Description

Technical Field

[0001] This invention relates to the field of postoperative care equipment for nasal plastic surgery, specifically a wearable hot and cold compress device for nasal surgery. Background Technology

[0002] After rhinoplasty (such as cosmetic rhinoplasty, comprehensive nasal correction, etc.), local tissue congestion and edema caused by surgical trauma require phased hot and cold compresses to promote recovery: cold compresses within 48 hours after surgery can constrict blood vessels and reduce bleeding and swelling, while hot compresses after 48 hours can accelerate blood circulation, promote swelling reduction and tissue repair. Therefore, the standardization and effectiveness of hot and cold compresses directly affect the postoperative recovery period and results.

[0003] Current methods for applying hot and cold compresses after nasal surgery can be mainly divided into two categories: One type is traditional non-wearable hot and cold compress tools, such as ice packs, hot towels, or packaged gel media. These tools have significant drawbacks: Poor fit and irregular protruding structures in the nose (including the bridge, wings, and root of the nose) make it difficult for traditional flat tools to fit closely to the curved surface of the nose. This can lead to problems such as the hot and cold medium only acting on local areas and incomplete coverage of high-swelling areas such as the sides of the nose, resulting in uneven transfer of hot and cold energy and poor swelling reduction. Poor fixation requires patients to continuously hold and press, which not only increases hand fatigue but also makes the application position prone to shifting due to limb movement, making it impossible to maintain a stable treatment time.

[0004] Secondly, existing wearable hot and cold compress devices, although fixed through structures such as headbands and ear loops, still have shortcomings: poor adaptability, the support and compress structure are mostly fixed in size, and cannot be adjusted according to different patients' head and nose shapes, resulting in excessive gap between the compress and the nose or excessive pressure on the surgical area, affecting recovery.

[0005] Therefore, there is an urgent need for a wearable hot and cold compress device that can adapt to the nasal contour, be firmly fixed, and be easy to adjust, in order to overcome the shortcomings of existing technologies and improve postoperative recovery. Summary of the Invention

[0006] The purpose of this invention is to provide a wearable hot and cold compress device for nasal surgery, which aims to solve the problems of poor fit and need for hand-held operation of traditional non-wearable hot and cold compress tools, as well as the insufficient adaptability of existing wearable hot and cold compress devices.

[0007] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: A wearable hot and cold compress device for nasal surgery includes two earmuffs, a support, and a fixing component. The two earmuffs are respectively placed against the ears on both sides of the patient's head; the two ends of the support are rotatably connected to the outer circumference of the two earmuffs. The support includes a hoop and two support members. Each support member has a rack at the end away from the earmuff. Each end of the hoop has a receiving cavity. The inner wall of the receiving cavity has a positioning element that engages with the rack. The positioning element is reset and presses the rack in place by a spring. The racks of the two support members can extend and retract within the receiving cavities at both ends of the hoop.

[0008] A dressing bag is fixed to the side of the clamp facing the patient's nose. The dressing bag has a groove that fits the contour of the patient's nose. The dressing bag has two horizontally symmetrical reservoirs located on both sides of the groove. Each reservoir has an injection port, and the injection port is equipped with a cap for sealing the injection port. The two sides of the patient's nasal bridge fit tightly against the two side walls of the groove to transfer heat and cold through the medium in the reservoir.

[0009] A cavity is provided between the hoop and the dressing bag. The hoop has two swivel grooves at corresponding positions in each storage cavity. A ball core is connected to the swivel groove by a ball joint. The ball core has a screw hole. A bolt is threaded into the screw hole. The inner end of the bolt is placed in the cavity and abuts against the dressing bag. When the bolt is rotated in the forward direction, the bolt is screwed into the screw hole and squeezes the dressing bag. When the bolt is rotated in the reverse direction, the bolt is screwed out along the screw hole and loosens the dressing bag.

[0010] The inner end face of the bolt is equipped with an oscillator, and the outer end face has a button for turning the oscillator on and off. The button is electrically connected to the oscillator: a single press of the button turns the oscillator on, and a second press turns it off. During the process of compressing the dressing pouch with the nasal skin using the bolt, wrinkles can easily form between the pouch and the skin due to differences in nasal contours and the characteristics of the pouch material. The vibration generated by the oscillator on the inner end face of the bolt quickly smooths out these wrinkles, ensuring that the sidewalls of the pouch's groove fit tightly against the skin on both sides of the patient's nasal bridge. This guarantees that the heat or cold energy of the hot or cold medium within the reservoir can be efficiently and evenly transferred to the target area of ​​the nose, significantly improving the therapeutic effect of hot and cold compresses. The vibration generated by the oscillator can also act on the local area of ​​the nose, promoting subcutaneous blood circulation, accelerating the dissipation of postoperative bruising, and thus helping to reduce swelling.

[0011] The fixing components include an A-band, a B-band, a top headband, a back headband, and two rope retractors; one end of the A-band and one end of the B-band are respectively fixed to the outer wall of one of the earmuffs, and one end of the top headband and one end of the back headband are respectively fixed to the outer wall of the other earmuff; a foldable A-telescopic strap is connected between the free end of the A-band and the free end of the top headband, and a foldable B-telescopic strap is connected between the free end of the B-band and the free end of the back headband.

[0012] Two rope retractors are fixed to the outer sides of strap A and strap B, respectively. Pull cords are provided on the outer sides of both the headband and the back headband. The free ends of the pull cords are secured within the rope retractors. The rope retractors wind up the pull cords by rotating a knob. The structure of the rope retractors and the operation of the knobs can be referenced from existing shoelace click buckles (manufactured by Shenzhen Aikon Weida Intelligent Medical Technology Co., Ltd.). The headband is placed on the top of the patient's head, and the back headband is placed on the back of the patient's head. By rotating the knobs of the two rope retractors, the corresponding pull cords are wound up, causing the A and B elastic straps to fold and shorten, thus ensuring a secure fit of the device on the patient's head.

[0013] Compared with existing technologies, the wearable hot and cold compress device for nasal surgery that adopts the above-mentioned technical solution has the following beneficial effects: 1. Compared to traditional non-wearable hot and cold compress tools, this device features a groove on the side of the clamp facing the nose that conforms to the nose's contour, ensuring a tight fit between the sides of the nose and the sidewalls of the groove, covering all areas prone to swelling. Two horizontally symmetrical reservoirs within the compress pouch stably hold hot and cold media (such as ice water or warm water), allowing the energy to be evenly distributed along the grooves to the surgical area, avoiding localized heat concentration or omissions. This structure not only eliminates the need for the patient to hold the device, completely eliminating hand fatigue and positional misalignment, but also ensures precise application of hot and cold energy to the area requiring swelling reduction, improving efficiency and ease of use.

[0014] 2. Compared with existing wearable hot and cold compress devices, this device achieves personalized adaptation through a multi-dimensional adjustable structure: ① Adjustable support length: The receiving cavities at both ends of the clamp cooperate with the rack of the support, combined with the repositioning and pressing action of the positioning component and the spring plate, allowing for flexible extension and retraction of the support to adapt to patients with different head widths; ② Adjustable compressive fit: By increasing or decreasing the water volume in the reservoir through the injection port, the softness and hardness of the compressive pouch and the tightness of the fit to the nose can be finely adjusted; ③ Adjustable wearing tightness: Turning the cord retractor knob can retract the cord, causing the A / B telescopic straps to fold and shorten, allowing the top and back head straps to fit tightly to the top and back of the head respectively, precisely adjusting the tightness. This design can adapt to patients with different head and nose shapes, avoiding gaps or pressure between the compressive pouch and the nose, ensuring a secure fixation of the device on the head, while also considering wearing comfort, achieving personalized adaptation and comfortable wear.

[0015] 3. The earcups of this device are adjustable and can be flipped over to the same plane for storage, transforming them from a "three-dimensional protrusion" to a "flat surface," preventing direct contact between the protruding parts of the earcups and the inner wall of the packaging box. The device comes with a semi-circular dedicated packaging box whose outline perfectly matches the overall shape of the device with the earcups flat. The way the earcups are stored inside the box can be referenced from existing Dyson headphones (manufactured by Hangzhou Leyi Technology Co., Ltd.). By matching the internal space of the packaging box with the shape of the flipped earcups, no pressure contact is achieved between the earcups and the inner wall of the box. Placing the earcups flat after flipping them over completely avoids the risk of damage to the earcups due to pressure during storage, effectively protecting the structural integrity of the earcups and extending the overall durability of the device.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0027] In the embodiments of the present invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of the present invention according to the specific circumstances.

[0028] like Figures 1 to 5 The wearable hot and cold compress device for nasal surgery shown includes two earmuffs 3, a support 1, and a fixing component. The two earmuffs 3 are respectively attached to the ears on both sides of the patient's head; the two ends of the support 1 are rotatably connected to the outer periphery of the two earmuffs 3. The support 1 includes a hoop 10 and two support members 11. Each support member 11 has a rack 12 at the end away from the earmuff 3. The two ends of the hoop 10 are respectively provided with receiving cavities. The inner wall of the receiving cavity is provided with a positioning member that engages with the rack 12. The positioning member is reset and presses the rack 12 through a spring. The rack 12 of the two support members 11 can extend and retract within the receiving cavities at both ends of the hoop 10.

[0029] A dressing bag 2 is fixed to the side of the clamp 10 facing the patient's nose. The dressing bag 2 is a water bag and has a groove 20 that fits the contour of the patient's nose. The dressing bag 2 has two horizontally symmetrical storage cavities 23 located on both sides of the groove 20. Each storage cavity 23 is provided with an inlet 21 and a cap 22 for sealing the inlet 21. The two sides of the patient's nasal bridge are closely fitted with the two side walls of the groove 20 so as to transfer cold and heat through the medium in the storage cavity 23.

[0030] A cavity 15 is provided between the clamp 10 and the dressing 2. The clamp 10 has two rotating grooves at corresponding positions in each storage cavity 23. A ball core 13 is connected to each groove via a ball joint. The ball core 13 has a threaded hole, and a bolt 14 is threaded into the threaded hole. The inner end of the bolt 14 is placed in the cavity 15 and abuts against the dressing 2. When the bolt 14 is rotated forward, it screws into the threaded hole and compresses the dressing 2; when the bolt 14 is rotated in the reverse direction, it screws out of the threaded hole and releases the dressing 2. This design, through the fitting structure of the bolt 14, ball core 13, and rotating grooves at corresponding positions in the clamp 10 storage 23, allows for adjustment of the compression or release of the dressing 2 by rotating the bolt 14 in either the forward or reverse direction. By setting a cavity 15 between the clamp 10 and the dressing 2, and using a ball core 13 and threaded bolt 14 connected by a ball joint in the groove, the compression amount of the dressing 2 can be precisely adjusted by rotating the bolt 14 in both directions to adapt to the dynamic changes in the swelling of the patient's nose and individual contour differences, ensuring that the dressing 2 fits tightly to the nose to improve the efficiency of heat and cold transfer and the therapeutic effect. The ball joint structure can also adapt to the deformation of the dressing 2, avoiding damage to the dressing 2 or nasal tissue compression caused by local pressure concentration, thus improving the safety and comfort of wearing.

[0031] A vibrator 16 is provided on the inner end face of bolt 14, and a button 17 for turning the vibrator 16 on and off is provided on the outer end face of bolt 14. The button 17 is electrically connected to the vibrator 16: pressing the button 17 once triggers the vibrator 16 to turn on, and pressing the button 17 again triggers the vibrator 16 to turn off. During the process of compressing the dressing 2 with the nasal skin by the bolt 14, wrinkles are easily formed between the dressing 2 and the skin due to differences in nasal contour and the material properties of the dressing 2. The vibration generated by the vibrator 16 on the inner end face of bolt 14 after activation can quickly smooth out the wrinkles, ensuring that the sidewall of the groove 20 of the dressing 2 is in close contact with the skin on both sides of the patient's nasal bridge. This ensures that the heat or cold of the hot or cold medium in the reservoir 23 can be efficiently and evenly transferred to the target area of ​​the nose, significantly improving the therapeutic effect of hot and cold compresses. The vibration generated by the vibrator 16 can act on the local area of ​​the nose, which can promote subcutaneous blood circulation in the nose, accelerate the dissipation of postoperative bruising, and thus help reduce swelling.

[0032] The fixing components include an A-strap 31, a B-strap 32, a top headband 35, a back headband 36, and two rope retractors 33; one end of the A-strap 31 and the B-strap 32 are respectively fixed to the outer wall of one of the earmuffs 3, and one end of the top headband 35 and the back headband 36 are respectively fixed to the outer wall of the other earmuff 3; a foldable A-telescopic strap 37 is connected between the free end of the A-strap 31 and the free end of the top headband 35, and a foldable B-telescopic strap 38 is connected between the free end of the B-strap 32 and the free end of the back headband 36.

[0033] Two rope retractors 33 are fixed to the outer sides of strap A 31 and strap B 32, respectively. Pull ropes 34 are provided on the outer sides of the head strap 35 and the back head strap 36. The free ends of the pull ropes 34 are locked inside the rope retractors 33. The rope retractors 33 retract the pull ropes 34 by rotating the knob. The structure of the rope retractors 33 and the working method of the knob can refer to the existing shoelace tap-tap buckle (manufacturer: Shenzhen Aikon Weida Intelligent Medical Technology Co., Ltd.). The head strap 35 is placed on the top of the patient's head and the back head strap 36 is placed on the back of the patient's head. By rotating the knobs of the two rope retractors 33, the corresponding pull ropes 34 are retracted, which respectively drive the A telescopic strap 37 and the B telescopic strap 38 to fold and shorten, so as to achieve a secure wearing of the device on the patient's head.

[0034] Compared to traditional non-wearable hot and cold compress tools, this device features a groove 20 on the nose-facing side of the clamp 10 that conforms to the nose's contour, ensuring a tight fit between the sides of the bridge of the nose and the sidewalls of the groove 20, covering all areas prone to swelling. Two horizontally symmetrical reservoirs 23 within the compress pouch 2 stably hold hot and cold media (such as ice water or warm water), allowing the energy to be evenly distributed along the groove 20 to the surgical area, preventing localized hot or cold concentrations or omissions. This structure not only eliminates the need for the patient to hold the device, completely removing hand fatigue and positional misalignment, but also ensures precise application of hot and cold energy to the area requiring swelling reduction, improving efficiency and ease of use.

[0035] Compared to existing wearable hot and cold compress devices, this device achieves personalized fit through a multi-dimensional adjustable structure: ① Adjustable length of the support 1: The receiving cavities at both ends of the clamp 10 cooperate with the rack 12 of the support 11, combined with the repositioning and pressing action of the positioning component and the spring plate, allowing the support 11 to flexibly extend and retract to fit patients with different head widths; ② Adjustable fit of the dressing 2: By increasing or decreasing the water volume in the reservoir 23 through the inlet 21, the softness and hardness of the dressing 2 and the tightness of the fit to the nose can be finely adjusted; ③ Adjustable tightness: Rotating the knob of the rope reel 33 can reel in the rope 34, causing the A / B telescopic straps 38 to fold and shorten, so that the head strap 35 and the back head strap 36 fit tightly to the top and back of the head respectively, allowing for precise adjustment of tightness. This design can adapt to patients with different head and nose shapes, avoiding gaps or pressure between the dressing 2 and the nose, while ensuring a secure fixation of the device on the head, and also taking into account wearing comfort, achieving personalized fit and comfortable wearing.

[0036] The earcups 3 of this device are adjustable and can be flipped over to be placed on the same plane when stored. This changes the earcups 3 from a "three-dimensional protrusion" to a "flat placement," preventing the protruding parts of the earcups 3 from directly contacting the inner wall of the packaging box 4. The device is packaged in a semi-circular dedicated packaging box 4, whose outline perfectly matches the overall shape of the device after the earcups 3 are placed flat. The storage method of the earcups 3 inside the packaging box 4 can be referenced from existing Dyson headphones (manufactured by Hangzhou Leyi Technology Co., Ltd.). By matching the internal space of the packaging box 4 with the shape of the flipped earcups 3, no pressure contact is achieved between the earcups 3 and the inner wall of the packaging box 4. Placing the earcups 3 flat after flipping completely avoids the risk of damage to the earcups 3 due to pressure during storage, effectively protecting the structural integrity of the earcups 3 and extending the overall durability of the device.

[0037] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any person skilled in the art can make many possible variations and modifications to the technical solution of the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention's technical solution. Therefore, all equivalent changes made based on the shape, structure, and principle of the present invention without departing from the scope of the present invention's technical solution should be covered within the protection scope of the present invention.
