Eye drop diluting tank

Abstract

The invention discloses an eye drop diluting tank, which comprises a tank body. A stirring mechanism and a diluent pumping mechanism are assembled on the tank body; the diluent pumping mechanism comprises an annular material pipe communicated with the top of the tank body, the bottom of the diluent pumping mechanism is communicated with a plurality of annularly distributed liquid passing pipes, and the lengths of the liquid passing pipes are different. The bottom of each liquid passing pipe is communicated with a liquid spraying disc, and a plurality of liquid discharging holes are formed in the side wall of each liquid passing pipe. The top of the annular material pipe is communicated with a material pumping pipeline. The stirring mechanism comprises a stirring motor, the stirring motor is fixedly connected with a stirring shaft, the bottom of the stirring shaft is fixedly connected with a plurality of stirring pieces, each stirring piece comprises a zigzag stirring rod, and each zigzag stirring rod comprises a first end flat part, a bent part integrally formed with the first end flat part and a second end flat part integrally formed with the bent part; and a plurality of dissolution assisting pieces are fixedly connected to the stirring rod and break the envelope. Through the technical scheme mentioned above, the technical defect that in the eye drop diluting process, the local concentration of liquid medicine is too large is overcome, and the eye drop dissolving and dispersing effects are improved.

Description

technical field [0001] The invention relates to the field of eye drop processing devices, in particular to a dilute eye drop preparation tank. Background technique [0002] Eye drops are a relatively routinely used eye medicine, mostly liquid preparations. During the processing of eye drops, it is often necessary to mix the medicinal solution for preparing eye drops to prepare a high-concentration medicament, and then dilute the high-concentration medicament into a certain concentration of low-concentration medicament. [0003] In the process of medicament dilution, a dilution tank is often used, and the high-concentration medicament is pumped into the dilution tank, and the solvent in the dilution tank is used for dilution. [0004] However, the methods disclosed in the prior art for pumping high-concentration medicaments into the dilution tank mostly use a single pumping pipeline. In the process of pumping medicine, the local concentration is always too high, but in the ...

AI Technical Summary

Problems solved by technology

[0004] However, the methods disclosed in the prior art for pumping high-concentration medicaments into the dilution tank mostly use a single pumping pipeline. In the process of pumping medicine, the local concentration is always too high, but in the actual application, it is found that in the dilution process, the high-concentration medicine is easy to form inclusions due to the local concentration is too large, that is, the high concentration of the local concentration is too large during the dilution process. The medicine is easy to wrap other excipients in the dilution tank, causing sediment at the bottom of the dilution after stirring and diluting. The content test found that the reagent concentration of the medicine is lower than the theoretical value
