Intracranial ommaya capsule puncture drainage needle

Abstract

A puncture drainage needle for intracranial ommaya sac, including a puncture needle, a pressure sensor, a flow sensor and a drainage connection tube, the puncture needle is connected to the drainage tube, and two lumen channels are arranged inside the puncture needle, one of which is a pressure probe and a drainage tube. The pressure sensor is connected to the channel through the conduction line channel, and the other lumen is the fluid drainage channel; the flow sensor is placed on the drainage tube with an adjustment knob; the puncture needle is divided into an intracranial section and an extracranial section, and the two sections are connected by an arc corner; There is a needle tip side hole in the needle tip of the segment, and a double needle wing structure is installed on the extracranial segment. The needle tube of the extracranial segment is connected with a drainage tube, and a pressure sensor, a flow sensor, and a medical three-way tube are installed on the drainage tube. The present invention can efficiently puncture the intracranial ommaya sac, adjust the drainage velocity of hemorrhage or cerebrospinal fluid, monitor intracranial pressure, ensure the smoothness of the pipeline, and provide dynamic monitoring for the treatment of patients with hemorrhage or hydrocephalus, which is beneficial to the prognosis of patients and treatment.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a puncture and drainage needle for an intracranial ommaya sac. Background technique [0002] Ventricular hemorrhage is a severe type of cerebral hemorrhage. Due to hemorrhage, cerebrospinal fluid circulation is disturbed. Acute hydrocephalus causes intracranial pressure to rise sharply in a short period of time, compressing brain tissue, high mortality rate, and poor prognosis. The current treatment method uses ommaya Capsule implantation can remove hematoma and reduce intracranial pressure through external puncture and drainage. Clinically, medical personnel achieve the purpose of drainage by puncturing with bent infusion needles, but in reality, the probability of poor drainage is very high, and the intracranial pressure cannot be monitored, which seriously affects the treatment of medical personnel and affects the prognosis of patients. And take up a large...
