Abstract

Métodos para formar una costilla en una cánula para que coopere con una cubierta de seguridad que inmoviliza de manera segura y confiable la punta de una cánula en una cámara interior dentro de la cubierta de seguridad. la cubierta comprende un cuerpo alargado que tiene la cámara interior y un agujero pasante axial, que se extiende a todo lo largo del cuerpo, a través de la cámara interior, y a través del cual es recibida deslizablemente la cánula. Están dispuestos elementos desplazadores dentro de la cámara para recibir la cánula a través de él, y que se desplaza cuando se retrae la punta de la cánula, preveniendo de esa manera el avance subsecuente de la punta de la cánula. La cánula incluye una costilla engrosada, adyacente a la punta, y la cubierta de seguridad debe incluir, correspondientemente, una seccion anular en su porcion trasera. El agujero que se extiende a través de la porcion trasera tiene un diámetro que es menor que la costilla engrosada de la cánula, de manera que no se pueda retraer la punta de la cánula de la cubierta de seguridad. Está formada la costilla mediante un método térmico en el cual se calienta un manguito para dilatar su diámetro interior para permitir que se deslice el manguito sobre la cánula. Luego se enfría el manguito a la temperatura ambiente, de manera que el diámetro interior se contraiga para unir el manguito a la cánula. En otro método se coloca un manguito sobre la cánula y se riza en la ubicacion deseada.
