Abstract
The utility model discloses an anti-pollution addition injector, aiming at providing an injector with simple structure and easy access, comprising a syringe, wing plates arranged at both sides of the rear end of the syringe, a plunger in the syringe, a columnar push bar, one end of which is connected with the plunger, while the other end is linked to a pusher, a guide cap fixed on the swing plate at the rear of the syringe, as the columnar push bar being through the middle of the guide cap, an extensible pia-casing arranged at the outside of the columnar push bar between the guide cap and the pusher, and an air filter fixed near the swing plate at the rear of the syringe and communicated with the syringe bore. The utility model is applicable to human injection or chemicals preparation.
Description
Technical field
This utility model relates to a kind of syringe, refers in particular to a kind of anti-pollution injector that is used for human injection, dosing.
Background technology
At present, the medicine adding syringe that generally uses in the hospital is common syringe, is made up of syringe, piston and push rod, and medical personnel move by push rod push-and-pull piston when operation, realize operations such as aspiration medicinal liquid, admixing medical solutions.But find that in actual use medical personnel are when carrying out operation such as aspiration medicinal liquid, admixing medical solutions, finger can touch push rod, exist medicinal liquid contaminated may, cause cross infection easily.For avoiding medical personnel's pollution to medicinal liquid when using syringe, someone has proposed to increase the scheme of protection tube outside push rod, solve above-mentioned technical problem, but because of complex structure, manufacturing cost height, singlehanded use inconvenience are difficult to apply, thereby also do not have a kind of can being applied by effective antipollution syringe so far.
The utility model content
The technical problems to be solved in the utility model provides a kind of antipollution medicine adding syringe simple in structure, easy to use.
The technical solution of the utility model is such: a kind of antipollution medicine adding syringe, comprise syringe, be arranged on the wing plate on back end of syringe both sides, be arranged on the piston in the syringe, the column push rod that one end is connected with piston, the push pedal with the column push rod other end is connected is fixed with guide cover on the wing plate of wherein said back end of syringe, the column push rod passes this guide cover middle part, and the column push rod periphery between guide cover and push pedal is provided with telescopic mantle sleeve pipe; Being connected with air filter at the syringe rear portion near the wing plate place is communicated with the syringe inner chamber.
Syringe rear portion described in above-mentioned a kind of antipollution medicine adding syringe is provided with pipe joint near the wing plate place, and air filter is connected with pipe joint by flexible pipe.
After this utility model adopts said structure,, can reduce the external diameter of column push rod, make things convenient for medical worker's one hand to aspirate or the liquid medicine injection operation, compared with prior art have advantage simple in structure, easy to use owing to adopt the guide cover guiding.
Description of drawings
Below in conjunction with the embodiment in the accompanying drawing this utility model is described in further detail, but does not constitute any restriction of the present utility model.
Fig. 1 is the structural representation of a kind of specific embodiment of this utility model;
Fig. 2 is a practical view of the present utility model.
Among the figure: syringe 1, wing plate 1a, pipe joint 1b, piston 2, column push rod 3, push pedal 3a, guide cover 4, mantle sleeve pipe 5, air filter 6, flexible pipe 7.
The specific embodiment
Consult Fig. 1, shown in Figure 2, a kind of antipollution medicine adding syringe of the present utility model, comprise syringe 1, be arranged on the wing plate 1a on both sides, syringe 1 rear end, be arranged on the columniform column push rod 3 that piston 2, one ends in the syringe 1 are connected with piston 2, the push pedal 3a that is connected with column push rod 3 other ends, be fixed with guide cover 4 on the wing plate 1a of syringe 1 rear end, column push rod 3 passes this guide cover 4 middle parts, and column push rod 3 peripheries between guide cover 4 and push pedal 3a are provided with telescopic mantle sleeve pipe 5; Guide cover 4 and telescopic mantle sleeve pipe 5 are in conjunction with the inner chamber of column push rod 3 and syringe 1 can being isolated from the outside; Be connected with air filter 6 at syringe 1 rear portion near wing plate 1a place and be communicated with,, air filter 6 is connected with pipe joint 1b by flexible pipe 7 by near wing plate 1a place pipe joint 1b being set at syringe 1 rear portion with syringe 1 inner chamber.
When this utility model specifically uses, consult shown in Figure 2, medical personnel can be easily with the singlehanded push pedal 3a that spurs outside mantle sleeve pipe 4, drive column push rod 3 and move, move, can carry out operations such as aspiration medicinal liquid, admixing medical solutions, injection thereby drive piston 2 along guide cover 4, air filter 6 can be realized the air eliminating in the syringe 1 or suck simultaneously, make more convenient to operately, this utility model can effectively be avoided medical personnel's finger contact column push rod 3, prevents cross infection.
