    Abstract: Conjunto de cánula rompible (12) para una circuito de fluido que comprende: un alojamiento (26) con una pared (46) que define un agujero (28) que presenta un diámetro interno e incluye una zona acanalada (56) que sobresale de la pared (46) hacia el agujero, presentando la zona acanalada (56) un diámetro limitado menor que el diámetro interno de la pared (46), y un elemento de cánula (32) en el agujero (28) que comprende una base (34), una punta (38), una junta rompible (44) entre la punta (38) y la base (34), incluyendo la punta (38) una parte delantera (64) sin ningún saliente que se acople por fricción ni en la pared (46) ni en la zona acanalada (56), con lo cual ni la pared (46) ni la zona acanalada (56) limitan el movimiento de la parte delantera (64) a través del agujero (28) cuando la punta (38) se separa de la base (34) rompiéndola, incluyendo también la punta (38) una parte posterior (66) que incluye como mínimo un saliente (68) formado para acoplarse por fricción en la zona acanalada (56), con lo cual la zona acanalada (56) limita el movimiento de la parte posterior (66) a través del agujero (28) cuando se separa la punta (38) de la base (34) al romperla.

    Abstract: A breakable seal is located within a housing. The housing includes a ribbed region of restricted diameter protruding from the wall into the bore. A breakable juncture in the seal joins the tip of a cannula member to the base of the cannula member. The leading portion of the tip is free of any projection that frictionally engages either the wall or the ribbed region. Thus, neither the wall nor the ribbed region contacts or constrains movement of the leading portion in the bore when the tip is broken from the base. The trailing portion of the tip carries at least one projection constructed to frictionally engage the ribbed region. The ribbed region constrains movement of the trailing portion through the bore when the tip is broken from the base. By rocking the cannula tip, the juncture can be broken and the cannula tip advanced to a secure position in the housing.

    Abstract: A frangible seal for a fluid path including a frangible seal member secured within a tube defining the fluid path. The frangible seal member having a tubular seal member and a stem extending from the tubular seal member which, upon bending back and forth, breaks away from the seal member thereby to rupture the tubular seal in the fluid path. The tubular seal member and stem are integrally formed of a non-PVC material. The tubular seal member will bond to PVC tubing during steam heating thereof. The tubular seal member and stem are constructed to provide uniform non-reclosable rupturing. The stem includes vanes with spurs that frictionally engage the inner walls of the tube to maintain separation of the stem and ruptured tubular seal member.
