Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a high-frequency and high-flow humidifier connecting tube. Background Art

[0002] Oxygen humidification is a common technique used clinically. It uses a humidifier bottle to moisten the airway while the patient is receiving oxygen. This keeps the patient's trachea moist, allowing for increased oxygen intake to reduce blood oxygen saturation and prevent cerebral hypoxia. Maintaining a moist trachea also prevents the formation of phlegm crusts, reducing the number of suctioning procedures, and reducing both the workload of medical staff and the risk of injury to the patient.

[0003] According to the oxygen humidification water filtration connecting tube with application number 202320497577.2, water will gradually accumulate inside the air inlet and outlet cavities during prolonged use. However, because the outlet pipe inside the outlet cavity is higher than the bottom of the outlet cavity, the accumulated water is unlikely to enter the outlet channel. When excessive water accumulates, the air inlet and outlet parts can be separated from the filter part to drain the accumulated water.

[0004] However, the above-mentioned connecting tube has certain shortcomings. The accumulated water in the connecting tube can only be contained at the bottom of the air outlet cavity when the connecting tube is in a vertical state. If the air outlet cavity is tilted and shaken, the accumulated water will still enter the air outlet connecting tube and be inhaled by the patient, which will then cause the patient to choke on water. Therefore, there are certain shortcomings. For this reason, we propose a high-frequency and high-flow humidifier connecting tube. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present invention provides a high-frequency and high-flow humidifier connecting tube, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a high-frequency and high-flow humidifier connecting pipe, including a filter cartridge and an air inlet hood, an air inlet pipe is installed inside the top of the air inlet hood, a threaded sleeve is movably sleeved on the outer side of the air inlet pipe, the threaded sleeve is threadedly connected to the filter cartridge, an air outlet pipe is installed inside the bottom of the filter cartridge, absorbent cotton is provided at the bottom of the filter cartridge, a drain pipe is fixedly installed inside the bottom of both sides of the filter cartridge, a connecting cover is fixedly installed at one end of the drain pipe, a collecting bottle is threadedly installed on the internal thread of the connecting cover, a cotton strip is provided inside the drain pipe, one end of the cotton strip extends to the interior of the collecting bottle, and a dripper is provided at one end of the cotton strip.

[0012] The utility model provides a high-frequency and high-flow humidifier connecting tube, which has the following beneficial effects:

[0013] 1. The high-frequency and high-flow humidifier connecting pipe is equipped with absorbent cotton, drain pipe, connecting cover, collection bottle, cotton strips and drippers. When filtered water accumulates in the filter cartridge, the absorbent cotton can absorb the accumulated water, and the cotton strips and drippers will use the capillary effect to guide the accumulated water through the drain pipe into the collection bottle for collection. This can effectively avoid residual water in the filter cartridge and prevent the accumulated water from entering the exhaust pipe and causing the patient to choke on water, which is safer.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] See also Figures 1 to 5 The utility model provides a technical solution: a high-frequency and high-flow humidifier connecting pipe, including a filter cartridge 1 and an air intake cover 2. An air intake pipe 3 is installed inside the top of the air intake cover 2. A threaded sleeve 4 is movably sleeved on the outside of the air intake pipe 3. The threaded sleeve 4 is threadedly connected to the filter cartridge 1. A threaded sleeve 4 is provided on the outside of the filter cartridge 1 to cooperate with the threaded sleeve 4. An air outlet pipe 5 is installed inside the bottom of the filter cartridge 1. Water-absorbing cotton 6 is provided at the bottom of the interior of the filter cartridge 1. Drain pipes 7 are fixedly installed inside the bottom of both sides of the filter cartridge 1. A connecting cover 8 is fixedly installed at one end of the drain pipe 7. A collecting bottle 9 is threadedly installed on the internal thread of the connecting cover 8. A cotton sliver 10 is provided inside the drain pipe 7. One end of the cotton sliver 10 extends to the interior of the collecting bottle 9, and a dripper 11 is provided at one end of the cotton sliver 10.

[0022] A filter element 12 is provided at the top of the filter cartridge 1, a first filter plate 13 is provided at the top of the filter cartridge 12, a second filter plate 14 is provided at the bottom of the filter cartridge 12, the outlet pipe 5 cooperates with the first filter plate 13 and the second filter plate 14, a plurality of filter holes 15 are provided inside the first filter plate 13 and the second filter plate 14, and a limit ring 16 is fixedly installed on the inner wall on both sides of the filter cartridge 1, and a positioning groove 17 is provided inside the limit ring 16. A mounting plate 18 is fixedly installed on both sides of the filter element 12, and a positioning rod 19 is fixedly installed on the bottom of the mounting plate 18. The positioning rod 19 cooperates with the positioning groove 17, and the inner walls on both sides of the air inlet cover 2 are fixed. A pressure block 20 is installed, which cooperates with the mounting plate 18, wherein the filter holes 15 inside the first filter plate 13 and the second filter plate 14 are staggered. After the larger water vapor in the oxygen passes through the filter holes 15 inside the first filter plate 13, it will be blocked by the second filter plate 14 to filter out the larger water droplets, while the smaller water mist will not be blocked by the first filter plate 13 and the second filter plate 14. The functions of the limiting ring 16, the positioning groove 17, the mounting plate 18 and the positioning rod 19 are to facilitate the installation and positioning of the filter element 12, and also to facilitate its disassembly. The function of the pressure block 20 is to limit and fix the mounting plate 18.

[0023] In summary, when the high-frequency and high-flow humidifier connecting tube is in use, the air humidified by the high-frequency and high-flow humidifier enters the air inlet hood 2 through the air inlet pipe 3, and then passes through the first filter plate 13 and the second filter plate 14 to filter out larger water droplets. The humidified air is discharged through the air outlet pipe 5 and inhaled by the patient. The accumulated water filtered out by the first filter plate 13 and the second filter plate 14 falls into the bottom of the filter cartridge 1, and is absorbed by the absorbent cotton 6. The cotton strip 10 and the dripper 11 will use the capillary effect to guide the accumulated water into the collection bottle 9 through the drain pipe 7 for collection, which can effectively avoid residual accumulated water in the filter cartridge 1 and avoid the accumulated water entering the air outlet pipe 5 and causing the patient to choke on water.

[0024] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
