Abstract

A novel interventional catheter mainly comprises a catheter body (1) and a catheter handle (4). A branch catheter (3) is arranged on the catheter handle (4), a hemostasis valve (2) is disposed on the branch catheter (3), the tail end of the branch catheter (3) is in the shape of a hopper (5), the branch catheter (3) is communicated with the catheter body (1), and an inner cavity of the tail end of the catheter handle (4) is in the shape of the hopper (5), so that a guide wire can be inserted into the inner cavity of the tail end of the catheter handle (4) conveniently. During usage, when an operator needs to observe whether the depth of the novel interventional catheter entering a blood vessel of a patient is proper or not or needs to testify whether the catheter enters a predetermined target blood vessel, the guide wire does not need to be drawn out, and contrast liquid can be directly filled via the branch catheter by the aid of a syringe.

Description

Novel interposing catheter

Technical field

This utility model relates to a kind of novel interposing catheter, is used for the work of medical science interventional therapy.

Background technology

Interventional therapy is emerging medical field, and interposing catheter is the apparatus that is mainly used in the blood vessel intervention diagnosis and therapy.When carrying out the blood vessel intervention diagnosis and therapy; At first carry out the Seldinger vascular puncture; Insert conduit in the blood vessel then; Be inserted into seal wire the conduit from the catheter tip opening more as required, through the operation that cooperatively interacts of conduit and seal wire, with conduit be inserted to check in the target vessel that will get into and treat.When getting involved intubate after conduit is inserted into a certain vessel segment; If whether the degree of depth of observation conduit intravasation is suitable; In the time of will confirming maybe whether conduit gets into predetermined target vessel; Just need seal wire be extracted out from conduit, and then be connected in conduit handle end openings portion, in blood vessel, inject contrast agent through conduit again and observe with syringe.Like this, not only time-consuming, and also conduit is also deviate from from the vessel branch that has inserted easily after seal wire is extracted out, and operation can affect the terminal syringe that is connected of conduit handle for conduit in addition, uses very inconvenient.

The utility model content

In order to overcome the deficiency in the background technology, this utility model provides a kind of novel interposing catheter, and this novel interposing catheter has solved the problem that the repeatable operation seal wire is extracted out from conduit.

This utility model solves the technical scheme that its technical problem adopted: a kind of novel interposing catheter; Mainly by body, the pipe handle is formed, and on the pipe handle, is provided with branched pipe; On branched pipe, be provided with haemostatic valve; The end of branched pipe is funnel-form, and branched pipe communicates with body, and the terminal inner chamber of pipe handle is funnel-form.

This utility model is used for the work of medical science interventional therapy, reasonable in design, and novelty is skillfully constructed; It is little to take up room, and low cost of manufacture is increased work efficiency; And be easy to large-scale promotion application; Easy and simple to handle, need seal wire not extracted out from conduit and get final product the interposing catheter of liquid such as injection contrast agent and heparin saline in blood vessel.

Description of drawings:

Accompanying drawing 1 is the structural representation of novel interposing catheter.

Among the figure: the 1-body; The 2-haemostatic valve; The 3-branched pipe; 4-manages handle; The 5-funnel-form.

The specific embodiment:

With reference to accompanying drawing, a kind of novel interposing catheter is mainly by body 1; Pipe handle 4 is formed, and on pipe handle 4, is provided with branched pipe 3, on branched pipe 3, is provided with haemostatic valve 2; The end of branched pipe 3 is funnel-form 5, and branched pipe 3 communicates with body 1, and the terminal inner chamber of pipe handle 4 is funnel-form 5; So that the insertion seal wire, during use, when whether the needs observation conduit intravasation degree of depth appropriately perhaps will confirm whether conduit gets into predetermined target vessel; Need not extract seal wire out, directly from branched pipe, inject and get final product with the syringe holder contrast solution.

Claims

1. novel interposing catheter; Mainly by body (1), pipe handle (4) is formed, and it is characterized in that: on pipe handle (4), be provided with branched pipe (3); On branched pipe (3), be provided with haemostatic valve (2); The end of branched pipe (3) is funnel-form (5), and branched pipe (3) communicates with body (1), and the terminal inner chamber of pipe handle (4) is funnel (5).
