Medical Rack Mount With Rotating Posts for One-Handed Pump Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medical staff face difficulties in easily and securely mounting and detaching heavy infusion pumps and syringe pumps from racks due to the need to hold them with both hands, which can cause the rack to be pushed or moved unintentionally.
Innovation Solution
A medical device rack with rotatable mounting sections that include upper and lower posts for secure attachment and a lock mechanism, allowing devices to be mounted or detached with one hand, and an outlet terminal system for electrical connection using a spring mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the infusion pump and syringe pump are mounted by being entirely slid and pushed in the vertical direction to the rack from a front side, then the devices can be secured to the rack, but the rack itself may be pushed and moved backward, making it difficult for medical staff to surely mount the heavy devices
Solution Approach 1:
The supporting portion is designed to preliminarily support the weight of the medical device before complete mounting is achieved. When the device is being slid into the rack, the supporting portion (upper post and lower post) engages with the insertion holes to bear the device weight, preventing the rack from being pushed backward. This preliminary support action enables secure mounting without requiring two hands.
Solution Approach 2:
The supporting portion acts as an intermediary mechanism between the medical device and the rack structure. The upper post and lower post serve as intermediate support elements that transfer the device weight to the rack frame through the insertion holes, mediating the force transmission to prevent rack movement while enabling secure attachment.
2Reliability
If the medical device is held with both hands for mounting or detaching, then the device can be securely handled, but it is difficult to operate since the rack may be pushed or moved unintentionally
Solution Approach 1:
The supporting portion provides preliminary support to the medical device weight during the mounting and detaching operations. When the device is inserted or removed, the upper post and lower post engage with the insertion holes to bear the device weight, enabling secure one-handed operation without requiring the user to hold the device with both hands.
Solution Approach 2:
The mounting and detaching mechanism is designed to be self-supporting. The supporting portion automatically engages with the insertion holes to bear the device weight during operation, eliminating the need for the user to manually support the device weight with both hands. The system serves itself by providing inherent weight support during the mounting/detaching process.
3Adaptability or versatility
If the infusion tube and syringe are held by being passed in the horizontal direction instead of the vertical direction, then a plurality of infusion pumps and syringe pumps can be held by being vertically stacked in a rack, but the mounting operation becomes more complex
Solution Approach 1:
The mounting section is segmented into distinct functional components: the supporting portion (upper post and lower post) for weight bearing, the lock mechanism for securing, and the tray for positioning. This segmentation allows the horizontal passing configuration to achieve vertical stacking capability while maintaining simple mounting operations, as each segment performs a specific function that simplifies the overall mounting process.

AI summary
A rack (500) that supports medical devices (1, 1001) includes mounting sections (C1-C3). Each of the mounting sections (C1-C3) includes an upper post (535A) and a lower post (535B). The medical devices (1, 1001) includes a first hole (611) and a second hole (612). When the upper post (535A) is fitted into the first hole (611) and the lower post (535B) is fitted in to the second hole (612), the medical device (1, 1001) can be rotated around a shaft (CL) passing through the posts (535A, 535B) and the holes (611, 612). An outlet terminals (530) of the mounting section (C1-C3) can be surely and smoothly fitted into outlet terminal hole (570) of the medical device (1, 1001) by rotating the medical device (1, 1001) around the shaft (CL).
