At present, the types of macromolecule automatic medicine dissolving and adding equipment on the market are few, including a cylinder type, a double cylinder type, a three-groove type and the like, wherein the three-groove type macromolecule automatic medicine dissolving and adding equipment is widely used in various industries. The following defects are found to exist in the actual use process of the macromolecular automatic medicine dissolving and adding equipment:
1. automated formulation of precise concentrations of pharmaceutical agents is difficult to achieve.
Such as: the automatic medicine dosing equipment that dissolves of three-tank formula polymer, preparation solution get into the hold up tank from preparation groove through the ageing groove again, are series connection between the three-tank, and the automatic control scheme that dispenses of this equipment is: when the liquid level of the storage tank is at a high level, the preparation process is automatically stopped, and when the solution drops to a low liquid level, the batching process is automatically started. Firstly, the water supply pressure determines the water inflow in unit time, and the water supply pressure cannot be constant and stable all the time, so that the water inflow in the same time period is unequal, secondly, because the three tanks are connected in series, when the liquid level of the storage tank drops to a low liquid level, the control of the liquid medicine concentration can be influenced by the prepared liquid medicine in the medicine dissolving tank, and therefore, the three-tank type high-polymer automatic medicine dissolving and feeding equipment can hardly prepare the liquid medicine with accurate concentration.
2. The intelligent control level of the automatic control system is not high.
3. For agents with different dissolution time requirements (or for the same agent at different ambient temperatures), precise concentration formulations are difficult to adapt.
Different medicaments have different dissolution time, even if the same medicament needs different dissolution time under different environmental conditions, the requirement of different dissolution time is not met by only depending on the retention time of the medicament in the medicament dissolving tank and the ageing tank.
4. The preparation of medicaments with variable soluble dose requirements is not easy to realize. For example, a user only needs to prepare 1/2 or 1/3 medicine dispensing devices with a certain concentration, and the automatic medicine dissolving and adding devices in the market do not have the automatic preparation function.
