[0002] In the application of biochemical analyzers, probe cleaning is a key step to ensure analysis accuracy and avoid cross contamination.

[0003] At present, biochemical analyzers on the market usually use fixed-position cleaning containers to clean the probe by immersing it in cleaning liquid. This design has several obvious disadvantages: first, the fixed-position cleaning method cannot ensure that every part of the probe can be cleaned evenly and effectively;

[0004] Secondly, the residual liquid after cleaning is likely to form drops on the probe surface, affecting the accuracy of the next use; finally, the cleaning efficiency of this design is low and time-consuming. Summary of the invention

[0009] In the improved cleaning tank for the probe of the biochemical analyzer, the drainage hole is located at the center of the shell, and the bottom of the shell is also provided with a water inlet hole communicating with the inner cavity of the shell.

[0010] In the improved cleaning tank of the probe of the above-mentioned biochemical analyzer, there are two water inlet holes: water inlet hole 1 and water inlet hole 2. The above-mentioned water inlet hole 1 is used to introduce clean water into the shell, and the above-mentioned water inlet hole 2 is used to introduce liquid washing medium into the shell. The above-mentioned water inlet hole 1 and water inlet hole 2 are symmetrically distributed on both sides of the drainage hole.

[0011] In the improved cleaning tank for the probe of the biochemical analyzer, the bottom of the shell is conical, and the drainage hole is located at the conical bottom of the shell.

[0012] The drainage hole is coincident with the axis line of the drainage tube, the water inlet hole 1 is arranged obliquely, and the angle between the water inlet hole 1 and the drainage hole is 10-30 degrees.

[0013] In the improved cleaning tank for the probe of the biochemical analyzer, the lower end of the shell has a protruding connecting tube, which is sleeved on the drain tube and the two are tightly fitted and connected.

[0014] In the improved cleaning tank for the probe of the biochemical analyzer, the connecting tube and the draining tube are connected by threads.

[0015] In the improved cleaning tank of the probe of the above-mentioned biochemical analyzer, the drainage cylinder includes a tubular tube body 1 and a tubular tube body 2. The inner diameter of the above-mentioned tube body 1 is larger than the inner diameter of the tube body 2 and the tube body 1 is connected to the tube body 2. The above-mentioned tube body 1 is located on the upper part of the tube body 2. The tube body 1 is embedded in the connecting cylinder and the two are tightly connected. The above-mentioned tube body 2 is used to be connected to a flexible connecting tube, and there is a smoothly transition section between the tube body 1 and the tube body 2.

[0016] In the improved cleaning tank of the probe of the above-mentioned biochemical analyzer, the above-mentioned positioning structure is located at the transition section, and the positioning structure includes a positioning disk and a locking nut. The above-mentioned transition section has a recessed connecting seat, the above-mentioned positioning disk is annular and the inner edge of the positioning disk is embedded in the connecting seat, the above-mentioned locking nut is threadedly connected at the transition section and the positioning disk is tightly pressed between the connecting seat and the locking nut, and the positioning disk has a penetrating positioning hole.

[0019] A. Preparation: Put the assembled cleaning tank aside, that is, connect the end cover, shell and drain cylinder together and put them aside;

[0020] B. Insert the probe: insert the probe into the cleaning tank through the jack of the end cover;

[0021] C. Cleaning: Clean water is continuously introduced into the water inlet hole 1 of the shell, and liquid cleaning medium is continuously introduced into the water inlet hole 2 at the same time. Clean water hits the end cover at a relatively fast flow rate, and liquid cleaning medium also hits the end cover at a relatively fast flow rate.

In the above process, the probe is stably cleaned by the cleaning liquid;

[0022] D. Dehydration: Rapid airflow is introduced into the water inlet holes 1 and 2. When the rapid airflow is discharged from the drain tube, the probe is stably dehydrated by the rapid airflow. After the probe is pulled out, a clean probe is obtained.

[0023] Compared with the prior art, the improved cleaning tank of the probe of the biochemical analyzer is easy to clean because the end cover, the shell and the drain cylinder are detachably connected and installed, thereby effectively improving the cleaning stability of the cleaning tank.

[0024] At the same time, the end cover can not only position the probe, but also, water inlet hole 1 and water inlet hole 2 are directly opposite to the end cover. After the end cover blocks the clean water and liquid washing medium, the clean water and the washing medium can be stably mixed into a cleaning liquid, and the cleaning liquid flows faster in the shell, and finally the probe can be stably cleaned by the cleaning liquid, and the cleaning effect is relatively high.

[0025] At the same time, the end cover, shell and drain tube are easy to load and unload, and the structure is compact after installation, which has high practical value. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0031] like Figure 1 As shown, the improved cleaning tank of the probe of the biochemical analyzer comprises a cylindrical shell 2, wherein the interior of the shell 2 is a cavity and the upper end is open.

[0032] It also includes an end cover 1 and a cylindrical drainage tube 3, wherein the end cover 1 is detachably connected to the upper port of the shell 2, and the end cover 1 has a socket 1a for inserting a probe therein, the upper end of the drainage tube 3 is connected to the lower end of the shell 2, and the bottom of the shell 2 has a drainage hole 2a that is opposite to the socket 1a, and the drainage hole 2a connects the shell with the drainage tube 3, and the outer side of the drainage tube 3 has a positioning structure that can fix it on the corresponding bracket.

[0033] The drainage hole 2a is located at the center of the shell 2, and the bottom of the shell 2 is also provided with a water inlet hole communicating with the inner cavity of the shell 2.

[0034] The end cover 1 is connected to the upper end of the shell 2 , and the drain cylinder 3 is connected to the lower end of the shell 2 .

[0035] It can be seen that the above structure enables the end cover 1, the shell 2 and the drain tube 3 to be easily assembled and disassembled. After disassembly, the individual parts can be stably cleaned one by one, and after assembly, a compact cleaning tank is formed.

[0036] The cleaning liquid inputted from the water inlet acts on the end cover, which enables the cleaning liquid to flow rapidly in the shell. Since the probe is located in the shell, the probe can be cleaned stably in the end.

[0037] There are two water inlet holes: water inlet hole 1 2b and water inlet hole 2c. The water inlet hole 1 2b is used to introduce clean water into the shell 2, and the water inlet hole 2c is used to introduce liquid washing medium into the shell 2. The water inlet hole 1 2b and the water inlet hole 2c are symmetrically distributed on both sides of the drainage hole 2a.

[0038] The arrangement of the water inlet hole 1 2 b and the water inlet hole 2 c enables the clean water and the detergent to be stably mixed in the housing 2 to form a cleaning liquid.

[0039] Of course, this reduces the number of cleaning fluid mixing devices required.

[0040] The bottom of the shell 2 is conical, and the drainage hole 2 a is located at the conical bottom of the shell 2 .

[0041] Such a structure enables the cleaning liquid to be discharged stably from the drain hole 2a.

[0042] The drainage hole 2a is coincident with the axis line of the drainage tube 3, and the water inlet hole 2b is inclined. The angle between the water inlet hole 2b and the drainage hole 2a is 10 degrees. According to actual conditions, the angle of 30 degrees is also feasible.

[0043] The inclined water inlet hole 1 2b and the water inlet hole 2c are symmetrically arranged on both sides of the drainage hole 2a.

[0044] The inclined water inlet hole 1 2b and the water inlet hole 2c can make the cleaning liquid stably reflux in the shell 2, ensuring stable mixing of the cleaning liquid.

[0045] The lower end of the shell 2 has a protruding connecting tube 2d, which is sleeved on the drainage tube 3 and the two are tightly fitted and connected.

[0046] The shell 2 and the drainage cylinder 2d can be stably fixed together through the connecting cylinder 3d.

[0047] The connecting tube 2d is connected to the drainage tube 3 via threads.

[0048] The drainage cylinder 3 includes a tubular body 1 3a and a tube body 2 3b. The inner diameter of the tube body 1 3a is larger than the inner diameter of the tube body 2 3b and the tube body 1 3a is connected to the tube body 2 3b. The tube body 1 3a is located on the upper part of the tube body 2 3b. The tube body 1 3a is embedded in the connecting cylinder 2d and the two are tightly connected. The tube body 2 3b is used to be connected to a flexible connecting pipe, and a smoothly transition section 3c is provided between the tube body 1 3a and the tube body 2 3b.

[0049] The inner diameter of the pipe body 3b is relatively large, which can avoid the accumulation of cleaning liquid and ensure that the cleaning liquid can be discharged smoothly.

[0050] The setting of the transition section 3c can ensure that the pipe body 1 3a and the pipe body 2 3b with different inner diameters are stably connected.

[0051] The positioning structure is located at the transition section 3c, and the positioning structure includes a positioning disk 4 and a locking nut 5. The transition section 3c is provided with a recessed connecting seat 3c1. The positioning disk 4 is annular and the inner edge of the positioning disk 4 is embedded in the connecting seat 3c1. The locking nut 5 is threadedly connected at the transition section 3c and the positioning disk 4 is tightly pressed between the connecting seat 3c1 and the locking nut 5. The positioning disk 4 has a penetrating positioning hole 4a.

[0052] The positioning plate 4 is positioned between the locking nut 5 and the connecting seat 3c1. Such a structure can eventually stably fix the positioning plate 4 on the drain cylinder 3.

[0053] Of course, such a structure can also make the positioning plate 4 replaceable, thereby ensuring that the positioning structure can be connected in different working occasions.

[0054] The cleaning method of the probe of the biochemical analyzer comprises the following steps:

[0055] A. Preparation: Put the assembled cleaning tank aside, that is, connect the end cover, shell and drain cylinder together and put them aside;

[0056] B. Insert the probe: insert the probe into the cleaning tank through the jack of the end cover;

[0057] C. Cleaning: Clean water is continuously introduced into the water inlet hole 1 of the shell, and liquid cleaning medium is continuously introduced into the water inlet hole 2 at the same time. Clean water hits the end cover at a relatively fast flow rate, and liquid cleaning medium also hits the end cover at a relatively fast flow rate. The liquid cleaning medium and clean water are fully mixed in the shell to form a cleaning liquid. The fast-flowing cleaning liquid is discharged from the drain hole into the drain cylinder, and finally discharged from the drain cylinder. In the above process, the probe is stably cleaned by the cleaning liquid;

[0058] D. Dehydration: Rapid airflow is introduced into the water inlet holes 1 and 2. When the rapid airflow is discharged from the drain tube, the probe is stably dehydrated by the rapid airflow. After the probe is pulled out, a clean probe is obtained.

[0059] The improved cleaning tank of the probe of the biochemical analyzer is easy to clean because the end cover, the shell and the drain cylinder are detachably connected and installed, thereby effectively improving the cleaning stability of the cleaning tank.

[0060] At the same time, the end cover can not only position the probe, but also, water inlet hole 1 and water inlet hole 2 are directly opposite to the end cover. After the end cover blocks the clean water and liquid washing medium, the clean water and the washing medium can be stably mixed into a cleaning liquid, and the cleaning liquid flows faster in the shell, and finally the probe can be stably cleaned by the cleaning liquid, and the cleaning effect is relatively high.

[0061] At the same time, the end cover, shell and drain tube are easy to load and unload, and the structure is compact after installation, which has high practical value.

[0062] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention.
