Description

Technical Field

[0001] This utility model relates to the field of fixed pillow technology, specifically an adjustable head-fixing pillow. Background Technology

[0002] A cervical fixation pillow can effectively stabilize the neck, prevent cervical spine displacement or injury caused by improper movement or external force, ensure cervical spine stability, thus improve the speed of postoperative recovery of the neck and reduce the patient's pain.

[0003] The existing fixation pillow is placed directly on the hospital bed to fix the neck. However, because the fixation pillow is not adjustable, some patients cannot fully fit their necks onto the fixation pillow, which can cause discomfort.

[0004] To address the shortcomings of existing technologies, an adjustable head fixation pillow for post-cranial surgery, disclosed in prior art (CN216365664U), allows for adjustment of the size of pillow block A through the interlocking of a fixing bolt and a pin via an adjustment hole. This ensures that the size of pillow block A adapts to the patient's head. Simultaneously, an adjustable neck pad is provided on the inner side of pillow block B to meet the different needs of patients for neck height. This solves the problems of existing head fixation pillows, which, due to their fixed size, are poorly adaptable to patients with different head sizes, causing discomfort and head wobbling after prolonged use. Furthermore, the varying neck height requirements of patients lead to neck fatigue due to unsuitable neck heights, failing to meet the needs of diverse users.

[0005] To address the existing deficiencies, the existing publication number CN219501405U, 202320620797.X, describes an adjustable cervical pillow for postoperative head use. By adjusting the height adjustment pad, it allows the cervical spine to be in a comfortable position, achieving the dual functions of adjusting the fixed width of the head and correcting the cervical spine curve.

[0006] In actual use, although the device can be adjusted to accommodate different patients, patients' heads vary in size. Relying solely on adjusting the height to fix the head of patients with different head shapes may cause discomfort for some patients when using it.

[0007] Therefore, we proposed that an adjustable headrest pillow can effectively solve the above problems. Utility Model Content

[0008] The purpose of this invention is to provide an adjustable head-fixing pillow to solve the problem mentioned in the background art, where the current market only relies on adjusting the height to fix the head of patients with different head shapes, which causes discomfort for some patients when using it.

[0032] Example 1:

[0033] This invention solves the problem that existing methods rely solely on height adjustment to fix the head of patients with different head shapes, which can cause discomfort for some patients. By moving the protrusion 7, the spacing can be adjusted, thereby improving adaptability. The invention discloses:

[0034] The base 1 is placed on the hospital bed. It also includes: a slot 2 is provided inside the base 1, and a slide rod 3 is slidably connected inside the slot 2. An adjusting pillow 6 is slidably connected inside the slide rod 3. A protrusion 7 is slidably connected to the bottom of the slide rod 3. The bottom of the protrusion 7 is semi-circular and extends into the interior of the groove 8 to form a locking mechanism. The grooves 8 are evenly spaced on the base 1, and the top of the grooves 8 is connected to the bottom of the slot 2. A first spring 9 is connected to the top of the protrusion 7, and the top of the first spring 9 is connected to the interior of the slide rod 3. A slider 4 is fixed to the bottom of the slide rod 3, and the outer end of the slider 4 extends into the interior of the slide groove 5 to form a sliding mechanism.

[0035] Test Figures 1 to 4 The base 1 is placed on the hospital bed. Then, the adjustable pillow 6 is pulled according to the patient's head shape. The movement of the adjustable pillow 6 moves the slide bar 3, which in turn moves the slider 4 to slide inside the slide groove 5. The movement of the slide bar 3 moves the protrusion 7, which then presses against the groove 8. The protrusion 7 is then pressed into the slide bar 3, and the movement of the protrusion 7 compresses the first spring 9. This causes the protrusion 7 to disengage from the groove 8, thus adjusting the spacing between the adjustable pillows 6. After moving to the appropriate position, the force of the first spring 9 pushes the protrusion 7 to move, allowing the protrusion 7 to extend into the groove 8 and engage, thus fixing the adjustable pillow 6. This allows the patient's head to be placed on the adjustable pillow 6 for fixation, facilitating postoperative recovery. The adjustment of the adjustable pillow 6 also improves its practicality and provides better comfort for the patient.

[0036] Example 2:

[0037] This utility model solves the problem of cumbersome height adjustment in existing systems. The pawl 10 allows for rapid height adjustment. The following is disclosed:

[0038] The bottom of the adjusting pillow 6 is rotatably connected to a pawl 10, and the upper side of the outer end of the pawl 10 is arc-shaped. The inner end of the pawl 10 is connected to a second spring 12, and the inner end of the second spring 12 is connected to the inside of the adjusting pillow 6. The outer end of the pawl 10 extends into the inside of the slot 11 to form a lock, and the slot 11 is evenly spaced on the slide bar 3.

[0039] refer to Figure 2 , Figure 5 and Figure 6 By pulling the adjusting pillow 6, the adjusting pillow 6 can slide inside the slide rod 3. The movement of the adjusting pillow 6 drives the pawl 10 to move, so that the pawl 10 will be squeezed against the slot 11. Therefore, the pawl 10 is squeezed and rotates into the adjusting pillow 6. The rotation of the pawl 10 will disengage from the slot 11, and the rotation of the pawl 10 will squeeze the second spring 12, so that the second spring 12 will be compressed. After the adjusting pillow 6 is adjusted to a suitable height, the force of the second spring 12 pushes the pawl 10 into the slot 11 to form a lock, thereby fixing the height of the adjusting pillow 6, thus achieving the purpose of convenient and quick height adjustment.

[0040] Example 3:

[0041] This utility model solves the problem that the adjusting pillow 6 cannot be reset in Embodiment 2. It allows for quick reset by moving the pull ring 13. The following is disclosed:

[0042] The inner end of the pawl 10 is connected to a pull ring 13, and the top of the pull ring 13 extends out of the interior of the adjusting pillow 6 to form a sliding mechanism. The bottom bend of the pull ring 13 is fitted with a roller 14, and the roller 14 is connected to the interior of the adjusting pillow 6 through a bearing.

[0043] refer to Figures 1 to 3 , Figure 5 and Figure 6 By pulling the pull ring 13, the pull ring 13 can slide on the adjusting pillow 6. The movement of the pull ring 13 drives the pawl 10 to rotate through the roller 14. The rotation of the pawl 10 will disengage from the slot 11, and then the weight of the adjusting pillow 6 will reset it. This allows the adjusting pillow 6 to be quickly reset, thereby further improving the convenience of adjustment.

[0044] Working principle: When using this adjustable headrest pillow, first, refer to... Figures 1 to 4The base 1 is placed on the hospital bed, and then the adjustable pillow 6 is pulled according to the patient's head shape. The movement of the adjustable pillow 6 moves the slide bar 3, which in turn moves the protrusion 7. The protrusion 7 moves and squeezes against the groove 8, causing it to slide inwards from the slide bar 3. This allows the protrusion 7 to disengage from the groove 8, thus adjusting the spacing between the adjustable pillows 6. After moving to the appropriate position, the force of the first spring 9 pushes the protrusion 7 to move, thereby fixing the adjustable pillow 6. This allows the patient's head to be placed on the adjustable pillow 6 for fixation, facilitating postoperative recovery. The adjustable pillow 6 also improves practicality and provides better comfort for the patient during use.

[0045] refer to Figure 2 , Figure 5 and Figure 6 By pulling the adjusting pillow 6, the adjusting pillow 6 can slide inside the slide bar 3. The movement of the adjusting pillow 6 drives the pawl 10 to move, thus causing the pawl 10 to be squeezed and rotated inside the adjusting pillow 6. The rotation of the pawl 10 will disengage from the slot 11, and the rotation of the pawl 10 will squeeze the second spring 12. After the adjusting pillow 6 is adjusted to the appropriate height, the force of the second spring 12 pushes the pawl 10 to extend into the slot 11 to form a lock, thereby achieving the purpose of convenient and quick height adjustment.

[0046] refer to Figures 1 to 3 , Figure 5 and Figure 6 By pulling the pull ring 13, the pull ring 13 can slide on the adjusting pillow 6, which causes the pawl 10 to rotate and disengage from the slot 11. Then, the weight of the adjusting pillow 6 is used to reset it, which further improves the convenience of adjustment.
