Abstract: The syringe for transferring a medical substance from a container (10) provided with an elastomeric closure into an infusion container has a plastic syringe body (1). In order to avoid the danger of injury to a user by medical hollow needles previously used on syringes, a plastic hollow peg (9) is arranged at the front end of the plastic syringe body (1) instead of the typical sharp hollow needle. However the plastic hollow peg (9) is formed so that it can pierce the elastomeric closure (11) of the container (10). The hollow peg (9) is preferably in one piece with the syringe body (1). A transfer arrangement including a syringe (1), a preparation container (10) and a holder (10a) that holds the syringe on the preparation container is also described.

Abstract: The process for applying a thermally attached lubricating coating on an interior wall of a cylindrical medicinal container includes applying a thermally attachable lubricant to an interior wall of the container; uniformly spreading or homogenizing the applied lubricant on the wall to form a lubricating coating and thermally attaching the lubricating coating by irradiating the lubricating coating with infrared radiation selectively in a cylindrical region of the container at elevated temperatures above a maximum operating temperature of the container. The apparatus for performing the process includes an insertable spraying device for applying the thermally attachable lubricant (3) to the interior wall of the container (1) from a supply reservoir; a device for homogenizing the lubricant to form the lubricating coating (4) and a rod-shaped infrared radiation source (5) insertable into an interior space of the container.

Abstract: A metering receptacle has an elongate hollow body which at one end has a closable exit opening, and which at the other end is closable by way of a plastic plunger stopper. The plunger stopper is at the same time longitudinally displaceable in the hollow body by way of a plunger rod. The metering receptacle is configured such that the plunger stopper is formed of two parts, with a sealing stopper part of plastic which is rigidly positionable in the elongate hollow body and has a centric bore for the passage of the plunger rod, and with a longitudinally displaceable plunger part of lubricious plastic which is connected to the plunger rod.

Abstract: Syringes for medical purposes have syringe bodies which typically have a syringe body (2) on which a syringe head (3) is formed at the outlet end. A finger support (1) is at the other end. This finger support has an enlarged support surface in two mirror-symmetrical opposite-lying regions. To increase the support surface further, the finger support (1) is so configured that the two regions (1a, 1b) have a parabola-shaped configuration whose respective apexes are directed away from the syringe body (2). The two regions go over one into the other in the region (1c, 1d) of the mirror axis in an arcuate shape. In this way, the ergonomic manipulation of the syringes is improved and a high packing density of the syringes when magazining is made possible.

Especially this method avoids or minimizes the amount of droplets of silicone oil fed into the contents of the hollow plastic body (1).

Abstract: The invention consists of a glass bottle (1) fitted with a narrowed neck (2) which can be filled under pressure with chiefly a medically active substance sprayable by aerosol and with a propellant and which exhibits an opening which may be closed using a dosage valve (5). This glass bottle (1) has a sprayed on synthetic coating (4) to protect it against shattering and splintering, preventing the user from being injured by the broken bottle. To substantially enhance this safety, the neck (2) of the bottle (1) has been fitted with a bulge like edge (3) at the opening which is also coated with the synthetic material (4) and onto which the dosage valve (5) is mechanically attached by turning. Furthermore, the coating (4) consists of an elastic synthetic material with pronounced increased shrinkage properties used for the summoning of pre-stressing force on the glass body (1) and it exhibits several hole like pressure relieving openings (7) permitting rapid pressure release in case of shattering.

Abstract: The piston burette for storing and dispensing a reagent used in analytical or metering work includes a calibrated burette cylinder (11) and a piston (13) slidably mounted in it.

Abstract: Medical cannulas are typically provided with a silicone coating to improve incision performance. In order to produce a thin, continuous and even coating layer, silicone oil is provided at one side of an elastic foil and the foil is penetrated by the uncoated cannula from an opposite side. During this operation the cannula is wetted by the silicone oil. During withdrawal of the cannula from the foil, excess silicone oil is removed from the cannula and an even, particle-free thin coating which has no bulge- or bead-forming tendency during incision is obtained. Subsequently, the silicone coating is dried.
