Description

Technical Field

[0001] This invention relates to the field of non-invasive ventilator technology, and more specifically, to a non-invasive ventilator tubing storage and disinfection device for life support systems. Background Technology

[0002] In modern clinical medicine, non-invasive ventilators, as one of the core devices of the life support system, are widely used in the treatment and assisted breathing of patients with respiratory failure, sleep apnea syndrome, etc. They are connected to the patient's airway through a mask, eliminating the need for tracheal intubation or endotracheal intubation, effectively reducing the risk of infection and improving patient comfort. Therefore, they play an irreplaceable role in ICU, respiratory wards and home care. However, the tubing of non-invasive ventilators, as a key component connecting the device and the patient, has long been a source of concern for medical professionals in terms of its daily storage, cleaning, and disinfection. Currently, in clinical practice, ventilator tubing is mostly stored manually after being wrapped and placed haphazardly, lacking specialized storage equipment. Since the tubing is typically 1.5-2 meters long and is mostly made of flexible plastic, manual storage easily leads to tangling and knotting, which not only occupies a lot of storage space but also increases the time required for organization the next time it is used, affecting the efficiency of medical staff. At the same time, the messy stacking of tubing is susceptible to external contamination, increasing the risk of infection for patients. In the disinfection process, existing disinfection methods mostly target the surface of the pipes. When cleaning the inside of the pipes, they are mostly soaked in diluted disinfectant. However, it is difficult to clean the thick phlegm inside the pipes, which makes it easy for bacteria, mold and other microorganisms to grow inside the pipes and form biofilms. These contaminants can enter the patient's body through breathing and may cause serious complications such as ventilator-associated pneumonia, affecting the patient's treatment effectiveness.

[0023] Example 1 further illustrates the non-invasive ventilator tubing storage and disinfection device for life support systems proposed in this invention.

[0024] A non-invasive ventilator tubing storage and disinfection device for life support systems includes a storage box 1 with an open top and a cover plate 2 covering the top of the storage box 1. It also includes a tubing storage mechanism rotatably connected to the inner wall of the storage box 1 and is used to retract the tubing on the non-invasive ventilator.

[0025] The disinfection box 3 is fixedly connected to the outer wall of the storage box 1. The disinfection box 3 is used to dilute disinfectants. The disinfection box 3 is connected to the pipe storage mechanism through the connecting pipe 4. The top of the disinfection box 3 has an inlet, through which disinfectants such as sodium hypochlorite solution and hydrogen peroxide solution can be injected into the disinfection box 3 and diluted with a certain proportion of purified water, so as to facilitate the dilution and loading of disinfectants for later use.

[0026] The drive mechanism is located on the top of the disinfection box 3 and is used to drive the pipe storage mechanism to rotate.

[0027] The cleaning mechanism is located inside the storage box 1 and works in conjunction with the tubing storage mechanism. The cleaning mechanism is used to clean the inside of the ventilator tubing.

[0028] The cleaning mechanism includes a control box 5, a rotating plate 6 rotatably connected to the outer wall of the control box 5, and bristles 7 fixedly connected to the outer ring wall of the rotating plate 6. The bristles 7 are used to clean the inner wall of the pipeline. A second drive motor 42 is fixedly connected to the side wall of the control box 5. The output shaft of the second drive motor 42 passes through the side wall of the receiving cavity and is fixedly connected to the rotating plate 6 to drive the rotating plate 6 to rotate. The control box 5 is equipped with a storage device such as a battery in the prior art. The wires on the second drive motor 42 are electrically connected to the storage device. The second drive motor 42 is a medical micro motor, which makes it easy to fix the second drive motor 42 in the control box 5.

[0029] The scraper 8 is fixedly connected to the side wall of the control box 5 away from the rotating plate 6. The scraper 8 is used to scrape off the residue on the inner wall of the tubing. The scraper 8 is annular, and the end of the scraper 8 can fit against the inner wall of the ventilator tubing, so that the scraper 8 can scrape off the residue on the inner wall of the ventilator tubing.

[0030] The control component is located on the inner wall of the storage box 1 and is used to control the movement of the control box 5.

[0031] The pipe storage mechanism includes a rotating rod 9, the end of which is rotatably connected to the inner side wall of the storage box 1, and the end of the rotating rod 9 passes through the side wall of the storage box 1 and extends to its outside.

[0032] Baffle 10 is symmetrically arranged on the rotating rod 9, and the center of baffle 10 is fixedly connected to the rotating rod 9.

[0033] The partition 11 is fixedly connected to the rotating rod 9 and is located between the two baffles 10. The partition 11 divides the space between the two baffles 10 into a first winding chamber 12 and a second winding chamber 13. The first winding chamber 12 is close to the disinfection box 3 and the width of the first winding chamber 12 is equal to the diameter of the outer ring wall of the ventilator tubing. When the ventilator tubing is wound on the rotating rod 9 located in the first winding chamber 12, it is convenient for the ventilator tubing to be wound in a planar spiral shape on the rotating rod 9.

[0034] The interior of the rotating rod 9 is hollow. The lower end of the connecting pipe 4 is rotatably connected to the side wall of the rotating rod 9 and communicates with the rotating rod 9. The upper end of the connecting pipe 4 is fixedly connected to the bottom of the disinfection box 3 and communicates with the disinfection box 3.

[0035] A connecting ring 14 is fixedly connected to the top of the rotating rod 9. The bottom of the connecting ring 14 is connected to the inside of the rotating rod 9. The connecting ring 14 is used to fix the end of the tube to the rotating rod 9. The connecting ring 14 is located in the first winding chamber 12. The tube is removed from the ventilator by existing technology, and the end of the tube is fixed to the connecting ring 14 by existing technology, such as inserting the end of the tube into the connecting ring 14 or binding it to the connecting ring 14 with a strap. The tube is connected to the inside of the rotating rod 9 through the connecting ring 14, which facilitates the rotating rod 9 to wind up the tube. At the same time, it is convenient for the diluted disinfectant in the disinfection box 3 to enter the inside of the tube through the rotating rod 9, thereby achieving flushing of the inside of the tube and ensuring the cleanliness of the inside of the tube.

[0036] An arc-shaped protective plate 15 is fixedly connected to the rotating rod 9. The connecting ring 14 is located at the open end of the arc-shaped protective plate 15. The distance between the inner and outer arc walls of the arc-shaped protective plate 15 is equal to the height of the connecting ring 14. The end of the arc-shaped protective plate 15 is arc-shaped, which facilitates the winding of the pipeline onto the arc-shaped protective plate 15. At the same time, since the height of the arc-shaped protective plate 15 is consistent with the height of the connecting ring 14, and the connecting ring 14 is located inside the opening of the arc-shaped protective plate 15, that is, between the two ends of the arc-shaped protective plate 15, when the pipeline is wound onto the arc-shaped protective plate 15, the squeezing force of the pipeline wound on the outer ring between the pipeline and the connecting ring 14 can be reduced, thereby preventing damage to the connection between the pipeline and the connecting ring 14.

[0037] A limiting mechanism is slidably connected to the inner wall of the storage box 1. The limiting mechanism is used to control the movement of the tubing. The limiting mechanism includes an arc-shaped plate 16. The diameter of the inner arc wall of the arc-shaped plate 16 is equal to the diameter of the outer ring wall of the ventilator tubing. A telescopic plate 17 is fixedly connected to the outer arc wall of the arc-shaped plate 16. The end of the telescopic plate 17 is slidably connected to the inner wall of the storage box 1. The arc-shaped plate 16 matches the partition 11. At least two arc-shaped notches 20 are opened on the circumferential wall of the partition 11. The arc-shaped notches 20 cooperate with the arc-shaped plate 16. The diameter of the arc wall is equal to the diameter of the outer ring wall of the pipeline. A sliding block is fixedly connected to one end of the telescopic plate 17 away from the arc plate 16. A horizontal strip groove is opened on the inner side of the storage box 1. The sliding block is slidably connected in the strip groove. A first spring is provided in the telescopic plate 17. One end of the first spring is fixedly connected to the outer arc wall of the arc plate 16, and the other end of the first spring is fixedly connected to the sliding block. The natural state of the first spring is in an extended state. When the first spring is in its natural state, the telescopic plate 17 is fully extended.

[0038] An electric telescopic rod 18 is fixedly connected to the inner wall of the storage box 1. The electric telescopic rod 18 is fixed to a rectangular frame 19, which is sleeved on the telescopic plate 17. The electric telescopic rod 18 pushes the telescopic plate 17 back and forth through the rectangular frame 19, thereby controlling the arc plate 16 to move back and forth, so as to facilitate pushing the pipeline towards the second winding chamber 13 through the arc plate 16.

[0039] The drive mechanism includes a first drive motor 21, which is fixedly connected to the top of the disinfection box 3. The wires on the first drive motor 21 are electrically connected to existing energy storage devices such as batteries to facilitate the normal operation of the first drive motor 21.

[0040] The lower end of the drive shaft 22 is rotatably connected to the bottom of the disinfection box 3, and the output shaft of the first drive motor 21 passes through the top of the disinfection box 3 and is fixedly connected to the upper end of the drive shaft 22.

[0041] The upper end of the worm gear 23 is fixedly connected to the lower end face of the drive shaft 22.

[0042] The turbine 24 is fixedly connected to the end of the rotating rod 9. The turbine 24 meshes with the worm 23. When the output shaft of the first drive motor 21 drives the worm 23 to rotate through the drive shaft 22, the worm 23 meshes with the turbine 24, thereby driving the rotating rod 9 to rotate through the turbine 24. During the rotation, the rotating rod 9 winds up the pipeline.

[0043] The bottom of the disinfection box 3 is rotatably connected to a driven shaft 25 symmetrically arranged about the drive shaft 22. The upper end of the drive shaft 22 is fixedly connected to a drive gear 26, and the upper end of the driven shaft 25 is fixedly connected to a driven gear 27. The driven gear 27 meshes with the drive gear 26.

[0044] At least two stirring rods 28 are fixedly connected to the circumferential walls of the drive shaft 22 and the driven shaft 25, and the stirring rods 28 on the drive shaft 22 and the stirring rods 28 on the driven shaft 25 cooperate with each other. The stirring rods 28 are used to stir the disinfectant and purified water in the disinfection box 3, so as to facilitate the mixing of the disinfectant and purified water.

[0045] The control assembly includes a control ring 29 located below the rotating rod 9. A connecting rod 30 is fixedly connected to the bottom of the control ring 29. The connecting rod 30 is slidably connected to the inner wall of the storage box 1. A groove is provided at the bottom of the storage box 1, and a slider is slidably connected in the groove. A limit rod is fixedly connected to the upper surface of the slider. A circular through hole is provided on the connecting rod 30, and the connecting rod 30 is sleeved on the limit rod through the circular through hole and can slide on the limit rod. A second spring is fixedly connected to the upper surface of the slider, and the upper end of the second spring is fixedly connected to the lower surface of the connecting rod 30, so that the connecting rod 30 can slide up and down on the limit rod, thereby facilitating the up and down movement of the control ring 29. The natural state of the second spring is fully extended. When the connecting rod 30 drives the control ring 29 to slide downward, the second spring gradually contracts.

[0046] The lower end of the connecting plate 31 is engaged with the connecting rod 30, and the upper end of the connecting plate 31 is fixedly connected to the lower surface of the rectangular frame 19. The lower end of the connecting plate 31 is fixedly connected to the slider at the bottom of the storage box 1. When the electric telescopic rod 18 pushes the rectangular frame 19 to one side, the connecting plate 31 pushes the slider to one side, thereby driving the control ring 29 to move to one side.

[0047] A metal ring 32 is fixedly connected to the outer ring wall of the control box 5. The control ring 29 is made of permanent magnet material, and the control ring 29 cooperates with the metal ring 32. The magnetic force of the control ring 29 attracts the metal ring 32, thereby preventing the metal ring 32 from getting stuck in the pipeline, thus facilitating the movement of the control box 5 in the pipeline. The diameter of the outer ring wall of the metal ring 32 is less than or equal to the diameter of the inner ring wall of the pipeline, making it easy to place the control box 5 in the pipeline, thus facilitating the cleaning of the inside of the pipeline.

[0048] A fixing block 33 is fixedly connected to the inner wall of the storage box 1. A U-shaped plate 34 is fixedly connected to the upper surface of the fixing block 33. An ultraviolet sterilization lamp 35 is fixedly connected to the inner wall of the U-shaped plate 34. The ultraviolet sterilization lamp 35 facilitates the sterilization of the inside of the mask at the end of the pipeline. The ultraviolet sterilization lamp 35 is connected to the central processing unit in the background via a signal. The central processing unit in the background controls the opening time and sterilization duration of the ultraviolet sterilization lamp 35.

[0049] A positioning block 36 is fixedly connected to the outer wall of the U-shaped plate 34. At least two positioning grooves 37 are provided on the side wall of the positioning block 36 away from the U-shaped plate 34. The positioning grooves 37 are used to fix the straps on the mask, so as to make it easier to tie the straps on the mask to the positioning block 36 and prevent the mask from sliding down.

[0050] A nozzle 38 is fixedly connected to the top of the U-shaped plate 34. A delivery pipe 39 is fixedly connected to one end of the nozzle 38. One end of the delivery pipe 39 is rotatably connected to the rotating rod 9 and communicates with the rotating rod 9. The delivery pipe 39 is a telescopic hose, which allows the disinfectant diluted in the rotating rod 9 to enter the nozzle 38 through the delivery pipe 39 and be sprayed onto the face mask through the nozzle 38, thereby achieving the cleaning and disinfection of the face mask at the end of the pipeline. An automatic control valve is installed in the nozzle 38 to control the opening and closing of the nozzle 38.

[0051] The storage box 1 has a water tank 40 at the bottom and a drain hole 41 at the bottom of the water tank 40. The water tank 40 is used to collect the diluted disinfectant dripping from the mask and drain it through the drain hole 41, thereby preventing the disinfectant from accumulating at the bottom of the storage box 1 after cleaning. The drain hole 41 is connected to the waste disinfectant collection bucket or waste disinfectant collection box specified in the prior art through a connecting pipe, which facilitates the collection and treatment of the waste disinfectant after use and avoids the waste disinfectant from causing pollution to the environment.

[0052] Working principle: Before using the device, necessary preliminary preparations are required. Disinfectants such as sodium hypochlorite solution and hydrogen peroxide solution are injected into the disinfection tank 3 through the feed inlet at the top of the disinfection tank 3. At the same time, purified water is added in a certain proportion. Then, the first drive motor 21 in the drive mechanism starts, and its output shaft drives the worm gear 23 to rotate through the drive shaft 22. Since the worm gear 23 meshes with the drive gear 26 on the driven shaft 25, it will drive the driven shaft 25 to rotate. The stirring rod 28 on the drive shaft 22 and the driven shaft 25 will rotate accordingly, which will fully stir the disinfectant and purified water in the disinfection tank 3, so that the two are mixed together, and the disinfectant is diluted and ready for use, in preparation for subsequent disinfection work. Turn off the first drive motor 21, remove the tubing from the non-invasive ventilator, and then insert the control box 5 into the tubing, so that the brush 7 is opposite to the end of the tubing, that is, the brush 7 is close to the connection part between the tubing and the connecting ring 14. Then, pass the end of the tubing through the control ring 29 and fix it to the connecting ring 14 on the rotating rod 9 by means of existing technology such as insertion or binding with straps, to ensure that the tubing is connected to the inside of the rotating rod 9 through the connecting ring 14. Since the control ring 29 is made of permanent magnet material, when the end of the tubing passes through the control ring 29, the attraction of the metal ring 32 by the magnetism of the control ring 29 causes the metal ring 32 to move the control box 5 to stay inside the control ring 29.

[0053] The drive mechanism is restarted, and the first drive motor 21 continues to work. Its output shaft drives the worm 23 to rotate via the drive shaft 22. The worm 23 meshes with the turbine 24 fixed to the end of the rotating rod 9, thereby driving the rotating rod 9 to rotate. Since the number of worm heads on the worm 23 is less than the number of meshing teeth on the turbine 24, the number of worm heads on the worm 23 after one rotation determines the number of meshing teeth on the turbine 24 that rotate. For example, if the worm 23 has 4 worm heads, then after one rotation, the worm 23 drives 4 meshing teeth on the turbine 24 to rotate. Therefore, the speed of the worm 23 is greater than the speed of the turbine 24, thereby driving the first drive motor 21 to rotate through the meshing of the drive gear 26 and driven gear 27 on the drive shaft 22, driving the driven shaft 25 and the stirring rod 28 to rotate. 28. The disinfectant and purified water in the disinfection box 3 are stirred at high speed to promote the mutual mixing of disinfectant and purified water. Since the speed of turbine 24 is less than that of worm gear 23, when worm gear 23 meshes and drives turbine 24 to rotate, turbine 24 drives rotating rod 9 to rotate slowly, so that rotating rod 9 slowly winds up the tubing. During the slow winding of the tubing, when the inner wall of the tubing passes the control box 5, scraper 8 pushes the residue on the inner wall of the tubing away from the connecting ring 14, thereby cleaning the residue on the inner wall of the tubing. At the same time, when rotating rod 9 rotates, the first winding chamber 12, located between the two baffles 10 and separated by partition 11, begins to wind up the tubing. Since the width of the first winding chamber 12 is equal to the diameter of the outer ring wall of the ventilator tubing, the tubing will be wound in a planar spiral shape on rotating rod 9.

[0054] The connecting ring 14 is equipped with an automatic control valve, which controls the intermittent opening and closing of the connecting ring 14. When the automatic control valve in the connecting ring 14 is opened, the diluted disinfectant in the disinfection box 3 enters the pipeline through the connecting ring 14, thereby flushing the pipeline. When the disinfectant comes into contact with the control box 5, the second drive motor 42 is turned on. The output shaft of the second drive motor 42 drives the rotating plate 6 and the brush 7 to rotate, thereby causing the brush 7 to scrub the inner wall of the pipeline, further cleaning the residue on the inner wall of the pipeline, and ensuring that the inner wall of the pipeline is clean and tidy. During the pipe winding process, when the outermost end of the spiral plane of the pipe contacts the arc plate 16, as the pipe continues to wind up and the diameter of the spiral plane gradually increases, the wound pipe pushes the arc plate 16 away from the rotating rod 9. At this time, the first spring inside the telescopic plate 17 gradually contracts. Simultaneously, as the pipe winds up, the area of ​​the spiral plane formed by the winding increases, causing the pipe located at the outer end of the winding plane to push the control ring 29 downward. Meanwhile, the second spring below the connecting rod 30 gradually contracts. When the upper end of the control ring 29 is flush with the lower end of the baffle 10, the open end of the arc plate 16 is flush with the end of the circumferential wall of the partition 11. At this time, the electric telescopic rod 18 is activated, and the electric telescopic rod 18 passes through the rectangular frame 19. The telescopic plate 17 is pushed to move, which in turn drives the arc plate 16 and the connecting rod 30 to move the control ring 29 toward the second winding chamber 13. At the same time, the magnetic attraction on the control ring 29 drives the metal ring 32 and the control box 5 to move toward the second winding chamber 13. When the arc plate 16 drives the pipeline toward the second winding chamber 13, the rotating rod 9 drives the partition 11 and the baffle 10 to rotate. During the rotation of the partition 11, when the position of the arc notch 20 corresponds to the position of the pipeline, the arc plate 16 pushes the pipeline into the second winding chamber 13 through the arc notch 20. At the same time, during the rotation of the partition 11, due to the restriction of the pipeline by the arc notch 20, it is easy for the pipeline to be wound around the rotating rod 9 in the position inside the second winding chamber 13.

[0055] When the control ring 29 enters the second winding chamber 13, the control ring 29 is released from the downward pushing force of the pipeline. Through the elastic force generated by the extension of the second spring, the second spring pushes the connecting rod 30 upward, causing the connecting rod 30 to drive the control ring 29 to move upward. This brings the control ring 29 closer to the rotating rod 9, making it easier for the pipeline to wind around the part of the rotating rod 9 located in the second winding chamber 13. This facilitates the orderly winding of the auxiliary pipeline on the rotating rod 9 and avoids the pipeline from piling up messily during the winding process. Disinfection is carried out simultaneously with pipe storage and cleaning. The diluted disinfectant in the disinfection box 3 enters the rotating rod 9 intermittently through the connecting pipe 4. Since the pipe is wound in a planar spiral shape on the rotating rod 9, when the rotating rod 9 drives the pipe to rotate to its lower side during the winding process, the disinfectant flows downward due to gravity, thus causing the disinfectant in the pipe to spiral out of the pipe in a planar spiral shape. This achieves disinfection treatment by injecting small amounts of disinfectant multiple times during management.

[0056] In addition, by opening the cover plate 2 and removing the mask from the end of the pipeline using existing technology, the mask is secured to the positioning block 36 with the straps on the mask, and the straps are positioned in the positioning groove 37. The protrusion on the lower side of the positioning groove 37 prevents the straps from sliding downwards with the mask, thus facilitating the fixation of the mask. The inside of the mask is opposite to the ultraviolet sterilization lamp 35. The automatic control valve in the nozzle 38 is turned on, and the disinfectant in the disinfection box 3 enters the nozzle 38 through the connecting pipe 4, rotating rod 9, and conveying pipe 39, and is sprayed onto the inner wall of the mask, thus rinsing the mask. After rinsing the mask, the ultraviolet sterilization lamp 35 is turned on to sterilize the inside of the mask, thus further sterilizing the inside of the mask. Waste liquid generated during the cleaning and disinfection process drips through the mask into the water tank 40 at the bottom of the storage box 1, and is finally discharged through the drain hole 41 at the bottom of the water tank 40. It then enters the designated waste disinfectant collection bucket or collection box through the connecting pipe to complete the collection and treatment of waste liquid. Through the cooperation of the rotating rod 9, baffle 10 and partition 11 of the tubing storage mechanism, and the auxiliary push of the limiting mechanism, the ventilator tubing can be orderly wound into the first winding chamber 12 and the second winding chamber 13 in a planar spiral shape, avoiding the tubing from being messy and tangled, saving storage space, and facilitating the storage and management of the tubing. The disinfection box 3 can accurately dilute the disinfectant and deliver the diluted disinfectant to the inside of the tubing through the connecting pipe 4, achieving comprehensive flushing and disinfection of the inside of the tubing. At the same time, the ultraviolet sterilization lamp 35 sterilizes the inside of the mask, and the nozzle 38 cleans and disinfects the mask. The multi-dimensional disinfection method ensures the disinfection effect of the tubing and mask, effectively killing bacteria, viruses and other microorganisms, ensuring the hygiene and safety of the ventilator tubing, and reducing the risk of cross-infection for patients. The rotating plate 6 in the cleaning mechanism drives the brush bristles 7 to rotate, which can clean the inner wall of the pipe in all directions. The scraper 8 can effectively scrape off the residue on the inner wall of the pipe. The two work together to thoroughly remove dirt and impurities inside the pipe, ensuring the cleanliness of the pipe and preventing bacteria from growing in the residue, which would affect the performance. The drive mechanism is driven by a motor, which realizes the automation of processes such as pipeline storage and disinfectant mixing, reducing the intensity of manual operation. The control component controls the movement of the cleaning mechanism in the pipeline through magnetic attraction, making the operation flexible and convenient. All mechanisms of the entire device work together to complete the storage, cleaning and disinfection process in one integrated manner, improving work efficiency and saving manpower and time costs. The device is equipped with a water storage tank 40 and a drain hole 41 to centrally collect and treat used disinfectant, avoiding indiscriminate discharge of waste disinfectant and causing environmental pollution, thus meeting environmental protection requirements. Meanwhile, the design of each mechanism is reasonable; for example, the arc-shaped protective plate 15 reduces the pressure on the connection points when the pipeline is wound, preventing pipeline damage, extending the service life of the pipeline, and ensuring the safety of the device during use.
