Background technology
Acute and chronic subdural hematoma is the very common disease of neurosurgery, must carry out holing, placing drainage, could remove hematoma to the compressing of cerebral tissue, treatment patient.Conventional surgical drainage process is: cut scalp, sphenotresia, cuts dura mater, placing drainage to subdural hematoma chamber, the from the beginning subcutaneous extraction connect drainage bag of the other end of drainage tube.Existing drainage tube is one direction straight peen, after drainage tube is placed on Subdural space, can only facing one direction, often because of other direction hematoma drain not thoroughly the movable drainage tube of needs to change direction drain again.Even if shortcoming changes direction drain to be also difficult to make all directions hematoma thoroughly flow out, change chance and infection chance that direction increases brain injury, and drainage tube is easily deviate from from boring.Also there is no a kind of drainage system of applicable subdural hematoma at present.
Utility model content
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, provides a kind of drainage system for subdural hematoma, and this drainage system stationarity being used for subdural hematoma is good, in multiple directions drain, avoids producing dead angle.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is, a kind of drainage system for subdural hematoma, comprise drainage tube and connection tube, drainage tube is connected by joint with one end of connection tube, and two tubes inside is communicated, the other end of drainage tube is provided with multiple bifurcated, and multiple bifurcated is arranged around the axis of drainage tube, multiple bifurcated constitutes for being placed on Subdural space, and play the drainage head of drain and fixation, on drainage head, cover has for the control piece making it draw in and to decontrol, the other end of connection tube is connected with drainage bag.
Further, the plurality of bifurcated close-packed arrays circularizes or is spaced and circularizes.
Further, the plurality of bifurcated forms by by the other end longitudinal shear of drainage tube.
Further, this control piece is the pipe that two ends communicate.
Further, the flap of this bifurcated to be front end be arc.
Further, this bifurcated is arch.
Further, the inwall of this each bifurcated also offers the groove for drain, groove along bifurcated length direction and arrange.
Further, the number of this bifurcated is 3 ~ 6.
Further, the one end near joint on this connection tube is also provided with three-way valve.
Further, this connection tube is also provided with flow rate regulating valve, and is also connected with surge flask between control valve and drainage bag.
A kind of drainage system for subdural hematoma of this utility model, tool has the following advantages: 1. one end of drainage tube is provided with multiple bifurcated, so just on multi-direction, be provided with drainage channel, in the process of drain, ensure that the hydrops of all directions or blood by drain, can not leave dead angle; And need not movable drainage head repeatedly.2. the flap of bifurcated to be front end be arc, one is that stickiness is good, and arcuate front ends can not patient harm.3., when bifurcated is arch, contact surface is large, is convenient to drain.4. drainage head is also provided with the pipe making it draw in, facilitates putting into of drainage head, particular/special requirement is not had to sphenotresia, misery and the burden of patient can not be increased.5. each bifurcated is after Subdural space opens, and serves the effect of buckle simultaneously, ensure that drainage head can not skid off in drainage process.6. the diapire of each bifurcated also offers groove, ensure that gathering and flowing to of in drainage process hydrops, and drain is more thorough.

Detailed description of the invention
Embodiment 1
As depicted in figs. 1 and 2, a kind of drainage system for subdural hematoma, comprise drainage tube 3 and connection tube 6, drainage tube 3 is connected by joint 4 with one end of connection tube 6, and two tubes inside is communicated, the other end of drainage tube 3 is provided with 6 bifurcated 2-1, and 6 bifurcated 2-1 arrange around the axis of drainage tube 3,6 bifurcateds constitute for being placed on Subdural space and the drainage head 2 of a drain and fixation, on drainage head 2, cover has the control piece 1 for making it draw in, the pipe that control piece 1 communicates for two ends.Facilitate drainage head 2 to insert in sphenotresia, when drainage head 2 inserts after in boring, then bifurcated 2-1 is scattered, this arrangement ensure that drainage head 2 integrally enters, to the size of sphenotresia without particular/special requirement, misery and the burden of patient can not be increased.The other end of connection tube 6 is connected with drainage bag 9.One end near joint 4 on connection tube 6 is also provided with three-way valve 5, connection tube 6 is also provided with flow rate regulating valve 7, is also connected with surge flask 8 between control valve 7 and drainage bag 9, reduce the probability infected in drainage process.6 bifurcated 2-1 close-packed arrays circularize.Bifurcated 2-1 forms by by the other end longitudinal shear of drainage tube 3.The flap of bifurcated 2-1 to be front end be arc, stickiness is good, and front end is arc, can not damage patient.The inwall of each bifurcated 2-1 also offers the groove 2-2 for drain, groove 2-2 along bifurcated 2-1 length direction and arrange.Groove 2-2 is the runner as drain hematoma, and under the effect of intracranial external pressure difference, hematoma is drained along groove 2-2, can not produce blocking, avoid adjusting device, improve drainage efficiency.
A kind of drainage system for subdural hematoma of this utility model, during use, inserts in sphenotresia by drainage head 2 together with control piece 1, enters after in boring, pull back pipe, and after pipe is pulled away from drainage head 2, bifurcated 2-1 opens, and completes the process of insertion.Under the effect of intracranial external pressure difference, hematoma is drained, and according to the situation of patient, adjustment control valve 7 carrys out coutroi velocity.Be provided with multiple bifurcated 2-1, the hydrops of Subdural space all directions can be made to be sucked, avoid producing dead angle, and need not repeatedly move drainage head 2 in the process of drain, also reduce the probability of infection.Meanwhile, each bifurcated 2-1 also serves the effect of buckle, can not skid off in the process of drain, ensure that the safety in drainage process.
Embodiment 2
As shown in figures 1 and 3, a kind of drainage system for subdural hematoma of this utility model, is with the difference of embodiment 1, bifurcated 2-1 is 3, and is spaced and circularizes, and bifurcated 2-1 is arch.Contact surface is large, is convenient to drain.
A kind of drainage system for subdural hematoma of this utility model, when bifurcated 2-1 is flap, each bifurcated 2-1 also can be spaced and circularize; When bifurcated 2-1 is arch, each bifurcated 2-1 also can closely circularize by arranged adjacent.
