Description

Technical Field

[0001] This utility model relates to the technical field of test tube storage devices, and in particular to a multi-purpose blood collection test tube storage device. Background Technology

[0002] In the field of medical testing, blood collection tubes are the core tool for blood sample collection and storage. Their standardized management and safe transportation directly affect the accuracy of test results and operational efficiency. Traditional blood collection tube storage devices usually adopt a fixed slot or rigid bracket design, which can only accommodate tubes of specific sizes. This leads to the need for various models of storage devices in clinical use to accommodate tubes of different diameters.

[0003] Existing technology, such as CN220780454U, discloses a blood collection tube storage device, including a base plate. A fixing component is snapped into the bottom of the base plate, and several rubber plates are fixedly connected to the top of the base plate. External rods are fixedly connected to both sides of each rubber plate. This blood collection tube storage device, through the arrangement of the base plate and fixing component, connects an L-shaped plate to the bottom of the base plate, and then connects the L-shaped plate to the table in the sampling area. Rotating the handle drives the threaded rod to move, thereby moving the limiting plate to a suitable position, which helps to fix the storage device for the blood collection tubes and prevents the storage device from falling and being damaged.

[0004] To address this issue, some devices employ semi-circular clamps equipped with springs. The test tubes are held in place by the springs. However, to hold the test tubes using the springs and semi-circular clamps, the distance between the two semi-circular clamps must first be increased to allow the test tubes to pass smoothly between them. Only then can the test tubes be held in place by the elasticity of the springs. This process is quite cumbersome, and storing the test tubes takes a considerable amount of time, making it difficult for users to quickly store and retrieve them. Utility Model Content

[0005] In view of the above-mentioned problems that the existing methods of clamping test tubes are cumbersome and take a long time to store and use test tubes, which are not conducive to users' quick storage and retrieval, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a multi-purpose blood collection tube storage device, which aims to enable rapid storage and retrieval of test tubes on the storage device.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a multi-purpose blood collection tube storage device, including a chassis, with columns fixed at the four corners of the top of the chassis, and a crossbeam plate installed between the tops of the four columns. The top of the chassis has rectangularly distributed bottom support grooves, and the top of the crossbeam plate, directly above each bottom support groove, has a fixing hole. The upper and lower bottom support grooves and the fixing holes are coaxially arranged. A blood collection tube is placed between the coaxial bottom support grooves and the fixing holes. A multi-size clamping component for clamping and locking the blood collection tube is detachably installed at the bottom of the crossbeam plate, directly opposite each fixing hole.

[0008] The multi-size clamping assembly includes an annular plate that is detachably installed at the bottom of the crossbeam plate. The annular plate has a tube hole in the middle for the blood collection tube to pass through. The peripheral surface of the annular plate is integrally formed with side protrusions at equal intervals. A clamping strip is rotatably installed on the bottom of the side protrusion and on the side near the tube hole. The blood collection tube is clamped between the three clamping strips. A vertical spring is provided on the bottom of the side protrusion and on the side of the clamping strip away from the tube hole. The vertical spring abuts against the side of the clamping strip.

[0009] As an improved technical solution, two shaft blocks are fixedly installed at the bottom of each side protrusion, and a rotating shaft is rotatably installed between the two shaft blocks, with the end of the clamping strip near the side protrusion sleeved on the rotating shaft.

[0010] As an improved technical solution, a safety cavity is provided at the end of the clamping bar away from the rotation axis and on the side away from the vertical spring piece. A rubber block is bonded inside the safety cavity, and a bevel is provided at the upper end of the rubber block.

[0011] As an improved technical solution, each of the side protrusions is also fixed with a fixing vertical strip at its bottom, and a V-shaped spring strip is fixedly connected between the fixing vertical strip and the bottom of the vertical spring piece.

[0012] As an improved technical solution, a fixing block is welded to the peripheral surface of the annular plate and between two adjacent side protrusions. The top of the fixing block is provided with a positioning hole. An internal threaded sleeve is fixed to the bottom of the chassis and directly above each positioning hole. A locking screw is threaded on one end of the internal threaded sleeve near the clamping bar, and the threaded connection between the locking screw and the internal threaded sleeve allows the fixing block to be detachably installed on the bottom of the crossbeam plate.

[0013] As an improved technical solution, the chassis has rotating shafts mounted on both sides of the front and back, and a lifting strap is fixed between the front and rear rotating shafts on the same side.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are:

[0015] 1. In this utility model, when the blood collection tube passes between the three clamping strips, the blood collection tube will automatically open the three clamping strips and clamp the blood collection tube between the three clamping strips, realizing that the blood collection tube is fixed upon insertion and released upon removal, which facilitates quick clamping and locking of the blood collection tube. Moreover, the opening degree of the three clamping strips is different for blood collection tubes of different sizes. At the same time, the setting of vertical spring not only can accommodate blood collection tubes of different sizes for clamping, but also improves the firmness of clamping the blood collection tube.

[0016] 2. In this utility model, three internally threaded sleeves are inserted into the positioning holes, and then locking screws are screwed in from the bottom of the internally threaded sleeves. The annular plate is clamped and fixed to the bottom of the crossbeam plate by the locking screws. The fixing by screws makes it easy to assemble multi-size clamping components at the bottom of the crossbeam plate. On the other hand, undamaged multi-size clamping components can be disassembled and reused to avoid waste. Attached Figure Description

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Example 1

[0025] Reference Figures 1-3 This is the first embodiment of the present invention, which provides a multi-purpose blood collection tube storage device. This multi-purpose blood collection tube storage device includes a base plate 1, with columns 3 fixed at the four corners of the top of the base plate 1. A crossbeam plate 5 is installed between the tops of the four columns 3. The top of the base plate 1 has rectangularly distributed bottom support grooves 2. The top of the crossbeam plate 5 and directly above each bottom support groove 2 has a fixing hole 4. The upper and lower bottom support grooves 2 and the fixing holes 4 are coaxially arranged. A blood collection tube 7 is arranged between the coaxial bottom support grooves 2 and the fixing holes 4. A multi-size clamping component 6 for clamping and locking the blood collection tube 7 is detachably installed at the bottom of the crossbeam plate 5 and directly opposite each fixing hole 4.

[0026] The multi-size clamping assembly 6 includes an annular plate 61 that is detachably installed at the bottom of the crossbeam plate 5. The annular plate 61 has a tube hole 62 in the middle for the blood collection tube 7 to pass through, and the tube hole 62 and the fixing through hole 4 are coaxially arranged. The peripheral surface of the annular plate 61 is integrally formed with side protrusions 64 at equal intervals. A clamping strip 68 is rotatably installed on the bottom of the side protrusion 64 and on the side near the tube hole 62. The blood collection tube 7 is clamped between the three clamping strips 68. A vertical spring piece 69 is provided on the bottom of the side protrusion 64 and on the side of the clamping strip 68 away from the tube hole 62. The vertical spring piece 69 abuts against the side of the clamping strip 68.

[0027] Two shaft blocks 681 are fixedly installed at the bottom of each side protrusion 64. A rotating shaft 682 is rotatably installed between the two shaft blocks 681, and the end of the clamping bar 68 near the side protrusion 64 is sleeved on the rotating shaft 682.

[0028] A safety cavity 683 is provided at the end of the clamping bar 68 away from the rotating shaft 682 and on the side away from the vertical spring piece 69. A rubber block 684 is bonded inside the safety cavity 683, and a bevel is provided at the upper end of the rubber block 684. The rubber block 684 will increase the friction coefficient between it and the blood collection tube 7, thereby improving the firmness of clamping the blood collection tube 7.

[0029] Each side protrusion 64 is also fixed with a fixing vertical bar 691 at its bottom, and a V-shaped spring strip 692 is fixedly connected between the fixing vertical bar 691 and the bottom of the vertical spring 69.

[0030] During use, when the blood collection tube 7 passes between the three clamping strips 68, the blood collection tube 7 will automatically open the three clamping strips 68 and clamp the blood collection tube 7 between the three clamping strips 68, so that the blood collection tube 7 is fixed when inserted and released when pulled out, which facilitates quick clamping and locking of the blood collection tube 7. The opening degree of the three clamping strips 68 is also different for different sizes of blood collection tubes 7. At the same time, the setting of the vertical spring 69 can not only adapt to the clamping of blood collection tubes 7 of different sizes, but also improve the firmness of the clamping of the blood collection tube 7.

[0031] Example 2

[0032] Reference Figures 1-2 This is the second embodiment of the present invention. This embodiment differs from the first embodiment in that: a fixing block 66 is welded to the peripheral surface of the annular plate 61 and between two adjacent side protrusions 64. The top of the fixing block 66 is provided with a positioning hole 63. An internal threaded sleeve 65 is fixed to the bottom of the chassis 1 and directly above each positioning hole 63. The bottom end of the internal threaded sleeve 65 is inserted into the interior of the positioning hole 63. A locking screw 67 is threadedly installed on the end of the internal threaded sleeve 65 near the clamping bar 68. The locking screw 67 and the internal threaded sleeve 65 are threadedly connected to detachably install the fixing block 66 on the bottom of the crossbeam plate 5 and fix it by screws. On the one hand, it is convenient to assemble the multi-size clamping assembly 6 on the bottom of the crossbeam plate 5. On the other hand, the undamaged multi-size clamping assembly 6 can be disassembled and reused to avoid waste.

[0033] The chassis 1 has rotating shafts mounted on both sides of the front and back. A carrying strap 8 is fixed between the front and rear rotating shafts on the same side. By rotating the carrying straps 8 on both sides towards the center at the same time, the two carrying straps 8 are joined together. By holding the two carrying straps 8 in your hand, you can carry the storage device. When there is no trolley, box or other means of transportation, the device can be carried by carrying it, without having to hold the device by hand, thus improving the convenience of use.

[0034] During use, the process of installing the multi-size clamping assembly 6 at the bottom of the crossbeam plate 5 is as follows:

[0035] Three internal threaded sleeves 65 are inserted into the positioning holes 63, and then locking screws 67 are screwed into the bottom of the internal threaded sleeves 65 to clamp and fix the annular plate 61 to the bottom of the crossbeam plate 5.

[0036] The remaining structure is the same as that in Example 1.

[0037] Based on embodiments 1-2, the working principle of this utility model is as follows: When the blood collection tube 7 is inserted into the fixed perforation 4, under the limiting action of the three clamping strips 68 of the multi-size clamping component 6, when the blood collection tube 7 is inserted downward, it will guide the tube, so that the blood collection tube 7 is kept in the middle position and moves downward, that is, the bottom groove 2, the fixed perforation 4 and the blood collection tube 7 are kept in a coaxial state.

[0038] When the bottom of the blood collection tube 7 contacts the rubber block 684, if the blood collection tube 7 continues to move downward, it will push the clamping strip 68 to rotate counterclockwise and compress the vertical spring 69. Under the elastic counter-pushing action of the clamping strip 68, the clamping strip 68 rotates in the opposite direction, causing the rubber block 684 to rotate clockwise and apply pressure to the blood collection tube 7, clamping the blood collection tube 7 between the three clamping strips 68.

[0039] When the blood collection tube 7 is lifted up to detach from the contact with the rubber block 684, the three vertical springs 69 will trigger the clamping strip 68 to reset under the elastic reset of the vertical spring 69.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
