Description

Technical Field

[0001] This invention relates to the field of medical auxiliary equipment technology, and in particular to an adjustable quantitative mixing device for oral suspensions for children. Background Technology

[0002] Oral suspensions are common medications for children, such as solid dry suspensions like amoxicillin, cefaclor, and azithromycin. These medications usually need to be mixed with a solvent before administration. However, because children's physiological functions are not yet fully developed, the dosage and concentration of the medication must be precisely controlled based on the child's age, weight, and condition. The accuracy of the drug concentration directly affects the therapeutic effect and medication safety.

[0003] Currently, the preparation of oral suspensions for children mostly relies on manual operation by parents or medical staff. This manual method has several problems. On the one hand, the manual preparation process is cumbersome, and people often rely on their own intuition to control the drug concentration, leading to a significant difference between the final drug concentration and the ideal concentration. Both excessively high and low drug concentrations can affect the therapeutic effect. On the other hand, dry suspensions have low solubility in solvents, and manual preparation lacks effective stirring methods, which may result in uneven dispersion of suspension particles, clumping, and sedimentation, affecting the child's absorption of the drug. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a drug concentration adjustable quantitative mixing device for children's oral suspensions, in order to solve the problems mentioned in the background art, that the existing mixing methods for children's oral suspensions are cumbersome and the mixing concentration cannot be guaranteed.

[0005] The present invention solves the above-mentioned technical problems through the following technical means:

[0027] The baffle plate is installed on the end of the sleeve away from the third drive motor. The baffle plate is provided with a first baffle for covering the discharge port, and a second baffle and a third baffle for covering the liquid outlet.

[0054] Example 1

[0055] like Figure 1-4 As shown in the figure, this application provides a drug concentration adjustable quantitative mixing device for oral suspensions for children, including a base 100, a shell 200, a suspension delivery mechanism, a solvent delivery mechanism, a stirring mechanism, and a main control module 600.

[0056] The base 100 has a hollow cavity in its center, open at the top. A mixing cup 110 is detachably installed in this cavity. The mixing cup 110 is used to contain the suspension and solvent and to mix them. A weighing sensor 120 is installed between the bottom of the mixing cup 110 and the base 100 to monitor the weight of the mixing cup 110.

[0057] The housing 200 is detachably mounted on the upper side of the base 100. Specifically, the housing 200 can be detachably mounted on the base 100 via snap-fit ​​connection, magnetic connection, or threaded connection. Furthermore, a downwardly extending positioning ring 210 is provided on the lower side of the housing 200. This positioning ring 210 can be fitted onto the base 100 to assist in the installation and positioning of the housing 200 and the base 100. When the housing 200 is installed on the base 100, the bottom of the housing 200 can seal the open end of the mixing cup 110. The housing 200 also houses a suspension storage tank 220 and a solvent storage tank 230. The suspension storage tank 220 is used to store dry suspensions, primarily solid powdered drugs, while the solvent storage tank 230 is used to store solvents, primarily water.

[0058] To facilitate the addition of suspension agents and solvents, the upper end of the suspension storage tank 220 extends to the upper side of the housing 200 and is detachably fitted with a first cover 221; the upper end of the solvent storage tank 230 extends to the upper side of the housing 200 and is detachably fitted with a second cover 231. Both the first cover 221 and the second cover 231 can be detachably installed on their respective storage tanks using snap-fit ​​connections, magnetic connections, or threaded connections.

[0059] The bottom side of the shell 200 is provided with a discharge port 240 and a liquid outlet 250. Both the discharge port 240 and the liquid outlet 250 are located directly above the open end of the mixing cup 110. The discharge port 240 is used to discharge the suspension, and the liquid outlet 250 is used to discharge the solvent.

[0060] The suspension conveying mechanism is used to transport the suspension in the suspension storage tank 220 to the mixing cup 110. The suspension conveying mechanism adopts an electrically driven structure, which can connect the bottom of the suspension storage tank 220 to the discharge port 240, thereby inputting the suspension in the suspension storage tank 220 into the mixing cup 110. In order to facilitate the discharge of the suspension storage tank 220, the bottom of the suspension storage tank 220 is designed in a funnel shape.

[0061] The solvent delivery mechanism is used to deliver the solvent in the solvent storage tank 230 to the mixing cup 110. The solvent delivery mechanism also adopts an electrically driven structure, which can connect the bottom of the solvent storage tank 230 to the outlet 250, thereby inputting the solvent in the solvent storage tank 230 into the mixing cup 110.

[0062] The stirring mechanism also adopts an electrically driven structure to stir the suspension and solvent in the mixing cup 110, so that the suspension is evenly dispersed in the solvent, reducing problems such as uneven dispersion, clumping and sedimentation of suspension particles, thereby improving the therapeutic effect.

[0063] The main control module 600 is electrically connected to the weighing sensor 120, the suspension delivery mechanism, the solvent delivery mechanism, and the stirring mechanism. The main control module 600 mainly consists of a control chip (such as an STM32 or ESP32) and a drive module. It can acquire monitoring data from the weighing sensor 120 and control the operation of the weighing sensor 120, the suspension delivery mechanism, the solvent delivery mechanism, and the stirring mechanism according to a preset algorithm. In addition, a display screen 261 and several buttons 262 are also installed on the housing 200, and the display screen 261 and buttons 262 are electrically connected to the main control module 600. Users can set the amounts of suspension and solvent according to actual needs.

[0064] Through the above technical solution, when the user operates, firstly, the sampling amounts of the suspension and solvent are set according to the actual situation; then, the main control module 600 controls the suspension delivery mechanism to work, inputting the suspension in the suspension storage tank 220 into the mixing cup 110; at the same time, the main control module 600 acquires the weight data of the mixing cup 110 in real time, and calculates the weight of the suspension in the mixing cup 110 using the difference method, that is, the weight of the suspension in the mixing cup 110 is equal to the weight at the current moment minus the weight at the initial moment; when the weight difference of the mixing cup 110 reaches the preset amount of suspension, the suspension delivery mechanism stops working, and the solvent delivery mechanism starts working, and the solvent sampling is also calculated using the difference method; when the weight difference of the mixing cup 110 reaches the preset amount of solvent, the solvent delivery mechanism stops working, and the stirring mechanism starts working, thereby stirring the suspension and solvent evenly; finally, the shell 200 is removed, and the mixing cup 110 is taken out from the base 100.

[0065] This design not only makes it easier for users to prepare suspensions of any concentration according to actual conditions, but also improves the automation of the suspension preparation process. At the same time, it can reduce the error between the actual concentration and the ideal concentration of the suspension, thereby ensuring the therapeutic effect of the drug.

[0066] It should be noted that the solvent in this embodiment is mainly water. While solvent sampling is typically measured in volume units, this embodiment uses weight difference to calculate the solvent sampling volume. This only requires a volume-to-weight conversion within the preset algorithm of the main control module 600. Users should still set the solvent sampling volume using volume, for example, setting it to 10ml.

[0067] In this embodiment, the suspension delivery mechanism includes a transmission pipe 310, a helical blade 320, and a first drive motor 330 installed within the housing 200. The transmission pipe 310 has an inlet 311 and an outlet 312. The inlet 311 communicates with the lowest point of the bottom funnel structure of the suspension storage tank 220, and the end of the outlet 312 away from the transmission pipe 310 is inserted into the outlet 240. The helical blade 320 is rotatably mounted within the transmission pipe 310. The first drive motor 330 is electrically connected to the main control module 600, and the output shaft of the first drive motor 330 is fixedly connected to the rotating shaft of the helical blade 320.

[0068] During the transport of the suspension, the suspension in the storage tank 220 leaks into the transport pipe 310 through the inlet 311. The main control module 600 then controls the first drive motor 330 to operate, thereby driving the spiral blades 320 to rotate, thus transporting the suspension through the outlet pipe 312 and the outlet 240 to the mixing cup 110. This method of transporting the suspension makes it easier to accurately control the sampling amount.

[0069] In this embodiment, the solvent delivery mechanism includes a pump body 410, a solvent inlet pipe 420, and a solvent outlet pipe 430, all installed within the housing 200. The pump body 410 is electrically connected to the main control module 600. One end of the solvent inlet pipe 420 is connected to the inlet end of the pump body 410, and the other end is connected to the solvent storage tank 230. One end of the solvent outlet pipe 430 is connected to the outlet end of the pump body 410, and the other end is inserted into the outlet 250. During solvent delivery, the main control module 600 controls the pump body 410 to operate, thereby delivering the volume from the solvent storage tank 230 to the mixing cup 110.

[0070] In another embodiment, the solvent delivery mechanism can also employ a piston structure in conjunction with a drive cylinder to add solvent, with the drive cylinder propelling the piston to push the solvent into the mixing cup 110.

[0071] In this embodiment, the stirring mechanism includes a second drive motor 510 and a stirring rod 520 installed within the housing 200. The second drive motor 510 is electrically connected to the main control module 600. The stirring rod 520 is rotatably installed within the housing 200. Its upper end is fixedly connected to the output shaft of the second drive motor 510, and its lower end extends through the bottom side of the housing 200 into the mixing cup 110. A stirring blade 521 is installed at the lower end of the stirring rod 520. When mixing the suspension and solvent, the main control module 600 controls the second drive motor 510 to operate, thereby driving the stirring rod 520 to rotate, thus stirring and mixing the suspension and solvent within the mixing cup 110.

[0072] In addition, it should be noted that, in order to prevent the suspension from falling onto the stirring blade 521 during the delivery of the suspension, which would cause errors in the sampling amount of the suspension, the outlet 240 is not in the same vertical position as the stirring blade 521. The outlet 240 is closer to the cup wall of the mixing cup 110, while the stirring blade 521 is closer to the center of the mixing cup 110.

[0073] In another embodiment, the suspension and solvent in the mixing cup 110 can also be stirred and mixed by means of vibration stirring, magnetic stirring, etc.

[0074] Example 2

[0075] like Figure 1-7 As shown, the device in this embodiment, in addition to having all the structures in Embodiment 1, also includes an outlet blocking mechanism. The outlet blocking mechanism includes a third drive motor 710, a sleeve 720, and a blocking plate 730. The third drive motor 710 is installed inside the housing 200 and electrically connected to the main control module 600. The sleeve 720 is rotatably installed inside the housing 200 via a bearing 721 and is fitted over a portion of the structure of the stirring rod 520. The rotation of the sleeve 720 and the rotation of the stirring rod 520 do not interfere with each other.

[0076] In this embodiment, one end of the sleeve 720 is connected to the output shaft of the third drive motor 710. Specifically, the sleeve 720 and the third drive motor 710 are connected by gear transmission. A driving gear 711 is mounted on the output shaft of the third drive motor 710, and a driven gear 722 is mounted on the sleeve 720. The driven gear 722 meshes with the driving gear 711. In another embodiment, the sleeve 720 and the third drive motor 710 can also be connected by belt transmission or other methods.

[0077] The end of the sleeve 720 away from the third drive motor 710 penetrates the bottom side of the housing 200, while the baffle plate 730 is fixedly installed on the end of the sleeve 720 away from the third drive motor 710. The baffle plate 730 is provided with a first baffle portion 731 for sealing the discharge port 240, and a second baffle portion 732 and a third baffle portion 733 for sealing the liquid outlet 250. The three baffle portions 732 are distributed on the circumference of the baffle plate 730, and the coverage area of ​​the first baffle portion 731 is larger than that of the second baffle portion 732 and the third baffle portion 733.

[0078] When the suspension is not needed, the main control module 600 can control the third drive motor 710 to work, so that the first shielding part 731 rotates to the position of sealing the outlet 240. This not only prevents residual suspension from the outlet 240 from falling into the mixing cup 110 and affecting the concentration of the suspension, but also prevents liquid in the mixing cup 110 from splashing onto the outlet 240 and affecting the unused suspension. It also has a certain moisture-proof effect.

[0079] When solvent delivery is not required, the main control module 600 can control the third drive motor 710 to operate, causing the second shielding part 732 or the third shielding part 733 to rotate to the position of sealing the outlet 250. This not only prevents residual solvent from the outlet 250 from falling into the mixing cup 110 and affecting the concentration of the suspension, but also prevents liquid in the mixing cup 110 from splashing onto the outlet 250 and affecting the unused solvent.

[0080] To achieve a more intelligent protection effect, this embodiment formulates a protection strategy for the exit blocking mechanism. Under the drive of the third drive motor 710, the blocking plate 730 has a first position, a second position, and a third position. The specific details of these three positions are described below:

[0081] (1) such as Figure 5 As shown, when the baffle plate 730 is rotated to the first position, the first baffle part 731 does not cover the discharge port 240, the second baffle part 732 covers the liquid outlet 250, and the third baffle part 733 does not contact the liquid outlet 250. In this case, the device only delivers the suspension into the mixing cup 110.

[0082] (2) such as Figure 6 As shown, when the baffle 730 is in the second position, the first baffle 731 covers the discharge port 240, and the second baffle 732 and the third baffle 733 do not cover the liquid outlet 250. The liquid outlet 250 is located in the gap between the second baffle 732 and the third baffle 733. In this case, the device only delivers the solvent to the mixing cup 110.

[0083] (3) such as Figure 7 As shown, when the baffle plate 730 is in the third position, the first baffle part 731 covers the discharge port 240, the second baffle part 732 does not contact the liquid outlet 250, and the third baffle part 733 covers the liquid outlet 250. In this case, the device will not deliver suspension or solution. At this time, the solution can be stirred, or the mixing cup 110 can be removed, etc.

[0084] The three positions can be determined using the number of rotations of the output shaft of the third drive motor 710. For example, if the baffle 730 is initially in the first position, after the output shaft of the third drive motor 710 rotates one revolution, the baffle 730 will rotate from the first position to the second position. After the output shaft of the third drive motor 710 rotates another revolution, the baffle 730 will rotate from the second position to the third position. This design facilitates the position control of the baffle 730. In this embodiment, the default initial position of the baffle 730 is set to the third position.

[0085] Through the above technical solution, when the user operates, firstly, the sampling amounts of suspension and solvent are set according to the actual situation; then, the main control module 600 controls the third drive motor 710 to work, causing the baffle 730 to rotate from the third position to the first position. In this case, the discharge port 240 is in the open state, and the liquid outlet 250 is in the closed state; then, the main control module 600 controls the suspension conveying mechanism to work, inputting the suspension in the suspension storage tank 220 into the mixing cup 110; at the same time, the main control module 600 acquires the weight data of the mixing cup 110 in real time, and calculates the weight of the suspension in the mixing cup 110 using the difference method; when the weight difference of the mixing cup 110 reaches the preset amount of suspension, the suspension conveying mechanism stops working; then, the main control module 600 controls the third drive motor 710 to work. The main control module 600 operates by rotating the baffle 730 from the first position to the second position, in which case the discharge port 240 is closed and the liquid outlet 250 is open. Then, the main control module 600 controls the solvent delivery mechanism to start working, delivering the solvent into the mixing cup 110. When the weight difference in the mixing cup 110 reaches the preset amount of solvent, the solvent delivery mechanism stops working. Then, the main control module 600 controls the third drive motor 710 to work, causing the baffle 730 to rotate from the second position to the third position, in which case both the discharge port 240 and the liquid outlet 250 are closed. Then, the main control module 600 controls the stirring mechanism to start working, thereby stirring the suspension and solvent evenly. Finally, the housing 200 is removed, and the mixing cup 110 is taken out from the base 100.

[0086] This design blocks the solvent outlet 250 when the suspension is being transported, blocks the suspension outlet 240 when the solvent is being transported, and blocks both the outlet 250 and the outlet 240 during stirring. This provides better protection for the volume of the suspension at the outlet 240 and the outlet 250, and prevents cross-interference between the mixture, suspension, and solvent during transport or stirring, thereby reducing the concentration error of the suspension in the mixture.

[0087] Example 3

[0088] like Figure 1-7 As shown, the device in this embodiment, in addition to having all the structures described in Embodiment 2, also includes a human-computer interaction unit, which includes a voice module 810, a microphone 820, and a speaker 830. The voice module 810, microphone 820, and speaker 830 are all installed within the housing 200. The microphone 820 and speaker 830 are electrically connected to the voice module 810, and the voice module 810 is electrically connected to the main control module 600.

[0089] Through the human-computer interaction unit, users can directly speak the required suspension sampling amount and solvent sampling amount via voice control. The human-computer interaction unit can collect the user's voice information through the microphone 820, and then output it to the voice module 810 to convert it into specific control commands, which are then transmitted to the main control module 600. The main control module 600 executes the commands, while the speaker 830 can respond with the completion status of the corresponding commands.

[0090] It should be noted that the voice module 810 can convert the user's voice information into corresponding control commands. These are all relatively mature existing technologies, and the relevant technologies will not be described in detail in this embodiment.

[0091] Furthermore, the human-computer interaction unit can connect to or deploy mainstream AI voice models (such as Doubao and Qianwen) locally. This design not only enables the device to execute commands but also allows for interactive question-and-answer sessions and daily communication with the user. This design makes the device more convenient and intelligent.
