[0023] Please also read Figure 1 , Figure 2 , Figure 4 , Fig. 9 , Fig.18 , Fig.19 , Fig. 22 , Fig.23 , Fig.24 and Fig.29, the intravenous drug dispensing device provided by the present invention is now described. The intravenous drug dispensing device comprises a workbench 21, a first mounting seat 11, a supporting member 18, a first clamping assembly 26 and a second clamping assembly 34. The first mounting seat 11 is fixedly mounted on the workbench 21. The supporting member 18 is connected to the first mounting seat 11, and the supporting member 18 is provided with a first notch 181 for the bottle mouth of the PP bottle 1120 to slide into or out of, and the first notch 181 is provided with a U-shaped limiting groove 182 for the annular protrusion 11201 on the bottle mouth of the PP bottle 1120 to slide into or out of. The first clamping assembly 26 is arranged on the workbench 21, and the first clamping assembly 26 has two clamping jaws 261, and the two clamping jaws 261 can clamp or release the ampoule bottle 2180 in a vertical state. The second clamping assembly 34 is disposed on the workbench 21 . The second clamping assembly 34 includes an elastic clamping member 341 . The elastic clamping member 341 has two second clamping portions 3411 . The two second clamping portions 3411 can clamp the bottle mouth of the vial 310 through elastic deformation.

[0024] Compared with the prior art, the intravenous drug dispensing device provided by the present invention slides the bottle head of the PP bottle 1120 into the first notch 181, and the annular protrusion 11201 on the bottle mouth of the PP bottle 1120 slides into the U-shaped limiting groove 182 synchronously, so that the PP bottle 1120 and the supporting member 18 are slidably connected together; the ampoule bottle 2180 in a vertical state is placed between the two clamping claws 261, so that the two clamping claws 261 clamp the ampoule bottle 2180. The bottle mouth of the syringe bottle 310 is placed between the two second clamping parts 3411, so that the two second clamping parts 3411 clamp the bottle mouth of the syringe bottle 310 through elastic deformation. In this way, the medical staff only needs to hold the syringe 19 to extract the liquid from the bottle body, thereby avoiding the coordination error as much as possible, that is, avoiding the problem that the needle 194 on the syringe 19 may stab the medical staff as much as possible.

[0025] In this embodiment, the body of the PP bottle 1120 can be in an inclined state with the bottle mouth inclined upward, and the supporting member 18 is in a state of supporting the PP bottle 1120. The U-shaped limiting groove 182 limits the position of the annular protrusion 11201 on the bottle mouth of the PP bottle 1120, so that the needle 194 can smoothly penetrate into the PP bottle 1120. The first clamping assembly 26 can use a force-controlled mechanical clamp 261, and specifically, can use a RM-GB-F precision force-controlled servo clamp 261. Of course, the first clamping assembly 26 can also use other existing technologies.

[0026] In some embodiments, see Fig.15 and Fig.16The intravenous drug dispensing device also includes a second mounting seat 22, a knocking piece 23, a second driving assembly 24 and a rotating platform 25. The second mounting seat 22 is fixedly mounted on the workbench 21. The knocking piece 23 is connected to the second mounting seat 22 in a sliding manner in the horizontal direction. The second driving assembly 24 is used to drive the knocking piece 23 to slide. The base of the rotating platform 25 is fixedly connected to the workbench 21, and the rotation axis of the turntable 251 in the rotating platform 25 is vertically arranged. Among them, the first clamping assembly 26 is fixedly mounted on the turntable 251, so that the first clamping assembly 26 is arranged on the workbench 21. When the rotation of the turntable 251 causes the first clamping assembly 26 to reach the knocking station, the sliding of the knocking piece 23 enables the knocking piece 23 to knock the bottle head of the ampoule bottle 2180 clamped by the two clamps 261, thereby knocking off the bottle head of the ampoule bottle 2180. In order to knock off the bottle head of the ampoule bottle by the knocking piece 23, a grinding wheel can be used to scratch the bottleneck groove of the ampoule bottle 2180. The second driving component 24 can be fixed on the second mounting seat 22. The second driving component 24 can be a push-pull electromagnet. The movable sliding rod in the second driving component 24 can slide back and forth along the sliding direction of the knocking piece 23 and is fixedly connected to the knocking piece 23. Of course, the second driving component 24 can also be a cylinder or a hydraulic cylinder.

[0027] In some embodiments, see Fig. 22 , Fig.23 and Fig.24 , the intravenous drug dispensing equipment also includes a third mounting seat 32 and a third power source assembly 33. The third mounting seat 32 is fixed on the workbench 21. The third power source assembly 33 is arranged on the third mounting seat 32, and the third power source assembly 33 includes a rotatable second connecting member 331. Among them, the second clamping assembly 34 is connected to the second connecting member 331, so as to realize that the second clamping assembly 34 is arranged on the workbench 21. When dispensing medicine, it is often necessary to inject physiological saline as a solvent into the syringe bottle 310, and then fully mix the physiological saline and the solid medicine in the syringe bottle 310. In this embodiment, the rotation of the second connecting member 331 in the third power source assembly 33 can make the physiological saline and the solid medicine in the syringe bottle 310 evenly mixed.

[0028] In some embodiments, see Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Fig.12 , Fig.13 and Fig.14The intravenous drug dispensing device also includes a first power source assembly 12, a second power source assembly 13, an assembly 14, a positioning clamp 15, a sliding member 16 and a first driving assembly 17. The first power source assembly 12 is arranged on the first mounting seat 11, and the first power source assembly 12 includes a first connecting member 121 that can rotate around a horizontal axis. The second power source assembly 13 is fixedly arranged on the first connecting member 121, and the second power source assembly 13 has a load slide 131 that can reciprocate linearly, and the movement direction of the load slide 131 is perpendicular to the rotation axis of the first connecting member 121. The assembly 14 is fixedly connected to the load slide 131. The positioning clamp 15 is fixedly connected to the assembly 14, and the positioning clamp 15 is used to connect with the outer sleeve 191 in the syringe 19. The sliding member 16 is slidably connected to the assembly 14 and the sliding direction is parallel to the moving direction of the load slide 131. The sliding member 16 is connected to the hand 192 in the syringe 19, so that the sliding of the sliding member 16 can pull or push the hand 192. The first driving assembly 17 is used to drive the sliding member 16 to slide. When the turntable 251 and the second connecting member 331 are rotated to their respective preset positions, the rotation of the first connecting member 121 can align the needle 194 in the syringe 19 with the bottle mouth of the PP bottle 1120 on the supporting member 18, or the bottle mouth of the ampoule bottle 2180 clamped by the two clamping claws 261, or the bottle mouth of the cillin bottle 310 clamped by the two second clamping parts 3411. The outer sleeve 191 of the syringe 19 is connected to the positioning clamp 15, and the handle 192 in the syringe 19 is connected to the sliding member 16. Then the first connecting member 121 in the first power source assembly 12 rotates until the needle 194 of the syringe 19 is aligned with the bottle mouth of the PP bottle 1120, the ampoule bottle 2180 or the vial 310, and then the load slide 131 in the second power source assembly 13 slides, so that the needle 194 penetrates the bottle body, and then the first driving assembly 17 drives the sliding member 16 to slide, thereby pulling the hand 192 in the syringe 19, and then the liquid in the bottle body. In this way, the problem that the needle 194 on the syringe 19 may injure the medical staff is further reduced.

[0029] In this embodiment, the second power source assembly 13 may adopt a return type servo push rod, and the second power source assembly 13 may specifically adopt an RM-RLA return type servo push rod.

[0030] In some embodiments, see Figure 3 and Fig.13 The positioning clamp 15 is elastic and has a first clamping portion 151 in an arc-shaped structure, and the first clamping portion 151 is used to accommodate and clamp the outer jacket 191. The outer jacket 191 is inserted into the first clamping portion 151, and the first clamping portion 151 clamps the outer jacket 191 through elastic deformation, thereby connecting the outer jacket 191 and the positioning clamp 15 together.

[0031] In some embodiments, see Figure 3 and Fig.13 The positioning clamp 15 also has a limiting portion 152 in an arc-shaped structure, and the limiting portion 152 is used to cooperate with the first clamping portion 151 to clamp the curling edge 1911 of the outer sleeve 191. In this way, when the sliding member 16 pushes and pulls the handle 192, the limiting portion 152 can limit the outer sleeve 191 with the first clamping portion 151. When the outer sleeve 191 is withdrawn from the first clamping portion 151, the curling edge 1911 also withdraws from between the first clamping portion 151 and the limiting portion 152. In this embodiment, the limiting portion 152 is located between the curling edge 1911 and the handle 192 and is sleeved outside the core rod 193 in the syringe 19.

[0032] In some embodiments, see Fig.13 The number of the first clamping parts 151 is two, thereby ensuring the reliability of the connection between the positioning clamping member 15 and the outer sleeve 191. The limiting part 152 cooperates with one of the first clamping parts 151 to clamp the curling edge 1911.

[0033] In some embodiments, see Figure 3 and Fig.14 The sliding member 16 has a first fitting portion 161 and a second fitting portion 162, and the first fitting portion 161 and the second fitting portion 162 are slidably fitted with the pressing handle 192 from both sides. In this way, when the outer sleeve 191 is inserted into the first clamping portion 151, the pressing handle 192 simultaneously slides and penetrates between the first fitting portion 161 and the second fitting portion 162, thereby slidingly connecting the pressing handle 192 and the sliding member 16 together. In this embodiment, the second fitting portion 162 is located between the outer sleeve 191 and the pressing handle 192 and is provided with a second notch 1621, and the second notch 1621 is used for the core rod 193 to pass through.

[0034] In some embodiments, see Figure 3 and Figure 7 The intravenous drug dispensing device further includes a third slide rail 110 and a third slider 1110. The third slide rail 110 is arranged along the sliding direction of the sliding member 16 and is fixedly connected to the assembly 14. The third slider 1110 is slidably connected to the third slide rail 110, and the third slider 1110 is fixedly connected to the sliding member 16. The sliding connection between the sliding member 16 and the assembly 14 can be achieved through the sliding cooperation between the third slider 1110 and the third slide rail 110. In this embodiment, two sets of the third slide rail 110 and the third slider 1110 can be provided.

[0035] In some embodiments, see Figure 2 , Figure 6 , Figure 7 and Fig.12The first driving assembly 17 includes a power assembly 171 and a first fixing member 172. The power assembly 171 is fixedly mounted on the assembly 14, and the power assembly 171 has a piston rod that can be extended and retracted along the sliding direction of the sliding member 16. The first fixing member 172 is fixedly connected to the piston rod of the power assembly 171 and the sliding member 16. The extension and retraction of the piston rod of the power assembly 171 drives the sliding member 16 to slide through the first fixing member 172. In this embodiment, the power assembly 171 can be one of an electric push rod, a cylinder or a hydraulic cylinder.

[0036] In some embodiments, see Figure 2 and Figure 5 The first power source assembly 12 further includes a first drive motor 122. The body of the first drive motor 122 is fixedly connected to the first mounting seat 11, and the output shaft of the first drive motor 122 is fixedly connected to the first connecting member 121. The output shaft of the first drive motor 122 can drive the first connecting member 121 to rotate.

[0037] As a connection method between the output shaft of the first drive motor 122 and the first connecting member 121, the first connecting member 121 can be directly fixedly connected to the output shaft of the first drive motor 122. Alternatively, the first connecting member 121 has a first shaft-shaped portion 1212 in a shaft-shaped structure, and the first shaft-shaped portion 1212 is fixedly connected to the output shaft of the drive motor via a coupling.

[0038] In some embodiments, see Figure 2 , Figure 5 , Figure 8 , Fig.10 and Fig.11, the first connecting member 121 has a circular surface 1211 coaxially arranged with the rotation axis of the first connecting member 121, and the intravenous drug dispensing device also includes a docking member 1130, a second drive motor 1140, a conversion member 1150 and a curved rod 1160.

The second fixing member 342 also has a third notch 34212 connected to the receiving space 3421, so that the syringe bottle 310 can enter between the two second clamping portions 3411 through the third notch 34212. Among them, the elastic clamping member 341 is connected to the second fixing member 342. The second fixing member 342 can protect the elastic clamping member 341 to a certain extent. In this embodiment, the syringe bottle 310 enters between the two second clamping portions 3411 through the third notch 34212. When the second clamping assembly 34 is at the material unloading station, the pushing portion 351 passes through the open end 34211 of the accommodating space 3421 and penetrates between the two second clamping portions 3411, thereby pushing the vial 310 between the two second clamping portions 3411. The mouth of the vial 310 penetrates into the accommodating space 3421, and the second fixing member 342 can limit the movement of the vial 310 along the length direction of the vial 310.
