Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical equipment, and in particular to a multifunctional nasal high-flow oxygen delivery tube. Background Technology
[0002] For patients with severe oxygen dependence, high-flow nasal cannula oxygen therapy is typically used to provide sufficient oxygen. This method requires a nasal cannula, through which a high-flow-rate mixture of air and oxygen at a specific concentration is delivered directly to the patient without the need for a seal. Because these patients often have high oxygen demands and are frequently unconscious, existing high-flow nasal cannula tubes have a fixture that presses against the patient's lips for extended periods, causing pressure injuries and reducing patient comfort. Furthermore, when patients are agitated, the tube often falls out, or the oxygen outlet shifts or tilts upwards, resulting in ineffective oxygen delivery and posing a life-threatening risk. Therefore, a multifunctional high-flow nasal cannula is needed. Utility Model Content
[0003] The purpose of this invention is to provide a multifunctional nasal high-flow oxygen delivery tube to solve the technical problem of pressure injury caused to patients by prolonged fixation of existing nasal high-flow oxygen delivery tubes.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A multifunctional nasal high-flow oxygen delivery tube includes an oxygen delivery component and a fixing component, with one end of the oxygen delivery component connected to the middle of the fixing component;
[0006] The fixing component includes a fixing member and an elastic band. The two ends of the elastic band are respectively connected to the two ends of the fixing member. The middle and two ends of the bottom end of the fixing member are respectively provided with pressure-reducing cotton pads. A connecting block is provided at the top of one side of the fixing member. A connecting hole is opened in the middle of the connecting block, and a thin rope is provided in the connecting hole.
[0007] The oxygen delivery assembly includes a nasal cannula, a tubing, and a connector. The nasal cannula is connected to the middle of the fixing member. Two nasal plugs are provided on one side of the nasal cannula. The two nasal plugs pass through one side of the fixing member. A limiting component is provided between the two nasal plugs and is located on one side of the fixing member. One end of the tubing is connected to one end of the nasal cannula, and the other end of the tubing is connected to one end of the connector. An anti-backflow water collection bottle is connected to the end of the tubing near the connector.
[0008] Furthermore, the fixing member includes a main fixing plate, with connectors at both ends of the main fixing plate, a side fixing plate on one side of the main fixing plate, and a connecting ring on one side of the side fixing plate.
[0009] Furthermore, the middle part of the bottom end of the main fixing plate is set in an arc shape, and the pressure-reducing cotton pad is set at the arc shape in the middle part of the bottom end of the main fixing plate.
[0010] Furthermore, the connector is provided with a small cylinder, the top of the small cylinder is provided with a large cylinder, the pressure-relieving cotton pad is provided at the bottom of the connector, and a connecting buckle is provided on the small cylinder, which is connected to the elastic band.
[0011] Furthermore, a circular strip is provided on the outer side of the elastic band, and the circular strip is made of foam.
[0012] Furthermore, the limiting component includes a limiting post and a limiting plate. One end of the limiting post is connected to the side fixing plate, and the limiting plate is connected to the other end of the limiting post. The limiting plate is configured to be arc-shaped.
[0013] Furthermore, the nasal cannula is configured as a cannula with one open end and the other closed end. The nasal cannula has inwardly recessed depressions near the open end and near the closed end. The connecting ring is connected to the depressions. The open end of the nasal cannula is threadedly connected to the flexible tube.
[0014] Furthermore, the connector is threadedly connected to the hose, and the connector is connected to the anti-backflow water collection bottle through a drainage tube.
[0015] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:
[0016] 1. This utility model reduces the pressure of the fixation on the patient's lips by placing pressure-relieving cotton pads at the middle and both ends of the bottom of the fixation piece to contact the patient's skin, thus preventing pressure injury caused by prolonged fixation.
[0017] 2. This utility model features a connecting block with a connecting hole in the middle. A thin rope is placed inside the connecting hole and secured by wrapping the rope around the head. This effectively fixes the oxygen supply tube, preventing it from shifting or coming off. This prevents the oxygen supply tube from falling off or the oxygen outlet from shifting or tilting up when the patient is agitated, thus avoiding ineffective oxygen inhalation and posing a life-threatening risk to the patient.
[0018] 3. This utility model sets a limiting component between the two nasal plugs. The limiting component is used to limit the nasal plug from entering the patient's nostril too far and causing discomfort to the patient. While ensuring effective oxygen inhalation, it can also reduce the pressure on the nasal outlet plane and avoid pressure injury. Attached Figure Description

Detailed Implementation
[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of this utility model, and these aspects can be achieved even without these specific details.
[0026] like Figure 1As shown, a multifunctional nasal high-flow oxygen delivery tube includes an oxygen delivery component 10 and a fixing component 20. One end of the oxygen delivery component 10 is connected to the middle of the fixing component 20. The fixing component 20 includes a fixing member 21 and an elastic band 22. The two ends of the elastic band 22 are respectively connected to the two ends of the fixing member 21. Pressure-reducing cotton pads 23 are respectively provided at the middle and two ends of the bottom end of the fixing member 21. The fixing member presses on the patient's lips for a long time, which can easily cause pressure injury to the patient's lips and reduce the patient's comfort. The pressure-reducing cotton pads 23 can reduce the pressure of the fixing member on the patient's lips. A connecting block 24 is provided at the top of one side of the fixing member 21. A connecting hole 25 is opened in the middle of the connecting block 24. A thin rope 26 is provided in the connecting hole 25. During use, when the patient is restless, the oxygen often falls out or the oxygen outlet shifts or tilts up. In case of ineffective oxygen inhalation, the oxygen delivery tube is effectively secured by wrapping the thin rope 26 on the connecting block 24 around the patient's head, preventing it from shifting or coming off. The oxygen delivery assembly 10 includes a nasal cannula 11, a flexible tube 12, and a connector 13. The nasal cannula 11 is connected to the middle of the fixing member 21. Two nasal plugs 14 are provided on one side of the nasal cannula 11, and each nasal plug 14 is connected to the nasal cannula 11. One end of each nasal plug 14 has an air outlet. The two nasal plugs 14 are positioned through one side of the fixing member 21, and a limiting component 16 is provided between the two nasal plugs 14, with the limiting component 16 located on one side of the fixing member 21. One end of the flexible tube 12 is connected to one end of the nasal cannula 11, and the other end of the flexible tube 12 is connected to one end of the connector 13. The end of the flexible tube 12 near the connector 13 is connected to an anti-backflow water collection bottle 17 for collecting condensate.
[0027] like Figure 2As shown, the fixing member 21 includes a main fixing plate 211, with connectors 212 at both ends of the main fixing plate 211. A side fixing plate 213 is provided on one side of the main fixing plate 211, and a connecting ring 214 is provided on one side of the side fixing plate 213 for connecting the nasal cannula. The middle part of the bottom end of the main fixing plate 211 is arc-shaped to fit the patient's lips. The pressure-reducing cotton pad 23 is located at the arc-shaped part of the bottom end of the main fixing plate 211 to reduce the pressure of the main fixing plate 211 on the patient's lips. The connector 212 is provided with a small cylinder 215, and a large cylinder 216 is provided at the top of the small cylinder 215. The diameter of the large cylinder 216 is larger than that of the small cylinder 215 to prevent the connecting buckle 217 from slipping off the small cylinder 215. The pressure-relieving cotton pad 23 is provided at the bottom of the connector 212. The connector 212 can easily cause pressure injury to the patient's skin if it is fixed for a long time. The pressure-relieving cotton pad reduces the pressure of the connector on the patient's skin. The small cylinder 215 is provided with a connecting buckle 217, which is connected to the elastic band 22. A round strip 221 made of foam is provided on the outer side of the elastic band 22. Since the elastic band 22 can cause marks on the patient's ears if it is fixed for a long time, the round foam strip on the outer side of the elastic band 22 can prevent slippage and fix the device.
[0028] In an embodiment of this utility model, the limiting component 16 includes a limiting post 161 and a limiting plate 162. One end of the limiting post 161 is connected to the side fixing plate 213, and the limiting plate 162 is connected to the other end of the limiting post 161. The limiting post 161 is shorter than the length of the nasal plug 14. The limiting plate 162 is arc-shaped. When in use, the limiting plate 162 contacts the patient's columella, at which point the nasal plug just enters the patient's nose, preventing the nasal plug from entering the patient's nose too far and causing discomfort. This ensures effective oxygen intake for the patient and reduces the pressure on the nasal outlet plane, avoiding pressure injury.
[0029] like Figure 3As shown, the nasal cannula 11 is configured as a cannula with one open end and the other closed end. The nasal cannula 11 has inwardly recessed depressions 15 near the open end and near the closed end. The connecting ring 214 is connected to the depression 15. The inner diameter of the connecting ring is smaller than the outer diameter of the nasal cannula and larger than the outer diameter of the depression to ensure that the connecting ring does not slip off. The open end of the nasal cannula 11 is threadedly connected to the flexible tube 12. The connector 13 is threadedly connected to the hose 12. The threaded connection facilitates the connection of the nasal cannula to the hose and the connector to the hose, and also facilitates later maintenance. The connector 13 is connected to the anti-backflow water collection bottle 17 through the drainage tube 18. The anti-backflow water collection bottle 17 includes a bottle cap 171 and a water collection bottle 172. An upper connecting tube 173 is provided in the middle of the upper end of the bottle cap 171, and the upper connecting tube 173 is connected to the drainage tube 18. A lower connecting tube 174 is provided in the middle of the lower end of the bottle cap 171, and the lower connecting tube 174 is threadedly connected to the water collection bottle 172, which facilitates the removal of the water collection bottle 172 and the treatment of the water in the water collection bottle 172. A baffle plate 175 is provided inside the lower connecting pipe 174. The baffle plate 175 is circular, and its circumferential sidewall is connected to the inner sidewall of the lower connecting pipe 174. A right through hole 176 is provided on the right side of the baffle plate 175. A spring 177 is provided below the baffle plate 175. The spring 177 is a semi-circular ring, and its two ends are respectively connected to the inner sidewall of the lower connecting pipe 174. A central through hole 178 is provided in the middle of the spring 177, and a left through hole 179 is provided on the left side of the spring 177. The spring 177 can be flipped under force, and the central through hole 178 of the spring 177 can tightly abut against the middle of the baffle plate 175 to form a seal. In actual use, the end of the hose 12 near the connector 13 may droop downwards. Moreover, when the patient is receiving high-flow oxygen, humidification and heating are required, which will generate condensation. The condensation will accumulate at the drooping part of the hose. If medical staff are busy and do not have time to empty it, too much condensation may rush into the patient's nasal cavity and airway, aggravating the patient's lung infection and prolonging the hospitalization period. By installing a drainage tube on the hose, the condensation at the drooping part of the hose can be effectively directed into the anti-backflow collection bottle, and the water flows downhill. When condensate flows from the hose through the drain pipe into the anti-backflow collection bottle, it flows into the reed through the right through-hole on the right side of the baffle plate inside the lower connecting pipe. The reed, under the force of the condensate, flips downwards, allowing the condensate to flow into the collection bottle through the central through-hole and the left through-hole on the left side of the reed. When the internal pressure of the collection bottle becomes too high, the reed flips upwards, and the central through-hole of the reed presses tightly against the baffle plate, sealing the central through-hole. This prevents the condensate from flowing back into the pipe and into the collection bottle.
[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
