Description

Technical Field

[0001] The utility model relates to the technical field of full-automatic biochemical analyzers, in particular to a liquid path system of a full-automatic biochemical analyzer. Background Art

[0002] A fully automatic biochemical analyzer is an instrument that measures a specific chemical component in body fluids based on the principle of photoelectric colorimetry. During the operation of a fully automatic biochemical analyzer, since the temperature has a great influence on the reaction results during biochemical reactions, the sensitivity and accuracy of the constant temperature system directly affect the measurement results. Therefore, a constant temperature bath is designed around the colorimetric cup, and a stable constant temperature liquid that is odorless, pollution-free, non-evaporating, and non-deteriorating is added to the constant temperature bath. The constant temperature liquid has a large capacity, good thermal stability, and is uniform. In order to ensure stable and bubble-free circulation of the liquid in the constant temperature bath, the existing system has added a set of bubble removal mechanisms. However, due to the high cost, it is not suitable for some customers. In order to reduce costs, reduce system control pressure, and reduce instrument failure rate, the utility model provides a liquid path system that does not require a bubble removal mechanism, thereby reducing the generation of bubbles when the liquid circulates in the constant temperature bath. Utility Model Content

[0003] In order to overcome the above-mentioned defects in the prior art, the utility model provides a liquid path system of a fully automatic biochemical analyzer.

[0004] A liquid circuit system of a fully automatic biochemical analyzer includes a water inlet pipe, the water inlet pipe is connected to one end of a six-way water inlet and discharge assembly, the second end of the six-way water inlet and discharge assembly is connected to a circulation pump via a horizontal pipe and a transfer pipe, the circulation pump is connected to a constant temperature heating assembly via a connecting pipe, the constant temperature heating assembly is connected to a water inlet of a constant temperature bath via a heating pipe, the water outlet of the constant temperature bath is connected to a three-way end of the six-way water inlet and discharge assembly via a water outlet pipe, the four-way end of the six-way water inlet and discharge assembly is connected to a drainage pipe, the drainage pipe is provided with a solenoid valve, the drainage pipe is located above the six-way water inlet and discharge assembly, and the horizontal pipe and the six-way water inlet and discharge assembly are on the same horizontal line.

[0005] Furthermore, the five-way connection of the six-way water inlet and discharge assembly is connected to a drainage pipe, and a plug is provided at the end of the drainage pipe.

[0006] Furthermore, the six ports of the six-port water inlet and outlet assembly are connected to the circulation pipeline.

[0007] Furthermore, the six-way water inlet and outlet assembly is made of polyethylene.

[0008] Furthermore, the water inlet pipe, horizontal pipe, transfer pipe, connecting pipe, water inlet pipe, water outlet pipe, and drainage pipe are all silicone tubes.

[0009] Due to the adoption of the above technical scheme, the beneficial technical effect of the utility model is: in the utility model, when bubbles are generated in the process of circulation of the liquid, the liquid passes through the six-way water inlet and discharge assembly, and the bubbles will move along the upper part of the six-way water inlet and discharge assembly into the drainage pipe due to their own physical properties, and then be discharged through the drainage pipe. Since the bubbles will move upward into the drainage pipe, they will not enter the horizontal pipe, and thus will not affect the water circulation of the constant temperature bath. The liquid circuit system has a simple structure and effectively reduces the production cost of the enterprise. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0012] In order to more clearly illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of the present invention. For ordinary technicians in this field, without paying any creative work, other embodiments can be obtained based on these drawings and embodiments, which all fall within the scope of protection of the present invention.

[0013] according to Figure 1 As shown, a liquid path system of a fully automatic biochemical analyzer includes a water inlet pipe 1, which is connected to one of the six-way water inlet and discharge assembly 2, and the two-way water inlet and discharge assembly 2 is connected to the circulation pump 5 through a horizontal pipe 3 and a transfer pipe 4. The circulation pump 5 is connected to the constant temperature heating assembly 7 through a connecting pipe 6, and the constant temperature heating assembly 7 is connected to the water inlet of the thermostatic bath through a heating pipe 8. The water outlet of the thermostatic bath is connected to the three-way water inlet and discharge assembly 2 through a water outlet pipe 9, and the four-way water inlet and discharge assembly 2 is connected to a drainage pipe 10. A solenoid valve 11 is provided on the drainage pipe 10. The drainage pipe 10 is located above the six-way water inlet and discharge assembly 2, and the horizontal pipe 3 and the six-way water inlet and discharge assembly 2 are on the same horizontal line.

[0014] In the above-mentioned specific technical scheme, the liquid stored in the fully automatic biochemical analyzer enters the six-way water inlet and discharge assembly 2 through the clean water pipe. At this time, the circulation pump 5 starts to work, and the liquid in the six-way water inlet and discharge assembly 2 enters the circulation pump 5 through the horizontal pipe 3 and the transfer pipe 4, and then enters the constant temperature heating assembly 7 through the connecting pipe 6. The heated liquid enters the constant temperature bath through the heating pipe 8, and the liquid in the constant temperature bath flows back to the six-way water inlet and discharge assembly 2 through the outlet pipe 9. The above actions are repeated, so that the liquid circulates in the constant temperature bath and the six-way water inlet and discharge assembly 2; when bubbles are generated in the liquid during the circulation process, the liquid passes through the six-way water inlet and discharge assembly 2, and the bubbles will move along the top of the six-way water inlet and discharge assembly 2 into the drainage pipe 10 due to their own physical properties, and then be discharged through the drainage pipe 10. Because the bubbles will move upward into the drainage pipe 10, they will not enter the horizontal pipe 3, and thus will not affect the water circulation of the constant temperature bath. The liquid path system has a simple structure and effectively reduces the production cost of the enterprise.

[0015] The five-way connection of the six-way water inlet and discharge assembly 2 is connected to the drain pipe 12, and a plug 13 is provided at the end of the drain pipe 12. When it is necessary to manually drain the liquid in the constant temperature bath, the plug 13 can be pulled out to allow the liquid to be discharged along the drain pipe 12 under the action of gravity.

[0016] The six ports of the water inlet and outlet six-port assembly 2 are connected to the circulation pipe 14 . When the liquid in the thermostatic bath needs to be discharged, the solenoid valve 11 is opened and the liquid flows out through the drainage pipe 10 .

[0017] The six-way water inlet and outlet assembly 2 is made of polyethylene, which has the advantages of being corrosion-resistant and having a long service life.

[0018] The water inlet pipe 1, the horizontal pipe 3, the transfer pipe 4, the connecting pipe 6, the water inlet pipe 1, the water outlet pipe 9, and the drainage pipe 10 are all silicone tubes.

[0019] The above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the present invention. The scope of protection of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and scope of protection of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the scope of protection of the present invention.
