Description

Technical Field

[0001] This utility model belongs to the field of breathing tube technology, and in particular relates to a retractable, water-proof breathing tube for ventilators. Background Technology

[0002] A ventilator is a vital medical device that can prevent and treat respiratory failure, reduce complications, and save and prolong patients' lives, especially in intensive care units and clinical internal medicine settings. Ventilators are typically used in conjunction with humidifiers to reduce nasal irritation and improve comfort. During use, the humidifier fills the breathing tube with moisture, which is then delivered to the patient's airway along with oxygen. The breathing tube uses a corrugated tube to deliver oxygen; however, due to the complex internal structure of the corrugated tube, moisture can easily accumulate. With prolonged use, water will condense inside the breathing tube. If not cleaned promptly, the accumulated water may spray onto the face or nose, causing respiratory infections. Currently, condensate is collected using a condensate bottle. However, the condensate bottle on the ventilator can tip over due to changes in the patient's position, preventing it from remaining in a consistently low position. This prevents the water from draining easily, which can impair breathing, promote bacterial growth, and when the condensate bottle is removed from the breathing tube to empty the water, the tube's seal cannot be guaranteed, affecting oxygen delivery. Utility Model Content

[0003] The purpose of this invention is to provide a retractable, water-proof breathing tube for a ventilator, which can effectively collect water inside the breathing tube while ensuring the tube's airtightness and oxygen delivery effect.

[0004] The retractable, water-resistant breathing tube for the ventilator includes two corrugated breathing tubes and two connecting tubes. The two connecting tubes are located between the two corrugated breathing tubes. For each of the two connecting tubes, a fixing tube is installed inside the connecting tube. The fixing tube is rotatably connected to the connecting tube. A Y-shaped conduit is provided between the two connecting tubes. The two inlet ends of the conduit are connected to the two connecting tubes. The outlet end of the conduit is threadedly connected to a water collection bottle for collecting water accumulated in the corrugated breathing tube. A sealing component is provided on the outlet end of the conduit for unblocking or sealing the outlet end of the conduit.

[0005] Furthermore, the sealing assembly includes a sealing shell disposed inside the water outlet end of the conduit, a partition ring disposed inside the sealing shell to divide the sealing shell into two chambers, an inner and an outer chamber, a plurality of water inlet grooves connected to the outer chamber at the top of the sealing shell, a fixing hole connected to the inner chamber at the bottom of the sealing shell, a plurality of water outlet holes disposed on the partition ring, a sleeve disposed at the top of the sealing shell located in the inner chamber, a sliding rod inserted inside the sleeve, a sealing plug disposed at the bottom of the sliding rod to block the plurality of water outlet holes, a spring disposed between the sealing plug and the sealing shell, and a fixing rod disposed inside the fixing tube to push the piston to move.

[0006] Furthermore, a limiting tube is fitted onto the corrugated breathing tube, and a sliding groove is provided inside the limiting tube. Several sliders are provided in the sliding groove, and hooks are provided at the bottom of each slider.

[0020] Example 1

[0021] This embodiment describes a retractable, water-resistant breathing tube for a ventilator, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the device includes two corrugated breathing tubes 1 and two connecting tubes 4. The two connecting tubes 4 are located between the two corrugated breathing tubes 1. Corresponding to each of the two connecting tubes 4, a fixing tube 2 is provided on each of the two corrugated breathing tubes 1, which is inserted into the connecting tube 4. The fixing tube 2 is rotatably connected to the connecting tube 4. A Y-shaped conduit 5 is provided between the two connecting tubes 4. The two inlet ends of the conduit 5 are connected to the two connecting tubes 4. The outlet end of the conduit 5 is threadedly connected to a water collection bottle 7 for collecting water accumulated in the corrugated breathing tubes 1. The outlet end of the conduit 5 is provided with a device for discharging the water from the outlet end of the conduit 5. A sealing assembly for unblocking or sealing; two connecting pipes 4 are located between two corrugated breathing tubes 1, and each of the two corrugated breathing tubes 1 is equipped with a fixing pipe 2. The right end of the left corrugated breathing tube 1 is connected to the fixing pipe 2, and the left end of the right corrugated breathing tube 1 is connected to the fixing pipe 2. The corrugated breathing tube 1 and the fixing pipe 2 can be integrally molded, which facilitates production and makes the connection between the two more stable and sealed; the two fixing pipes 2 are respectively installed in the two connecting pipes 4, and the fixing pipes 2 are rotatably connected to the connecting pipes 4. The inner wall of the connecting pipe 4 is provided with a groove with an annular structure, and the groove limiting groove is provided with A limiting ring 3 is fixed to the outer wall of the fixing tube 2; the right end of the left fixing tube 2 passes through the left end of the left connecting tube 4, the limiting ring 3 is fixed to the outer wall of the right end of the left fixing tube 2, and the inner wall of the left end of the left connecting tube 4 has an annular groove, into which the limiting ring 3 of the left fixing tube 2 is embedded; the inner and outer sides of the right connecting tube 4 have grooves, and the outer wall of the left end of the right fixing tube 2 has a limiting ring 3 embedded in the groove, which rotates within the groove, allowing the two connecting tubes 4 to rotate freely on the two fixing tubes 2; a sealing ring is provided in the groove, and the connecting tube 4 While rotating, ensure the seal between the fixed pipe 2 and the connecting pipe 4 to prevent water from overflowing; the two connecting pipes 4 are connected by a Y-shaped conduit 5. The water inlet end on the left side of the conduit 5 is connected to the right end of the left connecting pipe 4, and the water inlet end on the right side of the conduit 5 is connected to the left end of the right connecting pipe 4. The outer wall of the water outlet end at the lower end of the conduit 5 is provided with external threads, and the bottle mouth of the water collection bottle 7 is provided with internal threads that are threaded to the external threads. The conduit 5 and the water collection bottle 7 are connected by the internal and external threads; and the connecting pipe 4 and the conduit 5 are integrally formed, which is convenient for production.

[0022] A sealing component is provided at the water outlet of the lower end of the conduit 5. The sealing component can be a one-way valve. The one-way valve is connected to the flange on the conduit 5. The one-way valve allows the water to flow through the water outlet of the conduit 5 to the water collection bottle 7, and the water is collected through the water collection bottle 7.

[0023] In use, the movable end of one corrugated breathing tube 1 is connected to a breathing mask, and the movable end of the other corrugated breathing tube 1 is connected to a ventilator. Oxygen generated by the ventilator is delivered to the breathing mask through the corrugated breathing tube 1, the fixing tube 2, the connecting tube 4, and the tubing 5 to provide oxygen to the patient. Oxygen supply via a ventilator is existing technology and will not be elaborated upon here. The water collection bottle 7, threaded to the lower end of the tubing 5, generates downward gravity. With the rotatable connection between the connecting tube 4 and the fixing tube 2, the water collection bottle 7 is positioned below the corrugated breathing tube 1. When water accumulates in the corrugated breathing tube 1, the fixing tube 2, the connecting tube 4, and the tubing 5, the corrugated breathing tube... Water accumulated in the corrugated breathing tube 1, fixed tube 2, and connecting tube 4 flows along the two inclined inlet ends of the tubing 5 to the outlet end on the lower side of the tubing 5. Opening the one-way valve allows the water to flow from the outlet end of the tubing 5 into the water collection bottle 7, which collects the water. When the water collection bottle 7 is full, the one-way valve is closed to seal the outlet end of the tubing 5, preventing water from dripping onto the ground and polluting the environment. The water in the water collection bottle 7 can be emptied and then reconnected to continue collecting water. Even after the water collection bottle 7 is removed from the tubing 5, it does not affect the oxygen delivery effect of the corrugated breathing tube 1, fixed tube 2, connecting tube 4, and tubing 5.

[0024] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a limiting tube 6 is fitted onto a corrugated breathing tube 1. A groove is formed inside the limiting tube 6, and several sliders 11 are installed within the groove. Each slider 11 has a hook 10 at its bottom. Several connecting rings 9 connected to the hooks 10 are provided on the corrugated breathing tube 1. Limiting tubes 6 are fitted onto both sections of the corrugated breathing tube 1. A groove is formed on the inner wall of the limiting tube 6, and several sliders 11 are installed within the groove. Hooks 10 are welded or glued to the bottom of each slider 11. Several connecting rings 9 are evenly distributed on the outer walls of both ends of the corrugated breathing tube 1. The corrugated breathing tube 1 is telescopic and bendable, allowing for arbitrary changes in the corrugated breathing pattern during use. The direction and length of tube 1 are suitable for use in different scenarios. Several hooks 10 inside the limiting tube 6 hook onto the connecting ring 9 on the corrugated breathing tube 1, so that the corrugated breathing tube 1 is compressed and its length is changed, or the connecting ring 9 can be removed from the hook 10 to lengthen the corrugated breathing tube 1. After the hook 10 hooks onto the connecting ring 9, the corrugated breathing tube 1 can be fixed inside the limiting tube 6, which improves the overall structural strength of the corrugated breathing tube 1 and prevents it from bending due to changes in the patient's body position, thus affecting its oxygen delivery effect. It can also prevent water from accumulating inside the corrugated breathing tube 1 and allow the accumulated water to flow better into the water collection bottle 7 for collection.

[0025] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the water collection bottle 7 is made of transparent material, either borosilicate glass or PP polypropylene. Borosilicate glass has high heat resistance and chemical stability, can completely withstand immersion in disinfectant and high-temperature and high-pressure sterilization, and can be reused. At the same time, its high transparency makes it easy to observe the amount of water in the water collection bottle 7 and to empty the water in time. PP polypropylene has good heat resistance and chemical stability, can meet the requirements of high-temperature and high-pressure sterilization, and also has high rigidity and fatigue resistance, is not easily broken, and has a high cost-performance ratio, which is conducive to recycling.

[0026] In actual use, the movable ends of the two corrugated breathing tubes 1 are connected to the ventilator and the breathing mask respectively to supply oxygen to the patient. The water collection bottle 7 is threaded to the water inlet of the tubing 5. With the rotating connection between the connecting tube 4 and the fixing tube 2, the water collection bottle 7 has weight, so the water collection bottle 7 is located on the lower side of the corrugated breathing tube 1. The water can flow along the two inclined water inlet ends of the tubing 5 to the water outlet end of the tubing 5. With the cooperation of the sealing component, the water enters the water collection bottle 7 and is collected to prevent the water from accumulating and breeding bacteria, which could cause respiratory infections. When the water collection bottle 7 is full, it is removed from the tubing 5. With the action of the sealing component, the water outlet end of the tubing 5 is sealed, which can prevent the water from dripping onto the ground and causing environmental pollution. The removal of the water collection bottle 7 does not affect the delivery of oxygen.

[0027] Example 2

[0028] This embodiment further illustrates the technology, such as Figure 1 , Figure 3 and Figure 5As shown, the sealing assembly includes a sealing shell 12 disposed inside the water outlet end of the conduit 5. The sealing shell 12 has a partition ring 13 that divides it into inner and outer chambers. The top of the sealing shell 12 has several water inlet grooves 15 communicating with the outer chamber, and the bottom of the sealing shell 12 has a fixing hole communicating with the inner chamber. The partition ring 13 has several water outlet holes 20. A sleeve 18 located in the inner chamber is disposed at the top of the sealing shell 12. A sliding rod 16 passes through the sleeve 18. A sealing plug 19 for sealing the water outlet holes 20 is disposed at the bottom of the sliding rod 16. A spring 14 is disposed between the sealing plug 19 and the sealing shell 12. A fixing rod 8 for pushing the piston is disposed inside the fixing tube 2. The sealing shell 12 is located inside the conduit 5. Inside the outlet end of the lower end of pipe 5, a sealing shell 12 is welded or adhered to the inner wall of the outlet end of pipe 5. A partition ring 13 is welded or adhered inside the sealing shell 12, dividing the interior of the sealing shell 12 into an outer chamber and an inner chamber. At least two water inlet grooves 15 are provided on the top of the sealing shell 12, communicating with the outer chamber. A fixing hole is provided on the bottom of the sealing shell 12, communicating with the water collection bottle 7. Several water outlet holes 20 are provided on the lower side of the partition ring 13. A sleeve 18 is welded or adhered to the top of the inner end of the sealing shell 12. A sliding rod 16 is installed inside the sleeve 18, sliding up and down with it. A sealing plug 19 is adhered to the bottom of the sliding rod 16. A spring 14 is provided between the sealing plug 19 and the top of the inner end of the sealing shell 12. One end of the spring 14 is welded to the top of the inner end of the sealing shell 12, and the other end... One end is attached to the top of the sealing plug 19. The spring 14 is fitted onto the outside of the slide rod 16 and the sleeve 18. A fixing rod 8 is welded or attached to the bottom of the water collection bottle 7. In use, the water collection bottle 7 is threaded to the outlet end of the conduit 5. As the mouth of the water collection bottle 7 gradually connects to the outlet end of the conduit 5, the fixing rod 8 inside the water collection bottle 7 passes through the fixing hole at the bottom of the sealing shell 12 and contacts the bottom of the sealing plug 19. The fixing rod 8 gradually pushes the sealing plug 19 upward. The upward movement of the sealing plug 19 causes the slide rod 16 to move upward within the sleeve 18. The spring 14 is compressed and deformed. The upward movement of the sealing plug 19 in the inner chamber can loosen the blockage of several water outlets 20, making the water outlets 20 unobstructed. Therefore, the water accumulated on the inner wall of the corrugated breathing tube 1, the fixing tube 2, the connecting tube 4, and the conduit 5 flows into the outlet end of the conduit 5. Inside, water flows into the outer cavity of the sealing shell 12 through several inlet channels 15. When the sealing plug 19 loosens its blockage on several outlet holes 20, the accumulated water flows into the inner cavity through several outlet holes 20, and then into the water collection bottle 7 through the fixing hole to collect the accumulated water. When the water collection bottle 7 is full, the water collection bottle 7 is removed from the outlet end of the conduit 5. The fixing rod 8 inside the water collection bottle 7 loosens its push on the sealing plug 19. Under the elastic force of the spring 14, the sealing plug 19 is pushed down, and the sliding rod 16 moves down in the sleeve 18. The sealing plug 19 seals the several outlet holes 20 again to ensure the sealing of the outlet end of the conduit 5 and prevent water from dripping and polluting the environment. Therefore, even if the water collection bottle 7 is removed from the conduit 5, it will not affect the oxygen delivery.

[0029] like Figure 1 , Figure 3 and Figure 5 As shown, the inner wall of the sleeve 18 has two symmetrically distributed limiting grooves, each of which is provided with a limiting block 17 that slides and is fixed to the slide rod 16; the inner wall of the sleeve 18 has two limiting grooves, each of which is provided with a limiting block 17 that slides up and down with it. The limiting blocks 17 are welded or glued to the side wall of the slide rod 16. The sliding cooperation between the limiting grooves and the limiting blocks 17 makes the slide rod 16 move up and down more smoothly and steadily in the sleeve 18, and also prevents the slide rod 16 from falling out of the sleeve 18, ensuring the stability of the connection between the slide rod 16 and the sleeve 18, and better driving the sealing plug 19 to unclog or block the water outlet 20, ensuring the sealing of the water outlet end of the conduit 5;

[0030] like Figure 1 , Figure 3 and Figure 5 As shown, the fixing rod 8 is made of stainless steel. Stainless steel has excellent corrosion resistance and is not easy to rust, ensuring the stability and service life of the fixing rod 8. The surface of stainless steel is smooth, not easy to accumulate dirt, and easy to clean, which helps to keep the fixing rod 8 clean and hygienic. Stainless steel has a large weight, which puts the water bottle 7 under the corrugated breathing tube 1, ensuring that the water flows smoothly into the water bottle 7.
