A catheter holding device having longitudinally-extending walls defining an open-ended body with a main passage therethrough. At least a portion of the main passage is aligned with openings in forward and rear ends of the body. The portion of the walls adjacent the opening in the forward end of the body is adapted for receipt within a blood vessel or cavity. Another portion of the walls has a side opening allowing communication with the main passage. A side tube encompasses the side opening and extends from the body. Resilient material having a central passage therethrough is located within the side tube. The resilient material is designed to be compressed and grip a catheter which is passed through the material, into and through the main passage. A leading portion of the catheter projects beyond the forward end of the body. Clearance is left between at least one of the walls of the main passage and the catheter to allow simultaneous passage of liquids through both the main passage and the catheter. Thus, the catheter holding device is used for a number of dual functions, e.g., the simultaneous measurement of the central venous pressure and transfusion of liquids into the blood vessel.

A catheter and catheter holding assembly comprising: longitudinally-extending walls defining an open-sided body having a main passage therethrough, at least a portion of said main passage being aligned with openings in forward and rear ends of said body, the portion of said walls adjacent openings in the forward end of the body being adapted for receipt within a blood vessel or cavity, a second portion of said walls having a side opening therethrough allowing communication with said main passage, and the portion of said walls adjacent the opening in the rear end of the body being adapted for connection to an intravenous system; a side tube extending from said body having one end encompassing said side opening and the other end being open; resilient material received within the side tube, said resilient material having a passage therethrough, said a catheter being removably passed therethrough into the main passage for projection from the forward end thereof with clearance being left between at least one of the walls of the main passage and the catheter so that fluid communication paths through the catheter and through the main passage external of the catheter can be simultaneously established; and means for cOmpressing the resilient material in the side tube to reduce the cross-section of the passage through the resilient material for sealingly gripping said catheter passing therethrough.
