Specific embodiment
The utility model is described in detail With reference to embodiment.
Utility model device includes lumbar puncture stylophore 1, is marked with scale on lumbar puncture stylophore 1, for marking inserting needle
Depth.The cerebrospinal fluid displacement outlet 2 that the rear portion dextrad side of lumbar puncture stylophore 1 is opened, connects three-way connection 3 herein, can
The open direction of adjustment threeway as needed, causes 3 Single port of three-way connection for flowing out cerebrospinal fluid (or inner theca transfusion), another port
For connecing cerebral table or pressure-measuring pipe, physiological saline injection rate can be adjusted according to cranium pressure.The tail end of lumbar puncture stylophore 1 is by elasticity
Rubber blocks pad 4 and blocks, and rubber, which blocks 4 center of pad, hole, positive can be rinsed by puncture needle core 5 and cerebrospinal fluid displacement by the hole
Thus device 6, hole enclosed elastic when obstructed, cerebrospinal fluid cannot be leaked out inversely, air cannot also drive in the wrong direction into internal.Cerebrospinal fluid
Slow rinse device 6 is a kind of needle-shaped, hollow metal objects, and head end is equipped with several holes, and tail end is connected by PVC connecting tube 7
Large capacity syringe 8, for being injected into physiological saline exchange cerebrospinal fluid into cavum subarachnoidale, outside cerebrospinal fluid displacement flusher 6
Diameter is less than the outer diameter of 1 internal diameter of lumbar puncture stylophore and puncture needle core 5.Liquid switch folder 9, cerebrospinal fluid are additionally provided in PVC connecting tube 7
It needs that puncture needle core 5 is first extracted lumbar puncture stylophore 1 when displacement, is closed after cerebrospinal fluid displacement flusher 6 is vented with physiological saline
Liquid switch folder 9 is closed, cerebrospinal fluid displacement flusher 6 is fully inserted into lumbar puncture stylophore 1 simultaneously by the hole that rubber blocks pad 4
Root is locked, only needs unidirectionally, at the uniform velocity to inject by cerebrospinal fluid displacement flusher 6 to cavum subarachnoidale using large capacity syringe 8
Physiological saline is not necessarily to pumpback cerebrospinal fluid.After physiological saline injects cavum subarachnoidale by cerebrospinal fluid displacement flusher 6, respective volume
Cerebrospinal fluid (or cerebrospinal fluid dilution) then driven in the wrong direction by gap and flow out from cerebrospinal fluid displacement outlet 2, and then cerebrospinal fluid is discharged
In vitro, entire cerebrospinal fluid displacement process is since discrepancy amount is in a basic balance, cranium pressure fluctuation is small, and easy to operate, displacement efficiency is high, every time
Replacement amount is big, and operation is relatively closed, and patient's tolerance is good.
Patient's routine lateral position, sets lumbar puncture art position, and routine disinfection drape selectes lumbar puncture gap, part
Anesthesia, is fully inserted into lumbar puncture stylophore 1 and locks root for puncture needle core 5, cerebrospinal fluid displacement outlet 2 connects three-way connection
3, conventional waist is worn under 1 scale of lumbar puncture stylophore auxiliary, is pulled out puncture needle core 5 after having breakthrough to feel, is seen that cerebrospinal fluid is connected by three
First 3 wherein Single port outflow prompt punctures successfully, closes three-way connection 3 immediately and avoids excessive cerebrospinal fluid by threeway port flow
Out, three-way connection 3 wherein connects pressure measuring unit (cerebral table or pressure-measuring pipe) on Single port, and adjustment threeway, which is directed toward, surveys cranium pressure (first pressing),
Appropriate cerebrospinal fluid is released according to cranium pressure situation adjustment threeway direction, threeway is adjusted again and is directed toward, lay down pressure measuring unit, prepare brain
Spinal fluid displacement.6 tail end of cerebrospinal fluid displacement flusher is connect to the large capacity syringe 8 for pumping full physiological saline, cerebrospinal fluid displacement is rushed
Closing liquid switch folder 9 after device 6 is vented with physiological saline is washed, it is single into cerebrospinal fluid displacement flusher 6 from large capacity syringe 8
To, at the uniform velocity injecting normal saline, while the direction of three-way connection 3 is adjusted, makes the cerebrospinal fluid being displaced by side cerebrospinal fluid displacement
2 equivalent of outlet at the uniform velocity excretes, and plays the role of rinsing cavum subarachnoidale, cerebrospinal fluid displacement.
After reaching cerebrospinal fluid displacement target dose according to the state of an illness, end can be surveyed and press (method is same as above), during cerebrospinal fluid displacement also
The adjustable direction of three-way connection 3 surveys cranium pressure at any time；Also it can adjust three-way connection 3 and be directed toward intrathecal injection drug.Cerebrospinal fluid displacement knot
Shu Hou, it is whole to pull out lumbar puncture stylophore 1 and cerebrospinal fluid displacement flusher 6 together.It is suitably firmly pressed using aseptic dressing
It presses, push away and rub point of puncture a moment, aseptic dressing wraps up fixed puncture orifice, and art finishes.Cerebrospinal fluid displacement is preoperative to pump full 50ml physiological saline
It is connected to 6 tail end of cerebrospinal fluid displacement flusher, corresponding saline volume is unidirectionally pushed into according to expected exchange cerebrospinal fluid amount, no longer needs to take
Lower syringe, easy time saving, reduction infection risk.
The utility model is closed-loop operation, and cerebrospinal fluid displacement is easy to operate, it is only necessary to which the unidirectional injecting normal saline of syringe is
Can, it is not necessarily to pumpback cerebrospinal fluid, entire cerebrospinal fluid displacement process is easy to operate since discrepancy amount is in a basic balance, cranium pressure fluctuation is small, sets
Change high-efficient, each replacement amount is big, operates relatively closed, and patient's tolerance is good, and secondary infection risk is low, and purposes multiplicity can be stayed
Set samples of CSF, monitoring cranium pressure, intrathecal injection, or even Lumbar cistern tube can be assisted etc..
The above is only the better embodiment to the utility model, not makees any form to the utility model
On limitation, all any simple modifications made to embodiment of above according to the technical essence of the utility model are equivalent to become
Change and modify, is all within the scope of the technical scheme of the utility model.
