BIOCHEMICAL SIGNAL

� Biochemical, sometimes called biological chemistry, is the study of chemical processes in living organisms. � Biochemistry governs all living organisms and living processes. � By controlling information flow through biochemical signalling and the flow of chemical energy through metabolism, biochemical processes give rise to the incredible complexity of life.

� Example related to the biochemical signal is hormone. � A hormone is a chemical released by a cell or a gland in one part of the body that sends out messages that affect cells in other parts of the organism and is known as chemical messenger.

� For example: Gland : Islets of Langerhans in pancreas Hormone : insulin function : 1) decrease blood glucose level. 2) Increase glucose uptake and utilisation by cell

Medical Devices INSULIN PUMP

INSULIN PUMP � The insulin pump is used to automatically deliver basal insulin continuously, and bolus insulin at meal times by pressing the buttons. Before meals, a blood glucose value is entered into the pump to calculate the correction bolus to bring the blood glucose level back to the target value.

� when the blood sugar is increasing, a small correction bolus can be automatically delivered and a higher basal rate can be set; � when the blood sugar is decreasing, the basal rate can be halted to deny the quantity of insulin needed to bring the blood glucose level back up until the basal rate can be continued at a new lower rate
