         36 . A system for delivering a fluid to a patient, comprising:
 a delivery device including,
 a reservoir storing the fluid to be infused, 
 a fluidic pathway in fluidic communication with the reservoir, 
 a pumping device configured to move the fluid from the reservoir to a body of the patient, and 
 a sensor configured to monitor at least one parameter associated with the operation of the system; 
   a processor;   an infusion set in fluidic communication with the fluidic pathway and configured to infuse the fluid into the body of the patient; and   an indication device configured to provide information to the patient,   wherein the processor is configured to,   receive the signal from the sensor,   determine a status of the infusion set based on the signal of the sensor, and   inform the patient via the indication device about a status of the infusion set.   
     
     
         37 . The system according to the  claim 36 , wherein the processor configured to prompt a change of the infusion set. 
     
     
         38 . The system according to the  claim 36 , wherein the infusion set is removably coupled to the delivery device. 
     
     
         39 . The system according to the  claim 36 , wherein the indication device is configured to display information corresponding to a quality of the infusion set, and/or a characteristic of the infusion site, and/or a fluidic resistance at the infusion site, and/or a remaining time before a change of the infusion set. 
     
     
         40 . The system according to the  claim 36 , wherein the indication device is configured to display a color index depending on the status of the infusion set. 
     
     
         41 . The system according to the  claim 36 , wherein the indication device includes a screen. 
     
     
         42 . The system according to the  claim 41 , wherein the screen is configured to display a home page that is configured to display a status of the infusion set. 
     
     
         43 . The system according to the  claim 36 , wherein the processor is configured to suggest a behavior to the patient via the indication device. 
     
     
         44 . The system according to the  claim 36 , wherein the processor is configured to analyze a fluidic resistance in the fluid pathway based on the signal of the sensor and to determine a failure of the infusion set based on the analyzing of the signal of the sensor. 
     
     
         45 . The system according to the  claim 36 , wherein the sensor is configured to measure the fluid pressure in the fluidic pathway. 
     
     
         46 . The system according to the  claim 45 , wherein the processor is configured to analyze a fluid pressure in the fluidic pathway and to determine a failure of the infusion set based on the analyzing of the fluid pressure. 
     
     
         47 . The system according to the  claim 36 , wherein the infusion set includes a transcutaneous device configured to be inserted into the body of the patient. 
     
     
         48 . A method for detecting a failure of an infusion set of a delivery system, the delivery system including,
 a reservoir storing the fluid to be infused to a body of a patient,   a fluidic pathway in fluidic communication with the reservoir,   a pumping device configured to move the fluid from the reservoir to the body of the patient,   a pressure sensor configured to monitor the fluid pressure in the fluidic pathway, and   an infusion set having a transcutaneous device in fluidic communication with the fluidic pathway and configured to infuse the fluid into the body of the patient,   wherein the method comprises the steps of:   receiving the pressure signal from the sensor;   analyzing fluid pressure in the fluidic pathway;   determining a failure of the infusion set based on the step of analyzing; and   prompting a change of the infusion set when the step of determining has determined the failure.   
     
     
         49 . The method according to the  claim 48 , wherein the system further includes an indication device configured to provide information to the patient, the method further comprising a step of
 displaying information corresponding to a quality of the infusion set, and/or a characteristic of the infusion site, and/or a fluidic resistance at the infusion site, and/or a remaining time before a change of the infusion set.   
     
     
         50 . The method according to the  claim 49 , wherein the step of displaying includes a displaying a color index which is be red, orange or red depending on a status of the infusion set. 
     
     
         51 . The method according to the  claim 49 , further comprising a step of:
 suggesting a behavior to the patient with the indication device.   
     
     
         52 . The method according to the  claim 36 , further comprising a step of:
