Description
Technical field
The present invention relates to medical drainage equipment technical field more particularly to a kind of drainage devices in adjustable drain region.
Background technique
On clinical medicine, after performing the operation to patient, to prevent postoperative infection, promote postoperative wound healing,
It usually needs to be adapted to drain age-tube device, it can lead to purulence, blood and the liquid etc. in tissue or in body cavity in vitro.
Drain age-tube device is applied to the postoperative of multiple location, including thoracic cavity, encephalocoele, gastrointestinal tract, biliary tract etc..
The drainage tube of the prior art is mostly the tubular structure of cylinder, offers conduction hole on its excircle, is being used
When it is inserted into the patient, to drainage tube be connected to negative pressure, so that the purulence, blood and liquid etc. in body cavity are drawn to body by conduction hole
Outside.
However the prior art is in use, those skilled in the art at least have found following technical problem:
1) drainage tube of the prior art is columned, and adsorption range is limited after entering body cavity, so as to cause drainage effect
Fruit is bad；
2) drainage tube of the prior art is only capable of draining purulence, blood and the liquid near at body cavity, for a long time to same
One region, which carries out negative pressure drainage, to cause to damage to the internal organs at this.
Therefore, it is necessary to a kind of completely new adjustable drainage device in drainage region be provided, to solve the above problems.
Summary of the invention
It, can be to drawing in order to solve the above technical problems, the present invention provides a kind of drainage device in adjustable drain region
Stream region is adjusted, so that negative pressure drainage will not be carried out to a region for a long time, and adsorption range is big, drainage effect
It is good.
A kind of drainage device in adjustable drain region provided by the invention, including outer tube 100, outside outer tube 100
There are several conduction holes 101, the conduction hole 101 is gradually subtracted by quantity on outer tube 100 upper end to the direction of lower end on circumference
It is few, there is the port passed through for inner sleeve structure 200 in 100 upper end of outer tube, when in use, people is inserted into 100 upper end of outer tube
