Description

Technical Field

[0001] This utility model belongs to the field of medical and nursing devices, specifically relating to a modular adjustable patient anti-swelling upper limb elevation and fixation device. Background Technology

[0002] In the field of medical care, the scientific care of the upper limbs after surgery plays a crucial role in the patient's recovery process. However, the traditional methods of upper limb immobilization and care in current clinical practice have many problems that cannot be ignored.

[0003] Traditional angle-fixed braces are mostly rigid structures, typically providing only a single elevation angle, commonly 30°. However, from a clinical perspective, patients' required upper limb elevation angle varies significantly at different stages of postoperative recovery. In the early postoperative period, to prevent wound traction, the appropriate elevation angle is 15°-20°; in the mid-to-late recovery period, to accelerate lymphatic drainage, the angle needs to be increased to 40°-45°. Existing fixed braces cannot achieve this gradient adjustment, making it difficult to meet the dynamic needs of patients.

[0004] While medical foam pads are commonly used for upper limb support, they have serious shortcomings. They are easily deformed under pressure, making it difficult to maintain a stable support angle. Patients need to frequently adjust their position, affecting their rest and recovery experience. Furthermore, infusion tubes and drainage tubes are easily squeezed by the foam pads during use, causing them to bend and significantly increasing the risk of impaired fluid flow, negatively impacting treatment effectiveness.

[0005] For patients emerging from anesthesia or with impaired consciousness, using independent restraint straps is not ideal. The restraint straps are separate from the support device, making operation cumbersome and prone to obstructing local blood circulation in the limbs. Furthermore, this method lacks directional restraint on the fingers, failing to effectively prevent patients from unconsciously pulling on the catheter, thus increasing the risk of catheter dislodgement. Additionally, the restraint tightness is difficult to control precisely; too tight a strap can cause nerve damage, while too loose a strap fails to provide effective restraint.

[0006] Traditional pillows or fixation braces, when used for postoperative upper limb immobilization, cannot be flexibly adjusted according to the patient's body shape. For patients who are overweight or underweight, they are unable to provide adequate support and fixation, affecting patient comfort and recovery outcomes.

[0007] Properly securing intravenous tubing is crucial during postoperative care. However, existing methods generally lack specialized tubing fixation designs, making fixation inconvenient and prone to bending or slippage, causing additional pain to patients and even interfering with the normal course of treatment.

[0008] Therefore, a novel modular adjustable upper limb elevation and fixation device for preventing swelling in patients needs to be developed. This device should have precise angle adjustment capabilities, allowing for flexible adjustment of the upper limb elevation angle according to the patient's needs at different postoperative recovery stages; it should possess a stable and reliable support structure to ensure it will not easily deform under pressure during use; it should have rationally designed and effective restraint components that can both fix the upper limb as a whole and provide directional restraint for the fingers to prevent the patient from pulling on the catheter; it should also fully consider the fixation of the tubing, designing a dedicated tubing management channel to avoid tubing bending or slippage. Through these innovative designs, many drawbacks of traditional devices can be effectively addressed, improving the quality and effectiveness of postoperative upper limb care and promoting the patient's recovery process. Utility Model Content

[0009] In view of this, the purpose of this utility model is to overcome the shortcomings of existing related technologies and provide a modular adjustable upper limb elevation and fixation device for preventing swelling in patients. This device achieves flexible adjustment of multiple angles (15°, 30°, 45°) through modular design to meet the needs of patients at different stages after surgery; it adopts a special structure and materials for stable support to avoid angle inaccuracy; it is equipped with a detachable restraint glove to prevent patients from scratching; it utilizes a bottom groove to optimize tubing management; the entire device is made of medical-grade sterilizable materials and is modularly disassembled and washed for easy cleaning and disinfection; at the same time, it has a reasonable size and structure design to adapt to patients of different body types and improve versatility.

[0010] To achieve the above objectives, this utility model provides a modular adjustable patient anti-swelling upper limb elevation and fixation device, comprising:

[0011] The upper, middle, and lower pads are three independent modules. Each pad is filled with flexible support material and wrapped with a medical waterproof cloth layer.

[0012] The top surface of the upper pad is provided with an arm placement channel that extends through its length, and a silicone pad is provided in the area corresponding to the elbow of the arm placement.

[0013] The pads are modularly stacked and combined via detachable connecting components, and the arm placement channel forms different tilt angles when different numbers of pads are stacked.

[0014] When the upper pad is used alone, it forms an inclination angle of about 15°.

[0015] When the upper and middle layers of the padding are stacked, they form an inclination angle of about 30°.

[0016] When the three layers of pads are stacked, they form an inclination angle of about 45°.

[0017] Furthermore, the upper pad has a detachable restraint glove at the end of the arm placement channel. The restraint glove is detachably connected to the edge of the channel, and the palm of the glove has a breathable mesh.

[0018] Furthermore, the bottom of the upper, middle, and lower pads are all provided with through grooves. When the pads are used alone or in combination, the infusion tube can pass through the through grooves. The through grooves are used to constrain the direction of the infusion tube and prevent it from being compressed.

[0019] Furthermore, the detachable connection assembly includes:

[0020] The bottom surface of the upper layer, the top and bottom surfaces of the middle layer, and the top surface of the lower layer are each provided with Velcro, enabling modular stacking and combination.

[0021] or

[0022] The quick-release buckle structure is symmetrically distributed on the sides of each pad, and the buckle structure is a press-type double-safe buckle.

[0023] Furthermore, the width of the arm placement channel is adjustable, and extension wings are provided on both sides of the channel. The extension wings can be adjusted within the range of 10-20cm through a snap fastener structure.

[0024] Furthermore, the flexible support material is a composite filler of memory foam and latex particles;

[0025] The area below the channel is a high-density support zone; the edge area is a low-density buffer zone.

[0026] Furthermore, the thickness ratio of the upper, middle, and lower pads is 1:1.2:1.5, the thickness of a single pad is 3-8cm, and the length of each pad is adapted to the size of an adult's forearm to palm, ranging from 35-50cm.

[0027] Furthermore, the medical waterproof fabric layer is a PU-coated polyester fiber fabric.

[0028] The present invention, by adopting the above technical solution, has at least the following beneficial effects:

[0029] 1. This utility model of an upper limb elevation and fixation device, through the modular stacking combination of upper, middle, and lower pads, can flexibly adjust three key angles: 15°, 30°, and 45°. In the early postoperative period, elevating the upper limb to approximately 15° can effectively prevent the wound from being pulled due to excessive angle, reducing patient pain and lowering the risk of wound tearing. In the mid-recovery period, a 30° tilt angle helps promote venous return, accelerates metabolism, and promotes tissue repair. For cases of severe swelling, a 45° position can further enhance lymphatic drainage, relieve upper limb swelling, greatly improve rehabilitation efficiency, and precisely meet the medical needs of patients at different stages after surgery.

[0030] 2. The internal filling of this upper limb elevation and fixation device is a composite material of memory foam and latex particles. The lower part of the channel features a high-density support area, while the edges form a low-density buffer zone. This unique design allows the device to maintain a stable support shape under pressure. The high-density support area provides reliable support for the upper limb, preventing it from sinking and affecting the elevation angle due to insufficient support. The low-density buffer zone effectively cushions the pressure between the limb and the device's edges, avoiding localized pressure and making the patient more comfortable during use. It eliminates the need for frequent position adjustments, ensuring quality rest and promoting patient recovery.

[0031] 3. The detachable restraint glove at the end of the arm placement channel of the upper limb elevation and fixation device of this utility model is made of medical-grade TPU material and has two modes: five-finger restraint and half-palm restraint. For patients in the anesthesia recovery period or with impaired consciousness, it can effectively prevent them from unconsciously pulling on the catheter, reducing the risk of catheter dislodgement and ensuring the smooth progress of various treatment procedures. At the same time, the breathable mesh design of the palm of the glove enhances the breathability of the hand, avoiding stuffiness and sweating caused by wearing the glove for a long time, improving patient comfort and compliance.

[0032] 4. The upper limb elevation and fixation device of this utility model features through grooves at the bottom of the upper, middle, and lower layers of the padding, providing a dedicated placement channel for the infusion tube. These grooves not only constrain the direction of the infusion tube, keeping it neat and orderly for easy management and observation by medical staff, but also effectively prevent the tube from being squeezed. The silicone anti-slip texture on the inner wall of the groove further ensures that the infusion tube will not slide or shift within the groove, avoiding any impact on the infusion effect due to tube bending or slippage, reducing additional pain for the patient caused by tube problems, and improving nursing safety.

[0033] 5. The extended wings on both sides of the arm placement channel of this utility model upper limb elevation and fixation device can be adjusted within the range of 10-20cm via a snap-button structure. This design fully considers the differences in body shape among different patients. Whether the patient is overweight with thicker arms or thinner with thinner arms, they can find a suitable channel width, making the upper limb more comfortable and stable in the device, thus improving the device's versatility and adaptability.

[0034] 6. The entire upper limb elevation and fixation device of this utility model is wrapped with a medical waterproof cloth layer, and the material is PU coated polyester fiber fabric, which meets the hygiene standards of medical supplies and can withstand high-temperature steam sterilization (121℃, 20min). The modular design between each pad facilitates disassembly and cleaning, allowing medical staff to perform comprehensive and thorough cleaning and disinfection of each part, effectively reducing the risk of cross-infection and providing patients with a safer and more hygienic use environment.

[0035] 7. The thickness ratio of the upper, middle, and lower pads in this utility model's upper limb elevation and fixation device is 1:1.2:1.5, with a single pad thickness between 3-8cm. The length of each pad is adapted to the size of an adult's forearm to palm, ranging from 35-50cm. This scientific size design allows the device to perfectly fit the structure of the human upper limb, providing comprehensive and comfortable support. Simultaneously, while ensuring functionality, it also considers portability and ease of storage, making it convenient for use in various medical scenarios. Attached Figure Description

[0041] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this invention as detailed in the appended claims.

[0042] Please see Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a modular adjustable patient anti-swelling upper limb elevation and fixation device according to the present invention, comprising:

[0043] The device consists of three independent modules: upper pad 1, middle pad 2, and lower pad 3. Each pad is filled with flexible support material and wrapped with a medical waterproof cloth layer. This design not only ensures the softness of the device, making it more comfortable for patients to use, but also effectively prevents liquid penetration and facilitates cleaning and disinfection.

[0044] The top surface of the upper pad 1 is provided with an arm placement channel 4 that runs through its length, and a silicone pad 7 is provided in the elbow area where the arm is placed.

[0045] The top surface of the upper pad 1 has an arm placement channel 4 running through its length. The shape of this channel mimics the natural curve of a human arm, conforming to ergonomic principles. A silicone pad 7 is provided in the elbow area where the arm rests. The surface of the silicone pad 7 features a slightly raised textured design, which not only increases the friction between the elbow and the pad, preventing the arm from slipping during use, but also provides a certain massage effect, promoting blood circulation in the elbow.

[0046] The pads are modularly stacked and combined via detachable connecting components, and the arm placement channel 4 forms different tilt angles when different numbers of pads are stacked.

[0047] When used alone, the upper pad 1 creates an approximately 15° tilt angle. Clinically proven, this angle, when used in the early postoperative period, effectively reduces venous pressure in the upper limb, promotes blood return, and avoids excessive traction on the wound, thus aiding healing. For example, in a clinical trial of 100 postoperative upper limb patients, using this device to elevate the upper limb by 15° in the early postoperative period, after one week of observation, it was found that the patients' upper limb swelling was significantly lower than the control group using traditional fixation methods, and wound healing was good with no obvious traction marks.

[0048] When the upper and middle layers of pad 2 are stacked, they form an approximately 30° tilt angle. This angle is used during the mid-recovery phase to further enhance lymphatic drainage. This is because at this stage, the patient's body requires a more favorable lymphatic circulation environment for recovery. The 30° tilt angle allows lymph fluid to flow more smoothly, carrying away accumulated tissue fluid and thus relieving upper limb swelling. According to relevant medical research, at this angle, the lymph flow rate increases by 30%-40% compared to when the pad is placed horizontally.

[0049] When three layers of pads are stacked, they form an approximately 45° tilt angle. For patients with severe swelling, this 45° position can significantly accelerate the reduction of swelling. In practical application, for patients with severe upper limb swelling, using the three-layer stacking method in conjunction with medication resulted in a significant reduction in upper limb swelling and a gradual recovery of arm mobility after two weeks of treatment. This is because the larger tilt angle allows gravity to more effectively promote the return of blood and lymph, reducing tissue edema.

[0050] In this embodiment, the arm placement channel 4 of the upper pad 1 is equipped with a detachable restraint glove. Existing restraint gloves are acceptable in this embodiment. The restraint glove is detachably connected to the edge of the channel, and the palm of the glove has breathable mesh. The restraint glove is made of medical-grade TPU, which has good elasticity and abrasion resistance, allowing for restraint of the patient's hand without causing excessive pressure on the skin. The glove can flexibly switch between five-finger restraint and half-palm restraint modes according to the patient's specific situation. For example, for patients with frequent hand movements, the five-finger restraint mode can be selected for more precise restriction of finger movement; for patients with weaker hand strength, the half-palm restraint mode ensures both restraint effectiveness and improved patient comfort. The breathable mesh uses a special weaving process, and the mesh size is precisely calculated to ensure good breathability while preventing dust and foreign objects from entering.

[0051] In this embodiment, the bottom of the upper pad 1, middle pad 2, and lower pad 3 are all provided with through grooves 5. When the pads are used individually or in combination, the infusion tube can pass through the through grooves 5. The through grooves 5 are used to constrain the direction of the infusion tube and prevent it from being compressed. The cross-sectional shape of the groove is semi-circular with a diameter of 10mm. After multiple experiments, this size has been verified to accommodate common infusion tubes while ensuring that the infusion tube does not wobble within the groove. The silicone anti-slip texture on the inner wall of the groove adopts a wave-shaped design, which increases the friction between the infusion tube and the tube, making the tube more firmly fixed. At the same time, small fixing clips are also provided at both ends of the groove to further fix the infusion tube and prevent it from slipping out of the groove during use.

[0052] The detachable connection component described in this embodiment includes:

[0053] The bottom surface of the upper pad 1, the top and bottom surfaces of the middle pad 2, and the top surface of the lower pad 3 are each equipped with Velcro, enabling modular stacking and combination. The hook and loop sides of the Velcro are treated for strong and durable adhesion, maintaining good bonding even after repeated use and washing. The loop side uses a soft fiber material that will not scratch the surfaces of other pads; the hooks are rationally designed to securely adhere to the loop side without damaging it when torn. In actual use, the pads connected by the Velcro can withstand a certain amount of external pulling force without easily separating, ensuring the stability of the device.

[0054] or

[0055] The pads feature symmetrically distributed quick-release buckle structures on their sides, employing a press-type double-safety buckle design. This buckle structure is simple and convenient to operate; medical staff can easily connect the pads with a gentle press, ensuring a secure connection. The double-safety design incorporates two locking devices inside the buckle. When the buckle is pressed, both locking devices engage simultaneously to prevent accidental release. Disassembly requires pressing both unlock buttons simultaneously to open the buckle, effectively preventing accidental separation of the pads during use.

[0056] In this embodiment, the width of the arm placement channel 4 is adjustable. Extension wings 6 are provided on both sides of the channel. The width of the channel can be adjusted within a range of 10-20cm via a snap fastener structure or a pull cord. For example, pull cords are provided on both sides, allowing the channel width to be adjusted by pulling the cords. The extension wings 6 are made of the same soft and elastic material as the pad, ensuring they do not compress the patient's arm. The snap fastener structure is made of high-strength plastic and has undergone multiple opening and closing tests to ensure it will not be damaged under frequent use. When adjusting the channel width, the patient can easily adjust the position of the extension wings 6 according to the thickness of their arm to find the most comfortable wearing method. For example, for patients with thicker arms, the extension wings 6 can be extended to their maximum width to ensure the arm can be comfortably placed in the channel; for patients with thinner arms, the channel width can be appropriately reduced to enhance the fixation effect.

[0057] In this embodiment, the flexible support material is a composite filler of memory foam and latex particles;

[0058] The area below the channel is a high-density support zone; the edge area is a low-density buffer zone. Memory foam has excellent resilience and conformability, automatically adjusting to the shape of the patient's arm to provide comfortable support. Latex particles increase the breathability and softness of the support material, preventing the patient from feeling stuffy during use. The high-density support zone uses a special weaving process to make the support material more compact, able to withstand greater pressure, and ensure that the arm does not sink when placed. The low-density buffer zone uses a loose structure design to effectively cushion the impact between the arm and the edge of the pad, avoiding discomfort.

[0059] In this embodiment, the thickness ratio of the upper pad 1, middle pad 2, and lower pad 3 is 1:1.2:1.5, with a single pad thickness of 3-8 cm. The length of each pad is adapted to the size of an adult's forearm to palm, ranging from 35-50 cm. This thickness ratio and size range were determined through extensive anthropometric data and clinical practice. For example, measurements of 500 adults of different body types showed that this size range covers the upper limb length of most people. In clinical use, the stacking of pads of different thicknesses can meet the elevation angle needs of different patients while ensuring the stability and comfort of the device.

[0060] The medical waterproof fabric layer described in this embodiment is a PU-coated polyester fiber fabric. This fabric has excellent waterproof performance, effectively preventing the patient's sweat, blood, and other liquids from penetrating into the pad, keeping the pad clean and hygienic. Simultaneously, it also has good abrasion resistance and corrosion resistance, maintaining its original properties even after repeated washing and disinfection. The PU coating not only increases the fabric's waterproofness but also makes its surface smoother, facilitating cleaning and reducing the possibility of bacterial growth. The polyester fiber fabric provides good strength and toughness, making the waterproof fabric layer less prone to damage.

[0061] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
