Embodiment Construction

[0054] figure 1 A perspective view of a valve device 1 according to the first aspect of the invention is shown. The valve device 1 is adapted to be detachably secured to an access port such as that described in WO2011 / 150978; the access port disclosed in WO2011 / 150978 is used to remove fluid and / or return fluid to the patient.

[0055] The valve arrangement 1 comprises two valves 4a, 4b selectively operable in an open configuration or a closed configuration (in figure 1 Indicated as a slit valve). The two valves 4 a , 4 b are accommodated in the housing 2 of the valve device 1 . In use, the first valve 4a of the valve arrangement may be connected to a first conduit which may deliver fluid to the patient, and the second valve 4b of the valve arrangement 1 may be connected to a second conduit which may deliver fluid from the patient. When the valves 4a, 4b are in the open configuration, they will allow fluid communication between the access port and the patient. When the val...

Abstract

According to the present invention there is provided a valve device (1) suitable for detachably fixing to an access port, the valve device (1) comprising, a fixation clip (3) which comprises at least a first and second fixation member (3a, b) each of which comprise one or more rims (8) each of which have a surface (9) which veers in a direction towards the valve device (1). There is further provided a removing tool (10) for removing the valve device (1) from an access port, comprising at least two elements (11a, b) each of which can be arranged to abut with said surface (9) of a rim (8) of a respective fixation member (3a, b) in the valve device (1), wherein the elements (11a, b) are fixed in the removing tool (10) so that the fixation members (3a, b) are moved apart by the elements (11a, b) by advancing the removing tool (10) towards the valve device (1). There is further provided a mounting tool (20) for mounting a valve device (1) in an access port, the mounting tool (20) comprising, a cavity (21) suitable for receiving a valve device (1), and a holding clip (22) into which the fixation members (3a, b) of a valve device (1) can clip only when the fixation members (3a, b) are flexed apart. An assembly comprising a mounting tool (20) and a valve device is also provided.

Description

technical field [0001] The invention relates to a valve arrangement, a corresponding removal tool usable for removing the valve arrangement from an access port and a corresponding installation tool usable for installing the valve arrangement on the access port. There is further provided a valve arrangement, the tool being cooperable with the valve arrangement. Background technique [0002] Access ports such as those described in WO2011 / 150978 contain valve means that typically require periodic replacement. Removing these valve arrangements is difficult and requires high dexterity. Removal of these valve arrangements can also be dangerous due to loss of blood or aspiration of air into the patient's blood system. Therefore, positioning a new replacement valve device on the access port is also difficult and requires high flexibility. [0003] It is an object of the present invention to alleviate or eliminate at least some of the above-mentioned problems. Contents of the in...
