Thank you, Jesse, for more valuable information! I did not know that Medicare will pay for 30 syringes per month. I too have Medicare SSDI. I use BD 60ml catheter tip syringes and have tried a variety of keep clean methods, none of which seem to extend the life of the syringe. With 30 per month there should not be a problem. I do use the same syringe for my crushed meds and formula, and that might cause the short life problem. I have heard positives about the mic-key and will check with my doctor when it's time to change my tube.
