Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical preparation, and in particular to a clinical pharmaceutical preparation device. Background Technology

[0002] Currently, the announcement number CN 221471700 U, entitled "A Clinical Pharmaceutical Preparation Device", discloses a clinical pharmaceutical preparation device. In this device, a lead screw drives a screw sleeve to move up and down reciprocally, the screw sleeve drives a movable rod to move up and down reciprocally, and the movable rod drives a cleaning sleeve to move up and down. Thus, the cleaning sleeve cleans the pharmaceutical residue on the stirring shaft, while the screw sleeve cleans the lead screw simultaneously.

[0003] In this way, the lead screw drives the stirring shaft to stir, and through the screw connection between the lead screw and the screw sleeve, the lead screw drives the screw sleeve and the cleaning sleeve connected to the screw sleeve to move up and down. However, during this process, the thick paste-like agent is very easy to adhere to the threads of the lead screw, causing the screw connection between the screw sleeve and the lead screw to jam and making it difficult for the screw sleeve to move up and down. In severe cases, it may even cause damage to the equipment.

[0004] Therefore, there is an urgent need for a clinical pharmaceutical preparation device that can simultaneously mix and clean the pharmaceuticals from the stirring rod while improving the device's safety. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a clinical pharmaceutical preparation device that improves the safety of the device while achieving the mixing and stirring of the preparation and cleaning of the preparation on the stirring rod.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A clinical pharmaceutical preparation device includes a preparation container. A preparation preparation shaft is rotatably connected to the top wall of the preparation container. Multiple stirring rods are connected to the preparation preparation shaft. A first cleaning ring is sleeved on the outer wall of the preparation preparation shaft, and a second cleaning ring is sleeved on the outer wall of each stirring rod. The second cleaning ring is connected to the first cleaning ring. One or more limiting posts are provided on the bottom surface of the preparation container. A hollow cavity is formed on the preparation preparation shaft from the bottom surface of the shaft. The extension direction of the hollow cavity and the extension direction of the limiting posts are both consistent with the extension direction of the preparation preparation shaft. The limiting posts are partially or entirely located within the hollow cavity. A magnetic element is screwed into the hollow cavity. The magnetic element is slidably connected to the limiting posts and magnetically attracted to the first cleaning ring.

[0008] Furthermore, the hollow cavity wall is provided with an internal thread, and the outer wall of the magnetic component is provided with an external thread, and the internal thread and the external thread are engaged.

[0009] Furthermore, the second cleaning ring is connected to a connecting rod, which is slidably connected to the first cleaning ring.

[0010] Furthermore, the outer wall of the first cleaning ring is provided with a convex annular connecting groove, and a connecting ball is fixed at the end of the connecting rod away from the second cleaning ring, the connecting ball being disposed within the convex annular connecting groove.

[0011] Furthermore, the drug modulation shaft is connected to a forward and reverse rotation mechanism, which causes the drug modulation shaft to rotate forward and reverse alternately.

[0012] Furthermore, the forward and reverse mechanism includes a first gear, a second gear, a third gear, a fourth gear, and a fifth gear. The first gear is coaxially connected to the drug dispensing shaft. The first gear meshes with the second gear. The second gear is coaxially connected with the third gear. The fourth gear meshes with the fifth gear. An equal number of conductive elements are fixed on the gear surfaces of the fourth and fifth gears. When the teeth of the third gear mesh with the conductive elements on the fourth gear, the teeth of the third gear do not mesh with the conductive elements on the fifth gear. When the teeth of the third gear do not mesh with the conductive elements on the fourth gear, the teeth of the third gear mesh with the conductive elements on the fifth gear.

[0013] Furthermore, the gear ratio between the second gear and the first gear is greater than 3.

[0014] Furthermore, the drug dispensing shaft is connected to a rotating handle.

[0015] Furthermore, the bottom of the drug preparation shaft is sealed to the bottom surface of the preparation container.

[0016] Furthermore, there is one limiting post, which is a polygonal prism. The magnetic component has a polygonal hole, and the polygonal prism is disposed inside the polygonal hole with a clearance fit between the polygonal prism and the polygonal hole.

[0017] The beneficial effects of this utility model are:

[0018] The magnetic component slides through the limiting post, and the outer wall of the magnetic component is screwed into the hollow cavity. The rotation of the drug preparation shaft drives the magnetic component to slide. Through the magnetic attraction between the magnetic component and the first cleaning ring, the sliding of the magnetic component drives the first cleaning ring to slide, and further drives the second cleaning ring to slide. The first and second cleaning rings clean the drug preparation shaft and the stirring rod respectively. This prevents jamming caused by the concentration of the drug and improves the safety of the device. Attached Figure Description

Detailed Implementation

[0029] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0030] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0031] Example 1:

[0032] like Figures 1 to 7 As shown, a clinical pharmaceutical preparation device includes a preparation tank, a preparation preparation shaft 3 rotatably connected to the top wall of the preparation tank, a plurality of stirring rods 4 connected to the preparation preparation shaft 3, a first cleaning ring 5 sleeved on the outer wall of the preparation preparation shaft 3, and a second cleaning ring 6 sleeved on the outer wall of the stirring rods 4, the second cleaning ring 6 being connected to the first cleaning ring 5.

[0033] One or more limiting posts 7 are provided on the bottom surface of the mixing barrel. A hollow cavity 8 is formed on the bottom surface of the drug mixing shaft 3. The extension direction of the hollow cavity 8 and the extension direction of the limiting posts 7 are both consistent with the extension direction of the drug mixing shaft 3. The limiting posts 7 are partially or entirely located in the hollow cavity 8. A magnetic component 9 is screwed into the hollow cavity 8. The magnetic component 9 is slidably connected to the limiting posts 7 and magnetically attracted to the first cleaning ring 5.

[0034] The magnetic component 9 is slidably connected to the limiting post 7, and the outer wall of the magnetic component 9 is screwed to the hollow cavity 8. The rotation of the drug preparation shaft 3 drives the magnetic component 9 to slide. Through the magnetic attraction between the magnetic component 9 and the first cleaning ring 5, the sliding of the magnetic component 9 drives the first cleaning ring 5 to slide, and further drives the second cleaning ring 6 to slide. The first cleaning ring 5 and the second cleaning ring 6 clean the drug preparation shaft 3 and the stirring rod 4 respectively. This will prevent jamming caused by the concentration of the drug and improve the safety of the device.

[0035] The sliding direction of the magnetic component 9 is consistent with the extension direction of the drug modulation shaft 3.

[0036] The hollow cavity 8 has an internal thread 10 on its wall, and the magnetic component 9 has an external thread on its outer wall. The internal thread 10 mates with the external thread.

[0037] The second cleaning ring 6 is connected to a connecting rod 12, which is slidably connected to the first cleaning ring 5.

[0038] The outer wall of the first cleaning ring 5 is provided with a convex annular connecting groove 13, and a connecting ball 14 is fixed at the end of the connecting rod 12 away from the second cleaning ring 6. The connecting ball 14 is located in the convex annular connecting groove 13.

[0039] The bottom of the drug preparation shaft 3 is sealed to the bottom of the preparation barrel.

[0040] The bottom surface of the mixing barrel is provided with an annular protrusion 15, and the bottom of the drug mixing shaft 3 is provided with an annular groove 16 that cooperates with the annular protrusion 15. A sealing ring is provided in the annular groove 16.

[0041] The limiting post 7 is a single prism, and the magnetic component 9 is provided with a polygonal hole 17. The polygonal prism is disposed in the polygonal hole 17, and the polygonal prism and the polygonal hole 17 are in clearance fit.

[0042] The polygonal prism is a pentagonal prism, with 17 polygonal holes in pentagonal shape.

[0043] The mixing barrel includes a barrel body 1 and a top cover 2, and the top cover 2 is sealed to the mixing barrel.

[0044] The top cover 2 is provided with one or more inlets 18.

[0045] Example 2:

[0046] like Figures 1 to 7 As shown, Embodiment 2 has all the features of Embodiment 1, except that:

[0047] The drug modulation shaft 3 is connected to a forward and reverse rotation mechanism, which causes the drug modulation shaft 3 to rotate forward and reverse alternately.

[0048] If the dispensing shaft rotates continuously in one direction, the magnetic component 9 will slide beyond the hollow cavity 8, potentially damaging the equipment. However, the forward and reverse mechanism, which rotates the dispensing shaft several times forward and then several times in reverse, allows the magnetic component 9 to slide back and forth between the top and bottom of the hollow cavity 8, further improving safety.

[0049] The forward and reverse rotation mechanism includes a first gear 19, a second gear 20, a third gear 21, a fourth gear 22, and a fifth gear 23. The first gear 19 is coaxially connected to the medicine dispensing shaft. The first gear 19 meshes with the second gear 20. The second gear 20 is coaxially connected with the third gear 21. The fourth gear 22 meshes with the fifth gear 23. An equal number of transmission elements 24 are fixed on the gear surfaces of the fourth gear 22 and the fifth gear 23. When the teeth of the third gear 21 mesh with the transmission elements 24 on the fourth gear 22, the teeth of the third gear 21 do not mesh with the transmission elements 24 on the fifth gear 23. When the teeth of the third gear 21 do not mesh with the transmission elements 24 on the fourth gear 22, the teeth of the third gear 21 mesh with the transmission elements 24 on the fifth gear 23.

[0050] The first gear 19, the second gear 20, the third gear 21, the fourth gear 22, and the fifth gear 23 are all rotatably connected to the bottom of the top cover 2.

[0051] The fifth gear 23 is connected to a rotating motor 25 or a rotating handle.

[0052] When the forward and reverse mechanism is working, the fourth gear 22 meshes with the fifth gear 23, so their rotations are in opposite directions. When the teeth of the third gear 21 mesh with the transmission element 24 on the fourth gear 22 but not with the transmission element 24 on the fifth gear 23, the rotation of the third gear 21 is transmitted from the fourth gear 22. When the teeth of the third gear 21 do not mesh with the transmission element 24 on the fourth gear 22 but mesh with the transmission element 24 on the fifth gear 23, the rotation of the third gear 21 is transmitted from the fifth gear 23. In this way, the rotation of the third gear 21 can achieve alternating forward and reverse rotation. Through the transmission between the second gear 20 and the first gear 19, the forward and reverse rotation of the drug dispensing shaft can be achieved.

[0053] The gear ratio between the second gear 20 and the first gear 19 is greater than 3.

[0054] The gear ratio between the second gear 20 and the first gear 19 is not less than twice the number of 10 internal thread turns.

[0055] This design allows for a larger sliding range of the magnetic component 9 and a larger cleaning area.

[0056] Example 3:

[0057] like Figure 8 As shown, Embodiment 3 has all the features of Embodiment 1, except that:

[0058] The drug preparation shaft 3 is connected to a rotating handle.

[0059] By turning the handle, the dispensing shaft can be manually rotated to prevent it from rotating in one direction continuously.

[0060] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
