Samples can be whole blood, serum, plasma, urine, dialysate and hydration fluid. Electrolyte analyzers are indispensable in clinical testing, where they mainly test and maintain human blood. The balance of osmotic pressure in body fluids is very important for patients who need a large amount of balanced fluid replacement during surgery, burns, diarrhea, acute myocardial infarction, etc. The instrument has high precision and accuracy, and the results measured for any sample are accurate, reliable, fast, and very simple to operate. Therefore, ion detection is an essential general equipment for hospitals at all levels.

A base 6 is installed on the rotating mechanism 2. A lifting mechanism 3 is provided above the base 6. A frame 7 is connected to the lifting mechanism 3. A fixing ring 4 is connected inside the frame 7. The fixing ring 4 is symmetrically provided with clamping seats 5 inside. A first connecting ear 8 and a second connecting ear 9 are respectively provided on both sides of the clamping seat 5. A clamping drive mechanism is provided inside the frame 7, and the clamping drive mechanism includes a two-way adjustment screw 10, a hand wheel 11 and a guide rod 12. A two-way adjustment screw 10 is rotatably provided on one side of the frame 7, and a hand wheel 11 is provided at one end of the two-way adjustment screw 10. A guide rod 12 is provided on the other side of the frame 7. The first connecting ear 8 is threadedly connected to the two-way adjustment screw 10, and the second connecting ear 9 is slidably connected to the guide rod 12. A support plate 13 is provided at the lower inner side of the clamping seat 5.

[0019] When the sample fixing device of the electrolyte analyzer of the utility model fixes the sample test tube, the rotating mechanism 2 is first used to drive the lifting mechanism 3 to rotate the angle so that the frame 7 is rotated to the side away from the automatic sampler of the electrolyte analyzer, and then the sample test tube is placed between the two clamping seats 5, and then the clamping drive mechanism is used to drive the two clamping seats 5 to be relatively close to each other to clamp the sample test tube. When the automatic sampler of the electrolyte analyzer starts to sample, the lifting mechanism 3 is used to drive the frame 7 to rise, so that the automatic sampler pipette of the electrolyte analyzer is extended into the sample test tube for sampling.

[0020] A fixing plate is provided at one end of the assembly connection plate 1 , and a fixing bolt 14 is provided on the fixing plate. The assembly connection plate 1 is detachably mounted to the electrolyte analyzer body via the fixing bolt 14 .

[0021] The rotating mechanism 2 includes a rotating shaft 201 and a rotating drive motor 202. The rotating shaft 201 is rotatably arranged above the assembly connecting plate 1. The base 6 is mounted on the upper end of the rotating shaft 201. A rotating drive motor 202 is mounted above the assembly connecting plate 1 on one side of the rotating shaft 201. Synchronous wheels are arranged on the output end of the rotating drive motor 202 and the rotating shaft 201. The two synchronous wheels are connected by a synchronous belt. The rotating shaft 201 can be driven to rotate by an angle by starting the rotating drive motor 202. In the present utility model, the rotating drive motor 202 is a reduction motor.

[0022] The lifting mechanism 3 includes a support frame 301, a one-way linear screw 302, a positioning rod 303 and a servo motor 304. The support frame 301 is arranged above the base 6. The one-way linear screw 302 is rotatably arranged inside the support frame 301. The one-way linear screw 302 is driven by the servo motor 304.

By starting the servo motor 304 to drive the one-way linear screw 302 to rotate, the frame 7 is lifted and moved on the one-way linear screw 302 and the positioning rod 303.

[0023] Through grooves 15 are symmetrically provided on both sides of the fixing ring 4 , and one end of each of the first connecting ear 8 and the second connecting ear 9 passes through the through grooves 15 .

[0024] A pointer 16 is provided at one end of the first connection seat 305, and a scale line 17 is provided on the support frame 301, and the pointer 16 points to the scale line 17. The utility model can realize the control of the lifting height of the frame 7 by setting the pointer 16 and the scale line 17 to cooperate with each other by observing the length difference between the two positions indicated by the pointer 16 on the scale line 17, thereby ensuring that the automatic sampler of the electrolyte analyzer can realize single quantitative sampling.

[0025] The utility model sets a clamping drive mechanism in the frame 7, connects the symmetrically arranged clamping seat 5 with the two-way adjustment screw 10 and the guide rod 12 of the clamping drive mechanism, and drives the two-way adjustment screw 10 to rotate to synchronously drive the two clamping seats 5 to move relative to each other to clamp the sample tube. The clamping process is simple to operate and has high clamping stability. At the same time, the utility model sets the lifting mechanism 3 on the rotating mechanism 2, and connects the frame 7 with the lifting mechanism 3. The lifting mechanism 3 can start the frame 7 to lift and lower, so that the sample tube clamped by the clamping seat 5 can be close to the automatic sampler of the electrolyte analyzer for sampling. The setting of the rotating mechanism 2 can drive the frame 7 connected to the lifting mechanism 3 to change position, and the clamping seat 5 is rotated to one side to facilitate the rapid fixation of the sample tube, and the position of the automatic sampler of the electrolyte analyzer will not interfere during the process.
