Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a headband-type tube fixator. Background Technology

[0002] In the medical field, delivering necessary substances to patients via nasogastric tubes or oxygen tubes is a common treatment method that can serve as an adjunct therapy. For some patients with severe conditions, such as those with head and neck cancer, the high doses of radiation received during treatment can cause severe symptoms such as dry mouth, loss of taste, loss of appetite, nausea and vomiting, oral (pharyngeal) mucositis, difficulty swallowing, and pain, requiring long-term nutritional supplementation through nasogastric tubes. Since nasopharyngeal carcinoma patients require face masks for fixation during radiotherapy, improper placement of the nasal catheter can affect positioning accuracy. Furthermore, in clinical practice, nasogastric tubes are often fixed to the patient's nose and face with strong elastic tape. During radiotherapy, this tape needs to be removed, and the tube placed outside the fixation mold to avoid affecting the mold's fixation and the risk of tube blockage or aspiration. Repeatedly applying and removing the tape not only increases patient discomfort but also poses risks such as facial skin damage or tube dislodgement. Therefore, a device is needed to fix the delivery tube, allowing for both secure fixation and non-invasive removal.

[0003] A Chinese patent discloses an ear-hook type tube fixator, including an ear hook, a connector, and a threaded joint. The connector is glued to the bottom of one side of the ear hook, and the connector has a threaded joint at its end. A plastic clamp is located on one side of the ear hook. This design enhances patient comfort during activity or rest, reduces the burden of the tube, and lowers the risk of accidental tube removal. After use, medical staff can disinfect the ear hook and plastic clamp with alcohol for reuse, significantly reducing operating costs. The ear-hook type tube fixator is lightweight and easy to use, designed according to human anatomy, and convenient and safe to use. It avoids skin damage caused by traditional adhesive tape and the risks associated with using sharp objects like pins. The soft material conforms closely to the earlobe, preventing pain and skin damage from prolonged wear, making it highly practical. However, this fixator cannot adjust the angle between the connector and the ear hook. The tube's angle is fixed after passing through the connector, making it impossible to adjust the direction according to the patient's face shape. This means the tube cannot fully conform to the face, posing a risk of tube bending and blockage. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a headband-type pipe fixator that can adjust the pipe direction according to the user's face to ensure that the pipe fits the user's face.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A headband-type pipe fixer includes a connecting hoop and two ear-type pipe fixers. Each ear-type pipe fixer includes an ear portion, a mounting platform, and a pipe clamping portion. The ear portion is fixedly connected to the mounting platform, and the pipe clamping portion is rotatably connected to the mounting platform. The mounting platform is also provided with a connecting portion. The end of the connecting hoop is provided with a plug-in portion, and the plug-in portion is detachably connected to the connecting portion.

[0007] With this setup, when the delivery pipe needs to be clamped, the user fixes the ear-type pipe retainer to the ear via the ear-mounted part, and then clamps and fixes the delivery pipe via the clamping part. When the user finds it inconvenient to wear it through the ear for special reasons, the ear-mounted retainer can be combined with the connecting hoop to form a headband retainer, which can be worn through the head, thus improving its applicability. The rotatable connection between the clamping part and the mounting platform also makes it easy for the user to adjust the direction of the clamping part and adjust the direction of the delivery pipe, avoiding blockage caused by pressure on the delivery pipe.

[0008] Preferably, the pipe clamping part includes a rotating disk and a pipe clamp, the mounting platform is provided with a hollow rotating platform, the rotating disk is installed inside the rotating platform and rotatably connected to the rotating platform, and the pipe clamp is installed on the rotating disk.

[0009] With this setup, users can clamp the delivery pipe with the pipe clamp and rotate the turntable to adjust the clamping direction, thereby controlling the direction of the delivery pipe and preventing it from getting tangled or knotted.

[0010] Preferably, it also includes an anti-rotation component, which includes a retaining ball and an elastic element. The rotating disk has several anti-rotation grooves on its periphery, and the rotating platform has a receiving hole. The retaining ball is elastically connected to the bottom of the receiving hole through the elastic element. The elastic element is in a compressed state, and the retaining ball also abuts against the periphery of the rotating disk.

[0011] With this configuration, the retaining bead abuts against the periphery of the rotating disk under the action of the elastic element. When the rotating disk rotates until the anti-rotation groove aligns with the receiving hole, the retaining bead is pushed out by the elastic element, and part of the retaining bead is embedded in the anti-rotation groove. The retaining bead and the two sides of the anti-rotation groove form a limit, increasing the resistance that the rotating disk needs to overcome to rotate. When further rotation adjustment is needed, the user rotates the rotating disk with greater force. The contact point between the retaining bead and the anti-rotation groove is an arc-shaped structure, so the retaining bead is pressed back into the receiving hole by the force until it rotates into another anti-rotation groove. The retaining bead then pops out again to stop rotation, thus forming a staged rotation adjustment. This avoids the rotating disk being easily affected by external interference after the angle is adjusted, thereby improving the limiting effect on the delivery pipe.

[0012] Preferably, the pipe clamp includes a clamping platform and a cover plate. The clamping platform is provided with a clamping groove, and the cover plate is installed on the side of the clamping groove. One side of the cover plate is rotatably connected to the clamping platform, and the other side of the cover plate is detachably connected to the clamping platform.

[0013] With this setup, the user can first rotate to open the cover plate and place the delivery pipe in the clamping groove, then close the cover plate and connect it to the clamping platform, thereby ensuring that the delivery pipe is confined within the clamping groove.

[0014] Preferably, the hanging ear is an arc-shaped hook structure, and the hanging ear is fixedly connected to the side of the mounting platform.

[0015] With this design, users can hang the ear loops on the earlobe for easy wearing or removal.

[0016] Preferably, the end of the ear loop is also provided with a rounded corner structure.

[0017] This design prevents the ear loops from being too sharp and scratching the user, thus improving user comfort.

[0018] Preferably, the inner side of the ear loop is provided with a buffer layer, which is made of a flexible material.

[0019] This design allows the cushioning layer to absorb pressure on the earlobe, improving user comfort during extended wear.

[0020] Preferably, the plug portion has snap-fit ​​protrusions on both sides, the angle between the snap-fit ​​protrusions and the plug portion is less than 90°, the snap-fit ​​protrusions are made of elastic material, the connecting portion has a plug hole corresponding to the plug portion, and the plug hole has an opening corresponding to the snap-fit ​​protrusion.

[0021] With this design, when the plug is inserted into the socket of the connector, the snap-fit ​​protrusion will pop out through the opening. The snap-fit ​​protrusion and the opening form a limit to prevent the plug from falling out of the socket. When it is necessary to disassemble the ear-type tube retainer, the user presses the snap-fit ​​protrusion to retract into the opening, and then pulls the plug out of the socket to complete the separation.

[0022] Preferably, the connecting hoop includes a connecting section and two movable sections. The connecting section has sliding holes at both ends, and the movable sections are provided with sliding strips. The sliding strips of the two movable sections are slidably inserted into the sliding holes at both ends of the connecting section, and the insertion part is fixedly connected to the end of the movable section away from the connecting section.

[0023] With this setting, users can adjust the size of the connecting clamp according to their own head size. The length of the connecting clamp can be controlled by pulling out or inserting the slider, which is beneficial for adapting to different head sizes and improving the applicability of the head clamp tube fixator.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] (1) The clamping part is rotatably connected to the mounting platform, which makes it easy for the user to adjust the direction of the clamping part according to the face shape, thereby ensuring that the delivery pipe fits tightly with the face, which helps to reduce the probability of pipe bending and blockage, and improves the safety of use.

[0026] (2) The ear loops make it easy for users to put on or take off the fixation device without causing damage to the skin. The adjustable clamps make it easy to adjust the position and direction of the delivery tube, which improves its practicality.

[0027] (3) By setting the anti-rotation component, the user can adjust the direction of the pipe clamp by rotating the disc, and the disc is prevented from rotating again after the adjustment is completed, thus improving the fixing effect of the delivery pipe.

[0028] (4) By setting the connecting hoop, the ear-hook tube fixator can be combined into a headband tube fixator, which has multiple wearing methods and can be adjusted according to the patient's condition, thus improving the scope of application. Attached Figure Description

[0037] Example 1

[0038] like Figures 4 to 6 The illustration shows an embodiment of a headband-type pipe fixator, which includes a connecting hoop 5 and two ear-type pipe fixators. The ear-type pipe fixator includes an ear part 1, a mounting platform 2, and a pipe clamping part 3. The ear part 1 is fixedly connected to the mounting platform 2, and the pipe clamping part 3 is rotatably connected to the mounting platform 2. The mounting platform 2 is also provided with a connecting part 23. The end of the connecting hoop 5 is provided with a plug-in part 51, and the plug-in part 51 is detachably connected to the connecting part 23.

[0039] With this design, when a user finds it inconvenient to wear the device through their ears for special reasons, the ear-hook fixator and the connecting band 5 can be combined into a headband fixator for wearing through the head, which helps to improve the applicability.

[0040] With this setup, when it is necessary to clamp the delivery pipe, the user fixes the ear-type pipe holder to the ear through the ear part 1, and then clamps and fixes the delivery pipe through the clamping part 3. The clamping part 3 is rotatably connected to the mounting platform 2, which also makes it easy for the user to adjust the direction of the clamping part 3 and adjust the direction of the delivery pipe to avoid blockage caused by pressure on the delivery pipe.

[0041] As one embodiment of the present invention, the pipe clamping part 3 includes a rotating disk 31 and a pipe clamp 32. The mounting platform 2 is provided with a hollow rotating platform 21. The rotating disk 31 is installed inside the rotating platform 21 and is rotatably connected to the rotating platform 21. The pipe clamp 32 is installed on the rotating disk 31.

[0042] With this setup, the user can clamp the delivery pipe with the pipe clamp 32 and rotate the rotating disk 31 to adjust the clamping direction of the pipe clamp 32, thereby controlling the direction of the delivery pipe and preventing the delivery pipe from getting tangled or knotted.

[0043] As one embodiment of this utility model, it also includes an anti-rotation component 4, which includes a retaining bead 41 and an elastic element 42. A plurality of anti-rotation grooves 311 are provided on the periphery of the rotating disk 31, and a receiving hole 22 is provided in the rotating table 21. The retaining bead 41 is elastically connected to the bottom of the receiving hole 22 through the elastic element 42. The elastic element 42 is in a compressed state, and the retaining bead 41 also abuts against the periphery of the rotating disk 31.

[0044] With this configuration, the retaining bead 41 abuts against the periphery of the rotating disk 31 under the action of the elastic element 42. When the rotating disk 31 rotates until the anti-rotation groove 311 aligns with the receiving hole 22, the retaining bead 41 is pushed out by the elastic element 42, and part of the retaining bead 41 is embedded in the anti-rotation groove 311. The retaining bead 41 and the two sides of the anti-rotation groove 311 form a limit, increasing the resistance that the rotating disk 31 needs to overcome to rotate. When further rotation adjustment is required, the user rotates the rotating disk 31 with greater force. The contact point between the retaining bead 41 and the anti-rotation groove 311 is an arc-shaped structure, so the retaining bead 41 will be pressed back into the receiving hole 22 under force until it rotates into another anti-rotation groove 311. The retaining bead 41 then pops out again to stop rotation, thus forming a staged rotation adjustment. This avoids the rotating disk 31 being easily affected by external interference after the angle is adjusted, thereby improving the limiting effect on the conveying pipe.

[0045] As one embodiment of the present invention, the pipe clamp 32 includes a clamping platform 321 and a cover plate 322. The clamping platform 321 is provided with a clamping groove 323. The cover plate 322 is installed on the side of the clamping groove 323. One side of the cover plate 322 is rotatably connected to the clamping platform 321, and the other side of the cover plate 322 is detachably connected to the clamping platform 321.

[0046] With this setup, the user can first rotate and open the cover plate 322, install the conveying pipe in the clamping groove 323, then close the cover plate 322 and connect the cover plate 322 to the clamping platform 321, thereby ensuring that the conveying pipe is confined within the clamping groove 323.

[0047] Example 2

[0048] The following is a second embodiment of the ear-type tube fixer of this utility model. This embodiment is similar to the first embodiment, except that the ear part 1 is further defined.

[0049] As one embodiment of this utility model, the ear part 1 is an arc-shaped hook structure, and the ear part 1 is fixedly connected to the side of the mounting platform 2.

[0050] With this setup, users can hang the ear loop 1 on the earlobe for easy wearing or removal.

[0051] As one embodiment of this utility model, the end of the ear part 1 is also provided with a rounded corner structure.

[0052] This design avoids the end of the ear loop 1 from scratching the user due to being too sharp, thus improving user comfort.

[0053] As one embodiment of this utility model, a buffer layer 11 is provided on the inner side of the ear loop 1, and the buffer layer 11 is made of flexible material.

[0054] With this design, the buffer layer 11 can cushion the pressure on the auricle, improving the user's comfort during long-term wear.

The mounting platform 2 is also provided with a connecting part 23. The end of the connecting hoop 5 is provided with a plug-in part 51, and the plug-in part 51 is detachably connected to the connecting part 23.

[0057] With this design, when a user finds it inconvenient to wear the device through their ears for special reasons, the ear-hook fixator and the connecting band 5 can be combined into a headband fixator for wearing through the head, which helps to improve the applicability.

[0058] As one embodiment of the present invention, the plug-in part 51 is provided with snap-fit ​​protrusions 511 on both sides, the included angle between the snap-fit ​​protrusions 511 and the plug-in part 51 is less than 90°, the snap-fit ​​protrusions 511 are made of elastic material, the connecting part 23 is provided with a plug hole 231 corresponding to the plug-in part 51, and the plug hole 231 is provided with an opening corresponding to the snap-fit ​​protrusions 511.

[0059] With this configuration, when the plug part 51 is inserted into the socket 231 of the connector 23, the snap-fit ​​protrusion 511 will pop out through the opening. The snap-fit ​​protrusion 511 and the opening form a limit to prevent the plug part 51 from falling out of the socket 231. When it is necessary to disassemble the ear-type tube retainer, the user presses the snap-fit ​​protrusion 511 to retract it into the opening, and then pulls the plug part 51 out of the socket 231 to complete the separation.

[0060] As one embodiment of the present invention, the connecting hoop 5 includes a connecting section 52 and two movable sections 53. Both ends of the connecting section 52 are provided with sliding holes, and the movable sections 53 are provided with sliding strips 531.
