Abstract
The utility model relates to a syringe belonging to medical instruments. The syringe is mainly composed of an outer cylinder and a central push bar. A mounting seat of a syringe needle is equipped at the front end of the outer cylinder. A plunger is connected at the front end of the central push bar. The plunger and the central push bar are equipped in the outer cylinder. The plunger is close matched with the inner wall of the outer cylinder. The central push bar is a hollow bar with a pore. Because the back end of the central push bar is conical, it is suitable to be held by a hand. The utility model provided with reasonable structure can decrease the pollution and be propitious to be matched with other medical equipment.
Description
Technical field
This utility model belongs to medical mechanical domain, relates in particular to a kind of injector for medical purpose that is used to inject transfusion.
Background technology
At present, syringe construction commonly used is simpler, mainly is made of urceolus and center push rod.Though this syringe widespread usage, center push rod is very easily contaminated, especially when medical personnel's one-handed performance, and easier touch center push rod rear portion and polluting.
Summary of the invention
The purpose of this utility model is to provide a kind of syringe rational in infrastructure, can eliminate artificial pollution, and can cooperate other instruments to use.
For achieving the above object, this utility model is taked following design: a kind of syringe, mainly constitute by urceolus, center push rod, outer cylinder front end has the syringe needle mount pad, front end in center push rod is associated with a piston, and piston and center push rod are installed in the urceolus, and piston and outer tube inner wall closely cooperate, center push rod is a hollow bar with holes, and the center push rod rear end is the taper that is suitable for holding.
The cross section in the hole of described center push rod can be circle or ellipse, triangle, rectangle, square, hexagon and octagon.
The utility model has the advantages that: can keep on the basis rational in infrastructure more cleaning, health, more reliable when patient is used, safety.
Description of drawings
Fig. 1 is the structure chart of the designed syringe of this utility model.
Fig. 2 is the A-A sectional view of the center push rod among Fig. 1.
Specific embodiment
The utility model is described in further detail in conjunction with specific embodiments with reference to the accompanying drawings below.
As shown in Figure 1, this utility model syringe mainly is made of urceolus 1, piston 2 and center push rod 3, urceolus 1 front end has syringe needle mount pad 4, piston 2 and center push rod 3 are installed in the urceolus 1, center push rod 3 is with holes 5 hollow bar, its front end is connected with piston 2, piston 2 closely cooperates with urceolus 1 inwall, center push rod 3 rear ends are taper, its cross sectional shape can be taked one of shape among as shown in Figure 2 B figure, C figure, D figure, E figure, the F figure as required, or is octagon and other polygonal shapes.
This syringe construction is reasonable, is convenient to operation, and is identical with the conventional injector use when using, but makes the center push rod part directly not contact with medicinal liquid owing to piston portion contacts with outer tube inner wall and medicinal liquid, therefore reduces the contact to medicinal liquid.The holding part and can limit the front end of hands sliding-contact center push rod forward of center push rod rear design, reduce the chance of polluting,, cleaning more much cleaner than conventional injector, and can cooperate with Other Instruments equipment by the hole 5 of center push rod 3, be easier to accurate control and the sterile working.
