Abstract

The utility model relates to a vessel intubation blocking-up device, which belongs to a medical apparatus field, in particular to a medical operation apparatus sort. The utility model is characterized in structure in that the utility model comprises a metal rod curved to be a single element comprising a spring coil the top of which is circular and a handle formed by two ramifications continued to the spring coil, the two ramifications are curved to a certain angle to intersect to form the tetragonal handle portion and form an annular circle after intersection, two ends of the annular circle are curved to hamula circles for jointly forming the blocking-up end of the blocking-up device, and a rubber band is sleeved between the two hamula circles. The utility model is made of stainless steel wire materials with the elasticity, and within the elastic limit the blocking-up end is opened by pinch pressure. When the blocking-up is needed after the completion of vessel intubation during the operation, the blocking-up device is imbedded from the location where the blocking-up is needed, then the fingers are loosed for completion. The blocking-up effect is satisfactory through experiments.

Description

Vascular intubation blockage device

One, technical field

This utility model relates to a kind of vascular intubation blockage device, belongs 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 this utility model 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:

It comprises a metallic rod that bends to single, this single is to be the turn of circle by a top, two branches of continuity form handle mutually with it, two branches bend to certain angle and intersect the tetragonal shank of formation, back formation annular is round with intersecting, annular circle two ends bend to little shackle, form the block side of block device jointly, are with rubber band between two shackles.

Single top is circular.

Two branches bend to an angle of 90 degrees.

Have the cross section of a width on two component zones of handle greater than its bar.

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

Annular circle two ends are closed under naturalness.

This utility model 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 this utility model structural representation;

Five, the specific embodiment

This utility model comprises a metallic rod 1 that bends to single, and 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
