[0001] This utility model relates to the field of pipeline flushing technology, specifically to a resettable negative pressure pipeline flushing device. Background Technology

[0002] In healthcare settings, flushing and disinfection of tubing are crucial steps in ensuring the hygiene and safety of medical equipment, instruments, and related systems, and preventing cross-infection. Especially during the use of medical devices such as gastric tubes, urinary catheters, intravenous infusion lines, and ventilator tubing, the presence of residual liquids or contaminants can easily breed bacteria, leading to nosocomial infections and posing a serious threat to patient health. Therefore, regularly and thoroughly cleaning and disinfecting these tubing is a key aspect of ensuring medical quality and patient safety.

[0003] Traditional flushing methods typically rely on manual operation, such as repeatedly aspirating with a syringe or using gravity dripping to deliver flushing fluid into the tubing for cleaning. In addition, some medical institutions employ more complex mechanical devices, such as electric pumps or pneumatic flushing equipment, to automate or semi-automate the flushing process. However, these traditional methods generally suffer from cumbersome operation and complex procedures, requiring highly skilled medical personnel and being prone to incomplete flushing or operational errors due to human factors.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] According to an embodiment of the present invention, a resettable negative pressure pipeline flushing device is provided.

[0027] Example 1

[0028] like Figures 1-4As shown, the resettable negative pressure pipeline flushing device according to an embodiment of the present invention includes an installation cylinder 1, which is the basic component of the entire device. Its internal space is used to accommodate the piston 4 and other related components. One side of the installation cylinder 1 is connected to an inlet pipe 2, which is responsible for introducing the flushing liquid to be extracted into the installation cylinder 1. The other side is connected to an outlet pipe 3, which is used to discharge the flushing liquid to the target location. The piston 4 is provided inside the installation cylinder 1. The function of the piston 4 is to change the pressure inside the installation cylinder 1 by moving when the button 7 is pressed, thereby realizing the suction or discharge of liquid. The piston 4 is connected to the mounting plate 5 on one side, and the mounting plate 5 is connected to the moving rod 6. The moving rod 6 is the key part of the force transmission in the whole device. Through it, the pressure applied by the user to the button 7 can be accurately transmitted to the piston 4, causing the piston 4 to move inside the mounting cylinder 1. The moving rod 6 is connected to the button 7, and a telescopic spring 8 is provided on the outside of the moving rod 6. One end of the telescopic spring 8 is connected to the mounting plate 5, and the other end is connected to the mounting ring 9. When the button 7 is released, the telescopic spring 8 will automatically return to its original state, pushing the mounting plate 5 and the piston 4 back to their original positions, realizing the function of automatic reset. The mounting ring 9 is connected to the mounting cylinder 1, and the moving rod 6 passes through the middle of the mounting ring 8. The mounting ring 9 is mainly used to fix one end of the telescopic spring 8. Limiting plates 10 are provided on both sides of the moving rod 6, and limiting grooves 11 are provided on the mounting ring 9. The limiting plates 10 and the limiting grooves 11 match to ensure that the moving rod 6 will not deviate when subjected to force and always maintain the correct movement trajectory, thereby enhancing the stability and reliability of the system.

[0029] like Figures 1-4As shown, the outlet pipe 3 is equipped with a first one-way valve 12 to ensure that the liquid can only flow from the inside of the mounting cylinder 1 to the flushing pipe 14 and cannot flow in the reverse direction. This prevents the discharged liquid from flowing back into the mounting cylinder 1, ensuring the cleanliness of the flushing process. One end of the outlet pipe 3 is connected to the first connecting connector 13, which is connected to the flushing pipe 14. The inlet pipe 2 is equipped with a second one-way valve 15, which ensures that the liquid can only be drawn from the storage bottle 19 into the mounting cylinder 1, preventing the liquid from flowing back into the storage bottle 19. This helps maintain a negative pressure state in the system and improves the extraction efficiency. One end of the inlet pipe 2 is connected to the second connecting connector 16, which is connected to the extraction pipe 17. The extraction pipe 17 is responsible for drawing the flushing liquid from the storage bottle 19 into the mounting cylinder 1. Its length and flexibility are determined according to the position of the storage bottle 19 and the requirements of the operating environment, so as to facilitate flexible use by the operator. The extraction tube 17 is connected to the bottle cap 18, and the bottle cap 18 is threadedly connected to the bottle mouth of the storage bottle 19. The storage bottle 19 is used to store the rinsing fluid to be used. A vent hole 20 is provided on one side of the top of the storage bottle 19 to allow air to enter to balance the internal and external pressure, which is conducive to the smooth extraction of liquid and can prevent the storage bottle 19 from deforming during the extraction process. A fixing ring 21 is fitted on the outside of the bottle mouth of the storage bottle 19. A sealing plug 23 is connected to the outside of the fixing ring 21 through a connecting rope 22. The sealing plug 23 matches the vent hole 20. Normally, it blocks the vent hole 20 to prevent liquid evaporation or external contaminants from entering the storage bottle 19. When it is necessary to balance the air pressure, the sealing plug 23 is removed to allow air to enter the storage bottle 19 through the vent hole 20.

[0030] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0031] In summary, with the help of the above-mentioned technical solution of this utility model, in actual use, the user first connects the flushing tube 14 to the pipe to be cleaned, while ensuring that the extraction tube 17 is inserted into the storage bottle 19, and removes the sealing plug 23 from the vent 20 to maintain the air pressure balance inside and outside the storage bottle 19. At this time, the device is in its initial state. The piston 4 is located inside the mounting cylinder 1 near the button 7. The telescopic spring 8 is in its naturally extended state. When the button 7 is pressed manually, the pressing force is transmitted to the mounting plate 5 through the moving rod 6, which in turn drives the piston 4 to push into the mounting cylinder 1, compressing the space at the front end (liquid outlet side) of the mounting cylinder 1. Under the action of the first one-way valve 12 and the second one-way valve 15, the air or rinsing liquid inside the mounting cylinder 1 can be discharged through the liquid outlet pipe 3. When released, it resets under the action of the spring 8, increasing the volume of the front end of the piston 4 inside the mounting cylinder 1 and generating negative pressure. Under the action of the second one-way valve 15, the disinfectant in the storage bottle 19 can be sucked into the mounting cylinder 1. At this time, the first one-way valve 12 is in the closed state to prevent air or liquid in the liquid outlet pipe 3 from being sucked back into the mounting cylinder 1, maintaining a negative pressure state. After rinsing is completed, the sealing plug 23 can be inserted into the vent 20 to prevent liquid evaporation or external pollutants from entering the storage bottle 19.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
