Problems solved by technology

Although it has a simple structure and good safety performance, because it injects medicine and extracts body fluids through the liquid inlet catheter, and discharges body fluids through the liquid outlet catheter, it is not in line with the operating habits of medical staff, and there will still be increased pollution, The problem of repeated operations, therefore, the operation is still not safe and easy

Embodiment Construction

[0020] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0021] like figure 1 , 6 Or as shown in 8, the present invention includes needle tube 1 and needle mouth cover 2, is characterized in that: needle mouth cover 2 is arranged as a three-way, and this three-way is that the needle mouth cover 2 is provided with all communicated with needle tube 1 medicine feeding The channel 3 and the liquid discharge detection channel 4 are also provided with a control valve 5 which enables the needle tube 1 to communicate with the medicine feeding channel 3 and the liquid discharge detection channel 4 .

[0022] The present invention is used in the following way: the needle tube is punctured on the patient, and after the lumbar puncture is successful, the needle tube 1 is communicated with the liquid discharge detection channel 4 through the control valve 5. The outflowing cerebrospinal fluid can be obtained through the drain...

Abstract

A cerebrospinal fluid displacing device is composed of needle tube and needle jointer with a three-way unit (needle tube channel, medicine feeding channel and discharged fluid examining channel) and a control valve.

Description

(1) Technical field [0001] The invention relates to a medical device, in particular to a device for replacing cerebrospinal fluid. (2) Technical background [0002] Cerebrospinal fluid replacement is widely used in the diagnosis and treatment of neurological diseases. What the existing replacement (cerebrospinal fluid) device generally adopts is a lumbar puncture needle, and this lumbar puncture needle includes a needle tube, a needle mouth cover and a needle core. Medical personnel usually use it like this: after the lumbar puncture is successful, the needle core needs to be pulled out, and then the flow rate of the cerebrospinal fluid is observed, or the pressure measuring tube is connected to detect the pressure of the cerebrospinal fluid. If cerebrospinal fluid replacement is to be performed, first, use a syringe to draw a certain amount of required replacement fluid (normally 0.9% saline), then pull out the needle core, and then connect the syringe to the lumbar punctu...
