The present disclosure relates generally to body cavity irrigation devices, methods and systems and, in particular, to a transanal irrigation device that includes an extended handle that is usable by patients possessing a wide range of dexterity levels and systems that use such a device.
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 lays 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.
For TAI users, independence, dexterity, and ease of use are important needs that must be addressed by a TAI system or method.
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 device for performing transanal irrigation includes an elongated neck having a proximal end and a flushing liquid channel passing therethrough. The flushing liquid channel is adapted to communicate with a source of flushing liquid. An insert is positioned on the proximal end of the neck and is adapted to be inserted into a body cavity of a user. The insert has a flushing liquid opening that is in fluid communication with the flushing liquid channel of the neck. A control housing is connected to the neck. A pump is positioned within the control housing and is configured so that when the pump is activated, pressurized flushing liquid is able to flow through the flushing liquid channel and exit through the flushing liquid opening of the insert. A pair of support arms are attached to the neck and configured to rest on a sitting user's legs with the insert positioned below a body cavity of the user.
In another aspect, a system for performing transanal irrigation includes a liquid pressurizing device configured to contain and pressurize a supply of flushing liquid. The system also includes a transanal irrigation device having an elongated neck having a proximal end and a flushing liquid channel passing therethrough. The flushing liquid channel is in fluid communication with the liquid pressurizing device. An insert is positioned on the proximal end of the neck and is adapted to be inserted into a body cavity of a user. The insert also has a flushing liquid opening that is in fluid communication with the flushing liquid channel of the neck. A control housing is connected to the neck. A pump is positioned within the control housing and configured so that when the pump is activated, pressurized flushing liquid from the liquid pressurizing device flows through the flushing liquid channel and exits through the flushing liquid opening of the insert.
In yet another aspect, a device for performing transanal irrigation includes an elongated neck having a proximal end and a flushing liquid channel passing therethrough. The flushing liquid channel is adapted to communicate with a source of flushing liquid. An insert is positioned on the proximal end of the neck and has a core having a sidewall and a tip. The tip includes a flushing liquid opening that is in fluid communication with the flushing liquid channel of the neck. The insert also includes a flexible body surrounding an exterior surface of the sidewall in a spaced fashion so that an annular chamber is defined. The annular chamber is adapted to contain a lubricant and the flexible body includes a pore. A control housing is connected to the neck of the device. A pump is positioned within the control housing and is configured so that when the pump is activated, pressurized flushing liquid is able to flow through the flushing liquid channel and exit through the flushing liquid opening of the insert.
An embodiment of a transanal irrigation (TAI) system is indicated in general at 10 in
While the invention is described below in terms of use as a transanal irrigation device and system, it is to be understood that the invention could be used to irrigate other body cavities of a user including, but not limited to, stomas and body cavities accessible by stomas.
As illustrated in
An intermediate portion 42 is attached to the proximal end of the control housing 22, while an elongated neck portion 44 is attached to the proximal end of the intermediate portion 42. As illustrated in
As illustrated in
Support arm 64 is pivotally mounted to the intermediate portion 42 in a similar fashion and features a longitudinal axis 66. As indicated by arrow 70 of
A squeeze bulb 72 is mounted on a fitting 74. As illustrated in
With reference to
As shown in
Alternative heads may be positioned on the insert mount 82 in an interchangeable fashion. For example, a flushable pre-check head, which may or may not be cone-shaped, may be used.
As noted previously, with reference to
In operation, the flushing liquid within the liquid pressurizing device 14 is pressurized. The insert cone 90 is positioned on the proximal end of the device 12, as illustrated in
The user next moves the handle (control housing 22) downwards so that the proximal end of the neck portion 44, and thus the insert cone 90, rises towards the anus 120 (
Once the insert cone 90 is inserted into the anus and rectum, the user may initiate flow of the flushing liquid through the flushing liquid channel 46 (
After a period of time, the user pulls up on the handle 22 so that the insert cone 90 is removed from the user's rectum and anus, and the flushing liquid and fecal matter drain by gravity into the toilet.
If the user finds that the pump 26 is too powerful and/or is more comfortable using a manual pumping mechanism, the squeeze bulb 72 (
The user then repetitively squeezes and releases the squeeze bulb 72. Due to the check valves 78a and 78b (
The user may also wish to use the squeeze bulb 72 to add additional flushing liquid to the rectum after the pump 26 is used.
While the preferred embodiments of the disclosure have been shown and described, it will be apparent to those skilled in the art that changes and modifications may be made therein without departing from the spirit of the disclosure, the scope of which is defined by the following claims.
The present application is the U.S. National Stage Application of PCT Application No. PCT/US2017/065266, filed Dec. 8, 2017, which claims the benefit of and priority to U.S. Provisional Patent Application No. 62/434,143, filed Dec. 14, 2016, the contents of which are hereby incorporated by reference.
