Description

Technical Field

[0001] This utility model relates to the field of medical and nursing technology, specifically a positioning pillow for bedridden patients to open the airway. Background Technology

[0002] In the field of modern medical care, the care of bedridden patients faces many challenges. Among them, maintaining airway patency and ensuring cervical spine health are key aspects. Due to decreased physical function, impaired consciousness, or the influence of their condition, bedridden patients have weakened airway self-protection and regulation capabilities, making them prone to tongue retraction. Tongue retraction can lead to upper airway narrowing or even blockage, seriously affecting the patient's normal breathing.

[0003] Clinical data shows that approximately 30%-50% of patients who are bedridden for extended periods experience varying degrees of respiratory ventilation problems. This not only prolongs hospital stays but also significantly increases medical costs and patient suffering. Ordinary pillows, when supporting the head, cannot effectively adjust the posture of the patient's head, neck, and back, making it difficult to fully open the upper airway and meet the breathing needs of bedridden patients. Prolonged bed rest keeps the patient's cervical spine in an unnatural position for extended periods. Coupled with a lack of effective support, the pressure on the intervertebral spaces of the cervical spine increases, and the neck muscles remain in a state of tension for a long time, easily leading to problems such as cervical pain and stiffness.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example

[0024] Please see Figure 1-5This utility model provides a technical solution: a positioning pillow for bedridden patients to open their airways, comprising:

[0025] The base pad 1 has a headrest device 2 rotatably connected to its top end, a neck pillow device 3 fixedly connected to its top end, and a back pillow device 4 fixedly connected to its top end. The outer walls of the headrest device 2 and the neck pillow device 3 are fixedly connected to a locking device 5. The headrest device 2 and the neck pillow device 3 at the top end of the base pad 1 can be adjusted according to the patient's resting posture, and the back pillow device 4 can support the patient's body posture.

[0026] The headrest device 2 includes an adjustment plate 20. A passive rod 21 is symmetrically rotatably connected to the bottom end of the adjustment plate 20. An F-shaped rotating rod 22 is rotatably connected to the outer wall of the passive rod 21 via a round rod. A gradient density memory foam 23 is fitted onto the outer wall of the adjustment plate 20. A cotton textile material is fitted onto the outer wall of the gradient density memory foam 23, and longitudinal ventilation channels are provided on the inner wall of the cotton textile material. The inner wall of the adjustment plate 20 is rotatably connected to the bottom end of the base pad 1 via a round rod. The outer wall of the F-shaped rotating rod 22 is connected to the gradient density memory foam 23 and the cotton textile material. The inner wall is rotatably connected, and the F-shaped rotating rod 22 drives the passive rod 21 to rotate at the bottom of the adjusting plate 20, so that the adjusting plate 20 can be adjusted at intervals of 15°. Then, the adjusting block 55 is released, and the sliding tooth 52 is engaged with the limiting tooth 51 due to the elastic force of the compression spring 53, so as to prevent the F-shaped rotating rod 22 from rotating. The inner wall of the gradient density memory foam 23 and the blended fabric 24 has longitudinal ventilation channels to form a good air circulation channel, so that heat and moisture can be discharged in time during patient use.

[0027] The neck pillow device 3 includes two support plates 30. A sliding rod 31 is slidably connected to the inner wall of each support plate 30 via a groove, which is located within the wall of the support rod. An active rod 32 is rotatably connected to the outer wall of each support plate 30. A pull rod 33 is symmetrically rotatably connected to the active rod 32 via a connecting block. A sliding shaft 34 is rotatably connected to the inner wall of the pull rod 33. A passive adjustment rod 35 is fixedly connected to the outer wall of the sliding shaft 34. A dual-density composite structure 36 is fitted onto the outer wall of the support plate 30. A medical-grade silicone breathable groove 37 is fitted onto the outer wall of the dual-density composite structure 36. The bottom end of the support plate 30 is fixedly connected to the top end of the base pad 1. The sliding shaft 34... The outer wall of the active rod 32 is symmetrically slidably connected to the inner wall of the support plate 30 through a sliding groove, and the sliding groove is opened on the inner wall of the support plate 30. The outer wall of the active rod 32 is rotatably connected to the inner wall of the dual-density composite structure 36. By operating the active rod 32, the pull rod 33, the sliding rod 31, the sliding shaft 34 and the passive adjustment rod 35 are driven to move. The sliding shaft 34 slides in the sliding groove of the support plate 30. Then the adjustment block 55 is released. Due to the elastic force of the compression spring 53, the sliding tooth 52 engages with the limiting tooth 51. This can realize the change of the curvature of the C-shaped surface to adapt to the physiological characteristics of different patients' necks, reduce the burden on the neck muscles and maintain the stability of the cervical spine.

[0028] The back pillow device 4 includes a high-elastic PE hollow three-dimensional support 40. The outer wall of the high-elastic PE hollow three-dimensional support 40 is covered with a 3D honeycomb mesh fabric 41. The bottom end of the high-elastic PE hollow three-dimensional support 40 is fixedly connected to the top end of the base pad 1. The back pillow device 4 is composed of a high-elastic PE hollow three-dimensional support and a 3D honeycomb mesh fabric 41. The high-elastic PE hollow three-dimensional support 40 has good elasticity and support, which can effectively disperse the pressure on the patient's back and provide stable support for the back. The 3D honeycomb mesh fabric 41 not only has good breathability, but also ensures that the patient's back skin is dry, reducing the stuffiness and skin problems caused by long-term bed rest.

[0029] The locking device 5 includes a limiting ring 50, with a limiting tooth 51 fixedly connected to the inner wall of the limiting ring 50. A sliding tooth 52 is slidably connected to the outer wall of the limiting tooth 51. A compression spring 53 is fixedly connected to the end of the sliding tooth 52 away from the limiting tooth 51. A limiting strip 54 is slidably connected to the inner wall of the sliding tooth 52. The limiting strip 54 is fixedly connected to the outer wall of the F-shaped rotating rod 22 and the driving rod 32. An adjusting block 55 is slidably connected to the inner wall of the limiting tooth 51. The end of the compression spring 53 away from the sliding tooth 52 is fixedly connected to the side wall of the blended fabric 24 and the dual-density composite structure 36, thus locking the device. The adjusting block 55 in the stopping device 5 is pressed into the limiting ring 50. During this process, since the inner wall of the limiting ring 50 is slidably connected to the limiting tooth 51, the limiting tooth 51 slides inward until the limiting strip 54 on the outer wall of the F-shaped rotating rod 22 stops limiting the limiting tooth 51. Then, the adjusting block 55 is rotated, and the adjusting block 55 drives the F-shaped rotating rod 22 to rotate. The pointer of the adjusting block 55 rotates to the position on the outer wall of the limiting ring 50. Then, the adjusting block 55 is released, and the sliding tooth 52 is engaged with the limiting tooth 51 due to the elastic force of the compression spring 53.

[0030] When in use, the headrest device 2 and neck device at the top of the base pad 1 are adjusted according to the patient's resting posture, and the backrest device 4 can support the patient's body posture.

[0031] When the patient needs to lie flat while supine, the adjusting block 55 in the locking device 5 is pressed into the limiting ring 50. During this process, since the inner wall of the limiting ring 50 is slidably connected to the limiting tooth 51, the limiting tooth 51 slides inward until the limiting strip 54 on the outer wall of the F-shaped rotating rod 22 stops limiting the limiting tooth 51. Then, the adjusting block 55 is rotated, which drives the F-shaped rotating rod 22 to rotate. The pointer of the adjusting block 55 rotates to the position on the outer wall of the limiting ring 50. During this process, the F-shaped rotating rod 22 drives the passive rod 21 to rotate at the bottom of the adjusting plate 20, so that the adjusting plate 20 can be adjusted at intervals of 15°. Then, the adjusting block 55 is released. Due to the elastic force of the compression spring 53, the sliding tooth 52 engages with the limiting tooth 51, preventing the F-shaped rotating rod 22 from rotating.

[0032] After the headrest device 2 is adjusted, the neck device is also adjusted accordingly. First, operate the locking structure by pressing the adjusting block 55 in the locking device 5 into the limiting ring 50. During this process, since the inner wall of the limiting ring 50 is slidably connected to the limiting tooth 51, the limiting tooth 51 slides inward until the limiting strip 54 on the outer wall of the F-shaped rotating rod 22 stops limiting the limiting tooth 51. Then, rotate the adjusting block 55, which drives the F-shaped rotating rod 22 to rotate, and the pointer of the adjusting block 55 rotates. At the stop on the outer wall of the limiting ring 50, the active rod 32 is then operated to drive the pull rod 33, slide rod 31, slide shaft 34 and passive adjustment rod 35 to move. The slide shaft 34 slides in the slide groove of the support plate 30. Then the adjustment block 55 is released, and the sliding tooth 52 is engaged with the limiting tooth 51 due to the elastic force of the compression spring 53. This can change the curvature of the C-shaped surface to adapt to the physiological characteristics of different patients' necks, reduce the burden on the neck muscles and maintain the stability of the cervical spine.

[0033] The back pillow device 4 is composed of a high-elastic PE hollow three-dimensional support and a 3D honeycomb mesh fabric 41. The high-elastic PE hollow three-dimensional support 40 has good elasticity and support, which can effectively disperse the pressure on the patient's back and provide stable support for the back. The 3D honeycomb mesh fabric 41 not only has good breathability, but also ensures that the patient's back skin is dry, reducing the stuffiness and skin problems caused by long-term bed rest.

[0034] The headrest device 2 has longitudinal ventilation channels on the inner wall of the gradient density memory foam 23 and blended fabric 24, the neck pillow device 3 has a dual density composite structure 36 and medical silicone textured breathable grooves 37, and the back pillow device 4 has a 3D honeycomb mesh fabric 41. These breathable designs work together to form a good air circulation channel. During the patient's use, heat and moisture can be discharged in time, keeping the patient's skin dry, improving the comfort of use, and reducing bacterial growth.
