Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a retractable nasal cannula. Background Technology

[0002] A nasal cannula is a thin, flexible tube that typically wraps around a patient's head and has two parts (also called nasal plugs or gears) that insert into the nostrils to deliver extra oxygen to the patient's nose. It is primarily used to treat respiratory illnesses or conditions of insufficient oxygen, helping those who have difficulty breathing due to medical conditions or other reasons.

[0003] When using a nasal cannula, one end is typically connected to the outlet of the breathing device, while the other end is gently inserted into the patient's nostril through a nasal plug. This allows oxygen to be effectively guided into the patient's airway, providing the necessary high concentration of oxygen.

[0004] During the use of nasal cannulas, most patients require long-term oxygen therapy. However, due to the limited length of nasal cannulas, they are primarily designed for use in bed. When the oxygen device is located at one end of the bed, and the patient needs to move around or sit up at the other end, the length of the nasal cannula is often insufficient to allow the patient to change position freely. This limits the patient's range of motion and causes inconvenience to their daily activities. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a retractable nasal cannula that can be extended to a certain extent so that patients can move freely and change positions within a certain range while in bed.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a retractable nasal cannula, comprising several flexible tubes and several telescopic tubes, the telescopic tubes being spaced apart from the several flexible tubes, the two ends of the telescopic tubes being fixedly connected and communicating with the adjacent ends of two adjacent flexible tubes, a fixing component being connected between the two adjacent flexible tubes, and a detector and an adjustment component being connected to the ends of the two flexible tubes located at opposite ends, the detector being connected to the air outlet of the breathing device.

[0007] Furthermore, the telescopic tube is a corrugated pipe.

[0008] Furthermore, a branch pipe is fixedly connected to the side wall of the hose connected to the testing instrument, and the other end of the branch pipe is fixedly connected to a humidifier.

[0009] Furthermore, the fixing component includes an L-shaped connecting rod and a fixing sleeve. The L-shaped connecting rod and the fixing sleeve are respectively fixedly connected to the side walls of the adjacent ends of two adjacent hoses. An insert is fixedly connected to the inner wall of the L-shaped connecting rod at the end away from the hose, and the insert is slidably connected to the inner wall of the fixing sleeve.

[0010] Furthermore, a magnetic block is fixedly connected to the inner wall of the fixing sleeve, the magnetic block is fixedly connected to the outer wall of the adjacent flexible tube, and the magnetic block is magnetically connected to the adjacent insertion block.

[0011] Furthermore, the adjustment assembly includes a bottom clamping plate, a top clamping plate, and a movable clamping plate. A support frame is fixedly connected between the bottom clamping plate and the top clamping plate. Sliding holes are opened through both ends of the movable clamping plate, and the two sliding holes are slidably connected to the two support frames respectively. A threaded rod is opened through the side of the top clamping plate away from the bottom clamping plate. The threaded rod abuts against the movable clamping plate and is threadedly connected to the top clamping plate. The end of the flexible hose away from the detector is located between the bottom clamping plate and the movable clamping plate, and between the two support frames.

[0012] Furthermore, a stop block is fixedly connected to one end of the threaded rod near the movable clamping plate, the other side of the stop block abuts against the movable clamping plate, and a hand-tightening block is fixedly connected to the other end of the threaded rod away from the stop block.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This type of retractable nasal cannula, through the spacing of multiple flexible tubes and telescopic tubes, can extend the length of the entire nasal cannula to a certain extent. This makes it convenient for patients to move their position in bed or get up without the nasal cannula being pulled, thus improving the convenience and applicability of the nasal cannula.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1 to 4 A retractable nasal cannula includes several flexible tubes 1 and several telescopic tubes 2. The telescopic tubes 2 are spaced apart from the several flexible tubes 1. The two ends of the telescopic tubes 2 are fixedly connected and communicated with the adjacent ends of two adjacent flexible tubes 1. A fixing component is connected between the two adjacent flexible tubes 1. The ends of the two flexible tubes 1 located at their ends, which are far apart from each other, are respectively connected to a detector 3 and an adjustment component. The detector 3 is connected to the air outlet of the breathing device.

[0022] like Figures 1 to 4 As shown, the retractable nasal cannula of this invention is similar in structure to existing nasal cannulas. The main improvement of this invention is that the nasal cannula can be appropriately extended, facilitating patient movement in bed. Figures 1 to 4 As shown, in this utility model, when the patient needs to get out of bed and move around appropriately at the bedside, the binding of the telescopic tube 2 can be released through the fixing component, allowing the telescopic tube 2 to unfold and thus extend the length of the entire nasal cannula. When the patient is lying in bed and only needs to make small movements, the binding of a single telescopic tube 2 or part of the telescopic tube 2 can be released to appropriately extend the length of the nasal cannula, preventing the patient from pulling on the nasal cannula when moving in bed. The end detection 3 is existing technology, and a multi-functional detection instrument can be used to measure various parameters such as oxygen content, flow rate, and pressure at the outlet of the breathing device, so as to monitor the oxygen flow state in the nasal cannula. The adjustment component can close the end of the nasal cannula when it is not in use, reducing the contact between the inside of the nasal cannula and the air, thereby reducing the aging rate of the nasal cannula, helping to extend the service life of the nasal cannula, and reducing the frequency and cost of replacing the nasal cannula. In addition, it should be noted that both the flexible tube 1 and the telescopic tube 2 can be bent appropriately to prevent breakage during use.

[0023] like Figure 1 As shown, the telescopic tube 2 is a corrugated tube. Using a corrugated tube as the telescopic tube 2 makes it easier to reduce the volume occupied when retracted, thus improving the convenience of using the nasal cannula.

[0024] like Figure 1As shown, a branch pipe 4 is fixedly connected to and communicates with the side wall of the flexible tube 1 connected to the detector 3, and a humidifier 5 is fixedly connected to and communicates with the other end of the branch pipe 4. The humidifier 5 is installed on the flexible tube 1 near the detector 3 to properly humidify the oxygen flowing in the flexible tube 1, so as to avoid excessive dryness affecting the patient's breathing.

[0025] like Figure 1 and Figure 2 As shown, the fixing assembly includes an L-shaped connecting rod 6 and a fixing sleeve 7. The L-shaped connecting rod 6 and the fixing sleeve 7 are respectively fixedly connected to the side walls of the adjacent ends of two adjacent hoses 1. An insert 8 is fixedly connected to the inner wall of the end of the L-shaped connecting rod 6 away from the hose 1, and the insert 8 is slidably connected to the inner wall of the fixing sleeve 7. When it is not necessary to extend the telescopic tube 2, the telescopic tube 2 can be retracted first, and the insert 8 at the end of the L-shaped connecting rod 6 can be inserted into the adjacent fixing sleeve 7, thereby connecting and fixing the hoses 1 at both ends of the telescopic tube 2, avoiding the nasal cannula from being too long and affecting its use. The reverse operation can release the restraint on the telescopic tube 2, thereby pulling the telescopic tube 2 to extend it.

[0026] like Figure 1 and Figure 2 As shown, a magnetic block 9 is fixedly connected to the inner wall of the fixing sleeve 7. The magnetic block 9 is fixedly connected to the outer wall of the adjacent flexible tube 1, and the magnetic block 9 is magnetically connected to the adjacent insert block 8. When the insert block 8 is inserted into the fixing sleeve 7, the magnetic attraction with the magnetic block 9 can improve the connection between the L-shaped connecting rod 6 and the fixing sleeve 7, making it less likely for the L-shaped connecting rod 6 and the fixing sleeve 7 to fall off under slight pulling. When a larger pull occurs, the magnetic block 9 separates from the insert block 8, thereby separating the L-shaped connecting rod 6 from the fixing sleeve 7. The telescopic tube 2 can then be extended appropriately, preventing the entire nasal cannula from being pulled and damaged, and improving the stability and safety of the nasal cannula.

[0027] like Figures 1 to 4 As shown, the adjustment assembly includes a bottom clamping plate 10, a top clamping plate 11, and a movable clamping plate 12. A support frame 13 is fixedly connected between the bottom clamping plate 10 and the top clamping plate 11. Sliding holes 101 are provided through both ends of the movable clamping plate 12. The two sliding holes 101 are slidably connected to the two support frames 13 respectively. A threaded rod 14 is provided through the side of the top clamping plate 11 away from the bottom clamping plate 10. The threaded rod 14 abuts against the movable clamping plate 12 and is threadedly connected to the top clamping plate 11. The end of the flexible hose 1 away from the detector 3 is located between the bottom clamping plate 10 and the movable clamping plate 12, and between the two support frames 13. When not using the nasal cannula, the end of the nasal cannula tubing 1 can be placed between the bottom clamp 10 and the movable clamp 12, and the threaded rod 14 can be rotated to gradually move towards the bottom clamp 10 within the top clamp 11, and push the movable clamp 12 to gradually move towards the bottom clamp 10, thereby clamping and fixing the end of the tubing 1, which can reduce the amount of air entering the nasal cannula and causing it to age.

[0028] like Figures 1 to 4 As shown, a stop block 15 is fixedly connected to one end of the threaded rod 14 near the movable clamping plate 12, and the other side of the stop block 15 abuts against the movable clamping plate 12. A hand-tightening block 16 is fixedly connected to the other end of the threaded rod 14 away from the stop block 15. When rotating the threaded rod 14, the hand-tightening block 16 makes it easier to turn the threaded rod 14. At the same time, the other end of the threaded rod 14 abuts against the movable clamping plate 12 through the stop block 15, increasing the contact area with the movable clamping plate 12 and making the movable clamping plate 12 less prone to compression deformation.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
