Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical production technology, and in particular to a drug mixing device for pharmaceutical production. Background Technology

[0002] Drugs are substances used to prevent, treat, or diagnose human diseases, or to purposefully regulate human physiological functions, and which have specified indications or therapeutic functions, usage, and dosage. They include traditional Chinese medicine, chemical drugs, and biological products. In the pharmaceutical manufacturing industry, it is usually necessary to mix drug powders with pharmaceutical preparations.

[0003] Currently, the mixing device requires manual quantitative weighing before the powder is added. Because the powder particles are small and light, they are easily scattered during weighing and adding, causing contamination. At the same time, the scattered powder can also lead to errors in the mixing process.

[0004] Therefore, to address the aforementioned problems, a drug mixing device for pharmaceutical production can be designed to quantitatively add the added drugs and powders without requiring manual weighing and quantification of the powders, thus reducing contamination and errors caused by powder scattering. Utility Model Content

[0005] To overcome the problem that current mixing devices still require manual weighing of the powder before feeding it in, which is prone to contamination due to the small size and light weight of the powder particles, and also causes errors in mixing and batching.

An electronic scale is integrated into the bottom surface of the feeding box, and a display is fixedly installed on one side of the feeding box. A connecting pipe is connected through the inside of the feeding box and is connected through the side wall of the discharge hopper. A filling port is connected through the upper end of the tank cover, and a flow valve is provided at the connection between the filling port and the tank cover. The stirring assembly is located inside the mixing tank, and the cleaning assembly is located below the tank cover.

[0007] Preferably, a stirring component can be installed to stir and mix the medicine in the mixing tank; a cleaning component can be installed to clean the mixing tank after the medicine is prepared; a dispensing interface can be installed to add liquid medicine to the mixing tank, and the amount of liquid medicine added can be controlled by a flow valve; a mounting bracket can be installed to support and install the feeding box; the feeding box can automatically weigh the medicine powder to be added and display it to the staff on a display screen; a rubber sleeve can be installed to cover the outside of the medicine powder packaging when adding medicine powder to the feeding box, sealing the inside of the feeding box and preventing medicine powder from scattering and polluting the environment and causing measurement errors. After the medicine powder is quantitatively measured, an external negative pressure device can be connected through an air interface to provide negative pressure to the connecting pipe, thereby drawing the medicine powder in the feeding box into the unloading hopper for air-powder separation, so that the medicine powder is added into the mixing tank to complete the medicine powder feeding.

[0008] Preferably, the stirring assembly includes a motor, a stirring shaft, and stirring blades. The motor is fixedly installed on the upper end of the bucket lid, the stirring shaft is fixedly installed on the output end of the motor, the stirring shaft passes through the bucket lid, and the stirring shaft and bucket lid are rotatably connected.

A mounting bracket 101 is fixedly installed on the side wall of the mixing tank 1, and a feeding box 102 is fixedly installed on the upper end of the mounting bracket 101. A rubber sleeve 103 is connected to one side of the feeding box 102. An electronic scale is integrated into the inner bottom surface of the feeding box 102. A display 104 is fixedly installed on one side of the feeding box 102. A connecting pipe 105 is connected through the inside of the feeding box 102, and the connecting pipe 105 is connected through to the side wall of the unloading hopper 201. A material injection port 203 is connected through to the upper end of the bucket cover 2. A flow valve 204 is provided at the connection between the material injection port 203 and the bucket cover 2. The stirring assembly is located inside the mixing bucket 1, and the cleaning assembly is located below the bucket cover 2. By setting the stirring assembly, the mixing can be cleaned. The medicines in the mixing tank 1 are stirred and mixed. A cleaning component can be set up to clean the mixing tank 1 after the medicine is prepared. A feeding port 203 can be set up to add liquid medicines to the mixing tank 1, and the amount of liquid medicines added is controlled by a flow valve 204. A mounting bracket 101 is set up to support and install the feeding box 102. The feeding box 102 can automatically weigh the medicine powder to be added and display it to the staff on a display 104. A rubber sleeve 103 can cover the outside of the medicine powder packaging when adding medicine powder to the feeding box 102, sealing the inside of the feeding box 102 to prevent the medicine powder from scattering and polluting the environment and causing measurement errors. After the medicine powder is quantitatively measured, an external negative pressure device can be connected through the air interface 202 to provide negative pressure to the connecting pipe 105, thereby drawing the medicine powder in the feeding box 102 into the unloading hopper 201 for air-powder separation, so that the medicine powder is added into the mixing tank 1 to complete the medicine powder feeding.

[0023] Please see Figure 1 and Figure 3In this embodiment, the stirring assembly includes a motor 301, a stirring shaft 302, and stirring blades 303. The motor 301 is fixedly installed on the upper end of the bucket cover 2, and the stirring shaft 302 is fixedly installed on the output end of the motor 301. The stirring shaft 302 passes through the bucket cover 2 and is rotatably connected to the bucket cover 2. Multiple sets of stirring blades 303 are fixedly installed around the stirring shaft 302. By setting the motor 301, the stirring shaft 302 can be driven to rotate, thereby driving the stirring blades 303 to rotate, and stirring and mixing the medicine in the mixing bucket 1. A connecting frame 304 is fixedly installed on the periphery of the stirring shaft 302. The connecting frame 304 and the stirring blade 303 are arranged alternately. A scraper 305 is fixedly installed on the upper end of the connecting frame 304. The scraper 305 contacts the inner wall of the mixing tank 1. The connecting frame 304 supports and installs the scraper 305. When the medicine in the mixing tank 1 is discharged, the connecting frame 304 rotates with the stirring shaft 302. The scraper can be used to clean the inner wall of the mixing tank 1 to prevent the medicine from sticking to the inner wall of the mixing tank 1 and causing waste.

[0024] Please see Figure 1 , Figure 2 and Figure 4 In this embodiment, the cleaning component includes a water inlet 401 and a sprayer 402. The water inlet 401 is installed through the upper end of the lid 2, and the sprayer 402 is fixedly installed at the lower end of the lid 2. The sprayer 402 is connected through the water inlet 401, and multiple sets of spray nozzles are provided at the lower end and around the periphery of the sprayer 402. By setting the water inlet 401 to connect to an external water source to supply water to the sprayer 402, clean water is sprayed out by the sprayer 402 to rinse and clean the inner wall of the mixing tank 1 and the stirring blades 303, etc., to prevent cross-contamination. Two sets of heating plates 501 are fixedly installed at the lower end of the mixing tank 1. The output end of the heating plate 501 is located inside the mixing tank 1, and a temperature sensor 502 is fixedly installed on the side wall of the mixing tank 1. By setting the temperature sensor 502, the temperature inside the mixing tank 1 can be monitored in real time, and the temperature is controlled by the heating plate 501. 1. The mixing tank 1 can be heated internally, dried internally after cleaning, and its temperature increased to improve mixing efficiency when preparing special medicines. An observation window 601 is embedded in the side wall of the mixing tank 1, and a scale line 602 is provided on the side wall of the mixing tank 1, located to one side of the observation window 601. The observation window 601 allows for easy observation of the medicine inside the mixing tank 1, and the scale line 602 allows for determination of the amount of medicine inside the mixing tank 1. A discharge pipe 701 is connected to the lower end of the mixing tank 1, and a discharge valve 702 is provided at the connection between the discharge pipe 701 and the mixing tank 1. The discharge valve 702 controls the discharge pipe 701, allowing the discharged medicine to be discharged after mixing.

[0025] During operation, liquid medicine can be added to the mixing tank 1 using the injection port 203, and the amount of liquid medicine added can be controlled by the flow valve 204. When feeding the powder, the outer packaging of the powder can be sealed to the inside of the feeding box 102, and then the powder is poured into the inside of the feeding box 102. The electronic scale integrated inside the feeding box 102 can weigh the amount of medicine, and the display 104 can display the amount of powder inside the feeding box 102 in real time.

[0026] Then, the external negative pressure device is connected through the air interface 202, and the negative pressure is provided to the connecting pipe 105 through the unloading hopper 201. The powder in the feeding box 102 is drawn into the unloading hopper 201 through the connecting pipe 105 for air-powder separation, so that the powder is added into the mixing tank 1 to complete the feeding of the powder. The amount of powder in the feeding box 102 is observed on the display 104. The powder can be quantitatively fed and the amount of powder fed can be automatically quantitatively measured. The relatively closed space inside the feeding box 102 can effectively prevent the powder from scattering and polluting the surrounding environment, and can also prevent the powder from scattering and causing the powder feeding error.

[0027] The motor 301 drives the stirring shaft 302 to rotate, which in turn drives the stirring blades 303 to rotate, thus mixing the medicine in the mixing tank 1. After the medicine is mixed, the discharge valve 702 controls the discharge pipe 701. The prepared medicine is discharged through the discharge pipe 701. The motor 301 is not turned off during the discharge process. The connecting frame 304 rotates with the stirring shaft 302, and the scraper can clean the inner wall of the mixing tank 1 to prevent the medicine from sticking to the inner wall of the mixing tank 1 and causing waste.

[0028] After the medicine is discharged, the water inlet 401 is connected to an external water source to supply water to the sprayer 402, so that the sprayer 402 sprays clean water to rinse and clean the inner wall of the mixing tank 1 and the stirring blades 303, etc., to prevent cross-contamination.

[0029] Through the above steps, liquid medicine can be quantitatively added through the injection port 203 and the flow valve 204. The rubber sleeve 103 can cover the outside of the powder packaging when adding powder to the feeding box 102, sealing the inside of the feeding box 102. This prevents the powder from scattering and polluting the environment and causing measurement errors when the powder is added to the inside of the feeding box 102. The air port 202 can be connected to an external negative pressure device to provide negative pressure to the connecting pipe 105, thereby drawing the powder in the feeding box 102 into the discharge hopper 201 for air-powder separation, so that the powder can be added into the mixing tank 1 to complete the powder feeding. This solves the problem that the current mixing device still requires manual quantitative weighing before adding powder. Because the powder particles are small and light, they are easy to scatter during weighing and feeding, causing pollution. At the same time, the scattered powder can also cause errors in mixing.

[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
