DETAILED DESCRIPTION

[0022] The utility model is further described below in conjunction with the accompanying drawings:

[0023] When patients undergo extraventricular drainage, they need to keep the drainage bag on the drainage tube 10-15 cm higher than the location of the drainage tube punctured on the patient's head, thereby avoiding excessive or insufficient drainage of cerebrospinal fluid, which may affect the treatment effect of the disease or cause low intracranial pressure.

[0024] In actual use, the patient's head can be adjusted in height through the movable bed head, so that the drainage bag on the corresponding external ventricular drainage tube can also be further adjusted in height. In order to reduce the burden on the staff, the fixed adjustment of the drainage bag is more accurate and stable. Figure 1 and2 A novel external ventricular drainage fixing device shown in the figure comprises a fixing seat 1 installed on the side of a movable bed head, a mounting seat 2 slidably connected to the fixing seat 1, a telescopic rod 3 rotatably connected to the mounting seat 2, and a hook 4 installed on the telescopic rod 3 and adjusted in height through the telescopic rod 3, a vertical positioning seat 5 installed on the ground is provided at the lower end of the telescopic rod 3, and the telescopic rod 3 is slidably installed on the vertical positioning seat 5; Figure 1 As shown, the device is installed on the side of the movable bedside through the fixing seat 1, so that the line connecting the fixing seat 2 and the puncture position of the patient's head is parallel to the rotation center line of the movable bedside; the telescopic rod 3 is ensured to be in a vertical state when the height of the movable bedside is adjusted through the vertical positioning seat 5; specifically, when in use, the movable bedside is rotated and lifted upward around the rotation center, so that the fixing seat 1 drives the mounting seat 2 and the telescopic rod 3 to move upward, and during the movement, the telescopic rod 3 moves upward relative to the vertical positioning seat 5 while the mounting seat 2 moves forward relative to the fixing seat 1 until the adjustment of the position of the movable bedside stops, so that the height change of the telescopic rod 3 is the same as the height change of the puncture position of the patient's head, so that the height difference between the drainage bag height after the adjustment of the movable bedside position and the position of the patient's puncture drainage tube is consistent with that before the adjustment, and then after the adjustment of the movable bedside is completed, there is no need to re-adjust the height of the drainage bag of the extracerebral ventricular drainage tube;

[0025] Further, such as Figure 1 As shown, in order to install and adjust the position of the fixing device in this embodiment, the fixing seat 1 can be detachably installed on the side of the movable bed head, and the vertical positioning seat 5 can be detachably installed on the ground; specifically, as Figure 5 As shown, the fixed seat 1 in this embodiment includes a seat body 1-1, a clamping groove 1-2 opened in the seat body 1-1, a clamping plate 1-3 located in the clamping groove 1-2, a threaded rod 1-4 fixedly connected above the clamping plate 1-3 and threadedly connected to the seat body 1-1, and a handle 1-5 installed on the outside of the threaded rod 1-4 for driving the threaded rod 1-4 to rotate; when in use, the movable bed head is clamped in the clamping groove 1-2, and the threaded rod 1-4 is rotated by the handle 1-5 so that the threaded rod 1-4 drives the clamping plate 1-3 to move to one side of the movable bed head and clamp and fix the movable bed head;

The lower end of the telescopic rod 3 is provided with a sliding channel 6 sleeved on the outside of the positioning rod 5-2. The positioning rod 5-2 is vertically fixed by the positioning portion 5-1, so that the telescopic rod 3 sleeved on the outside of the positioning rod 5-2 can only move in the up and down directions, thereby avoiding the position deviation of the telescopic rod 3 when the height is adjusted, ensuring that the telescopic rod 3 is in a vertically set position state;

[0027] Specifically, Figure 1 and 5 As shown, the mounting seat 2 in this embodiment includes a sliding hole 2-1 opened on the fixed seat 1, a mounting rod 2-2 slidably connected in the sliding hole 2-1, and a rotating connecting seat 2-3 fixedly connected to the mounting rod 2-2, and a mounting cavity 7 rotatably connected to the telescopic rod 3 through a rotating shaft is opened on the inner side of the rotating connecting seat 2-3; the rotating connecting seat 2-3 in this embodiment is fixedly connected to the front end of the mounting rod 2-2, and the mounting rod 2-2 can move back and forth in the sliding hole 2-1, so that when the movable bed head is lifted, the mounting rod 2-2 and the rotating connecting seat 2-3 are lifted together with the fixed seat 1, and since the telescopic rod 3 can only move up and down in the vertical direction along the positioning rod 5-2, the rotating connecting seat 2-3 is rotatably connected to the telescopic rod 3 and the rotating connecting seat 2-3 can move back and forth relative to the fixed seat 1, so that the telescopic rod 3 can be lifted as the movable bed head is lifted while ensuring that the telescopic rod 3 is in a vertical state;

[0028] Furthermore, the telescopic rod 3 in this embodiment includes a fixed rod 3-1 connected to the mounting seat 2 and an adjusting rod 3-2 slidably connected to the upper end of the fixed rod 3-1; specifically, as Figure 2 and 4 As shown, an adjustment hole 3-3 is provided on the inner side of the fixing rod 3-1, and the adjusting rod 3-2 is slidably connected in the adjusting hole 3-3, and a locking piece 8 connected to the adjusting hole 3-3 is threadedly connected on the fixing rod 3-1; further, in order to make the height adjustment more accurate, a numerical scale for displaying the height is provided on the outer side of the adjusting rod 3-2 in this embodiment; wherein, the locking piece 8 can be a locking nut, and when in use, the locking piece 8 is unscrewed and then the height of the adjusting rod 3-2 is adjusted up and down, and after the adjusting rod 3-2 is adjusted up and down to the required height, the locking piece 8 is screwed back, so that the locking piece 8 is pressed against the outer surface of the adjusting rod 3-2 to lock and fix the adjusting rod 3-2.
