摘要:
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.

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.

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.
摘要:
A method of manufacturing a microdialysis catheter, comprises the steps of extruding a flexible material to form an elongate catheter body having a substantially cylindrical outer surface and a plurality of continuous internal channels extending in the longitudinal direction of said catheter body; sealing a free end of said catheter body; providing in said surface at a distance from said free end an opening extending into said catheter body to communicate with a portion of a first of said channels; providing communication between said first channel and a second of said channels at a distance from said free end shorter that said distance; and covering said opening by a microdialysis membrane.

摘要:
A transcutan catheter assembly including a catheter having a distal end and a proximal end, and a collar of a relatively flexible material having an upper surface and a lower surface. The catheter extends in a fluid tight manner through the collar such that the distal end of the catheter protrudes underneath the lower surface of the collar and its proximal end is accessible at the upper surface for the connection of tubing to the catheter. The lower surface of the collar has adhesive properties for fluid tight attachment to the skin of a patient.
摘要:
A catheter for insertion into a blood vessel of a living being, which includes an elongated catheter body and membrane defining a dialysis chamber; a first channel provided for delivery of dialysis liquid to the dialysis chamber and a second channel provided for the discharge of dialysis liquid from the dialysis chamber, wherein the dialysis chamber comprises a plurality of tubular members, each having an inlet end and an outlet end, all the inlet ends being connected to the first channel and all the outlet ends being connected to the second channel.

This invention relates to a composition and procedure for manipulating the behaviour of nun moth, Lymantria monacha (L.) and gypsy moth, Lymantria dispar (L.). More particularly, this invention relates to the preparation and use of chiral and racemic disparlure, chiral or racemic cis-7,8-epoxy-octadecane, 2-methyl-Z7-octadecene and Z7-octadene for manipulating the behaviour of nun moth and gypsy moth. A composition of chemicals for manipulating the behavior of nun moth and/or gypsy moth, said composition comprising two or more chemicals selected from the group consisting of: (a) 2-methyl-7R,8S-epoxy-octadecane (RS-disparlure); (b) 2-methyl-7S,8R-epoxy-octadecane (SR-disparlure); (c) 7R,8S-epoxy-octadecane; (d) 7S,8R-epoxy-octadecane; (e) 2-methyl-Z7-octadecene; and (f) Z7-octadecene.
