Abstract
The present invention discloses a solid scintillation vial. The solid scintillation vial comprises a vial cover and a shell, and also comprises a pipe connecting member, an indication sheet, scintillation sheets, absorption sheets and a filter sheet. A gas outlet is arranged at the bottom of the shell, the vial cover is arranged at the top of the shell, a gas inlet is arranged in the middle of the vial cover, and the pipe connecting member extends out of the vial via the gas inlet. The solid scintillation vial is equipped with the pipe connecting member, the indication sheet, the scintillation sheets, the absorption sheets and the filter sheet from top to bottom, wherein there are existed a plurality of scintillation sheets and absorption sheets, and a positioning rod is arranged in the center of the solid scintillation vial, and positions the pipe connecting member, the indication sheet, the scintillation sheets, the absorption sheets and the filter sheet. After acquiring an expiration sample, the solid scintillation vial of the present invention is placed in a scintillation counter for scintillation measurement, thereby avoiding the disadvantages in the prior art of sucking back, polluting environment, and being easy to splash and troublesome to operate, at the same time, possessing a very high measurement reliability.
Description
Technical field
The present invention relates to field of medical device, especially a kind of
14c-carbon dioxide (
14cO
2) the solid scintillator bottle of gas sampling.
Background technology
Breath test has been widely used in the diagnosis of some disease of medical domain, takes specifically when giving experimenter
14after C tagged compound, the reason due to disease can cause the change of metabolic pathway, and one of its change is via the metabolic product of discharging of exhaling
14c-carbon dioxide (
14cO
2) amount to there are differences, gather the carbon dioxide in exhaling, measure wherein
14the radioactivity of C, whether diagnosable disease exists and degree.Such as, the patient being subject to helicobacter pylori infections is oral
14during C-urea, one of the feature due to helicobacter pylori is that it to produce in human body non-existent urease originally, and urease can be by
14c-urea decomposition and producing
14cO
2,
14cO
2excrete from expiration, gather the CO that patient breathes out
2gas is also measured wherein
14cO
2content (
14the radiation activity of C), will far away higher than non-infection population, this is because it is oral not infect helicobacter pylori person
14after C-urea,
14c-urea will be discharged from urine with prototype, instead of discharge from expiration after being decomposed
14cO
2.
For
14c marks collection and the measurement of breath test sample, and one of prior art is CO alkali compounds being dissolved in methanol solution and being formed
2absorbing agent is placed in scintillation vial, the gas that experimenter breathes out passes into absorbent solution through the tubule that is inserted solution, scintillation solution is added again in the absorbing agent absorbing carbon dioxide sample, then the radioactivity of sample is measured by liquid scintillation counter, when measuring, there is higher detection efficiency, but the organic solutions such as poisonous methyl alcohol, toluene must be used, when the shortcoming of existence is such as sampled easily by absorbent solution suck-back entrance, easily splash, contaminated environment, troublesome poeration etc.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of solid scintillator bottle, after gathering specimen of breath, insert scintillation counter to carry out flicker and measure, avoid suck-back that prior art exists, easily splash, the shortcoming of contaminated environment, troublesome poeration, there is again very high measurement confidence level simultaneously.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is:
Solid scintillator bottle, comprise bottle cap and shell, also comprise jointed tubular workpieces, indicating piece, scintiphoto, absorbing sheet and filter, outer casing bottom is provided with gas vent, bottle cap is arranged on cover top portion, gas outlet is had in the middle of bottle cap, jointed tubular workpieces stretches out outside bottle by gas outlet, solid scintillator bottle arranges jointed tubular workpieces, indicating piece, scintiphoto, absorbing sheet and filter from top to bottom, wherein, absorbing sheet and scintiphoto have multiple, and solid scintillator bottle center is provided with backstay, backstay location jointed tubular workpieces, indicating piece, scintiphoto, absorbing sheet and filter.
Further, described absorbing sheet and scintiphoto are alternately distributed, scintiphoto a slice more than absorbing sheet.
Further, described bottle cap is be connected with outer casing screw, and described bottle cap is toward bottle sunken inside.。
Further, described jointed tubular workpieces and backstay intermediate throughholes, jointed tubular workpieces lower end is provided with the groove with backstay head fits.
Preferably, described scintiphoto is the shaped component of plastic scintillant.
Preferably, described absorbing sheet is plastic shaping component.
Preferably, described jointed tubular workpieces, indicating piece, scintiphoto, absorbing sheet, filter and backstay are rotary structure.
The invention has the beneficial effects as follows:
After gathering specimen of breath with solid scintillator bottle provided by the invention, insert scintillation counter and carry out flicker and measure, avoid suck-back that prior art exists, easily splash, the shortcoming of contaminated environment, troublesome poeration, while there is again higher measurement confidence level.
