Abstract: A catheter coupling has a tubing and two jaws extending in the longitudinal direction of the tubing which form a channel having an orifice to accommodate an end section of a catheter when the jaws abut against each other. The jaws are interconnected at a respective jaw end via a jaw joint having a joint axis extending transversely to the tubing. The other jaw end includes a snap-in locking member and a counter snap-in locking member, respectively, interacting therewith to form a snap-in locking arrangement. In the engagement position, the tubing is deformed by at least one jaw deformation component to securely accommodate the catheter. The coupling has at least one inspection window that allows a stop in the tubing for the end section of the catheter to be visually inspected to prevent an end section of the catheter from being introduced into the tubing if it is too short.

Abstract: A device for administering a bolus, includes an actuating element to actuate a closing mechanism which opens and closes a hose segment. The hose segment can be connected to a fluid source and to a patient. The device also includes a movable element, a blocking element which locks the movable element in an upper position and which can be released by the actuating element, an elastic element which pushes the actuating element and movable element apart, a first actuation blocking element which locks the actuating element in a lower position and can be released by the movable element, and a bolus reservoir for holding a bolus quantity of fluid. The volume of the bolus reservoir can be reduced by displacing the movable element. A second actuation blocking element locks the actuating element in the upper position can be released by the movable element.

Abstract: The invention relates to the use of polymeric or oligomeric active ingredients having a biocidal effect as additives in the composition of medical articles. The invention further relates to medical articles that comprise such additives.

Abstract: A catheter coupling has a tubing and two jaws extending in the longitudinal direction of the tubing which form a channel having an orifice to accommodate an end section of a catheter when the jaws abut against each other. The jaws are interconnected at a respective jaw end via a jaw joint having a joint axis extending transversely to the tubing. The other jaw end is in each case provided with a snap-in locking member and a counter snap-in locking member, respectively, interacting therewith to form a snap-in locking arrangement. In the engagement position, the tubing is deformed by at least one jaw deformation component to securely accommodate the catheter end section. The catheter coupling has at least one inspection window in a base body. The inspection window allows a stop in the tubing for the end section of the catheter to be visually inspected. As a result, a catheter coupling is obtained which prevents an end section of the catheter from being introduced into the tubing if said end section is too short.

Abstract: A spinal cannula with a needle hub having a transparent area for observing the liquor flowing through a hollow cavity of the needle hub. A structure for refracting or reflecting rays of light is provided in or at the transparent area of the needle hub. The structure for refracting or reflecting rays of light may be formed as one or more prisms.

Abstract: The invention relates to a wound dressing comprising a polymer substrate and a compound comprising a) at least one antimicrobial active agent and b) an agent that reduces the cytotoxicity, comprising an oil-in-water emulsion that additionally has one or more alkanediol(s) and/or one or more glyceryl ether(s).

Abstract: The invention relates to the use of at least one polymeric guanidine derivative having a biocidal effect, which can be obtained by polycondensating a guanidine acid addition salt with an amine mixture containing at least one diamine, which is selected from the group consisting of alkylene diamine and oxyalkylene diamine, as an additive in a composition for medical articles. The invention further relates to medical articles containing polyguanidines as an additive.

Abstract: To further improve, under ultrasonic observation, the visibility of a medical instrument with at least one portion of the instrument that can be inserted into body tissue of a patient and has a surface structure reflecting ultrasound waves, wherein the surface structure comprises a number of reflection elements, it is proposed that at least three, and at most nine, reflection elements which are arranged in a defined way in relation to one another define a reflection element group and that the surface structure comprises at least two reflection element groups.

Abstract: A spinal cannula with a needle hub having a transparent area for observing the liquor flowing through a hollow cavity of the needle hub. A means for refracting or reflecting rays of light is provided in or at the transparent area of the needle hub. The means for refracting or reflecting rays of light may be formed as one or more prisms.

Abstract: The catheter provided in accordance with aspects of the present invention includes an elongate tube having a proximal tube portion and a distal tube portion formed by stretching the distal portion of the elongate tube. The catheter is made throughout from an identical material. The distal tube portion has a reduced outer diameter and thus is of a higher flexibility and softness. Therefore, the danger of injuries to vessels or the dura is decreased. The catheter can be produced in an inexpensive and simple manner.

Abstract: The syringe pump comprises a housing (10). The operating panel (32) is situated on a swiveling lid (30) on the front side of the housing (10). The lid (30) further comprises a window (34) with a magnifying device (35) through which the user can view the syringe. The invention allows for a miniaturization of the syringe pump in a highly densified modular system. The lid (30) may further include a lighting means for illuminating the syringe.

Abstract: device for administering liquids comprises an administering part (10) and an adhesive plaster (11). The administering part (10) is connected with a cannula stud (30) and an administering line (14) and carries a liquid. For fastening the administering part (10) to the surface of a patient's skin or the surface of an object the adhesive plaster (11) is stuck on the surface. The adhesive plaster (11) is provided with a plug-in pin (38) which is adapted to be inserted into an insertion opening (43) of the filter (10). By placing the filter (10) onto the plug-in pin (38) the administering part (10) is detachably connected with the adhesive plaster (11). If the administering part (10) is a filter with transparent housing the filter membrane is well visible since the latter is not covered by adhesive strips when the filter is fastened to the patient's body.
