Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a rotary feed electrolyte analyzer. Background Technology

[0002] Traditional electrolyte analyzers generally use a single-channel linear injection structure. The linear injection system requires a motor to drive the sample holder to move one by one along the guide rail to the detection position. After completing a single test, the sample holder needs to be reset and moved out of the detection position. This means that the sample tubes after the test need to be unloaded during the movement before the sample tubes can be loaded again, thus extending the testing cycle.

[0003] Secondly, when the sampling needle of a traditional electrolyte analyzer is pulled out of the sample tube, the liquid inside the tube rebounds due to negative pressure, forming tiny aerosols that adhere to the outer wall of the sampling needle. If not cleaned in time, these aerosols may contaminate subsequent samples, especially when testing highly infectious samples (such as hepatitis B virus positive serum). Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the existing technology. This utility model proposes a rotary feed electrolyte analyzer.

[0005] To address the aforementioned issues raised by traditional electrolyte analyzers, which generally employ a single-channel linear injection structure, requiring a motor-driven sample holder to move sequentially along a guide rail to the detection position and then repositioning the sample holder after each test, necessitating the unloading of sample tubes during the process before reloading, thus extending the testing cycle. Secondly, in traditional electrolyte analyzers, when the sample tube is withdrawn, the liquid inside the tube rebounds due to negative pressure, forming tiny aerosols that adhere to the outer wall of the aspiration needle. If not cleaned promptly, these aerosols can contaminate subsequent samples, posing a higher risk, especially when testing highly infectious samples. The technical solution adopted in this invention is: A rotary inlet electrolyte analyzer includes an electrolyte analyzer body, an inlet stage, and a sampling seat; The rotating sampling assembly is used to drive the sampling tube to rotate and inject the sample; The rotation sampling assembly includes: A rotating disk and a sample holder disposed on the upper end of the rotating disk, wherein the rotating disk is rotatably disposed on the upper end of the sample inlet stage and is used to drive the sampling tube to rotate and be positioned. The sample pump and the aspiration needle connected to the lower end of the sample pump are used to draw samples from the inside of the sampling tube. The first transmission mechanism is connected to the sample pump and is used to drive the sample pump and the aspiration needle to move vertically. A cleaning assembly for cleaning the sampling needle; The cleaning assembly includes: The cleaning chamber is used to surround and clean the sampling needle; The second transmission mechanism is connected to the cleaning chamber and is used to drive the cleaning chamber to move horizontally.

[0006] Preferably, a motor is fixedly connected inside the front end of the electrolyte analyzer body, the rotating disk is fixedly connected to the upper end of the motor, and the sample rack is distributed in a ring structure.

[0007] Preferably, a positioning sensor is fixedly supported on the outer side of the upper end of the injection stage, and a positioning plate matching the positioning sensor is installed on the upper end of the rotating disk.

[0008] Preferably, the first transmission mechanism includes a first electric telescopic rod and a connecting plate fixedly installed on the upper end of the sampling seat, the lower telescopic part of the first electric telescopic rod is fixedly connected to the first connecting plate, and the sample pump is fixedly connected to the lower part of the first connecting plate.

[0009] Preferably, the sample pump has a fixedly connected sample outlet at its outer end, which is connected to the main body of the electrolyte analyzer via a connecting hose. The upper sides of the first connecting plate are fixedly installed with first sliding rods, which are movably connected to the upper end of the sampling seat.

[0010] Preferably, the second transmission mechanism includes a second electric telescopic rod and a second connecting plate fixedly installed on the side of the sampling seat. The telescopic portion of the outer end of the second electric telescopic rod is fixedly connected to the second connecting plate, and the second connecting plate is distributed in a T-shape.

[0011] Preferably, the cleaning chamber is fixedly installed through the outer end of the second connecting plate. A cleaning port is provided at the upper end of the cleaning chamber. A cleaning fluid inlet is fixedly connected to the outer side of the upper end of the cleaning chamber. The cleaning fluid inlet is connected to an external cleaning fluid supply pipeline through a connecting hose. A waste liquid port is provided at the outer side of the lower end of the cleaning chamber. The waste liquid port is connected to an external waste liquid collection pipeline.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention enables the sample holder and its upper-positioned sample tube to rotate cyclically. During rotation, the precise rotation and positioning of the rotating disk are achieved through the coordinated action of the positioning plate and the positioning sensor. When the sample tube rotates to the designated position, the first electric telescopic rod extends downward, driving the sample pump and the aspiration needle to move linearly downward through the first connecting plate, allowing the aspiration needle to be inserted into the sample tube for sampling. After sampling, the first electric telescopic rod retracts and resets the sample pump and aspiration needle, while the sample tube continues to rotate cyclically, thus facilitating synchronous loading and unloading of the sample tube during the cyclic rotation process. This invention also allows for the extension of the second electric telescopic rod after the sampling needle retracts and resets, which, via the second connecting plate, moves the cleaning chamber outward to a suitable position. Subsequently, the second electric telescopic rod is controlled again to move the sampling needle downward in a straight line into the cleaning chamber. At this point, the external cleaning fluid supply pipe is opened, allowing the cleaning fluid to be discharged into the cleaning chamber to rinse the sampling needle, effectively removing residual liquid adhering to the outer wall of the needle. After rinsing, the waste liquid is discharged through the waste liquid outlet to the external waste liquid collection pipe. Through this series of operations, the rotating sample introduction function is achieved while facilitating the cleaning of the sampling needle, improving the efficiency and accuracy of electrolyte analysis.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0016] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0017] Please see Figure 1- Figure 4 This embodiment proposes a rotary feed electrolyte analyzer, including an electrolyte analyzer body 1, a sample inlet stage 2, and a sample holder 3, wherein the sample inlet stage 2 and the sample holder 3 are fixedly installed on the upper end of the electrolyte analyzer body 1.

[0018] Inside the front end of the electrolyte analyzer body 1, a motor 4 is fixedly installed. A rotating disk 5 is fixedly mounted on the upper drive shaft of the motor 4, and the rotating disk 5 is horizontally connected to the upper end of the sample stage 2 via a rotating shaft. This design allows the motor 4 to precisely drive the rotating disk 5 to rotate. A sample holder 6 is fixedly mounted on the upper end of the rotating disk 5. This sample holder 6 has a ring-shaped structure and is used for precise positioning of the sample tubes. Furthermore, a positioning sensor 7 is fixedly mounted on the outer upper end of the sample stage 2, and a positioning plate 8 matching the positioning sensor 7 is correspondingly mounted on the upper end of the rotating disk 5. Through the coordinated work of the positioning plate 8 and the positioning sensor 7, precise rotational positioning of the rotating disk 5 can be achieved.

[0019] The upper end of the sampling base 3 is fixedly mounted with a first electric telescopic rod 9, the lower telescopic part of which is connected to the first connecting plate 10. The lower end of the first connecting plate 10 is fixedly mounted with a sample pump 11, and the lower end of the sample pump 11 is fixedly connected to a sampling needle 12 for aspirating the sample from inside the sample tube. The sampling needle 12 and the sample tube positioned at the upper end of the sample holder 6 are kept on the same vertical line to ensure the accuracy of sampling. The outer end of the sample pump 11 is also fixedly connected to a sample outlet 13, which is connected to the electrolyte analyzer body 1 (not shown in the figure) through a connecting hose, so that the sample aspirated by the sample pump 11 can be discharged into the electrolyte analyzer body 1 for detection. To ensure the vertical linear movement stability of the first connecting plate 10, the first sliding rods 14 are fixedly mounted on both sides of the upper end of the first connecting plate 10, and the first sliding rods 14 are movably connected to the upper end of the sampling base 3.

[0020] In addition, this embodiment is equipped with a second electric telescopic rod 15, which is fixedly installed on the side of the sampling seat 3. The telescopic part of the outer end of the second electric telescopic rod 15 is connected to the second connecting plate 16, and the second connecting plate 16 is T-shaped. The outer end of the second connecting plate 16 is fixedly installed through the cleaning chamber 17. The upper end of the cleaning chamber 17 has a cleaning port 18 for the sampling needle 12 to extend into the cleaning chamber 17 for cleaning. The upper outer side of the cleaning chamber 17 is also fixedly connected to the cleaning liquid inlet 19, which is connected to the external cleaning liquid supply pipeline (not shown in the figure) through a connecting hose, so as to discharge the cleaning liquid into the cleaning chamber 17. The lower outer side of the cleaning chamber 17 has a waste liquid port 20, which is connected to the external waste liquid collection pipeline (not shown in the figure), for discharging the waste liquid inside the cleaning chamber 17 to the outside.

[0021] Please continue reading. Figure 1 - Figure 4 In this embodiment, during use, the motor 4 is first activated, driving the rotating disk 5 to rotate, which in turn causes the sample holder 6 and the sample tube positioned at its upper end to rotate and shift cyclically. During rotation, the positioning plate 8 and the positioning sensor 7 work together to achieve precise rotational positioning of the rotating disk 5. When the sample tube rotates to the designated position, the first electric telescopic rod 9 is activated to extend downwards, driving the sample pump 11 and the aspiration needle 12 to move downwards linearly via the first connecting plate 10, allowing the aspiration needle 12 to be inserted into the sample tube for sampling. After sampling is completed, the first electric telescopic rod 9 causes the sample pump 11 and the aspiration needle 12 to retract and reset, while the sample tube continues to rotate and shift cyclically, thus facilitating synchronous loading and unloading of the sample tube during the cyclic rotation process.

[0022] Simultaneously, after the sampling needle 12 retracts and resets, we control the second electric telescopic rod 15 to extend, which, via the second connecting plate 16, moves the cleaning chamber 17 outward to a suitable position. Then, we control the second electric telescopic rod 15 again to move the sampling needle 12 downward in a straight line into the cleaning chamber 17. At this point, the external cleaning fluid supply pipe is opened, and the cleaning fluid is discharged into the cleaning chamber 17 to rinse the sampling needle 12, effectively removing residual liquid adhering to the outer wall of the sampling needle 12. After rinsing, the waste liquid is discharged through the waste liquid port 20 to the external waste liquid collection pipe. Through this series of operations, the rotary sample introduction function is realized, improving the efficiency and accuracy of electrolyte analysis.

[0023] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
