A head fixation device for medical care of children

Abstract

The present invention discloses a head fixing device for medical care of children, and relates to the field of medical care technology. It comprises a protective device, wherein two fixing blocks are fixedly arranged on the inner wall of the protective device, an adjusting rod is fixedly arranged between the two fixing blocks, and an adjusting groove is penetrated through the outer wall of the protective device. By pulling the shifting block, the limiting block is driven to separate from the outer wall of the protective device, and the adjusting block is driven to move in the adjusting groove by pulling the first control block, thereby changing the width between the two adjusting devices. The clamping plates arranged at the two adjusting devices clamp and fix the child's head, and the shifting block is released. The limiting block is reset to fit with the outer wall of the protective device under the elastic action of the elastic spring, thereby ensuring the stability of the two adjusting devices. The two clamping plates are arranged to leave a small angle of rotation space with the child's head, which effectively avoids the problem that when the clamping device clamps the child's head, the child's head is easily damaged due to the clamping device being fixed too tightly.

The connecting plate 512 is fixedly connected with a clamping plate 509. When the child's head is fixedly clamped inside the two adjusting devices 5, the two clamping plates 509 are arranged to leave a small angle of rotation space between the child's head, which effectively avoids the problem that the clamping device is too rigid when clamping the child's head, which may cause damage to the child's head. After the adjustment is completed, the binding layer 2 is tied by the strap buckle 301. The belt is fixed on the child's head to ensure that the head remains stable during the treatment process. At the same time, a fixed base 6 is arranged at the bottom of the protective device 1. A bidirectional screw rod 7 is rotatably inserted into the outer wall of the fixed base 6. Two opposing sliding blocks 9 are threadedly arranged on the outer wall of the bidirectional screw rod 7. A fixed plate 10 is arranged on the top of the sliding block 9. An inflator 13 is arranged on one side of the fixed plate 10, and a protective airbag 11 is arranged on the other side. The second control block 8 is turned to drive the bidirectional screw rod 7 to rotate. As the bidirectional screw rod 7 rotates, the internal space of the protective device 1 can be adjusted to adapt to the head size and shape of different children. The inflator 13 inflates the protective airbag 11 through the inflation tube 14. 1 is inflated to expand the air cushion, thereby providing additional support and protection, ensuring the comfort and safety of the child's head during treatment. Through the precise adjustment of the bidirectional screw rod 7, all-round protection of the child's head can be achieved, while avoiding discomfort or injury that may be caused by over-tightening. In addition, the design of the protective device 1 takes into account the physiological characteristics of children and the actual needs of medical care, making the device convenient and safe during use, greatly improving the efficiency and quality of children's medical care. The protective airbag 11 can be connected to the inflator 13 through the inflation tube 14, and the air cushion can be inflated or deflated as needed to provide additional support and comfort.
