Description

A head drainage tube fixing device

technical field

The utility model belongs to the field of medical instruments, in particular to a head drainage tube fixing device.

Background technique

After the operation is performed clinically, it is generally necessary to indwell a drainage tube. During the indwelling period of the drainage tube, whether the drainage tube is fixed firmly and whether the drainage is unobstructed is the key to the success of the operation and the recovery of the patient. Due to the displacement of the catheter, the catheter needs to be repositioned, which will lead to delays in the treatment effect and time, and even endanger the patient's life due to infection. In order to achieve the purpose of fixing the drainage tube, the traditional method is to fix the drainage tube on the patient's skin with silk suture. This method has many shortcomings: silk suture aggravates tissue trauma and is more likely to cause infection; the patient is involved in daily activities after surgery. The suture will cause pain; the drainage tube is easily bent during daily activities, which may lead to dangerous situations; if the silk thread loosens or falls off, it will be sutured again to fix the drainage tube.

In the prior art, a self-made static point stand marked with a scale is mostly used for the hanging drainage bag. After manual measurement, the doctor uses a string tape to tie it to the bedside or an object adjacent to the bedside, and pulls the string when moving the patient. This has certain shortcomings: if it affects the hanging height, it is easy to touch when it is tied to the bedside. Strings, creating hazards such as detachment of the tube, and the need to remeasure the height after moving the patient. Since there is a certain distance between the head of the patient and the head of the bed, there will also be a large error in the measurement, which is not conducive to postoperative drainage of the patient, and its use accuracy is poor and extremely inconvenient to use. At the same time, after the height of the hook for suspending the drainage bag is determined, it needs to be fixed by adjusting the nut, which is cumbersome to operate.

In addition, the existing drainage fixing device, such as the cerebral ventricular drainage fixing device disclosed in CN205460373U, can only fix the drainage tube, but cannot fix the drainage bag. If the drainage bag is bumped or shaken, it will still shake. During the actual drainage process, the drainage tube fixed outside the ventricle will accidentally fall off, which will lead to a variety of accidents. If the random repositioning is too high, it will cause high intracranial pressure and lead to insufficient drainage; if it is too low, it will cause Causes excessive drainage, causing the patient to have a headache. If the accidental shedding is not detected in time, it may even lead to intracranial hemorrhage, directly endangering the life of the patient.
