[0033] The embodiments of the present utility model are described below in conjunction with the accompanying drawings.

[0034] like Figure 1-Figure 3 As shown, the utility model proposes a nasal high-flow oxygen tube fixing device, including a fixing mechanism 10, a winding mechanism 20, a limiting mechanism 30 and a connecting tape 40; wherein the fixing mechanism 10 is provided with a fixing clamp 11 to clamp the oxygen tube so that the oxygen tube is fixed under the patient's nose; the winding mechanism 20 is provided with a storage rod 23 for winding up the restraining belt 22, the storage rod 23 is rotatably arranged in a storage box 21, and the restraining belt 22 passes through the storage box 21 and is connected to the fixing mechanism 10; the limiting mechanism 30 is arranged in the storage box 21, and is movably connected to the storage rod 23, and is used to limit the movement and rotation of the storage rod 23; the connecting tape 40 is provided with a matching buckle 41 and a clamping hole 42; the connecting tape 40, the fixing mechanism 10 and the winding mechanism 20 form an enclosed whole for being sleeved on the patient's head.

[0035] In the present application, the storage box 21 is used to fix the storage rod 23, and is provided with a cavity for accommodating the restraining belt 22 and the limiting mechanism 30. Its specific structure can be a rectangular parallelepiped or a cylinder or other shapes, which is not limited here; when the storage rod 23 rotates in the storage box 21, the restraining belt 22 can be rolled up or released, so that the overall device can be extended or shortened to suit different patients; at the same time, the limiting mechanism 30 is movably connected to the storage rod 23, and the movement and rotation of the storage rod 23 can be controlled by adjusting the limiting mechanism 30 according to the use requirements; by engaging the buckle 41 and the buckle hole 42 of the connecting tape 40, the fixing mechanism 10, the winding mechanism 20 and the connecting tape 40 can be connected to form an enclosed annular whole, which is mounted on the patient's head, thereby achieving a stable fixation of the oxygen inhalation tube.

[0036] In a specific embodiment, the nasal high-flow oxygen inhalation tube fixing device in the present application is provided with two reeling mechanisms 20, which are respectively arranged at the two ends of the fixing mechanism 10 and are respectively connected to the connecting cassette 40;

[0037] In other embodiments of the present application, the number of the winding mechanism 20 is set to one according to demand; one end of the winding mechanism 20 is connected to the fixing mechanism 10 , and the other end is connected to the connecting tape 40 , and the other end of the connecting tape 40 is directly connected to the fixing mechanism 10 .

[0038] In a specific embodiment, Figure 1-Figure 2 As shown, the present application proposes a specific structure that can realize the winding function of the winding mechanism 20: the storage box 21 is provided with a hole, one end of the storage rod 23 passes through the hole and is provided with a hand crank 231; the middle part of the storage rod 23 is provided with a winding portion 232, and the restraint belt 22 is wound around the winding portion 232. By rotating the hand crank 231, the storage rod 23 can be rotated around its axis, thereby driving the restraint belt 22 to be wound around the winding portion 232 or extending outward from the winding portion 232, thereby controlling the length of the restraint belt 22 extending outside the storage box 21.

[0039] In this embodiment, the winding portion 232 includes two clamping plates relatively arranged in the middle of the storage rod 23, and the distance between the two clamping plates is slightly larger than the width of the restraining belt 22, so as to limit the restraining belt 22 from deviating to both sides during the winding or releasing process, causing it to be stuck between the storage rod 23 and the storage box 21, affecting the normal use of the winding mechanism 20.

[0040] Furthermore, a plurality of insertion holes 233 are circumferentially arranged at one end of the storage rod 23 close to the hole, and the insertion rod 31 of the limiting mechanism 30 is movably inserted in the insertion hole 233; specifically, when the insertion rod 31 is inserted in the insertion hole 233, the storage rod 23 is restricted to a fixed position of the storage box 21, and at this time, it can neither move toward the direction of the hole nor rotate, thereby preventing the storage rod 23 from rotating during use and improving the stability of the storage rod 23.

[0041] In this embodiment, in order to achieve fine adjustment of the length of the restraint belt 22 , a plurality of insertion holes 233 are densely arranged around the storage rod 23 , and the distance between the centers of two insertion holes 233 is the minimum adjustment length of the restraint belt 22 .

[0042] In a specific embodiment, the hand crank 231 is provided with a snap-fitting portion whose shape is larger than the hole of the storage box 21. The snap-fitting portion of the hand crank 231 fits against the inner side of the storage box 21. At this time, the insertion hole 233 of the storage rod 23 can just be in a relative position with the insertion rod 31 of the limiting mechanism 30, so that the insertion rod 31 can enter and exit the insertion hole 233.

[0043] Furthermore, if Figure 2 As shown, the limiting mechanism 30 also includes a first elastic member 32, which is fixed to the inner wall of the storage box 21 and connected to the insertion rod 31 through a sliding member 33; the sliding member 33 is provided with a pull rod 34, which is parallel to the first elastic member 32 and passes through the inner wall of the storage box 21. In the present application, the insertion rod 31 is vertically inserted into the insertion hole 233, and the corresponding first elastic member 32 is arranged in a direction perpendicular to the storage rod 23. One end of the elastic member 32 is arranged on the inner wall of the storage box 21 corresponding to the position of the insertion hole 233, and the other end is connected to the sliding member 33. The sliding member 33 is also provided with a pull rod 34 parallel to the first elastic member 32, and the other end of the pull rod 34 passes through the storage box 21. The inner wall; when in use, the first elastic member 32 is always in a compressed state, so that the insertion rod 31 can be inserted into the socket 233 under sufficient pressure, thereby limiting the movement or rotation of the storage rod 23; when the storage rod 23 needs to be rotated, the pull rod 34 is pulled outward to drive the sliding member 33 to move away from the socket 233, thereby driving the insertion rod 31 to disengage from the socket 233 to release the restriction on the storage rod 23, and then the hand crank 231 is turned to rotate the storage rod 23. When the required length of the restraint belt 22 is adjusted, the pull rod 34 is released. At this time, the sliding member 33 is reset under the action of the pressure of the first elastic member 32, and the insertion rod 31 is inserted into the socket 233 to achieve the limitation of the storage rod 23.

[0044] Furthermore, a guide rod 35 is also provided in the storage box 21. The guide rod 35 is parallel to the pull rod 34 and is slidably connected to the sliding member 33. By providing the guide rod 35 to cooperate with the pull rod 34, the moving direction of the sliding member 33 is further limited to prevent it from becoming unstable during the process of reciprocating insertion and disengagement from the socket 233, affecting the limiting of the storage rod 23, and further improving the stability of the limiting mechanism 30.

[0045] In this embodiment, the guide rod 35 is arranged on the inner wall of the same plane as the hole, and is slidably connected to the first end of the sliding member 33. The pull rod 34 is arranged at the second end of the sliding member 33. The first end and the second end are opposite ends of the sliding member 33. The first elastic member 32 is arranged between the pull rod 34 and the guide rod 35, and the three are arranged in parallel; that is, the guide rod 35 and the pull rod 34 limit the sliding member 33 from the opposite ends of the sliding member 33, so that it can only move back and forth in a direction perpendicular to the storage rod 23, so that the insertion rod 31 can stably and effectively perform its limiting function.

[0046] Furthermore, if Figure 2 As shown, the storage box 21 in this embodiment is also provided with a slot 211, and the other end of the storage rod 23 is inserted into the slot 211. The shape of the slot 211 matches the shape of the storage rod 23, so that the end of the storage rod 23 will not easily escape from the slot 211; at this time, the two ends of the storage rod 23 are limited by the holes and the slot 211 respectively, even in the process of rotating the storage rod 23, the storage rod 23 can stably rotate around its axis without deviation; at the same time, when the patient uses it, the storage rod 23 is limited by the holes, the slot 211 and the insertion rod 31, and will not move, ensuring that the storage rod 23 is in a stationary state during use, and the overall device can be stably fixed on the patient's head.

[0047] In another preferred embodiment, the storage box 21 is provided with a bearing, and the other end of the storage rod 23 is connected to the bearing. At this time, the two ends of the storage rod 23 are limited by holes and bearings respectively. On the one hand, the bearing enables the storage rod 23 to better rotate around its axis in the storage box 21. On the other hand, the connection between the bearing and the storage rod 23 can further prevent the storage rod 23 from moving to the outside of the hole, thereby playing a better limiting role and further ensuring the stability of the storage rod 23 during rotation.

[0048] Furthermore, if Figure 3 As shown, the fixing clamp 11 is provided with a through hole for accommodating the oxygen absorption tube, and a clamping piece 111 is movably arranged in the through hole to clamp the oxygen absorption tube; specifically, connecting tubes 12 are provided at both ends of the fixing clamp 11, and the clamping piece 111 passes through the side wall of the through hole and is connected to the second elastic piece 121 in the connecting tube 12, and the second elastic piece 121 is always in a compressed state, with sufficient pressure to make the clamping piece 111 pass through the side wall of the through hole into the through hole and clamp the oxygen absorption tube in the through hole, but at the same time will not affect the flow of oxygen in the oxygen absorption tube; in this embodiment, the surface of the clamping piece 111 in contact with the oxygen absorption tube is provided with anti-slip material to increase the friction between the clamping piece 111 and the oxygen absorption tube to prevent the oxygen absorption tube from falling out; when the oxygen absorption tube needs to be installed in the fixing clamp 11 or removed from the fixing clamp 11, it is only necessary to move the clamping piece 111 by hand or with a tool to retract it into the connecting tube 12.

[0049] In this embodiment, in order to further limit the moving direction of the clamping member 111, a clamping plate is provided between the clamping member 111 and the second elastic member 121. The size of the clamping plate matches the inner wall of the connecting tube 12 to prevent the clamping member 111 from deflecting during movement.

[0050] In a preferred embodiment, in order to make the overall structure of the fixing mechanism 10 more stable, the fixing mechanism 10 also includes a fixing frame 13, and the connecting tube 12 and the fixing clip 11 are both arranged in the fixing frame 13. On the one hand, the fixing frame 13 is connected to the connecting tube 12 to form a whole, and on the other hand, it can provide protection for the connecting tube 12 and the fixing clip 11 to prevent them from being damaged by external factors during use; preferably, in order to be more convenient to use, the fixing frame 13 includes a rubber plate 131, which can better fit the human body.

[0051] The fixing frame 13 in the present application may be composed of a plurality of plate-like components or rod-like components or a combination of the two, which is not limited here.

[0052] In this embodiment, the fixing frame 13 includes two connecting plates 132 and a rubber plate 131 . The two connecting plates 132 are disposed at opposite ends of the rubber plate 131 . The two connecting tubes 12 are connected to the two connecting plates 132 , respectively.

[0053] In order to further increase the convenience of using the device and reduce its volume, the connecting tube 12 and the restraining belt 22 in this embodiment extend in the same direction, and the restraining belt 22 and the connecting tube 12 are respectively arranged on both sides of the connecting plate 132 .

[0054] In other embodiments of the present application, only one end of the fixing clip 11 is provided with a connecting tube 12 .

[0055] When using the device, the user first places the rubber plate 131 above the patient's lips, and then pulls the pull rod 34 outward, and pulls the sliding member 33 to move through the pull rod 34, thereby compressing the first elastic member 32 and driving the insertion rod 31 to move in the direction away from the storage rod 23. When the insertion rod 31 is out of the insertion hole 233, the limiting pressure of the storage rod 23 is eliminated. Then the user holds the hand crank 231, and drives the storage rod 23 to rotate by turning the hand crank 231, and unwinds the restraint belt 22 through the storage rod 23. The user can adjust the length of the restraint belt 22 according to the size of the patient's head; after the adjustment is completed, release the finger that pulls the pull rod 34, and the first elastic member 32 is compressed, and the first elastic member 32 is compressed, and the second ... An elastic member 32 pushes the sliding member 33 to move toward the direction of the storage rod 23, thereby driving the insertion rod 31 to move and insert into the insertion hole 233, thereby completing the limiting fixation of the storage rod 23; then the user wraps the restraint belt 22 around the back or side of the patient's head, inserts the buckle 41 into the clamping hole 42, so that the rubber plate 131 is firmly fixed above the patient's lips, and then uses a tool to move the clamp 111 to move the clamp 111 toward the inside of the connecting tube 12. When there is enough space in the through hole of the fixing clip 11, the oxygen tube is inserted into the through hole, and then the tool is removed. The second elastic member 121 pushes the clamp plate to move, thereby driving the clamp 111 to reset and clamp the oxygen tube.

[0056] The utility model can effectively adjust the length of the restraining belt by providing the storage rod and the storage box, so as to be suitable for different patients and improve the comfort of the patients in using the oxygen tube; by providing the limiting mechanism, the movement and rotation of the storage rod can be restricted, and the stability of the winding mechanism is improved; by the cooperation of the fixing clip, the clamping piece and the connecting tube, the oxygen tube can be more conveniently fixed to the fixing clip, and the use efficiency of the fixing clip is improved; the utility model is easy to operate and control during use and has good reliability.

[0057] The above is a detailed description of the embodiments of the utility model, but the contents are only preferred embodiments of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
