Drain tube for intracranial pressure monitoring

Abstract

The invention discloses an intracranial pressure monitoring drain tube and belongs to the technical field of intracranial drain tube devices. The drain tube comprises an intracranial pressure monitoring probe and a drain tube, wherein a rigid silicon rubber head is arranged at the front end of the drain tube, and a drain butt port is formed at the tail end of the drain tube; the intracranial pressure monitoring probe is embedded at the front end of the interior of the drain tube; a drain pore is formed on the lateral side of the drain tube; a rectangular hollow groove is formed in the middle of the intracranial pressure monitoring probe; a silicon substrate to which a pressure strain foil is attached is closely attached to the groove, and the periphery of the groove is completely sealed by silica gel; a first drain pore is formed on a part, corresponding to the pressure strain foil, of the top of the drain tube; and a thermocouple is arranged on the rigid silicon rubber head at the front end of the drain tube. By utilizing the intracranial pressure monitoring drain tube, the intracranial pressure is monitored in real time in an intracranial draining process, the hard silicon rubber head arranged at the front end causes less damage to brain tissues and nerve fibers; the first drain pore can be used for realizing drainage, and ensures that the pressure strain foil can be directly contacted with an external liquid, so that the monitored pressure is more accurate.

Description

technical field [0001] The invention relates to a drainage tube for monitoring intracranial pressure, which is especially suitable for real-time monitoring of intracranial pressure during intracranial drainage for patients with severe cerebral edema, and belongs to the technical field of intracranial drainage tube devices. Background technique [0002] Traumatic cerebral edema is secondary to craniocerebral injury. The increase of intracranial fluid components causes brain volume to increase. It is an important part of secondary brain damage after trauma. If it is not treated in time, it will lead to the formation of cerebral herniation and central breathing. Circulatory collapse and death. Intracranial pressure (ICP) monitoring is the most rapid, objective and accurate method for diagnosing intracranial hypertension. It is also an important means for observing changes in patients' conditions, early diagnosis, judging operation time, guiding clinical drug treatment, and judg...
