Description

Technical Field

[0001] The present invention relates to the technical field of decoction preparation, and more specifically, it relates to a preparation machine, formula and preparation process for activating blood circulation, dredging collaterals, benefiting the lungs and removing stasis decoction. Background Art

[0002] Acute lung injury is a diffuse lung parenchymal injury caused by various intrapulmonary and extrapulmonary factors (such as severe infection, sepsis, trauma, inhalation injury, etc.). Clinically, it is mainly manifested as hypoxemia, decreased lung compliance, pulmonary edema and out-of-control inflammatory response. Further development of ALI can evolve into acute respiratory distress syndrome (ARDS), with a high mortality rate, seriously threatening the lives of patients. At present, the clinical treatment of ALI / ARDS still mainly focuses on mechanical ventilation, fluid management, anti-infection and supportive treatment, and there is still a lack of specific therapeutic drugs. Although anti-inflammatory drugs such as glucocorticoids can reduce the inflammatory response, they have obvious adverse reactions such as immunosuppression, secondary infection, and increased blood sugar, and their application is limited.

[0003] At present, when using traditional Chinese medicine to treat acute lung injury in the market, a decocting device is needed to decoct the traditional Chinese medicine to obtain a decoction filtrate that is convenient for separation for treating patients. However, when the current decocting device is used, it requires staff to manually put the non-woven medicine bag containing medicinal materials into the device. After the medicinal materials are decocted, it requires staff to manually extract the filter cylinder and use tools to squeeze the medicine bag to squeeze out the excess medicinal liquid, which increases the labor intensity of the staff to a certain extent and prolongs the processing time of the device for medicinal materials to a certain extent. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a preparation machine, formula and preparation process for activating blood circulation, dredging collaterals, benefiting the lungs and removing stasis decoction.

[0005] To achieve the above purpose, the present invention provides the following technical solutions: A preparation machine for activating blood circulation, dredging collaterals, benefiting the lungs and removing stasis decoction, including a device body. There is a decocting barrel on the top of the device body, and a control panel is arranged on one side of the device body. Inside the decocting barrel on the top of the device body, there is a filter cylinder with mesh holes opened on it. A cross-shaped support frame is fixedly connected to the top of the device body. There is a lifting groove opened on one side of the vertical rod of the cross-shaped support frame. Inside the lifting groove, there is a lifting frame that extends outside the lifting groove. The cross-section of the lifting frame is in the shape of a dry character. Inside the lifting frame, there are two symmetrical support fixing frames fixedly connected. The cross-section of the support fixing frame is in the shape of a C. The bottom of the support fixing frame is fixedly connected with a top cover, and a power moving groove is opened inside the top cover; The power moving trough is equipped with a connecting and stabilizing mechanism for connecting and fixing the filter cartridge. A third motor is fixedly connected to the top of the support frame. The output end of the third motor rotates through the top of the support frame and extends into the interior of the support frame. A transmission connecting rod is fixedly connected to the output end of the third motor. A stirring and pressing mechanism for pressing the Chinese medicine non-woven fabric medicine pack inside the filter cartridge is provided at the bottom of the transmission connecting rod. An adjustment groove is opened on one side of the cross-shaped support frame horizontal rod and is located below the lifting trough. A positioning and fastening mechanism for clamping and fixing the filter cartridge is provided inside the adjustment groove.

[0006] A formula for a blood-activating, meridian-clearing, lung-benefiting, and blood-stasis-removing decoction, each serving includes 30g of Astragalus membranaceus, 20g of Salvia miltiorrhiza, 10g of Ginseng, and 15g of Ligusticum chuanxiong.

[0007] A preparation process for a blood-activating, meridian-clearing, lung-benefiting, and stasis-removing decoction includes the following specific steps: S1. Pre-treatment of medicinal materials: Astragalus membranaceus: remove impurities, wash, and cut into thick slices; Salvia miltiorrhiza: remove impurities, wash, and cut into thick slices; Ginseng: remove impurities, wash, and cut into thin slices; Ligusticum chuanxiong: remove impurities, wash, and cut into thick slices; S2. Soaking: Mix the four medicinal herbs, add 8-12 times the total weight of the herbs in purified water, and soak at room temperature for 30-60 minutes to allow the herbs to fully absorb water and swell. S3, Decoction and Extraction: After soaking the medicinal materials, put them into the filter cartridge and inject external water into the equipment body through the external pipe. The staff then uses the control panel. S4. The staff starts the equipment through the control panel, heats the water to boiling point 100℃, maintains a gentle boil for 45-60 minutes, and presses the medicine bag with the pressure plate to immerse the medicine bag in the water inside the equipment, so that the water can completely soak the medicine and the medicine can be decocted more smoothly. S5. After the medicinal herbs have been decocted, the staff removes the filter cylinder through the control panel and squeezes out the remaining liquid in the medicine bag using the pressure plate to obtain the blood-activating, meridian-clearing, lung-benefiting, and stasis-removing decoction.

[0008] The advantages of this invention are: 1. This invention relates to a preparation machine, formula, and preparation process for a blood-activating, meridian-clearing, lung-benefiting, and stasis-removing decoction. By resetting the first spring, the mounting frame slides into the interior of the mounting groove, thereby connecting and fixing the displacement plate and the rotating disk, and switching modes. This allows the rotating disk and the displacement plate to move downward under the drive of the transmission connecting rod, and the pressure plate moves downward through the pressure rod to press the medicine pack, causing the medicine liquid to drain out, thereby improving the utilization rate of the medicine liquid.

[0009] 2. The present invention provides a preparation machine, formula, and preparation process for a blood-activating, meridian-clearing, lung-benefiting, and stasis-removing decoction. By realizing the transmission circular plate pushing the moving circular plate to different height positions, the moving circular plate drives the hinged connecting rod to move downward, causing the rotating rod to drive the first and second gripping plates to rotate to different angles. This allows the first and second gripping plates to grasp the medicine packs at different closing sizes, making it more convenient for workers to use the device.

[0010] 3. The present invention provides a preparation machine, formula, and preparation process for a blood-activating, meridian-clearing, lung-benefiting, and stasis-removing decoction. By moving a circular plate, the hinged connecting rod moves upward, causing the rotating rod to rotate the first and second gripping plates. This releases the gripping of the medicine pack by the multiple second gripping plates, allowing the worker to retrieve the medicine pack from the air. This makes the retrieval of the medicine pack smoother, reduces the labor intensity of the workers to a certain extent, and makes it more convenient for the workers to use the device.

[0011] 4. The present invention provides a blood-activating, meridian-clearing, lung-benefiting, and stasis-removing decoction preparation machine, formula, and preparation process. When the first and second gripping plates are in a vertical state, the square rod drives the rotating column, the extended connecting rod, and the pressure plate to rotate, thereby disturbing the medicine pack. The first and second gripping plates can act as stirring rods to stir the liquid medicine, so that the medicinal materials can be fully decocted. Attached Figure Description

A lifting groove 3 is provided on one side of the vertical rod of the T-shaped support frame 2. A lifting frame 6 extending to the outside of the lifting groove 3 is slidably connected inside the lifting groove 3. The cross-section of the lifting frame 6 is T-shaped. Two symmetrical support fixing frames 17 are fixedly connected inside the lifting frame 6. The cross-section of the support fixing frames 17 is C-shaped. The two support fixing frames 17 are provided with the same structure. A top cover 16 is fixedly connected to the bottom of the support fixing frame 17. The top cover 16 can be sealed and fitted with the decoction barrel when the medicine is boiled. A heating mechanism is provided at the bottom of the decoction barrel. The heating mechanism can be a heating rod or other heating structure.

[0016] The top cover 16 can seal the main body of the equipment, allowing the main body of the equipment to more smoothly decoct the Chinese medicine inside the filter cartridge 15.

[0017] Please see Figure 1-4 The top cover 16 has a power moving groove 69 inside, and the power moving groove 69 is equipped with a connection and stabilizing mechanism for connecting and fixing the filter cartridge 15. The top of the support frame 17 is fixedly connected to a third motor 18. The third motor 18 is an existing structure and will not be explained in detail here. The output end of the third motor 18 rotates through the top of the support frame 17 and extends into the interior of the support frame 17. The output end of the third motor 18 is fixedly connected to a transmission connecting rod 19. The bottom of the transmission connecting rod 19 is equipped with a stirring and pressing mechanism for pressing the Chinese medicine non-woven fabric medicine pack inside the filter cartridge 15. The cross-shaped support frame 2 has an adjustment groove 8 on one side of the horizontal rod, which is located below the lifting groove 3. The adjustment groove 8 is equipped with a positioning and fastening mechanism for clamping and fixing the filter cartridge 15.

[0018] The lifting trough 3 is internally connected to a first threaded rod 4 that is threaded to the lifting frame 6. The top of the cross-shaped support frame 2 is fixedly connected to a first motor 5. The first motor 5 is an existing structure and will not be explained in detail here. The output end of the first motor 5 rotates through the top of the cross-shaped support frame 2 and extends into the interior of the lifting trough 3. The output end of the first motor 5 is fixedly connected to the top of the first threaded rod 4. The operator can start the first motor 5 through the control panel and make the first motor 5 drive the first threaded rod 4 to rotate forward and backward, so that the lifting frame 6 can move up and down. The top cover 16 is equipped with an exhaust valve. The exhaust valve is an existing structure and will not be explained in detail here. It can exhaust the hot air inside the equipment body 1.

[0019] Example 2, please refer to Figure 5-6 The connecting and stabilizing mechanism includes a second connecting support plate 68 and a first connecting support plate 66. The surfaces of the first connecting support plate 66 and the second connecting support plate 68 are slidably connected to the interior of the power moving groove 69. The first connecting support plate 66 and the second connecting support plate 68 are symmetrically arranged on both sides inside the power moving groove 69. The cross-section of the first connecting support plate 66 and the second connecting support plate 68 is U-shaped. The bottom end of the top cover 16 is provided with two power sliding grooves 70 that communicate with the interior of the power moving groove 69. The surfaces of the first connecting support plate 66 and the second connecting support plate 68 are slidably connected to the interior of the power sliding grooves 70. The bottom of the first connecting support plate 66 and the second connecting support plate 68 are respectively fixedly connected with connecting fixing rods 65. The filter cartridge 15 is provided with connecting and stabilizing holes 64 that are inserted into the surface of the connecting fixing rods 65.

[0020] The connecting rod 65 can slide into and out of the connecting and stabilizing hole 64, and realize the connection and separation of the filter cartridge 15 and the top cover 16. Two symmetrical transmission release rods 67 are fixedly connected to the side of the first connecting support plate 66 away from the second connecting support plate 68. By pushing the transmission release rods 67, the first connecting support plate 66 and the connecting rod 65 can be moved.

[0021] Please see Figure 5An L-shaped power transmission frame 73 is fixedly connected to the surface of the transmission release rod 67 and slidably connected to the inside of the power movement groove 69. A power transmission plate 71 is fixedly connected to the surface of the second connecting support plate 68 and slidably connected to the inside of the power movement groove 69. A second gear 72 is rotatably connected inside the power movement groove 69 and is disposed between the L-shaped power transmission frame 73 and the power transmission plate 71. Both the power transmission plate 71 and the L-shaped power transmission frame 73 are provided with teeth on the side near the second gear 72. The power transmission plate 71 and the L-shaped power transmission frame 73 are connected to the surface of the second gear 72 through the teeth. Thus, the power transmission plate 71 and the L-shaped power transmission frame 73 can move relative to each other by rotating the second gear 72. A third motor 20 is fixedly connected to the top of the top cover 16. The output end of the third motor 20 rotatably penetrates into the inside of the power movement groove 69. The output end of the third motor 20 is fixedly connected to the top of the second gear 72.

[0022] Example 3, please refer to Figure 5-6 The positioning and fastening mechanism includes a second bidirectional threaded rod 9. One end of the second bidirectional threaded rod 9 is rotatably connected to the inner wall of one end of the cross support frame 2. The other end of the second bidirectional threaded rod 9 is fixedly connected to a first bidirectional threaded rod 7. Both the first bidirectional threaded rod 7 and the second bidirectional threaded rod 9 are provided with two opposite threads. A second motor 14 is fixedly connected to one side of the cross support frame 2. The output end of the second motor 14 rotatably passes through the other end of the cross support frame 2 and extends into the interior of the adjusting groove 8. The output end of the second motor 14 is fixedly connected to the other end of the first bidirectional threaded rod 7. The operator can start the second motor 14 through the control panel, which can drive the first bidirectional threaded rod 7 and the second bidirectional threaded rod 9 to rotate.

[0023] Please see Figure 6 The surfaces of the first bidirectional threaded rod 7 and the second bidirectional threaded rod 9 are threadedly connected to the first clamping plate 10 and the second clamping plate 11. The first clamping plate 10 and the second clamping plate 11 on the first bidirectional threaded rod 7 are respectively set on two opposite threads on the first bidirectional threaded rod 7. The first clamping plate 10 and the second clamping plate 11 on the second bidirectional threaded rod 9 are respectively set on two opposite threads on the second bidirectional threaded rod 9. Thus, when the second motor 14 drives the first bidirectional threaded rod 7 and the second bidirectional threaded rod 9 to rotate, the first clamping plate 10 and the second clamping plate 11 can move relative to each other. The surfaces of the first clamping plate 10 and the second clamping plate 11 are slidably connected to the inside of the adjusting groove 8. The top of the first clamping plate 10 and the second clamping plate 11 are both provided with arc-shaped grooves for supporting and clamping the filter cartridge 15. The top of the first clamping plate 10 and the second clamping plate 11 are both fixedly connected to the backflow arc plate 13 for guiding the liquid medicine.

[0024] After the filter cartridge 15 moves to the top of the first clamping plate 10 and the second clamping plate 11, the first clamping plate 10 and the second clamping plate 11 move relative to each other, which can position and clamp the filter cartridge 15 through the arc groove, and make the filter cartridge 15 more smoothly drain the medicine inside the filter cartridge 15, thereby improving the utilization rate of the medicine.

[0025] In use, the third motor 20 is started, causing the second gear 72 to rotate. This causes the second gear 72 to move the second connecting support plate 68 through the power transmission plate 71, and the connecting fixing rod 65 to slide out of the connecting stabilizing hole 64, separating the filter cartridge 15 and the top cover 16. The movement of the first clamping plate 10 and the second clamping plate 11 allows the first clamping plate 10 and the second clamping plate 11 to clamp and fix the filter cartridge 15 more stably through the arc groove, and allows the device to control the top cover 16 to continue moving upward more smoothly.

[0026] Example 4, please refer to Figure 7-12 The stirring and pressing mechanism includes a square rod 35, the surface of which is slidably connected to the inside of the transmission connecting rod 19. The square rod 35 has a square cross-section. A rotating column 33 is fixedly connected to the bottom of the square rod 35. The surface of the rotating column 33 is sealed to the inside of the top cover 16. The rotating column 33 can rotate and move up and down inside the top cover 16. An extension connecting rod 34 is fixedly connected to the bottom of the rotating column 33. The inside of the extension connecting rod 34 is a hollow structure. A pressure plate 36 is fixedly connected to the bottom of the extension connecting rod 34. By moving the pressure plate 36 downward, the pressure plate 36 can press the medicine bag and immerse the medicine bag in the water flow inside the equipment body 1, so that the water source can completely soak the medicine and make the medicine more easily decoct. A fixing ring 38 is fixedly connected to the top of the pressure plate 36. A guide groove 39 is opened on the top of the fixing ring 38. The cross-section of the guide groove 39 is T-shaped.

[0027] Please see Figure 7-8 A cylinder 22 is fixedly connected to the upper surface inside the support frame 17. The output end of the cylinder 22 is fixedly connected to a pressure rod 21 that is slidably and sealingly connected to the inside of the top cover 16. The cross-section of the pressure rod 21 is also T-shaped. The bottom end of the pressure rod 21 is slidably connected to the inside of the guide groove 39. The pressure rod 21 can move inside the guide groove 39. The cylinder 22 drives the pressure rod 21 to move up and down, which in turn drives the pressure plate 36 to move up and down through the guide groove 39 and the fixing ring 38. At the same time, the pressure plate 36 drives the rotating column 33 and the square rod 35 to move downward. During the downward movement of the pressure plate 36, it can squeeze the medicine bag inside the filter cartridge 15, so that the medicine in the medicine bag can be drained more smoothly, thereby improving the utilization rate of the medicine and reducing the waste of medicine due to storage in the medicine bag.

[0028] Please see Figure 7-10 The pressure plate 36 has multiple rotating holes 37 arranged in a circular array on its interior. Each pressure plate 36 has the same internal structure. A rotating rod 40 is rotatably connected inside each rotating hole 37. A first gripping plate 41 is fixedly connected to the bottom of the rotating rod 40. A second gripping plate 42 extending outside the first gripping plate 41 is slidably connected inside the first gripping plate 41. A barb is provided on one side of the second gripping plate 42 to catch the medicine packet and prevent it from falling off, allowing the second gripping plate 42 to grip the medicine packet more easily. When the first gripping plate 41 and the second gripping plate 42 are in a vertical position, they act as stirring rods to stir the medicine liquid. A second spring 43 is fixedly connected to the top of the second gripping plate 42, and the top of the second spring 43 is connected to the inner surface of the first gripping plate 41. The wall is fixedly connected, and the movement of the second gripper 42 can compress and reset the second spring 43. The top end of the rotating rod 40 is rotatably connected to the hinged connecting rod 44, and the outer surface of the extension connecting rod 34 is slidably connected to the movable circular plate 45. The side of the hinged connecting rod 44 away from the rotating rod 40 is rotatably connected to the surface of the movable circular plate 45. The bottom of the movable circular plate 45 is fixedly connected to the fifth spring 58 for resetting the movable circular plate 45. The fifth spring 58 is sleeved on the extension connecting rod 34, and the bottom end of the fifth spring 58 is fixedly connected to the top of the pressure plate 36. The movement of the movable circular plate 45 can compress and reset the fifth spring 58. The movable circular plate 45 drives the hinged connecting rod 44 to move downward, which can push the rotating rod 40 to rotate inside the rotating hole 37, and enable the multiple second grippers 42 to grasp the medicine pack.

[0029] Please see Figure 10 The extension connecting rod 34 has a sliding connection to a displacement transmission plate 47 extending to the outside of the extension connecting rod 34. The extension connecting rod 34 has a rotatable connection to a first gear 48 and a sliding connection to a transmission gear plate 49. The displacement transmission plate 47 and the transmission gear plate 49 are located on both sides of the first gear 48. The side of the displacement transmission plate 47 and the transmission gear plate 49 closest to the first gear 48 is provided with teeth. The displacement transmission plate 47 and the transmission gear plate 49 are meshed with the surface of the first gear 48 through the teeth. By rotating the first gear 48, the displacement transmission plate 47 and the transmission gear plate 49 can move relative to each other. The surface of the extension connecting rod 34 has a transmission displacement groove 51 that communicates with the inside of the extension connecting rod 34. The transmission displacement groove 51 has a sliding connection to a transmission pressure rod 50 that is fixedly connected to the surface of the transmission gear plate 49. The outer surface of the extension connecting rod 34 has a sliding sleeve of a transmission circular plate 46, which is located between the transmission pressure rod 50 and the movable circular plate 45.

[0030] The transmission rod 50 drives the transmission plate 46 to move downward, which in turn drives the moving plate 45 to move downward and compresses the fifth spring 58. When the transmission rod 50 moves upward, the fifth spring 58 resets and drives the moving plate 45 and the transmission plate 46 to move upward.

[0031] Please see Figure 10 The pressure plate 36 has a limiting transmission groove 54 extending to the outside of the pressure plate 36. An L-shaped fixing frame 53 is slidably connected inside the limiting transmission groove 54. A trapezoidal fixing groove 52 is provided on the side of the displacement transmission plate 47 near the L-shaped fixing frame 53. The cross-section of the trapezoidal fixing groove 52 is a right trapezoid, so that the lower surface inside the trapezoidal fixing groove 52 is inclined. The side of the L-shaped fixing frame 53 near the trapezoidal fixing groove 52 is inserted into the inside of the trapezoidal fixing groove 52. A third spring 55 is fixedly connected to one side of the L-shaped fixing frame 53. The end of the third spring 55 away from the L-shaped fixing frame 53 is fixedly connected to the inner wall of the limiting transmission groove 54. The movement of the L-shaped fixing frame 53 can compress and reset the third spring 55.

[0032] By sliding the L-shaped fixing bracket 53 into and out of the trapezoidal fixing groove 52, the position of the displacement transmission plate 47 can be fixed and released. At the same time, because the lower surface of the trapezoidal fixing groove 52 is inclined, as the displacement transmission plate 47 moves upward, the L-shaped fixing bracket 53 can slide out of the trapezoidal fixing groove 52 and slide into the next adjacent trapezoidal fixing groove 52 under the action of the third spring 55. This allows for the adjustment and fixing of the position and height of the displacement transmission plate 47 and the transmission circular plate 46. The transmission circular plate 46 can push the moving circular plate 45 to different position heights, causing the moving circular plate 45 to drive the hinged connecting rod 44 to move downwards. This causes the rotating rod 40 to drive the first gripping plate 41 and the second gripping plate 42 to rotate to different angles, allowing the first gripping plate 41 and the second gripping plate 42 to grasp medicine packets of different sizes, making it more convenient for staff to use the device.

[0033] Working principle: Step 1: Place the soaked herbs into the filter cylinder 15 (refer to...) Figure 2 The external water source is injected into the interior of the equipment body 1 through an external pipe. The operator starts the first motor 5 through the control panel. The first motor 5 drives the lifting frame 6 to move downward, and the lifting frame 6 drives the top cover 16 to move downward through the support fixing frame 17. When the filter cartridge 15 contacts the top cover 16, the first motor 5 stops rotating, the third motor 20 starts, and the second gear 72 rotates. The second gear 72 drives the second connecting support plate 68 to move through the power transmission plate 71, and the connecting fixing rod 65 slides into the interior of the connecting stabilizing hole 64, so that the filter cartridge 15 and the top cover 16 are spliced ​​and fixed. The operator starts the second motor 14 via the control panel. The second motor 14 drives the first bidirectional threaded rod 7 and the second bidirectional threaded rod 9 to rotate, causing the first clamping plate 10 and the second clamping plate 11 to slowly separate. The first motor 5 continues to rotate and drives the filter cartridge 15 to slide into the interior of the equipment body 1. The top cover 16 seals the equipment body 1. The operator starts the equipment body 1 via the control panel and enables the equipment body 1 to decoct the medicinal materials in the medicine bag. At the same time, the pressure plate 36 presses and limits the medicine bag and immerses the medicine bag in the water flow inside the equipment body 1, so that the water source can completely soak the medicinal materials and make the medicinal materials decoct more smoothly. Then start the device body 1 through the control panel and heat the water to boiling (100℃), and simmer for 45-60 minutes. Step 2: When it is necessary to stir the medicinal materials, the staff starts the third motor 18 through the control panel. The transmission connecting rod 19 drives the rotating column 33, the extension connecting rod 34 and the pressure plate 36 to rotate through the square rod 35, and the first grab plate 41 and the second grab plate 42 can disturb the medicine bag. At this time, the medicine bag is still completely in the water source under the restriction of the pressure plate 36 and the extended displacement transmission plate 47. At the same time, the medicine liquid is stirred so that the medicinal materials can be fully decocted. After stirring for a period of time, the third motor 18 stops rotating. Step 3: After the decoction is finished, the first motor 5 rotates in the reverse direction, causing the lifting frame 6 to move upward through the support frame 17, and slide out of the equipment body 1. At the same time, as the filter cylinder 15 moves upward, the decoction is drained from the inside of the filter cylinder 15. When it moves to the first clamping plate 10 and the second clamping plate 11, the first motor 5 stops rotating. The operator starts the second motor 14, which drives the first bidirectional threaded rod 7 and the second bidirectional threaded rod 9 to rotate. The first clamping plate 10 and the second clamping plate 11 can move relative to each other and position and clamp the filter cylinder 15 through the arc groove, so that the filter cylinder 15 can drain the decoction from the inside of the filter cylinder 15 more smoothly, thereby improving the utilization rate of the decoction. The second motor 20 starts and drives the second gear 72 to rotate, thereby causing the second gear 72 to drive the second connecting support plate 68 to move through the power transmission plate 71, and causing the connecting fixing rod 65 to slide out of the connecting stabilizing hole 64, so that the filter cartridge 15 and the top cover 16 are separated. Step 4: After the filter cartridge 15 and the top cover 16 are separated, the control panel controls the first motor 5 to continue rotating, so that the top cover 16 moves upward to a certain position. Then, the cylinder 22 drives the pressure rod 21 to move downward, and the pressure rod 21 drives the pressure plate 36 to move downward, so that the displacement transmission plate 47 first squeezes the medicine bag. At the same time, after the displacement transmission plate 47 moves upward to the limit position, it cooperates with the pressure plate 36 to press the medicine bag, so that the medicine liquid is drained out, thereby improving the utilization rate of the medicine liquid to a certain extent. Step 5: Simultaneously, during the pressing of the medicine bag by the pressure plate 36, the displacement transmission plate 47 first contacts the medicine bag. Because the medicine bag has a certain height and is not compressed too thin, as the pressure plate 36 descends, the medicine bag pushes the displacement transmission plate 47 upwards, causing the displacement transmission plate 47 to drive the first gear 48 to rotate. The rotation of the first gear 48 causes the displacement transmission plate 47 and the transmission gear plate 49 to move relative to each other, and the transmission gear plate 49 drives the transmission pressure rod 50 downwards. The transmission pressure rod 50 then drives the transmission circular plate 46 downwards, enabling the transmission circular plate 46 to drive the moving circular plate 45 to move downwards. The device moves downwards and compresses the fifth spring 58. Simultaneously, the lower surface of the trapezoidal fixing groove 52 is inclined. During the upward movement of the displacement transmission plate 47, the L-shaped fixing frame 53 can slide out of the trapezoidal fixing groove 52. This allows the transmission circular plate 46 to push the moving circular plate 45 to different heights, causing the moving circular plate 45 to drive the hinged connecting rod 44 to move downwards. This causes the rotating rod 40 to drive the first gripping plate 41 and the second gripping plate 42 to rotate to different angles, enabling the first gripping plate 41 and the second gripping plate 42 to grasp medicine packets of different sizes when closed, making it more convenient for staff to use the device. Step 6: After the medicine bag is grabbed, the operator starts the cylinder 22 through the control panel. The cylinder 22 drives the pressure rod 21 to move upward, which in turn drives the pressure plate 36 to move upward through the guide groove 39 and the fixing ring 38, thus grabbing the medicine bag out of the filter cylinder 15, making it easier to retrieve. After the device grabs the medicine bag and moves it upward out of the filter cylinder 15, the operator manually pulls the L-shaped fixing bracket 53 to slide out of the trapezoidal fixing groove 52, releasing the position of the transmission circular plate 46. This resets the fifth spring 58, which in turn drives the moving circular plate 45 and the transmission circular plate 46 to reset upward. This causes the moving circular plate 45 to drive the hinged connecting rod 44 to move upward, causing the rotating rod 40 to drive the first gripping plate 41 and the second gripping plate 42 to rotate, releasing the gripping of the medicine bag by the multiple second gripping plates 42. At this time, the operator can retrieve the medicine bag that has been grabbed into the air, making the retrieval of the medicine bag smoother, reducing the labor intensity of the operator to a certain extent, and making it easier for the operator to use the device.

[0034] Based on the above technical solution, the present invention provides another new technical solution: a formula for a blood-activating, collaterals-clearing, lung-benefiting, and stasis-removing decoction, comprising 30g of Astragalus membranaceus, 20g of Salvia miltiorrhiza, 10g of Ginseng, and 15g of Ligusticum chuanxiong.

[0035] Among them: Benefiting the lungs: Highlighting the role of astragalus and ginseng in replenishing lung qi, targeting the core pathogenesis of "lung qi deficiency" in ALI, and improving oxygenation by enhancing the lung qi dispersing and descending function.

[0036] Unblocking blood stasis: This reflects the effects of Danshen and Chuanxiong in promoting blood circulation and removing blood stasis, improving microcirculation disorders in ALI, reducing alveolar-capillary exudation, and reducing lung tissue damage.

[0037] Furthermore, tonifying Qi and strengthening the body's foundation: Astragalus and ginseng: High doses of Qi-tonifying herbs can regulate immune cells (such as macrophage polarization), inhibit excessive activation of inflammatory signaling pathways such as NF-κB and TLR4, and reduce the release of pro-inflammatory factors such as TNF-α and IL-6. (See reference for further information.) Figure 13 .

[0038] Ginseng: Contains ginsenosides, which can reduce oxidative stress, protect alveolar epithelial cell tight junction proteins (such as ZO-1), and reduce pulmonary edema.

[0039] Furthermore, promoting blood circulation and clearing the meridians: Danshen and Chuanxiong: Tanshinone and ligustrazine can inhibit the activation of NLRP3 inflammasomes and reduce cell pyroptosis; at the same time, they can improve pulmonary microcirculation, reduce the pulmonary vascular permeability index (LPI), and alleviate inflammatory cell infiltration in the alveoli.

[0040] Specifically, Astragalus membranaceus (Huang Qi) is slightly warm in nature and has a sweet and slightly bitter taste. It contains polysaccharides, saponins, flavonoids, and other components, and belongs to the category of Qi-tonifying herbs. Its main functions include tonifying Qi and strengthening the exterior, promoting diuresis and detoxification, draining pus, astringing sores and promoting tissue regeneration, and raising Yang and lifting prolapsed tissues. It enters the spleen and lung meridians and is mainly used to treat symptoms such as Qi deficiency and fatigue, poor appetite and loose stools, Qi sinking, chronic diarrhea and rectal prolapse, spontaneous sweating and night sweats. Specifically, Danshen (Salvia miltiorrhiza) is slightly cold in nature and bitter in taste. It contains tanshinone, tanshinone and other components, and belongs to the category of drugs that promote blood circulation and remove blood stasis. Its main effects include promoting blood circulation and removing blood stasis, regulating menstruation and relieving pain, clearing the heart and relieving irritability, cooling blood and eliminating carbuncles, and improving microcirculation. It enters the heart and liver meridians and is mainly used to treat menstrual disorders, amenorrhea and dysmenorrhea, chest and abdominal pain, abdominal masses, and insomnia. Specifically, ginseng is slightly warm in nature and has a sweet and slightly bitter taste. It contains ginsenosides, polysaccharide compounds, and other components, and belongs to the category of drugs that greatly replenish vital energy. Its main effects include greatly replenishing vital energy, restoring pulse and consolidating the body, tonifying the spleen and lungs, promoting body fluid production and calming the mind, and improving intelligence and strengthening the heart. It enters the spleen, lung, and heart meridians and is mainly used to treat symptoms such as physical weakness and impending collapse, cold limbs and weak pulse, spleen deficiency and poor appetite, lung deficiency and cough, palpitations and insomnia. Specifically, Chuanxiong (Ligusticum striatum) is warm in nature and pungent in taste. It contains ligustrazine, volatile oil and other components. It belongs to the category of drugs that promote blood circulation and regulate qi. Its main functions include promoting blood circulation and regulating qi, dispelling wind and relieving pain, and unblocking qi and blood. It enters the liver, gallbladder and pericardium meridians and is mainly used to treat menstrual disorders, headaches, rheumatic pain, traumatic injuries, chest and rib pain and other symptoms.

[0041] Based on the above-mentioned technical solutions, this invention provides another new technical solution: a preparation process for a blood-activating, meridian-clearing, lung-benefiting, and stasis-removing decoction, comprising the following specific operational steps: S1. Pre-treatment of medicinal materials: Astragalus membranaceus: remove impurities, wash, and cut into thick slices; Salvia miltiorrhiza: remove impurities, wash, and cut into thick slices; Ginseng: remove impurities, wash, and cut into thin slices; Ligusticum chuanxiong: remove impurities, wash, and cut into thick slices; S2. Soaking: Mix the four medicinal herbs, add 8-12 times the total weight of the herbs in purified water, and soak at room temperature for 30-60 minutes to allow the herbs to fully absorb water and swell. S3, Decoction and Extraction: After soaking, the medicinal materials are put into the filter cylinder 15, and external water is injected into the equipment body 1 through the external pipe. The staff then controls the system through the control panel. S4. The operator starts the equipment body 1 through the control panel, heats the water to boiling point 100℃, maintains a gentle boil for 45-60 minutes, and presses the medicine bag with the pressure plate 36 to immerse the medicine bag in the water inside the equipment body 1, so that the water source can completely soak the medicine and the medicine can be decocted more smoothly. S5. After the medicinal materials have been decocted, the staff removes the filter cylinder 15 through the control panel and squeezes out the remaining liquid in the medicine bag through the pressure plate 36 to obtain the blood-activating, meridian-clearing, lung-benefiting, and stasis-removing decoction.

[0042] By emphasizing both "tonifying qi" and "activating blood circulation," high doses of qi-tonifying herbs such as astragalus and ginseng are used to regulate immune cell polarization and inhibit excessive activation of inflammatory signaling pathways. Meanwhile, danshen and chuanxiong are used to activate blood circulation, remove blood stasis, inhibit the activation of inflammasomes, and improve microcirculation, thus forming a synergistic treatment mechanism of "tonifying qi to help blood circulation and activating blood circulation to help unblock collaterals."

[0043] Meanwhile, we established an LPS-induced acute lung injury (ALI) mouse model. Compared with the model group, the Yifei Tongyu Decoction group showed increased oxygen partial pressure, decreased carbon dioxide partial pressure, and decreased lung wet-to-dry weight ratio (P<0.01). Figure 13 In addition, HE staining of lung tissue showed that after LPS-induced ALI, the model group exhibited more severe alveolar edema, alveolar septal thickening, and leukocyte infiltration, while the treatment with Yifei Tongyu Decoction significantly reduced the degree of lung injury (P<0.01). Figure 13Further analysis using BALF ELISA revealed that Yifei Tongyu Decoction reduced the levels of IL-1β, TNF-α, and IL-6 (P<0.01).

[0044] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
