Embodiment
The present invention will be further described in detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1, 2, this PTFE syringes, including the cylinder 1 being made up of PTFE material, one end of cylinder 1 are provided with syringe needle
Mounting seat 2, the push rod 3 that can extend into the medicament chamber of cylinder 1 is provided with the other end of cylinder 1, provided with pre- storage between push rod 3 and cylinder 1
Medicament structure, cylinder 1 is located at one end outer part of push rod 3 and is provided with the first ear body 11, and the outer end of push rod 3 is provided with the second ear body 31, pushed away
Spacing neck 32 is offered close on one end outer part of the second ear body 31 on bar 3, being provided between cylinder 1 and push rod 3 to prevent
Only syringe maloperation causes out the arc-shaped limit body 4 of liquid, and the inwall of arc-shaped limit body 4 and the outer wall of push rod 3 are adapted, arc-shaped limit
The convex body 41 of body 4 is fastened in spacing neck 32, and the two ends of arc-shaped limit body 4 are offered respectively can be with the first ear body 11 and second
The arc-shaped slot 42 that ear body 31 coordinates, is also arranged between arc-shaped limit body 4 and push rod 3 and easily tears ring 5.Syringe typically uses glass
Glass is made, or the disposable product being made using PE, PP material.Glass syringe can be reused after autoclave sterilization,
So handle insufficient risk for having germ cross-infection, and glassware it is frangible (including glassware without external force it is excessive or
Person's moment excessive temperature differentials is frangible).And the resistance to temperature value of syringe that common PE, PP material is made should not repeat to make below 110 DEG C
With easily causing white pollution, be unfavorable for environmental protection.I takes charge of the PTFE syringes of research and development, solves well above is product lacks
Point, and PTFE drug resistances are extremely strong, do not reacted with medicine.In application aspect, injected except being normally used for human body and animal
Outside, in the article required for directly can also injecting the strong liquid of the liquid or corrosivity of high-temperature or conduction oil.It is existing
Inoculated syringe is applied in clinic in increasing enterprise, pre- embedding injection is provided simultaneously with storage medicine or reagent,
Need using compatibility and the material having good stability, PTFE not only has good chemical-resistant resistance and relatively low broken danger
Danger, and do not reacted with medicine, the status of substitution ordinary syringe can be turned into from now on.
In particular, the cross section of arc-shaped limit body 4 is in minor arc shape；Ring 5 is easily torn provided with easily tearing ear 51；Pre- drug storage agent
Structure is provided with aperture diminishing cone from outside to inside including being arranged on inner drug storage blind hole 3a, the drug storage blind hole 3a the inners of push rod 3
Push away body 3c provided with the drug that can move in drug storage blind hole 3a in hole 3b, drug storage blind hole 3a, drug push away body 3c it is inner on set can
When drug pushes away the cone 3d coordinated when body 3c is moved to drug storage blind hole 3a the inners with taper hole 3b, drug, which pushes away to be additionally provided with body 3c, to be easy to
The medicine outlet hole 3e of puncture.
