Abstract
The utility model discloses an ultra-smooth moisture-retention indwelling drainage catheter with an ultra-smooth coating and the two branches. The indwelling drainage catheter comprises a catheter body, and is characterized in that an opening and a side hole are formed in the front end of the catheter body, the two branches are connected to the rear end of the catheter body through a connecting base, one branch serves as a catheterization and drainage channel, and the other branch serves as a flushing and sampling channel. By means of the indwelling drainage catheter, the difficulty of catheterization can be lowered, tissue injury can be reduced, the success rate of operations can be increased, the risks of secondary catheterization and complications can be reduced, and liquid medicine flushing, sampling assays and the like can be carried out under the condition that drainage is not interrupted. The indwelling drainage catheter is wide in clinical application range.
Description
Technical field
This utility model relates to drainage catheter technical field, relates to more specifically a kind of drainage from indwelling conduit with branch.
Background technology
Drainage catheter is for hydrops, the pneumatosis drain of the human intracavity such as in thoracic cavity, abdominal cavity, pelvic cavity or internal organs, the drainage tube of part small dimension adopts Sai Erding puncture method to insert body, first use hollow lancet puncture skin and subcutaneous tissue, then guide wire is sent to lesion via hollow puncture needle, extract puncture needle, with convergent divergent channel, to skin and subcutaneous tissue reaming, then drainage catheter is sent into lesion along guide wire, carry out drain.But easily give a discount to cause in putting the process of pipe because catheter tube is partially soft, put tube failure, need secondary Pin pipe, and conduit only has a tract, rushing liquid and drain can not operate simultaneously, and clinical manipulation is very inconvenient.
Utility model content
The purpose of this utility model is exactly the drainage from indwelling conduit with branch a kind of simple in structure, easy to use providing in order to solve the deficiency of prior art.
This utility model is to adopt following technical solution to realize above-mentioned purpose: a kind of drainage from indwelling conduit with branch, comprise conduit, it is characterized in that, described catheter proximal end is provided with opening and side opening, rear end of conduit connects at least Liang Ge branch by catheter block, wherein at least one branches into the passage of putting pipe and drain, and at least one branching into rushed liquid and sampling channel.
As further illustrating of such scheme, described conduit is coated with medical superslide coating, and medical superslide coating is by then drying and be prepared from hydrophilic polymer co-extrusion or with the solution coating conduit of hydrophilic polymer.
Described catheter proximal end is provided with 4～10 side openings.
The front end of described conduit is set to linear type or flexure type.
Described side opening along straight line or with spiral distribution in catheter proximal end side.
The beneficial effect that this utility model adopts above-mentioned technical solution to reach is:
1, this utility model adopts conduit with superslide coating, and contact liq rear tube surface is very lubricated, can lower the difficulty of putting pipe, reduces tissue injury, improves the success rate of operation, reduces the risk of secondary Pin pipe and complication.
2, conduit is provided with 4～10 side openings with front end, guarantees that drain is smooth and easy.
3, rear end of conduit, with two individual branches, can, in the situation that not interrupting drain, carry out the operations such as medicine liquid washing and sampling chemical examination.
4, conduit can be kept somewhere in vivo, and indwelling time is the longest 30 days, can reduce the frequency of replace tubes.

The specific embodiment
Below in conjunction with specific embodiment, specific embodiments of the present utility model is described in further detail.Embodiment 1
As shown in Figure 1, a kind of drainage from indwelling conduit with branch of this utility model, comprises conduit 1, conduit 1 front end is provided with opening and side opening 2, conduit 1 rear end connects Liang Ge branch by catheter block 3, and one of them branches into puts pipe and drainage channel 4, and another branches into and rushes liquid and sampling channel 5.Conduit 1 is coated with medical superslide coating, and medical superslide coating is by then drying and be prepared from hydrophilic polymer co-extrusion or with the solution coating conduit of hydrophilic polymer.Conduit 1 front hole number is 4～10.The front end of conduit 1 is set to linear type, and side opening is distributed in catheter proximal end side along linearity.
Embodiment 2
As shown in Figure 2, the difference of the present embodiment and above-mentioned embodiment is, the front end of described conduit 1 is set to flexure type, and side opening 2 is distributed in catheter proximal end side along linearity.
Embodiment 3
As shown in Figure 3, the difference of the present embodiment and above-mentioned embodiment is, the front end of described conduit 1 is set to linear type, and side opening 2 is along spiral distribution in catheter proximal end side.
Embodiment 4
As shown in Figure 4, the difference of the present embodiment and above-mentioned embodiment is, the front end of described conduit 1 is set to flexure type, and side opening is along spiral distribution in catheter proximal end side.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, do not departing under the prerequisite of this utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
