  • Patent number: 10596351
    Abstract: A self-sealing catheter valve that includes a flexible tubular part having a distal opening and an opposite proximal opening, and a proximal valve part. The proximal valve part has a curved self-sealing flexible diaphragm disposed inside the flexible tubular part and has a base perimeter united with a circumferential wall of the flexible tubular part. The curved self-sealing flexible diaphragm has a concave surface facing towards the proximal opening, and a convex surface facing towards the distal opening, and a flexible diaphragm wall of the curved self-sealing flexible diaphragm has a traverse slit. The self-sealing catheter valve provides an efficient self-closing mechanism for a peripheral catheter assembly and constitutes an efficient barrier against potential contagious spread from the patient to the surrounding environment by blood born disease e.g. HIV, hepatitis and Ebola viruses.

  • Patent number: 9199062
    Abstract: An inserter assembly for a peripheral catheter assembly configured with an adhesive plaster member, wherein the catheter tube extends through the plaster member. The inserter assembly includes a first inserter part having first and second legs, a bridge member connecting the first and second legs at a distance from each other, with the bridge member adapted for detachably engaging or holding at least a part of the needle module extending coaxially between the first and second legs. The inserter assembly includes a second inserter part for covering the needle. The plaster member impairs visual sight and the line of vision to the needle tip during puncture may be impaired. To prevent this the first inserter part serves for holding a back-folded part of the plaster member.

  • Patent number: 9167997
    Abstract: The invention relates to a method and arrangement for continuously measuring substances in a pressurised body fluid. A probe (202) for enabling continuous measurement of the concentration of one or more substances in a pressurized body fluid is provided. The probe is adapted to be inserted into the pressurized body fluid, and comprises an interface and an outlet lumen. Furthermore, the probe is configured so that a continuous and spontaneous fluid flow is established from the body fluid through the interface to the outlet lumen. The fluid flow from the outlet may be analyzed by a sensor.

  • Publication number: 20120088225
    Abstract: Methods of detecting major ischemic complications in critically ill patients comprise a) determining the blood concentration of glycerol at least once per hour; b) comparing the obtained blood concentration of glycerol with a defined critical level; and c) based on the comparison of step b), identifying patients experiencing or being at risk for major ischemic complications in order to select such patients for intensified surveillance and treatment. The methods allow early and reliable detection of major ischemic complications and identification of patients at risk for prolonged stay at an intensive care unit. The patients preferably have undergone surgical intervention with a following reperfusion or can be patients suffering from the complications of a trauma at an intensive care unit, or have undergone cardiac surgery.

  • Patent number: 6811542
    Abstract: A microdialysis probe and catheter arrangement includes a catheter carrying in a distal end thereof a probe to be inserted in the body of a living being. The catheter has an elongate catheter body including a first channel for supplying a first fluid and a second channel for returning said first fluid. The first and second channels extend internally along the catheter body from a proximal end thereof to the probe. The probe includes a microdialysis membrane defining a dialysis chamber communicating with the first and second channels. A third channel extends internally along the catheter body and communicates with the second channel to supply a second fluid to thereto, thereby to increase the flow rate therein.

  • Publication number: 20040162610
    Abstract: A device for correcting mitral and tricuspid valve regurgitation. The device connects the leaflet bases of the posterior and anterior mitral leaflets to each other with a stabilizing element extended transversely across the valve annulus. The stabilizing element is by first and second ends secured into a first and a second position respectively at the valve annulus using sutures, anchors or clips. Coaptation is attained, by reducing the length of the stabilizing element.
