The drain tube can be a closed type, and also can be an opened type. The inside of the streamline shape head part of the closed type drain tube is provided with the positioning groove of the guide steel needle. The utility model adopts the silicon rubber hose which has appropriate hardness, good issue compatibility, small damage to the brain tissue and nerve fiber and clear CT imaging, since the scale and the back figure line are arranged on the tube wall in the axis direction, clinical observation is facilitated. The utility model has the advantages of simple structure, reasonable end design, convenient operation and accurate orientation and positioning, can largely reduce the damage to the brain tissue and the nerve fiber, has high safety, and is suitable to be manufactured into non-toxic and aseptic and disposable intracranial hematoma drain instrument.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically a kind of intracranial hematoma drainage tube.
Background technology
As everyone knows, along with the transformation of society to aging, hypertensive cerebral hemorrhage has become a kind of commonly encountered diseases frequently-occurring disease, and this disease has the three-hypers characteristics of high incidence, high mortality, high disability rate.The occupy-place effect of intracranial hemorrhage and the cerebral edema of following cause that functional neurosurgery suffers oppression, intracranial pressure raises patient's cognitive disorder, quadriplegia, degree of depth stupor, threat to life at any time.Must intracranial hemorrhage be controlled and it is drained in time by surgical operation clinically, reduce intracranial pressure simultaneously, relief of symptoms, stablize the vital sign index, with redemption life.Wicresoft's intracranial hematoma drainage extensive use clinically at present, people have designed many drainage systems for this reason, as the patent No. is the cranium brain external drainage conduit of ZL2006200843982, it comprises drainage tube, guiding draw point, drainage tube is a silica gel hose, front end is provided with several side openings, and head is the semicircle ball-type of sealing.Drainage tube semicircle ball-type inner portion is provided with guiding draw point head detent.Several side openings that its front end is provided with are easily stopped up by blood clot, cause inadequate drainage, and the drainage tube head is the dome-type of sealing, resistance is bigger during the cranium built-in pipe, damage to cerebral tissue and nerve fiber is bigger, and after drainage tube was inserted intracranial in addition, the directivity of side opening was difficult to judge and control.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of structure reasonable, simple in structure, easy for operation, accurate positioning, and drain is unobstructed, and thorough, small, the safe intracranial hematoma drainage tube of wound purify the blood.
The technical scheme in the invention for solving the above technical problem is: a kind of intracranial hematoma drainage tube, comprise drainage tube, guiding draw point, it is characterized in that: drainage tube is sleeved on guiding draw point outside, and its leading section is provided with the folded side opening of two mistakes, and outer wall is provided with graduated scale and figure viewed from behind line.
The scale division value of the said graduated scale of this utility model is 1cm.
This utility model said drainage tube side opening center and graduated scale figure viewed from behind line are on same straight line.
The said drainage tube front end of this utility model can be for closed, and the termination is the bullet-shaped streamlined, and the streamlined inner portion is provided with guiding draw point detent.Said drainage tube front end also can be open type, and promptly the front end tube head is provided with opening.
This utility model drainage tube adopts medical grade silicon rubber special hose material, and hardness is suitable, and histocompatibility is good, and is little to cerebral tissue and nerve fiber damage, and it is clear to develop at CT; Tube wall is axially arranged with scale and figure viewed from behind line, is convenient to clinical observation; The guiding draw point cooperates guiding, orientation, location with drainage tube, the mid-pipe of art position is accurate, reliable, and wound is little; Two wrong folded side opening in the 10mm scope, lateral aperture is to being 2～3mm, drain is unobstructed in the art, drain is thorough.This utility model is simple in structure, and termination accurate positioning reasonable in design, easy to operate, directed has greatly reduced the damage to cerebral tissue and nerve fiber, and is safe, is suitable for making nontoxic aseptic disposable intracranial hematoma drainage apparatus.

The specific embodiment
From Fig. 1, Fig. 2, Fig. 3, Fig. 4 as can be seen, a kind of intracranial hematoma drainage tube comprises drainage tube 1, guiding draw point 2, and said drainage tube 1 is sleeved on guiding draw point 2 outsides, its leading section is provided with the folded side opening 3 of two mistakes, and the drainage tube outer wall is provided with graduated scale 5 and figure viewed from behind line 6.Drainage tube 1 is the medical grade silicon rubber flexible pipe, and medical grade silicon rubber flexible pipe hardness is suitable, and histocompatibility is good.Guiding draw point 2 is the medical stainless steel goods, and guiding draw point 2 inserts in the drainage tube 1, cooperates guiding, orientation, location with drainage tube 1, and the mid-pipe of art position is accurate.Drainage tube 1 runs through into haematoma cavity between cerebral tissue and blood vessel, and is little to cerebral tissue and nerve fiber damage, and it is clear to develop at CT; Tube wall is axially arranged with graduated scale and figure viewed from behind line, is convenient to clinical observation.
The scale division value of the said graduated scale of this utility model is 1cm.This utility model said drainage tube side opening 3 centers and graduated scale figure viewed from behind line 6 are on same straight line.Like this, may command drainage tube 1 is inserted the intracranial degree of depth, and according to drain situation in the art, adjusts the direction of side opening 3, to realize the drain of different azimuth.This utility model drainage tube 1 tube wall is provided with two wrong folded side openings 3, and side opening 3 radial dimensions reach 2-3mm, and drain is unobstructed in the art, drain is thorough.After the intracranial hematoma drainage tube imports the intracranial success, extract guiding draw point 2, drainage tube 1 is connected with other devices, the row drainage.
Fig. 1, Fig. 2 are a kind of closed intracranial hematoma drainage tubes, and said drainage tube front end is closed, and the termination is the bullet-shaped streamlined, and the streamlined inner portion is provided with guiding draw point detent 4.The center, termination and detent 4 centers of guiding draw point 2 match, and avoid relative displacement.
Fig. 3, Fig. 4 are open type intracranial hematoma drainage tube structural representations.Said drainage tube 1 front end also can be open type, and promptly the front end tube head is provided with opening 7.The front end of guiding draw point 2 and the opening of drainage tube 1 coincide, and are streamlined, and the resistance in the time of can reducing the cranium built-in pipe reduces the damage to cerebral tissue and nerve fiber.
This utility model is simple in structure, and termination accurate positioning reasonable in design, easy to operate, directed has greatly reduced the damage to cerebral tissue and nerve fiber, and is safe, is suitable for making nontoxic aseptic disposable intracranial hematoma drainage apparatus.
