Problems solved by technology

As mentioned above, such sterile closure elements are still disadvantageous because of the possibility of producing sharp edges and fragments of the sterile closure element, which could lead to damage to blood components
Another disadvantage of the device described in WO 2004 / 058046A2 is that the mechanism described is rather complex, since the actuator has to be constantly moved back and forth
It is also not suitable for use as a hand tool for opening sterile locking elements

Embodiment Construction

[0043] figure 1 A part 100 of a blood treatment device for cell separation is shown in a perspective view. On its front side, the device has an opening device 10 for opening a locking element such as that described in DE 10 2005 019 855 A1. In this regard reference is made to this patent document.

[0044] The opening device 10 is activated by a processor unit (not shown in detail) of the blood treatment system at a predetermined point in time, so that the locking element is compressed and thus the catheter is opened.

[0045] Figure 2a The opening device 10 is shown in an enlarged perspective view; Figure 2b shows an exploded view of the device. The housing of the device is indicated with reference number 12 . Reference numeral 14 designates two clamp-fitting elements of a mechanism which prevents the hose section from being inserted only partially into the opening device 10 shown. Such as Figure 2b As shown in , the two jaws 14 are loaded by a spring 19 . The two ...

Abstract

The present application relates to a device for opening a line, particularly the line of a blood tube or blood bag system, wherein the line has a sealing element that blocks the line passage, wherein the device comprises at least one opening unit (10) that is configured such that the same exerts a force acting upon the line from the exterior, whereby the sealing element is pressed together and the line is opened. The opening unit is contoured such that the line can be inserted into the opening unit only such that the force acting upon the line is exerted exclusively, or at least also in the region, in which the locking element is located.

Description

technical field [0001] The invention relates to a device for opening a catheter, in particular a catheter of a blood hose system or a blood bag system, which has a blocking element which blocks the throughflow of the catheter, the device having at least one opening device, the opening device being designed In order to apply a force acting on the catheter from the outside, whereby the locking element is compressed and the catheter is opened. Background technique [0002] Such a device for opening a catheter is known, for example, from DE 10 2005 019 855 A1. The opening device disclosed in this patent document comprises two jaws which can be closed mechanically or manually. The duct section located between the two jaws is compressed and the closure element is plastically deformed, so that a free flow cross section is created in the duct and remains free even after the opening device has been actuated. [0003] Healthcare and blood bank personnel are often required to handle ...
