DETAILED DESCRIPTION

[0027] The utility model will be further described below in conjunction with the accompanying drawings.

[0028] like Figures 1 to 3 as well as Figure 7 and Figure 8As shown, a preferred embodiment of the support device for post-cranial and cerebral surgery dressing change of the utility model comprises a fixed plate 1, a movable plate 2, a fixed frame 3, a fixed belt 22, a limiting mechanism 5, a traction mechanism 6 and a lamp holder 71. The movable plate 2 is provided with a dressing hole 20, and the movable plate 2 is provided with a buffer pad for buffering to reduce the pressure on the patient. The movable plate 2 is hinged to the fixed plate 1 by a resistance hinge, so that the movable plate 2 can rotate slowly, especially when the movable plate 2 is lowered, it will not cause impact to the head. The fixed frame 3 is installed on the fixed plate 1, and there are two fixed frames 3, and each fixed frame 3 is provided with a pulley 31. Two traction ropes 4 are fixed on the movable plate 2, and the two traction ropes 4 are respectively located on both sides of the movable plate 2. The traction mechanism 6 is installed on the fixed plate 1. Two reels 8 are installed on the output shaft 62 of the traction mechanism 6, and one reel 8 corresponds to one pulley 31. The other end of the traction rope 4 passes around the pulley 31 and is fixed to the reel 8 of the traction mechanism 6. The traction mechanism 6 is used to drive the output shaft 62 to rotate and drive the reel 8 to reel in the traction rope 4. The limiting mechanism 5 is connected to the traction mechanism 6, and the limiting mechanism 5 is used to limit the unidirectional rotation of the output shaft 62. When the limiting mechanism 5 limits the output shaft 62, the output shaft 62 can only rotate in the direction of the reel 8 reeling in the traction rope 4. The fixing belt 22 is used to fix the patient. The fixing belt 22 passes around the armpit to fix the patient to prevent the patient's head from falling under the movable plate 2. The lamp holder 71 is mounted on the movable plate 2 through a resistance shaft, so that the lamp holder 71 can be suspended at any position. A lighting lamp 72 is mounted on the lamp holder 71, and the lighting lamp 72 is used for supplementary lighting. When supplementary lighting is not needed, the lamp holder 71 is folded and flush with the movable plate 2 to reduce the occupied space. When dressing needs to be changed, the traction mechanism 6 drives the reel 8 to rotate, and the reel 8 reels the traction rope 4 to pull the movable plate 2 to flip, so that the movable plate 2 flips upward, thereby lifting the patient's head, and the medical staff can change the dressing through the dressing hole 20. If the light is insufficient, the lighting lamp 72 can be turned on to supplement the light. Of course, in other embodiments, the traction rope 4, the pulley 31 and the reel 8 can also be fixed only on one side of the movable plate 2.

[0029] like Figure 4 and Figure 5 As shown, the traction mechanism 6 includes a handle 61 and an output shaft 62, the output shaft 62 is rotatably arranged on the fixing frame 3, the handle 61 is fixed to the output shaft 62 by a screw 63, and the reel 8 is fixed to the output shaft 62. In other embodiments, the traction mechanism 6 can also be replaced by a combination of a motor and a reducer, the reducer is connected to the motor, the motor drives the reducer, and the reducer drives the output shaft 62 to rotate, and the electrode and the reducer can also be installed on the bed frame of the bed.

[0030] like Figure 6 and Figure 7 As shown, the limiting mechanism 5 includes a ratchet 51, a pawl 52, a lever 53 and a reset spring 54. The ratchet 51 is fixed on the output shaft 62, the pawl 52 is rotatably arranged on the fixing frame 3, the lever 53 is fixed on the pawl 52, and the reset spring 54 is used to reset the pawl 52. The pawl 52 is stuck on the ratchet 51 without the action of external force, so that the ratchet 51 can only rotate in a limited direction. When the lever 53 moves upward, it drives the pawl 52 to rotate up and down, thereby contacting the restriction of the ratchet 51, and the ratchet 51 can rotate in any direction at this time.

[0031] The fixing frame 3 is provided with a receiving groove 32, and the receiving groove 32 is used to receive the limiting mechanism 5. The receiving groove 32 is provided with a cover plate 33, and the cover plate 33 is used to seal the receiving groove 32. The pawl 52, the ratchet wheel 51 and the return spring 54 are all located in the receiving groove 32, and the lever 53 passes through the cover plate 33 and is exposed outside the cover plate 33. The cover plate 33 is provided with an arc hole 331, and the lever 53 is located in the arc hole 331, so that the lever 53 can move to drive the pawl 52 to rotate, thereby releasing the restriction of the pawl 52 on the ratchet wheel 51.

[0032] The fixing belt 22 includes a first belt body and a second belt body, wherein the first belt body is fixed to the front end of the movable plate 2, and the second belt body is fixed to the rear end of the movable plate 2, and the first belt body and the second belt body are connected by Velcro, and in other embodiments, they can also be connected by buckles. The fixing belt 22 is provided in two parts, which can facilitate the fixation of the patient.

[0033] like Figure 8 and Fig. 9 As shown, when dressing change is needed, the handle 61 is turned to drive the output shaft 62 to rotate, and the output shaft 62 rotates to drive the reel 8 to rotate, and the reel 8 rotates to reel in the traction rope 4, thereby driving the movable plate 2 to flip upward, and finally exposing the dressing hole 20, and the dressing change operation can be performed by releasing the handle 61. After the dressing change is completed, when the patient needs to be put down, the lever 53 is pulled upward to release the restriction of the ratchet 52 on the ratchet 51, and the patient slowly presses down the movable plate 2 under gravity. The dressing change can be performed by one person, and the head movable plate 2 supports the head, so that the back of the head is suspended in the air without pressure, so that the head is breathable, which is conducive to wound recovery and reduces the possibility of pressure sores.

[0034] The above are only implementation methods of the present utility model, and are not intended to limit the patent scope of the present utility model. Any equivalent structure made using the contents of the specification and drawings of the present utility model, directly or indirectly used in other related technical fields, are also within the patent protection scope of the present utility model.
