Description

Technical Field

[0001] The invention relates to the technical field of pharmacy, in particular to a child health care pharmacology auxiliary experimental device and a use method thereof. Background Art

[0002] In the field of pediatric health pharmacology research, drug preparation and processing is a crucial part of the experimental process. Traditional drug processing methods often rely on manual operations, which are not only inefficient, but also difficult to ensure the uniformity and consistency of drug particles, which has a great impact on the accuracy of experimental results. Especially when dealing with children's medication, due to the particularity of children's physiological functions, there are more stringent requirements on the size, shape and purity of drug particles.

[0003] Traditional drug crushing and sorting equipment usually has the following problems:

[0004] Low crushing efficiency: Traditional crushing equipment often uses a single crushing method, such as mechanical grinding or impact crushing. This method has low crushing efficiency when processing drugs with high hardness or high viscosity, and is prone to overheating, affecting the properties of the drug.

[0005] Inaccurate sorting: The sorting process usually relies on manual screening or the use of simple sieves for sorting. This method makes it difficult to accurately control the size of drug particles and can easily lead to cross-contamination of drug particles.

[0006] Low degree of automation: The traditional drug processing process requires a lot of manual participation, which is not only labor-intensive, but also easily affected by human factors during the operation, resulting in reduced repeatability and reliability of experimental results.

[0007] Poor equipment adaptability: Different drugs have different physical and chemical properties. Traditional equipment is often difficult to adapt to the processing needs of multiple drugs and requires frequent adjustments and replacements, which increases the cost and time of the experiment.

[0008] Therefore, there is an urgent need for an efficient, automated, and adaptable child health pharmacology auxiliary experimental device to solve the above problems. The device should have the following characteristics: it can efficiently and evenly crush drugs of various properties; it can accurately sort out drugs of different particle sizes; it has a high degree of automation and reduces manual participation; it has strong adaptability and can handle multiple types of drugs; it is easy to clean and maintain to ensure the accuracy and reliability of experimental results.

The number of feed troughs is set to three, and different particle sizes of multiple medicines can be crushed and screened to meet different needs.

[0031] In the second aspect, a method for using a child health pharmacology auxiliary experimental device, the specific steps are as follows:

[0032] Step 1: Preparation stage:

[0033] Check and ensure that all parts are firmly connected and that the motor, transmission box, crushing and sorting mechanism, etc. are in good working condition;

[0034] According to the experimental requirements, the switch states of the first discharge plate, the second discharge plate and the third discharge plate are adjusted to control the outflow of drugs with different particle sizes;

[0054] 1. The device adopts a multi-stage crushing mechanism, which drives the crushing blade to rotate at high speed through a motor, achieving efficient crushing of medicinal materials such as Astragalus, Atractylodes, and Saposhnikovia. Compared with traditional manual or single crushing equipment, the processing efficiency is significantly improved. The device has built-in multi-layer screening mesh plates, which can be flexibly adjusted according to the particle size requirements of the medicinal materials. The screening mesh plates shake under the drive of the connecting rod mechanism, which promotes the uniform screening of the medicinal materials and ensures the precise control of the particle size of the medicinal materials. The entire processing process is driven by a motor and realizes automated operation through a control panel, which reduces manual intervention and improves the accuracy and stability of the processing;

[0055] 2. By adjusting the aperture of the sieving mesh and the operating parameters of the motor, the particle size of the medicinal materials can be accurately controlled to meet the high requirements of pharmacological experiments on the particle size of medicinal materials. After fine grinding, the effective ingredients of medicinal materials such as Astragalus, Atractylodes, and Saposhnikovia are easier to extract and absorb, which improves the accuracy of drug efficacy evaluation. The high-precision processing of the device ensures that the particle size of the medicinal materials is consistent in each experiment, improving the repeatability and reliability of the experiment.

[0093] Place the collection box 5 at the bottom of one side of the frame 1, ensuring that the collection slot corresponds to the discharge plate;

[0094] If multiple drugs need to be processed, different drugs are fed into the three feed slots 11 respectively;

[0095] Step 2: Startup phase:

[0096] Start the motor 3 through the control panel 4 and set the operating parameters, including the speed and working time;

[0097] The motor 3 drives the main shaft 31 to rotate, and then drives the first rotating shaft 21, the second rotating shaft 22 and the third rotating shaft 23 and the crushing blades 214 thereon to rotate through the gear belt to start crushing the medicine;

[0098] Step 3: Crushing and sorting stage:

[0100] The crushed medicine falls onto the screening mesh plate 152 through the feeding chute 1511 for preliminary screening;

[0101] The drug particles that meet the aperture of the screening mesh plate 152 pass through the mesh and fall to the crushing tank 151 or the collection box 5 of the next layer, while those that do not meet the aperture of the screening mesh plate 152 slide through the screening mesh plate 152 and fall to the conveying rack 73;

[0102] The screening mesh plate 152 is driven by the rotating disk 211, the first connecting rod 212 and the second connecting rod 213 to shake, thereby promoting drug screening;

[0103] The drugs that fail to pass the screening are collected by the conveyor frame 73 on the conveyor belt mechanism, and under the action of the extrusion limiter 16, they slide through the receiving plate 17 to the inside of the pulverizing tank 151 for repeated pulverization;

[0111] Examples, such as Figures 1 to 6 As shown:

[0112] Choose the three herbs of Astragalus, Atractylodes and Saposhnikovia:

[0113] Child health care related:

[0114] Astragalus, Atractylodes macrocephala and Saposhnikovia divaricata are all commonly used medicinal materials in pediatrics of traditional Chinese medicine. They have the effects of enhancing immunity, strengthening the spleen and replenishing qi, dispelling wind and relieving exterior symptoms, and are closely related to children's health care.

[0115] By finely processing these three medicinal materials through this patented device, their medicinal effects can be better exerted, providing a basis for the research and development of children's health products.

[0116] Pharmacological experiment requirements:

[0117] Pharmacological experiments require precise control of the particle size and component release of medicinal materials to evaluate their effects on children's health.

[0118] This patented device can achieve fine crushing and sorting of medicinal materials, meeting the high requirements of pharmacological experiments for medicinal material processing.

[0119] Application of auxiliary experimental devices:

[0120] As a children's health pharmacology auxiliary experimental device, its original design intention is to improve the efficiency and accuracy of medicinal material processing and provide strong support for pharmacological experiments.

[0121] Astragalus, Atractylodes macrocephala and Saposhnikovia divaricata were selected as experimental medicinal materials in order to verify the feasibility and effectiveness of the device in practical applications.

[0122] Medicinal material selection and processing objectives

[0123] This example selected three medicinal materials, namely, Radix Astragali, Rhizoma Atractylodis Macrocephalae and Radix Saposhnikoviae, and set the following processing targets according to the characteristics of the medicinal materials and experimental requirements:

[0124] Astragalus: It needs to be ground to above 200 mesh to ensure that its active ingredients such as polysaccharides and saponins can be more easily extracted and absorbed.

[0125] Atractylodes macrocephala: It needs to be ground to about 150 mesh to improve the bioavailability of its active ingredients, while avoiding powder flying and loss caused by excessive grinding.

[0126] Saposhnikovia divaricata: Although the particle size has relatively little effect on the efficacy, in order to maintain the consistency of the formula, it is recommended to grind it to a particle size similar to that of Astragalus membranaceus and Atractylodes macrocephala, that is, about 150 mesh.

[0127] 3. Experimental Procedure

[0128] Preparation stage:

[0129] Astragalus, Atractylodes macrocephala and Saposhnikovia divaricata are respectively fed into the device through three feeding troughs 11.

[0130] The aperture of the screening mesh plate 152 of the crushing and sorting mechanism 15 is adjusted according to the processing target of the medicinal material.

[0131] Startup phase:

[0132] The motor 3 is started through the control panel 4, and the appropriate speed and working time are set.

[0133] The motor 3 drives the main shaft 31 and the transmission mechanism to rotate, thereby driving the crushing blade 214 to start crushing the medicinal materials.

[0134] Crushing and sorting stage:

[0135] The medicinal material is crushed by the crushing blades 214 in the crushing tank 151 .

[0136] The crushed medicinal materials fall onto the screening mesh plate 152 through the feed chute 1511 for preliminary screening.

[0137] The medicinal material particles that meet the aperture of the screening mesh plate 152 pass through the sieve holes and fall into the next layer of the crushing tank 151 or directly enter the collection box 5.

[0138] The medicinal material particles that have not passed the screening are collected by the conveying frame 73 on the conveyor belt mechanism, and under the action of the extrusion limiter 16, they slide through the receiving plate 17 to the inside of the crushing tank 151 for repeated crushing.

[0139] The screening mesh plate 152 is driven by the rotating disk 211, the first connecting rod 212 and the second connecting rod 213 to shake, thereby promoting the screening of medicinal materials.

[0140] Discharging and collecting stage:

[0141] After multi-layer crushing and screening, Astragalus, Atractylodes and Saposhnikovia respectively reached the predetermined particle size requirements.

[0142] Medicinal materials of different particle sizes slide into corresponding collecting slots of the collecting box 5 through the first discharge plate 12 , the second discharge plate 13 and the third discharge plate 14 , respectively.

[0143] Cleaning and maintenance phase:

[0144] After the experiment, the crushing trough 151, the screening mesh plate 152, the sliding trough 153 and the conveyor belt mechanism were thoroughly cleaned.

[0145] The worn parts such as the crushing blade 214 and the conveyor belt 71 were checked and replaced.

[0146] 4. Experimental Results and Discussion

[0147] Through the child health pharmacology auxiliary experimental device of this embodiment, Astragalus, Atractylodes macrocephala and Saposhnikovia divaricata all successfully reached the predetermined particle size requirements.
