Abstract

The utility model relates to a medical drainage tube, aiming at providing a medical drainage tube with seldom broken drainage holes, good effect in drainage and long duration of service. The detailed proposal of the utility model is that the connecting base(3) is arranged; the anterior part of the connecting base is connected with the drainage tube(1) with the elastic materials while the posterior part is connected with an extension tube(5); a tube clip(4) is arranged on the extension tube; a joint(6) is arranged at the back end of the extension tube; a drainage hole(2) is arranged at the anterior part of the drainage tube(2). The utility model is characterized in that the anterior part of the drainage tube presents in an arcus circular inclined backwards in the natural state without external force.

Description

The medical drainage conduit

Technical field

This utility model belongs to a kind of medical drainage conduit that is used for clinical treatment.

Background technology

Referring to Fig. 1, the medical drainage conduit primary structure of Shi Yonging is clinically: elastoplast drainage tube (1) rear end is connected with Connection Block (3), the Connection Block rear portion is connected to extension pipe (5), the extension pipe is provided with vessel clamp (4), the rear end is provided with joint (6), drainage tube (1) front end is provided with conduction hole (2), its using method is: earlier steel wire is inserted from joint (6), pass extension pipe (5) successively, Connection Block (3), drainage tube (1), directly reach the drainage tube front end, utilize the strength of steel wire that drainage tube is inserted human body soft tissue then, extract steel wire again out, with vessel clamp conduit and human body relative fixed, the joint of extension pipe rear end is connected with syringe, can extract the pus in the soft tissue out drain, usually drainage catheter need be embedded in for a long time and carry out drain in the human lesion tissue, the weak point of existing medical drainage conduit is: the drainage tube front portion is straight tube, after inserting human body, its front end outside wall surface contacts with human body soft tissue fully, conduction hole is easy to be blocked, and promptly will more not renew pipe for a long time so use.

Summary of the invention

The technical problems to be solved in the utility model provides a kind of conduction hole and is difficult for stopping up, and drainage effect is good, the medical drainage conduit that service time is long.

The technical scheme that addresses the above problem is (referring to implementing illustration): this utility model is provided with Connection Block (3), its front portion is connected with the drainage tube (1) of elastic material, the rear portion is connected to extension pipe (5), the extension pipe is provided with vessel clamp (4), extension pipe rear end is provided with joint (6), drainage tube (1) front portion is provided with conduction hole (2), it is characterized in that: described drainage tube (1) front end is recurvate circular-arc under the naturalness that is not subjected to external force.

With this utility model drain the time, the joint (6) of steel wire from the rear end inserted, and reach the drainage tube front end, the drainage tube elasticity support of bending is straight, earlier go out some steel wires after inserting the human lesion position to pumpback, send one section drainage tube more forward, send while taking out so repeatedly, promptly that the drainage tube front portion is bent in soft tissue is circular-arc for the elastic recovering force of effect by steel wire and drainage tube, and make soft tissue in crooked circular arc, form a cavity (7), then steel wire is all extracted out, with drainage tube and human body relative fixed, the pus in the soft tissue can be seeped into and enter drainage tube from conduction hole in the cavity and drain with vessel clamp.

After this utility model drainage tube front end inserts human body, can make soft tissue in the crooked circular arc of drainage tube front end, form cavity, thereby the drain that helps pus in the soft tissue is discharged, drainage effect is good, and conduction hole is difficult for stopping up, can prolong the service time of drainage catheter, can be extended to half a year the service time that this utility model inserts human body by original two months.

Specific embodiments

This routine drainage catheter 1 usefulness elastic soft plastic is made, and its front end is

Shape, the rear end is connected with Connection Block 3, and Connection Block 3 rear portions are connected to extension pipe 5, and extension pipe rear end is a cone joint 6, is used for being connected with syringe, and vessel clamp 4 is housed on the extension pipe, is used for and the human body relative fixed.

Described conduction hole 2 is arranged on the interior curved wall of drainage tube 1 front end, is more conducive to infiltrate the pus discharge of cavity 7 like this.

Claims (2)

1, medical drainage conduit, be provided with Connection Block (3), its front portion is connected with the drainage tube (1) of elastic material, the rear portion is connected to extension pipe (5), the extension pipe is provided with vessel clamp (4), extension pipe rear end is provided with joint (6), and drainage tube (1) front portion is provided with conduction hole (2), it is characterized in that: described drainage tube (1) front end is recurvate circular-arc under the naturalness that is not subjected to external force.

2, medical drainage conduit according to claim 1 is characterized in that: described conduction hole (2) is arranged on the interior curved wall of drainage tube (1) front end.
