Description
Technical field
The present invention relates to and belongs to drug test instrument, is specifically related to a kind of device be automatically prepared solvent.
Technical background
China's States Pharmacopoeia specifications need carry out the Dissolution Rate Testing of medicine to multiple medicine, medicine, in Dissolution Rate Testing, needs tablet, capsule or granule etc. to throw in dissolution medium, then measures speed and the degree of active medicine stripping.Up to the present, the dissolution medium that this detection uses or be called solvent, always by testing crew human configuration, and by being manually placed in stripping rotor.The dedicated water used to dissolution medium can carry out automatic business processing at present, but the configuration of dissolution medium and distribution still adopt manual operation.The problem that this measure brings is: the degree of accuracy and security can not ensure, and labour intensity is large, and proposition of the present invention can make this problem obtain gratifying solution.
Summary of the invention
The object of this invention is to provide a kind of solvent preparation facilities of drug test, it can realize automatic business processing to the mixed configuration of dissolution medium, degassed, preheating and distribution.
Referring to accompanying drawing, technical scheme of the present invention and structural principle are described.Medicine inspection solvent preparing instrument has: apparatus frame, magnetic stirring apparatus, instant electric water heater, membrane pump, degassing membrane component, flowmeter, magnetic valve, agitator, photoelectric liquid-level switch, display screen, vacuum table, control valve and negative pressure pump etc.Its system composition is: the base plate of apparatus frame is fixed with front vertical plate, back vertical plate, magnetic stirring apparatus and instant electric water heater, and the first membrane pump and degassing membrane component are fixed with front vertical plate respectively; First magnetic valve, the second membrane pump, flowmeter and the second magnetic valve are fixed on back vertical plate.The delivery port of the first membrane pump and the water inlet of degassing membrane component are connected to instant electric water heater, are connected to the first magnetic valve between the delivery port of degassing membrane component and the feed tube of agitator.Be connected with the second membrane pump and flowmeter between the drain pipe of agitator and the second magnetic valve, magnetic stirring apparatus is fixed in the below of agitator.Feed tube, drain pipe and photoelectric liquid-level switch are contained in agitator and cover, and the bleeding point on degassing membrane component top is connected to control valve and vacuum table, and control valve is connected with negative pressure pump by the interface on apparatus frame with vacuum table.The solvent configured sucks the second membrane pump by drain pipe, flows through flowmeter and the second magnetic valve is got in stripping rotor by liquid outlet.
Agitator feed tube is by the first membrane pump of connecting successively, instant electric water heater, degassing membrane component, the first magnetic valve, and vacuum table, control valve and the negative pressure pump to be connected with degassing membrane component bleeding point, distilled water or deionized water are carried out heat, degassed, reach the requirement of configuration solvent test water, second membrane pump, flowmeter, second magnetic valve of agitator drain pipe by connecting successively, reach the degree of accuracy that dissolution medium distributes.Agitator covers and is provided with dispensing mouth, can render in agitator by solutes such as acid & alkali liquids, coordinates the configuration realizing dissolution medium with magnetic stirring apparatus.
The beneficial effect of feature of the present invention and generation is: the overall process that automatically can complete dissolution medium mixing, degassed, preheating rapidly, can the solvent direct quantitative prepared be dispensed in stripping rotor, reduce artificial dosing, distribute cause waste time and energy, the drawback that the degree of accuracy is low, lower the danger of dosing, increase work efficiency.For the department such as pharmaceutical factory, medicine inspecting institute provides ideal servicing unit.
Accompanying drawing explanation
Shown accompanying drawing is present system composition and apparatus structure fundamental diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, also by specific embodiment, the present invention is described further: medicine inspection solvent preparing instrument, the concrete structure of its device is: the base plate 2 of apparatus frame 1 is fixed with front vertical plate 3, back vertical plate 4, magnetic stirring apparatus 5 and instant electric water heater 6, first membrane pump 7-1 and degassing membrane component 8 are fixed with front vertical plate respectively, and the first magnetic valve 9-1, the second membrane pump 7-2, flowmeter 10 and the second magnetic valve 9-2 are fixed on back vertical plate.The delivery port of the first membrane pump and the water inlet of degassing membrane component are connected to instant electric water heater, be connected to the first magnetic valve between the delivery port of degassing membrane component and the feed tube 12 of agitator 11, between the drain pipe 13 of agitator and the second magnetic valve, be connected with the second membrane pump and flowmeter.Magnetic stirring apparatus is fixed in the below of agitator, and feed tube, drain pipe and photoelectric liquid-level switch 14 is contained in agitator and covers.The bleeding point on degassing membrane component top is connected to control valve 15 and vacuum table 16, and control valve is connected with negative pressure pump by the interface 17 on apparatus frame with vacuum table.The solvent configured sucks the second membrane pump by drain pipe, flows through flowmeter and the second magnetic valve is got in stripping rotor by liquid outlet 18.
Agitator is covered with dispensing mouth 19; The front panel of apparatus frame is provided with control valve, vacuum table and display screen 20.Not degassed distilled water or deionized water suck described first membrane pump by inlet 21.The position of the second membrane pump and flowmeter can exchange connection.
The invention process process: negative pressure pump work after instrument energising, is vacuumized in degassing membrane component 8 cavity by interface 17, reach the vacuum of setting.First membrane pump starts running, not degassed distilled water or deionized water suck the first membrane pump by inlet 21, flow through instant electric water heater immediately to heat, flow through degassing membrane component immediately degassed, the distilled water of heat de-airing or deionized water are entered in agitator by the first magnetic valve, feed tube.When liquid level touches photoelectric liquid-level switch, photoelectric liquid-level switch provides signal, the first closed electromagnetic valve, and the first membrane pump and negative pressure pump also quit work.Now magnetic stirring apparatus is started working, and will heat and degassed water and (dropping into from mouth of offer medicine) solute carry out mixed preparing solvent, magnetic stirring apparatus stopping after stirring.Start the second membrane pump, the solvent prepared sucks the second membrane pump by drain pipe 13, flows through flowmeter and the second magnetic valve, is got in stripping rotor by liquid outlet 18 according to the numerical value of setting.
