Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical equipment, in particular to a fully automatic opening, closing and locking medicine decocting machine. Background Art
[0002] With the continuous progress of science and technology, traditional manual decoction is gradually replaced by decoction machines. Using Chinese medicine decoction machines to decoct Chinese medicine has the following advantages: First, due to the existence of pressure, the effective ingredients in Chinese medicinal materials are easier to decoct, and the protein in animal medicines is easier to hydrolyze. However, some medicines made of hard minerals and shells are not easy to extract effective ingredients at room temperature and pressure. The extraction rate of effective ingredients can be improved by pressurizing and applying high temperature, solving the problem of "decoction first"; secondly, due to the closed decoction, aromatic drugs can be fully retained, solving the problem of "decoction later". The reduction of water vapor in the closed decoction can also improve the working environment and free the staff from the high temperature and high humidity environment; thirdly, the pressure and temperature during the decoction process fully kill the bacteria and spores. The decoction and packaging process is a fully closed process, which ensures the sterility and hygiene of the medicine solution; fourthly, several doses can be decocted together, and the pharmacy formula can adopt the total measurement method, which not only solves the problem of inaccurate dosage and low efficiency of medicinal pieces, but also ensures that the concentration and composition of each dose of medicine are evenly distributed, and there will be no problems of different tastes and ingredients of the medicine solutions before and after.
[0003] At present, the opening and closing of the pot lid of the medicine decoction machine is generally done manually. Because one person in a production enterprise that uses a medicine decoction machine to decoct medicine needs to manage several or even more than a dozen machines, if the pot lid is opened and closed manually, it is calculated as eight hours a day, and each single medicine decoction machine needs to be opened and closed once per hour. If it is calculated as taking care of 10 machines, one person will open and close the pot lid of the medicine decoction machine 160 times a day, which has the problems of long time for opening and closing the lid, low labor efficiency, and high labor intensity of operators. Therefore, various automatic lid-opening medicine decoction machines came into being. For example, the fully automatic closed medicine decoction machine with patent number ZL20222211025322 applied by Hubei Yongbang Engineering Technology Co., Ltd. on May 10, 2022 uses a cylinder to automatically control the pot lid and the extrusion plate, which improves the labor intensity of the operator, improves the efficiency of decoction, and saves labor. Another example is a medicine decoction machine with patent number ZL20222213110457 applied by Beijing Donghuayuan Medical Equipment Co., Ltd. on June 1, 2022. It uses the lever principle to brake and open the lid, eliminating the need for operators to manually open and close the lid, which can also reduce labor intensity and improve decoction efficiency. Although the existing various automatic opening and closing medicine decoction machines have solved some practical problems such as the labor intensity of workers, they generally have problems such as rough structure, low precision, and easy deformation and leakage.
