Embodiment Construction
[0071] figure 1 A perspective general view of the catheter 1 is shown. In order to provide direct access to, for example, the stomach or intestine of a patient for enteral nutrition, the catheter may be percutaneously inserted through the patient's abdominal or intestinal wall. To this end, the catheter 1 has a hose system comprising an outer hose 16 and an inner hose 15 which is connected at its proximal end to a proximal piece 17 and at its distal end to the holding devices 12, 13. The catheter 1 should pass through the opening of the patient's abdominal wall with the distal end 1B, and the proximal end 1A of the catheter 1 is located outside the patient's body with the catheter 1 indwelled, so that through the proximal piece 17, a conductive system or, for example, a nutrient solution container can be connected To the catheter 1 for enteral nutrition of the patient.
[0072] The holding devices 12, 13 are used to hold the catheter 1 in its prescribed position and prevent the c...

The invention relates to a catheter (1) for enteral nutrition of a patient, comprising: a hose section (16) extending at least partially in the axial direction (S) and having a proximal end (161) and distal end (160); and retaining means (12, 13) disposed on the distal end (160) of said hose section (16), said retaining means being compressed in at least one diameter Projects in the direction of the axial direction (S) beyond the distal end (160) of the hose section and has a radially smaller dimension in the elongated state in which the retaining device is compared to the compressed state (12, 13) are elongated in said axial direction (S) and the holding means (12, 13) can be transformed from a compressed state into an elongated state with the cooperation of the operating means (2). It is provided here that the hose section is formed by an outer hose ( 16 ) and that an inner hose ( 15 ) with a proximal end ( 151 ) and a distal end ( 150 ) is arranged within the outer hose ( 16 ), said The inner hose (15) is connected with the operating member (10) at its distal end (150) and is elastic in the axial direction (S), so that the operating member (10) can move in the axial direction relative to the outer hose (16). (S) Movement to transform the holding means (12, 13) from a compressed state to an elongated state. In this way, a catheter for enteral nutrition of a patient is provided which can be easily left in place and easily replaced.
Description
Technical field [0001] The invention relates to a catheter for enteral nutrition of patients. Background technique [0002] Such a catheter includes a hose section with a proximal end and a distal end extending in the axial direction at least in a partial area, and a retaining device provided on the distal end of the hose section. The retaining device here has a compressed state and an elongated state: in the compressed state, the retaining device protrudes from the distal end of the hose section at least in a direction radial to the axial direction, while in the elongated state the retaining device It is elongated in the axial direction and has a radially smaller size compared to the compressed state. The holding device can be activated or deactivated under the cooperation of the operating device, that is, the holding device transfers from the compressed state to the elongated state or vice versa from the elongated state to the compressed state. [0003] Such a catheter can, for...
