Abstract
The utility model provides a syringe which comprises a push rod, a liquid suction tube and a detachable injection head with a micropore. The syringe is characterized in that the detachable injection head with the micropore and the liquid suction tube are in a split mode. The injection head is installed on the liquid suction tube in a screw mode or a buckle mode. Contact portions of an injection tube and the injection head is thin plastic. When high-pressure liquid passes by, the contact portions of the injection tube and the injection head are tightly attached under the action of pressure. The size of the micropore is 150 micrometers. The detachable injection head is composed of a core rod integral injection molding connected multiple-ring layer plastic piston with a connected locking head. The connected locking head is composed of an anchor type symmetrical double-leaf elastic locking head, a locking head body portion and a symmetrical termination locking barb. Due to the fact that the structure of the syringe is further simplified, rejection rate of products is reduced, and production cost of rubber pistons and assembly is saved. Used syringes are classified into medical waste and can be recycled to produce reprocessed plastic, and therefore the syringe is a green environment-friendly product.
Description
Technical field
This utility model relates to a kind of syringe of reusing and sharing of can preventing, belongs to Dispoable medical consumptive material field.
Background technology
Traditional syringe is by rustless steel syringe needle injection human body, and the Stainless Steel syringe needle not only can cause injection pain, and can cause dermatorrhagia, has potential infection risk, for fear of the use safety injection of syringe needle, need to avoid recycling of syringe.
The rubber piston of syringe has elasticity, can effectively prevent gas leakage and the leakage of piston.But, adapt to the in enormous quantities of automatic assembling production line (machine) and produce fast, must arrange in order towards a direction by mixed and disorderly unordered rubber piston mouth, the plastics core bar could be inserted in the rubber piston.This just proposes extra requirement to the automatic assembling production line, thereby has increased the Design and manufacture cost.
Summary of the invention
For overcoming above-mentioned technical problem, this utility model provides a kind of reasonable in design, dismountable syringe of reusing and sharing of can preventing.
For realizing above-mentioned technical purpose, this utility model is realized by the following technical solutions: a kind of syringe, comprise a push rod, the imbibition cylinder is with the detachable injection head of micropore, it is characterized in that detachable injection head and imbibition cylinder with micropore are splits, injection head is installed on the imbibition cylinder in the mode of screw socket or buckle, injection tube and injection head contact site are thin plastics, when highly pressurised liquid through out-of-date, because the effect of pressure is close to injection tube and injection head contact portion, wherein the micropore magnitude range is 150 microns, detachable injection head is by forming with the multi-ring layer of the core bar integrated injection molding disjunctor of disjunctor elongated insertion part plastic piston, and the disjunctor elongated insertion part is by the symmetrical bilobate elastic locking of anchor formula head, elongated insertion part body and the symmetrical locking agnail that stops form.
Preferably, detachable injection head is comprised of the symmetrical bilobate elastic locking sheet on core bar integrated injection molding disjunctor multi-ring layer plastic piston and the piston round tray periphery.
The utlity model has following beneficial effect: by medical waste is classified, first will be with the metal needle excision of needle shield, carry out 100-150 ℃ of heat sterilization harmless treatment, then carry out the production of regenerated plastics, recycling plastics, make product reach the requirement of low-carbon (LC) and environmental protection, adopt the multi-ring layer of core bar integrated injection molding disjunctor plastic piston can save the production cost of making rubber piston, and make design and produce simpler, can further reduce the percent defective of syringe during assembling, reach requirement of producing fast in enormous quantities.
