[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] The embodiment of the invention discloses an adjustable head fixing frame for eye diagnosis and treatment of infants and young children.

[0033] Reference Figure 1-6 , an adjustable head fixing frame for eye diagnosis and treatment of infants and young children, comprising a head support pad 1, a U-shaped fixing rod 4 is movably sleeved on the outer sides of both ends of the head support pad 1, and sliders 42 are fixedly installed on the inner walls of both ends of the two U-shaped fixing rods 4, and adjustment grooves 5 are opened on both sides of both ends of the head support pad 1, and the sliders 42 at both ends of the U-shaped fixing rod 4 are spliced ​​and slid in the adjustment grooves 5 at both ends of the corresponding head support pad 1, so that the U-shaped fixing rod 4 can stably slide on the outside of the head support pad 1;

[0034] Two sets of head fixing components 7 are movably sleeved on the outer sides of the two U-shaped fixing rods 4, and angle adjustment components 3 are provided on the other two end surfaces of the head support pad 1, and a support plate 2 is fixedly installed on the bottom of the angle adjustment component 3; the medical staff adjusts the two sets of head fixing components 7 on the outer sides of the U-shaped fixing rods 4 according to the size of the infant's head, so that the two sets of head fixing components 7 match the position of the infant's head, so that the sliding U-shaped fixing rods 4 can drive the head fixing components 7 to fix the infant's head;

[0035] The head fixing assembly 7 includes a sliding frame 71, which is slidably sleeved on the outside of the U-shaped fixing rod 4. An adjusting frame 73 is fixedly installed on the surface of the sliding frame 71. A threaded rod 75 is rotatably installed on the inner wall of the adjusting frame 73. The threaded rod 75 rotates through the adjusting frame 73 and is fixedly connected to the handle A74. A guide block 76 is threadedly sleeved on the outer side of the threaded rod 75. One side of the guide block 76 away from the sliding frame 71 is horizontally movably connected to the fixing plate 711, and an airbag cushion 712 is adhered to the other side of the fixing plate 711.

[0036] During specific use, after the two sets of head fixing components 7 are matched with the position of the infant's head, the handle A74 is rotated, and the handle A74 drives the threaded rod 75 to rotate, thereby driving the fixing plate 711 to move up and down, so that the horizontal position of the fixing plate 711 is aligned with the infant's head, and finally the U-shaped fixing rod 4 is moved to drive the head fixing component 7 to fix the infant's head; since the fixing plate 711 is rotatably connected to the rotating shaft frame 79 through the arc-shaped connecting block 710, the fixing plate 711 can rotate freely in the horizontal direction. This feature ensures that the airbag cushion 712 on the surface of the fixing plate 711 can fit the infant's head curve closely, which not only increases the stability of the fixation, but also greatly improves the comfort of the infant during diagnosis and treatment.

[0037] Reference Figure 3 A rotating shaft frame 79 is fixedly installed on the side of the guide block 76 away from the sliding frame 71, and an arc-shaped connecting block 710 is rotatably installed in the rotating shaft frame 79. The other end of the arc-shaped connecting block 710 is fixedly connected to the fixed plate 711. This connection method can ensure that the fixed plate 711 can rotate freely and smoothly horizontally relative to the guide block 76.

[0038] Reference Figure 3 Guide grooves 77 are provided on both sides of the inner wall of the adjustment frame 73. Limit blocks 78 are slidably spliced ​​in the two sets of guide grooves 77. The limit blocks 78 are fixedly connected to the surface of the guide block 76. The limit blocks 78 cooperate with the guide grooves 77 to make the guide block 76 more stable during the movement.

[0039] Reference Figure 1 The surfaces of the two U-shaped fixing rods 4 are uniformly provided with adjustment holes 41 , and the sliding frame 71 is provided with threaded holes corresponding to the adjustment holes 41 , the threaded holes are threadedly connected with threaded nails 72 , and the threaded nails 72 are slidably plugged into the adjustment holes 41 .

[0040] Reference Figure 5 An adjusting block 43 is fixedly installed on the bottom surface of one end of the two U-shaped fixing rods 4, and a transmission mounting plate 81 is fixedly installed on the surfaces of both ends of the head support pad 1, and a bidirectional screw 82 is rotatably installed between the two sets of transmission mounting plates 81, and one end of the bidirectional screw 82 rotates to penetrate the transmission mounting plate 81 and is fixedly connected with the handle B83, and the adjusting blocks 43 at one end of the two U-shaped fixing rods 4 are respectively threadedly sleeved on both ends of the bidirectional screw 82; during specific use, the medical staff rotates the handle B83, and the handle B83 drives the bidirectional screw 82 to rotate, so that the adjusting blocks 43 sleeved on both ends of the bidirectional screw 82 move toward each other, that is, drives the two sets of U-shaped fixing rods 4 to move toward each other.

[0041] Reference Figure 6The two groups of angle adjustment components 3 include a positioning plate 31, which is fixedly mounted on the surface of the head support pad 1. A transmission rod 35 is fixedly mounted on the surface of the positioning turntable 34. The other end of the transmission rod 35 is fixedly connected to the turntable 34. A support rod 33 is rotatably mounted on the outer side of the rotating rod. A plurality of positioning holes 32 are evenly formed on the upper end surface of the positioning plate 31. The support rod 33 is provided with a through hole at the position corresponding to the positioning hole 32. An insertion rod 36 is slidably provided in the through hole. One end of the insertion rod 36 is slidably inserted into the corresponding positioning hole 32, and the other end of the insertion rod 36 is fixedly connected to the baffle 37.

[0042] A spring frame 38 is sleeved on the outside of the insertion rod 36, one end of the spring frame 38 is fixedly connected to the surface of the baffle 37, and the other end of the spring frame 38 is fixedly connected to the surface of the bracket rod 33;

[0043] During specific use, medical staff stretch the baffle 37 to both sides according to the situation of the infant or young child patient. The baffle 37 stretches the spring frame 38 and drives the insertion rod 36 to move out of the positioning hole 32. At this time, the medical staff can rotate the turntable 34, and the turntable 34 drives the head support pad 1 to rotate through the transmission rod 35 and the positioning plate 31, so as to fine-tune the angle of the head support pad 1. After the adjustment is completed, the baffle 37 is released, and the baffle is driven by the elastic force of the spring frame 38 to reinsert the insertion rod 36 into the corresponding positioning hole 32 to fix the angle of the head support pad 1.

[0044] Preferably, the surface of the head support cushion 1 is covered with a silicone pad to improve the comfort of the head support.

[0045] Preferably, a player 6 is fixedly provided at both ends of the upper surface of the head support pad 1; relaxing and joyful music is played by the player 6 to effectively distract the attention of infants and young children, and reduce the anxiety and discomfort of infants and young children in their environment.

[0046] In the present invention, when fixing the head of an infant, the first step is to place the device on the infant operating bed. The medical staff, according to the condition of the infant patient, respectively stretches the baffles 37 to both sides. The baffles 37 stretch the spring frame 38 and drive the insertion rod 36 to move out of the positioning hole 32. At this time, the medical staff can rotate the turntable 34. The turntable 34 drives the head support pad 1 to rotate through the transmission rod 35 and the positioning plate 31, so as to achieve the purpose of fine-tuning the angle of the head support pad 1. After the adjustment is completed, the baffle 37 is released. The baffle is driven by the elastic force of the spring frame 38 to reinsert the insertion rod 36 into the corresponding positioning hole 32 to achieve the angle of the head support pad 1, so that the head support pad 1 can present a small tilt angle, thereby improving the comfort of infants and young children during ophthalmic diagnosis and treatment.

[0047] In the second step, the medical staff places the infant's head in the device, and adjusts the spacing between the head fixing components 7 on the surface of the U-shaped fixing rod 4 according to the size and shape of the infant's head. After the adjustment is completed, the threaded nail 72 is rotated so that the threaded nail 72 is inserted into the corresponding adjustment hole 41 to fix the head fixing component 7; then the handle A74 is rotated to cause the guide block 76 to drive the fixing plate 711 to move up and down, so that the center position of the fixing plate 711 is aligned with the infant's head; then the handle B83 is rotated to cause the adjustment block 43 to pull the U-shaped fixing rod 4 slowly closer until the head fixing component 7 gently and firmly surrounds and fixes the infant's head. In this process, since the fixing plate 711 is rotatably connected to the rotating shaft frame 79 through the arc-shaped connecting block 710, the fixing plate 711 can rotate freely in the horizontal direction. This feature ensures that the airbag cushion 712 on the surface of the fixing plate 711 can closely fit the curve of the infant's head, which not only increases the stability of the fixation, but also greatly improves the comfort of the infant during diagnosis and treatment.

[0048] The third step is to play relaxing and joyful music through the player 6 before the diagnosis and treatment begins, so as to effectively distract the infant's attention and reduce the infant's anxiety and discomfort in his environment.

[0049] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
