Medical illustration, schematic drawing, graphic figure -- 2

We are writing a medical article about remote follow-up of patients with pacemakers and ICD's. We would like a simple schematic drawing that illustrates the communication circuit between: patient with pacemaker/ICD - transmitter- server - hospital computer and medical staff.

For reference/ information on how these remote monitoring systems are working it can be helpful to make a quick Google search on for example Medtronic "CareLink", Boston "Latitude", Abbott "Merlin.net" or Biotronik "Home Monitoring".
