Endoscope is a commonly used medical device, which is divided into rigid endoscope and soft endoscope. Rigid endoscope generally enters sterile tissues and organs or enters human sterile chamber through surgical incision; flexible endoscope (such as gastrointestinal Flexible endoscopes such as endoscopes, bronchoscopes, laryngoscopes, nasopharyngoscopes, and choledochoscopes) generally enter the digestive tract and respiratory tract and come into contact with mucous membranes. Since the pipeline cleanliness of the endoscope cleaning machine is directly related to the cleaning effect of the endoscope, the cleaning and disinfection of the endoscope is very strict. Clinically, after the endoscope is used, a special endoscope cleaning machine will be used to complete the cleaning task of the endoscope with narrow and long channels through multiple cleaning processes (such as water washing-enzyme washing-water washing-disinfectant washing-water washing).

A preferred solution of the present invention, wherein, both the enzyme liquid delivery pipeline and the alcohol delivery pipeline are provided with pinch valves.

Working principle of the present invention is:

The endoscope cleaning process is divided into multiple steps. The conventional cleaning process is water washing (also called initial washing)-enzyme washing-water washing (also called secondary washing)-disinfectant washing-water washing (also called final washing) Five major steps, among which, water washing refers to cleaning with clean water (the water used in the cleaning of the disinfection machine is pure water, not ordinary tap water) for cleaning, enzyme washing refers to mixing enzyme liquid and clean water into a cleaning liquid for cleaning, and disinfectant Washing refers to cleaning with disinfectant. In each step, the cleaning solution (clear water, enzyme cleaning solution or disinfectant) is first filled into the cleaning tank, and then the internal circulation and external circulation cleaning processes are started. After each step is completed, the cleaning solution must be discharged from the cleaning tank , and then inject the cleaning solution used in the next step.

Taking water washing as an example, before cleaning, first connect the endoscope tube to the flushing connector, then close the sealing cover, and start to inject water into the cleaning tank. Specifically, the action of water injection is: the control system controls the opening of the water inlet electric valve, and the water flow After being conveyed by the first branch water pipe and the water inlet and outlet main pipes, it is sprayed from the water inlet and outlet into the cleaning tank. With the continuous delivery of water, the water level of the cleaning tank continues to rise until the cleaning water fills the entire cleaning tank, and the water inlet action stops. . Since the water level in the cleaning tank has filled the sealed cavity formed by the cleaning tank and the sealing cover, the inner wall of the sealing cover can be fully soaked, so the sealing cover can be sterilized, thereby avoiding secondary pollution of the endoscope due to the growth of bacteria.

After completing the water injection task, the control system controls the opening of the internal circulation valve, and the internal circulation pump starts to work, pumping out the water in the cleaning tank through the water inlet and outlet, transporting it to the flushing joint through the second branch water pipe, and spraying it into the endoscope tube , and finally flow from the endoscopic tube to the cleaning tank, so that the water flow forms a circulating flow between the second branch water pipe, the endoscopic tube and the cleaning tank, and the task of flushing the endoscopic tube is constantly carried out in the flow. At the same time, the control system controls the operation of the external circulation pump, pumps the water in the cleaning tank through the drain outlet, and sprays it into the cleaning tank through the main drainage pipe, external circulation pipe and circulation nozzle, thereby forming an external circulation flow, which is good for the inner mirror. Clean the surface with fluidity. On the one hand, the flowing water on the surface of the endoscope can promote the cleaning of the surface of the endoscope. On the other hand, it can prevent the pollutants in the cleaning tank from adhering to the wall of the cleaning tank, avoiding damage to Subsequent cleaning is hindered.

When performing enzyme washing, the enzyme liquid supply device transports the enzyme liquid to the flushing joint through the second branch water pipe, sprays it into the endoscope tube, and then flows from the endoscope tube into the cleaning tank. The concentration requires a certain amount of enzyme liquid to be delivered, and then to pass clean water into the cleaning tank. The process of passing clean water is the same as the above-mentioned washing process, followed by internal circulation and external circulation of cleaning liquid. It is mixed with the enzyme solution in the pipeline to form an enzyme cleaning solution, and the subsequent internal circulation operation and external circulation operation process are the same as the above water washing process.

When washing with disinfectant, the control system controls the start of the disinfectant suction pump, and transports the disinfectant in the disinfectant storage tank to the cleaning tank through the disinfection delivery pipeline until the entire cleaning tank is filled. Subsequently, the cleaning operation of the inner circulation and the outer circulation is carried out synchronously, which is the same as the above water washing process.

After the cleaning operation of each step is completed, the cleaning liquid needs to be discharged, which is completed by the control system controlling the three-way valve. In the stages of water washing and enzyme washing, the three-way valve is controlled to allow the cleaning liquid to be discharged to the outside through the drainage pipe. In the cleaning stage, the three-way valve is controlled to allow the cleaning solution to be recycled into the disinfectant storage tank for reuse.

Compared with the prior art, the present invention has the following beneficial effects:

1. The cleaning method of the full immersion endoscope cleaning machine of the present invention is by setting the water inlet of the cleaning tank (that is, the water inlet and outlet) on the wall of the clear water tank, and sealing the cleaning tank through the sealing cover when injecting water, which can make The water level in the cleaning tank is filled with the sealing cavity formed by the cleaning tank and the sealing cover, completely soaking the inner wall of the sealing cover, so that the inner wall of the sealing cover can participate in the whole cleaning and disinfection process, and complete the disinfection task, thus avoiding damage caused by the growth of bacteria Secondary pollution to the endoscope. In addition, the water inlet and outlet itself and the flushing connector are also completely immersed in the cleaning solution, so that all parts in the cleaning tank can be cleaned and disinfected, thereby completely eliminating dead ends for disinfection and realizing comprehensive cleaning and disinfection.

1. In the cleaning method of the full immersion type endoscope cleaning machine of the present invention, only one water inlet and outlet is provided, and the task of water injection in the cleaning tank and the task of pumping water in the inner circulation of the water flow can be respectively completed according to the requirements. As far as the water injection port and the water pumping port are set separately, the advantage is that in the process of disinfecting or enzymatic cleaning the endoscope tube with the disinfectant or enzyme cleaning solution, since the water inlet and outlet have the function of pumping water, the disinfectant will be drained during the pumping process. It can flow through the water inlet main pipe, so that the water inlet main pipe can be disinfected, and the secondary pollution of the endoscope cleaning caused by the growth of bacteria on the water inlet main pipe can be avoided; Therefore, the main water pipe cannot be disinfected because the disinfectant cannot flow through the water injection pipe during the circulation process, which may cause the water injection pipe to damage the endoscope due to the growth of bacteria. The cleaning produces secondary pollution, which reduces the effect of cleaning and disinfection. In addition, setting the water injection port and the water suction port as one water inlet and outlet can simplify the structure of the cleaning tank and reduce installation and manufacturing costs.

, The cleaning method of the full immersion endoscope cleaning machine of the present invention pumps the water flow from the drain port to the circulation nozzle through the external circulation pump, and sprays it from the circulation nozzle. The water flow that is sprayed can generate disturbance water waves to the water in the cleaning tank On the one hand, the water wave can promote the cleaning of the surface of the endoscope, and on the other hand, it can prevent the pollutants in the cleaning tank from adhering to the wall of the cleaning tank, so as to avoid hindering the subsequent cleaning.

Referring to Fig. 1-Fig. 4, the working principle of the cleaning method of the full immersion endoscope cleaning machine in this embodiment is:

The endoscope cleaning process is divided into multiple steps. The conventional cleaning process is water washing-enzyme washing-water washing-disinfectant washing-water washing. Pure water (not ordinary tap water) is used for cleaning. Enzyme washing refers to mixing enzyme liquid and clear water into a cleaning solution for cleaning. Disinfectant washing refers to cleaning by passing in disinfectant. In each step, the cleaning solution (clear water, enzyme cleaning solution or disinfectant) is first filled into the cleaning tank 1a, and then the internal circulation and external circulation cleaning processes are started. After each step is completed, the cleaning solution must be discharged for cleaning Tank 1a, and then inject the cleaning solution used in the next step.

Taking water washing as an example, before cleaning, firstly connect the endoscope tube to the flushing connector 3a, then close the sealing cover 2a, and start to inject water into the cleaning tank 1a. Specifically, the water injection action is: the control system controls the water inlet electric valve 9 is opened, and after the water flows through the first branch water pipe 2 and the water inlet and outlet main pipe 6, it is sprayed from the water inlet and outlet 7a into the cleaning tank 1a. With the continuous delivery of water, the water level of the cleaning tank 1a continues to rise until the cleaning water The whole cleaning tank 1a is full, and the water inlet action stops. Because the water level in the cleaning tank 1a has been filled with the sealed cavity formed by the cleaning tank 1a and the sealing cover 2a, the inner wall of the sealing cover 2a can be fully soaked, so the sealing cover 2a is sterilized, thereby avoiding the endoscope due to the growth of bacteria secondary pollution.

After the water injection task is completed, the control system controls the internal circulation valve 11 to open, and the internal circulation pump 10 starts to work, and the water in the cleaning tank 1a is drawn out through the water inlet and outlet 7a, and is transported to the flushing joint 3a through the second branch water pipe 7, and sprayed. into the endoscopic tube, and finally flow from the endoscopic tube to the cleaning tank 1a, so that the water flow forms a circulating flow between the second branch water pipe 7, the endoscopic tube and the cleaning tank 1a, and continuously Follow the task of flushing the endoscopic tube. At the same time, the control system controls the operation of the external circulation pump 20, pumps the water in the cleaning tank 1a through the drain port 8a, and sprays it into the cleaning tank 1a through the drain main pipe 5, the external circulation pipeline 19 and the circulation nozzle 4a, thereby forming an external Circulating flow to clean the surface of the endoscope. On the one hand, the flowing water on the surface of the endoscope can promote the cleaning of the surface of the endoscope, and on the other hand, it can prevent the pollutants in the cleaning tank 1a from adhering to the wall of the cleaning tank 1a to avoid hindrance to the subsequent cleaning.

When performing enzyme washing, the enzyme liquid supply device transports the enzyme liquid to the flushing connector 3a through the second branch water pipe 7, sprays it into the endoscope tube, and delivers a certain amount of enzyme liquid according to the concentration of the enzyme cleaning liquid. Then feed clean water into the cleaning tank 1a, the process of feeding clean water is the same as the above-mentioned washing process, and then perform internal circulation and external circulation cleaning liquid operations, wherein, during the initial internal circulation, the clean water and the enzyme liquid in the pipeline are mixed into Enzyme cleaning solution, subsequent internal circulation operation and external circulation operation process are the same as the above-mentioned water washing process.

When performing disinfectant washing, the control system controls the disinfectant suction pump 12 to start, and the disinfectant in the disinfectant storage tank 14 is transported to the cleaning tank 1a through the disinfection delivery pipeline 3 until the entire cleaning tank 1a is filled. Subsequently, the cleaning operation of the inner circulation and the outer circulation is carried out synchronously, which is the same as the above water washing process.

After the cleaning operation of each step is completed, the cleaning liquid needs to be discharged, which is specifically completed by the control system to control the three-way valve 15. In the stages of water washing and enzyme washing, the three-way valve 15 is controlled to allow the cleaning liquid to be discharged to the outside through the drain pipe 42. In the stage of cleaning the disinfectant, the three-way valve 15 is controlled to allow the cleaning solution to be recovered into the disinfectant storage tank 14 for reuse.

In addition, after the cleaning operation of each step is completed, in order to avoid the residual liquid in the pipeline from affecting the cleaning of the next step, a blow-drying operation process is started, specifically starting the blow-drying pump 29, through the ventilation pipe 28 to the first The two branch water pipes 7 and the endoscope are blown to dry up the remaining liquid. In the present invention, drying with alcohol is an optional step after drying the unwashed ones.

The above is a preferred embodiment of the present invention, but the embodiment of the present invention is not limited by the above content, and any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention are all Replacement methods that should be equivalent are all included within the protection scope of the present invention.
