Solution Overview
Problem
Conventional medicinal liquid supply apparatuses cannot provide a precise, fixed volume of medication for patients with specific needs and lack the ability to allow additional medication administration during a paramedic's absence, posing risks for patients requiring minute or variable dosages.
Innovation Solution
A medicinal liquid supply apparatus featuring a fixed-type volume controller with multiple branch hoses and a double hose system, allowing precise control and an additional arbitrary supply mechanism via a button-activated storage tube, enabling both precise fixed dosing and supplementary medication delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional medicinal liquid volume controller is used, then the device is simple and easy to operate, but it cannot control the volume of medicinal liquid minutely and may cause excessive or inadequate dosing
Solution Approach 1:
The medicinal liquid supply is divided into two independent channels: a fixed-type volume controller for precise predetermined dosing and an arbitrary supply controller for additional dosing. Each channel operates independently with its own control mechanism, allowing the system to provide both minute fixed-volume control and flexible additional supply without compromising precision
Solution Approach 2:
A T-shaped connector is introduced as an intermediary component to merge the fixed-type volume controller channel and the arbitrary supply controller channel. This connector allows both control systems to interface with the same medicinal liquid hose without interfering with each other's precision control mechanisms
2Adaptability or versatility
If a fixed-type volume controller is used to ensure precise dosing, then dosing accuracy is improved, but the system cannot allow additional medication administration during paramedic's absence
Solution Approach 1:
The control system is segmented into two independent functional units: the fixed-type volume controller that maintains dosing safety through predetermined accurate dosing, and the arbitrary supply controller that provides adaptability for additional medication when needed. The segmentation allows each unit to excel at its specific function without compromising the other
Solution Approach 2:
The system transitions from a static fixed-volume control to a dynamic dual-control system where the arbitrary supply controller can be activated based on real-time patient needs. The dynamic configuration allows the system to adapt between fixed precise dosing and flexible additional supply modes while maintaining overall dosing safety through the T-shaped connector design
3Ease of operation
If a button-activated arbitrary supply mechanism is added, then the ability to supply additional medication is improved, but the device complexity increases
Solution Approach 1:
The arbitrary supply function is extracted as a separate independent controller with its own button-activated mechanism. This extracted component connects to the main system through the T-shaped connector, allowing users to operate the additional supply function independently without affecting the fixed-type volume controller's precision mechanism
Solution Approach 2:
The T-shaped connector serves multiple functions: it connects the fixed-type volume controller channel, receives the arbitrary supply controller input, and merges both flows into the single medicinal liquid hose. This universal connector component enables the system to achieve multiple functions (precise dosing + flexible additional supply) without proportionally increasing overall system complexity

AI summary
Disclosed therein is a medicinal liquid supply apparatus, which includes a fixed-type medicinal liquid supply volume controller adapted to supply medicinal liquid only as much as a paramedic sets and fixes and an arbitrary medicinal liquid supply volume controller adapted to allow a patient or the third party to arbitrarily supply the medicinal liquid as occasion demands during the paramedic's absence, thereby effectively supplying the medicinal liquid according to the patient's disease and pain conditions. The medicinal liquid supply apparatus includes: a fixed-type medicinal liquid supply volume controller having a plurality of medicinal liquid branch hoses opened and closed by a controller and a medicinal liquid transfer hose always opened, the medicinal liquid branch hoses and the medicinal liquid transfer hose being connected to an inflow part and an outflow part of a medicinal liquid control line thereof; and an arbitrary medicinal liquid supply volume controller connected to a double medicinal liquid hose having a branch tube connected to the medicinal liquid transfer hose of the fixed-type medicinal liquid supply volume controller, the arbitrary medicinal liquid supply volume controller having a medicinal liquid storing tube for storing the medicinal liquid transferred through the double medicinal liquid hose to arbitrarily and additionally supply the medicinal liquid by a button body.
