Abstract
The present invention relates to a device (1) for irrigation of externally debouching, natural or artificial body canals of animals or human beings. The device comprises a catheter (2), and optionally a container (3) designed for containing irrigation medium (4) and a tube member (5) connecting the catheter (2) with the container (3). The catheter is provided with a fixation member (6) for fixation of the catheter inside the body canal and for providing a liquid tight seal between the catheter (2) and the body canal, which fixation member (6) automatically fixates and seals around the catheter (2) when placed in the body canal. The invention further relates to a method of producing the device. Finally, the invention relates to the use of the device (1) for performing irrigation on a person.
Claims33
A device for irrigation of externally debouching, natural or artificial body canals of animals or human beings comprising:
- a catheter provided on an outer surface thereof with an annular fixation member, said fixation member being made of compressible material in the form of a resilient externally compressed plug-like body of moulded material that is self-expandable, said fixation member being externally compressed against a catheter, without fluid communication therebetween, by a covering film material that dissolves upon exposure to humidity, said fixation member self-expanding upon dissolution of said covering film material such that both expansion and compression of said fixation member are effected without fluid communication between said catheter and said fixation member.
A method of producing a device for irrigation of externally debouching, natural or artificial body canals of animals or human beings, comprising the steps of:
- providing a catheter, molding a fixation member made of a compressible material around the catheter in a selected position such that there is no fluid communication between said fixation member and said catheter, externally compressing the fixation member, and covering the compressed fixation member with a wrapping made of a film material which dissolves upon exposure to humidity, said fixation member being self-expandable with or without moisture upon removal of said wrapping.
A method for performing irrigation of externally debouching, natural or artificial body canals of a person, using a device having a catheter provided with an annular fixation member made of a resilient compressible molded material that is self-expandable, comprising the steps of:
- inserting a catheter with a fixation member compressed by a covering film material which dissolves upon exposure to humidity in the rectum of said person;
- allowing said film material to dissolve and thereby release said fixation member to expand and thereby provide a tight seal between the catheter and the rectum, said fixation member when expanded having a bowl-shaped upper surface;
- lifting a container connected to the catheter via a tube member above a level of the rectum and emptying a content of the container through the tube member and the catheter and into at least rectum, colon sigmoideum and colon descendens;
- waiting for a span of time between about 3 and 30 minutes and finally removing the catheter together with the fixation member from the rectum.
A device for irrigation of externally debouching, natural or artificial body canals of animals or human beings comprising:
- a catheter provided on an outer surface thereof with an annular fixation member, said fixation member being made of compressible material in the form of a resilient externally compressed plug-like body of molded material that is self-expandable, said fixation member being compressed by a covering film material that dissolves upon exposure to humidity, said fixation member self-expanding upon dissolution of said covering film material, said catheter including members extending from the surface of the catheter and forming a mechanical lock for the fixation member.
A device for irrigation of externally debouching, natural or artificial body canals of animals or human beings comprising:
- a catheter provided on an outer surface thereof with an annular fixation member, said fixation member being made of compressible material in the form of a resilient compressed plug-like body made of a relatively soft polyurethane foam that is self-expandable, said fixation member being compressed by a covering film material that dissolves upon exposure to humidity, said fixation member self-expanding upon dissolution of said covering film material.
A device for irrigation of externally debouching, natural or artificial body canals of animals or human beings comprising:
- a catheter provided on an outer surface thereof with an annular fixation member, said fixation member being made of compressible material in the form of a resilient compressed plug-like body of molded material that is self-expandable, said fixation member being compressed by a covering film material that dissolves upon exposure to humidity, said fixation member self-expanding upon dissolution of said covering film material and further including an extraction member made of a soft and flexible material with a knitted structure for withdrawal of the device.
A device for irrigation of externally debouching, natural or artificial body canals of animals or human beings comprising:
- a catheter provided on an outer surface thereof with an annular fixation member, said fixation member being made of compressible material in the form of a resilient compressed plug-like body of molded material that is self-expandable, said fixation member being compressed by a covering film material that dissolves upon exposure to humidity, said fixation member self-expanding upon dissolution of said covering film material and further including an extraction member made of a soft and flexible material, including at least one of plastic and fabric, for withdrawal of the device.
