When using, penetrate the seal wire in the body, the seal wire makes the body be in rectilinear state, and the seal wire is when penetrating the end that curls, owing to curl the end and set up the elasticity strip, consequently the seal wire required power can the grow when stretching into the end that curls, sets up the gyro wheel at the seal wire end, and the gyro wheel can avoid the seal wire to sting bad body.

Description

Single J pipe external member

The technical field is as follows:

the utility model relates to a single J pipe external member.

Background art:

the two ends of the pigtail catheter are bent under the natural condition to avoid the dislocation of the pigtail catheter, a winding sleeve or a spring is arranged in the catheter in order to further avoid the dislocation of the catheter by the prior manufacturer, the winding sleeve or the spring can increase the bending strength of the catheter to avoid the dislocation, when in use,

penetrate the seal wire in the pigtail pipe, the seal wire makes the pigtail pipe be in rectilinear state, and the seal wire is when penetrating the curling end of pigtail pipe, owing to set up wire winding cover or spring in curling the end, consequently the seal wire required power can the grow when stretching into curling end, and the seal wire can stab bad pigtail pipe, influences the result of use.

The invention content is as follows:

the utility model provides a single J pipe external member for solving the problem that above-mentioned prior art exists.

The utility model discloses the technical scheme who adopts has:

a single J catheter kit comprising: the drainage tube comprises a tube body, wherein one end of the tube body is a blind end, the other end of the tube body is an open end, the blind end of the tube body is of a curled structure, an installation groove is formed in the curled inner circumferential wall of the blind end of the tube body, an elastic strip which is bent into a curled shape is arranged in the installation groove, the outer side face of the elastic strip is lower than the outer side face of the tube body, and a plurality of drainage holes are formed in the curled outer circumferential wall of the blind end of the tube body;

the seal wire, the seal wire adopts alloy steel to make, is equipped with the gyro wheel at the end of seal wire, and the gyro wheel adopts medical silica gel material.

Further, the elastic strip is fixed in the mounting groove through glue.

Further, the elastic strip is made of nickel-titanium alloy with memory property.

Furthermore, a pull ring is arranged on the guide wire.

Furthermore, the tail end of the guide wire is provided with a mounting hole, and the roller is mounted in the mounting hole through a bolt.

The utility model discloses following beneficial effect has:

when using, penetrate the seal wire in the body, the seal wire makes the body be in rectilinear state, and the seal wire is when penetrating the end that curls, owing to curl the end and set up the elasticity strip, consequently the seal wire required power can the grow when stretching into the end that curls, sets up the gyro wheel at the seal wire end, and the gyro wheel can avoid the seal wire to sting bad body.

The utility model discloses low cost, especially to disposable pigtail pipe, when retrieving in the later stage, the elasticity strip is taken out easily and is left, with elasticity strip sterilization treatment back, can be utilized once more, it is with low costs.

Description of the drawings:

fig. 1 is a structural diagram of the present invention.

Fig. 2 is a cross-sectional view of the elastic strip in the tube body according to the present invention.

Fig. 3 is a structural diagram of the elastic strip of the present invention.

The specific implementation mode is as follows:

the present invention will be further described with reference to the accompanying drawings.

Referring to fig. 1 to 3, the present invention relates to a single J catheter set, which includes a catheter body 1 and a guide wire 3.

One end of the pipe body 1 is a blind end, the other end of the pipe body is an open end, the blind end of the pipe body is of a curled structure, an installation groove 11 is arranged on the inner curled circumferential wall of the blind end of the pipe body 1, and an elastic strip 2 which is bent into a curled shape is arranged in the installation groove 11. The outer side surface of the elastic strip 2 is lower than the outer side surface of the tube body 1, so that the elastic strip 2 is prevented from leaking out of the tube body 1, the smoothness of the outer wall surface of the tube body 1 is ensured, and the pain of a patient during puncture is reduced. A plurality of drainage holes are arranged on the curled outer circumferential wall of the blind end of the tube body 1.

The guide wire 3 is made of alloy steel, so that the strength is high and the guide wire is not easy to deform. The tail end of the guide wire 3 is provided with a roller 31, and the roller 31 is made of medical silica gel materials.

A pull ring 32 is provided on the guide wire 3, and the pull ring 32 facilitates pulling the guide wire.

To facilitate the installation of the roller, a mounting hole is provided at the end of the guide wire 3, and the roller 31 is installed in the mounting hole by a bolt.

The utility model provides an in elastic strip 2 is fixed in mounting groove 11 through glue, guarantee the fastening effect, avoid elastic strip 2 to break away from body 1.

The elastic strip 2 in the utility model is made of nickel-titanium alloy with memory performance.

When using, penetrate seal wire 3 in body 1, seal wire 3 makes body 1 be in rectilinear state, and seal wire 3 is when penetrating the end that curls, owing to curl the end and set up elastic strip 2, consequently seal wire 3 can the grow when stretching into the end that curls required power, sets up gyro wheel 31 at 3 ends of seal wire, and gyro wheel 31 can avoid 3 stabs bad bodies 1 of seal wire.

After the guide wire is pulled out, the blind end of the tube body 1 can be automatically curled to form a spiral structure. The elastic strip 2 on the tube body 1 can ensure the curling and returning, avoid the pigtail catheter from generating dislocation and reduce the risk.

The utility model discloses low cost, especially to disposable pigtail pipe, when retrieving in the later stage, elastic strip 2 is taken out easily and is left, with elastic strip 2 sterilization process after, can be utilized once more, with low costs.
