Description

Technical Field

[0001] The invention relates to the technical field of blood analysis, in particular to a portable multi-parameter blood electrolyte analyzer. Background Art

[0002] The multi-parameter blood electrolyte analyzer can simultaneously detect multiple electrolyte parameters in the blood, such as potassium ions (K+), sodium ions (Na+), chloride ions (Cl-), ionized calcium (Ca++), etc. It can meet various clinical needs by detecting the specific parameters of electrolytes in the blood.

[0003] For example, the patent publication number is "CN109444394A" and the name is "Blood Gas Biochemical Analyzer", which includes a heater assembly installed in the housing, and the heater assembly is used to heat the test area of ​​the test card; a reagent filling control structure is installed in the housing, and the reagent filling control structure includes a top valve member and an extrusion member, the top valve member is used to press the top valve plate to connect the reagent flow channel of the test card with the test chip, and the extrusion member is used to squeeze the reagent package of the test card so that the reagent in the reagent package flows to the test chip through the reagent flow channel. The present invention has the advantages of short test cycle, high test accuracy, and easy to carry and use.

[0004] The above device detects the parameters in the blood by inserting the card, so that the above device can only detect a single blood sample. When testing multiple blood samples, the card needs to be inserted and tested in sequence, which takes a long time. In addition, when using a single detection channel to detect multiple blood samples, the blood sample residue inside the detection pipeline may affect the detection of subsequent blood samples. After a single test is completed, the inside of the detection channel needs to be cleaned. In order to ensure the subsequent blood test data, flushing with a cleaning agent will cause liquid to remain inside the detection pipeline. At the same time, negative pressure or pressurization technology is used to flush with gas, which is still prone to adhesion. The presence of impurities affects subsequent tests and affects the accuracy of test data. For this reason, a portable multi-parameter blood electrolyte analyzer is invented.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Feed assembly No. 1 includes a storage cylinder 402, which is fixedly installed inside the casing 1, the discharge end of the storage cylinder 402 is fixed to the feed end No. 1 of the fixed cylinder 401, the interior of the storage cylinder 402 is slidably connected with a piston 403, and a telescopic part No. 1 404 is fixedly connected between the piston 403 and the casing 1 for controlling the piston 403 to slide inside the storage cylinder 402.

[0033] Feeding assembly No. 2 includes motor No. 1, which is fixedly installed inside the box body 1, and the output end of motor No. 1 is fixedly connected to a placement rack 405, and the interior of the placement rack 405 is slidably connected to a moving part 406, and a storage assembly 7 for storing blood samples is installed inside the moving part 406, and a No. 3 telescopic part 407 for controlling the movement of the moving part 406 is fixedly connected to the top of the box body 1, and a No. 3 spring shock-absorbing damper 408 is fixedly connected between the moving part 406 and the placement rack 405, and a No. 4 telescopic part 409 for feeding the blood sample inside the storage assembly 7 into the interior of the fixed cylinder 401 is fixedly connected to the top of the box body 1, and a leak-proof assembly 8 is fixedly connected to the feeding end of the fixed cylinder 401 for feeding the blood sample.

[0034] The storage assembly 7 includes a storage bottle 701 , which is installed inside the moving member 406 , and a moving plate for squeezing out the blood sample is slidably connected inside the storage bottle 701 .

[0035] The leak-proof component 8 includes a leak-proof part 801, the outer wall of the leak-proof part 801 is slidably connected to the inner wall of the fixed tube 401, the outer wall of the leak-proof part 801 is provided with a through hole for the storage bottle 701 to squeeze out the internal blood sample, and a spring shock-absorbing damper 802 is fixedly connected between the leak-proof part 801 and the fixed tube 401.

[0036] The air intake assembly includes an air intake pipe, which is fixedly installed on the outer wall of the fixed cylinder 401. The feed end of the fixed cylinder 401 is fixedly connected with an air control device for realizing suction and blowing, and the air control device is fixedly installed inside the box body 1.

[0037] The operation flow of the multi-parameter blood electrolyte analyzer is as follows: blood samples are stored through the storage assembly 7, and then the storage bottle 701 is placed on the moving part 406. At this time, a calibration sample with known parameter data is stored in the storage cylinder 402. The telescopic end of the second telescopic part 601 moves, and the push rod 602 contacts the moving rod 503, and then the moving rod 503 and the cleaning partition 504 are pushed to the inner wall of the fixed cylinder 401, so that at least two moving rods 503 exist in the fixed cylinder 401 before feeding. When there are two moving rods 503 in the fixed cylinder 401, the air control device forms a negative pressure between the two cleaning partitions 504, and then the calibration sample is firstly made to The sample enters the gap between the two cleaning partitions 504, and the distance between the two cleaning partitions 504 moves. The cleaning partition 504 at the previous position moves toward the detection channel 2, and the latter cleaning partition 504 does not move due to the presence of the moving-in component. The partitioning feed component 5 then allows the cleaning partition 504 to enter the interior of the fixed cylinder 401. The air control device forms a negative pressure in the gap between the latter two cleaning partitions 504, and then allows the blood sample to enter. The partitioning feed component 5 allows the cleaning partition 504 to enter the interior of the fixed cylinder 401. At this time, the calibration sample enters. Repeating the above cycle can realize the detection of the blood sample.

[0038] The liquid used in this application refers to the general term for blood samples and calibration samples, but the two will not come into contact during the actual detection process. In order to avoid the use of the same channel in the blood samples and the influence of the previous blood sample on the next blood sample, a leak-proof component 8 is used in the design. The storage bottle 701 moves and contacts the interior of the storage bottle 701. One end of the storage bottle 701 is adapted to the interior of the moving member 406. The storage bottle 701 and the moving member 406 move synchronously. The discharge hole of the storage bottle 701 is opened at the side wall position. The moving plate moves so that the blood sample moves out from the overlapping position of the discharge hole and the through hole and enters the interior of the fixed cylinder 401. In order to achieve the overlap of the discharge hole and the through hole position, since the position of the through hole is fixed, a mounting groove can be provided on the moving member 406, and a mounting protrusion can be provided on the storage bottle 701 so that the mounting groove and the mounting protrusion are in contact, thereby limiting the position of the discharge hole on the storage bottle 701 and achieving the overlap of the discharge hole and the through hole position. The design enables the storage bottle 701 to directly squeeze the blood sample into the fixed cylinder 401, the telescopic end of the No. 3 telescopic member 407 moves and contacts the moving member 406, thereby causing the moving member 406 to contact the leak-proof member 801, the No. 3 spring shock-absorbing damper 408 is stretched, the telescopic end of the No. 4 telescopic member 409 moves and contacts the moving plate, and the blood sample enters the fixed cylinder 401, thereby avoiding the influence of the previous blood sample on the subsequent blood sample. Through the arrangement of the No. 2 feeding component and the leak-proof component 8, when the blood sample is fed, it enters the fixed cylinder 401 through the through hole on the leak-proof member 801, and then feeds the fixed cylinder 401 through the No. 2 feeding component. The design can avoid the situation where different blood samples will come into contact at the feeding point, thereby avoiding the possibility of affecting the parameters in the blood sample at the feeding position, and ensuring the detection accuracy of the analyzer. The No. 1 spring shock-absorbing damper 802 enables the leak-proof member 801 to return to its original position when it is not in contact with the storage bottle 701.

[0039] When the telescopic end of the No. 2 telescopic member 601 contracts, the removal member 605 moves synchronously, so that the placement member 502 can be moved out of the fixed frame 501. Due to the presence of the No. 2 spring shock absorber 603 and the pressure plate 604, the placement member 502 at the next position is moved to the original position to continue to move in the cleaning partition 504.

[0040] There is prior art for parameter detection components, and the detection principle thereof is mainly based on ion selective electrode measurement method and potential method. The specific structure and principle of the parameter detection component are not described here. The parameter detection component is composed of a plurality of parameter detection devices combined with each other, and they will not interfere with each other during detection. The blood sample continuously passes through the area occupied by the detection unit of the parameter detection component on the detection channel 2. Due to the movement of the blood sample, the parameter detection component continues to detect. When the area occupied by the parameter detection component passes through the cleaning partition 504, and the rubber used for the cleaning partition 504 is an insulating material, the electrode data detected by the parameter detection component is zero. A control terminal is provided to receive the data sent back by the parameter detection component in real time. When it is detected to be zero, data wrapping can be achieved, that is, the next portion of liquid is detected, and there will be no mutual interference between the data.

[0041] The first telescopic member 404 and the second telescopic member 601 can realize the free movement of the telescopic end, and there is the prior art, so the interior of the first telescopic member 404 and the second telescopic member 601 will not be specifically described here. The calibration sample is a liquid with known internal electrolyte parameter data, and the amount of electrolytes in it is the same as the amount of electrolytes in the blood sample. The calibration sample passes through the detection channel 2, and the parameter detection component detects the calibration sample. By comparing the obtained parameter data with the parameter data of the actual calibration sample, the internal correction of the parameter detection component can be realized. At the same time, because the multi-parameter blood electrolyte analyzer realizes alternating movement between the calibration sample and the blood sample, This design can improve the accuracy of the detection of the internal parameter data of the blood sample. The calibration sample of the previous blood sample is passed through the parameter detection component to obtain the No. 1 detection parameter data, and the calibration sample of the second blood sample is passed through the parameter detection component to obtain the No. 3 detection parameter data. The internal parameter data of the calibration sample is known. The No. 1 detection parameter data is compared with the parameter data of the known calibration sample, and the No. 3 detection parameter data is compared with the parameter data of the known calibration sample. It can be determined whether there is contamination in the detection channel 2, and then the parameter data detected by the blood sample is processed so that the processed parameter data can be closer to the actual parameter data in the blood sample.

[0042] The air control device can realize two functions of suction and blowing. Since the cleaning partition 504 is preferably made of rubber material, the inner wall of the fixed cylinder 401 and the inner size of the detection channel 2 are the same, and the outer wall size of the cleaning partition 504 is larger than the inner wall size of the fixed cylinder 401 when there is no external force. Therefore, the cleaning partition 504 cannot be directly pushed into the fixed cylinder 401. Forcing it in may easily cause the outer wall of the cleaning partition 504 to deform, resulting in a gap between the fixed cylinder 401 and the cleaning partition 504, which may cause mutual influence between the liquid at the front end and the liquid at the rear end of the cleaning partition 504. Therefore, a moving rod 503 is provided. In daily storage, that is, before use, the moving rod 503 is placed through the placing piece 502 to avoid the cleaning partition 504 from being moved. During daily storage, squeezing will be caused, which will affect the deformation ability of the cleaning partition 504. At the same time, when the cleaning partition 504 is moved, the moving rod 503 is pushed to move the cleaning partition 504 to the inside of the fixed cylinder 401. At the same time, the setting of the moving rod 503 makes two adjacent moving rods 503 contact each other inside the fixed cylinder 401, so that there will be a gap between the two cleaning partitions 504, and the gap can allow the blood sample or calibration sample to enter. The gap between the two cleaning partitions 504 is first sucked by the air control device, and then the entry of the blood sample or calibration sample is controlled by the No. 1 feeding component or the No. 2 feeding component. When the air control device blows, the speed needs to be controlled to ensure that the blood sample and the calibration sample have enough time to come into contact with the detection unit of the parameter detection component.

[0043] When only a single or last blood sample is tested, an air control device will be used. When no blood sample is subsequently introduced, the air control device blows air into the gap between the two cleaning partitions 504, so that the internal air pressure between the two cleaning partitions 504 increases, so that the two cleaning partitions 504 have a tendency to move. A recovery device is installed at the discharge end of the detection channel 2. In order to ensure the smooth movement of the cleaning partition 504 inside the detection channel 2, a negative pressure device can be additionally installed at the discharge end of the detection channel 2 to form a negative pressure at one end of the detection channel 2 close to the discharge end. The negative pressure can be used to move the liquid and the partition assembly inside the detection channel 2 to the discharge end position of the detection channel 2. The internal pressure between the two cleaning partitions 504 is reduced. The internal air pressure increases, which squeezes the cleaning partition 504 in the previous position, thereby enabling it to move. The next cleaning partition 504 and the moving rod 503 have a tendency to move backward, but at this time the moving rod 503 will be restricted by the moving rod 503 on the fixed frame 501, so that the next cleaning partition 504 and the moving rod 503 cannot move. The air control device continues to intake air, so that the previous cleaning partition 504 can completely pass through the inside of the detection channel 2. The same is true when the No. 1 feeding component and the No. 2 feeding component are respectively fed with blood samples or calibration samples. The collecting device 3 collects and cleans the cleaning partition 504, the blood sample and the calibration sample. At the same time, the cleaning partition 504 and the moving rod 503 are reusable The components can be reused after being disinfected, cleaned and dried after one use. By setting the detection channel 2, the alternating component and the partition feeding component 5, the blood sample and the calibration sample can be alternately fed into the detection channel 2. The parameters in the liquid are detected by the parameter detection component. The blood sample and the calibration sample are separated by the cleaning partition 504. At the same time, the cleaning partition 504 can clean the inside of the detection channel 2 during the movement inside the detection channel 2, thereby reducing the influence between the blood samples. The presence of the calibration sample enables the calculated parameter data of the blood sample to be close to the actual value during the subsequent detection and calculation of the blood sample. Therefore, the electrolyte analyzer shortens the detection time and ensures the feasibility of the electrolyte analyzer. By setting the cleaning partition 504 and the moving rod 503, the cleaning partition 504 can be separated from the front end area and the rear end area of ​​the cleaning partition 504 during its movement inside the detection channel 2. By using the moving rod 503, a gap is created between two adjacent cleaning partitions 504, and liquid or gas can be introduced into the two cleaning partitions 504 through the gap. Due to the internal pressure of the liquid or gas, the movement of the cleaning partition 504 is achieved. In this way, the blood sample and the calibration sample are alternately introduced, and the movement of the liquid inside the detection channel 2 is controlled. The cleaning partition 504 can clean the inside of the detection channel 2, avoid mutual influence between liquids, and ensure the practicality of the analyzer.
