In addition, start the second telescopic rod to drive the inner hollow frame to flip around the second transmission rod at the top of the Y-shaped support rod, thereby adjusting the angle between the size adjustment structure and the main support frame, simulating the patient's head raising and lowering action, so that the patient can do a simple head and neck muscle stretching action without damaging the wound surface and stretching the infusion tube.

[0028] S3, the third hinge point installed at both ends of the first telescopic rod is hinged with the first hinge point to prevent the first telescopic rod from getting stuck when pushing the inner hollow frame, the fourth hinge point installed at both ends of the second telescopic rod is also hinged with the second hinge point to prevent the second telescopic rod from getting stuck when pushing the inner hollow frame, and the second transmission rod is hinged with the Y-shaped support rod, and the first transmission rod is hinged with the inner hollow frame, so that the angle of the patient's head can be flexibly adjusted from four directions, reducing the sense of restraint caused by the patient being fixed.

[0029] S4. By installing the main support frame on the backrest of the double-sided seat, and providing two groups of movable structures, the device can serve more child patients. The function of the movable structure is to drive the angle adjustment structure and the size adjustment structure on one side to move through the magnetic limit track and the magnetic limit slider after power is turned on, so as to facilitate moving the device to the patient's position. The lifting track can also drive the angle adjustment structure to move up and down, so as to adjust the height of the device according to the length of the patient's upper body and improve the comfort of the device.

[0030] The present invention provides a fixation device and a fixation method for pediatric auxiliary infusion through improvement, which has the following improvements and advantages compared with the prior art:

[0031] Firstly, the head support frame adopts an open design, which is more inclusive than the traditional ring-shaped headgear design. In addition, the size of the head circumference adjuster can be adjusted adaptively according to the patient's head size and shape, reducing the restriction and pressure of the device on the head size of children, and there are fewer restrictions on the use of children with larger heads and older children.

[0032] Specifically, the hollow slider is driven to move by starting the telescopic motor, and when the hollow slider moves, the internal transmission gear is driven to move along the direction of the fixed rack. When the transmission gear moves, the teeth on the fixed rack drive the transmission gear to rotate, thereby driving the head circumference adjuster at the bottom to rotate. The embedded grooves on the head circumference adjuster are of different sizes and can be adjusted according to the size of the patient's head to better fit the patient's head shape and improve the comfort of child patients. In addition, the protective net on one side of the fixed rack is used to protect the patient's head during infusion, and to avoid secondary damage to the patient's infusion wound when the child patient encounters an accident or collision during the infusion process;

[0033] Secondly, the angle adjustment structure can protect the patient's head and shoulder and neck muscles, relieve muscle tension caused by infusion, avoid muscle soreness caused by the patient's head keeping a posture for a long time and local blood circulation problems caused by compression and tension.

[0034] Specifically, the first telescopic rod is extended and retracted to push the inner hollow frame to flip around the first transmission rod, thereby adjusting the angle between the size adjustment structure and the main support frame, simulating the patient's head turning action, so that the patient can do a simple head, shoulder and neck muscle stretching action without damaging the wound surface and stretching the infusion tube. In addition, the second telescopic rod is started to drive the inner hollow frame to flip around the second transmission rod at the top of the Y-shaped support rod, thereby adjusting the angle between the size adjustment structure and the main support frame, simulating the patient's head raising and lowering action, so that the patient can do a simple head and neck muscle stretching action without damaging the wound surface and stretching the infusion tube.

[0035] Thirdly, the third hinge point installed at both ends of the first telescopic rod can be hinged to the first hinge point, so as to avoid the first telescopic rod from getting stuck when pushing the inner hollow frame. The fourth hinge point installed at both ends of the second telescopic rod is also hinged to the second hinge point, so as to avoid the second telescopic rod from getting stuck when pushing the inner hollow frame. In addition, the second transmission rod is hinged to the Y-shaped support rod, and the first transmission rod is hinged to the inner hollow frame, so as to flexibly adjust the angle of the patient's head from four directions and reduce the sense of restraint caused by the patient being fixed.

[0036] In addition, the main support frame is installed on the backrest of the double-sided seat, and two groups of mobile structures are provided so that the device can serve more child patients. The function of the mobile structure is to drive the angle adjustment structure and size adjustment structure on one side to move through the magnetic limit track and the magnetic limit slider after power is turned on, so as to facilitate moving the device to the patient's position. The lifting track can also drive the angle adjustment structure to move up and down, so as to adjust the height of the device according to the length of the patient's upper body and improve the comfort of the device.

[0075] Specifically, the hollow slider 403 is driven to move by starting the telescopic motor 402. When the hollow slider 403 moves, it drives the internal transmission gear 408 to move along the direction of the fixed rack 406. When the transmission gear 408 moves, the teeth on the fixed rack 406 will drive the transmission gear 408 to rotate, thereby driving the head circumference adjuster 405 at the bottom to rotate. The embedded grooves on the head circumference adjuster 405 are of different sizes and can be adjusted according to the size of the patient's head to better fit the patient's head shape and improve the comfort of child patients.

[0076] Then, the angle adjustment structure 3 can protect the patient's head and shoulder and neck muscles, relieve the muscle tension caused by infusion, avoid muscle soreness caused by the patient's head keeping a posture for a long time and local blood circulation problems caused by compression and tension.

[0077] Specifically, the first telescopic rod 302 is telescopically extended to push the inner hollow frame 305 to flip around the first transmission rod 306, thereby adjusting the angle between the size adjustment structure 4 and the main support frame 2, simulating the patient's head turning action, so that the patient can do a simple head, shoulder and neck muscle stretching action without damaging the wound surface and without stretching the infusion tube. In addition, the second telescopic rod 303 is activated to drive the inner hollow frame 305 to flip around the second transmission rod 312 at the top of the Y-shaped support rod 304, thereby adjusting the angle between the size adjustment structure 4 and the main support frame 2, simulating the patient's head raising and lowering action, so that the patient can do a simple head and neck muscle stretching action without damaging the wound surface and without stretching the infusion tube.

[0078] In addition, the third hinge point 310 installed at both ends of the first telescopic rod 302 is hinged to the first hinge point 308, thereby preventing the first telescopic rod 302 from getting stuck when pushing the inner hollow frame 305. The fourth hinge point 311 and the second hinge point 309 installed at both ends of the second telescopic rod 303 are also hinged, and at the same time, preventing the second telescopic rod 303 from getting stuck when pushing the inner hollow frame 305. In addition, the second transmission rod 312 and the Y-shaped support rod 304 are hinged, and the first transmission rod 306 and the inner hollow frame 305 are hinged, which is convenient for flexibly adjusting the angle of the patient's head from four directions and reducing the sense of restraint caused by the patient being fixed.

[0079] Finally, by installing the main support frame 2 on the backrest of the double-sided seat, and providing two groups of movable structures 1, the device can serve more child patients. The function of the movable structure 1 is to drive the angle adjustment structure 3 and the size adjustment structure 4 on one side to move through the magnetic limit track 101 and the magnetic limit slider 102 after power is turned on, so as to facilitate moving the device to the patient's position.
