Hybrid close loop system is an advanced technique having two parts as insulin pump with hybrid close loop and a sensory system guardian link three transmitter, which is designed to assist patients with type 1 diabetes in managing the glucose level. In auto mode, hybrid close loop system automatically adjusts the volume of insulin to be transferred with keeping a record of the quantity delivered in a given preset cycle. Hybrid close loop system can also adjust the volume of basal insulin i.e. the volume required when a person is not using an insulin pump. The device supplying quantity of 120 mg/dL of insulin, which further adjusts the hybrid close loop system to synchronize with the diet of the patient. Hybrid close loop system helps an individual to be aware of their glucose level, which makes them more independent in managing their daily diet plans with better compliance gradually. Furthermore, individuals at the risk of fluctuating glucose level at the night time are expected to be benefited more due to the hybrid close loop system's continuous glucose monitoring as well as the provision of insulin availability throughout the bedtime. Hybrid close loop system device can be a monopolistic rival for other insulin pump devices due to its hybrid and dual nature of monitoring the glucose level as well as to pump the amount of insulin required to maintain the absolute sugar level in the body. Nevertheless, the supporting factor for Medtronic hybrid close loop system is the priority access program, which enables diabetes affected population to get started with MiniMed 630G system with low cost on purchasing before it's official release in the market, which is dated in the year 2017.
