Abstract
The invention discloses a disposable pneumatic dual-tube insulin injection pump, which consists of dual micro tubes, a flexible medicinal bag, a sensor, an electromagnetic valve, a simple control system shell, an electric control pneumatic pump, a motherboard chip module and a USB (Universal Series Bus) interface. The cost of the pump is about RMB 300 yuan, and the selling price is RMB 400-500 yuan. Trade-in is available, so that the burden of patients is relieved. Meanwhile, components and elements are delicate and compact, and used elements are small in sizes. Compared with the conventional insulin pump, a large space is available for storing liquid medicaments under the condition of the same outline, and the medicinal dose is up to 50ML, which can be used for 2 months by patients. Meanwhile, an accurate micro-tube control technology is applied, so that the liquid medicament exhausting time can be accurately calculated, early warning is realized, and liquid insulin is replaced. In the disposable pneumatic dual-tube insulin injection pump, a liquid crystal screen, a manual key operating system, relevant circuits and electronic elements in the conventional insulin pump are avoided, so that the cost is lowered greatly, and the internal space of the product is enlarged.
Description
Technical field:
The present invention relates to one: the two microtubule insulin injection pumps of disposable air pressure.Be mainly used in diabetics, instant insulin injection, to reduce control blood sugar for human body.
Background technology:
The invention technology the present invention relates to: having invented Controlled by micro computer motor increases pressure technology; Invent the two-tube instantly changing injection of microelectronics instruction flow control technique.
Relate to the technology of application: software programming application technology; Microelectronics Radio Transmission Technology; Microelectronics storage application technology; Aeromechanics technology; Electric energy conversioning mechanical energy technology; Fluid flow control technology; Organic material hygiene and health technology; Product reclaiming technology.
The general dose of traditional insulin pump is 5ML (motor, mechanical transmission mechanism etc. take up room larger), approximately can maintain the insulin use amount in one week of patient.And, need change dose a week one time, operate more loaded down with trivial details, general patient oneself operate interpolation insulin, the probability of infection is larger, often occurs secondary disease.Due to traditional insulin pump, one can use 4 years, after changing dressings, pricks again a pinprick simultaneously at every turn, and user is more painful.And, cost is very expensive, general price is more than 20,000 yuan, imported product is 80,000 yuan of left and right, meanwhile, there is again the monthly consumptive material expense of 200 yuan-300 yuan, can only use 4-6 for one, that patient is difficult to bear economically, so generally the poor patient of economic capability can select abandoning cure; And no matter patient morbidity any stage, these expenses all need disposable input, are all great burdens to patient and family members.Product of the present invention, by two microtubules, soft medicated bag, sensor, electromagnetic valve, simple control system shell and automatically controlled pulsometer with form with mainboard chip module and USB interface, cost is greatly about 300 yuan of left and right, price is at 400 yuan-500 yuan, and exchange old for new, alleviate patient's burden.Meanwhile, this product is due to the exquisiter compactness of parts, element of invention, and the component size of use is less, with traditional insulin pump, in the situation of equal profile, very large space is used for storing medicinal liquid again, and dose can arrive 50ML, patient can use 2 months, simultaneously owing to having used the precision Control Technology of microtubule, so, can be by calculating the time that medicinal liquid exhausts that obtains accurately, report to the police in advance, change insulin medicinal liquid.This product does not have traditional insulin pump LCD screen and manually button operation system and associated circuits, electronic component etc., thereby has reduced greatly cost, has expanded the inner space of this product.The working procedure of this product, by doctor's setting program being input on the chip module of insulin pump on computers.
Microtubule flow-control principle: microtubule resistivity S=0.001736/d^5.3; (ρ g) for the head difference H=P/ at microtubule two; Flow Q=(H/sL) ^ (1/2) infusion amount V=Q*t; Therefore, infusion amount V=(P/ (ρ * g)/(0.001736/d^5.3*L)) ^ (1/2); So can pass through controlled pressure P and microtubule diameter d, microtube length L and time can reach the object of controlling infusion amount V; Meanwhile, medicated bag capacity is known, fixed according to designing and calculating, is generally 50ML; Except pressure and length L, outside microtubule diameter d, other is constant; So, can calculate the time T that medicated bag is used up by formula, because the flow Q of each time period is different, so the time T that medicated bag is used up is the accumulated value of each time, and according to patient's difference setting, also there is difference the concrete time; Program of the present invention is to calculate to control medicinal liquid infusion amount with above-mentioned principle, and the time T of using up by accumulation calculating medicated bag, reports to the police in good time, and prompting patient changes medicinal liquid or equipment; In formula: the time: t; Microtubule diameter: d; Microtube length: L; Pressure (pressure): P; Medicinal liquid density: ρ; Acceleration of gravity: g; This equipment at least can use 2 months, as disposable use equipment, also can exchange old for new, and reclaiming.
This product in use, doctor is according to patient's blood sugar content, utilize special-purpose software, set on computers patient section sometime inject insulin quantitatively, and by USB delivery outlet, be input in the chip of this product, like this, chip will be according to the time period of setting, in the time that patient has a dinner, will the thicker microtubule insulin injection of instruction, at ordinary times with regard to the thinner microtubule insulin injection of instruction.
The content of invention:
Technical problem to be solved by this invention is, having overcome traditional insulin pump dose is only 5ML, and, needing change dose a week one time, the probability of infection is larger, often occurs secondary disease.Meanwhile, in order to increase the capacity of insulin, innovation Controlled by micro computer motor increase pressure technology; Invent the two-tube instantly changing injection of Controlled by micro computer flow control technique.
