[0002] Lumbar puncture is one of the basic operation skills that doctors must master, especially neurosurgeons, who must perform lumbar puncture examination for inflammatory lesions of the central nervous system, demyelinating diseases, brain tumors and subarachnoid hemorrhage, etc. The lumbar puncture kits currently in use are mostly self-assembled and configured by the hospital supply room. In addition to commonly used lumbar puncture needles, pressure measuring tubes, sterile gauze, etc., they generally include three or so sterile test tubes for the retention of cerebrospinal fluid for pathogen culture. The remaining cerebrospinal fluid specimens that do not require sterility are retained by the doctor in appropriate dry tubes as needed for the condition, usually by placing the dry tubes on a test-tube rack during the lumbar puncture operation, and placing the test-tube rack next to the lumbar puncture kit. The doctor takes the dry tubes to collect cerebrospinal fluid during the operation.

[0003] Most existing test-tube racks have only test-tube placement holes of a fixed size, and when test tubes of different sizes are used, multiple sizes of test-tube racks need to be prepared for placement, which results in resource waste if each set of test-tube racks is not fully occupied, and multiple test-tube racks occupy more space for placement. In addition, most existing test-tube racks do not have a limiting and anti-slip function for the test tubes. SUMMARY

[0004] The utility model aims at solving one of the technical problems existing in the prior art.

[0005] To this end, one object of the utility model is to provide a test-tube rack for lumbar puncture and cerebrospinal fluid retention, which can accommodate test tubes of multiple sizes and has a limiting and anti-slip function for the test tubes.

[0006] To achieve the above object, the utility model provides the following technical scheme: a test-tube rack for lumbar puncture and cerebrospinal fluid retention, comprising two side plates, a middle plate fixedly connected between the two side plates, a stopper fixedly connected to one side of each of the two side plates, a top plate provided on the stopper, a top placement slot arrayed on the top plate, a middle placement slot arrayed on the middle plate, three partition plates fixedly connected to the bottom of the middle plate, two groups of sliding frames slidingly connected to the outside of each of the three partition plates, a sponge strip fixedly connected to the inside of each of the three partition plates, the two groups of sliding frames located on the two sides of the sponge strip, and the sliding frames adhered to the outside of the sponge strip, two edge plates fixedly connected to the bottom of the middle plate, a group of side edge rubber pads fixedly connected to one side of each of the two edge plates, and a support plate mechanism installed between the two side plates.

[0007] Preferably, the supporting plate mechanism comprises a threaded connecting pipe, which is arranged on the bottom of the middle plate, a threaded rod is screwed in the threaded connecting pipe, a supporting plate is screwed on the threaded rod, four sliding blocks are fixedly connected to the outer part of the supporting plate, and a sliding rail is fixedly connected to the side of each of the two side plates.

[0008] Preferably, the number of the group of side rubber pads is the same as the number of the group of sliding frames.

[0009] Preferably, a sponge pad is attached to the outer part of the sliding frame.

[0010] Preferably, two handles are fixedly connected to the outer part of the top plate.

[0011] Preferably, the material of the side plates, the top plate and the middle plate is acrylic.

[0012] Compared with the prior art, the present application has the following advantages:

[0013] The sliding frame moves inward to press the sponge strip, the sponge strip and the side rubber pads on the side plates jointly fix the test tube, prevent the test tube from slipping off, and different specifications of test tubes can be limited by the sponge strip and the side plates.
