Abstract
The utility model discloses a conveniently held sampling tube of a dissolution tester. The conveniently held sampling tube comprises a tube body and a filter head, wherein the filter head is installed on the tail end of the tube body and a handle is arranged on the tube body. As the filter head is installed on the tail end of the sampling tube body, the phenomenon of a lower result which possibly exists is avoided; and because medicine particles entering into a pipeline system of the dissolution tester are also one of dissolved systems, and when the medicine particles are separated from the dissolved systems and enter into the pipeline system, the whole dissolution rate is inevitably decreased to a certain extent, and therefore the conveniently held sampling tube is conveniently held by an operator.
Description
Technical field
The utility model belongs to the pharmaceutical equipment field, particularly relates to the stopple coupon of conveniently holding the digestion instrument of taking.
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 stopple coupon structure that digestion instrument uses is such: as depicted in figs. 1 and 2, at the center section of the body 1 of stopple coupon filtering layer or other filtering materials 3 are set.This stopple coupon is when sampling and testing, and the drug particles in the stripping rotor 4 is easy to get into pipe system.Medicine in stripping rotor gets into pipe system, possibly cause drug particles blocking pipeline system on the one hand, and it is on the low side that the opposing party's recto possibly made the result.Because getting into the drug particles of digestion instrument pipe system also is one of system of stripping, after having broken away from digestion series entering pipe system, reduction to a certain degree must appear in whole dissolution rate.
The utility model content
The utility model technical matters to be solved provides the stopple coupon of conveniently holding the digestion instrument of taking, uses this stopple coupon, can avoid drug particles to remain in the stopple coupon and causes the pipe system of digestion instrument to be stopped up.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: conveniently hold the stopple coupon of the digestion instrument of taking, comprise body and filter, said filter is installed in the end of body, and said body is provided with handle.
Said taper knob is combined on the outer wall of body.
Conveniently hold the stopple coupon of the digestion instrument of taking, comprise body and filter, said filter is installed in the end of body.
In the technique scheme, filter is installed in the end of body, all liquid that get into the stopple coupon bodys must filter through terminal filters earlier, can avoid drug particles to get into the body of stopple coupon and cause the pipe system of digestion instrument to be stopped up.
Further, said filter is a tygon column filter.
Further, the filter opening aperture of said filter is 10 microns.
Further, said body is a stainless steel material.
In sum, the utility model compared with prior art has following advantage:
(1), the utility model is provided with simple in structurely, manufacturing cost is lower; Be applicable to of 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 utility model is installed in the end of stopple coupon body with filter, avoided result's phenomenon on the low side that possibly exist.Because getting into the drug particles of digestion instrument pipe system also is one of system of stripping, after having broken away from digestion series entering pipe system, reduction to a certain degree must appear in whole dissolution rate.

Fig. 3 is the structural representation of the utility model embodiment 1.
Fig. 4 is the user mode synoptic diagram of the utility model embodiment 1 stopple coupon.
The corresponding name of each parts is called among the figure: 1-body, 2-filter, 3-filtering layer or other filtering materials, 4-stripping rotor, 5-handle.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is done further to specify, but the embodiment of the utility model is not limited thereto.
Embodiment 1:
Like Fig. 3 and shown in Figure 4, conveniently hold the stopple coupon of the digestion instrument of taking, comprise body 1 and filter 2, said filter 1 is installed in the end of body 1, and said body 1 is provided with handle 5.
Said handle 5 is linked on the outer wall of body 1.In the process of using, operating personnel get with hand-held handle 5, are convenient to the control to body 1, have reduced possibility of accident occurrence, have avoided simultaneously directly contacting body 1 with hand, prevent the temperature of the human body palm of the hand is impacted test result.
Said filter is a tygon column filter.
The filter opening aperture of said filter is 10 microns.
Said body is a stainless steel material.
The utility model is when sampling, and sample has just passed through the filter filtration earlier at the front end of sample introduction in the stripping rotor 4, and this filter type has avoided drug particles to get into body blocking pipeline system on the one hand, and the opposing party's recto has been avoided making result's phenomenon on the low side.
As stated, just can realize the utility model preferably.
Claims (5)
