What power supply voltages are supported by this device?

The device can accept voltages between 110 ~ 250V so can be used internationally.

When does the syringe need to calibrated?

Calibration is recommended before each dialysis treatment. If the message "syringe is out of position" is displayed by the device during dialysis then syringe needs to be calibrated.

What to do if the message "body tubing blockage" is displayed by the device when peritoneal fluid is being pumped out during dialysis?

If body tubing blockage occurs upon dialysis immediately after a surgical procedure, we recommend operating again right away to remove the tissue causing the blockage; if the blockage only appeared after one or two days, try adjusting the animal's posture or removing the syringe from the device to manually pump out any debris that has become attached to the dialysis catheter inside the abdomen.

Is there a warning if it is pumping air?

The water wheel alarm will switch off automatically when the flow rate is between 1 ~ 3. No alarm will therefore be triggered if air is pumped. Under normal conditions, no gases will be drawn through the body tubing unless the connection between the body tubing and dialysis catheter has worked loose.

Is there a risk of contamination if the same syringe is used for pumping out dialysate and peritoneal waste fluid?

The dialysate and the abdominal cavity are both sterile. The syringe has been sterilized as well. As long as the supplies are only used for one day as directed then cross-contamination via the syringe is unlikely. Waste fluid backwashing into the dialysis device is the only probably way of contaminating the dialysate.
If contamination is a concern, dialysate can be sampled from the injection cap of the body tubing for a bacteria culture to be cultivated.

When the peritoneal waste fluid is being pumped out by the device, can the animal's abdominal wall be damaged by too much suction?

The front end of the body tubing will be connected to dialysis catheter with a cross-shaped groove. Suction will therefore be distributed over four indentations at the front end of the grooves ensuring that the animal's abdominal wall does not suffer tissue damage from excessive suction. The device will not keep pumping if there is a blockage in the body tubing either.

If the animal needs to undergo an X-ray during dialysis, what to do with the tubing?

The device does not hold a battery charge. It will automatically shut off one minute after the power supply is disconnected. No power will be supplied to the motor then. If the animal needs to be moved over a longer distance, the dialysis procedure can be suspended and the body tubing disconnected. The dialysis catheter or extension tubing should then be securely capped and sealed. When dialysis can be resumed, simply connect the body tubing with the dialysis catheter following the standard sterilization procedure.

What if there still seems to fluid left in the abdominal cavity after the dialysate has been pumped out during the dialysis procedure?

If a small amount of dialysate remains in the abdominal cavity during dialysis no action is necessary; a small amount of fluid remaining inside the animal after dialysis will not have any ill effects either. If there is a significant amount of fluid left in the abdominal cavity after the dialysis, disconnect the body tubing and drain line from the device then allow the waste liquid to be drained by gravity from the animal's abdominal cavity.

If the settings had been changed from the factory defaults, what should I do if I want to return to the factory defaults but don't remember the original settings?

Go to the Setup page and select Restore Factory Defaults. All of the device settings will now be restored to the factory defaults. The device will now revert to the English interface. The language can be changed to Traditional Chinese in Setup.

If dialysis needs to be performed over-night, does someone need to stay at the hospital and keep watch over the animal overnight as well?

Peritoneal dialysis is usually only necessary during the first 24 hours of intensive care. In this case, simply set the parameters and have the dialysate ready. The vet/assistant will only need to be on duty in the clinic and does not have to stay next to the device at all times; the device will sound the alarm if there is a problem. Basic physiological monitoring, measuring of blood pressure and medication will still need to be performed. The animal's condition can be checked at the same time. Once the values come down after a few days, treatment will only need to be carried out during the daytime.

Once supplies have been sterilized how long can they be stored in a sealed state?

Recommended storage time is 3 years. There is risk of contamination beyond that time.

How long can supplies be used for after the seal is broken?

Supplies are for one-time use only. To reduce the risk of contamination and animal infection, please scan the barcode on the packaging before the start of the dialysis. The supplies can then be used for 24 hours after the barcode scan plus 30 minutes for preparation time. If the device is run continuously without any problems and the power is not turned off at any time, supplies can be used for up to 48 hours.

What if the body tubing is not long enough?

This problem can be overcome through the use of extension tubing. If one extension tube is not enough then use two. This will also help reduce the risk of contamination to the dialysis catheter.

If a bag of dialysate was not all used, can the remainder be used on a second animal?

Not recommended. Fresh dialysate should be used to avoid contamination.

While performing dialysis the machine stopped, an alarm sounded, and there was an error message. The message on the screen said: "Expect the water direction is push but now is stop" (Note: depending on the expected direction of flow, error message can also read, "Expect the water direction is pull but now is stop") What does this message mean, and what action should be taken?

This error occurs when the rate of flow measured by the waterwheel has either stopped or is slower than it should be. This is most commonly the result air infiltration into the system. If this error occurs you may see air bubbles collected in the area of the waterwheel. If the amount of air in the waterwheel appears to be small, check all the tubing connections to make sure they are secure and then try continuing the process. If there appears to be a significant amount of air in the system, or if the error occurs again after resuming the process, the dialysis should be terminated and the system re-primed. To terminate, first press and hold "pause" in response to the alarm, and then select "Terminate" on the next screen. If there is dialysate remaining in the patient that needs to be removed, press "Yes" when asked, "Do you want to flow out?" If not, press "No". Then press "Yes", when asked, "Do you want to lock the valves?" The system will then return to the main screen. Press "Start", then "Skip" when prompted to enter the barcode (unless you are changing the tubing to a fresh set). Then press "Yes" when asked, "Need to perform priming?", and proceed with the priming process. Be sure to also check the tubing connections to be sure there is no air infiltration.
