Description

Technical Field

[0001] This invention relates to the field of oncology technology, and more specifically, to a novel oncology drug dispensing device. Background Technology

[0002] Oncology is a secondary discipline in clinical medicine, alongside internal medicine and surgery. It is primarily divided into medical oncology, radiation oncology, and surgical oncology. Medical oncology handles the medical treatment of both benign and malignant tumors, radiation oncology focuses on radiation therapy, and surgical oncology primarily involves surgical treatment. Specialized hospitals often further subdivide their departments based on the location of the tumor, such as gastrointestinal oncology and breast surgery.

[0003] According to existing technology, in the preparation of drugs for tumor treatment, multiple drug solutions need to be mixed by a drug preparation device before use. Most existing drug preparation devices use a funnel-shaped mixing container. After the drug solution is mixed, it is discharged through a valve. Since the bottom of the funnel-shaped structure is prone to forming a sedimentation zone, and some drug solution will remain in the valve during opening and closing, and most drug preparation devices are one-piece molded structures, cleaning is inconvenient. As a result, sediment is easy to remain in the container, which can not only cause valve blockage, but also contaminate the drug solution prepared later, affecting the safety of treatment and the effect of drug preparation. Summary of the Invention

[0004] This invention provides a novel oncology medication preparation device that integrates a stirrer and a mixing structure. The stirrer inside the sleeve can directly stir the medication solution. The connecting parts, such as the fixing bolts and nuts, the limiting bolts and the locking blocks, are all detachable. Easily contaminated parts, such as filter plates and filter discs, can be quickly plugged in and replaced, facilitating comprehensive cleaning and disinfection after medication preparation. This solves the problems mentioned in the background art, namely: most medication preparation devices are one-piece molded structures, which are inconvenient to clean and cause sediment to easily remain inside the container, which can not only cause valve blockage but also contaminate the subsequently prepared medication solution, affecting the safety of treatment and the efficacy of medication preparation.

[0005] To achieve the above objectives, a novel oncology drug dispensing device includes a sleeve and a mixing device. The sleeve is threadedly connected to a cover, and a stirrer is fixedly connected to the upper end of the cover. The mixing device is disposed on the surface of the sleeve and includes a receiving cylinder fitted onto the surface of the sleeve. The surfaces of the sleeve and the receiving cylinder are respectively provided with multiple through grooves and drainage grooves. A funnel is threadedly connected to the bottom end of the receiving cylinder. Fixing bolts are inserted into the inner surfaces of the sleeve and the receiving cylinder, and nuts are threadedly connected to the surface of the fixing bolts. A support device is provided directly below the storage tube. The support device includes a pad located at the bottom end of the storage tube and is used to support the storage tube. The surface of the storage cylinder is provided with a crushing device, which includes a fixed frame that is fixedly connected to the surface of the storage cylinder. The crushing device is used to crush the tablets.

[0006] In the above technical solution, the surface of the fixing bolt is fitted with two gaskets, which are respectively located on the surface of the sleeve and the storage cylinder. The surface of the storage cylinder is fixedly connected to two support frames. The side wall of the support frame is rotatably connected to multiple limiting wheels, and two limiting wheels that are close to each other form a group. The upper surface of the pad is fixedly connected to two limiting rods, which are inserted between the two limiting wheels. The limiting rods and the inner surface of the pad are provided with locking blocks. The limiting rods, locking blocks and the inner wall of the pad are threadedly connected to a limiting bolt. The upper surface of the pad and the side wall of the limiting rods are fixedly connected to multiple reinforcing blocks.

[0007] Secondly, the upper end of the storage tube is provided with a limiting device, which includes two support blocks fixedly connected to the upper end of the storage tube. The inner wall of the support block is rotatably connected to a limiting strip, and the surface of the sleeve is fixedly connected to a limiting block. The limiting block is inserted between the support block and the limiting strip. The side wall of the limiting strip is fixedly connected to a compression pad, and the compression pad is located on one side of the limiting block.

[0008] Furthermore, based on the above, the surfaces of the two support frames are provided with a filtering device. The filtering device includes two storage plates fixedly connected to the surfaces of the two support frames. Filter plates are inserted into the inner surfaces of the two storage plates. A top block is fixedly connected to the inner surface of the storage plate. The top block is located on one side of the filter plate. The filter plate is located directly below the funnel. Storage grooves are formed on the surface of the storage plates. The filter plates are inserted into the inner surface of the storage grooves of the storage plates.

[0009] Meanwhile, a sliding rod is slidably connected to the inner wall of the fixed frame, and a placement box is fixedly connected to the surface of the fixed frame. The sliding rod is inserted into the inner surface of the placement box, and a filter disc is inserted into the inner surface of the placement box. Multiple protrusions are fixedly connected to the bottom end of the sliding rod, and two brackets are fixedly connected to the surface of the placement box. Two support wheels are rotatably connected to the bottom end of the brackets, and the support wheels are located directly above the limiting rod.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: This novel oncology dispensing device integrates a stirrer and mixing structure. The stirrer inside the sleeve can directly stir the drug solution. With the design of through grooves and drainage grooves on the surface of the sleeve and the receiving cylinder, the flow path of the drug solution can be adjusted by rotating the receiving cylinder through the relative position of the through grooves and drainage grooves. The surface of the receiving cylinder integrates a crushing device. With the cooperation of the fixing frame, sliding rod, placement box and filter plate, the tablet crushing operation can be completed directly on the dispensing device. The crushed drug powder can be directly entered into the sleeve or introduced into the dispensing process through the funnel after being screened by the filter plate. The sleeve and the cover, the receiving cylinder and the funnel are all connected by threads. The fixing bolts and nuts, the limit bolts and the locking blocks are all detachable structures. The filter plates, filter plates and other easily contaminated parts can be quickly plugged and unplugged for easy cleaning and disinfection after dispensing. Attached Figure Description

[0013] The technical solutions of this invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0014] Because the bottom of the funnel-shaped structure is prone to sedimentation, and some medicine will remain in the valve during opening and closing, and most medicine dispensing devices are one-piece molded structures, making cleaning inconvenient, sediment is easily left inside the container. This can not only cause valve blockage, but also contaminate the medicine to be prepared later, affecting the safety of treatment and the effectiveness of the medicine.

[0015] Therefore, in view of the above-mentioned problems, the present invention provides a novel drug dispensing device for oncology, with reference to... Figure 1-3 As shown, the device includes a sleeve 1 and a mixing device 4. The sleeve 1 is threadedly connected to a cover 2. The threaded connection makes it easy to assemble and disassemble, and facilitates subsequent cleaning and disinfection of the inside of the sleeve 1. The upper end of the cover 2 is fixedly connected to a stirrer 3, which directly stirs the liquid medicine in the sleeve 1 without manual stirring. The mixing device 4 is set on the surface of the sleeve 1. The mixing device 4 includes a receiving cylinder 41 that is fitted on the surface of the sleeve 1. The surfaces of the sleeve 1 and the receiving cylinder 41 are respectively provided with multiple through grooves 42 and drainage grooves 43. By rotating the receiving cylinder 41, the relative positions of the through grooves 42 and the drainage grooves 43 can be adjusted, thereby facilitating the discharge of the liquid medicine in the sleeve 1. The bottom end of the storage cylinder 41 is threadedly connected to a funnel 44. The threaded connection facilitates the disassembly, cleaning, and replacement of the funnel 44. The funnel 44 guides the liquid medicine to be discharged accurately. A fixing bolt 45 is inserted into the inner surface of the sleeve 1 and the storage cylinder 41. A nut 47 is threadedly connected to the surface of the fixing bolt 45. The engagement of the fixing bolt 45 and the nut 47 securely locks the relative positions of the sleeve 1 and the storage cylinder 41, preventing loosening of components during the dispensing process that could affect the mixing effect or cause leakage of the liquid medicine. Two gaskets 46 are fitted onto the surface of the fixing bolt 45, with the two gaskets 46 located on the sleeve... On the surface of the storage tube 41, the gasket 46 enhances the sealing and friction between the fixing bolt 45 and the component, preventing leakage of the medicine from the connection gap and improving the stability of the structural connection. Two support frames 48 are fixedly connected to the surface of the storage tube 41. The support frames 48 provide additional support points for the device and improve the overall structural stability. Multiple limiting wheels 49 are rotatably connected to the side wall of the support frame 48, and two limiting wheels 49 that are close to each other form a group. The limiting wheels 49 can cooperate with the subsequent support structure to achieve precise positioning and smooth adjustment of the storage tube 41.

[0016] refer to Figure 1As shown, a support device 5 is provided directly below the storage cylinder 41 to provide stable support throughout the drug dispensing process and reduce the risk of the equipment tipping over due to a shift in the center of gravity. The support device 5 includes a pad 51 located at the bottom of the storage cylinder 41. Two limiting rods 52 are fixedly connected to the upper surface of the pad 51. The limiting rods 52 are inserted between two limiting wheels 49 to limit the lateral displacement of the storage cylinder 41, so that the storage cylinder 41 can only be adjusted smoothly along the direction of the limiting rods 52. At the same time, the rolling cooperation between the limiting wheels 49 and the limiting rods 52 can reduce friction. The inner surfaces of the limiting rod 52 and the pad 51 are fitted with locking blocks 53. The limiting rod 52, locking blocks 53 and the inner wall of the pad 51 are threaded together with limiting bolts 54. The cooperation of locking blocks 53 and limiting bolts 54 can firmly fix the limiting rod 52 on the pad 51, reducing the loosening or displacement of the limiting rod 52 under force. Multiple reinforcing blocks 55 are fixedly connected to the upper surface of the pad 51 and the side wall of the limiting rod 52. The reinforcing blocks 55 can strengthen the connection strength between the pad 51 and the limiting rod 52, disperse the force at the connection between the two, and reduce the structural deformation caused by long-term load.

[0017] refer to Figure 4 As shown, the upper end of the storage cylinder 41 is provided with a limiting device 6. The limiting device 6 locks the relative position of the sleeve 1 and the storage cylinder 41 to prevent accidental displacement of the two during drug dispensing, thus ensuring the stability of drug dispensing. The limiting device 6 includes two support blocks 61 fixedly connected to the upper end of the storage cylinder 41. The support blocks 61 provide a stable installation base for the entire limiting structure. The inner wall of the support block 61 is rotatably connected to a limiting strip 62. The rotatable design makes the limiting strip 62 flexible to operate, and the limiting or unlocking action can be quickly completed by flipping. A limiting block 63 is fixedly connected to the surface of the sleeve 1. The limiting block 63 is inserted between the support block 61 and the limiting strip 62. The fitting structure can directly limit the circumferential displacement of the sleeve 1 and the storage cylinder 41. A compression pad 64 is fixedly connected to the side wall of the limiting strip 62. The compression pad 64 is located on one side of the limiting block 63. The compression pad 64 fills the gap between the limiting strip 62 and the limiting block 63. The elastic compression enhances the tightness of the fitting between the two and prevents the limiting from loosening due to equipment vibration.

[0018] refer to Figure 5-6 As shown, the surfaces of the two support frames 48 are equipped with a filter device 7 to precisely filter the liquid medicine discharged from the funnel 44, effectively intercepting impurities such as incompletely dissolved medicine residue and powdered medicine residue. The filter device 7 includes two storage plates 71 fixedly connected to the surfaces of the two support frames 48. The storage plates 71 are stably installed by relying on the support frames 48, simplifying the layout of the device. The load-bearing capacity of the support frames 48 ensures structural stability during the filtration process. Filter plates 72 are inserted into the inner surfaces of the two storage plates 71. A top block 73 is fixedly connected to the inner surface of the storage plates 71. The top block 73 is located on one side of the filter plate 72 and fits tightly against one side of the filter plate 72 to limit the lateral movement of the filter plate 72. The filter plate 72 is located directly below the funnel 44, allowing the liquid medicine discharged from the funnel 44 to flow completely through the filter plate 72, reducing leakage during filtration and improving the filtration effect. The surface of the storage plate 71 has a storage groove 74, and the filter plate 72 is inserted into the inner surface of the storage groove 74 of the storage plate 71. The plug-in structure design makes it easy to install and remove the filter plate 72, and medical staff can quickly remove the filter plate 72 for cleaning, disinfection or replacement.

[0019] refer to Figure 7-9 As shown, the surface of the storage cylinder 41 is equipped with a crushing device 8, which is integrated with the main structure of the drug preparation, so that the crushing of tablets and the preparation of drug solution are seamlessly connected. There is no need to carry an additional independent crushing tool, simplifying the drug preparation operation steps in the oncology department. The crushing device 8 includes a fixed frame 81 that is fixedly connected to the surface of the storage cylinder 41. The rigid connection between the fixed frame 81 and the storage cylinder 41 ensures that the overall structure does not shake during the crushing operation, avoiding the decrease in crushing accuracy due to vibration. A sliding rod 82 is slidably connected to the inner wall of the fixed frame 81. The sliding rod 82 is precisely inserted into the inner surface of the placement box 83. This structure allows the sliding rod 82 to be stably raised and lowered along the fixed frame 81. Medical staff can complete the crushing action by pressing down the sliding rod 82. A placement box 83 is fixedly connected to the surface of the fixed frame 81. A slide rod 82 is inserted into the inner surface of the placement box 83. A filter plate 84 is inserted into the inner surface of the placement box 83. The filter plate 84 can screen the pulverized medicine powder and intercept the incompletely crushed medicine particles to ensure that the fineness of the medicine powder entering the dispensing process meets the standard. Multiple protrusions 85 are fixedly connected to the bottom end of the slide rod 82. The protrusions 85 can enhance the squeezing and grinding effect on the medicine tablets and make the medicine tablets pulverized evenly. Two brackets 86 are fixedly connected to the surface of the placement box 83. Two support wheels 87 are rotatably connected to the bottom of the brackets 86. The support wheels 87 are located directly above the limiting rod 52. The brackets 86 and the support wheels 87 form an auxiliary support structure, which can share the force of the crushing device 8 on the storage cylinder 41. At the same time, through the cooperation of the support wheels 87 and the limiting rod 52, the crushing device 8 can be more stable when it adjusts its position synchronously with the storage cylinder 41.

[0020] The working principle of this invention is as follows: The pad 51 of the support device 5 is placed stably on the dispensing table. Through the cooperation of the locking block 53 and the limiting bolt 54, the limiting rod 52 is firmly fixed on the pad 51. The reinforcing block 55 can ensure the connection strength between the two and avoid deformation under subsequent stress. Then, the storage tube 41 is put on the surface of the sleeve 1, so that the limiting wheel 49 on the side wall of the support frame 48 is locked on both sides of the limiting rod 52, thus realizing the initial positioning of the storage tube 41. Simultaneously, insert the fixing bolt 45 into the corresponding hole of the sleeve 1 and the storage cylinder 41, put on the gasket 46 and tighten the nut 47. The gasket 46 enhances the sealing and friction to prevent the medicine from leaking and the parts from loosening. Finally, flip the limiting strip 62 on the inner wall of the support block 61 at the upper end of the storage cylinder 41 so that the limiting block 63 on the surface of the sleeve 1 is fitted between the support block 61 and the limiting strip 62. The squeezing pad 64 fills the gap and squeezes elastically to further lock the relative position of the sleeve 1 and the storage cylinder 41 to prevent the medicine from shifting during dispensing. Insert the filter plate 72 into the storage groove 74 of the storage plate 71 on the surface of the two support frames 48. The top block 73 inside the storage plate 71 is close to one side of the filter plate 72 to limit the filter plate 72 laterally, ensuring that the filter plate 72 is located directly below the funnel 44 at the bottom of the storage cylinder 41, in preparation for subsequent filtration of the medicine. Then insert the filter disc 84 into the placement box 83 of the crushing device 8. The placement box 83 is fixed to the surface of the storage cylinder 41 by the fixing frame 81. The support wheel 87 at the bottom of the bracket 86 rests directly above the limiting rod 52, which not only shares the force on the crushing device 8, but also ensures its stability when it is adjusted with the storage cylinder 41. When it is necessary to prepare a liquid medicine from solid tablets, open the placement box 83 of the crushing device 8, put the tablets into the filter plate 84, and then close the lid of the placement box 83. Medical staff press down the slide bar 82 by hand. The slide bar 82 moves up and down steadily along the inner wall of the fixed frame 81. Multiple protrusions 85 at its bottom end squeeze and grind the tablets in the filter plate 84. The protrusions 85 can enhance the crushing effect and ensure that the tablets are crushed evenly. During the crushing process, the tablet particles that are not completely crushed will be intercepted by the filter plate 84. The powder that meets the fineness requirements will fall into the bottom of the placement box 83 through the filter plate 84. Medical staff can open the placement box 83 and pour the screened powder into the sleeve 1 to achieve seamless connection between tablet crushing and medicine preparation without the need for additional independent crushing tools. Add solvent into sleeve 1, tighten sleeve cap 2 connected to the thread on the surface of sleeve 1. Sleeve cap 2 is easy to install and remove, and is also easy to clean and disinfect later. Start the stirrer 3 at the top of sleeve cap 2. Stirrer 3 directly stirs the powder and solvent in sleeve 1 without manual operation. This can improve mixing efficiency and ensure that the drug solution is mixed evenly, meeting the needs of precise drug preparation in the oncology department. After mixing, if it is necessary to drain the liquid, loosen the nut 47 on the fixing bolt 45 and slowly rotate the collection cylinder 41. Since the collection cylinder 41 is connected to the limiting rod 52 through the limiting wheel 49, the friction is small and the adjustment is smooth during rotation. During the rotation, the relative position of the through groove 42 on the surface of the sleeve 1 and the drain groove 43 on the surface of the collection cylinder 41 can be adjusted. When the through groove 42 and the drain groove 43 are aligned, the liquid in the sleeve 1 enters the collection cylinder 41 through the through groove 42, and is then guided by the funnel 44 threaded at the bottom of the collection cylinder 41 to flow precisely to the filter plate 72 below. The funnel 44 is threaded, which facilitates disassembly, cleaning and replacement, and avoids liquid residue contamination. When the medicine flows through the filter plate 72, impurities such as undissolved medicine residue and pulverized residue will be intercepted by the filter plate 72. The filtered clean medicine will be collected in the medicine preparation container below through the filter plate 72, ensuring that the medicine entering the patient's body is free of impurities and improving the safety of medication. After the medication is prepared, first unscrew the funnel 44 at the bottom of the storage cylinder 41 and clean and disinfect the funnel 44 separately; then pull out the filter plate 72 in the storage plate 71 and the filter disc 84 in the crushing device 8 placement box 83, and clean or replace them respectively to prevent cross-contamination of different medications; then loosen the nut 47 and the limiting strip 62 of the fixing bolt 45 to separate the sleeve 1 from the storage cylinder 41, and after removing the cover 2, thoroughly clean and disinfect the inside of the sleeve 1 and the stirrer 3. All parts are easy to disassemble and assemble, with no complicated hidden corners, which makes it easy for medical staff to complete the cleaning work efficiently and prepare for the next medication preparation.
