Description
(1) technical field
This utility model relates to a kind of piezoelectric-driven portable insulin infusion pump, and what especially a kind of piezoelectric motor drove can be at regular time and quantity to the portable insulin injection device of human injection's insulin, and it is stable to help diabetics to keep blood sugar concentration.
(2) background technology
Diabetes are that a kind of to continue to increase with blood sugar concentration be the metabolic disease group of characteristics, statistics shows nearly 200,000,000 diabetics in the world at present, and China's diabetics nearly 4,100 ten thousand ranks first in the world, and diabetes have become the mankind the 3rd or the fourth-largest healthy killer.Yet, present stage diabetes can not effect a radical cure, it is because blood samples of patients is in the complication that the environment of hyperglycemia time causes for a long time to healthy maximum harm.Therefore blood sugar control concentration prevents and treats the key that diabetic complication becomes the treatment diabetes.
At present, control of diabetes patient blood sugar concentration generally adopts two kinds of methods.The one, repeatedly subcutaneous injection of insulin, promptly once a day or for several times carry out subcutaneous injection of insulin; The 2nd, adopt the insulin strengthening treatment, do not stop in promptly one day 24 hours to the human body infusion of insulin.Experiment showed, the appearance of insulin strengthening treatment can the minimizing 76% left and right sides retinopathy through North America DCCT; Reduce the persistence microalbuminuria and reach 39% and 54% of more serious albuminuria incidence rate; Reduce by 60% clinical nephropathy incidence rate; The more effective blood sugar control concentration of energy prevents the generation with delaying complications of diabetes.
Insulin infusion pump claims again " continue subcutaneous insulin slow release system ".It can continually provide the basic insulin of measuring to blood samples of patients, and at the insulin of dining prerequisite for heavy dose, thereby blood sugar control concentration reaches the effect of simulation pancreatic secretion insulin.The utilization insulin infusion pump is exactly the main means of intensive insulin therapy.
Portable insulin infusion pump because its volume is little easy to carry, brings the misery to the patient except avoiding multiple injection, can also improve patient's quality of life greatly, therefore enjoys the favor of diabetics.
At present, portable insulin infusion pump adopts open loop mostly to the control of blood sugar concentration, do not adopt the wireless signal receiving device to detect blood sugar concentration in real time, so blood sugar control concentration is undesirable; Aspect water-tight, as patent name is " insulin pump ", publication number is the utility model patent of CN101138659A, its cavity body structure poor sealing, isolation useless between injection storehouse and the driving storehouse, the tube for transfusion joint does not adopt sealing ring with thread plug etc. with the external place that contacts, so waterproof effect is bad; Great majority adopt the small-sized electromagnetic type motors in the selection driving, as patent name is " insulin pump ", publication number is the utility model patent of CN2396824, it inevitably will design corresponding deceleration and drive mechanism thereby population structure bulky complex, and can make pump when work, inevitably will produce noise, wearing and tearing can cause precision slowly to reduce between the transmission nut screw rod; The insulin pump overwhelming majority is an imported product on the domestic market in addition, and price is all very expensive, and general patient cannot afford at all.
