Abstract

The utility model relates to an adaptation associated drainage catheter, including elastic heliciform body, the pipe wall of body is equipped with the memory metal layer. It has the pjncture needle of being used for male inner chamber to open in the body. The utility model discloses well memory metal layer receives human influence of temperature in the human body, can deform into to keep the structure unchangeable after the spiral of the human inner space of adaptation to fine seek connections with the displacement that prevents the body between each viscera tissue, support that the body formed naturally in say in the chamber tension can be fine on the wall is said in the chamber and do not damage the tissue, the body pass through the chamber say arc striking portion helical shape body can be outside the way of chamber formation than the chamber bigger cross -section of way, the body can't be deviate from under the natural circumstances. The influence of memory metal layer human body outside temperature variation and tensile become straight is carried out abluent the time when taking out associated drainage catheter to thereby it is convenient for rinse the body to flare -out the heliciform. The utility model discloses specially adapted abdominal cavity, thorax postoperative drainage and the first newborn postoperative drainage.

Description

Self adaptation deformation drainage catheter

Technical field

This utility model relates to the drainage system of clinic, in particular to a kind of self adaptation deformation drainage catheter.

Background technology

Now with the development of medical science, the application of all kinds of drainage technologies is very general, also occurs in that number of types of drainage catheter simultaneously, but the conduits that great majority use at present substantially with straight type, little stumble ring-like for representative

Drain itself be body secretes residual material it can be the secretions of pathological changes or Postoperative Residual, indwelling time can cause the tissue around drain to infect after for a long time in vivo, serious danger pole life, so using drainage tube drain to become the maximally effective method preventing from infecting. Such as, the drainage method commonly used at present is sebific duct to be placed on pathological changes and Post operation needs the position of drain, and the other end does otch and passes from stomach wall, draws intraperitoneal hydrops.

But currently used drainage tube has following drawback mostly: general straight type drainage tube does not have fixing point in human body, and therefore when human motion, conduit is susceptible to displacement, not only affects the effect of drain, is also easy to cause the damage to in-vivo tissue; It is fixing that little ring-like conduit of stumbling also is only limited to after by tract to carry out, and is substantially free of fixation in large space in abdominal cavity and bigger tract.

Summary of the invention

This utility model aims to overcome that above-mentioned the deficiencies in the prior art provide a kind of self adaptation drainage catheter, and this drainage catheter simple in construction has good extensibility, it is possible to be well supported on and do not damage tissue on tract wall, and is easy to rinse.

Realizing this utility model purpose and the technical scheme is that a kind of self adaptation drainage catheter, including elastic helicoids, the tube wall of described body is provided with memory metal layer.

In technique scheme, in described body, have the inner chamber inserted for puncture needle.

In technique scheme, the front end of described body is additionally provided with conduction hole.

The tube wall of this utility model drainage catheter is provided with memory metal layer, this memory metal layer is subject to the impact of human body temperature in human body, deformation can be produced, it is subject to the impact of internal each viscera tissue, can shape become adapt to people's intracorporeal space spiral type after keep structure constant, thus well seeking connections with the displacement preventing body between each viscera tissue, tension force at tract interior tube body self-assembling formation can well be supported on and not damage tissue on tract wall, when body is by tract drain, spiral body can form the cross section bigger than tract outside tract, cannot deviate from natural situation lower tube body.

In time taking out drainage catheter and be carried out, memory metal layer stretches straighten in the impact of the outer variations in temperature of human body, thus helical form being stretched consequently facilitating clean body.

This utility model is particularly well-suited to abdominal cavity, thoracic cavity postoperative drainage and first breast postoperative drainage.

Accompanying drawing explanation

Fig. 1 is the structural representation of this utility model spiral type Multi-cavity multifunction drainage catheter.

Fig. 2 be this utility model spiral type Multi-cavity multifunction drainage catheter inner chamber in insert puncture after schematic diagram.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

As it is shown in figure 1, this utility model spiral type Multi-cavity multifunction drainage catheter, including body 1, body 1 is for having elastic helicoidal structure, and the tube wall of body 1 is provided with memory metal layer 2, has inner chamber 3 in body 1, and body 1 front end is additionally provided with conduction hole 4.

When using this utility model, body 1 is outer linear at human body, is injected from inner chamber 3 by puncture needle, then from external be punctured to internal, after completing, puncture needle is taken out from inner chamber 3, now, memory metal layer 2 is in human body, by the impact of human body temperature, deform upon, under impact between human body viscera tissue, it is possible to keep structure constant after forming the helical structure adapting to people's intracorporeal space, as shown in Figure 2.

In time taking out body 1 and be carried out, memory metal layer is stretched become linearity again by the impact of outdoor temperature outside human body, consequently facilitating clean.
