Embodiment Construction

[0031] The technical solution of the present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings.

[0032] According to the usual dose of insulin, 300 units of insulin (300U) is 3mL, it can be seen that the volume of each unit (1U) of insulin is 3ml / 300=10μL, and distilled water is used instead of insulin injection to detect the measurement characteristics of insulin pumps. The density is 1g / cm 3 The volume of the infused liquid can be converted by measuring the mass difference of the insulin pump before and after the infusion with a load cell with milligram-level accuracy, so as to further convert the insulin injection volume.

[0033] A method for measuring and calibrating an insulin pump, comprising the following contents:

[0034] Such as Figure 2-3 As shown, an insulin pump measurement and calibration platform is constructed: including an electronic weighing module 1 , a flow control module 2 , a pressur...

Abstract

The invention discloses a metering and calibrating method for an insulin pump, which includes detection of indication error of basal rate infusion, detection of indication error of large-dose infusion, error and repeatability of indication of infusion flow, detection of infusion pressure safety, and temperature alarm Detection, drug storage residual alarm, infusion obstruction alarm and other steps; the invention solves the problems of insulin pump basal rate infusion indication error, large dose infusion indication error, infusion flow indication error and repeatability, and infusion pressure safety The detection and traceability of the metering characteristics such as sex; solved the detection and traceability of the real-time infusion flow indication error items of the insulin pump.

Description

technical field [0001] The invention relates to a measurement calibration method, in particular to an insulin pump measurement calibration method. Background technique [0002] The insulin pump is an instrument controlled by a microcomputer to pump exogenous insulin into the human body in a timely, quantitative and precise manner. It simulates the physiological mode of insulin secretion by the healthy pancreas of the human body. It is equipped with a drug storage device. Through the infusion line connected to it, insulin is continuously injected into the subcutaneous of the user according to the dose required by the human body, so as to keep the blood sugar stable throughout the day. In order to achieve the purpose of controlling diabetes. At present, insulin pumps are more and more used in the clinical treatment of diabetic patients, and have received good curative effect. [0003] The design performance of an insulin pump is extremely important, especially its dosing acc...
