Description

Technical Field

[0001] This invention relates to the field of oxygen supply-assisted fixation technology, specifically to a portable intelligent nasal cannula fixation device for use in high-altitude environments. Background Technology

[0002] Nasal cannula oxygen therapy is a common method of supplemental oxygen supply, widely used in home oxygen therapy, portable oxygen supply, and high-altitude travel or work scenarios. It typically connects to an oxygen supply device via a flexible catheter, which is then routed around the head and face to position the nasal cannula in the nasal cavity for continuous oxygen delivery. The low oxygen and low temperature characteristics of high-altitude environments place higher demands on the continuity of oxygen supply, stability of wear, and user comfort.

[0003] Existing technologies, such as the NATAKU Oxygen Cannula Headband, involve wearing a flexible headband on the user's head and using the placement or limiting points on the headband to constrain the path of the oxygen nasal cannula, ensuring its relatively stable placement along the sides of the face and head. Simultaneously, adjustable structures and flexible, breathable materials are used to reduce the pressure pain, discomfort, and slippage issues associated with traditional ear-wrap designs. Essentially, the working principle of this type of product is to use the headband itself to support, guide, and maintain the position of the nasal cannula, thereby achieving basic fixation of the nasal cannula in portable oxygen inhalation scenarios.

[0004] However, in actual use of the aforementioned headband-type nasal cannula fixation products, because they mainly rely on a flexible headband to restrict and maintain the cannula's path, lacking a dedicated clamping and limiting structure in the vicinity of the nasal cannula, the tip of the nasal cannula is still prone to shifting in high-altitude, low-temperature conditions and during activity, thus affecting wearing stability and continuous oxygen delivery. Furthermore, the disclosed structure of these products prioritizes comfortable wear and cannula retention, making it difficult to simultaneously address targeted protection of the mouth and nose areas, and thus failing to reduce the direct irritation of the nose by cold air during use. Therefore, it is necessary to propose a portable intelligent nasal cannula fixation device for high-altitude environments to solve the above problems. Summary of the Invention

[0005] To address the aforementioned issues, this invention provides a portable intelligent nasal cannula fixing device for use in high-altitude environments. This device uses a clamping component to quickly clamp and stably limit the nasal cannula, and a windproof component to form a protective area around the mouth and nose. This solves the problems of the nasal cannula easily shifting during use in high-altitude, low-temperature, and windy environments, as well as the nasal area being easily irritated by cold winds.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: A portable intelligent nasal cannula fixing device for high-altitude environments includes a nasal cannula and a headband, both ends of which are detachably connected to fixing plates; a clamping assembly for clamping the nasal cannula is provided between the fixing plates, the clamping assembly including a first guide plate, and second guide plates symmetrically arranged between the fixing plates, each of the second guide plates being fixedly connected to its adjacent fixing plate, each of the second guide plates having a second guide groove, each of the second guide grooves having a second slider slidably fitted within it, each of the second sliders having a clamping plate fixedly connected to one side wall, the clamping plates abutting against the nasal cannula; each of the second sliders having a first slider fixedly connected to the other side wall, the first guide plates having symmetrically opened first guide grooves, each of the first sliders having a slidably fitted with its adjacent first guide groove; an adjustment assembly for adjusting the height of the first guide plate is provided on the side wall of the fixing plate, and a windproof assembly for wind protection at the mouth and nose is provided on the side wall of the second guide plate.

[0007] The technical principles of the above solution are as follows: In use, the adjustment component moves the first guide plate vertically. As the first guide plate moves, the first guide groove guides the first slider, which slides against it, at an angle. The first slider is fixedly connected to the second slider, which in turn slides against the second guide groove on the second guide plate. The second guide groove restricts the movement of the second slider, allowing it to move only horizontally. This prevents the first slider from moving vertically with the first guide plate, thus converting the force generated by the vertical movement of the first guide plate into the lateral displacement of the first slider via the first guide groove. When the first guide plate moves downward, the two first sliders move closer together, causing the second slider and clamping plate to move closer simultaneously to clamp and fix the nasal cannula. When the first guide plate moves upward, the two first sliders move further apart, causing the second slider and clamping plate to separate simultaneously, allowing the nasal cannula to be loosened and adjusted. After the nasal cannula is clamped and fixed, the windproof component on the side wall of the second guide plate is located outside the mouth and nose, forming a protective area for the mouth and nose. This stabilizes the nasal cannula while reducing the direct stimulation of cold wind on the user's mouth and nose in high-altitude environments.

[0008] The above approach has the following beneficial effects: 1. The present invention moves the first guide plate downward to drive the first slider to slide and retract in the first guide groove, and further drives the second slider to move in the second guide groove, so that the two clamping plates move towards the nasal cannula at the same time, thereby enabling the nasal cannula to be quickly clamped and stably limited, reducing the risk of displacement of the nasal cannula during wearing and activities.

[0009] 2. The present invention centrally arranges the clamping component, adjustment component and windproof component between the fixing plate. During the wearing process, the user can complete the fixation and position adjustment of the nasal cannula around the same area. The structure is more compact, the adjustment action is more concentrated, and the use is more convenient.

[0010] 3. By setting up windproof components, the present invention can form a flexible protective area around the nose, blocking cold winds in high-altitude environments, reducing discomfort caused by cold stimulation to the nose, and improving the user's wearing comfort in high-altitude environments.

[0011] Furthermore, the adjustment assembly includes an adjustment groove on the side wall of the fixed plate, and an adjustment rod is slidably fitted in each adjustment groove. The other end of each adjustment rod is fixedly connected to the first guide plate. A segmented positioning structure is provided between the adjustment groove and the adjustment rod.

[0012] Beneficial effects: By moving the adjusting rod within the adjusting groove, the gap between the clamping plates can be precisely adjusted to accommodate nasal cannulas of different thicknesses. The segmented positioning structure can stably lock the adjusting rod after adjustment, reducing height shift caused by shaking, collision, or long-term wear, thereby reducing the frequency of repeated corrections and improving the consistency of the fixed state.

[0013] Furthermore, the windproof component includes an airbag frame fixedly connected to the side wall of the second guide plate. The airbag frame has a mounting hole in the middle, and the nasal cannula slides into the mounting hole. Windproof cloth is fixedly connected to the gaps in the airbag frame.

[0014] Beneficial effects: By setting an airbag frame with mounting holes on the side wall of the second guide plate and setting a windproof cloth in the gap of the airbag frame, a secondary guide and auxiliary limit can be formed on the section of the nasal cannula near the nose after the nasal cannula passes through the mounting hole, while a flexible protective cover is formed on the outside of the mouth and nose. This not only helps to reduce the direct impact of external airflow on the nose, but also helps to reduce the amount of deviation when the nasal cannula swings near the nose, taking into account the stability of the cannula, the comfort of the fit, and the environmental protection effect.

[0015] Furthermore, the sidewall of the fixed plate is provided with a piston assembly for inflating and deflating the airbag frame. The piston assembly includes several piston cylinders and U-shaped piston rods. The piston cylinders are all fixedly connected to their adjacent fixed plates and are detachably connected to the headband. One end of each U-shaped piston rod passes through the adjacent piston cylinder and is fixedly connected to a piston plate inside the piston cylinder. The piston plate slides vertically with the inner sidewall of the piston cylinder. The end of each U-shaped piston rod away from the piston plate passes through the bottom of the fixed plate and is fixedly connected to the adjustment groove inside the adjustment rod. Each piston cylinder has a through hole at the bottom, which communicates with the airbag frame. An air hole is opened at the top of the piston cylinder.

[0016] Beneficial effects: By connecting the U-shaped piston rod to the adjusting rod, the piston plate can be driven simultaneously when adjusting the height of the first guide plate, allowing gas to flow between the piston cylinder and the airbag frame through the through hole, thus integrating the clamping and adjusting action with the inflation and deflation action of the airbag frame. In this way, the windproof component can be deployed simultaneously when the nasal cannula is clamped, and the windproof component can be retracted simultaneously when the nasal cannula is released, reducing the need for separate inflation or deflation operations. This simplifies the usage steps and also helps to shorten the switching time between wearing and storing.

[0017] Furthermore, the headband is divided into several symmetrical support sections, and adjacent support sections can be detachably connected.

[0018] Beneficial effects: The headband is made of several detachable support sections spliced ​​together to form an overall wearing structure. When worn, it can provide continuous support for the fixing plates on both sides, ensuring the stability of the relative position of the clamping component and the windproof component in front of the mouth and nose. When not in use, each support section can be disassembled and stacked or stored together to reduce the overall volume, making it easy to carry and store for spares. It also makes it easy to replace and maintain worn or damaged individual parts.

[0019] Furthermore, flexible anti-slip pads are fixedly connected to the side walls of the clamping plate near the nasal cannula.

[0020] Beneficial effects: The flexible anti-slip pad can increase the contact area and improve friction when holding the nasal cannula, reducing the possibility of the cannula slipping when it is pulled, shaken or the wearer moves; at the same time, the flexible contact layer can buffer the clamping force and reduce the local compression and wear of the rigid clamping plate on the outer wall of the nasal cannula, thus taking into account the clamping stability, cannula protection and reliability of repeated use.

[0021] Furthermore, the headband is fixedly connected to a controller, and the flexible anti-slip pads are all fixedly connected to deformation sensors. The deformation sensors are all electrically connected to the controller. The headband sidewall is fixedly connected to a vibration motor, which is electrically connected to the controller.

[0022] Beneficial effects: The deformation sensor can detect the pressure deformation state of the flexible anti-slip pad and transmit the detection results to the controller. The controller determines whether the current clamping force is too loose or too tight based on the deformation, and controls the vibration motor to issue a reminder when there is an abnormality. This helps the user to correct the clamping state in time, avoids the easy displacement of the catheter due to insufficient clamping, and also avoids excessive pressure on the catheter or discomfort due to excessive clamping, thus improving the fixation quality and human-machine interaction.

[0023] Furthermore, a flexible layer is fixedly connected to the inner wall of the headband.

[0024] Beneficial effects: The flexible layer on the inner wall of the headband can form a flexible buffer at the contact point between the headband and the head, dispersing the pressure of the headband on the local skin and reducing the pressure pain during long-term wear; at the same time, the flexible layer can also increase the friction between the headband and the head, reducing the risk of the headband slipping due to sweating, movement or turning of the head, thus helping to maintain the stability and comfort of the entire fixation device.

[0025] Furthermore, one of the windproof fabric pieces is fixedly connected to an exhaust one-way valve, and the gas flow direction is from the inside of the cover formed by the airbag frame and the windproof fabric to the outside.

[0026] Beneficial effects: The one-way exhaust valve allows the gas inside the mask to be discharged outwards and prevents cold air from entering the mask from the outside. This provides an exhaust channel for the user's exhalation, reducing the problems of moisture, stuffiness, or stagnation of exhaled air inside the mask. At the same time, the one-way exhaust method can maintain the mask's blocking effect on the outside airflow as much as possible, which helps to ensure smooth exhalation while maintaining the windproof effect and comfort of the mouth and nose.

[0027] Furthermore, a sealing ring is fixedly connected at the point where the U-shaped piston rod passes through the piston cylinder.

[0028] Beneficial effects: After installing a sealing ring at the penetration point between the U-shaped piston rod and the piston cylinder, the reciprocating motion of the U-shaped piston rod can be sealed, reducing air leakage at the penetration point during the operation of the piston assembly, and making the piston plate's pushing or sucking action on the gas inside the cylinder more effective; this is more conducive to ensuring the inflation and deflation response and deployment stability of the airbag frame, and avoiding the impact of insufficient sealing on the performance of the windproof component.

[0034] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0036] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0037] The following detailed description illustrates the specific implementation method: Example 1: As attached Figure 1 , Figure 2 and Figure 3 As shown: A portable intelligent nasal cannula fixation device for high-altitude environments includes a nasal cannula 17 and a headband 1. Both ends of the headband 1 are detachably connected to fixing plates 2. A clamping assembly for clamping the nasal cannula 17 is provided between the fixing plates 2.

[0038] The clamping assembly includes a first guide plate 3, and second guide plates 5 are symmetrically arranged between the fixed plates 2. Each second guide plate 5 is integrally formed with its adjacent fixed plate 2. Each second guide plate 5 has a second guide groove 6. Each second guide groove 6 has a second slider 8 that slides within it. Each side wall of the second slider 8 has a clamping plate 11 integrally formed, and each clamping plate 11 abuts against the nasal cannula 17. Each other side wall of the second slider 8 has a first slider 7 integrally formed. The first guide plate 3 has symmetrically formed first guide grooves 4, and each first slider 7 slides within its adjacent first guide groove 4.

[0039] Specifically, in use, first wear the headband 1 and pass the nasal cannula 17 between the two clamping plates 11. Then, drive the first guide plate 3 to move downward in the vertical direction by external force. When the first guide plate 3 moves downward, the first guide groove 4 provides oblique guidance to the first slider 7. However, the first slider 7 cannot move vertically with the first guide plate 3 due to the sliding restriction of the second slider 8 in the second guide groove 6. Therefore, the first slider 7 moves towards the center in the horizontal direction and drives the second slider 8 and the clamping plate 11 to move towards each other synchronously, thereby clamping and fixing the nasal cannula 17. When it is necessary to disassemble or readjust the position of the nasal cannula 17, drive the first guide plate 3 to move upward, and the two clamping plates 11 separate accordingly to release the nasal cannula 17.

[0040] like Figure 2 and Figure 3 As shown, the side wall of the fixed plate 2 is provided with an adjustment component for adjusting the height of the first guide plate 3.

[0041] The adjustment assembly includes an adjustment groove 9 on the side wall of the fixed plate 2, and an adjustment rod 10 is slidably fitted in the adjustment groove 9. The other end of the adjustment rod 10 is bolted to the first guide plate 3.

[0042] A segmented positioning structure is provided between the adjusting groove 9 and the adjusting rod 10. In this embodiment, the segmented positioning structure is a ball plunger. Its principle is to use the internal spring of the ball plunger to push out the ball head and cooperate with the positioning hole on the external mating part. Under the action of external force, the ball head can retract and disengage from the current positioning hole, and enter the next positioning hole under the action of spring reset, thereby realizing segmented positioning. This is the prior art, and will not be described in detail in this embodiment.

[0043] Specifically, the user can push the adjustment rod 10 up and down along the adjustment groove 9. During the movement, the adjustment rod 10 drives the first guide plate 3 to change its height, so that the clamping force of the clamping plate 11 is compatible with the model of the nasal cannula 17. After adjusting to the appropriate height, the segmented positioning structure limits and locks the adjustment rod 10, so that the first guide plate 3 is kept at the corresponding height, preventing it from shifting on its own due to shaking during wear.

[0044] like Figure 2 and Figure 4As shown, the second guide plate 5 has a windproof component on its side wall for wind protection at the mouth and nose.

[0045] The windproof component includes an airbag frame 12 bonded to the side wall of the second guide plate 5. The airbag frame 12 has a mounting hole in the middle. The nasal cannula 17 slides in the mounting hole. Windproof cloth 13 is bonded to the gaps of the airbag frame 12.

[0046] Specifically, during use, the nasal cannula 17 is first passed through the mounting hole in the middle of the airbag frame 12, and then the nasal cannula 17 continues to be positioned between the two clamping plates 11. After the clamping plates 11 have fixed the nasal cannula 17, the mounting hole can provide auxiliary restraint for the position of the nasal cannula 17 near the nose. The airbag frame 12 is located around the mouth and nose, and the windproof cloth 13 is sealed in the gap of the airbag frame 12, thereby forming a windproof area on the outside of the mouth and nose to reduce the direct blow of cold wind on the mouth and nose.

[0047] like Figure 1 and Figure 3 As shown, the side wall of the fixing plate 2 is provided with a piston assembly for inflating and deflating the airbag frame 12.

[0048] The piston assembly includes several piston cylinders 14 and U-shaped piston rods 15. Each piston cylinder 14 is bolted to its adjacent fixed plate 2 and is detachably connected to the headband 1. One end of each U-shaped piston rod 15 passes through the adjacent piston cylinder 14 and is bolted to a piston plate inside the piston cylinder 14. The piston plate slides vertically against the inner wall of the piston cylinder 14. The end of each U-shaped piston rod 15 away from the piston plate passes through the bottom of the fixed plate 2 and is bolted to the adjusting groove 9 and the adjusting rod 10. Each piston cylinder 14 has a through hole 16 at the bottom, which communicates with the airbag frame 12. Each piston cylinder 14 has an air hole at the top.

[0049] Specifically, when the adjusting rod 10 moves along the adjusting groove 9, the U-shaped piston rod 15 moves synchronously with the adjusting rod 10 and drives the piston plate to slide inside the piston cylinder 14. The piston plate pushes the gas inside the piston cylinder 14 to enter the airbag frame 12 through the through hole 16, or to flow back from the airbag frame 12 to the piston cylinder 14. Thus, when the first guide plate 3 moves down and clamps the nasal cannula 17, the airbag frame 12 is inflated simultaneously, causing the airbag frame 12 to unfold and fit close to the mouth and nose. When the first guide plate 3 moves up and releases the nasal cannula 17, the airbag frame 12 is deflated simultaneously, causing the windproof component to retract for easy storage.

[0050] In this embodiment, the clamping component and the adjustment component are used to achieve quick clamping and stable fixation of the nasal cannula 17. The adjustment rod 10 drives the piston component to adjust the clamping state while inflating and deflating the airbag frame 12, so that the windproof component can be deployed or retracted at the same time, thus taking into account both the windproof requirements in the high-altitude environment and the portable storage requirements of the device.

[0051] Example 2: As attached Figure 1 and Figure 4 As shown, the difference from Embodiment 1 is that the headband 1 is divided into several symmetrical support sections, and adjacent support sections are detachably connected.

[0052] Flexible anti-slip pads are adhered to the side walls of the clamping plate 11 near the nasal cannula 17.

[0053] The headband 1 is attached to a controller, and the flexible anti-slip pads are all attached to deformation sensors. The deformation sensors are all electrically connected to the controller. The side wall of the headband 1 is bolted to a vibration motor, which is electrically connected to the controller.

[0054] The inner wall of headband 1 is bonded with a flexible layer.

[0055] One of the windproof fabric pieces 13 is fixedly connected to an exhaust one-way valve, and the gas flow direction is from the inside of the cover formed by the airbag frame 12 and the windproof fabric 13 to the outside.

[0056] A sealing ring is bonded to the U-shaped piston rod 15 where it passes through the piston cylinder 14.

[0057] Specifically, the headband 1 is composed of several support segments spliced ​​together. Before use, it can be assembled into a ring support structure according to wearing needs. When not in use, it can be disassembled and stored.

[0058] A flexible anti-slip pad is provided on the side of the clamping plate 11 near the nasal cannula 17, and a flexible layer is provided on the inner side of the headband 1 to increase friction and reduce the pressure of wearing.

[0059] The deformation sensor is used to detect the deformation of the flexible anti-slip mat under pressure. The controller presets a safe threshold range for the deformation. When the deformation detected by the deformation sensor is below the lower threshold, it is determined that the clamping is too loose, and the vibration motor is controlled to emit intermittent vibration as a reminder. When the deformation is above the upper threshold, it is determined that the clamping is too tight, and the vibration motor is controlled to emit continuous vibration as a reminder. When the deformation returns to the threshold range, the controller controls the vibration motor to stop vibrating.

[0060] The exhaust one-way valve on the windproof cloth 13 is used to exhaust the gas inside the cover to the outside, so as to reduce the accumulation of stuffy air and prevent cold air from flowing back in.

[0061] The sealing ring at the junction of the U-shaped piston rod 15 and the piston cylinder 14 is used to reduce air leakage during piston assembly operation.

[0062] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
