Abstract
The invention relates to a bidirectional injector, which is characterized in that two push-pull holes are formed in a needle-tubing round flanging at a port of a needle tubing body, the needle tubing body is further sleeved with a movable disc and is inserted into a central round hole of the movable disc, the movable disc is sleeved on the needle tubing body in a back-and-forth moving manner and is provided with two groups of connecting chucks corresponding to the push-pull holes, two push-pull rods are parallel to a core rod and are connected with the core rod through a push-pull handle, the core rod is communicated with a rubber piston on the core rod and is arranged in the needle tubing body, and the push-pull rod penetrates through the push-pull holes and then is connected with the movable disc in a manner that the connecting chucks on the movable disc are inserted into connecting holes in the push-pull rod in a fastening connection way. The bidirectional injector has the beneficial effects that a better labor-saving performance is achieved for sampling with one hand in a narrow environment during operation, and the injector can be fully sucked with liquid and is rapider during one-hand operation when the injector is used for sucking the liquid.
Description
Technical field
The present invention relates to a kind of two-way syringe, belong to medicine equipment, be used for adopting when one hand is taken a sample in narrow and small environment with syringe because of the chemical examination needs.
Background technology
At present, need draw syringe core rod to pull outward with finger more than two when having syringe sampling now, other finger also will be held syringe, and one-handed performance is inconvenience very.
Summary of the invention
Technical matters to be solved by this invention is the deficiency that overcomes prior art, and a kind of two-way syringe is provided, and invention solves the technical scheme that its technical matters adopted and is: structure of the present invention comprises pull bar, connecting hole, mobile disk, connection dop, core bar, rubber piston, push-pull handle, needle tubing body, the circular flange of needle tubing, push-and-pull hole; The circular flange of needle tubing that it is characterized in that needle tubing body port is provided with two push-and-pull holes; The needle tubing body also is inserted in and is provided with a mobile disk, and the needle tubing body inserts and is arranged in the center hole that moves disk, and mobile disk can be enclosed within the needle tubing body and move forward and backward; With also be provided with two groups on the mobile disk of the vertical correspondence position in push-and-pull hole and be connected dop; Two groups of pull bars and core bar are arranged side by side, and two groups of pull bars and core bar link together through push-pull handle, and the rubber piston that core bar is communicated with on the core bar is arranged in the needle tubing body; Pull bar is connected with mobile disk after passing the push-and-pull hole; Pull bar is fastenedly connected for the connecting hole that is connected in the dop insertion pull bar that moves on the disk with the connected mode of mobile disk, and thumb is pinned the circular flange of needle tubing, and forefinger and middle finger are pinned mobile disk; Mobile disk is moved to the circular flange direction of needle tubing along the needle tubing body; Outwards spur core bar through pull bar, push-pull handle and accomplish the imbitition action, thumb is pinned push-pull handle, and forefinger and middle finger are pinned the circular flange of needle tubing; Push-pull handle is moved to the circular flange direction of needle tubing, inwardly promote core bar through pull bar, push-pull handle and accomplish the injecting fluid action.
The invention has the beneficial effects as follows, when being convenient in narrow and small environment singlehanded sampling operation more laborsaving, one hand is held the syringe mode and is more unfolded; Finger is difficult for blocking sight line without curved transitions, is more convenient for observing; Can once syringe be filled when being convenient to the time one-handed performance with the syringe imbitition, faster.
