The input end of the electric equipment in the equipment is electrically connected with an external power supply, and the equipment is provided with an operation panel of an embedded software automatic operation system.
Before the power is switched on and started, the soft endoscope tool is firstly connected with a biopsy port or a gas port water gap to ensure that the soft endoscope tool, a connector and a catheter are completely unobstructed without leakage, and simultaneously, the gas hole or the water inlet hole of the handle part and the on-line part of the endoscope are closed, if the connection part is the gas hole and the water inlet hole, the biopsy port can be closed firstly, only one hole at the tip part of the soft endoscope is unobstructed in principle, so that various liquids are poured into the endoscope, the smooth unobstructed state is ensured, enzyme liquid, flushing liquid, alcohol and gas are washed to circularly flow out, similarly, after an embedded driving program of the soft endoscope power cleaning brush is started, when the soft endoscope power cleaning brush is repeatedly pumped back and forth, a brush head is extended from the front end, and is repeatedly pumped back and forth again, and the effect of thoroughly cleaning the snake-shaped part and the front end tube cavity is achieved. If the duodenoscope is used, the forceps-lifting device needs to be opened manually or automatically according to an embedding program, and the brush can thoroughly brush the channel part of the forceps-lifting device at the moment.
After the power switch is turned on, the whole integral embedded cleaning software system is started, and after the cleaning program is started, the software program operation requirements are as follows: the valve 42 of the connection pipe 9 is closed to prevent the reverse flow of the liquid. Firstly, according to different cleaning stages and different requirements, when liquid or gas passes through, the one-way valves 41 of the connecting pipes 10 on the connector 9 are respectively and automatically opened, the one-way valves do not need to be controlled by a software system, and the washing enzyme liquid, the disinfectant, the purified water and the compressed gas respectively pass through the valves on the respective connecting pipes 10 and are filled into the cavity of the soft endoscope through the connector 9. Software programs for injecting various liquids or gases are initiated on demand. For example, after the injection program of the washing enzyme solution injection pump or the running water injection pump is started, the injected washing enzyme solution or water automatically enters the lumen of the soft endoscope through the one-way valve 41 and the one end of the connector 9. The filling of the washing enzyme liquid mainly has two functions, one is that dirt in the lumen of the soft endoscope can be removed, and the soft endoscope power cleaning brush can be lubricated, so that the soft endoscope power cleaning brush can easily and smoothly enter the soft endoscope, and then the soft endoscope power cleaning brush can conveniently do various reciprocating motions to achieve the purpose of thoroughly cleaning the cavity of the soft endoscope.
The software program controls the valve 42 to be in the closed state at this time to prevent the liquid or gas from flowing back into the washing brush storage tube 8 through the connection tube 9 and further flowing back to the drive unit 1 to pollute the environment. After the cleaning enzyme solution is filled, the software program starts the motor 22 of the driving device 1, each gear and the fixed wire pressing wheel 21 start to start and rotate according to the embedded program, when the threading steel wire 50 is driven to move, the valve 42 is opened in the design software program, the threading steel wire 50 firstly passes through the male connector 6 and the female connector 7 and enters the cleaning brush storage pipe 8, and meanwhile, the soft endoscope power cleaning brush which is connected with the threading steel wire 50 in advance and is placed in the cleaning brush storage pipe 8 in advance is pushed. The soft endoscope power cleaning brush enters the tube cavities of the connector 9 and the connecting tube, and is connected with the soft endoscope tool guide tube 48 and the soft endoscope tool 49, and the efficient cleaning of the soft endoscope power cleaning brush in the soft endoscope tube is completed according to a design procedure through a biopsy opening or a steam port water gap of the soft endoscope.
When the motor 22 for pushing the threading steel wire 50 operates according to a program, the rotating shaft is driven to rotate, the wire pressing wheel is driven by the multiple sets of gears, the whole rotation can implement positive rotation and reverse rotation according to a software program, the purpose is to realize that the soft endoscope power cleaning brush inserts and withdraws two sets of movements in the soft endoscope cavity, the friction force between the brush and the lumen wall can be ensured, and the coming meeting direction and the back-and-forth brushing times for cleaning the brush can be limited. The speed of the motor thrust is steady and powerful, i.e. to improve the stability of the washing brush when moving. The brush cleaning machine has the characteristics of enough power of the design machine and automatic control of software, can completely ensure the smooth retraction and release of the cleaning brush, saves time and reduces the labor intensity of cleaning personnel. On the whole 1600-inch 2200 mm-long soft endoscope power cleaning brush, a section of hair body with the length of 5-100 mm is arranged at intervals of 20-600mm, so after the soft endoscope power cleaning brush enters the cavity, the driving device 1 can continuously and alternately rotate forwards and backwards for more than 5 times according to a software program, the continuously and alternately rotating forwards and backwards ensures that the back-and-forth movement distance of the soft endoscope power cleaning brush in the soft endoscope cavity is about 20-700mm (the time required for one reciprocating is designed and can be based on the principle that the operation speed and the operation time are the operation distance), thus ensuring that each part of the whole cavity can be completely and fully cleaned, and avoiding that the cleaning blind spot in the lumen is not completely cleaned.
The reciprocating washing movement of the soft endoscope power washing brush is driven by the movement of the threading steel wire 50 connected with the soft endoscope power washing brush, and the movement of the threading steel wire 50 is implemented by the thrust generated by the extrusion and rotation of the fixed wire pressing wheel 21 of the driving device. The length of the threading steel wire 50 is generally 400-3000mm, and the diameter, softness and toughness of the threading steel wire are selected according to the power requirements.
After the soft endoscope power cleaning brush finishes cleaning according to the required cleaning times and time, the threading steel wire 50 is wound out of the cleaning brush storage tube 8 under the compression driving of the fixed wire pressing wheel 21 of the driving device 1 in the set software program design, at this time, the roller wire coil 15 also helps to wind up and retract the threading steel wire 50 along with the rotation of the roller, and the soft endoscope power cleaning brush also automatically retracts into the cleaning brush storage tube 8 according to the set program.
After the filling of the washing enzyme liquid and the reciprocating washing of the soft endoscope power cleaning brush are successively completed according to the program, the embedded software program starts pure water washing according to the program, and then starts a compressed air blowing program to blow and dry the tube cavity of the soft endoscope. Also, when the liquid filling or air blow-drying process is initiated, the valve 42 is programmed to be closed.
If the disinfection program is selected for the disinfection liquid, the disinfection cleaning button is pressed. The required design program and the implementation process are similar to those of enzyme cleaning liquid, and the difference is that the soaking time of different disinfectant is different, and the disinfection time required by design is different from the filling time of the cleaning enzyme. The washing and drying procedures required for disinfection and cleaning are similar to the washing and drying procedures after cleaning with cleaning enzyme.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
