Example 1

As shown in Figures 1-6, the present invention proposes a drug delivery device, which includes a main body 10, a base 20, and a motor 8. The main body 10 is internally provided with a second sliding groove 3, the second sliding groove 3 is slidably connected to a first sliding block 4, the main body 10 is internally provided with a second groove 6, the second groove 6 is internally provided with a fourth sliding groove 27, the fourth sliding groove 27 is slidably connected to a second sliding block 5, and the internal elastic connection of the main body 10 is spring 24, the spring 24 is fixedly connected to a baffle 25 on the side away from the main body 10, and the baffle 25 is slidably connected to the fourth sliding groove 27;

The output end of motor 8 is equipped with a first rotating shaft 9. The side of the first rotating shaft 9 away from motor 8 is connected to a first rotating wheel 12 for rotation. The outer rotation of the first rotating wheel is connected to a belt 13, and the side of the belt 13 away from the first rotating wheel 12 is connected to a second rotating wheel 16 for rotation. The outer fixed connection of the second rotating wheel 16 is connected to a rotating disc 17, and the outer fixed connection 7505632 of the base 20 is connected to a supporting rod 14. The inner part of the supporting rod 14 is equipped with a third groove 29, the third groove 29 rotates to connect the extrusion rod 15.

The working principle of a drug delivery device proposed by the present invention is to place drugs required by heart failure patients into a drug storage tank 2. At this time, the first sliding block 4, which is sliding connected to the second sliding groove 3 inside the main body 10, will block the drugs in the drug storage tank 2, so that the drugs in the drug storage tank 2 will not fall into the second groove 6.

When heart failure patients need to use drugs, at this time, the first sliding block 4 in the second sliding groove 3 will be slid, Make the first sliding block 4 no longer block the medication in the drug storage tank 2. At this time, as there is no obstruction at the lower end of the medication in the drug storage tank 2, the medication will fall into the second groove 6. Due to the fourth sliding groove 27 opened in the second groove 6, the length of the fourth sliding groove 27 is fixed, and the lower ends of the second sliding block 5 and the baffle 25 are in an L-shape, which facilitates the sliding of the second sliding block 5 and the baffle 25 in the fourth sliding groove 27, When the second sliding block 5 and the baffle 25 slide to opposite sides in the fourth sliding groove 27;

At this point, the distance between the second sliding block 5 and the baffle 25 is fixed to the size of one tablet. The medication that falls into the second groove 6 due to sliding the first sliding block 4 will accurately fall between the second sliding block 5 and the baffle 25. At this time, push the second sliding block 5 towards the baffle, causing the second sliding block 5 to move inward towards the baffle 25 in the fourth sliding groove 27. Due to the movement of the second sliding block 5, the second sliding block 5 will push the medication that falls into the second groove 6 towards the baffle 25, At this time, the tablet is pushed by thesecond sliding block 5, and the tablet will push the baffle 25 to move. Due to the thrust on the baffle 25, the baffle 25 will compress the spring 24. As the lower end of the baffle 25 is L-shaped and slides in the fourth sliding groove 27, the baffle 25 is easily pushed. When the spring 24 compresses for a certain distance, the tablet will enter the drug outlet 23 7505632 and fall into the rotating disc 17. When a patient with heart failure needs to take a certain medication separately, the first sliding block 4 in the second sliding groove 3 corresponding to this drug can be slid, so that this first sliding block 4 will not block the tablets in the corresponding drug storage tank 2. At this time, the drugs in the corresponding drug storage tank 2 will fall into the second groove 6, and then the drugs will enter the drug outlet 23 by pushing the second sliding block 5;

When the medication required by patients with heart failure enters the rotating disc 17, motor 8 can be started to drive the first rotating shaft 9 set at the output end to rotate. When the first rotating shaft 9 rotates, it will cause the first rotating wheel 12 connected to the rotation to rotate. When the first rotating wheel 12 rotates, it will cause the belt 13 connected to the external rotation of the first rotating wheel 12 to rotate. After the belt 13 rotates, It will cause the belt 13 to rotate away from the side of the first rotating wheel 12, and the second rotating wheel 16 connected to it will also rotate. At this time, the external fixed connection rotating disc 17 of the second rotating wheel 16 will rotate together with the second rotating wheel 16. At this time, due to the contact between the rotating disc 17 and the extrusion rod 15, the extrusion rod 15 connected to the external fixed connection supporting rod 14 of the base 20 will rotate with the rotation of the turntable 17, The rotation of the squeezing rod 15 inside the rotating disc 17 will exert a squeezing effect on the tablets inside the rotating disc 17, facilitating the crushing of the tablets.
