Description
First, technical field
It the utility model is related to medical syringe technical field of structures, the particularly syringe for solid implant.Should
Implant syringe is can either be as the pre-filled container of solid implant, and having again can facilitate, directly solid is implanted into
A special injection device.
2nd, background technology
Implant has formulation with broad prospects for development as a kind of, available for antineoplastic, insulin administration, angiocarpy
The treatment of disease, ophthalmic administration and anti-additive etc..Because underlying nerve is distributed less, plant small to external foreign body reaction
Stimulation and pain after entering is relatively low, and patient satisfaction is high, strong adaptability.
3rd, the content of the invention
The utility model purpose is to provide a kind of disposable solid implant syringe,
The utility model solid implant syringe is by boosting lever apparatus (1), syringe body (2), syringe needle (3), needle cap
(4) form, such as Fig. 1,2,3,4.
Wherein：
1. boosting shank diameter is more than the internal diameter of syringe body top half, is advantageous to it and fixes without falling off；Boosting
The annex of bar and the handle of syringe body are interlocked, and help to prevent boosting bar free-falling from, to syringe bottom, playing fixation
The effect of boosting bar.
Boosting lever apparatus (1) is collectively constituted by pressing handle (1-1), push rod (1-2), annex (1-3), and it carries one
Annex (1-3), annex ability length range are 71.2mm ∽ 77.1mm, a diameter of 1.0mm~2mm, and annex bottom (near-end) is set
There are a ledge (1-4), a length of a width of 4mm of 6mm, a height of 2mm cuboid, as the fixed dress for preventing boosting bar from coming off
Put, can be matched with the lock pin on syringe body top.Push rod (1-2) length range of boosting bar be 108.6mm~
119.6mm, a diameter of 1.0mm~1.1mm, the proximal part of boosting lever apparatus have a push section (1-5), positioned at from near-end
At 0.4mm~0.5mm distally, diameter range is 0.95mm~1.0mm, to facilitate in its pre- threading syringe body,
And then it is set to fix coming off without freely falling body.The handle (1-1) of boosting bar is a cuboid, and length is respectively

Under the background that scientific and technological progress, medical science and pharmaceutical formulations continue to develop, the solid implant that the utility model is related to
Syringe just has suitable practical value and application prospect.The utility model can be added using in general medical engineering plastics
Work, so the main composition material of this solid implant syringe can be benzene polyethylene and/or its copolymer, polyether sulfone, poly- third
The plastics etc. of alkene or copolyester, other medical copolymer materials, because the difference of thickness be present in its each several part internal diameter,
Can produce certain frictional force during use, thus the material of the solid implant syringe should have it is certain it is expansible, can
The elasticity of contraction, rather than pure hard material, to facilitate processing, preparation and use.The utility model can facilitate, directly will
Solid implant is implanted in that patient is subcutaneous, and can be as the storage container of the solid implant.Face shaping and normal injection
Device is similar, but internal structure has significant difference, difference.(whole syringe and its each part are divided into near-end
And distal end, upper end is distal portions, and lower end is proximal part.)
Embodiment：
As shown in Figure 1,2,3, 4, the utility model is provided with the boosting bar 1 with annex, the injection that usual syringe has
Body 2, syringe needle 3, needle cap 4, the near-end of syringe body 2 is provided with storage medicine cavity 2-5.The ledge 1-3 of the annex of boosting bar 1
It can be interlocked with the lock pin 2-2 of syringe body 2, the push rod 1-2 of boosting bar is inserted into the left side of syringe body 1/3rd
The right side, to play a part of fixed boosting bar jointly, while it is also possible to prevent to carry the solid implant in medicine cavity from syringe body
Distal end comes off；Also, the lock pin 2-2 of syringe body 2 is arranged to two sides opening, departs from and lock to prevent the annex of boosting bar from loosening
Sell 2-2.Therefore, can be operated on the canned production line of solid implant from distal end to near-end, i.e. boosting bar-syringe
Body-solid implant-syringe needle-needle cap-packaging., may because each several part connection and internal diameter the problem of having differences be present
Larger frictional force can be produced, the plastics of very hard fracture, it requires this solid implant syringe syringe body 2,
The hourglass neck 3-2 and pintle 3-3 of syringe needle 3, the material of needle cap should have certain elastoplast, such as conventional medical injection equipment
The polystyrene of matter, polypropylene, makrolon, copolyester etc..The medical stainless steel pin that pin stalk 3-4, needle point 3-5 are integrated.
The material of boosting bar can be any one in above-mentioned material.
When in use, needle cap 4 need to be pulled out first, the needle point 3-4 of syringe needle 3 is pierced into patient's hypodermis；Then again will
Boosting bar 1 rotates to an angle, and makes the ledge 1-3 of annex and the lock pin 2-2 of syringe body 2 of boosting bar 1 being interlocked
Separation, then the finger press handle 1-1 of boosting bar 1 is promoted, the push rod 1-2 of boosting bar 1 is promoted forward, and then syringe body 2
In storage medicine cavity promote 2-5 in solid implant enter syringe needle 3 after, the needle tubing 3-4 through syringe needle 3 enters subcutaneous group of patient
Knit, so as to complete the solid implant implantation subcutaneous process of patient.Use state figure is as shown in figure 26.
