Abstract
The utility model discloses an indwelling casing for lumbar puncture, which belongs to the field of medical accessories. The utility model is characterized in that the indwelling casing comprises a flushing tube and a drainage tube, wherein the flushing tube is a hollow hose made of medical silica gel, the tube body is provided with an interlayer chamber, the outer wall of the front end of the interlayer chamber is provided with one or more flushing holes, and the tail end of the interlayer chamber is provided with an external joint of a flusher. The hollow tube body of the drainage tube is a drainage channel, and the front end of the drainage channel is provided with one or more drainage holes in the side direction. Compared with the prior art, the indwelling casing is capable of simultaneously flushing and draining without influencing intracranial pressure and polluting the flushing channel.
Description
[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: comprise syringe pipe 1, drainage tube 2, wherein, the hollow hoses that described syringe pipe 1 is made for medical silica-gel, body is provided with interlayer chamber 3, interlayer chamber 3 front end outer walls are provided with one or more flushing holes 4, and interlayer chamber 3 ends have flusher coupling 5; Described drainage tube 2 hollow bodys are sluice way 6, and sluice way 6 front are to having one or more conduction holes 7.
Above-mentioned drainage tube 2 is made by medical grade silicon rubber.
Above-mentioned drainage tube 2 inwalls are provided with brace rod, and being radially, spiral distributes.
Above-mentioned sluice way 6 ends have a three-way valve 8, connect a pressure-measuring pipe and a drainage system respectively.。
Above-mentioned flushing hole 4, conduction hole 7 are circular hole, square hole or strip hole.
Above-mentioned syringe 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.
[description of drawings]
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 comprises syringe pipe 1, drainage tube 2.
Wherein, the hollow hoses that described syringe pipe 1 is made for medical silica-gel, body is provided with interlayer chamber 3, and interlayer chamber 3 front end outer walls are provided with one or more flushing holes 4, and interlayer chamber 3 ends have flusher coupling 5;
The hollow body that described drainage tube 2 is made by medical grade silicon rubber, center are sluice way 6, and sluice way 6 front are to having one or more conduction holes 7.Described drainage tube 2 inwalls are provided with brace rod, and being radially, spiral distributes.Sluice way 6 ends have a three-way valve 8, connect a pressure-measuring pipe and a drainage system respectively.
Described flushing hole 4, conduction hole 7 are circular hole, square hole or strip hole.Described syringe 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, and syringe 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 to syringe pipe 1 tip length labelling then.Drainage tube 2 is inserted in the passage in the syringe pipes 1, enters subarachnoid space along syringe pipe 1 guiding, with reference to drainage tube 2 tip length labellings so that the conduction hole 7 of drainage tube 2 all be exposed to outside the syringe pipe 1.This moment, cerebrospinal fluid entered drainage tube 2 by conduction hole 7, utilized the three-way valve 8 of sluice way 6 ends, carried out pressure measurement or drainage procedure.Because drainage 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 with flusher coupling 5, and as syringe or flushing pump, the flushing liquor malleation enters syringe pipe 1 interlayer 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 disconnect flusher coupling 5 or close flushing pump, this moment, interlayer chamber 3 pressure diminished, because it is medical silica-gel that syringe pipe 1 gets material, yielding, be subjected to the outer soft tissue compressing of tract 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.
