Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a drainage warning device. Background Art

[0002] Intracranial drainage is based on the siphon principle. By controlling the size and height of the two ports of the drainage tube, the intracranial fluid can be drained into the drainage bag. The drainage speed and drainage volume can be adjusted by controlling the height of the drainage outlet, that is, the height of the drainage bag. In the intracranial drainage surgery, after the successful placement of the catheter, the most important thing for continuous external drainage of cerebrospinal fluid is how to control the drainage speed of cerebrospinal fluid. Too fast a speed will lead to excessive drainage and cause acute brain herniation, which is life-threatening. Too slow a speed will lead to poor drainage. Ultimately, due to the small inner diameter of the drainage tube itself, it is very easy to cause tube blockage, and finally form or further aggravate the occurrence of intracranial infection. In actual clinical practice, the drainage speed and drainage volume are usually mastered by the doctor based on personal experience and cannot be directly judged.

[0003] Another thing is that in ventricular drainage, the amount of cerebrospinal fluid formed in the human brain every day is basically constant, about 500 ml / d. This cerebrospinal fluid is mainly released slowly by the choroid of the ventricles. During the drainage process, maintaining a continuous and balanced drainage speed is the most critical. The key to determining the drainage speed lies in the relative height of the drainage device suspended above the level of the external auditory canal. Generally, the hanging height is required to be 10 to 15 cm above the level of the external auditory canal. In the past, this height was mainly measured visually, which was not accurate enough.

[0004] Chinese patent application CN208405174U discloses a cerebrospinal fluid external drainage fixing device. In order to accurately adjust the cerebrospinal fluid external drainage speed, a cylindrical metal rod is designed to be fixed on the head of the bed and kept perpendicular to the ground. The T-shaped sleeve is fixed on the cylindrical metal rod by a fixing clamp. The T-shaped sleeve longitudinally fixes the drainage pump, the drainage pump is marked with a ruler and can be adjusted up and down in height. The T-shaped sleeve transversely fixes a laser pen for accurately measuring the height of the patient's external auditory canal. In this way, the height of the drainage pump can be adjusted at any time when adjusting the patient's head position to prevent excessive drainage and also prevent the occurrence of poor drainage. The purpose is to reduce intracranial pressure, promote the discharge of inflammatory cerebrospinal fluid or hemorrhagic cerebrospinal fluid, clean cerebrospinal fluid, assist in the treatment of ventricular inflammation, and prevent the formation of hydrocephalus caused by fibrous adhesion. The drainage pump is fixed on the cylindrical metal rod with a T-shaped sleeve longitudinally. The drainage pump is marked with a ruler and the height can be adjusted up and down. The laser pen fixed laterally on the T-shaped sleeve is used to accurately measure the height of the patient's external auditory canal. In this way, the height of the drainage pump can be adjusted at any time when adjusting the patient's head position to prevent excessive drainage and also prevent the occurrence of poor drainage. The purpose is to reduce intracranial pressure, promote the discharge of inflammatory cerebrospinal fluid or bloody cerebrospinal fluid, clean cerebrospinal fluid, assist in the treatment of ventricular inflammation, and prevent the formation of hydrocephalus caused by fibrous adhesions; however, the above patent application directly illuminates the patient's external auditory canal with a laser pen to confirm the horizontal position and obtain the corresponding height of the drainage tube. First of all, it uses a laser pen to directly illuminate the patient's body surface, which is unsafe. Moreover, when the patient's head is adjusted, such as the head of the bed is raised, the technical solution of this application cannot directly reflect the adjusted height. The operation is complicated, and the drainage speed and drainage flow cannot be monitored. The function is single and it is difficult to solve the above series of problems.
