Technical Field

[0001] The invention relates to the technical field of medical detection instruments, and in particular to a blood gas analysis mixing and shaking device for a laboratory. Background Art

[0002] Blood gas analysis in the laboratory is a more advanced type of blood biochemical examination. It mainly tests different types of gases and acid-base substances in blood samples to provide important information about the patient's acid-base balance, oxygenation status and electrolyte status. Blood gas analysis can be used for diagnosis, first aid and nursing. At the same time, blood gas analysis can also clearly reflect the changes in a variety of substances, so it can screen out as many as dozens of diseases. The blood gas analysis in the laboratory requires a mixing device because blood gas analysis measures the partial pressure and content of gas components (such as O2, CO2, etc.) dissolved in the blood, and measures the relevant indicators of acid-base balance to understand ventilation function, respiratory failure and severity, and various types of acid-base imbalance.

[0003] After the staff takes the blood gas sample, it needs to be mixed and shaken to ensure that the gas and liquid components in the blood sample can be fully mixed, so as to obtain more accurate measurement results. However, in the actual sampling process, due to differences in factors such as the staff's technical level, the environment in which the blood gas sample is located, and the standing time of the blood gas sample before shaking, the state properties of the blood gas sample will change to a certain extent, thereby affecting the inspection and analysis of the blood gas sample after shaking, and further causing deviations in the measurement results, affecting the accuracy of the diagnosis.

[0035] See also Figures 1 to 7 The present invention provides a blood gas analysis mixing device for a laboratory, comprising:

[0036] A closed protective shell 1, on the inner wall of the bottom thereof, a sample moving and adjusting component 2 is fixedly mounted, and a mixing and shaking component 7, an ultrasonic cleaner 9, and a wind dryer 10 are also fixedly mounted on the inner wall of the bottom of the closed protective shell 1, a scanning detector 3, and a medical centrifuge 4 are provided with a support seat 12 at the lower end, and a water bath cooling component 5 and a water area heating component 6 are provided with a support frame 13 at the lower end, and the support seat 12 and the support frame 13 are both fixedly mounted on the inner wall of the bottom of the closed protective shell 1;

[0037] A sterile syringe 8 is fixedly mounted on the inner wall at the top of the sealed protective shell 1;

[0038] As a preferred embodiment, the sealed protective shell 1 can maintain airtightness to a certain extent, and while protecting the safety of various components in the device, prevent bacteria, dust and other impurities from entering the device and causing certain contamination to the blood gas sample. At the same time, the sealed protective shell 1 has built-in components such as temperature and humidity controllers that are not explicitly stated, which can further ensure the overall conditions inside the device, thereby preventing the blood gas sample from being affected and changed by external factors, thereby causing deviations in the measurement results and affecting the accuracy of the diagnosis. The sample moving and adjusting component 2 can drive the blood gas sample to rotate, so that after being scanned and detected by the scanning detector 3, it can be rotated according to its detection results. The medical centrifuge 4, the water bath cooling component 5, the water area heating component 6, the mixing and shaking component 7, the sterile syringe 8 and other instruments are operated, and then the blood gas sample that meets the requirements is extracted for blood gas analysis. At the same time, the inside of the device will be cleaned by the ultrasonic cleaner 9 to remove the residual blood gas therein, and then after passing through the wind dryer 10, it will continue to serve the subsequent blood gas samples, wherein the ultrasonic cleaner 9 can clean the residual blood gas in the device to prevent it from contaminating the subsequent blood gas samples, and the wind dryer 9 can remove the residual water after the ultrasonic cleaner 9 is cleaned to prevent it from diluting the subsequent blood gas samples, thereby affecting the accuracy of the diagnosis;

[0039] The scanning detector 3 can analyze and detect the basic properties of the blood gas sample to prevent certain conditions from not meeting the standards and affecting the accuracy of the subsequent analysis and detection results. At the same time, according to the detection results, it can be processed according to its properties so that its conditions can reach the best detection conditions, thereby further ensuring the accuracy of the detection results. Blood samples that have coagulated due to improper use of anticoagulants or long sample placement time are usually unable to be analyzed for blood gas, and the sample needs to be recollected. However, in real life, there may be situations where sample collection is difficult or even impossible to recollect. In this case, the coagulated blood gas sample can be placed in a medical centrifuge 4 and centrifuged to separate the coagulated blood from the plasma, and By analyzing the plasma for sexual diagnosis, the water bath cooling component 5 and the water bath cooling component 6 ensure that the temperature of the sample before shaking is within an appropriate range through water bath conduction, preventing the sample temperature from being too high or too low, which affects the results of blood gas analysis. The sterile syringe 8 can puncture the bubbles generated during the sampling and processing of the blood sample, preventing the presence of bubbles from affecting certain parameters (such as PO2) in the blood gas analysis, thereby affecting the accuracy of the results. The mixing and shaking component 7 can vibrate, shake, and turn upside down according to the properties of the blood gas sample, thereby ensuring the uniformity of the blood gas sample, while preventing the mixing time from being too long, resulting in red blood cell rupture or other unnecessary chemical reactions, thereby affecting the results of blood gas analysis.

[0040] Furthermore, three groups of syringe operation interfaces 11 are arranged above the sealed protective shell 1, and the three groups of syringe operation interfaces 11 are respectively located directly above the scanning detector 3, the medical centrifuge 4, and the ultrasonic cleaner 9;

[0041] As a preferred embodiment, the syringe operation interface 11 can be used by staff or external devices to insert a syringe and perform corresponding operations, and in a non-working state, the syringe operation interface 11 is in a closed state. The setting of the syringe operation interface 11 above the scanning detector 3 allows the staff or external devices to inject the collected blood gas sample into a specified position in the device. During the centrifugation process, due to the action of centrifugal force, different components in the blood sample will be separated due to density differences; the blood clot will be pushed to the bottom of the centrifuge tube due to its higher density, while other components, such as plasma, platelets and red blood cells, will be distributed at different positions above the blood clot according to their respective density differences. Therefore, when the operation of the medical centrifuge 4 is completed, the internal blood clot can be removed through the syringe operation interface 11 directly above it, which is convenient for subsequent processing of the sample. The syringe operation interface 11 directly above the ultrasonic cleaner 9 can extract the blood gas sample before the ultrasonic cleaner 9 works, so that it can participate in the subsequent blood gas analysis operation.

[0042] Furthermore, the sample moving and positioning component 2 includes:

[0043] A fixing seat 21 is fixedly mounted on the inner wall of the bottom of the sealed protective shell 1, and a first driving motor 22 is fixedly mounted on the upper end thereof. A rotating plate 23 is horizontally fixedly mounted on the output shaft of the first driving motor 22, and eight groups of sample adjustment components 24 are fixedly mounted on the rotating plate 23;

[0044] As a preferred embodiment, the sample positioning component 24 is uniformly controlled by an external control system, and the control system can receive the detection results of the scanning detector 3, and plan the processing steps of the sample according to the detection results, thereby controlling the sample positioning component 24 to adjust the relative position of the blood gas sample at the step where processing is required to facilitate the processing operation.

[0045] Further, the sample positioning component 24 includes:

[0046] Two groups of fixed columns 241 are vertically arranged and fixedly assembled on the rotating plate 23. The upper ends of the two groups of fixed columns 241 are fixedly assembled with fixed connecting plates 242. Two groups of transmission screws 244 are vertically rotatably arranged between the fixed connecting plates 242 and the rotating plate 23. The upper ends of each group of transmission screws 244 are coaxially fixedly assembled on the output shaft of the second driving motor 243. The second driving motor 243 is fixedly assembled on the upper surface of the fixed connecting plate 242.

[0047] Each group of the driving screws 244 is threadedly mounted with a threaded lifting block 245, and the lower surfaces of the two groups of the threaded lifting blocks 245 are fixedly mounted with a lifting bearing plate 246, and a sample tube self-driving assembly 247 is fixedly embedded in the middle of the lifting bearing plate 246, and a sample tube group 248 is arranged inside the sample tube self-driving assembly 247;

[0048] As a preferred embodiment, through the rotation of two groups of second drive motors 243, the threaded lifting block 245 can drive the sample tube group 248 to move up and down, so that the sample tube group 248 can be moved to a suitable position in front of the corresponding processing device, which is convenient for the processing of blood gas samples. The sample tube self-driving component 247 can clamp the sample tube group 248, and it can shrink to a certain extent, so as to clamp sample tube groups 248 of different diameters. At the same time, the sample tube self-driving component 247 can drive the sample tube group 248 to further rise and fall, so as to further ensure the processing of blood gas samples.

[0049] Furthermore, eight groups of sample tube rotating grooves 25 are provided on the rotating plate 23, and the eight groups of sample tube rotating grooves 25 correspond to eight groups of sample position adjustment components 24;

[0050] As a preferred embodiment, the sample rotating tank 25 can provide sufficient space support for the sample tube group 248 when performing an upside-down shaking operation.

[0051] Further, the sample tube set 248 includes:

[0052] The sample tube 2481 is arranged inside the sample tube self-driving assembly 247. A sealing piston 2482 is coaxially slidably arranged inside the sample tube 2481. A ball joint rotator 2483 is arranged in the middle of the sealing piston 2482. A needle entry tube 2484 is fixedly arranged in the middle of the ball joint rotator 2483. A switch valve 2485 is arranged at the upper end of the needle entry tube 2484.

[0053] As a preferred embodiment, the setting of the sealing piston 2482 can further ensure the airtightness of the blood gas sample and prevent the blood gas sample from being contaminated. The setting of the ball joint rotator 2483 can allow the syringe or sterile syringe 8 to move within a certain range after entering the sample tube 2481, thereby ensuring the thorough removal of blood clots or bubbles.

[0054] Further, the mixing and shaking assembly 7 comprises:

[0055] A vibrator 71 is fixedly mounted on the inner wall at the bottom of the sealed protective shell 1. A shaking hydraulic group 72 is rotatably arranged on the upper end of the vibrator 71. A fixing plate 74 is fixedly arranged on the upper end of the shaking hydraulic group 72. A third driving motor 73 is fixedly mounted on the upper end of the vibrator 71. The output shaft of the third driving motor 73 is fixedly mounted on the fixing plate 74.

[0056] As a preferred embodiment, different sample types require different mixing methods and parameter settings. In actual operation, the appropriate mixing method and parameter settings are selected according to the sample characteristics to ensure the accuracy and reliability of blood gas analysis. The vibrator 71 can enable the device to drive the sample to vibrate at high frequency and mix it in a gentle manner, which can avoid excessive bubbles or hemolysis in the sample to a certain extent, further improving work efficiency. The shaking hydraulic group 72 can adjust the deflection angle of the sample tube group 248 through the elongation length of each group of hydraulic cylinders therein, and then achieve the purpose of shaking and mixing through the third drive motor 73. It moves within a larger range to make the gas and liquid in the sample more fully integrated, further ensuring the test results.

[0057] Furthermore, a bidirectional hydraulic cylinder 79 is fixedly mounted on the fixed plate 74, and sliding support frames 75 are vertically fixedly mounted on both ends of the bidirectional hydraulic cylinder 79. Two sets of the sliding support frames 75 are mirror-imaged and slidably mounted on the fixed plate 74, and sample tube fixing sections 76 are rotatably mounted on the inner sides of the two sets of the sliding support frames 75.

[0058] A fourth drive motor 77 is disposed on the right side of the sliding support frame 75, and a transmission group 78 is disposed on the output shaft of the fourth drive motor 77, and the other end of the transmission group 78 is fixedly connected to the corresponding sample tube fixing section 76;

[0059] As a preferred embodiment, before shaking, no matter which shaking method is selected, the sample tube group 248 will temporarily separate from the sample positioning assembly 24 through the sample tube self-driving assembly 247, so as to facilitate the mixing and shaking assembly 7 to perform shaking, and before the sample tube group 248 separates from the sample positioning assembly 24, the bidirectional and hydraulic cylinder 79 will contract so that the two groups of sample tube fixing sections 76 clamp the sample tube group 248, thereby ensuring the safety of the sample tube group 248. The setting of the fourth driving motor 77 can rotate the sample tube group 248 by rotating the sample tube fixing section 76, so that the blood gas sample is shaken in the form of upside down inversion to ensure that the gas and liquid components in the sample are fully mixed.

[0060] Furthermore, the two groups of sample tube fixing sections 76 are arranged in a mirror image, and a sample tube protection pad 710 is fixedly arranged in the middle of the inner side.

[0061] When implemented specifically, the following steps are included: a worker or an external device injects a blood gas sample into a sample tube group 248 in the device through a syringe operation interface, the sample tube group 248 is moved to a suitable position through a sample moving and positioning component 2, and then a scanning detector 3 scans the sample tube group 248 and uploads the scanning result to an external control system. The control system processes and determines the blood gas sample according to the test result and the actual situation, and analyzes whether it needs to be processed by a medical centrifuge 4, a water bath cooling component 5, a water area heating component 7, and a sterile syringe 8. Processing is carried out. If processing is required, the sample tube group 248 is moved to a suitable position by moving the adjustment component 2 and then processed. At the same time, a mixing operation will be performed in front of the sterile syringe 8 (the mixing method is determined by the sample type and actual situation). After the processing is completed, the blood gas sample will be extracted from the device through the syringe operation interface 11 above the ultrasonic cleaner 9 for blood gas analysis. At the same time, the inside of the device will be targetedly cleaned by the ultrasonic cleaner 9 to remove the residual blood gas therein, and then after passing through the wind dryer 10, it will continue to serve the subsequent blood gas samples.

[0062] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
