Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical device technology, specifically referring to an adjustable medical pillow for ICU critically ill patients. Background Technology
[0002] In ICU clinical care, critically ill patients often experience confusion, loss or limitation of limb movement, require prolonged bed rest, and are unable to adjust their position independently. Traditional medical pillows for critically ill ICU patients have the following problems:
[0003] (1) Traditional pillows have a fixed support height, which cannot be flexibly adjusted according to individual patient differences and treatment needs. If the support height is too high or the support position is improper, it will cause excessive tension in the neck muscles. Long-term bed rest can easily lead to neck muscle strain, and even cause cervical spine deformation due to imbalance of force on the cervical spine, which will aggravate the patient's pain and increase the probability of nursing complications.
[0004] (2) When patients adjust their neck support, they often need to fix their head to prevent the head from shifting with the neck support. Slight unconscious movements of the patient can cause the head to tilt backward, which can lead to airway obstruction, intracranial pressure fluctuations and other safety hazards. Utility Model Content
[0005] This invention overcomes the shortcomings of existing technologies and provides an adjustable medical pillow for ICU patients. It utilizes the eccentric characteristics of a camshaft to achieve longitudinal height adjustment of the neck support plate, flexibly adjusting the height according to the individual patient's neck support needs, always maintaining the natural forward curvature of the cervical spine, and reducing the risk of position-related complications. Simultaneously with the neck support plate's rise and fall, the drive shaft pulls a slide rod via a guide wire, causing the limiting baffle to move laterally, ensuring the limiting baffle remains close to the back of the patient's head, avoiding safety risks such as airway obstruction and intracranial pressure fluctuations, and guaranteeing patient positional stability.
[0006] The technical solution adopted by this utility model is as follows: This solution provides an adjustable medical pillow for ICU critically ill patients, including a base and a pillow surface. The pillow surface is fixedly mounted on the top wall of the base. A transmission shaft is rotatably connected to the inner wall of the base. A neck support plate is longitudinally slidable on the top wall of the base. The neck support plate is in contact with the transmission shaft and moves up and down longitudinally along the top wall of the base under the push of the driven rod to adapt to different neck support needs of patients. A limiting baffle is laterally slidable on the top wall of the base. The limiting baffle is in transmission cooperation with the transmission shaft and is close to the back of the patient's head to restrict the head from tilting backward.
[0007] Furthermore, a camshaft is fixedly provided on the circumferential wall of the drive shaft to convert the rotational motion of the drive shaft into the lifting motion of the neck support plate.
[0008] Furthermore, a driven rod is fixedly provided at the bottom end of the neck support plate. The driven rod is longitudinally slidably connected to the top wall of the base. The bottom end of the driven rod is in contact with the camshaft, bearing the eccentric pushing force of the camshaft and driving the neck support plate to slide longitudinally.
[0009] Furthermore, a guide wire is fixed on the circumferential wall of the drive shaft, which drives the slide bar to move laterally by pulling force, thereby realizing the synchronous movement of the limiting baffle.
[0010] Furthermore, a sliding rod is fixedly provided at the bottom end of the limiting baffle. The sliding rod is laterally slidably connected to the top wall of the base. The other end of the guide wire is fixedly connected to the bottom end of the sliding rod. The guide wire receives the tension transmitted by the transmission shaft and drives the limiting baffle to move.
[0011] Furthermore, a spring is fixedly provided on the side wall of the slide rod, and the other end of the spring is fixedly connected to the inner wall of the base.
[0012] Furthermore, the base has a limiting groove, and one end of the drive shaft is coaxially slidably provided with a limiting cap. The limiting cap and the limiting groove engage and constrain each other, and the limiting groove is used to limit the rotation of the limiting cap and the drive shaft.
[0013] The beneficial effects of this utility model by adopting the above structure are as follows:
[0014] (1) The camshaft eccentric structure drives the driven rod to lift the neck support plate, avoiding the problem of the neck being suspended or excessively compressed, and always maintaining the physiological curvature of the cervical spine's natural forward curvature, reducing the risk of complications such as neck muscle strain and cervical spine deformation caused by improper posture.
[0015] (2) While the neck support plate is raised and lowered, the drive shaft pulls the slide bar and the limiting baffle in sync through the guide wire, so that the limiting baffle is always close to the back of the patient's head, avoiding the problem of head tilting back when adjusting the neck support with traditional pillows, avoiding the risks of airway obstruction and intracranial pressure fluctuation caused by head displacement, and ensuring the patient's position safety.

[0021] The accompanying drawings are provided to further understand the present invention and form part of the specification. They are used together with the embodiments of the present invention to explain the present invention and do not constitute a limitation thereof. Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0023] Example 1: Please refer to Figures 1-4 This embodiment provides an adjustable medical pillow for ICU patients, including a base 1 and a pillow surface 2. The pillow surface 2 is fixedly mounted on the top wall of the base 1. A drive shaft 3 is rotatably connected to the inner wall of the base 1. A cam shaft 4 is fixedly mounted on the circumferential wall of the drive shaft 3. A guide wire 5 is fixedly mounted on the circumferential wall of the drive shaft 3. A limiting cap 6 is coaxially slidably mounted on one end of the drive shaft 3. The limiting cap 6 is drively connected to the drive shaft 3. A limiting groove 7 is formed on the side wall of the base 1. The limiting cap 6 and the limiting groove 7 engage and constrain each other. The top wall of the base 1 has a longitudinal... A neck support plate 8 is slidably provided, and a driven rod 9 is fixedly provided at the bottom end of the neck support plate 8. The driven rod 9 is longitudinally slidably connected to the top wall of the base 1, and the bottom end of the driven rod 9 is movably in contact with the camshaft 4. A limiting baffle 10 is slidably provided laterally on the top wall of the base 1, and a sliding rod 11 is fixedly provided at the bottom end of the limiting baffle 10. The sliding rod 11 is slidably connected to the top wall of the base 1 laterally. The other end of the guide wire 5 is fixedly connected to the bottom end of the sliding rod 11. A spring 12 is fixedly provided on the side wall of the sliding rod 11, and the other end of the spring 12 is fixedly connected to the inner wall of the base 1.
[0024] In this embodiment, when the patient's neck support is insufficient, the limiting cap 6 is grasped and pulled outward, causing the limiting cap 6 to disengage from the limiting groove 7 on the side wall of the base 1, releasing the meshing constraint between the limiting cap 6 and the limiting groove 7. At this time, the transmission shaft 3 is in a rotatable state. The limiting cap 6 is rotated counterclockwise, and the transmission shaft 3 drives the camshaft 4 to rotate synchronously. The eccentric structure of the camshaft 4 pushes the driven rod 9 to move upward. At the same time, the medical staff observes the patient's neck condition. The neck support plate 8 is raised until the patient's neck muscles relax and the rotation stops.
[0025] During the rotation of the drive shaft 3, the guide wire 5 is simultaneously wound around the drive shaft 3. The winding length increases with the increase of the rotation angle. The guide wire 5 pulls the slide rod 11 to move towards the neck support plate 8. The limiting baffle 10 moves to be close to the back of the patient's head, restricting the head from moving backward and preventing the head from tilting backward due to the rise of the neck support. This maintains the natural physiological curve of the neck and head. At this time, the spring 12 is stretched. After confirming that the patient's head has no tendency to tilt backward, the limiting cap 6 is pushed into the limiting groove 7, and the adjustment and locking are completed by the meshing constraint.
[0026] When it is necessary to lower the neck support height, pull out the limit cap 6 again, rotate it clockwise, the camshaft 4 will reset, the driven rod 9 will move downward under the action of the neck gravity, and at the same time the slide rod 11 will drive the limit baffle 10 away from the neck support plate 8 under the action of the spring 12 until the neck support plate 8 is lowered to the required height, and then lock the limit cap 6 again.
[0027] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
