Problems solved by technology

This lack of control over spontaneous bowel function typically results in fecal incontinence or recalcitrant constipation because the patient's ability to sense the presence of feces in the terminal portion of the colon and rectum and to feel the stimulus to void has been significantly reduced
Patients who have undergone ostomy surgery (where a cannulated stoma is constructed) may suffer from similar difficulties

Embodiment Construction

[0085] figure 1 An embodiment of a system for anal and / or stoma irrigation is shown. The system includes a cannula 100 sized and configured for insertion into a user's rectum or stoma. A pump 101 is provided in a reservoir 102 for delivering irrigation fluid contained therein to the cannula 100 and to an expandable retaining element 104 in the form of a balloon which A positioning element secures the cannula in the user's rectum or stoma. Pump 101 is positioned within housing 200 .

[0086] Cannula 100 is typically a disposable component. For this purpose, a coupling device 160 is positioned between the cannula 100 and the tubing portion 121 . The coupling device 160 allows the cannula 100 to be decoupled from the tubing portion 121 and replaced as required. The coupling means 160 may take the form of a bayonet coupling, a push coupling or a screw coupling.

[0087] The first tubing portion 119 extends between the pump 101 and the control unit 103 , while the second tubi...

Abstract

A system for anal and / or stomal irrigation comprises a reservoir (102) for an irrigating liquid, a catheter (100) comprising a catheter tip for insertion into the rectum or stoma of a user and for expelling of the irrigating liquid from the catheter tip, and a tubing system (121) providing a conduit for the irrigating liquid between the reservoir and the catheter tip. A pump (101) is provided to pump the irrigating liquid from the reservoir to the catheter tip, and a control system (103) controls a flow condition, such as the amount of liquid expelled at the catheter tip. A sensor (153) determines a measure of pressure in at least one first predetermined position in the tubing system and / or the catheter during operation of the pump, on the basis of which the flow condition is estimated. The control system is configured to control the pumping operation of the pump in response to the measure of pressure.

Description

technical field [0001] Systems and methods for anal and / or stoma irrigation are provided, the system comprising: a reservoir for irrigation liquid; and a cannula comprising a cannula tip for insertion into a user in the rectum and / or stoma. In particular, a pump and tubing system for controlling the supply of irrigation fluid to the cannula tip and a control system for controlling the operation of the pump are provided. Background technique [0002] Patients with certain disabilities (eg, spinal cord injury, multiple sclerosis, or spina bifida) often have limited or no control over spontaneous bowel function. This lack of control over spontaneous bowel function typically results in fecal incontinence or recalcitrant constipation, as the patient's ability to sense the presence of feces in the terminal portion of the colon and rectum and to feel the stimulus to void has been significantly reduced. Patients who have undergone ostomy surgery (in which a cannulated stoma is cre...
