Sterile Aquasonic® 100 Ultrasound Gel (Parker Laboratories)
Not Found
No
The device is a sterile ultrasound coupling gel, which is a passive material used to facilitate ultrasound transmission. The description focuses on its physical and biological properties, not on any computational or analytical capabilities.
No
The device is an ultrasound coupling gel, which facilitates the transmission of sound waves for diagnostic imaging but does not directly provide therapy or therapeutic benefit to a patient.
No
Explanation: This device is an ultrasound coupling gel, which facilitates diagnostic imaging by providing acoustic coupling. It does not perform any diagnostic function itself but is an accessory used with diagnostic ultrasound equipment.
No
The device is a physical gel intended for use as a coupling medium in ultrasound procedures. The description focuses on its physical and chemical properties, sterility, and biocompatibility, not software functionality.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use of Konix® Sterile Gel is as a contact medium for ultrasonic and electrical transmission. It facilitates the transmission of sound waves between the patient and the ultrasound transducer. It is a coupling agent, not a device that performs a diagnostic test on a sample taken from the body.
- Device Description: The description focuses on the physical and chemical properties of the gel that make it suitable for ultrasound transmission and biocompatibility. It does not describe a device that analyzes biological samples.
- Lack of In Vitro Testing: The performance studies mentioned include acoustic tests, sterility tests, and biocompatibility tests (cytotoxicity, sensitization, irritation, systemic toxicity). These are relevant to the safety and performance of a topical or intracavitary medical device, but they are not the types of studies typically associated with IVDs, which involve testing biological samples in vitro.
- No Analysis of Biological Samples: The device does not analyze blood, urine, tissue, or any other biological sample to provide diagnostic information. Its role is purely to improve the quality of the ultrasound image by facilitating sound transmission.
In summary, Konix® Sterile Gel is a medical device used in conjunction with diagnostic ultrasound procedures, but it is not an IVD itself. It is a coupling agent that enables the diagnostic procedure, rather than performing the diagnostic test.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Performance Test: The results of the acoustic tests indicated that "no effect of attenuation or impedance mismatch with the gels could be observed in imaging of the test objects in numerous real time sweeps." The report stated that the acoustic impedance of 1.49 kg/m²s for the Konix® gel is close to the reported mean human dermis of 1.6 kg/m²s, and should minimize reflection loses and generation of reverberant echoes when gel layers of at least 1/4 wavelength are employed. The speed of sound of 1516 m/s is very close to the 1518 m/s reported for skin, and this should minimize refract errors for oblique incidence into skin after passage through finite thicknesses of gel and keep elevation focus for RTV lense material as designed. In conclusion, the researchers stated that the "acoustic properties of this gel are very similar to those of other coupling gels commonly employed.
Sterility and Shelf-Life: Independent testing confirmed that Konix® Sterile Gel is free of microbes following sterilization radiation. No aerobic mesophilic bacteria were present in either tryptone soy broth or fluid thioglycollate medium after 14 days of storage at 30℃. Storage stability testing at 22° and 40°C indicated that Konix® Sterile Gel is stable for three years at ambient temperatures when pH, density, and appearance were measured. Additionally, examination of packages over a three year period showed that there was no microbial growth, thus confirming long-term package integrity and sterility.
Additional Tests: In vitro cytotoxicity, in vivo sensitization, irritation tests, and mouse systemic toxicity tests were conducted with the Konix® Sterile Gel according to standard protocols. All tests proved negative for cytotoxicity, sensitization, and systemic toxicity.

Production
Konix® Sterile Gel is produced in a closed-loop system so that contamination is eliminated. The carbomer and monopropylene glycol are added to water in a mixer. There is an in-process quality control that confirms the correct percentage of ingredients. The preservatives are then added, and the pH is adjusted. A final analysis is conducted on the mixture, and then the product is filled. The product is produced in a 100,000 class clean room with Hepa filters. The process includes a vacuum process so that bubbles cannot form. After production, the sterile gel is gamma irradiated according to accepted standards, to assure sterility. The product has a three year shelf-life.

Carbomer, triethanolamin, and monopropylene glycol constitute the ingredients that form the gel. These are common ingredients used for this purpose. Methylchloroisothiazolinone (5-chloro-2-methyl-4-isothiazolin-3-one) is a preservative with antibacterial and antifungal effects within the group of isothiazolinones. It is effective against gram-positive and gram-negative bacteria, yeast, and fungi. Methylisothiazolinone, is a powerful general biocide and preservative within the group of isothiazolinones, often used in personal care products.
