Description

A kind of insulin intranasal medicator

Technical field

The utility model belongs to medicine instrument technical field, is specifically related to a kind of insulin intranasal medicator.

Background technology

Insulin is widely used in treating diabetes. What is interesting is, large quantity research shows: insulin also has powerfulNeuroprotective function: diabetes have been considered to as sacred diseases such as Alzheimer disease, Parkinson's, vascular dementiasAn important risk factor is found the impaired and insulin receptor of insulin signaling desensitization phenomenon in the brain in patients of these diseases,Insulin, as the nerve growth factor in a brain, can activate the propagation of dendron regeneration and stem cell, the growth that this is importantThe infringement of factor signal can cause dull-witted generation. Research find, in brain endogenous insulin can with its receptors bind, protectProtect the neuron under oxidative stress status, inhibited apoptosis, promotes cell repair, promotes that neuron proliferation and nerve cell are longThe projection making new advances, has obvious neuroprotection, and then affects brain activity and cognitive function and memory capability. But traditionalWhen insulin lumbar injection, insulin is difficult to see through blood-brain barrier, and the neuroprotection of insulin can not well be brought into play.

How insulin is by intravenous drip or hypodermic injection administration at present. Intravenous drip enters to be applicable to partial hospitalization patient, therefore pancreas isletThe hypodermic injection application of element is more extensive. But hypodermic injection insulin problem is many: the first, local lesion. InsulinLong-term subcutaneous injection, physics or chemical irritation can cause local organization blood circulation disorder, and local swelling, scleroma form, shadowThe absorption that rings insulin, further causes hypodermis degenerative atrophy, even occurs necrosis producing dysfunction. The second, senseDye. Diabetic organizes sugar content high, thereby is beneficial to the breeding of bacterium, and patient, if do not noted skin health, does not note when injectionMeaning sterile working, makes bacterium more easily invade body, and in addition, diabetic's resistance restoring force is all poor, makes to infect moreEasily further expand. The 3rd, pain. The about 2-4mm of human skin thickness, nerve endings is densely distributed, to stimulating sensitivity.Traditional subcutaneous injection method, is 30-40 degree angle with needle body and thrusts, and the length that syringe needle is walked in skin is greater than skin thickness,Larger to skin and nerve ending damage, and inserting needle speed is slow, and patient's feels pain is obvious.

Utility model content

There is the problem of local lesion, easy infection and pain in the utility model, a kind of pancreas is provided mainly for current insulin administrationIsland element intranasal medicator.

The utility model is to address the above problem the technical scheme of taking to be:

A kind of insulin intranasal medicator, comprises box body, wherein: the two cover syringes that be arranged in parallel in box body, every cover injectionDevice is all made up of needle tubing, liquid-dividing head, fixed block, propeller, leading screw, shaft coupling and stepper motor, and liquid-dividing head is positioned at needle tubingExit and and needle tubing communicate, the import of needle tubing is connected with fixed block, propeller be arranged on needle tubing interior and with one end of leading screwBe connected, the other end of leading screw is connected by the output shaft of shaft coupling and stepper motor through fixed block, is provided with step in box bodyEnter electric machine controller, the guidance panel of controllor for step-by-step motor is arranged on the bottom of box body, controllor for step-by-step motor and two steppingsMotor is connected, and two liquid-dividing heads are all connected with flexible pipe, and the outer end of flexible pipe extends to the outside of box body and connects a nose capsule,On nose capsule, offer fluid hole, being provided with power supply in the side of box body is stepper motor and controllor for step-by-step motor power supply.

The utility model adopts technique scheme, from nasal-cavity administration, is the abundant absorption of guaranteeing dose when administration, need to give againAfter medicine, rinse with physiological saline, therefore need two trocar tubes, the utility model utilizes two stepper motors to realize accurate administrationAnd flushing, when use, under the control of controllor for step-by-step motor, carry out, on guidance panel, set the amount of administration and flushingAmount, stepper motor can rinse completing after administration, then by be exactly nose capsule and flexible pipe be all soft, patient just can root like thisAccording to the sensation of oneself, nose capsule is fully filled in to nostril and carry out administration, therefore, compared with prior art, the utlity model has followingBeneficial effect:

The first, local excitation is little. By nasal-cavity administration, avoided hypodermic injection repeatedly to the stimulation of local organization cause damage andCause pain, simultaneously rich blood vessel in schneiderian membrane, has improved the bioavilability of insulin. The second, reduce infection. TraditionInjection of insulin before first need skin degerming, also need injection site rotation simultaneously, again should also be noted that and avoid reusingInjection needle. Ignore above any link and all can cause the incidence infecting to increase, by nasal-cavity administration, well reduced skinThe chance that skinfeel is dyed, has improved patient's compliance. The 3rd, not only can play blood sugar reducing function; Can also be without blood-brain barrier,Transport by olfactory nerve axoplasm, directly into encephalic, prevention and treatment are dull-witted. The 4th, can low dose of administration, accurately control and giveDose. The 5th, after administration, there is washing pipe device, ensure the release completely of medicine, reduce to greatest extent residual. The 6th, operation letterJust, can complete above-mentioned two processes by guidance panel. The 7th, device is light and handy, and portable, cost is low.
