Form of tubes, described second drainage tube 102 and resistance to press strip 103 be located at described first drainage tube 101 internal it is preferred that described first
Drainage tube 101 is flat, and for example its section can be rectangle, oval or cydariform ring, described second drainage tube 102
Cross section is preferably annulus, the longitudinal axis weight of the longitudinal axis of described second drainage tube 102 and described first drainage tube 101
Close.When the cross section of described first drainage tube 101 is rectangular shape ring, chamfering is carried out to four seamed edges of the first drainage tube 101,
Form round and smooth arc-shaped transition fillet, it is to avoid when drainage tube and human contact, human body is damaged.Described second drainage tube 102
Diameter slightly smaller than or be equal to the width of the first drainage tube 101.Described resistance to press strip 103 is divided into two parts, is located at second respectively
The both sides of drainage tube 102, the cross section of described resistance to press strip 103 can be triangle, rectangle or other shapes.First drain
Interfix between pipe 101, the second drainage tube 102 and resistance to press strip 103.The inner chamber of described second drainage tube 102 constitutes second and draws
Stream chamber 105, the cavity between described resistance to press strip 103 and the inwall of the first drainage tube 101 constitutes the first drainage lumens 104.In this reality
Apply in example, the length of described first drainage tube 101 is identical with the length of the main paragraph 1022 of the second drainage tube 102, resistance to press strip 103
Length identical with main paragraph 1022 length of the second drainage tube 102, the inserting paragraph 1011 of described first drainage tube 101 and main body
Section 1012 is all fixed together with described second drainage tube 102, resistance to press strip 103, and the inserting paragraph 1021 of the second drainage tube 102 is exposed
Described first drainage tube 101.It is evenly distributed multiple side openings 1013 in inserting paragraph 1011 both sides of the first drainage tube 101, in institute
The both sides stating the inserting paragraph 1021 of the second drainage tube 102 are evenly distributed multiple side openings 1023.
In a more preferred embodiment, described first drainage tube is about 20cm, wide 1cm, and thick 0.4cm is described resistance to
The section of press strip 103 is triangle, this triangular base width 0.15cm, high 0.3cm.Second drainage tube 102 external diameter is 0.3cm,
Long 25cm.Second drainage tube 102 stretches out the first drainage tube 101 about 5cm, and this extension is configured to described second drainage tube 102
Inserting paragraph 1021.The diameter of each side opening 1013,1023 is 0.15cm, and side opening spacing is 1cm.
Embodiment two:
As Figure 4-Figure 6, described first drainage tube 101 and the second drainage tube 102 are pipe or square tube (in figure illustrate
Situation for pipe), the first drainage tube 101 and the second drainage tube 102 separated by a distance placed side by side, described resistance to press strip 103
Positioned between described first drainage tube 101 and the second drainage tube 102, the cross section of the first drainage tube 101 and the second drainage tube 102
Equivalently-sized, the first drainage tube 101 and the second drainage tube 102 are arranged symmetrically with respect to resistance to press strip 103.When the first drainage tube 101
When being square tube with the second drainage tube 102, it is located at two seamed edges in outside and changes into arc-shaped, it is to avoid drainage tube and human contact
When human body is damaged.In this embodiment, the length of resistance to press strip 103 and the first drainage tube 101 and the second drainage tube 102
The length of main paragraph 1012,1022 is substantially the same, the main paragraph of resistance to press strip 103 and the first drainage tube 101, the second drainage tube 102
1012nd, 1022 it is fixed together, the inserting paragraph 1011,1021 of the first drainage tube 101 and the second drainage tube 102 continues to extend forward
Go out certain distance, be uniform-distribution with the inserting paragraph 1011 of the first drainage tube 101 and the second drainage tube 102,1021 both sides multiple
Side opening 1013,1023.
When the present invention drainage tube in neurosurgery to epidural, die under carry out drain when, after intracranial hematoma clearance,
The inserting paragraph of the first drainage tube is put into exterior dura gap, cerebral dura mater repairing, the inserting paragraph of the second drainage tube is put into hard brain
Gap under film, at the general 1.5cm of operative incision, is about the otch of 1.2cm, draws simultaneously through the subcutaneous far-end by drainage tube
Fixing, two drainage tube far-ends connect drainage bag respectively, thus the bleeding to two gaps under epidural, die carries out drain simultaneously.
The drainage tube of the present invention is due to being provided with two drainage lumens simultaneously, and is provided with pressure between two drainage lumens
Bar, is not only able to gap under epidural, die to be carried out drainage tube in drain, and drainage process simultaneously and local will not be occurred curved
Folding, drainage process is unobstructed smoothly, and simple to operate, greatly reduces the probability that patient occurs intracranial infection.
It should be noted that in this application, such as first and second or the like relational terms are used merely to one
Entity or operation are made a distinction with another entity or operation, and not necessarily require or imply between these entities or operation
There is any this actual relation or order.
It is last that it is noted that obvious, above-described embodiment is only intended to clearly illustrate example of the present invention, and simultaneously
The non-restriction to embodiment.For those of ordinary skill in the field, can also do on the basis of the above description
Go out change or the variation of other multi-forms.There is no need to be exhaustive to all of embodiment.And thus drawn
Obvious change that Shen goes out or change among still in protection scope of the present invention.
