Hello Maryriceot.
I have only had the battery operated shower for a week or so but it seems like just what I need. There are loads of different ones on the market for camping but I bought this one because it was 'upgraded' in terms of having the on/off switch outside the water. I bought mine from Amazon and it's described as:- Portable Camping Shower 2017 Upgraded, Acetek USB Rechargeable Handheld Shower Kit with Detachable 2200mAh Battery Pack, 200cm Hose, Shower head and Water Pump for Outdoor, Garden Plant Watering, Camping, Car & Pet Cleaning by Acetek.
The thing needed adapting for use as an irrigator so I'll share what alterations were needed.
1) The hose was cut off and connected to the hose supplied with a coloplast irrigator system that has the regulator switch. This makes it easier to control the flow, rather than just having an on-off situation.
2) I had already adapted the end so that I did not use a cone, but used the tip of an anal catheta, which is ideal for irrigation because that's what it was designed for. The tip can be cut off the catheta and it fits neatly onto the coloplast tubing.
3) However, before doing that, I cut a plastic showergel container to shape and drilled a suitable sized hole so that it could be fitted onto the tube to act as a splashback shield. It's surprising how effective and essential this little device is and it's much better than using the cone. (you can see a picture of this on my photo profile when it was attached to the pressurised garden sptrayer that I've been using for years.)
4) The water container I plumped for was a Lock&Lock 3.4 litre cereal dispenser because it held enough water and was then right shape for putting in my handluggage and storing the shower plus other stuff. It has the litres marked on the side- which I enhanced by marking wth a permanent marker becasue it would have been difficult to read when the container was on the floor
5) Before throwing the coloplast irrigator bag away, I salvaged the temperature guage and stuck it onto the side of the water container with double sided tape - it works very efficiently to indicate the temperature of the water inside and thus, helps to avoid water being too hot or too cold.
If I get time I will take a picture of the new device and post it so that you can get a better idea of what I am talking about. Don't be put off by the verbal description of what needs altering becasue it is all very simple really and the connectors are the same as the ones used in the Coloplast irrigator so your don't need to buy anything special. I will photgraph the anal catheta so that you know what it looks like in its entirety. However, I do believe that this is a luxury and the process could be undertaken with just the coloplast tube as long as it is smoothed off so that there are no rough edges. I got a supply of them from the surgeons who helped me when I was faecally incontinent but Im sure they would be stiull available through medical suppliers.
I hope this is a reasonable enough description to give you an idea of what you can do to rig up a battery operated irrigator ( total cost was about £30 )
Best wishes
