Abstract
A vascular access system and method of use for said system. The vascular access system generally comprises a body member; a shuttle member movably coupled to the body member; and a plurality of access needles fixedly coupled to the shuttle member and extending from the body member to penetrate a patient's skin.
Core Innovation
The invention provides a vascular access system and methods for its use, designed to enable medical professionals to achieve rapid and consistent vascular access without the need for additional monitoring or guidance systems such as ultrasound. The system is particularly suited for use in field settings or other conditions where traditional techniques, like the Seldinger technique, are impractical or impossible to implement.
The system comprises a body member adapted to be held against a patient's skin, a shuttle member movably coupled to the body member, and a plurality of access needles fixedly attached to the shuttle member and extending from the body member. These parallel, evenly spaced needles enable simultaneous penetration of the skin, optimizing lateral coverage of the targeted blood vessel region, such as the femoral artery. A guidewire can then be inserted through a needle upon confirmation of vascular access via blood aspiration.
The problem addressed by the invention is the lack of suitable vascular access methods for medical professionals operating outside controlled hospital environments, where there is often limited or no access to ultrasound or other external guidance systems. The system enables medical personnel, including paramedics and military medics, to obtain vascular access rapidly, safely, and repeatably without extensive expertise or advanced guidance equipment.
Claims Coverage
There are two independent claims covering multiple inventive features for vascular access systems.
Vascular access system with a body member, shuttle member, and plurality of parallel access needles
The system includes: - A body member with a base member and stand member - A shuttle member movably coupled to the body member - A plurality of hollow, blood vessel access needles parallel to one another and fixedly coupled to the shuttle member The shuttle member is advanceable along the body member in a controlled manner so that the needles simultaneously and evenly pierce the patient's skin. Vascular access is indicated by blood aspiration from at least one of the needles, and this occurs without requiring additional monitoring or guidance systems.
Vascular access system with a control assembly for controlled advancement
The system comprises: - A body member - A shuttle member movably coupled to the body member - A plurality of hollow, blood vessel access needles parallel to one another and fixedly coupled to the shuttle member - A control assembly operably coupled to the body member and the shuttle member The control assembly is adapted to provide a controlled rate of advancement of the shuttle member along the body member so that the plural needles pierce the patient's skin simultaneously and evenly, allowing for vascular access confirmation without the use of additional monitoring or guidance systems.
The independent claims provide broad coverage for vascular access systems combining a movable shuttle member with multiple parallel access needles and optional control assemblies, enabling vascular access without external guidance devices.
Stated Advantages
Provides rapid, safe, and repeatable vascular access without the need for additional monitoring or guidance systems such as ultrasound.
Facilitates vascular access by medical professionals in field or non-hospital settings where standard techniques may be impractical or impossible.
Reduces dependence on extensive expertise or external equipment for successful vascular access.
Documented Applications
Obtaining vascular access to arteries such as the femoral artery and radial artery.
Accessing veins for placing IVs, IV filters, and similar medical devices.
Allowing field personnel such as paramedics and military medics to achieve vascular access in environments lacking ultrasound or advanced guidance systems.
