Description

Technical Field

[0001] The present invention relates to the technical field related to medical devices, and in particular to a rotatable test tube rack for testing. Background Art

[0002] The clinical laboratory serves as a bridge between clinical medicine and basic medicine, encompassing multiple sub-disciplines such as clinical chemistry, clinical microbiology, clinical immunology, hematology, fluidology, and transfusion medicine. The clinical laboratory is the department within a hospital or medical institution responsible for testing a variety of human and animal specimens. These specimens may come from wards, outpatient clinics, various physical examinations, and scientific research projects. Leveraging advanced equipment and expert technicians, the clinical laboratory is able to provide accurate and reliable test results, providing a crucial basis for clinical diagnosis and treatment.

[0003] The test tube racks currently used in clinical laboratories consist of two plastic plates connected by support plates on either side. The plates have multiple circular holes for inserting test tubes, while the lower plate supports the bottoms of the test tubes. This type of test tube rack is inconvenient to remove test tubes. Furthermore, in clinical laboratories, test tubes often need to be tilted to facilitate observation of cell or microbial sedimentation and promote oxygen transfer and carbon dioxide release. However, existing test tube racks are difficult to tilt test tubes, and the tilt angle cannot be accurately calculated. Summary of the Invention

[0010] Furthermore, the fixed plate and the movable plate are both arc-shaped structures, and anti-slip layers are provided on the arc-shaped concave surfaces of the fixed plate and the clamping plate.

[0011] Furthermore, the mounting frame includes a bottom ring, a vertical rod, a top ring, and a cross rod, and the bottom ring and the top ring are fixedly connected by a plurality of vertical rods; the bottom ring is fixedly connected to the rotating seat by a plurality of cross rods, and the rotating seat is rotatably mounted on the base; the top ring is fixedly connected to the mounting plate by a plurality of cross rods; the fixed seat of the test tube rack is rotatably mounted on the inner side of the top ring, and the telescopic column is fixedly mounted on the bottom ring, and a fixed slide groove is provided on the fixed plate, and the protruding end of the telescopic column is rotatably connected to the fixed plate through the fixed slide groove and slides along the fixed slide groove, and a screw is rotatably arranged in the telescopic column, and the extension and retraction of the telescopic column is controlled by rotating the screw, thereby driving the fixed plate to rotate.

[0015] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0016] 1. The mounting frame of the present invention is provided with a plurality of test tube racks in a circular array. The test tube racks are rotatably mounted on the mounting frame, and a plurality of telescopic columns are provided on the mounting frame corresponding to the test tube racks to respectively control the rotation of the test tube racks. When in use, the outer wall of the test tube is placed close to the fixed plate of the test tube rack, and the rotating rod is driven to rotate by rotating the rotating member, driving the elastic telescopic column to slide along the radial direction of the mounting plate, thereby driving the movable plate of the test tube rack to approach the fixed plate to squeeze and clamp the test tube, thereby fixing the test tube. The telescopic column is controlled to extend and retract by rotating the screw on the telescopic column, driving the fixed plate to rotate, thereby tilting the test tube rack and the test tube. The tilt angle can be adjusted by rotating the screw, which is convenient to operate.

The one-way screw rod is driven to rotate the two-way screw rod at the same time to adjust the distance between the two side rods according to the diameter of the tube, so that the elastic expansion plates on the two side rods can clamp the two sides of the test tube. The rotating member drives the movable plate to approach the test tube to compress the elastic expansion plate and clamp the test tube. The design of the U-shaped rod and the clamping plate can pre-fix the test tube, avoiding the test tube from being clamped by holding the test tube, and the cooperation between the clamping plate and the fixing plate can keep the test tube from slipping when the clamping of the movable plate is released, making it convenient to take out.
