Abstract
The utility model discloses a conveniently clamped segmental type stirring device of a dissolution tester. The conveniently clamped segmental type stirring device comprises a revolving bar and a stirring head, wherein the tail end of the revolving bar is connected with the stirring head in a detachable manner; and one end of the revolving bar, far away from the stirring head, is provided with a clamping handle. According to the conveniently clamped segmental type stirring device of the dissolution tester, the revolving bar is in threaded connection with the stirring head in a detachable manner, and when the stirring head needs to be replaced, an another stirring head is installed just by screwing off the stirring head for replacement without moving the position of the revolving bar. According to the design, the revolving bar does not need to be repositioned, so that a large amount of time of a user is saved and the accuracy for the test of dissolution rate is increased; and the revolving bar can be tightly clamped by using the clamping handle and a through hole to achieve high stability and ensure that the revolving bar does not fall off during stirring.
Description
Technical field
The utility model belongs to the pharmaceutical equipment field, particularly relates to the sectional type stirring apparatus of the digestion instrument that makes things convenient for clamping.
Background technology
Dissolution rate (Dissolution rate) also claim dissolution rate, is meant under specified solvent and condition the speed and the degree of medicine stripping from solid pharmaceutical preparations such as tablet, capsule, granule.The process of measuring the solid pharmaceutical preparation dissolution rate is called dissolution rate test (Dissolution test), and it is a kind of disintegration of oral solid formulation in intestines and stomach and in vitro test method of stripping simulated.The drug dissolution inspection is a kind of effective means of estimating preparation quality and technological level; The difference that can reflect crystal formation, granularity, prescription composition, auxiliary material kind and character, the production technology etc. of main ingredient to a certain extent; It also is a kind of effective standard of estimating preparation active component bioavilability and preparation uniformity coefficient; Can effectively distinguish the difference of same kind of drug bioavailability, therefore be one of drug quality control essential items for inspection.
It is generally acknowledged; Slightly solubility (referring generally to slightly soluble or insoluble in water) medicine; Because of the medicine (comprising soluble drug) that preparation prescription and production technology cause unsettled medicine of clinical efficacy and therapeutic dose and dosis toxica to be close, must set the dissolution test item in its oral solid formulation quality standard.In addition, in the prescription screening of solid pharmaceutical preparation and the technological process of production formulation process, also need the dissolution rate of exploitation formulation is done comprehensive investigation.Feasible dissolution rate test method(s) should be all must reach test findings at different time, place to the dissolution determination of same preparation or the mensuration between the different operation person to have good reappearance.
Therefore, the digestion instrument that is used for the dissolution rate test is had very high requirement, all good design should be arranged each small details.
At present, the structure of the stirring apparatus of digestion instrument use is such: the bull stick and the stirring-head that comprise integrated setting.The bull stick of this integrated setting and stirring-head are when changing stirring-head, and package unit must be replaced simultaneously.Be researcher when changing stirring apparatus, must take out a complete set of bull stick and stirring-head, change and install another kind of bull stick and stirring-head.During a complete set of like this replacing, replacing has also taken place in the position of bull stick, therefore, needs position bull stick again after each the replacing, is in the height of indication and is in the center of stripping rotor to guarantee bull stick.This replacing process is very loaded down with trivial details.
The utility model content
The utility model technical matters to be solved provides the sectional type stirring apparatus of the digestion instrument that makes things convenient for clamping, uses this sectional type stirring apparatus, when changing, only need pull down stirring-head, changes another kind of stirring-head is installed; And the position that need not to move bull stick utilizes grip shank that bull stick is clamped.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the sectional type stirring apparatus that makes things convenient for the digestion instrument of clamping; Comprise bull stick and stirring-head; The end of said bull stick is connected through removably with stirring-head, and said bull stick is provided with grip shank away from an end of stirring-head.
Said grip shank is provided with through hole.
Said stirring-head comprise center-pole, with the paddle of center-pole integrated setting, said center-pole is connected through removably with stirring-head.
The quantity of said paddle is two, and two paddles are axis of symmetry with the center-pole, are arranged on the both sides of center-pole.
The end of said bull stick is provided with external thread; Said center-pole is a hollow tubular structure, and the inside of said center-pole is provided with internal thread; The external thread of said bull stick is screwed on the internal thread of center-pole just.
Said bull stick and stirring-head are processed by stainless steel material.
In sum, the utility model compared with prior art has following advantage:
(1), the utility model is provided with simple in structure; Manufacturing cost is lower; Utilize grip shank and the through hole can be with the bull stick clamped; Steadiness is high, can not come off when guaranteeing to stir, and is applicable to the test of scientific research departments such as each big-and-middle universities and colleges, medical treatment, health and epidemic prevention, environmental monitoring, pharmaceutical industry to dissolution rate.
(2), the bull stick and the stirring-head of the utility model link together through the removably that is threaded, and when needs are changed stirring-head, only need screw off stirring-head, change to install another kind of stirring-head and get final product, and need not the position of mobile bull stick.This design need not bull stick is reorientated, and has saved user's plenty of time, has also improved the dissolution rate test accuracy.
