Abstract

The utility model discloses an anti-embedding type drainage tube, in particular to an anti-embedding type drainage tube, belonging to the technical field of manufacturing of medical equipment. The utility model provides the anti-embedding type drainage tube which can prevent tissues in an abdominal cavity from being transferred into a drainage hole in a use process after the anti-embedding type drainage tube is placed into the body of a patient. The anti-embedding type drainage tube comprises a hard drainage tube which is provided with the drainage hole in a tube wall and the outer side of the hard drainage tube is further sleeved with a layer of a soft drainage tube provided with a drainage hole; and a drainage gap is reserved between the hard drainage tube and the soft drainage tube; and the drainage hole in the hard drainage tube and the drainage hole in the soft drainage tube are mutually staggered.

Description

A kind of anti-embedding type drainage tube

Technical field

This utility model relates to a kind of drainage tube, especially relates to a kind of anti-embedding type drainage tube, belongs to manufacture technology field of medical appliance.

Background technology

The intraperitoneal drainage art is a technology commonly used in the department of general surgery operation, is used for Intraabdominal hydrops drain alleviating the human body untoward reaction to external thereby reach, and promotes the purpose of body recovery.The conventional at present intraperitoneal drainage device that in clinical position, uses is mainly the hard of all size and model or the blood plasma pipe of soft silica gel drainage tube and rubber material.This drainage system is because there is following problem in the problem of design or material:

(1) the easy embedding of intraperitoneal tissue causes difficulty in decannulation: on the current clinical widely used peritoneal cavity drainage tube several conduction holes are arranged, body is a single layer structure, and its outside does not have the outer anti-layer structure of prevention intraperitoneal tissue embedding conduction hole; Therefore, after drainage tube was inserted, the tissues such as intestinal wall of Intraabdominal omentum majus, epiploic appendices even edema were prone to " changing over to " conduction hole; And because the drainage tube material is really up to the mark or soft excessively; The tissue that embeds is prone to into be difficult for, and often causes difficulty in decannulation, when extracting by force; Bring misery to the patient, make troubles to clinical position.

(2) existing product material and drainage effect are not good enough: clinical existing drainage tube material is really up to the mark or soft excessively.The drainage tube quality of common silica gel material is hard partially, is difficult for bending in actual the use, and is prone to the friction abdominal visceral browser; And the blood plasma drainage tube quality of rubber material is soft partially, presses off easily, thereby causes inadequate drainage.

The utility model content

This utility model technical problem to be solved is: provide a kind of insert in the patient after, in use, can play preventing that intraperitoneal tissue from changing the interior anti-embedding type drainage tube of conduction hole over to.

The technical scheme that adopts for solving the problems of the technologies described above is: a kind of anti-embedding type drainage tube; Be included in tube wall and be provided with the hard drainage tube of conduction hole; Also be socketed with the soft drainage tube that one deck is provided with conduction hole in the outside of hard drainage tube; Have the drain gap between hard drainage tube and the soft drainage tube, and conduction hole and the conduction hole on the soft drainage tube on the hard drainage tube are staggered each other.

Further be, have support protrusion on the outer surface of hard drainage tube, the drain gap is confirmed through support protrusion.

The optimal way of such scheme is that support protrusion is the brace rod on the outer surface that longitudinally is arranged on the hard drainage tube.

Further be on the inner surface of hard drainage tube, also to be provided with described brace rod.

Further be that the drain gap is greater than 1.5mm.

Further be, the hard drainage tube is processed by silica gel material, and soft drainage tube is processed by elastomeric material.

Further be that hard drainage tube and soft drainage tube are one-body molded.

The beneficial effect of this utility model is: through at the outside of hard drainage tube socket one soft drainage tube; And the conduction hole that has between hard drainage tube and the soft drainage tube on a drain gap, the hard drainage tube and the conduction hole on the soft drainage tube are staggered each other; Like this; After the anti-embedding type drainage tube of said structure inserted patient's intraperitoneal, organize the hard drainage tube that further changes over to, can prevent effectively that just the intraperitoneal tissue from changing in the conduction hole owing to be lined with the intraperitoneal that can stop that conduction hole staggers in the inboard of soft drainage tube; Both made and changed over to; The amount that changes over to is also very little, can influence extracting of drainage tube hardly, thereby when extracting drainage tube, just can not bring new misery to sufferer.

Description of drawings

Fig. 1 is the structural representation of a kind of anti-embedding type drainage tube of this utility model;

Fig. 2 is the transverse sectional view of a kind of anti-embedding type drainage tube of this utility model.

Be labeled as among the figure: conduction hole 1, hard drainage tube 2, soft drainage tube 3, drain gap 4, support protrusion 5.

The specific embodiment

As Fig. 1, shown in Figure 2 be that this utility model provides a kind of insert in the patient after, in use, can play preventing that the intraperitoneal tissue from changing the anti-embedding type drainage tube in the conduction hole over to.Said anti-embedding type drainage tube is included in the hard drainage tube 2 that tube wall is provided with conduction hole 1; Also be socketed with the soft drainage tube that one deck is provided with conduction hole 1 in the outside of hard drainage tube 2; Have drain gap 4 between hard drainage tube 2 and the soft drainage tube 3, and the conduction hole (1) on conduction hole on the hard drainage tube 21 and the soft drainage tube (3) staggers each other.Like this; After the anti-embedding type drainage tube of said structure inserted patient's intraperitoneal, organize the hard drainage tube 2 that further changes over to, can prevent effectively that just the intraperitoneal tissue from changing in the conduction hole 1 owing to be lined with the intraperitoneal that can stop that conduction hole 1 staggers in the inboard of soft drainage tube 3; Both made and changed over to; The amount that changes over to is also very little, can influence extracting of drainage tube hardly, thereby when extracting drainage tube, just can not bring new misery to sufferer.

Because outside drainage tube is processed by soft material; In order to prevent that use is pressed on the hard drainage tube; The shutoff conduction hole causes can't drain, on the outer surface of hard drainage tube 2, has support protrusion 5, and drain gap 4 is confirmed through support protrusion 5; Further in order to make support effect better, support protrusion 5 is the brace rod on the outer surface that longitudinally is arranged on hard drainage tube 2.Although the material of inner hard drainage tube 2 is harder; But the situation that in use still often occurs being crushed and can't drain; For fear of this situation occurring; On the inner surface of hard drainage tube 2, also be provided with described brace rod, like this, both made the situation that occurs being crushed also can not cause the drain difficulty.In order to reduce the overall dimensions of this anti-embedding type drainage tube, can play good drainage again simultaneously, drain gap 4 is greater than 1.5mm.

For the ease of the manufacturing of the anti-embedding type drainage tube of this utility model, hard drainage tube 2 is one-body molded with soft drainage tube 3.
