Catheter for recovery of dysphagia
The present invention provides a catheter for assisting recovery from dysphagia.
1. A method of manufacturing a catheter for assisting recovery from dysphagia, the method comprising:
providing a pre-formed storage container having one or more formations for receiving at least part of a catheter;
providing a catheter comprising a feeding tube, a sleeve for receiving the feeding tube and being movable longitudinally relative to the feeding tube and a retaining formation having a first part and a second part connected by a living hinge, attached to the sleeve for fixing the position of the sleeve relative to the feeding tube, the second part being movable relative to the first part between an open position whereby the sleeve can be moved longitudinally relative to the feeding tube and a closed position, whereby the feeding tube is clamped between the first part and the second part to positionally fix the sleeve relative to the feeding tube;
inserting the catheter into the storage container such that at least part of the catheter is received and deformed by the one or more formations of the storage container; and
exposing the storage container to pre-determined conditions of one or more of temperature, humidity, pressure, vacuum, gas or radiation for a pre-determined time to both sterilise and shape set the catheter, whereby upon completion of the application of those conditions, the at least part of the catheter maintains its deformed shape when removed from the storage container, wherein the storage container and sterilisation provide conditions to configure the deformed shape of the catheter, wherein the storage container used to confer the shape to the catheter is a final packaging for the catheter.
2. The method of manufacturing a catheter of claim 1 , wherein the at least a part of the catheter deformed by the one or more formations of the storage container is the feeding tube and/or the sleeve.
3. The method of manufacturing a catheter of claim 2 , wherein deformation occurs by breaking polymer bonds of a material of the feed tube and/or sleeve.
4. The method of manufacturing a catheter of claim 3 , wherein when the feeding tube and/or sleeve are removed from exposure to one or more of said conditions, the polymer bonds of the material reform such that at least a part of the feeding tube and/or sleeve naturally take the profile of a packaging of the storage container.
5. The method of manufacturing a catheter of claim 1 , where the predetermined conditions that facilitate deformation occur during a terminal sterilisation step of manufacturing.
6. The method of manufacturing according to claim 5 , wherein the terminal sterilisation step comprises ethyl oxide sterilisation.
7. A method of manufacturing a catheter for assisting recovery from dysphagia, the method comprising:
providing a pre-formed storage container having one or more formations for receiving at least part of a catheter;
providing a catheter comprising a feeding tube, a sleeve for receiving the feeding tube and being movable longitudinally relative to the feeding tube and a retaining formation having a first part and a second part connected by a living hinge, attached to the sleeve for fixing the position of the sleeve relative to the feeding tube, the second part being movable relative to the first part between an open position whereby the sleeve can be moved longitudinally relative to the feeding tube and a closed position, whereby the feeding tube is clamped between the first part and the second part to positionally fix the sleeve relative to the feeding tube;
inserting the catheter into the storage container such that at least part of the catheter is received and deformed by the one or more formations of the storage container; and
with the at least part of the catheter received and deformed by the one or more formations, exposing the storage container to pre-determined conditions of one or more of temperature, humidity, pressure, vacuum, gas or radiation for a pre-determined time to simultaneously sterilise and shape set the catheter, whereby upon completion of the application of those conditions, the at least part of the catheter maintains its deformed shape when removed from the storage container, wherein the storage container used to confer the shape to the catheter is a final packaging for the catheter.
