Infusion pump having alarm features

Abstract

An infusion pump for delivering medicament to a user. The pump comprises a pump mechanism, a memory and a processor The processor can be programmed to generate an alarm signal based on various determinations. For example, a delivery limit alarm can be issued when it is determined that an amount of medicament delivered with the pump mechanism within a predetermined length of time exceeds a medicament delivery limit amount. Alternatively or in addition, a low cartridge reservoir alert can be issued in response to determining that medicament remaining in a reservoir is equal to a value stored in memory.

         21 . A pump for delivering a medicament to a user, the pump comprising:
 a pump mechanism;   a memory; and   a processor adapted to control the pump mechanism to deliver the medicament to the user and communicatively coupled with the memory, the processor configured to:
 determine a medicament delivery limit amount; 
 associate the medicament delivery limit amount with a predetermined length of time; and 
 issue a delivery limit alarm in response to determining that an amount of medicament delivered with the pump mechanism within the predetermined length of time has exceeded the medicament delivery limit amount. 
   
     
     
         22 . The pump of  claim 21 , wherein the predetermined length of time is one hour. 
     
     
         23 . The pump of  claim 21 , further comprising a user interface and wherein the processor is further configured to determine the medicament delivery limit amount through a selection made through the user interface. 
     
     
         24 . The pump of  claim 23 , wherein the processor is further configured to present a range of medicament delivery limit amounts from which the selection may be made. 
     
     
         25 . The pump of  claim 24 , wherein the range is between 2 units and 100 units of medicament. 
     
     
         26 . The pump of  claim 21 , wherein the medicament is insulin. 
     
     
         27 . A pump for delivering a medicament to a user, the pump comprising:
 a pump mechanism;   a reservoir of medicament, the pump mechanism configured to deliver the medicament in the reservoir to a user;   a memory; and   a processor adapted to control the pump mechanism and communicatively coupled with the memory, the processor configured to:
 store in memory a value associated with medicament remaining in the reservoir; 
 determine that the medicament remaining in the reservoir is equal to the value stored in memory; and 
 issue a low cartridge reservoir alert in response to determining that the medicament remaining in the reservoir is equal to the value stored in memory. 
   
     
     
         28 . The pump of  claim 27 , wherein the value is a volume of medicament remaining in the cartridge reservoir. 
     
     
         29 . The pump of  claim 27 , further comprising a user interface and wherein the processor is further configured to receive a selection of the value to be stored in memory through the user interface. 
     
     
         30 . The pump of  claim 29 , wherein the processor is further configured to present a range of values from which the selection may be made. 
     
     
         31 . The pump of  claim 30 , wherein the value is a volume of medicament remaining in the reservoir and the range is between 5 units and 50 units of medicament. 
     
     
         32 . The pump of  claim 27 , wherein the medicament is insulin.
