Embodiment Construction

[0031] In order to achieve the above-mentioned technical objectives and make the features and advantages of the present invention more understandable, various implementation modes of the present invention will be specifically described in conjunction with the following examples.

[0032] combine figure 1 An embodiment of the closed-loop control system of the present invention is given. figure 1 A schematic diagram showing a patient wearing the device in this embodiment: a continuous blood glucose monitoring system 1 for real-time monitoring of the patient's continuous blood glucose, and a patch pump 2 for infusing insulin to the patient. These two devices each have a processor that communicates with the processor of a portable handset 3 for receiving signals, processing and displaying data, and sending instructions. At least one motion sensor is set in one, two or all of the continuous blood glucose monitoring system 1 , the patch pump 2 and the handset 3 , which will be desc...

Abstract

The invention provides a loop close control method in artificial pancreas and the artificial pancreas adopting the method. The method comprises the following steps that at least one motion sensor senses the activity level of a patient, and provides a signal to at least one processor; the processor part adjusts a series of related algorithm based on the signal, so that more accurate and more reliable data is provided and taken as the basis for an ideal treatment plan, the processor sends an instruction for enabling the artificial pancreas to automatically carry out the corresponding operation,and thus the loop close control is realized.

Description

technical field [0001] The present invention mainly relates to medical equipment, more precisely, relates to a system and method for realizing closed-loop control in artificial pancreas. Background technique [0002] In a normal healthy person, the pancreas produces insulin in response to elevated blood sugar levels and releases it into the blood. Beta cells present in the pancreas produce and secrete insulin into the blood as needed. If the beta cells lose function or die, the condition is called type 1 diabetes, and if the beta cells produce insufficient amounts of insulin, the condition is called type 2 diabetes, and insulin must be supplied to the patient's body from another source. [0003] Traditionally, since insulin cannot be taken orally, medicinal insulin is mainly used by injection. Recently, there has been an increase in the use of infusion pumps, especially insulin pumps for infusion of insulin in diabetic patients. For example, an external infusion pump can ...
