Abstract
The utility model relates to an improvement of the medical test tube. The utility model is mainly characterized in that the nozzle of the existing flat opening gamma counter tube is improved into a dipped finish with an oriented bevel face, and the thickness of the wall of the base of the existing flat opening gamma counter tube is enlarged. The improvement prevents the tube seized phenomenon and prevents the base from leaking and splitting at the time of high speed centrifugation. The utility model is especially suitable for the radioimmunoassay of the cancer, the hyperthyroidism, the early pregnancy and the incretion disease. The utility model is favorable to the diagnosis and the treatment of the disease and the use and the maintenance of the test facility.
Description
The utility model relates to a kind of improvement of medical test tube.
At present, the shape and structure and the common test tube of the Y counter tube that medical institutions are commonly used are basic identical, and the mouth of pipe is the plane or omits outward flanging that the pipe bottom is owing to some cast gate, wall thickness attenuation.Above-mentioned Y counter tube commonly used falls in the well type measured hole of counter or measures to finish and lifted when resetting by push rod, is very easily blocked by well type guide, produces " card pipe " phenomenon, usually causes Y counter tube bump broken.Simultaneously, owing to must carry out 15-20 minute high speed centrifugation during test, 4000 rev/mins of turn ups, the seepage cracking usually appears in Y counter tube bottom, in case above-mentioned situation takes place, radioactive substance will flow out contaminated equipment in the pipe, and test job can not be carried out smoothly, causes delay treatment diagnosis and symptomatic treatment.
The purpose of this utility model is the above-mentioned shortcoming that overcomes existing Y counter tube, designs a kind of pipe that do not block, and intensity is big, and is non-leakage during high speed centrifugation, indehiscent safe Y counter tube.
The technical solution adopted in the utility model is the angle that the mouth of pipe of existing flat mouthful of Y counter tube is modified into a guiding surface, blocks pipe to avoid producing, and increases the bottom wall thickness, to increase counter tube intensity.Make it non-leakage cracking when high speed centrifugation.
Accompanying drawing is a longitudinal sectional view of the present utility model.
The 1-tube wall, the 2-guiding surface, 3-thickeies bottom.
It is 78mm that the designer has manufactured experimently a kind of pipe range, and caliber φ is the safe Y counter tube of 13mm, and it is 2.3mm that the mouth of pipe has guiding surface, and all wall thickness are 1mm, and the diapire maximum ga(u)ge is 1.3mm, single injection-molded.
The foregoing description of the present utility model, at 50 pipes, 200 pipes etc. have carried out test more than ten thousand times on the Y counter automatically, on the top, when falling to managing, because the mouth of pipe has guiding surface, have stopped the card pipe phenomenon that traditional Y counter tube often occurs.During high speed centrifugation, because the bottom wall thickness is big, intensity increases, and has avoided the bottom leaky cracking.The utility model is specially adapted to the radio-immunity test of cancer, hyperthyroidism, early pregnancy, endocrine system disease, helps the diagnoses and treatment of disease and the application maintenance of testing equipment.
Claims (1)
1, a kind of safe V counter tube is characterized in that the mouth of pipe has a guiding surface 2, and the thickness of bottom tube wall is greater than the wall thickness at other position.
