Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a neck fixation device. Background Technology

[0002] Neck immobilizers provide fixation and support for patients with cervical spine fractures and provide cushioning during transport. They can prevent the injury from worsening due to movement of the fracture site during transport, effectively prevent secondary injuries caused by improper on-site treatment, and play an important protective role in preventing the fractured bone fragments from piercing muscles, nerves, blood vessels or organs, thus preventing pain, bleeding or even shock.

[0003] A search revealed a patent with application number 202323072572.4, which discloses a neck fixation device for emergency departments, relating to the field of medical devices. The device includes a fixation bracket with a support plate fixedly connected to the center of one side for patient support. This invention, through the arrangement of a rhomboid bracket, concave inner columns, and concave outer columns, allows the user to lean against the support plate. Medical personnel adjust the concave inner columns on both sides, causing them to extend the neck support bracket to a suitable position, improving adaptability to different users and ensuring it supports the user's neck, preventing uncontrolled movement. Subsequently, a pressure rod is used to rotate a pressure cylinder eccentrically via a first shaft located away from the center. This rotation of the pressure cylinder fixes the fixing block inside the concave inner column, thus fixing the concave inner column to the inner wall of the concave outer column, thereby securing the neck support bracket. This makes fixing and disassembly relatively convenient. However, the aforementioned patent has the following shortcomings: the positions of the two neck support brackets need to be adjusted separately during use, which is inconvenient, and it cannot fix the patient's head during use. Therefore, this invention proposes a new solution. Utility Model Content

[0031] like Figures 1-6As shown, this embodiment proposes a neck fixation device, including a bidirectional drive mechanism 1 and a rotating handle 4. A first connecting rod 7 and a second connecting rod 8 are symmetrically mounted on the bidirectional drive mechanism 1. A first neck support frame 2 and a second neck support frame 3 are respectively mounted on the first connecting rod 7 and the second connecting rod 8. A first screw 14 is threaded onto both the first connecting rod 7 and the second connecting rod 8. A bottom support pad 13 is installed at the top center of the bidirectional drive mechanism 1. By configuring the bidirectional drive mechanism 1, the rotating handle 4, the first connecting rod 7, and the second connecting rod 8, the bidirectional drive mechanism 1 can be activated by rotating the rotating handle 4 during use, causing the first connecting rod 7 and the second connecting rod 8 to move towards each other, thereby simultaneously directing the first neck support frame 2 and the second neck support frame 3 toward the patient. The neck movement is controlled without the need to adjust the positions of the first neck support frame 2 and the second neck support frame 3 separately, making it more convenient and faster to use and effectively improving the speed of fixation. A mounting frame 11 is installed on the back of the bidirectional drive mechanism 1. The end of the mounting frame 11 away from the bidirectional drive mechanism 1 is connected to a head support pad 6. The two side walls of the head support pad 6 are equipped with first fixing straps 9, and each of the two first fixing straps 9 is provided with a first Velcro 10. By setting the head support pad 6, the first fixing straps 9 and the first Velcro 10, the patient's head can be supported by the head support pad 6 during use. At the same time, the patient's head can be fixed by the first fixing straps 9 and the first Velcro 10, thereby preventing the head from shaking and pulling on the neck, and better protecting the patient.

[0032] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, a cushion 5 is further installed on the front of the bidirectional drive mechanism 1, and anti-slip pads 12 are installed on the bottom of both the bidirectional drive mechanism 1 and the cushion 5. It should be noted that the cushion 5 provides convenient support for the patient's back, and the anti-slip pads 12 prevent the bidirectional drive mechanism 1 and the cushion 5 from sliding on the stretcher or hospital bed.

[0033] like Figure 1 , Figure 2 and Figure 5 As shown, in a preferred embodiment, based on the above method, the cushion 5 further includes a base plate 501 fixedly connected to the bidirectional drive mechanism 1, and a soft pad 502 is installed on the top of the base plate 501. It should be noted that the base plate 501 facilitates the installation of the pad 502, and the soft pad 502 improves the patient's comfort during use.

[0034] like Figure 1 , Figure 2 and Figure 5As shown, in a preferred embodiment, based on the above method, a second fixing strap 503 is fixedly connected to both side walls of the base plate 501, and a second hook and loop fastener 504 is provided on each of the two second fixing straps 503. It should be noted that, in use, the two second fixing straps 503 and the second hook and loop fastener 504 can fix the patient's torso from the chest position, so that the movement of the torso will affect the neck, thus better protecting the patient.

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, in a preferred embodiment, based on the above method, the bidirectional drive mechanism 1 further includes a housing 101. A bidirectional lead screw 104 is rotatably mounted inside the housing 101. A through groove 102 is provided on the top of the housing 101 to cooperate with the first connecting rod 7 and the second connecting rod 8. One end of the bidirectional lead screw 104 is connected to a rotating handle 4 located on the outside of the housing 101. Two sliders 103 are provided on the bidirectional lead screw 104, which respectively cooperate with the first connecting rod 7 and the second connecting rod 8. It should be noted that, during use, rotating the rotating handle 4 can drive the two sliders 103 on the bidirectional lead screw 104 to move towards or away from each other, thereby driving the first connecting rod 7 and the second connecting rod 8 to move, completing the simultaneous adjustment of the positions of the first neck support frame 2 and the second neck support frame 3.

[0036] like Figure 3 and Figure 4 As shown, in a preferred embodiment, based on the above method, a sliding rail 105 is further fixedly connected to the back of the housing 101, and multiple screw holes 106 located on both sides of the sliding rail 105 are provided on the back of the housing 101. It should be noted that, through the setting of the sliding rail 105 and the screw holes 106, the height position of the mounting bracket 11 can be adjusted in conjunction with the second screw 112, thereby adjusting the height position of the head support pad 6, making it convenient for different patients to use.

[0037] Such as 2 and Figure 6As shown, in a preferred embodiment, based on the above method, the mounting bracket 11 further includes a sliding sleeve 111 and a sliding rod 115 slidably connected thereto. The sliding sleeve 111 has a groove 113 that mates with the sliding track 105. A second screw 112, which mates with a screw hole 106, is threaded onto the sliding sleeve 111. A third screw 114, which mates with the sliding rod 115, is threaded onto the bottom of the sliding sleeve 111. It should be noted that after the height of the sliding sleeve 111 is adjusted, the second screw 112 can be screwed into the corresponding screw hole 106 to fix the position of the sliding sleeve 111. During use, the sliding rod 115 can be pulled out or inserted from inside the sliding sleeve 111, thus facilitating the adjustment of the position of the head support pad 6 according to the patient's condition. After adjustment, the third screw 114 is tightened to hold the sliding rod 115 in place, thereby fixing the position of the sliding rod 115.

[0038] Specifically, the working principle of this neck fixation device is as follows: During use, the bidirectional drive mechanism 1 is activated by rotating the handle 4, thereby driving the first connecting rod 7 and the second connecting rod 8 to move towards each other. This allows the patient's neck to be clamped and fixed by the first neck support frame 2 and the second neck support frame 3. Then, the patient's head is supported by the head support pad 6. The patient's head is then fixed to the head support pad 6 by the first fixing strap 9 and the first Velcro 10. After the fixation is completed, the two second fixing straps 503 are wrapped around the patient's chest and connected by the second Velcro 504, thereby fixing the patient's torso.
