Embodiment Construction

[0019] Such as figure 1 As shown, the disposable cerebrospinal fluid external drainage device of the present invention includes a drainage catheter 1 , a connecting pipeline 2 , and a drainage bag 3 connected in sequence. Wherein, the connecting pipeline 2 is connected with a two-way three-way valve 4 and a flow regulating valve 5 . The two-way three-way valve 4 has a sampling port 6 and a pressure monitoring port 7, and the sampling port 6 and the pressure monitoring port 7 are provided with protective caps to prevent contamination when not in use.

[0020] A fixing clip 10 is provided on the outer wall of the drainage catheter 1 .

[0021] The flow regulating valve 5 is a precision flow regulating valve.

[0022] combine figure 2 , image 3 Before using the present invention, the drainage catheter 1 is first connected to the trocar 11, and the inner cavity of the drainage catheter 1 is flushed with physiological saline, and the trocar 11 is removed after flushing, and t...

Abstract

The invention relates to a disposable external drainage apparatus for cerebrospinal fluid, which belongs to the technical field of clinical cerebrospinal fluid drainage apparatuses for patients and comprises a drainage catheter, a connecting pipe and a drainage bag connected in sequence, wherein the connecting pipe is connected with a three-way dual-valve and a flow regulating valve. When in drainage, the disposable external drainage apparatus for cerebrospinal fluid is capable of controlling drainage rate accurately. Meanwhile, since the disposable external drainage apparatus for cerebrospinal fluid is provided with a sampling port and a pressure monitoring port, variation of intracranial pressure of patients can be monitored continuously dynamically.

Description

technical field [0001] The invention relates to a disposable external drainage device for cerebrospinal fluid, which belongs to the technical field of clinical cerebrospinal fluid drainage device for patients. Background technique [0002] Clinically, external cerebrospinal fluid drainage (also known as lumbar cistern drainage) is a safe, effective, and minimally invasive method for treating neurosurgical diseases such as cerebrospinal fluid leakage, intracranial infection, and subarachnoid hemorrhage. It is suitable for the treatment of severe craniocerebral injury postoperative and traumatic subarachnoid hemorrhage, various intractable cerebrospinal fluid otorrhea, rhinorrhea, and incision leakage, intracranial infection, intractable subcutaneous effusion, and communicating hydrocephalus. Better curative effect. [0003] During the continuous drainage of cerebrospinal fluid, how to accurately control the drainage speed and volume of cerebrospinal fluid is a difficult prob...
