Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a liquid-carrying bottle insertion device, a pumping device, a drug dispensing device, and a solvent preparation method. Background Technology

[0002] In the modern medical field, many operations that were traditionally performed manually are gradually being automated. Automation in the medical field can avoid the impact of human error and reduce medical accidents; compared with manual operation, it greatly improves the speed of operation and enhances medical efficiency.

[0003] Specifically, the preparation of intravenous medications requires injecting a solvent into the vial to dissolve the drug, facilitating subsequent extraction and injection. To ensure complete dissolution, the vial is often manually shaken. To improve the dissolution rate, specialized equipment has emerged that mechanically shakes or vibrates the vial, replacing manual shaking and achieving rapid drug dissolution.

[0004] The inventors of this application discovered that in the prior art, accelerating drug dissolution by shaking or oscillating can generate air bubbles, making it impossible to immediately extract and inject the drug after shaking or oscillating. Furthermore, the inventors found that adding new drug solvents to dispensing equipment typically requires manual injection. This method not only significantly reduces dispensing efficiency but also increases labor costs. Manual operation can also lead to drug contamination and reduce the accuracy of drug injection. Therefore, this invention automates drug dispensing, reducing the possibility of contamination, ensuring complete drug dissolution, improving dispensing efficiency, and alleviating the mechanical labor of doctors in dispensing drugs.

[0009] This application also discloses a dispensing device. In one embodiment, in addition to any of the features of the liquid bottle insertion device described above, it further includes: a solvent carrier, a pressure control device, and a device carrier. The solvent carrier, the pressure control device, and the liquid bottle insertion device are fixed to the housing of the device carrier. The solvent carrier and the pressure control device are connected at their ports via conduits. The liquid bottle insertion device is connected to the other port of the pressure control device via a conduit. The device carrier contains a moving control component, a dispensing control component, and a three-way control component. The moving control component is connected to a slider of the moving part of the liquid bottle insertion device to control the up-and-down movement of the liquid bottle insertion device.

In another embodiment of the injection device application, the movement control element or injection control element is a motor or cylinder disposed inside the device carrier.

[0010] This application also discloses a dispensing device. In one embodiment of this application, in addition to any of the features of the above-described injection device, it further includes a dissolving device. The dissolving device includes at least one cup assembly, which includes at least one cup, a first support plate, and a first transmission member corresponding to each cup. The cup and the first transmission member are respectively disposed on the upper and lower surfaces of the first support plate. The first transmission member passes through the first support plate and is connected to the corresponding cup. When the first support plate does not rotate but the first transmission member rotates, the cup rotates accordingly. A second support plate is located below the cup assembly. At least one second transmission component is provided, corresponding one-to-one with the cup body assembly and passing through the second support plate. The second transmission component includes an upper transmission component and a lower transmission component. The upper transmission component is located above the second support plate and is securely connected to it. The lower transmission component is located below the second support plate and passes through the second support plate and the upper transmission component, and is securely connected to the first support plate. The upper transmission component cooperates with all the first transmission components of its corresponding cup body assembly. When the lower transmission component rotates while the upper transmission component and the second support plate do not rotate, and the first support plate rotates, causing the first transmission component to revolve, due to the transmission cooperation of the upper transmission component, the... The first transmission component also rotates; the third transmission component, located below the second support plate, includes an inner transmission component, an outer transmission component, and a fixing component. The fixing component is located between the inner and outer transmission components. Both the inner and outer transmission components can slide relative to the fixing component. The inner transmission component is connected to the second support plate. When the inner transmission component rotates, the second support plate rotates accordingly. The outer transmission component is configured to cooperate with the lower transmission component. When the outer transmission component rotates, the lower transmission component rotates accordingly. When the outer transmission component does not rotate but the lower transmission component revolves, the lower transmission component also rotates due to the transmission cooperation of the outer transmission component.

[0011] This application also discloses a solvent preparation method based on a drug preparation device, comprising the following steps: Step 1: Place the solvent bottle into the cup body; Step 2: Inject the solvent into the solvent carrier device; Step 3: Control the injection device to inject the preset standard solvent into the solvent bottle; Step 4: Control the rotation of the dissolving device, and replace the cup body of the solvent to be injected by adjusting the cup group so that it is aligned with the insertion end of the liquid carrier bottle insertion device. Repeat step 3. The steps for adjusting the cup set include: The first power device enables the cup assembly to rotate to any position on the second support plate. Once the cup assembly has rotated to the preset position, the first power device can be stopped, and the second power device will start working, driving the external transmission component to rotate, and the lower transmission component to rotate accordingly, thereby realizing the rotation of all cups. Step 5: After adding solvent to all the solvent bottles in the cups, set up the dissolving device to accelerate dissolution; The accelerated dissolution process includes the following steps: When the first power unit is working and the second power unit is not working, the first power unit can drive the inner transmission component to rotate, which in turn drives the second support plate to rotate. The second transmission component then revolves around the sun. At this time, the second power unit is not working and the outer transmission component is fixed. Due to the transmission relationship between the lower transmission component and the outer transmission component, the lower transmission component rotates while revolving around the sun, which drives the first support plate to rotate. The first transmission component also revolves around the sun. Since there is no relative rotation between the upper transmission component and the second support plate, the first transmission component will also rotate, thereby driving the cup body to rotate. The second power unit can work simultaneously with the first power unit, driving the fifth transmission component to rotate in the opposite direction to the rotation of the inner transmission component. For example, when the inner transmission component rotates counterclockwise, the fifth transmission component rotates clockwise, so that the outer transmission component can accelerate its rotation in the same direction as the inner transmission component under the action of the fifth transmission component.

(Specific details to be added...) Figure 5A , 5B As shown in 5C, Figure 5A This is a three-dimensional schematic diagram showing the cup body assembly 2100, the second transmission component 2200, and the second support plate 2300 isolated from each other.

The outer transmission member 2410 is configured to cooperate with all the lower transmission members 2220 of the second transmission member. When the outer transmission member 2410 rotates, the lower transmission members 2220 rotate accordingly. When the outer transmission member 2410 is fixed and cannot rotate, but the second support plate 2300 rotates, the lower transmission members 2220 revolve around the central axis of the second support plate 2300 while rotating due to the transmission relationship with the outer transmission member 2410.

When the fifth transmission member 2600 is fixed and cannot rotate, the external transmission member 2410 also cannot rotate. The second power device 2700 includes a second power output device 2710 and a sixth transmission member 2720. The sixth transmission member 2720 is configured to cooperate with the fifth transmission member 2600. When the sixth transmission member 2720 rotates, the fifth transmission member 2600 rotates accordingly. The second power output device 2710 drives the sixth transmission member 2720 to rotate.

[0050] In the above embodiments, the fourth transmission member 2520 and the inner transmission member 2430 are driven by a belt, the sixth transmission member 2720 and the fifth transmission member 2600 are driven by a belt, and the fifth transmission member 2600 and the outer transmission member 2410 are driven by a gear. Of course, those skilled in the art should know that the above transmission method can also be replaced by other methods that can achieve the purpose of this invention, such as gear transmission, roller transmission, etc.

[0051] Continue to refer to Figure 2 , Figure 3 and Figure 6 As shown, the end of the fixing member 2420 away from the second support plate 2300 is connected to multiple support columns 2800, which are used to support the liquid-carrying bottle insertion device 1300 on the third support plate 300. The end of the fifth transmission member 2600 near the third support plate 3000 is connected to an auxiliary fixing device 2900, which fixes the fifth transmission member 2600 on the third support plate 3000.

[0052] Combination Figure 7 As shown, Figure 7 This is a cross-sectional view of the second support plate 2300, the third transmission component 2400, and the fourth transmission component 2520 after they have been isolated. The third transmission component 2400 also includes an inner fixing component 2421, a locking component 2440, a sliding component 2450, an inner rotating ring 2460, and a second connecting portion 2470. The inner fixing component 2421 is fastened to the fixing component 2420; the locking component 2440 is used to lock the sliding component 2450 between the inner fixing component 2421 and the outer transmission component 2410; the inner rotating ring 2460 can slide relative to the inner fixing component 2421, and the outer transmission component 2410 can slide relative to the inner fixing component 2421. The inner transmission component 2430 is fastened to the second connecting portion 2470 and the inner rotating ring 2460, and the inner rotating ring is also fastened to the second support plate 2300. Therefore, when the inner transmission component 2430 rotates, the third support plate 3000 also rotates.

[0053] Those skilled in the art should know that: the "rotation" mentioned in the above embodiments is generally understood as a part rotating around its central axis; the fastening connection of this application includes both two parts that are independent but connected by riveting, screw locking, gluing, etc., and two parts that are integrally formed; the "fitting setting" mentioned in the above embodiments is a general term, that is, in order to enable two parts to achieve a transmission effect, those skilled in the art know that the two parts are reasonably designed so that the two parts can cooperate with each other to achieve a transmission effect, for example, the two parts have necessary and appropriate close contact, or the two parts are both gears, and the gears of the two parts are necessary and appropriate meshing.

[0054] The dissolving device of this application, by setting up multiple sets of multi-stage transmission structures, can both allow the cup 2110 to rotate on its own axis and revolve around an axis located outside its body, thereby achieving a better dissolving effect and avoiding foam generated by vibration and other methods; the rotation speed of the cup can also be further accelerated to achieve faster and more efficient dissolving; in addition, each cup 2110 in the cup assembly 2100 can be controlled to rotate to a preset position as needed.

[0055] For example, the solvent preparation method of the drug dispensing device includes the following steps: Step 1, placing the solvent bottle in the cup body; Step 2, injecting the solvent into the solvent carrier device 1100; Step 3, controlling the injection device to inject the preset standard solvent into the solvent bottle; Step 4, controlling the dissolving device to rotate, and changing the cup body to be injected with the solvent through the cup group adjustment step, aligning it with the insertion end of the liquid carrier bottle insertion device 1300, and repeating step 3; Step 5, after completing the addition of solvent to all the solvent bottles in the cup bodies, setting the dissolving device to accelerate dissolution.

[0056] The accelerated dissolving process includes the following steps: the first power device 2500 is working, while the second power device 2700 is not working. The first power device 2500 can drive the inner transmission component 2430 to rotate, which in turn drives the second support plate 2300 to rotate. The second transmission component 2200 then revolves around the sun. Meanwhile, the second power device 2700 is not working, and the outer transmission component 2410 remains stationary. Due to the transmission relationship between the lower transmission component 2220 and the outer transmission component 2410, the lower transmission component 2220 rotates while revolving around the sun, thus driving the first support plate 2130 to rotate. The first transmission component 2120 also revolves around the sun. Since there is no relative rotation between the upper transmission component 2210 and the second support plate 2300, the first transmission component 2120 also rotates, thereby driving the cup body 2110 to rotate.

[0057] The secondary acceleration in the accelerated dissolution process includes: when the cup body is to be rotated and accelerated, the second power device 2700 can work simultaneously with the first power device, driving the fifth transmission member 2600 to rotate in the opposite direction to the rotation of the inner transmission member. For example, when the inner transmission member 2430 rotates counterclockwise, the fifth transmission member 2600 rotates clockwise, so that the outer transmission member 2410 can be accelerated to rotate in the same direction as the inner transmission member 2430 under the action of the fifth transmission member 2600.

[0058] The steps for adjusting the cup assembly include: the first power device 2500 alone can rotate the cup assembly 2100 to any position on the second support plate. Once the cup assembly 2100 has rotated to the preset position, the first power device 2500 can be stopped, and the second power device 2700 will start working, driving the external transmission component 2410 to rotate, the lower transmission component 2220 to rotate accordingly, driving the first support plate 2130 to rotate, thereby realizing the rotation of all cups.
