Description

Technical Field

[0001] The present invention relates to the technical field of drug mixing ratios, and particularly to a device for mixing and matching tumor treatment drugs. Background Art

[0002] In the medical field, drugs for treating tumors are collectively referred to as anti-tumor drugs. Anti-tumor drugs can be divided into two types: chemotherapy drugs and biological agents. The initial step in the production and preparation process of anti-tumor drugs is to grind and crush solid raw materials, and then mix the ground raw materials strictly according to the formula. Since the flow rate of solid raw materials cannot be calculated, weighing is usually used for proportioning. Multiple raw materials are weighed in sequence, and the weighed raw materials are poured into a mixing tank, and the raw materials are mixed by rotating a stirring shaft.

[0003] Since the mixing tank of the traditional mixing and proportioning device needs to be sealed for mixing, only single-batch raw material mixing can be carried out each time. If raw materials with different proportions need to be mixed, it needs to be carried out in sequence, and double-batch raw material mixing cannot be achieved; in addition, for powdery raw materials, there is an interaction force between raw material particles, and the falling process during material taking is not smooth, and the problem of excessive material taking often occurs, affecting the accuracy of raw material proportioning.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This tumor treatment drug mixing and proportioning device is equipped with an outer mixing tank and an inner mixing tank. The outer mixing motor drives the crank to rotate, the crank drives the base to rotate, and the base drives the inner mixing tank to rotate around the center of the outer mixing tank. At the same time, the inner mixing motor drives the main gear to rotate, the main gear drives the secondary gear to rotate, the secondary gear drives the rotating shaft to rotate, and the top of the rotating shaft drives the inner mixing tank to rotate relative to the base, causing the inner mixing tank to revolve around the center of the outer mixing tank while rotating on its own axis. For the raw materials in the outer mixing tank, the inner mixing tank drives the outer stirring shaft to rotate and revolve to stir and mix the raw materials. For the raw materials in the inner mixing tank, when the inner mixing tank rotates on its own axis, it drives the internal raw materials to rotate relative to the fixed shaft and the inner stirring shaft, so that the raw materials in the inner mixing tank are stirred and mixed by the inner stirring shaft. Moreover, when the inner mixing tank rotates, the internal raw materials are affected by centrifugal force, promoting the rapid mixing of the raw materials. By the rotation and revolution of the inner mixing tank, the raw materials in the inner mixing tank and the outer mixing tank are respectively mixed, achieving the effect of simultaneously mixing two batches of raw materials.

[0016] 2. This tumor treatment drug mixing and proportioning device is equipped with a feeding mechanism. The electric push rod extends to push the receiving cylinder to move upward in the cylindrical groove, so that the top of the receiving cylinder is inserted into the storage cylinder. At this time, the rectangular block is inserted into the inside of the dial block. The rotating motor drives the connecting shaft to rotate, the connecting shaft drives the inner cylinder to rotate relative to the receiving cylinder, so that the inner cylinder drives the dial block to move, the dial block pushes the rectangular block to move, and the rectangular block drives the adjusting plate to rotate around the central column relative to the fixed plate, opening the feeding port.

[0024] Such as Figures 1 to 9As shown in the figure, the tumor treatment drug mixing ratio equipment of this embodiment includes an outer mixing tank 1. An inner mixing tank 2 is arranged inside the outer mixing tank 1. The inner mixing tank 2 and the outer mixing tank 1 are respectively used for mixing two batches of raw materials simultaneously. Both the left and right sides of the outer mixing tank 1 are connected with a central shaft 3. The central shaft 3 penetrates through the frame 4. The outer mixing tank 1 is rotationally connected to the frame 4 through the central shaft 3, so that the outer mixing tank 1 can be turned forward to pour out the processed raw materials inside. On one side of the frame 4 away from the outer mixing tank 1, there is a bracket 5. The bracket 5 is in the shape of a "7". A fixed frame 6 is connected to the top of the bracket 5.

The number of storage cylinders 8 is several, which are used to store a variety of ground solid raw materials. A feeding mechanism 9 is installed at the bottommost part of the inner cavity of the storage cylinder 8. A rodless cylinder 10 is installed between the two fixed frames 6. The actual model of the rodless cylinder 10 is selected according to the actual size between the two fixed frames 6. A ratio receiving mechanism 11 is installed on the front side of the moving part of the rodless cylinder 10, which is used to transfer the raw materials in multiple storage cylinders 8 into the outer mixing tank 1 or the inner mixing tank 2. An elastic baffle 12 is connected between the inner wall of the outer mixing tank 1 and the outer side wall of the inner mixing tank 2. A toothed ring 13 is installed at the inner wall of the outer mixing tank 1 below the elastic baffle 12. The toothed ring 13 is fixed to the inner wall of the outer mixing tank 1; A tank cover 21 is arranged at the top of the inner mixing tank 2. One side of the tank cover 21 is connected to the inner mixing tank 2 by a hinge 22. The tank cover 21 is in the shape of an inverted cone. When the tank cover 21 is closed and raw materials are added to the outer mixing tank 1, the raw materials fall into the inner cavity of the outer mixing tank 1 under the guidance of the side wall of the tank cover 21. An outer stirring shaft 23 is arranged on the outer side wall of the inner mixing tank 2, which is used to stir and mix the raw materials in the outer mixing tank 1. A base 24 is installed at the bottom of the inner mixing tank 2. The center of the lower surface of the base 24 is connected with a crank 25. The bottom end of the crank 25 extends out from the center of the bottom of the outer mixing tank 1 and is connected with an outer mixing motor 27. The actual model of the outer mixing motor 27 is selected according to the actual size of the crank 25. The outer mixing motor 27 is installed at the bottom of the outer mixing tank 1. An outer mixing bearing 26 is installed between the bottom of the crank 25 and the outer mixing tank 1. The top of the crank 25 is connected to the base 24, and the bottom of the crank 25 is connected to the shaft end of the outer mixing motor 27; The upper surface of the base 24 is provided with a clamping rib 241. A main gear 242 is arranged inside the base 24. An internal mixing motor 243 is connected below the main gear 242. The actual model of the internal mixing motor 243 is selected according to the actual size of the main gear 242. A secondary gear 244 is meshed and connected to one side of the main gear 242. A rotating shaft 245 penetrates through the middle of the secondary gear 244. An internal mixing bearing 246 is installed between the bottom of the rotating shaft 245 and the inner wall of the base 24. The top of the rotating shaft 245 is integrally connected to the internal mixing tank 2. The bottom of the rotating shaft 245 is rotatably connected to the base 24 through the internal mixing bearing 246. A through hole 247 is penetrated through the middle of the rotating shaft 245. A fixed shaft 248 penetrates through the inside of the through hole 247. A sealing bearing 249 is installed between the fixed shaft 248 and the inner wall of the internal mixing tank 2. The sealing bearing 249 is used to support the rotational connection between the fixed shaft 248 and the internal mixing tank 2 and seal the gap between the fixed shaft 248 and the internal mixing tank 2. An internal stirring shaft 2410 is connected to the outer side wall of the fixed shaft 248 for stirring and mixing the raw materials in the internal mixing tank 2.

[0025] Specifically, the base 24 is cylindrical. Tooth patterns are provided on both the outer side wall of the base 24 and the inner wall of the tooth ring 13. The base 24 penetrates through the tooth ring 13 and meshes with its inner wall. When the base 24 rotates inside the external mixing tank 1, the base 24 meshes with the tooth ring 13 through the tooth patterns to maintain the rotational stability of the base 24. The bottom of the base 24 is rotatably connected to the external mixing motor 27 through a crank 25. The external mixing motor 27 drives the crank 25 to rotate, the crank 25 drives the base 24 to rotate, and the base 24 drives the internal mixing tank 2 to rotate around the center of the external mixing tank 1, so that the internal mixing tank 2 revolves around the center of the external mixing tank 1 along with the base 24 and drives the external stirring shaft 23 to stir the raw materials in the external mixing tank 1.

[0026] Furthermore, the bottom of the internal mixing tank 2 is clamped to the base 24 through the clamping rib 241. The internal mixing tank 2 can rotate relative to the base 24. The outer side wall of the internal mixing tank 2 is connected to the inner wall of the external mixing tank 1 through an elastic baffle 12. The elastic baffle 12 is in the shape of an elastic rubber ring. Due to the characteristic that the elastic baffle 12 deforms under force, it is convenient for the base 24 to rotate around the axis of the external mixing tank 1 inside the external mixing tank 1. The elastic baffle 12 keeps the raw materials stored in the external mixing tank 1 from leaking. The bottom of the internal mixing tank 2 is integrally connected to the rotating shaft 245. The internal mixing tank 2 is rotatably connected to the base 24 through the rotating shaft 245. The internal mixing motor 243 drives the main gear 242 to rotate, the main gear 242 drives the secondary gear 244 to rotate, the secondary gear 244 drives the rotating shaft 245 to rotate, and the top of the rotating shaft 245 drives the internal mixing tank 2 to rotate relative to the base 24.

[0027] Further, the bottom of the fixed shaft 248 is fixedly welded to the base 24. The fixed shaft 248 passes through the through hole 247 of the rotating shaft 245 and is inserted into the inner mixing tank 2. The fixed shaft 248 is rotationally connected to the inner mixing tank 2 through a sealed bearing 249. When the inner mixing tank 2 rotates relative to the base 24, it drives the internal raw materials to rotate relative to the fixed shaft 248 and the inner stirring shaft 2410, so that the raw materials in the inner mixing tank 2 are stirred and mixed by the inner stirring shaft 2410. For the raw materials in the outer mixing tank 1, they are stirred by the outer stirring shaft 23 when the inner mixing tank 2 rotates self - rotatably, and are also stirred by the outer stirring shaft 23 when the inner mixing tank 2 rotates around the outer mixing tank 1. For the raw materials in the inner mixing tank 2, they are stirred by the inner stirring shaft 2410 when the inner mixing tank 2 rotates self - rotatably, and are also mixed by the centrifugal force generated by the internal raw materials when the inner mixing tank 2 rotates.

[0028] Further, a limiting plate 31 is connected to the side of the middle shaft 3 away from the outer mixing tank 1 to keep the middle shaft 3 connected to the bracket 5.

The screw rod 63 passes through the fixing frame 6 and the clamping column 61 through the jack 62. The screw rod 63 is inserted into the thread groove 72 to form a threaded connection with the cross - plate 7. By rotating the screw rod 63 to screw it out of the thread groove 72, the cross - plate 7 can be pushed to rotate relative to the fixing frame 6, so that the cross - plate 7 is in a horizontal state, and the storage barrel 8 on the cross - plate 7 is flipped from above the outer mixing tank 1 to the rear side position of the outer mixing tank 1, reducing the height of the storage barrel 8, which is convenient for adding raw materials to the storage barrel 8. The function of screwing the screw rod 63 into the thread groove 72 is to fasten between the fixing frame 6 and the cross - plate 7.

The shape of the blanking port 93 is fan-shaped. A regulating plate 94 is sleeved below the fixing plate 91 on the outer side of the central column 92. A central hole 95 is formed through the middle of the regulating plate 94. A rubber ring 96 is arranged on the inner wall of the central hole 95. The rubber ring 96 is used to increase the friction between the inner wall of the central hole 95 and the central column 92, so as to maintain the stability of the pushing block 1110 to push the regulating plate 94 to rotate. A rectangular block 97 is connected to the bottom of the regulating plate 94 near one edge. The fixing plate 91 is welded and fixed to the inner wall of the storage barrel 8. The central column 92 passes through the regulating plate 94 through the central hole 95. The regulating plate 94 is rotationally connected with the central column 92 through the central hole 95. The regulating plate 94 is in the shape of a four-equal-part fan blade, and the regulating plate 94 seals the blanking port 93 below the fixing plate 91. By rotating the regulating plate 94 relative to the fixing plate 91 around the central column 92, the blanking port 93 is opened and closed, and the opening size of the blanking port 93 can be adjusted, so as to adjust the falling speed of the raw materials in the storage barrel 8, and cooperate with the data detected by the pressure sensor 1111 in real time to ensure the accurate proportioning of the raw materials.

[0031] Further, the proportioning material receiving mechanism 11 includes a material receiving frame 111. The material receiving frame 111 is in a U shape. An activity seat 112 is arranged inside the material receiving frame 111. Rotating shafts 113 are connected to both the left and right sides of the activity seat 112.

An inner cylinder 119 is arranged on the inner wall of the material receiving cylinder 117. A dial block 1110 is connected to the inner wall of one side above the inner cylinder 119. A pressure sensor 1111 is installed at the bottommost part of the inner cavity of the inner cylinder 119. The pressure sensor 1111 is electrically connected to the main control center through a circuit to transmit real-time detection data to the main control center. The bottom of the inner cylinder 119 penetrates through the material receiving cylinder 117 and is connected to a connecting shaft 1112.

A groove for installing the rotating motor 1113 is also formed at the bottom of the activity seat 112 to facilitate the up and down movement of the rotating motor 1113 along with the material receiving cylinder 117. Both sides of the activity seat 112 are rotationally connected to the material receiving frame 111 through the rotating shafts 113. The rotating motor 115 drives the rotating shaft 113 to rotate, and the rotating shaft 113 drives the activity seat 112 to flip forward, so that the activity seat 112 drives the material receiving cylinder 117 to flip and discharge materials. The rear side wall of the material receiving frame 111 is installed on the moving part of the rodless cylinder 10. The rodless cylinder 10 is used to drive the material receiving seat to move left and right, so that the material receiving cylinder 117 weighs and transfers the raw materials in multiple storage cylinders 8 in sequence.

[0032] Further, the outer diameter dimension of the material receiving cylinder 117 is adapted to the inner diameter dimension of the cylindrical groove 116. The material receiving cylinder 117 is slidably connected to the inner wall of the cylindrical groove 116. The material receiving cylinder 117 is connected to the telescopic end of the electric push rod 118. When the electric push rod 118 extends, the top of the material receiving cylinder 117 is inserted into the storage cylinder 8. The electric push rod 118 is extended to push the material receiving cylinder 117 to move upward in the cylindrical groove 116, so that the top of the material receiving cylinder 117 is inserted into the storage cylinder 8 to complete the docking, ensuring that no raw materials leak out during the transfer process.

[0033] Furthermore, the bottom of the inner cylinder 119 is integrally connected to the connecting shaft 1112. The inner cylinder 119 is rotationally connected to the material receiving cylinder 117 via the connecting shaft 1112. The dial block 1110 is in a U shape, and the width dimension of the inner wall of the dial block 1110 is adapted to the width dimension of the rectangular block 97. The dial block 1110 is movably inserted into the rectangular block 97. After the top of the material receiving cylinder 117 is inserted into the storage cylinder 8, at this time, the rectangular block 97 is inserted into the interior of the dial block 1110. The connecting shaft 1112 is driven to rotate by the rotary motor 1113. The connecting shaft 1112 drives the inner cylinder 119 to rotate relative to the material receiving cylinder 117, causing the inner cylinder 119 to drive the dial block 1110 to move. The dial block 1110 pushes the rectangular block 97 to move, and the rectangular block 97 drives the adjusting plate 94 to rotate relative to the fixed plate 91 around the central column 92, opening the material discharge port 93.

[0034] The usage method of this embodiment is as follows: When the user actually uses the mixing ratio device to mix the raw materials of the anti-tumor drug, first disassemble and install the screw 51, push the bracket 5 to flip backward around the central axis 3, so that the bracket 5 and the frame 4 are in a perpendicular state to each other, and rotate the screw rod 63 to screw it out of the thread groove 72, push the cross plate 7 to rotate relative to the fixed frame 6, so that the cross plate 7 is in a horizontal state, add a sufficient amount of ground solid raw materials into the plurality of storage barrels 8 from the rear side of the cross plate 7, and then push the bracket 5 and the cross plate 7 to reset, so that the storage barrels 8 are placed above the outer mixing tank 1, rotate the screw rod 63 to screw it into the thread groove 72 for fastening, and then set the ratio of the raw materials in each storage barrel 8 according to the drug formula, turn on the power supply, and start the rodless cylinder 10 to drive the receiving seat to move left and right, so that the receiving seat moves below a certain storage barrel 8, and then the electric push rod 118 extends to push the receiving cylinder 117 to move upward in the cylindrical groove 116, and the top of the receiving cylinder 117 is inserted into the inside of the storage barrel 8. At this time, the rectangular block 97 is inserted into the inside of the dial block 1110, and then the rotary motor 1113 drives the connecting shaft 1112 to rotate, the connecting shaft 1112 drives the inner cylinder 119 to rotate relative to the receiving cylinder 117, so that the inner cylinder 119 drives the dial block 1110 to move, the dial block 1110 pushes the rectangular block 97 to move, and the rectangular block 97 drives the adjusting plate 94 to rotate relative to the fixed plate 91 around the central column 92, so that the material outlet 93 is opened, and the raw materials stored in the storage barrel 8 pass through the material outlet 93 and fall into the inner cylinder 119. The raw materials falling into the inner cylinder 119 fall on the pressure sensor 1111, and the pressure sensor 1111 detects the pressure in real time to obtain the weight of the raw materials. At the same time, the pressure sensor 1111 transmits the detected data to the main control center. When the detected pressure value is close to the preset value, the main control center controls the rotary motor 1113 to reverse, drives the dial block 1110 to drive the adjusting plate 94 to rotate back through the rectangular block 97, and the adjusting plate 94 partially blocks the material outlet 93 to reduce the size of the material outlet 93, slowing down the falling speed of the raw materials in the storage barrel 8. When the detected pressure value reaches the preset value, the main control center controls the rotary motor 1113 to continue to rotate until the adjusting plate 94 completely blocks the material outlet 93, and then the electric push rod 118 contracts to pull the receiving cylinder 117 back into the cylindrical groove 116. The rodless cylinder 10 drives the receiving seat to move left and right, so that the receiving seat is placed above the inner mixing tank 2, and then the turning motor 115 drives the turning shaft 113 to rotate, the turning shaft 113 drives the movable seat 112 to turn forward, so that the movable seat 112 drives the receiving cylinder 117 to turn upside down, and pour the internal raw materials into the inner mixing tank 2. After that, the turning motor 115 rotates back to drive the receiving cylinder 117 to reset, and repeat the above operations to add a variety of raw materials into the inner mixing tank 2 in proportion in turn. Then close the tank cover 21 to complete the addition of the first batch of raw materials. Repeat the above operations to add the second batch of raw materials into the outer mixing tank 1, and then the outer mixing motor 27 drives the crank 25 to rotate, the crank 25 drives the base 24 to rotate, and the base 24 drives the inner mixing tank 2 to rotate around the center of the outer mixing tank 1. At the same time, the inner mixing motor 243 drives the main gear 242 to rotate,The main gear 242 drives the secondary gear 244 to rotate, the secondary gear 244 drives the rotating shaft 245 to rotate, the top of the rotating shaft 245 drives the inner mixing tank 2 to rotate relative to the base 24, so that the inner mixing tank 2 rotates around the center of the outer mixing tank 1 with the base 24 while rotating itself. For the raw materials in the outer mixing tank 1, the inner mixing tank 2 drives the outer stirring shaft 23 to rotate and revolve to stir and mix the raw materials. For the raw materials in the inner mixing tank 2, when the inner mixing tank 2 rotates, it drives the internal raw materials to rotate relative to the fixed shaft 248 and the inner stirring shaft 2410, so that the raw materials in the inner mixing tank 2 are stirred and mixed by the inner stirring shaft 2410. And when the inner mixing tank 2 rotates, the internal raw materials are affected by centrifugal force, which promotes the rapid mixing of the raw materials, enabling the double-batch raw materials to be mixed simultaneously. After the raw materials are mixed, the motor is turned off, and the outer mixing tank 1 is pushed forward so that it flips relative to the frame 4 through the central shaft 3, and the processed raw materials in the outer mixing tank 1 and the inner mixing tank 2 can be poured out.
