Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing syringe holding systems for medical pumps are complex, costly, and inefficient, particularly when trying to administer a second drug or supplement, as they often require additional space and manual handling, which can be tedious and distracting for caregivers.

Innovation Solution

A syringe holding system with a body, elongated finger, and stop member that allows for detachable mounting on a medical pump, enabling pivotal movement and secure retention of the syringe in a desired orientation, using a clip to clamp onto the pump handle and a mounting hole for direct syringe insertion or use with an adaptor, all made from cost-effective plastic materials.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If a motorized infusion pump with a syringe mounted thereon and a motor driven plunger driver assembly is used, then the syringe can be automatically moved to expel fluid, but the mounting mechanism becomes complex and costly to produce

Engineering Contradiction:

Improveautomatic syringe movementVSAvoidmounting mechanism complexity

Core Design Contradiction:

Extent of automationVSDevice complexity

Solution Approach 1:

The invention extracts the syringe mounting function from the complex motorized pump system and creates a separate, simple holder that can be independently attached to the pump. This holder uses basic mechanical elements (clamp, finger, stop member) rather than complex motorized mounting mechanisms, thereby reducing overall system complexity while maintaining automation capability through the pump's existing motorized components

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The syringe mounting system is segmented into distinct functional components: a holder body, a clamp for securing the syringe, a finger for positioning, and a stop member for limiting movement. This segmentation allows each component to be optimized independently and simplifies the overall mounting mechanism compared to integrated complex systems

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If a peristaltic pump or reciprocating driver is used to deliver fluid, then the system can administer drugs, but additional space is required for a second pole stand to hang the syringe or secondary bag

Engineering Contradiction:

Improveability to administer second drugVSAvoidbedside space requirement

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The syringe holder is designed with multi-functionality to accommodate both primary and secondary syringes on a single unit. The holder can securely mount syringes in various orientations and positions, allowing the same device to serve multiple purposes: administering primary drugs, secondary drugs, and providing bolus injections without requiring separate pole stands or additional bedside space

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of operation

If a caregiver manually holds the syringe, then the syringe can be positioned for administration, but the task becomes tedious and detracts from two-handed caregiver tasks

Engineering Contradiction:

Improvesyringe positioningVSAvoidcaregiver task efficiency

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The syringe holder is designed to be self-positioning and self-securing. The finger component automatically positions the syringe in the correct orientation, and the clamp secures it in place without requiring continuous manual adjustment. This self-service capability eliminates the need for caregivers to continuously hold and reposition syringes, thereby improving productivity and allowing for two-handed tasks

Inventive Principle:

Principle #25Self-service

4Reliability

If a complex motorized mounting mechanism is used for syringe attachment, then the syringe can be securely mounted, but the production cost increases

Engineering Contradiction:

Improvesyringe mounting securityVSAvoidproduction cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The syringe holder is designed as a simple, inexpensive component that can be easily manufactured using conventional molding techniques. Rather than using expensive, complex motorized mounting mechanisms, the holder uses basic plastic components (body, finger, clamp, stop member) that are cost-effective to produce and can be disposable or easily replaceable, thereby reducing production costs while maintaining reliable syringe mounting through well-designed mechanical engagement

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

AI summary

A syringe holder includes a body with a syringe retainer, an elongated finger and a stop member connected to the body. The finger inserts longitudinally into a socket on a pump without the aid of tools and permits the holder to move in multiple planes. The stop member limits such movement. The stop member can include a clip for releasably clamping onto a portion of a pump. The syringe retainer can include a hole in the body and may optionally include an adaptor mounted in or extending into the hole for detachably attaching a syringe. The syringe holder can be incorporated into a tube set assembly or an infusion system.
