A portal access device has a first member pivotally movable relative to a base. A groove is provided at the first member to be in alignment with a bore at the base, so that a cannula may freely extend through the bore, with a portion of the cannula being frictionally held along the groove of the first member. The first member may be rotatably connected to a second member, so that once the cannula is correctly inserted into a portal, the first member may be pivoted from its vertical position to its horizontal position to bend the cannula into a right angle cannula. The cannula is removed from the portal by pivoting the second member upwardly away from the base. In an alternate portal access device where there is only one arm member, the portal access device may be removed from the portal by being pulled vertically upwards.

A tracheostomy dilator moulded from a plastics material is formed with an S shape having a flexible, tapered patient end region for insertion to the trachea. A handle region at the opposite end has a substantially constant diameter along its length. A passage along the dilator receives a guide member, the tip of the patient end of the dilator making a stepless transition with the surface of the guide member.

By interposing an adapter between the endotracheal or tracheal tube inserted to a patient and the ventilation and suction systems that are connected to the endotracheal tube, a catheter could be inserted via an input port built into the adapter so as to enable a medical personnel to provide localized treatments in the lungs of a patient without having to disconnect either one of the systems connected to the endotracheal tube. The adapter is configured to have a securing mechanism that allows the medical personnel to secure the medication catheter in place. A one way valve fitted to the apertured arm that forms the input port of the adapter prevents any back flow of fluid from the input port. The catheter is manufactured with calibration markings, most likely equally spaced, and a radiopaque line along its length to enhance the maneuvering and the positioning thereof in the patient so that the distal tip of the catheter could be accurately positioned to the desired location of the patient's tracheal/bronchial tree. As a result, the localized treatment such as the injection of a medicament is accurately provided to the appropriate location where the need is the greatest.

A needle protective housing is fitted to the neck of a medicament container, for example a glass vial, that has a circumferential notch formed at a proximal portion of the neck. The needle protective device has a needle protective housing pivotally connected to a cup-shaped collar. The collar has a base that is formed by a plurality of coplanar extensions, that in turn form an aperture that allows the base to be press-fitted onto the neck of the vial. The extensions are each separated by a space, so that the extensions would give way when the collar is slidedly fitted along the length of the neck of the vial, until the extensions reach the notch at the proximal end of the neck of the vial where the extensions return to the original shape to thereby couple the collar to the vial. The circular wall upraised from the base of the collar is internally threaded for accepting the luer of a needle assembly, when the needle assembly is mated to the neck of the syringe. Once fully threaded into the collar, the interaction of the luer and the base of the collar effects a tightly gripped fit of the base about the neck of the collar. Once the housing is pivoted to cover a contaminated needle, a lock mechanism at the housing would fixedly retain the needle. Once retained, the contaminated needle will continue to be retained within the housing even in the unlikely event that the collar and needle protective housing are forcibly removed from the vial.
