The utility model provides a disposable medicine pushing device which comprises a syringe barrel and a piston rod arranged in the syringe barrel in a sliding manner, wherein elastic pieces are symmetrically arranged on two sides of the piston rod, one end of each elastic piece, which is far away from the head of the syringe barrel, is outwards tilted, an arc-shaped limiting piece is arranged on the piston rod, a groove is formed in the arc-shaped limiting piece, corresponding to the elastic piece, and when the piston rod is inserted into the innermost position of the syringe barrel, the arc-shaped limiting piece is abutted with the syringe barrel.
As a further improvement of the scheme, one side of the arc-shaped limiting piece, which is close to the injector cylinder body, is vertically extended to be provided with a limiting baffle.
As a further improvement of the scheme, wing plates are symmetrically arranged on two sides of the arc-shaped limiting piece.
As a further improvement of the above solution, the head of the syringe barrel is connected with a catheter through a two-way connection.
As a further improvement of the scheme, the injector further comprises a mounting plate and a sliding seat arranged on the mounting plate in a sliding manner, wherein the piston rod is driven by the sliding seat to be inserted into the syringe barrel, and the sliding seat is driven by the driving mechanism.
As a further improvement of the above scheme, the driving mechanism is composed of a driving motor and a screw rod, and the sliding seat is arranged on the screw rod through thread transmission.
As a further improvement of the scheme, the end part of the piston rod is provided with a limit bar, and the sliding seat is provided with a limit groove corresponding to the limit bar.
The beneficial effects of the utility model are as follows:
compared with the prior art, the disposable medicine pushing device provided by the utility model has the advantages that when the disposable medicine pushing device is used, medicine liquid is firstly pumped into the syringe barrel, and because the repeated drawing is needed in the process of pumping the medicine liquid, the air in the syringe barrel is discharged, and the medicine liquid is sucked, the arc-shaped limiting piece is arranged on the piston rod, so that when the piston rod is prevented from being pushed inwards, the piston rod is prevented from being pushed to the bottom, and then the disposable buckle device (the elastic sheet is clamped in the syringe barrel) is triggered. When the inside of the syringe barrel is pumped to the preset liquid medicine, when the liquid medicine in the syringe barrel is extruded and discharged, the piston rod is pushed to the bottom, the elastic sheet is clamped in the syringe barrel, and as the elastic sheet is arranged to protrude out of the surface of the piston rod, the piston rod cannot be pulled out even if the piston rod of the syringe is pulled back, so that the syringe is prevented from being used for the second time and pollution is caused. The utility model provides a disposable medicine pushing device which can enable a syringe to be disposable and avoid infectious diseases.
