Description

Technical Field

[0001] The invention relates to the technical field of emergency departments, and in particular to a neck fixing device for emergency departments. Background Art

[0002] As an important device in the field of orthopedics and emergency medicine, the technical evolution of the neck immobilizer is closely related to the research on cervical biomechanics, the progress of material science and clinical needs. The neck immobilizer limits abnormal neck movement through physical support to prevent cervical fractures, dislocations or secondary injuries caused by improper movements of patients after surgery. In emergency scenarios (such as traffic accidents and falls from heights), it is used to temporarily fix the cervical spine to reduce the risk of further damage to the spinal cord or nerves.

[0003] Existing neck fixators focus more on fixing the patient's head in a normal anatomical position, but in some emergency scenarios, existing neck fixators cannot be directly applied. For example, when a patient with ankylosing spondylitis suffers a cervical fracture, the original deformity angle needs to be fixed, and forced correction that causes iatrogenic fractures should be avoided. There are also other situations where the anatomical position cannot be restored immediately after a fracture. Summary of the invention

DETAILED DESCRIPTION

[0028] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0029] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the present invention belongs.

[0030] like Figure 1-6 As shown, this embodiment provides an emergency department neck fixation device for fixing the neck and head of a human body, including a support frame, a mandibular support part 300, a side support assembly and a back head support part 400. The bottom of the support frame is constructed in a shape matching the human shoulder, and the internal structure has a space for accommodating the neck. In order to facilitate wearing, the support frame is divided into two parts, so that the support frame can be rotated and opened, and closed and fixed after wearing. The mandibular support part 300 is adjustable and arranged on the front side of the support frame; the side support assembly includes a first side support 500 and a second side support 600 corresponding to the two sides of the neck. The two side supports have the same structure. The first side support 500 and the second side support 600 can be independently raised and lowered and adjusted and arranged on the left and right sides of the support frame. Side adjustment parts for driving the first side support 500 and the second side support 600 are also provided on both sides of the support frame. In other words, the first side support 500 and the second side support 600 can be adjusted to different heights, for example, the first side support 500 is adjusted to be higher than the second side support 600, so that the fixed head is biased toward the second side support 600. The back head supporting portion 400 is adjustably arranged at the rear side of the supporting frame.

[0031] The first side support 500 and the second side support 600 can be adjusted independently to fix the patient in the optimal position, especially when the patient suffers a neck injury due to an emergency and the patient's head cannot be restored to the anatomical position in this case. The first side support 500 and the second side support 600 can be independently adjusted to fix the patient's neck and head in the current position to avoid secondary injury.

[0032] In some embodiments, the top surface of the first side support 500 is provided with a flexible layer 511, the top surface of the second side support 600 is provided with a flexible layer 611, the bottom of the first side support 500 and the second side support 600 is also provided with a docking portion 630 connected to the side adjustment member, and the inner wall of the side of the support frame is provided with a slide groove 201 matching the docking portion 630. The flexible layer (511, 611) can increase the comfort of the patient, and the flexible layer (511, 611) is directly connected to both sides of the patient's head, including both sides of the mandible. The docking portion 630 can slide in the slide groove 201, and can raise the side support when sliding upward, and can lower the side support when sliding downward. When the patient's neck and head are in a normal anatomical position, the first side support 500 and the second side support 600 are adjusted to be flush and support the patient's head. When the patient's head deviates to one side and cannot return to its original position, the side support corresponding to the side where the patient's head deviates is lowered to press against the patient's face or side of the mandible, and the corresponding side support on the other side is raised to press against the patient's face or head to fix the patient's head and prevent it from swinging left and right and causing secondary injury.

[0033] In some embodiments, the side adjustment member includes a screw rod 640, which penetrates the support frame and is rotatably arranged in the slide groove 201, a slider 631 screwed to the screw rod 640 is arranged on the docking portion 630, and a knob 650 connected to the screw rod 640 is arranged on the outside of the support frame. The screw rod 640 is arranged in a roughly vertical state, which saves more horizontal space. The openings on the support frame corresponding to the screw rod 640 are distributed below the support frame, so that the screw rod 640 can extend from the bottom of the support frame to the top, which just corresponds to the up and down movement of the docking portion 630. Specifically, a driven gear 641 is arranged on the screw rod 640 at a position corresponding to the knob 650, and the outer periphery of the knob 650 is meshed with the driven gear 641 to drive the screw rod 640. The knob 650 is rotatably arranged on the support frame, and the axial direction of the knob 650 is parallel to the axial direction of the screw rod 640. In order to lock the knob 650 so that it remains stationary after being adjusted to the right position, a claw is provided on the outside of the support frame corresponding to the outer periphery of the knob 650. The claw is movably provided on the support frame and is pushed by a third spring to lock the knob 650. When adjustment is required, the knob 650 can be turned by manually pushing the claw away.

[0034] In some embodiments, the mandibular support part 300 and the back head support part 400 are also adjusted by the lifting and lowering adjustment mechanism, which includes an external adjustment button 310. A lifting rod that docks with the external adjustment button 310 is provided in the support frame, and the lifting rod is provided with an external thread. The mandibular support part 300 and the back head support part 400 are respectively provided with sliding blocks corresponding to the lifting rod, and the sliding blocks are provided with internal thread holes. The inner wall of the support frame is also provided with a sliding groove for slidingly assembling the sliding block. The mandibular support part 300 or the back head support part 400 can be raised or lowered by turning the external adjustment button 310.

[0035] In some embodiments, the flexible layer 511 is fixed on a support sheet 510, and an adaptive support member is further arranged between the support sheet 510 and the top of the corresponding side bracket. The adaptive support member includes a guide column 512 and an elastic member. The top of the side bracket is provided with a socket 501 matching the guide column 512. The elastic member includes a first spring 520 and a docking rod 521. The first spring 520 is arranged on the side bracket and extends toward the socket 501. The docking rod 521 is fixed to the end of the first spring 520 and radially extends into the socket 501. A protrusion 513 is arranged on one side of the guide column 512 corresponding to the docking rod 521. When the flexible layer 511 is compressed, it drives the guide column 512 to press down in the socket 501 and pushes the docking rod 521 to compress the first spring 520. The first spring 520 is arranged on the side bracket in a substantially horizontal state, so that the movement direction and movement space of the first spring 520 are independent of the guide column 512, and the movement space of the guide column 512 is not increased. In this way, the thickness of the flexible layer 511 and the adaptive support member is smaller. The adaptive support member is provided so that the patient has a small range of movement space, and the flexible layer 511 can always be close to the patient's head to maintain the support state. The socket 501 on the side support can be provided by a hollow cylinder, the hollow cylinder extends upward from the top of the side support, and the guide column 512 is inserted into the hollow cylinder. In order to prevent the guide column 512 from detaching from the hollow cylinder, a limiting edge is provided at the end of the guide column 512 extending into the cylinder, and the limiting edge extends radially outward from the outer periphery of the guide column 512, and a blocking edge is provided on the inner edge of the top of the cylinder to block the limiting edge, and the blocking edge extends radially inward from the inner edge of the top of the cylinder. In order to ensure that the guide column 512 moves normally in the cylinder, the inner diameter of the inner edge is limited to be larger than the outer diameter of the cylinder. The socket 501 on the side support can also be formed by a downward depression on the top of the side support. In this case, the adaptive support member needs to be buried inside the side support. Specifically, a mounting channel 502 connected to the socket 501 can be opened inside the side support, and the first spring 520 can be arranged in the mounting channel 502.

[0036] Furthermore, in order to increase the stability of the flexible layer 511 moving up and down, there are preferably 2-3 guide posts 512, which are arranged at intervals along the length direction of the flexible layer 511. Correspondingly, the number and position of the jacks 501 on the side bracket correspond to the guide posts 512 one by one.

[0037] In some embodiments, the side of the protrusion 513 facing the docking rod 521 is provided with an inclined surface, and the end of the docking rod 521 that contacts the inclined surface is provided with a ball 522. When the flexible layer 511 is compressed and drives the guide post 512 to move toward the socket 501, the inclined surface of the protrusion 513 can gradually squeeze the docking rod 521, and the docking rod 521 reacts the elastic force of the first spring 520 on the protrusion 513, so that the guide post 512 obtains a force that pushes it outside the socket 501, thereby making the support of the flexible layer 511 stronger. Through the contact between the ball 522 and the inclined surface, it can be prevented that the docking rod 521 scratches the protrusion 513.

[0038] In some embodiments, the support frame includes a first frame 100 and a second frame 200, and the first frame 100 and the second frame 200 are enclosed to form an enclosed space surrounding the neck. In order to avoid the side support member, the two contact parts of the first frame 100 and the second frame 200 are respectively arranged near the front and rear of the support frame. In other words, the contact parts of the first frame 100 and the second frame 200, one is located at the transition part of the side and the front of the support frame, and the other is located at the transition part of the rear and the side of the support frame. The first frame 100 and the second frame 200 second contact part 20 are connected by a flexible member, so that the first frame 100 and the second frame 200 can be opened around the flexible member. The first contact part 10 of the first frame 100 and the second frame 200 is connected by a locking member, and after the support frame is worn on the patient's neck, it is fixed by the locking member.

[0039] In some embodiments, the flexible member can be a nylon belt, and the nylon belt has multiple roots, and the multiple nylon belts are distributed in the first frame 100 and the second frame 200 in the second contact position 20 in sequence. The two ends of the nylon belt are respectively connected to the outer walls of the first frame 100 and the second frame 200. The locking member includes a fixing belt 700 and an adjusting portion, one end of the fixing belt 700 is fixed on the first frame 100 or the second frame 200, and the adjusting portion is fixed to the other frame corresponding to the fixing belt 700. When performing the locking operation, the movable end of the fixing belt 700 is inserted into the adjusting portion, and the connection between the adjusting portion and the fixing belt 700 realizes the locking of the first frame 100 and the second frame 200. The adjusting portion includes a shell 800, and an adjusting button 810 is rotatably provided on the shell 800, and an adjusting gear 820 is provided in the shell 800, and the adjusting button 810 and the adjusting gear 820 are connected to drive the adjusting gear 820 to rotate. The housing 800 is also provided with through fixing holes 801 on both sides. The fixing belt 700 is inserted into the fixing hole 801 on one side of the housing 800 and is passed out from the fixing hole 801 on the other side. The fixing belt 700 is also provided with a rack meshing with the adjustment gear 820. Further, the rack is preferably fixed to the outside of the fixing belt 700 and arranged in the direction of the adjustment gear 820. The adjustment gear 820 includes a rotating shaft 823. The rotating shaft 823 corresponding to the upper and lower surfaces of the adjustment gear 820 in the housing 800 is also provided with a rotation limiter. The rotation limiter includes a rotation hole close to the bottom surface of the adjustment gear 820 and located on the inner bottom surface of the housing 800, and also includes a mounting plate 803 close to the top surface of the adjustment gear 820. The mounting plate 803 is provided with a hole for the rotating shaft 823 to pass through. The mounting plate 803 and the inner bottom surface of the housing 800 define a space for accommodating the adjustment gear 820.

[0040] Furthermore, an open notch is provided in the middle of the fixing belt 700 along its length, a rack is arranged on one side of the edge of the notch, and the adjustment gear 820 is located in the notch and meshes with the rack. This arrangement allows the adjustment button 810 to be located closer to the center line of the fixing belt 700. The rack is closer to the center of the fixing belt 700, and the torque generated in the width direction of the fixing belt 700 is smaller, and the deformation of the fixing belt 700 in the width direction is smaller, making the meshing more stable.

[0041] In some embodiments, a limiting mechanism is also provided between the adjusting button 810 and the housing 800. During normal adjustment, the adjusting button 810 can normally tighten or loosen the fixing belt 700. When the limiting mechanism intervenes, the adjusting button 810 and the housing 800 are in a fixed state, so that the adjusting button 810 can no longer rotate, and the fixing belt 700 can remain in the adjusted position without changing. Ensure stability after adjustment. Specifically, the limiting mechanism includes an inner gear ring 802 on the housing 800, the inner gear ring 802 is arranged around the adjusting button 810, and an outer tooth 812 meshing with the inner gear ring 802 is constructed on the outer periphery of the adjusting button 810. After the outer teeth 812 of the adjusting button 810 are meshed with the inner gear ring 802, the adjusting button 810 is limited and cannot rotate. Therefore, when the fixing belt 700 needs to be adjusted, the adjusting button 810 and the inner gear ring 802 need to be disengaged from the meshing state. To this end, the adjusting button 810 is set to be in a state of axial movement and non-disengagement with the adjusting gear 820 and circumferential fixation.

[0042] Further, the adjusting button 810 is configured to be inserted into the inner gear ring 802 to achieve fixation when there is no external force interference, and the adjusting button 810 is released from the locked state by external force when rotation adjustment is required. Specifically, an assembly hole 815 is constructed at the center of the adjusting button 810, and the cross section of the assembly hole 815 is a polygonal structure. The upper part of the adjusting gear 820 is provided with a docking section 821 that matches the assembly hole 815, and the cross section of the docking section 821 matches that of the assembly hole 815. A second spring 814 is also provided between the docking section 821 and the adjusting button 810, and the second spring 814 pushes the adjusting button 810 to the locked state. When unlocking is required, the adjusting button 810 is pressed axially, so that the adjusting button 810 compresses the second spring 814 and moves toward the direction close to the adjusting gear 820, so that the outer teeth 812 on the adjusting button 810 are separated from the inner gear ring 802 in the axial direction and unlocked. In order to ensure that the adjusting button 810 and the docking section 821 are in a state where they will not be completely separated, a radially outwardly extending limit block 822 is provided on the docking section 821, and a limit groove 813 for accommodating the limit block 822 is provided on the inner wall of the assembly hole 815. Further, there are two limit blocks 822 and two limit grooves 813, and the two limit blocks 822 are symmetrically arranged along the axial section of the docking section 821, and the two limit grooves 813 correspond to the limit blocks 822 one by one. Preferably, the second spring 814 can be arranged between the top of the docking section 821 and the inner top of the assembly hole 815. In addition, it is also necessary to ensure that after the adjusting button 810 is pressed, the position of the adjusting button 810 corresponding to the inner gear ring 802 cannot be connected with the inner gear ring 802 to avoid interference. To this end, a neck section 811 is also provided between the outer teeth 812 and the outermost end of the adjusting button 810, and the outer diameter of the neck section 811 is smaller than the inner diameter of the inner gear ring 802. The length of the neck section 811 is slightly greater than the thickness of the inner gear ring 802. It is understandable that the above-mentioned limiting mechanism can also be provided between the outer adjustment button 310 for adjusting the mandibular support part 300 and the back head support part 400 and the support frame.

[0043] Furthermore, a accommodating space is provided below the axial direction of the inner gear ring 802 in the outer shell 800, and the accommodating space is used to accommodate the outer gear 812 after it is lowered. The accommodating space can ensure that the adjusting button 810 can be lowered normally and can rotate normally after it is lowered.
