Abstract
A valve is provided for controlling a fluid flow, in particular through a catheter. The valve has a valve control chamber into which an inlet opening of an inlet channel and an outlet opening of an outlet channel open. The valve, further has a closure element which can be moved in the valve control chamber in a controlled manner and which, in at least a first position, closes the outlet opening, in at least a second position closes the inlet opening, and which, in at least a third position, keeps open a connecting channel between the inlet opening day and the outlet opening. The valve further has a valve train that moves the closure element to at least the first, second or third position.
Claims10
A valve for controlling a fluid flow through a catheter, the valve comprising:
- a valve body having a feed opening, a discharge opening, and a connection channel separating the feed opening and the discharge opening;
- a closure element disposed and movable within the valve body, the closure element configured to move between a first position in which the discharge opening is closed, a second position in which the feed opening is closed, and a third position in which the closure element is configured to hold open the connection channel;
- and
- a valve drive comprising a magnetic field productive device and a drive lever;
- and
- an elastic spring element,
- wherein the drive lever extends along an axis from a first end to a second end, wherein the first end of the drive lever is disposed in the valve body and forms a portion of the closure element,
- wherein the drive lever is pivotable in a clockwise direction or a counterclockwise direction about a pivot point intermediate of the first end and the second end of the drive lever,
- wherein a part of the drive lever is configured as a magnetic element and the magnetic field productive device is configured to produce a magnetic field that interacts with the magnetic element of the drive lever to pivot the drive lever and move the closure element to the first position or the second position,
- wherein the elastic spring element is connected to the second end of the drive lever and configured to hold the closure element in the third position when the magnetic field productive device is not producing the magnetic field.
