Description

Technical Field

[0001] The invention relates to the field of wheelchair neck supports, in particular to a neck support for a wheelchair. Background Art

[0002] One day after cervical spine surgery, patients need to sit in a wheelchair for examination or activities outside, which requires the neck to be braked and the neck cannot be flexed, extended or rotated. Currently, most wheelchairs on the market do not have the function of neck support and lack effective protection for the cervical spine, causing the patient's head and neck to lose stability, which is not conducive to recovery. Therefore, how to add a neck support mechanism to the wheelchair is an urgent problem that technicians in this field need to solve. Summary of the invention

[0003] The object of the present invention is to provide a neck support for a wheelchair to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: A wheelchair neck support device, comprising an inverted "U"-shaped splint sleeved on the wheelchair backrest, a support plate is provided at the upper end of the splint, and a support plate for supporting the neck is connected to the upper end of the support plate through a telescopic mechanism, and the support plate is in an arc shape parallel to the axis of the neck. The support plate supports the neck and is in a "C" shape toward the face, and at the same time, has an upper and lower width to ensure stability.

[0005] Preferably, the telescopic mechanism includes a sleeve plate that is adapted to be sleeved on the support plate, and the sleeve plate is threadedly connected with a fastening knob whose inner end presses against the support plate. By loosening the fastening knob, the support plate can be pulled up and down, thereby changing the support height of the neck to accommodate patients of different heights.

[0006] Preferably, it also includes an inflatable mechanism arranged at the backrest of the wheelchair to support the waist, and the inflatable mechanism is connected to a piston mechanism arranged between the support plate and the splint. When the inflatable mechanism is squeezed, the piston mechanism can drive the support plate to rise to support the head. When the patient leans forward, the back will be squeezed backward and the inflatable mechanism will inflate, thereby driving the support plate to rise through the piston mechanism to support the patient's head and prevent it from leaning forward and moving downward.

[0007] Preferably, the inflation mechanism includes an airbag cushion and an air pipe connected to the airbag cushion, and the air pipe is connected to the piston mechanism. The airbag cushion is flat, similar to a pillow, and the size can be set as needed.

[0008] Preferably, the piston mechanism comprises a plate-shaped piston cylinder fixed to the upper end of the splint, and the support plate extends downward to form a piston part inserted into the piston cylinder, and a sealing ring is arranged at the lower end of the piston part, and the trachea is connected to the bottom of the inner cavity of the piston cylinder. The piston part can be widened and thickened as needed, inserted into the piston cylinder, and rises when the trachea is inflated, driving the support plate to move up, thereby passing through the mandible, that is, the lower part of the cheek, which is convex and easy to lift, thereby preventing the patient from continuing to lean forward and move downward. At the same time, the support force increases, the patient will feel great pressure, sit up straight, and reduce the support force of the support plate on the mandible, so as to maintain comfort. Here, the initial support force can be very small or zero, and can be adjusted by tightening the knob.

[0009] Preferably, tough support blocks for supporting the mandible are respectively provided at the two ends of the support plate, and the support blocks are against the lower side of the mandible, so that the support blocks can support the mandible more easily and achieve better effect.

[0010] Preferably, the support block is an air bag and is in an arc shape that fits the mandible, which is more comfortable.

[0011] Preferably, the support block is connected to a ventilated branch pipe, and the other end of the branch pipe is connected to the bottom of the inner cavity of the piston cylinder. When the airbag cushion is squeezed, not only the piston part drives the support plate to rise, but also drives the support block to expand, thereby increasing the clamping force to prevent forward slipping, and also increasing the hardness, thereby improving the upward supporting force and effect.

[0012] Preferably, the support plate is made of elastic plastic so that the support block fits the mandible, so that the support block fits better, and the support plate can be semicircular.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. The splint can be directly installed on the wheelchair backrest to achieve fixation and easy installation. The support plate can support the neck from the back and limit tilting to both sides. By tightening the knob, the support plate can be telescopically adjusted to change the support position of the support plate to cope with patients of different heights; 2. The support plate is semicircular and supported on the lower side of the mandible. When the patient leans forward, the back will squeeze the airbag cushion, and the gas will be filled into the piston cylinder through the trachea, thereby pushing the inner piston part up. The piston part drives the support plate, support plate and sleeve plate to rise, and support the patient's mandible, thereby preventing the patient from leaning forward or lowering his head; 3. The support block can better support the lower side of the mandible, and when the patient leans forward, it can be inflated to press the mandible inward and upward, thereby lifting the head upward and avoiding leaning forward.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] Example 1 See also Figures 1 to 3 The present invention provides a technical solution for a wheelchair neck supporter: a wheelchair neck supporter, comprising an inverted "U"-shaped splint 1 sleeved on the wheelchair backrest, a support plate 2 is provided at the upper end of the splint 1, and a support plate 3 for supporting the neck is connected to the upper end of the support plate 2 through a telescopic mechanism, and the support plate 3 is in an arc shape parallel to the axis of the neck. The support plate 3 supports the neck and is in a "C" shape toward the face, and at the same time, has an upper and lower width to ensure stability.

[0018] The telescopic mechanism includes a sleeve plate 4 which is sleeved on the supporting plate 2 and is matched with the supporting plate 2, and a fastening knob 5 which is threadedly connected to the sleeve plate 4 and whose inner end is pressed against the supporting plate 2. By loosening the fastening knob 5, the supporting plate 2 can be pulled up and down, thereby changing the supporting height for the neck to adapt to patients of different heights. The sleeve plate 4 can also protrude one end toward the patient's head to facilitate better support of the support plate 3.

[0019] Example 2 like Figures 4 to 6As shown, based on Example 1, as a preferred embodiment, it also includes an inflatable mechanism arranged at the backrest of the wheelchair to support the waist, and the inflatable mechanism is connected to a piston mechanism arranged between the support plate 2 and the splint 1. When the inflatable mechanism is squeezed, the piston mechanism can drive the support plate 3 to rise to support the head. When the patient leans forward, the back will be squeezed backward, and the inflatable mechanism will be inflated, thereby driving the support plate 3 to rise through the piston mechanism to support the patient's head and avoid leaning forward and moving down. The inflatable mechanism includes an airbag cushion 6 and an air pipe 7 connected to the airbag cushion 6, and the air pipe 7 is connected to the piston mechanism. The airbag cushion 6 is flat, similar to a pillow, and the size can be set as needed.

[0020] The piston mechanism includes a plate-shaped piston cylinder 8 fixed to the upper end of the clamp plate 1, and the support plate 2 extends downward to form a piston part 9 inserted into the piston cylinder 8, and a sealing ring is provided at the lower end of the piston part 9, and the air pipe 7 is connected to the bottom of the inner cavity of the piston cylinder 8. The piston part 9 can be widened and thickened as needed, inserted into the piston cylinder 8, and rises when the air pipe 7 is inflated, driving the support plate 3 to move up, thereby passing through the mandible, that is, the lower part of the cheek, which is convex and easy to lift, thereby preventing the patient from continuing to lean forward and move down. At the same time, the support force increases, the patient will feel great pressure, and will sit upright, reducing the support force of the support plate 3 on the mandible, so as to maintain comfort. Here, the initial support force can be very small or zero, which can be adjusted by tightening the knob 5.

[0021] Preferably, the two ends of the support plate 3 are respectively provided with a tough support block 10 for supporting the mandible, and the support block 10 is against the lower side of the mandible, so that the support block 10 can support the mandible more easily and the effect is better. Preferably, the support block 10 can be an air bag, and is in an arc shape that fits the mandible, which is more comfortable. Preferably, the support block 10 is connected with a ventilated branch pipe 11, and the other end of the branch pipe 11 is connected to the bottom of the inner cavity of the piston cylinder 8. When the airbag cushion 6 is squeezed, not only the piston part 9 drives the support plate 3 to rise, but also drives the support block 10 to expand, increases the clamping force, avoids slipping forward, and also increases the hardness, improves the upward support force and effect. The support plate 3 is an elastic plastic so that the support block 10 fits the mandible, so that the fit of the support block 10 is better, and the support plate 3 can be semicircular.

[0022] Working principle: The splint 1 can be directly installed on the wheelchair backrest to achieve fixation and easy installation. The support plate 3 can support the neck from the back and limit tilting to both sides. By tightening the knob 5, the support plate 2 can be telescopically adjusted to change the support position of the support plate 3 to cope with patients of different heights. The support plate 3 is semicircular and supported on the lower side of the mandible. When the patient leans forward, the back will squeeze the airbag cushion 6, and the gas will be filled into the piston cylinder 8 through the air pipe 7, thereby pushing the inner piston part 9 to rise. The piston part 9 drives the support plate 2, the support plate 3 and the sleeve plate 4 to rise, and support the patient's mandible, thereby preventing the patient from leaning forward or lowering his head; The support block 10 can better support the lower side of the mandible, and when the patient leans forward, it can be inflated to press the mandible inwardly and upwardly, thereby lifting the head upward to avoid leaning forward.
