Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to a preservation device for test samples. Background Art
[0002] The clinical laboratory is a bridge between clinical medicine and basic medicine. It undertakes the detection work of various human or animal specimens including inpatients, emergency patients, various physical examinations, and scientific research every day, including various comprehensive biochemical examinations, liver function examinations, blood ammonia, renal function examinations, blood tests, urine tests, and so on.
[0003] In medical operations, medical staff often need to draw the patient's blood samples into test tubes and place these test tubes securely in specific holes of a test tube rack. The diameter of these holes is usually slightly larger than the diameter of the test tubes to facilitate the smooth placement of the test tubes. However, when medical staff lift or move the test tube rack for inspection, due to the small gap between the holes and the test tubes, the test tubes are prone to shaking. This shaking may cause the blood samples in the test tubes to be vibrated, which may in turn cause the red blood cells to be damaged and rupture, releasing hemoglobin. This process may affect the subsequent test results of blood components and reduce the accuracy and reliability of diagnosis. Content of the Utility Model
[0004] Aiming at the deficiencies of the existing technology, the utility model provides the following technical solution: a preservation device for test samples, including a test tube rack body. A placement mechanism for fixing test tubes is arranged inside the test tube rack body. A horizontal card slot is opened on the left inner wall of the test tube rack body. A rotary handle is rotatably connected to the front side of the test tube rack body. The rear end of the rotary handle penetrates the front inner wall of the horizontal card slot and extends into the horizontal card slot. A rotating rod is fixedly installed at the end of the rotary handle extending into the horizontal card slot. Thread groove groups are arranged on the outer side of the rotating rod. A moving clamping block is connected to the thread groove groups by threads. The moving clamping block is movably clamped with the horizontal card slot. A clamping plate is fixedly installed at the right end of the moving clamping block. A plastic arc plate is arranged on the front side of the clamping plate.
[0005] As an improvement of the above technical solution, the placement mechanism includes lower holes opened on the bottom inner wall of the test tube rack body. Slot handles are opened on both the left and right sides of the test tube rack body. A fixing plate is fixedly installed on the left inner wall of the test tube rack body and above the horizontal card slot. An upper hole is opened at the top of the fixing plate. The test tubes are preliminarily fixed through the cooperation of the placement mechanisms.
[0006] As an improvement of the above technical solution, the thread groove group includes a first thread groove and a second thread groove, and the first thread groove and the second thread groove are symmetrically designed and opened on the outer side of the rotating rod, so that when the rotating rod rotates, the first thread groove and the second thread groove respectively drive the moving blocks on both sides to move towards the center of the upward hole.
[0007] As an improvement of the above technical solution, the diameter of the upward hole is slightly larger than the diameter of the plastic arc plate, increasing the contact area between the plastic arc plate and the test tube when clamping and fixing the test tube.
[0008] The beneficial effects of the present utility model: Before lifting or moving the test tube, the plastic arc plates on both sides clamp and fix the test tube through the cooperation of the structure, increasing the stability of the test tube placed in the test tube rack body, preventing the blood sample inside from shaking when moving the test tube, reducing the possibility of red blood cells being damaged and ruptured to release hemoglobin, thereby increasing the stability of the blood sample and improving the accuracy and reliability of the diagnosis.

Detailed Description of the Invention
[0013] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0014] Refer to the attached Figure 1 , in Figure 1 The a direction points to the front view and the b direction points to the right side view, and the above views are only for understanding the solution.
[0015] Please refer to Figures 1-3, the present utility model provides a technical solution: a test sample storage device, including a test tube rack 1. Inside the test tube rack 1, there is a placement mechanism for fixing test tubes. On the left inner wall of the test tube rack 1, a horizontal card slot 3 is opened. The front side of the test tube rack 1 is rotatably connected to a turning handle 31. The rear end of the turning handle 31 penetrates the front inner wall of the horizontal card slot 3 and extends into the horizontal card slot 3. One end of the turning handle 31 extending into the horizontal card slot 3 is fixedly installed with a rotating rod 32. A thread groove group 33 is opened on the outer side of the rotating rod 32. The thread groove group 33 is threadedly connected to a moving clamping block 34. The moving clamping block 34 is movably clamped with the horizontal card slot 3. The right end of the moving clamping block 34 is fixedly installed with a clamping plate 35. On the front side of the clamping plate 35, there is a plastic arc plate 36.
[0016] Specifically, the placement mechanism includes a lower hole 2, which is opened on the bottom inner wall of the test tube rack 1. On both the left and right sides of the test tube rack 1, there are notch grips 21. On the left inner wall of the test tube rack 1 and above the horizontal card slot 3, a fixed plate 22 is fixedly installed. On the top of the fixed plate 22, an upper hole 23 is opened.
[0017] In this embodiment, the test tubes are preliminarily fixed through the cooperation between the placement mechanisms.
[0018] Specifically, the thread groove group 33 includes a first thread groove and a second thread groove, which are symmetrically designed and opened on the outer side of the rotating rod 32.
[0019] In this embodiment, when the rotating rod 32 rotates, the first thread groove and the second thread groove respectively drive the moving clamping blocks 34 on both sides to move towards the center of the upper hole 23.
[0020] Specifically, the diameter of the upper hole 23 is slightly larger than the diameter of the plastic arc plate 36.
[0021] In this embodiment, the contact area between the plastic arc plate 36 and the test tube is increased when clamping and fixing the test tube.
[0022] In use, medical staff draw the patient's blood sample into a test tube and place these test tubes securely in the holes 23 on the fixing plate 22, such that the bottom of the test tube is placed in the lower hole 2. When the medical staff need to hold the notch grip 21 to lift or move the test tube rack 1 for testing the test tube, they need to rotate the turning handle 31 in advance. The turning handle 31 drives the rotating rod 32 to rotate, and the rotating rod 32 drives the threaded groove group 33 to move. When the threaded groove group 33 rotates, it drives the moving blocks 34 on both sides to move synchronously towards the center of the upper hole 23 under the restriction of the horizontal card slot 3. The moving blocks 34 on both sides drive the clamping plates 35 on both sides to move towards the center of the upper hole 23 respectively. The clamping plates 35 on both sides drive the plastic arc plates 36 on both sides to move towards the center of the upper hole 23 respectively. When the plastic arc plates 36 on both sides move towards the center of the upper hole 23, they clamp and fix the test tube. The test tube is fixed by the plastic arc plates 36 on both sides. Since the diameters of the lower hole 2 and the upper hole 23 are slightly larger than the diameter of the test tube, it prevents the test tube from vibrating during the lifting or moving process, thereby increasing the stability of the blood sample and improving the accuracy and reliability of the diagnosis.
[0023] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
