Problems solved by technology

However, through the follow-up and review of the weighing data in the pharmacy, it is found that there are certain problems in this method: the accuracy of dispensing is related to the uniformity of the shape of the drug, and the worse the shape uniformity, the worse the accuracy; Increase, the worse the accuracy of distribution, the greater the fluctuation of weighing
[0006] (2) Low efficiency and slow weighing: According to the information feedback from the pharmacy, since the number of clinical prescriptions is generally large (10-20 flavors), it is calculated by weighing 6 payments per prescription, and the hourly adjustment of a skilled dispenser The amount is about 5-7 payments; for hospitals or clinics with a large outpatient volume, patients often have to wait for several hours to get the medicine
The gravimetric method is accurate in dosage, but the operation is cumbersome and the efficiency is low; the volumetric method is fast and high in efficiency; application

Embodiment 1

[0043] Example 1: Determining the bulk density of traditional Chinese medicines with different natural attributes to determine the main specifications of the traditional Chinese medicine weighing device

[0044] Each medicine has a certain bulk density, or it is formed naturally, such as the granular form of cassia seed, the filamentous form of Phellodendron cork, or processed, such as the powder form of Qingdai, and the small segment form of cassia twig. The bulk density is different from the bulk density or true density in the usual sense. It is a relatively fixed value naturally formed between the drug and the surrounding air in a specific shape state, including the volume voids inside and around the drug. The measurement method is "to a certain Gently add a drug with a certain mass m into a graduated cylinder until the volume V is reached. The formula for calculating the bulk density ρ of the drug is:

[0045] ρ = m v ...

Embodiment 2

[0053] Embodiment 2: Determining the scale size of the traditional Chinese medicine weighing device by measuring the bulk density of traditional Chinese medicine medicines with the same natural attributes

[0054] Three kinds of root and rhizome medicines were selected, namely Salvia miltiorrhiza, Radix Glycyrrhizae, and Poria cocos, and the scales of the traditional Chinese medicine weighing devices for weighing the three kinds of medicines were determined. The bulk densities of salvia miltiorrhiza, licorice, and poria were 0.44, 0.47, and 0.51 g·cm, respectively -3 , the maximum clinical dose is often used 30g, select for 0.5g·cm -3 The traditional Chinese medicine weighing device (the outer diameter of the top surface of the inner container is 3.91cm, height 5cm).

[0055] Precisely weigh 5, 10, 15, 20, 25, and 30 g of Danshen medicinal materials with an electronic balance, gently pour them into the traditional Chinese medicine weighing device, and record the corresponding...

Embodiment 3

[0066] Embodiment 3: the comparison of weighing device of the present invention and drug weight accuracy and weighing time

[0067] Select three low-, medium-, and high-density drugs, i.e. imperina root, salvia miltiorrhiza, and floating wheat, and manufacture corresponding weighing devices based on the data in Table 4 for weighing experiments; randomly select two Chinese medicine dispensers with similar working skills from the Chinese pharmacy ; 1 person adopts the traditional medicine weighing method, and the method is to distribute by visual inspection method after taking the overpaid medicine total amount; Another person adopts the weighing device provided by the present invention to weigh; Both of them adjust according to 6 medicines; Record the adjustment time of the two people, and use the calibrated electronic scale to review the weighing results, and compare the work efficiency and accuracy of the two people. The experimental results are shown in Tables 5, 6, and 7. ...

Abstract

The invention relates to a traditional Chinese medicine decoction piece weighing device. The traditional Chinese medicine decoction piece weighing device comprises a case (1), an internal container (3) and a regulating device, wherein the case (1) is hollow and is provided with a handle (2), the case (1) is provided with an upper edge, a lower edge and an outer side surface, scales are arranged on the outer side surface, the internal container (3) is provided with a top surface, the regulating device consists of at least two slide rails (4) and a sliding device (6), the at least two slide rails (4) are arranged on the case (1), the sliding device (6) is fixedly arranged in the slide rails through a fastening device (5) and moves along the slide rails, the inner diameter of the case (1) is a little greater than the outer diameter of the internal container (3), and the case (1) detachably sleeves the internal container (3) through the regulating device, so that the top surface of the internal container (3) becomes the bottom surface of the traditional Chinese medicine weighing device for containing traditional Chinese medicine. The traditional Chinese medicine weighing device overcomes the defects that the volume of a traditional doser is fixed, and the weighing of different dosages cannot be met. The clinic agent preparation speed is greatly improved, and the work load of agent preparing personnel is reduced.

Description

technical field [0001] The invention relates to a traditional Chinese medicine weighing device with adjustable volume. Background technique [0002] Traditional Chinese medicine dispensing work is an important part of clinical medical work, which closely revolves around the needs of clinical treatment and directly serves patients. The quality of dispensing not only affects the clinical efficacy of the medicine, but also affects the health of patients, and even involves the safety of life. Traditional Chinese medicine dispensing involves a large number of medicines, strong technical expertise, high labor intensity, high degree of individualization of prescriptions, and cumbersome weighing tasks. [0003] Dosage has always been a mystery of traditional Chinese medicine. The accuracy of dosage is directly related to the quality of clinical efficacy. It is especially critical for toxic drugs and drugs with severe effects. Children and the elderly and infirm also need to pay att...
