[0002] Ventricular drainage tube is the most common drainage tube after cranial surgery in neurosurgery. It can quickly reduce intracranial pressure, drain intracranial blood, reduce cerebrospinal fluid leakage from the wound, and promote wound healing. In order to control the drainage rate of cerebrospinal fluid, the height of the drainage bag needs to be 10-15cm higher than the level of the lateral ventricle when the patient is in the supine position, that is, 10-15cm above the level of the external auditory canal, and 15-18cm higher than the midsagittal plane when the patient is in the lateral position. The drainage tube is usually installed on the side of the patient's bedside through a fixed structure.

[0003] Currently, when a patient is using a drainage tube, if the patient needs to go out for examination or moves, medical staff are required to readjust the drainage tube again. The more commonly used measurement method requires the use of a level measuring instrument, which is cumbersome to operate, and the position height of the drainage tube cannot be accurately adjusted.

[0004] Therefore, we propose a ventricular drainage tube adjustment device to solve the above problems. Utility Model Content

[0027] The drainage mechanism 32 includes a drainage tube 321 and a marking block 322 fixedly mounted on one side of the upper end of the outer wall of the drainage tube 321 . An embedding block 323 is fixedly mounted in the middle of one end of the outer wall of the marking block 322 .

[0028] A circular screw groove 324 is provided in the middle of the upper end of one side of the embedded block 323, and a short screw rod 325 is threadedly connected to the inner cavity of the circular screw groove 324, and a pressure plate 326 is fixedly installed on one end of the outer wall of the short screw rod 325.

[0029] The short screw 325 drives the pressure plate 326 to be threadedly pressed against one end of the notch of the groove 312 , thereby fixing the position of the embedded block 323 .

[0030] In this embodiment: after aligning the zero point, the operator moves the drainage tube 321 to move the marking block 322 according to the calculated adjustment height, so that the embedded block 323 fixedly installed at one end of the marking block 322 slides in the inner cavity of the groove 312, and then moves the marking block 322 to the specified position according to the marking line 313, and then the short screw 325 and the circular screw groove 324 are threadedly connected, so that the short screw 325 drives the pressure plate 326 to be pressed and fixed on one end of the notch of the groove 312, thereby completing the fixation of the position of the embedded block 323 and completing the adjustment of the height of the drainage tube 321 at the same time, and performing precise adjustment according to the marking line 313, and it is convenient to use.

[0031] Embodiment 2: This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 2-Figure 3 The installation component 2 includes a wrapping mechanism 21 and an infrared measuring instrument 22 fixedly installed at one end of the outer wall of the wrapping mechanism 21. The wrapping mechanism 21 is installed and arranged in a position suitable for driving the infrared measuring instrument 22 and the adjustment component 3.

[0032] The wrapping mechanism 21 includes a hollow opening block 211 and a threaded groove 212 opened in the middle of one side of the inner wall of the hollow opening block 211. A threaded rod 213 is threadedly connected in the inner cavity of the threaded groove 212. A bearing 214 is fixedly installed at one end of the threaded rod 213. A semicircular clamping block 215 is fixedly installed at one end of the bearing 214. The threaded rod 213 and the threaded groove 212 are threadedly connected to drive the semicircular clamping block 215 to be telescopically installed in the inner cavity of the hollow opening block 211.

[0033] In this embodiment: because the fixing rod 1 is movably installed in the inner cavity of the hollow opening block 211, and the threaded rod 213 and the threaded groove 212 are threadedly connected, the threaded rod 213 is rotated clockwise to drive the bearing 214 and the semicircular clamping block 215 to advance toward one end of the outer wall of the fixing rod 1, so that the semicircular clamping block 215 is fitted and fixed to one end of the outer wall of the fixing rod 1, and the semicircular clamping block 215 and the inner wall side of the hollow opening block 211 clamp and fix the fixing rod 1. Similarly, the threaded rod 213 is rotated counterclockwise to drive the bearing 214 and the semicircular clamping block 215 away from one end of the outer wall of the fixing rod 1, loosening the fixation of the fixing rod 1, and through the movable adjustment of the hollow opening block 211, the hollow opening block 211 drives the adjustment component 3 and the infrared measuring instrument 22 to adjust the setting position, so as to facilitate the operator to use the infrared measuring instrument 22 to perform zero point alignment operation.

[0034] Working principle: By rotating the threaded rod 213 clockwise, the bearing 214 and the semicircular clamp block 215 are pushed toward one end of the outer wall of the fixed rod 1, so that the semicircular clamp block 215 is fixed to one end of the outer wall of the fixed rod 1. By adjusting the position of the hollow opening block 211, the hollow opening block 211 drives the adjustment component 3 and the infrared measuring instrument 22 to adjust the setting position, so that the operator can use the infrared measuring instrument 22 to perform zero point alignment operation. After aligning the zero point, the operator adjusts the height according to the calculation. The movable drainage tube 321 drives the marking block 322 to move together, so that the embedded block 323 fixedly installed at one end of the marking block 322 slides in the inner cavity of the groove 312, and then the marking block 322 is moved to the specified position according to the marking line 313, and then the short screw 325 and the circular screw groove 324 are threadedly connected by rotating the short screw 325, so that the short screw 325 drives the pressure plate 326 to be pressed and fixed on one end of the notch of the groove 312, thereby completing the fixation of the position of the embedded block 323 and completing the adjustment of the height of the drainage tube 321 at the same time.
