Description

Technical Field

[0002] The dispensing of anti-tumor traditional Chinese medicine agents refers to combining a variety of Chinese medicinal materials with anti-cancer effects according to certain proportions and methods based on traditional Chinese medicine theory and clinical needs to form a form suitable for patients to take.

[0003] Currently, the dispensing operation of anti-tumor traditional Chinese medicine agents is mostly carried out manually. First, the required medicinal materials are put into a clean container according to the proportion and decocted. During the decocting process, the operator needs to stir regularly. After that, the decocted agent is poured into a clean gauze or filtered using a fine mesh sieve. When filtering, the operator needs to wear clean disposable gloves and press the flexible filtering materials such as gauze to separate the agent from the medicinal materials sufficiently. To ensure the clarity of the liquid medicine, multiple filtering operations are usually required. Finally, the agent available for patients to take is obtained. Therefore, it is rather inconvenient to manually dispense traditional Chinese medicine agents, and the dispensing operation of different liquid medicines according to the proportion can only be carried out after complete filtration. The actual operation process is cumbersome, and it is rather difficult to control the dispensing proportion of the agent.

Detailed implementation manners

[0033] Now, reference will be made to the attached Figures 1-16The present invention is described more fully hereinafter and presently preferred embodiments of the invention are shown in the accompanying drawings. However, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0034] An automatic dispensing device for anti-tumor traditional Chinese medicine preparations, as Figures 1-3 shown, includes a base 1, a support frame 2, a fixing frame 3, a mounting frame 4, a dispensing assembly 5 and a pressing mechanism 6. A support frame 2 is connected to the base 1, a fixing frame 3 is connected to the upper part of the support frame 2, four mounting frames 4 are connected to the fixing frame 3, a dispensing assembly 5 for dispensing the preparations is provided on the mounting frame 4, and a pressing mechanism 6 for extruding and discharging the preparations is provided at the bottom of the mounting frame 4.

[0035] Refer to the attached Figures 4-6 , the dispensing assembly 5 includes a storage cylinder 50, a pushing member 51, a filter valve 52, a connecting pipe 53, a confluence cylinder 54 and a discharge pipe 55. A plurality of storage cylinders 50 are snap-connected to the mounting frame 4. An opening is provided at the top of the storage cylinder 50 for introducing the preparations and discharging the remaining medicinal residues. A movable pushing member 51 is provided inside the storage cylinder 50, and a filter valve 52 is connected to the top of the storage cylinder 50. The connecting pipe 53 is connected to the top of the mounting frame 4, and the filter valve 52 is docked with the connecting pipe 53. The connecting pipes 53 are all connected to the confluence cylinder 54, and a discharge pipe 55 is connected to the bottom of the confluence cylinder 54. When the pushing member 51 is forced to move upward, it squeezes the preparations inside the storage cylinder 50, and cooperates with the filter valve 52 to discharge the liquid component of the preparations inside the storage cylinder 50 into the connecting pipe 53, while a small amount of medicinal residues carried in the fluid are intercepted by the filter valve 52 inside the storage cylinder 50. The liquid preparation is then drained through the connecting pipe 53 into the confluence cylinder 54. Since there is a certain pressure when the liquid preparation is extruded and discharged, a jet phenomenon will occur when the liquid preparation is introduced into the confluence cylinder 54, enabling the liquid preparation to be mixed inside the confluence cylinder 54 and finally discharged into the container through the discharge pipe 55.

[0036] In this embodiment, different storage cylinders 50 store different formulated liquid medicines of the target preparation. According to the different proportions of the different formulated liquid medicines in the target preparation, the pushing members 51 inside the storage cylinders 50 are forced to move upward in proportion, squeezing the preparations inside the storage cylinders 50 into the connecting pipe 53 in proportion. Therefore, the drive source for driving the pushing members 51 to move upward in proportion requires very high control precision. In this embodiment, a pressing mechanism 6 using a motor control method is adopted, and a single pressing mechanism 6 controls a single dispensing assembly 5.

[0037] Refer to the attached Figures 7-9, the pressing mechanism 6 includes a limit frame 60, a pneumatic cylinder 61, a gas guide pipe 62, an alignment member 63, a first guide frame 64, a first spring 65, a servo motor 66, a lead screw 67, and a pressing plate 68. The limit frame 60 is connected to the mounting frame 4. The bottom of the limit frame 60 is connected with a pneumatic cylinder 61. The pneumatic cylinder 61 is a telescopic elastic structure. The bottom of the pneumatic cylinder 61 is connected with a gas guide pipe 62. The gas guide pipe 62 passes through the bottom of the mounting frame 4. The lower part of the mounting frame 4 is also connected with a first guide frame 64. The alignment member 63 is slidably connected to the first guide frame 64. The bottom of the alignment member 63 is connected with the adjacent gas guide pipe 62. The alignment member 63 is docked with the bottom of the storage cylinder 50. A first spring 65 is provided between the alignment member 63 and the first guide frame 64. The servo motor 66 is also fixed to the bottom of the mounting frame 4. A lead screw 67 is connected to the output shaft of the servo motor 66. The top of the lead screw 67 is rotatably connected to the mounting frame 4. The pressing plate 68 is threadedly connected to the lead screw 67. The convex portion on the outside of the pressing plate 68 is slidably connected to the adjacent limit frame 60. The pressing plate 68 is hermetically connected to the top of the adjacent pneumatic cylinder 61.

[0038] The rotation of the output shaft of the servo motor 66 controls the rotation of the lead screw 67. While the lead screw 67 rotates, it controls the up and down movement of the pressing plate 68. When the pressing plate 68 moves downward, the pneumatic cylinder 61 is squeezed and contracted, and the internal air is introduced into the alignment member 63 through the gas guide pipe 62 and is conveyed to the storage cylinder 50 through the alignment member 63, so that the pusher 51 moves upward. When the pusher 51 moves upward, the medicine in the storage cylinder 50 is squeezed. When the pressing plate 68 returns upward, the pneumatic cylinder 61 is restored, and the internal negative pressure, through the cooperation of the gas guide pipe 62 and the alignment member 63, controls the downward movement of the pusher 51 to reset. After the pressing plate 68 is completely reset, the storage cylinder 50 is pressed downward. The bottom of the storage cylinder 50 squeezes the alignment member 63, and the alignment member 63 slides downward to compress the first spring 65. At this time, the top opening of the storage cylinder 50 is separated from the filter valve 52, and then the storage cylinder 50 is taken out of the alignment member 63 to complete the disassembly operation of the storage cylinder 50; then the pusher 51 is moved in the storage cylinder 50, and the residual dregs in the storage cylinder 50 can be cleaned, and it is convenient to clean the inside of the storage cylinder 50 and supplement the medicine. When the alignment member 63 is not under pressure, the first spring 65 is restored. The restoration of the first spring 65 can use the elastic force to keep the alignment member 63 pressing the storage cylinder 50 upward, so that the top of the storage cylinder 50 remains docked with the filter valve 52 and improves the sealing performance during docking.

[0039] In the target medicine, the liquid medicines in different reserve barrels 50 are not necessarily filled in proportion, that is, the reserve barrels 50 are not necessarily consumed synchronously, so it is necessary to take out and replace any consumed reserve barrel 50, and to obtain the amount of liquid medicine in the reserve barrel 50, that is, the liquid height, at any time. In this embodiment, the reserve barrel 50 is made of a transparent material, in order to intuitively display the liquid height of the liquid medicine in the reserve barrel 50, and whether the inner wall is clean when the reserve barrel 50 is cleaned.

[0040] In practice, as described above, the storage tube 50 is made of a transparent material, and the anti-tumor liquid medicine therein may need to be protected from light. At the same time, the anti-tumor Chinese medicine liquid requires strict dust prevention treatment. For this reason, in this embodiment, a shading mechanism 7 is provided outside the storage tube 50 made of a transparent material.

[0041] Reference Figures 10-11 The shading mechanism 7 includes a shading plate 70 pivotally connected to the mounting frame 4. When the shading plate 70 is closed, it forms a closed space with the mounting frame 4, and the mixing component 5 and the pressing mechanism 6 are built in to achieve the shading effect.

[0042] In this embodiment, no matter whether the reserve cylinder 50 is filled with liquid medicine in proportion or filled up at one time, the action of the servo motor 66 needs to be stopped immediately after any reserve cylinder 50 is consumed. As can be seen from the above, the height of the liquid in the reserve cylinder 50 is also directly reflected in the height of the pressing plate 68. As the liquid medicine in the reserve cylinder 50 is consumed, the pressing plate 68 gradually drops. In this embodiment, a trigger mechanism is set on the mounting frame 4. When the liquid medicine in the reserve cylinder 50 is exhausted, the pressing plate 68 drops to the lowest point and triggers the trigger mechanism, which links the shading plate 70 to open, reminding the personnel that the liquid medicine in the reserve cylinder 50 at the opening of the shading plate 70 is currently exhausted and needs to be filled or replaced.

[0043] Specifically, the shading mechanism 7 further includes a first torsion spring 71, a sliding catch 72, a second spring 73 and a pressing member 74; a first torsion spring 71 is provided on the pivot where the shading plate 70 is pivotally connected to the mounting frame 4, and a sliding catch 72 is also slidably connected to the bottom of the mounting frame 4, and the sliding catch 72 includes a hook tongue 721, a slide post 722 connected to the hook tongue and penetrating the mounting frame 4, and a pressure cap 723 connected to the slide post. The sliding catch 72 contacts the shading plate 70, and when the shading plate 70 is closed, the sliding catch 72 radially limits and locks the shading plate 70 to prevent it from opening under the elastic force of the first torsion spring 71. A second spring 73 is provided between the pressure cap 723 and the bottom of the mounting frame 4 and is sleeved outside the slide post 722. A pressing piece 74 is connected to the pressing plate 68, and the pressing piece 74 is squeezed and matched with the sliding clamping piece 72. When the pressing plate 68 moves downward, the pressing piece 74 connected to the pressing plate 68 will also move downward synchronously until it is squeezed with the sliding clamping piece 72, controlling the sliding clamping piece 72 to move downward to compress the second spring 73. After the sliding clamping piece 72 moves downward until the hook tongue 721 loses contact with the shading plate 70, the first torsion spring 71 rebounds to make the shading plate 70 rotate and open, prompting the operator that the medicine inside the reserve cylinder 50 is exhausted and the corresponding reserve cylinder 50 needs to be taken out for cleaning or medicine filling.

[0044] In this embodiment, after the reserve cylinder 50 is filled and before the target medicine is officially prepared, no matter whether the reserve cylinder 50 is filled with liquid medicine in proportion or filled up at one time, there may be gas in the reserve cylinder 50 or in the connecting tube 53. These gases need to be discharged before work. At this time, it is only necessary to start the servo motors 66 one by one to push the liquid medicine to be discharged. When liquid medicine is discharged, it indicates that the connecting tube 53 is full of liquid medicine and the preparation operation can be carried out.

[0045] When the automatic anti-tumor Chinese medicine preparation device of the present invention automatically prepares different anti-tumor Chinese medicine preparations, it is necessary to clean and disinfect the flow channel. Therefore, this embodiment also includes an isolation and disinfection mechanism 8. Figures 12-15 The isolation and disinfection mechanism 8 includes a sliding cover 80, a cover plate 81, a second torsion spring 82, a third spring 83, a constant pressure tube 84 and a pushing frame 85. The sliding cover 80 is slidably connected to the discharge pipe 55, and the cover plate 81 is rotatably connected to the bottom of the sliding cover 80. The cover plate 81 is squeezed and matched with the discharge pipe 55. The cover plate 81 and the sliding cover 80 cooperate to cover and protect the lower half of the discharge pipe 55. A plurality of second torsion springs 82 are connected between the cover plate 81 and the sliding cover 80, a third spring 83 is connected between the top of the sliding cover 80 and the collector tube 54, a constant pressure tube 84 is connected to the front side of the sliding cover 80, and a pushing frame 85 is connected to the lower part of the sliding cover 80.

[0046] The constant pressure tube 84 is connected to a high temperature disinfection device to deliver high temperature disinfection gas to the sliding cover 80, and perform high temperature disinfection on the inside of the flow channel formed by the discharge pipe 55, the sliding cover 80, and the connecting pipe 53. It should also be noted that during the disinfection operation and when the target agent is not prepared, the cover plate 81 always covers the sliding cover 80 for covering protection under the action of the second torsion spring 82. As mentioned above, when the pressing plate 68 is reset upward, the negative pressure generated inside the air cylinder 61 controls the pusher 51 to move downward and reset. At this time, the role of the constant pressure tube 84 is to maintain the flow channel and the external pressure in a straight line, and the negative pressure formed in the air cylinder 61 can make the pusher 51 move downward and reset.

[0047] In this embodiment, the liquid medicines in different storage cylinders 50 need to be injected into the receiving cylinder 93 below after being fully mixed in the confluence cylinder 54. This embodiment is also provided with a guide mechanism 9 to enable the receiving cylinder 93 to be pushed to the bottom of the discharge pipe 55 and the cover plate 81 to be opened in linkage. Figures 15-16 Specifically, the guide mechanism 9 includes a connecting seat 90, a second guide frame 91, a sliding frame 92 and a material receiving barrel 93. The connecting seat 90 is connected to the top of the base 1, and the second guide frame 91 is connected to the top of the connecting seat 90. The sliding frame 92 is slidably connected to the second guide frame 91. The sliding frame 92 is squeezed and matched with the pushing frame 85. The material receiving barrel 93 is clamped on the sliding frame 92. The sliding frame 92 is pushed to control the material receiving barrel 93 to move backward, so that the material receiving barrel 93 moves to the bottom of the discharge pipe 55 to receive the prepared liquid medicine. When the sliding frame 92 moves backward, the sliding frame 92 will contact the inclined surface of the pushing frame 85. When it continues to move backward, it squeezes the pushing frame 85 to make it move upward. The pushing frame 85 moves upward to control the sliding cover 80 to move upward. The sliding cover 80 moves upward to squeeze the cover plate 81 and the discharge pipe 55, thereby turning over. At this time, the second torsion spring 82 twists the discharge pipe 55 to gradually expose it. After the discharge pipe 55 is exposed, the discharge operation can be carried out. After the material receiving barrel 93 completes the material receiving, the sliding frame 92 is released, and the pushing frame 85 loses the squeezing force. At this time, the third spring 83 rebounds, and the sliding cover 80 controls the pushing frame 85 to slide downward. The pushing frame 85 slides downward to push the sliding frame 92 and the material receiving barrel 93 out, making it convenient for the operator to take the material. When the present invention is in use, the reserve cylinder 50 containing the medicament is snapped into the mounting bracket 4. The filter valve 52 at the top of the reserve cylinder 50 is butted against the connecting pipe 53, and the bottom of the reserve cylinder 50 is butted against the alignment member 63. Then, the sliding frame 92 is pushed to control the movement of the receiving cylinder 93 so that the receiving cylinder 93 moves below the discharge pipe 55 to receive the prepared liquid medicament. During the backward movement of the sliding frame 92, the sliding frame 92 will contact the inclined surface of the pushing frame 85. When moving backward continuously, the pushing frame 85 is squeezed to move upward. The upward movement of the pushing frame 85 controls the upward movement of the sliding cover 80. The upward movement of the sliding cover 80 causes the cover plate 81 to be squeezed against the discharge pipe 55, thereby flipping. At this time, the second torsion spring 82 twists and the discharge pipe 55 is gradually exposed. After the discharge pipe 55 is exposed, the discharging operation can be carried out. Then, the servo motor 66 is started. The rotation of the output shaft of the servo motor 66 controls the rotation of the lead screw 67. The rotation of the lead screw 67 controls the downward movement of the pressing plate 68. When the pressing plate 68 moves downward, the air pressure cylinder 61 is squeezed and contracted, and the internal air is introduced into the alignment member 63 through the air guide pipe 62, increasing the internal pressure of the alignment member 63 and delivering it to the reserve cylinder 50 through the alignment member 63, causing the pushing member 51 to move upward. The upward movement of the pushing member 51 squeezes the medicament inside the reserve cylinder 50. The upward movement of the pushing member 51 squeezes the medicament inside the reserve cylinder 50, and cooperates with the filter valve 52 to discharge the liquid component of the medicament inside the reserve cylinder 50 into the connecting pipe 53, and the remaining dregs are collected in the reserve cylinder 50. The liquid medicament is drained into the confluence cylinder 54 through the connecting pipe 53. Since there is a certain pressure when the liquid medicament is squeezed and discharged, a jet phenomenon will occur when the liquid medicament is introduced into the confluence cylinder 54, enabling the liquid medicament to be mixed inside the confluence cylinder 54 and finally discharged into the receiving cylinder 93 through the discharge pipe 55. By controlling the rotation speed of different servo motors 66, it is convenient to control the required dosage of different drugs. And when the pressing plate 68 moves downward, the pressing member 74 connected to the pressing plate 68 will also move downward synchronously. When the pressing member 74 moves downward and squeezes the sliding clamping member 72, it will control the downward movement of the sliding clamping member 72 to compress the second spring 73. After the sliding clamping member 72 moves downward and loses contact with the light-shielding plate 70, the first torsion spring 71 rebounds to rotate and open the light-shielding plate 70, prompting the operator that the medicament inside the reserve cylinder 50 has been used up and the corresponding reserve cylinder 50 needs to be taken out for cleaning or medicament filling and other operations. When the subsequent receiving cylinder 93 finishes receiving the material, the sliding frame 92 is released. At this time, the pushing frame 85 loses the extrusion force, and the third spring 83 rebounds. The sliding cover 80 controls the downward sliding of the pushing frame 85. The downward sliding of the pushing frame 85 pushes the sliding frame 92 together with the receiving cylinder 93 out, facilitating the operator to take the material.After the medicine is exported, the servo motor 66 controls the pressing plate 68 to reset upward through the lead screw 67. When the pressing plate 68 resets upward, the air compression cylinder 61 is restored, and negative pressure is generated inside. Through the cooperation of the air guide pipe 62 and the alignment member 63, the material pushing member 51 is controlled to move downward and reset. After the pressing plate 68 is completely reset, the reserve cylinder 50 is pressed downward. The bottom of the reserve cylinder 50 squeezes the alignment member 63, and the alignment member 63 slides downward to compress the first spring 65. At this time, the filter valve 52 at the top of the reserve cylinder 50 is separated from the connecting pipe 53. Subsequently, the reserve cylinder 50 is taken out from the alignment member 63 to complete the disassembly operation of the reserve cylinder 50. Then, the material pushing member 51 is taken out from the reserve cylinder 50, and the residual medicinal residues inside the reserve cylinder 50 can be cleaned, and it is convenient to clean and supplement the medicine inside the reserve cylinder 50. When the alignment member 63 is not under pressure, the first spring 65 is restored. The restoration of the first spring 65 can use the elastic force to keep the alignment member 63 pressing the reserve cylinder 50 upward, so that the filter valve 52 at the top of the reserve cylinder 50 remains docked with the connecting pipe 53 and improves the sealing performance during docking. Through the above operations, traditional Chinese medicine can be automatically dispensed, and it is convenient to adjust the dosage required for different medicines, improving the convenience and controllability of traditional Chinese medicine dispensing operations, reducing the difficulty of traditional Chinese medicine dispensing, and improving the efficiency of traditional Chinese medicine dispensing.
