A closed collection system designed for hospitalised dogs suffering from severe, watery diarrhoea.

The system helps prevent extensive contamination of hospital kennels and protects staff working in the kennel area. It also allows the volume of fluid lost through diarrhoea to be monitored.

The system consists of a soft silicone rectal catheter featuring an inflatable retention balloon, an inflation port and a flushing port. The catheters are available in three sizes:

• 20 Fr – for small dogs
• 24 Fr – for medium-sized dogs
• 28 Fr – for large dogs

The collection bag is connected via a collection line fitted with a sampling port and a C-clamp. The bag itself features a non-return valve, a hanging hook and a printed volume scale for monitoring the collected output.

Directions for Use

Before inserting the rectal catheter, test-inflate the balloon. Note the volume of air or saline required to achieve approximately the same diameter as the dog’s normal stool.

Position the catheter so that the balloon sits anterior to the pelvic canal.

Air is generally recommended for balloon inflation, as it is more compressible than saline and may therefore reduce the likelihood of triggering straining.

Important: When air is used for inflation, the balloon must be checked every 3–4 hours. To do so, hold the catheter securely in position, deflate the balloon completely and then reinflate it with the same volume of air used during initial placement.

If the catheter becomes blocked, patency may be restored by gently flushing it with body-temperature saline through the flushing port.

To facilitate drainage, position the collection bag below the level of the dog.
