Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sensor guidewires face challenges in powering wireless transceiver units during medical procedures, particularly in sterile environments, where internal batteries are not suitable for disposable devices and pose risks during sterilization processes.
Innovation Solution
A detachable and rechargeable battery pack or holder is provided for the transceiver unit, allowing for safe sterilization and reuse, with mechanisms to prevent improper reuse and re-sterilization, and enabling both wired and wireless setups.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an internal battery is integrated into the sensor guidewire for wireless operation, then the device can function autonomously during procedures, but the battery cannot be sterilized separately and poses risks during sterilization processes
Solution Approach 1:
The device is divided into separable components: a disposable sensor guidewire and a reusable transceiver unit with battery. This segmentation allows the battery to be isolated in the reusable unit, enabling proper sterilization of the guidewire while protecting the battery from sterilization damage.
Solution Approach 2:
The battery is extracted from the disposable guidewire and placed in a separate reusable transceiver unit. This extraction removes the battery from the sterilization process, eliminating the risk of battery damage during sterilization while maintaining wireless operation capability.
2Reliability
If a disposable sensor guidewire with internal battery is used, then single-use compliance is achieved, but the battery cannot be recharged or reused, increasing environmental impact
Solution Approach 1:
The system separates the disposable component (sensor guidewire) from the reusable component (transceiver unit with battery). This allows the battery to be reused across multiple procedures while the guidewire remains single-use, reducing battery waste while maintaining compliance.
Solution Approach 2:
The reusable transceiver unit with battery is recovered and reused across multiple procedures, while only the disposable guidewire is discarded. This recovers the expensive battery resource and reduces environmental impact while maintaining single-use compliance for the sterile component.
3Object-affected harmful factors
If the battery is integrated into the transceiver unit for wireless communication, then electrical insulation is improved, but additional power supply infrastructure is required
Solution Approach 1:
The battery is extracted and placed in the transceiver unit, eliminating the need for electrical connections between the guidewire and external power sources during procedures. This maintains electrical insulation while the battery self-contained nature reduces power supply infrastructure complexity.
Data Source
AI summary
A transmitter unit with an attachable energy source is provided for a sensor guidewire. The transmitter unit is adapted to be connected to a proximal end of a sensor guidewire provided, at its distal end, with a sensor to measure a physiological parameter inside a patient. In some embodiments, the transmitter unit is adapted to wirelessly communicate by a communication signal with a communication unit, arranged in connection with an external device, in order to transfer measured physiological data to the external device. The attachable energy source can be a battery pack or battery holder provided with connecting electrical connecting surfaces. Preferably, the connection is protected from penetrating fluids by a protective seal.
