Abstract
The utility model relates to a medical device, in particular to cardiac intervention guiding device, having a flexible tube, and is characterized in that: one end of the flexible tube is closed and takes on an arc greater than semicircle, a plurality of through holes are arranged on the wall of the curved tube, the other end of the flexible tube is respectively connected with a drug infusion guide tube and a liquid accumulation guide tube by a three-way valve, and the drug infusion guide tube and the liquid accumulation guide tube are respectively mainly provided with a control valve. The utility model has the advantages of simple structure, convenient operation and safe use. Because the flexible tube is adopted and the front end is closed, the heart will not be stimulated or damaged, making the pericardial puncture become relatively safe. Because the flexible tube front end takes on an arc greater than semicircle, the utility model is made convenient for indwelling, to at any moment extract fluid accumulation or inject drugs in the pericardial cavity by the tube to carry on therapies. Because a plurality of through holes are arranged on the wall of the curved tube, the guide tube can be prevented from being blocked to ensure the clearance of drainage and drug injection.
Description
Technical field:
This utility model relates to medical apparatus, and specifically a kind of heart is got involved guiding device.
Background technology:
We know, pericardial effusion belongs to the commonly encountered diseases of heart, frequently-occurring disease, pericardiocentesis drainage lavation technology is the state-of-the-art technology of heart internal medicine interventional therapy, paracentesis pericardii extracts hydrops and makes lab testing, alleviates the pericardium pressure symptom simultaneously, and cardiac's diagnosis and treatment had great importance, the used conduit of pericardiocentesis drainage is a pigtail catheter at present, because the front end of pigtail catheter is thinner and crooked, side opening is few and the aperture is little, is stopped up by the floccule in the pericardial effusion easily, make and get involved failure, what have cuts the pigtail front end, and after puncture entered pericardium, the pigtail front end may touch heart, cause arrhythmia, coronary artery injury, even rupture of heart, thus dead, there is not by-pass valve control on the pigtail in addition, can not control the drainage of pericardium amount, be prone to the Hypovolemia reaction, serious threat patient's life, there is not by-pass valve control, inject intrapericardial medicine and easily flow out, influence therapeutic effect, also do not have the special-purpose guiding device of heart intervention treating in the prior art with hydrops.
Summary of the invention:
The purpose of this utility model provides a kind of heart easy to operate, safe in utilization and gets involved guiding device.
This utility model can reach by following measure:
A kind of heart is got involved guiding device, the flexible pipe that is provided with, it is characterized in that flexible pipe one end sealing and be arc greater than semicircle, the arc tube wall is provided with some through holes, the flexible pipe other end is connected with the hydrops conduit with injection catheter respectively through three-way valve, mainly is provided with by-pass valve control on injection catheter and the hydrops conduit respectively.
This utility model can be provided with scale mark on flexible pipe, be used for determining flexible pipe length in vivo, avoids coming off.
This utility model is owing to adopt said structure, have advantages such as simple in structure, easy to operate, safe in utilization, owing to adopt the sealing of flexible pipe and front end, the step can stimulate or the damage heart, makes paracentesis pericardii become comparatively safe, owing to be arc before the flexible pipe greater than semicircle, make it easy to keep somewhere, to extract hydrops at any time or to inject medicine through this pipe to the pericardium intracavity and treat, because the arc tube wall is provided with some through holes, can avoid conduit blocked, to guarantee the unobstructed of drain, injection.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
Below in conjunction with accompanying drawing this utility model is further described:
As shown in drawings, a kind of heart is got involved guiding device, the flexible pipe 1 that is provided with, it is characterized in that the end sealing of flexible pipe 1 and be arc greater than semicircle, the arc tube wall is provided with some through holes 2, the flexible pipe other end is connected with hydrops conduit 5 with injection catheter 4 respectively through three-way valve 3, mainly be provided with by-pass valve control 6 on injection catheter 4 and the hydrops conduit 5 respectively, 7, injection catheter 4 is connected with syringe, treat in pericardium, to inject medicine, hydrops conduit 5 is connected with drainage bag, in addition, this utility model can be provided with scale mark on flexible pipe, be used for determining flexible pipe length in vivo, avoid coming off, the utlity model has simple in structure, easy to operate, advantage such as safe in utilization, owing to adopt the sealing of flexible pipe and front end, step can stimulate or the damage heart, make paracentesis pericardii become comparatively safe,, make it easy to keep somewhere owing to be arc before the flexible pipe greater than semicircle, to extract hydrops at any time or to inject medicine through this pipe to the pericardium intracavity and treat, because the arc tube wall is provided with some through holes, can avoid conduit blocked, to guarantee drain, injection unobstructed.
