FIELD OF THE INVENTION

The present disclosure relates generally to body cavity irrigation devices, methods and systems and, in particular, to a body cavity irrigation system controller.

BACKGROUND

Transanal irrigation (TAI) is a process used by individuals who have bowel management issues, such as incontinence, constipation or other neurogenic bowel dysfunction (NBD). Alternatively, TAI may be used for regular bowel evacuations by individuals who are incapacitated due to illness or other medical conditions or injuries (such as spinal cord injury) and thus lack the mobility to access a toilet. During TAI, water or other lavage liquid is introduced into the rectum and colon through a device positioned through the anus so that feces are flushed and evacuated. This creates pseudo-continence for the patient/user. Furthermore, individuals that are bedridden may develop fecal impaction. Such bowel obstructions may be removed via TAI.

Systems for performing TAI currently on the market allow the user to introduce water into the bowel through a rectal catheter while the user sits on a toilet or a commode/shower chair or lies in a bed. The user introduces an amount of water or other liquid into the bowel (typically 500-700 mL) in order to flush out stool located in the bowel passage. The user typically introduces the water, waits for a period of time and then allows gravity to flush the water and stool out of the body. The rectal catheter may have an inflatable/deflatable balloon to assist in retention of the catheter during water introduction. The balloon is typically inflated by a fluid such as air or water.

For TAI users, independence, dexterity, and ease of use are important needs that must be addressed by a TAI system or method.

SUMMARY

There are several aspects of the present subject matter which may be embodied separately or together in the devices and systems described and claimed below. These aspects may be employed alone or in combination with other aspects of the subject matter described herein, and the description of these aspects together is not intended to preclude the use of these aspects separately or the claiming of such aspects separately or in different combinations as set forth in the claims appended hereto.

In one aspect, a controller for a body cavity irrigation system, including a reservoir containing an irrigation liquid and a catheter, features a housing with a dial attached to the housing and movable between positions corresponding to stages of a body cavity irrigation procedure. The controller is in communication with an electromechanical pump and at least one electromechanical valve that are in fluid communication with the reservoir and the catheter so that the electromechanical pump and at least one electromechanical valve are configured to perform a stage of the body cavity irrigation procedure corresponding to a selected dial position.

In another aspect, a system for performing a body cavity irrigation procedure includes a reservoir configured to contain an irrigation liquid and a catheter including a curved shaft and a curved hub configured to be gripped by a user. The system also includes a controller that features a housing with a dial attached to the housing and movable between positions corresponding to stages of the body cavity irrigation procedure. The controller is in communication with an electromechanical pump and at least one electromechanical valve that are in fluid communication with the reservoir and the catheter so that the electromechanical pump and at least one electromechanical valve are configured to perform a stage of the body cavity irrigation procedure corresponding to a selected dial position.
