Intracranial ommaya capsule puncture drainage needle

Abstract

An intracranial ommaya capsule puncture drainage needle comprises a puncture needle, a pressure sensor, a flow sensor and a drainage connecting tube, the puncture needle is connected with the drainage tube, two tube cavity channels are formed in the puncture needle, one tube cavity is a connecting channel of a pressure probe and the pressure sensor through a conduction line channel, and the other tube cavity is a liquid drainage channel; the flow sensor is arranged on the drainage tube and provided with an adjusting rotary knob; the puncture needle is divided into an intracranial section and an extracranial section which are connected through an arc corner; needle tip side holes are formed at the needle tip part of the intracranial section, and two-needle-wing structure is arranged on the extracranial section, a needle tube of the extracranial section is connected with the drainage tube, and the pressure sensor, the flow sensor and a medical T-branch tube are installed on the drainage tube. By means of the intracranial ommaya capsule puncture drainage needle, the intracranial ommaya capsule can efficiently puncture, the drainage speed of ventricular hematocele or cerebrospinal fluid is adjusted, the intracranial pressure is monitored, it is ensured that the tube is not blocked, dynamic monitoring is provided for patients suffering from ventricular hematocele or hydrocephalus, and the prognosis and treatment of the patients are facilitated.

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...

Problems solved by technology

Clinically, medical personnel achieve the purpose of drainage by puncturing with bent infusion needles, but in reality, the probability of poor drainage is extremely 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 lot of time for medical staff to deal with the problem of blocked tubes
