Description

Technical Field

[0001] The present invention relates to the technical field of head fixing devices, and more specifically, to a head fixing device for examining and treating respiratory diseases. Background Art

[0002] Respiratory diseases The respiratory department mainly deals with diseases caused by the respiratory tract. During examination and treatment, depending on the patient's respiratory disease condition, the patient is required to keep his head in a fixed position with the head low in the side position or high in the supine position to avoid unconscious head shifting, which increases the difficulty of respiratory disease examination or treatment. Therefore, a fixing device is needed to fix the head during examination and treatment of respiratory diseases.

[0003] However, after the head is fixed, when it is necessary to keep the head in a specific state, it is necessary to loosen the fixation and adjust the head position. The fixing device cannot adjust the head after fixation, which may cause the head to be loosened and fixed multiple times according to the head position during use, resulting in slow head fixation during examination and treatment. In addition, the head is fixed to keep the airway in an open and fixed state to prevent the head from shifting and blocking the airway. Since the movement of the head is integrated with the shoulders of the human body, after the head is fixed, when the shoulders shift, the airway between the shoulders and the head will be blocked by the deviation of the shoulders, which may cause the head position to be invalid when the shoulders move.

The clamping mechanism 3 is provided with two, which are symmetrically distributed with the fixator 1 as the central axis. The telescopic structure 14 is provided with four, and is evenly distributed in an annular shape. The telescopic structure 14 located directly below is different from the other three. The telescopic structure 14 directly below does not have a telescopic activity effect. The length of the wrapping pad 16 is shorter at the top and longer at the bottom, which has the effect of making the wrapping pad 16 above relative to the side position when the patient lies down. The expansion plate 15 is made of aluminum alloy and has elasticity. The expansion plate 15 is divided into four parts in a ring shape, and the connection between each part adopts a limited sliding method, so that the base 5 is located on the medical bed, and the patient's head is placed on the wrapping pad 16 directly below after lying down, and the patient's shoulder is fixed by the locking mechanism 3, so that the extrusion ring 13 is rotated, so that the extrusion ring 13 drives the telescopic structure 14 to extend and retract the expansion plate 15, and then the wrapping pad 16 forms a wrapping and fixing effect on the surrounding of the head. After the wrapping is completed, the control motor 4 drives the limit rod 12 to rotate, and rotates the fixed head to avoid the need to loosen the fixation when the head needs to be offset and rotated.

[0025] Among them, the extrusion ring 13 is provided with a movable ring a1, a threaded ring a2, and a force block a3. The threaded ring a2 is embedded in the side of the movable ring a1, and the force block a3 is installed on the outside of the movable ring a1. The outside of the force block a3 is movably matched with the side of the telescopic structure 14, and the threaded ring a2 is threadedly matched with the motor 4. There are three force blocks a3, and the movable ring a1 is used as the center to form a four-equal distribution state.

[0026] The force block a3 is provided with a friction plate a31, a bending plate a32, and a connecting plate a33. The friction plate a31 is attached to the outer side of the bending plate a32, and the connecting plate a33 is embedded in the side of the bending plate a32. The connecting plate a33 and the bending plate a32 are installed on the outer side of the movable ring a1. The outer side of the bending plate a32 is movably matched with the side of the telescopic structure 14. The friction plate a31 is made of rubber and has the characteristic of large friction. The outer side of the bending plate a32 is a continuous arc structure, and the friction plate a31 It is located at the bottom end of the arc, so that when the force block a3 rotates, the curved plate a32 slides and squeezes the side of the telescopic structure 14 under the support of the connecting plate a33, so that the side of the telescopic structure 14 is blocked on the arc structure at the position of the curved plate a32. According to the rotation of the force block a3, the telescopic structure 14 is pushed outward by the curved plate a32, and when the movable ring a1 stops rotating, the friction plate a31 at the arc position outside the curved plate a32 frictionally limits the telescopic structure 14, thereby achieving the effect of pushing the telescopic structure 14 to move.

[0027] The limit rod 12 is provided with a self-rotating plate w1, an arc groove w2, a friction rod w3, an annular ring w4, and a rotating rod w5. The friction rod w3 is welded to the side of the self-rotating plate w1. The rotating rod w5 cooperates with the inner bearing of the annular ring w4. The arc groove w2 is located on the inner side of the annular ring w4. The friction rod w3 and the arc groove w2 are frictionally matched. The inner side of the self-rotating plate w1 is welded to the outer side of the rotating rod w5. The telescopic structure 14 is embedded in the outer side of the self-rotating plate w1.

The friction rod w3 is in a flat state with a gap in the middle, and the friction rod w3 is made of aluminum alloy and has a certain elastic effect. Therefore, when the rotating rod w5 rotates to drive the rotating plate w1 to rotate, the head fixed on the inner side of the expansion plate 15 is rotated and offset, and then the rotating rod w5 is limited to rotate inside the annular ring w4, and the friction rod w3 is driven to move and squeeze on the arc groove w2 inside the annular ring w4 during rotation, so that the friction rod w3 is elastically compressed inward during rotation. When the rotation stops, the friction rod w3 is engaged in the inner position of the arc groove w2, so as to fix the rotation offset and avoid instability and looseness after rotation.

[0028] The telescopic structure 14 is provided with a movable rod t1, a metal rod t2, a telescopic rod t3, and a bearing ring t4.

The movable rod t1 is limited and slidably cooperated on the inner side of the metal rod t2. The metal rod t2 is embedded in the outer side of the limit rod 12. The extrusion ring 13 cooperates with the outer side of the bearing ring t4. The outer end of the telescopic rod t3 is embedded in the inner side of the expansion plate 15. The telescopic rod t3 is fixed on the metal rod t2. The inner limit is telescopic and movable, and a spring is arranged inside the telescopic rod t3, which has a certain compression elasticity, so that the bearing ring t4 is driven by the extrusion ring 13 to expand and push outward, and then the movable rod t1 pushes the telescopic rod t3 downward on the inside of the metal rod t2, thereby increasing the diameter of the expansion plate 15 connected to the telescopic rod t3. At the same time, when pushing the bearing ring t4 and the extrusion ring 13 to block, the expansion plate 15 contracts inwardly under the reset elasticity, so that the expansion plate 15 is expanded and telescoped, and the diameter size is adjusted according to the size of the patient's head for fixing. The specific usage and function of this embodiment are as follows: In the present invention, the base 5 is located on the medical bed. After the patient lies down, the head is placed on the wrapping pad 16 directly below, and the patient's shoulders are fixed by the locking mechanism 3, so that the extrusion ring 13 is rotated, so that the extrusion ring 13 drives the telescopic structure 14 to extend and retract the expansion plate 15, and then the wrapping pad 16 forms a wrapping and fixing effect around the head. After the wrapping is completed, the computer-controlled motor 4 is used to drive the limit rod 12 to rotate, so that the rotation rod w5 rotates and drives the rotation plate w1 to rotate, and the head fixed on the inner side of the expansion plate 15 is rotated and offset, and then the rotation rod w5 is limited and rotated on the inner side of the annular ring w4, and the friction rod w3 is driven to move and squeeze on the arc groove w2 inside the annular ring w4 during rotation, so that the friction rod w3 is elastically compressed inwardly during rotation, and the friction rod w3 is locked in the inner position of the arc groove w2 when the rotation stops, so as to fix the rotation offset and avoid instability and looseness after rotation, so as to rotate the fixed head and avoid the need to loosen the head again when the head needs to be offset and rotated.

[0029] In the present invention, the computer controls the threaded ring a2 on the side of the support plate 2 to move, driving the movable ring a1 to rotate within the support plate 2, and then the force block a3 moves and squeezes the telescopic structure 14. When the force block a3 rotates, the bending plate a32 slides and squeezes the bearing ring t4 in the telescopic structure 14 under the support of the connecting plate a33, and the movable rod t1 pushes the telescopic rod t3 downward on the inner side of the metal rod t2, and contracts inward under the resetting elasticity of the expansion plate 15, so that the expansion plate 15 is expanded and retracted, and the bearing ring t4 is on the bending plate a The arc-shaped structure at the position of 32 is blocked, and according to the rotation of the force-bearing block a3, the bearing ring t4 is pushed outward by the bending plate a32, and when the movable ring a1 stops rotating, the friction plate a31 at the arc-shaped position outside the bending plate a32 performs friction limiting on the telescopic structure 14, thereby achieving the effect of pushing the telescopic structure 14 to shrink and expand outward with the limiting rod 12 as the center, thereby fixing the head of the wrapping pad 16, and then achieving fixed wrapping support according to the size of the head, and quickly fixing it by scaling to prevent the threaded movable fixation from being too slow.

The pressure plate s1 is inclined 5 degrees from the horizontal line. The extrusion plate s5 is made of sponge material and has the characteristic of large friction. After the head is fixed, the patient's shoulder is placed on the rubber pad s3 on the upper surface of the horizontal plate s4, and then the pressure plate s1 is pulled upward to make the elastic plate s2 expand and contract horizontally, so that the outer end of the pressure plate s1 forms an inclined support and fixation for the shoulder, and under the elasticity of the elastic plate s2, the extrusion plate s5 presses downward and rubs to fix the shoulder on the surface of the rubber pad s3, so as to realize mutual support and fixation of the shoulder and the head, and prevent the shoulder movement from driving the head out of the limited fixed state of the human body.

There are two spring rods s22, and the elastic forces of the two spring rods s22 are consistent. The two spring rods s22 are both vertically on the same plane, thereby pulling the moving rod s21 to stretch the spring rod s22 in the limiting plate s23. Under the elastic force of the spring rod s22, the moving rod s21 generates an elastic force downward, which drives the pressure plate s1 to generate a downward extrusion force, and the two spring rods s22 maintain consistent elasticity, ensuring that the downward elastic force of the elastic plate s2 remains horizontal and uniform to support the shoulder, and prevents the shoulder from easily escaping from the fixation of the locking mechanism 3 under the elastic force of the spring rod s22. The specific usage and function of this embodiment are as follows: In the present invention, after the head is fixed, the patient's shoulders are placed on the rubber pad s3 on the upper surface of the horizontal plate s4, and then the pressure plate s1 is pulled upward, thereby driving the moving rod s21 to move upward, so that the spring rod s22 is stretched in the limit plate s23, and the moving rod s21 generates an elastic force downward under the elastic force of the spring rod s22, driving the pressure plate s1 to generate a downward extrusion force, and the two spring rods s22 maintain consistent elasticity, ensuring that the downward elastic force of the elastic plate s2 remains horizontal and uniform to support the shoulder, so that the outer end of the pressure plate s1 forms an inclined support and fixation for the shoulder, and under the elasticity of the elastic plate s2, the extrusion plate s5 presses downward and rubs to fix the shoulder to the surface of the rubber pad s3, so as to achieve mutual support and fixation of the shoulder and the head, and prevent the shoulder movement from driving the head out of the limited fixed state of the human body.
