Description

Technical Field

[0001] This utility model relates to the field of medical assistive device technology, and in particular to a head fixation device. Background Technology

[0002] Paralysis can cause certain muscles to fail to contract properly, leading to weakness or atrophy. In this situation, the muscles supporting the head become unbalanced, making it impossible for the patient to maintain a neutral head position when lying supine. Prolonged head tilting to one side can compress the jugular vein, resulting in insufficient blood return and affecting blood supply to the brain. Common symptoms of cervical spondylosis with insufficient blood supply to the brain include dizziness, headache, blurred vision, memory loss, and limb numbness. To improve this head tilting, specific braces are usually used to correct the head posture of paralyzed patients, maintaining a neutral head position and ensuring good blood circulation in the head and jugular veins. Chinese patent CN213250845U discloses a head-fixing headband that uses two straps, one on the left and one on the right, to pull the patient's forehead and chin, thereby fixing the head. However, this existing technology, due to the large distance between the traction points, applies unilateral traction to the forehead area. Especially after slight head movements, it easily causes the head to tilt in the direction of traction, resulting in an unsatisfactory effect in maintaining a neutral position. Therefore, this application proposes a head fixation device to solve the technical problem that paralyzed patients cannot maintain a neutral head position for a long time. Utility Model Content

[0003] This invention provides a head fixation device that can help paralyzed patients keep their heads in a neutral position, solving the technical problem that paralyzed patients cannot keep their heads in a neutral position for a long time and avoiding compression of the head and neck veins.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A head fixation device includes a head cushion, a forehead fixation strap, and a chin fixation strap. The two ends of the forehead fixation strap are fixedly connected to the two ends of one side of the head cushion, forming a circle around one side of the head cushion. The middle portion of the forehead fixation strap is detachably connected. The two ends of the chin fixation strap are fixedly connected to the two ends of the other side of the head cushion, forming a circle around the other side of the head cushion. The middle portion of the chin fixation strap is detachably connected. At least one limiting sleeve is provided on the outer side of the middle portion of the forehead fixation strap. A limiting hole is provided on the limiting sleeve, extending through both ends of the forehead fixation strap. A traction strap extends outward from below each end of the forehead fixation strap. One end of each traction strap is fixedly connected to the corresponding side of the head cushion. The other ends of the two traction straps cross each other, passing through the limiting hole and being tied and fixed to the bed rail on the corresponding side of the hospital bed.

[0006] Furthermore, the forehead fixing strap includes a left forehead fixing strap and a right forehead fixing strap. One end of the left forehead fixing strap and the right forehead fixing strap are respectively fixedly connected to the corresponding end of the head pad. The other ends of the left forehead fixing strap and the right forehead fixing strap are detachably attached by Velcro. The bottom surface of the limiting sleeve is sewn and fixed to the left forehead fixing strap. One end of one of the traction straps is fixedly connected to the connection between the left forehead fixing strap and the head pad, and one end of the other traction strap is fixedly connected to the connection between the right forehead fixing strap and the head pad.

[0007] Furthermore, the limiting sleeve is provided with two limiting holes arranged side by side, one end of the pulling strap passes through one of the limiting holes, and the other end of the pulling strap passes through the other limiting hole, with the two pulling straps passing through the corresponding limiting holes in opposite directions.

[0008] Furthermore, each of the traction belts is provided with a buckle in the middle, and each of the traction belts is connected or separated through the buckle.

[0009] Furthermore, the chin fixing strap includes a left chin fixing strap and a right connecting strap; one end of the left chin fixing strap and the right connecting strap are respectively fixedly connected to the two ends of the other side of the head pad, so that the chin fixing strap and the forehead fixing strap are spaced apart; the other end of the left chin fixing strap and the other end of the right connecting strap are detachably connected by Velcro.

[0010] Furthermore, the head pad has a round hole in the area directly below the forehead fixing strap.

[0011] The beneficial effects of this utility model are:

[0012] 1) This utility model places a head cushion under the patient's head, fixes the forehead fixation strap to the forehead, and places the chin fixation strap over the patient's chin. Two traction straps pass through the limiting sleeve in a forked manner. After adjusting the patient's head to a neutral position, the two traction straps are tied and fixed to the bed rail on the corresponding side of the bed. The opposing traction forces of the two traction straps can prevent the patient's head from tilting, and can keep the patient's head in a neutral position for a long time, avoiding compression of the head and neck veins and maintaining good blood circulation in the head. The limiting sleeve can ensure that the traction directions of the two traction straps are set opposite to each other and concentrated on the forehead, avoiding the traction straps from being crooked and causing the traction direction to deviate, thereby improving the effect of maintaining the patient's head in a neutral position.

[0013] 2) The left and right forehead fixation straps are detachably connected by Velcro, making it more convenient for patients to wear. The tightness can be adjusted according to the size of the patient's head, improving comfort and fit.

[0014] 3) The limiting sleeve design has two parallel limiting holes, which allows the two traction straps to fix the patient's forehead from different positions, dispersing the pressure of the traction straps on the forehead and reducing the patient's discomfort.

[0015] 4) A buckle is provided in the middle of the traction strap, which can be used to quickly separate or connect the straps. This allows for temporary loosening of the forehead and chin fixation straps to perform other temporary nursing care on the patient without having to untie the traction straps from the bed rails. When the patient needs to maintain a neutral head position again, the traction straps can be quickly reconnected using the buckle without having to tie them to the bed rails again.

[0016] 5) The round holes in the head pad have a breathable function. Attached Figure Description
