Technical Field

[0001] The invention relates to the technical field of medical equipment, in particular to an adjustable neck fixing device for pediatric orthopedics. Background Art

[0002] A neck immobilizer is a new type of medical device developed and researched specifically for patients with cervical spondylosis. Medical devices refer to instruments, equipment, appliances, in vitro diagnostic reagents and calibrators, materials and other similar or related items that are used directly or indirectly on the human body. Most neck immobilizers are lightweight and easy to carry. Patients can use neck immobilizers at any time and can generally adjust the traction angle and traction force by themselves. It is a medical product that is relatively simple to operate, safe, reliable and painless.

[0003] However, the existing neck fixation device is relatively rigid in its fixation method, which may cause discomfort in the patient's neck when used for a long time. Children have poor self-control and are easily irritated, so they move their necks or turn their heads, causing secondary injuries to the neck, which is not conducive to recovery.

[0004] Although the sizes of most existing neck fixing devices can be appropriately adjusted, children's necks are thinner and shorter than those of adults, so they need to be adjusted significantly when used by children. In addition, the neck is not a regular cylinder, and there are often some gaps and spaces between the device and the child's neck, making it difficult to fit the child's neck, making the device easily subjected to force and shaking, thereby affecting the neck limiting effect on the child.

[0005] In addition, some existing devices have a large neck enclosure area, which makes it impossible to maintain smooth ventilation at the patient's neck, making it easy for the neck to sweat, thereby reducing the patient's comfort.

[0006] In view of the above problems, it is urgent to carry out innovative design based on the original neck fixation device. Summary of the invention

[0025] The head limiting plate 5, the first neck ring 7 and the second neck ring 11 are all arranged in a semi-annular structure.

[0026] The fixing structure 9 includes a groove 901, a protrusion 902, a sliding rod 903, a connecting spring 904 and a slot 905. The first neck ring 7 and one end of the second neck ring 11 are provided with a groove 901, and the protrusion 902 is snap-connected in the groove 901, and the protrusion 902 is provided with a slot 905, and the sliding rod 903 is snap-connected in the slot 905, and the end of the sliding rod 903 passes through the groove 901 and the outer wall of one side of the first neck ring 7 and is nested and connected with a connecting spring 904, and the end of the connecting spring 904 is connected to the outer wall of the first neck ring 7, and the protrusion 902 is connected to the end of the movable plate 8.

[0028] The shoulder fixing frame 12 is configured as two inverted “U”-shaped structures, and the top of the “U”-shaped structure is connected to the second neck ring 11 and the plate body 1 respectively through a plate.

[0029] Working principle: According to Figure 1 As shown, firstly, the plate body 1 is attached to the back of the child user, the shoulder fixing frame 12 is mounted on the shoulders, and then the Velcro strap 13 is passed through the armpits of the arms and then fixed by the Velcro at both ends of the strap, so that the device can be quickly installed on the child user, and the installation is firm, convenient and fast;

[0030] The head limit plate 5 is moved to fit the head of the child user, driving the tooth block strip 4 to move in the cavity 2, squeezing the movable tooth plate 301 to move in the cavity 2, and the return spring 303 is compressed. The reverse thrust of the return spring 303 makes the movable tooth plate 301 close to the tooth block strip 4. At the same time, the neck of the child user is located inside the first neck ring 7 and the second neck ring 11. According to the different neck lengths of the child user, when the neck is longer, the first neck ring 7 is lifted upward to drive the tooth block plate 6 to move upward in the cavity 2, as above. In principle, when the first neck ring 7 moves to the position of the child's neck near the lower jaw, it stops moving, and the tooth blocks of the tooth plate 6 and the movable tooth plate 301 are directly in contact with each other, so as to prevent the tooth plate 6 from driving the first neck ring 7 to move downward at will, thereby achieving a certain limiting effect. Then, the child lock bolt 304 is rotated to push the movable tooth plate 301 to move in the cavity 2 and to be in close contact with the tooth bar 4 and the tooth plate 6, so as to prevent the tooth bar 4 and the tooth plate 6 from being disengaged and moving by squeezing the movable tooth plate 301 when being subjected to upward or downward force, thereby achieving a limiting effect.

[0031] By rotating the two movable plates 8, the protrusions 902 on the ends of the movable plates 8 are respectively engaged with the corresponding grooves 901 on the ends of the first neck ring 7 and the second neck ring 11. When the protrusions 902 enter the grooves 901, they contact the arc surface of the end of the slide bar 903, squeezing the slide bar 903 to move outward in the grooves 901, and the connecting spring 904 is compressed. When the protrusions 902 completely enter the grooves 901, the grooves 905 on the protrusions 902 are perpendicular to the ends of the slide bar 903, and the connecting spring 904 is freed from the restriction, pushing the ends of the slide bar 903 to engage with the grooves 905, so that the movable plates 8 are respectively engaged with the corresponding first neck ring 7 and the second neck ring 11 to complete the limit.

[0032] According to the different neck thicknesses of child users, the rotating screw 1001 pushes the connecting plate 1002 to drive the airbag 1003 to lift the neck of the user. Through the characteristics of the airbag 1003, the neck of the child is prevented from fitting too tightly and too hard during the restriction process, which may affect the smooth breathing and cause abrasions. This is the working principle of the adjustable neck fixation device for pediatric orthopedics.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
