Embodiment Construction

[0016] From figure 1 , figure 2 , image 3 As can be seen in the figure, a test tube leakage detection device is provided with a support 1, a test tube suction cup 2, a vacuum pump 5, a test tube suction cup turning mechanism, a water tank 12, an electrical console 7, etc., and the test tube suction cup turning mechanism is installed on the support 1 , which includes a motor 8, a reducer 9, and a turning body 10. The motor 8 decelerates and changes direction through the reducer 9, and transmits power to the rotating shaft of the turning body 10, and the turning body 10 is driven by the rotating shaft to achieve a controllable turning within a range of 180 degrees. ,position. The specific composition, structure and connection relationship of the overturning mechanism belong to the prior art and will not be repeated here. The test tube suction cup 2 of the test tube leak detection device is installed and fixed on the turning body 10, and is driven by the motor 8 to perform f...

Abstract

The invention relates to an apparatus used for detecting test tube leakages. The apparatus is provided with a support, a test tube sucker, a vacuum pump, a sucker overturn mechanism, a water tank and an electrical control bench. The sucker overturn mechanism comprises a motor, a decelerator and an overturn body. The test tube sucker is fixedly arranged on the overturn body and is respectively in three position states of vertical, sucker surface horizontal upward and sucker surface horizontal downward. The test tube sucker surface is neatly provided with a plurality of pores. An airway communicating with the pores is provided inside the test tube sucker. The airway is connected to the vacuum pump through a connecting flexible pipe. The water tank is provided on the support. According to the invention, the test tube sucker and the vacuum pump are adopted to adhesively fix a test tube. The overturn mechanism of the test tube sucker is used to drive the test tube sucker loading the test tube to overturn and position and the bottom of the vacuum-pumping test tube is immersed into the water tank so as to inspect whether leakages exist or not. The apparatus is characterized by simple structure, reasonable construction, convenient airtight detection, fastness, accuracy and reliability and high working efficiency and is particularly suited for leakage detections towards test tubes used as vacuum heparin tubes.

Description

technical field [0001] The invention relates to a medical vacuum blood collection tube quality detection device, in particular to a test tube leakage detection device. Background technique [0002] We know that the one-time closed vacuum blood collection technology is the standard blood collection technology recommended by NCCLS. Since the blood collection procedure is completed under a fully closed system, the possibility of blood contamination and cross-infection is fundamentally ruled out; and because of its simple structure, it is easy to use Convenience, so easy to popularize and promote, has been widely used in hospitals at all levels. Because of its clean, safe, simple, fast, accurate, reliable, convenient and economical features, vacuum blood collection tube blood drawing is inevitable for the development of medical technology, and is one of the necessary contents for laboratory certification and hospital ISO certification. Disposable vacuum blood collection tube co...
