Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more specifically to an anti-coagulation blood collection tube oscillator. Background Art

[0002] A blood collection tube is a medical device used to collect blood. Generally, an anticoagulant tube is connected to the bottom of the blood collection tube, which contains an anticoagulant. The anticoagulant tube used for blood drawing is generally divided into different colors according to its purpose, such as blue, green, light green, etc. When one end of the blood collection needle is inserted into the human vein, the other end is inserted into the rubber stopper of the vacuum blood collection tube. Under the action of vacuum negative pressure, the human venous blood is drawn into the anticoagulant tube through the blood collection needle, and then the anticoagulant is mixed with the blood by shaking to prevent the blood from clotting before being sent to the next step of testing.

[0003] After collecting blood, medical staff need to manually shake the existing anticoagulant tube to mix the internal anticoagulant with the blood. This greatly increases the workload of medical staff during use, which can cause wrist pain over time, thereby increasing the risk of dropping the tube and affecting work efficiency. In addition, the tube can easily slip out of the hand during shaking, causing the tube to fall to the ground and leak blood inside, thereby causing environmental pollution and even spreading viruses in the blood to the environment.

[0046] like Figures 1 to 9 As shown, an embodiment of the present invention provides an anti-coagulation blood collection tube oscillator, including a base 1, a fixing frame 2 is fixedly connected to the corners on both sides of the upper surface of the base 1, a mounting groove 3 is opened in the middle of both sides of the upper surface of the base 1, and an oscillation component 4 for oscillating the blood collection tube is slidably connected inside the mounting groove 3.

[0047] like Figure 2-Figure 5 As shown, the oscillation component 4 includes a vertical plate 44 sliding inside the mounting slot 3 and a first drive motor 41 fixed on the lower surface of the fixed frame 2, the output end of the first drive motor 41 is fixedly connected to a disc 42, the lower surface of the disc 42 is fixedly connected to a drive shaft 43, the upper surface of the vertical plate 44 is connected to a top plate 415, the upper surface of the top plate 415 is fixedly connected to a swing plate 47, a circular groove 49 is provided on the upper surface of the swing plate 47, a rotating plate 410 is rotatably connected inside the circular groove 49, two jacks 411 are provided inside the rotating plate 410, rectangular frames 48 are fixedly connected to both sides of the swing plate 47, two fixed rods 412 are fixedly connected to the bottom of the rotating plate 410, the outer surfaces of the two fixed rods 412 are sleeved with a second sleeve 413, and the bottom of the second sleeve 413 is fixedly connected to a placement plate 414.

[0048] A vertical swing component 45 is provided on one side of the vertical plate 44, a conversion component 46 is connected to the middle of the lower surface of the swing plate 47, the bottom of the driving shaft 43 extends to the inside of the rectangular frame 48 and slidably adapts, a collecting groove is provided at the edge of the upper surface of the swing plate 47, the rotating plate 410 is connected to the circular groove 49 through a bearing, a blood collection tube groove corresponding to the socket 411 is provided on the upper surface of the placement plate 414, and an adaptability component 5 is fixedly connected between the two second sleeves 413.

[0049] The medical worker places the collected blood sample in a collection tube containing an anticoagulant. To prevent the blood in the collection tube from clotting, the collection tube needs to be shaken continuously to fully blend the anticoagulant and the blood. Manual shaking is inefficient, so a tool is needed to shake the blood collection tube. The collected blood collection tube is inserted into the inside of the jack 411, and the bottom of the blood collection tube is inserted into the inside of the blood collection tube slot. At this time, the first drive motor 41 is started to work, driving the disc 42 to rotate, and the disc 42 drives the drive shaft 43 to perform a circular motion. Inside the rectangular frame 48, the rectangular frame 48 drives the swing plate 47 to swing back and forth continuously, and the top plate 415 drives the vertical plate 44 to swing inside the mounting slide groove 3, and the swing plate 47 drives the blood collection tube inside it to shake and swing, so that the blood and anticoagulant inside the blood collection tube are integrated, avoiding hand soreness caused by manually shaking the collection tube, preventing the blood collection tube from accidentally falling out of the hand and causing blood leakage to pollute the surrounding environment. Other collection operations can be performed while the blood collection tube is shaking, greatly improving the efficiency of the entire blood collection.

[0050] like Figure 2 , Figure 4 and Figure 5 As shown, the vertical swing assembly 45 includes a second drive motor 451 fixed to one side of the vertical plate 44, a top block 454 fixed to the bottom of the top plate 415, and a receiving groove 456 opened inside the vertical plate 44, the interior of the receiving groove 456 is slidably connected to the telescopic plate 455, the output end of the second drive motor 451 is fixedly connected to the third worm gear 452, and the outer surface of the third worm gear 452 is fixedly connected to cams 453 on both sides.

[0051] The top block 454 is located at the top of the cam 453 , the bottom of the top block 454 contacts the surface of the cam 453 , the top of the telescopic plate 455 is fixedly connected to the bottom of the top plate 415 , and the top plate 415 is located above the vertical plate 44 and is not fixedly connected.

[0052] When the blood collection tube is swung back and forth, there will be a problem that the anticoagulant content in the upper and lower parts of the blood is different, resulting in different anticoagulant effects. Therefore, when the first drive motor 41 is turned on to work, the second drive motor 451 can be turned on to work at the same time, and the second drive motor 451 drives the third worm 452 to rotate, and the third worm 452 drives the two cams 453 to rotate at the same time. When the cam 453 rotates, it will push the top block 454 upward, and drive the top plate 415 to slide upward inside the storage groove 456 through the telescopic plate 455. The top plate 415 drives the swing plate 47 upward as a whole, so that the blood collection tube can swing up and down while swinging back and forth, so that the blood and anticoagulant inside the blood collection tube are fused. By changing the rotation speed of the second drive motor 451 and the first drive motor 41, the swinging speed of the swing plate 47 can be changed, thereby avoiding hemolysis of the blood, and the rectangular frame 48 moves up and down on the outside of the drive shaft 43 at the same time.

[0053] like Figure 4 and Figure 6 As shown, the conversion assembly 46 includes a first worm gear 461 rotating in the middle of the lower surface of the swing plate 47, a support plate 468 fixed on one side of the vertical plate 44, and a second worm gear 463 rotating on both sides of the lower surface of the swing plate 47, the bottom of the second worm gear 463 is fixedly connected to a rectangular rod 464, the interior of the support plate 468 is rotatably connected to a first sleeve 465, the outer surface of the first sleeve 465 is fixedly connected to a third worm gear 466, the outer surface of the first worm gear 461 is fixedly connected to second worm gears 462 on both sides of the outer surface, and the outer surfaces of the two fixed rods 412 are fixedly connected to the first worm gear 467.

[0054] The first worm wheel 467 is at the same horizontal height as the first worm 461, the first worm wheel 467 and the first worm 461 are meshed with each other, the second worm 463 and the second worm wheel 462 are meshed with each other, the bottom of the rectangular rod 464 extends into the first sleeve 465, the rectangular rod 464 and the first sleeve 465 slide with each other, and the third worm wheel 466 and the third worm 452 are meshed with each other.

[0055] While the third worm 452 is rotating, the third worm 452 will synchronously drive the third worm wheel 466 meshing with it to rotate, and the third worm wheel 466 will drive the first sleeve 465 to rotate. The first sleeve 465 drives the second worm 463 to rotate through the rectangular rod 464. The second worm 463 drives the first worm 461 to rotate through the second worm wheel 462 meshing with it. The first worm 461 drives the six first worm wheels 467 to rotate synchronously, and drives the rotating plate 410 to rotate through the two fixed rods 412. The up and down movement of the swing plate 47 will drive the rectangular rod 464 to slide inside the first sleeve 465 through the second worm 463, which will not hinder the up and down movement of the swing plate 47, but drive the blood collection tube to perform circular motion. In this way, the efficiency of the fusion of anticoagulants and blood can be further improved, the time of blood oscillation and fusion can be greatly reduced, and multiple batches of blood oscillation operations can be performed in a short time.

[0056] like Figure 7 and Figure 8 As shown, the adaptive component 5 includes a third sleeve 51 fixed between the two second sleeves 413, a rack groove 55 opened on one side of the fixed rod 412, and two fixed components 52 fixed on the upper surface of the placement plate 414, one side of the inner surface of the rack groove 55 is fixedly connected to the first rack 57, both sides of the third sleeve 51 are slidably connected to the sliding rods 54, the side where the two sliding rods 54 are close to each other is fixedly connected to the extrusion plate 53, the side where the two extrusion plates 53 are close to each other is fixedly connected to the second spring 56, and the side where the two sliding rods 54 are away from each other is fixedly connected to the second rack 58.

[0057] One side of the slide rod 54 passes through the second sleeve 413 and extends to the inside of the rack groove 55. The second rack 58 is meshed with the first rack 57. The bottom of the extrusion plate 53 extends to the inside of the third sleeve 51. A through groove is provided on the outer surface of the third sleeve 51. The extrusion plates 53 pass through the through groove and slide relative to each other.

[0058] Due to the different specifications of existing blood collection tubes, the blood collection tube oscillator cannot be well equipped with blood collection tubes of different specifications, which will cause the blood collection tube to be unable to adapt to the oscillator. When a blood collection tube that is too short is placed inside the socket 411, the height of the blood collection tube will be lower than the height of the rotating plate 410, making it impossible for the blood collection tube to stand stably inside the blood collection tube slot on the placement plate 414 and easy to fall when shaken.

[0059] Therefore, by adjusting the distance between the placement plate 414 and the rotating plate 410 to adapt to blood collection tubes of different lengths, by pressing the two pressing plates 53, the two sliding rods 54 and the second rack 58 are driven to approach each other. The second rack 58 and the first rack 57 are separated from each other, the fixed state between the fixed rod 412 and the second sleeve 413 is released, the placement plate 414 is lifted upward, and the second sleeve 413 slides on the outside of the fixed rod 412. When adjusted to the appropriate position, the pressing plate 53 is released. Under the action of the second spring 56, the two second racks 58 are quickly reset and meshed with the first rack 57 again, the fixed rod 412 and the second sleeve 413 are meshed and fixed, and then the blood collection tube is placed inside the jack 411, so that the top of the blood collection tube is higher than the rotating plate 410, enabling the blood collection tube to perform an oscillation operation, making the oscillator adaptable to blood collection tubes of different specifications and lengths, with high adaptability and matching degree.

[0060] As Fig. 9 shown, the fixing assembly 52 includes two U-shaped frames 521 fixed at the edge of the upper surface of the placement plate 414 and two pull rods 525 slidably connected inside the placement plate 414. The lower surface of the U-shaped frame 521 is fixedly connected with a pressing column 522. The bottom of the two pull rods 525 is fixedly connected with a connecting plate 526. The upper surface of the connecting plate 526 is fixedly connected with a first spring 527. The top of the pull rod 525 is slidably connected with a connecting slide rail 524, and the top of the connecting slide rail 524 is fixedly connected with a trapezoidal block 523.

[0061] The top of the first spring 527 is fixed to the lower surface of the placement plate 414. The trapezoidal block 523 is located inside the U-shaped frame 521. The bottom of the pressing column 522 contacts the hypotenuse of the trapezoidal block 523. One side of the trapezoidal block 523 is fixedly connected with an anti-slip pad.

[0062] Although the oscillator can adapt to blood collection tubes of different specifications, there is a lack of limitation, and the blood collection tube will continuously shake inside the jack 411 and inside the blood collection tube slot, constantly hitting the rotating plate 410. The continuous impact will damage the blood collection tube, easily cause blood leakage, and reduce the safety of the oscillator. Therefore, when inserting the blood collection tube into the inside of the blood collection tube slot, pull down the two pull rods 525 to move downward, driving the trapezoidal block 523 to move downward. When the blood collection tube enters the slot, release the pull rod 525, and the first spring 527 contracts, driving the pull rod 525 to move upward, pushing the two trapezoidal blocks 523 upward to contact the bottom of the pressing column 522. When the inclined surface of the trapezoidal block 523 contacts the pressing column 522, the two trapezoidal blocks 523 move upward and approach each other at the same time. The two approaching trapezoidal blocks 523 will stably clamp the side wall of the blood collection tube, ensuring stable support for the blood collection tube inside the jack 411, avoiding damage to the blood collection tube caused by continuous impact between the blood collection tube and the swing plate 47, and improving the safety of the oscillator.

[0063] The workflow of the present invention is as follows:

[0064] First, the first drive motor 41 works, and through the cooperation of the drive shaft 43 and the rectangular frame 48, it can drive the swing plate 47 and the blood collection tube to swing back and forth, and can fuse the blood and anticoagulant to replace manual shaking to improve efficiency. Through the cooperation of the various parts of the vertical swing assembly 45, the blood collection tube can be driven to move up and down, and the anticoagulant content in the blood in the upper and lower parts of the blood collection tube can be ensured to be consistent, ensuring the full fusion of the anticoagulant and blood. With the cooperation of the various parts of the conversion assembly 46, the fusion rate of the anticoagulant and blood can be accelerated, and multiple batches of blood collection tubes can be shaken and oscillated at the same time.

[0065] Then, with the cooperation of the first rack 57 and the second rack 58, the height of the placement plate 414 can be adjusted so that blood collection tubes of different lengths can be used in the oscillator. While clamping the blood collection tubes, the two trapezoidal blocks 523 move upward under the action of the first spring 527, and the inclined surface of the trapezoidal block 523 contacts the bottom of the squeezing column 522. The two trapezoidal blocks 523 approach each other to clamp and fix the blood collection tube to avoid collision between the blood collection tube and the swing plate 47.

[0066] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details.
