Description

Technical Field

[0001] This invention relates to the field of medical assistive device technology, specifically to a hospital pharmaceutical dispensing device. Background Technology

[0002] When developing pharmaceuticals, staff need to mix several different agents in varying proportions and repeatedly test their effects before finalizing the drug. During preparation, staff must carefully measure the proportions of different mixed agents. Because some liquid agents may contain crystalline precipitates, repeated stirring is necessary, but incomplete dissolution or residue buildup can still occur, leading to poor experimental results. Furthermore, the need to stir several different agents results in a slow and inefficient preparation process. Prolonged standing of some mixed agents can cause oxidation, affecting the drug's efficacy and resulting in poor preparation quality. When preparing multiple doses, the same process must be repeated multiple times, making the operation cumbersome. In addition, to reduce the size of the apparatus, the preparation device is designed to be too compact, making it difficult to remove the preparation container. Summary of the Invention

[0003] To address the aforementioned problems, this invention aims to provide a hospital pharmaceutical dispensing device that can improve dispensing efficiency and reduce drug settling time; it features a stirring structure to accelerate the outflow of crystalline precipitates in liquid medications; and it includes a structure that facilitates the removal of the metering container.

[0004] The main idea of ​​the technical solution adopted in this invention is as follows: Three metering tanks and corresponding inlet pipes are designed. Spring-loaded components and conical tips are respectively installed on the inlet pipes and metering tanks. The combination of these components allows for controllable drug outflow time, preventing excessively long drug settling time. A sealing plate for a leakage hole is installed on the side wall of the metering tank. The flow rate is controlled by a flow meter. Once the expected flow rate is reached, the sealing plate slides downwards to block the leakage hole, stopping the drug outflow and thus controlling the amount of drug in the dispensing tank. An auxiliary gear is installed on the inlet pipe. Driven by a driving gear, the auxiliary gear rotates, which in turn rotates the inlet pipe. This rotation causes the outflowing drug to be affected by centrifugal force, allowing it to flow out quickly when passing through the positioning plate, and also facilitating the outflow of crystalline precipitates in the liquid drug. A rotatable placement base is designed. A support block is installed on the outside of the placement base. The support block and the placement base are rotatably connected by an adjusting rod. The adjusting rod rotates eccentrically to adjust the distance between the support block and the placement base, allowing the support block to lift the dispensing tank.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A hospital pharmaceutical dispensing device includes a chassis and multiple measuring barrels, each measuring barrel having a leakage hole and a sealing structure for controlling the opening and closing of the leakage hole. The chassis (1) is also provided with a medicine dispensing tank (7), and the bottom of the medicine dispensing tank (7) is provided with an eccentric rotating structure that can lift the medicine dispensing tank (7).

[0006] Furthermore, the above technical solution includes: an attraction plate disposed on the inner wall of the metering barrel, the inner wall of the metering barrel being slidably connected to the attraction plate, the attraction plate and the attraction plate being connected by a guide rod, and a second spring being sleeved on the guide rod, with the second spring located between the attraction plate and the attraction plate.

[0007] Furthermore, the above technical solution includes: an electromagnet capable of changing magnetism is provided inside the attraction plate, and a magnetic component is provided inside the sealing plate.

[0008] Furthermore, the above technical solution includes: a placement seat for placing a medicine dispensing container, an adjusting rod rotatably connected to the placement seat, a support block rotatably connected to the other end of the adjusting rod, and the support block sliding in the radial direction of the placement seat.

[0009] Furthermore, based on the above technical solution, the placement seat includes a support plate and a tray connected by a central shaft, a connecting shaft is provided between the support plate and the tray along the circumferential direction, and the adjusting rod is sleeved on the connecting shaft.

[0010] Furthermore, the above technical solution also includes a lifting frame, which is mounted on the chassis and includes a drug inlet pipe corresponding to the metering barrel. A spring lifting assembly is provided at the bottom of the drug inlet pipe, and the spring lifting assembly controls the opening and closing of the drug inlet pipe.

[0011] Furthermore, the above technical solution includes: a rotating seat at the bottom of the drug inlet tube, a flow groove inside the rotating seat, and a spring lifting assembly inside the flow groove.

[0012] Furthermore, based on the above technical solution: the spring lifting assembly includes a movable seat and a spring, the movable seat includes an integrally connected movable plug and a movable rod, and the spring is sleeved on the movable rod.

[0013] Furthermore, the metering barrel is equipped with a positioning plate inside, and the positioning plate has a pointed tip.

[0014] Furthermore, the above technical solution includes a gear rotation structure that drives the drug inlet tube to rotate.

[0015] The beneficial effects of this invention are: 1. By designing three metering barrels and corresponding drug inlet pipes, spring lifting components and conical tips are respectively set on the drug inlet pipes and metering barrels. The two work together to make the drug outflow time controllable and avoid the drug standing time being too long. 2. A sealing plate for the leakage hole is installed on the side wall of the metering tank. The amount of medicine is controlled by the flow meter. After the expected flow rate is reached, the sealing plate slides down to block the leakage hole, and the medicine stops flowing out, thereby accurately controlling the amount of medicine in the mixing tank. 3. An auxiliary gear is installed on the inlet tube. The auxiliary gear is driven by the drive gear to rotate, which in turn drives the inlet tube to rotate. The rotation of the inlet tube causes the outflowing liquid medicine to be affected by centrifugal force. When it flows through the positioning plate, it can flow out quickly, which is also conducive to the outflow of crystalline precipitates in the liquid medicine. 4. The design includes a rotatable placement base with three support blocks on the outside. The support blocks are rotatably connected to the placement base via an adjusting rod. The adjusting rod rotates eccentrically to adjust the distance between the support blocks and the placement base, allowing the support blocks to lift the medicine dispensing container.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0018] The inventors discovered that when developing pharmaceuticals, workers need to mix several different agents in varying proportions and repeatedly test their effects before the drug can be formulated. During the mixing process, workers must carefully measure the proportions of several different agents. Because some liquid agents contain crystalline precipitates, repeated stirring is necessary, but insufficient dissolution can still occur, leading to poor experimental results. Furthermore, the need to stir several different agents results in a slow mixing speed and low efficiency. Additionally, prolonged standing of some mixed agents can cause oxidation, affecting the drug's efficacy and resulting in poor formulation quality.

[0019] Based on the above findings, this application proposes a hospital pharmacy dispensing device. It features three measuring containers and corresponding inlet pipes. Spring-loaded components and conical tips are respectively installed on the inlet pipes and measuring containers, allowing for controllable drug outflow time and preventing excessively long drug settling times. A sealing plate with a leakage hole is installed on the side wall of the measuring container. The flow rate is controlled by a flow meter; once the expected flow rate is reached, the sealing plate slides downwards to block the leakage hole, stopping the drug flow and thus controlling the amount of drug in the dispensing container. An auxiliary gear is installed on the inlet pipe, which rotates under the drive gear, causing the inlet pipe to rotate. This rotation causes the outflowing drug to be affected by centrifugal force, allowing it to flow out quickly when passing through the positioning plate. A rotatable base is designed, with a support block on its outer side. The support block and base are rotatably connected by an adjusting rod. The adjusting rod rotates eccentrically to adjust the distance between the support block and the base, allowing the support block to lift the dispensing container. Example 1

[0020] See Figures 1-12 This application discloses a hospital pharmaceutical dispensing device, including a chassis 1, three support seats fixedly connected below the chassis 1, three sets of telescopic rods 2 on the chassis 1, a support plate 3 above the telescopic rods 2, and a gear mounting plate 4 on the support plate 3.

[0021] The telescopic rod 2 uses an existing electric push rod, with a fixed lower end that is fixedly connected to the chassis 1, and a telescopic upper end. The length of the telescopic rod 2 can be controlled by controlling the electric push rod. A support plate 3 is fixedly connected to the telescopic end of the telescopic rod 2. The support plate 3 has a disc-shaped structure and three receiving holes 301. The receiving holes 301 are evenly distributed on the support plate 3 and have a fan-shaped annular structure.

[0022] A gear mounting plate 4 is connected to the center of the support plate 3 via a support column 402. The gear mounting plate 4 is disc-shaped and has three circular holes. Three medicine inlet tubes 5 are inserted through the circular holes and are movably connected to the gear mounting plate 4. A rotating ring 501 is fixedly connected to the medicine inlet tube 5 via a connecting rod. The rotating ring 501 is movably connected within the receiving hole 301.

[0023] The support plate 3 includes a central support plate and three limiting plates on the outer side of the support plate. A fixing ring is provided on the outer side of each limiting plate. The support plate, limiting plates, and fixing rings are integrally connected. The support plate and limiting plates have a disc structure, with the three limiting plates evenly distributed on the outer circumferential surface of the support plate. Sliding grooves 302 are formed on the outer circumferential surface of the support plate and the inner circumferential surface of the fixing rings, and the rotating ring 501 moves within the corresponding sliding grooves 302. A limiting hole 507 is formed in the center of the support plate, and an annular groove is formed on the support column 402. The support plate and the support column 402 are movably connected, allowing the support column 402 to rotate on the support plate.

[0024] A drive gear 401 is fitted onto the support column 402. The drive gear 401 is controlled to rotate by an external motor. The motor is connected to the drive gear via a coupling, and the support column 402 rotates synchronously with the drive gear 401 during rotation. An auxiliary gear 403 is fitted onto the inlet tube 5. The auxiliary gear 403 is fixedly connected to the outer wall of the inlet tube 5. All three auxiliary gears 403 mesh with the drive gear 401. When the drive gear 401 rotates, it drives the auxiliary gears 403 to rotate, thereby driving the inlet tube 5 to rotate. The inlet tube 5 is made of transparent material, allowing for easy observation of the internal liquid through its outer wall.

[0025] Three tubular mounting bases 101 are provided on the chassis 1, corresponding to the positions of the drug inlet tube 5. A metering container 6 is housed inside each mounting base 101, with its outer wall in contact with the inner wall of the mounting base 101, and is a detachable structure. A positioning plate 601 is fixedly connected inside the metering container 6. The lower surface of the positioning plate 601 is horizontal, and its upper surface is an inclined arc shape. A conical tip 602 is fixedly connected to the upper surface of the positioning plate 601.

[0026] The chassis 1 is also equipped with a dispensing tank 7 and a receiving seat 102 for placing the dispensing tank 7. The dispensing tank 7 is a detachable structure and is located inside the three measuring tanks 6. The dispensing tank 7 has a concave surface to facilitate liquid flow. Each measuring tank 6 has a leakage hole 603, and a connecting pipe 8 is provided at the leakage hole 603. The other end of the connecting pipe 8 extends into the dispensing tank 7. The measuring tank 6 is made of transparent material and has graduation lines on its outer wall. Example 2

[0027] refer to Figures 1-12 The bottom of the inlet tube 5 is integrally connected to a rotating seat 502, which is designed as a funnel-shaped structure, smaller at the top and larger at the bottom. The inlet tube 5 has a cylindrical inlet channel 503 inside, and the rotating seat 502 has a flow groove 504 inside. The diameter of the flow groove 504 is smaller than the diameter of the inlet channel 503. The bottom of the rotating seat 502 has multiple flow holes 505. The liquid medicine flows from the inlet channel 503 through the flow groove 504 and finally flows out through the flow holes 505.

[0028] The flow channel 504 is internally equipped with a spring-lifting assembly 506, including a movable seat 5061 and a spring 5062. The movable seat 5061 includes an integrally connected movable plug and a movable rod. The movable plug has a disc-shaped structure with the same diameter as the flow channel 504, and the movable rod has a cylindrical structure. The spring 5062 is sleeved on the movable rod. One end of the spring 5062 is fixedly connected to the upper surface of the bottom of the rotating seat 502, and the other end is fixedly connected to the lower surface of the movable plug. The lower end of the movable rod extends outward through a limiting hole 507 opened at the bottom of the rotating seat 502.

[0029] In the initial state, the movable seat 5061 is located inside the flow channel 504, blocking the flow channel 504 and preventing the liquid medicine from flowing out through it. At this time, the spring 5062 is in a compressed state. When the tip 602 on the surface of the positioning plate 601 presses upward against the movable rod, the movable seat 5061 moves upward as a whole, and the movable plug enters the medicine inlet channel 503. At this time, the flow channel 504 is in a free state, and the liquid medicine flows from the medicine inlet channel 503 through the flow channel 504 and finally flows out through the flow hole 505. When the tip 602 no longer presses against the movable rod, the spring 5062 drives the movable seat 5061 to return to the initial state, and the flow channel 504 returns to the blocked state. Example 3

[0030] refer to Figures 1-12 To avoid drug residue during the dispensing process, a waterproof coating is applied to the surface of the parts through which the drug flows, ensuring that the liquid flows without leaving any residue and preventing waste of the drug.

[0031] A longitudinal movable groove 604 is formed on the side wall of the metering tank 6, and the movable groove 604 is set on the same axis as the leakage hole 603. A sealing plate 605 is installed in the movable groove 604 and slides within it. A guide rod 606 is fixedly connected above the sealing plate 605. An attraction plate 607 is installed above the movable groove 604, and the guide rod 606 passes through the attraction plate 607 and extends outward. An electromagnet is installed in the attraction plate 607, and its magnetism can be changed by controlling the energization state of the electromagnet. A magnetic component with fixed magnetic poles is installed in the sealing plate 605. When the magnetic poles of the electromagnet and the magnetic component are the same, they repel each other, and the sealing plate 605 moves downward; when their magnetic poles are different, they attract each other, and the sealing plate 605 moves upward.

[0032] A second spring 608 is fitted onto the guide rod 606. One end of the second spring 608 is fixedly connected to the lower surface of the suction plate 607, and the other end is fixedly connected to the upper surface of the sealing plate 605. A flow meter 9 is installed on the connecting pipe 8, and a controller 10 is installed on the metering tank 6. The controller 10 controls the activation and deactivation of the flow meter 9 and the energization state of the electromagnet, thereby precisely regulating the dosage of the medicine.

[0033] In the initial state, the electromagnet and the magnetic component have different magnetic poles and attract each other. The sealing plate 605 moves upward and the leakage hole 603 is unobstructed. When the flow meter 9 indicates that the expected flow rate has been reached, the controller 10 controls the electromagnet to change its magnetism. The magnetic poles become the same and repel each other. The sealing plate 605 moves downward to block the leakage hole 603, and the liquid stops flowing out, thereby controlling the amount of medicine in the medicine tank 7. Example 4

[0034] refer to Figures 13-19 Below the medicine dispensing tank 7, there is a placement seat 103 that is rotatably connected to the chassis 1. The placement seat 103 includes a support plate 1031, a tray 1032 and a central shaft 1033 that are integrally connected. There is a certain distance between the support plate 1031 and the tray 1032. The central shaft 1033 passes through the support plate 1031 located below and extends downward through a round hole opened in the chassis 1. A second motor is provided at the end of the central shaft 1033 to drive the placement seat 103 to rotate. The second motor is located below the chassis 1.

[0035] Three connecting shafts are evenly arranged circumferentially between the support plate 1031 and the tray 1032. Adjusting rods 104 are sleeved on the connecting shafts and are rotatably connected to them. A support block 105 is rotatably connected to the other end of the adjusting rod 104. The support block 105 has a triangular structure, with the end closer to the placement seat 103 being lower and the end farther from the placement seat 103 being higher. Three guide grooves 106 are evenly formed on the outer side of the placement seat 103. The support block 105 slides within the guide grooves 106. A spring 107 is connected to the side of the support block 105 near the end of the guide groove 106. One end of the spring 107 is fixedly connected to the support block 105, and the other end is fixedly connected to the rear wall of the end of the guide groove 106.

[0036] When the medicine container 7 needs to be removed, control motor 2 rotates counterclockwise by a certain angle, causing the placement seat 103 to rotate in the same direction. The placement seat 103 then drives the adjusting rod 104 to rotate, increasing the tilt angle and causing the support block 105 to slide closer to the placement seat 103. The medicine container 7 is then lifted by the support block 105. After the medicine container 7 is removed, control motor 2 rotates clockwise by the same angle, causing the placement seat 103 to rotate clockwise. The placement seat 103 then drives the adjusting rod 104 to rotate, decreasing the tilt angle and causing the support block 105 to slide away from the placement seat 103, returning to the initial state.

[0037] The usage process of this invention is as follows: 1. Inject various liquid medicines into the inlet pipe 5, install the dispensing tank 7 and the metering tank 6, and extend the connecting pipe 8 into the dispensing tank 7. Start the controller 10, turn on the flow meter 9, and energize the electromagnet. At this time, the electromagnet and the magnetic component have different magnetic poles, and the two attract each other. The sealing plate 605 moves upward, and the leakage hole 603 is unobstructed.

[0038] 2. Connect the motor and start it together, which will drive the drive gear 401 to rotate, which in turn drives the auxiliary gear 403 to rotate, which in turn drives the medicine inlet tube 5 to rotate.

[0039] 3. Adjust the length of the telescopic rod 2 so that the telescopic rod 2 is lowered. Then, when the tip 602 of the positioning plate 601 presses against the movable rod upward, the movable seat 5061 moves upward as a whole, and the movable plug enters the inside of the drug inlet channel 503. At this time, the flow channel 504 is in a smooth state, and the medicine flows from the drug inlet channel 503 through the flow channel 504 and finally flows out through the flow hole 505.

[0040] 4. When the flow meter 9 indicates that the expected flow rate has been reached, the controller 10 controls the electromagnet to change its magnetism. When the magnetic poles are the same, they repel each other. The sealing plate 605 moves down to block the leakage hole 603, and the liquid stops flowing out, thereby controlling the amount of medicine in the medicine tank 7.

[0041] 5. After the medication is prepared, turn off motor one and controller 10. Remove the measuring container 6 for cleaning and disinfection. Clean the inlet tube 5 using a misting cleaning machine. Control motor two to rotate counterclockwise by a certain angle, causing the placement seat 103 to rotate in the same direction. The placement seat 103 drives the adjusting rod 104 to rotate, increasing the tilt angle and causing the support block 105 to slide closer to the placement seat 103. The medication container 7 is then lifted by the support block 105. After the medication container 7 is removed, control motor two to rotate clockwise by the same angle, causing the placement seat 103 to rotate clockwise. The placement seat 103 drives the adjusting rod 104 to rotate, decreasing the tilt angle and causing the support block 105 to slide away from the placement seat 103, returning to the initial state.

[0042] Application Cases

[0043] This device can be used to prepare chloral hydrate solution. For example, to prepare 250ml of 10% chloral hydrate solution, first weigh 25g of chloral hydrate using a pharmaceutical balance and put it into one of the inlet tubes 5. Add an appropriate amount of water to dissolve it. Start motor 1 to rotate the inlet tube 5 to accelerate dissolution. After rotating for a period of time and observing that the chloral hydrate is completely dissolved, adjust the length of the telescopic rod 2 to lower it. Then, the tip 602 on the surface of the positioning plate 601 presses upward against the movable rod, allowing the liquid to flow into the preparation tank 7. Observe the scale line of the preparation tank and add water to 250ml through the inlet tube 5.
