Description
Technical field
The present invention relates to a kind of infusion pump, more particularly to a kind of help the round-the-clock stabilizing blood sugar that maintains of diabetic
Paste formula insulin infusion pumps.
Background technology
Insulin infusion pumps be simulate human pancreas secreting function, according to human body need dosage by insulin constantly
The subcutaneous of user is injected, keeps whole day glucostasis, to reach the purpose of control diabetes.Insulin pump in treatment and routine
Injection treatment is compared, and has the advantages of many unique:Blood glucose can be preferably controlled compared with multiple injection with one day, through statistics, pancreas
The HbA1c (glycosylated hemoglobin) of island element infusion pump user is less than the patient having an injection.Importantly, their blood glucose fluctuation
Amplitude is small, tends to normal level.The worried foundation rate for reducing infusion short-acting insulin of hypoglycemia replaces protamine zine insulin treatment sugar
Urine disease, then also without having dinner on time, having a meal can postpone or cancel, and occur without having to worry about hypoglycemia.Person's blood glucose suppression ratio of wearing pump
It is shallower, Hypoglycemic symptoms can be found early, can be reduced others as far as possible and be helped.
At present, traditional insulin infusion pumps mainly by pump, small syringe and the woven hose group that is attached thereto into.Syringe
After being fitted into pump, the guiding pin of connected woven hose front end is penetrated with note pin device subcutaneous (conventional is stomach wall) of patient, then by
The auger motor of battery power insulin pump promotes the piston of small syringe that injection of insulin is entered into human body.Have the disadvantage that:
1) volume is big, weight is big, not readily portable;
2) woven hose is longer, during patient activity, be easily wrapped in, greatly limit resource-user cost method;
3) woven hose increases the use cost of user as consumptive material.
The content of the invention
It is an object of the invention to provide a kind of infusion pump, it has small volume, in light weight, use cost low and user
The characteristics of freedom of movement, to solve above mentioned problem existing for insulin infusion pumps in the prior art.
To use following technical scheme up to this purpose, the present invention:
A kind of infusion pump, it includes housing;Power supply in housing, motor, drive component, control assembly are arranged at, and
The drug storage component being at least partially housed in the housing;
The extrusion infusing pipeline and infusion needle for decoction output are provided with the drug storage component, the motor is in the control group
Under the control of part, the drug storage component is driven to export decoction from infusion needle by the drive component,
The infusion pump also includes the component that pastes being arranged on the housing, and the infusion pump pastes component by described
It is covered on the skin of patient's areas adjacent to be injected.
Especially, the infusion pump also includes being used for the controller separately positioned with the housing for setting running parameter,
The controller is communicated by wireless connection with the control assembly.
Especially, described to paste component with the housing by the separable connection of thread gluing, it is easy using double faced adhesive tape to avoid
It is adhered on housing, without cleaning.
Especially, the drug storage component includes drug storage housing, the infusion needle and the drug storage housing split settings, both
Between connected by very short flexible infusion line road, infusion pump does not interfere with the syringe needle of insertion human body when moving.
Especially, the drug storage component includes drug storage housing, and the drug storage housing is made of clear material, and the drug storage
One end of housing has extended downwardly clamping joint, and the other end sets up infusion needle, coordinates clamping joint in setting card on the housing
Groove, and piston is set in the clamping joint, the drug storage housing is stuck in the neck on the housing by clamping joint.
Especially, the drive component includes injection push rod, and external thread section is provided with the output shaft of the motor, described
Injection push rod by inner screw sheath for setting in it outside the output shaft of motor, by interior during the output shaft rotation of the motor
External screw thread, which coordinates, promotes the movement of injection push rod.
Especially, the infusion pump is additionally provided with warning device, and the warning device is vibrator, alarm lamp or alarm loudspeaker
Any one or several combinations.
Especially, the vibrator is arranged in the housing, and the alarm lamp and alarming horn are arranged at the housing
Or controller it is any on.
Especially, the weight of the infusion pump in 35g between 55g, when the infusion pump of the weight range wears human body
Feel without obvious, and it is difficult for drop-off after thread gluing.
Especially, radio communication is carried out by low-power consumption bluetooth 4.0 between the controller and the control assembly.
Beneficial effects of the present invention are that the infusion pump sets very short infusion pipeline compared with prior art, directly against
Be overlying on human body to patient implement injection of insulin, not only small volume, it is in light weight, be easy to carry;And wearer can be ensured
Freedom of movement;Reduce use cost.
