Description

Automatic dispensing system for traditional Chinese medicine prescription

Technical Field

The utility model relates to a traditional chinese medicine prescription dispensing system, concretely relates to automatic dispensing system of traditional chinese medicine prescription.

Background

In the field of traditional Chinese medicine, because the varieties and specifications of traditional Chinese medicinal materials, traditional Chinese medicine decoction pieces or traditional Chinese medicines are various (up to thousands), each traditional Chinese medicinal material, traditional Chinese medicine decoction piece or traditional Chinese medicine needs to be stored in a single storage space, and thousands of dense hemp medicine boxes are arranged in the pharmacy regularly around the traditional Chinese pharmacy. When a worker dispenses a traditional Chinese medicine prescription, the content of the prescription and the positions of medicine boxes of various traditional Chinese medicines in the pharmacy are required to be recorded, the medicine boxes are taken to a dispensing table for matching, taking and weighing according to a certain sequence after each traditional Chinese medicine or traditional Chinese medicine decoction piece or single Chinese patent medicine variety in the prescription is identified and contrasted from different positions in the pharmacy, the medicine boxes are required to be put back to the medicine boxes when the medicine boxes are taken and the excessive medicines are taken, the medicine boxes are replenished again when the medicine boxes are not taken, the medicine boxes are put back to the original positions after the replenishment is finished, and the operation is repeated until the dispensing of each medicine in the prescription is finished (up to dozens of times, the dispensing work of a single traditional Chinese medicine prescription can be finished).

In recent years, with the rapid development of the traditional Chinese medicine industry and the vigorous development of the state, the traditional Chinese medicine modernization is realized. The traditional Chinese medicine industry faces huge development opportunities, is limited by traditional processing modes and low efficiency of manual operation, and cannot meet the requirements of people; especially, the current traditional Chinese medicine pharmacy still stays in the current situation hundreds of years ago.

At present, the traditional pharmacy has the following problems:

(1) the dust amount of the working environment is large, the labor intensity of a dispensing worker is high, the person walks more than 4 thousands of steps every day (namely walks more than 30 kilometers), so the mobility of the personnel is extremely high, the separating rate of dispensing personnel of individual institutions reaches more than 200%, and meanwhile, the service quality is caused to be a problem due to high separating rate;

(2) at present, most traditional Chinese medicine rooms carry out 'remuneration according to the prescription', so dispensing personnel pursue speed and prescription preparation measurement is not strictly controlled; high dispensing error rate, high patient complaint rate, etc., leaving numerous clinical safety concerns in the dispensing phase.

(3) Traditional Chinese medicine warehouses cannot count warehouses in real time, manual warehouse inventory checking is needed, warehouse management is disordered, and inventory loss is large; the quality of the medicinal materials is difficult to control, and the 'remuneration according to the prescription' is realized at the same time, so that the staff can be more matched in weight, the pharmacy loss is large, the enterprise cost is greatly increased, and meanwhile, the medicine is added to the society, so that the waste of the medicinal material resources is caused;

(4) the traditional Chinese medicine dispensing mode has low efficiency and high requirement on professional quality of personnel, and meanwhile, due to the factors of high working labor intensity, severe environment, unfixed daily working time and the like, most young Chinese medicine talents do not wish to engage in dispensing of Chinese medicine prescriptions, and the situation that no person is in succession is likely to occur.

(5) Because the varieties of the traditional Chinese medicine decoction pieces are thousands of, except the large amount, different varieties exist at the same time, the traditional Chinese medicine decoction pieces are very similar in appearance, and very professional knowledge is needed to distinguish the varieties, the post is not applicable to common people. And thus more than half a year to cultivate a skilled dispensing person, the enterprise or medical institution needs to invest a lot of cost for training new staff.

(6) In the process of taking and dispensing medicines, the medicines are manually identified again and weighed for multiple times, and after the preparation is finished, the problems that the variety is accurately rechecked and the weight is not rechecked cannot be solved.

Based on the defects, the characteristics of various types and specifications of medicinal materials are combined, the current common moving mode is to move through a conveyer belt, the common main medicinal materials are generally placed on a shelf which is closer to an operation table, some auxiliary medicinal materials are placed at vacant positions which are farther from the operation table, when zero-time calling is needed, if a medicine box shelf is closer to a medicine grabbing person, the quick supply and return of the medicine box can be realized by directly connecting the shelf and the operation table through the conveyer belt which can rotate forwards and backwards, generally, one operation table can effectively and quickly supply and switch the medicinal materials only by being provided with 3-4 conveyer belts, so that the situation that the medicine box is not supplied and sent timely is avoided, when the medicine box shelf is a certain distance away from the operation table, if the conveyer belts which move bidirectionally are adopted, the quantity of the conveyer belts seriously influences the conveying efficiency of the medicine box when the medicine box is small, the quantity of conveyer belt has been many and can not be placed down again, and when a plurality of operation panel were when side by side, the conveyer belt through a just reversing can't carry out the supply of drug effect to the medicinal material at all, consequently, then need carry out the round trip movement that just can effectual assurance medical kit to the feed conveyer belt that has snatched the completion again to the medical kit and carry the feed back conveyer belt cooperation before corresponding goods shelves, two conveyer belts are for reducing occupation space, the upper and lower layer setting of general all adoption, and the operation panel that operating personnel grabbed the medicine is no matter how close to the conveyer belt, because feed conveyer belt and feed back conveyer belt are in the in-process that lasts the pivoted always, if can not be timely take out required medical kit from the conveyer belt, then the first condition of medical kit supply position takes place very easily.

Meanwhile, although the problems of automatic supply and storage of medicinal materials are solved by the existing goods shelves and conveying belts, in the actual prescription dispensing process, the requirements on the quality of operators are high, the personnel cost is high, the labor intensity is high, the working intensity is high, the loss is large, the efficiency is low, the traceability is poor, the supervision is difficult, the inventory difficulty is high, the error probability is high, the working environment is dusty, the environment is severe, the situations of cross infection, dust pollution and the like exist, the mobility of the operators is large, the service quality is difficult to guarantee, and the dispensing cost is high and the period is long.

The above is the current situation of the traditional Chinese medicine pharmacy, so that the intellectualization of the traditional Chinese medicine pharmacy is inevitable in social development. Because the traditional Chinese medicine pharmacy is not changed greatly for thousands of years, huge innovation space and development opportunity are brought to relevant working enterprises, and meanwhile, the process of modernization of the traditional Chinese medicine is also directly promoted.
