摘要:
For the administering of medicaments, an adapter is provided for connection to a haemodialysis tube set, which makes possible the direct connection of a standard injection vial to the extracorporeal circuit, avoiding the introduction of air into the circuit. The adapter has two conduit pathways. The conduit pathway for the application of medicament contains a gas-blocking element. The second conduit pathway serves for the aeration of the injection vial.

摘要:
A high power laser source comprises a bar of laser diodes, a submount onto which said laser bar is affixed, and a cooler onto which said submount is affixed. The laser bar has a first coefficient of thermal expansion (CTEbar), the submount has a second coefficient of thermal expansion (CTEsub), and the cooler has a third coefficient of thermal expansion (CTEcool) the third coefficient (CTEcool) being higher than both said first coefficient (CTEbar) and said second coefficient (CTEsub). Contrary to the usual approach with a CTEsub matching the CTEbar, the second coefficient (CTEsub) is selected lower than both said first coefficient (CTEbar) and said third coefficient (CTEcool) according to the invention. A preferred range is CTEsub=k*CTEbar, with 0.4

摘要:
A filter element formed of a pleated filter medium (11) and having a seal or gasket element (15) on its periphery or end faces. On one side of the filter element, which may represent either the inlet or the outlet side of the filter element, at least one adhesive track or reinforcing member (12, 13, 14), and preferably at least two adhesive tracks or reinforcing members (12, 13, 14), is/are arranged in such a way that the filter element can be bent to a curved configuration in one direction.
摘要:
An optically controllable microelectrode array for stimulating cells within a tissue is disclosed. The array comprises a substrate having a surface. The substrate is adapted to be placed on the tissue with the surface adjoining the cells. The substrate further comprises a plurality of electrodes on the surface in contact with the cells for stimulating the cells. The electrodes are dimensioned such that a first surface area on the electrodes in contact with the cells is essentially smaller than a second surface area on the cells in which the cells may be contacted by the electrodes. An electrical stimulus is exerted from the electrodes to the cells under the control of light impinging on the tissue.
