Abstract
Disclosed is a swirling guided vena cava filter, which is characterized in that: the front end of a filter screen 2 is connected with a swirling guided tube 1 whose inner wall is in spiral. The utility model is suitable to the patients with coronary heart disease, and is arranged in a vena cava vessel 3 of the human body, which is helpful for the blood to flow following the swirling direction of the swirling guided tube 1, so that the circulating sectional area is increased. Thrombus stopped by the filter screen 2 can be dissolved fast with the stirring of the swirling. Meanwhile, the vessel wall can be washed smoothly by the swirling blood; the thickness of the thrombus layer is reduced, so that the acute thrombus blocking is prevented effectively.
Description
One, technical field:
This utility model relates to a kind of medical device, especially the swirling flow lead-in cavity vein filter of guide blood flow.
Two, background technology:
In order to help blood fat height and thrombosis patient's blood flow, at present, the normal method of installation cavity vein filter screen that adopts makes the blood flow mediation in the body cavity vein blood vessel.Because can only catching thrombosis, this filter screen flows no longer backward, can not thrombus, and when blood flow rate was lower than thrombotic critical velocity, thrombosis can finally cause blood vessel to stop up fully in the very fast accumulation of artificial blood vessel inwall.
Find after deliberation, the shape of human aortic bow exactly likes a umbrella that reverses, its bending is the space three-dimensional helical form fortunately, the structure of this space three-dimensional spiral just, it is moving to make the blood flow at ascending aorta place be binary vortices, and to be that the ascending aorta vascular wall is smooth wash away in case the guarantee that the stop pulse atherosclerosis forms for it.
Three, summary of the invention:
The purpose of this utility model is to provide a kind of swirling flow lead-in cavity vein filter by the shape facility that human aortic bends, and solves body cavity vein blood vessel place blood flow problem.
Concrete scheme of the present utility model is: a kind of swirling flow lead-in cavity vein filter, in the caval vein blood vessel, filter screen is housed, and it is characterized in that: connect the swirling flow guide wire at the filter screen front end, the inwall of swirling flow guide wire is shape in the shape of a spiral.
Adopt such scheme, have following advantage:
1. blood is flowed by hand of helix, thereby improve actual internal area.
2. because the stirring action of swirling flow can make the thrombosis accelerate dissolution of being caught by filter.
3. the blood of swirling flow can make blood vessel wall obtain smooth washing away, and reduces the thickness of thrombosis layer, prevents that effectively acute thrombus from stopping up.
Four, description of drawings:
Fig. 1 is a structural representation of the present utility model.
Five, the specific embodiment:
As shown in Figure 1: this utility model mainly is made up of swirling flow guide wire 1, filter screen 2, and numbering 3 is caval vein blood vessels of human body among the figure.Architectural feature of the present utility model is: connect swirling flow guide wire 1 at filter screen 2 front ends, the inwall of swirling flow guide wire 1 is shape in the shape of a spiral.This utility model is installed in the caval vein blood vessel 3, helps blood to flow by the rotation direction of swirling flow guide wire 1, makes the thrombosis accelerate dissolution of being caught by filter screen 2, thereby prevents that acute thrombus from stopping up.
Claims (1)
1. a swirling flow lead-in cavity vein filter is equipped with filter screen (2) in caval vein blood vessel (3) lining, it is characterized in that: connect swirling flow guide wire (1) at filter screen (2) front end, the inwall of swirling flow guide wire (1) is shape in the shape of a spiral.
