Description
Technical field
The utility model belongs to medical instruments field, in particular to a kind of anti-extrusion drainage tube.
Background technique
For the purulence gathered between tissue or in body cavity, blood, liquid to be directed in vitro, drainage catheter need to be used to carry out outer
Section's drainage.Medical drainage tube is mostly silastic material at present, has round tube, flat tube, cross pipe etc. from cross-sectional shapes point, because of circle
The reasons such as type drainage tube is easy vascular compression and nerve, but lumen is big, and drainage is fast, clinically often by round tube and other two kinds of shapes
The drainage catheter of shape is used in combination.
Though being referred to a kind of novel surgical drainage catheter in patent 201120178530.7, which is circle
Pipe, one end are cross pipe, and the round tube and cross pipe one-pass molding are integrated, though the cross cross branch of tube portion reason
It supportting, drainage effect is preferable, and small to patient's bring pain when extraction, but cylindrical parts are supported because of without internal, once it is crowded
Pressure will cause the blocking of entire tube body, bring inconvenience to clinical use, but will lead to if supporter is added round tube and
The connection of other instruments becomes problem, and certain pain is brought to patient, therefore how to solve the above problems as this field
Problem.
Summary of the invention
The utility model in view of the deficiencies of the prior art, provides a kind of anti-extrusion drainage tube, which is outer
The uniform integrally formed drainage tube of pipe size, wherein drainage tube one end is the cross pipe with outer groove, and the other end is round tube, ten
It is semi-buried that font pipe and round tube intersection are that the gradual change round tube and outer groove that interior section is cross are faded in intersection, and reaches
Become inside groove before round tube completely, one to be connected with intersection section round tube inner wall is equipped with multiple protrusions, the utility model structure letter
Single, reasonable, easy for operation, cross pipe and the design of round tube internal projection play the role of inner support, and drainage is avoided to block,
Drainage efficiency is high.
The specific technical solution of the utility model is:
A kind of anti-extrusion drainage tube, the drainage tube are size of outer tube uniformly integrally formed drainage tube, wherein drainage tube
One end is the cross pipe with outer groove, and the other end is round tube, cross pipe and the gradual change that round tube intersection is that interior section is cross
Round tube, and outer groove fades to semi-buried in intersection, and becomes inside groove completely before reaching round tube, one to be connected with intersection section
Round tube inner wall is equipped with multiple protrusions, and the height of projection becomes smaller along drainage direction until disappearing；
Using the drainage tube of this structure, because using integral forming process, round tube and cross pipe intersection shape
Smoothly, entire outer tube diameter is of uniform size, and compared with the drainage tube of bonding, tensile strength is big, and tube body will not occur for use process
The case where fracture, and because one section of round tube and the inner wall of cross pipe close part are equipped with multiple protrusions, and the height of projection
Become smaller along drainage direction until disappearance, can thus play the role of inner support, both remain the good spy of round tube drainage effect
Point, and will not be crushed, drainage is preferably played, another section of round tube is interior without protrusion, is easily installed guidance needle or connection is drawn
Stream container, the design of cross tube portion multiple-grooved can block entire drainage tube to avoid clot, it is ensured that the entire pipeline of drainage tube it is smooth
Logical, outer groove fades to semi-buried in intersection, and becomes inside groove completely before reaching round tube, in this way can be by drainage-fluid from drainage
It is introduced in pipe outside pipe, avoids the generation for the problems such as notch caused by directly changing blocks；
Further round tube internal projection is the radial and consistent strip projected parts of cross tube seat, and number is 4；
In addition to this, developing line is additionally provided on tube body, developing line setting is where the cross support of any bar and protrusion
On radial inboard wall of tube body, when use, determines insertion position and the depth of drainage tube by developing line；Entire drainage tube is using medical
Silica gel is made, good biocompatibility, no sensitivity response, material safety.
In conclusion using the drainage tube of this structure, simple and reasonable for structure, easy for operation, cross pipe and circle
The design of pipe internal projection plays the role of inner support, and drainage is avoided to block, and drainage efficiency is high.

Specific embodiment
A kind of anti-extrusion drainage tube, the drainage tube are size of outer tube uniformly integrally formed drainage tube, wherein drainage tube
One end is the cross pipe 1 with drainage outer groove, and the other end is round tube 2, and it is ten that cross pipe 1, which is interior section with 2 intersection 3 of round tube,
The gradual change round tube of word, and drain outer groove 4 and faded in intersection semi-buried, and become inside groove completely before reaching round tube, with friendship
One section of round tube inner wall being connected at remittance is equipped with multiple raised 6, and 6 height of protrusion becomes smaller along drainage direction until disappearing；
2 internal projection 6 of round tube is the radial and consistent strip projected parts of cross tube seat, and number is 4；
Developing line 5 is additionally provided on the tube body of cross pipe 1 and round tube 2, developing line 5 is arranged in the cross support of any bar
On inboard wall of tube body radial where protrusion.
