Description

Technical Field

[0001] The invention relates to the technical field of tumor experimental drugs, in particular to a tumor experimental drug configuration and mixing device. Background Art

[0002] In cancer treatment, experimental drug combination refers to combining experimental drugs with existing treatments (such as chemotherapy, radiotherapy, immunotherapy, etc.) to improve the treatment effect or overcome the limiting factors in treatment. This strategy aims to improve the effectiveness of cancer treatment by enhancing the efficacy of drugs, reducing drug resistance and side effects, and improving patient prognosis.

[0003] Generally speaking, in order to inject therapeutic drugs into patients for treatment, the therapeutic drugs must be liquid in nature. If they are powdered drugs, they must be mixed with distilled water before injection. The current drug mixers mix powdered drugs and distilled water ampoules through bilateral combination. However, the problem with this is that when distilled water is injected into the powdered drug ampoule, bubbles will be generated and the distilled water and drugs cannot be mixed well.

[0004] In order to solve the problems that occur when the above-mentioned drug mixer is used, the existing Chinese patent document CN202311254629.4 discloses a mixing device for preparing tumor experimental drugs, which provides a placement cover and combines two placement covers to combine and mix the powdered medicine ampoule bottle and the distilled water ampoule bottle, and through holes are set on the first puncture needle, the connecting column, and the second puncture needle. A valve is installed on the through hole. When the valve is installed on the through hole, the distilled water is discharged only on one side, so that when the distilled water ampoule bottle is located on the upper side, the distilled water is discharged, and when the powdered medicine ampoule bottle is located on the upper side, the mixed medicine liquid is prevented from flowing back; Although the mixing device in the above scheme can achieve the mixing of distilled water and medicine, after a group of powdered medicine ampoules and distilled water ampoules are combined and mixed, it is necessary to remove the stopper in the threaded tube and connect the syringe to the threaded tube to discharge the mixed medicine contained in the powdered medicine ampoule through the threaded tube. After the discharge, the powdered medicine ampoule and distilled water ampoule placed in the cover are removed and replaced with new powdered medicine ampoule and distilled water ampoule before continuing the drug mixing work. This will undoubtedly slow down the progress of tumor experiment drug configuration, resulting in poor efficiency of tumor experiment drug configuration, and it is difficult to meet the high-intensity drug configuration needs.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figure 1 and Figure 2 The device for mixing and disposing tumor experimental drugs shown in the figure comprises a bottom plate 1 and a pair of disposing boxes 2, wherein the pair of disposing boxes 2 are connected by a connecting plate, and the connecting plate is connected to the bottom plate 1 by a connecting frame; the device also comprises: a limit bracket 3 fixed on the disposing box 2, a rotating shaft 4 inserted downwardly into the disposing box 2 is rotatably installed in the middle of the limit bracket 3, a stirring blade 5 is fixedly installed on the lower part of the rotating shaft 4 located in the disposing box 2, a first rotating gear 6 is fixedly sleeved on the outer side of the rotating shaft 4, a driving unit 7 is arranged between the two first rotating gears 6, a power switching unit 8 is arranged on the outer side between the two disposing boxes 2, and the upper part of the power switching unit 8 is connected to the driving unit 7, An L-shaped tube 9 with a rubber stopper is fixedly installed at the lower part of the two configuration boxes 2, a butterfly valve 10 is installed on the L-shaped tube 9, and the lower part of the power switching unit 8 is connected to the two butterfly valves 10 respectively; two No. 1 supports 11 are fixed to the upper part of the rotating shaft 4 in a horizontal direction and are symmetrically distributed, and a placement unit 12 is rotatably installed at one end of the No. 1 support 11, and two groups of mixing mechanisms 13 are installed outside the rotating shaft 4 between the stirring blade 5 and the placement unit 12, and the two groups of mixing mechanisms 13 are axially symmetrically distributed about the axis of the rotating shaft 4; a distilled water tank 14 is located directly above the No. 1 rotating gear 6 and fixedly connected to the rotating shaft 4, and a spraying unit 15 is installed at the lower part of the distilled water tank 14.

In this process, the power switching unit 8 is used to move the driving unit 7 to another configuration box 2, and the other configuration box 2 continues to perform the configuration work, so that the two configuration boxes 2 alternately mix and configure the medicine. This means that in the same time, researchers can complete more drug configuration tasks, thereby accelerating the experimental process and shortening the new drug research and development cycle.

[0024] For further information, see Figure 4 , Figure 5 The power switching unit 8 includes a T-shaped plate 24 arranged between the two configuration boxes 2, a threaded column 25 is threadedly connected to the T-shaped plate 24, and both ends of the threaded column 25 are fixed with a limit shaft 26, one of the limit shafts 26 is rotatably connected to the connecting plate between the two configuration boxes 2 through a bearing, and the other limit shaft 26 is rotatably connected to an L-shaped plate 27 through a bearing, the bottom of the L-shaped plate 27 is fixed on the bottom plate 1, and one end of the limit shaft 26 is fixedly connected to a hand wheel 28, and both ends of the bottom of the T-shaped plate 24 are fixed with a No. 1 rack 29, and the outer side of the valve stem of the butterfly valve 10 is fixedly sleeved with a No. 2 rotating gear 30 meshing with the No. 1 rack 29, and the top of the T-shaped plate 24 is rotatably connected to a push rod 31, and the end of the push rod 31 away from the T-shaped plate 24 is rotatably connected to the bottom of the No. 1 U-shaped plate 16; Among them, see Fig.10 In order to make the driving unit 7 more stable when moving horizontally, the limiting member 23 includes two light rods 51 fixed on the outside of the limiting bracket 3, the outer side of the light rod 51 is slidably sleeved with a sliding sleeve 52, the outer side of the sliding sleeve 52 is fixedly sleeved with a connecting frame 53, and two No. 3 U-shaped plates 54 are symmetrically fixed at the middle position of the bottom of the connecting frame 53, and the No. 3 U-shaped plate 54 is fixedly connected to the No. 2 U-shaped plate 19 located at the upper part.

[0025] The principle of the power switching unit 8 driving the driving unit 7 to move: when one of the configuration boxes 2 completes the configuration work, the hand wheel 28 is manually rotated, and the hand wheel 28 drives the limit shaft 26 and the threaded column 25 to rotate, and the threaded column 25 drives the T-shaped plate 24 to move, and the top of the T-shaped plate 24 drives the push rod 31 to rotate, and one end of the push rod 31 drives the No. 1 U-shaped plate 16 to move horizontally under the drive of the limit member 23, so that the driving motor 17, the driving gear 18 and the transmission gear 22 move horizontally, so that the transmission gear 22 on one side is disengaged from one of the No. 1 rotating gears 6, and the transmission gear 22 on the other side moves to mesh with the No. 1 rotating gear 6 on the other configuration box 2, so as to realize the other side. The connection transmission between the No. 1 rotating gear 6 and the driving unit 7 enables the configuration box 2 on this side to start stirring, and when the connecting frame 53 above the driving unit 7 slides on the outside of the light rod 51, the No. 1 rack 29 at the bottom of the T-plate 24 moves and drives the No. 2 rotating gear 30 to rotate, driving the valve stem of the butterfly valve 10 to rotate a certain angle. Since the butterfly valves 10 on both sides are symmetrically distributed, the synchronous rotation of the valve stems of the butterfly valves 10 on both sides can open the butterfly valve 10 on this side and close the butterfly valve 10 on the other side. The configuration box 2 on the side where the butterfly valve 10 is opened completes the configuration task and performs the injection work, and the bottom of the configuration box 2 on the side where the butterfly valve 10 is closed is closed and starts automatic configuration work.

[0026] Example 2: Please refer to Figure 6 , Figure 7 and Fig. 9 This embodiment further explains the first embodiment, and the difference is that the work of adding powdered medicine is optimized.

[0027] Specifically, the two placement units 12 include a semicircular shell 32 rotatably mounted on one end of the No. 1 support 11 and placed obliquely downward, and a telescopic member 33 rotatably mounted on the outer side of the rotating shaft 4, a baffle 34 is fixed to the lower part of the semicircular shell 32, and a through hole is opened on the baffle 34, the telescopic member 33 is arranged obliquely, and the upper end of the telescopic member 33 is rotatably connected to the lower part of the semicircular shell 32; the telescopic member 33 includes a connecting seat 35 fixedly sleeved with the outer side of the rotating shaft 4, both sides of the connecting seat 35 are fixedly connected with the No. 2 support 36, one end of the No. 2 support 36 is rotatably connected with a spring seat 37, a telescopic rod 38 is fixed to the end of the spring seat 37 away from the No. 2 support 36, a circular plate 39 is fixed to the end of the telescopic rod 38 away from the spring seat 37, the circular plate 39 is rotatably connected to the lower part of the semicircular shell 32, a return spring 40 is sleeved on the outside of the telescopic rod 38, and the two ends of the return spring 40 are respectively fixedly connected to the spring seat 37 and the circular plate 39; At the same time, in order to further stir and mix the materials in the configuration box 2, the mixing mechanism 13 includes a No. 2 rack 41 vertically welded to the outer surface of the rotating shaft 4, a No. 3 rotating gear 42 is meshed on one side of the No. 2 rack 41, a rotating rod 43 is fixedly sleeved in the middle of the No. 3 rotating gear 42, the outer side of the rotating rod 43 is rotatably connected to a limit block 44 through a bearing, a movable rod 45 is hinged at one end of the limit block 44, the upper part of the movable rod 45 is rotatably connected to the bottom of the spring seat 37, and a plurality of auxiliary stirring rods 46 are fixedly installed on the outside of the rotating rod 43.

[0028] In addition, in order to make the third rotating gear 42 more stable and not shake when moving, a sliding pin 57 is fixed to one end of the limit block 44, and a sliding groove matched with the sliding pin 57 is opened on the second rack 41.

[0029] It should be noted that: the powdered medicine ampoule bottle with the rubber stopper removed is placed in the semicircular shell 32. At this time, the semicircular shell 32 can be pressed to rotate downward under the pressure of the powdered medicine ampoule bottle, so that the semicircular shell 32 and the lower part of the powdered medicine ampoule bottle are deflected downward. At this time, the telescopic rod 38 and the return spring 40 are also compressed. After the powdered medicine ampoule bottle is placed, the rotating shaft 4 directly drives the powdered medicine ampoule bottle to revolve. At this time, the powdered medicine ampoule bottle is rotated under the action of gravity. The medicine powder in the ampoule can be slowly thrown into the configuration box 2 through the inclined semicircular shell 32, and the powder can be rotated while being thrown, so as to further improve the uniformity of the medicine powder feeding. As the powder in the ampoule of powdered medicine becomes less and less, its own weight will also become smaller and smaller. Therefore, during this process, the return spring 40 can slowly rebound to its original shape, thereby pushing the ampoule of powdered medicine and the semicircular shell 32 to slowly rotate upward and reset, so as to ensure the uniformity of the powder when being sprinkled into the configuration box 2. At the same time, it is worth noting that when the ampoule bottle of the powdered medicine is pressed and drives the telescopic part 33 to rotate downward, it will also drive the movable rod 45 to rotate upward around the No. 2 support 36 at its lower end to a certain angle, thereby driving the No. 3 rotating gear 42 to move. Since the No. 3 rotating gear 42 is meshed with the No. 2 rack 41, it will rotate while moving, thereby driving multiple auxiliary stirring rods 46 to stir and rotate the powdered medicine from top to bottom, and further stir and mix the materials in the configuration box 2.

[0030] Example 3: Please refer to Figure 2 and Figure 8 This embodiment further illustrates other embodiments, the difference being that the work of adding distilled water is optimized.

[0031] Specifically, the spraying unit 15 includes a support plate 47 fixed to the outside of the rotating shaft 4 and located between the two groups of placement units 12, a micro pump 48 is installed on the support plate 47, a spray pipe 49 is fixedly connected to the bottom of the support plate 47, and a plurality of nozzles 50 evenly distributed in a straight line are fixedly connected to the bottom of the spray pipe 49, the output end of the micro pump 48 is connected to the spray pipe 49 through a pipeline, and the input end of the micro pump 48 is connected to the distilled water tank 14 through a pipeline. In the process of mixing and configuring, by starting the micro pump 48, the micro pump 48 draws out the distilled water inside the distilled water tank 14 and introduces it into the spray pipe 49, and finally sprays water into the configuration box 2 from the plurality of nozzles 50. The sprayed distilled water can be evenly sprayed when the powdered medicine is sprinkled in to achieve the purpose of uniform mixing and stirring.

[0032] Meanwhile, it is worth noting that a water injection pipe 55 is fixedly connected to the top of the distilled water tank 14 , and a sealing plug 56 is threadedly connected to the top of the water injection pipe 55 , so that it is convenient to open the sealing plug 56 to add distilled water into the distilled water tank 14 .

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
