Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically, to a blood collection tube storage device. Background Technology

[0002] The content in this section only provides background information related to this invention and may not constitute prior art.

[0003] In the diagnosis process, blood tests are usually required to accurately assess a patient's condition. These tests provide a quick and direct understanding of various indicators of the patient's body, enabling doctors to understand the patient's situation and provide targeted treatment. During the diagnosis and treatment process, blood samples are required for different tests, such as liver function, kidney function, thyroid function, blood sugar, and electrolytes. In practice, these tests are usually performed independently, which necessitates multiple blood collections. To distinguish the tests corresponding to different blood collection tubes, several different colored blood collection tubes are prepared, and labels with different colors are attached to indicate the different blood test items.

[0004] In practice, after blood collection, medical staff need to manually shake the blood collection tube to ensure that the anticoagulant inside the tube mixes thoroughly with the blood, thus preventing clotting. However, when there are many patients, the medical staff are busy, and some blood collection tubes may clot due to uneven shaking, which can negatively impact subsequent blood tests, requiring blood to be collected again, wasting blood and increasing the workload of the medical staff. Summary of the Invention

[0016] In summary, the technical solutions of the embodiments of the present invention have at least the following advantages and beneficial effects:

[0017] 1. After blood collection is completed, the blood collection tube is placed in the receiving tank. Then, the reciprocating component drives the mounting block to reciprocate. During the reciprocating deflection of the mounting block, the mounting plate is deflected. As the mounting plate deflects, the blood collection tube in the receiving tank shakes, which allows the blood in the blood collection tube to mix fully with the anticoagulant, effectively preventing blood clotting.

[0018] 2. The drive motor drives the transmission shaft to rotate. As the transmission shaft rotates, the rotating disk rotates, which in turn drives the mounting shaft to rotate. As the mounting shaft rotates, the gear on the drive ring rotates. Since the gear meshes with the tooth groove, the rotating shaft rotates. As the rotating shaft rotates, the mounting block and mounting plate deflect. When the gear disengages from the tooth groove, the mounting shaft deflects back under the action of the first elastic element, which can make the blood collection tube shake, effectively improving the mixing of blood and anticoagulant and avoiding the phenomenon of blood clotting.

[0019] 3. During the blood collection process, the blood collection tube is placed in the receiving groove. After the blood collection tube has been shaken, the limiting device restricts the position of the strip block in the strip groove, allowing the strip block to be removed from the strip groove. Then, the mounting plate can be removed from the mounting block. At this point, the staff can take out the shaken blood collection tube and place a new blood collection tube. The operation is convenient and quick, and has good practicality.

[0020] 4. When placing the blood collection tube into the receiving groove, push the arc-shaped clamps away from each other as the blood collection tube is placed. This makes the operation more convenient. After the blood collection tube is placed into the receiving groove, the arc-shaped clamps move away from the placement hole under the action of the third elastic element, thereby pressing the blood collection tube in the receiving groove firmly and effectively fixing it. This prevents the blood collection tube from falling out of the receiving groove during shaking and improves the overall practicality of the device. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0031] The following is for reference Figures 1 to 7 The present invention will be described in further detail below.

[0032] Reference Figure 1 A blood collection tube storage device includes a base 1, a support column 11 on the base 1, a mounting part 12 at the top of the support column 11, and a rotating disk 13 rotatably mounted on the side wall of the mounting part 12. Figure 1 As shown, there are two rotating disks 13, which are symmetrically distributed on both sides of the mounting part 12.

[0033] like Figure 2 and Figure 3 Each rotating disk 13 has a through mounting hole 2. A mounting shaft 21 is rotatably mounted in the mounting hole 2. A mounting block 22 is fixedly mounted at one end of the mounting shaft 21. A mounting plate 23 is detachably mounted on the mounting block 22. Several receiving grooves 24 are provided on the mounting plate 23. The receiving grooves 24 are used to receive blood collection tubes. A driving member 14 is provided on the mounting part 12. The driving member 14 is used to drive the rotating disk 13 to rotate.

[0034] Reference Figure 3 A reciprocating assembly 3 is provided on the mounting part 12. The reciprocating assembly 3 is used to drive the mounting block 22 to reciprocate. A first elastic element 25 is provided on the rotating disk 13. The first elastic element 25 is used to drive the mounting block 22 to maintain a horizontal state.

[0035] Among them, reference Figure 2 A receiving cavity 26 is provided in the mounting part 12. The driving component 14 is a driving motor, which is fixedly installed in the receiving cavity 26. A transmission shaft 27 is coaxially fixedly installed on the output shaft of the driving motor. A through hole 28 is provided on the side wall of the mounting part 12 through which the transmission shaft 27 passes. The rotating disk 13 is coaxially fixedly installed at the end of the transmission shaft 27.

[0036] As one embodiment of the present invention, refer to Figure 2 The drive unit 14 is a dual-head drive motor, and each end of the drive unit 14 is provided with an output shaft, and each output shaft is connected to the rotating disk 13 for transmission.

[0037] As one embodiment of the present invention, refer to Figure 3 The reciprocating assembly 3 includes a drive ring 31 and a gear 32. The drive ring 31 is sleeved on the transmission shaft 27. One side of the drive ring 31 is fixedly connected to the mounting part 12. The gear 32 is coaxially fixedly disposed at the end of the mounting shaft 21 away from the mounting block 22. A tooth groove 33 is provided on the outer peripheral wall of the drive ring 31. Multiple sets of tooth grooves 33 are evenly provided along the circumference of the drive ring 31. The gear 32 meshes with the tooth groove 33.

[0038] In actual use, the starter drive 14 rotates the rotating disk 13 via the transmission shaft 27. During the rotation of the rotating disk 13, the mounting shaft 21 is driven to deflect around the axis of the transmission shaft 27. Since the gear 32 meshes with the tooth groove 33, the deflection of the mounting shaft 21 drives the gear 32 to rotate, which in turn drives the mounting shaft 21 to rotate. The mounting shaft 21 drives the mounting block 22, which in turn drives the mounting plate 23 to deflect. During this process, the rotation of the mounting shaft 21 compresses the first elastic element 25, causing the first elastic element 25 to store energy. As the mounting shaft 21 continues to move, the gear 32 disengages from the tooth groove 33. At this time, the mounting shaft 21 returns to its initial position under the action of the first elastic element 25. During this process, the shaking of the mounting block 22 causes the shaking of the mounting plate 23 and the blood collection tube in the receiving groove 24, thereby achieving full mixing of blood and anticoagulant.

[0039] Reference Figure 3 A receiving hole 34 is coaxially formed in the mounting hole 2, and the diameter of the receiving hole 34 is larger than the diameter of the mounting hole 2. A mounting ring 35 is coaxially fixed on the mounting shaft 21 and is located in the receiving hole 34. As one embodiment of the present invention, the first elastic element 25 is set as a torsion spring. The first elastic element 25 is located in the receiving hole 34 and is sleeved on the mounting shaft 21. One end of the first elastic element 25 is fixedly connected to the inner wall of the receiving hole 34, and the other end is fixedly connected to the side wall of the mounting ring 35.

[0040] Reference Figure 4 and Figure 5 A strip groove 4 is provided vertically at one end of the mounting block 22 away from the mounting shaft 21. A strip block 41 is slidably disposed in the strip groove 4. The strip block 41 is fixedly connected to the mounting plate 23. A limiting member 42 is provided on the mounting block 22 to limit the position of the strip block 41 in the strip groove 4.

[0041] As one embodiment of the present invention, refer to Figure 5 The limiting member 42 is set as a limiting pin. A connecting hole 43 is provided on the side wall of the mounting block 22. The connecting hole 43 is connected to the strip groove 4. The limiting member 42 slides through the connecting hole 43. A limiting hole 44 is provided on the strip block 41 for the limiting member 42 to be inserted. A second elastic member 45 is provided on the mounting block 22. The second elastic member 45 is used to drive the limiting member 42 to move toward the strip groove 4.

[0042] Reference Figure 5 A locking key 46 is fixedly provided on the limiting member 42 along the axis of the limiting member 42. A locking groove 47 is provided on the side wall of the mounting block 22 for the locking key 46 to slide and connect. The locking groove 47 communicates with the connecting hole 43. A boss 48 is fixedly provided at the end of the limiting member 42 away from the mounting block 22. As one embodiment of the present invention, see reference. Figure 5 The second elastic element 45 is configured as a tension spring. The second elastic element 45 is sleeved on the limiting element 42. One end of the second elastic element 45 is fixedly connected to the boss 48, and the other end is fixedly connected to the side wall of the mounting block 22.

[0043] In actual use, when it is necessary to disassemble or assemble the mounting plate 23, the blood collection tubes in the receiving groove 24 of the mounting plate 23 are usually removed or a newly collected blood collection tube is placed. At this time, the limiting member 42 is pulled to disengage the end of the limiting member 42 from the limiting hole 44. During this process, the locking key 46 is disengaged from the locking groove 47. When the locking key 46 is completely disengaged from the locking groove 47, the end of the limiting member 42 is completely disengaged from the limiting hole 44. At this time, the limiting member 42 is rotated and released. Under the action of the second elastic member 45, the limiting member 42 moves towards the strip groove 4, thereby causing the end of the locking key 46 to abut against the side wall of the mounting block 22. At this time, the position of the limiting member 42 in the connecting hole 43 can be limited, preventing the limiting member 42 from being reinserted into the limiting hole 44. Then, the operator can pull the strip block 41 upward to disengage from the strip groove 4, making the operation more convenient and faster.

[0044] Reference Figure 4 and Figure 5The bottom of the strip block 41 is provided with a slope 5, and a ball bearing 51 is embedded at the end of the limiting member 42. The ball bearing 51 is used to roll and contact the slope 5. A pull ring 52 is provided at the end of the boss 48 away from the limiting member 42. The pull ring 52 is used to pull the limiting member 42.

[0045] When the strip block 41 is inserted into the strip groove 4, the ball 51 at the end of the limiting member 42 first contacts the inclined surface 5. Under the push of the inclined surface 5, the limiting member 42 moves away from the strip groove 4, which makes it easier for the staff to put the strip block 41 into the strip groove 4.

[0046] Meanwhile, during this process, the friction between the inclined surface 5 and the end of the limiting member 42 is effectively reduced by the ball bearing 51, which further facilitates the staff to put the strip block 41 into the strip groove 4, making the operation more convenient.

[0047] Reference Figure 6 and Figure 7 The receiving groove 24 has an opening at the top. A placement hole 6 is provided on the inner wall of the receiving groove 24 in a horizontal direction. A placement block 61 is slidably disposed in the placement hole 6. An arc-shaped clamp 62 is fixedly disposed at the end of the placement block 61 away from the placement hole 6. The concave surface of the arc-shaped clamp 62 is used to slide and connect with the outer wall of the blood collection tube. A third elastic member 63 is provided in the placement hole 6. The third elastic member 63 is used to drive the placement block 61 to move in a direction away from the placement hole 6. An anti-detachment part 64 is provided on the placement block 61. The anti-detachment part 64 is used to prevent the placement block 61 from detaching from the placement hole 6.

[0048] Reference Figure 7 In one embodiment of the present invention, the anti-detachment part 64 is configured as an anti-detachment ring, which is fixedly installed at the end of the placement block 61 away from the arc-shaped clamp 62. The diameter of the anti-detachment ring is larger than the diameter of the placement block 61. An abutment ring 65 is fixedly provided at the opening of the placement hole 6. The abutment ring 65 is used to abut against the side wall of the anti-detachment ring. The inner diameter of the abutment ring 65 is adapted to the diameter of the placement block 61.

[0049] As one embodiment of the present invention, refer to Figure 7 The third elastic element 63 is configured as a compression spring, with one end of the compression spring abutting against the anti-disengagement device and the other end abutting against the inner wall of the placement hole 6.

[0050] As one embodiment of the present invention, an anti-slip pad 7 is fixedly provided on the concave surface of the arc-shaped clamp 62. The anti-slip pad 7 can improve the friction between the arc-shaped clamp 62 and the blood collection tube to a certain extent, which can effectively prevent the blood collection tube from falling off during the shaking process, and further improve the overall practicality of the device.

[0051] As another embodiment of the present invention, refer to Figure 8A mounting bracket 8 is provided on the base 1. The mounting bracket 8 has a storage hole 81. The mounting bracket 8 is located on one side of the support column 11. There are two mounting brackets 8, which are respectively located on both sides of the support column 11. Each mounting bracket 8 has a storage hole 81. The storage hole 81 is used to store blood collection tubes. One mounting bracket 8 is used to hold blood collection tubes that have been used for blood collection, and the other mounting bracket 8 is used to hold empty blood collection tubes. A groove 82 is provided on the top of the base 1 corresponding to each storage hole 81. In actual use, the groove 82 is used to hold the bottom of the blood collection tube to prevent the blood collection tube from shaking on the mounting bracket 8.

[0052] The implementation principle of the blood collection tube storage device proposed in the present embodiment is as follows:

[0053] After blood collection, the blood collection tube is placed in the receiving groove 24. Then, the reciprocating assembly 3 drives the mounting block 22 to reciprocate. During the reciprocating deflection of the mounting block 22, the mounting plate 23 is deflected. As the mounting plate 23 deflects, the blood collection tube in the receiving groove 24 shakes, which allows the blood in the blood collection tube to mix fully with the anticoagulant, effectively preventing clotting. The drive motor drives the transmission shaft 27 to rotate. As the transmission shaft 27 rotates, the rotating disk 13 rotates. As the rotating disk 13 rotates, the mounting shaft 21 rotates. As the mounting shaft 21 rotates, the gear 32 rotates on the drive ring 31. Since the gear 32 meshes with the tooth groove 33, the rotating shaft rotates. As the rotating shaft rotates, the mounting block 22 and the mounting plate 23 deflect. When the gear 32 disengages from the tooth groove 33, the mounting shaft 21 deflects back under the action of the first elastic element 25, which causes the blood collection tube to shake, effectively improving the mixing of blood and anticoagulant and preventing clotting.

[0054] The above are merely preferred embodiments of the present invention and are not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
