State the propulsion plant of piston rod back and forth movement, the medicine outlet of the drug storage pipe is connected with drug branch pipe, the drug branch pipe with
Drug main pipe connects.
Wherein, the propulsion plant includes screw mandrel, screw rod bracket, the screw along the screw mandrel back and forth movement and is used for
Drive the drive device of the screw mandrel rotation.
Wherein, the propulsion plant also includes the spring being set on the screw mandrel between the screw and screw rod bracket.
Wherein, the push rod for driving the piston rod back and forth movement is provided with the screw.
Wherein, also including the electric control gear for controlling the drive device work.
Wherein, the side of the medicine outlet of the drug storage pipe is provided with the feeding opening for feeding liquid, on the feeding opening
Be provided with and enter medicine branch pipe for enter medicine, it is described enter medicine branch pipe connected with medicine main pipe is entered.
Beneficial effects of the present invention：The present invention includes medicine box, and several syringe pumps being engaged with the medicine box, institute
State and be evenly equipped with medicine box several drug storage pipes, the syringe pump includes the piston rod for being engaged with the drug storage pipe, and
Propulsion plant for driving the piston rod back and forth movement, the medicine outlet of the drug storage pipe is connected with drug branch pipe, described
Drug branch pipe connects with drug main pipe., can be distributed to the liquid of certain volume in multiple drug storage pipes by the setting of medicine box,
And then it is easy to extend the total length of drug storage pipe such that it is able to the propulsion precision of fixed volume liquid unit injection volume is effectively reduced,
Finally play the purpose for reducing propulsion plant production cost, the present invention, Neng Gouyou relatively low to the propulsion required precision of propulsion plant
Effect reduces the production cost of injection device.
Brief description of the drawings
