Integrated safe lumbar puncture device

Abstract

The invention discloses an integrated safe lumbar puncture device and relates to the technical field of medical apparatus and instruments. The integrated safe lumbar puncture device comprises a puncture device shell, an operating handle is formed at the lower end of the outer wall of the puncture device shell, a supporting frame is welded to the lower end of the inner wall of the puncture device shell, the top end of the supporting frame is connected with a sliding mechanism, the tail end of the sliding mechanism is connected with a cerebrospinal fluid collecting cavity, the top end of the cerebrospinal fluid collecting cavity can be connected with a sealing cap, a cerebrospinal fluid pressure tester and an injector, and collecting cup supporting plates are welded to two sides of the bottom end of the cerebrospinal fluid collecting cavity. According to the integrated safe lumbar puncture device, when a capillary needle tube is inserted into a cerebrospinal fluid extraction position, asliding block is pulled to drive a guide wire to move, so that the pressure difference exists between a puncture mechanism and the cerebrospinal fluid collecting cavity, a first switch valve is slowlyrotated to enable the puncture mechanism to start to communicate with the cerebrospinal fluid collecting cavity, cerebrospinal fluid starts to slowly flow into the cerebrospinal fluid collecting cavity, and various complications such as cerebral hernia are not prone to being generated because of the gentle process.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an integrated safety lumbar puncture device. Background technique [0002] With the development of science and technology and the progress of the times, the equipment involved in the medical industry is increasingly pursuing refinement and efficiency. Lumbar puncture is a routine bedside diagnosis and treatment operation in neurosurgery, neurology, and pediatric neurosurgery. For the laboratory examination of cerebrospinal fluid samples, the pressure test of cerebrospinal fluid is often required during the puncture process. In this case, the lumbar puncture device was invented to extract cerebrospinal fluid and perform cerebrospinal fluid pressure test. [0003] Existing lumbar puncture devices are usually relatively simple in structure and relatively single in function. They can only be used to extract cerebrospinal fluid, and cannot immediately detect the pressure or st...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the existing lumbar puncture device is usually relatively simple in structure and relatively single in function, and can only be used to extract cerebrospinal fluid, and cannot immediately detect the pressure or store the extracted cerebrospinal fluid, and if the cerebrospinal fluid is extracted, if the operation Unsteady force of personnel can easily cause various complications such as brain herniation in patients, and the existing lumbar puncture device often only relies on the operator's feeling and experience to judge whether the puncture position is accurate, and cannot be accurate. Judgment, the disadvantages of greatly increasing the risk of accidents, and proposed a one-piece safety lumbar puncture device
