Abstract
Description
Technical Field
[0001] The invention relates to an adjustable ventricle drainage bracket, belonging to the technical field of medical equipment. Background Art
[0002] Brain drainage surgery usually refers to brain drainage surgery, which is mainly done by placing a drainage tube in the skull through surgery, and using the drainage tube to drain the blood, bloody cerebrospinal fluid, or inflammatory cerebrospinal fluid in the skull into a drainage bag outside the body. Sometimes patients with acute obstructive hydrocephalus also need to drain excess normal cerebrospinal fluid outside the body.
[0003] At present, ventricular drainage is a commonly used treatment method for cranial surgery. Effectively controlling the drainage speed and drainage volume is a difficult point in nursing. Generally, the drainage speed and drainage volume are controlled by controlling the height of the drainage bag. Therefore, there are strict requirements for the drainage height. The opening of the drainage tube in the supine position needs to be 10 to 15 cm higher than the lateral ventricle (i.e., the ear source), and the lateral position is 15 to 18 cm higher with the midsagittal plane as the baseline. Although the above distance can be accurately located by measurement in the prior art, in some cases, such as when the patient's condition is stable, the bed board needs to be raised by 15 to 30 degrees, and the height adjustment of the drainage bag still needs to be manually operated and the drainage bag cannot be guaranteed to be raised synchronously, resulting in unstable intracranial pressure, increasing the risk of patients and the nursing workload. Summary of the invention
[0004] The purpose of the present invention is to provide an adjustable ventricular drainage bracket in order to solve the above-mentioned problem, so as to solve the problem that although the above-mentioned distance can be accurately located by measurement in the prior art, in some cases, such as when the patient's condition is stable, the bed board needs to be raised 15 to 30 degrees, the height adjustment of the drainage bag still needs manual operation and the synchronous lifting of the drainage bag cannot be guaranteed, resulting in unstable intracranial pressure, increasing the risk to the patient and the nursing workload.
[0005] The present invention is implemented through the following technical scheme: an adjustable ventricular drainage bracket, comprising a scale rack, a buckle, a hook, a sliding sleeve self-locking switch, a bracket connecting rod, a handle screw, a handle threaded shaft, a counterweight rod and a fixed base, wherein the fixed base is fixedly mounted on the bed board of the hospital bed through the handle screw, and the body of the drainage bracket and the bed board can be synchronously lifted by fixing the fixed base on the bed board, a bracket connecting rod is arranged on the fixed base, the fixed base and the bracket connecting rod are connected through the handle threaded shaft, and the bracket connecting rod rotates in the handle threaded shaft through the cooperation of the bracket connecting rod and the handle threaded shaft, a scale rack is arranged inside the bracket connecting rod, a sliding sleeve self-locking switch is installed on the scale rack, the scale rack is slidably connected to the sliding sleeve self-locking switch, a hook is fixedly mounted on the sliding sleeve self-locking switch, and rises and falls with the rise and fall of the sliding sleeve self-locking switch, a counterweight rod is arranged at the bottom of the bracket connecting rod, and counterweight is provided by setting the counterweight rod, so that the bracket connecting rod remains vertical to the ground.
[0006] As a further solution of the present invention, the fixed base and the handle screw are fixedly connected via threads.
[0007] As a further solution of the present invention, the scale of the scale rack is a grooved scale.
[0008] As a further solution of the present invention, the sliding sleeve self-locking switch includes a shell, a buckle, and a reset spring. The buckle is movably connected to the shell through the reset spring. There is a rectangular hole in the middle of the buckle. The inner side of the hole is embedded in the groove of the scale rack. The buckle is embedded and separated from the scale rack through the reset spring, thereby locking the sliding sleeve self-locking switch to slide up and down on the scale rack.
[0009] The present invention provides an adjustable ventricular drainage stent, which has the following beneficial effects:
[0010] When the patient's condition is stable, the bed board should be raised 15 to 30 degrees. Since the fixed base is fixed on the bed board, the body of the drainage bracket and the bed board can be raised synchronously. At the same time, the weight is counterbalanced by setting a counterweight rod to keep the bracket connecting rod vertical to the ground. No matter how much the patient is raised, the drainage bag can be vertical to the ground. At the same time, the position of the buckle on the scale rack can be adjusted by adjusting the self-locking switch of the sliding sleeve, thereby further adjusting the position of the drainage bag and the brain. It is simple and convenient, and there will be no pulling of the drainage bag due to changes in the position of the brain. It is very safe to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] An embodiment of the present invention provides an adjustable ventricular drainage stent.
[0016] See also Figure 1 and Figure 2 An adjustable ventricular drainage bracket comprises a scale rack 1, a buckle 2, a hook 3, a sliding sleeve self-locking switch 4, a bracket connecting rod 5, a handle screw 6, a handle threaded shaft 7, a counterweight rod 8 and a fixed base 9. The fixed base 9 is fixedly mounted on the bed board of the hospital bed through the handle screw 6. The fixed base 9 and the handle screw 6 are fixedly connected by threads. By fixing the fixed base 9 on the bed board, the body of the drainage bracket and the bed board can be synchronously raised. A bracket connecting rod 5 is provided on the fixed base 9. The fixed base 9 is connected to the bracket connecting rod 5 through the handle threaded shaft 7. The bracket connecting rod 5 rotates in the handle threaded shaft 7 through the cooperation of the bracket connecting rod 5 and the handle threaded shaft 7. A scale is provided inside the bracket connecting rod 5. Rack 1, the scale of the scale rack 1 is a groove-type scale, a sliding sleeve self-locking switch 4 is installed on the scale rack 1, the scale rack 1 is slidably connected to the sliding sleeve self-locking switch 4, the sliding sleeve self-locking switch 4 includes a shell, a buckle 2, and a reset spring 12. The buckle 2 is movably connected to the shell through the reset spring 12. There is a rectangular hole in the middle of the buckle 2, and the inner side of the hole is embedded in the groove of the scale rack 1. The buckle 2 is embedded and separated from the scale rack 1 through the reset spring 12, so as to lock the sliding sleeve self-locking switch 4 to slide up and down on the scale rack 1. A hook 3 is fixedly installed on the sliding sleeve self-locking switch 4, which rises and falls with the rise and fall of the sliding sleeve self-locking switch 4. A counterweight rod 8 is arranged at the bottom of the bracket connecting rod 5, and the counterweight rod 8 is arranged to counterweight, so that the bracket connecting rod 5 remains vertical to the ground.
[0017] Working principle: When the patient's condition is stable, the bed board should be raised 15 to 30 degrees. Since the fixed base 9 is fixed on the bed board, the body of the drainage bracket and the bed board can be raised synchronously. At the same time, the counterweight rod 8 is set for counterweighting, so that the bracket connecting rod 5 remains vertical to the ground. No matter how much the patient is raised, the drainage bag can be vertical to the ground. At the same time, the position of the buckle 2 on the scale rack 1 can be adjusted by adjusting the sliding sleeve self-locking switch 4, so as to further adjust the position of the drainage bag and the brain. It is simple and convenient, and there will be no pulling of the drainage bag due to changes in the position of the brain. It is very safe to use.
