The artificial pancreas system organically combines the glucose automatic sensing system CGM and the automatic injection system, effectively realizes the integration of detection and treatment, provides patients with safe and proper accurate dosage insulin injection with accurate dosage, and ensures that the patients can obtain the best treatment effect.
Description
Technical field
This utility model relates to a kind of system that is used for injecting to human body medicine.
Background technology
General at present employing insulin pump carries out insulin to human body and injects automatically.Existing insulin pump generally comprises disposable medicine storage, disposable notes conducting tube, injecting mechanism, reducing gear, structures such as control circuit.Yet the insulin pump of Chu Shouing is mainly taked two kinds of injection startup forms on the market: the one, and regularly injection; The 2nd, time of diet and what to start injection button by the patient according to.Do not come insulin injection because be not according to blood sugar concentration, so existing insulin pump is accurate blood sugar control concentration at all, especially patient's blood sugar concentration in bed is difficult to control, can't reach optimum therapeuticing effect, more can't allow patient body keep the optimum health state.Therefore be badly in need of a kind of intelligence and cheap insulin-injecting system on the market, can determine the injection volume of insulin automatically, but patient's safe and continuous is used and be need not manual intervention according to the blood sugar concentration detected value.
Summary of the invention
The purpose of this utility model is the defective that exists at prior art, and a kind of insulin-injecting system that can detect blood sugar concentration automatically is provided.
For achieving the above object, this utility model has been taked following technical scheme:
The artificial pancreas system, is used to analyze the glycemic control system of blood sugar concentration and calculating optimum dosage and the automatic injecting systems that human body is carried out injection of insulin according to the injection volume signal at the glucose automatic induction system CGM that comprises serially, automatically human blood glucose concentration is detected; Described glucose automatic induction system CGM and glycemic control system connectivity; Described glycemic control system is communicated with injecting systems automatically.
This system can detect blood sugar concentration automatically, and can determine the number of times and the dosage of insulin injection according to patient's blood glucose value concentration; Simultaneously, it also can be injected according to number of times that configures and dosage.Before insulin injection, to the blood sugar concentration of human body be detected, determine whether the dosage of injecting and injecting according to testing result.When detected blood sugar concentration belongs to normal range, abandon this injection; Cross when low when blood sugar concentration, determine the dosage of injecting according to the calculating of glycemic control system.Thereby realized full automatic closed loop control, carried out the injection of exact dose insulin, optimization ground control patient's blood sugar concentration.
Above-described glycemic control optimum system choosing adopts following system structure: auxilliary CPU, CGM interface, bin, vibrating device, phonetic alarm, display, button and communication interface are communicated with host CPU respectively, and battery is powered to whole system; The CGM interface is communicated with glucose automatic induction system CGM; Host CPU is communicated with automatic injecting systems.
Above-described automatic injecting systems preferably adopts following system structure: fluid reservoir, injection mechanism, interface tube, tube for transfusion and syringe are installed successively; The liquid storage pick off is installed on fluid reservoir; Described injection mechanism also links together with driver, and driver is communicated with controller; Described controller and liquid storage pick off and glycemic control system connectivity.
This utility model organically combines glucose automatic induction system CGM and automatic injecting systems, realized the integrated of detection and treatment effectively, for the patient provides safety, suitable, the accurate injection of insulin of dosage, make the patient can obtain best therapeutic effect.
Description of drawings
Fig. 1 is the operation principle block chart of this utility model embodiment;
Fig. 2 is the structure block chart of this utility model embodiment;
Fig. 3 is the control flow chart of this utility model embodiment.
The specific embodiment
Below in conjunction with drawings and Examples this utility model content is described further.
As shown in Figure 1, the artificial pancreas system is made up of the three parts that are communicated with successively: glucose automatic induction system CGM, glycemic control system and automatic injecting systems.The blood sugar concentration of the automatic human body of glucose automatic induction system; Glycemic control systematic analysis blood sugar concentration and calculating optimum dosage; After determining optimum dosage, injecting systems carries out the injection of exact dose insulin to human body automatically.
As shown in Figure 2, whether the insulin in the fluid reservoir is injected by injection mechanism control, passes through interface tube, tube for transfusion, syringe during injection, to human injection's medicine; Dose in the fluid reservoir is detected by the liquid storage pick off in real time by host CPU, and detected dose result is shown on the display; Injection mechanism passes through controller, its action of driver control by host CPU; Glucose automatic induction system CGM delivers to host CPU with detected blood sugar concentration by the CGM receiving port.Bin, vibrating device, phonetic alarm, display, button, communication interface directly are connected with host CPU; Host CPU also is connected with auxilliary CPU, realizes intercommunication; Battery is powered to whole system.
As shown in Figure 3, the control flow of present embodiment is as follows:
1) after the start, detect whether finish setting earlier: if finish, then redirect; Otherwise need the manual major parameter that is provided with;
2) carry out major cycle after reading the major parameter of setting;
3) regularly detect after the blood sugar concentration time arrives, detect blood sugar concentration: if blood sugar concentration is normal, then preserve data, get back to circulation; If undesired, then calculate dosage, after the injection, preserve data, get back to major cycle;
4) set arrive inject time after, detect blood sugar concentration: if blood sugar concentration is normal, then preserve data, get back to circulation; If undesired, then calculate dosage, after the injection, preserve data, get back to major cycle.
The advantage of present embodiment is:
1) host CPU and auxilliary CPU calculate simultaneously, detect blood sugar concentration in real time, and according to blood sugar concentration accurate Calculation dosage;
2) dose detects in real time, and demonstration, warning function are arranged;
3) incorporate exterior design realizes incorporate function;
4) has waterproof, low-power consumption and advantage such as easy to maintenance.
