Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an integrated centrifugal mixing and processing device for body fluids in the laboratory. Background Technology

[0002] In the daily work of hospital laboratories, the testing of bodily fluids (such as urine, pleural effusion, peritoneal fluid, and cerebrospinal fluid) is a common task. After extraction, these bodily fluid samples require a series of pretreatment steps, such as centrifugation and mixing, before they can be observed and analyzed. Pretreatment steps are crucial for improving the accuracy and efficiency of testing.

[0003] Chinese patent CN214864440U discloses an integrated centrifugation and mixing device for body fluids in a laboratory. The device includes a base with at least two support rods evenly distributed around its top periphery. An adjustment mechanism is fixed to the upper end of each support rod. Two threaded rods extend from the base into the adjustment mechanism and pass through a lifting plate. A first motor is mounted on the top of the lifting plate, its shaft passing downwards through the plate. A transfer cup fixing plate is fixed to the first motor shaft. A cup holder groove is also provided on the top surface of the base, containing a cup holder comprising an external fixed seat and an internal movable seat. An elliptical ring plate is located at the bottom of the cup holder. A second motor is located at the bottom of the base, with a cam on its shaft extending into the elliptical ring plate. This utility model patent, employing the above structure, solves both centrifugation and mixing pretreatment needs for body fluid samples with a single device, achieving a more convenient and efficient body fluid pretreatment process.

[0004] When using the aforementioned integrated centrifugation and mixing device for body fluids in the laboratory, the test tubes still need to be manually removed after centrifugation, and the supernatant inside the test tubes needs to be cleaned. This not only increases the workload of medical staff, but also affects subsequent mixing operations.

[0005] To address these issues, this invention provides an integrated centrifugal mixing and processing device for body fluids used in clinical laboratories. Utility Model Content

[0014] Beneficial effects

[0015] This invention provides an integrated centrifugal mixing and processing device for body fluids in the laboratory. Compared with the prior art, it has the following advantages:

[0016] (1) The integrated centrifugation and mixing device for body fluids in the laboratory has a clearing component that automatically cleans the supernatant in the test tube after centrifugation. This not only improves the centrifugation and mixing efficiency of the test tube, but also avoids frequent contact between medical staff and test tubes, thus preventing cross-infection. At the same time, the clamping claw can clamp the stopper in the test tube, thereby opening the test tube and facilitating the aspiration of the supernatant inside the test tube. This achieves the effect of automatically cleaning the supernatant in the test tube and improves the processing efficiency.

[0017] (2) The integrated centrifugation and mixing device for body fluids in the laboratory uses a rotating component to adjust the test tubes in the test tube rack at different angles, thereby improving the centrifugation efficiency and optimizing the separation efficiency of the liquid inside the test tubes. This achieves the effect of tilting the test tubes at different angles. At the same time, tilting the test tube rack makes it easier to install and remove the test tubes. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1:

[0025] Please see Figure 1-4 The laboratory uses an integrated centrifugal mixing and processing device for body fluids, which includes a testing device body 1, a control console 4 fixed to the side of the testing device body 1, a clearing component 2 fixed inside the testing device body 1, and a rotating component 3 fixed to the bottom of the clearing component 2.

[0026] The clear liquid assembly 2 includes a cylinder 21, a support plate 22 fixed to the top of the cylinder 21, a hydraulic rod 23 fixed to the bottom of the support plate 22, a rotating groove 24 opened at the bottom of the hydraulic rod 23, a rotating block 25 rotatably connected in the rotating groove 24, a suction pipe 26 fixed to the side of the rotating block 25, a suction port 27 opened at the other end of the suction pipe 26, a connecting pipe 28 sealed to the top of the suction pipe 26, and a liquid accumulation tank 29 sealed to the other end of the connecting pipe 28.

[0027] The rotating block 25 is L-shaped. A motor 210 is fixed to the bottom side of the rotating block 25. A drive gear 211 is fixed to the output end of the motor 210. Driven gears 212 are meshed on both sides of the drive gear 211. A clamping claw 213 is fixed to the outside of the driven gear 212. The motor 210 is electrically connected to the control console 4, which can drive the clamping claw 213 to clamp and remove the test tube stopper on the test tube, thereby enabling automatic cleaning of the test tube after centrifugation.

[0028] The gripper 213 is rotatably connected to the rotating block 25. The rotating block 25 is electrically connected to the control console 4, so that the rotating block 25 can rotate in the rotating slot 24 to achieve the effect of automatic conversion.

[0029] The number of hydraulic rods 23 is equal to the number of test tubes, so that the rotating block 25 at the bottom of each hydraulic rod 23 corresponds to one test tube sample. The hydraulic rods 23 and the clamping claws 213 have all been disinfected to prevent cross-infection.

[0030] In this embodiment, after the testing device body 1 centrifuges the test tube, the control console 4 controls the rotating block 25 to rotate in the rotating groove 24, causing the clamping claw 213 to rotate above the test tube. Then, the control motor 210 drives the driving gear 211 and the driven gear 212 to mesh, so that the clamping claw 213 can clamp the test tube stopper on the test tube. Then, the hydraulic rod 23 moves upward to pull out the test tube stopper. Then, the control console 4 controls the rotating block 25 to rotate, causing the suction tube 26 to rotate to the top of the test tube. Then, the hydraulic rod 23 moves downward to allow the suction tube 26 to enter the test tube opening. Then, the suction pump in the liquid collection tank 29 suctions the upper clear liquid in the test tube. Then, the suction liquid flows through the suction port 27 into the connecting pipe 28 and into the liquid collection tank 29 for storage. Then, the test tube stopper is put into the test tube, which facilitates the subsequent mixing operation of the test tube.

[0031] Example 2:

[0032] Please see Figure 1-4This embodiment provides a technical solution based on embodiment one: the rotating component 3 includes an adjusting ring 31, a flipping groove 32 is provided on the outer side of the adjusting ring 31, a rotating column 33 is rotatably connected in the flipping groove 32, a connecting shaft 34 is fixed on the rotating column 33, and a test tube rack 35 is fixed at the other end of the connecting shaft 34.

[0033] The test tube rack 35 has test tube slots, and there is a gap between the test tube rack 35 and the adjusting ring 31. The rotating column 33 is electrically connected to the control console 4, so that the test tube rack 35 will not get stuck when it is flipped and the angle is adjusted.

[0034] In this embodiment, the rotating column 33 can be controlled to rotate in the flipping groove 32 by the control console 4 according to the actual usage, so that the test tube rack 35 can be flipped up and down. When centrifuging the test tubes, the test tube rack 35 can be flipped to adjust the test tubes to a suitable angle, thereby improving the separation efficiency of the liquid in the test tubes and achieving the effect of improving the centrifugation efficiency.

[0035] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
