In other embodiments, the receiving tank 20 could be disposed with a stirrer to stir the fluid in the receiving tank 20, thereby accelerating a decontaminating process of the tube body E2, namely making contaminants be disengaged from the inner surface or the outer surface of the tube body E2 faster.
Referring to
Step S101: put the tube body E2 of the endoscope E into the receiving tank 20. Referring to
Step S102: manipulate the operating module 40 to control the circulating module 30 to initiate an automatic cleaning process, wherein the automatic cleaning process includes executing at least one disinfecting step and at least one cleansing step. The disinfecting step includes transmitting the solution of the source of first solution supply S1 to the receiving tank 20 to allow the tube body E2 being soaked into the solution outputted from the source of first solution supply S1, and then discharge the solution in the receiving tank 20 out of the receiving tank 20. The cleansing step includes transmitting a solution of the source of second solution supply S2 to the receiving tank 20 to allow the tube body E2 being soaked into the solution outputted from the source of second solution supply S2, and then discharge the solution in the receiving tank 20 out of the receiving tank 20.
For example, after the user conduct the step S101, the user could press the power button 421 on the operating panel 42 to power up the endoscope cleaning device 1, and then press the initiate button 422 of the operating panel 42 to drive the endoscope cleaning device 1 to automatically conduct the automatic cleaning process. In the current embodiment, the endoscope cleaning device 1 carries on the disinfecting step once at first. More specifically, a predetermined volume of a disinfection solution of the source of first solution supply S1 is transmitted to the receiving tank 20 by the first pump 31 through the tube T1 to allow the tube body E2 to be soaked in disinfection solution for a first predetermined time, and then the second pump 32 pumps the disinfection solution in the receiving tank 20 to the first storage tank 35 via the tube T3, thereby allowing the disinfection solution completely discharged from the receiving tank 20. After that, the endoscope cleaning device 1 carries on the cleansing step once. More specifically, a predetermined volume of the water of the source of second solution supply S2 is transmitted to the receiving tank 20 by the third pump 33 via the tube T2 to allow the tube body E2 to be soaked in the water outputted from the source of second solution supply S2 for a second predetermined time, and then the fourth pump 34 pumps the water in the receiving tank 20 to the second storage tank 36, thereby allowing the water to be complete discharged from the receiving tank 20. Finally, the endoscope cleaning device 1 carries on the cleansing step again to ensure that pollutants, contaminants, and the disinfection solution remained on the tube body E2 could be completely cleaned or washed away. It's worthy to mention that when the user press the initiate button 422 on the operating panel 42, the display screen 70 shows a time that needs for completing the automatic cleaning process and starts to countdown the time, so that the user could realize the time that needs for completing the automatic cleaning process from reading the time shown on the display screen 70. Additionally, in the current embodiment, the endoscope cleaning device 1 includes a level sensor 90 which is connected to the receiving tank 20. Before either the disinfecting step or the cleansing step, the level sensor 90 senses a liquid level of the solution in the receiving tank 20. When the liquid level of the solution in the receiving tank 20 is higher than a detecting position of the level sensor 90, the first pump 31 or/and the third pump 33 is prohibited to pump the solution of source of first solution supply S1 or the solution of the source of second solution supply S2 to the receiving tank 20, thereby preventing the solution from overflowing the receiving tank 20.
In the current embodiment, the automatic cleaning process sequentially conducts the disinfecting step once and the cleansing step twice as an example. In other embodiment, the automatic cleaning process could include the disinfecting step and the cleansing step once or more than once. Besides, the sequence of the disinfecting step and the cleansing step does not limited to conduct the disinfecting step first, and then conduct the cleansing step. For example, the automatic cleaning process could sequentially conduct the cleansing step once, the disinfecting step once, and cleansing step once.
Furthermore, the cleaning method of the endoscope includes operating the operating module 40 to control the circulating module 30 to initiate a compulsorily draining disinfecting solution step. The compulsorily draining disinfecting solution step includes draining the solution in the receiving tank 20 out of the receiving tank 20. For example, when the first pump 31 transmits the disinfection solution of the source of first solution supply S1 to the receiving tank 20 via the tube T1, the user could press the button 423 for compulsorily draining disinfecting solution on the operating panel 42 to stop the first pump 31 and initiate the second pump 32 to drain the disinfection solution in the receiving tank 20 to the first storage tank 35, thereby completely draining out the disinfection solution from the receiving tank 20. Besides, when the third pump 33 transmits the water of the source of second solution supply S2 to the receiving tank 20 via the tube T2, the user could press the button 424 for compulsorily draining water on the operating panel 42 to control the fourth pump 34 to pump the water in the receiving tank 20 to the second storage tank 36 through tube T4, thereby completely draining the water in the receiving tank 20.
The cleaning method of the endoscope includes at least one predetermined time to control an activation of the ultrasonic vibrator 80, wherein the at least one predetermined time includes a first predetermined time or a second predetermined time. In other words, when the tube body E2 is soaked in the disinfection solution or the water, the ultrasonic vibrator 80 could apply an ultrasonic vibration to the solution in the receiving tank 20, thereby sufficiently and completely cleaning, disinfecting, and sterilizing the outer surface and the inner surface of the tube body E2.
In view of above, by using the endoscope cleaning device and the cleaning method of the endoscope of the embodiment according to the present invention, the endoscope cleaning device could automatically conduct the automatic cleaning process to make the cleaning process of the endoscope be standardized and simplified, thereby enhancing the cleaning efficiency and cleaning quality.
It must be pointed out that the embodiment described above is only a preferred embodiment of the present invention. All equivalent structures and methods which employ the concepts disclosed in this specification and the appended claims should fall within the scope of the present invention.
