Abstract

The present invention is one kind of vascular intubation blockage device, and belongs to the field of medical operation equipment technology. Structurally, the vascular intubation blockage device includes one bent metal rod, spring ring, handle, ring with small hooks in two ends and elastic band. The vascular intubation blockage device is made of elastic stainless steel wire and has the blocking end capable of being pressed to open. After completing the intubation insertion, the blockage device is implanted to complete the blocking through releasing fingers. Experiment shows that the present invention has satisfactory blocking effect.

Description

Vascular intubation blockage device

One, technical field

The present invention relates to a kind of vascular intubation blockage device, belong to medical instruments field, is the medical surgery weapon exercises.

Two, background technology

During cardiac operation, set up extracorporeal circulation row superior and inferior vena cava intubated and drained in the past, be blocking blood flow, and all will bring and finish with blocking-up.So just need to wear blocking-up band (it also is like this that peripheral vessels is set up extracorporeal circulation), like this, increased operating procedure on the one hand, prolonged operating time at the free circumvascular tissue in the position of blocking-up blood vessel; Damage surrounding tissue on the other hand, also may cause the severe complication of secondary injured blood vessel.

Three, summary of the invention

The technical problem that the present invention solves is: do not need free blood vessel and wear the blocking-up band, can finish the vascular catheterization blocking-up, reduced operating procedure, saved operating time, avoid occurring secondary damage.

Technical solution:

The present invention includes one single metallic rod, this single top is out of shape conglobate turn, turn continues two branches that and bends to the tetragonal handle of the crossing formation of certain angle, handle intersects the back and forms the annular circle, annular circle two ends bend to little shackle, the common block side that forms block device is with rubber band between two little shackles.

Continue two branch's symmetric curvature that and become an angle of 90 degrees.

Single metallic rod is rustless steel and rubber-like steel wire.

Annular circle two ends are closed under naturalness.

The present invention does not need free blood vessel and wears the blocking-up band by experiment, can finish the vascular catheterization blocking-up, and barrier effect is satisfied.As a result, omitted operating procedure and time, reduced the operation technique difficulty, reduced stimulation heart.The severe complication that secondary injured blood vessel can not occur.

Four, description of drawings

Fig. 1 is a structural representation of the present invention;

Five, the specific embodiment

The present invention includes a metallic rod 1 that bends to single, single metallic rod 1 material is rustless steel and rubber-like steel wire.This single is to be out of shape conglobate elastic ring 2 by a top, two branches of continuity form handle 3 mutually with it, have the cross section of a width on two component zones of handle 3 greater than its bar, be beneficial to and pinch press operation, two branches bend to crossing tetragonal shank and the annular circle 4 of crossing back formation of forming of an angle of 90 degrees, and 4 liang of ends of annular circle bend to little shackle 5, the common block side that forms block device is with rubber band 5 of two shackles.

This apparatus structure is simple, and is easy to operate.Handle 3 is deformed into two branches by the elastic ring 2 and the described elastic ring 2 at top, and the block side is opened, and two branches of handle 3 pinch has the cross section of a width greater than its bar on the splenium subregion; Round ringwise 4 (can be made into different model, to satisfy the requirement of different blood vessel thickness) in block side, terminal little shackle 5 is closed under naturalness, is with rubber band on two shackles 5.In operation, set up extracorporeal circulation, after vascular catheterization is finished, when needing blocking-up, will be ready to insert the vascular intubation blockage device of rubber band, pinch with finger and press handle that it is opened, insert, unclamp finger, can finish from the position of needs blocking-up.

Claims

1, vascular intubation blockage device, it is characterized in that: it comprises one single metallic rod (1), this single top is out of shape conglobate turn (2), turn (2) continues two branches that and bends to the crossing tetragonal handle (3) that forms of certain angle, handle (3) intersects the back and forms annular circle (4), annular circle (4) two ends bend to little shackle (5), form the block side of block device jointly, are with rubber band between two little shackles (5).

2, vascular intubation blockage device according to claim 1 is characterized in that: continue two branch's symmetric curvature that and become an angle of 90 degrees.
