Description
Technical field
This utility model relates to a kind of syringe, more specifically to a kind of syringe that accurately measures medicinal liquid.
Background technology
In medical industry, syringe uses more frequent, common syringe adopts transparent material to make, syringe side is provided with scale, but for some old peoples or people that some have defective vision, in the time using syringe to measure medicinal liquid, it is not very accurate often scale being held, some medicinal liquid is more or a little lessly may have larger impact to the person, so need at present a kind ofly can stablize the syringe that measures accurately medicinal liquid.
Summary of the invention
Order of the present utility model provides a kind of syringe that can accurate stable measures medicinal liquid.For achieving the above object, this utility model has adopted following technical scheme:
A kind of syringe, comprises syringe urceolus, piston, measuring stick, and described syringe urceolus bottom arranges syringe needle connector, and syringe urceolus upper end is provided with cocked bead; Described piston comprises piston lever, piston push rod and piston head, and piston is arranged in syringe urceolus; Described measuring stick is arranged to concave groove type, horizontal cross-section is semicircle, measuring stick bottom is provided with U-shaped draw-in groove, the cocked bead of syringe urceolus may be stuck in draw-in groove, measuring stick groove two edges are provided with several bayonet sockets, a metered body is installed in groove, and metered body can be by being connected and being stuck in groove with the bayonet socket on groove both sides, and what the other correspondence of described bayonet socket arranged has scale.
Described metered body can move up and down or remove on measuring stick.
Described bayonet socket is uniformly distributed in measuring stick both sides.
Described syringe urceolus cocked bead diameter is less than or equal to the interior diameter of draw-in groove.
The utlity model has following advantage: can stablize and measure accurately medicinal liquid, device is simple, applied range.

Detailed description of the invention
With the drawings and specific embodiments, this utility model is described in further detail below.
As illustrated in fig. 1 and 2, a kind of syringe, comprise syringe urceolus 7, piston, measuring stick 1, described syringe urceolus 7 bottoms arrange syringe needle connector 9, connector can use also not connecting needle to measure medicinal liquid use as graduated cylinder to patient injection medicinal liquid by connecting needle, and syringe urceolus 7 upper ends are provided with cocked bead 11; Described piston comprises piston lever 4, piston push rod 6 and piston head 7, and piston head 7 employings have elastic material makes, and piston lever 4 is circular, and piston is arranged in syringe urceolus 7; Described measuring stick 1 is arranged to concave groove type, horizontal cross-section is semicircle, measuring stick 1 bottom is provided with U-shaped draw-in groove 5, the cocked bead 11 of syringe urceolus 1 may be stuck in draw-in groove 5, measuring stick 1 groove two edges are provided with several bayonet sockets 2, a metered body 3 is installed in groove, metered body 3 can be by being connected and being stuck in groove with the bayonet socket 2 on groove both sides, metered body 3 both sides are provided with metered body fixed chuck 10, metered body fixed chuck may be stuck on bayonet socket 2, what the described other correspondence of bayonet socket 2 arranged has scale, and scale value is corresponding with the volume markings of syringe.
Described metered body 3 can move up and down or remove on measuring stick.
Described bayonet socket 2 is uniformly distributed in measuring stick both sides.
Described syringe urceolus 7 cocked bead diameters are less than or equal to the interior diameter of draw-in groove.
When use, arrive predetermined scale position by movable metering body in advance, then mobile piston, piston stops in the time arriving metered body lower end, and the medicine volume now sucking in syringe equates with the volume of pre-set scale.
