Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

The measuring cylinder is characterized by being provided by figures 1 to 5, comprising an upper axial barrel 1 and a lower axial barrel 1, wherein a rotating shaft 2 is coaxially and rotatably connected in the barrel 1, a plurality of blades 3 uniformly distributed along the circumferential direction are arranged at the lower end of the rotating shaft 2, a needle cylinder 5 with a needle head at the front end and the rear end is arranged at the left side of the lower end of the barrel 1 through a liquid inlet pipe 4, a piston 6 is coaxially and slidably connected in the needle cylinder 5, the liquid inlet pipe 4 is positioned at the rear part of the front end surface of the piston 6, a one-way liquid outlet valve 7 with an opening far away from the needle cylinder 5 is arranged at the rear end of the needle cylinder 5, an upper axial measuring cylinder 8 is arranged at the upper end of the barrel 1, semicircular through holes 9 are respectively formed in the upper side wall and the lower side wall of the measuring cylinder 8, a cylindrical rod 10 is.

In order to drive the rotating shaft 2 to rotate, the upper end of the barrel 1 is provided with a square box 12 with a downward opening, an upper axial motor 13 and a lower axial motor 13 are arranged in the square box 12, and the output end of the motor 13 is coaxially and fixedly connected with the rotating shaft 2.

In order to facilitate the pulling of the piston 6, a pull rod 14 is arranged at the front end of the piston 6, and the front end of the pull rod 14 extends out of the needle cylinder 5 and is provided with a pull plate 15.

For better stirring effect, the outer peripheral surface of the rotating shaft 2 is provided with a spiral plate 16 positioned above the blades 3.

In order to prevent the needle from stabbing the medical staff, the rear end of the needle cylinder 5 is detachably connected with a needle cap 17.

In order to prevent the liquid in the syringe 5 from flowing back to the barrel 1, a one-way liquid inlet valve 18 with an opening facing the syringe 5 is arranged in the liquid inlet pipe 4.

The utility model discloses when using, at first set up through-hole 9 on the lateral wall on graduated flask 8 and be in the open mode, piston 6 is in the rear end of cylinder 5, because two semicircle boards 11 are 180 and arrange, so through-hole 9 on the lateral wall under graduated flask 8 is in the closed mode at this time, the liquid medicine that will mix is poured into graduated flask 8 through-hole 9 of upside, confirm the volume of liquid medicine according to the scale on graduated flask 8, then make semicircle board 11 of upside rotate 180 clockwise, through-hole 9 of upside is in the closed mode this moment, through-hole 9 of downside is in the open mode, the liquid medicine in graduated flask 8 gets into cask 1 through-hole 9 of downside in, then adopt above-mentioned step to add all solutions that need to dispose to cask 1 in proper order;

after the adding is finished, the through hole 9 on the upper side is in a closed state, the motor 13 is started, the motor 13 drives the rotating shaft 2 to rotate clockwise, the rotating shaft 2 drives the blades 3 to rotate clockwise, the blades 3 start to stir the liquid medicine in the barrel 1, meanwhile, the rotating shaft 2 drives the spiral plate 16 to rotate clockwise, and the spiral plate 16 enables the liquid medicine on the upper side of the barrel 1 to flow downwards to the blades 3, so that the liquid medicine in the barrel 1 is fully mixed;

after the mixing is finished, the needle cap 17 is detached from the needle cylinder 5, then an infusion bag is taken out, the needle head is inserted into the infusion bag, the pulling plate 15 is pulled backwards, the pulling plate 15 drives the piston 6 to slide forwards in the needle cylinder 5 through the pulling rod 14, negative pressure is formed on the rear side of the needle cylinder 5, as the one-way liquid outlet valve 7 at the rear end of the needle cylinder 5 can only discharge liquid outwards, and the one-way liquid inlet valve 18 in the liquid inlet pipe 4 can only feed liquid into the needle cylinder 5, the liquid medicine in the barrel 1 enters the needle cylinder 5 through the liquid inlet pipe 4, the pulling plate 15 is moved backwards, the pulling plate 15 drives the piston 6 to slide backwards through the pulling rod 14, the piston 6 extrudes the liquid medicine in the needle cylinder 5 into the infusion bag through the needle head, and then the above operations are repeated until all the liquid medicine in the barrel 1 enters the.
