Description

neck brace

technical field

The invention relates to the technical field of neck support and nursing, in particular to a neck brace.

Background technique

The thyroid gland is located in the throat, surrounds the trachea, and the thyroid gland produces thyroid hormones that are secreted directly into the bloodstream. When necessary, thyroid hormones can increase the body's production capacity and raise body temperature, which help the body maintain body heat during cold weather. Thyroidectomy may be performed when the patient suffers from the following conditions, such as: thyroid cancer, goiter, benign thyroid nodule, thyroid cyst, etc.;

After the patient completes the resection, the doctor will place a drainage tube on the incision to remove the excess fluid. The drainage tube is usually removed after two days. When the patient has undergone thyroid surgery, he needs to recover by lying down on the pillow. Pillow supine position, long-time needle-removing supine position makes the patient’s neck hang in the air, causing the patient’s muscle fatigue and discomfort, which in turn will cause the patient’s head to move at will, affecting the patient’s postoperative drainage and wound recovery;

In the prior art, a neck support device is used to support the suspended part of the patient's neck, which is used to avoid neck muscle fatigue caused by long-term suspension, but most of the existing neck braces only play a simple supporting effect. There is a drainage tube inserted in the throat of the patient, so that the patient's neck cannot move around. If the patient's neck remains in the same position for a long time and cannot be relaxed, it will also cause pain and fatigue in the patient's neck and the release part of the neck support device. , and is not conducive to the rapid recovery of patients after surgery;

In view of the above, we provide a cervical collar to solve the above problems.

Detailed ways

The foregoing and other technical contents, features and effects of the present invention will be clearly presented in the following detailed description of the embodiments with reference to FIGS. 1 to 19. The structural contents mentioned in the following embodiments are all Reference is made to the drawings in the description.

Embodiment 1, this embodiment provides a neck brace, as shown in FIG. 1 , including a mounting frame 1, and the mounting frame 1 is arranged in a U shape, which is characterized in that, referring to FIG. 1. The upper end face is vertically slidably installed with an arc-shaped support plate 2, and the arc-shaped support plate 2 is connected with a lifting device (through the lifting device, we can adjust the vertical position of the arc-shaped support plate 2, and then adjust the vertical position of the arc-shaped support plate 2 according to the size of different patients. Differently, the distance between the neck of the patient and the bed board is different when the patient is lying flat on the pillow. We adjust the vertical height of the arc-shaped support plate 2 through the lifting device, so that the arc-shaped support plate 2 and the patient's height can be adjusted. The neck is perfectly fitted to achieve reliable support for the patient's neck). Referring to Figure 8, the lifting device includes connecting rods 5 that are respectively rotated and installed on both longitudinal sides of the arc-shaped support plate 2 and two laterally of the arc-shaped support plate 2. One side is provided with another set of connecting rods 5, the two connecting rods 5 located on the same side in the transverse direction are respectively rotated and installed with sliders 6 which are slidably installed on the mounting frame 1 in the longitudinal direction, and the two sliders 6 located on the same side in the longitudinal direction are respectively rotated and installed. The screw thread is matched with a driving screw 8, and the thread rotation direction of the driving screw 8 and the threaded matching part of the two sliders 6 is set in the opposite direction. The driving screw 8 is driven by the third motor 9. When the arc-shaped support plate needs to be adjusted When the vertical height is 2, we use the third motor controller to control the third motor 9 to start and drive the driving screw 8 to rotate, and then realize the vertical alignment of the arc-shaped support plate 2 through the sliding block 6 and the connecting rod 5 that cooperate with each other. For the adjustment of the position, as shown in FIG. 9, we have an arc-shaped hole 10 in the middle of the arc-shaped support plate 2, and two moving plates 11 are installed at horizontal intervals in the arc-shaped hole 10 (the two moving plates 11 are also set as arcs. The two arc-shaped plates cooperate with each other to completely block the arc-shaped hole 10. When we set the arc-shaped hole 10, the lateral width of the arc-shaped hole 10 is larger than that of the neck and the arc-shaped hole when the patient is lying flat. The contact width of the support plate 2, because the thickness of the human neck has a certain range, that is, when we set the width of the arc-shaped hole 10, the width is larger than the maximum neck thickness of the human neck, so that different patients use the device. , the neck will only be in contact with the two moving plates 11 but not with the arc-shaped support plate 2). Preferably, we can install soft fillers on the arc surfaces of the two moving plates 11, such as: Foam, latex and other materials enable the patient to have a better experience when supporting the patient's neck;

Referring to Fig. 2, we install supporting rods 12 on both lateral sides of the arc-shaped supporting plate 2 in a vertical sliding manner, and the moving plate 11 is slidably installed on the corresponding supporting rods 12. When the device is in use The schematic diagram is shown in Figure 1. When it is necessary to press and relax the patient's neck, at this time, we drive the supporting rod 12 to move downward through the vertical moving device of the supporting rod 12 and simultaneously drive the moving plate 11 to move down. , that is, the two moving plates 11 are moved down from the position shown in FIG. 1 to the position shown in FIG. 2 . At this time, we drive the two moving plates 11 through the moving plate 11 driving device arranged in the support rod 12 Move toward the direction away from each other, and finally move to the position shown in FIG. 3 , at this time, the two moving plates 11 are completely retracted to the bottom of the arc-shaped support plate 2;

Referring to Figure 3, when we drive the two moving plates 11 to move in opposite directions through the driving device of the moving plate 11, one of the driving devices of the moving plate 11 is driven synchronously by the transmission device of the arc-shaped lifting plate 13 connected to it. The arc-shaped lifting plate 13 moves upward, and when the two moving plates 11 are completely retracted into the arc-shaped supporting plate 2 (as shown in FIG. 3 ), the arc-shaped lifting plate 13 moves upward to the position shown in FIG. 3 , and along with the upward movement of the arc-shaped lifting plate 13, the two moving plates 11 do not hinder the upward movement of the arc-shaped lifting plate 13. When the two moving plates 11 are completely retracted into the arc-shaped supporting plate 2, the arc-shaped lifting plate We can set how much the 13 moves up, that is, set the transmission ratio through the transmission device of the arc lift plate 13, so that the arc surface of the arc lift plate 13 is the same height as the arc surface of the arc support plate 2 or Slightly lower than the arc surface of the arc support plate 2;

Referring to FIG. 12 , a plurality of arc-shaped frames 14 slidably installed along the radial direction are arranged on the arc-shaped lifting plate 13 at intervals along its arc-shaped surface, and the arc-shaped frame 14 and the arc-shaped lifting plate 13 are connected with The telescopic spring 15, as shown in FIG. 13, the traverse plate 16 is slidably installed in the arc frame 14, and a return spring 17 is connected between the traverse plate 16 and the arc frame 14 (we are in the two traverse plates. 16 The lower end face is rounded, as shown in FIG. 14 ), the arc lift plate 13 is rotatably installed with a first cam 18 corresponding to the arc frame 14 and the first cam 18 is connected with a cam drive The device, as shown in FIG. 12, in the initial state, the larger end of the first cam 18 faces the arc-shaped frame 14 and just does not contact the lower end surfaces of the two transverse plates 16. When it is necessary to press and relax the patient's neck At this time, we drive the first cam 18 to rotate through the cam drive device. With the rotation of the first cam 18, the smaller diameter end of the first cam 18 first touches the lower end surfaces of the two traverse plates 16 to round the corners and force the two The traverse plate 16 moves laterally within the arc-shaped frame 14 (ie slides away from each other and causes the return spring 17 to be compressed), which enables compression of the patient's neck along the plane of the patient's neck muscles , relax, so that under the action of the first cam 18, after the two traverse plates 16 move to the farthest distance in the arc frame 14, at this time, with the continuous rotation of the first cam 18, the arc frame 14 is driven to move upward. And the retractable spring 15 is stretched, so as to press and relax the neck muscles of the patient in the direction perpendicular to the patient's neck (refer to Fig. 15), along with the continuous rotation of the first cam 18, so that the first cam 18 continues to rotate. When the end of the cam 18 with the smaller diameter is no longer in contact with the two traverse plates 16, the two traverse plates 16 move toward each other under the action of the return spring 17 and finally move to the initial position. At the same time, the arc The shape frame 14 also moves downward under the action of the telescopic spring 15 and also moves to the initial position, at this time, a cycle of pressing and relaxing the neck muscles of the patient is completed;

Referring to Figure 18, we install a T-shaped frame 19 on the mounting frame 1 that is slidably fitted vertically with the arc-shaped lifting plate 13, and the T-shaped frame 19 is connected with a reciprocating drive device arranged on the mounting frame 1, Referring to Fig. 10, we are provided with a coaxially rotating sector gear 21 on the mounting frame 1 and driven by the first motor 20 at vertical intervals. The two sector gears 21 are respectively connected with the cam drive device and the reciprocating drive device. Matching and satisfying: when one of the sector gears 21 meshes with the corresponding cam drive device, the first motor 20 starts to drive the plurality of first cams 18 to rotate through the cam drive device and passes through the arc frame 14, the traverse plate 16 realizes the pressing and relaxing treatment of the patient's neck, so that when the sector gear 21 is separated from the cam driving device, the first cam 18 just rotates once under the action of the cam driving device and rotates to the initial position (ie, Completing a cycle of pressing and relaxing the patient’s neck), at this time, the other sector gear 21 starts to engage with the corresponding reciprocating drive device, and drives the T-shaped frame 19 on the mounting frame 1 through the reciprocating drive device. Move (the arc-shaped lifting plate 13 and the T-shaped frame 19 are installed vertically by sliding, that is, the arc-shaped lifting plate 13 is driven to move synchronously. The reason why the two are vertically slidably installed is to match the arc-shaped support plate 2 in the vertical position. height adjustment), we set that when the sector gear 21 is disengaged from the corresponding reciprocating drive device, the arc lift plate 13 is driven to move laterally a certain distance and the distance is just equal to the lateral width of the arc frame 14 That is, when the arc-shaped lifting plate 13 moves laterally with the same distance from the arc-shaped frame 14 under the action of the reciprocating drive device, it stops moving. At this time, the sector gear 21 matched with the cam drive device starts to engage with the cam drive device and drive the The plurality of first cams 18 rotate once again to achieve the pressing and relaxing treatment on the patient's neck, and repeat the above process in the future to achieve the pressing on the patient's neck;

It is worth noting here that the reciprocating driving device starts to drive the arc-shaped lifting plate 13 in the opposite direction only when the arc-shaped lifting plate 13 moves to a position close to the lateral side wall of the arc-shaped hole 10 under the drive of the sector gear 21 In the process of driving the arc-shaped lifting plate 13 to reciprocate between the lateral two side walls of the arc-shaped hole 10, the sector gear 21 and the reciprocating driving device are driven from the start of meshing to the complete disengagement. The distance that the arc-shaped lifting plate 13 moves is the distance of the arc-shaped width of one arc-shaped frame 14;

We control the first motor 20 to rotate by the corresponding angle through the first motor controller in advance, and when the first motor 20 rotates by the corresponding angle, just drive the arc lift plate 13 from the initial position (as shown in FIG. 3 , the arc lift The plate 13 is initially in the middle position of the arc-shaped hole 10) and moves to a position close to the side wall of the arc-shaped hole 10 (at this time, the arc-shaped lifting plate 13 starts to move in the opposite direction under the action of the reciprocating drive device), and the motor controls The controller is an integrated circuit that controls the motor to work according to the set direction, speed, angle and response time by actively working. We electrically connect the first motor controller with a microcontroller and when the microcontroller receives a stop command , the microcontroller controls the first motor 20 to rotate to N (N is 2, 4, 6, 8, 10....) complete the above-mentioned angles and then controls the first motor 20 to stop working, that is, the arc lift plate 13 is finally stop at the initial position;

When the pressing and relaxing of the patient's neck is completed, and the arc-shaped lifting plate 13 moves to the initial position, we drive the two moving plates 11 to move toward each other through the driving device of the moving plate 11 and make the two moving plates 11 shown in the accompanying drawings. The position shown in 3 is moved to the position shown in FIG. 2 again. During this process, one of the driving devices of the moving plate 11 drives the arc-shaped lifting plate 13 to move down to the initial position synchronously through the arc-shaped lifting plate 13 transmission device. (ie, the position shown in FIG. 2 ), at this time, we drive the two moving plates 11 to move up through the vertical moving device of the support rod 12 and realize the blocking of the arc hole 10 , as shown in FIG. 1 , can continue to achieve reliable support for the patient's neck after the compression and relaxation of the patient's neck is completed;

In this solution, when the patient's neck does not need to be pressed and loosened, we use the two moving plates 11 to achieve reliable support for the patient's neck, and when the patient's neck needs to be pressed and loosened, we will move the two The plate 11 is contracted into the arc-shaped support plate 2 and the arc-shaped lifting plate 13 is raised, which can realize the pressing and relaxing treatment of the patient's neck, which is used to relieve the fatigue of the patient's neck muscles and avoid the patient's neck being directly pressed on. The arc lift plate 13 creates indentations on the skin of the patient's neck surface, which makes the patient feel uncomfortable. When lying down, we move the neck brace to correspond with the patient's neck to achieve reliable support for the suspended position of the patient's neck, or we can also set a slide on the bed near the head of the bed and put this support on the bed. The neck brace is slidably installed in the slideway, and then we use the traditional screw drive mechanism, that is, by turning the screw to achieve the effect of driving the neck brace to move along the length of the bed, and then adjust the neck brace to the position corresponding to the patient's neck (The screw drive mechanism is a common transmission method, and will not be described in detail here).

When we drive the two moving plates through the moving plate 11 driving device When the 11 moves back and forth, the two lifting screws 24 are driven to rotate synchronously by one of the driving devices of the moving plate 11, and then the cross 23, which is threadedly installed with the two lifting screws 24, is driven vertically along the arc-shaped support plate 2.

Referring to Figure 18, the lateral sides of the support table 36 are set in a semi-circular arc shape, and the lateral sides of the lifting plate are fixed with semi-circular arc guide rails 40 that are spaced from the semi-circular arc parts of the support table 36. At the same time, the distance between the semi-circular arc guide rail 40 and the semi-circular ring parts on the lateral sides of the support table 36 is the same as the axis of the drive plate 38. The second gear 42 on the frame 1, the second gear 42 is matched with one of the sector gears 21, when the first motor 20 drives the sector gear 21 matched with the second gear 42 to mesh with the second gear 42, through the The second worm gear 41 drives the drive plate 38 to rotate, and then the drive plate 38 drives the support table 36 to move laterally through the drive hole 39 and the round rod 37. The vertical sliding is installed on the T-shaped frame 19 as a transverse part, and then the driving plate 38 drives the T-shaped frame 19 to move laterally on the mounting frame 1, thereby driving the arc-shaped lifting plate 13 to move laterally, and when the sector gear 21 and the first The second gear 42 drives the T-frame 19 to move laterally through the second worm gear 41 and the drive plate 38 from the start of engagement to the complete disengagement process. The distance is equal to the width of the arc frame 14, that is, multiple arcs each time After the shaped frame 14 presses a certain position on the patient's neck, the drive plate 38 drives the support table 36 (T-shaped frame 19 ) to move laterally under the driving of the second worm gear 41 to the width of the arc-shaped frame 14 . After an equal distance, the movement is stopped, and the pressing of the lower part of the patient's neck is achieved again through the plurality of first cams 18, and the above process is repeated to achieve all pressing and relaxation treatments on the contact parts of the patient's neck and the moving plate 11;

When we set the driving plate 38, when the upward driving hole 39 of the driving plate 38 is engaged with the round rod 37, the shaft of the driving plate 38 is in sliding fit contact with the lower end surface of the support table 36, and when the downward driving hole 39 of the driving plate 38 is in contact with the circular rod 37 When the rod 37 is engaged, the shaft of the drive plate 38 is in sliding fit contact with the upper end surface of the support table 36.

The rod 37 is engaged, and at the same time, the driving plate 38 drives the rectangular plate 35 to move in the opposite direction through the cooperation of the driving hole 39 and the round rod 37, thereby realizing the driving of the arc-shaped lifting plate 13 to move between the arc-shaped holes 10. When the arc-shaped lifting plate 13 moves to a position close to the lateral side wall of the arc-shaped hole 10, the arc-shaped lifting plate 13 is driven to move in the opposite direction.

When the support rod 12 is positioned, the chamfered part of the U-shaped frame 55 at the bottom just touches the extrusion column 67. When we need to move the support rod 12 downward, we press down the lifting rod forcefully. 54 and through the interaction between the chamfered part of the U-shaped frame 55 and the rounded part of the extrusion column 67, the extrusion column 67 is forced to shrink into the L-shaped frame 53 (at this time, the compression spring 56 is compressed and stored), and we continue to Press the lift rod 54 downward, then the inclined block 57 fixed on the cantilever below the U-shaped frame 55 touches the trapezoidal block 52 and forces the trapezoidal block 52 to move in the direction of compressing the positioning spring 7 through the interaction between the inclined surfaces , and then synchronously drives the positioning column 50 to move outward from the positioning hole 51 through the positioning rod 49;
