Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical supplies technology, specifically to a blood culture device. Background Art
[0002] During blood culture, test tubes or culture media need to be placed and stored in a storage box or rack. Currently, test tubes or culture media are typically fixed at a certain angle within the storage box or rack. When the storage box or rack needs to be moved, or when it needs to be placed on uneven ground for special reasons, the test tubes or culture media will tilt at a greater angle due to the tilt of the storage box or rack. This can easily affect the reaction efficiency of the substances in the test tubes or culture media, and may even cause substances to spill to the top of the test tubes or culture media, resulting in leakage or contamination, affecting the normal reaction, and potentially leading to the reaction not achieving the desired effect.
[0003] In view of the above-mentioned defects, the creator of this utility model has finally obtained this utility model after a long period of research and practice. Utility Model Content
[0004] To address the aforementioned technical deficiencies, the present invention provides a blood culture device comprising a frame, a rotating shaft, a placement section, and a configuration section. The two ends of the rotating shaft are rotatably connected to the frame. The placement section is fixedly mounted on the rotating shaft. The configuration section is mounted on the placement section. The placement section has several placement cavities in which test tubes or culture media are placed. The placement section can rotate freely around the axis of the rotating shaft. The configuration section is located at the lower end of the placement section to adjust the center of gravity of the placement section, causing the placement section to tilt.

DETAILED DESCRIPTION
[0021] The above-mentioned and other technical features and advantages of this utility model will be described in more detail below with reference to the accompanying drawings.
[0022] Example 1
[0023] like Figure 1 , Figure 2 As shown, Figure 1 This is a front view of the structure of the blood culture device; Figure 2 This is a side view of the structure of the blood culture device.
[0024] The blood culture device of this utility model includes a frame 1, a rotating shaft 2, a placement part 3, and a configuration part 4. The two ends of the rotating shaft 2 are rotatably connected to the frame 1. The placement part 3 is fixedly disposed on the rotating shaft 2. The configuration part 4 is disposed on the placement part 3. The placement part 3 is provided with a plurality of placement cavities 31. Test tubes or culture media are placed in the placement cavities 31. The placement part 3 can rotate freely around the axis of the rotating shaft 2. The configuration part 4 is disposed at the lower end of the placement part 3 to adjust the center of gravity of the placement part 3 so that the placement part 3 is tilted to achieve the tilted placement of the test tubes or culture media in the blood culture device.
[0025] Generally, the placement cavities 31 on the same placement part 3 are arranged in a straight line along the axial direction of the rotation shaft 2. The cross-section of the placement cavity 31 is set to be circular, and the axial direction of the placement cavity 31 is set perpendicular to the axial direction of the rotation shaft 2, thereby ensuring that the test tubes or culture media placed in each placement cavity 31 are tilted at the same tilt angle.
[0026] Preferably, the frame 1 includes a first frame 11 and a second frame 12. The first frame 11 includes a first top rod, a first bottom rod, and two first connecting rods. The two ends of the two first connecting rods are fixedly connected to the first top rod and the first bottom rod, respectively, to form a rectangular frame structure. The second frame 12 includes a second top rod, a second bottom rod, and two second connecting rods. The two ends of the two second connecting rods are fixedly connected to the second top rod and the second bottom rod, respectively. In use, the first connecting rods are generally vertically arranged, and the first connecting rods and the second connecting rods are connected in a one-to-one cross manner. The first bottom rods and the second bottom rods are on the same plane and arranged in parallel. The first bottom rods and the second bottom rods form a bottom support surface to facilitate placement on the ground or a tabletop. The first top rods and the second top rods facilitate users to lift the frame 1 for carrying and other operations, thereby forming a structure for placing the frame 1.
[0027] It is worth noting that the frame 1 may be surrounded by an isolation plate, and the isolation plate is provided on all six sides of the frame 1, thereby forming a box structure to protect the test tubes or culture medium placed in the placement cavity 31.
[0028] Preferably, multiple rotating shafts 2 are provided, and the two ends of each rotating shaft 2 are movably connected to two second connecting rods respectively. Each rotating shaft 2 is arranged in a straight line along the extension direction of the second connecting rod. Since the first connecting rod is generally in a vertical state during use, the second connecting rod is in an inclined state. In conjunction with the inclined placement parts 3, each placement part 3 has a large adjustment space and operating space.
[0029] This invention, by providing a placement part 3 that can rotate around an axis and in conjunction with the configuration part 4, ensures that the placement part 3 maintains a relatively stable tilted state under the action of gravity. When the frame 1 is moved, picked up, or tilted, the placement part 3 will still maintain its original tilted state under the action of gravity and will not undergo a large tilt change with the tilt of the frame 1. This avoids the impact of the overall transportation or tilting of the blood culture device on the reaction of substances in the test tubes or culture medium, thus ensuring the effective progress of the reaction.
[0030] Example 2
[0031] like Figure 3 As shown, Figure 3 The diagram shows a cross-sectional view of the placement part and the configuration part. The placement part 3 is a cuboid, and the top of the placement part 3 has an opening for the placement cavity 31. One side of the placement part 3 is fixedly connected to the corresponding rotating shaft 2 via a connecting seat 33, which facilitates the placement part 3 to tilt to the other side and ensures the tilting setting of the placement cavity 31.
[0032] The configuration part 4 includes a fixed counterweight 41 and an adjustable counterweight 42. The fixed counterweight 41 is fixedly disposed at the bottom of the placement part 3, and the adjustable counterweight 42 is disposed on the other side away from the connecting seat 33. The fixed counterweight 41 and the adjustable counterweight 42 are in contact with each other, so that the overall center of gravity of the placement part 3 and the configuration part 4 is close to the connection position of the fixed counterweight 41 and the adjustable counterweight 42, thereby achieving stable tilting of the placement cavity 31.
[0033] Generally, both the fixed counterweight 41 and the adjusting counterweight 42 are rectangular flat plates. The fixed counterweight 41 is fixedly installed at the bottom of the placement part 3. A magnet 32 is embedded in one side of the placement part 3. The adjusting counterweight 42 is made of iron. The adjusting counterweight 42 is connected to the placement part 3 by the attraction of the magnet 32. By adjusting the weight of different adjusting counterweights 42, the overall center of gravity of the placement part 3 and the configuration part 4 can be adjusted, thereby adjusting the tilt angle of the placement cavity 31.
[0034] Preferably, the fixed counterweight 41 is fixedly disposed at the bottom of the placement part 3 and one side extends out from the bottom of the placement part 3, and the bottom of the adjusting counterweight 42 is perpendicularly connected to the extended part of the fixed counterweight 41, thereby ensuring that the position of the adjusting counterweight 42 on the placement part 3 is stable.
[0035] Example 3
[0036] like Figure 4 As shown, Figure 4 The diagram shows the structure of the rotating shaft 2. Limiting blocks 21 and fixing blocks 22 are respectively provided at both ends of the rotating shaft 2. The frame 1 is positioned between the limiting blocks 21 and the fixing blocks 22. The limiting blocks 21 are fixedly disposed at the end of the rotating shaft 2 and engage with the corresponding second connecting rod to achieve a limiting operation. The fixing blocks 22 have threaded holes, and the end of the rotating shaft 2 is threaded into these holes. By rotating the fixing blocks 22 and the rotating shaft 2 relative to each other, the limiting blocks 21 and the fixing blocks 22 can be brought into contact with or moved away from the corresponding second connecting rod, thereby locking the rotating shaft 2 and preventing it from rotating around its own axis.
[0037] The structure of the limiting block 21 and the fixing block 22 allows for control of the rotation state of the rotating shaft 2, thereby locking the state of the rotating shaft 2 when placing or removing test tubes or culture media, preventing the placement part 3 from shaking, facilitating placement, and locking the position when the placement part 3 is in a better tilt state.
[0038] Preferably, rubber washers 23 are provided between the limiting block 21 and the corresponding second connecting rod, and between the fixing block 22 and the corresponding second connecting rod. The rubber washers 23 increase the relative friction between the limiting block 21 and the fixing block 22 and the corresponding second connecting rod, making it easier to lock the rotating shaft 2.
[0039] The above description is merely a preferred embodiment of the present utility model and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
