The invention relates to an indwelling catheter, in particular an intravenous indwelling catheter for emergency treatment. Said catheter comprises a housing (1) and a puncturing cannula (2), which can be introduced into and removed from the housing interior in the longitudinal direction of the housing (1) and which extends through a front housing opening, in such a way that when said cannula (2) is fully introduced, an entry opening is located outside the housing (1). A collection component (5) stores a blood sample, said component being held in a displaceable manner on the housing (1) with the aid of a fixing element (9) and being displaced between a coupled position, in which a self-replenishing reservoir (7), which is configured in the collection component (5), is in contact with an exit opening of the cannula (2) in order to receive a sample of blood that traverses the cannula (2) and an uncoupled position, in which the reservoir (7) is separated from the exit opening of the cannula (2) and the collection component (5) is held on the housing (1) by means of the fixing element (9).
An indwelling catheter, in particular an intravenous indwelling catheter for emergency treatment, comprising a housing and a puncturing cannula which is removably introduced into a housing interior in the longitudinal direction of the housing and extends through a front housing opening in such a way that an entry opening of the cannula is arranged outside the housing at least in a fully introduced position of the cannula, wherein by a collection component for storing a blood sample, which collection component is held in a movable manner on the housing by means of a fixing element and can be displaced between a coupled position, in which a self-filling reservoir formed in the collection component is connected to an exit opening of the cannula in order to receive a sample of a volume of blood flowing through the cannula, and an uncoupled position in which the reservoir is separated from the exit opening of the cannula and the collection component is held on the housing by means of the fixing element.
