Abstract

The utility model relates to an interventional catheter for interventional therapy, in particular to an interventional therapy catheter, which belongs to the technical field of structures of medical instruments and comprises a catheter body (4). One end of the catheter body (4) is connected with a handle (3), and the end of the catheter body (4) is inserted inside the handle (3). The interventional therapy catheter is characterized in that a branch tube (2) which is communicated with the catheter body (4) and used for injecting radiography fluid is arranged on the handle (3). The interventional therapy catheter is reasonable and simple in structural design and convenient and labor-saving in use. The radiography fluid can be injected into blood vessels directly by the aid of the branch tube of the interventional therapy catheter, and whether the depth of the catheter inserted into the blood vessels is proper or not can be observed without drawing out a guide wire in the catheter, so that safety in operation is enhanced, suffering of patients is relieved, and time is saved for medical staff.

Description

A kind of interventional therapy conduit

Technical field

This utility model relates to employed interposing catheter in a kind of interventional therapy, belongs to technical field of medical appliance structures.

Background technology

Interventional therapy is little with its safety, wound, short treating period, painful few several big advantage are widely used in clinical treatment, when carrying out vascular interventional treatment, will use interposing catheter usually, and interposing catheter generally cooperates its inner seal wire to use together in use; Conduit inserts to want to observe behind the blood vessel and gets into that the degree of depth is whether suitable then need release the seal wire in the conduit; And then receive the syringe that contrast solution is housed on the conduit, through syringe contrast solution is injected in the blood vessel and observe, in this process; Seal wire is easy to cause local hemorrhage after extracting out; And conduit also is easy to come off, and safety is not high, and trouble operates; Strengthened patient's slight illness, wasted time and energy.

Summary of the invention

The purpose of this utility model is to solve the weak point that above-mentioned prior art exists, provide a kind of use safe ready, time saving and energy saving, needn't extract the interventional therapy conduit that seal wire can directly be observed out.

This utility model is realized through following technical scheme:

A kind of interventional therapy conduit; Comprise catheter body 4; One end of catheter body 4 is connected with pipe handle 3, and an end of catheter body 4 is sheathed on the inside of pipe handle 3, and special character is to offer on the said pipe handle 34 that communicate with catheter body, as to be used to inject a contrast solution arm 2;

The end of said arm 2 is provided with the haemostatic valve 1 that is used to prevent the blood backflow.

A kind of interventional therapy conduit of this utility model; Reasonable in design is simple and direct, and it is laborsaving to be easy to use, and can directly through arm contrast solution be injected in the blood vessel; Whether unnecessary extract the seal wire in the conduit out can need the observation conduit intravasation degree of depth suitable; Increased the safety of operation, alleviated slight illness, saved the time to medical personnel to the patient.

Description of drawings

Fig. 1: be a kind of interventional therapy guide-tube structure of this utility model sketch map.

The specific embodiment

Following with reference to accompanying drawing, provide the specific embodiment of this utility model, be used for the formation of this utility model is further specified.

Embodiment 1

A kind of interventional therapy conduit of present embodiment is with reference to figure 1; Comprise catheter body 4; One end of catheter body 4 is connected with pipe handle 3, and an end of catheter body 4 is sheathed on the inside of pipe handle 3, offers 4 that communicate with catheter body, as to be used to inject a contrast solution arm 2 on the said pipe handle 3; The end of said arm 2 is provided with the haemostatic valve 1 that is used to prevent the blood backflow.

A kind of interventional therapy conduit of present embodiment; Reasonable in design is simple and direct, and it is laborsaving to be easy to use, and can directly through arm contrast solution be injected in the blood vessel; Whether unnecessary extract the seal wire in the conduit out can need the observation conduit intravasation degree of depth suitable; Increased the safety of operation, alleviated slight illness, saved the time to medical personnel to the patient.

Claims

1. interventional therapy conduit; Comprise catheter body (4); One end of catheter body (4) is connected with pipe handle (3); One end of catheter body (4) be sheathed on the pipe handle (3) inside, it is characterized in that offering on the said pipe handle (3) one with catheter body (4) arm that communicate, that be used to inject contrast solution (2).

2. according to the said a kind of interventional therapy conduit of claim 1, it is characterized in that the end of said arm (2) is provided with the haemostatic valve (1) that is used to prevent the blood backflow.
