Abstract

Disclosed are a blood collection system with user-adjusted pressure management and related methods. A catheter system may include a catheter adapter, a catheter extending distally from the distal end of the catheter adapter, and a needle hub coupled to the catheter adapter. The needle hub may be transparent, and a needle may be secured within the needle hub. The catheter system may also include a flow control plug coupled to the proximal end of the needle hub. In some embodiments, a flashback pathway may be disposed between an outer surface of the flow control plug and an inner surface of the needle hub. In some embodiments, the catheter system may include an inner barrel and an outer barrel, and the inner barrel and the needle hub may be configured to move proximally within the outer barrel to retract the needle. The flashback pathway may be disposed between an outer surface of the needle hub and an inner surface of the inner barrel.

Description

technical field [0001] The present disclosure relates to medical devices, and more particularly, the present disclosure relates to a blood collection system with user-adjusted pressure management, and related devices and methods. Background technique [0002] Intravenous catheters are commonly used for various infusion therapies. For example, infusion fluids such as saline solution, various drugs, and total parenteral nutrition can be infused into a patient using an intravenous catheter. Intravenous catheters may also be used to draw blood from the patient. [0003] Common types of intravenous catheters include peripheral intravenous catheters ("PIVCs"), peripherally inserted central catheters ("PICCs"), and midline catheters. Intravenous catheters may include "trocar" catheters that fit over a needle with a sharpened distal tip. The sharp distal tip can be used to pierce the patient's skin and vasculature. Insertion of the intravenous catheter into the vasculature may b...
