Sealed Bag Antiseptic Applicator for Surgical Site Preparation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for applying antiseptic solutions before surgery are inefficient, leading to increased waste, potential bacterial contamination, prolonged anesthesia time, and higher operational costs due to the need for multiple sponges and application in a sterile environment.
Innovation Solution
A sealed bag applicator system that allows for the application of antiseptic solution outside the operating theater, using a resilient seal gasket and solution deployment pouch to ensure complete coverage and containment, with optional scrub brushes for thorough disinfection, and temperature monitoring to enhance patient comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple sponges are used to apply antiseptic solution, then complete coverage of surgical site is achieved, but waste increases and handling complexity increases
Solution Approach 1:
Multiple sponges are merged into a single reusable sponge holder that can be repeatedly immersed and used. The holder contains multiple sponges arranged to cover different areas of the surgical site, eliminating the need to discard and replace sponges after each use.
Solution Approach 2:
The sponge holder is designed to be recovered and reused multiple times. After each use, the holder is emptied, rinsed, and stored for subsequent use, rather than being discarded. This recovers the utility of the sponge holder while the sponges themselves are replaced as needed.
2Reliability
If antiseptic solution is applied in sterile operating theater, then aseptic technique is maintained, but time consumption increases and throughput decreases
Solution Approach 1:
The sponge holder is pre-assembled with multiple sponges before entering the operating theater. The antiseptic solution can be applied to the surgical site before anesthesia, allowing the sterile field preparation to begin in advance and reducing the time required during the surgical procedure.
3Reliability
If antiseptic solution is applied with scrubbing action, then bacterial dislodgement is enhanced, but solution splashing and spills increase
Solution Approach 1:
The sponge holder acts as an intermediary tool between the operator and the surgical site. It provides a controlled mechanism for applying antiseptic solution and performing scrubbing actions, reducing uncontrolled splashing and spills while maintaining effective bacterial dislodgement.
4Ease of operation
If antiseptic application is performed after anesthesia, then patient comfort is maintained, but anesthesia time increases and cost increases
Solution Approach 1:
The antiseptic application can be performed before anesthesia is administered. The sponge holder allows for systematic application of antiseptic solution to the surgical site while the patient is still awake but comfortable, eliminating the need to delay the procedure until after anesthesia.

AI summary
A device used for applying an antiseptic preparation to a surgical site of a patient prior to surgery outside of an operating theater. A loose-fitting bag is provided which encloses the surgical site by securing the open end(s) to the patient by closing means. A high friction scrub surface is provided in the bag. A method and apparatus are also provided for releasing antiseptic into the interior of the bag. The method provides that the surgical site can be scrubbed within the bag so as to properly prepare the skin for surgery. A temperature indicator for the antiseptic preparation is also provided.
