Abstract
A kind of locking alignment Double cavity pig tail conduit, comprise catheter body, joint and lock-in line, the front end of catheter body is pigtail-shaped, the front end of catheter body is cecum, catheter body comprises body and interlayer, and this interlayer extends along tube length direction body is separated into two-chamber, and middle section, two chambeies is circular is guidewire lumen, cross section be circular arc be feed liquor tube chamber, guidewire lumen in pigtail-shaped bending sidewall on be provided with some hole for back flow, a wire hole and an entrance hole; Lock-in line penetrates guidewire lumen from joint A, after wire hole passes, penetrate guidewire lumen again by entrance hole, is finally passed by joint A.This utility model locking alignment Double cavity pig tail conduit arranges double cavity structure, and after conduit implant into body, extracted out by seal wire, flushing liquor arrives focus through feed liquor tube chamber, and the liquid that need excrete flows out external through guidewire lumen; By tensioning with loosen lock-in line, regulate the amount of crimp of pigtail catheter front end, prevent pigtail catheter generation dystopy.
Description
Technical field
This utility model relates to technical field of medical instruments, particularly relates to a kind of locking alignment Double cavity pig tail conduit.
Background technology
Pigtail catheter, because of butt curl, end is similar to pigtail and gains the name, and pigtail catheter achieves and applies widely in urological kidney, ureter, operation on bladder.Use patient's management after surgery of drain in pigtail catheter to be tending towards simplifying, because conduit is built-in, patient can early ambulant, and decrease infection chance, nursing work load obviously reduces, and patient's post-operative recovery is fast, and the hospital stays obviously shortens.But clinically, the pigtail catheter in some patient body there occurs dystopy, causes it ineffective, taking-up of need performing the operation time serious, causes huge actual bodily harm and extra-pay expenditure to patient.
Utility model content
The purpose of this utility model is to solve the problem, and provides a kind of locking alignment Double cavity pig tail conduit.
The technical solution of the utility model is:
A kind of locking alignment Double cavity pig tail conduit, comprise catheter body and joint, body is connected with joint, the front end of catheter body is pigtail-shaped, it is characterized in that: also comprise lock-in line, the front end of described catheter body is cecum, catheter body comprises body and interlayer, body is separated into two-chamber along the extension of tube length direction by this interlayer, middle section, two chambeies is circular is guidewire lumen, cross section be circular arc be feed liquor tube chamber, guidewire lumen is provided with some hole for back flow on the sidewall of the bending in pigtail-shaped, a wire hole and an entrance hole, when the catheter body of pigtail-shaped is cut-off state, hole for back flow is positioned at the front end of entrance hole, wire hole is positioned at the front end of hole for back flow, described feed liquor tube chamber is provided with some liquid outlets on the sidewall of the bending in pigtail-shaped, described joint comprises the joint A be connected with guidewire lumen and the joint B be connected with feed liquor tube chamber, described lock-in line penetrates guidewire lumen from joint A, after wire hole passes, penetrate guidewire lumen again by entrance hole, is finally passed by joint A.
As preferably, the sectional area of guidewire lumen is greater than the sectional area of feed liquor tube chamber.
As preferably, the aperture of liquid outlet is less than the aperture of described hole for back flow.
As preferably, the end of lock-in line is provided with fixing clamper.
As preferably, catheter body is cylindric body.
As preferably, catheter body is polyurethane material.
The beneficial effects of the utility model are:
This utility model locking alignment Double cavity pig tail conduit arranges double cavity structure, after conduit implant into body, seal wire is extracted out, medicine or flushing liquor are through feed liquor tube chamber, focus is arrived from liquid outlet, the liquid that need excrete flows into guidewire lumen from hole for back flow, and flow out external through guidewire lumen, a poling can realize the object of administration and flushing;
By tensioning with loosen lock-in line, regulate the amount of crimp of pigtail catheter front end, prevent pigtail catheter generation dystopy, avoid the painful and monetary loss of the operation that causes to patient because of pigtail catheter generation dystopy.
