Dispensing device and dispensing unit of granular medicament

Technical Field

The utility model relates to an automatic allotment technical field of graininess medicament specifically is a be applied to traditional chinese medicine prescription granule intelligence allotment equipment, has realized the automatic dispensing device who dispenses of this kind of equipment, the unit that dispenses.

Background

As a representative of standardized Chinese medicines, Chinese medicine formula granules are accepted by more and more doctors, and in recent years, the market thereof is facing the development of well-spraying type. Manual dispensing of traditional Chinese medicine formula granules by an operator according to a prescription is very slow and is prone to errors, so that special intelligent dispensing equipment is needed to realize automation and intellectualization of formula granule dispensing. The intelligent dispensing equipment for the traditional Chinese medicine formula particles realizes real-time data interaction with a hospital HIS system through a control computer, automatically acquires prescription information, and completes a series of operations of intelligent prescription checking, automatic dispensing and packaging, printing and labeling and the like, thereby realizing 'robot changing' of a traditional Chinese pharmacy.

The utility model provides a dispensing device, the unit of dispensing are above-mentioned intelligent allotment equipment and realize the key technology link of automatic dispensation, have decided the precision and the efficiency of allotment at to a great extent. The traditional Chinese medicine formula has more varieties of granules and larger property difference, and meanwhile, part of medicaments are easy to change the properties (such as density, hardness, viscosity, granule fluidity and the like) caused by high-temperature moisture; the change of the characters can greatly influence the quality of blending, so that the precision of dispensing is reduced and even blending cannot be carried out.

The existing blending technology comprises a gravity direct medicine falling mode, a magnetic linear medicine falling mode and a bin body type blending mode. These techniques are susceptible to the change of the properties of the medicament, for example, the direct gravity-based falling medicament method cannot be prepared due to the hardening of the medicament or the preparation precision is extremely poor; the blending precision of the magnetic linear medicine falling mode is easily influenced by the magnetism of the medicine; the existing bin type blending mode repeatedly extrudes granular medicaments when the volume of a bin body is adjusted, and meanwhile, the granular medicaments are heated by friction in the extrusion process, so that the properties of the medicaments are changed, and the medicaments are adhered and hardened, so that the dispensing precision is seriously influenced.

In order to solve the above problems, it is necessary to design a dispensing device that is adaptable to actual situations where the properties of the drug are widely different and easily changed, and that is not affected by the magnetism of the drug; more importantly, the medicine properties can not be changed and the medicine dispensing precision can not be influenced due to repeated pushing and squeezing of the medicine in the medicine dispensing process.

SUMMERY OF THE UTILITY MODEL

Technical problem to be solved

Currently, there are three main technical routes for the formulation of granular drugs: a gravity direct medicine falling mode, a magnetic linear medicine falling mode and a bin body type blending mode.

The gravity direct medicine falling mode has the advantages of simple original structure and difficulty in controlling precision, and particularly when the medicines are hardened and adhered due to high-temperature humidity, the blending precision of the mode is extremely poor, and even blending cannot be performed. The magnetic force straight line medicine falling mode uses a magnet in the adjusting module, is easily influenced by the magnetism of the medicine, and has extremely unsatisfactory allocation precision for certain medicines with larger magnetism. The bin type blending mode is a widely applied blending mode. At present, the blending technology based on the mode can push the medicament when the volume of a bin body is adjusted and the medicament falls, so that the properties of the medicament are changed; meanwhile, heat is generated by friction motion in the pushing process, so that the medicament with changed properties is adhered and hardened. The existence of such a situation seriously affects the dispensing accuracy.

The utility model provides a not enough to prior art, the utility model provides a dispensing device of graininess medicament, the unit that dispenses can satisfy the demand of dispensing of the graininess medicament of different characters, has overcome a great deal of defect that exists among the above-mentioned allotment technique, has realized the accuracy of graininess medicament allotment to a higher degree.

(II) technical scheme

In order to achieve the above purpose, the utility model provides a following technical scheme:

a dispensing device for granular medicaments comprises a shell and a dispensing adjusting mechanism arranged in the shell, wherein the shell consists of an upper shell and a lower shell, the upper shell is provided with a medicament inlet, the lower shell is provided with a medicament outlet, the dispensing adjusting mechanism consists of a medicament adding rotating body, a medicament adding adjusting body and a medicament adding adjusting top block, the medicament adding rotating body is arranged on two sides of the medicament adding rotating body, the medicament adding rotating body consists of a cylindrical main body and a transmission shaft which are horizontally arranged, a rotary bin is arranged on the side surface of the cylindrical main body of the medicament adding rotating body, a guide hole penetrating through two bottom surfaces is arranged inside the cylindrical main body, the medicament adding adjusting body is provided with a volume adjusting block matched with the rotary bin and a top rod matched with the guide hole, the medicament adding adjusting top block is arranged on the top rod of the medicament adding adjusting body, the relative position of the volume adjusting block in the rotary bin is adjusted in a stepless variable, the medicine dispensing adjusting mechanism is characterized in that the material transferring bin is communicated with the medicine inlet and the medicine falling port respectively when rotating, a minimum quantitative volume cavity is arranged at the end part, close to the medicine adding rotating body, of the volume adjusting block of the medicine adding adjusting body, and the minimum quantitative volume cavity is set for minimum volume quantification.

The initial state of the dispensing adjusting mechanism is that the opening of the medicine adding rotating body material transferring bin is downward. When the relative position of the volume adjusting block in the transferring bin is moved, the volume adjusting block is not in contact with the medicament in the medicament storage bottle, so that the medicament property change caused by pushing the medicament can not be caused, the phenomenon that the medicament is bonded and hardened due to heat generated by motion friction is avoided, and the dispensing precision is obviously improved.

In addition, the volume is adjusted by generally adopting a push-pull type linear driving mechanism in the conventional volume adjusting mode, and the notches are easy to wear due to repeated bidirectional stress in the same notch, so that the adjustment precision is influenced due to the fact that gaps are easy to appear after the groove is used for a long time.
