Abstract
A self-destroying injector able to be used only once features that after the injector is used once, its piston is dissolved by liquid medicine. Its piston is prepare through mixing starch, magnesium stearate, arobic gum, hydroxypropyl cellulose, acrylic resin and disintegrant together, adding distilled water, stirring, granulating, and die pressing.
Description
Technical field:
The invention belongs to manufacture technology field of medical appliance, is a kind of syringe and preparation method thereof.
Background technology:
Injector for medical purpose mainly is made of needle tubing, syringe needle, push rod and piston body, is mainly used in subcutaneous injection, because syringe uses repeatedly and may produce cross infection, generally all adopts disposable syringe at present.And existing disposable syringe is to be processed with the frangibility gap on push rod, after the use, operator fracture push rod, to prevent repeated use, this kind method needs the repeated use of active protection syringe, because a variety of causes, as operator's push rod that in time do not fracture, or subjectively will reuse consciously, then can not reach disposable purpose.
Summary of the invention
The technical problem to be solved in the present invention provide after a kind of use can self-destruction disposable syringe.
The present invention provides the method for making this kind syringe simultaneously.
Technical scheme of dealing with problems of the present invention is to adopt a kind of piston body that material that water can self-dissolving is made syringe of meeting.
Piston body is made by following component material: (consumption is a ratio of weight and number)
Starch 50-70 magnesium stearate 0.5-1.5
Arabic gum 2-4 hydroxypropyl cellulose 10-20
The instant disintegrating agent 3-7 of acrylic resin 0.5-1.
The preferred weight portion rate of piston body material component is:
Starch 50-70 magnesium stearate 0.5-1.5
Arabic gum 2-4 hydroxypropyl cellulose 10-20
The instant disintegrating agent 3-7 of acrylic resin 0.5-1.
Manufacture method of the present invention is as follows:
Starch, magnesium stearate, arabic gum, hydroxypropyl cellulose, acrylic resin and instant disintegrating agent are dropped in the comminutor by above-mentioned ratio of weight and number; add the pelletize of distilled water batch mixing; the weight of distilled water is the 10-20% that above-mentioned raw materials mixes the back gross weight; drop in the mould again; at pressure is press forming under the 1.5-5 ton condition; make can self-dissolving piston body, last and needle tubing, syringe needle and push rod together are assembled into self-destruction syringe.
Syringe of the present invention, its piston body is a primary raw material by starch, and be furnished with magnesium stearate, arabic gum and acrylic resin, can reach the integrally curing synthetic effect, and has needed intensity, hydroxypropyl cellulose is a colloidal adhesive, can strengthen the vacuum effectiveness between piston body and the needle tubing, and instant disintegrating agent accelerating piston body is effectively met the water self-dissolving.
Syringe of the present invention meets medicinal liquid in operating process, with the self-dissolving of back piston body, can not reuse.
Syringe of the present invention can be avoided becoming artificial damage and being self-destruction to have strengthened reliability widely, health safe in utilization owing to reuse the cross infection that causes effectively.
Description of drawings:
Accompanying drawing is a syringe cutaway view of the present invention.
The specific embodiment:
Starch 60 grams, magnesium stearate 1 gram, arabic gum 2 grams, hydroxypropyl cellulose 15, acrylic resin 0.8 gram and instant disintegrating agent 5 grams are dropped in the comminutor; add distilled water 10 gram batch mixing pelletizes; drop in the mould again; at pressure is press forming under 3 tons of conditions; make can self-dissolving piston body 4, last and needle tubing 1, syringe needle 2 and push rod 3 together are assembled into self-destruction syringe.
Wherein different size syringe used pressure in piston body manufacturing process is as follows:
1-5 milliliter pressure is the 5.5-4.5 ton;
10-30 milliliter pressure is the 4-2.5 ton;
50 milliliters of pressure are 1.5 tons.
