Description
Technical field
This utility model relates to the semi-automatic subcutaneous injection of insulin device of a kind of medical semi-automatic syringe, particularly portable medical.
Background technology
The medical injection apparatus generally comprises traditional " pipe " formula and " pen " formula syringe etc., and building block comprises syringe needle, powder charge pipe, injection liquid pipe etc.The composition structure of this injecting apparatus determines its operation to comprise that manual syringe needle thrusts the difference process of human body, injection liquid and specific action image.
Use the diabetes patient of insulin injection treatment, majority must carry out 1 lifelong every day to injection for curing for several times, and this frequent injection for curing is generally undertaken by patient oneself.The time of injection, in 1 hour ante cibum, this period produced specific (special) requirements for the diabetes patient of frequent participation public activity to the volume of injecting apparatus, the aspects such as portability, privacy and health that operation produces by the treatment requirement.Most patient is because of the fear to traditional injection system, fears to do it yourself syringe needle thrust own health and refuses effectively that treatment causes the state of an illness to increase the weight of.Novel " pen " though the formula syringe does not have pain, hand syringes is thrust the action of own health like not being inconsistent with environment in public.
Insulin injection is still the most effective therapeutic modality of diabetes that can not be substituted at present, still do not have basic method of curing at present, so the diabetics fundamental need is taken medicine throughout one's life or insulin injection.Up-to-date theory of medicine is thought, diabetes patient's insulin injection early is expected to make islets of langerhans to have a rest and rehabilitation, with think that in the past early stage oral drugs stimulate islets of langerhans to recover, the reuse insulin is theoretical different when invalid, the popularization for the treatment of practical experience and new theory will strengthen the improvement demand to the insulin injection therapeutic modality.
Insulin injection needs high accuracy.The physiological need amount of common people's insulin is 24-30 unit's every day, treats injection volume between 5-20 unit at every turn, and the adjustment required precision reaches 1 unit.Insulin powder charge standard is generally at every milliliter of medicinal liquid insulin-containing 10 units at present, and the required precision of promptly harmonizing reaches more than 0.1 milliliter.
The adjustment precision of certain novel " pen " formula syringe has been higher than conventional syringe, but certainly lead to fluid loss at air-out with when extracting syringe needle, particularly when using the new clothes medicine bottle, can only after syringe needle is extracted human body, could discharge the medicine bottle applied pressure during injection, so per injection loses 1 at least---2 drops physic liquors.Every drops physic liquor insulin 2 units, i.e. per injection need be lost insulin 2---4 units, injection metering existing problems not only, expenses for medicine also is a major issue.My " pen " formula syringe of using for example, 3 total amount 30 units of insulin injection every day, average each loss Insulin 3 unit, daily loss insulin 9 units, monthly loss insulin 274 units, year loss Insulin 3,285 units, every bottled medicine 300 units promptly lose and amount to 11 bottles, by 57 yuan/bottle of market price RMB, 627 yuan of year loss RMB account for 23% of annual cost.
Report that diabetes patient all over China accounts for 2% of local population---4.6%, reached 2,400 ten thousand people at present, be 240,000 people as calculating use insulin injection number by 1%, annual medicinal liquid loss because of injecting apparatus will reach 1.6 hundred million yuan.According to World Health Organization (WHO) estimation, Chinese diabetes patient 100,000,000 people nearly after 15 years, no matter because of theory of medicine increases other factors such as using the insulin injection number, per 1% number (1,000,000 people) will reach 6.5 hundred million yuan because of the loss in direct year that injecting apparatus causes.
The utility model content
Purpose is to provide a kind of medical semi-automatic syringe, and this syringe is easy to carry, can accurately control injected dose, and not waste medicinal liquid, and safe and reliable, user is injection operation voluntarily.
For achieving the above object, technical solution of the present utility model is:
A kind of medical semi-automatic syringe comprises the syringe lid, syringe body, and injection needle also comprises drug storage bottle, injection bottle and spring injection link gear in the described syringe, the threeway by one-way cock between drug storage bottle and the injection bottle connects; Described spring injection link gear is included as that the injection bar provides the main spring of the power of opening and for the injection bar provides the injection spring of resilience force, the injection bar connects main spring and injection spring respectively.
Also comprise the injection latch mechanism in the described syringe, in the described injection latch mechanism injection spring is housed, be connected with arrangement of clutch.
Be provided with the threeway of one-way cock between described injection needle and the injection bottle.
Described injection bottle is provided with observation port, the injection key, and the dose indicator, the drug storage bottle is provided with observation port, and injection amount turn-knob connects injection bar and injection amount indicator.
Described syringe lid includes ethanol lid, ethanol box and ethanol box plug; Described ethanol lid has crotch, covers on the ethanol box.
Injector to inject work process of the present invention is: each relaxing of spring, needle tip place in the ethanol box, rotation injection amount knob and injection key.Take off the syringe lid, promote injection amount knob, through link gear pulling injection bar and injection plug by the sign direction, make the injection bottle produce negative pressure, medicinal liquid sucks the injection bottle from the drug storage bottle through one-way cock, and the individual event valve closing of syringe needle direction stops air admission simultaneously.The first end of entry needle is labelled to the human body position of intending injection, presses injection key release main spring, promote sliding seat.Simultaneously, injection bar and notes latch mechanism walk to front end release injection spring, promote injection bar and injecting glue plug, and the medicinal liquid in the injection bottle flows out from the syringe needle direction, injects skin.
After adopting such scheme, a kind of medical semi-automatic syringe of the present invention, the effect of bringing has:
1, because the present invention finishes syringe needle with mechanical action and thrusts skin, quick and precisely eliminates pain, be of value to diabetics and accept the most effective therapeutic modality because of mechanical action.
2, this syringe volume is little in light weight, is easy to carry, and is adapted at various environment and uses.
3, this syringe adopts precision optical machinery parts and significantly dose indication, can accurately set injected dose.
4, this syringe drug storage bottle and injection bottle separated structures are reduced to a minimum the medicinal liquid loss.
