Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a nasal oxygen tube fixing device. Background Art

[0002] A nasal oxygen tube is a medical device that provides oxygen inhalation treatment for patients in need of additional oxygen supply. It is usually made of soft plastic or silicone material and includes a catheter and nasal plugs. One end of the catheter is connected to an oxygen source, and the other end is inserted into the patient's nostrils through two small nasal plugs.

[0003] Common nasal oxygen tubes generally only have nasal plugs and catheters. When in use, the nasal plugs are directly inserted into the nostrils from below the nostrils, and the nasal plugs and catheters cannot be fixed on the patient's face. When the patient moves, the nasal plugs are likely to fall out of the nostrils, resulting in the interruption of oxygen supply and the reduction of curative effect. Moreover, the oxygen supply in hospital wards is generally centralized oxygen supply, and the equipped catheter is very long. When the patient moves, the catheter may be dragged, making it easier for the nasal plugs to fall off.

[0004] After retrieval, the Chinese utility model patent with the publication number CN204890887U discloses a nasal oxygen inhalation tube fixator, which includes a fixed buckle and a blocking rod connected to each other. The fixed buckle is formed by an activity connection component connecting one end of an upper buckle piece and a lower buckle piece. The connection part of the other ends of the upper buckle piece and the lower buckle piece is an opening that keeps freely opening and closing. A first groove is provided on the inner wall of the upper buckle piece, and a second groove is provided on the inner wall of the lower buckle piece, and the first groove and the second groove can be mutually combined into a cavity; the blocking rod is connected to the outer side wall of one of the buckle pieces of the fixed buckle and is integrally formed with the fixed buckle, and the nasal oxygen inhalation tube fixator is installed on the oxygen catheter. This application fixes the catheter at the ear through the fixed buckle and the blocking rod, but the rest of the catheter is not fixed and is easily accidentally touched when the patient moves, resulting in the interruption of oxygen supply and the reduction of treatment effect. Summary of the Utility Model

[0005] Aiming at the above-mentioned prior art, the utility model aims to provide a nasal oxygen tube fixing device, and the main technical problem to be solved is how to store the catheter to avoid being dragged.

[0006] To achieve the above object, the technical solution of the embodiment of the utility model is realized as follows: A nasal oxygen tube fixing device includes an ear hook and a storage device. The ear hook includes a hanging part, and a limiting clip is provided on the hanging part. The hanging part is connected to the nasal oxygen tube through the limiting clip; the storage device includes an installation cylinder with an opening on the side wall. A plurality of limiting blocks are provided on the outer circumference of the installation cylinder, and a limiting opening is provided on the side wall of the limiting block. The installation cylinder is connected to the nasal oxygen tube through the limiting block. A connection channel is provided inside one side of the barrel body of the installation cylinder. A plurality of spring pieces are provided on one side wall of the installation cylinder in the connection channel. A plug-in part is slidably connected in the connection channel of the installation cylinder, and one end of the plug-in part extends out of the connection channel.

[0007] Further, a clamping groove is provided on the side of the installation cylinder away from the connection channel at the opening, and one end of the plug-in member located outside the connection channel abuts against the installation cylinder in the clamping groove.

[0008] Further, the thickness of the plug-in member gradually decreases from the outer end to the inner end.

[0009] Further, the spring piece is arranged on the inner wall of the outer ring of the connection channel of the installation cylinder, and the spring piece inclines towards the opening of the connection channel.

[0010] Further, a sliding channel is opened on the outer side wall of the installation cylinder in the connection channel, the sliding channel is arranged along the circumferential direction of the installation cylinder, and an operating member is slidably connected in the sliding channel of the installation cylinder, and one end of the operating member in the connection channel is fixedly connected to the plug-in member.

[0011] Further, the installation cylinder is made of an elastic material.

[0012] Further, the limit clip is set in a C shape.

[0013] Further, the limit openings are symmetrically arranged on the two side walls of the limit block.

[0014] Further, a number of limit protrusions are provided on the inner wall of the limit clip.

[0015] The beneficial effects of the present utility model are as follows:

[0016] 1. By providing a storage device, the too-long catheter between the oxygen supply instrument and the patient is wound and fixed on the limit block of the storage device, and the storage device is fixed on the hospital bed armrest or the patient's clothes, so as to realize the storage and fixation of the catheter, and avoid the situation that when the patient moves, the too-long catheter will be dragged, causing the catheter to break away from the oxygen supply instrument and the oxygen supply to be interrupted; by providing an ear hook, the catheter is clamped in the limit clip and fixed on the ear, so as to fix the length of the nasal oxygen tube from the patient's nostril to the ear, and further avoid the nasal oxygen tube slipping out of the patient's nostril and preventing oxygen from entering the patient's respiratory tract; through the combined action of the ear hook and the storage device, it is ensured that the nasal oxygen tube can stably supply oxygen to the patient, and thus the stability of the treatment effect is ensured;

[0017] 2. The installation cylinder is made of an elastic material. By adjusting the length of the plug-in member extending out of the connection channel, the diameter of the installation cylinder can be adjusted, and thus the storage device can be fixed on objects with different diameters or thicknesses;

[0018] 3. The installation cylinder is provided with a plurality of spring pieces in the connection channel. When the user needs to close the opening of the installation cylinder, the spring pieces can push the plug-in part entering the connection channel out of the connection channel, enabling the user to more easily operate the plug-in part to slide out of the connection channel. Accordingly, it can also ensure that after the user finishes operating the plug-in part, the plug-in part can stably abut against the installation cylinder in the clamping groove. When the user needs to open the opening of the installation cylinder, the spring pieces near the opening of the connection channel can apply pressure to the plug-in part against the side wall of the installation cylinder, making the plug-in part relatively fixed to the installation cylinder and keeping the opening of the installation cylinder open. In this state, it is more convenient to install the storage device.

[0019] 4. By providing limiting protrusions on the inner wall of the limiting clip, the limiting protrusions can slightly deform the catheter and clamp on the side wall of the catheter, preventing the catheter from displacing relative to the limiting clip and enabling the catheter to be fixed more firmly.

[0029] Embodiment 1

[0030] Refer to the attached Figures 1-5, the present application provides a nasal oxygen tube fixing device, which includes an ear hook 1 and a storage device 2. The ear hook 1 includes a hanging part 9, and the hanging part 9 is set as an arc that fits the curvature of the human ear and can be hung on the ear. A limiting clip 3 is arranged on the hanging part 9. When the hanging part 9 is hung on the ear, the limiting clip 3 is located in front of the ear, and the part of the hanging part 9 located behind the ear is longer than the part in front of the ear. This structure is easier to maintain balance. The hanging part 9 is connected to the nasal oxygen tube through the limiting clip 3. The limiting clip 3 is made of a material with good flexibility to adapt to nasal oxygen tubes of different models. When the limiting clip is connected to the nasal oxygen tube, in the natural state, the two will not displace relative to each other. Therefore, the cooperation of the limiting clip and the hanging part can fix the nasal oxygen tube on the ear. The storage device 2 includes an installation cylinder 5 with an opening on the side wall. The installation cylinder 5 is used to store the redundant catheter between the oxygen supply instrument and the human body. A plurality of limiting blocks 6 are arranged on the outer periphery of the installation cylinder 5, and a limiting opening is arranged on the side wall of the limiting block 6. The installation cylinder 5 is connected to the nasal oxygen tube through the limiting blocks 6, and the catheter can be intertwined between the plurality of limiting blocks 6. One side of the installation cylinder 5 where the opening is located is provided with a connection channel. A plurality of spring pieces 8 are arranged on one side wall of the installation cylinder 5 in the connection channel. A plug-in member 7 is slidably connected in the connection channel of the installation cylinder 5. One end of the plug-in member 7 extends out of the connection channel. When the plug-in member 7 slides into the connection channel, the opening of the installation cylinder 5 opens, and the installation cylinder 5 can be sleeved on the hospital bed railing or clamped on the patient's clothes. When the plug-in member 7 extends out of the connection channel, the opening of the installation cylinder 5 closes, and the installation cylinder 5 is fixed on an external object. Therefore, the redundant catheter between the patient and the oxygen supply instrument can be stored and fixed, and it can be prevented from being accidentally touched when the patient moves, thereby ensuring stable oxygen supply.

[0031] Preferably, a clamping groove is arranged on the side of the installation cylinder 5 away from the connection channel at the opening, and the clamping groove is set as a chamfered shape. In other embodiments, one end of the plug-in member 7 located outside the connection channel abuts against the installation cylinder 5 in the clamping groove, and the shape of the end of the plug-in member 7 abutting against the installation cylinder 5 corresponds to the shape of the clamping groove. Adopting the connection method of fitting the plug-in member 7 and the clamping groove can prevent the plug-in member 7 from being misaligned when abutting against the installation cylinder 5, resulting in the opening of the installation cylinder 5 not being able to close, and further causing the failure of fixing the installation cylinder 5 to an external object.

[0032] Preferably, the thickness of the plug-in member 7 gradually decreases from the outer end to the inner end. The plug-in member 7 is set as an ivory shape. The side of the plug-in member 7 close to the outer wall of the installation cylinder 5 gradually approaches the inner wall of the installation cylinder 5 from the outer end to the inner end. One end of the plug-in member 7 in the connection channel is set as a sharp angle shape, and the side of the plug-in member 7 close to the inner wall of the installation cylinder 5 closely adheres to the installation cylinder 5. The plug-in member 7 is designed in an ivory shape, so that the plug-in member 7 can avoid being stuck by two adjacent spring pieces 8 and cannot slide smoothly in the connection channel, and also enables the spring pieces 8 to easily push the plug-in member 7.

[0033] Preferably, the spring sheet 8 is arranged on the inner wall of the outer ring of the installation tube 5 at the connection channel, and the spring sheet 8 is inclined toward the opening of the connection channel, and the inclination direction of the spring sheet 8 is forward. The spring sheet 8 is made of elastic material, and a plurality of spring sheets 8 are set to have the same shape and size. After the plug-in 7 enters the connection channel, the spring sheet 8 close to the opening of the connection channel is subjected to the greatest pressure and the greatest degree of deformation. The spring sheet 8 exerts the smallest thrust on the plug-in 7 out of the connection channel and the greatest pressure on the side wall of the installation tube 5. The longer the part of the plug-in 7 entering the connection channel, the closer the side wall of the spring sheet 8 close to the opening of the connection channel is to the tangent to the side wall of the plug-in 7, and the smaller the thrust of the spring sheet 8 on the plug-in 7. However, at the same time, the greater the pressure of the spring sheet 8 on the plug-in 7 toward the side wall of the installation tube 5, the less likely the spring sheet 8 and the plug-in 7 will produce relative displacement, and the user can save more effort when pushing the plug-in 7 into the connection channel. When the plug-in connector 7 extends into the connection channel, the spring sheet 8 will be squeezed toward the inner wall of the outer ring of the installation tube 5 in the connection channel. During the squeezing process, the spring sheet 8 obtains the elastic force to restore the original state. Since the surface of the plug-in connector 7 in contact with the spring sheet 8 is inclined, the elastic force of the spring sheet 8 to restore the original state can be transmitted to the plug-in connector 7 and converted into a thrust to move the plug-in connector 7 out of the connection channel, thereby causing the plug-in connector 7 to slide out of the connection channel. The user can save more effort when operating the plug-in connector 7 to slide out of the connection channel. In addition, the thrust of the spring sheet 8 can also ensure that after the user finishes operating the plug-in connector 7, the plug-in connector 7 can still stably abut against the installation tube 5 in the clamping groove. The end of the spring sheet 8 is set to a pointed angle, which can reduce the contact area between the spring sheet 8 and the plug-in connector 7, thereby reducing the friction between the spring sheet 8 and the plug-in connector 7, so that the spring sheet 8 can push the plug-in connector 7 to slide out of the connection channel more smoothly.

[0034] Preferably, the installation tube 5 is provided with a sliding channel on the outer wall of the connection channel, and the sliding channel is arranged along the circumferential direction of the installation tube 5. The installation tube 5 is slidably connected with an operating member 10 in the sliding channel, and one end of the operating member 10 in the connection channel is fixedly connected to the plug-in connector 7. The plug-in connector can be driven to slide in the connection channel by toggling the operating member 10, and the portion of the spring sheet 8 at the sliding channel is cut corresponding to the shape of the sliding channel, that is, the spring sheet 8 at the sliding channel is divided into upper and lower parts, thereby preventing the spring sheet from affecting the sliding of the operating member 10 in the sliding channel.

[0035] Preferably, the installation tube 5 is made of elastic material, such as plastic, and the diameter of the installation tube 5 can be adjusted according to the length of the connector 7 extending out of the connecting channel. The longer the connector 7 extends out of the connecting channel, the larger the diameter of the installation tube 5.

[0036] Preferably, the limiting clip 3 is arranged in a C shape, and the opening of the limiting clip 3 is arranged above the limiting clip or on the side away from the hanging ear part. The height of the opening of the limiting clip 3 is smaller than the diameter of the limiting clip 3, which can more stably clamp the nasal oxygen tube in the limiting clip 3 to prevent it from falling off.

[0037] Preferably, the limiting openings are symmetrically arranged on the two side walls of the limiting block 6. The limiting openings are in a C shape, or in other embodiments, the limiting openings can also be arranged at the front section of the limiting block 6. The width of the limiting openings is smaller than the diameter of the limiting openings. A plurality of limiting blocks 6 are distributed on the side wall of the installation cylinder 5. The redundant catheter between the patient and the oxygen supply instrument can be intertwined and wound between the limiting blocks 6 for storage and fixation, preventing it from being accidentally touched when the patient moves, so as to avoid the disconnection of the nasal oxygen tube from the patient or the oxygen supply instrument, the interruption of oxygen supply, and the reduction of the treatment effect.

[0038] Working principle: When using the nasal oxygen tube, first hang the two ear hooks 1 on the two ears respectively. The limiting clip 3 is in front of the ears, and the opening of the limiting clip 3 faces upward above the ears or toward the side away from the ears. Then insert the nasal plug of the nasal oxygen tube into the nostrils, guide the catheters on both sides of the nasal plug to both sides of the ears. After adjusting to an appropriate length, clip the catheters into the limiting clip 3 for fixation. After the nasal oxygen tube on the face is fixed, guide the redundant catheter from behind the ears to the front or side of the patient's body, use the storage device 2 to store the redundant catheter, clip the catheter into the limiting opening of the limiting block 6, and wind and fix the catheter between multiple limiting blocks 6, shorten the catheter between the oxygen supply instrument and the patient to a length that can ensure the patient's movement but is not easily accidentally touched, and then fix the storage device 2 on the fence of the hospital bed or the patient's clothes to realize the storage and fixation of the redundant catheter, avoiding the long catheter being dragged when the patient moves, causing the catheter to separate from the oxygen supply instrument or slip out of the patient's nostrils, so as to ensure that the nasal oxygen tube can stably deliver oxygen to the patient and ensure the stability of the treatment effect.

[0039] Embodiment 2

[0040] Refer to the attached Figure 6 , this application provides a nasal oxygen tube fixing device. Compared with Embodiment 1, in order to more firmly clamp the catheter, a number of limiting protrusions 11 are provided on the inner wall of the limiting clip 3.

[0041] Working principle: The limiting protrusions 11 are arranged as hemispheres. The arrangement of the limiting protrusions 11 can cause the catheter made of flexible material to deform slightly and be clamped on the side wall of the catheter, so that the catheter cannot displace relative to the limiting clip 3, and the catheter can be fixed more firmly.

[0042] The above are only the specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. The protection scope of the present utility model shall be subject to the protection scope of the said claims.
