Syringe Stand for Heat-Resistant Bone Cement Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for transferring heat-activated bone cement compositions into syringes often require complex pumps and tubes, and users must physically hold the syringe, which can cause the cement to set prematurely due to body heat.
Innovation Solution
A syringe stand with a base and top portion featuring an aperture that engages the syringe's nozzle or plunger, maintaining the syringe in an upright position and allowing for secure, heat-resistant transfer of the cement without manual handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the syringe is held manually during cement transfer, then the transfer process is simple, but the body heat causes the heat-activated bone cement to set prematurely
Solution Approach 1:
The patent introduces a syringe holder as an intermediary device between the user and the syringe. This holder serves as a thermal barrier that prevents body heat from transferring to the syringe and causing premature cement setting, while still allowing easy insertion and removal of the syringe for filling and injection operations
2Extent of automation
If complex pumps and tubes are used to transfer cement, then the transfer can be automated, but the device complexity increases significantly
Solution Approach 1:
The patent extracts the essential function of automated cement transfer by removing the syringe from manual handling and placing it in a fixed holder position. This allows gravity-assisted or pressure-driven cement filling without requiring complex pumping mechanisms, tubes, or automated injection systems
Solution Approach 2:
The syringe holder enables the cement transfer process to be self-service by positioning the syringe in a fixed, upright orientation that allows cement to be easily filled from above or pushed in without requiring active manipulation during the filling process

AI summary
A stand for use with a syringe is disclosed. The stand includes a base and a clip affixed to the base. The clip engages a portion of the syringe so as to removably secure the syringe to the stand in a position such that the distal end of the syringe is spaced vertically away from the base. Preferably, the syringe includes a handle extending outwardly from a barrel of the syringe, and the feature which the clip engages includes the handle of the syringe.
