Digital pressure gauge for lumbar puncture with controllable cerebrospinal fluid

Abstract

The invention relates to the field of medical instruments, in particular to a digital pressure gauge for lumbar puncture with controllable cerebrospinal fluid. The gauge comprises a lumbar spinal needle connecting end, a cerebrospinal fluid connecting end, a pressure sensor and a numeric display meter and is characterized in that the interior of a housing of the gauge is partially narrowed to form a valve seat; the valve seat divides an inner cavity of the housing into a cerebrospinal fluid drainage cavity and a pressure detection cavity; when a valve head is closely attached to the valve seat, a channel between the cerebrospinal fluid drainage cavity and the pressure detection cavity is blocked; when the valve head is away from the valve seat, the cerebrospinal fluid drainage cavity communicates with the pressure detection cavity; and the lumbar spinal needle connecting end and the cerebrospinal fluid connecting end are arranged; and the cerebrospinal fluid connecting end is a section of 90-degree bent pipe. Compared with the prior art, the digital pressure gauge for lumbar puncture with the controllable cerebrospinal fluid has the following advantages: pressure value can be read at any time before collection of cerebrospinal fluid and during collection of cerebrospinal fluid; intracranial pressure valve after lumbar puncture can be displayed; and the digital pressure gauge can play an important role in guiding the positions and medicine use for a patient who takes a rest after lumbar puncture.

Description

technical field

[0001] The invention relates to the field of clinical medicine and medical equipment, in particular to a digital lumbar puncture manometer with controllable cerebrospinal fluid velocity and flow, which can be widely used in neurology, surgery, etc. to monitor the intracranial pressure of patients and perform lumbar puncture When taking cerebrospinal fluid. Background technique

[0002] Lumbar puncture is a diagnostic operation often performed in neurology and surgery. It is mainly used for the identification of diseases such as encephalitis, demyelinating disease, paraneoplastic syndrome, and subarachnoid hemorrhage. Important value, any imaging examination can not replace the importance of lumbar puncture. At present, the main steps of lumbar puncture are: 1) The patient lies supine with the pillow removed, bends the neck and hips, hugs the knees with both hands, and keeps the shoulders perpendicular to the bed surface; 2) Select the gap between waist 3-4 o...
