Abstract
The utility model discloses a light-shading syringe which comprises a light-shading needle cylinder and an injection rod arranged in the light-shading needle cylinder. A first scale mark is arranged on one side of the outer portion of the light-shading needle cylinder, a scale mark rod which is arranged side by side with the injection rod is arranged on one side of the first scale mark, the injection rod and one end of the scale mark rod are connected to a handle of the injection rod, and the scale mark rod is located outside the light-shading needle cylinder. According to the light-shading syringe, the scale mark rod is increased, reading is more visual by directly reading scales which the mark rod points to, and the light-shading syringe is convenient to operate and easy to control. An existing light-shading syringe with a black needle cylinder enables the scales to be marked on the injection rod, accurate reading is difficult, accurate injection cannot be performed, and double-row scale marks enable the mark scales to be more accurate. The light-shading syringe can also serve as a microsyringe and be used for accurate micro-injection and can be used for scientific experiments.
Description
Technical field
This utility model relates to injection device, relates in particular to a kind of light-tight injector.
Background technology
In clinical application or research work, some medicines (as Nimotop, dexamethasone, water soluble vitamins, the neural tracer of fluorescence etc.) unstable chemcial property, chance light easily decomposition go bad and influence effect, need to lucifuge use when injection.Current light-tight injector device mostly is manual self-control, and making step is complicated, is difficult to standardization, is difficult for extensively promoting the use of.Meanwhile, the disposable light-tight injector on market mostly is the translucent syringe of sepia or black syringe, and the former can not accomplish complete lucifuge, and the latter's reading is more difficult, is difficult to control injected dose, more can not carry out accurate micro-injection.Dose observation instrument while having in addition a kind of lucifuge micro-injection apparatus-lucifuge, but this observation instrument is still individual making, and error is larger, can not accurately observe.The microsyringe using in experimental work is clear glass syringe, when injection lucifuge material, be everlasting after imbitition and with black lucifuge cloth or black gummed paper, hide syringe again, and with immobilization with adhesive tape, this light-shading apparatus can not be in imbitition process lucifuge, and overcover easily comes off, do not reach the effect of complete lucifuge.
Summary of the invention
For the shortcoming of prior art, the purpose of this utility model is to provide a kind of light-tight injector, makes to inject lucifuge liquid convenient, and reading is more accurate and visual, and injection volume is more accurate, and lucifuge is more complete.
To achieve these goals, the technical solution of the utility model is: a kind of light-tight injector, comprise lucifuge syringe and be arranged at the injection rod in described lucifuge syringe, at lucifuge syringe, be outside equipped with the first scale marker, a side and injection rod at described the first scale marker are set up in parallel scale marker bar, injection rod and scale marker Gan one end are all connected on the handle of injection rod, and described scale marker bar is positioned at outside lucifuge syringe.
Preferably, the direction moving along injection rod below described the first scale marker is provided with a sliding tray, and described scale marker bar is arranged in this sliding tray.
Preferably, described sliding tray and scale marker bar are " protruding " word shape.
Preferably, also comprise the second scale marker being arranged side by side with the first scale marker, the first scale marker is provided with Digital ID, and the least count of the second scale marker is 1/2nd of the first scale marker least count.
Preferably, described sliding tray is arranged between the first scale marker and the second scale marker.
Compared with prior art, this utility model has increased scale marker bar, by directly reading mark rod indication scale, make reading more directly perceived, more convenient to operate and easily control, and existing black syringe light-tight injector is marked in scale on injection rod, be difficult to pin-point reading, can not accurately inject, to make to identify scale more accurate for double scale marker in addition.This utility model, also applicable to microsyringe, carries out accurate micro-injection, can be used for scientific experiments.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is injection rod of the present utility model and scale marker bar structural representation.
Fig. 3 is the axial view of lucifuge syringe of the present utility model.
The specific embodiment
Refer to Fig. 1, Fig. 2 and Fig. 3, the light-tight injector of the present embodiment comprises injection rod 1 and the lucifuge syringe 2 being arranged in lucifuge syringe, at lucifuge syringe 2, be outside equipped with the first scale marker 3 and the second scale marker 6 side by side, the first scale marker 3 is provided with Digital ID, the least count of the second scale marker 6 is 1/2nd of the first scale marker 3 least counts, a side and injection rod at scale marker are set up in parallel scale marker bar 5, one end of injection rod 1 and scale marker bar 5 is all connected on the handle 4 of injection rod, this scale marker bar 5 is positioned at outside lucifuge syringe 2, between the first scale marker 3 and the second scale marker 6, be provided with a sliding tray 7, scale marker bar 5 is arranged in this sliding tray 7, sliding tray 7 and scale marker bar 5 are " protruding " word shape.
Lucifuge syringe of the present utility model is opaque syringe, can guarantee that the operating procedures such as draw solution, injection, reading complete under lucifuge comprehensively, thereby reduce to greatest extent time of exposure, reaches the most effective light-shading effect.This utility model has increased scale marker bar outward at the original injection rod of reservation, scale marker bar is in parallel with injection rod, and length is consistent, when injection rod moves, mark rod also moves thereupon, and scale marker, in opaque syringe outer wall, is identified to injection volume by reading scale shown in mark rod, make reading more directly perceived, more convenient to operate and easily control.Being arranged side by side of the first scale marker and the second scale marker, when can guarantee accuracy of reading, and scale is too not intensive, the first scale marker has concrete numeral and continues to use ordinary syringe scale, the second scale marker is the scale marker that there is no reference numbers, this row's scale is divided into two parts by the first scale marker minima, for example, full-scale reading is 10ul syringe, the least count of the first scale marker is 0.1ul, the reading of the second scale marker is 0.05ul so, has improved the degree of accuracy of reading, can carry out more accurate micro-injection.This utility model adopts " protruding " font sliding tray, can make scale marker bar only have the degree of freedom of injection direction, and be embedded in opaque needle cylinder wall, prevent that mark rod from deviating from tube wall, " protruding " font scale marker bar not only can be embedded in needle cylinder wall by self better, also mark rod and syringe scale can be remained in same level, facilitate reading.
This utility model can form unification and manufacture specification (as clinical conventional 5ml, 1ml equal-specification, 10ul, 1ul equal-specification that scientific experiments is conventional), produce in enormous quantities and make, also can adopt unlike material according to concrete purposes, disposable use can adopt plastic material, reuse materials such as can adopting rustless steel and make, environmental protection more, cost is cheaper.
Although this utility model discloses as above with preferred embodiment, the scope of not implementing in order to limit this utility model.The ordinary person of any this area, within not departing from the scope of utility model, does some improvement, and every equal improvement of doing according to this utility model, should be scope of the present utility model and contain.
