Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a headband-type adjustable compression bandage for parotid gland surgery. Background Technology

[0002] Following surgery for oral and maxillofacial tumors, trauma, or infection, especially surgeries involving the parotid gland area, effective postoperative local pressure bandaging is a crucial step. Its main purposes are to prevent postoperative wound cavity effusion or hematoma formation, reduce dead space, promote tissue adhesion and healing, and simultaneously suppress parotid gland secretion through moderate compression, reducing the risk of complications such as salivary fistula. Therefore, stable, uniform, and sustainable postoperative compression has irreplaceable clinical value in ensuring surgical outcomes and promoting patient recovery.

[0003] Currently, the traditional "cross-bandage" pressure dressing method is commonly used in clinical practice for compression of the parotid gland postoperative area. This method mainly relies on covering the wound with multiple layers of gauze dressings and then using a bandage wrapped in a specific cross-shaped pattern to strongly fix and compress the patient's head and maxillofacial region. However, this traditional method has several inherent drawbacks: First, it requires a high level of professional expertise. The tightness of the bandage and the distribution of pressure largely depend on the individual experience and skill of the medical staff, making it difficult to standardize and quantify, and easily leading to uneven pressure and displacement of the compression point. Second, it results in poor patient comfort and numerous complications. Tight bandages often cause pain in the ear and temporal region, skin pressure injuries, and severely hinder mouth opening, chewing, swallowing, and speech functions, affecting early postoperative eating and communication, and increasing patient suffering and anxiety. Third, the effect is unstable. Due to facial movement, changes in swelling, and the bandage itself loosening, the pressure is difficult to maintain consistently, often requiring frequent re-bandaging, increasing the workload of medical staff and the consumption of dressings. Fourth, adjustment and observation are inconvenient. Each time the wound is checked or the pressure is adjusted, the bandage must be completely unwrapped and re-bandaged, which is a cumbersome process and makes it impossible to fine-tune the pressure position or dynamically adapt the pressure.

[0004] Therefore, there is an urgent clinical need for a specialized compression device for parotid gland surgery that can achieve precise positioning, controllable pressure, comfortable wear, easy adjustment and observation, and adapt to the dynamic recovery needs after surgery, in order to make up for the shortcomings of existing technologies and improve the quality and efficiency of postoperative care. Summary of the Invention

[0005] In order to solve the problems of the prior art, the present invention provides a headband-type adjustable compression bandage for parotid gland surgery.

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: a headband-type adjustable compression bandage after parotid gland surgery, including a U-shaped headband, wherein a limiting groove is provided on the outer side of the U-shaped headband, and a plurality of positioning holes are provided inside the limiting groove. The U-shaped headband is configured as an elastic element, which generates a compression force through the amount of twisting for stable wearing. The outer side of the U-shaped headband is slidably connected to a compression accessory, which is composed of a limiting sliding member and an accessory base plate. The limiting sliding member is provided with a positioning mechanism to fix the compression accessory and the U-shaped headband together. The side of the accessory base plate facing the face is detachably provided with a contact pad or an adjusting air cushion. An accessory fabric retainer is sleeved on one outer wall of the accessory base plate. The accessory fabric retainer is used to clamp and fix the medical gauze between the accessory fabric retainer and the accessory base plate.

[0007] In one specific embodiment, a soft pad is provided on the inner side of the U-shaped headband to buffer pressure.

[0008] In one specific embodiment, the number of the limiting grooves is set to two, and the two limiting grooves are respectively distributed at both ends of the U-shaped headband.

[0009] In one specific embodiment, the positioning mechanism includes a threaded rod, a slider, a slide bar, and a positioning block; The threaded rod is rotatably connected to the inside of the limiting sliding member via a bearing. The outer wall of the slider is slidably connected to the inner wall of the limiting sliding groove. The slider has a sliding groove inside, and a sliding rod is slidably connected inside the sliding groove. The sliding rod and the threaded rod are connected by a threaded sleeve. One end of the sliding rod is fixedly connected to the positioning block. The outer wall of the positioning block matches the inner wall size of the positioning hole.

[0010] In one specific embodiment, a locking hole is provided on one side of the auxiliary material base plate, and a locking block is provided on one side of the contact pad. The outer wall size of the locking block matches the inner wall size of the locking hole, and the cross-sectional size of the opening of the locking hole is smaller than the cross-sectional size of the maximum size of the locking block, which is used to fix the locking block.

[0011] In one specific embodiment, a locking block is provided on one side of the adjusting air cushion, and the adjusting air cushion is detached and fixed to the auxiliary material base plate through the locking block. An air valve is provided on one side of the adjusting air cushion for inflating or deflating. The adjustable air cushion is made of medical-grade silicone or rubber and has elastic deformation capability.

[0012] In one specific embodiment, the contact pad and the adjusting air cushion are configured as disposable medical products.

[0013] In one specific embodiment, the limiting slide groove is provided with a position marking line to guide the pressing auxiliary part to slide to a predetermined position for fixing.

[0014] In one specific embodiment, the top two sides of the U-shaped headband are provided with arc-shaped widening portions, which are used to increase the contact area with the head and provide anti-slip positioning.

[0015] The beneficial effects of this invention are as follows: 1. The adjustable compression bandage provided by this invention, compared to the traditional cross-bandage fixation method, firstly achieves precise, personalized, and dynamically adjustable compression therapy. Through a unique U-shaped headband and a modular design with a sliding locking compression component, medical staff can precisely align the compression point with the postoperative target area along the slide rail, and utilize mechanical positioning or airbag pressure adjustment mechanisms to achieve quantitative control and real-time fine-tuning of the compression force. This solves the drawbacks of traditional methods, such as fixed compression position, uneven pressure, and inability to precisely control it. It also allows the compression force to be adaptively adjusted according to the needs of different postoperative stages (such as initial hemostasis and later swelling reduction). Simultaneously, the quickly replaceable functional contact pads (such as constant pressure air cushions and cold compresses) further expand its therapeutic functions, enabling a single device to meet the needs of diverse clinical scenarios. 2. This device optimizes the patient's treatment experience and clinical procedures, and improves treatment safety and hygiene standards. Its earphone-style headband structure and elastic, breathable material significantly reduce discomfort and stuffiness in the ears and jaw caused by traditional tight bandages, allowing patients to eat and talk normally, significantly reducing their psychological burden and improving treatment compliance. For medical staff, the intuitive sliding rail positioning, clear adjustment mechanism, and modular assembly make operation simple and quick, reducing reliance on special bandaging techniques and improving work efficiency. Regarding infection control, by strictly separating the sterilizable and reusable substrate from disposable sterile contact parts, the cleanliness of materials in direct contact with the wound is ensured, effectively avoiding the risk of cross-infection and meeting the high safety standards of modern medicine.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0023] like Figures 1 to 5 The headband shown is an adjustable compression bandage after parotid gland surgery.

[0024] I. Fabrication and Assembly Process of the Device The production of this device follows the medical device quality management standards and adopts a modular design, which facilitates standardized manufacturing and assembly.

[0025] Manufacturing of U-shaped headband 1: Material selection: The U-shaped headband is made of highly elastic, hypoallergenic medical-grade nylon blended elastic fabric, which has good breathability, stretch, and durability. A layer of skin-friendly soft fleece can be laminated on the inside to enhance comfort.

[0026] Structural Forming: The fabric is cut into strips of predetermined length using ultrasonic cutting or laser cutting. On its outer side, along the length direction, two parallel limiting grooves 11 made of medical-grade polymer plastic (such as POM or PP) are embedded using high-frequency hot pressing or sewing. The inner side is smooth. At predetermined positions on the grooves, a series of positioning holes 12 are stamped or laser-engraved using precision molds.

[0027] The U-shaped headband 1 corresponds to the area of ​​the wearer's temples (near the temples) and above the ear. Ergonomic optimization can be achieved by locally thickening the headband or using memory foam pads to reduce the feeling of pressure.

[0028] The position marking line 13 facilitates the rapid initial positioning of the subsequent pressing auxiliary parts.

[0029] Assembly of the pressure auxiliary component 2: Processing of the limiting sliding component 21: The sliding housing is manufactured by injection molding using medical-grade engineering plastics (such as ABS or PC) to match the shape of the limiting sliding groove 11. An internal mounting cavity is reserved.

[0030] Positioning mechanism assembly: The slide rod 214 is passed through the central through hole of the slide groove 213. The threaded rod 211 is mounted inside the sliding housing via a miniature bearing and engages with the threaded hole in the middle of the slide rod 214. The positioning block 215 is fixed to one end of the slide rod, and its shape complements the positioning hole 12 for positioning. Finally, the assembly with the slider 212 is installed into the housing, so that the slider 212 engages with the track of the limiting slide groove 11. Rotating the knob (connecting the threaded rod) tests whether the positioning block 215 can smoothly extend / retract and engage with the positioning hole 12.

[0031] The base plate 22 is molded using medical-grade plastic injection molding, and is in the shape of a disc or an elliptical disc. One side has an interface (such as a snap-fit ​​or screw hole) for fixing to the limiting sliding member 21, and the other side has a locking hole 222 at its center. An annular groove is designed on the outer edge to accommodate the auxiliary fabric retaining ring 221. The auxiliary fabric retaining ring 221 is an elastic open ring and can be made of plastic.

[0032] Contact preparation: Contact pad 223: A sterile, individually packaged, disposable medical material, such as a silicone pad, hydrogel dressing, or foam dressing. A locking block 2231 is molded onto its back side to interfere with the locking hole 222.

[0033] Adjustable air cushion 224: Made of medical-grade TPU film through high-frequency heat sealing to form a sealed airbag, with a locking block 2231 on the back. The airbag integrates a miniature one-way air intake valve and a manually pressable deflation button, forming an air valve.

[0034] Assembly: Securely connect the assembled limiting sliding component 21 to the auxiliary material base plate 22. Fit the auxiliary material fabric retaining ring 221 onto the groove of the base plate.

[0035] Final assembly and initial inspection: The assembled compression auxiliary component 2 is slid into the limiting groove 11 from one end of the U-shaped headband 1 via its slider 212.

[0036] Check whether the pressure accessories can slide smoothly, whether the positioning mechanism works reliably, and whether the Velcro is firmly attached.

[0037] Remove location marker line 13.

[0038] II. Disinfection and Sterilization Treatment This device employs a graded disinfection and sterilization strategy based on the degree of contact with the patient: The U-shaped headband 1 and the base of the compression accessories (limiting sliding part 21, accessory base plate 22, accessory fabric retaining ring 221): As reusable components, they are sterilized with ethylene oxide (EO) before leaving the factory. After clinical use, they can be sterilized by low-temperature plasma sterilization or soaked or wiped with qualified medical disinfectants (such as chlorine-containing disinfectant or alcohol). After disinfection, they must be rinsed with sterile water and air-dried. All materials are resistant to common disinfection methods.

[0039] Contact pad 223 and adjusting air cushion 224: As disposable sterile components, each is individually sealed in a medical dialysis paper / plastic composite bag. Before leaving the factory, they undergo final sterilization using irradiation (such as cobalt-60 gamma rays) or ethylene oxide to ensure sterility. The packaging bag is printed with the product batch number, expiration date, and sterilization symbol. Use immediately after opening; dispose of as medical waste after use.

[0040] Medical gauze: As the first layer of dressing to absorb exudate, standard sterile gauze is prepared by the user and fixed by the auxiliary fabric clip 221.

[0041] III. Usage Methods and Operating Procedures Preoperative preparation: Medical staff selected the appropriate U-shaped headband size 1 based on the patient's head circumference.

[0042] Check that reusable parts have been cleaned and sterilized. Remove the disposable contact pad 223 or adjusting air cushion 224 from the aseptic packaging.

[0043] Intraoperative procedures (taking the use of a contact pad as an example): Apply the base dressing: Cover the surgical wound after parotid gland surgery with an appropriate amount of sterile gauze.

[0044] Wearing the bandage: Wrap the U-shaped headband 1 around the patient's head, so that the pre-set compression accessory 2 is roughly located in the affected cheek area. Use the first Velcro 14 and the second Velcro 15 at both ends for initial fixation, with the tightness being stable and comfortable.

[0045] Precisely locate the compression point: Loosen the positioning mechanism of the compression adjuvant 2 (rotate the knob counterclockwise to retract the positioning block 215). Gently slide the compression adjuvant along the limiting groove 11 until the center of the adjuvant base plate 22 is aligned with the core position of the parotid gland area that needs to be compressed after surgery.

[0046] Locking position: Rotate the knob clockwise to drive the positioning block 215 to extend and insert into the nearest positioning hole 12 to achieve a secure lock.

[0047] Install the contact pad: Align the clip 2231 on the back of the selected sterile contact pad 223 with the clip hole 222 on the auxiliary material base plate 22, and press it down firmly until it clicks into place.

[0048] Secure the outer gauze: Cover the contact pad with another piece of sterile gauze and use the gauze clip 221 to tightly press its edges into the groove of the gauze base plate 22.

[0049] Fine-tuning the pressure: If using a contact pad, the pressure can be adjusted by selecting pads of different thicknesses or hardnesses.

[0050] If using the adjustable air cushion 224, after installation, inflate it using the included mini air pump (or manually press the air valve), observe the patient's feedback and the compression effect, and stop inflating once the ideal pressure is reached. To depressurize, press the deflate button.

[0051] The circumferential pressure can also be finely adjusted by slightly adjusting the amount of overlap of the U-shaped headband Velcro.

[0052] Postoperative care and maintenance: When the outer gauze needs to be replaced, simply open the retaining ring 221 to replace it; there is no need to move or compress the auxiliary parts.

[0053] If you need to replace or clean the contact pad / air cushion, simply pull it out of the slot.

[0054] When patients eat or clean their face, they can temporarily loosen the bandage or remove it completely. After the treatment, the bandage can be put back on and quickly restored to its original compression position using the positioning mechanism, ensuring the continuity and precision of the compression therapy.

[0055] After treatment, disposable parts are discarded, while reusable parts are sterilized and kept for future use according to procedures.

[0056] In summary, this solution, through a three-layer modular structure of "U-shaped headband + sliding locking compression component + replaceable contact part", achieves precise adjustment of compression position, multi-mode adjustment of compression force (physical replacement of pads / airbag pressure adjustment), and adjustable circumference, overcoming the shortcomings of traditional bandage fixation, single compression point, and uncontrollable pressure.

[0057] Ergonomic optimization: The selection of elastic materials for the U-shaped headband, the local thickening design, and the headphone-style headband shape significantly improve the comfort of wearing it for a long time and greatly facilitate patients' eating and daily activities.

[0058] Materials and hygiene safety: Reusable parts and disposable sterile parts are strictly distinguished, and their respective disinfection and sterilization paths are clearly defined. The use of disposable contact parts avoids cross-infection and ensures the cleanliness of materials in contact with the wound.

[0059] Functional expandability: By designing a unified snap-fit ​​interface, it can be compatible with contact parts with different functions (such as constant pressure air cushions, hot and cold compress pads, drug sustained release pads, etc.), providing a basic platform for product function expansion and adaptation to different clinical needs.

[0060] Example: Please refer to Figure 6 As shown, the positioning mechanism can also adopt an elastic positioning structure, removing the threaded rod 211 and setting an elastic element inside the slide groove 213. The elastic element pushes the slide rod 214 to slide outward on the inner wall of the slide groove 213, thereby pushing the positioning block 215 to be inserted into the positioning hole 12. The positioning block 215 is set as a hemispherical shape, and can be moved by pushing 21 to slide inside 11 to adjust its position and be positioned by the elastic element. Compared with the threaded rod 211, this structure is simpler to operate, but the positioning stability is worse than that of the threaded rod 211.

[0061] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
