Abstract: A device for at least partially inserting a needle unit into a tissue, the device including a housing, a support with a receiving element and an actuation device, wherein the needle unit is detachably received in the receiving element and the support can be displaced relative to the housing from a first position to a second position in which the needle unit is at least partially inserted in the tissue, and wherein the support is mounted inside the housing so that it can be moved about an axis.

Abstract: A catheter head, for introduction of a fluid into an organic tissue, including a cannula housing with a cannula, a connector element with a fluid inlet, a guide and a fixing device. The guide device has several selectable discrete rotational positions for positioning the connector element relative to the cannula housing about a longitudinal axis of the cannula. The connector element, positioned in a rotational position, is detachably connected to the cannula housing in the selected position by means of the fixing device.

Abstract: A device consisting of a combination of a bathtub (1) with a shower tray (3), in which the bathtub (1), when in position B=Bathing, is positioned over shower tray (3) in such a way that its water outlet ends up over the shower tray (3), whilst when in the other possible position S=Showering, it stands upright, i.e. end over end, on one of its ends, thereby freeing access to shower tray (3). Bathtub (1) can easily be manoeuvred from one position to the other by a lifting mechanism and the application of force, preferably generated by an electric motor (13). By completely separating the bathtub from the shower tray and by positioning the bathtub over the shower tray, the edge of the shower tray is on the one hand kept as low as it would be if there were indeed a separate shower tray, whilst on the other hand, the edge of the bathtub is only slightly raised. As a result, both parts are extremely user-friendly, especially for elderly or handicapped persons.
