Abstract
The utility model relates to a cylindrical constant temperature water bath box used for a medicine leaching tester. The utility model is characterized in that the utility model consists of a box body, an electric heater, a temperature sensor and a rotatable agitator. The utility model has the advantages that firstly, the external conditions of a leaching glass are same and also has an agitator, therefore the temperature variance of the leached medium in the leaching glass is little; secondly, seven holes are uniformly distributed on the surface of the box body, and can be used to hold seven leaching glasses at the same time, thus the requirement of the pharmacopoeia that six test articles are tested in six leaching glasses at one time is met; thirdly, when the water quantity in the water bath box is same and the depth of the water in the water bath box is same, compared to a rectangular water bath box, the cylindrical water bath box has smaller surface area, namely the heat eliminating area is small, therefore, the temperature fluctuation of the water in the water bath box is less; fourthly, the electric heater is arranged inside the box body, being convenient for regulating the temperature inside the box body, and uneasy to be influenced by the outside temperature; fifthly, the temperature inside the water bath box can be equalized by applying the agitator, to achieve less ambient temperature variance of each leaching glass.
Description
(1) technical field:
The utility model relates to a kind of drug inspection device, the cylindrical constant water bath box of especially a kind of medicine dissolution test instrument.
(2) background technology:
In the process of doing the medicine dissolution test, stipulate that by pharmacopeia the dissolution medium temperature constant is at 37 ℃ ± 0.5 ℃ in each stripping rotor, existing for this reason medicine dissolution test instrument all is equipped with the constant water bath box of the cuboid of a hollow, each stripping rotor is placed water bath, and constant water bath box has the electric heater of a band temperature controller outward, and has a water pump to link to each other with water bath by water pipe, and electric heater is subjected to the control of temperature controller, water pump is worked always, makes the water in the water bath be in recurrent state.
At present, cuboid water bath shortcoming has two: thereby 1. because each stripping rotor external condition of living in water bath temperature contrast of dissolution medium in each stripping rotor that causes inequality is bigger; 2. the water yield is identical in water bath, and when the degree of depth of water in the water bath was identical, the cuboid water bath was bigger than cylindrical water bath surface area, and promptly area of dissipation is big, can be unfavorable to water bath constant temperature.
(3) utility model content:
The purpose of this utility model is to provide a kind of medicine dissolution test instrument cylindrical constant water bath box, it can overcome the deficiencies in the prior art, is the constant water bath box of a kind of cylindrical water bath to guarantee that the dissolution medium temperature contrast is little, area of dissipation is little, fluctuating temperature is little.
The technical solution of the utility model: the cylindrical constant water bath box of a kind of medicine dissolution test instrument is characterized in that it is made up of casing, electric heater, temperature sensor and rotatable stirrer; Said casing is a hollow cylindrical, and its upper surface has the putting hole of stripping rotor and the putting hole of temperature sensor, and the electric heater by temperature controller control is equipped with in its inside, and rotatable stirrer places the bottom in the casing.
Electric heater on the above-mentioned said cylindrical constant water bath box, its temperature controller or place cylindrical constant water bath box body or place cylindrical constant water bath box outside.
The putting hole of the stripping rotor that above-mentioned said casing upper surface has can be placed the hole of the 8th stripping rotor in addition for evenly to be distributed as seven along circumference at the center.
Above-mentioned said electric heater is circular electric heater.
Above-mentioned said rotatable stirrer adopts the magnetically-actuated stirrer.
Principle of work of the present utility model: by temperature sensor the bath temperature information in the water bath is passed to temperature controller, thereby control heater makes the temperature inside the box reach requirement; Simultaneously stirrer stirs water in the water bath in the casing, makes in the case temperature everywhere even.
Superiority of the present utility model is: 1. the external condition of stripping rotor is identical a stirrer again, so the dissolution medium temperature contrast is less in each stripping rotor; 2. in tank surface 7-8 the hole that evenly distribute, place 7-8 stripping rotor simultaneously, can satisfy the requirement of once in 6 stripping rotors, measuring 6 parts of test samples of pharmacopeia regulation; 3. the water yield is identical in water bath, and when the degree of depth of water was identical in the water bath, with respect to the cuboid water bath, the surface area of cylindrical water bath was little, and promptly area of dissipation is little, thereby the fluctuation of water temperature is less in the constant water bath box; 4. electric heater is installed in the casing, is easy to regulate temperature in the casing, and is not subject to extraneous thermal effect; 5. use stirrer can make the interior temperature of water bath even, thereby it is littler to reach the residing environment temperature difference of each stripping rotor.
(4) Figure of description:
Fig. 1 is the vertical view of the related a kind of medicine dissolution test instrument of the utility model with cylindrical constant water bath box;
Fig. 2 is the cut-open view of Fig. 1;
Wherein, 1 is casing, and 2 is electric heater, and 3 is temperature sensor, 4 rotatable stirrers, and 5 is the putting hole of stripping rotor, 6 is the putting hole of temperature sensor.
(5) embodiment:
Embodiment: a kind of medicine dissolution test instrument is with cylindrical constant water bath box (seeing Fig. 1,2), it is characterized in that it is made up of casing 1, electric heater 2, temperature sensor 3 and rotatable stirrer 4; Said casing 1 is a hollow cylindrical, and its upper surface has the putting hole 5 of stripping rotor and the putting hole 6 of temperature sensor, and the electric heater 2 by temperature controller control is equipped with in its inside, and rotatable stirrer 4 places the bottom in the casing 1.
The putting hole 5 of the stripping rotor that above-mentioned said casing upper surface has evenly is distributed as seven along circumference, can place the hole (see figure 1) of the 8th stripping rotor in addition at the center.
Above-mentioned said electric heater is circular electric heater (see figure 1).
Above-mentioned said rotatable stirrer adopts conventional magnetically-actuated stirrer.
