Technical Field

The invention relates to the technical field of medical instruments, in particular to a layered test tube rack.

Background

Test tubes, instruments commonly used for chemical assays, are used as reaction vessels for small amounts of reagents, and are used at ambient or heated temperatures (which should be preheated before heating or the test tubes easily burst). The test tubes include common test tubes, test tubes with a support, centrifugal test tubes and the like. Urine routine examination is one of three routine projects of medical examination, urine is noninvasive and easy to collect, related components of proteinuria can appear in early stage of kidney diseases, and the urine routine examination has important reference values on certain systemic diseases and diseases such as diabetes, hematopathy, hepatobiliary diseases, epidemic hemorrhagic fever and the like, wherein urine influences urine changes by other organs of a body. Simultaneously, the chemical examination of urine can also reflect the treatment of some diseases, and consequently, clinical demand is higher, when carrying out the urine inspection to the patient, needs put urine and collect in the test tube, then puts the test tube on the test-tube rack, and medical staff takes test tube and test-tube rack away afterwards and carries out the urine inspection, and the test-tube rack plays very important effect as a universal test tube carrier.

At present, the existing test tube rack has the following defects:

1. at present, the number of test tubes carried by a test tube rack is small, most test tubes are spliced by a plurality of groups of test tube racks and then are placed in a frame or a box for use, the use is troublesome, and certain limitations are realized;

2. meanwhile, when the opened test tubes need to be sealed in the later period, medical staff need to cover the test tubes one by one, so that the work burden of the medical staff is greatly increased, and the urine detection efficiency is influenced;

3. and, when later stage clearance test tube, current test-tube rack needs the manual work to take off the test tube, abandons the test tube, when taking off the test tube, the urine spills probably to appear, can't concentrate and empty, the time of extension processing test tube.
