Description
Technical field
This utility model belongs to medical aid tool field, relates to a kind of improvement lumbar puncture needle particularly, has structure simple, operating process simplifies convenient, and decreasing pollution probability, can control csf flow speed, the advantages such as monitor cerebral SFP constantly, can insert epidural catheter, applied widely.
Background technology
Current lumbar puncture needle is made up of needle tubing and built-in nook closing member, and during puncture after needle point enters spinal epidural cavity, built-in nook closing member is extracted out in lumbar puncture needle, when puncturing unsuccessful, will repeatedly extract and insert the nook closing member adjustment lumbar puncture needle degree of depth out, operating process is loaded down with trivial details, also can increase pollution probability.When intracranial pressure is large, extracting nook closing member process cerebrospinal fluid out can flow out rapidly, causes cerebral tissue to offset downward, very easily cerebral hernia occurs, crisis life.As everyone knows, some patient's waists are worn unsuccessful several times, and these cause suffering to patient, and the loaded down with trivial details operation of medical personnel also cannot solve.So it is simple to develop a kind of structure, operating process simplifies convenient, and the lumbar puncture needle of the advantages such as decreasing pollution probability, can control csf flow speed, constantly monitor cerebral SFP, can insert epidural catheter, applied widely is the task of top priority.
Summary of the invention
It is simple that the purpose of this utility model is to provide a kind of structure, and operating process simplifies convenient, the lumbar puncture needle of the advantages such as decreasing pollution probability, can control csf flow speed, constantly monitor cerebral SFP, can insert epidural catheter, applied widely.
The technical solution adopted in the utility model is: sat by needle tubing and pin and form, needle point pin cutting edge of a knife or a sword dorsal part is provided with aperture, and pin is sat outer end and is provided with external tapping.
Above-mentioned one improves lumbar puncture needle, it is characterized in that: external tapping connecting hose taken by pin, flexible pipe and pressure-measuring pipe and drainage tube are controlled by three-way valve, and pressure-measuring pipe is connected with pressure experience table, drainage tube is provided with plug, and plug can be connected syringe or directly drain cerebrospinal fluid.
Above-mentioned one improves lumbar puncture needle, and the flexible pipe that external tapping connects can pull out, and insert epidural catheter by external tapping, epidural catheter is passed by needle point aperture and enters spinal epidural cavity.
The beneficial effects of the utility model are: 1. this utility model is owing to changing the structure of lumbar puncture needle, without the need to placing nook closing member in needle tubing, needle point pin cutting edge of a knife or a sword place closes, inserting needle channel organization can not be damaged when inserting needle, during puncture after needle point enters spinal epidural cavity, needle point pin cutting edge of a knife or a sword dorsal part aperture smoothness can drain cerebrospinal fluid.2. in needle tubing, nook closing member is not set, avoids and insert and extract out nook closing member troublesome operation process, decrease pollution probability.When intracranial pressure is large, during extraction nook closing member, cerebrospinal fluid can flow out rapidly, causes cerebral tissue to offset downward, very easily cerebral hernia occurs, crisis life.3. needle tubing external tapping is by soft pipe connection three-way valve, and during puncture, external tapping switch cuts out, after puncture needle enters spinal epidural cavity, drainage tube switch opens, control the flow velocity of drainage of cerebrospinal fluid, open pressure-measuring pipe switch afterwards, pressure experience table can monitor cerebral SFP constantly.This device prevents cerebrospinal fluid from losing rapidly, causes the danger of cerebral hernia, and can understand cerebral situation constantly, also can treat through drainage tube injection of medicine.4. when needs place epidural catheter time, by external tapping insert epidural catheter, epidural catheter is passed by needle point aperture, enter spinal epidural cavity and indwelling in intracavity, extract lumbar puncture needle afterwards.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Embodiment one improves lumbar puncture needle
As shown in Figure 1, a kind of improvement lumbar puncture needle, sit (2) by needle tubing (1) and pin to form, needle point pin cutting edge of a knife or a sword dorsal part is provided with aperture (3), needle point pin cutting edge of a knife or a sword place closes, can not damage inserting needle path tissue when inserting needle, during puncture after needle point enters spinal epidural cavity, needle point pin cutting edge of a knife or a sword dorsal part aperture smoothness can drain cerebrospinal fluid.Pin is sat (2) outer end and is provided with external tapping (4).
External tapping (4) connecting hose (5) taken by pin, flexible pipe (5) is controlled by three-way valve (7) with pressure-measuring pipe (6) and drainage tube (8), pressure-measuring pipe (6) is connected with pressure experience table (10), can monitor cerebral SFP constantly, drainage tube (8) is provided with plug (9), and plug (9) can be connected injector to inject Drug therapy or directly drain cerebrospinal fluid laboratory examination.
The flexible pipe (5) that external tapping (4) connects can pull out, epidural catheter (11) is inserted by external tapping (4), epidural catheter (11) is passed by needle point aperture (3) and enters spinal epidural cavity, extract lumbar puncture needle afterwards, epidural catheter is retained in spinal epidural cavity.Its function is when epidural anesthesia needs indwelling epidural catheter, can pass through this kind of lumbar puncture needle complete operation.
Using method: 1, operation is front by external tapping connecting hose, closes flexible pipe, pressure-measuring pipe and drainage tube switch that three-way valve connects.2, lumbar puncture is carried out routinely, after needle tubing needle point enters spinal epidural cavity, first the hosepipe switch of three-way valve is opened, slowly open drainage tube switch afterwards, open drainage tube plug, observe and whether flow out cerebrospinal fluid, as flowed out without cerebrospinal fluid, judge that needle point may not at spinal epidural cavity, close drainage tube switch, the adjustment needle tubing degree of depth and position are until needle point enters spinal epidural cavity, slowly open drainage tube switch again, drainage tube flows out a small amount of cerebrospinal fluid, now judge to puncture successfully, the drainage tube switch of rapid closedown three-way valve, cerebrospinal fluid is prevented to run off, the a small amount of cerebrospinal fluid flowed out can be used for laboratory examination.3, pressure-measuring pipe switch is opened, by pressure experience table monitor cerebral SFP constantly.4 when needs epidural intracavity injection of medicine chemotherapy or other treatment, by drainage tube plug syringe injection of medicine.5, when epidural anesthesia needs indwelling epidural catheter, pull out flexible pipe, epidural catheter is inserted needle tubing through external tapping, passed by needle point aperture and enter spinal epidural cavity, extract lumbar puncture needle afterwards, epidural catheter is retained in spinal epidural cavity.
