[0002] Blood gas analysis measures parameters such as pH, partial pressure of carbon dioxide (PCO2), and partial pressure of oxygen (PO2) in the blood. It is a crucial tool for assessing acid-base imbalance, hypoxia, and the degree of hypoxia. Blood gas analysis technology also plays a vital role in the diagnosis and treatment of acute respiratory failure, surgical procedures, and in resuscitation and monitoring.

[0003] Existing blood gas testing is mainly performed using blood gas analyzers. The blood gas testing process of blood gas analyzers generally involves calibration before testing. The equipment first extracts calibration solution from the reagent pack and applies it to the electrode position of the test card for calibration, and then extracts a blood sample from the blood collection device and applies it to the electrode position of the test card for testing.

[0004] While existing blood gas analyzers can detect the content of various components in a sample, their large size and bulky design, along with the internal heater, calibration solution tubing, and blood sample tubing, make them inconvenient to carry. Therefore, a blood sample must be collected and transported to the blood gas analyzer before testing, resulting in a long testing interval, extending the detection cycle, and increasing the time required for disease diagnosis.

[0040] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0041] This invention provides a blood gas testing reagent card, such as Figures 1-4As shown, the device includes a detection box 10, a calibration solution module 20, and an electrode reaction card 30. The detection box 10 has a reaction chamber 11, a calibration solution channel 12, and a sample inlet channel 13 inside. Both the calibration solution channel 12 and the sample inlet channel 13 are connected to the reaction chamber 11. The surface of the detection box 10 has a sample inlet 14, which is connected to the calibration solution channel 12. The sample inlet 14 is used to connect to a sample feeding device to feed blood samples into the sample inlet 14. The calibration solution module 20 is located inside the detection box 10 and is used to feed calibration solution into the calibration solution channel 12. The electrode reaction card 30 is installed in the reaction chamber 11 and is used to receive blood samples and calibration solution through the reaction zone, and to heat the received blood samples and calibration solution to detect the content of each corresponding component in the sample.

[0042] Specifically, the blood gas test kit comprises a test box 10, a calibration solution module 20, and an electrode reaction card 30. The test box 10 contains a reaction chamber 11, a calibration solution channel 12, and a sample inlet channel 13, both of which are connected to the reaction chamber 11. The calibration solution module 20 is located inside the test box 10, and the electrode reaction card 30 is installed in the reaction chamber 11. During blood gas testing, calibration solution is supplied to the calibration solution channel 12 through the calibration solution module 20. The calibration solution flows along the calibration solution channel 12 to the reaction chamber 11 and contacts the reaction area of ​​the electrode reaction card 30 within the reaction chamber 11, calibrating the electrode reaction card 30. The surface of the test box 10 is decorated with... The device is equipped with an inlet 14, which can be connected to a sample feeding device. The sample feeding device feeds blood samples into the inlet 14. The samples enter the reaction chamber 11 through the sample inlet channel 13 and come into contact with the reaction area of ​​the electrode reaction card 30 in the reaction chamber 11. This allows for the detection of the content of each corresponding component in the sample. By setting up the electrode reaction card 30, the calibration liquid module 20, the calibration liquid channel 12, and the sample inlet channel 13, the blood sample detection process can be concentrated in the detection box 10, thereby effectively reducing the size of the blood gas detection device, making the blood gas detection device easy to carry, and facilitating the detection of the content of each corresponding component in the sample, thus improving the detection efficiency of the content of each corresponding component in the sample.

[0043] Understandably, the detection box 10 can be a box structure of any shape, either integrally formed or spliced ​​from multiple shells.

[0044] Understandably, the length and cross-sectional area of ​​the calibration solution channel 12 and the sample inlet channel 13 can be adjusted according to the amount of calibration solution and sample volume.

[0045] Understandably, the sample feeding device can be any device capable of feeding blood samples into the inlet 14, and the shape and size of the inlet 14 can be adjusted according to the structural adaptability of the sample feeding device.

[0046] In this embodiment, the electrode reaction card 30 substrate material includes, but is not limited to, PET, PC, PVC, PP and other plastic flexible board materials, which can be PCB substrate (resin), aluminum substrate, ceramic substrate and other wiring circuit boards.

[0047] In this embodiment, the electrode reaction card 30 is equipped with a specific microsensor. After calibration with a calibration solution, the microsensor heats the blood sample in contact with the reaction area of ​​the electrode reaction card 30 at a specific temperature, causing the blood sample to undergo an equilibrium reaction. The electrode reaction card 30 exhibits different electrical characteristics in the electrode area. The electrode reaction card 30 is then connected to various measuring devices to test the electrical characteristics of the electrode area circuit. Through algorithm compensation and standard solution experimental correction, the content of each corresponding component in the blood sample can be measured. The measurement is not limited to the following sample parameters: pO2, pH, pCO2 values, electrolyte concentrations such as Na+, K+, Cl-, Ca+, GLU (blood glucose), Crea (creatinine), Bun (urea nitrogen), Lac (lactic acid), etc. The electrode reaction card 30 has the characteristics of integration and miniaturization.

[0048] Understandably, the calibration fluid module 20 can be any device that can hold a blood sample, such as a syringe or a miniature injection pump.

[0049] In this embodiment, as Figure 2 , 4 As shown in Figure 7, the test box 10 includes a lower shell 15 and an elastic sealing sheet 16. One side of the elastic sealing sheet 16 is attached to the lower shell 15, and the calibration liquid flow channel 12 and the sample inlet flow channel 13 are disposed between the elastic sealing sheet 16 and the lower shell 15. Specifically, due to the elastic effect of the elastic sealing sheet 16, its contact surface with the lower shell 15 can remain stably attached, thereby maintaining the sealing of the calibration liquid flow channel 12 and the sample inlet flow channel 13, effectively preventing the calibration liquid and blood sample from leaking out of the calibration liquid flow channel and the sample inlet flow channel 13.

[0050] In this embodiment, the elastic sealing sheet 16 includes, but is not limited to, diaphragm silicone, rubber, soft plastic, double-sided sealing adhesive, etc.

[0051] Understandably, the reaction chamber 11 can be located inside the lower shell 15, and the sample inlet 14 can be located in the elastic sealing sheet 16.

[0052] In this embodiment, as Figures 1-5As shown in Figures 7 and 9, the detection box 10 also includes an upper shell 17, which is attached to the other side of the elastic sealing sheet 16 and fixedly connected to the lower shell 15. The reaction chamber 11 is disposed between the upper shell 17 and the lower shell 15. The elastic sealing sheet 16 is also provided with a liquid inlet port 161, which is connected to the calibration liquid channel 12 and the sample inlet channel 13. A liquid inlet channel 171 is provided between the upper shell 17 and the elastic sealing sheet 16. One end of the liquid inlet channel 171 is connected to the liquid inlet port 161, and the other end of the liquid inlet channel 171 is connected to the reaction area of ​​the electrode reaction card 30.

[0053] Specifically, with the above settings, after the calibration solution and sample solution enter the calibration solution flow channel 12 and the sample injection flow channel 13, they both need to enter the inlet connection channel 171 through the inlet connection port 161, and then enter the reaction area of ​​the electrode reaction card 30 through the inlet connection channel 171. Since the calibration solution and sample solution share the inlet connection channel 171 to enter the reaction area of ​​the electrode reaction card 30, the flow direction of the sample solution entering later is the same as that of the calibration solution entering earlier, so as to facilitate the sample solution to squeeze the calibration solution out of the reaction area of ​​the electrode reaction card 30. At the same time, after the sample solution enters the reaction area of ​​the electrode reaction card 30, it will occupy the inlet connection channel 171, thereby preventing the residual calibration solution from entering the reaction area of ​​the electrode reaction card 30, so as to improve the detection accuracy of the sample.

[0054] Meanwhile, since the calibration liquid flow channel 12 and the sample inlet flow channel 13 are located between the elastic sealing sheet 16 and the lower shell 15, and the liquid inlet connecting channel 171 is located between the elastic sealing sheet 16 and the upper shell 17, the calibration liquid flow channel 12 and the sample inlet flow channel 13 and the liquid inlet connecting channel 171 form an upper and lower layered structure, which makes the calibration liquid and sample liquid need to overcome gravity to enter the liquid inlet connecting channel 171, so as to facilitate the control of the amount of calibration liquid and sample liquid entering the reaction zone of the electrode reaction card 30.

[0055] In this embodiment, the elastic sealing sheet 16 extends into the reaction chamber 11 and fits against the electrode reaction card 30. The elastic sealing sheet 16 is provided with a reaction port 162, which is located on one side of the reaction area of ​​the electrode reaction card 30. One end of the reaction port 162 is connected to the liquid inlet communication channel 171. The calibration solution and sample solution will enter the reaction port 162 from the liquid inlet communication channel 171 and contact the reaction area of ​​the electrode reaction card 30.

[0056] In this embodiment, the cross-sectional areas of the calibration solution channel 12 and the sample inlet channel 13 are larger than the cross-sectional area of ​​the reaction port 162. This is to prevent the formation of air bubbles after the calibration solution and sample solution enter the reaction port 162.

[0057] In this embodiment, a waste liquid chamber 151 is also provided between the elastic sealing sheet 16 and the lower shell 15, and the waste liquid chamber 151 is connected to the reaction area of ​​the electrode reaction card 30. Specifically, the sample liquid can discharge the calibration liquid from the liquid inlet communication channel 171 and the reaction area of ​​the electrode reaction card 30 to the waste liquid chamber 151 to collect the waste liquid and avoid pollution from waste liquid discharge.

[0058] In this embodiment, as Figure 2 and 9 As shown, the elastic sealing sheet 16 is also provided with a waste liquid connection port 163, which is connected to the waste liquid chamber 151. A waste liquid connection channel 172 is also provided between the elastic sealing sheet 16 and the upper shell 17. One end of the waste liquid connection channel 172 is connected to the waste liquid connection port 163, and the other end of the waste liquid connection channel 172 is connected to the reaction area of ​​the electrode reaction card 30. Specifically, after the sample liquid is squeezed into the waste liquid connection channel 172 in the reaction area of ​​the electrode reaction card 30, the waste liquid will enter the waste liquid chamber 151 through the waste liquid connection port 163. Since the waste liquid chamber 151 is located between the elastic sealing sheet 16 and the lower shell 15, and the waste liquid connection channel 172 is located between the elastic sealing sheet 16 and the upper shell 17, the waste liquid connection channel 172 and the waste liquid chamber 151 form an upper and lower layered structure, thereby preventing the waste liquid in the waste liquid chamber 151 from flowing back to the reaction area of ​​the electrode reaction card 30 through the waste liquid connection channel 172.

[0059] In this embodiment, the waste liquid communication channel 172 is connected to the other end of the reaction port 162.

[0060] In this embodiment, the fit between the elastic sealing sheet 16 and the upper shell 17 ensures a stable seal between the liquid inlet channel 171 and the waste liquid channel 172.

[0061] In this embodiment, as Figures 1-2 As shown in Figures 4 and 7-8, the sample inlet 14 is located on the upper shell 17. The elastic sealing sheet 16 also has a sample inlet connection port 164. The sample inlet connection port 164 is located on one side of the sample inlet 14 and communicates with the sample inlet channel 13. A check valve 165 is fixed to the side wall of the sample inlet connection port 164. The check valve 165 is elastically connected to the side wall of the sample inlet connection port 164 and is located on one side of the sample inlet 14. The check valve 165 is used to fit against the upper shell 17 and block the sample inlet 14. Specifically, after the sample feeding device is connected to the sample inlet 14, the sample liquid drives the check valve 165 to open the sample inlet 14, so that the sample liquid enters the sample inlet channel 13 through the sample inlet connection port 164, realizing the feeding of the sample liquid. After the sample liquid feeding stops, the check valve 165 blocks the sample inlet 14, thereby preventing the sample liquid from flowing back.

[0062] In this embodiment, an exhaust chamber 173 is also provided between the elastic sealing sheet 16 and the upper shell 17. The elastic sealing sheet 16 is also provided with a first exhaust port 166, which is connected to the exhaust chamber 173 and the waste liquid chamber 151. The upper shell 17 is provided with a second exhaust port 174, which is connected to the exhaust chamber 173. Specifically, after the calibration liquid and sample liquid are introduced into the calibration liquid flow channel 12 and the sample inlet flow channel 13, they will drive the gas inside the detection box 10 from the first exhaust port 166 into the exhaust chamber 173, and finally discharge it from the second exhaust port 174, thereby facilitating the supply of calibration liquid and sample liquid. At the same time, when the waste liquid chamber 151 is filled with waste liquid, the waste liquid can also enter the exhaust chamber 173 through the first exhaust port 166, and be further contained by the exhaust chamber 173.

[0063] In this embodiment, to facilitate the sample solution entering the inlet communication channel 171 in the same flow direction as the calibration solution, such as... Figure 2 and 4 As shown in Figure 5, the end of the calibration liquid flow channel 12 is connected to the end of the sample inlet flow channel 13. Both the calibration liquid and the sample liquid are connected to the inlet port 161 through the connection between the calibration liquid flow channel 12 and the sample inlet flow channel 13. When the calibration liquid is introduced into the calibration liquid flow channel 12, the inlet port 14 is normally closed due to the sealing of the check valve 165, which prevents the gas in the sample inlet flow channel 13 from escaping from the inlet port 14. However, the gas on one side of the inlet inlet connection channel 171 can be discharged through the second exhaust port 174, making the internal air pressure of the sample inlet flow channel 13 greater than the air pressure on one side of the inlet inlet connection channel 171. As a result, when the calibration liquid flows to the connection between the calibration liquid flow channel 12 and the sample inlet flow channel 13, it will flow towards the inlet inlet connection channel 171 under the action of the internal air pressure of the sample inlet flow channel 13, thereby preventing the calibration liquid from entering the sample inlet flow channel 13.

[0064] In this embodiment, as Figure 2 and 4 As shown, the sidewall of the waste liquid chamber 151 is fixed with several spacer bars 152, which divide the waste liquid chamber 151 into a continuous curved waste liquid flow channel 153. The waste liquid connection port 163 is located on one side of the end of the waste liquid flow channel 153. Specifically, after the waste liquid enters the waste liquid chamber 151 through the waste liquid connection port 163, it will flow along the extension direction of the waste liquid flow channel 153, thereby driving the gas in the waste liquid chamber 151 to flow along the waste liquid flow channel 153. Finally, it enters the exhaust chamber 173 from the first exhaust port 166 and is finally discharged from the second exhaust port 174. This prevents the gas in the waste liquid chamber 151 from flowing back to the reaction area of ​​the electrode reaction card 30 from the waste liquid connection port 163 under the pressure of the waste liquid, which would affect the detection of the sample.

[0065] In this embodiment, the first exhaust port 166 is located on one side of the tail end of the waste liquid flow channel 153.

[0066] In this embodiment, further, as Figure 2 As shown, each spacer 152 has a guide protrusion 1521 at its end. The guide protrusion 1521 faces the corner of the waste liquid flow channel 153. The guide protrusion 1521 can guide the waste liquid to the corner of the waste liquid flow channel 153 so that the waste liquid fills each corner of the waste liquid flow channel 153.

[0067] In this embodiment, as Figure 2 , 4 As shown in Figure 7, the lower shell 15 is provided with a liquid inlet 154, which is connected to the calibration liquid flow channel 12. The elastic sealing sheet 16 has an installation port 167 opposite to the liquid inlet 154. The calibration liquid module 20 includes a calibration liquid bag 21 and an installation plate 22 fixed to the periphery of the calibration liquid bag 21. The calibration liquid bag 21 is used to store the calibration liquid. The calibration liquid bag 21 is located at the installation port 167 and extends to the liquid inlet 154. The installation plate 22 is in contact with the elastic sealing sheet 16. Specifically, the calibration liquid can enter the liquid inlet 154 through the calibration liquid bag 21, and then enter the calibration liquid flow channel 12 through the liquid inlet 154 to realize the supply of calibration liquid. The installation plate 22 can realize the installation of the calibration liquid module 20 on the elastic sealing sheet 16. At the same time, by contacting the elastic sealing sheet 16, the liquid inlet 154 can be effectively sealed to prevent the calibration liquid from escaping from the liquid inlet 154.

[0068] In this embodiment, the calibration liquid module 20 is further formed by sealing two calibration liquid films that are recessed inward from the middle.

[0069] In this embodiment, as Figure 2 , 4 As shown in Figure 7, a puncture unit 155 is fixed to the side wall of the liquid inlet tank 154. The puncture unit 155 extends towards the calibration liquid package 21. The calibration liquid package 21 can be punctured by pressing the puncture unit 155. Specifically, with the puncture unit 155, when supplying calibration liquid, it is only necessary to press the calibration liquid package 21 to puncture the calibration liquid package 21, allowing the calibration liquid to flow from the calibration liquid package 21 to the liquid inlet tank 154, thus facilitating sample testing.

[0070] In this embodiment, the puncture unit 155 is further defined as a needle.

[0071] The specific working principle of this invention is as follows: When detecting the content of each corresponding component in a sample, firstly, by pressing the calibration liquid pack 21, the puncture unit 155 punctures the calibration liquid pack 21. The calibration liquid in the calibration liquid pack 21 flows to the inlet tank 154, and then flows through the inlet tank 154 to the calibration liquid channel 12. It then enters the upper inlet channel 171 through the inlet port 161, and finally enters the reaction port 162, contacting the reaction area of ​​the electrode reaction plate to calibrate the electrode reaction plate. After the calibration of the electrode reaction plate is completed, the... Blood samples are supplied to the sample inlet 14 through the sample inlet channel 13. The sample liquid enters the upper liquid inlet channel 171 through the liquid inlet connector 161, and finally enters the reaction port 162, where it contacts the reaction area of ​​the electrode reaction plate. Under the heating of the electrode reaction plate, the content of each corresponding component in the sample is detected. During the process of the sample liquid entering the reaction port 162, it will carry the calibration liquid at the reaction port 162 into the waste liquid connector channel 172, and finally enter the waste liquid channel 153 from the waste liquid connector 163 to achieve waste liquid collection.

[0072] The specific embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. Any other corresponding changes and modifications made in accordance with the technical concept of the present invention should be included within the scope of protection of the claims of the present invention.
