Movable Bottle Receiver for Injection Device with Pivoting Spike
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bottle holders for injection devices are cumbersome and prone to fluid leakage and soiling, as they require complex and time-consuming procedures for loading and unloading storage bottles of varying sizes, and lack stability, leading to potential spills during bottle exchange.
Innovation Solution
A bottle holder with a movable receiver guided by a spring mechanism and flexible holding elements that adapt to different bottle sizes, allowing for easy and centered piercing of the storage bottle's opening, and a pivoting mechanism to prevent fluid spillage during bottle removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cup-shaped bottle receiver is used to hold storage bottles, then bottles can be received and held, but the loading procedure becomes complicated and time-consuming requiring skilled operators
Solution Approach 1:
The puncturing spike is pre-positioned at the bottom of the bottle receiver in a ready-to-pierce position. When a bottle is inserted, the spike automatically pierces the seal without requiring manual intervention or complex alignment procedures, thereby simplifying the loading operation while ensuring reliable bottle holding and fluid connection.
2Device complexity
If the bottle receiver has a fixed internal diameter, then the structure is simple, but it cannot accommodate storage bottles of various sizes
Solution Approach 1:
The bottle receiver is designed with a flexible holding element that can adapt its shape and dimensions to accommodate storage bottles of various sizes. The flexible material allows the receiver to deform and conform to different bottle diameters, providing universal compatibility while maintaining structural simplicity. This dynamic adaptation enables the same receiver to securely hold both small and large bottles without requiring multiple fixed-size receivers.
3Ease of operation
If the storage bottle is pulled out vertically upward for removal, then the removal is simple, but residual fluid drips out causing soiling
Solution Approach 1:
Instead of removing the bottle vertically upward which causes fluid to drip downward, the invention inverts the removal direction by pivoting the bottle holder horizontally. This causes the bottle to be pulled out in a horizontal direction, preventing gravity-driven fluid dripping and eliminating the soiling problem while keeping the removal operation simple.
4Manufacturing precision
If the puncturing spike is fixed at the bottom center, then the piercing position is precise, but the bottle receiver lacks stability and may be knocked over
Solution Approach 1:
The invention transfers the piercing function from a fixed bottom-center spike to a movable spike mechanism that operates in a different dimensional space. The spike is positioned and actuated through a pivoting motion of the entire bottle holder assembly, allowing precise piercing through rotational movement rather than relying on a fixed vertical spike. This dimensional change stabilizes the floor stand while maintaining accurate pierce point positioning.

AI summary
The invention relates to a bottle holder (1) for an injection or infusion device, with a bottle receiver (2) for receiving a storage bottle, and with a spike secured on the bottle holder (1) for the purpose of punching an outlet opening into the storage bottle, or a holding means (3) for applying an exchangeable spike (4). In a development of such a bottle holder with which the infusion or injection device can be equipped as easily and as quickly as possible with a filled storage bottle, the invention proposes that the bottle receiver (2) is movable with respect to the spike (4) or with respect to the holding means (3) for the spike (4), and, when the bottle receiver (2) moves in the direction of the spike (4), a storage bottle arranged in the bottle receiver (2) is placed onto the spike (4) in such a way that the spike (4) punches an outlet opening into the storage bottle.
