摘要:
A wound dressing comprising a web of gel-forming fibers or fibers soluble in wound exudates, attached to a reinforcing layer wherein the density of the web is in the range of 5-60 g/m2. The dressing may serve as a wound-contacting layer, providing moist wound healing combined with easy, non-traumatic removal from the wound site. The dressing may further comprise one or more active ingredients.

摘要:
A method of manufacturing a coated needle electrode comprising the steps 5 of holding an uncoated sharpened needle by the tip, dipping the uncoated sharpened needle into a bath of coating material, and withdrawing the sharpened needle from the bath of coating material. In this way, the coating can be applied after the needle has been sharpened thereby allowing more precision during the sharpening process. The invention also provides an apparatus for use with the method.

摘要:
We add discontinuous regions of Extra Cellular Matrix (ECM) to a biodegradable scaffold. Hereby it is possible to combine the range of physical properties the scaffold can offer with the reconstructive properties of the ECM. The optimal amount of discrete ECM material for each application is disclosed and this concentration is equally distributed in the dressing hence avoiding unnecessary high concentrations of ECM. In addition to the effect of the ECM, the porous structure of the base material provides the cells with a structure for in-growth.

The present application discloses biodegradable polymers, to porous and other materials comprising such polymers, and to various medical uses of such materials, including use as a scaffold for supporting cell adhesion or the in-growth for regeneration of tissue. The polymer is of the formula A—O—(CHR1CHR2O)n-B wherein A is a poly(lactide-co-glycolide) residue, the molar ratio of (i) lactide units [—CH(CH3)—COO—] and (ii) glycolide units [—CH2—COO—] in the poly(lactide-co-glycolide) residue being in the range of 80:20 to 10:90, B is either a poly(lactide-co-glycolide) residue or hydrogen, C1-6-alkyl or hydroxy protecting groups, one of R1 and R2 is hydrogen or methyl, and the other is hydrogen, n is 10-1000, the molar ratio of (iii) polyalkylene glycol units [-(CHR1CHR2O)—] to the combined amount of (i) lactide units and (ii) glycolide units in the poly(lactide-co-glycolide) residue(s) is at the most 14:86, and the molecular weight of the copolymer is at least 20,000 g/mol.
摘要:
A valve assembly (2) forming a bridge circuit and a hydraulic actuator comprising at least one valve assembly (2) are disclosed. The valve assembly (2) is fluidly connectable between a fluid source (3) and a fluid drain (4). The valve assembly (2) comprises a first valve (8) fluidly connected between the fluid source (3) and a first diagonal point (12) of the bridge circuit, a second valve (9) fluidly connected between the fluid source (3) and a second diagonal point (13) of the bridge circuit, a third valve (10) fluidly connected between the first diagonal point (12) and the fluid drain (4), and a fourth valve (11) fluidly connected between the second diagonal point (13) and the fluid drain (4). The valves (8, 9, 10, 11) are such that in the case of a power cut off, flows of fluid away from the diagonal points (12, 13) are prevented. Thereby a hydraulic servomotor (5) connected across the diagonal points (12, 13) will be hydraulically locked in its instantaneous position, and a safety feature is accordingly provided. The first valve (8) and the second valve (9) are furthermore of a kind which is closed in an energized state. Thereby it is possible to control the valve assembly (2) in such a manner that a piston member (14) of a servomotor (5) connected across the diagonal points (12, 13) can be moved at a high velocity, thereby providing a servomotor (5) having a quick response time.
摘要:
A medical dressing comprising a complex of silver and being capable of releasing antimicrobial silver ion activity, the complex comprising silver ion, a transition element of Group IV of the periodic system of elements, cation, phosphate and hydrogen to enable a controlled release of silver ion activity to a wound bed.
摘要:
The invention concerns a valve arrangement for controlling a hydraulic drive having a first working connection (A) and a second working connection (B), and being connectable with or separable from a pressure source (P), the supply and the outflow of the hydraulic drive being separately controllable. It is endeavoured to improve the energetic efficiency of the valve arrangement. For this purpose, the first working connection (A) is connected with a first control valve and the second working connection (B) is connected with a second control valve, the first and the second control valves being connected with each other and with a third control valve, which is connected with a tank.
