FIELD: medicine.
SUBSTANCE: invention refers to medical equipment, namely to a catheter device. The catheter device comprises a hollow bushing of the catheter; a canal radially extending from the bushing of the catheter between proximal and distal end; a first valve element in the bushing of the catheter; a second valve element. The distal end of the bushing is attached to the catheter. For the purpose of providing an option, there is a coupler at the proximal end of the bushing. The first valve element closes the ready valve and unblocks a junction of the canal and the catheter after exerting external pressure to the channel. The second valve element is presented in the form of a two-way valve generating a through fluid flow in both directions. The through flow in the proximal direction is enabled when exerting intake pressure from the proximal side of the second valve element.
EFFECT: invention also enables running the fluid off, mainly blood.
