Description
Technical field
The invention belongs to medical apparatus and instruments, specifically a kind of safety self-destructing syringe production method and equipment.
Background technology
Injection is a treatment means common in the medical procedure, and annual enforcement the in the whole world injected 12,000,000,000 person-times.Because multiple reason, make that wherein the quite injection of number of times is unsafe: illegal businessman reclaims used syringe as part, carry out simple cleaning treatment after, be back in the medical system and reuse, cause collective's cross infection disease; And for example problem such as needle stick injury also happens occasionally, and is troubling.According to World Health Organization's statistics, 800 to 1,600 ten thousand HBV cases, 200 to 5,000,000 HCV cases, 80,000 to 160,000 HIV cases take place because of dangerous injection every year in the whole world; Dangerous injection simultaneously also can take place as bacterial infections such as acute infectious disease such as malaria, abscess, germ property and other infection etc. countless.These infect case and have caused 1,300,000 avoidable direct deaths, cause the indirect human loss of 2,600 ten thousand examples, and the direct medical expense that is used to handle and treat reaches 4,300,000,000 yuans.So dangerous injection has greatest threat for human existence health, medical system burden and society's finance expenditure have greatly been caused simultaneously.Because the serious harm of dangerous injection has caused the great attention of national governments.The Chinese government has issued " using disposable medical consumptive use product management way " in 2000, strict regulations various places medical institutions must not reuse syringe cylinder.Self-destruction syringe is adopted in beginning neonate in 2003 vaccine injection comprehensively.At present, also will further popularize the use of safety self-destructing syringe in an all-round way.The company of the safety self-destructing syringe that our times is well-known has: U.S. RetractableTechnologylnc company, Britain Scotland New Medical Technologrlnc company, European Safe Gard Medical company etc., but because the safety self-destruction syringe complex structure of its production, involve great expense, promote difficulty.Now the state-of-the-art method of production safety self-destruction syringe is that push rod front portion with syringe adds a steel crotch pin in the world, after syringe is finished using, draw back push rod, in the injection looper withdrawal syringe, form 45 degree lateral bendings, again can not release needle point, form self-destroying function, can not stab the operator again.This injector designed rationally, low cost, easy to use, easy popularization.Existing technology is with steel wire heating, operates in by hand on the injector push-rod steel crotch pin is installed, and causes quality instability, production efficiency low, can't realize large-scale production, can't satisfy social needs.Through extensively retrieving domestic and international publication and patent document, there is no the safety self-destructing syringe production method of production efficiency height, constant product quality and the report of equipment.So invent a kind of steady quality, production efficiency height, can realize the safety self-destructing syringe production method of large-scale production and very urgent, the important task that equipment is current international medical device industry.
Summary of the invention
The purpose of this invention is to provide a kind of steady quality, production efficiency height, can realize the safety self-destructing syringe production method and the equipment of large-scale production.
The object of the present invention is achieved like this:
The safety self-destructing syringe production method comprises the steps:
(1) injector push-rod is fixed on the anchor clamps on the automatic turntable;
(2) the air pump rifle pours steel wire in the head locating hole of push rod;
(3) cutter cuts off steel wire and with the steel wire bending;
(4) turntable drives the anchor clamps rotation automatically, changes injector push-rod, and the air pump rifle pours steel wire the push rod head once more, cuts off and crooked steel wire, and circulation is carried out repeatedly.
The safety self-destructing syringe production equipment is made up of anchor clamps, automatic turntable, accompanies injector push-rod in the anchor clamps; The top of injector push-rod is provided with locating hole; Cutter has been located in the front portion of injector push-rod; The rear portion of anchor clamps is provided with the air pump rifle, and the tail end of air pump rifle links to each other with cylinder; The top of air pump rifle is provided with the steel wire box, in the steel wire box steel wire is housed.
Locating hole matches with gauge of wire.
The main points of the inventive method are: use the air pump rifle that steel wire is poured injector push-rod; Use cutter steel wire to be cut off and bending.The inventive method has changed originally inserts the technology of injector push-rod with steel wire heating, has overcome steel wire heating and has inserted and form the plastics focus; Steel wire is pressed with the hard insertion of overhead kick may make steel wire consider the shortcoming of the poor product quality that comes off to be worth doing.
The main points of present device are: with combination accessories such as turntable, anchor clamps, air pump rifle, cylinder, steel wire box, steel wire, cutteves, and determine each position component according to arts demand according to inventive method.
Note following item in the invention process: in the injector push-rod top design a little syringe needle locating hole is arranged, then push rod is fixed on the anchor clamps, anchor clamps rotate automatically.At the anchor clamps top, the air pump rifle box that the medical grade steel wire is housed of ining succession; Utilize the gases at high pressure of air pump to impact puncture, steel wire of every one rifle shooting is squeezed into the injector push-rod head, and steel wire promptly connects with plastic push-rod; Cut off steel wire and steel wire is curved 45 degree with cutter then, its fastness reaches the 25KP pulling force, meets the syringe standard-required.Cutter had both had the cut-out function, had two kinds of functions of crooked steel wire again.Also can push pedal be set in addition during enforcement, be used for steel wire is pushed away curved.The steel wire that the present invention uses is can be as the medical grade steel wire of syringe needle use.
Advantage of the present invention is:
1. technology is simple, and is easy to operate.
2. produce and carry out the output height continuously automatically.
3. good product quality is safe in utilization.
4. after product uses, draw back push rod, in the injection looper withdrawal syringe, form lateral bending, needle point can't be released, and syringe can't reuse, and has solved syringe effectively and has repeatedly used the hidden danger of bringing.
