Powered Intraosseous Driver for Rapid Vascular Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional intravenous access methods often fail in patients with limited or inaccessible veins, leading to delayed or impossible administration of life-saving drugs and fluids, particularly in emergency situations where rapid vascular access is critical.
Innovation Solution
A powered driver device capable of inserting an intraosseous device into bone marrow, providing emergency vascular access by using a motor and gear assembly to rotate a drive shaft and accommodate various insertion sites, with a power supply for multiple insertions and a design that includes sound dampening and a sealed housing to prevent contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional intravenous access methods are used, then vascular access can be established in patients with accessible veins, but access fails in patients with limited or inaccessible veins leading to delayed or impossible administration of life-saving drugs and fluids
Solution Approach 1:
Instead of attempting to access the venous system directly through traditional IV methods, the invention inverts the approach by accessing the vascular system through the bone marrow (intraosseous route). The powered driver inserts a needle through the bone to reach the bone marrow cavity, providing an alternative pathway to administer fluids and medications when conventional IV access fails.
Solution Approach 2:
The invention introduces an intermediary approach by using the bone marrow as a mediator to reach the vascular system. When direct venous access is impossible, the intraosseous route serves as an intermediate pathway, allowing fluids and medications to be delivered into the circulatory system through the bone marrow cavity.
2Ease of operation
If manual IV insertion is performed in emergency situations, then access can be established in stable patients, but excessive motion and difficulty in seeing the target make accessing the venous system very difficult in field conditions
Solution Approach 1:
The powered driver performs the insertion action automatically once the target site is selected, eliminating the need for manual manipulation and steady hand requirements. The operator simply positions the device and activates the powered insertion mechanism, which self-performs the penetration task regardless of patient motion or environmental conditions.
Solution Approach 2:
The invention replaces the manual mechanical skill-based insertion process with an automated powered mechanical system. The powered driver uses motorized actuation to perform the insertion, substituting the operator's manual dexterity and visual targeting skills with an automated mechanism that is less susceptible to the challenges of field conditions.
3Productivity
If repeated probing with sharp needles is performed to establish IV access, then access may eventually be achieved, but the process is time-consuming and may require invasive procedures
Solution Approach 1:
The powered driver performs the difficult penetration action in a single preliminary action, eliminating the need for repeated probing attempts. The motorized insertion mechanism delivers the needle through the bone and into the bone marrow cavity in one continuous motion, achieving vascular access without multiple failed attempts or escalating to more invasive surgical procedures.
4Reliability
If a powered driver with motor and gear assembly is used to insert intraosseous device, then rapid and reliable vascular access is achieved, but the device complexity increases
Solution Approach 1:
The powered driver is designed as a multi-functional device that can access multiple bone sites (humerus, tibia, sternum) and perform various insertion tasks. This universality justifies the increased complexity by providing a single reliable device that can handle different clinical scenarios and patient anatomies, rather than requiring multiple specialized tools.
