TECHNICAL FIELD

[0002] The electrolyte analyzer is indispensable in clinical examination. In the clinic, it mainly tests the balance of osmotic pressure in the human blood and body fluid. The ion test and detection are very important for patients who need a large amount of balanced fluid, such as surgery, burns, diarrhea, acute myocardial infarction, etc. The instrument has high precision and accuracy, and the results measured by the instrument for any sample are accurate, reliable, fast and very simple to operate. Ion detection is a necessary general equipment for hospitals at all levels. The electrolyte analyzer uses ion selective electrode measurement method to realize accurate detection. The instrument has six electrodes: sodium, potassium, chlorine, ion calcium, lithium and reference electrode. Each electrode has an ion selective membrane, which will react with the corresponding ion in the measured sample. The membrane is an ion exchanger, which reacts with the ion charge and changes the membrane potential, so as to detect the potential between the liquid, sample and membrane.

[0003] The sampling needle aperture of the electrolyte analyzer is usually small, and the types of detection carriers are various, such as blood, serum, urine, etc. If the blood sample is not fully centrifuged, it may contain fibrin clots, blood cells, etc. The serum sample may have protein precipitation, and the urine sample may have crystals or impurities, etc. These substances are easy to block the sampling needle port during sampling, affecting the normal use of the instrument and the accuracy of the detection results.

[0036] Embodiment one:

[0037] Please refer to the drawings of the present application Figure 1 - the drawings of the present application Figure 3The embodiment of the present application provides an electrolyte sample injection assembly and an analysis device thereof, which comprises a detection table 1, an L-shaped support 2 is slidably connected above the detection table 1, an electric push cylinder one 3 is fixedly connected to the top of the support 2, a connecting piece 4 is fixedly connected to the driving end of the electric push cylinder one 3, an analysis assembly 5 is mounted on the surface of the connecting piece 4, the analysis assembly 5 comprises a cylinder body 51, the outer wall of the cylinder body 51 is fixedly connected with the connecting piece 4, a plunger 52 is slidably connected in the cylinder body 51, a four-way joint 53 is fixedly arranged at the bottom end of the cylinder body 51, a needle tube 54 is fixedly arranged at the bottom end of the four-way joint 53, a flow path switching mechanism 56 is mounted in the four-way joint 53, a plurality of limiting protrusions 55 are fixedly connected to the top end of the plunger 52, a plurality of limiting grooves 59 are formed in the upper side wall of the support 2, one end of the limiting protrusion 55 away from the plunger 52 penetrates through the limiting groove 59, a liquid discharge end 57 is fixedly connected to the bottom end of the plunger 52, a discharge check valve is fixedly arranged on the liquid discharge end 57, and an electrode box 58 is connected to the bottom end of the liquid discharge end 57 through a conveying pipe.

[0038] Specifically, the electric push cylinder one 3 is contracted to drive the cylinder body 51 to rise, so that the top end of the plunger 52 abuts against the inner top wall of the support 2, and in the subsequent gradual contraction of the electric push cylinder one 3, the bottom end of the plunger 52 slides to the bottom of the cylinder body 51, thereby increasing the height of the needle tube 54 and making the bottom end of the needle tube 54 higher than the test tube. During detection, the test tube to be detected is conveyed to the lower side of the support 2, then the electric push cylinder one 3 is controlled to extend to drive the cylinder body 51 to descend so that the bottom end of the needle tube 54 is inserted into the test tube, and in the subsequent descending process, the limiting protrusions 55 are limited by the limiting grooves 59, so that the height of the plunger 52 does not change while the cylinder body 51 descends, thereby generating negative pressure in the cylinder body 51. In this process, the flow path switching mechanism 56 is closed to the liquid discharge end 57, so that the detection carrier in the test tube is sucked into the needle tube 54. After the sucking is completed, the electric push cylinder one 3 is contracted to drive the cylinder body 51 to rise, so that the top end of the plunger 52 abuts against the inner top wall of the support 2, and in the subsequent gradual contraction of the electric push cylinder one 3, the bottom end of the plunger 52 slides to the bottom of the cylinder body 51. In this process, the flow path switching mechanism 56 is closed to the needle tube 54, so as to prevent the detection carrier from being squeezed out of the needle tube 54, thereby enabling the detection carrier to be squeezed into the electrode box 58 from the liquid discharge end 57 for detection.

[0056] Please refer to the accompanying drawings Figure 11 In the case that the test tube and the rubber layer 93 have low friction, the bearing seat 913 may not be able to well drive the test tube to rotate when rotating, therefore, another structure is provided in the above embodiment: a plurality of grooves 914 are arranged on the surface of the bearing seat 913, and a clamping plate 915 in inverted L shape is slidably connected in the groove 914, and the side wall of the clamping plate 915 is fixedly connected with an elastic member two 916, and the end of the elastic member two 916 away from the clamping plate 915 is fixedly connected with the inner wall of the groove 914.

[0057] Specifically, the clamping plate 915 slides away from the placing groove by the pulling force of the elastic member two 916, so that the distance between the two clamping plates 915 is greater than the diameter of the test tube, facilitating the insertion of the test tube.

[0058] Please refer to the accompanying drawings Figure 11 The upper surface of the mounting plate 955 is fixedly connected with a supporting member 958, the upper surface of the supporting member 958 is fixedly connected with an annular extrusion ring 959, and the top end of the extrusion ring 959 is arranged with an annular chamfer.

[0059] Specifically, the electric push cylinder two 941 extends to drive the mounting plate 955, the supporting member 958 and the extrusion ring 959 to rise synchronously, and the extrusion ring 959 is inserted into the gap 912, and in the process of rising of the extrusion ring 959, the bottom end of the clamping plate 915 moves laterally along the chamfer and is inserted into the inside of the extrusion ring 959, so that the extrusion ring 959 pushes the clamping plate 915 to slide to one side of the test tube, thereby clamping the test tube by the clamping plate 915, so that the test tube is stably connected with the bearing seat 913, which helps to stably drive the test tube to rotate when the bearing seat 913 rotates to adjust the angle of the identification code.

[0060] Workflow: when detecting, the test tube is inserted into the sample disc 91 through the placement opening and the placement groove in sequence, the sample disc 91 is rotated by the motor 10, so that the test tube moves to the analysis assembly 5 for detection in sequence, and the identification code on the test tube can be scanned by the scanning device 92, then the first electric push cylinder 3 is extended, the cylinder body 51 is lowered to make the bottom end of the needle tube 54 inserted into the test tube, and in the subsequent lowering process, the limiting protrusion 55 is limited by the limiting groove 59, so that the height of the plunger 52 does not change while the cylinder body 51 is lowered, thereby generating negative pressure in the cylinder body 51, and in this process, the flow path switching mechanism 56 closes the liquid discharge end 57, so that the detection carrier in the test tube is sucked into the needle tube 54, after the suction is completed, the first electric push cylinder 3 is retracted to drive the cylinder body 51 to rise, so that the top end of the plunger 52 abuts against the inner top wall of the support 2, and in the subsequent gradual retraction of the first electric push cylinder 3, the bottom end of the plunger 52 slides to the bottom of the cylinder body 51, and in this process, the flow path switching mechanism 56 closes the needle tube 54 to prevent the detection carrier from being squeezed out of the needle tube 54, so that it can be squeezed into the electrode box 58 from the liquid discharge end 57 for detection, and when the needle tube 54 is blocked during the suction process, the first electric push cylinder 3 is retracted to drive the cylinder body 51 to rise, and when the plunger 52 is about to be lowered to the bottom of the cylinder body 51, the flow path switching mechanism 56 closes the liquid discharge end 57 and opens the needle tube 54, so that the fluid in the cylinder body 51 generates a large pressure under the extrusion of the plunger 52, which flushes out the blockage in the needle tube 54, achieving the effect of automatic cleaning of the needle tube 54 without manual cleaning.

[0061] When the test tube is inserted into the placement groove, the rubber layer 93 increases the friction with the test tube, so that when the identification code on the test tube is misaligned with the scanning device 92, the second electric push cylinder 941 is extended to push the elastic telescopic rod 942 to rise, the elastic telescopic rod 942 drives the drive column 943 to rise, the drive column 943 moves into the notch 912 and makes the connecting protrusion 944 abut against the bottom end of the bearing seat 913, and when the second electric push cylinder 941 is extended to push the elastic telescopic rod 942 to rise, the elastic telescopic rod 942 drives the mounting plate 955 to rise, the mounting plate 955 rises to drive the extrusion frame 954 to rise while pushing the toothed plate 953 to move laterally, the toothed plate 953 moves to drive the gear 952 to rotate, and the gear 952 rotates to drive the drive column 943 to rotate, so that after the connecting protrusion 944 is inserted into the connecting groove 945, the test tube is rotated to enable the scanning device 92 to scan the identification code on the test tube.

[0062] After the detection is completed, the analysis assembly 5 to be cleaned is moved to above the cleaning chamber 81 by the electric sliding table 6, then the cleaning liquid is drawn into the cleaning chamber 81 by the delivery pump 84, and the cleaning liquid is drawn by the analysis assembly 5 for automatic cleaning, and the cleaning waste liquid in the cleaning chamber 81 and the electrode box 58 can be discharged into the container two 83 for temporary storage by opening the electromagnetic valve, achieving the effect of cleaning the analysis assembly 5.
