Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary device technology, specifically a postoperative neck fixation pillow. Background Technology

[0002] Following neck surgeries (such as anterior cervical spine surgery, thyroidectomy, and cervical lymph node dissection), patients' necks are vulnerable and require immobilization devices to restrict movement and prevent wound traction, bone graft displacement, or loosening of internal fixation, ensuring healing and surgical outcomes. Currently, clinical practice mainly relies on traditional medical pillows, which are mostly molded cotton pillows, inflatable pillows, or simple concave pillows. These only provide basic support and cannot meet the precise immobilization needs after surgery. Specific shortcomings include: 1. Insufficient fixation strength and lack of targeted clamping structures, relying solely on the pillow's shape: Due to differences in head and neck circumference among patients, the gap is not adjustable, easily leading to head displacement and neck movement. The immobilization effect weakens, especially during turning over or slight movement, failing to restrict neck flexion, extension, and rotation, increasing the risk of complications; 2. Poor fit and positioning: The size of the head and neck support area... 1. Immobilization: The immobilization strength cannot be adjusted according to the postoperative recovery stage (such as strict movement restriction in the early stage and relaxed activity in the middle stage) or the location of the wound. For example, after cervical spine surgery, the cervical spine needs to be stably clamped. Traditional pillows only support the lower part of the neck and cannot restrain the sides of the cervical spine. The fixation effect is concentrated on the soft tissue, and the effectiveness of the fixation is greatly reduced. 2. Limited and single function: It only has a support function and no adjustment and driving structure. Medical staff need to adjust the fixation strength according to the follow-up examination, but they can only add extra auxiliary materials (which are easy to shift and become unbalanced) or change the pillow. The operation is cumbersome and increases the difficulty of nursing care and medical costs. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a postoperative neck fixation pillow, which solves the problem that traditional medical pillows provide low fixation and restraint strength for the head and neck of postoperative patients.

[0004] To achieve the above objectives, this utility model provides a postoperative neck fixation pillow, which consists of a base pillow, two main pillows, and two auxiliary pillows. The two main pillows are arranged opposite each other and are spaced together to form a head groove for accommodating the patient's head. The two auxiliary pillows are arranged opposite each other and are spaced together to form a neck groove for accommodating the patient's neck. The head groove and the neck groove are connected. The base pillow is provided with a first driving member for driving the two main pillows to move synchronously, so that the two main pillows come together or separate to clamp and limit the patient's head, and a second driving member for driving the two auxiliary pillows to move synchronously, so that the two auxiliary pillows come together or separate to clamp and limit the patient's neck.

[0005] The advantages of adopting the above technical solution are as follows: The base pillow provides a stable support foundation for the entire pillow, ensuring the structural load-bearing capacity of the head pillow and auxiliary pillow during installation and movement. The two main pillows are positioned opposite each other to form a head groove, which can precisely adapt to the patient's head placement needs, avoiding head displacement due to lack of support. The first driving component can drive the two main pillows to move synchronously together or apart, adjusting the head clamping force according to the patient's head circumference to achieve personalized head positioning, while ensuring head fixation stability and preventing postoperative head movement from pulling on the wound. The two auxiliary pillows are positioned opposite each other to form a neck groove, conforming to the physiological shape of the neck and providing a dedicated support space for the neck. The second driving component can drive the auxiliary pillows to move synchronously, adjusting the neck clamping strength according to the patient's neck circumference and postoperative recovery stage, avoiding neck shaking that could cause bone graft displacement or internal fixation loosening. The head groove and neck groove are connected to ensure the continuity of head and neck support, conforming to the physiological curve of the human head and neck, improving comfort. Simultaneously, by synchronously limiting the head and neck, it solves the problem of low postoperative head and neck fixation strength in traditional pillows, comprehensively ensuring postoperative recovery.

[0006] This utility model further comprises: the first driving component includes a first adjusting rod, on which two first mating blocks are movably disposed; each of the two first mating blocks has a first through hole through which the first adjusting rod passes; a first thread is formed on the outer peripheral wall of the first adjusting rod; a second thread is formed on the inner peripheral wall of the first through hole for threaded connection with the first thread; the two first threads are arranged in opposite directions; the two first mating blocks correspond one-to-one with the two main pillows, and the top walls of the two first mating blocks are connected to the bottom walls of their respective main pillows; a first rotating hole is horizontally formed on the base pillow, in which the first adjusting rod is rotatably disposed; a first adjusting groove is formed on the top wall of the base pillow corresponding to the positions of the two main pillows; both first adjusting grooves are connected to the first rotating hole; and the two first mating blocks are slidably disposed in the two first adjusting grooves respectively.

[0007] The advantages of adopting the above technical solution are as follows: The first adjusting rod, as the core transmission component of the first driving element, provides a stable power carrier for the movement of the two main pillows, ensuring the effectiveness of power transmission. The first thread on the outer peripheral wall of the first adjusting rod, arranged in opposite directions, matches the second thread in the first through hole of the first mating block, enabling the two first mating blocks to move synchronously in opposite directions when the first adjusting rod is rotated. This eliminates the need to operate the main pillows separately, improving the convenience of adjustment. The two first mating blocks are connected one-to-one with the two main pillows, accurately transmitting the power of the first adjusting rod to the main pillows, ensuring the synchronicity of the main pillow movements and avoiding the effect of unilateral main pillow offset. To ensure effective head fixation, the first rotating hole on the base pillow provides rotational support for the first adjusting rod, ensuring smooth rotation and reducing resistance during adjustment. Meanwhile, the first adjusting groove on the top wall of the base pillow acts as a sliding guide for the first mating block, preventing displacement and ensuring the main pillow moves smoothly along the preset direction, thus improving adjustment accuracy. The overall first driving component has a simple and reliable structure. Through threaded transmission, the clamping force of the main pillow is adjustable, meeting the needs of patients with different head circumferences while maintaining head fixation stability and preventing postoperative head movement from adversely affecting the wound. Furthermore, the transmission structure is not easily damaged, extending the device's lifespan.

[0008] This utility model further comprises: the first driving component includes a second adjusting rod, on which two second mating blocks are movably disposed; each of the two second mating blocks has a second through hole through which the second adjusting rod passes; a third thread is formed on the outer peripheral wall of the second adjusting rod; a fourth thread is formed on the inner peripheral wall of the second through hole for threaded connection with the third thread; the two fourth threads are arranged in opposite directions; the two second mating blocks correspond one-to-one with the two auxiliary pillows, and the top walls of the two second mating blocks are connected to the bottom walls of their respective auxiliary pillows; a second rotating hole is horizontally formed on the base pillow, in which the second adjusting rod is rotatably disposed; a second adjusting groove is formed on the top wall of the base pillow corresponding to the positions of the two auxiliary pillows, and both second adjusting grooves are connected to the second rotating hole; and the two second mating blocks are respectively slidably disposed in the two second adjusting grooves.

[0009] The advantages of adopting the above technical solution are as follows: The second adjusting rod serves as the core of power transmission for the second driving component, providing a stable driving foundation for the movement of the two auxiliary pillows and ensuring effective transmission of adjustment force. Through the reverse-oriented fourth thread on the outer peripheral wall of the second adjusting rod, it engages with the fourth thread within the second through hole of the second mating block. Rotating the second adjusting rod allows the two second mating blocks to slide synchronously in opposite directions, eliminating the need for separate adjustment of the auxiliary pillows, simplifying the operation process, and improving the adjustment efficiency for medical staff. Furthermore, the one-to-one connection between the two second mating blocks and the two auxiliary pillows transforms the rotation of the second adjusting rod into smooth movement of the auxiliary pillows, ensuring the consistency of the movement of the two auxiliary pillows and avoiding the need for separate adjustment. The offset of the secondary pillow causes uneven force on the neck. At the same time, the second rotating hole on the base pillow provides a rotation support point for the second adjustment rod, ensuring smooth rotation of the adjustment rod and reducing jamming during the adjustment process. The second adjustment groove on the top wall of the base pillow constrains the sliding trajectory of the second mating block, preventing the movement of the mating block from deviating from the preset direction, ensuring that the secondary pillow moves along the neck adaptation direction, and improving the accuracy of neck clamping. This drive structure achieves adjustable neck fixation strength through threaded transmission, which can not only adapt to patients with different neck circumferences, but also adjust the limiting force according to the postoperative recovery stage, avoiding excessive neck restraint or insufficient fixation, ensuring the postoperative recovery effect. At the same time, the structure is durable and reduces maintenance costs.

[0010] The present invention further comprises: the beginning ends of the first adjusting rod and the beginning ends of the second adjusting rod both protrude from the base and are provided with a rotating disk; a rotating handle for external medical personnel to rotate is hinged on the rotating disk; a receiving groove for accommodating the rotating handle is opened on the surface of the rotating disk; a base is provided in the first through hole and the second through hole; the ends of the first adjusting rod and the second adjusting rod are rotatably connected to their respective adjacent bases; and the bases are made of plastic material.

[0011] The advantages of adopting the above technical solution are as follows: The rotating disks at the beginning of the first and second adjusting rods increase the contact area for adjustment, making it easier for medical staff to apply force and rotate, thus improving the ease of adjustment. Furthermore, the hinged handle on the rotating disk can be flipped to form a lever that reduces the force required to rotate the adjusting rod, further optimizing the user experience and preventing hand fatigue for medical staff. The groove on the surface of the rotating disk allows the handle to be stored when not in use, preventing it from protruding and causing collision damage, while maintaining a flat appearance and reducing space occupation. The bases in the first and second perforations provide stable support for the end of the adjusting rod, preventing wobbling at the end during rotation and ensuring transmission stability. The plastic base has good wear resistance and lightweight properties, reducing frictional loss during rod rotation, extending component lifespan, and lowering the overall weight of the device, thus improving portability.

[0012] The present invention further comprises: the base pillow is made of hard rubber material and its surface is covered with an elastic pad made of foam material; both the main pillow and the secondary pillow are composed of a pillow core and a pillowcase; the pillow core is made of medical hypoallergenic memory foam material and the pillowcase is made of breathable knitted fabric material.

[0013] The advantages of adopting the above technical solution are as follows: The base pillow, made of hard rubber, possesses excellent structural strength and load-bearing capacity, stably supporting the weight of the main pillow, secondary pillow, and the patient's head and neck, preventing deformation over long-term use and ensuring the stability of the fixation structure. The foam elastic pad on the surface of the base pillow cushions the impact of contact between the base pillow and the patient's body, improving comfort and preventing discomfort caused by direct contact with the hard base pillow. Furthermore, the pillow cores of the main and secondary pillows are made of medical-grade hypoallergenic memory foam, which has excellent softness and resilience, conforming to the physiological curve of the head and neck, dispersing local pressure, and reducing head strain. The pillowcase reduces neck pressure and its hypoallergenic properties lower the risk of skin allergies, making it suitable for postoperative sensitive skin. Made of breathable knitted fabric, it offers excellent breathability and moisture absorption, promoting air circulation, reducing sweat buildup on the head and neck, keeping skin dry, and preventing discomfort caused by stuffiness. The soft, skin-friendly knitted fabric further enhances comfort. The overall material selection balances structural stability, comfort, and safety, ensuring effective head and neck fixation postoperatively while improving the patient experience and reducing discomfort during postoperative care, meeting medical product usage standards.

[0014] The present invention further comprises: the top wall of the main pillow and the inner side wall are connected by a smooth arc surface to form a first arc surface, and the top wall of the secondary pillow and the inner side wall are connected by a smooth arc surface to form a second arc surface.

[0015] The advantages of adopting the above technical solution are as follows: The first arc-shaped surface between the top wall and the inner side wall of the main pillow adopts a smooth arc-shaped transition design, which avoids the pressure caused by right angles or sharp edges contacting the head, reduces the concentration of local pressure on the head, and can better fit the contour curve of the head, improve the fit between the head and the main pillow, enhance the stability of head fixation, and prevent the head from shifting along the edges during movement. The second arc-shaped surface between the top wall and the inner side wall of the secondary pillow is also connected by a smooth arc-shaped surface, which conforms to the physiological shape of the neck, especially the transition area between the sides and the top of the neck, reduces the friction and pressure between the neck and the secondary pillow, and improves the comfort of neck support.

[0018] Postoperative neck immobilization pillow overall procedure: 1. Initial preparation stage: When the device is not in use, the two main pillows and two auxiliary pillows are in the initial open state. The first adjusting rod and the first mating block of the first driving component and the second adjusting rod and the second mating block of the second driving component are all in the initial position. The rotating handle on the rotating disk is stored in the groove to avoid collision caused by the protruding structure. The foam elastic pad on the surface of the base pillow is kept flat, and the breathable knitted fabric pillowcases of the main pillow and auxiliary pillow are in a clean state to ensure the comfort and safety of the patient when in contact.

[0019] 2. Head and neck placement stage: When the patient needs postoperative fixation, first align the head with the head groove above the base pillow, and slowly place the neck in the corresponding neck groove, so that the head is completely contained in the head groove formed by the two main pillows, and the neck is in contact with the neck groove formed by the two secondary pillows. The medical hypoallergenic memory foam cores of the main and secondary pillows are used to initially adapt to the contours of the head and neck. At the same time, the connection design between the head groove and the neck groove ensures continuous support for the head and neck, conforms to the physiological curve of the human body, and avoids positional displacement during the initial placement.

[0020] 3. Head Fixation and Adjustment Stage: Medical staff first flip the handle on the rotating disk at the beginning of the first adjustment rod out of the receiving groove, hold the handle and rotate the rotating disk, causing the first adjustment rod to rotate in the first rotating hole of the base pillow; because the reverse first thread on the outer peripheral wall of the first adjustment rod meshes with the second thread in the first through hole of the first mating block, when the first adjustment rod rotates, the two first mating blocks slide synchronously in the opposite direction along the first adjustment groove on the top wall of the base pillow, thereby causing the two main pillows to come together or separate; according to the patient's head circumference and the postoperative head fixation needs, adjust the main pillow to a suitable clamping force to ensure that the head is stable without shaking and without pressure. After adjustment, put the handle back into the receiving groove.

[0021] 4. Neck Fixation and Adjustment Stage: Using the same operating method as the head adjustment, unfold the handle on the rotating disk at the beginning of the second adjustment rod, and rotate the rotating disk to make the second adjustment rod rotate in the second rotating hole of the base pillow; with the help of the third thread of the second adjustment rod and the fourth thread in the second through hole of the second mating block, drive the two second mating blocks to slide synchronously along the second adjustment groove, thereby realizing the convergence or separation of the two auxiliary pillows; adjust the clamping strength of the auxiliary pillows according to the patient's neck circumference and the postoperative neck recovery stage (such as strict fixation in the early stage and appropriate relaxation in the middle stage) to ensure that the neck fits the neck groove without shaking, avoid bone graft displacement or loosening of internal fixation, and put the handle away after adjustment.

[0022] 5. Post-adjustment storage and maintenance phase: After adjusting the head and neck fixation, check that the rotating handle is fully retracted into the slot to prevent the protruding structure from scratching during use. During use, the hard rubber material of the base pillow provides stable support, the foam elastic pad cushions pressure, and the memory foam cores of the main and secondary pillows continuously conform to the contours of the head and neck. The breathable knitted fabric pillowcase promotes air circulation and keeps the head and neck dry. If the fixation strength needs to be adjusted, the head and neck adjustment steps can be repeated to achieve dynamic adaptation through the drive mechanism until the patient recovers postoperatively and no longer needs fixation. Then, rotate the adjustment rod in the opposite direction to open the main and secondary pillows, allowing the patient to remove the device.
