Description

Technical Field

[0001] This utility model relates to the field of in vitro diagnostic equipment technology, specifically to a reagent kit component for a blood gas analyzer and a blood gas analyzer. Background Technology

[0002] A blood gas analyzer uses electrodes to react electrochemically with a blood sample, converting the chemical components in the blood into electrical signals to measure the partial pressure of oxygen (dissolved oxygen), pH value, partial pressure of carbon dioxide, electrolyte concentration, and other parameters. Current blood gas analyzers typically consist of three parts: a test card, a reagent kit, and the analyzer itself. The test card and reagent kit are removable consumables and need to be replaced frequently during actual use.

[0003] The analyzer main unit, test card, and reagent kit all have liquid paths. The test card contains multiple detection electrodes. After the test solution (usually a blood sample) enters the test card, it contacts the detection electrodes. The detection electrodes detect the parameters in the test solution and output an electrical signal, which is used to obtain the detected parameters. The reagent kit also has liquid paths, and it typically contains one or more liquid packets. The liquid in these packets can be conducted to the liquid paths of the test card.

[0004] Blood oxygenation measurement refers to measuring the oxygen saturation (different from oxygen partial pressure) in a blood sample, and it is generally performed using spectrophotometry. The principle of spectrophotometry can be summarized as follows: the blood sample to be tested is placed in the sample chamber of a sample container. First, the blood cells in the blood sample are broken up by ultrasound, releasing hemoglobin. Then, detection light is emitted to the blood sample in the sample container. Since hemoglobin absorbs light of different wavelengths differently, the proportion of hemoglobin in various blood samples can be calculated.

[0005] In related technologies, blood gas analyzers and pulse oximeters are two independent devices, requiring separate blood gas analysis and pulse oximetry measurements on two separate instruments. In some blood gas analyzers with pulse oximetry capabilities, the sample container is only attached to the reagent kit at one end, leaving the other end suspended. This results in low sample container stability. Furthermore, the light source and ultrasonic devices need to contact the sample container from opposite sides before measurement. The light source or ultrasonic devices can easily cause slight movement or deflection of the sample container, leading to deformation at the connection point between the sample container and the reagent kit, affecting the stability of the connection.

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

[0025] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0026] In related technologies, blood gas analyzers and pulse oximeters are two independent devices, requiring separate blood gas analysis and pulse oximetry measurements on different instruments. Because traditional blood gas analyzers only perform blood gas analysis, their functionality is relatively limited. To enable blood gas analyzers to measure parameters such as pulse oximetry (e.g., pulse oximetry saturation), some blood gas analyzers integrate sample containers, ultrasonic devices, luminescence devices, and spectrometers necessary for pulse oximetry measurement. These blood gas analyzers with pulse oximetry measurement capabilities mainly include the analyzer main unit, reagent kit components, test card components, sample containers, ultrasonic devices, luminescence devices, and spectrometers.

[0027] The reagent kit and test card assembly are consumables required for blood gas analysis measurements using a blood gas analyzer. The reagent kit includes a reagent kit and components such as a delivery pump, reagent pack, waste bag, and connecting tubing. The reagent pack contains calibration solution, and the waste bag collects waste liquid after testing. When the reagent kit and test card assembly are installed in the analyzer, the connecting tubing within the reagent kit connects to the blood gas testing channel inside the test card assembly. During blood gas parameter measurement, the test solution flows through the connecting tubing within the reagent kit to the blood gas testing channel inside the test card assembly, where the detection electrode detects the test solution. The sample container, ultrasonic device, and luminescence device are typically fixed to the analyzer. The sample container has a blood oxygenation testing channel for the test solution to pass through. The ultrasonic device emits ultrasonic waves into the sample container, which act on the test solution inside. The luminescence device emits detection light into the sample container, and the spectrometer receives the detection light emitted from the sample container. During blood oxygenation measurement, a test solution is introduced into the blood oxygenation testing channel inside the sample container. Ultrasonic waves emitted by an ultrasonic device act on the test solution inside the sample container, breaking down blood cells and releasing hemoglobin. Detection light emitted by a luminescent device passes through the blood oxygenation testing channel of the sample container and is then received by an optical fiber. The fiber guides the light to a spectrometer connected to the fiber, which analyzes the light to calculate blood oxygen saturation and other blood oxygenation parameters. While this blood gas analyzer can measure both blood gas and blood oxygen parameters, the sample container, ultrasonic device, and luminescent device are typically fixed inside and cannot be moved. If the sample container malfunctions, it needs to be returned to the factory for repair, a cumbersome and time-consuming process. In other blood gas analyzers where the sample container is integrated into the reagent kit as a consumable and the ultrasound and luminescence devices can move and contact the sample container, the poor installation stability of the sample container on the reagent kit means that the ultrasound and luminescence devices can easily cause the installation position of the sample container to shift or deflect when they move. This can lead to deformation at the connection between the sample container and the reagent kit, affecting the connection stability of the sample container and the accuracy of blood oxygen parameter measurement results.

[0028] To address the aforementioned technical problems, this application proposes a reagent kit assembly and blood gas analyzer that integrates the sample container and reagent kit as consumables and features stable sample container installation.

[0029] like Figure 1 and Figure 2The blood gas analyzer shown includes a main unit housing and a main unit bracket 11 housed within the housing, a blood gas measurement module (not shown), and a blood oxygen measurement module. The blood gas measurement module is configured to detect the input sample to obtain blood gas parameters, and the blood oxygen measurement module is configured to detect the blood oxygen level of the input sample to obtain blood oxygen parameters. The main unit (not shown) is housed within the main unit housing. In this context, "main unit" can be understood as any major structure in the blood gas analyzer other than removable consumables and the blood oxygen measurement module. For example, the main unit may include a signal processing module, a human-computer interaction module, and a circuit module. The signal processing module converts the acquired electrical signals into clinically interpretable physiological parameters; the human-computer interaction module enables user operation, result viewing, and instrument settings; and the circuit module provides stable power supply and signal transmission for the entire main unit. The various modules of the main unit can be directly or indirectly fixedly mounted on the main unit bracket 11.

[0030] like Figure 1 and Figure 2 As shown, in some embodiments of this application, the main unit housing includes a base 12 and a front housing 13 and a rear housing 14 connected to the base 12. A main unit bracket 11 is mounted on the base 12. The front housing 13 and the rear housing 14 are connected to form the outer housing of the blood gas analyzer. The main unit bracket 11, the blood gas measurement module, and the blood oxygen measurement module are all located within the space enclosed by the front housing 13 and the rear housing 14. The front housing 13 is equipped with a display screen 131, a test card slot 132, a sampling needle port 133, a barcode scanning port 134, etc. The test card slot 132 is used for inserting a test card assembly, and the sampling needle port 133 is used for inserting a syringe or capillary tube. The test fluid inside the syringe or capillary tube can enter the tubing inside the main unit housing through the sampling needle port 133. The blood gas analyzer also contains various components required to realize the blood gas analysis function and the measurement functions of indicators such as blood oxygen (blood oxygen saturation), including a power supply, a printer, and a main control board.

[0031] like Figure 2 , Figure 3 and Figure 7 As shown, in some embodiments of this application, the blood oxygen measurement module includes a drive actuator 2, an ultrasonic device 3, a light-emitting device 4, and a spectrometer 6. The drive actuator 2 includes a mounting bracket 21 installed outside the main unit bracket 11, and the ultrasonic device 3, the light-emitting device 4, and the spectrometer 6 are directly or indirectly mounted on the mounting bracket 21.

[0032] like Figure 4 , Figure 5 and Figure 6As shown, in some embodiments of this application, the blood gas analyzer includes a reagent kit assembly 5, which is detachably mounted on the blood gas analyzer. The main unit support 11 has a reagent kit chamber 11c for housing the reagent kit assembly 5. The reagent kit assembly 5 is inserted into the reagent kit chamber 11c as a consumable and can be inserted into or removed from the reagent kit chamber 11c through a reagent kit assembly port on one side of the reagent kit chamber 11c. The main unit support 11 is generally cubic in shape, and the overall shape of the reagent kit assembly 5 matches the overall shape of the main unit support 11.

[0033] like Figure 2 , Figure 4 and Figure 5 As shown, the reagent kit component 5 includes a reagent kit 51 and a sample container 52. When the reagent kit component 5 is installed into the main unit support 11, the sample container 52 is installed together with the reagent kit 51 into the reagent kit chamber 11c inside the main unit support 11. This configuration allows for the integrated replacement of the sample container 52 and the reagent kit 51, eliminating the need for additional space outside the main unit support 11 for inserting the sample container 52, thus facilitating the miniaturization of the main unit support 11 and the entire device. The reagent kit 51 has a reagent pack chamber 51a inside, which can hold one or more reagent packs required for testing. Furthermore, the reagent pack chamber 51a can also hold components required for blood gas analysis testing and blood oxygen parameter measurement, such as a delivery pump, connecting tubing, and control valves.

[0034] like Figure 5 As shown, the reagent kit 51 is cubic in shape, with a groove 511 on its outer wall, within which the sample container 52 is located. The sample container 52 protrudes from the outer surface of the reagent kit 51. One end of the sample container 52 is connected to one sidewall of the groove 511, and the other end is connected to the other sidewall of the groove 511, thus securing the sample container 52 to the reagent kit 51. The location of the sample container 52 within the groove 511 on the outside of the reagent kit 51 not only reduces the additional volume occupied by the sample container 52, but also prevents unnecessary collisions and scratches between the sample container 52 and other components within the blood gas analyzer, thus protecting the sample container 52. Furthermore, the method of fixing the sample container 52 to the reagent kit 51 at both ends ensures a more stable connection between the sample container 52 and the reagent kit 51.

[0035] like Figure 2 and Figure 5As shown, in some embodiments, the reagent kit 51 includes an adjacent top cover 513 and a side plate 513. The top cover 513 forms the top wall of the reagent kit 51, and the side plate 513 forms the side wall of the reagent kit 51. The groove wall of the groove 511 separates the space within the groove 511 from the internal space of the reagent kit 51, and the bottom wall of the groove 511 connects the top cover 513 and one of the side plates 513. Both the top cover 512 and the side plate 513 have notches, and the notch of the top cover 512 forms the first opening 511a of the groove 511, and the notch of the side plate 513 forms the second opening 511b of the groove 511. The sample container 52 as a whole does not exceed the plane defined by the first opening 511a and the plane defined by the second opening 511b. This structure, which features notches in the top cover 513 and side panel 513 of the reagent kit and with the sample container 52 entirely located within the groove 511, can prevent unnecessary collisions and scratches between the sample container 52 within the groove 511 and other devices, thus better protecting the sample container 52.

[0036] like Figure 5 , Figure 8 and Figure 9 As shown, in some embodiments of the groove 511, the groove 511 is formed on a separate groove member 514, which defines the groove 511 and connects between the reagent kit top cover 513 and the reagent kit side plate 513. The groove member 514 can be a detachable structure that is disassembled and installed on the reagent kit 51, or it can be a non-detachable structure that is fixedly installed on the reagent kit 51. The two ends of the sample container 52 are connected between a pair of groove sidewalls of the groove member 514. Each pair of groove sidewalls of the groove member 514 is provided with mounting holes, one end of the sample container 52 passes through the mounting hole on one groove sidewall, and the other end of the sample container 52 passes through the mounting hole on the other groove sidewall. In alternative embodiments of the groove 511, the groove 511 can also be integrally formed with the reagent kit top cover 513 or the reagent kit side plate 513.

[0037] like Figure 2 and Figure 7As shown, in some embodiments of this application, the ultrasonic device 3 is used to emit ultrasonic waves into the sample container 52 within the groove 511 and act on the test liquid inside the sample container 52. Further, the ultrasonic waves emitted by the ultrasonic device 3 are used to break up blood cells in the test liquid within the blood oxygen testing channel of the sample container 52, releasing hemoglobin from the blood cells. The detection light emitted by the light-emitting device 4 can pass through the blood oxygen testing channel of the sample container 52 within the groove, and then the detection light emitted from the sample container 52 is received by an optical fiber. After receiving the detection light, the optical fiber guides the detection light to a spectrometer 6 connected to the optical fiber. The spectrometer 6 analyzes the intensity of the received detection light and converts it into an electrical signal, which is then transmitted to the analyzer host. The analyzer host analyzes this electrical signal to calculate blood oxygen saturation and other blood oxygen parameters. The analyzer host also outputs the blood oxygen saturation and other blood oxygen parameters of the test liquid. This blood gas analyzer can simultaneously measure blood gas parameters and blood oxygen parameters of the test liquid on a single analyzer host, enabling it to perform measurements of more parameters of the test liquid and output test results, thus offering enhanced functionality.

[0038] like Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments of this application, the main unit support 11 includes a main unit support side plate 112 forming the side wall of the main unit support 11 and a main unit support side plate 112 forming the top wall of the main unit support 11. The main unit support 11 also has a test card mounting position 11b on its exterior for mounting a test card assembly. The test card assembly is replaceably inserted into the test card mounting position 11b as a consumable, and the test card assembly has a blood gas testing channel inside. The reagent kit 51 has a test card mounting cavity 53 on its exterior. When the reagent kit 51 is inserted into the reagent kit chamber 11c inside the main unit support 11, the test card mounting cavity 53 protrudes from the position of the test card mounting position 11b. When the external test card assembly is inserted into the blood gas analyzer, the test card assembly is inserted into the test card mounting cavity 53 and connected to the reagent kit 51, wherein the blood gas testing channel inside the test card assembly can communicate with the communicating tubing inside the reagent kit 51.

[0039] like Figures 8 to 12As shown, in some embodiments, the sample container 52 includes a sample container body 521, the interior of which has a sample chamber for containing a sample. Both ends of the sample container body 521 are provided with liquid guide tubes 522 communicating with the sample chamber. One end of the liquid guide tube 522 communicates with the sample chamber, and the other end is located inside the reagent kit 51. In this embodiment, the blood oxygen testing channel includes the sample chamber of the sample container body 521 and the tubing of the liquid guide tube 522. The reagent kit 51 has a connecting tube that can communicate with the two liquid guide tubes 522 of the sample container 52. The reagent pack in the reagent kit 51 can provide test solution to the sample chamber inside the sample container body 521 through the connecting tube and the liquid guide tube 522.

[0040] like Figures 8 to 12 As shown, in some embodiments, flexible sleeves 523 are connected to both ends of the sample container body 521. The flexible sleeves 523 are used to connect the sample container body 521 to the reagent kit 51. A liquid guide tube 522 passes through the flexible sleeve 523. The flexible sleeve 523 refers to a sleeve that can undergo elastic deformation when subjected to a certain limit of external force, that is, it deforms when subjected to a certain limit of external force and can recover its deformation after the external force is removed. When the sample container body 521 is not moved, the flexible sleeve 523 can be fixedly connected to the sample container body 521 and the box wall of the reagent kit 51, so that the sample container body 521 is fixedly connected to the reagent kit 51. When the sample container body 521 is moved by external force, the flexible sleeve 523 allows the sample container body 521 and the liquid guide tube 522 to move through its own elastic deformation. The flexible sleeve 523 can prevent direct contact between the liquid guide tube 522 and the top cover 512 of the reagent kit. The flexible sleeve 523 can deform to a certain extent, maintaining a stable connection between the sample container 52 and the reagent kit 51 while allowing the sample container 52 and the liquid guide tube 522 to move within a limited range. This can minimize the resistance encountered by the liquid guide tube 522 and the sample container body 521 when they need to move, and prevent the liquid guide tube 522 and the reagent kit 51 from separating due to pressure on the sample container body 521.

[0041] like Figures 8 to 12As shown, in some embodiments, the sample container body 521 includes two parallel light-transmitting plates 5211 through which detection light can pass. The detection light is incident and emitted perpendicularly to the surface of the light-transmitting plate 511. The normal of the surface of the light-transmitting plate 5211 is inclined relative to both the reagent kit top cover 512 and the reagent kit side plate 513, and the reagent kit top cover 512 and the reagent kit side plate 513 are located on opposite sides of the light-transmitting plate 5211. In some embodiments, the normal of the surface of the light-transmitting plate 5211 is the same as the direction of movement of the light-emitting device 4. The bottom wall of the groove 511 is parallel to the normal of the surface of the light-transmitting plate 5211, and there is a gap between the bottom wall of the groove 511 and the sample container 52. This reduces the space occupied by the groove 511 on the reagent kit 51 without substantially affecting the movement of the ultrasound device 3 and the light-emitting device 4 into the groove 511. With the ultrasound device 3 and the light-emitting device 4 not in contact with the sample container 52, the ultrasound device 3 is located above the top wall of the reagent kit 51, and the light-emitting device 4 is located outside the side wall of the reagent kit 51.

[0042] like Figure 5 , Figure 9 and Figure 10 As shown, in some embodiments, the angle between the normal of the surface of the light-transmitting plate 5211 and the top cover 513 of the reagent kit is 30°-60°, and the angle between the normal of the surface of the light-transmitting plate 5211 and the side plate 513 of the reagent kit is 30°-60°. The normal of the surface of the light-transmitting plate 5211 is approximately parallel to the bottom wall of the groove 511. "Approximately parallel" can be understood as the acute angle between the normal of the surface of the light-transmitting plate 5211 and the bottom wall of the groove 511 being less than 10°. More preferably, the angle between the normal of the surface of the light-transmitting plate 5211 and the top cover 513 of the reagent kit is 45°, and the angle between the normal of the surface of the light-transmitting plate 5211 and the side plate 513 of the reagent kit is also 45°. This arrangement reduces the overall volume occupied by the ultrasound device 4 and the light-emitting device 3 while preventing the movement of the ultrasound device 4 and the light-emitting device 3 from affecting the internal structure of the reagent kit 51.

[0043] like Figures 8 to 12As shown, in some embodiments, the flexible cannula 523 includes a cannula body portion 5231 and a cannula connecting portion 5232. The cannula body portion 5231 is connected to the cannula connecting portion 5232, which is sleeved on the end of the sample container body 521. The cannula body portion 5231 is used to connect to the reagent kit 51. The inner wall surface of the cannula connecting portion 5232 contacts the outer wall surface of the sample container body 521 to fix the sample container body 521. Further, a liquid guide tube 522 passes through the internal channel of the cannula body portion 5231. The inner wall surface of the cannula body portion 5231 is not in contact with the outer wall surface of the liquid guide tube 522, so that the liquid guide tube 522 can move within the cannula body portion 5231. The cross-sectional dimension of the cannula body portion 5231 is smaller than the cross-sectional dimension of the cannula connecting portion 5232, and the axial length of the cannula body portion 5231 is greater than the axial length of the cannula connecting portion 5232. The sleeve connection portion 5232 can support the sleeve body portion 5231 to reduce the contact between the sleeve body portion 5231 and the liquid guide tube 522, thereby forming a space for the liquid guide tube 522 to move.

[0044] like Figures 8 to 12 As shown, in some embodiments, the flexible sleeve 523 further includes a sleeve limiting portion 5233, which and the sleeve connecting portion 5232 are respectively connected to the two axial ends of the sleeve body portion 5231; the cross-sectional dimension of the sleeve limiting portion 5233 is larger than the cross-sectional dimension of the sleeve body portion 5231. The sleeve limiting portion 5233 is used to limit the range of movement of the sleeve body portion 5231 along its axial direction, thereby preventing the flexible sleeve 523 from falling off the reagent kit 51. It can be understood that the side of the sleeve limiting portion 5233 facing the sleeve connecting portion 5232 is used to abut against the wall of the reagent kit 51.

[0045] like Figures 8 to 12 As shown, in some embodiments, the sample container body 521 is provided with a positioning hole 521a, which is used to cooperate with the positioning post in the light-emitting device 4 so that the sample container body 521 and the light-emitting device 4 can be aligned as much as possible. Here, "cooperate" means that the positioning post in the light-emitting device 4 can be inserted into the positioning hole 521a.

[0046] In one embodiment of this application, the testing process and principle of the blood gas analyzer comprising a sample container 52 and a reagent kit 51 integrated into a reagent kit assembly 5 are as follows: After the test card assembly and the reagent kit assembly 5 are installed in the main unit bracket 11, during the calibration process before testing, the delivery pump drives the calibration solution to first flow into the blood gas testing channel within the test card assembly for blood gas parameter calibration, then through the blood oxygen testing channel within the sample container 52, and finally back into the waste liquid bag inside the reagent kit 51. During the testing process after calibration, the test solution inside the syringe or capillary at the sampling needle port 133 is drawn into the connecting tubing within the reagent kit 51. The test solution first flows into the blood gas testing channel within the test card assembly for blood gas parameter measurement, then flows into the blood oxygen testing channel within the sample container 52 for blood oxygen parameter measurement, and finally back into the waste liquid bag inside the reagent kit 51. During the cleaning process after testing, the cleaning solution in reagent kit 51 flows back to the waste bag through the connecting tubing inside reagent kit 51, the blood gas testing channel in the test card, and the blood oxygen testing channel in sample container 52, completing the cleaning of all tubing and preparing for the next use. The detection electrodes in the test card assembly can measure parameters such as oxygen partial pressure (dissolved oxygen in blood), pH value, carbon dioxide partial pressure, and electrolyte concentration in the calibration solution or test solution, and transmit the blood gas parameter measurement results to the analyzer host; the blood oxygen measurement module can measure blood oxygen saturation (different from oxygen partial pressure) and other indicators in the test solution in sample container 52, and transmit the blood oxygen parameter measurement results to the analyzer host. It can be understood that the order in which the calibration solution or test solution enters the test card assembly for blood gas parameter measurement and enters the sample container 52 for blood oxygen parameter measurement can be reversed. The test solution can also enter the test card assembly and the sample container 52 through independent tubing to complete the blood gas parameter measurement and blood oxygen parameter measurement respectively.

[0047] During blood oxygen saturation measurement, on the one hand, the ultrasonic device 3 needs to transmit vibrations more effectively to the test liquid in the sample container 52 to fully break down blood cells in the test liquid, and on the other hand, the optical fiber needs to be as close to the sample container 52 as possible to better receive the detection light. Therefore, the ultrasonic device 3 should be in contact with the sample container 52 as much as possible during the blood oxygen saturation measurement process. On the other hand, to avoid the instability of the light intensity and optical path of the detection light entering the sample container 52, which could affect the accuracy of the blood oxygen measurement results, the light-emitting device 4 should also be in contact with the sample container 52 as much as possible. Therefore, the gap between the ultrasonic device 3 and the light-emitting device 4 during the test process needs to be designed to be very small, almost equal to the thickness of the sample container 52. In some related technologies, the sample container 52 is replaceably positioned between the ultrasonic device 3 and the light-emitting device 4. Because the gap can only be designed to be very small, the insertion and removal of the sample container 52 will cause wear on the surface of the sample container 52. The damage marks on the surface of the sample container 52 will scatter the light, affecting the accuracy and precision of the blood oxygen saturation measurement.

[0048] To address the aforementioned technical problems, this application further proposes a blood gas analyzer in which the entire reagent kit component 5 is used as a consumable and the ultrasound device and luminescence device are movable.

[0049] like Figure 13 and Figure 14 As shown, the sample container 52 has a first side and a second side arranged opposite to each other, and the ultrasonic device 3 and the light-emitting device 4 have a testing state and a separation state during the movement. Figure 13 This is a schematic diagram showing the positional relationship between the ultrasonic device 3 and the light-emitting device 4 and the sample container 52 when they are in the testing state. Figure 14 This diagram illustrates the positional relationship between the ultrasonic device 3 and the light-emitting device 4 and the sample container 52 when they are separated. When the ultrasonic device 3 and the light-emitting device 4 are in the testing state, the ultrasonic device 3 is in contact with the first side of the sample container 52, and the light-emitting device 4 is in contact with the second side of the sample container 52. When the ultrasonic device 3 and the light-emitting device 4 are separated, the ultrasonic device 3 is spaced apart from the first side of the sample container 52, and the light-emitting device 4 is spaced apart from the second side of the sample container 52. Figure 14 In this diagram, a three-dimensional coordinate system is established with the wide side of the mounting bracket 21 as the X-axis, the long side of the mounting bracket 21 as the Y-axis, and the height of the mounting bracket 21 as the Z-axis. In this system, direction a represents the insertion direction of the reagent kit component 5, which is in the same direction as the opposite of the X-axis. The removal direction of the reagent kit component 5 is in the same direction as the positive X-axis. Direction b represents the motion direction of the ultrasound device 3 as it moves away from the sample container 52 in a straight line. Direction c represents the motion direction of the luminescent device 4 as it moves away from the sample container 52 in a straight line. Directions c and b are on the same straight line and in opposite directions, and both directions c and b are perpendicular to direction a.

[0050] The embodiment of this application employs a movable structure design for the ultrasonic device 3 and the light-emitting device 4. Before the sample container 52 needs to be loaded or removed, the ultrasonic device 3 and the light-emitting device 4 are moved to a separated state. At this time, the ultrasonic device 3 and the light-emitting device 4 will not obstruct the loading or removal of the sample container 52. The sample container 52 will not be damaged due to friction caused by contact with the ultrasonic device 3 or the light-emitting device 4 during the assembly and disassembly process, thereby avoiding the scattering of light by the surface wear of the sample container 52, which would affect the measurement accuracy of blood oxygen saturation and other blood oxygen parameters. During the measurement of blood oxygen saturation and other blood oxygen parameters, the ultrasonic device 3 and the light-emitting device 4 are moved to contact the sample container 52 under external force. The ultrasonic device 3 contacts the sample container 52 from the first side, and the light-emitting device 4 contacts the sample container 52 from the second side. At this time, the gap between the ultrasonic device 3 and the light-emitting device 4 is equal to or almost equal to the thickness of the sample container 52. When the ultrasonic device 3 and the sample container 52 are in contact, the ultrasonic device 3 can effectively transmit vibrations to the test liquid inside the sample container 52, improving the disruption effect of blood cells in the test liquid. The optical fiber, being very close to the sample container 52, can better receive the detection light transmitted through the sample container 52. Furthermore, with both the ultrasonic device 3 and the light-emitting device 4 in contact with the sample container 52, even if the position of the sample container 52 itself deviates slightly, the relative positional relationship between the ultrasonic device 3, the light-emitting device 4, and the sample container 52 remains fixed or substantially fixed. This ensures that the measurement accuracy and precision are kept as consistent as possible for each measurement. Based on the replaceable use of the sample container 52 as a consumable, this application reduces surface wear on the sample container 52 by making the ultrasonic device 3 and the light-emitting device 4 movable structures, while ensuring sufficient contact between the ultrasonic device 3 and the sample container 52, and between the light-emitting device 4 and the sample container 52 during testing, thus guaranteeing the consistency of blood oxygen parameter measurement results.

[0051] like Figure 13 and Figure 14 As shown, in some embodiments, the ultrasonic device 3 and the light-emitting device 4 can synchronously approach or move away from the sample container 52 at the test chamber of the sample container under external force. That is, the movement of the ultrasonic device 3 and the movement of the light-emitting device 4 are synchronized. When the ultrasonic device 3 moves to a position that contacts the first side of the sample container 52, the light-emitting device 4 simultaneously moves to a position that contacts the second side of the sample container 52. Since the sample container 52 is small in size and connected to the reagent kit 51, the simultaneous contact of the ultrasonic device 3 and the light-emitting device 4 with the sample container 52 can avoid the problem of excessive displacement and local damage to the sample container 52 caused by one of the ultrasonic device 3 and the light-emitting device 4 contacting the sample container 52 first.

[0052] In an alternative implementation, the ultrasonic device 3 and the light-emitting device 4 can approach or move away from the sample container 52 at the sample container test chamber in stages under external force. For example, during the process of the ultrasonic device 3 and the light-emitting device 4 approaching the sample container 52, the ultrasonic device 3 first approaches and contacts the first side of the sample container 52 under external force, and then the light-emitting device 4 approaches and contacts the second side of the sample container 52 under external force. Of course, the movement sequence of the ultrasonic device 3 and the light-emitting device 4 can also be reversed. In this case, it is necessary to precisely control the movement distance of the ultrasonic device 3 and the light-emitting device 4 to avoid the ultrasonic device 3 and the light-emitting device 4 from colliding with the sample container 52 or having an excessive gap with the sample container 52. The control precision requirements are relatively high, and the risk of damage to the sample container 52 is also greater. The ultrasonic device 3 and the light-emitting device 4 can be driven by a drive motor, or they can be driven manually.

[0053] like Figure 13 and Figure 14 As shown, in some embodiments, the ultrasonic device 3 faces the first side of the sample container 52, and the light-emitting device 4 faces the second side of the sample container 52. Driven by an external force, the ultrasonic device 3 moves in a straight line, approaching or moving away from the sample container 52 at the sample container's test chamber. The light-emitting device 4 also moves in a straight line, approaching or moving away from the sample container 52 at the sample container's test chamber. Further, the ultrasonic device 3 and the light-emitting device 4 move in the same straight line. When both the ultrasonic device 3 and the light-emitting device 4 move towards the sample container 52, their directions of movement are opposite. With this arrangement, when both the ultrasonic device 3 and the light-emitting device 4 reach a position in contact with the sample container 52, the forces on both sides of the sample container 52 are opposite and more evenly distributed, thereby preventing the sample container 52 from deflecting or breaking when clamped by the ultrasonic device 3 and the light-emitting device 4. In alternative embodiments, the ultrasonic device 3 and the light-emitting device 4 may not always be located on opposite sides of the sample container test chamber, but can move to opposite sides of the sample container test chamber by means of rotation, etc.; for example, the ultrasonic device 3 is connected to a rotatable swing arm, and the light-emitting device 4 is connected to another rotatable swing arm. During the swinging process, the ultrasonic device 3 can rotate to one side of the sample container 52 or rotate out from one side of the sample container 52, and the light-emitting device 4 can rotate to the other side of the sample container 52 or rotate out from the other side of the sample container 52. It is understood here that the operation mode of the ultrasonic device 3 and the light-emitting device 4 is not limited to the above-mentioned linear or rotational movement mode, but can also be a combination of linear and rotational movement. Any movement mode in which the ultrasonic device 3 and the light-emitting device 4 can move to both sides of the sample container 52 and move away from both sides of the sample container 52 is within the protection scope of this application.

[0054] like Figure 3 , Figure 15 and Figure 16 As shown, in some embodiments, the top plate 111 of the main unit bracket has a top opening, and the side plate 112 of the main unit bracket has a side opening. The mounting bracket 21 includes a first side plate 21a and a second side plate 21b that are adjacent and arranged at an angle. The first side plate 21a is aligned with the top plate 111 of the main unit bracket, and the second side plate 21b is aligned with the side plate 112 of the main unit bracket. The first side plate 21a has a first side bracket opening that is aligned with and communicates with the top opening 111a, and the second side plate 21b has a second side bracket opening that is aligned with and communicates with the side opening 112a. During movement, the ultrasonic device 3 can extend into or out of the groove 511 through the first side bracket opening and the top opening 111a; the light-emitting device 4 can extend into or out of the groove 511 through the second side bracket opening and the side opening 112a during movement.

[0055] like Figure 7 , Figure 15 and Figure 16 As shown, in some embodiments of this application, the drive actuator 2 includes a mounting bracket 21 and a drive motor 22. The ultrasonic device 3 and the light-emitting device 4 are driven by the same drive motor 22 to move the sample container 52 near or away from the sample container test chamber. Using only a single drive motor 22 to simultaneously drive both the ultrasonic device 3 and the light-emitting device 4 reduces the number of drive motors 22, achieving a compact design of the overall structure. Furthermore, the simultaneous driving of both the ultrasonic device 3 and the light-emitting device 4 by a single drive motor 22 also simplifies the synchronous start and stop of the ultrasonic device 3 and the light-emitting device 4. In an alternative embodiment, two drive motors can be mounted on the mounting bracket 21. The ultrasonic device 3 is driven by one drive motor to move the sample container 52 near or away from the sample container test chamber, and the light-emitting device 4 is driven by the other drive motor to move the sample container 52 near or away from the sample container test chamber.

[0056] like Figure 7 , Figure 15 and Figure 16As shown, in some embodiments of this application, the mounting bracket 21 is fixed to the outside of the main unit bracket 11, and the mounting bracket 21 has a semi-open cavity structure. Further, the mounting bracket 21 includes two half-shell brackets, which enclose the mounting bracket 21, and the cavity structure is located between the two half-shell brackets. In some embodiments, the drive motor 22 is mounted at one end of the mounting bracket 21, and the ultrasonic device 3 and the light-emitting device 4 are both partially or entirely located within the cavity structure enclosed by the mounting bracket 21. The ultrasonic device 3 and the light-emitting device 4 are slidably connected to the mounting bracket 21 along the same straight line direction, and can slide in opposite directions on the mounting bracket 21 under the drive of the drive motor 22. With this configuration, the mounting bracket 21 with the cavity structure can constrain the ultrasonic device 3 and the light-emitting device 4 within itself. Compared to using only a single plate for the ultrasonic device 3 and the light-emitting device 4 to slide on, this improves the stability of the ultrasonic device 3 and the light-emitting device 4 during the sliding process, thereby improving the positional movement accuracy of the ultrasonic device 3 and the light-emitting device 4.

[0057] In some embodiments, the ultrasonic device 3 includes an ultrasonic mounting bracket and an ultrasonic transducer fixed on the ultrasonic mounting bracket. The ultrasonic mounting bracket is slidably disposed on the mounting bracket, and the ultrasonic transducer is used to emit ultrasonic waves. The light-emitting device 4 includes a light source mounting bracket and a light-emitting component fixed on the light source mounting bracket. The light source mounting bracket is slidably disposed on the mounting bracket 21 and slidably connected to the mounting bracket 21, and the light-emitting component is used to emit detection light.

[0058] In some embodiments, the drive actuator 2 includes a main drive assembly and a synchronous drive assembly. The main drive assembly is driven between the drive motor 22 and the ultrasonic device 3, or between the drive motor 22 and the light-emitting device 4, and the synchronous drive assembly is driven between the ultrasonic device 3 and the light-emitting device 4. The synchronous drive assembly is located within the cavity structure of the mounting bracket 21. When one of the ultrasonic device 3 and the light-emitting device 4 slides under the drive of the drive motor 22, the synchronous drive assembly drives the other of the ultrasonic device 3 and the light-emitting device 4 to slide in the opposite direction. This arrangement allows the synchronous drive assembly to enable the ultrasonic device 3 and the light-emitting device 4 to move synchronously, and to simultaneously contact the sample container 52. In an alternative embodiment, the drive actuator 2 includes a main drive assembly, with both the ultrasonic device 3 and the light-emitting device 4 directly driven to the main drive assembly, and the drive motor simultaneously drives the ultrasonic device 3 and the light-emitting device 4 to slide in opposite directions via the main drive assembly.

[0059] In some alternative embodiments, the output shaft of the drive motor 22 is connected to a main drive assembly, which includes a drive gear. The ultrasonic device 3 and the light-emitting device 4 are both connected to the drive gear via gear meshing. The ultrasonic device 3 and the light-emitting device 4 are respectively meshed at the two ends of the drive gear that are furthest apart, so that the ultrasonic device 3 and the light-emitting device 4 can move in opposite directions.

[0060] In some alternative embodiments, the synchronous transmission assembly includes a driven transmission gear, with the ultrasonic device 3 and the light-emitting device 4 meshing at the farthest ends of the driven transmission gear, enabling the ultrasonic device 3 and the light-emitting device 4 to move in opposite directions. The drive motor 22 drives one of the ultrasonic device 3 and the light-emitting device 4 via the main transmission assembly, and drives the other of the ultrasonic device 3 and the light-emitting device 4 via the driven transmission gear, thereby achieving synchronous movement of the ultrasonic device 3 and the light-emitting device 4.

[0061] This blood gas analyzer integrates a reagent kit assembly 5 (containing a sample container 52) and a test card assembly into the analyzer host. When measuring blood gas parameters of a sample, the detection electrodes in the test card assembly can measure parameters such as oxygen partial pressure (dissolved oxygen in the blood), pH value, carbon dioxide partial pressure, and electrolyte concentration, and output electrical signals to the analyzer host. When measuring blood oxygenation parameters, the sample is introduced into the sample container 52 through the reagent kit assembly 5. The ultrasonic device 3 and the light-emitting device 4 move to contact both sides of the sample container 52. The ultrasonic waves emitted by the ultrasonic device 3 act on the sample inside the sample container 52, and the detection light emitted by the light-emitting device 4 passes through the sample container 52 at the test chamber and then illuminates the optical fiber inside the ultrasonic device 3. After receiving the detection light, the optical fiber guides it to a spectrometer 6 connected to the optical fiber. The spectrometer 6 analyzes the intensity of the received detection light and converts it into an electrical signal, which is transmitted to the analyzer host. The analyzer host analyzes this electrical signal to calculate blood oxygenation parameters such as blood oxygen saturation. The analyzer host also outputs the blood gas measurement parameters and blood oxygenation measurement parameters of the sample. When reagent kit component 5 is used in conjunction with ultrasound device 3 and light-emitting device 4 to measure blood oxygen parameters, ultrasound device 3 and light-emitting device 4 have separate and testing states during movement. When ultrasound device 3 and light-emitting device 4 are in the separated state, both ultrasound device 3 and light-emitting device 4 are completely outside the groove 511, so that reagent kit component 5 can be normally placed and removed without interference from ultrasound device 3 and light-emitting device 4. When ultrasound device 3 and light-emitting device 4 are in the testing state, ultrasound device 3 and light-emitting device 4 are partially located inside the groove 511 and respectively in contact with both sides of sample container 52 to perform blood oxygen parameter measurement.

[0062] like Figure 2 , Figure 15 and Figure 16 As shown, the spectrometer 6 is fixedly connected to the ultrasonic device 3 via the spectrometer mounting bracket 61. In actual use, not only will the optical fiber move with the ultrasonic device 3, but the spectrometer 6 will also move synchronously with the ultrasonic device 3. This ensures that the optical fiber can move synchronously with the spectrometer 6 and remain relatively stationary. Therefore, it can improve or eliminate the deformation and stress problems of the optical fiber and ensure that the optical fiber has a long service life.

[0063] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
