Description

Technical Field

[0001] This invention relates to the field of medical testing equipment technology, and in particular to a medical sample analysis device. Background Technology

[0002] Medical sample analysis is an indispensable part of modern medical diagnosis. Through precise analysis of various biological samples such as blood, urine, tissue fluid, cerebrospinal fluid, pleural and peritoneal fluid, saliva, and tears, important evidence can be provided for disease diagnosis, treatment monitoring, and health assessment. In clinical practice, blood sample analysis can detect blood cell counts, biochemical indicators, immune markers, tumor markers, hormone levels, etc., providing key information for the early diagnosis and differential diagnosis of infectious diseases, hematological diseases, metabolic diseases, autoimmune diseases, and various tumors.

[0003] In the process of sample analysis, it is often necessary to dilute the original sample to adjust the concentration to the appropriate detection range of the analytical instrument. However, when using traditional operating methods, it is difficult to ensure the accuracy of the amount of diluent added, and errors are easily generated due to differences in operating techniques. In addition, it will increase the chance of the sample coming into contact with the external environment, which will not only easily cause sample contamination or cross-contamination, but also further interfere with the reliability of the analysis results. Therefore, the present invention provides a medical sample analysis device to solve the above problems. Summary of the Invention

[0013] Preferably, the bottom surface of the workbench is fixedly connected to multiple fixed columns, and the outer surfaces of the multiple fixed columns are jointly mounted with an mounting plate. A waste liquid storage tank is mounted on the upper surface of the mounting plate. A first water pump is mounted above the mounting plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This medical sample analysis device uses a first motor to drive an electric lifting rod, simultaneously completing rotation and height adjustment. Simultaneously, an electric slide rail moves a slider, which in turn precisely aligns the discharge head below the support block with the center of the centrifuge tube opening. This effectively avoids liquid spillage caused by misalignment during manual injection. The diluent is then sequentially delivered to the discharge head via a metering pump through a delivery pipe and hose. The metering pump controls the diluent extraction volume according to a preset ratio, ensuring consistent diluent usage for each batch of samples and preventing the diluent from contacting outside air throughout the process, significantly reducing the risk of airborne microbial contamination. 2. This medical sample analysis device uses a second water pump to drive the disinfectant solution through a three-way pipe, which then distributes it to two fan-shaped spray heads. The disinfectant solution is evenly sprayed into the analysis chamber in a fan-shaped spray pattern, achieving disinfection without dead angles and effectively avoiding the problem of missed gaps in manual disinfection. Furthermore, the entire process requires no human contact, eliminating cross-contamination. In addition, a drying hot air blower, in conjunction with a filter, delivers sterile hot air into the analysis chamber, quickly drying any residual disinfectant solution after disinfection, thus preventing bacterial growth in a damp environment. This is highly practical. 3. This medical sample analysis device collects waste liquid through a collection frame, and then guides the dispersed waste liquid to the bottom through a guide plate; at the same time, the first water pump pumps the waste liquid to the waste liquid storage tank for temporary storage through a connecting pipe. The waste liquid does not come into contact with the outside air throughout the process, eliminating the traditional open transfer, reducing the risk of leakage, effectively reducing the risk of waste liquid pollution to the environment, and also reducing the labor cost of laboratory waste liquid treatment.

The end of the delivery pipe 11 away from the metering pump 9 passes through the analysis box 4 and is connected to a flexible hose 27. The end of the flexible hose 27 away from the delivery pipe 11 passes through the support block 47 and is connected to the outer surface of the discharge head 44.

[0020] Furthermore, a disinfectant storage tank 6 is installed on the upper surface of the workbench 1. The workbench 1 is the basic support platform of the device, used to fix core components such as the analysis tank 4, diluent storage tank 5, and disinfectant storage tank 6, providing a horizontal operating surface to ensure the stability of each component. It stores disinfectants such as alcohol and chlorine-containing disinfectants to provide raw materials for component disinfection and avoids exposure and contamination of the disinfectant. A second water pump 23 is installed above the workbench 1. The input end of the second water pump 23 is connected to the outer surface of the disinfectant storage tank 6, and the output end of the second water pump 23 is connected to an infusion pipe 7. The end of the infusion pipe 7 away from the second water pump 23 is connected to a three-way pipe 8, which connects the infusion pipe 7 to two infusion branch pipes 16, so as to... The single disinfectant pipeline is split into two streams to simultaneously disinfect different areas within the analyzer 4. The outer surface of the three-way pipe 8 is connected to two infusion branch pipes 16, which connect the three-way pipe 8 to the fan-shaped spray head 41. The split disinfectant is delivered to the spray head. The end of each infusion branch pipe 16 away from the three-way pipe 8 passes through the analyzer 4 and is connected to the fan-shaped spray head 41. The controller 17 starts the second water pump 23. The disinfectant in the disinfectant storage tank 6 enters the three-way pipe 8 through the infusion pipe 7, and then is delivered to the fan-shaped spray head 41 inside the analyzer 4 through the two infusion branch pipes 16. The fan-shaped spray head 41 sprays disinfectant into the interior of the analyzer 4 to achieve disinfection and avoid cross-contamination.

[0021] Furthermore, a first fixing block 29 is fixedly connected inside the analysis chamber 4, serving as the mounting carrier for the centrifugal motor 36. This block absorbs vibrations during high-speed motor operation, ensuring centrifugal stability. The centrifugal motor 36 is mounted on the inner top wall of the first fixing block 29. A turntable 33 is mounted after the output end of the centrifugal motor 36 passes through the first fixing block 29. Two support plates 42 are fixedly connected to the upper surface of the turntable 33, symmetrically fixed thereon, serving as the mounting carrier for the second motor 30 and the rotating block 43, supporting the separation frame 31. The second motor 30 is mounted on the outer surface of one of the support plates 42. The rotating block 43 is mounted after the output end of the second motor 30 passes through one of the support plates 42. The separation frame 31 is fixedly connected to the outer surface of the rotating block 43. The inner surface of the separation frame 31... The unit is equipped with centrifuge tubes 32, which are placed inside the separation rack 31 to hold the sample to be diluted and the diluent. During centrifugation, the tubes rotate with the separation rack 31 to achieve sample stratification. Further, the analyzer box 4 is equipped with a collection frame 48, which has two guide plates 37. The controller 17 commands the centrifuge motor 36 on the first fixed block 29 to start, and its output drives the turntable 33 to rotate, which in turn drives the support plate 42 on the turntable 33 and the separation rack 31 to rotate synchronously for centrifugation. After centrifugation is completed, the controller 17 starts the second motor 30 on one of the support plates 42, and its output drives the rotating block 43 to rotate, adjusting the tilt angle of the separation rack 31 and pouring the waste liquid separated in the upper layer into the collection frame 48. Then, the waste liquid is guided to the bottom plate of the collection frame 48 by the two guide plates 37.

[0022] Furthermore, multiple fixed posts 24 are fixedly connected to the bottom surface of the workbench 1, vertically fixed to the bottom surface of the workbench 1, to support the mounting plate 39, so that the waste liquid storage tank 38 and the first water pump 20 are located below the workbench 1, saving the operating space above. The outer surfaces of the multiple fixed posts 24 are jointly mounted with the mounting plate 39, which serves as the mounting carrier for the waste liquid storage tank 38 and the first water pump 20. The waste liquid storage tank 38 is mounted on the upper surface of the mounting plate 39, and the first water pump 20 is mounted above the mounting plate 39. The output end of the first water pump 20 is connected to the outer surface of the waste liquid storage tank 38, and the input end of the first water pump 20 is connected to a connecting pipe 19, which connects the collection frame 48 and the first water pump. 20, serving as a channel for waste liquid transportation, extends to the bottom of the collection frame 48 to ensure thorough extraction of waste liquid. The end of the connecting pipe 19 away from the first water pump 20 passes through the analysis box 4 and connects to the outer surface of the collection frame 48. A first electronic valve 18 is installed on the outer surface of the connecting pipe 19. A drain pipe 22 is connected to the outer surface of the waste liquid storage tank 38. A second electronic valve 21 is installed on the outer surface of the drain pipe 22. The controller 17 opens the first electronic valve 18 and starts the first water pump 20. The waste liquid is pumped through the connecting pipe 19 to the waste liquid storage tank 38 on the mounting plate 39 for temporary storage. Periodically, by opening the second electronic valve 21, the waste liquid is discharged to the subsequent treatment facility through the drain pipe 22.

[0023] Furthermore, multiple hydraulic rods 2 are fixedly connected to the bottom surface of the workbench 1. These rods are installed on the bottom surface of the workbench 1, allowing for height adjustment to accommodate different operator heights or work environments. Simultaneously, a fixing plate 3 ensures stable placement of the device. The output end of each hydraulic rod 2 is fixedly connected to a fixing plate 3, with its bottom surface in contact with the ground, increasing the contact area between the device and the ground and preventing the device from tipping over due to a shift in the center of gravity. A detector 40 is installed on the inner top wall of the analysis chamber 4. After centrifugation, the controller 17 commands the centrifuge motor 36 to stop. Once the turntable 33 is stable, the detector 40 on the inner top wall of the analysis chamber 4 is activated to test the stratified samples within the centrifuge tubes 32. A drying hot air blower 13 is installed on the outer surface of the analysis chamber 4, with a filter 12 installed at the input end of the drying hot air blower 13. After sterilization, the controller 17 activates the drying hot air blower 13. 3. After being filtered by filter 12 to remove microorganisms and dust, the outside air becomes sterile hot air and is sent into the analysis chamber 4 to dry the sterilized components and the inside of the analysis chamber 4. A controller 17 is installed on the outer surface of the analysis chamber 4 for easy use by staff. The front of the analysis chamber 4 is hinged with a door 14, and an observation window 15 is opened on the front of the door 14. After opening the door 14 on the front of the analysis chamber 4, the sample to be analyzed, such as blood or cerebrospinal fluid, is put into the centrifuge tube 32 and the centrifuge tube 32 is fixed in the separation rack 31. After closing the door 14, the internal working condition can be observed through the observation window 15. The outer surface of the diluent storage tank 5 is connected to the feed pipe 10. The inside of the diluent storage tank 5 is equipped with a liquid level sensing module 34, which adopts an immersion type liquid level sensor to detect the remaining amount of diluent in real time. When it is lower than the threshold, a signal is sent to the controller 17 to trigger a replenishment prompt.

[0024] The working principle of this invention is as follows: During the sample dilution preparation stage, the staff sends a command to the controller 17 to start the first motor 35. The first motor 35 then drives the electric lifting rod 26 to synchronously complete the rotation and lifting action. The lifting height is adjusted to a suitable position according to the actual placement height of the centrifuge tube 32, ensuring that the subsequent movement path of the discharge head 44 is unobstructed and laying the foundation for its precise docking with the tube opening area of ​​the centrifuge tube 32. At the same time, the electric slide rail 45 on the bottom surface of the support column 25 is activated and drives the slider 46 to move smoothly along the slide rail. The slider 46 further drives the support block 47 connected at the top and the discharge head 44 fixed below the support block 47 to move synchronously, ultimately making the liquid outlet of the discharge head 44 precisely aligned with the center of the tube opening of the centrifuge tube 32, thus avoiding liquid splashing during subsequent liquid injection from the source. In case of leakage, after the position calibration is completed, the staff will trigger the start command of the metering pump 9 again through the controller 17. At this time, the diluent in the diluent storage tank 5 will be stably drawn out under the negative pressure of the metering pump 9. The metering pump 9 will strictly control the diluent delivery volume according to the preset dilution ratio to ensure that the concentration of the diluted sample is completely within the detection range of the analyzer. Then, the accurately metered diluent enters the analyzer chamber 4 through the chemical corrosion resistant delivery tube 11, and then through the highly flexible hose 27, which can flexibly deform with the movement of the discharge head 44, and is delivered to the discharge head 44 without rigid constraints. Finally, it is slowly and uniformly injected into the centrifuge tube 32. This injection rate can effectively avoid sample loss or contamination caused by liquid impacting the tube wall. After the injection is completed, the sample dilution operation is successfully completed.
