Description

The lumbar puncture indwelling casing tube

[technical field]

This utility model relates to the auxiliary disposable product of a kind of medical treatment, particularly a kind of inlying catheter that is applicable to after the lumbar puncture.

[background technology]

Artificial cerebrospinal fluid displacement is used in treatment for subarachnoid hemorrhage, side, constitutional chamber or intravetricular hemorrhage, purulent meningitis, tuberculous meningitis and viral meningoencephalitis usually, for avoid every day or the next day repeated multiple times carry out lumbar puncture, alleviate the sufferer misery, the clinical in recent years lumbar puncture inlying catheter of bringing into use carries out cerebrospinal fluid constant drainage or displacement.Present lumbar puncture inlying catheter mostly is following structure: a cavity drainage tube is kept somewhere in subarachnoid space by the lumbar puncture needle nook closing member, threeway of the terminal connection of drainage tube, be connected with drainage device respectively at flushing device, close sluice way during flushing, close the flushing road during drain.Though this kind lumbar puncture inlying catheter has avoided repeatedly waist to wear, and still has the following disadvantages in the practical operation: 1. can not carry out drain and flushing simultaneously, can't in time clear up local metabolite behind the brain tissue impairment, alleviate the secondary brain injury; When 2. washing, flushing liquor causes local pressure to increase; 3. wash and be vulnerable to the cerebrospinal fluid pollution.

[summary of the invention]

Technical assignment of the present utility model is at above the deficiencies in the prior art, and providing a kind of can wash and drain simultaneously, and the lumbar puncture inlying catheter that can not cause the flushing road to pollute.

The technical scheme in the invention for solving the technical problem is: a kind of lumbar puncture indwelling casing tube, it is characterized in that: comprisesyringe pipe 1,drainage tube 2, wherein, the hollow hoses that describedsyringe pipe 1 is made for medical silica-gel, body is provided withinterlayer chamber 3,interlayer chamber 3 front end outer walls are provided with one or more flushingholes 4, andinterlayer chamber 3 ends haveflusher coupling 5; Describeddrainage tube 2 hollow bodys aresluice way 6, andsluice way 6 front are to having one ormore conduction holes 7.

Above-mentioneddrainage tube 2 is made by medical grade silicon rubber.

Above-mentioneddrainage tube 2 inwalls are provided with brace rod, and being radially, spiral distributes.

Above-mentionedsluice way 6 ends have a three-way valve 8, connect a pressure-measuring pipe and a drainage system respectively.。

Above-mentionedflushing hole 4,conduction hole 7 are circular hole, square hole or strip hole.

Above-mentionedsyringe pipe 1,drainage tube 2 ends have length mark.

Compared with prior art, this utility model can wash and drain simultaneously, can not have influence on intracranial pressure, can not cause the flushing road to pollute simultaneously.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is an a-a cross-sectional view of the present utility model.

[specific embodiment]

Below in conjunction with specification drawings and specific embodiments this utility model is further specified.

As shown in Figure 1, 2, this utility model comprisessyringe pipe 1,drainage tube 2.

Wherein, the hollow hoses that describedsyringe pipe 1 is made for medical silica-gel, body is provided withinterlayer chamber 3, andinterlayer chamber 3 front end outer walls are provided with one or more flushingholes 4, andinterlayer chamber 3 ends haveflusher coupling 5;

The hollow body that describeddrainage tube 2 is made by medical grade silicon rubber, center aresluice way 6, andsluice way 6 front are to having one or more conduction holes 7.Describeddrainage tube 2 inwalls are provided with brace rod, and being radially, spiraldistributes.Sluice way 6 ends have a three-way valve 8, connect a pressure-measuring pipe and a drainage system respectively.

Described flushinghole 4,conduction hole 7 are circular hole, square hole or strip hole.Describedsyringe pipe 1,drainage tube 2 ends have length mark.

During use, routine is carried out the lumbar puncture art, and suitable lumbar puncture needle has: Touhg type inclined-plane, Cranford type inclined-plane; The Whitacrt plagiohedral, take out nook closing member after the thorn people subarachnoid space, cerebrospinal fluid flows out smoothly, andsyringe pipe 1 can be inserted, with the accurate position relation of judging most advanced and sophisticated with puncture pin hole and subarachnoid space, withdraw from lumbar puncture needle with reference tosyringe pipe 1 tip length labelling then.Drainage tube 2 is inserted in the passage in thesyringe pipes 1, enters subarachnoid space alongsyringe pipe 1 guiding, with reference todrainage tube 2 tip length labellings so that theconduction hole 7 ofdrainage tube 2 all be exposed to outside the syringe pipe 1.This moment, cerebrospinal fluid entereddrainage tube 2 byconduction hole 7, utilized the three-way valve 8 ofsluice way 6 ends, carried out pressure measurement or drainage procedure.Becausedrainage tube 2 inwalls are provided with radially spiral brace rod, also can not cause the pipeline pressurized so change position immediately, influence drainage effect.Flushing if desired then connects flushing device withflusher coupling 5, and as syringe or flushing pump, the flushing liquor malleation enterssyringe pipe 1interlayer chamber 3,interlayer chamber 3 is expanded opened, and discharges the effect that reaches flushing by flushing hole 4.Can wash simultaneously and drain.As not washing, then disconnectflusher coupling 5 or close flushing pump, this moment,interlayer chamber 3 pressure diminished, because it is medical silica-gel thatsyringe pipe 1 gets material, yielding, be subjected to the outer soft tissue compressing oftract interlayer chamber 3 closures, cerebrospinal fluid can adverse current not pollute flushing device.

Need to prove; particular of the present utility model is described in detail this utility model; for a person skilled in the art, in the various conspicuous change of under the situation that does not deviate from spirit and scope of the present utility model it being carried out all within protection domain of the present utility model.
