Description

Technical Field

[0001] The invention belongs to the technical field of endoscopes, and in particular relates to a digestive endoscope cleaning device. Background Art

[0002] A digestive endoscope is a medical device used to examine and treat digestive system diseases. It is mainly inserted through the natural cavity of the human body (such as the mouth, anus, etc.) to directly observe the internal conditions of the digestive tract, such as the esophagus, stomach, duodenum, small intestine, and large intestine.

[0003] During the examination or treatment process, the digestive endoscope will come into contact with the patient's blood, tissue, mucus and various secretions. These substances may contain a large number of pathogenic microorganisms, such as bacteria (including Staphylococcus aureus, Escherichia coli, etc.), viruses (such as hepatitis B virus, hepatitis C virus, HIV, etc.) and fungi. If they are not cleaned, when the next patient uses the same endoscope, these pathogenic microorganisms will be transmitted to them, causing serious infectious diseases. Therefore, cleaning of the digestive endoscope is a very important work process, such as the digestive endoscope cleaning device proposed in the patent announcement number CN114027774A.

[0004] Currently, the cleaning of digestive endoscopes requires four processes: multi-enzyme solution immersion treatment, water washing, disinfection and final water washing. The four processes are carried out separately, which greatly affects the cleaning efficiency. In addition, it is difficult to clean the biopsy channel and suction channel on the digestive endoscope, which makes it easy for the channel to be blocked, affecting the cleaning effect. In the cleaning process, manual operation by staff is prone to damage the endoscope due to improper operation, such as excessive force, use of inappropriate tools, etc., resulting in great economic losses.

[0042] The PLC controller 9 is fixedly mounted on the workbench 1 and is electrically connected to the multi-stage flushing and cleaning mechanism 3, the channel unblocking mechanism 4, the cleaning step control mechanism 5 and the pollution degree input feedback regulating mechanism 6 respectively.

[0043] The operating principle of the present invention is described as follows: the insertion portion of the endoscope body 10 to be cleaned is first relatively placed in the two positioning fixtures 23, so that the biopsy channel and the suction channel on the endoscope body 10 are aligned with the two positioning nozzles 22 on the side wall of the hollow contact plate 21, so as to achieve accurate positioning of the endoscope body 10, and then the positioning fixture 23 is locked, and the endoscope body 10 is fixed by the positioning fixture 23 to ensure the fixation stability of the endoscope body 10;

[0044] First, the multi-enzyme liquid immersion cleaning work is carried out. The PLC controller 9 controls the electric push rod 36 to push the water shield 37 downward, so that the sealing pad at the lower end of the water shield 37 is in sealing contact with the bottom of the inner wall of the cleaning tank 8, and a separate sealed cleaning space is formed outside the endoscope body 10. The PLC controller 9 opens the first multi-way pipe 39 and the second multi-way pipe 312, which are respectively connected to the first solenoid valve 311 and the second solenoid valve 314 on the multi-enzyme cleaning liquid tank 31, and controls the first water pump 310 and the second water pump 313 to work. The first water pump 310 transports the multi-enzyme cleaning liquid in the multi-enzyme cleaning liquid tank 31 to the sprayer 38, and the multi-enzyme cleaning liquid is sprayed on the outside of the endoscope body 10 through the sprayer 38. The second water pump 313 transports the multi-enzyme cleaning liquid to the hollow resistance plate 21, and sprays it out through the positioning nozzle 22, so that the multi-enzyme cleaning liquid flows through the biopsy channel and the suction channel of the endoscope body 10. The use of multi-enzyme cleaning solution can effectively remove contaminants such as attached mucus, blood and tissue fragments, preliminarily decompose organic matter, and lay the foundation for subsequent cleaning steps. As more and more multi-enzyme cleaning solution is injected into the sealed cleaning space formed by the water retaining cover 37 outside the endoscope body 10, the water of the multi-enzyme cleaning solution will gradually rise, and the multi-enzyme cleaning solution will generate a buoyancy on the floating plate 71, and the floating plate 71 drives the lifting plate 72 to move up synchronously until the lifting plate 72 presses on the in-place switch 75. At this time, the PLC controller 9 controls the first water pump 310 and the second water pump 313 to stop working, so that the endoscope body 10 continues to be immersed in the multi-enzyme cleaning solution. After the immersion is completed, the PLC controller 9 controls the electric push rod 36 to drive the water retaining cover 37 to move up 10 cm, so that the bottom of the water retaining cover 37 is separated from the bottom of the inner wall of the cleaning tank 8, so that the injected multi-enzyme cleaning solution is discharged through the sewage outlet of the cleaning tank 8;

[0045] Then, the clean water flushing stage is entered, and the PLC controller 9 controls the first solenoid valve 311 and the second solenoid valve 314 at the clean water tank 32 corresponding to the first multi-way pipe 39 and the second multi-way pipe 312 to open, and the first pump 310 and the second pump 313 are used to flush the outer surface of the endoscope body 10 and the biopsy channel and the suction channel with clean water. The flowing clean water flushing ensures that the multi-enzyme cleaning solution and pollutants are completely flushed away, and in the flushing process, the PLC controller 9 controls the drive motor 43 and the bidirectional motor assembly 46 to act synchronously, and the bidirectional motor assembly 46 drives the two rotating rods 45 to drive the bristle tube 47 to rotate synchronously, and the drive motor 43 drives the reciprocating screw rod 42 to rotate, and the reciprocating plate 44 drives the rotating rod 45 and the bristle tube 47 to move back and forth through the threaded sleeve effect of the reciprocating screw rod 42 and the reciprocating plate 44, and the two bristle tubes 47 enter the biopsy channel and the suction channel respectively, and further clean the inner walls of the two channels to ensure the flushing quality;

[0046] After the clean water flushing work is completed, the disinfectant flushing stage begins. The PLC controller 9 opens the first solenoid valve 311 and the second solenoid valve 314 on the first multi-way pipe 39 and the second multi-way pipe 312 corresponding to the position of the disinfectant tank 33, and the disinfectant is applied to the endoscope body 10 under the operation of the first water pump 310 and the second water pump 313 to perform the disinfection operation. In this stage, the PLC controller 9 also controls the electric push rod 36 to push the water shield 37 downward, and again forms a closed disinfection space outside the endoscope body 10 until the amount of disinfectant injected is sufficient. After the rising water level causes the lifting plate 72 to press on the in-place switch 75, the PLC controller 9 controls the first water pump 310 and the second water pump 313 to stop the action and stop continuing to deliver the disinfectant, so that the disinfectant completely immerses the endoscope body 10, ensuring that all parts of the endoscope body 10 are fully in contact with the disinfectant.

[0047] After the disinfection work is completed, the final water washing stage is entered, and the PLC controller 9 controls the electric push rod 36 to drive the water shield 37 to move upward to discharge the accumulated disinfectant, and controls the first multi-way pipe 39 and the second multi-way pipe 312 to open the first solenoid valve 311 and the second solenoid valve 314 on the sterile water tank 34, and uses sterile water to comprehensively wash the outer surface of the endoscope body 10 and the inside of the biopsy channel and the suction channel therein to remove the residual disinfectant on the endoscope body 10 to prevent the disinfectant from causing irritation or damage to the patient, until the disinfectant is completely washed away, and the entire disinfection work is completed;

[0048] And in the cleaning work of the endoscope body 10, the PLC controller 9 synchronously controls the action of the reduction motor 53, the reduction motor 53 drives the transmission screw 52 to rotate, and the synchronous seat 54 is continuously moved through the threaded sleeve action of the transmission screw 52 and the synchronous seat 54. When the round head part of the synchronous seat 54 presses on the clean water flushing start switch 55, it indicates that the flushing and soaking work of the multi-enzyme cleaning solution is completed, and the PLC controller 9 controls the multi-stage flushing and cleaning mechanism 3 to enter the second stage of clean water flushing. When the round head part of the synchronous seat 54 presses on the disinfection start switch 56, the PLC controller 9 controls the multi-stage flushing and cleaning mechanism 3 to enter the third stage of disinfectant flushing and soaking. When the round head part of the synchronous seat 54 presses on the sterile water flushing start switch 57, the PLC controller 9 controls the multi-stage flushing and cleaning mechanism 3 to enter the fourth stage of the final flushing work, until the synchronous seat 54 presses on the completion stop switch 58, it indicates that the entire cleaning work is completed, and the staff is promptly reminded to carry out subsequent processing;

[0049] Before cleaning the endoscope body 10, the inspector directly observes the inner and outer surfaces of the endoscope body 10 to see whether there are obvious contaminants such as blood, tissue fragments, mucus, etc., so as to determine the degree of contamination. For example, if there are a lot of blood stains on the surface of the endoscope body 10, or there are residual tissues around the biopsy channel, it can be judged that the degree of contamination is serious. The staff drives the adjustment screw 62 to rotate by the hand crank 63, and the adjustment seat 64 drives the identification rod 66 to move through the threaded sleeve effect of the adjustment screw 62 and the adjustment seat 64, until the movement position of the identification rod 66 relative to the contamination indicator plate 65 reaches the contamination degree estimated by the staff, and then stops moving the adjustment seat 64. In the process of moving the adjustment seat 64, the first feedback conductive contact 69 and the second feedback conductive contact 610 are driven to slide synchronously on the first feedback resistor rod 67 and the second feedback resistor rod 68. Specifically, the greater the degree of contamination judged for the endoscope body 10, the greater the distance the adjustment seat 64 moves, so that the first feedback conductive contact 69 and the second feedback conductive contact 610 are moved separately. The greater the sliding distance on the first feedback resistor rod 67 and the second feedback resistor rod 68, the greater the access resistance of the first feedback resistor rod 67 and the smaller the access resistance of the second feedback resistor rod 68. The first feedback conductive contact 69 and the second feedback conductive contact 610 are connected in series to the power supply circuit of the reduction motor 53, and the reduction motor 53 is a DC motor. Therefore, the power supply current of the reduction motor 53 becomes smaller, and the speed of the reduction motor 53 is slower, thereby making the cleaning work time of each stage longer, ensuring the cleaning quality. The second feedback conductive contact 610 and the second feedback resistor rod 68 are connected in series to the power supply circuit of the first water pump 310 and the second water pump 313, and the first water pump 310 and the second water pump 313 are both DC pumps. Therefore, in the case of a large degree of pollution, the power supply current of the first water pump 310 and the second water pump 313 will become larger, thereby increasing the working power of the first water pump 310 and the second water pump 313, increasing the flushing pressure, and ensuring that the pollutants can be fully and completely flushed away, thereby ensuring the flushing quality.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
