Description

Technical Field

[0001] This invention relates to the field of intravenous drug preparation technology, and in particular to a drug dispensing mechanism for a drug storage tank, a drug storage tank, and an automated drug dispensing device. Background Technology

[0002] Against the backdrop of the increasingly refined development of the healthcare system, the intravenous medication preparation center, as the core hub of hospital pharmacy management, directly impacts clinical medication safety through its operational efficiency and quality control. However, the traditional manual medication preparation model has long faced multiple challenges: First, the high intensity of manual operation, requiring pharmacists to repeatedly sort medications (over a thousand times daily), leads to occupational fatigue and increases the risk of operational errors; second, the high error rate of manual medication preparation results in serious safety hazards such as incorrect solvent specifications and mixed medications; and third, insufficient process standardization, with individual differences in manual operation making it difficult to achieve full-process traceability and quality control, failing to meet the stringent requirements of modern medicine for precision medication.

[0003] Therefore, providing an automated drug dispensing device is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] This invention discloses a drug dispensing mechanism for a drug storage tank, a drug storage tank, and an automated drug dispensing device, in order to solve the aforementioned technical problems existing in related technologies.

[0005] To solve the above problems, the present invention adopts the following technical solution: In a first aspect, this application provides a drug dispensing mechanism for a drug storage tank, the drug dispensing mechanism comprising: A tray for holding medicine bottles; A shielding assembly is rotatably disposed relative to the tray. The shielding assembly has a first state and a second state. In the first state, the shielding assembly shields the first medicine bottle. In the second state, the shielding assembly avoids the first medicine bottle and shields the second medicine bottle. A trigger, which is connected to the blocking assembly, is configured to drive the blocking assembly to rotate under the action of an external force, so that the blocking assembly switches from a first state to a second state; An elastic reset mechanism is connected to the blocking component to drive the blocking component to switch from a second state to a first state.

[0006] Furthermore, the shielding assembly includes a base plate, a first swing arm, a second swing arm, a first shielding member, and a second shielding member, wherein the base plate is movably disposed relative to the tray, and both ends of the base plate extend to the upper and lower sides of the tray respectively; the first swing arm and the second swing arm are respectively connected to the base plate, and the first swing arm is located above the tray, and the second swing arm is located below the tray. The rotation axis of the shielding assembly is located at the lower part of the shielding assembly. The first shielding member is connected to the first swing arm, and the second shielding member is connected to the second swing arm. In the first state, the first shielding member is located outside the first medicine bottle to shield the first medicine bottle. In the second state, the first shielding member is raised to avoid the first medicine bottle, and the second shielding member is inserted between the first medicine bottle and the second medicine bottle. The trigger member is connected to the base plate. The movement of the trigger member can drive the shielding assembly to rotate around its rotation axis, so that the shielding assembly switches between the first state and the second state.

[0007] Furthermore, the tray is provided with slots that penetrate the tray, and a plurality of the slots are distributed along the width direction of the tray. A portion of the second shield can pass through the slots and extend between the first medicine bottle and the second medicine bottle.

[0008] Furthermore, the trigger has a pin, and the base plate is provided with a guide groove, the pin being slidably engaged in the guide groove.

[0009] Furthermore, the elastic reset mechanism includes a spring seat, a spring, and a top pin. The spring is disposed within the spring seat, the top pin abuts against the spring and the base plate, and a portion of the top pin is located within the spring.

[0010] Furthermore, the substrate has a flange on the side facing the top pin, the outer peripheral surface of the flange is an arc-shaped surface, and the top pin abuts against the outer peripheral surface of the flange.

[0011] Secondly, this application also provides a medicine storage tank, including a tank body and the aforementioned medicine storage tank dispensing mechanism. The bottom wall of the tank body is used to support a plurality of medicine bottles arranged in a row. The tank body has a discharge end, and the medicine storage tank dispensing mechanism is disposed at the discharge end.

[0012] Furthermore, the medicine storage tank also includes an upper baffle, which is fixedly disposed relative to the tank body and extends along the extending direction of the tank body. The medicine bottle is located between the upper baffle and the bottom wall of the tank body.

[0013] Furthermore, the tank is inclined relative to the horizontal plane.

[0014] Furthermore, the medicine storage tank also includes a counterweight, which is detachably disposed within the tank and can slide along the tank under the action of gravity.

[0015] Thirdly, this application also provides an automated drug dispensing device, including the aforementioned drug storage tank.

[0016] The technical solution adopted in this invention can achieve the following beneficial effects: The medicine dispensing mechanism, medicine storage tank, and automated medicine dispensing device of the present invention, under the elastic action of the elastic reset mechanism, have the initial state of the shielding component as a first state. At this time, the first medicine bottle on the tray and all subsequent medicine bottles are shielded by the shielding component and remain in a relatively static state. When it is necessary to dispense medicine, an external force is applied to the trigger, which moves towards the elastic reset mechanism under the external force, thereby driving the shielding component to rotate relative to the tray, thus switching from the first state to the second state. During this process, the elastic reset mechanism is compressed and stores medicine. The elastic potential energy is used because the blocking component in the second state only avoids the first medicine bottle while still blocking the second medicine bottle. At this time, only the first medicine bottle is released outward. When the external force applied to the trigger is removed, the elastic reset mechanism releases the elastic potential energy and drives the blocking component to rotate, switching it to the first state. The trigger is reset synchronously, and the blocking component loses its blocking of the second medicine bottle. The second medicine bottle moves along the tray to the original position of the first medicine bottle and is blocked and limited by the blocking component again. That is, the position of the second medicine bottle changes to that of the first medicine bottle. By linking the blocking component with the trigger and the elastic reset mechanism, the blocking component can switch between the first state and the second state. In the second state, only the first medicine bottle is released, and the second medicine bottle cannot move forward due to continuous blocking. This completely avoids the risk of multiple bottles sliding out or getting stuck, meeting the strict single-dose control requirements for drug dispensing in medical scenarios. It reduces the intensity of manual operation while ensuring the accuracy and efficiency of drug dispensing. Attached Figure Description

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0021] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0022] Please see Figures 1-5 This application discloses a drug dispensing mechanism for a drug storage tank, a drug storage tank, and an automated drug dispensing device. The disclosed drug dispensing mechanism for the drug storage tank can be located at the discharge end of the drug storage tank. The drug dispensing mechanism for the drug storage tank includes a support plate 100, a shielding component 200, a triggering component 300, and an elastic reset mechanism 400. The support plate 100 is the basic component of the drug dispensing mechanism for the drug storage tank and can provide an installation base for the shielding component 200, the triggering component 300, and the elastic reset mechanism 400. That is, the shielding component 200, the triggering component 300, and the elastic reset mechanism 400 are located on the support plate 100.

[0023] Please see Figure 1 and Figure 5The tray 100 can be part of the bottom wall of the medicine storage tank. The tray 100 is used to support medicine bottles. For example, the medicine bottles can be ampoules or vials. Multiple medicine bottles are arranged and supported on the tray 100 to form a medicine bottle array. In this embodiment, for ease of subsequent description, along the discharge direction of the medicine bottles, the first medicine bottle at the foremost point is defined as the first medicine bottle 800, and the second medicine bottle immediately behind the first medicine bottle 800 is defined as the second medicine bottle 900.

[0024] In this embodiment of the application, the shielding component 200 is rotatably disposed relative to the tray 100. For example, the shielding component 200 has a rotating shaft 260. When the medicine dispensing mechanism of the medicine storage tank is installed in the medicine storage tank, the rotating shaft 260 can rotate and cooperate with the side wall of the medicine storage tank, thereby rotating relative to the tray 100. Of course, it can also be understood that the shielding component 200 swings relative to the tray 100. The shielding component 200, which is rotatably disposed relative to the tray 100, has a first state and a second state. In the first state, the shielding component 200 shields the first medicine bottle 800. At this time, all medicine bottles arranged after the first medicine bottle 800 are sequentially blocked. When the shielding component 200 rotates relative to the tray 100 to the second state, the shielding component 200 avoids the first medicine bottle 800, allowing the first medicine bottle 800 to be output from the front end of the tray 100. For example, the tray 100 is tilted relative to the horizontal plane, and the first medicine bottle 800 can fall from the front end of the tray 100 under the action of gravity. At the same time, the shielding component 200 in the second state also shields the second medicine bottle 900 to prevent it from falling with the first medicine bottle 800, thereby preventing continuous dispensing of medicine.

[0025] In this embodiment, both the trigger 300 and the elastic reset mechanism 400 are connected to the blocking assembly 200, and are distributed on opposite sides of the blocking assembly 200. The trigger 300 can be a rod-shaped member, configured to drive the blocking assembly 200 to rotate under external force, switching the blocking assembly 200 from a first state to a second state. During this process, the elastic reset mechanism 400 stores elastic potential energy. When the external force applied to the trigger 300 is removed, the elastic reset mechanism 400 releases the elastic potential energy, driving the blocking assembly 200 to rotate again and switch from the second state back to the first state. It should be noted that the external force applied to the trigger 300 in this application refers to an external force acting on the trigger 300 and directed towards the elastic reset mechanism 400. This external force can be applied manually to the trigger 300 or by a mechanical component; this application does not impose specific limitations on this.

[0026] Based on the above technical solution, in specific applications, the dispensing mechanism of the storage tank in this embodiment, under the elastic action of the elastic reset mechanism 400, initially holds the first state of the blocking component 200. At this time, the first medicine bottle 800 and all subsequent medicine bottles on the tray 100 are blocked by the blocking component 200 and remain in a relatively static state. When dispensing medicine is required, an external force is applied to the trigger 300, which moves towards the elastic reset mechanism 400 under the external force, thereby driving the blocking component 200 to rotate relative to the tray 100, thus switching from the first state to the second state. During this process, the elastic reset mechanism 400 is compressed and stores elastic potential energy. Since the blocking component 200 in the second state only avoids the first medicine bottle 800 while still blocking the second medicine bottle 900, only the first medicine bottle 800 is released outward at this time. When the external force applied to the trigger 300 is removed, the elastic reset mechanism 400 releases elastic potential energy and drives the blocking component 200 to rotate, switching it to the first state. The trigger 300 resets synchronously, and the blocking component 200 loses its blocking of the second medicine bottle 900. The second medicine bottle 900 moves along the support plate 100 to the original position of the first medicine bottle 800 and is blocked and limited by the blocking component 200 again. That is, the position of the second medicine bottle 900 changes to that of the first medicine bottle 800.

[0027] Through the coordinated operation of the blocking component 200, the trigger 300, and the elastic reset mechanism 400, the blocking component 200 can switch between the first state and the second state. In the second state, only the first medicine bottle 800 is released, and the second medicine bottle 900 cannot move forward due to continuous blocking, thus completely avoiding the risk of multiple bottles sliding out or getting stuck. This meets the strict single-dose control requirements for drug dispensing in medical scenarios, reducing the intensity of manual operation while ensuring the accuracy and efficiency of drug dispensing.

[0028] In the embodiments of this application, please refer to Figure 1 , Figure 2 and Figure 3The shielding assembly 200 includes a base plate 210, a first swing arm 220, a second swing arm 230, a first shielding member 240, and a second shielding member 250. The base plate 210 is movably disposed relative to the tray 100, and both ends of the base plate 210 extend to the upper and lower sides of the tray 100, respectively. For example, along the direction of movement of the medicine bottle on the tray 100, the two base plates 210 can be disposed on the left and right sides of the tray 100. The base plate 210 can have a certain lifting range relative to the tray 100, and can also have a certain rotation range relative to the tray 100. The first swing arm 220 and the second shielding member 250... The swing arms 230 are connected to both ends of the base plate 210 respectively. The first swing arm 220 and the second swing arm 230 can be integrally connected to the base plate 210, or they can be connected and fixed to the base plate 210 by threaded fasteners. Alternatively, one of the first swing arm 220 and the second swing arm 230 can be integrally connected to the base plate 210, and the other can be connected and fixed to the base plate 210 by threaded fasteners. The first swing arm 220 is located above the support plate 100, and the second swing arm 230 is located below the support plate 100. The first swing arm 220, the base plate 210 and the second swing arm 230 are connected to form a U-shaped structure.

[0029] In this embodiment, the rotation axis 260 of the blocking assembly 200 is biased towards the moving direction of the trigger 300, so that the blocking assembly 200 can rotate relative to the support plate 100. For example, please refer to... Figure 1 , Figure 2 and Figure 3 The rotation shaft 260 of the shielding assembly 200 is located at the lower part of the shielding assembly 200, for example, it can be located at the junction of the second swing arm 230 or the substrate 210 and the second swing arm 230. The first shielding member 240 is connected to the first swing arm 220, and the second shielding member 250 is connected to the second swing arm 230.

[0030] In the first state, the first blocking member 240 is located outside the first medicine bottle 800 to block it. In the second state, the first blocking member 240 is raised to avoid the first medicine bottle 800, and the second blocking member 250 is raised and inserted between the first medicine bottle 800 and the second medicine bottle 900, thereby blocking the second medicine bottle 900. That is to say, the U-shaped structure, the first blocking member 240 and the second blocking member 250 form a seesaw-like structure, allowing the first blocking member 240 and the second blocking member 250 to selectively intervene in the medicine bottle's dispensing path. When the first blocking member 240 intervenes, it blocks the first medicine bottle 800, and when the second blocking member 250 intervenes, it blocks the second medicine bottle 900.

[0031] Both the trigger 300 and the elastic reset mechanism 400 are connected to the base plate 210. When the trigger 300 is moved by an external force, it can drive the U-shaped structure to rotate around its rotation axis 260, thereby switching the blocking assembly 200 from the first state to the second state. It can be understood that when the external force applied to the trigger 300 is removed, the elastic reset mechanism 400 drives the blocking assembly 200 to rotate and switch from the second state to the first state. The second medicine bottle 900 loses its constraint and moves on the tray 100 to the position of the first medicine bottle 800 and is blocked by the first blocking member 240. At this time, the second medicine bottle 900 changes into the first medicine bottle 800.

[0032] In this embodiment, the rotation shaft 260 of the shielding assembly 200 is located below the tray 100, such that the first shielding member 240 intervenes from above to shield the first medicine bottle 800, while the second shielding member 250 intervenes from below to shield the second medicine bottle 900. In other embodiments of this application, the rotation shaft 260 may also be located above the tray 100, for example, at the intersection of the base plate 210 and the first swing arm 220. When the rotation shaft 260 of the shielding assembly 200 is located above the tray 100, the first shielding member 240 can intervene from below to shield the first medicine bottle 800, and the second shielding member 250 can intervene from above to shield the second medicine bottle 900. This application does not impose specific limitations on this.

[0033] In this embodiment, the pallet 100 is provided with slots 110 penetrating the pallet 100. Multiple slots 110 are distributed along the width direction of the pallet 100, which is perpendicular to the conveying direction of the medicine bottle. A portion of the second blocking member 250 can pass through the slots 110 and extend between the first medicine bottle 800 and the second medicine bottle 900. With this configuration, the multiple slots 110 distributed along the width direction of the pallet 100 provide continuous blocking for the body of the medicine bottle, preventing tilting of the medicine bottle due to partial blocking. Furthermore, the pallet 100 has a solid portion between two adjacent slots 110. When the second blocking member 250 retracts and removes its blocking effect on the medicine bottle, the medicine bottle is always supported by this solid portion as it passes through the slot 110, thus preventing the medicine bottle from partially sinking into the slot 110 and becoming stuck, thereby ensuring smooth dispensing of the medicine bottle.

[0034] As described above, the blocking component 200 rotates when driven by the trigger 300 or the elastic reset mechanism 400. Therefore, relative sliding occurs at the connection between the trigger 300 and the blocking component 200, allowing the blocking component 200 to rotate around its rotation axis 260. Thus, in some embodiments of this application, the trigger 300 has a pin 310, and a guide groove 211 is provided on the substrate 210. Exemplarily, the guide groove 211 is formed in the middle of the substrate 210, and both ends of the guide groove 211 extend towards both ends of the substrate 210. The pin 310 is slidably engaged within the guide groove 211. That is to say, the sliding engagement between the guide groove 211 and the pin 310 essentially converts the linear motion of the trigger 300 into the rotational motion of the blocking component 200 around the rotation axis 260. Please refer to [link to relevant documentation]. Figure 3 When the trigger 300 moves to the left under the action of an external force, the blocking assembly 200 rotates counterclockwise around the rotation axis 260, and the pin 310 moves upward relative to the guide groove 211. When the external force is removed, the elastic reset mechanism 400 can drive the trigger 300 to move to the right, the blocking assembly 200 rotates clockwise around the rotation axis 260, and the pin 310 moves downward relative to the guide groove 211.

[0035] In this embodiment, the elastic reset mechanism 400 includes a spring seat 410, a spring 420, and a top pin 430. The spring seat 410 can be disposed on the support plate 100 and has a receiving space. The spring 420 is disposed in the receiving space. The top pin 430 abuts against the spring 420 and the base plate 210, and a portion of the top pin 430 is located inside the spring 420. During the process of the trigger 300 driving the blocking assembly 200 to switch from the first state to the second state, the spring 420 is compressed and stores elastic potential energy.

[0036] In a further technical solution, the substrate 210 is provided with a flange 212 on the side facing the top pin 430. The outer peripheral surface of the flange 212 is an arc-shaped surface. The top pin 430 abuts against the outer peripheral surface of the flange 212. The arc-shaped outer peripheral surface of the flange 212 and the top pin 430 form a line-to-surface contact form, which reduces the friction between the top pin 430 and the substrate 210, thereby improving the smoothness of the rotation of the shielding assembly 200.

[0037] Please see Figure 4 and Figure 5 This application also discloses a medicine storage tank, which includes a tank body 500 and the aforementioned medicine storage tank dispensing mechanism. The tank body 500 is used to store multiple medicine bottles. For example, the multiple medicine bottles can be arranged and supported on the bottom wall of the tank body 500. The tank body 500 has a discharge end, the medicine storage tank dispensing mechanism is located at the discharge end, and the tray 100 can be part of the bottom wall of the tank body 500.

[0038] In this embodiment, the medicine storage tank also includes an upper baffle 600, which is fixedly disposed relative to the tank body 500. For example, the upper baffle 600 can be connected to the bottom wall of the tank body 500 or to the side wall of the tank body 500. The upper baffle 600 extends along the extension direction of the tank body 500. The medicine bottle is located between the upper baffle 600 and the bottom wall of the tank body 500. The upper and lower sandwich structure formed by the upper baffle 600 and the bottom wall of the tank body 500 provides vertical full-stroke limit for the medicine bottle, avoiding misalignment and stacking of multiple medicine bottles. That is to say, a "single bottle channel" is formed between the upper baffle 600 and the bottom wall of the tank body 500, ensuring that only one medicine bottle passes through at a time, thereby achieving accurate dispensing.

[0039] In a further technical solution, the tank 500 is inclined relative to the horizontal plane. For example, the tank 500 is inclined at 12° to 90° relative to the horizontal plane, such as 15°. In this way, when the trigger 300 is driven to move and switch the shielding assembly 200 from the first state to the second state, the first medicine bottle 800 can fall under the action of gravity. When the elastic reset mechanism 400 drives the shielding assembly 200 to switch from the second state to the first state, the second medicine bottle 900 and the medicine bottles after it can also roll downward under the action of gravity until the second medicine bottle 900 abuts against the first shielding member 240 and transforms into the first medicine bottle 800.

[0040] In some embodiments of this application, the medicine storage tank may further include a counterweight 700, which is detachably disposed within the tank body 500. For example, when the medicine bottle is a small-volume bottle with a relatively large mass at the bottle head, it is prone to tilting or even jamming when moving on the support plate 100 under its own weight. In other words, the small-volume medicine bottle cannot move stably on the support plate 100 under its own weight. In this case, the counterweight 700 can be naturally placed above all the medicine bottles, with smooth contact between the counterweight 700 and the bottom wall of the tank body 500. The counterweight 700 can slide along the tank body 500 under gravity. When the medicine bottle experiences sluggish movement due to surface friction, bottle deformation, or tank structure errors, the gravitational potential energy of the counterweight 700 is converted into a pushing force on the medicine bottle, thereby ensuring smooth movement of the medicine bottle.

[0041] Of course, in some embodiments of this application, the medicine storage tank may be equipped with a pushing structure for feeding the medicine bottles, so that the multiple medicine bottles arranged on the tray 100 always have a tendency to be fed outwards. For example, the pushing structure may be a compression spring connected to the aforementioned counterweight 700. Under the elastic force of the compression spring, the counterweight 700 can always apply a pushing force to the multiple medicine bottles, thereby ensuring that the medicine bottles can be fed outwards smoothly. Of course, in other embodiments of this application, the pushing structure may also be in the form of a linear motor, an electric push rod, etc., and this application does not impose specific limitations on this. It is understood that when the medicine storage tank is equipped with a pushing structure, the tank body 500 can be selected from either a horizontal arrangement or an inclined arrangement.

[0042] In a further technical solution, the medicine storage tank can also be equipped with a guide rod, and the counterweight 700 slides with the guide rod to make the counterweight 700 move along a determined trajectory, thereby improving the stability of the movement of the counterweight 700; of course, in order to improve the smoothness of the movement of the counterweight 700, rollers or rolling bearings can also be provided on the counterweight 700.

[0043] In some embodiments of this application, a guide seat 1000 is also provided on the pallet 100. The trigger 300 can be slidably fitted in the guide seat 1000 through a linear bearing. The combination of the guide seat 1000 and the linear bearing forms a rigid guide track, ensuring that the trigger 300 moves linearly along a preset axis and avoiding swaying, tilting or radial movement. The linear bearing significantly reduces the movement resistance of the trigger 300 through rolling friction or optimized lubrication design, so that stable material discharge can be achieved when an external force is applied to the trigger 300.

[0044] In some embodiments of this application, the discharge end of the medicine storage tank may also be provided with an identification chip 1100. For example, the identification chip 1100 may be an RFID chip. An identification device is provided on the medicine dispensing mechanism of the medicine storage tank. The medicine dispensing operation can only be performed when the identification device successfully identifies the specific information stored or transmitted on the identification chip 1100. It is understood that the specific information may include the type information and dosage information of the medicine in the medicine.
