Integrated safe lumbar puncture device

Abstract

The invention discloses an integrated safe lumbar puncture device used clinically. The integrated safe lumbar puncture device is mainly applied to the conditions that cerebrospinal fluid puncture needs to be conducted in the clinical diagnosis and treatment process, for example, the cerebrospinal fluid pressure test is conducted during lumbar puncture as well as a cerebrospinal fluid sample is remained to perform laboratory examination. The integrated safe lumbar puncture device is characterized in that the traditional lumbar puncture needle can be replaced; the cerebrospinal fluid pressure test can be realized in the same device; the cerebrospinal fluid sample is remained according to the requirement and intrathecal injection is conducted; cerebral hernia caused by high cranial pressure excessive drainage in the lumbar puncture process can be avoided; the operation processes of sample retention, pressure test and intrathecal injection can be completed in the same device; the operationflow is simplified; puncture complications are avoided; and the safety of patients and operators is guaranteed.

Description

technical field [0001] The invention relates to a clinically used integrated safety lumbar puncture device, which is mainly used in the pressure test of cerebrospinal fluid during lumbar puncture, as well as taking samples of cerebrospinal fluid for laboratory examination, etc. It is characterized in that it can replace the traditional lumbar puncture Needle, can realize cerebrospinal fluid pressure test in the same device, take cerebrospinal fluid samples according to needs, intrathecal injection, realize sample retention, pressure test, intrathecal injection and other operations in the same device, avoiding the lumbar puncture process due to Cerebral herniation caused by high intracranial pressure and excessive drainage, simplifying the operation process, ensuring the safety of patients and operators, belongs to the field of clinical diagnosis and treatment. Background technique [0002] Clinically, lumbar puncture is a routine bedside diagnosis and treatment operation in ...

AI Technical Summary

Problems solved by technology

In addition, in the absence of a glass manometry tube, it may be necessary to roughly interpret intracranial pressure by counting cerebrospinal fluid drops

The above method is cumbersome to operate, and the long exposure time of cerebrospinal fluid increases the risk of infection. In some patients with intracranial hypertension, due to poor control of cerebrospinal fluid outflow, sudden foramen magnum hernia may occur, resulting in severe respiratory and cardiac arrest. complication

[0004] In addition, the traditional lumbar puncture needle needs to be returned after pulling out the inner core of the puncture needle, collecting cerebrospinal fluid and measuring pressure. Some difficulty, often resulting in excess CSF loss

At present, there is no lumbar puncture device that can solve the above problems at the same time.
