Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to a cerebrospinal fluid external drainage stand, and more particularly to a cerebrospinal fluid external drainage infusion stand. Background Technology
[0002] According to records, external cerebrospinal fluid drainage refers to the placement of a drainage tube into the ventricle or spinal canal of the lumbar region to continuously drain cerebrospinal fluid. This aims to control intracranial pressure and treat intracranial infections, cerebrospinal fluid leaks, hydrocephalus, etc., and is one of the most common adjunctive treatment methods in clinical neurosurgery. In current medical practice, the height of the external cerebrospinal fluid drainage device is usually 10-15 cm from the anterior groin of the lateral ventricle, or as directed by a physician, and the height should not be arbitrarily changed. Placing the drainage device too high will result in a slow drainage rate and insufficient drainage volume, thus failing to achieve the drainage purpose; while placing it too low will result in a rapid drainage rate, leading to low intracranial pressure, inducing brain tissue displacement, new intracranial hemorrhage, or even death.
[0003] Currently, the method for determining the height of cerebrospinal fluid external drainage devices in medical practice mainly relies on visual estimation. This method suffers from problems such as unobjective zero-point horizontal positioning, inaccurate height measurement, and difficulty in quantifying height adjustment records. In addition, in hospitals, infusion stands and drainage stands are two separate devices, making the already limited bedside space even more crowded.
[0004] Based on the current state of the technology, the inventors of this application intend to provide a cerebrospinal fluid external drainage stand, particularly a cerebrospinal fluid external drainage infusion stand. The components of this drainage stand are detachable, which can meet the daily infusion needs of clinical patients and also provide a suspension position and precise height measurement for patients requiring cerebrospinal fluid external drainage. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a cerebrospinal fluid external drainage infusion stand. This infusion stand integrates an infusion stand and a cerebrospinal fluid external drainage stand, and can accurately and objectively measure the height of the drainage device, thus solving the defects and problems existing in the prior art.
[0006] To achieve the above objectives, the specific technical solution of this utility model is as follows:
[0007] A cerebrospinal fluid external drainage infusion stand includes: a main support (1) and three separable components (3)(4)(5); the main support (1) is an upright infusion stand that can be inserted next to the bed, with an infusion hook (2) at the top, and the main support is marked with graduation lines at intervals of 1 cm, which can be used for calibration with a digital rangefinder; the first component (3) consists of an adjustment knob 1 (6), an adjustment ring 1 (7), a rangefinder top plate (8), and a drainage bottle hook (9); the adjustment knob 1 and the adjustment ring 1 are used to adjust the height of the first component, and the rangefinder top plate is level with the top of the drainage tube inside the drainage bottle. The first component (4) consists of an adjustment knob 2 (10), an adjustment ring 2 (11), a rangefinder slot (12), and an infrared laser pointer fixing ring (13). The adjustment knob 2 and the adjustment ring 2 are used to adjust the height of the second component. The rangefinder slot is used to place the digital rangefinder. The infrared laser pointer fixing ring on the back of the rangefinder slot is used to fix the red laser pointer. The height of the infrared laser pointer is level with the bottom of the rangefinder slot. The second component (5) consists of an adjustment knob 3 (14), an adjustment ring 3 (15), and a drainage bag hook (16). The adjustment knob 3 and the adjustment ring 3 are used to adjust the height of the third component. The drainage bag hook is used to hang the drainage bag.
[0008] The cerebrospinal fluid external drainage infusion stand device of this utility model has been used in clinical practice, and specifically includes the following steps:
[0009] Step 1: Fix the three components to the main support and adjust them to be on the same longitudinal plane. Hang the drainage bottle of the cerebrospinal fluid external drainage device on the drainage bottle hook of the first component and hang the external ventricular drainage bag on the drainage bag hook of the third component.
[0010] Step 2: Insert the infrared laser pointer into the fixing ring on the back of the second component, turn on the infrared laser pointer, and adjust the height of the second component to make the laser pointer light source horizontally aligned with the surface of the anterior calf of the patient's lateral ventricle.
[0011] Step 3: Place the digital rangefinder upright into the rangefinder slot on the front of the second component, turn on the digital rangefinder, and adjust the height of the first component as instructed by the doctor. The rangefinder measurement result is the distance from the base of the rangefinder to the top plate of the first component. The lower edge of the top plate of the first component is at the same level as the dropper opening of the cerebrospinal fluid external drainage bottle. That is, the number displayed on the rangefinder is equal to the control height required by the doctor.
[0012] Step 4: Adjust the height of the third component so that the external ventricular drainage bag is below the bed edge to prevent cerebrospinal fluid backflow.
[0013] The results show that this invention has a simple structure, is lightweight, and saves space. It uses an infrared laser pointer for visual, objective, and accurate positioning. The electronic rangefinder provides precise distance measurement and digital display, making it easy to understand and observe. The marked scale lines can be used for calibration and also as a reference for measuring height in case of electronic equipment malfunction (e.g., power failure). Furthermore, all components and instruments are detachable for convenient equipment maintenance.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. Simple structure, lightweight body, and space-saving.
[0016] 2. Infrared laser pointer: visual, objective, and accurate positioning.
[0017] 3. Electronic rangefinder: accurate distance measurement, digital display, clear at a glance, and easy to observe.
[0018] 4. The scale lines can be used for calibration and also as a reference for measuring height when electronic equipment malfunctions (e.g., when there is no power).
[0019] 5. All components and instruments can be removed for easy equipment maintenance. Attached Figure Description
