By setting the lifting block 2406, it is beneficial to add sepsis coagulopathy nursing drugs through the syringe 8. In order to improve the convenience of automatic addition of drugs by the syringe 8, the piston rod 12 can be installed to the inner wall of the positioning block 6, and then the fourth servo motor 2402 is turned on to drive the threaded slide rod 2403 to slide along the inner wall of the third fixed groove 2404 through the rotation of the second threaded rod 2401.

[0059] The present invention also provides a drug proportioning and delivery device and a proportioning method thereof, the method comprising the following steps:

[0060] S1. First, place the syringe 8 on the inner wall of the positioning block 6, and turn on the third servo motor 2301 to drive the threaded slider 2303 to slide along the inner wall of the second fixed groove 2304 through the rotation of the first threaded rod 2302. At the same time, drive the rotating rod 2305 to rotate along the outer wall of the positioning block 6.

[0061] S2. Then, according to the need of intermittent addition of different drugs in the mixing dish 4, the second servo motor 2201 can be turned on to drive the driving gear 2203 to rotate through the rotation of the connecting gear 2202. The rotation of the driving gear 2203 drives the connecting rod 2205 to rotate through the connection of the rotating block 2204. The rotation of the connecting rod 2205 drives the connecting column 2206 to slide along the inner wall of the slide groove 2208. At the same time, the connecting column 2206 slides along the inner wall of the slide groove 2208, driving the intermittent disk 2207 to rotate intermittently, and under the fixed connection of the connecting shaft 2210, drives the connecting frame 2 to rotate intermittently, and then drives the four groups of syringes 8 to perform intermittent adjustment movements, so as to achieve the effect of adjusting the addition of different drugs to the mixing dish 4.

[0062] S3. Next, the fourth servo motor 2402 can be turned on to drive the threaded slide bar 2403 to slide along the inner wall of the third fixed groove 2404 through the rotation of the second threaded rod 2401.

[0063] S4. After the addition of medicine to the mixing dish 4 directly below the syringe 8 is completed, in order to improve the convenience of automatic loading of the subsequent mixing dish 4 and the convenience of automatically pushing and taking the medicine in the matched mixing dish 4, the first servo motor 14 can be turned on to drive the swing rod 16 to rotate through the rotation of the synchronous belt 15. The rotation of the swing rod 16 drives the sliding rod 17 to slide along the inner walls of the first limiting groove 18 and the first fixed groove 19. The sliding of the sliding rod 17 drives the material removing rod 20 to slide back and forth in a "mouth" shape, thereby achieving the effect of automatic loading and automatic unloading and taking linkage of the mixing dish 4.

[0065] Next, when adjusting and adding different drugs for the nursing of sepsis coagulopathy through the syringe 8, the second servo motor 2201 can be turned on to drive the driving gear 2203 to rotate through the rotation of the connecting gear 2202. The rotation of the driving gear 2203 drives the rotating block 2204 and the connecting rod 2205 to rotate synchronously. The rotation of the connecting rod 2205 drives the connecting column 2206 to slide intermittently along the inner wall of the slide groove 2208, and under the sliding connection between the intermittent groove 2209 and the rotating block 2204, drives the intermittent disk 2207 fixedly connected to the connecting shaft 2210 to perform intermittent rotational movement, which drives the connecting frame 2 to perform intermittent rotational movement, so as to achieve the effect of adjusting and adding nursing drugs to different drug syringes 8;

[0066] Next, when the sepsis coagulopathy nursing drug is added and used through the syringe 8, in order to improve the stability of the syringe 8 placed on the connecting frame 2, the syringe 8 can be connected to the positioning block 6, and then the third servo motor 2301 is turned on to drive the threaded slider 2303 to slide along the inner wall of the second fixed groove 2304 through the rotation of the first threaded rod 2302. At the same time, the threaded slider 2303 is driven to slide along the inner wall of the second limiting groove 2306, which plays a role in driving the rotating rod 2305 to rotate conveniently, so as to achieve the effect of driving the clamping block 7 to effectively engage and fix the syringe 8;

[0067] Finally, when adding sepsis coagulopathy care drugs through the syringe 8, in order to improve the convenience of automatic addition of drugs by the syringe 8, the piston rod 12 can be installed on the inner wall of the positioning block 6, and then the fourth servo motor 2402 is turned on to drive the threaded slide rod 2403 to slide along the inner wall of the third fixed groove 2404 through the rotation of the second threaded rod 2401. The sliding of the threaded slide rod 2403 is connected through the lifting rod 2405, driving the lifting block 2406 fixedly connected to the slide rail rod 2407 to perform lifting and lowering movements, thereby achieving the effect of automatically lifting and lowering the piston rod 12 in the syringe 8.
