Abstract
Anti -contamination syringe belongs to the medical instrument field, pushes away handle, piston head, syringe needle, injection mouth, flange, flexible protective layer, moving casing and air vent including cylinder, piston push rod, piston, cylinder bottom is equipped with the injection mouth, and the cylinder upper end is equipped with the flange, and the syringe needle cup joints on the injection mouth, and piston head and cylinder inner wall interference fit, piston push away and be equipped with flexible protective layer between the flange of handle and cylinder, and flexible protective layer is cup jointed by the through moving casing of a plurality of and forms, with the piston push rod parcel wherein, it is fixed that the one end of flexible protective layer and piston push away the handle, the other end is fixed with the flange of cylinder, compared with the prior art, the utility model discloses can avoid finger touching piston push rod, the interior liquid medicine of prevent pollution cylinder.
Description
Technical field
This utility model belongs to medical instruments field, particularly relates to anti-pollution injector.
Background technology
Use disposable syringe the most clinically, although decrease the probability of cross infection, but extracting and injecting more
During liquid medicine, because syringe piston push rod exposes in atmosphere, from the point of view of the practical situation the most quickly made up a prescription, medical personnel
In actual mechanical process, piston push rod posterior segment is easily by finger pollution, with syringe contact internal walls during propelling medicine, thus dirty
Dye sterile liquid medicine, causes cross-patient contamination.
Summary of the invention
The technical problems to be solved in the utility model is to provide antipollution syringe.
For solving above-mentioned technical problem, the technical solution of the utility model is: anti-pollution injector, including syringe, piston
Push rod, piston push handle, piston head, syringe needle, injection nozzle, flange, flexible protective layer, moving casing and passage, at the bottom of described syringe
Portion is provided with injection nozzle, and its upper end is provided with flange, and pinhead sleeve is connected in injection nozzle, piston head and syringe inwall interference fit, lives
Being provided with flexible protective layer between plug push handle and the flange of syringe, flexible protective layer is by the socket of several through moving casings
Becoming, wrapped up wherein by piston push rod, one end of flexible protective layer is fixed with piston push handle, and the flange of the other end and syringe is fixed.
Described flexible protective layer is provided with at least one passage in the one end near flange.
Described flexible protective layer uses soft transparent plastics to make.
Compared with prior art, this utility model simple in construction, easy to use, it is possible to effectively to prevent liquid medicine from suffering antibacterial
Deng foreign substance pollution.
Accompanying drawing explanation
Fig. 1 is that this utility model anti-pollution injector stretches protective layer extended configuration schematic diagram；
Fig. 2 is that this utility model anti-pollution injector stretches protective layer contraction state schematic diagram；
In figure: 1, syringe 2, piston push rod 3, piston push handle 4, piston head 5, syringe needle 6, injection nozzle 7, flange 8,
Flexible protective layer 9, moving casing 10, passage.
Detailed description of the invention
The utility model is described in more detail with detailed description of the invention below in conjunction with the accompanying drawings.
Anti-pollution injector, including syringe 1, piston push rod 2, piston push handle 3, piston head 4, syringe needle 5, injection nozzle 6, flange
7, flexible protective layer 8, moving casing 9 and passage 10, be provided with injection nozzle 6 bottom described syringe 1, and syringe 1 upper end is provided with flange
7, syringe needle 5 is socketed in injection nozzle 6, and piston head 4 and syringe 1 inwall interference fit, between the flange 7 of piston push handle 3 and syringe 1
Being provided with flexible protective layer 8, flexible protective layer 8, according to Telescopic cup principle, is socketed to form by several through moving casings 9, will
Piston push rod 2 wraps up wherein, and one end of flexible protective layer 8 is fixed with piston push handle 3, and the other end is fixing with the flange 7 of syringe 1.
Described flange 7 and piston push handle 3 are oval, and flexible protective layer 8 is less than near moving casing 9 diameter of flange 7
The width of flange 7, moving casing 9 diameter near piston push handle 3 is less than the width of piston push handle 3, and flexible protective layer 8 is extensible
Greatest length more than piston push rod 2 range of 1 in syringe, single-unit activity sleeve pipe 9 when flexible protective layer 8 shrinks completely
Length less than the beeline of flange 7 with piston push handle 3；During extraction liquid medicine, forefinger, middle finger and thumb cooperation pull out work
Plug push handle 3, flexible protective layer 8 extends back therewith, otherwise, when injecting liquid medicine, flexible protective layer 8 is to contract；In this process
In, piston push rod 2 is isolated by flexible protective layer 8 all the time with finger, thus avoids the finger of operator to connect with piston push rod 2
Touch, play the effect preventing liquid medicine from suffering the foreign substance pollutions such as antibacterial；Flexible protective layer 8 uses soft transparent plastics to make, and is leaning on
One end of nearly flange 7 is provided with at least one passage 10, convenient use.
