The dispensing device 100 may mix the medicine powder in the medicine bottle 300 and the medicine liquid in the infusion bag 400 to complete dispensing. Vial 300 may be, for example, a vial of penicillin. It should be noted that the vial 300 and the bag 400 are not intrinsic to the dispensing device 100, but are fixed to the dispensing device 100 as foreign objects.

As shown in fig. 1 and 2, the apparatus 100 includes a base 110 and various components disposed on the base 110, wherein components such as a rotating assembly 120, a substrate 130, a clamping assembly 140, and the like are disposed at a position a in fig. 1, a pressure adjusting assembly 150 is disposed at a position B in fig. 2, details at a position a in fig. 1 are shown in fig. 3 and 4, and details at B position B in fig. 2 are shown in fig. 5 and 6.

As shown in fig. 1, 3 and 4, the base 110 is provided with a rotating assembly 120, the rotating assembly 120 is connected to the base plate 130, the base plate 130 is provided with a clamping assembly 140, and the clamping assembly 140 is used for fixing the medicine bottle 300, the infusion bag 400 and the adapter 200. The adapter 200 may be connected to the vial 300 and the infusion bag 400, respectively, to establish a fluid communication path between the vial 300 and the infusion bag 400, thereby facilitating mixing of the drug powder in the vial 300 with the fluid in the infusion bag 400. It should be noted that the adapter 200 is not an intrinsic component of the dispensing device 100, but rather is affixed to the dispensing device 100 as an external object. When the dispensing device 100 dispenses the medicament, the clamping component 140, the adaptor 200, the medicine bottle 300 and the infusion bag 400 are all located on the substrate 130, the substrate 130 is connected with the rotating component 120, and the rotating component 120 can drive the substrate 130 to rotate, so that the clamping component 140, the adaptor 200, the medicine bottle 300 and the infusion bag 400 on the substrate 130 are driven to rotate together.

It should be noted that the dispensing device 100 includes a plurality of holding assemblies 140, for example, as shown in fig. 3, the holding assembly 140-1 is used for holding the vial 300, and the holding assembly 140-2 is used for holding the infusion bag 400, and the invention is not limited to the number of holding assemblies 140 included in the dispensing device 100.

According to one embodiment, a translation assembly 170 is further disposed on the base plate 130, and the translation assembly 170 is connected to the holding assembly 140 for adjusting the position of the holding assembly 140 in the horizontal direction and/or the vertical direction and/or the inside-outside direction (which may be understood as the x-axis direction, the y-axis direction, and the Z-axis direction), so as to adjust the position of the medicine bottle 300, the infusion bag 400, and the adaptor 200 in the horizontal direction and/or the vertical direction and/or the inside-outside direction. It should be noted that one or more translation assemblies 170 may be included in the dispensing device 100, each translation assembly 170 corresponding to movement of an object (vial 300, bag 400, or adapter 200) in one direction (horizontal, vertical, or in-out), i.e., the number of translation assemblies 170 is determined by the number of moveable directions of the vial 300, bag 400, and adapter 200. For example, if vial 300 is movable in three directions, i.e., horizontal, vertical, and inside-out, then vial 300 requires three translation assemblies 170, e.g., as shown in fig. 3 and 4, translation assemblies 170-1, 170-2, and 170-3 are used to control the movement of vial 300 in the horizontal, vertical, and inside-out directions, respectively; the bag 400 may be moved in a vertical direction, and the bag 400 may require a translation assembly 170, e.g., as shown in fig. 3 and 4, the translation assembly 170-4 may be used to control the movement of the bag 400 in the vertical direction; the adaptor 200 can move in the inside-out direction, and the adaptor 200 requires only one translation assembly 170. The present invention does not limit the number of translation assemblies 170 included in the dispensing device 100.

According to an embodiment, a shaking mechanism 180 is further disposed on the base plate 130 (the shaking mechanism 180 is not shown in fig. 3 and 4), and the shaking mechanism 180 is connected to the clamping assembly 140 for fixing the medicine bottle 300, and can drive the clamping assembly 140 of the medicine bottle 300 to shake, so as to shake the medicine bottle 300. After the liquid medicine in the infusion bag 400 enters the medicine bottle 300, the shaking mechanism 180 shakes the medicine bottle 300, so that the medicine powder in the medicine bottle 300 is rapidly dissolved in the liquid medicine.

As shown in fig. 2, 5 and 6, a pressure regulating assembly 150 is disposed on the base 110, and the pressure regulating assembly 150 includes a cavity 152, a piston member 154 disposed in the cavity 152, and a moving mechanism 156 connected to the piston member 154. One end of the cavity 152 is connected to the adapter 200, and the adapter 200 is connected to the vial 300. According to one embodiment, lumen 152 is connected to adapter 200 via conduit 160, with adapter 200 being located at C in fig. 5, 6 (adapter 200 not shown in fig. 5, 6). The conduit 160 may be, for example, but not limited to, a hose of glue. The piston 154 is driven by the moving mechanism 156 to reciprocate linearly in the cavity 152, so as to discharge the air in the cavity 152 to the medicine bottle 300, generate positive pressure in the medicine bottle 300, and discharge the medicine liquid in the medicine bottle 300 to the infusion bag 400; or air in the medicine bottle 300 is sucked into the cavity 152, so that negative pressure is generated in the medicine bottle 300, and the medicine liquid in the infusion bag 400 flows into the medicine bottle 300.

According to one embodiment, the dispensing device 100 further comprises at least two recovery boxes for recovering the vial and the adapter, respectively. For example, as shown in fig. 1 and 2, the dispensing device 100 includes two recovery boxes 190 for recovering a vial 300 and an adapter 200 for completing dispensing, respectively.

passages

220, 230 extending through the base 210. The first channel 220 is a linear channel having one end 222 connected to the vial 300 and the other end 224 connected to the bag 400, and the first channel 220 is a fluid channel for communicating a liquid medicine between the vial 300 and the bag 400. The second channel 230 is in the form of a dogleg, one end 232 of which is connected to the vial 300 and the other end 234 of which is connected to the pressure regulating assembly 150 of the dispensing device 100, and more particularly, with reference to fig. 5 and 6, the port 234 is connected to one end of the chamber 152 by a conduit 160. The second passage 230 is a gas passage, and the pressure regulating assembly 150 regulates the gas pressure in the medicine bottle 300 through the second passage 230, thereby controlling the flow direction of the medicine in the first passage 220.

According to an embodiment, the two ends 222, 224 of the first channel 220 and the two ends 232, 234 of the second channel 230 are exposed out of the base 210, and the length of the connection end 222 of the first channel 220 and the vial 300 exposed out of the base 210 is greater than the length of the connection end 232 of the second channel 230 and the vial 300 exposed out of the base 210, that is, in fig. 7, the length of the section D is greater than the length of the section E, so that when a negative pressure is generated in the vial 300, only the port 222 may contact the liquid medicine in the vial 300, and the port 232 does not contact the liquid medicine in the vial 300, thereby preventing the liquid medicine in the vial 300 from flowing into the pressure regulating assembly 150 (i.e., the cavity 152) of the dispensing device 100 through the second channel 230.

According to one embodiment, the two ends 222, 224 of the first channel 220 and the end 232 of the second channel 230 connected to the vial 300 are sharp, so as to facilitate the first channel 220 and the second channel 230 to pierce the sealing cap (usually rubber material) of the vial 300 and the infusion bag 400 and enter the interior of the vial 300 and the infusion bag 400.
