Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a blood collection stand for testing. Background Technology

[0002] Blood sample tube holders are indispensable auxiliary equipment in hospital laboratories and other medical analysis facilities. Their core function is to provide a safe, orderly, and easily accessible temporary storage space for a large number of blood collection tubes (such as vacuum blood collection tubes and EDTA tubes) awaiting or already tested. The mainstream design generally adopts a double- or multi-layered stacked structure, with each layer precisely cut with a circular opening of uniform diameter. The openings in the upper and lower layers are strictly aligned to form a vertical cylindrical cavity to accommodate the blood collection tubes. While this standardized design facilitates mass production and vertical insertion of the tubes, its inherent rigid structure brings significant operational risks and compatibility limitations.

[0003] In practical applications, there are a wide variety of blood collection tube specifications, especially when there are significant differences in tube diameter. This includes long, thin blood collection tubes with a diameter significantly smaller than the orifice diameter, such as those used in certain specialized tests. In these cases, the tubes cannot obtain sufficient lateral support and are prone to tilting, shifting, or even colliding with adjacent tubes within the cavity. Furthermore, during frequent sample handling, such as when staff move the support, these poorly secured tubes are easily dislodged or fall due to inertia or shaking. This not only directly damages precious blood samples but also poses a risk of physical injury from sharp plastic fragments. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where slender blood collection tubes with a diameter significantly smaller than the opening diameter cannot obtain sufficient lateral support, making them prone to tilting, shifting, or even colliding with adjacent tubes within the cavity. This invention proposes a blood collection stand for testing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: Design a blood collection rack, including two parallel support plates with a gap between them. A base plate is bolted to the bottom between the two support plates, and a locking plate is bolted to the top between the two support plates. The locking plate has several placement slots, and each of the placement slots has a pair of locking blocks. The locking plate has an adjustment mechanism connected to the locking blocks. The adjustment mechanism includes several through slots formed on the card plate, each through slot passing through a corresponding placement slot. One end of several pairs of card blocks is slidably disposed in the through slot. Fixing plates are provided on both sides of the card plate, and several elastic elements are provided on the fixing plates. One end of each elastic element is connected to the other end of the corresponding card block.

[0006] Preferably, each of the through slots is provided with a limiting slot, and a limiting strip is correspondingly provided on the card block, the limiting strip slidingly engaging within the limiting slot.

[0007] Preferably, the elastic element is a compression spring, the card plate is provided with a limiting rod, one end of the limiting rod extends into the corresponding card block and leaves a sliding groove, and the elastic element is sleeved on the limiting rod.

[0008] Preferably, the base plate is provided with a movable plate, the movable plate is slidably disposed between two support plates, and an adjustment component is provided inside the base plate, the adjustment component being connected to the movable plate.

[0009] Preferably, the adjustment assembly includes a connecting groove formed on the base plate, a threaded rod connected to the connecting groove via a bearing, a movable rod threadedly connected to the threaded rod, the movable rod slidingly fitting within the connecting groove, and a plurality of parallel connecting rods hinged to the movable rod, one end of each of the plurality of connecting rods being hinged to one side of the bottom of the movable plate.

[0010] Preferably, after the bottom of the movable plate is attached to the top of the base plate, all of the connecting rods are in an inclined state.

[0011] Preferably, one end of the threaded rod passes through the base plate and one of the support plates in sequence and is equipped with a handle.

[0012] Preferably, the outer peripheral surface of the handle is provided with anti-slip texture.

[0013] The blood collection rack proposed in this utility model has the following advantages: 1. By squeezing the card block with the elastic element, the card block is transmitted and evenly applied to the outer wall of the blood collection tube. The blood collection tube is stably and firmly constrained in the corresponding placement groove, making it less likely for the blood collection tube to slip off. This provides safety for the blood collection tube during placement and allows the device to be compatible with blood collection tubes of different diameters within a certain range, thereby improving the practicality of the device. 2. By rotating several connecting rods and changing their tilt angle, the moving plate is driven to rise and fall between the two support plates. When the moving plate rises to a suitable height, its top surface replaces the bottom plate to support the bottom of the blood collection tube, eliminating the suspended state and reducing the risk of the blood collection tube slipping.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1: Refer to Figure 1-6 A blood collection rack includes two parallel support plates 1 with a gap between them. A base plate 2 is fixedly installed at the bottom between the two support plates 1 by bolts. A clamping plate 3 is fixedly installed at the top between the two support plates 1 by bolts. The clamping plate 3 has several placement slots 4, and each of the several placement slots 4 is provided with a pair of clamping blocks 5. An adjustment mechanism is provided on the clamping plate 3, and the adjustment mechanism is connected to the clamping blocks 5. The adjustment mechanism includes several through slots 6 formed on the card plate 3, with the through slots 6 passing through the corresponding placement slots 4 respectively. One end of several pairs of card blocks 5 is slidably disposed in the through slots 6. Fixing plates 7 are provided on both sides of the card plate 3, and several elastic elements 8 are provided on the fixing plates 7. One end of the elastic elements 8 is connected to the other end of the corresponding card block 5.

[0023] During use: After inserting blood collection tubes of different diameters into the placement groove 4 in sequence, the outer side of the blood collection tube will come into contact with the symmetrically arranged locking blocks 5 on both sides of the groove and apply a squeezing force. The two locking blocks 5 will squeeze the corresponding elastic elements 8 respectively, so that one end of the two locking blocks 5 will enter the through groove 6. Under the squeezing action of the outer wall of the blood collection tube, the two locking blocks 5 are forced to overcome the resistance and move along the predetermined path in a direction away from the center of the blood collection tube. The locking blocks 5 directly compress the corresponding elastic elements 8, causing them to deform. As the locking blocks 5 continue to move, their inner ends enter the reserved through groove 6; at the same time, the compressed elastic elements 8 store elastic potential energy due to deformation. The stored energy keeps the elastic elements 8 in a state of stored force and continuously generates a reverse force pointing towards the center of the blood collection tube, which is transmitted through the locking blocks 5 and evenly applied to the outer wall of the blood collection tube. The blood collection tube is stably and firmly constrained in the corresponding placement groove 4, making it less likely for the blood collection tube to slip off, thus providing safety during the placement process.

[0024] Example 2: An optimization based on Example 1, with reference to... Figure 1-6 Each of the several through slots 6 is provided with a limiting slot 9, and a corresponding limiting strip 10 is provided on the card block 5. The limiting strip 10 slides in the limiting slot 9, so that the two card blocks 5 in the placement slot 4 will not close relative to each other, thereby reducing the difficulty of placing the blood collection tube. The elastic element 8 is set as a compression spring, and a limiting rod 11 is provided on the card plate 3. One end of the limiting rod 11 extends into the corresponding card block 5 and leaves a sliding groove 12. The elastic element 8 is sleeved on the limiting rod 11, thereby reducing the probability of the elastic element 8 bending to the side and increasing the service life of the elastic element 8.

[0025] Example 3: In Example 1, when a batch of blood collection tubes is not long enough, after the clamping plate 3 holds the blood collection tubes, the bottom of the tubes is easily left suspended, which increases the risk of the tubes slipping. An optimization is made based on Example 1, referencing... Figure 1-6 A movable plate 13 is provided on the base plate 2. The movable plate 13 is slidably disposed between two support plates 1. An adjustment assembly is provided inside the base plate 2. The adjustment assembly is connected to the movable plate 13. The adjustment assembly includes a connecting groove 14 opened on the base plate 2. A threaded rod 15 is connected to the connecting groove 14 through a bearing. A movable rod 16 is threadedly connected to the threaded rod 15. The movable rod 16 is slidably fitted in the connecting groove 14. Several parallel connecting rods 17 are hinged to the movable rod 16. One end of each of the several connecting rods 17 is hinged to one side of the bottom of the movable plate 13.

[0026] Usage process: Rotating the threaded rod 15 can drive the moving rod 16 to slide along the connecting groove 14. The moving rod 16 then drives several connecting rods 17 to rotate and change their tilt angle. Since the moving plate 13 slides between the two support plates 1, it drives the moving plate 13 to rise and fall between the two support plates 1. When the moving plate 13 rises to a suitable height, its top surface replaces the bottom plate 2 to support the bottom of the blood collection tube, eliminating the suspended state and reducing the risk of the blood collection tube slipping.

[0027] Example 4: In Example 3, after several connecting rods 17 are in a parallel state with the base plate 2, the moving plate 13 is difficult to adjust. An optimization is made based on Examples 1-3, referencing... Figure 1-6 After the bottom of the movable plate 13 is attached to the top of the base plate 2, several connecting rods 17 are tilted, so that the connecting rods 17 are not in a horizontal position at the initial position, reducing possible jamming during the adjustment process; one end of the threaded rod 15 passes through the base plate 2 and one of the support plates 1 in sequence and is equipped with a handle 18. The outer circumferential surface of the handle 18 is provided with anti-slip texture, which reduces the rotational resistance of the threaded rod 15 and makes the device operation more convenient and labor-saving.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
