Powered Driver for Intraosseous Bone Marrow Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Establishing vascular access in patients is challenging, especially in emergency situations where traditional intravenous access is difficult or impossible due to anatomical constraints, motion, or depletion of accessible veins, leading to delayed or impossible administration of life-saving drugs and fluids.
Innovation Solution
A powered driver apparatus and method for inserting an intraosseous device into bone marrow, which includes a housing with a motor, drive shaft, power supply, and light, allowing for rapid and controlled access to the vascular system by penetrating bone and engaging an intraosseous device, facilitating drug and fluid administration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional intravenous access is used, then vascular access can be established, but it becomes difficult or impossible in emergency situations due to anatomical constraints, motion, or depletion of accessible veins
Solution Approach 1:
The patent introduces bone marrow as an intermediary access site between the external environment and the vascular system. When traditional IV access fails due to anatomical constraints, motion, or vein depletion, the intraosseous device provides an alternative pathway through the bone marrow cavity, which is always accessible and directly communicates with the vascular system, thereby resolving the contradiction between reliability and ease of operation
Solution Approach 2:
The patent changes the access parameter from peripheral veins to the central bone marrow cavity. This parameter change allows access to the vascular system through a different anatomical route that is not affected by vein depletion, anatomical constraints, or motion, thereby improving both reliability and ease of operation in emergency situations
2Reliability
If repeated needle probes are used to establish IV access, then vascular access may be achieved, but it causes delays and increases procedural complexity
Solution Approach 1:
The patent performs preliminary action by pre-positioning the intraosseous device in the bone marrow cavity before emergency treatment is needed. The device is inserted through the skin and into the bone marrow cavity in a single procedure, establishing a ready-made access pathway that eliminates the need for repeated needle probes and time-consuming attempts to access peripheral veins during emergency situations
Solution Approach 2:
The bone marrow cavity serves as a preliminary intermediary structure that is accessed once and then maintains continuous communication with the vascular system. This eliminates the need for repeated attempts to access peripheral veins, thereby reducing time loss and increasing the success rate of vascular access
3Reliability
If invasive procedures are used to establish IV access, then vascular access can be achieved, but it increases procedural complexity and risk
Solution Approach 1:
The patent uses the bone marrow cavity as a simple intermediary structure that provides direct access to the vascular system. The intraosseous device is a relatively simple needle-like instrument that can be inserted through the skin into the bone marrow cavity, avoiding the need for complex invasive procedures such as central line placement or surgical access, thereby reducing procedural complexity while maintaining high reliability
4Adaptability or versatility
If conventional IV sites are used, then vascular access is possible, but it becomes unavailable in patients with chronic disease, elderly patients, or those with depleted veins
Solution Approach 1:
The patent makes the bone marrow cavity a universal access site that is available in all patients regardless of age, chronic disease status, or vein depletion. The intraosseous device can be inserted into the bone marrow cavity in patients of all ages and conditions, providing a universal alternative to conventional IV sites that are selectively unavailable in certain patient populations, thereby improving both adaptability and reliability
Solution Approach 2:
The bone marrow cavity serves as a universal intermediary access point that bypasses the need for peripheral veins. Since the bone marrow cavity is present in all patients regardless of their vascular status, this intermediary structure provides reliable access in patients with chronic disease, elderly patients, and those with depleted veins, thereby improving both adaptability and reliability across diverse patient populations
