Jewell, installed as Roy Keane's permanent successor on January 10, is keen to bring some new faces to Portman Road.
Jewell said: "We're always looking to improve the squad and we did try and get in a couple of players last week.
"They were at Premier League clubs, but said they didn't want a loan move and wanted to stay and fight for their place and I can understand that."
Jewell also wants to send some of his younger fringe players out on loan.
He added: "I've been impressed by the young pros, but I'd like to get them out on loan. Go and play some first-team football, get kicked a bit. It will be good for them as footballers."
