Abstract
The invention belongs to the field of medical apparatuses and particularly relates to a syringe with an inner blocking plug. The syringe with the inner blocking plug is characterized in that a solid push rod is mounted in a sleeve, the inner blocking plug is mounted on a fixing ring which is arranged at the front end of the solid push rod, a piston is mounted on the inner blocking plug, and a guide sleeve is mounted at the tail end of the solid push rod. In conclusion, owing to the guide sleeve mounted on the sleeve, the cross section of the solid push rod can be made pretty small, and accordingly raw materials can be greatly saved; owing to the inner blocking plug mounted on the fixing ring, stability and reliability in operation of the piston in the sleeve can be guaranteed.
Description
Technical field
the invention belongs to medical apparatus field, specifically relate to a kind of syringe with internal congestion.
Background technology
the core bar of the syringe using clinically at present, ubiquity the raw-material structural design of waste, because the syringe using is clinically disposable, so waste suitable surprising, medical personnel are in the time inhaling medicine and injection operation, also effort relatively of syringe core rod push-and-pull, and hands is easily from the landing of overcoat edge, thus cause the generation of malpractice.
Summary of the invention
object of the present invention, is just to overcome above-mentioned shortcoming, and a kind of syringe with internal congestion providing.
the present invention is achieved in that a kind of syringe with internal congestion, it is characterized in that: in the inside of sleeve, solid push rod is installed, front end at solid push rod is processed with retainer ring, internal congestion is installed on retainer ring, piston is installed on internal congestion, at the end of solid push rod, fairlead is installed.
Brief description of the drawings
below in conjunction with accompanying drawing, the present invention will be further described in detail.
fig. 1 is main cutaway view of the present invention.
fig. 2 is Fig. 1 " A-A " cutaway view.
fig. 3 is Fig. 1 " B-B " cutaway view.
fig. 4 is Fig. 1 " C-C " cutaway view.
in figure, each label declaration is as follows:
1, sleeve, 2, piston, 3, internal congestion, 4, retainer ring, 5, solid push rod, 6, fairlead, 7, pusher grip.
Detailed description of the invention
sleeve 1 of the present invention is selected the time processing molding in mould of PP polypropylene material, the effect of sleeve 1 is store medicinal liquid and piston 2 is slided in sleeve 1, piston 2 is selected the time processing molding in mould of butyl rubber material, the effect of piston 2 is exactly by the thrust of solid push rod 5, the medicinal liquid of sleeve 1 interior storage is passed through to syringe needle, in patient body, inject, or the medicinal liquid of sleeve 1 interior storage is carried out to other operation etc. by syringe needle, internal congestion 3 is selected the time processing molding in mould of PP polypropylene material, its effect is exactly fixed piston 2, ensure that piston 2 working stabilities are reliable, retainer ring 4 is selected the time processing molding in mould of PP polypropylene material, its effect is exactly to ensure that pin head 3 piston 2 working stabilities are above reliable, solid push rod 5 is selected the time processing molding in mould of PP polypropylene material, its effect is exactly to ensure that retainer ring is reliable at the interior working stability of sleeve 1, fairlead 6 is selected the time processing molding in mould of PP polypropylene material, its effect is exactly that solid push rod 5 is easy to operate reliable and stable while injecting, core bar pushes away handle 7 and selects the time processing molding in mould of PP polypropylene material, its effect is exactly while working, ensure that piston 2 working stabilities are reliable.
in sum, the present invention owing to being provided with fairlead 6 on sleeve 1, and the cross section of solid like this push rod 5 is processed into very little, can greatly save like this raw material, due to internal congestion 3 being installed on retainer ring, can ensure that the working stability of piston 2 in sleeve 1 is reliable simultaneously.
