The head end of the seal wire 3 is connected to the tail end of the seal wire brush 2；The seal wire brush 2 includes seal wire body of the brush 2-1 and is connected to institute
Multiple bristle 2-2 of seal wire body of the brush 2-1 are stated, the bristle 2-2 helically divides along the length direction of the seal wire body of the brush 2-1
Cloth.The tail end of the seal wire body of the brush 2-1 and the head end of the seal wire can be integrally formed.The bristle can be Flexible brush
Hair.The seal wire and the seal wire brush can be integrally formed, and the dredging conduit and the seal wire, seal wire brush can be respectively only
Vertical component.
As shown in Fig. 2, the dredging conduit 1 may include sequentially connected duct entry end 1-1, catheter main body 1-2 and
Conduit outlet end 1-3；According to close to the direction of the catheter main body 1-2, the caliber of the duct entry end 1-1 can successively subtract
Small, according to close to the direction of the catheter main body 1-2, the caliber of the conduit outlet end 1-3 can be gradually increased.The dredging
Conduit 1 is penetrated from 3 tail end of seal wire, and the diameter of the seal wire 3 is equal with the sealing bore of 4 central hole 5 of rubber stopper, the seal wire
3 head end is connected to the tail end of the seal wire brush 2.
As shown in Fig. 2, the catheter main body 1-2 can offer the side opening 1- for filling the water or extracting nasointestinal tube tamper
4, the side opening 1-4, which can be in fluid communication, side pipe 1-5, and the side opening 1-4 can be opened in the side of the catheter main body 1-2
And it can be arranged close to the position of the duct entry end 1-1.Seal wire brush is by after tamper is cleared up in nasointestinal tube, Huo Zheke
Nasointestinal tube is washed away with being filled the water by side pipe into catheter main body, or air extractor can be connected at side pipe will to clear up
Tamper afterwards is released.
As shown in figure 3, the seal wire body of the brush 2-1 and the seal wire 3 can be cylindric, the seal wire body of the brush 2-
1 diameter can be less than the diameter of the seal wire 3, and the diameter of the seal wire 3 can be less than the conduit outlet end 1-3 caliber most
Caliber at small position.
As shown in Fig. 2, the caliber at the conduit outlet end 1-3 caliber maximum position can be less than 1.5mm.
A kind of embodiment, 3 leading portion tip of seal wire are designed using round blunt, effectively nasointestinal tube are avoided to be pierced, effectively avoided
Peritoneal free cancer cells.
As shown in figures 1 to 6, the length of the seal wire 3 can be 170-180mm, and the length of the dredging conduit 1 can be
The length of 150-160mm, the seal wire body of the brush 2-1 can be 5-10mm；The duct entry end 1-1 can be filled with sealing
Rubber stopper 4 can offer perforation 5 among the sealing rubber stopper 4, and the internal diameter of the perforation 5 and the outer diameter of the seal wire 3 can
With equal.
As shown in figure 3, the diameter of the length of the bristle 2-2 and the seal wire body of the brush 2-1 can satisfy such as following formula 1：
1.6mm≤single bristle lengths * 2+ seal wire body of the brush diameter≤2mm formula 1.
When in use, exposed parts can be straightened, first enters nasointestinal tube with seal wire brush, remove the attached of nasointestinal tube tube wall
Object such as meets obstructions, and shows to block, and writing down the distance apart from intestinal tube entrance at this time is that (dredging conduit and seal wire surface can be with by L1
Indicate scale), 10mm firmly slightly is pushed ahead, distance at this time is L2, it is pumped repeatedly between L1 and L2 and rotates seal wire brush,
Until resistance sense disappears, along seal wire root merging conduit to L1, duct entry is closed, passes through side opening pumpback nose with 20mL needle tubing
The liquid and content of intestinal tube, then salt water 5mL is injected, seal wire brush pushes forward again, when such as meeting obstructions, repeats above-mentioned movement
Until entering the head of nasointestinal tube.It needs to guarantee when using the nasointestinal tube cleaning plant to have moisture in nasointestinal tube and conduit,
And then it can guarantee lubricity；Exposed portion (nasointestinal tube) can be constantly in straight condition, reduce camber, and then can reduce resistance
Power；The position of conduit can be kept constant, motionless, not outer de- when pumping seal wire, amplitude is no more than 20mm, and seal wire and conduit cannot
It retreats simultaneously, in order to avoid resistance increases and increases nasointestinal tube abjection risk, should first move back conduit, then move back seal wire；In bolus salt water
Before, it first confirms that inject resistance little, nasal tube is avoided to burst.In addition, following item needs to pay attention to：1, it operates doctor or nurse answers
There is the early warning of height to realize, when washing pipe feels to have i.e. starting plugging when resistance to handle prediction scheme, has a resistance and not complete in flushing pipe
It is the best opportunity of unclog the pipe when full blocking.2, x ray photograph must be carried out before dredging, excludes the feelings that internal nasointestinal tube gives a discount
Condition.3, when seal wire is dredged, avoid violence dredging；Enteron aisle is damaged to prevent wearing out conduit.4, seal wire and conduit enter depth and cannot surpass
Cross the length of nasointestinal tube.
The tube wall of the dredging conduit 1 and the surface of the seal wire 3 can be coated with hydrophilic coating layer.By dredging
The hydrophilic coating layer that the outer surface coating of the inside and outside tube wall, seal wire of conduit is described can be effectively reduced coefficient of friction, improve profit
Slip is more quick and laborsaving when carrying out the cleaning of nasointestinal tube tamper.
The bristle 2-2 and the seal wire body of the brush 2-1 can be integrally formed.
Although above having used general explanation and specific embodiment, the present invention is described in detail,
On the basis of the present invention, it can be made some modifications or improvements, this will be apparent to those skilled in the art.Cause
This, these modifications or improvements, fall within the scope of the claimed invention without departing from theon the basis of the spirit of the present invention.
