Detailed description of the invention
Be described in further details with reference to accompanying drawing 1 to 6 pair of this utility model syringe embodiment.
A kind of syringe, comprise syringe needle 1, syringe 2, piston 3 and core bar 4, described syringe needle 1 outer surface is fixed with the first lucifuge layer 51, two end faces of described syringe 2 have been provided with the second lucifuge layer 52, the interlayer 6 around circumference is provided with in the sidewall of described syringe 2, the 3rd lucifuge layer 53 is provided with in described interlayer 6,3rd lucifuge layer 53 can be the cloth of black, described 3rd lucifuge layer 53 covers the side of syringe 2 completely, be provided with the rolling-up mechanism of rolling the 3rd lucifuge layer 53 in described interlayer 6, described syringe 2 is provided with the regulating part of adjustment the 3rd lucifuge layer 53 area coverage.
Described rolling-up mechanism comprises Scroll 71, described Scroll 71 is rotatably connected on interlayer 6 inwall, described 3rd lucifuge layer 53 side is fixed on Scroll 71, described Scroll 71 one end is provided with connecting axle 72, described connecting axle 72 one end and Scroll 71 are fixed, described connecting axle 72 other end passes from syringe 2, and described connecting axle 72 diameter is less than Scroll 71 diameter.
Described regulating part comprises slide block 81, described 3rd lucifuge layer 53 is fixed described syringe 2 outer surface away from the side of connecting axle 72 with slide block 81 and is provided with the annular groove 82 coordinated with slide block 81, described annular groove 82 is communicated with interlayer 6, and described syringe 2 outer surface is provided with the fixed mechanism of fixing slide block 81.
The area that 3rd lucifuge layer 53 covers syringe 2 sidewall can regulate, when the medicament running into injection can not be shown in light, slide block 81 can be stirred slide in annular groove 82, and then drive the 3rd lucifuge layer 53 mobile in interlayer 6, until the 3rd lucifuge layer 53 covers whole syringe 2 side, at this moment Scroll 71 is in the state of unreeling, and realized fixing by fixture block 9, such first lucifuge layer 51, second lucifuge layer 52 and the 3rd lucifuge layer 53 form good lucifuge structure, effectively avoiding the medicine component in syringe to see there is change in light, when injecting normal medicament at ordinary times, can by rotating Scroll 71, by the 3rd lucifuge layer 53 rolling on Scroll 71, sight line can not be stopped, increase visibility, convenient operation person better use, to sum up this syringe achieves the conversion between ordinary syringe and light-tight injector, and conversion operations is simple and convenient, so in use just without the need to preparing two kinds of different syringes in advance, diameter due to connecting axle 72 is less than the diameter of Scroll 71, Scroll 71 can be effectively avoided to deviate from from interlayer 6 like this.
Described fixed mechanism comprises fixture block 9, and described annular groove 82 inwall is provided with the holding tank 93 holding fixture block 9, and be provided with spring 92 between described fixture block 9 and holding tank 93 diapire, described slide block 81 is provided with the draw-in groove coordinated with fixture block 9.
Described fixture block 9 comprises Access Division 91, and described Access Division 91 is positioned at the side away from spring 92, and the both sides of described Access Division 91 are provided with intilted inclined plane 94, and the cross section of described Access Division 91 is trapezoidal.
When slide block 81 slide into the 3rd lucifuge layer 53 cover whole syringe 2 sidewall time, slide block 81 realizes fixing with coordinating of draw-in groove by fixture block 9, slide block 81 is in operation avoided to slide in annular groove 82 under self gravitation effect, the situation causing the 3rd lucifuge layer 53 well cannot cover syringe 2 sidewall occurs, the setting of inclined plane 94, fixture block 9 in slide block 81 sliding process is more easily coordinated with draw-in groove, because the power of slide block 81 pairs of fixture blocks 9 can be decomposed into the power that one is pointed to holding tank 93 inwall, and then spring 92 is compressed, at this moment fixture block 9 is received in holding tank 93, when fixture block 9 is in for position with draw-in groove, fixture block 9 can eject from holding tank 93 and realize fixing with draw-in groove clamping under spring 92 acts on.
Described connecting axle 72 end be positioned at outside syringe 2 is provided with Handheld Division 73.
The setting handled easily personnel of Handheld Division 73 are rotationally connected axle 72, and then facilitate Scroll 71 by the 3rd lucifuge layer 53 rolling, and wrapup procedure is more prone to laborsaving.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under this utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under this utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
