Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically, to a gastroscopy system and its application method that integrates air delivery, water delivery and suction control functions. Background Technology

[0002] A gastroscopy is a medical device used to examine lesions in the upper digestive tract (esophagus, stomach, and duodenum). A flexible endoscope with a camera at the tip is inserted through the mouth, transmitting real-time images to a monitor for the doctor's observation. Current gastroscopy systems use two purely mechanical valves connected to control the suction tube and air / water tubing, respectively. This mechanical valve design suffers from the drawback of the valve material's aging tendency: frequent use (e.g., more than 20 times per day) can lead to elastic fatigue of the rubber seals or plastic valve bodies, resulting in air / water leakage and insufficient suction. Furthermore, existing gastroscopy systems require an additional negative pressure generator for suction, which is inconvenient. Therefore, a new gastroscopy system and application method integrating air / water delivery and suction control functions is urgently needed to address these industry pain points. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a gastroscopy system that integrates air delivery, water delivery and suction control functions, and to provide a method for applying the gastroscopy system that integrates air delivery, water delivery and suction control functions, in view of the above-mentioned defects of the prior art.

[0004] The technical solution adopted by this invention to solve its technical problem is:

[0005] A method for constructing and applying a gastroscopy system integrating air delivery, water delivery, and suction control functions is provided. The gastroscopy system comprises an operating handle and a control unit connected via integrated tubing. The application method includes the following steps:

[0006] When the air supply button on the control handle is triggered, an air supply command is generated and sent to the control host; when the water supply button on the control handle is triggered, a water supply command is generated and sent to the control host; when the suction button on the control handle is triggered, a suction command is generated and sent to the control host.

[0007] The control host receives commands sent by the operating handle and identifies the command type;

[0008] If the instruction type is a water delivery instruction, then the water delivery unit is controlled to operate: the water delivery solenoid valve opens, and the water delivery pump runs to deliver water from the water bottle to the operating handle through the water delivery pipeline in the integrated pipeline.

[0009] If the command type is a gas delivery command, the gas delivery unit is controlled to operate: the gas delivery solenoid valve opens, and the gas delivery pump operates to deliver gas to the operating handle through the gas delivery pipeline in the integrated pipeline.

[0010] If the command type is a suction command, the suction unit is controlled to operate: the suction solenoid valve opens, and the negative pressure pump operates to send water from the negative pressure bottle to the operating handle through the suction pipeline in the integrated pipeline.

[0011] The method for applying the gastroscopy system integrating air delivery, water delivery, and suction control functions described in this invention further includes:

[0012] After receiving the instructions sent by the operating handle, the control host monitors the status of the water supply pipeline, air supply pipeline and suction pipeline accordingly.

[0013] Based on the feedback monitoring results, confirm whether the instructions have been accurately implemented.

[0014] The present invention relates to a method for applying a gastroscopy system integrating air delivery, water delivery, and suction control functions. The integrated tubing includes a sheath, within which a mounting bracket is provided for installing a water delivery tubing, an air delivery tubing, and a suction tubing. Each of the water delivery tubing, air delivery tubing, and suction tubing has an arc-shaped flexible tube segment. A monitoring unit is provided on the sheath, and the monitoring unit determines whether the tubing is currently in operation by monitoring whether the arc-shaped flexible tube segment vibrates.

[0015] The present invention describes an application method for a gastroscopy system integrating air delivery, water delivery, and suction control functions, wherein the mounting frame includes multiple positioning plates spaced apart from each other, and each positioning plate has three through holes for the water delivery pipe, air delivery pipe, and suction pipe to pass through respectively; the edge of the positioning plate is fixedly connected to the inner wall of the cannula.

[0016] The present invention describes an application method for a gastroscopy system integrating air delivery, water delivery, and suction control functions, wherein the monitoring unit includes a lamp body, a mounting rod, and three light sensors; three arc-shaped flexible tube segments are arranged around the lamp body, and the three light sensors are distributed around the periphery of the three arc-shaped flexible tube segments; the mounting rod is used to fix the lamp body to two adjacent positioning plates;

[0017] In the initial state, the light emitted by the lamp body is blocked by three curved flexible tube segments, so that the three light sensors cannot detect the light;

[0018] When any segment of the curved flexible tube vibrates, the corresponding optical sensor will continuously and intermittently detect light.

[0019] The control host determines whether the curved hose section is vibrating based on the electrical signal from the optical sensor, and then determines whether the pipeline is currently in operation.

[0020] An endoscopy system integrating air delivery, water delivery, and suction control functions is provided for implementing the aforementioned application method of an endoscopy system with integrated air delivery, water delivery, and suction control functions. The system includes an operating handle and a control host. The control host is equipped with a water delivery unit, an air delivery unit, a suction unit, and a main control board. The water delivery unit, air delivery unit, and suction unit are all connected to and controlled by the main control board. The water delivery unit, air delivery unit, and suction unit are respectively connected to the operating handle via corresponding pipelines. The operating handle is equipped with a sub-control board and a button unit. The sub-control board is electrically connected to the main control board and is used to send control commands from the button unit to the main control board. The main control board controls the water delivery unit, air delivery unit, and suction unit accordingly based on the commands. The button unit includes an air delivery button, a water delivery button, and a suction button. The operating handle is connected to the control host via an integrated pipeline, which includes a water delivery pipeline, an air delivery pipeline, and a suction pipeline.

[0021] The gastroscopy system integrating air delivery, water delivery, and suction control functions of the present invention includes an operating handle connected to the control host via an electronic signal transmission cable, which electrically connects the sub-control board to the main control board.

[0022] The gastroscopy system integrating air delivery, water delivery, and suction control functions of the present invention includes a water delivery unit comprising a water delivery bottle, a water delivery pump, and a water delivery solenoid valve; an air delivery unit comprising an air delivery pump and an air delivery solenoid valve; and a suction unit comprising a negative pressure pump, a negative pressure water bottle, and a suction solenoid valve.

[0023] The gastroscopy system integrating air delivery, water delivery, and suction control functions of the present invention includes an image processing circuit board and a display screen on the control host; the button unit also includes a photo control button.

[0024] The gastroscopy system integrating gas delivery, water delivery, and suction control functions of the present invention is further provided with a gas delivery switch button, a water delivery switch button, a suction switch button, and an indicator light assembly for indicating the gas delivery, water delivery, and suction status on the control host.

[0025] The beneficial effects of this invention are as follows: When the button on the operating handle is triggered by the method of this application, a corresponding instruction is generated and sent to the control host. The control host then provides corresponding feedback on air supply, water supply, or suction, thereby completing the control of air supply, water supply, and suction. The operation is simpler, while avoiding a series of defects of existing mechanical buttons. Attached Figure Description

[0045] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.

[0046] Example 1

[0047] A preferred embodiment of the present invention provides an application method for a gastroscopy system integrating air delivery, water delivery, and suction control functions, such as... Figure 1 As shown, see also Figures 2-17 The gastroscopy system consists of an operating handle and a control unit connected by an integrated tubing. The application method includes the following steps:

[0048] S01: When the air supply button on the operating handle is triggered, an air supply command is generated and sent to the control host; when the water supply button on the operating handle is triggered, a water supply command is generated and sent to the control host; when the suction button on the operating handle is triggered, a suction command is generated and sent to the control host.

[0049] S02: The control host receives the instructions sent by the operating handle and identifies the instruction type;

[0050] S03: If the instruction type is a water delivery instruction, then control the operation of the water delivery unit: the water delivery solenoid valve opens, and the water delivery pump runs to deliver water from the water bottle to the operating handle through the water delivery pipeline in the integrated pipeline.

[0051] S04: If the command type is a gas delivery command, then control the operation of the gas delivery unit: the gas delivery solenoid valve opens, and the gas delivery pump runs to deliver gas to the operating handle through the gas delivery pipeline in the integrated pipeline.

[0052] S05: If the instruction type is a suction instruction, then control the suction unit to operate: the suction solenoid valve opens, the negative pressure pump operates to send water from the negative pressure bottle to the operating handle through the suction pipeline in the integrated pipeline.

[0053] By applying the method of this application, when the button on the operating handle is triggered, a corresponding instruction is generated and sent to the control host. The control host then provides corresponding feedback on air supply, water supply, or suction, thereby completing the control of air supply, water supply, and suction. This makes the operation simpler and avoids a series of defects existing in mechanical buttons.

[0054] It should be noted that steps S03, S04, and S05 above are parallel steps and do not have a specific order; the structure for implementing this solution can be found in the solution in Example 3.

[0055] Example 2

[0056] This embodiment is basically the same as the previous embodiment, and the similarities will not be repeated here. Figures 2-4 As shown, the difference lies in the fact that the method also includes:

[0057] S11: After receiving the command sent by the operating handle, the control host monitors the status of the water supply pipeline, air supply pipeline and suction pipeline accordingly.

[0058] S12: Based on the feedback monitoring results, confirm whether the instructions have been accurately implemented;

[0059] This feedback mechanism allows for easy and accurate determination of whether a fault occurs at the operating handle or the control unit, enabling rapid troubleshooting. A specific implementation structure can be adopted as follows:

[0060] The integrated pipeline includes a sleeve 30, and a mounting bracket 34 is provided inside the sleeve 30 for installing a water supply pipeline 31, an air supply pipeline 32, and a suction pipeline 33. Each of the water supply pipeline 31, the air supply pipeline 32, and the suction pipeline 33 is provided with an arc-shaped flexible hose section 35 (preferably S-shaped). A monitoring unit is provided on the sleeve 30. The monitoring unit determines whether the pipeline is in working condition by monitoring whether the arc-shaped flexible hose section 35 vibrates.

[0061] Furthermore, the mounting bracket 34 includes multiple spaced positioning plates 340, each with three through holes for the water supply pipe 31, the air supply pipe 32, and the suction pipe 33 to pass through. The edges of the positioning plates 340 are fixedly connected to the inner wall of the sleeve 30. The monitoring unit includes a lamp body 36, a mounting rod 37, and three light sensors 38. Three arc-shaped flexible hose segments 35 are arranged around the lamp body 36, and the three light sensors 38 are distributed around the periphery of the three arc-shaped flexible hose segments 35. The mounting rod 37 is used to fix the lamp body 36 to two adjacent positioning plates 340. The lamp body 36 and the three light sensors 38 are all electrically connected to the control host via wires.

[0062] Initially, the light emitted by the lamp body 36 is blocked by three curved flexible tube segments 35, preventing the three light sensors 38 from detecting light. When any curved flexible tube segment 38 vibrates, the corresponding light sensor 38 will intermittently sense light (the curved flexible tube segment will intermittently leak light due to vibration). The control host determines whether the curved flexible tube segment is vibrating based on the electrical signal from the light sensor, and thus determines whether the pipeline is in working condition (if it is not in working condition, the curved flexible tube segment will not vibrate). Based on this, it is possible to accurately determine whether the fault occurs at the end of the operating handle or at the end of the control host, and at the same time, it is possible to effectively monitor faults in each pipeline.

The water supply unit 20, air supply unit 21, and suction unit 22 are respectively connected to the operating handle 1 through corresponding pipelines. The operating handle 1 is equipped with a sub-control board (not shown in the figure) and a button unit 10. The sub-control board is electrically connected to the main control board 23 and is used to send the control commands of the button unit 10 to the main control board 23. The main control board 23 controls the water supply unit 20, air supply unit 21, and suction unit 22 according to the commands.
