Abstract
The utility model discloses a double needle tubes injector, which comprises a plunger, a liquid tube and a needle tube. The needle tube comprises a delivery tube and an exhaust tube. A plug valve is provided on the exhaust tube. The utility model saves labor in drawing and injecting, has rapid speed and improves the work efficiency.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially a kind of crosspointer pipe syringe.
Background technology
What hospital used now all is single needle pipe syringe, its inconvenience is made up a prescription very inconvenient exactly, and particularly pulverulent medicine will dissolve medicine, need to inject liquid, not only speed is slow, and effort, also is like this during medicine that outwards draw dissolved is good, sometimes dosage is bigger, annotate to the end that medicinal liquid advances not go, just need with transfusion and in air take out some after, could continue.
Summary of the invention
The purpose of this utility model is exactly that a kind of crosspointer pipe syringe of regulating pressure in the medicine bottle will be provided.
The purpose of this utility model is achieved in that a kind of crosspointer pipe syringe, comprises piston 1, liquid-holding pipe 2 and needle tubing 3, and needle tubing 3 is made up of catheter 4 and exhaustor 5, and exhaustor is provided with valve plug 6.
This utility model is owing to adopt said structure, and it is time saving and energy saving to make up a prescription, and is convenient to operation.
Description of drawings
Be described further below in conjunction with the drawings and specific embodiments.
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Structure of the present utility model is as shown in Figure 1: a kind of crosspointer pipe syringe, comprise piston 1, liquid-holding pipe 2 and needle tubing 3, and needle tubing 3 is made up of catheter 4 and exhaustor 5, and exhaustor is provided with valve plug 6.
Pulling piston 1 when extracting medicinal liquid, medicinal liquid enters in the liquid-holding pipe 2 through catheter 4, opens valve plug 6 simultaneously, and air enters medicine bottle through exhaustor 5, and pressure increases in the bottle, and is so just much laborsaving; Along with the injection of liquid, the pressure in the bottle increases, and at this moment opens valve plug 6 during injection, and air is just discharged from exhaustor 5, and the pressure in the bottle has just significantly reduced, and injection is also just easier.
