Abstract
A medical catheter that includes an elongate main tube, the tube having an outer wall that surrounds an internal passage, branch tubes having an outer wall connected to the outer wall of the main tube which extend outward from the main tube in different respective directions and have one or more apertures passing through their outer wall to their internal passage to permit fluid to pass through the branch tubes and into the main tube in use. The branch tubes are arranged to be able to move towards each other to permit location of the catheter within the bore of a needle or needle-like apparatus and which return to their original outwards state when removed.
Claims22
A medical catheter, comprising:
- an elongate main tube, the tube having an outer wall which surrounds an internal passage;
- first and second branch tubes, each having an outer wall connected to the outer wall of the main tube, which outer wall surrounds an internal passage which is in communication with that of the main tube, wherein the branch tubes extend outwards from the main tube in different respective directions and have one or more apertures passing through their outer wall to their internal passage to permit fluid to pass through the branch tubes and into the main tube in use, and wherein the branch tubes are arranged so as to be resiliently movable, generally towards each other, to permit location of the catheter within the bore of a needle or needle-like apparatus and which return to their original outwards state when removed.
A medical catheter comprising a main tube having first and second ends, and at least two, shorter, branch tubes which extend outwardly from at, or near, the first end of the main tube on opposite sides to form an approximate Y-shape, the branch tubes each having one or more apertures formed through their side wall so as to provide a fluid passage from the branch tube into the main tube, the branch tubes being connected to the main tube in a flexible and resilient manner such that they can be moved together and located within a needle or needle-like structure and which are biased so that they return to their original outwards position when removed therefrom.
An apparatus for locating a catheter in a medical procedure, the apparatus comprising:
- a barrel having a first end and a second end and a sidewall defining an interior chamber;
- a needle or needle-like member having first and second ends and a longitudinal passage extending between said ends, the first end of the needle being connected in use to the second end of the barrel, and the second end of the needle being a free-end, the longitudinal passage being arranged in use to house a catheter according to any preceding claim;
- a plunger locatable within the interior chamber of the barrel for reciprocal movement therein between a non-depressed position and a depressed position and connected to a plunger rod which passes through the barrel second end and part-way along the passage of the needle so as to cause ejection of only part of the catheter from the needle free-end as the plunger is moved towards the depressed position in use.
