Description

Technical Field

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

[0002] In the actual treatment of neurosurgery patients, drainage of hydrocephalus is a common operation. Drainage of hydrocephalus can reduce intracranial pressure. Excessive intracranial pressure can easily cause bleeding and cause irreversible damage to the patient's brain. At present, most common drainage devices use an ommaya bag installed on the drainage tube. The ommaya bag is placed on the patient's skull. When puncture sampling is required, the ommaya bag is directly punctured by a syringe to take samples. It is widely used due to its flexible use and other advantages. When the patient stands up, the current drainage device often requires manual control of the valve closure, and the automation effect is not good. Once forgotten, it is easy to cause safety hazards such as reflux of effusion, and the drainage safety is not good. At the same time, the ommaya bag and other methods are not stable enough for installation and are prone to movement, which drives the drainage blind tube to move in the brain, which is easy to damage the brain. It is not convenient to automatically alarm when the pipe is pulled. At the same time, after multiple punctures, the ommaya bag has too many pinholes on the surface, which is prone to leakage, inconvenient to seal, and has a poor service life.

The structure has direct detection and accurate control, and adopts multi-angle rotatable drainage installation ball 601 to make the detection direction more comprehensive. The length of drainage pipe 602 is set according to the demand. Drainage pipe 602 is a hose. When drainage pipe 602 is pulled to any side, drainage pipe 602 drives drainage installation ball 601 to rotate and squeezes detection sliding column 701. Alarm light 103 will light up to alert the caregiver and prevent further dragging to cause more serious injury.

[0037] The working principle of this embodiment is as follows: first, a through hole is drilled on the skull of the patient, and then six positioning grooves are drilled on the outside of the through hole without penetration. The drainage blind tube 202 is inserted into the brain for drainage, and the threaded connection port 1011 is screwed into the through hole of the skull. During the process, the rotating ring 201 is adapted to rotate inside the threaded connection port 1011, and then the positioning conical column 304 on the positioning ring 302 is pressed down by rotating the limit push ring 301, and fits on the skull for tightening. During the process, the sealing airbag ring 303 will also fit on the skull for sealing protection. The needle of the syringe is inserted into the suction rubber ring 402. At this time, the cerebrospinal fluid can be suctioned. After the suction is completed, the needle is removed, and the rotation push cylinder 403 squeezes the suction rubber ring 402 can realize the extrusion and suction rubber ring 402 to shrink inwards, and realize the through hole in the middle of the closed suction rubber ring 402. When the patient is in a lying position, the blocking ball 502 will roll from the inclined mounting tube 501 to the magnetic ring 503 under the action of its own weight, and the magnetic ring 503 can magnetically attract the limited blocking ball 502. At this time, the cerebrospinal fluid can normally flow from the drainage mounting shell 101 into the detection and drainage part 6 for discharge. When the patient stands up, the skull connecting part 1 is driven to stand up, and the mounting tube 501 is also driven to stand up. Under the action of the blocking ball 502's own weight, the magnetic force of the magnetic ring 503 is not enough to absorb the blocking ball 502, and the blocking ball 502 can naturally fall and block the inner side of the mounting tube 501 to prevent the effusion from flowing back.

[0038] During clinical use, when the drainage tube 602 is pulled, the drainage tube 602 drives the drainage mounting ball 601 to rotate, and the positioning groove 6011 on the drainage mounting ball 601 will be misaligned with the detection sliding column 701. As long as the misalignment occurs, the arc groove structure of the positioning groove 601 will squeeze the detection sliding column 701. Once the detection sliding column 701 is squeezed and moved beyond the standard distance, it will drive the power-connecting spiral guide wire 703 on the detection sliding column 701 to contact the power-connecting block 704, and the alarm light 103 will light up to alarm and provide a prompt. The detection direction is comprehensive and safety is improved.
