Description

A kind of sustainable perfusion and drainage pipe

Technical field

The utility model relates to the field of medical instrument technology, especially provide a kind of sustainable perfusion and drainage pipe.

Background technique

Now in society, the unsound life style of people, many reasons such as increase and shortage movement of life stress, Hypertensive cerebral hemorrhage is caused to have become a kind of common disease and frequently-occurring disease.The disease has high incidence, high mortality, high disability rate Three Gao Tedian.And hypertensive cerebral hemorrhage, position about 80% of intracranialing hemorrhage occurs in basal ganglia region, and basal ganglia region is The region that important nerve center Conductive fiber passes through, therefore, hypertensive cerebral hemorrhage often result in patient's not extremely i.e. residual situation, institute To be had very important significance using effective treatment that reasonable medical instrument carries out hypertensive cerebral hemorrhage.

Previous clinic mostly used operation of opening cranium mode to be treated hypertensive cerebral hemorrhage disease, this mode by In needing out cranium, in operation while removing intracerebral hematoma, the damage for causing brain tissue that can be different degrees of.In recent years, face It mostly uses Minimally Invasive Surgery mode to be treated on bed, i.e., carries out intracranial puncture and drainage using cranium brain drainage tube, this method is not Only promptly intracerebral hematoma can be drained to come, the additional injuries to brain tissue will not be caused, and fast with patient's recovery, Expense is low, patient's brain function is easy the advantages such as recovery, and therefore, this method is widely used.

With the development of modus operandi and surgical drainage instrument, single tube single-chamber drainage tube has been difficult to meet sufferer to drainage The demand of effect.Occur the drainage tubes such as single-tube multiple-cavity and the how sub- pipe of single tube immediately, if any drainage tube pass through in general pipeline Multiple sub- pipes are set, and by allowing sub- pipe to stretch out or be retracted into general pipeline in the sub- pipe telescopic hole of the front general pipeline setting, when , it can be achieved that multiple spot administration drains when general pipeline is stretched out in sub- pipe front, to accelerate dissolution and the drainage speed of blood clot, and then quickly Compressing of the hemotoncus for principal functional structure is released, reduces and is endangered caused by hypertensive cerebral hemorrhage disease.

But this drainage tube is due to the multiple sub- pipes being administered with multiple spot, it will certainly in the comparable situation of outer diameter Drainage lumens diameter is sacrificed, causes to drain rate decline, promotes plugging risk.Meanwhile injection of medicine need with hemotoncus have it is certain In the reaction time, drug, which does not react sufficiently with blood clot also, just draws from draining hole, influences the dissolution and drainage rate of blood clot, more Secondary artificial administration can bring infection risk again.

Utility model content

The utility model aim is to provide a kind of sustainable perfusion and drainage pipe, it is intended to solve drainage tube in the prior art and draw Stream chamber is small, the low technical problem of drainage rate.

A kind of in order to achieve the above purposes, the technical solution adopted by the utility model is: medical drainage tube, including tube body and The rear intubation of the tube body rear end is connected to and be located at the tube body, is had along its length in the tube body mutually isolated Drainage lumens and filling cavity are intubated after described and include the first branched pipe being connected to the drainage lumens and be connected to the filling cavity Second branched pipe, the front end of the tube body is equipped with multiple liquid outlets being connected to the filling cavity, on the side wall of the tube body It is additionally provided with the draining hole being connected to the drainage lumens, there is spacing between the draining hole and multiple liquid outlets.

Further, the draining hole and the spacing between nearest liquid outlet are 15mm-20mm.

Further, multiple first liquid outlets are distributed in divergent shape；Multiple second liquid outlets are along the tube body The distribution of length direction multiple spot, and be uniformly distributed circumferentially.

Further, multiple first liquid outlets are distributed in divergent shape；Multiple second liquid outlets are along the front end Side wall is uniformly distributed.

Further, first branch tube end is additionally provided with the female Luer for connecting outer conduit.

Further, the second branched pipe end is additionally provided with calparine cap.

Further, the draining hole at least two, at least two draining holes are between the tube length direction Every setting.

It further, further include and with the drainage lumens and the filling cavity parallel balloon cavity interior set on the tube body, The front end of the tube body is additionally provided with the positioning sacculus being connected to the balloon cavity for injecting liquid, it is described after intubation further include with The third branched pipe of the balloon cavity connection, the third branched pipe are equipped with check valve.

Further, it is additionally provided with transparent pilot balloon on the third branched pipe, the pilot balloon and described Position sacculus connection.

Further, first branched pipe, the second branched pipe and the third branched pipe are connected by pipe fitting In one.

The utility model has the beneficial effects that

In the utility model, compared to the prior art in the how sub- pipe of single tube drainage tube, be arranged in tube body mutually every From drainage lumens and filling cavity, realize that drainage and perfusion are independent, can have bigger drainage lumens under conditions of equivalent diameter, mention Height drainage rate, reduce plugging risk, and in the comparable situation in drainage lumens cross section than existing drainage tube have it is smaller Diameter can mitigate the extruding to brain tissue, reduce wound；It is realized in tube body front end by the multiple liquid outlets being connected to filling cavity Multiple spot administration, increase drug and hemotoncus contact area, high-efficiency dissolution hemotoncus, meanwhile, it is persistently irrigated and is compared by filling cavity Once daily increases the time of contact of drug and hemotoncus, and significantly more efficient dissolution hemotoncus is conducive to outside lead body；Meanwhile away from From draining hole is arranged at one fixed spacing of liquid outlet, so that drug is sufficiently reacted with hemotoncus, it is conducive to play drug effect, improves dissolution speed Rate shortens drainage tube indwelling time, reduces and punctures infection risk, also has positive effect to prognosis.
