Description

Technical Field

[0001] The invention relates to the technical field of neurosurgery, and in particular to a neurosurgery drain with a cleaning function. Background Art

[0002] Neurosurgery is mainly responsible for diseases of the brain, spinal cord and other nervous systems caused by trauma, such as life-threatening cerebral hemorrhage, brain trauma caused by car accidents, or brain tumor compression requiring surgical treatment. In the neurosurgery departments of major hospitals, a large amount of effusion (blood or liquid medicine, etc.) may be produced during the treatment of patients with brain tumors, severe intracranial injuries and hypertensive cerebral hemorrhage. It is often necessary to use a drainage device to drain the effusion (blood or liquid medicine, etc.) exuded from the patient's head. When using the existing drainage device, the drainage head is usually placed at the part that needs drainage, and then the negative pressure pump is turned on to make the air pressure in the drainage bottle lower than the external air pressure. The external air pressure presses the effusion from the drainage head through the connecting tube into the drainage bottle, thereby achieving drainage. The effusion drained into the drainage bottle by negative pressure is generally adhered to the inner wall of the drainage bottle after being discharged through the drainage tube. For this reason, medical staff need to clean the drainage bottle after the drainage is completed to ensure that the drainage bottle is clean before it can be put into use next time. Most of the existing drainage devices cannot be cleaned inside. When cleaning after use, medical staff need to manually clean the drainage bottle with a brush, which results in incomplete cleaning and poor cleaning effect. It also wastes the time of medical staff, especially doctors with medical treatment ability, and cannot give full play to their role, which is very inconvenient to use. Based on this, we propose a neurosurgical drain with cleaning function to solve the above problems. Summary of the invention

The first knocking ball 410 moves back and forth to vibrate and knock the annular cleaning plate 215 and the circular cleaning plate 214 by knocking the outer wall of the mounting ring 48 back and forth, so that the residual effusion adhered by the cleaning brush on the annular cleaning plate 215 and the circular cleaning plate 214 is vibrated and removed, thereby improving the cleaning effect of the cleaning brush on the residual effusion; at the same time, the second knocking ball 411 moves back and forth to knock and vibrate the inner wall of the drainage bottle 2, thereby improving the cleaning effect of the cleaning brush on the residual effusion adhered to the inner wall of the drainage bottle 2, thereby increasing the practicality of the device; After cleaning is completed, open the drain pipe 104 to drain the waste liquid.

[0020] The present invention provides a reciprocating mechanism, which enables the cleaning brush to reciprocate up and down to scrape and clean the inner wall and the bottom wall of the drainage bottle, thereby preventing the accumulated fluid residue from adhering to the inner wall of the drainage bottle. After use, the medical staff still needs to manually clean the drainage bottle with a brush, which leads to incomplete cleaning, poor cleaning effect, and a waste of time for the medical staff. The rotating mechanism is provided, which enables the cleaning brush to reciprocate up and down to scrape and clean the inner wall and the bottom wall of the drainage bottle, while the reciprocating rotation of the cleaning brush increases the cleaning effect of the accumulated fluid residue adhering to the inner wall and the bottom wall of the drainage bottle, ensuring that the drainage bottle can be put into use next time only after it is cleaned. The whole process improves the work efficiency of the medical staff and the cleaning effect of the drainage bottle. The knocking mechanism is provided, which achieves the cleaning effect. The cleaning brush moves back and forth up and down to scrape and clean the inner wall and the bottom wall of the drainage bottle, and the cleaning brush rotates back and forth to increase the effect of cleaning the residual accumulated liquid adhering to the inner wall and the bottom wall of the drainage bottle. At the same time, the first knocking ball moves back and forth to vibrate and knock the annular cleaning plate and the circular cleaning plate by knocking back and forth on the outer wall of the mounting ring, so that the residual accumulated liquid adhering to the cleaning brush on the annular cleaning plate and the circular cleaning plate is vibrated and cleaned, thereby improving the cleaning effect of the cleaning brush on the residual accumulated liquid; at the same time, the second knocking ball moves back and forth to knock and vibrate the inner wall of the drainage bottle, thereby improving the cleaning effect of the cleaning brush on the residual accumulated liquid adhering to the inner wall of the drainage bottle, thereby increasing the practicability of the device; the structure of the present invention is simple and reliable, the cleaning effect of the drainage bottle is good, the control is convenient, and it is suitable for popularization.
