Button-Cell Battery Integration in Sensor Guide Wire Transmitter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sensor guide wire assemblies with wireless transmission require additional energy sources like separate battery packs, increasing complexity and size, and necessitating separate sterilization, which complicates medical procedures.
Innovation Solution
A transmitter unit with a housing that contains a printed circuit board, a button-cell type battery, and a micro-switch activation mechanism, allowing for wireless data transfer of physiological parameters, reducing size and complexity by integrating the battery within the unit and enabling easy sterilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate battery pack or battery holder is used to power the wireless transmitter unit, then the wireless transmission function is enabled, but the device size and complexity increase
Solution Approach 1:
The patent integrates the battery directly into the transmitter unit housing, combining what were previously separate components (battery pack + transmitter unit) into a single unified device. This eliminates the need for a separate battery pack or battery holder, thereby reducing device complexity while maintaining wireless transmission capability
Solution Approach 2:
The transmitter unit housing is designed to serve multiple functions: it houses the electronic circuitry, contains the battery, and provides the external interface for wireless transmission. This multi-functional design eliminates the need for separate battery packaging components
2Adaptability or versatility
If a separate battery pack or battery holder is used, then the wireless transmission function is enabled, but additional sterilization is required
Solution Approach 1:
By integrating the battery into the transmitter unit housing, the patent creates a single sterilizable component. This eliminates the need for separate sterilization of battery packs or holders, simplifying the sterilization process and reducing the risk of contamination
Solution Approach 2:
The integrated design allows the entire transmitter unit (including battery) to be treated as a disposable or easily sterilizable component, eliminating the need for complex re-sterilization procedures
3Use of energy by moving object
If a separate battery pack is used, then power supply is provided, but the device size increases
Solution Approach 1:
The battery is integrated within the transmitter unit housing, eliminating the need for a separate battery pack. This consolidation reduces the overall device volume by removing redundant packaging and connection components between the battery and transmitter

AI summary
A sensor guide wire assembly having a button-cell type battery includes a transmitter unit configured to be connected to a sensor guide wire that is insertable into a patient to measure a parameter, the transmitter unit being configured to wirelessly transfer data representing the measured parameter to a communication unit. The transmitter unit includes a housing, a printed circuit board holder disposed in the housing, and a printed circuit board disposed in the housing and held by the printed circuit board holder. The printed circuit board includes a plurality of electrical contacts. A slider is slidable from a location outside the housing, the slider including a protrusion extending into an area inside the housing. A space within the housing is configured to hold one or more batteries. The slider is slidable from a first position, at which a micro-switch is not activated, to a second position, at which the micro-switch is activated by the protrusion of the slider, which allows power to be provided to the printed circuit board.
