Abstract
Description
Technical Field
[0001] This utility model specifically relates to an electrolyte analyzer with urine sample testing function. Background Technology
[0002] Electrolyte analyzers are indispensable in clinical testing. They primarily measure the osmotic pressure balance in human blood and body fluids, providing strong evidence for clinical diagnosis. Currently, electrolyte analyzers commonly use the ion-selective electrode method to measure the concentration of electrolyte ions in samples, a method that is highly efficient and accurate.
[0003] However, traditional electrolyte analyzers are relatively limited in function and cannot effectively measure urine samples, failing to meet the clinical needs for testing multiple sample types (especially urine samples). Utility Model Content
[0004] The purpose of this invention is to provide an electrolyte analyzer with urine sample testing function to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an electrolyte analyzer with urine sample determination function, comprising a housing, a control area, a sample inlet area, and a sample inlet assembly. The control area is located on the upper part of the housing, the sample inlet area is located on the lower right side of the housing, and the other side of the lower part of the housing is a reagent placement area. The reagents in the reagent placement area enter the housing through the sample inlet area via the sample inlet assembly for urine sample determination.
[0006] Preferably, the sample injection assembly includes a sample injection disk disposed on the sample injection area, the surface of the sample injection disk having a placement groove for inserting the sample to be tested, and a drive motor for driving the sample injection disk to rotate is disposed at the bottom of the sample injection disk.
[0007] Preferably, the housing is provided with a sample inlet arm, and the housing is also provided with a first motor and a second motor for controlling the horizontal and vertical movement of the sample inlet arm, and the sample inlet arm is provided with a sample inlet needle.
[0008] Preferably, the injection needle is provided with a tubing, the other end of which is connected to a power pump. The power pump is located inside the housing, and the other end of the power pump is connected to a bubble detector via a tubing.
[0009] Preferably, an electrode assembly is also provided inside the housing, and the electrode assembly is connected to the injection needle through a pipeline, and a bubble detection sensor is also provided on the pipeline between the electrode assembly and the injection needle.

[0011] Preferably, a solenoid valve assembly is provided inside the housing, and the solenoid valve assembly is arranged sequentially along the flow direction of the reagent.
[0012] The technical effects and advantages of this utility model are as follows: This electrolyte analyzer with urine sample testing function not only retains the accurate measurement capabilities of traditional electrolyte analyzers but also significantly enhances its functionality, particularly by adding urine sample testing capabilities. This further broadens its application scope in the clinical field. Through the sample introduction unit and components, accurate urine sample introduction and measurement are ensured, effectively avoiding measurement errors caused by improper sample processing, thus significantly improving the accuracy and reliability of the measurement. To achieve accurate detection of urine samples, the built-in pump and sample introduction components work together to dynamically and automatically dilute the sample at a ratio of 1:10 to 1:2, or the operator can dilute it according to a user-defined preset ratio before measurement, ensuring optimal sensitivity and accuracy during the measurement process. The use of a power pump and solenoid valve control accurately controls the sample intake and dilution process, effectively avoiding measurement errors caused by improper sample processing, significantly enhancing its application value and practicality in the clinical field.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0019] To ensure accurate urine sample introduction and measurement, refer to Figure 1 , Figure 2 and Figure 3As shown, the instrument includes a housing 1, a control area 2, a sample injection area 3, and a sample injection assembly. The control area 2 is located on the upper part of the housing 1, and the sample injection area 3 is located on the lower right side of the housing 1. The other side of the lower part of the housing 1 is a reagent placement area. The reagents in the reagent placement area enter the housing 1 through the sample injection area 3 via the sample injection assembly for urine sample testing. It retains the accurate measurement capability of traditional electrolyte analyzers and significantly enhances its functionality, especially by adding a urine sample testing function, further broadening its application scope in the clinical field. Through the sample injection section and assembly, the accurate introduction and measurement of urine samples can be ensured, effectively avoiding measurement errors caused by improper sample processing, thereby significantly improving the accuracy and reliability of the measurement. In order to achieve accurate detection of urine samples, the built-in pump assembly 10 and the sample injection assembly work together to dynamically and automatically dilute the sample at a ratio of 1:10 to 1:2, or the operator can dilute it according to a user-defined preset ratio before measurement, ensuring optimal sensitivity and accuracy during the measurement process. Using a power pump and solenoid valve control, the sample aspiration volume and dilution process can be accurately controlled, effectively avoiding measurement errors caused by improper sample processing, and significantly improving its application value and practicality in the clinical field.
[0020] To further improve the accuracy of the measurement results, reference Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the sample introduction assembly includes a sample introduction plate 4 disposed on the sample introduction area 3. The sample introduction plate 4 has a placement slot 5 for inserting the sample to be tested on its surface. A drive motor for rotating the sample introduction plate 4 is disposed at the bottom of the sample introduction plate 4. A sample introduction arm 6 is disposed inside the housing 1, and a first motor and a second motor for controlling the horizontal and vertical movement of the sample introduction arm 6 are also disposed inside the housing 1. A sample introduction needle 7 is disposed on the sample introduction arm 6, and a tubing is disposed inside the sample introduction needle 7. The other end of the tubing is connected to a power pump, which is disposed inside the housing 1, and the other end of the power pump is connected to a bubble detector 8 via a tubing. The upper part of the housing 1 is the control area 2, used to operate the analyzer and clearly display the analysis results; the lower right side of the housing 1 is the reagent placement area, used to store various reagents required for analysis, while the left side is the sample to be tested and the sample introduction area 3. This area is divided into two parts: one is the sample introduction arm 6, which includes vertical and horizontal movement, and the other is the sample introduction plate 4 for the sample to be tested. The sample to be tested is placed on the sample tray 4. After performing the corresponding program operation through the touch screen of the control area 2, the sample tray 4 rotates, rotating the sample to the designated position. When the sample reaches the designated position, the sample injection arm 6 moves forward, driving the injection needle 7 to the top of the sample tube. Then, the sample injection arm 6 moves downward, driving the injection needle 7 downward a corresponding distance. The pump then rotates to draw the sample through the tubing connected to the injection needle 7. After the sample is drawn, it first rises to a fixed position and then moves backward into the instrument to complete the sample extraction. Next, the power pump rotates and pumps the drawn sample through the bubble detector 8 to the electrode assembly 9 for analysis, ensuring accurate and efficient aspiration of the urine sample. The casing 1 also contains the electrode assembly 9, which is connected to the injection needle 7 through tubing. The electrode assembly uses imported materials to manufacture a leadless, combined ion-selective electrode, which is specifically optimized for common electrolyte ions in urine samples. The electrode is filled with an excess of silver chloride, effectively avoiding early failure. Meanwhile, all electrodes employ a unique fully sealed technology, which not only improves electrode stability but also extends their service life. Furthermore, a bubble detection sensor is installed in the tubing between the electrode assembly 9 and the injection needle 7, enabling real-time monitoring of bubble conditions in the tubing and effectively avoiding measurement errors caused by bubble interference, further improving the accuracy of the measurement results. A pump assembly 10 is installed inside the housing 1, which is used to transport waste liquid generated during the measurement process to the waste liquid bottle 11 through tubing, ensuring a clean and hygienic analytical environment. A solenoid valve assembly 12 is installed inside the housing 1, arranged sequentially along the reagent flow direction, for precisely controlling the introduction of different reagents and the discharge of waste liquid, achieving automation and intelligence in the analytical process.The electrode assembly 9, pump assembly 10, and solenoid valve assembly 12 are connected by precision pipelines and together with the sample injection assembly, form a closed flow path system. This flow path system uses the electrode assembly 9 to accurately measure electrolyte ions in the urine sample, ensuring the accuracy of the analysis results.
[0021] Furthermore, the back of the casing 1 features a removable rear cover 13 for convenient daily maintenance and functional expansion. The rear cover 13 integrates a power switch 15, a power socket 14, reagent connectors, and USB and RS232 interfaces, meeting diverse usage needs. In the control area 2, a touchscreen clearly displays parameters and analysis results for the samples to be tested (including urine samples), allowing users to intuitively understand the results. Simultaneously, the analyzer is equipped with a printer 16, which can print out the analysis results instantly for easy recording and archiving.
[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
