Abstract
The invention relates to a fastening member (1) which is placed into a patient's cavity, such as a nostril, surrounded by tissue, and which allows a flow through the cavity through a port (5) and which can be joined to the measuring device via a suitable connecting piece (2). The fastening member (1) is flexible, whereby it can be formed, before being placed into the cavity, into a shape or size which fits better into the cavity, whereupon the fastening member, in the cavity, tends to return towards the original state by pressing against the surrounding wall of the cavity.
Claims13
A fastening member (1) adapted to be placed in a passage of a patient for positioning a sampling means in the passage, said sampling means for conducting fluid samples to a measuring device, said passage being accessible from outside the patient's body and being lined with tissue, said fastening member comprising:
- a tube formed of a deformable, resilient material, said tube having a port (5) extending therethrough parallel to a longitudinal axis of the tube, said tube being deformable by manual manipulation to facilitate placement in the passage, the resiliency of said tube tending to cause said tube to return to the undeformed state and to press against the tissue of said passage for retaining said tube in said passage, said port forming a fluid communication path through the tube to outside the patient's body for a medium in the passage when the fastening member is placed in the passage;
- and
- a connecting member (3) disposed inside said tube and attached to said tube for receiving the sampling means so that the sampling means may sample the medium in the passage.
