Description

Technical Field

[0001] The utility model relates to the technical field of sodium fusidate liquid medicine dispensing, in particular to a sodium fusidate freeze-dried powder injection liquid medicine dispensing device. Background Art

[0002] The ingredients of sodium fusidate freeze-dried powder injection mainly include sodium fusidate and other excipients. The specific proportion and type of ingredients may vary according to different manufacturers and product specifications. The ingredients of sodium fusidate freeze-dried powder injection are generally mixed with sodium fusidate and solvents and other excipients, and fully dissolved. This step can be carried out using an agitator or mixer. The stirring speed and time need to be properly controlled, and attention should be paid to the bubbles generated during stirring.

[0003] The Chinese patent authorization announcement number: CN209810065U provides a liquid medicine dispensing device. The solution is provided by setting a rotating disk, and the stirring shaft rotates while floating up and down, thereby driving the blades to float up and down, changing the rotation position of the blades, increasing the stirring range of the blades, and improving the mixing effect of the liquid medicine. By setting the adjusting bolt and the adjusting block, the adjusting bolt drives the adjusting block to rotate, and the ellipsoidal adjusting block rotates to apply pressure to the adjusting plate, changing the position of the adjusting plate in the connecting hole, thereby compressing the support spring and changing the elastic force applied by the support spring to the stirring shaft. However, when mixing and stirring the liquid medicine ingredients of sodium fusidate freeze-dried powder injection, attention should be paid to the bubbles generated during stirring. The generation of bubbles may affect the stability of the liquid medicine, causing changes in the drug components, thereby affecting the efficacy. The generation of bubbles may affect the absorption and utilization of the drug, thereby affecting the therapeutic effect. The generation of bubbles may affect the safety of the drug, because the bubbles may contain air or other impurities, which may cause allergic reactions or other adverse reactions. Air pressure is usually used to reduce bubbles, but this method is cumbersome to operate and has high cost.

[0004] Therefore, it is necessary to provide a sodium fusidate freeze-dried powder injection liquid dosage device to solve the above technical problems. Utility Model Content

[0022] See also Figures 1 to 4 The present utility model provides a sodium fusidate freeze-dried powder injection liquid medicine dispensing device, comprising: a mounting base 1, wherein a liquid medicine dispensing mixing component 2 is disposed in the middle of the mounting base 1;

[0023] The liquid medicine mixing component 2 includes a mixing barrel 201 fixedly connected to the middle of the mounting base 1, the upper end of the mixing barrel 201 is fixedly connected to a driving shell 202, the middle of the driving shell 202 is fixedly connected to a feeding pipe 203, and the upper end of the feeding pipe 203 is connected to a feeding sealing cover 204 by a threaded rotation, the mixing barrel 201 is connected to the outside world through the feeding pipe 203, the middle of the driving shell 202 is also fixedly connected to an exhaust hole 205, the mixing barrel 201 is connected to the outside world through the exhaust hole 205, and the lower end of the mixing barrel 201 is connected to a discharge sealing cover 206 by a threaded rotation.

[0024] A servo motor 207 is fixedly connected to the inside of the driving housing 202, and a half gear 208 is fixedly connected to the output end of the servo motor 207. The middle part of the driving housing 202 is rotatably connected to the first rotating rod 209, the second rotating rod 210 and the third rotating rod 211. The middle parts of the first rotating rod 209, the second rotating rod 210 and the third rotating rod 211 and located inside the driving housing 202 are fixedly connected with driven gears 212, and multiple driven gears 212 are all meshed and connected with the half gear 208.

[0025] A plurality of stirring blades 213 are fixedly connected to the lower ends of the first rotating rod 209 , the second rotating rod 210 and the third rotating rod 211 and are located inside the mixing barrel 201 .

[0026] The length of the first rotating rod 209 is twice the length of the second rotating rod 210 , and the length of the second rotating rod 210 is twice the length of the third rotating rod 211 .

[0027] The plurality of stirring blades 213 are all arranged at an angle;

[0028] The inclined arrangement of the stirring blades 213 can reduce the impact contact surface of the sodium cedide lyophilized powder injection liquid during rotation, further reducing the probability of bubble generation.

[0029] The lower end of the mixing barrel 201 is conical;

[0030] The conical lower end of the mixing barrel 201 makes it easier to discharge the mixed materials.

[0031] During operation, it is only necessary to rotate the feed sealing cover 204 to open it, and then pour the proportioned liquid medicine ingredients into the mixing barrel 201 through the feed pipe 203, and then start the first rotating rod 209, which drives the half gear 208 fixedly connected to the output end to rotate, and the rotation of the half gear 208 drives the multiple driven gears 212 meshing with it to rotate.

The second rotating rod 210 and the third rotating rod 211 rotate intermittently to drive the multiple stirring blades 213 fixedly connected to the lower end to rotate intermittently. The intermittent rotation reduces the probability of internal bubbles during stirring. At the same time, the inclined stirring blades 213 can reduce the impact contact surface of the sodium fusidate freeze-dried powder injection liquid during rotation, further reducing the probability of bubble generation. By setting the first rotating rod 209, the second rotating rod 210 and the third rotating rod 211 to different lengths, the sodium fusidate freeze-dried powder injection liquid in the mixing barrel can be rotated and stirred at the upper, middle and lower positions respectively without overlapping, thereby reducing the probability of bubble generation and increasing the uniformity of mixing.
