Description

Technical Field

[0001] The invention relates to the technical field of biomedicine, and in particular to a needle cleaning system of an analyzer. Background Art

[0002] In modern biological sample analysis, the sampling needle is an important component used to absorb test samples or chemical reagents. In order to ensure the accuracy and reliability of the test results, the sampling needle must be thoroughly cleaned after each use to reduce cross-contamination between samples. Therefore, the development of an efficient sampling needle cleaning system has become an important research direction in this field. At present, the sampling needle cleaning technology on the market mainly adopts a combination of inner and outer wall cleaning. The inner wall cleaning is usually pushed by a pump or syringe to flush the inner wall with high-pressure water to ensure the removal of residues.

[0003] However, in the needle cleaning system of the high-speed analyzer, due to the need to clean multiple sampling needles, the existing cleaning solutions often require multiple pumps and complex piping systems, resulting in increased system costs and increased maintenance difficulty.

[0004] BACKGROUND OF THE INVENTION The above information disclosed is only for understanding the background of the inventive concept and may contain information that does not constitute the prior art. Summary of the invention

[0005] Based on this, it is necessary to provide a needle cleaning system for an analyzer to address the above problems.

[0006] The present application provides a needle cleaning system for an analyzer, comprising:

[0007] A liquid supply component, the liquid supply component is used to supply cleaning liquid;

[0008] A booster pump, the booster pump being in communication with the liquid supply assembly;

[0009] A multi-way valve, wherein the multi-way valve has a liquid inlet end and a plurality of liquid outlet ends, the liquid inlet end is connected to the liquid supply assembly through the booster pump, and the booster pump can pressurize the cleaning liquid and deliver it to the multi-way valve; and

[0010] A plurality of shunt assemblies, each of which comprises a needle and a shunt block, each of which has an inlet and a shunt port, the inlet being able to communicate with the liquid outlet and corresponding one to one, and the needle being communicated with the shunt port;

[0011] When the inner wall of the needle of a diverter assembly is to be cleaned, one of the liquid outlet ends of the multi-way valve is opened and connected to the inlet of the diverter block corresponding to the diverter assembly, and the other liquid outlet ends of the multi-way valve are closed.

[0012] The needle cleaning system of the above analyzer can at least achieve the following beneficial effects: by pressurizing the cleaning liquid to the multi-way valve through the booster pump, the flow rate and cleaning effect of the cleaning liquid can be effectively improved, thereby ensuring the thorough cleaning of the inner wall of the sampling needle and reducing the risk of cross contamination. The design of the multi-way valve allows the shunt component to be flexibly selected as needed, avoiding unnecessary cleaning operations and improving the flexibility and controllability of the system. By controlling the switch of the multi-way valve, the cleaning action of different shunt components can be accurately controlled to ensure the synchronization and effectiveness of the cleaning process and avoid flow fluctuations during the cleaning process. Through the design of the multi-way valve, multiple liquid outlets are connected to the shunt component, avoiding the use of multiple pumps, simplifying the system structure, and reducing the complexity of the equipment. Due to the design of a single booster pump and a multi-way valve, the number of required equipment is reduced, thereby reducing material costs and production costs and improving economy. The streamlined system structure and reduced number of components also make the maintenance of the equipment easier, reduce the failure rate, and improve the reliability of the equipment.

[0013] In some embodiments, the number of needles corresponds to the number of shunt ports. By pairing each needle with a corresponding shunt port, it can be ensured that the cleaning solution can be accurately delivered to each needle, avoiding confusion or misoperation that may occur during the cleaning process, and improving the pertinence and effectiveness of the cleaning. The one-to-one design makes the cleaning process more efficient. When a specific needle needs to be cleaned, the system can quickly switch to the corresponding shunt port, reducing the cleaning time and improving the working efficiency of the analyzer.

[0014] In some embodiments, the needle includes a reagent needle and a sample needle.

[0015] In some embodiments, the reagent needle includes a first reagent needle and a second reagent needle, the diversion port includes a first diversion port, a second diversion port and a third diversion port, the first reagent needle is connected to the first diversion port, the second reagent needle is connected to the second diversion port, and the sample needle is connected to the third diversion port; wherein, when the inner walls of the first reagent needle, the second reagent needle and the sample needle of a diversion component are to be cleaned, one of the liquid outlet ends of the multi-way valve is opened and connected to the inlet of the diversion block corresponding to the diversion component, and the other liquid outlet ends of the multi-way valve are closed.

[0016] In some embodiments, each of the shunt components further includes a first valve body, a second valve body and a third valve body, the first shunt port can be communicated with the first reagent needle through the first valve body, the second shunt port can be communicated with the second reagent needle through the second valve body, and the third shunt port can be communicated with the sample needle through the third valve body; when the inner wall of the first reagent needle, the second reagent needle and the sample needle of a shunt component is to be cleaned, in the shunt component to be cleaned, the first valve body, the second valve body and the third valve body are first closed until the outlet pressure of the booster pump meets the predetermined threshold and then opened. During the cleaning process, one of the liquid outlet ends of the multi-way valve is opened and connected to the inlet of the shunt block corresponding to the shunt component. This design ensures that the cleaning fluid can effectively flow into the required inner wall of the needle to achieve the purpose of cleaning. During the cleaning process, the remaining liquid outlet ends remain closed. This measure can prevent the cleaning fluid from flowing to the needle that does not need to be cleaned, avoiding the waste of cleaning fluid and the risk of cross contamination. Since the cleaning fluid only flows to the needles that need to be cleaned, the cleaning time is reduced, the overall cleaning efficiency is improved, and the equipment can be quickly restored to normal working state. Before cleaning, the first valve body, the second valve body and the third valve body in the diversion assembly are all closed first. This operation can effectively prevent the cleaning fluid from flowing into the needle before reaching the appropriate pressure, thereby avoiding potential uneven cleaning or liquid overflow. Start the booster pump to gradually increase the outlet pressure. At this time, the outlet pressure of the booster pump will continue to increase until it reaches a predetermined threshold. After the outlet pressure of the booster pump meets the predetermined threshold, the first valve body, the second valve body and the third valve body are opened in sequence. The choice of this timing is crucial. When the pressure reaches the predetermined threshold, the cleaning fluid can enter the inner wall of each needle at a sufficient flow rate and pressure to effectively clean it. After the outlet pressure of the booster pump reaches the predetermined threshold, it can ensure that the cleaning fluid enters the inner wall of the needle at an appropriate pressure and flow rate, thereby effectively flushing away the attached residues and impurities and improving the cleaning effect.

[0017] In some embodiments, each of the diverter components further includes a boost reflux valve, and each of the diverter blocks has a reflux port, which can be connected to the liquid supply component through the boost reflux valve; when the inner wall of the first reagent needle, the second reagent needle and the sample needle of a diverter component is to be cleaned, in the diverter component to be cleaned, the first valve body, the second valve body and the third valve body are first closed, and the boost reflux valve is opened. After the outlet pressure of the boost pump meets the predetermined threshold, the first valve body, the second valve body and the third valve body are opened again, and the boost reflux valve is closed. The opening of the boost reflux valve allows the outlet pressure of the boost pump to reach the predetermined threshold faster. Since the outlet pressure of the boost pump can reach the predetermined value faster, the cleaning fluid can enter the inner wall of the needle faster, achieving efficient cleaning, reducing waiting time, and improving work efficiency.

[0018] In some embodiments, the needle cleaning system of the analyzer also includes a booster shunt and a booster reflux valve, wherein the booster shunt has an inlet, a first outlet and a second outlet, wherein the inlet is connected to the booster pump, the first outlet can be connected to the liquid inlet end of the multi-way valve, and the second outlet can be connected to the liquid supply assembly through the booster reflux valve; when the inner wall of the first reagent needle, the second reagent needle and the sample needle of a shunt assembly is to be cleaned, in the shunt assembly to be cleaned, the first valve body, the second valve body and the third valve body are first closed, the booster reflux valve is opened, and after the outlet pressure of the booster pump meets the predetermined threshold, the first valve body, the second valve body and the third valve body are opened again, and the booster reflux valve is closed. Compared with setting a corresponding booster reflux valve in each shunt assembly, this embodiment can use only a single booster reflux valve, and reducing the number of booster reflux valves can simplify the system design and reduce the system complexity. This helps to reduce potential failure points and improve the reliability of the system. Using fewer components reduces production and maintenance costs. The material and installation costs of each booster return valve can be accumulated, which will directly reduce the overall cost. In addition, with fewer components in the system, maintenance and repair work becomes simpler, and operators can identify and deal with problems more quickly.

[0019] In some embodiments, the needle cleaning system of the analyzer further includes a measuring system first reagent syringe, and the first valve body is connected to the first reagent needle through the measuring system first reagent syringe.

[0020] In some embodiments, the needle cleaning system of the analyzer further includes a measuring system second reagent syringe, and the second valve body is connected to the second reagent needle through the measuring system second reagent syringe.

[0021] In some embodiments, the needle cleaning system of the analyzer further includes a measuring system sample syringe, and the third valve body is connected to the sample needle through the measuring system sample syringe.

[0022] In some embodiments, the liquid supply component is a cleaning container, and the cleaning container is used to load the cleaning liquid.

[0023] In some embodiments, the liquid supply assembly includes a pipeline liquid supply end and a pipeline return end, the booster pump is connected to the pipeline liquid supply end, and the booster return valve is connected to the pipeline return end. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0031] See also Figure 1 and Figure 2 In some embodiments, the present invention provides a needle cleaning system for an analyzer, which includes a liquid supply component 10, a booster pump 20, a multi-way valve 30, and a plurality of diversion components. The liquid supply component 10 is used to supply cleaning liquid; the booster pump 20 is connected to the liquid supply component 10; the multi-way valve 30 has a liquid inlet and multiple liquid outlets, the liquid inlet is connected to the liquid supply component 10 through the booster pump 20, and the booster pump 20 can pressurize the cleaning liquid and deliver it to the multi-way valve 30; each of the diverter components includes a needle 40 and a diverter block 50, each of the diverter blocks 50 has an inlet and a diverter port, the inlet can be connected to the liquid outlet and correspond one to one, and the needle 40 is connected to the diverter port; wherein, when the inner wall of the needle 40 of a diverter component is to be cleaned, one of the liquid outlets of the multi-way valve 30 is opened and connected to the inlet of the diverter block 50 corresponding to the diverter component, and the remaining liquid outlets of the multi-way valve 30 are closed.

[0032] The needle cleaning system of the above analyzer can at least achieve the following beneficial effects: by pressurizing the cleaning liquid to the multi-way valve 30 through the booster pump 20, the flow rate and cleaning effect of the cleaning liquid can be effectively improved, thereby ensuring the thorough cleaning of the inner wall of the sampling needle and reducing the risk of cross contamination. The design of the multi-way valve 30 allows the shunt component to be flexibly selected as needed, avoiding unnecessary cleaning operations and improving the flexibility and controllability of the system. By controlling the switch of the multi-way valve 30, the cleaning action of different shunt components can be accurately controlled to ensure the synchronization and effectiveness of the cleaning process and avoid flow fluctuations during the cleaning process. Through the design of the multi-way valve 30, multiple liquid outlets are connected to the shunt component, avoiding the use of multiple pumps, simplifying the system structure, and reducing the complexity of the equipment. Due to the design of a single booster pump 20 and a multi-way valve 30, the number of required equipment is reduced, thereby reducing material costs and production costs and improving economy. The streamlined system structure and reduced number of components also make the maintenance of the equipment easier, reduce the failure rate, and improve the reliability of the equipment.

[0033] like Figure 1 and Figure 2As shown, in some embodiments, the number of needles 40 corresponds to the number of shunt ports. By pairing each needle 40 with a corresponding shunt port, it can be ensured that the cleaning liquid can be accurately delivered to each needle 40, avoiding confusion or misoperation that may occur during the cleaning process, and improving the pertinence and effectiveness of the cleaning. The one-to-one design makes the cleaning process more efficient. When a specific needle 40 needs to be cleaned, the system can quickly switch to the corresponding shunt port, reducing the cleaning time and improving the working efficiency of the analyzer.

[0034] like Figure 1 and Figure 2 As shown, in some embodiments, the needle 40 includes a reagent needle 41 and a sample needle 42 .

[0035] like Figure 1 and Figure 2 As shown, in some embodiments, the reagent needle 41 includes a first reagent needle 411 and a second reagent needle 412, the diversion port includes a first diversion port, a second diversion port and a third diversion port, the first reagent needle 411 is connected to the first diversion port, the second reagent needle 412 is connected to the second diversion port, and the sample needle 42 is connected to the third diversion port; wherein, when the inner walls of the first reagent needle 411, the second reagent needle 412 and the sample needle 42 of a diversion component are to be cleaned, one of the liquid outlet ends of the multi-way valve 30 is opened and connected to the inlet of the diversion block 50 corresponding to the diversion component, and the remaining liquid outlet ends of the multi-way valve 30 are closed.

[0036] like Figure 1 and Figure 2As shown, in some embodiments, each of the diverter components further includes a first valve body 61, a second valve body 62 and a third valve body 63, the first diverter port can be communicated with the first reagent needle 411 through the first valve body 61, the second diverter port can be communicated with the second reagent needle 412 through the second valve body 62, and the third diverter port can be communicated with the sample needle 42 through the third valve body 63; when the inner wall of the first reagent needle 411, the second reagent needle 412 and the sample needle 42 of a diverter component is to be cleaned, in the diverter component to be cleaned, the first valve body 61, the second valve body 62 and the third valve body 63 are all closed first, and then opened after the outlet pressure of the booster pump 20 meets the predetermined threshold. During the cleaning process, one of the liquid outlet ends of the multi-way valve 30 is opened and communicated with the inlet of the diverter block 50 corresponding to the diverter component. This design ensures that the cleaning liquid can effectively flow into the required inner wall of the needle 40 to achieve the purpose of cleaning. During the cleaning process, the remaining liquid outlet ends remain closed. This measure can prevent the cleaning liquid from flowing to the needle 40 that does not need to be cleaned, avoiding the waste of cleaning liquid and the risk of cross contamination. Since the cleaning liquid only flows to the needle 40 that needs to be cleaned, the cleaning time is reduced, the overall cleaning efficiency is improved, and the equipment can be quickly restored to normal working state. Before cleaning, the first valve body 61, the second valve body 62 and the third valve body 63 in the diversion assembly are all closed first. This operation can effectively prevent the cleaning liquid from flowing into the needle 40 before reaching the appropriate pressure, thereby avoiding potential uneven cleaning or liquid overflow. Start the booster pump 20 to gradually increase the outlet pressure. At this time, the outlet pressure of the booster pump 20 will continue to increase until it reaches a predetermined threshold. After the outlet pressure of the booster pump 20 meets the predetermined threshold, open the first valve body 61, the second valve body 62 and the third valve body 63 in sequence. The timing is crucial. When the pressure reaches a predetermined threshold, the cleaning liquid can enter the inner wall of each needle 40 at a sufficient flow rate and pressure to effectively clean it. After the outlet pressure of the booster pump 20 reaches a predetermined threshold, it can ensure that the cleaning liquid enters the inner wall of the needle 40 at an appropriate pressure and flow rate, thereby effectively flushing away attached residues and impurities and improving the cleaning effect.

[0037] like Figure 1As shown, in some embodiments, each of the diverter components also includes a boost reflux valve 70, and each of the diverter blocks 50 has a reflux port, which can be connected to the liquid supply component 10 through the boost reflux valve 70; when the inner walls of the first reagent needle 411, the second reagent needle 412 and the sample needle 42 of a diverter component are to be cleaned, in the diverter component to be cleaned, the first valve body 61, the second valve body 62 and the third valve body 63 are first closed, and the boost reflux valve 70 is opened. After the outlet pressure of the boost pump 20 meets the predetermined threshold, the first valve body 61, the second valve body 62 and the third valve body 63 are opened again, and the boost reflux valve 70 is closed. The opening of the boost reflux valve 70 enables the outlet pressure of the boost pump 20 to reach the predetermined threshold more quickly. Since the outlet pressure of the boost pump 20 can reach the predetermined value more quickly, the cleaning fluid can enter the inner wall of the needle 40 more quickly, achieving efficient cleaning, reducing waiting time, and improving work efficiency.

[0038] like Figure 2 As shown, in some embodiments, the needle cleaning system of the analyzer also includes a boost diverter 80 and a boost reflux valve 70, the boost diverter 80 has an inlet, a first outlet and a second outlet, the inlet is connected to the boost pump 20, the first outlet can be connected to the liquid inlet end of the multi-way valve 30, and the second outlet can be connected to the liquid supply component 10 through the boost reflux valve 70; when the inner walls of the first reagent needle 411, the second reagent needle 412 and the sample needle 42 of a diverter component are to be cleaned, in the diverter component to be cleaned, the first valve body 61, the second valve body 62 and the third valve body 63 are first closed, the boost reflux valve 70 is opened, and after the outlet pressure of the boost pump 20 meets the predetermined threshold, the first valve body 61, the second valve body 62 and the third valve body 63 are opened again, and the boost reflux valve 70 is closed. Compared to providing a corresponding boost return valve 70 in each diversion component, the present embodiment can use only a single boost return valve 70. Reducing the number of boost return valves 70 can simplify the system design and reduce the complexity of the system. This helps to reduce potential failure points and improve the reliability of the system. Using fewer components can reduce production and maintenance costs. The material and installation costs of each boost return valve 70 can be accumulated, which will directly reduce the overall cost. In addition, there are fewer components in the system, maintenance and repair work becomes simpler, and operators can identify and deal with problems more quickly.
