Abstract
Description
Technical Field
[0001] This utility model relates to the field of drainage support technology, and specifically to a drainage auxiliary device. Background Technology
[0002] Traumatic brain injury, chest injury (pleural effusion, pneumoplegia), and acute heart failure are very common diseases among critically ill patients in clinical practice. Postoperative drainage and central venous pressure measurement are frequently used in clinical practice after traumatic brain injury and chest injury surgery. The surgical outcome is affected by many factors, and the postoperative drainage situation can directly affect the surgical outcome. Accurate measurement of central venous pressure can accurately reflect the status of blood volume and cardiac function.
[0003] Postoperatively, patients undergoing craniocerebral surgery require the placement of drainage devices (drainage devices: drainage bottles connected to drainage bags). However, the required fixation height varies depending on the drainage location. For example, in patients undergoing external ventricular drainage, the drainage bottle should be fixed 10-15 cm above the level of the lateral ventricle to better maintain stable intracranial pressure; in patients undergoing subdural hematoma surgery, the drainage bag should be fixed 30 cm below the wound surface; and in patients undergoing lumbar cistern drainage, the height needs to be adjusted according to the drainage volume. For closed thoracic drainage, because the thoracic cavity is under negative pressure, to prevent retrograde infection due to backflow of drainage fluid, the plane of the patient's closed thoracic drainage bottle must be at least 60 cm below the plane of the thoracic drainage opening.
[0004] Currently, the traditional method of fixing the drainage tube requires medical staff to use a ruler to measure, which increases the workload and may result in measurement errors. Some surgeons also determine the fixing position of the drainage bottle based on their own clinical experience, which reduces the accuracy of drainage. Utility Model Content

[0034] Example 2
[0035] like Figures 1-7 As shown, based on the above embodiments, this embodiment further provides the following:
[0036] The lower hook assembly 6 includes a U-shaped step plate 61. The U-shaped step plate 61 is slidably connected within the height adjustment groove 5. A locking threaded rod 62 is threadedly connected to the U-shaped step plate 61. One end of the locking threaded rod 62 is rotatably connected to an abutment plate 63. The abutment plate 63 slides within the U-shaped step plate 61. A hook component 64 is connected to the lower part of the U-shaped step plate 61.

[0038] Example 3
[0039] like Figures 1-7 As shown, based on the above embodiments, this embodiment further provides the following:
[0040] A vertical groove 12 is provided on the upper part of one side of the scale 4. A locking bolt 13 is internally threaded onto the vertical rod 1. One end of the locking bolt 13 is connected to a locking plate 14, which slides within the vertical groove 12.

[0041] By cooperating with the locking bolt 13 and the locking plate 14, the height of the scale 4 can be adjusted. At this time, the height adjustment groove 5 on the side of the scale 4 can be used to measure the drainage bottle and physiological saline.
[0042] Working principle and usage process of this utility model:
[0043] In use:
[0044] First, the movable gripper 23 is moved. As the movable gripper 23 moves, it compresses the reset damping rod 24. With the movement of the movable gripper 23 and the reset damping rod 24, the entire device can be fixed to the side of the bed. After fixing, the height of the drainage bottle can be precisely adjusted according to various types of drainage, such as post-craniotomy drainage and closed thoracic drainage. Since the scale of the ruler is -60cm to 50cm and the infrared pen 8 is located at the 0 mark, and since two sets of first hooks 644 are installed at the bottom of the ruler, the drainage bag can be suspended through the two sets of first hooks 644. The first hooks can be adjusted to be lower than the drainage plane as needed (20cm, 30cm, 40cm, 50cm and 60cm lower than the drainage plane) to ensure drainage accuracy. Secondly, it can measure central venous pressure. The infrared measuring pen 8 at the 0-point pressure measuring tube on the upper part of the adjustment frame is level with the middle of the right atrium. The upper scale (0 to 50cm) has an infusion groove 7, and the lower scale (0 to -15cm) has an infusion groove, which can measure negative values. Thirdly, there are three hooks at the top of the scale. The storage hook 11 is aligned with the infusion groove 7 to hang the central venous pressure measuring infusion bag of normal saline; there is a hanging hook 10 on each side for hanging drainage bottles. Fourthly, there is an identification box at the top of the scale for hanging drainage bottles. The identification box includes information on left ventricular drainage, right ventricular drainage, subdural drainage, hematoma cavity drainage, lumbar cistern drainage, closed thoracic drainage, and central venous pressure measurement. The identification can be rotated to select the appropriate type of drainage, so that staff can better understand the patient's drainage type and prevent potential safety hazards.
[0045] The outer layer of the label box is a transparent protective cover, and the inner hexagonal surface has a label for medical staff to view.
