Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a processing device for bone marrow collection. Background Art

[0002] The bone marrow exists in the cancellous bone cavities and the medullary cavities of long bones. It is composed of various types of cells and reticular connective tissue. It is a soft, blood-rich tissue. Bone marrow puncture is a commonly used diagnostic and treatment method in hematology. Through bone marrow puncture, the various components in the bone marrow and the morphological and composition changes of cells can be seen, so as to diagnose the specific cause of the disease. The operation is to insert the puncture needle into the patient's bone marrow, and then extract the bone marrow. The extracted bone marrow fluid is placed in a collection tube to ensure that the bone marrow fluid and anticoagulant are fully mixed, so as to check the patient's physical health.

[0003] During the process of collecting bone marrow fluid, anticoagulants are usually added to the collection tube in advance. Currently, most of them are added manually by medical staff, and the addition ratio varies according to the type and purpose of the anticoagulant. However, during the manual addition of anticoagulants, the concentration and uniformity of the anticoagulant are difficult to guarantee, which may lead to unstable anticoagulant effect, thereby affecting the quality of the collected samples. In addition, the sample may encounter bumps or vibrations during the transfer process, causing the collection tube to shake violently, causing cell rupture or sample deterioration, and it will be affected by the external temperature and the bone marrow fluid itself during the transfer process, resulting in sedimentation, which to a certain extent reduces the quality of the sample and reduces the utilization rate.

[0004] Based on the above situation, the present invention proposes a bone marrow collection processing device that can quantitatively add materials and improve sample quality. Summary of the invention

DETAILED DESCRIPTION

[0036] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0037] Embodiment 1: A bone marrow collection processing device, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, A, B, C and D respectively refer to the front, right, left and back sides of the device. The bone marrow collection processing device includes a shell 1, a 60-degree opening is opened on the front side of the shell 1, a non-slip silicone pad is provided at the bottom of the shell 1, a cover plate 2 for controlling the opening and closing of the opening is rotatably connected to the opening of the shell 1, a handle 21 is rotatably connected between the left and right sides of the top of the shell 1, a servo motor 3 is installed in the shell 1, and a rotating plate 4 is fixedly connected to the output shaft on the upper side of the servo motor 3. The rotating plate 4 is evenly fixedly connected with a plurality of rubber strips 41 along the circumferential direction. In the present embodiment, twelve rubber strips 41 are provided in total, each of which is fixedly connected to two symmetrically distributed placement racks 42, and collection tubes 43 are placed in the placement racks 42.

[0038] The bone marrow collection and processing device also includes a quantitative mechanism, which is arranged on the shell 1. The quantitative mechanism includes a container 51, which is fixedly connected to the right side of the top of the shell 1. A fluid replenishment tank 511 is arranged on the right side of the top of the shell 1. A conduit 512 is connected between the front wall of the fluid replenishment tank 511 and the front wall of the container 51. The center line of the container 51 is 30 degrees apart from the center line of the cover plate 2. The container 51 is used to hold an anticoagulant. The fluid replenishment tank 511 also contains an anticoagulant for replenishing the anticoagulant into the container 51. The front and rear sides of the bottom wall of the container 51 are fixedly connected with a soft discharge nozzle 52. The front and rear sides of the container 51 are slidably connected with a first sliding rod 531. The top surface of the container 51 is open. The top of the first sliding rod 531 is connected to the top. A pressure plate 53 is slidably connected to the inner wall of the container 51, and the pressure plate 53 seals the top surface of the container 51. A first spring 55 is connected between the pressure plate 53 and the container 51, and the first spring 55 is wound around an adjacent first sliding rod 531. The fluid replenishment tank 511 is provided with an injection port for injecting anticoagulant into the fluid replenishment tank 511, and a plug 54 is provided on the injection port. A quantitative adjustment rod 56 is threadedly connected to the front side of the pressure plate 53, and a scale is marked on the quantitative adjustment rod 56. The scale indicates the amount of anticoagulant dripped into the collection tube 43 at one time. The larger the scale, the more anticoagulant is dripped. The staff can screw the quantitative adjustment rod 56 to a specified position according to the type and purpose of the anticoagulant to ensure the added concentration of the anticoagulant.

[0039] Initially, the anticoagulant has been loaded in the container 51, and the collection tube 43 with the lid unscrewed has been placed in the placement rack 42 in advance. When using the device, the staff first flips the cover plate 2 upward to open it, and then sets the position of the quantitative adjustment rod 56 as needed, and adjusts the quantitative adjustment rod 56 up and down to a suitable scale. When the position of the quantitative adjustment rod 56 is set, the staff can press the pressing plate 53 downward, thereby driving the quantitative adjustment rod 56 and the first sliding rod 531 to move downward together, and the first spring 55 will be deformed. The pressure in the container 51 increases, causing the anticoagulant to drip from the soft discharge nozzle 52 into the collection tube 43 directly below, completing the addition of the anticoagulant. When the quantitative adjustment rod 56 moves downward to contact the top of the container 51, the container 51 will resist the quantitative adjustment rod 56, resulting in the distance of the pressing plate 53 moving downward this time being limited, so that the amount of anticoagulant dripping is accurately controlled, and then the pressing plate 53 can be released. Under the elastic action of the first spring 55, the first spring 55 will drive the pressing plate 53 and the quantitative adjustment rod 56 to move upward and reset. While the anticoagulant in the container 51 is discharged, the liquid replenishment tank 511 will replenish the anticoagulant into the container 51 to keep the container 51 always full of anticoagulant. Then start the servo motor 3, the output shaft of the servo motor 3 will drive the rotating plate 4 to rotate 30 degrees clockwise and pause for a certain period of time, thereby driving the rubber strip 41, the placement rack 42 and the collection tube 43 with added anticoagulant to rotate to the opening of the shell 1. At this time, the staff can press the pressing plate 53 again and then release it to add anticoagulant to a new group of collection tubes 43. Secondly, take out the collection tube 43 with added anticoagulant from the placement rack 42 for bone marrow collection. After the collection is completed, shake the collection tube 43 to mix the bone marrow and anticoagulant, and then put it back to its original position. Similarly, when the collection is completed, turn off the servo motor 3, flip the cover plate 2 downward and close it, and then hold the handle 21 to lift the shell 1 containing the sample to the detection room to complete this work. By setting the position of the quantitative adjustment rod 56, the staff can accurately control the amount of anticoagulant dripping according to needs, so that the anticoagulant effect is more stable, thereby improving the quality of the collected samples.

[0040] Embodiment 2: Based on embodiment 1, Figure 2 , Figure 8 , Fig. 9 , Fig.10 and Fig.11As shown, a stabilizing mechanism is also included, which is arranged in the outer shell 1. The stabilizing mechanism includes a contact plate 61, which is fixedly connected to the inner side of the cover plate 2. A limiting frame 611 is slidably connected to the rotating plate 4. A guide rail 62 is fixedly connected to the inner bottom wall of the outer shell 1. A rotating frame 63 is rotatably connected in the guide rail 62. The rotating frame 63 is fixedly connected to the rotating plate 4. The rotating frame 63 is evenly slidably connected to twelve sliding blocks 64 along the circumferential direction. The sliding block 64 can slide up and down on the rotating frame 63. The sliding block 64 is located directly below the placement frame 42. Elastic ropes 65 are connected between the sliding block 64 and the adjacent placement frame 42. The limiting frame 611 is squeezed and fitted with the sliding block 64.

[0041] Initially, the contact plate 61 is pressed on the limit frame 611, and the limit frame 611 is pressed on the sliding block 64, so that the elastic rope 65 is in a taut state. Under the pulling force of the elastic rope 65, the rubber strip 41 is pulled downward. When the cover 2 is flipped upward to open, the cover 2 will drive the contact plate 61 to move upward, and the contact plate 61 is no longer pressed on the limit frame 611. Under the elastic action of the elastic rope 65 and the rubber strip 41, the sliding block 64 will drive the limit frame 611 to move upward together. Similarly, when the cover 2 is flipped downward to close, the contact plate 61 will press the limit frame 611 downward again, thereby driving the sliding block 64 to move downward, and the elastic rope 65 will resume the taut state. The elastic rope 65 can prevent the collection tube 43 in the placement rack 42 from being shaken violently during the transfer process, thereby reducing the probability of cell rupture or sample deterioration.

[0042] like Figure 2 , Fig.12 and Fig.13 As shown, the bone marrow collection and processing device also includes an opening mechanism, which is arranged on the rotating plate 4. The opening mechanism includes contact rods 71. The number of contact rods 71 ​​is twelve. The contact rods 71 ​​are evenly fixed to the rotating plate 4 along the circumferential direction. The bottom of the first sliding rod 531 on the front side is fixed with a connecting frame 72, and a bolt 74 is threadedly connected to the connecting frame 72. A rubber bevel block 73 is fixed to the connecting frame 72 through the bolt 74. When the contact rod 71 rotates with the rotating plate 4 to contact the inclined surface at the top of the rubber bevel block 73, the contact rod 71 and the rubber bevel block 73 are squeezed and matched.

[0043] When the plate 4 is turned clockwise Fig.12When the rotating contact rod 71 rotates clockwise from the perspective shown in the figure, it will drive the contact rod 71 to rotate together. When the rotating contact rod 71 contacts the rubber bevel block 73, the contact rod 71 will press the rubber bevel block 73 downward, thereby driving the connecting frame 72, the first sliding rod 531 and the pressure plate 53 to move downward together, and the first spring 55 is deformed. When the rotating contact rod 71 separates from the rubber bevel block 73, under the elastic action of the first spring 55, the first sliding rod 531 will drive the pressure plate 53, the connecting frame 72 and the rubber bevel block 73 to move upward and reset. By utilizing the extrusion cooperation between the contact rod 71 and the rubber bevel block 73, automatic addition of anticoagulant is realized, and there is no need for staff to manually press to add, thereby improving work efficiency. It should be noted that the height of the rubber bevel 73 must be greater than the maximum distance that the quantitative adjustment rod 56 can descend. When the contact rod 71 is squeezed by the rubber bevel 73, if the distance that the quantitative adjustment rod 56 descends is less than the height of the rubber bevel 73, the contact rod 71 will deform the rubber bevel 73. When the contact rod 71 and the rubber bevel 73 are separated, the rubber bevel 31 will return to its original state.

[0044] like Figure 2 , Fig.14 and Fig.15 As shown, the bone marrow collection and processing device also includes a swing mechanism, which is arranged on the placement rack 42. The lower part of the placement rack 42 located on the inner side is fixedly connected with a contact column 82. There are twelve contact columns 82 in total. A plurality of fixed rods 81 are fixedly connected to the outer shell 1. In this embodiment, a total of three fixed rods 81 are provided. The contact column 82 will contact the three fixed rods 81 in turn as the placement rack 42 rotates. A telescopic component is provided on the placement rack 42.

[0045] like Fig.14 and Fig.15 As shown, the telescopic assembly includes a second sliding rod 83, two symmetrically distributed second sliding rods 83 are fixedly connected to each outer placement rack 42, two symmetrically distributed fixed sleeves 831 are fixedly connected to each inner placement rack 42, a second spring 84 is connected between the adjacent second sliding rods 83 and fixed sleeves 831, and the second sliding rod 83 and the adjacent fixed sleeves 831 are both slidably connected.

[0046] When the placement rack 42 rotates, it will drive the contact column 82 to rotate together. When the rotating contact column 82 contacts the fixed rod 81, the fixed rod 81 will press against the contact column 82 to deflect the inner placement rack 42 outward, thereby causing the fixed sleeve 831 to move outward, the second spring 84 is compressed, and the rubber strip 41 will deform appropriately. When the rotating contact column 82 separates from the fixed rod 81, under the elastic action of the second spring 84 and the rubber strip 41, the fixed sleeve 831 will drive the inner placement rack 42 to move inward and reset. As the contact column 82 contacts and separates from several fixed rods 81 in turn, the collection tube 43 in the placement rack 42 vibrates. The cooperation between the contact column 82 and the fixed rod 81 allows the collection tube 43 to vibrate, thereby automatically mixing the bone marrow and the anticoagulant without the need for manual shaking by the staff, thereby reducing labor costs.

[0047] like Figure 1 , Figure 2 and Fig.16 As shown, the bone marrow collection and processing device further includes a placement mechanism, which is disposed on the housing 1 . The placement mechanism includes a fixing frame 91 , which is fixedly connected to the top of the housing 1 .

[0048] Before placing the collection tube 43 in the placement rack 42 , the cover on the collection tube 43 needs to be removed first. When the staff needs to place the cover of the collection tube 43 , the staff can put the cover or other related scattered supplies into the fixing frame 91 .

[0049] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, all equivalent changes made to the contents described in the claims of the present invention should be included in the scope of the claims of the present invention.
