Description

Technical Field

[0001] The present invention relates to the technical field of drug preparation equipment, and in particular to a drug preparation device capable of accurately measuring and controlling temperature. Background Art

[0002] Existing drug preparation equipment has the problem of insufficient precision during operation. It is necessary to screw the screws on both sides at the same speed at the same time to ensure that the axes of the preparation barrel and the stirring mechanism are aligned. However, it is difficult to ensure accuracy during manual operation, which causes the position of the preparation barrel to be offset, affecting the stirring effect and reducing work efficiency.

[0003] Chinese patent CN219424248U discloses a chemotherapy drug preparation device, which is operated by a hinged box door and a fixedly installed handle on a box body. A fixed installation box is installed in the box body, and a preparation cylinder is placed on the installation box. There is a cavity in the installation box, and two sliders are slidably installed in the cavity. A rotating shaft is rotatably installed on the lower surface of the installation box, and a rotating handle is fixedly installed on the top of the rotating shaft extending into the cavity of the installation box. Connecting rods are rotatably installed on both sides of the rotating handle, and the end of the connecting rod away from the rotating handle is rotatably connected to the slider on the same side. A plurality of connecting columns are fixedly installed on the slider, and a matching connecting rod is provided on the upper surface of the installation box. The tops of several connecting columns on the same displacement slider all pass through the slide and are fixedly installed with the same mounting plate. Clamping plates are fixedly installed on the opposite surfaces of the two mounting plates. A driving component is arranged on the lower surface of the mounting box. An electric push rod is fixedly installed on the upper surface of the inner wall of the box body. A mounting frame is fixedly installed on the end of the piston rod of the electric push rod. A cover plate is fixedly installed on the mounting frame. A mixing component is arranged on the cover plate. The rotation of the rotating shaft drives the rotation of the rotating handle. The rotation of the rotating handle drives the sliders on both sides to approach each other through the connecting rods on both sides. The movement of the slider drives the clamping block to move, thereby driving the clamping plates on both sides to approach each other to configure the cylinder. The clamping is fixed, and the clamping stability is good. The displacement of the clamping blocks on both sides is the same, so that the axis of the configuration barrel is always located on the central axis of the stirring shaft, which is convenient for subsequent stirring operations, simple operation and easy to use; the driving component includes a worm rotatably mounted on the mounting box, a worm wheel used in conjunction with the worm is fixedly mounted on the outer surface of the rotating shaft, and a handwheel is fixedly mounted on one end of the worm; the mixing component includes a reduction motor fixedly mounted on the cover plate, a stirring shaft is rotatably mounted on the cover plate, the top end of the stirring shaft is fixedly connected to the output end of the reduction motor, a gear 1 is fixedly mounted on the outer surface of the stirring shaft, a gear 2 is meshed on the gear 1, and a handwheel is fixedly mounted on the lower surface of the cover plate A gear ring meshing with gear two is fixedly installed, and a connecting shaft is fixedly installed on gear two. The reduction motor drives the stirring shaft to rotate to stir the materials in the configuration barrel. When the stirring shaft rotates, it drives gear two to rotate through gear one and the gear ring. The rotation of gear two drives the connecting shaft to rotate, so that the connecting shaft can rotate around the rotating shaft at different speeds to stir the materials in the configuration barrel. Then the electric push rod is extended and retracted to drive the cover plate to move up and down, so that the stirring shaft and the connecting shaft can stir and mix the materials at different heights and positions in the configuration barrel. The stirring methods are diverse, the stirring is sufficient, and the mixing efficiency is high.

[0004] The device in the patent document does not precisely control the temperature inside the mixing device, but some drugs have extremely strict temperature requirements, so a mixing device that strictly controls the temperature is needed. In addition, during the configuration process, it is very likely that some drugs will remain on the inner wall of the mixing device. If the drugs attached to the inner wall cannot be cleaned in time, it will affect the next mixing. Summary of the invention

Through the precise control of the temperature control component, the drug can be prevented from becoming ineffective due to temperature fluctuations, ensuring the stability and effectiveness of the drug throughout the preparation process, thereby improving the safety and reliability of the drug.

[0019] 3. The pretreatment mechanism of the present invention realizes the preliminary crushing of the drug through the design of the crushing box and the crushing roller, which has a significant effect on improving the dissolution rate and bioavailability of the drug. The drug can dissolve more quickly after crushing, so that the drug components can be more effectively absorbed by the patient. In addition, the design of the diversion pipeline enables the crushed drug particles to be smoothly transferred to the heat conduction tank, further improving the efficiency and automation of drug configuration, and reducing the tediousness of manual operation and potential errors.

DETAILED DESCRIPTION

[0032] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] Reference Figure 1-Figure 11 As shown: A drug preparation device with precise temperature measurement and control, comprising a mixing mechanism 1 and a supporting mechanism 2, wherein the mixing mechanism 1 comprises a heat conduction tank body 11 for preparing drugs, a stirring rod 12 is arranged inside the heat conduction tank body 11, a scraper assembly 13 is arranged around the stirring rod 12 and is in contact with the inner wall of the heat conduction tank body 11, a supporting mechanism 2 is arranged outside the heat conduction tank body 11, the supporting mechanism 2 comprises a clamping block 21 for clamping the heat conduction tank body 11, and a temperature control assembly for adjusting the internal temperature of the heat conduction tank body 11 is arranged inside the clamping block 21.

[0034] In the drug preparation device of the prior art, the inner wall of the mixing device is not cleaned, and part of the mixed drugs will adhere to the inner wall of the mixing device to cause drug residue. In view of this, in the present invention, the temperature control component can adjust the temperature of the clamping block 21, and the clamping block 21 can conduct the adjusted temperature to the inside through the heat conduction tank body 11, so as to provide a constant temperature for the internal drug preparation. The heat conduction tank body 11 is provided with a stirring rod 12 inside, and the stirring rod 12 is used to stir the drugs located inside the heat conduction tank body. A scraper assembly 13 that can rotate with the stirring rod 12 is provided around the stirring rod 12, and the scraper assembly 13 is in contact with the inner wall of the heat conduction tank body 11. When the stirring rod 12 drives the scraper assembly 13 to rotate, the scraper assembly 13 will scrape off the drugs adhered to the heat conduction tank body 11 during the stirring process to avoid drug residue. In addition, the device allows the drugs to maintain a constant temperature during the preparation process, which is particularly important for certain temperature-sensitive drugs, such as heat-sensitive biological agents or chemical drugs that need to remain active at a specific temperature. Through this device, the quality and safety of drug preparation can be improved, ensuring the efficacy of drugs and the safety of patients' medication.

[0035] Reference Figure 1-Figure 6 As shown: the scraper assembly 13 includes a bottom turntable 131 arranged at the tail of several scrapers, the bottom turntable 131 is provided with a through hole for the stirring rod 12 to pass through, a limiting hole 132 is provided around the through hole of the bottom turntable 131, and the tail of the stirring rod 12 is provided with a limiting block 121 that is plugged into the limiting hole 132.

[0036] The scraper assembly 13 is composed of a scraper and a bottom turntable 131. The bottom turntable 131 can drive the scraper to rotate around the axis of the stirring rod 12. A limit block 121 is provided at the tail of the stirring rod 12. A limit hole 132 adapted to the model of the limit block 121 is opened on the bottom turntable 131. The limit block 121 at the tail of the stirring rod 12 is inserted into the limit hole 132 of the bottom turntable 131. Under the limitation of the limit block 121 on the limit hole 132, the stirring rotation will drive the bottom turntable 131 to rotate together. The rotation of the bottom turntable 131 drives the scraper to rotate. During the rotation of the scraper, the medicine attached to the inner wall of the heat conduction tank body 11 will be scraped off to avoid the medicine remaining on the inner wall of the heat conduction tank body 11. Through this structural design, the accuracy and uniformity of the medicine configuration process can be improved to ensure the quality and efficacy of the medicine.

[0037] Reference Figure 7-Figure 11 As shown: the support mechanism 2 includes a storage platform 22 arranged above the heat conduction tank body 11, and a control mechanism 3 for adjusting the temperature control component is arranged above the storage platform 22. The control mechanism 3 is provided with a display screen 32 for displaying the internal temperature of the heat conduction tank body 11 and the set temperature of the temperature control component, and a control button 31 for adjusting the temperature of the temperature control component is arranged below the display screen 32.

[0038] The support mechanism 2 includes a storage platform 22 located above the heat transfer tank 11. A control mechanism 3 is provided above the storage platform 22. The control mechanism 3 is responsible for adjusting the temperature control component. The control mechanism 3 is provided with a display screen 32 for real-time display of the actual temperature inside the heat transfer tank 11 and the target set temperature of the temperature control component. Control buttons 31 are provided below the display screen 32. These buttons allow the user to adjust and set the working temperature of the temperature control component as needed, thereby achieving precise control of the temperature during the drug preparation process.

[0039] Reference Figure 7-Figure 11 As shown: a pretreatment mechanism 4 for crushing the medicine is arranged above the storage platform 22, and the pretreatment mechanism 4 includes a plurality of crushing boxes 41 arranged above the storage platform 22, and a crushing roller 42 for crushing the medicine in the crushing box 41 is arranged in the crushing box 41.

[0040] The pretreatment mechanism 4 equipped above the storage platform 22 is mainly used for the crushing of drugs to ensure the full release and uniform dispersion of drug components. The pretreatment mechanism 4 includes a plurality of crushing boxes 41, which are used to accommodate drugs that need to be crushed. Inside each crushing box 41, a crushing roller 42 is installed, which is used to crush and grind the drugs. When the drug is placed in the crushing box 41, the crushing roller 42 crushes the drug into finer particles by applying pressure and grinding. This process helps to extract the drug components and enables the drug to be dissolved or mixed faster and more evenly in the subsequent configuration process. Through the crushing process of the pretreatment mechanism 4, the dissolution rate and bioavailability of the drug can be significantly improved, ensuring the quality and efficacy of the drug configuration.

[0041] Reference Figure 2 As shown: a guide pipe 411 is provided between the crushing box body 41 and the heat conduction tank body 11.

[0042] The guide pipe 411 between the crushing box body 41 and the heat transfer tank body 11 plays a role in transferring drug particles. One end of the guide pipe 411 is connected to the discharge port 5 of the crushing box body 41, and the other end is connected to the feed port of the heat transfer tank body 11, ensuring that the drug particles can flow directly from the crushing box body 41 into the heat transfer tank body 11. The design of the guide pipe 411 ensures that the drug particles can continuously and smoothly enter the heat transfer tank body 11, avoiding manual intervention and improving the efficiency and automation of the entire drug preparation process.

[0043] Reference Figure 7-Figure 11 As shown, a guide groove 43 for guiding medicine is provided above the crushing roller 42 in the pulverizing box body 41 , and a feeding port 44 is provided at the center of the guide groove 43 .

[0044] A guide groove 43 is provided above the crushing roller 42 in the crushing box 41, and the guide groove 43 guides the medicine to be crushed to the top of the crushing roller 42 for effective crushing. The medicine is added from the upper part of the guide groove 43, guided by gravity, and slides down the guide groove 43 to the discharge port 44 at the center. When the medicine reaches the discharge port 44 and enters the action area of ​​the crushing roller 42 through the discharge port 44, the crushing roller 42 applies pressure to crush the medicine. The guide groove 43 can prevent the drug powder from splashing or scattering during the crushing process, keep the crushing box 41 clean, and ensure the hygiene and safety of the drug crushing process. The discharge port 44 ensures that the drug powder can fall smoothly, avoids blockage, and ensures the continuity of the crushing process and the consistency of the crushing effect.

[0045] Reference Figure 1-Figure 11 As shown, a cover body 45 is provided on the top of the crushing box body 41 .

[0046] The cover 45 above the crushing box 41 is designed to close the upper part of the crushing box 41 to protect the crushing process and the safety of the operator. In addition, the presence of the cover 45 helps to reduce the flying of drug powder during the crushing process, keep the working environment clean, and avoid cross contamination.

[0047] Reference Figure 7-Figure 11 As shown: a handle 451 is provided above the cover body 45 for the operator to hold.

[0048] The handle 451 can prevent the operator from getting burned when the pulverizing box body 41 is operated at high temperature, thereby protecting the operator's safety.

[0050] The prepared medicine flows out through the discharge port 5 and is received by a storage device below the discharge port 5. The storage device may be a storage bottle or other device for receiving medicine.

[0051] Reference Figure 1-Figure 11 As shown: a closing block 51 is hinged below the discharge port 5.

[0052] The sealing state of the discharge port 5 can be changed by the sealing block 51. When the medicine is being prepared, the discharge port 5 is blocked by the sealing block 51 to prevent the contents of the heat conduction tank 11 from flowing out. When the preparation is completed, the sealing block 51 is removed to open the discharge port 5 to discharge the medicine.

[0053] The working principle of the drug dispensing device with precise temperature measurement and temperature control involves the coordinated work of multiple components to ensure the accuracy and efficiency of drug dispensing. The core of the device is the heat conduction tank 11, which is used to dispense drugs and is provided with a stirring rod 12 and a scraper assembly 13 inside. The stirring rod 12 is used to stir the drugs, while the scraper assembly 13 fits the inner wall to scrape off the attached drugs to prevent residue. The clamping block 21 on the outside of the heat conduction tank 11 is provided with a temperature control assembly, which can adjust the temperature and keep the temperature of the drug dispensing constant through heat conduction, which is particularly important for heat-sensitive drugs. The scraper assembly 13 includes a bottom turntable 131 and a limit block 121. The bottom turntable 131 drives the scraper to rotate, and the limit block 121 ensures that the scraper is correctly positioned to improve the uniformity of drug dispensing. A control mechanism 3 is provided above the storage platform 22 of the support mechanism 2, equipped with a display screen 32 and a control button 31, which is used to monitor and adjust the temperature of the heat conduction tank 11 in real time. The pretreatment mechanism 4 is arranged above the storage platform 22, and includes a crushing box body 41 and a crushing roller 42, which are used for preliminary crushing of the drug to ensure the full release of the drug components. The crushing box body 41 is connected to the heat conduction tank body 11 through a guide pipe 411 to achieve smooth transfer of drug particles. A guide groove 43 and a discharge port 44 are provided above the crushing roller 42 in the crushing box body 41 to guide the drug to the crushing roller 42 for crushing, ensuring the continuity and consistency of the crushing process. The cover body 45 above the crushing box body 41 closes the upper part to protect the safety of the operator and reduce the flying of drug powder. The handle 451 above the cover body 45 is designed to facilitate the operator to carry and position the crushing box body 41. The discharge port 5 below the heat conduction tank body 11 is used for the outflow of the drug, and the closing block 51 below the discharge port 5 can control the opening and closing of the discharge port 5 to prevent the drug from flowing out during the configuration process. After the configuration is completed, the closing block 51 is removed to export the drug. The entire device is designed to improve the quality and safety of drug preparation, ensuring drug efficacy and patient safety, especially for temperature-sensitive drugs. Through automation and precise temperature control, the device can ensure that the drug remains in optimal condition throughout the preparation process.
