Description
Technical Field
The utility model relates to the technical field of medical equipment, in particular to an artificial in-vitro pancreas based on insulin and glucagon.
Background
Diabetes is currently largely classified into type one diabetes (insulin-dependent diabetes mellitus) and type two diabetes (non-insulin-dependent diabetes mellitus). For type II diabetics, the light person is generally treated with oral medications, such as oral metformin and the like. Heavier patients are generally treated with insulin pens. According to the different medicines used by insulin pens, the insulin pen is matched with different physique of patients and is divided into long-acting insulin, short-acting insulin and mixed insulin. Different drugs have different times of insulin action to meet the treatment of patients with different foods and different conditions. Because of the variety of insulin and the complexity of the patient's own illness and the relationship with the patient's diet, in the technology of strengthening treatment of diabetes in general, the patient must be strictly required to control the diet, and the meal is timed and quantitative, and the variety of the meal cannot be changed too much. Which would otherwise lead to a drastic change in the blood glucose of the patient and thus present a hazard.
In addition, when the insulin pen is used for treatment, the patient needs to inject the medicine for 4 times a day in general, namely, short-acting insulin is respectively injected once before three meals in the morning, in the middle and at night, and then the patient needs to inject long-acting insulin once before sleeping. Meanwhile, blood glucose is measured by adopting fingertip blood before three meals. Blood glucose was also measured 2 hours for three meals, and one blood glucose was also measured before sleeping. Thus calculated, the patient measured blood glucose and injected insulin for a total of 11 needles a day. This is conceivable to be very painful for the patient.
In addition, there is an insulin pump on the market at present, which achieves the purpose of making the blood sugar of the patient more stable through a mixed injection mode of basal rate injection and preprandial large dose injection. However, this device has the fatal disadvantage that it causes fatal hypoglycemia to occur when the patient moves vigorously once, or does not eat a prescribed amount of food within a prescribed period of time. Because the traditional insulin pump can only inject insulin simply, the blood sugar can be reduced in one direction only. Once the blood glucose is too low, it is no longer possible to raise the blood glucose. While hyperglycemia leads to chronic deterioration of the patient, hypoglycemia is likely to cause the patient to lose consciousness instantaneously, and even cause death. The risk of hypoglycemia is far higher than that of hyperglycemia. Whereas conventional insulin pumps do not.
And the control operation and display content of the traditional insulin pump are basically on the pump body. Moreover, since the conventional insulin pump adopts an assembly mode that the injection needle is closely connected with the pump body, the injection tube is not separated from the pump body, and bacteria can enter a connecting position due to forced separation. Patient handling and viewing is inconvenient. In some public places, some patients cannot at all do the unhook to adjust the settings above the insulin pump. Thereby bringing great inconvenience to the patient.
Whatever the above treatment, all preconditions are based on the patient's strict diet control. Without strict timing and quantitative diet and planning, light people can lead to large blood glucose fluctuations, and heavy people can lead to hypoglycaemic shock, even life threatening. But also strict exercise planning must be specified, otherwise a risk of hypoglycemia is created.
