Blood Purification Apparatus Pre-Attachment Component Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current blood purification apparatuses verify medical components only after they are attached, leading to unnecessary disposal and sterility issues if the components are found inappropriate, causing a burden on medical institutions.
Innovation Solution
A blood purification apparatus with a reading unit capable of scanning component information from a sterile bag without opening it, using an information-holding unit such as bar codes or RF tags, allowing for pre-attachment verification of medical components against treatment information stored in the apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If medical component verification is performed after attachment to apparatus body, then treatment safety is improved, but medical component waste increases and sterility is compromised
Solution Approach 1:
The patent applies preliminary action by performing verification of the medical component's component information against treatment information before the medical component is attached to the apparatus body. The reading unit reads component information from an information-holding unit on the medical component, and the verifying unit compares it with stored treatment information, allowing verification to occur in advance while the medical component remains sealed in its sterile bag.
2Reliability
If medical component verification is performed after attachment to apparatus body, then treatment safety is improved, but sterility of medical component is compromised
Solution Approach 1:
The patent performs verification before attachment while the medical component is still sealed in its sterile bag. The reading unit reads component information from the information-holding unit without requiring the bag to be opened, and the verifying unit completes verification in advance, thus maintaining sterility while ensuring treatment safety.
3Measurement precision
If medical component is taken out of sterile bag for verification, then verification accuracy is improved, but sterility is lost
Solution Approach 1:
The patent introduces an information-holding unit as an intermediary that carries component information on the medical component or its packaging. The reading unit reads this information without needing to open the sterile bag or handle the medical component itself, thus maintaining sterility while achieving accurate verification through the intermediary information carrier.
4Loss of substance
If medical component verification is performed before attachment, then medical component waste is reduced, but verification capability must be enhanced
Solution Approach 1:
The patent uses an information-holding unit as an intermediary that simplifies pre-attachment verification. Instead of requiring complex verification of the actual medical component, the system reads component information from the information-holding unit (such as a barcode or RFID tag on the packaging), making pre-attachment verification feasible without excessive device complexity.

AI summary
A blood purification apparatus including an apparatus body to which a medical component for giving blood purification treatment to a patient is to be attached; a storage unit that stores treatment information regarding the blood purification treatment for the patient; a reading unit capable of reading component information of the medical component held by an information-holding unit; and a verifying unit capable of comparing the component information read by the reading unit and the treatment information stored in the storage unit and verifying whether or not the medical component is appropriate for being attached to the apparatus body. The medical component is sealed in a sterile bag before being attached to the apparatus body. Furthermore, the reading unit is capable of reading the component information in the information-holding unit from an outside of the sterile bag.
