@JTwithJD Hi J.D., and Welcome to the JDRF TypeOneNation Forum! Only 46 years without a pump? Just about like me, I began with a pump in my 47th year, and now I’m happy using my fourth pump.
Keep in mind, that a pump will NOT, by itself “fix” your bouncing blood sugar - a pump is only as good as the data you feed into it. As the accountants are know to say GIGO - garbage in, garbage out. That said, the pump with continuous glucose monitoring system I’m currently using is almost fully automated - it is known as an iAIDs, an Integrated Automated Insulin Delivery system. It is the Tandem t-Slim x2 pump paired with a Dexcom G6 continuous monitor, and is controlled by the Control IQ [CIQ] algorithm. Three different physician prescriptions are needed for use of this system.
I suggest that tour tour the Tandem [tandemdiabetes.com] and the DexCom [dexcom.com] websites and learn for yourself what these devices might do for you. Both of these companies post really good videos demonstrating capabilities, there are also many user videos available on the web.
Supplies; yes in addition to the pump [the Tandem insulin infusion pump is actually a sophisticated, rather expensive computer], you will need infusion sets - the piece you stick into your body and change out at least every three days, and insulin cartridges which you fill and replace when you change infusion set. You can get insulin from your usual supplier; pumps require Rapid-Acting [not Fast-acting] Insulin formulation such as Humalog or Novolog.
Continuous Glucose Monitoring [CGM] system requires a Receiver /Reader and sensors that you implant in your body, and change out periodically. The DexCom G6 must be changed every ten days. I use my Tandem t-Slim pump as my primary CGM receiver.
Good luck with your search. This is a change that will need to be approved by your attending physician.
