Description

Technical Field

[0001] This utility model relates to the field of medical pillow technology, and in particular to a positioning pillow that can support a medical neck brace. Background Technology

[0002] After cervical spine surgery, patients need to wear a medical neck brace for an extended period in the early stages. The neck brace helps maintain the physiological curvature of the neck and restricts neck movement, thereby maintaining the stability of the cervical spine and allowing the patient to maintain the correct posture for postoperative recovery. Therefore, patients need to wear the neck brace while resting in bed after surgery. The neck brace needs to be worn continuously for more than 48 hours after surgery, and it is not recommended to remove the neck brace during this period. Patients wearing a neck brace will find it inconvenient to lie down while sleeping. Although the neck brace has a certain degree of toughness and elasticity, it is quite thick, generally 1-2 cm thick on one side, and it will wrap around the entire neck, extending close to the back.

[0003] Wearing this type of neck brace to sleep is very uncomfortable. Even with a high pillow, the neck brace will still cause significant discomfort to the patient, making it difficult to guarantee sleep quality and hindering postoperative recovery.

[0004] When wearing a neck brace, a regular pillow cannot match the neck brace, making it difficult for patients to find a comfortable sleeping position. In the later stages of cervical spine surgery, it is no longer necessary to wear a neck brace while sleeping, but the head should not be tilted back or nodding to avoid damage to nerves and blood vessels. It is also necessary to prevent damage to the muscles and ligaments at the surgical site. Therefore, the neck needs to be restricted while the patient is asleep.

[0005] This type of postoperative neck restriction should not involve directly and rigidly fixing the patient's neck. Instead, it allows the patient to twist their neck, but does not allow them to tilt their head back or nod. This makes the patient more comfortable while restricting their movement, which is beneficial for postoperative recovery.

[0006] Based on this, the present invention designs a positioning pillow that can support a medical neck brace to solve the above problems. Utility Model Content

[0007] The purpose of this invention is to provide a positioning pillow that supports a medical neck brace. Addressing the needs of post-cervical spine surgery patients, it includes an adjustable headrest, neck pillow, and shoulder support. The headrest and neck pillow can be individually adjusted in height to suit the patient's head comfort, providing more comfortable support for different patients and those with different sleep preferences, thus offering a more comfortable sleeping posture. A positioning groove is also added to fit the medical neck brace, making it more comfortable for patients to sleep while wearing it. This prevents the neck brace from sliding up and down, but does not restrict the patient's left and right head turning movements. While providing a certain level of comfort, it also prevents the neck brace from shifting, ensuring that the neck brace remains in the designated position to limit neck movement. Furthermore, this device continues to provide neck support even after the neck brace is removed, preventing the patient from nodding or tilting their head back while sleeping, thus avoiding adverse neck movements during sleep. It also provides protection for patients who have removed the neck brace while sleeping.

Detailed Implementation

[0047] Please see Figures 1 to 8 As shown, this utility model provides a positioning pillow that can support a medical neck brace. In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0048] In a specific embodiment of the technical solution of this utility model:

[0049] Includes headrest 1, neck pillow 2, elevation pad 3, inclined support 4, and neck brace 5;

[0050] Headrest 1 is a soft pillow, filled with silicone or latex, giving it resilience and elasticity, providing flexible support for a more comfortable sleep. This is also a commonly used material for pillows.

[0051] The top of the headrest 1 is recessed downwards and has a support groove 12, which is a hemispherical groove that is recessed downwards.

[0052] A limiting strap 13 is also provided on the left and right sides of the top of the headrest 1. The two limiting straps 13 are respectively provided on the left and right sides of the support groove 12. The broken ends of the two limiting straps 13 can be detached and connected to form a complete restraint strap.

[0053] The limiting band 13 is an elastic band, and the ends of the limiting band 13 are also provided with Velcro. The two limiting bands 13 are connected by Velcro.

[0054] The two side limit straps 13 are also equipped with adjustable D-ring buckles;

[0055] A turning groove 15 is recessed on the left and right sides of the top of the headrest 1. The turning groove 15 is a spherical groove with an opening at the top. A turning ball 14 is fixed at the connecting end of each limiting band 13. A turning ball 14 is rotatably locked in each turning groove 15.

[0056] The limiting band 13 is rotatably engaged with the steering ball 14 and the steering groove 15. The steering ball 14 is a complete sphere, while the steering groove 15 is a spherical groove larger than a hemisphere. The top spherical surface of the steering ball 14 is exposed outside the steering groove 15, and the limiting band 13 is connected to the steering ball 14 exposed outside the steering groove 15.

[0057] The neck pillow 2 has chin straps 42 on both sides of its top. The chin straps 42 are riveted and locked to the top of the neck pillow 2. The chin straps 42 are elastic and cross over the positioning groove 22. Like the straps under the helmet, the chin straps 42 are used to support the chin and prevent head movement. The chin straps 42 can be separated and fastened. The fastening method can use either the buckles commonly used on helmets or Velcro. However, the chin straps 42 in this device need to be elastic for cushioning and greater comfort. The chin straps 42 work in conjunction with the restraint strap 13. The restraint strap 13 restrains the forehead, and the chin straps 42 restrain the chin, thus restraining the entire head and providing a safer sleeping position, preventing the patient's head from moving freely while asleep. The chin straps 24 also need to be adjustable in length, similar to the adjustment method and structure of the helmet straps.

[0058] The elevation bladder 3 is an air bladder with an inflation port 31 on its outer wall. The elevation bladder 3 can be detachably and stably placed in the support groove 12. The elevation bladder 3 is a commonly used pillow-shaped air bladder, and the inflation method is the same as that of an air mattress. However, the bottom of the elevation bladder 3 is equipped with Velcro, which allows the elevation bladder 3 to be stably attached to the support groove 12 for effective support.

[0059] Neck pillow 2 is an elastic cushion pillow, which is an elastic pillow pad filled with silicone.

[0060] The lifting frame 11 is an electric lifting platform. The controller of the lifting frame 11 is located outside the neck pillow 2. The lifting frame 11 adjusts its height by controlling the switch.

[0061] The lifting frame 11 is vertically positioned directly below the positioning groove 22. When the patient uses the neck brace 5, their neck is in a higher position, so the height of the neck pillow 2 can be appropriately lowered. When the neck brace 5 is removed, the height of the lifting frame 11 can be raised so that the height of the neck pillow 2 is adapted to the patient's body.

[0062] The neck pillow 2 has a positioning groove 22 with its top facing downwards. The positioning groove 22 is a U-shaped groove with an opening at the top. The neck pillow 2 supports the neck on the back. A lifting frame 11 is installed inside the neck pillow 2. A limiting ridge 21 is provided on each of the head and tail edges of the positioning groove 22. Figure 8 As shown, the limiting rib 21 is slidably installed in the positioning groove 22 through the dovetail groove, so that the limiting rib 21 can be disassembled and can be snapped into the neck support 5 to limit its position.

[0063] The limiting ridge 21 protrudes upward on the inner wall of the positioning groove 22, and the limiting ridge 21 blocks the head and tail sides inside the positioning groove 22; the limiting ridge 21 is a U-shaped convex ridge, and the protrusion height of the limiting ridge 21 inside the positioning groove 22 is 3cm.

[0064] The shape of the limiting ridge 21 is exactly the same as that of the positioning groove 22, which is that it protrudes at the front and back to limit the neck support 5, prevent the neck support from sliding in the head and tail direction, restrict the position of the neck, and ensure that the neck support always maintains effective support.

[0065] It also includes a neck pad 23, which is a flexible soft pad. The neck pad 23 is laid in the positioning groove 22. The thickness of the neck pad 23 is greater than the height of the limiting ridge 21, and the height difference is 5mm.

[0066] When lying flat, the upper and lower ends of the neck brace 5 are secured between the limiting edges 21 on both sides of the head and tail. The neck brace 5 is a commonly used medical neck brace, except that connecting pieces 51 are installed on its left and right sides. The outer side of the limiting band 13 is also equipped with Velcro, which can be attached at any length and position. This allows different traction forces to be applied to the neck brace 5 through the limiting band 13, providing more flexible and comfortable traction restriction for the patient's sleep. Of course, if a more secure connection method is required, the connecting piece 51 can be a snap fastener, and the corresponding outer side of the limiting band 13 also needs to be fitted with snap fasteners for mutual secure locking. The connection structure of the snap fastener to other items is a conventional connection method and will not be described in detail.

[0067] A connecting piece 51 is provided on each of the left and right outer walls of the upper end of the neck brace 5. The limiting strap 13 is fastened to the connecting piece 51 on the neck brace 5 by Velcro. The limiting strap 13 is connected to the neck brace 5 and can elastically connect the neck brace 5, allowing the patient to turn left and right, but not excessively. The elasticity restricts the left and right range of motion of the neck brace 5. The two limiting straps 13 are fastened by Velcro and can be tied to the patient's forehead. When the patient removes the neck brace 5, it restricts the patient from nodding while sleeping, effectively protecting the muscles and nerves of the neck surgery site.

[0068] The inclined support 4 is a flexible cushion. The top of the inclined support 4 is a sloping surface with the head higher than the feet. A connector 42 is provided on the vertical side wall of the headboard side of the inclined support 4. The connector 42 fits into the vertical side wall of the tail end of the neck pillow 2. The inclined support 4 is detachably connected to the neck pillow 2 through the connector 42 to form an integral structure.

[0069] The inclined support 4 has a horizontally opened groove 41 inside, which divides the inclined support 4 into upper and lower layers. The groove 41 is closed on all sides, and multiple springs 43 are vertically arranged inside the groove 41. The upper and lower layers of the inclined support 4 are elastically connected by the springs 43. The lower layer of the inclined support 4 is a wedge-shaped block, and an anti-slip pad is laid on the bottom of the inclined support 4. Multiple springs 43 are evenly distributed in a rectangular array in the groove 41.

[0070] The upper and lower layers of the inclined support 4 are flexibly connected at their tail ends, allowing the tail ends of the upper and lower layers of the inclined support 4 to bend and deform. Therefore, the inclined support 4 can be a silicone pad with high toughness, covered with a soft pad on the outside to improve comfort. This allows the upper and lower layers of the inclined support 4 to open or close without breaking apart.

[0071] The connector 42 is a Velcro or self-adhesive silicone sheet. The inclined support 4 and the neck pillow 2 are glued together as a whole through the connector 42.

[0072] The slant support 4 can also be disassembled and assembled according to different patients' sleeping habits. If shoulder support is needed, use the slant support 4. When not needed, it can be disassembled and the height of the neck pillow 2 can be adjusted to suit the sleep needs.

[0073] When this utility model is in use, when the patient has just finished surgery and needs to sleep, the patient wears the neck brace 5, lies down, and the neck brace 5 is placed in the positioning groove 22 and locked between the two limiting edges 21 at the head and tail. The limiting edges 21 prevent the neck brace 5 from sliding along the head and tail direction, ensuring that the position of the neck brace 5 remains fixed, but does not restrict the patient's head from turning left and right, making the patient more comfortable.

[0074] Next, attach and pull the Velcro on the limiting strap 13 to the connecting piece 51 to provide a certain amount of traction. It is not necessary to use too much force. Just enough to pull and correct the neck. This will provide a certain amount of elastic tension to the patient's neck brace 5, prevent the patient's head from swinging too much from side to side, and protect the patient's neck within a safe range of motion.

[0075] When the patient is more than 2 days post-surgery and can remove the neck brace 5, the patient can use a neck pad 23 to place inside the positioning groove 22 while sleeping. The height of the neck pad 23 is much lower than that of the neck brace 5, so the neck pad 23 can make the positioning groove 22 softer and more comfortable.

[0076] Meanwhile, the two limiting straps 13 on the left and right can be attached to the patient's forehead with Velcro to restrict the patient's nodding movements and effectively protect the nerves and muscles in the neck.

[0077] Both the head pillow 1 and neck pillow 2 of this device can be adjusted in height independently. The head pillow 1 adjusts its height by the inflation of the sump 3, allowing the patient to find a comfortable height. The reclining support 4 provides effective support to the shoulders through multiple springs 43, making sleep more comfortable.

[0078] The head-to-tail direction of this device refers to the direction of the head and foot of the bed when the patient is lying down, and the left and right sides refer to the left and right directions when the patient is lying down. The indicated orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings and is only for the convenience of describing this utility model and simplifying the description. It does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0079] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
