Description
Technical field
The present invention relates to a kind of Intelligent insulin pump, and in particular to a kind of pump body structure of Intelligent insulin pump.
Background technology
In in 1992, a kind of insulin pump is invented by Medtronic Inc. of the U.S., this pump has a larger pump housing,
It is longer by one（About 35cm) liquid-transport pipe-line be connected with body, subcutaneous abdomen is embedded in by a lienable injection needle,
By controlling button control injection dosage and injection time on the pump housing manually, with the control software regulation control insulin in the pump housing
Basal dose.The relatively subcutaneous manual injection's insulin of this pump has advantages below：1st, blood glucose can be effectively controlled, because having
The daily value of cutting edge of a knife or a sword before the meal injection is outer, the injection of the aqua amount basal insulin of also up to a hundred times, can the small time control of effective whole day 24
Blood glucose processed.Particularly to the patient of dawn blood glucose rise phenomenon, the rise of blood glucose more can be effectively controlled to human organ
Infringement；2nd, patient is facilitated to reduce frequency injection.After this pump, patient can change shot position within one to two weeks, subtract significantly
Lack manual injection's number of times, improved the quality of life of patient, reduce superinfection caused by injection and because injecting to skin
The damage that skin is caused.But there is following defect simultaneously in this pump：1st, it is extremely inconvenient when patient uses, because the pump housing is larger, Huan Zheyi
As be all to carry piggyback or hang over loins on the arm, patient takes exercises, has a bath, all inconvenient during sleep, and the pump housing does not have water-proof function, less
It the sports such as significantly can move and swim；2nd, patients' privacy can not be protected, patient must when injecting peak insulin before the meal every time
Must on the pump housing button press, because the pump housing is larger, when summer and autumn temperature is high, the pump housing exposure, patient can not protect illness it is hidden
It is private；3rd, it is expensive, the insulin pump price of current import all in 4-6 more than ten thousand, monthly consumptive material about more than 400-600 members,
Expense burden is added to patient；4th, hypoglycemia can not effectively be controlled.Because connecting pipe is longer, patient is in last dressing casket
When due to external pressure it is larger, residual liquor can disposably enter subcutaneous, cause excess injection to cause hypoglycemic reaction；5th, pipeline
Waste larger during replacing, due to being that every milliliter of high concentration insulin pumping admixture includes 200 units, monthly to change pipeline 2 to 4 times,
Per the secondary unit of waste insulin about 20 to 40.
The content of the invention
It is an object of the invention to provide a kind of integrated level height, small volume, lightweight, connecting pipe be short, injection volume can essence
The insulin really controlled attaches pump.
Pump is attached the invention discloses a kind of intelligent insulin, it includes shell and the insulin pump being packaged in its inner chamber
Device and the medicine casket with piston are sent, insulin pumping installations includes the power part and drive disk assembly being sequentially connected, drive disk assembly
Terminal link be connected with the piston of medicine casket, make piston can be moved along the inwall of medicine casket by insulin preparation extruding pump out it is percutaneous under
In remaining needle injection patient's body.
The shell is close-shaped U-shaped body, is surrounded by corresponding U-shaped upper shell and lower house sealing, upper shell and
The sealing dividing plate parallel with the parallel side wall of upper and lower casing two is provided between lower house and divides the housing into two independent chambers,
The U-shaped conduit of sealing dividing plate is provided through in shell.

Made into material, its one end is inserted in the U-shaped conduit, and the piston of the other end and the medicine casket is detachably connected as a single entity, transmission
Side arrangement of the screw mandrel along the U-shaped parallel side wall of conduit two, transmission nut is connected on drive lead screw, the side wall connection of transmission nut
Have and offer bar-shaped trough parallel with it on drive block, U-shaped conduit at correspondence drive lead screw position, in drive block insertion bar-shaped trough
It is connected as a single entity with the corresponding end-faces of flexible piston rod.
The drive lead screw as the gear reduction box output shaft or pass through the defeated of shaft joint and gear reduction box
Shaft is connected, and the convert rotational motion of drive lead screw promotes flexible piston rod and the medicine casket for the linear motion of transmission nut
Piston move forward.
There is the angling hole of respective angles on the shell at the outlet of the correspondence medicine casket outer end, inserted for remaining needle
Enter, corresponding sealing ring is configured at angling hole.
The control for being connected to the micro motor is there also is provided in chamber in the shell residing for the correspondence power part
Circuit circuit board processed；The USB interface and illuminating lamp being connected with control circuit circuit board are connected with shell.
The bottom surface of the housing lower shell is pasted on patient's lower abdomen skin as attaching face by biogum, upper shell
The replacing that slidable seal cover board is easy to medicine casket is provided with the correspondence medicine casket.
The shell and U-shaped conduit, sealing dividing plate are one-time formed carbon fiber composite materials single piece, the inwall of shell
It is respectively arranged with the correspondence medicine casket, micro motor, gear reduction box and drive lead screw position one-time formed corresponding solid
Determine structure.
The convert rotational motion of drive lead screw is transmission using drive lead screw and driving screw-nut structure by the present invention
The linear motion of nut, then flexible piston rod is promoted by transmission nut and then the piston that carries of medicine casket is promoted forward
It is mobile, the insulin preparation extruding in medicine casket is pumped out in percutaneously lower remaining needle injection patient's body, remaining needle directly with medicine casket
Outlet is connected, and residual liquor is few, be avoided that prior art because connecting pipe length and may caused by hypoglycemic reaction, improve and suffer from
The security of person, moreover it is possible to avoid the waste of decoction, saves expense.
In order that drive lead screw produces low-speed rotation, gear reduction box is configured, the power set of gear reduction box are adopted
With micro motor, use requirement so can be both met, space-consuming can be reduced again.
