Description

INJECTION CONTROLLER HEATH SYSTEM AND METHOD FOR GENERAING BLOOD GLUCOSE RELATED ALARMS

Embodiments herein relate to infusion controllers, health systems, and methods of generating blood glucose related alarms.

In general, a drug injection device such as an insulin injection device is used to inject a drug solution into a patient's body. Although such a drug injection device is sometimes used by professional medical staff such as doctors or nurses, in most cases, it is used by ordinary people such as patients themselves or guardians. Diabetic patients, especially pediatric diabetic patients, need to inject a drug solution such as insulin into the body at a predetermined interval. Therefore, a drug injection device in the form of a patch used by attaching to the human body for a certain period of time has been developed. Such a drug injection device may be used in a state of being attached in the form of a patch to a human body such as the patient's abdomen or waist for a certain period of time.

The drug injection device may be designed to inject insulin under the control of an injection amount program designed in consideration of the patient's condition. An unexpected risk may arise if the insulin programmed by the drug injection device is injected.

Therefore, the drug injection device needs to inject insulin in consideration of the low blood sugar level of the patient.

In another embodiment, the alarm output determiner 253 determines that the blood sugar rise rate is equal to or greater than a preset maximum rise rate, and generates a blood sugar alarm corresponding to the magnitude of the blood sugar rise rate in response to the blood sugar rise rate being equal to or greater than the maximum rise rate. can decide When the blood sugar rise rate is less than the maximum rise rate, when the blood sugar rises very slowly, the blood sugar alarm may be set to NULL to not generate the blood sugar alarm.

The alarm output determiner 253 may determine a blood sugar alarm representing a level corresponding to a blood sugar drop rate (or a blood sugar rise speed) and may set an output method of the blood sugar alarm differently according to time sections. For example, the alarm output determiner 253 may implement to gradually lower the output intensity of the blood sugar alarm when the blood sugar alarm corresponds to a high activity time section set by the user based on the current time.

The alarm output determination unit 253 determines a blood sugar alarm representing a level corresponding to a blood sugar drop rate (or a blood sugar rise speed), and when it corresponds to an inactive time period set by the user based on the current time, It is possible to generate an alarm output signal that is output by gradually increasing the output strength.

The alarm output determiner 353 may determine a blood sugar alarm representing a level corresponding to a blood sugar drop rate (or a blood sugar rise speed) and set an output method of the blood sugar alarm differently according to a current time section. For example, the alarm output determiner 353 may implement to gradually lower the output intensity of the blood sugar alarm when the blood sugar alarm corresponds to a high activity time section set by the user based on the current time.

The alarm output determination unit 353 determines a blood sugar alarm representing a level corresponding to a blood sugar drop rate (or a blood sugar rise speed) and, if it corresponds to an inactive time period set by the user based on the current time, It is possible to generate an alarm output signal that is output by gradually increasing the output strength.
