The objective of the invention is following realization: designed a kind of external guided cardiac catheterization equipment, it includes: injecting propeller, multi-joint three-way device and thick conduit.In the diameter range that cardiac catheter use to allow, the thick conduit cavity of design is separated into not connected and thin cavity that be evenly distributed more than two or two to tubular intracavity by difform barrier film.All thin cavity in the thick conduit is in the top closure of thick conduit.In suitable distance below the top of thick conduit, on the thin cavity outer wall of each root, be provided with a spout.This spout only communicates with the thin cavity at its place.The effect of spout is the spray reaction forces of utilizing from the normal saline of spout ejaculation, and the cardiac catheter head is moved direction.So just can be under perspective, control the different directions of the thin cavity spout of each root spray reaction forces, thereby the traffic direction of the cardiac catheter head in external control intracorporeal heart makes the cardiac catheter head turn traffic direction at the cardiac valve place, waltz through the valve narrow orifice, and reach in the predetermined chamber.At the afterbody of quite long thick conduit, all tail catheter by the end of each thin cavity is drawn interlocks mutually with the joint of corresponding combination hub with the corresponding band valve of multi-joint three-way device respectively.Another the total head that connects three-way device is connected with the injection port of injecting propeller again more.
When being inserted under perspective by vein, this conduit moves to the cardiac valve place, in the time of need passing this valve, with the valve open on that joint of the multi-joint three-way device that tail catheter interlocked of the thin cavity of certain root, by the injecting propeller that is connected with multi-joint three-way device, an amount of normal saline is injected in the thin cavity, and then from the spout of this thin cavity, the saline recoil strength that ejects moves a upper/lower positions to the cardiac catheter head.At this moment under perspective, control the injection recoil strength of other thin cavity, thereby adjust the traffic direction of cardiac catheter head.Take care conductor housing and regulate when arriving the optimum position of passing through valve orifice, the maneuver of going again advances, thereby makes cardiac catheter enter predetermined chamber, further carries out the normal inspection work of cardiac catheter.Get blood, can take a blood sample by multi-joint three-way device and syringe from certain thin cavity.The thought-read internal pressure then can be with multi-joint three-way device and pressure converter connection carrying out pressure measurement inspection.So just, reach the purpose that all use more.
The barrier film of main devices of the present invention-thick conduit and inner chamber thereof can be a rubber, can be plastics etc. nontoxic and macromolecular material anti-sterilisation temp make.The cross section of each the thin cavity in the thick conduit that is separated into by barrier film can be circular, segmental, or semicircular.
This device owing to designed thin cavity spout, just can utilize the retroaction of injection water spray, under perspective, regulates the traffic direction of cardiac catheter head.In practical clinical, the duct portion of this device in heart can be flexibly and easily by various obstructions, and guarantee that normal cardiac work up project carries out.Especially for this device of congenital heart disease disease (lack as room damaged in the heart, or the chamber lacks, or Lu Dengbaha syndrome) by damaged position the time, can make diagnosis clear and definite by defect as long as regulate direction.This device use is quite convenient, can improve the diagnosis accuracy, shortens operating time, has alleviated patient's operation misery greatly.This device can be single the chamber use, also can two-chamber, multi-cavity uses, and carries out different types of inspection respectively.This device has the advantage of multi-use, is a kind of feasible heart medical apparatus and instruments.
