Technical Field

[0001] This utility model relates to the field of pharmaceutical processing technology, and more specifically, to a pharmaceutical crushing and mixing device for pharmacy departments. Background Technology

[0002] In clinical practice, different patients have varying needs for medication dosage and formulation due to differences in age, weight, and disease condition. The pharmacy department can customize medications according to each patient's specific needs by pulverizing and mixing them. For example, children's swallowing function is not fully developed; for some large tablets that are difficult to swallow, pulverizing them and mixing them with appropriate excipients can create palatable and easy-to-swallow suspensions or granules, making them convenient for children to take while ensuring efficacy. For elderly people with multiple diseases who need to take multiple medications simultaneously, pulverizing and mixing these medications in appropriate proportions to create compound preparations can reduce the frequency of dosing and improve patient adherence.

[0003] In pharmacy departments, granular medications often need to be pulverized and mixed according to patients' conditions. Currently, most pulverizing and mixing devices are designed for batch processing, pulverizing large quantities of medication at a time. This makes them unsuitable for pulverizing and mixing just a few granules at a time, hindering the pharmacy department's ability to effectively pulverize and mix medications. Therefore, we propose a dedicated pulverizing and mixing device for pharmacy departments. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a special medicine pulverizing and mixing device for pharmacy departments, so as to solve the current technical problem of poor adaptability for pulverizing and mixing a few medicines at a time, which is not conducive to the use of medicine pulverizing and mixing in pharmacy departments.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a pharmaceutical department-specific drug pulverizing and mixing device, comprising a pulverizing cylinder, a pulverizing pestle disposed inside the pulverizing cylinder, and a mixing mechanism disposed on the pulverizing pestle. The upper part of the pulverizing cylinder is straight, the lower part of the pulverizing cylinder is hemispherical, the upper end of the pulverizing cylinder is open, and a threaded cap is installed on the upper end of the pulverizing cylinder. The pulverizing pestle includes a connecting rod disposed on the threaded cap, a mortar ball is installed at the lower end of the connecting rod, an exhaust plate is disposed on the connecting rod above the mortar ball, an air blowing box is installed at the upper end of the connecting rod, and a handle is installed at the upper end of the air blowing box. The mixing mechanism includes a sleeve shaft rotatably mounted on the outside of the connecting rod and a drug loading cylinder disposed on the connecting rod.

[0006] Preferably, the threaded cover has a movable hole at the center of its upper end, the connecting rod and the sleeve shaft are located in the movable hole, and the size of the sleeve shaft is adapted to the size of the movable hole. The threaded cover has an air outlet, and a baffle net is provided in the air outlet.

[0007] Preferably, the connecting rod is hollow, the exhaust plate has a cavity, the lower end of the exhaust plate has an array of air outlet holes, and the two ends of the connecting rod are respectively connected to the exhaust plate and the blower box.

[0008] Preferably, a micro motor is provided inside the blower box, a fan blade is installed at the end of the output shaft of the micro motor, and an array of air inlets are opened on the outer surface of the blower box.

[0009] Preferably, a windmill blade is mounted on the sleeve shaft, the windmill blade is located above the threaded cover, and a fixing rod is arranged in an array on the lower outer surface of the sleeve shaft, with a stirring rod installed at the end of the fixing rod.

[0010] Preferably, the upper end of the charging cylinder is open, the charging cylinder is in the shape of a trumpet opening outward from bottom to top, air passages are arranged in an array at the upper edge of the charging cylinder, and the stirring rod is located inside the charging cylinder.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, through the design of a pulverizing pestle structure, allows the user to complete the pulverizing of medicines by repeatedly moving the pulverizing pestle up and down with the handle. During the pulverizing process, in conjunction with structures such as fan blades and windmill blades, the pulverized medicines can be screened and mixed. It can be used for pulverizing and mixing small amounts of medicines (a few pills), which better meets the actual needs of pharmacy departments for processing small amounts of medicines. It solves the problem that the current device has poor adaptability to pulverizing and mixing a few pills at a time, which is not conducive to the use of pulverized and mixed medicines in pharmacy departments.

[0013] 2. This utility model also designs a drug-filling cylinder structure. The air passage on the drug-filling cylinder forms a dedicated airflow channel. After the airflow passes through the air passage, the airflow can be dispersed. Because the drug-filling cylinder is trumpet-shaped with a large opening at the top, combined with the intermittent operation of the motor, the pulverized medicine can easily pass through the air passage along the outer surface of the drug-filling cylinder and enter the drug-filling cylinder, thereby facilitating the mixing of the medicine.

[0014] 3. This utility model also incorporates a fan blade and a windmill blade structure. The fan blades, combined with the motor drive, create a downward airflow that can screen and convey the pulverized medicine upwards, allowing it to enter the medicine loading cylinder and preventing the medicine from accumulating at the bottom of the cylinder and affecting the pulverization effect. Furthermore, the airflow can also drive the windmill blades to rotate the shaft, thereby mixing the pulverized medicine with the stirring rod. This ingenious use of the same airflow achieves the screening, conveying, and mixing of the medicine powder, simplifying the equipment structure, reducing energy consumption, and ensuring the thoroughness and uniformity of the medicine powder mixing.

Detailed Implementation

[0020] like Figures 1 to 4 As shown, this utility model relates to a pharmaceutical department-specific drug pulverizing and mixing device, including a pulverizing cylinder 101, a pulverizing pestle 200 disposed inside the pulverizing cylinder 101, and a mixing mechanism 300 disposed on the pulverizing pestle 200. The upper part of the pulverizing cylinder 101 is cylindrical, the lower part of the pulverizing cylinder 101 is hemispherical, and the upper end of the pulverizing cylinder 101 is open. A threaded cap 102 is installed on the upper end of the pulverizing cylinder 101. The pulverizing pestle 200 includes a connecting rod 201 disposed on the threaded cap 102. A mortar ball 202 is installed on the lower end of the connecting rod 201. An exhaust plate 203 is disposed on the connecting rod 201 above the mortar ball 202. An air blowing box 204 is installed on the upper end of the connecting rod 201. A handle 205 is installed on the upper end of the air blowing box 204. The mixing mechanism 300 includes a sleeve shaft 301 rotatably mounted on the outside of the connecting rod 201 and a drug loading cylinder 305 disposed on the connecting rod 201. This utility model is designed specifically for drug processing in the pharmacy department. It is simple and quick to operate, capable of crushing and mixing small amounts of drugs each time, and is small in size for easy carrying and cleaning after use.

[0021] Specifically, a movable hole is provided at the center of the upper end of the threaded cap 102. The connecting rod 201 and the sleeve shaft 301 are located inside the movable hole, and the size of the sleeve shaft 301 is adapted to the size of the movable hole. An air outlet is provided on the threaded cap 102, and a baffle net 103 is provided inside the air outlet. The design of the threaded cap 102 facilitates the opening and closing of the device, making it convenient for users to add medicine and take out the crushed and mixed medicine. The baffle net 103 effectively blocks the medicine powder and prevents it from being discharged from the device with the airflow.

[0022] Furthermore, the connecting rod 201 is hollow, and the exhaust plate 203 has a cavity. Air outlets are arrayed at the lower end of the exhaust plate 203. Both ends of the connecting rod 201 are connected to the exhaust plate 203 and the air blower box 204, respectively. This interconnection between the connecting rod 201, the exhaust plate 203, and the air blower box 204 facilitates the flow of air from the air blower box 204 into the exhaust plate 203.

[0023] It is worth noting that a micro motor 206 is installed inside the blower box 204, and a fan blade 207 is installed at the end of the output shaft of the micro motor 206. Air inlets are arrayed on the outer surface of the blower box 204. When the micro motor 206 is working, it can make the fan blade 207 rotate at high speed. When the fan blade 207 rotates at high speed, external air can enter the blower box 204 through the air inlets, thereby blowing air.

[0024] It is worth mentioning that a fan blade 302 is installed on the sleeve shaft 301, and the fan blade 302 is located above the threaded cover 102. A fixing rod 303 is arranged in an array on the lower outer surface of the sleeve shaft 301, and a stirring rod 304 is installed at the end of the fixing rod 303. The upward airflow can blow the fan blade 302 to rotate the sleeve shaft 301, thereby causing the stirring rod 304 to mix the pulverized medicine.

[0025] It is worth noting that the upper end of the drug-filling cylinder 305 is open, and the drug-filling cylinder 305 is shaped like a trumpet opening outwards from bottom to top. Air inlets are arrayed along the upper edge of the drug-filling cylinder 305, and the stirring rod 304 is located inside the drug-filling cylinder 305. The air inlets on the drug-filling cylinder 305 form a dedicated airflow channel. After the airflow passes through the air inlets, it can be dispersed. Because the drug-filling cylinder 305 is trumpet-shaped with a large upper opening, combined with the intermittent operation of the motor, the pulverized medicine can easily pass along the outer surface of the drug-filling cylinder 305 through the air inlets and enter the drug-filling cylinder 305. With the help of the stirring rod 304, the medicine can be mixed.

[0026] Working Principle: This embodiment provides a pharmaceutical department-specific drug pulverizing and mixing device. In use, the user first opens the threaded cap 102, uses the handle 205 to pull out the loading cylinder 305 from the pulverizing cylinder 101, places several granules of medicine to be pulverized into the pulverizing cylinder 101, then reinstalls the threaded cap 102. The user holds the handle 205 and repeatedly moves the pulverizing pestle 200 up and down, causing the mortar ball 202 to pulverize the medicine in the pulverizing cylinder 101. During this process, the micro motor 206 inside the air blower box 204 is activated, its output shaft drives the fan blades 207 to rotate. Outside air enters through the air inlet on the outer surface of the air blower box 204, flows through the hollow connecting rod 201 into the cavity of the exhaust plate 203, and is blown out from the air outlets arrayed at the lower end of the exhaust plate 203. The blown air can disperse the drug powder. Simultaneously, because the bottom of the pulverizing cylinder 101 is closed, the pulverized medicine... The powder is blown upwards to prevent it from accumulating at the bottom of the pulverizing cylinder 101, making the pulverization more uniform. After the powder is blown upwards by the airflow through the airflow port, most of the powder can fall into the medicine container 305 due to the dispersion of the airflow. Secondly, the powder transported upwards by the airflow is blocked by the blocking net 103, and the air is discharged from the blocking net 103. By intermittently starting the micro motor 206, the powder can fall into the medicine container 305. The blown airflow will impact the fan blade 302 on the sleeve shaft 301 above the threaded cover 102, causing the sleeve shaft 301 to rotate around the connecting rod 201. When the sleeve shaft 301 rotates, it drives the fixed rod 303 and the stirring rod 304 at the end to rotate, stirring and mixing the medicine in the medicine container 305. After pulverization and mixing are completed, the threaded cover 102 is opened and the handle 205 is pulled to pull the medicine container 305 out of the pulverizing cylinder 101, so that the pulverized and mixed medicine can be poured out.

[0027] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
