Drainage device for intracranial hematoma cranium drilling

Abstract

A drainage device for intracranial hematoma cranium drilling is characterized by comprising a double-cavity catheter, a drainage tube, a dredging balloon, a drainage bag and a reverse flowing prevention tee joint. The double-cavity catheter is provided with a first tube cavity and a second tube cavity, wherein the first tube cavity and the second tube cavity are mutually isolated, the first tube cavity is used for drainage and connected with the drainage tube, and the second tube cavity is used for medicine injection and flushing and connected with an injection tube. The double-cavity catheter is arranged, so that drainage, flushing, and medicine injection are performed in different channels, it is guaranteed that the channels are kept sanitary and clean, and intracranial infection is prevented. The reverse flowing prevention tee joint is used for preventing hydrops from flowing reversely so that secondary infection and danger can be prevented. Scales are arranged on the drainage tube and the drainage bag, the dredging balloon is connected with an air pressure adjusting assembly, and the scales and the air pressure adjusting assembly are arranged, so that it is avoided that the operation force can not be mastered due to insufficient experience, and operation stability is improved. In addition, the drainage device is further provided with a dropping bottle and the dredging balloon, so that the channels are convenient to observe and prevented from being blocked.

Description

[0001] 【 Technical field] [0002] The present invention relates to medical equipment, in particular to an intracranial hematoma drilling and drainage device. 【Background technique】 [0003] Intracerebral hemorrhage is a disease with a very high mortality rate. In recent years, the number of cases has been on the rise, and the age of onset is getting younger and younger. Intracerebral hemorrhage not only has a high fatality rate, but also ranks first among all brain diseases in terms of disability rate. A small amount of intracerebral hemorrhage can be treated conservatively, and the treatment of intracerebral hemorrhage larger than 30 ml supratentorial and 10 ml infratentorial has always been an important topic in neurosurgery research. Such as decompression of large bone craniectomy, large bone window, small bone window, and microsurgery and endoscopic surgery carried out in recent years. Although these existing methods can remove intracranial hematoma under direct visio...

Problems solved by technology

[0005] Drainage device is a necessary device for burr hole drainage of intracranial hematoma. At present, the drainage tube used clinically is mainly ventricle drainage tube, which has thin side holes, few side holes, and short distribution distance, which easily leads to blockage of drainage holes and poor drainage. , such as puncture and drainage in the direction of the long axis, because the total distance of the arrangement of side holes is too short, it cannot be fully drained

In addition, the existing drainage devices do not have a flow rate control valve. After the catheter is successfully inserted, the suction force during drainage is usually controlled by the doctor due to the high intracranial pressure. If the doctor has insufficient puncture experience and poor force control, it is easy to Rebleeding and damage to brain tissue due to excessive suction force, and too fast drainage can easily cause intracranial pressure to drop too quickly, which can easily lead to hemorrhage or brain herniation

In order to prevent this from happening, physicians usually clamp the drainage tube directly with hemostatic forceps. This method is likely to cause damage or rupture of the drainage tube, and a new tube needs to be placed, causing re-trauma to the patient.

On the other hand, the existing drainage tubes are usually single-lumen, and drainage, flushing, and drug injection must be carried out in a single lumen, so it is easy to reinject drainage materials, air, etc. into the brain and cause retrograde infection

In addition, since there is no special dredging pipe, the drainage tube can only be squeezed continuously during dredging, so the drainage tube may be pulled out or the drainage tube may be broken during the squeezing process, posing a safety hazard

On the other hand, there is no scale on the existing drainage tube, which cannot accurately understand the intracranial pressure

And when existing intracranial drainage, drop bottle 50 is not provided, can only understand through whether there is fluctuation in the drainage tube during observation, once the fluctuation in the drainage tube is not obvious, it is difficult to find whether there is drainage flow out, and the drainage speed cannot be intuitively understood
