entrap the needle tip upon withdrawal of the needle. The apparatus may further include a blood stabilizing material disposed such that upon withdrawal of the needle the blood stabilizing material is disposed in operative association with the needle tip such that blood carried by the needle is prevented from escaping the apparatus. In some exemplary implementations, the blood stabilizing material may be disposed on one or more surfaces of the shield. The shield of the hypodermic needle may include protective device and/or a housing for shielding the needle tip upon withdrawal. The housing may be adapted to at least partially cover the needle tip upon withdrawal of the needle. In some implementations, the housing may be adapted to allow the protective device to shield the needle before the needle is completely withdrawn.
