The present invention relates to an automatically controlled insulin pump equipped with a sensor. More particularly, the present invention relates to an automatic control insulin pump equipped with a sensor capable of controlling the infusion amount and the infusion rate of meal insulin and basic insulin of the insulin pump.

Meanwhile, the automatic control insulin pump of the present invention sets and controls the infusion amount and infusion rate of meal insulin suitable for subcutaneous absorption state to individual diabetic patients through the pre-meal setting mode for meal insulin, and for basic insulin, basic insulin for type 1 diabetic patients. Basic insulin for type 1 diabetic and type 2 diabetic patients can be set at any time as needed. Basic insulin for type 1 diabetic is set at regular intervals. It is a controlled insulin pump.

Types of insulin for treating diabetic metabolic disorders can be generally classified into dietary insulin and basic insulin. Insulin-type insulin is usually injected into the human body three times a day on an empty stomach before meals. To prevent the rise, basic insulin is insulin that allows the action of insulin in the body to be maintained slowly for 24 hours.

Diabetes is a disease that occurs when our body does not make enough insulin or does not use insulin properly to convert blood sugar, or glucose, into energy. It is divided into type 1 and type 2 diabetes.

Type 1 diabetes is caused by the immune system misdiagnosing and attacking beta cells that make insulin in the pancreas as external invaders, usually causing sudden symptoms. It is commonly seen in children, called pediatric diabetes, but can also occur in adults.

Type 2 diabetes occurs when beta cells produce enough insulin but our body loses the ability to use them properly. It develops slowly and occurs mainly in middle age, called adult diabetes, but can cause overweight children.

Unlike the conventional method of injecting insulin 1-2 times a day, complications such as retinal lesions and renal lesions occur when treated with an active insulin treatment method that continuously injects insulin daily and maintains glycated hemoglobin in the normal range. It has been reported that the incidence has been considerably reduced, and that even if the complication has already occurred, aggressive insulin treatment can inhibit the progression of the complication. It has also been reported to reduce neuropathy and large vascular complications to some extent.

Therefore, active insulin treatment is recommended to prevent complications. According to a 1993 DCCT report, renal lesions were reduced by 34% in the group treated with active insulin, and the rate of progression from microalbuminuri to albuminuria was about 2%. Good blood sugar control also reduces kidney lesions. In a 1993 DCCT study, retinal lesions were reduced 69 percent in the active insulin treatment group compared to conventional treatment, and glycated hemoglobin was only 1 percent higher than normal in the active treatment group. Thorough control of blood sugar is the primary way to prevent neurological lesions.

Nine years of DCCT showed a 43% reduction in albuminuria and 56% reduction in albuminuria in the group treated with active insulin. In addition, atherosclerosis was less likely to occur when blood sugar was well controlled. Inadequate blood sugar control leads to atherosclerosis and also to hyperinsulinemia. DCCT reports also show that hyperglycemia is reduced if blood sugar control is poor.

Accordingly, the present invention is to provide an automatic control insulin pump for maintaining an appropriate insulin blood concentration in diabetics by injecting the above-described meal-type insulin and basic insulin in an optimal state.

In the case of dietary insulin, an appropriate amount of dietary insulin should be administered to each patient before or between meals. The necessity of adjusting the infusion rate according to the subcutaneous insulin absorption ability of the diabetic patient is raised. That is, when the subcutaneous absorption state of the diabetic patient is good, the insulin can be administered at a relatively high speed, and in this case, the insulin administration time can be shortened to minimize the pain and the like when the insulin is administered to the diabetic.

However, if diabetic patients have low subcutaneous absorption and insulin cannot be administered easily, meal insulin should be administered at a relatively low rate. As a result, it is difficult to expect sufficient treatment effect for diabetics.

Basic insulin is a type of insulin that allows diabetics to maintain their insulin function in the body continuously for 24 hours, and should be administered separately from pre-meal or diet meal insulin. Type 2 diabetes requires checking and adjusting the dosage on a 24-hour basis. In addition, since the injection method and the injection amount of the basal insulin are different in the injection method in type 1 diabetes and type 2 diabetes, a control method for controlling this properly and an automatic control insulin pump for implementing the same are required.

The technical problem to be achieved by the present invention is to develop an automatic control insulin pump for controlling the injection of dietary insulin and basic insulin suitable for individual diabetic patients through the insulin pump, the completion of the meal insulin infusion rate according to the degree of subcutaneous insulin absorption of individual diabetic patients In the case of basal insulin, the type 1 and type 2 diabetic patients through the insulin pump to continuously maintain the basal insulin action in the body continuously. In addition, apart from the meal insulin administered before meals or in the diet, patients with type 1 diabetes mellitus and type 2 diabetes have developed an automatic control insulin pump capable of checking and regulating the dose so that an appropriate amount of basal insulin is administered.

Accordingly, an object of the present invention is to buffer the rotation of the drive motor 107 to more precise rotation through the gear device 106, and then to move the plunger 102 through the movement of the plunger movement fixing nut to move the insulin in the insulin syringe 101. In a self-controlling insulin pump for injecting a very precise amount, the step of selecting a setting mode consisting of a meal insulin pre-meal setting mode and a basic insulin setting mode through the control panel 108 connected with the sensor 105, the amount of meal insulin injected And injecting and terminating the infusion rate according to the setting mode, and basal insulin is divided into type 1 diabetes basic insulin setting mode and type 2 diabetes basic insulin setting mode and injecting the same basic insulin according to the setting mode. And an automatic controlled insulin pump operative to check feedback the basal insulin infusion amount and infusion rate. A.

In addition, the automatic control insulin pump of the present invention is designed such that the insulin setting mode in the control panel 108 does not exceed a certain amount of the total insulin doses of the meal insulin and the basic insulin, and the meal insulin setting mode is also used for individual diabetics according to the pre-meal meal amount. It is characterized in that it is designed to control the infusion rate according to the diet insulin injection amount and the subcutaneous absorption state of diabetic patients suitable for the diet.

In addition, the automatic control insulin pump according to the present invention sets the basic insulin setting mode in the control panel 108 to 30 minutes to several hours for type 1 diabetes and 24 hours for type 2 diabetes so that the same amount of basic insulin is controlled. It is characterized by continuous infusion.

Hereinafter, the present invention will be described in more detail with reference to the drawings.

1 is a schematic diagram showing the overall configuration of an automatic control insulin pump equipped with a sensor of the present invention.

The rotation of the drive motor 107 is buffered with more precise rotation through the gear device 106, and then the insulin in the insulin syringe 101 is discharged in a very precise amount by the movement of the plunger 102 through the movement of the plunger movement fixing nut. By supplying to the connection tube insulin injecting unit 30 is to inject insulin into the human body. The driving of the driving motor 107 is controlled by the control panel 108 and the determination of the insulin infusion control mode of the control panel is operated by the operation button 110 attached to the upper surface of the display panel 109.

In addition, a liquid crystal display 111 is attached to the upper portion of the display panel 109 to perform display regarding insulin injection information to be injected and controlled. The battery power source 112 for driving the driving motor 107, the control panel 108, and the display panel 109 is inserted into the insulin pump. Therefore, the insulin pump of the present invention is an insulin pump capable of controlling the infusion amount by an electronic method.

Rotation of the plunger shift screw 103 is achieved by driving the drive motor through the signal from the control panel 108 and rotation of the gear unit. At this time, the sensor 105 measures the rotational speed of the plunger shift screw and the pressure at the time of rotation. Make it.

The amount of insulin in the insulin syringe is automatically measured. This measurement measures the insulin content in the insulin syringe by measuring the number of revolutions of the plunger shift screw. This measurement is made through the operation of the sensor 105 in connection with the control panel 108.

Figure 2 is a block diagram showing the driving state of the automatic control insulin pump equipped with the sensor of the present invention.

As shown in FIG. 2, overall insulin infusion and control can be performed by a control unit installed in the insulin pump control panel 108, input an injection mode, etc. through the operation button 110, and insulin injection control through the liquid crystal display 111. Display the status. In addition, the insulin injection and control signals of the control unit are transmitted to the motor 107 through the driving unit to move the plunger through proper rotation of the motor to inject insulin.

At this time, the injection amount check sensor is installed near the lower plunger gear to check and feed back the insulin injection amount to control the insulin injection amount. If the amount of insulin injected is greater than the infusion amount of the control unit, the information fed back through the check sensor can be used to control the insulin infusion amount by lowering the driving speed of the motor, and also less than the infusion amount of the control unit. If insulin is injected, it is possible to control the amount of insulin injected by increasing the driving speed of the motor by using the information fed back through the check sensor 105.

In addition, the regulation of insulin infusion rate is controlled through the rotational speed of the drive motor. In addition, when the injection speed is higher than the indicated speed, the controller lowers the driving speed of the motor by using feedback information. Increase the drive speed of the motor in the control unit using.

All these insulin pumps are driven and controlled by battery power.

Figure 3 is a flow chart illustrating a control method of an automatic control insulin pump equipped with a sensor of the present invention.

As shown in Figure 3, the insulin injection control method of the present invention is composed of a meal insulin pre-meal setting mode and a basic insulin setting mode, driving the drive motor according to the meal and the basic insulin injection amount injection signal through this setting mode and meal insulin And basal insulin.

In the case of meal insulin, the injection is terminated when a certain amount of meal insulin is injected according to the pre-meal injection mode. That is, in the case of meal insulin, a certain amount of meal insulin is injected from pre-meal to mealtime, and the injection is terminated, and another meal insulin is injected from a meal before meal to a certain amount at the next meal.

Basic insulin is divided into type 1 diabetes basic insulin setting mode and type 2 diabetic basic insulin setting mode and controls the amount of infusion by integrating different administration modes according to the type of diabetes. In the type 1 diabetic basic insulin setting mode, the injection amount is set in units of hours and the set injection amount is continuously injected in the same amount. On the other hand, in the type 2 diabetic basic insulin setting mode, the dose is set in units of 24 hours, and the set amount is continuously injected in the same amount for 24 hours.

The meal and basal insulin modes are checked by the insulin dose check sensor and fed back to the setting mode. Therefore, if more or less insulin is injected than the desired setting, the amount is automatically adjusted through this feedback. In addition, data such as various blood sugar levels may be input before setting meal insulin and basal insulin to control feedback of the amount of insulin injected.

An effect of the present invention is to provide a self-controlling insulin pump for controlling the infusion of meal insulin and basal insulin suitable for each individual diabetic patients through the insulin pump, to control the completion of the meal insulin infusion rate according to the subcutaneous insulin absorption of the individual diabetic patients In the case of basal insulin, the type 1 and type 2 diabetic patients through the insulin pump continuously to maintain the basic insulin action in the body continuously. It is another object of the present invention to provide an auto-controlled insulin pump capable of checking and regulating the dose so that an appropriate amount of basal insulin is administered to patients with type 1 diabetes and type 2 diabetes separately from meal insulin administered before or during meals.
